- According to this configuration, since the valve means enables the air supply port in the cap body to be opened and closed according to the sucking operation of the tube, for example, by mounting the cap body on the mouth portion of the vessel, a liquid in the vessel can be drunk by sucking the tip end of the tube. Further, when the interior of the vessel becomes at a negative pressure according to the sucking operation of the tube, the valve means is opened to supply the outside air into the vessel, so that the liquid in the vessel can be drunk smoothly.
- To attain the above object, the present invention provides a replacement cap for a vessel, in which a cap body is mounted on a mouth portion of the vessel so as to be replaceable so that a liquid in the vessel can be drunk through a tube provided on the cap body, wherein the cap body is provided with an air supply port having cup-shaped valve means which is closed normally and is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure.
- According to this configuration, not only the liquid in the vessel can be drunk by sucking the tip end of the tube but also the liquid in the vessel can be drunk smoothly because the valve means is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure.
- Also, since the air supply port is normally closed by the valve means, even if the vessel is laid down or turned down mistakenly, the liquid in the vessel does not leak from the suction port, so that there is no fear that the leaking liquid soils clothes etc.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the valve means is composed of a valve element which has elasticity and is provided with an air hole in the top portion thereof and a protrusion which opens and closes the air hole.
- According to this configuration, even if the valve element opens and closes repeatedly, the sealing function of the valve element does not decrease. Therefore, the replacement cap can be used for a long period of time, and can be provided at a low cost because the valve means has a simple construction.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the tube is composed of an internal tube and an external tube, and the internal and external tubes are connected to tube connecting portions projectingly provided on the inside and outside of the cap body, respectively.
- According to this configuration, there is no need for forming a through hole for inserting the tube in the cap body, so that there is no fear that the liquid in the vessel leaks from the through hole.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the length of the internal tube is set so that the tip end of the internal tube reaches a position near the inside bottom portion of the vessel, and a sucking member installed at the tip end of the external tube consists of a nipple.
- According to this configuration, the liquid in the vessel can be drunk without leaving the liquid, and also the liquid in the vessel that is contained in a rucksack etc. can be drunk by increasing the length of the external tube. Further, even a patient etc. who are in a bedridden state can drink the liquid in the vessel through the external tube without raising himself/herself. Therefore, the replacement cap for a vessel in accordance with the present invention can contribute greatly to nursing of a sick person.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, a nipple is installed at the tip end of the external tube.
- According to this configuration, by mounting the cap body on a nursing bottle, the replacement cap can be used to feed milk to an infant. Also, since the infant takes down less air due to the internal tube reaching the inside bottom portion of the vessel, there is scarcely a need for belching after feeding milk.

The whole of thecap body 2 is integrally formed of a synthetic resin, and ascrew portion 2a which is threadedly engaged with thescrew portion 1b formed on the outer peripheral surface of themouth portion 1a is formed on the inner peripheral surface of thecap body 2. - In the upper face of the
cap body 2, asuction port 3 and anair supply port 4 are formed at positions, which are opposed to each other on the opposite sides of the center of thecap body 2. - The
suction port 3 is composed of an internaltube connecting portion 3a projectingly provided on the lower face of thecap body 2 in such a manner as to be substantially vertical and an externaltube connecting portion 3b projectingly provided on the upper face of thecap body 2 in such a manner as to be substantially horizontal, and aflow path 3c is formed substantially into an L shape in the internal and externaltube connecting portions - A
tube 5 for sucking a drinking liquid contained in thevessel 1 includes aninternal tube 5a one end side of which is fitted on the internaltube connecting portion 3a and the other end side of which reaches a position near the inside bottom portion of thevessel 1 and anexternal tube 5b one end side of which is fitted on the externaltube connecting portion 3b and the other end side of which is connected with a suckingmember 6, and is formed of a soft tube such as a silicone tube. Theexternal tube 5b is configured so that the length thereof can be changed arbitrarily in such a manner that the liquid in thevessel 1 can be drunk even in a state in which thevessel 1 is contained in, for example, a rucksack. - The sucking
member 6 connected to the other end of theexternal tube 5b is composed of amouthpiece 6a formed of a soft material such as silicone and atube connecting element 6b. - The
mouthpiece 6a is projectingly provided with alip portion 6c, which is formed into a substantially elliptical shape, in the tip end portion thereof as shown in FIG. 4. Thelip portion 6c is put into a mouth and pressed vertically, by which aslit 6d formed in front is opened so that the liquid in thevessel 1 can be sucked. Acylindrical portion 6f, which is provided on one end side of thetube connecting element 6b, is fitted in acylindrical portion 6e, which is projectingly provided on the back face side of themouthpiece 6a, in a liquid-tight manner. - The other end of the
external tube 5b is fitted on a connectingportion 6g projectingly provided on the other end side of thetube connecting element 6b. - If a
cover 8 which can be opened and closed freely as shown in FIG. 6 is installed on theexternal tube 5b in advance, the suckingmember 6 is housed in thecover 8 when the liquid in thevessel 1 is not drunk, by which dust, various bacteria, etc. are prevented from adhering to the suckingmember 6. Therefore, this configuration is hygienic. - The
air supply port 4 provided in thecap body 2 has anair supply hole 4a penetrating the upper and lower faces of thecap body 2. In an opening on the upper face side of theair supply hole 4a, across-shaped rib 4b is provided to prevent foreign matters from entering. - In an opening on the lower face side of the
air supply hole 4a, acylindrical projecting portion 4c is projectingly provided at the periphery of the opening, and valve means 10 is housed in the projectingportion 4c. - The valve means 10 is composed of a thin film-
shaped valve element 10a formed of silicone rubber and a needle-shaped protrusion 10b projectingly provided on the lower face of thecross-shaped rib 4b. - The
valve element 10a is formed into a cup shape whose upper face is closed as shown in FIG. 5. The top portion of thevalve element 10a is formed with anair hole 10c which is opened and closed by theprotrusion 10b, and aflange portion 10d projectingly provided in the lower end portion of thevalve element 10a is held between the lower end of the projectingportion 4c and apressing cap 11 mounted at the outer periphery of the projectingportion 4c. In the bottom face of thepressing cap 11 is formed anopening 11a having a diameter approximately equal to the inside diameter of the projectingportion 4c. - Next, the operation of the replacement cap constructed as described above will be explained.
