- the cap device according to the first embodiment of the present invention comprises a cap body 50 , and a cap cover 100 provided on the cap body 50 to define a space therein to contain an additive in the space.
- the cap device further has a valve means to allow the space defined by both the cap body 50 and the cap cover 100 to selectively communicate with an interior of a bottle 13 .
- the cap body 50 is tightened to an externally threaded mouth 12 of the bottle 13 , with a funnel part 52 integrally formed in the cap body 50 to discharge the additive into the bottle 13 through a lower end thereof.
- the cap cover 100 is provided on the cap body 50 to cover an open upper end of the cap body 50 while defining the space inside both the cap body 50 and the cap cover 100 to contain the additive in the space.
- the valve means comprises a valve member V having a conical valve part 14 acting as a valve seat to be brought into close contact with or spaced apart from the lower end of the funnel part 52 of the cap body 50 .
- the conical valve part 14 of the valve member V thus closes or opens the lower end of the funnel part 52 according to the rotating action of the cap body 50 relative to the externally threaded mouth 12 of the bottle 13 .
- a plurality of radial ribs 124 extend outward from an external surface of the conical valve part 14 in radial directions such that outside ends of the radial ribs 124 are supported on the inner surface of a neck of the bottle 13 .
- a circular ring 24 having a predetermined thickness integrally surrounds the outside ends of the radial ribs 124 .
- the valve means separates from the lower end of the funnel part 52 , thus, opening the lower end of the funnel part 52 of the cap body 50 . Therefore, the space defined by the cap body 50 and the cap cover 100 of the cap device communicates with the interior of the bottle 13 , as shown in FIGS. 3 a and 3 b .
- the additive is thus discharged from the space defined by the cap body 50 and the cap cover 100 into the bottle 13 to be mixed with a material contained in the bottle 13 to produce a mixture.
- a vacuum pressure may act on the surface of the additive contained in the space of the cap device, when the cap cover 100 is completely closed.

- the additive flows from the space 51 of the container 50 into the bottle 13 through a plurality of spaces defined between the radial ribs 222 - 1 , thus being added to a bottled material to prepare a desired mixture.
- the inner sidewall 102 of the cap body 100 B is inserted into the mouth 10 of the bottle 13 when the cap body 100 B is tightened to the mouth 10 of the bottle 13 .
- the cap body 100 B is also opened at the upper end thereof, thus having the open upper end 104 . That is, the open upper end 104 of the cap body 100 B is projected upward from the remaining part of the cap body 100 B, and has an external thread on the outer circumferential surface thereof, with a plurality of air paths 105 (see FIG. 8 ) vertically provided on the externally threaded outer circumferential surface of the open upper end 104 of the cap body 100 B.
- the air paths 105 guide atmospheric air to a vent hole H of the additive container 50 , as will be described in detail later herein.
- the additive container 50 which is a cylindrical body, is opened at the upper and lower ends thereof, as shown in FIG. 6 .
- the additive container 50 has the flanged discharging port 52 at a bottom wall thereof.
- the flanged discharging port 52 is projected downward from the bottom wall of the container 50 , and is inclined upward and inward on a lower end surface thereof, thus providing a second inclined surface, as best seen in FIG. 6 .
- the flanged discharging port 52 is able to be in close contact with the annular groove 222 - 2 of the valve means 222 of the cap body 100 B when the valve means 222 is closing the discharging port 52 .
- the flanged discharging port 52 is in linear contact with the annular groove 222 - 2 of the valve means 222 , thus providing a higher contact pressure which prevents the additive from undesirably leaking from the container 50 into the bottle 13 .
- the additive container 50 defines the space 51 therein to contain the additive in the space 51 .
- the additive container 50 is also rounded along an inside corner of the bottom wall thereof, thus providing a rounded surface S on the inside corner of the bottom wall. Due to the rounded surface S, the additive is smoothly discharged from the space 51 of the container 50 into the bottle 13 through the flanged discharging port 52 in response to an operation of the valve means 222 to open the flanged discharging port 52 .
- the cap device of the third embodiment further includes a means for locking the cap cover 100 A to the upper end of the additive container 50 while allowing the container 50 to move vertically, in conjunction with a rotation of the cap cover 100 A.
- the locking means includes an outside locking part 53 that is provided around the outer circumferential surface of the upper end of the additive container 50 .
- the locking means further includes an inside locking part 111 that is provided around the inner circumferential surface of the cap cover 100 A to engage with the outside locking part 53 of the container 50 .
- the additive container 50 is locked to the cap cover 100 A by engagement of the outside locking part 53 with the inside locking part 111 , so that the cap cover 100 A is removed from the container 50 when the cap cover 100 A is rotated with an external rotating force which is stronger than a predetermined reference force.
- the container 50 moves vertically in conjunction with the rotation of the cap cover 100 A.
- the additive container 50 has the vent hole H at a predetermined position on the upper portion of a sidewall thereof.
- the vent hole H of the container 50 is closed by the upper end 104 of the cap body 100 B.
- the cap cover 100 A is loosened from the upper end 104 of the cap body 100 B as shown in FIG. 7 a , the upper portion of the container 50 having the vent hole H moves upward so that the vent hole H is exposed above the upper end 104 of the cap body 100 B.
- atmospheric air is guided into the container 50 via the air paths 105 (see FIG. 8 ) of the cap body 100 B and the vent hole H of the container 50 .
- the cap device of the third embodiment further includes a stop protrusion 54 .
- the stop protrusion 54 is an annular ring which is provided around the outer circumferential surface of the additive container 50 at an intermediate position.
- the stop protrusion 54 limits an upward movement of the additive container 50 within a predetermined range. That is, the stop protrusion 54 of the container 50 is stopped by the cap body 100 A during the upward movement of the container 50 , thus limiting the upward movement of the container 50 within the predetermined range.
- the provision of the stop protrusion 54 on the container 50 is to accomplish the following operational effect. That is, at a last stage of loosening the cap cover 100 A from the cap body 100 B, the stop protrusion 54 of the container 50 is stopped by the cap body 100 A.
- the inside locking part 111 of the cap cover 100 A escapes from the outside locking part 53 of the container 50 , so that the cap cover 100 A can be completely removed from the cap body 100 B.
- the locking force to lock the inside locking part 111 of the cap cover 100 A to the outside locking part 53 of the container 50 allows the container 50 to move upward in the vertical direction by the rotation of the cap cover 100 A until the stop protrusion 54 of the container 50 is stopped by the cap body 100 A.
- the locking force to lock the inside locking part 11 of the cap cover 100 A to the outside locking part 53 of the container 50 cannot remove the stop protrusion 54 from the cap body 100 B. Therefore, when the cap cover 100 A in the above state is further rotated with the external rotating force which is stronger than the predetermined reference force, the inside locking part 111 of the cap cover 100 A forcibly escapes from the outside locking part 53 of the container 50 . Thus, the cap cover 100 A can be completely removed from the cap body 100 B.
- the cap cover 100 A is tightened to the open upper end 104 of the cap body 100 B through screw-type engagement.
- the cap cover 100 A has the inside locking part 111 on the inner circumferential surface thereof, as described above.
- the inside locking part 111 of the cap cover 100 A is locked to the outside locking part 53 of the container 50 .
- the inside locking part 111 and the outside locking part 53 constitute the locking means which locks the cap cover 100 A to the container 50 .
- cap cover 100 A When the cap cover 100 A is fully tightened to the open upper end 104 of the cap body 100 B through the screw-type engagement, the cap cover 100 A closes and seals the open upper end 104 of the cap body 100 B.
- the cap cover 100 A is fully tightened to the open upper end 104 of the cap body 100 B through the screw-type engagement, thus sealing the space 51 of the container 50 which contains both the additive and the compressed gas therein.
- an example of the additive to be contained in the container 50 can be powdered green tea or medical drugs in the form of granules or powders, while an example of the compressed gas to be injected into the container 50 can be nitrogen gas or air.
- the cap device with both the additive and the compressed gas contained in the sealed space 51 of the container 50 is shown in FIG. 6 .
- the cap cover 100 A is rotated to slightly open the cap device, as shown in FIG. 7 a .
- the flanged discharging port 52 of the container 50 is slightly spaced apart from the annular groove 222 - 2 (see FIG. 6 ) of the valve means 222 of the cap body 100 B.
- the additive is discharged from the space 51 of the container 50 into the bottle 13 through the plurality of spaces defined between the radial ribs 222 - 1 (see FIG. 6 ) and added to the bottled material to prepare the desired mixture.
- the compressed gas in the space 51 promotes the discharge of the additive.
- the slightly opened cap cover 100 A is further rotated to further open the cap device, as shown in FIG. 7 b , the upper portion of the container 50 having the vent hole H moves upward so that the vent hole H is exposed above the upper end 104 of the cap body 100 B.
- the vent hole H communicates with the atmosphere through the air paths 105 (see FIG. 8 ) which are provided on the outer circumferential surface of the upper end 104 of the cap body 100 B. Therefore, atmospheric air is guided into the space 51 of the container 50 through the air paths 105 and the vent hole H to allow the additive to be almost completely discharged from the space 51 into the bottle 13 , due to gravity.