- In the case where the replacement cap is used by mounting the
cap body 2 on themouth portion 1a of thevessel 1 such as a commercially available PET bottle, an existing cap (not shown) having been installed on themouth portion 1a of thevessel 1 is first removed, and thecap body 2 is mounted on themouth portion 1a. - At this time, the length of the
internal tube 5a having been installed in advance on the lower face of thecap body 2 is made a length such that the tip end of theinternal tube 5a reaches the inside bottom portion of thevessel 1, whereby the liquid in thevessel 1 can be drunk without leaving the liquid. In the case where thevessel 1 is a nursing bottle for feeding milk, an infant does not take down air together with the liquid, so that there is scarcely a need for belching after feeding milk. - Also, the
external tube 5b installed on the upper face side of thecap body 2 can have a length suitable for an environment in which the liquid in thevessel 1 is drunk. When the liquid in thevessel 1 is drunk, the suckingmember 6 is taken out of thecover 8 and themouthpiece 6a is held in the mouth, and the liquid is sucked while themouthpiece 6a is pressed vertically with the lips. - Thereby, the liquid in the
vessel 1 can be drunk, and also as the interior of thevessel 1 becomes at a negative pressure, thevalve element 10a having been in a position indicated by an imaginary line in FIG. 7 is elastically deformed to a position indicated by a solid line so that theair hole 10c having been closed by theprotrusion 10b is opened and hence the outside air is supplied into thevessel 1 through theair hole 10c, by which the liquid in thevessel 1 can be drunk smoothly. - When the drinking of the liquid in the
vessel 1 is stopped, thevalve element 10a returns to the position indicated by the imaginary line in FIG. 7, and hence theair hole 10c in thevalve element 10a is closed by theprotrusion 10b. Therefore, even if thevessel 1 is laid down or turned down mistakenly, the liquid in thevessel 1 does not leak from thesuction port 4. - In the above-described embodiment, explanation has been given of the case where the replacement cap is used by mounting the
cap body 2 on themouth portion 1a of thevessel 1 such as a PET bottle. However, the replacement cap can also be used for feeding milk by installing anipple 12 as shown in FIG. 8 at the tip end of theexternal tube 5b and mounting thecap body 2 on the mouth portion of a nursing bottle. - Although the
cap body 2 is mounted on themouth portion 1a of thevessel 1 such as a PET bottle in the above-described embodiment, thevessel 1 of PET bottle sometimes has themouth portion 1a with a different diameter. In this case, it is a matter of course that the same effect can be achieved by providing an adapter fit for that diameter and connecting thecap body 2 to themouth portion 1a via this adapter. - Also, although the
tube 5 is formed of a silicone material in the above-described embodiment, thetube 5 may be formed of a soft elastomer or the like. - Further, in the above-described embodiment, the
external tube 5b may be too long and be a hindrance. In such a case, the end portion of theexternal tube 5b is fixed on the clothing or the like with a fixing member such as a clip, by which theexternal tube 5b can be prevented from being a hindrance. - As described above in detail, according to the present invention, the cap body of the replacement cap, which is constructed so that the liquid in the vessel can be drunk through the tube, is provided with the air supply port having the valve means which is closed normally and is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure. Therefore, not only the liquid in the vessel can be drunk by sucking the tip end of the tube but also the liquid in the vessel can be drunk smoothly because the valve means is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure. In addition, since the air supply port is normally closed by the valve means, even if the'vessel is laid down or turned down mistakenly, the liquid in the vessel does not leak, so that there is no fear that the leaking liquid soils clothes etc.
- Also, since the valve means is composed of the valve element that has elasticity and is provided with the air hole in the top portion thereof and the protrusion that opens and closes the air hole, even if the valve element opens and closes repeatedly, the sealing function of the valve element does not decrease. Therefore, the replacement cap can be used for a long period of time, and can be provided at a low cost because the valve means has a simple construction. Also, since the tube is composed of the internal tube and the external tube, and the internal and external tubes are connected to the tube connecting portions projectingly provided on the inside and outside of the cap body, respectively, there is no need for forming a through hole. Therefore, there is no fear that the liquid in the vessel leaks out through the through hole.
- Further, since the length of the internal tube is set so that the tip end of the internal tube reaches a position near the inside bottom portion of the vessel, and the sucking member is installed at the tip end of the external tube, the liquid in the vessel can be drunk without leaving the liquid, and also the liquid in the vessel that is contained in a rucksack etc. can be drunk by increasing the length of the external tube.
- Moreover, if a nipple is installed at the tip end of the external tube, by mounting the cap body on a nursing bottle, the replacement cap can be used to feed milk to an infant. Also, since the infant takes down less air due to the internal tube reaching the inside bottom portion of the vessel, there is scarcely a need for belching after feeding milk.