- the cap cover 100 A in the above state is further rotated by an external rotating force which is stronger than the predetermined reference force, the inside locking part 111 of the cap cover 100 A forcibly escapes from the outside locking part 53 of the container 50 .
- the cap cover 100 A is completely removed from the cap body 100 B.
- a user can drink or use the mixture by discharging the mixture from the bottle 13 through the open upper end of the container 50 .
- the entire part of the cap device may be completely removed from the mouth 10 of the bottle 13 , as desired, by loosening the cap body 100 B from the mouth 10 of the bottle 13 .
- the cap device in the state of FIG. 6 may be completely removed from the mouth 10 of the bottle 13 by loosening the cap body 100 B from the mouth 10 of the bottle 13 .
- FIG. 9 is a sectional view of a cap device according to a fourth embodiment of the present invention, when the cap device is tightened to a mouth of a bottle.
- the cap device according to the fourth embodiment of the present invention comprises a cap body 100 B, an additive container 50 and a cap cover 100 A.

Description
- 1. Field of the Invention
- The present invention relates, in general, to caps for bottles which contain therein a variety of materials, such as drinks, liquid medicines or liquid chemicals. More particularly, the present invention relates to a cap device for such bottles, which is capable of mixing an additive contained within the cap device with a bottled material to prepare a mixture according to a simple rotating action of the cap device relative to a bottle, thus allowing a user to easily prepare the mixture just before drinking or using the mixture.
- 2. Description of the Related Art
- In the related art, most of conventional disposable bottles circulated and sold in markets each contain therein only a single kind of material, such as a drink, a liquid medicine or a liquid chemical, and are closed by caps at mouths thereof. When a user wants to add an additive to the material contained in such a capped bottle so as to prepare a mixture prior to drinking or using the mixture, the user must add the additive from a separate container to the bottled material after removing a cap from the bottle. Therefore, it is necessary for manufacturers of the additives and the bottled materials to contain such additives and materials in separate containers and bottles prior to marketing them, thus undesirably wasting natural resources due to the production of the separate containers and capped bottles. In addition, the adding of the additive from the separate container to the bottled material to mix them after removing the cap from the bottle is inconvenient to the user in that the user is forced to separately purchase and handle the additive container and the bottle.
- Furthermore, it is extremely difficult for the user to add a precise amount of the additive from the separate container to the material contained in the bottle, and thus, the user roughly measures the amount of the additive to be added to the bottled material. Therefore, in the case of mixing of an additive with a bottled drink to produce a mixed beverage, the rough measurement of the amount of the additive may result in change in taste and quality of the mixed beverage. In the case of mixing of an additive with a bottled liquid medicine or a bottled liquid chemical to produce a mixed medicine or a mixed chemical, the rough measurement of the amount of the additive may result in incomplete dissolution of effective ingredients of the additive in the medicine or the chemical and a failure of accomplishment of desired medical or chemical effects of the mixed medicine or the mixed chemical.
- Of course, when mixtures are prepared by manufacturers at factories and are marketed in a bottled state, in place of allowing users to mix additives with bottled materials to prepare mixtures just before drinking or using the mixtures, it is possible to avoid the above-described problems experienced in the mixing of the additives with the bottled materials performed by the users. However, the mixtures which are prepared by the manufacturers and marketed in the bottled state are problematic in that the effects of ingredients of the bottled mixtures may be gradually degraded as time goes by, in addition to change in colors of the mixtures. Furthermore, the bottled mixtures may generate floating matters and deposit therein with passage of time.
- In an effort to overcome the above-described problems, the inventor of the present invention proposed a cap device for bottles, which is capable of mixing an additive contained therein with a material contained in a bottle to prepare a mixture, in Korean Patent Application No. 10-2002-31470. In the above cap device disclosed in Korean Patent Application No. 10-2002-31470, a plurality of radial ribs are provided at a valve means, and are supported at outside ends thereof on an inner surface of a neck of the bottle. However, since the outside ends of the above radial ribs are formed as free ends, the radial ribs may be easily bent or deformed. Therefore, the valve means may be easily displaced in the neck of the bottle.
- Furthermore, it is necessary to separately store the additive in the cap device and the material in the bottle so that the additive is not undesirably added to the bottled material. Therefore, a sealing means for allowing the additive and the material to be separately stored in the cap device and the bottle is required.
- That is, it is necessary to accomplish an airtight or watertight sealing effect at a junction between a part of the cap device containing the additive therein and another part of the cap device which communicates with the bottle containing the material therein, thus preventing an undesired premature mixing of the additive with the bottled material and thereby preventing any physical or chemical change in the additive and the bottled material due to the undesired premature mixing of them. When the airtight or watertight sealing effect at the above junction is accomplished, the operational effect of the cap device is enhanced.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, for example, Korean Patent Application No. 10-2002-31470, and it is an aspect of the present invention to provide a cap device for bottles, which is capable of mixing an additive contained therein with a bottled material to prepare a mixture according to a simple rotating action of the cap device relative to a bottle, performed by a user, thereby allowing the user to easily prepare the mixture just before drinking or using the mixture.
- It is another aspect of the present invention to provide a cap device for bottles, in which a valve means is stably placed at a desired position in a neck of the bottle, without being undesirably displaced.
- It is a further aspect of the present invention to provide a cap device for bottles, which allows the additive and the material to be separately stored in the cap device and the bottle, respectively, such that the additive is prevented from being prematurely added to the bottled material.
- It is still another aspect of the present invention to provide a cap device for bottles, which contains a semisolid additive therein, and allows a user to mix the semisolid additive with a bottled material to prepare a mixture by simply rotating the cap device relative to a bottle just before drinking or using the mixture.
- Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

In addition, a plurality of radial ribs extending outward from an external surface of the conical valve part in radial directions, and a ring is integrated with the outside ends of the radial ribs for attachment to an inner surface of a neck of the bottle. In the alternative, the conical valve part can have an upwardly protruding shank having an external threading on its side surface corresponding to internal threading formed on the inner surface of the lower end of the funnel part.
- In an alternative embodiment, the objects of this invention can be achieved by providing a cap device for bottles, comprising: a cap body tightened to a mouth of a bottle through screw-type engagement, the cap body being opened at an upper end thereof, with a cylindrical space defined in the cap body and valve means provided in the cap body at a lower end of the cylindrical space; an additive container having a space to contain an additive therein, the additive container being received in the cylindrical space of the cap body, with a discharging port provided on a lower end of the additive container to come in close contact with the valve means of the cap body, and an upper end of the additive container being opened and projected upward from the open upper end of the cap body; a cap cover tightened to the open upper end of the cap body through screw-type engagement; and a means for locking the cap cover to the upper end of the additive container.

-
FIGS. 1 through 3 b are views of a cap device for bottles according to the first embodiment of the present invention. As shown inFIGS. 1 through 3 b, the cap device according to the first embodiment of the present invention comprises acap body 50, and acap cover 100 provided on thecap body 50 to define a space therein to contain an additive in the space. The cap device further has a valve means to allow the space defined by both thecap body 50 and thecap cover 100 to selectively communicate with an interior of abottle 13. - In a detailed description, the
cap body 50 is tightened to an externally threadedmouth 12 of thebottle 13, with afunnel part 52 integrally formed in thecap body 50 to discharge the additive into thebottle 13 through a lower end thereof. - The
cap cover 100 is provided on thecap body 50 to cover an open upper end of thecap body 50 while defining the space inside both thecap body 50 and thecap cover 100 to contain the additive in the space. - In the first embodiment of the present invention, the valve means comprises a valve member V having a
conical valve part 14 acting as a valve seat to be brought into close contact with or spaced apart from the lower end of thefunnel part 52 of thecap body 50. Theconical valve part 14 of the valve member V thus closes or opens the lower end of thefunnel part 52 according to the rotating action of thecap body 50 relative to the externally threadedmouth 12 of thebottle 13. A plurality ofradial ribs 124 extend outward from an external surface of theconical valve part 14 in radial directions such that outside ends of theradial ribs 124 are supported on the inner surface of a neck of thebottle 13. In order to allow the outside ends of theradial ribs 124 to be stably supported on the inner surface of the neck of thebottle 13, acircular ring 24 having a predetermined thickness integrally surrounds the outside ends of theradial ribs 124. - When the
cap body 50 of the cap device having the above-described construction is rotated to move up relative to the externally threadedmouth 12 of thebottle 13, the valve means separates from the lower end of thefunnel part 52, thus, opening the lower end of thefunnel part 52 of thecap body 50. Therefore, the space defined by thecap body 50 and thecap cover 100 of the cap device communicates with the interior of thebottle 13, as shown inFIGS. 3 a and 3 b. The additive is thus discharged from the space defined by thecap body 50 and thecap cover 100 into thebottle 13 to be mixed with a material contained in thebottle 13 to produce a mixture. - In the cap device of
FIGS. 1, 2 , 3 a and 3 b, a vacuum pressure may act on the surface of the additive contained in the space of the cap device, when thecap cover 100 is completely closed. In such a case, the additive cannot smoothly flow from the space of the cap device into thebottle 13, even when the space communicates with the interior of thebottle 13 by an operation of the valve means. In order to allow the additive to smoothly flow from the space into thebottle 13 in response to the communication of the space with the interior of thebottle 13, a small vent hole provided with a valve cock C to open or close the vent hole is formed at a top surface of thecap cover 100. When the valve cock C opens the vent hole, atmospheric air is introduced into the space of the cap device through the vent hole, thereby preventing any vacuum pressure from acting on the surface of the additive in the space. The additive thus smoothly flows from the space of the cap device into thebottle 13, so that the additive is easily added to the material in thebottle 13 to produce a desired mixture. -
FIGS. 4 a and 4 b are views of a valve means of the cap device, according to the second embodiment of the present invention. As shown inFIGS. 4 a and 4 b, a sealing means is provided at a junction between the valve member V and the lower end of thefunnel part 52 of thecap body 50, thus accomplishing an airtight or watertight sealing effect at the junction. - The sealing means is provided at the
conical valve part 14 of the valve member V. That is, the sealing means comprises a pluggingshank 14S of a conical valve body extending upward from avalve holder 14T of thevalve part 14. An external thread is formed around the pluggingshank 14S, such that the external thread of the pluggingshank 14S has the same pitch as an internal thread of the lower end of thefunnel part 52 of thecap body 50. In order to engage with the external thread of the pluggingshank 14S, the lower end of thefunnel part 52 is provided with anengaging part 52S on an internal surface thereof. Due to the sealing means, the desired sealing effect at the junction between the valve member V and thefunnel part 52 is accomplished. - When the
cap body 50 of the cap device is rotated to move up relative to the externally threadedmouth 12 of thebottle 13, the lower end of thefunnel part 52 is rotated to move in the same direction relative to the pluggingshank 14S. In such a case, theinternal thread 52S of thefunnel part 52 moves upward along the external thread of the pluggingshank 14S to open the lower end of thefunnel part 52. Due to the screw-type engagement of the valve member V with the lower end of thefunnel part 52, it is possible to accomplish the airtight or watertight sealing effect at the junction between the valve member V and the lower end of thefunnel part 52. -
FIGS. 5 through 8 are views of a cap device according to a third embodiment of the present invention. As shown inFIGS. 5 through 8 , the cap device according to the third embodiment of the present invention includes acap body 100B, anadditive container 50 and acap cover 100A. Thecap body 100B is tightened to an externally threadedmouth 10 of abottle 13, and defines acylindrical space 103 inside themouth 10 when thecap body 100B is tightened to themouth 10. Theadditive container 50 is received in thecylindrical space 103 of thecap body 100B and has aspace 51 therein to contain an additive in thespace 51. Thecap cover 100A is tightened to an open upper end of thecap body 100B to cover the open upper end of thecap body 100B. - In a detailed description, the
cap body 100B has a double-walled structure at a lower portion thereof, as shown inFIG. 6 . The double-walled structure of thecap body 100B includes anouter sidewall 101 and aninner sidewall 102. Theouter sidewall 101 has an internal thread on an inner circumferential surface thereof for engagement to externally threading formed on themouth 10 of thebottle 13. Thecylindrical space 103 is defined inside theinner sidewall 102 with a valve means 222 provided in theinner sidewall 102 of thecap body 100B at a lower end of thecylindrical space 103. As best seen inFIG. 6 , the valve means 222 includes a plurality of radial ribs 222-1 which extend inward from theinner sidewall 102 of thecap body 100B in radial directions at the lower end of thecylindrical space 103. The valve means 222 further includes a circular valve part integrated with inside ends of the radial ribs 222-1. The circular valve part has both an annular groove part 222-2 and a dome part 222-3. The dome part 222-3 is provided on a central area of the valve part, while the annular groove part 222-2 is provided around the dome part 222-3. The annular groove part 222-2 is inclined upward and outward on an outside surface thereof, thus providing a first inclined surface. In this embodiment, the radial ribs 222-1, the annular groove part 222-2 and the dome part 222-3 are integrated with each other into a single structure. The circular valve part having the annular groove part 222-2 and the dome part 222-3 is brought into close contact with a flanged dischargingport 52 of thecontainer 50, as will be described in detail later herein, thus executing a valve function. When the valve part of thecap body 100B opens the flanged dischargingport 52 of thecontainer 50, the additive flows from thespace 51 of thecontainer 50 into thebottle 13 through a plurality of spaces defined between the radial ribs 222-1, thus being added to a bottled material to prepare a desired mixture. - The
inner sidewall 102 of thecap body 100B is inserted into themouth 10 of thebottle 13 when thecap body 100B is tightened to themouth 10 of thebottle 13. Thecap body 100B is also opened at the upper end thereof, thus having the openupper end 104. That is, the openupper end 104 of thecap body 100B is projected upward from the remaining part of thecap body 100B, and has an external thread on the outer circumferential surface thereof, with a plurality of air paths 105 (seeFIG. 8 ) vertically provided on the externally threaded outer circumferential surface of the openupper end 104 of thecap body 100B. Theair paths 105 guide atmospheric air to a vent hole H of theadditive container 50, as will be described in detail later herein. - The
additive container 50, which is a cylindrical body, is opened at the upper and lower ends thereof, as shown inFIG. 6 . Theadditive container 50 has the flanged dischargingport 52 at a bottom wall thereof. The flanged dischargingport 52=is projected downward from the bottom wall of thecontainer 50, and is inclined upward and inward on a lower end surface thereof, thus providing a second inclined surface, as best seen inFIG. 6 . Thus, the flanged dischargingport 52 is able to be in close contact with the annular groove 222-2 of the valve means 222 of thecap body 100B when the valve means 222 is closing the dischargingport 52. In the above state, the flanged dischargingport 52 is in linear contact with the annular groove 222-2 of the valve means 222, thus providing a higher contact pressure which prevents the additive from undesirably leaking from thecontainer 50 into thebottle 13. Theadditive container 50 defines thespace 51 therein to contain the additive in thespace 51. Theadditive container 50 is also rounded along an inside corner of the bottom wall thereof, thus providing a rounded surface S on the inside corner of the bottom wall. Due to the rounded surface S, the additive is smoothly discharged from thespace 51 of thecontainer 50 into thebottle 13 through the flanged dischargingport 52 in response to an operation of the valve means 222 to open the flanged dischargingport 52. - The cap device of the third embodiment further includes a means for locking the
cap cover 100A to the upper end of theadditive container 50 while allowing thecontainer 50 to move vertically, in conjunction with a rotation of thecap cover 100A. The locking means includes anoutside locking part 53 that is provided around the outer circumferential surface of the upper end of theadditive container 50. The locking means further includes aninside locking part 111 that is provided around the inner circumferential surface of thecap cover 100A to engage with theoutside locking part 53 of thecontainer 50. Thus, theadditive container 50 is locked to thecap cover 100A by engagement of theoutside locking part 53 with theinside locking part 111, so that thecap cover 100A is removed from thecontainer 50 when thecap cover 100A is rotated with an external rotating force which is stronger than a predetermined reference force. In other words, when thecap cover 100A is rotated with an appropriate rotating force, thecontainer 50 moves vertically in conjunction with the rotation of thecap cover 100A. - The
additive container 50 has the vent hole H at a predetermined position on the upper portion of a sidewall thereof. When thecap cover 100A is fully tightened to theupper end 104 of thecap body 100B as shown inFIG. 6 , the vent hole H of thecontainer 50 is closed by theupper end 104 of thecap body 100B. However, when thecap cover 100A is loosened from theupper end 104 of thecap body 100B as shown inFIG. 7 a, the upper portion of thecontainer 50 having the vent hole H moves upward so that the vent hole H is exposed above theupper end 104 of thecap body 100B. In the above state, atmospheric air is guided into thecontainer 50 via the air paths 105 (seeFIG. 8 ) of thecap body 100B and the vent hole H of thecontainer 50. - The cap device of the third embodiment further includes a
stop protrusion 54. Thestop protrusion 54 is an annular ring which is provided around the outer circumferential surface of theadditive container 50 at an intermediate position. Thestop protrusion 54 limits an upward movement of theadditive container 50 within a predetermined range. That is, thestop protrusion 54 of thecontainer 50 is stopped by thecap body 100A during the upward movement of thecontainer 50, thus limiting the upward movement of thecontainer 50 within the predetermined range. The provision of thestop protrusion 54 on thecontainer 50 is to accomplish the following operational effect. That is, at a last stage of loosening thecap cover 100A from thecap body 100B, thestop protrusion 54 of thecontainer 50 is stopped by thecap body 100A. In the above state, when thecap cover 100A is rotated with an external rotating force which is stronger than the predetermined reference force, theinside locking part 111 of thecap cover 100A escapes from theoutside locking part 53 of thecontainer 50, so that thecap cover 100A can be completely removed from thecap body 100B. In other words, the locking force to lock theinside locking part 111 of thecap cover 100A to theoutside locking part 53 of thecontainer 50 allows thecontainer 50 to move upward in the vertical direction by the rotation of thecap cover 100A until thestop protrusion 54 of thecontainer 50 is stopped by thecap body 100A. However, once thestop protrusion 54 of thecontainer 50 is stopped by thecap body 100A, the locking force to lock the inside locking part 11 of thecap cover 100A to theoutside locking part 53 of thecontainer 50 cannot remove thestop protrusion 54 from thecap body 100B. Therefore, when thecap cover 100A in the above state is further rotated with the external rotating force which is stronger than the predetermined reference force, theinside locking part 111 of thecap cover 100A forcibly escapes from theoutside locking part 53 of thecontainer 50. Thus, thecap cover 100A can be completely removed from thecap body 100B. - As shown in
FIGS. 5 and 6 , thecap cover 100A is tightened to the openupper end 104 of thecap body 100B through screw-type engagement. Thecap cover 100A has theinside locking part 111 on the inner circumferential surface thereof, as described above. Theinside locking part 111 of thecap cover 100A is locked to theoutside locking part 53 of thecontainer 50. Theinside locking part 111 and theoutside locking part 53 constitute the locking means which locks thecap cover 100A to thecontainer 50. - When the
cap cover 100A is fully tightened to the openupper end 104 of thecap body 100B through the screw-type engagement, thecap cover 100A closes and seals the openupper end 104 of thecap body 100B. - The operation and effect of the cap device according to the third embodiment having the above-mentioned construction will be described herein below. After both a desired additive and compressed gas are injected into the
space 51 of thecontainer 50, thecap cover 100A is fully tightened to the openupper end 104 of thecap body 100B through the screw-type engagement, thus sealing thespace 51 of thecontainer 50 which contains both the additive and the compressed gas therein. In the third embodiment of the present invention, an example of the additive to be contained in thecontainer 50 can be powdered green tea or medical drugs in the form of granules or powders, while an example of the compressed gas to be injected into thecontainer 50 can be nitrogen gas or air. The cap device with both the additive and the compressed gas contained in the sealedspace 51 of thecontainer 50, is shown inFIG. 6 . - To prepare a mixture by mixing the additive with a bottled material, the
cap cover 100A is rotated to slightly open the cap device, as shown inFIG. 7 a. In the above state, the flanged dischargingport 52 of thecontainer 50 is slightly spaced apart from the annular groove 222-2 (seeFIG. 6 ) of the valve means 222 of thecap body 100B. Thus, the additive is discharged from thespace 51 of thecontainer 50 into thebottle 13 through the plurality of spaces defined between the radial ribs 222-1 (seeFIG. 6 ) and added to the bottled material to prepare the desired mixture. While the additive is discharged from thespace 51 of thecontainer 50 into thebottle 13, the compressed gas in thespace 51 promotes the discharge of the additive. - When the slightly opened
cap cover 100A is further rotated to further open the cap device, as shown inFIG. 7 b, the upper portion of thecontainer 50 having the vent hole H moves upward so that the vent hole H is exposed above theupper end 104 of thecap body 100B. Thus, the vent hole H communicates with the atmosphere through the air paths 105 (seeFIG. 8 ) which are provided on the outer circumferential surface of theupper end 104 of thecap body 100B. Therefore, atmospheric air is guided into thespace 51 of thecontainer 50 through theair paths 105 and the vent hole H to allow the additive to be almost completely discharged from thespace 51 into thebottle 13, due to gravity. - When the
cap cover 100A in the state ofFIG. 7 b is further rotated, thestop protrusion 54 that is provided on the outer circumferential surface of theadditive container 50 at the intermediate position is stopped by thecap body 100A, thus stopping the upward movement of theadditive container 50. - When the
cap cover 100A in the above state is further rotated by an external rotating force which is stronger than the predetermined reference force, theinside locking part 111 of thecap cover 100A forcibly escapes from theoutside locking part 53 of thecontainer 50. Thus, thecap cover 100A is completely removed from thecap body 100B. - After the additive from the
container 50 is mixed with the material contained in thebottle 13 to prepare the desired mixture according to the above-mentioned operation of the cap device, a user can drink or use the mixture by discharging the mixture from thebottle 13 through the open upper end of thecontainer 50. - In the above state, the entire part of the cap device may be completely removed from the
mouth 10 of thebottle 13, as desired, by loosening thecap body 100B from themouth 10 of thebottle 13. - Meanwhile, when the user desires to drink or use the bottled material without mixing the additive of the cap device with the bottled material, the cap device in the state of
FIG. 6 may be completely removed from themouth 10 of thebottle 13 by loosening thecap body 100B from themouth 10 of thebottle 13. -
FIG. 9 is a sectional view of a cap device according to a fourth embodiment of the present invention, when the cap device is tightened to a mouth of a bottle. As shown inFIG. 9 , the cap device according to the fourth embodiment of the present invention comprises acap body 100B, anadditive container 50 and acap cover 100A. Thecap body 100B is tightened to an externally threadedmouth 10 of abottle 13, and defines acylindrical space 103 inside themouth 10 when thecap body 100B is tightened to themouth 10. Theadditive container 50 is received in thecylindrical space 103 of thecap body 100B and has aspace 51 therein to contain an additive in thespace 51. Thecap cover 100A is tightened to an open upper end of thecap body 100B to cover the open upper end of thecap body 100B. - In a detailed description, the
cap body 100B has a double-walled structure at a lower portion thereof, in the same manner as that described for the third embodiment of the present invention. The double-walled structure of thecap body 100B includes anouter sidewall 101 and aninner sidewall 102. A valve means 222 is provided in theinner sidewall 102 of thecap body 100B at a lower end of thecylindrical space 103. Different from the valve means according to the third embodiment, the valve means 222 according to the fourth embodiment includes a plurality of vertical ribs 222-1 which extend downward from thecap body 100B in vertical directions at the lower end of thecylindrical space 103 of thecap body 100B. The valve means 222 further includes a circular valve part integrated with lower ends of the radial ribs 222-1. The circular valve part has a dome part 222-3 which is provided on a central area of the valve part. - The general shape of the
additive container 50 according to the fourth embodiment remains the same as that described for the third embodiment. However, theadditive container 50 according to the fourth embodiment does not have any stop projection on the circumferential outer surface thereof, and the lower end of thecontainer 50 has no bottom wall, but linearly extends downward, thus forming a wide dischargingopening 52, different from the third embodiment. The lower end surface of the dischargingopening 52 of thecontainer 50 is inclined upward and inward, thus providing an inclined surface. The dischargingopening 52 of thecontainer 50 is brought into close contact with the dome part 222-3 of the valve means 222 at the inclined surface thereof. - The operation and effect of the cap device according to the fourth embodiment having the above-mentioned construction will be described herein below.
- The
container 50 can contain therein a semisolid additive, such as ice cream, mustard sauce, thick soypaste mixed with red peppers or mayonnaise, while thebottle 13 can contain therein a desired material, such as a soda pop, a functional beverage, or soybean sauce. To mix the semisolid additive, for example, ice cream, with the bottled material, for example, soda pop, to prepare a mixture, thecap cover 100A is rotated relative to thecap body 100B. Thus, thecontainer 50 moves upward in the vertical direction. Therefore, the ice cream is discharged from thespace 51 of thecontainer 50 into thebottle 13 through a plurality of wide spaces defined between the vertical ribs 222-1, thus being added to the soda pop in thebottle 13 to prepare the desired mixture. When a user shakes thebottle 13 in the above state, it is possible to more easily and quickly mix the ice cream with the soda pop. -

Thecap body 100B defines acylindrical space 103 therein. The cap device further includes anadditive container 50 having aspace 51 to contain an additive therein. Theadditive container 50 is received in thecylindrical space 103 of thecap body 100B. The cap device further includes acylindrical control unit 100C which is assembled with the open upper end of thecap body 100B by anengaging ring 113 to rotate relative to thecap body 100B, with an internal thread provided on an inner circumferential surface of thecontrol unit 100C to be tightened to an outer circumferential surface of the upper end of theadditive container 50 through screw-type engagement. Thus, thecontrol unit 100C controls a vertical movement of theadditive container 50. The cap device further includes acap cover 100A which is tightened to the upper end of thecontrol unit 100C. In the cap device, an O-ring 112 is provided at a junction between thecap body 100B and thecontrol unit 100C to accomplish a sealing effect at the junction. The engagingring 113 extends upward from the upper end surface of thecap body 100B, and is inserted into an annular groove which is formed along the lower end of thecontrol unit 100C. Thus, thecylindrical control unit 100C rotates relative to thecap body 100B. The cap device according to the fifth embodiment further includes a valve means 222 with the same construction as that of the fourth embodiment. - As shown in
FIG. 10 , thecylindrical control unit 100C is tightened to the outer circumferential surface of the upper end of theadditive container 50 through the screw-type engagement. Thus, thecontainer 50 moves upward and downward in a vertical direction by a rotation of thecontrol unit 100C. In the same manner as that described for the fourth embodiment, thecontainer 50 functions well for containing therein and discharging a semisolid additive, such as ice cream, mustard sauce, thick soypaste mixed with red peppers or mayonnaise, while thebottle 13 contains therein a desired material, such as a soda pop, a functional beverage, or soybean sauce. -
