Description
~ 3 2 4 3 L~ eJ
The invention relates generally to a dispensing closure cap and more particularly to an adiustable metering closure cap which has more than one dispen~ing position.
Dispensin~ containers have several typeæ of closures, but generally these closures have either an open or a closed position. In the open or dispensing position, the contents of the container can be dlspensed at a rate designed by the open position structure. In the closed position, the contents are sealed in the container and cannot be dispensed therefrom.
The dispensing closure can be of the push-pull type or threaded screw type, but generally only have two positions, either fully open or closed. Some attempts have been made at dispensing disclosures having more than one dispensing position or which have a varlety of metered dispensing openings.
Typically, these structures are complex or fragile or both.
It would be desirable to provide a dispenslng closure cap which has more than one dispensing position, is formed with a minimum of parts and is sturdy in construction.
The above and other disadvantages of prior art dispensing closure caps are overcome in accordance with the present invention by providing a closure cap for dispensing contentQ of a container, comprising: a central upstanding post having a top surface and a substantially cylindrical imperforate peripheral wall, said wall including at least one slot formed along a ~ubfitantial length of an upper portion thereof opening to said post top sur~ace for meterlng the contents to be dispensed; and a cap body reciprocally mounted on said central --` 132~3~
post and having an in~ler periphery which cooperates with said post peripheral wall and said slot to provide a closure position with said slot being above said cap body inner periphery and at least two dispensing positions for dispensing the contents at least at two different rates as said cap body is moved on said post away from said closure position, one of said dispensing positions provided by said cap body inner periphery clearing said top surface of said post and said second dispensing pos$tion provided between said cap body inner periphery and said slot.
From another aspect, the present invention also provides a closure cap for dispensing contents of a container, comprising:
a central post having a top surface and a substantially cylindrical imperforate peripheral wall, said cylindrical imperforate peripheral wall including a plurality of reduced wall peripheral portions formed in said wall opening to said post top surface for metering the contents to be dispensed; and a cap body reciprocally mounted on said central post and having an inner periphery which cooperates with said post peripheral wall to form a variable opening between said cap body inner periphery and said post peripheral wall and to provide a closure position below said reduced wall peripheral portion and a plurality of dispensing positions for dispensing the contents at a plurality of different rates as said cap body ls moved on said post away from said closure position.
The preferred embodiments of this invention will now be described by way of example, with reference to the drawin~s accompanying this specification in which:

respectively ars side sectional views of further embodiments of the dispensing post of the invention, respectively in the closed and the open positions.
Referring to Figs. 1 and 2, one embodiment of an ad-~ustable metering closure cap of the invention is designated generally by the reference numeral 10~ The closure cap in-cludes an outer cap body 12 and an inner metering post 14.
An outer side wall 16 of the cap body 12 is formed for easy manipulation by the user and preferably includes a plurality of outstanding ribs 18 to be grasped by the user.
The cap body 12 is moved along a portion of the length of the post 14 from a closed position illustrated in Figs. 1 and 2 to a fully opened position 20, indicated by dashed lines in Fig. 2. The cap body 12 includes an inner periphery 22, here circular which mates with an outer periphery 24 of the post 14.
The post 14 includes one or more slots 26 of the same or variable lengths (not illustrated) to provide metered dispensing openings as the cap body 14 is moved to the fully open position 20. In the clpsed position (Fig. 1), the cap body periphery 22 abuts aga~nst the post periphery 24 below ~ 3 ~
the slots 26 to prevent the contents of the container (not illustrated) from being dispensed. As the cap body 12 is moved along the length of the post 14, first the slots 26 are opened to dispense the product therefrom. Then, in the fully open position 20, the cap body periphery 22 clears the top 28 of the post 14 to provide a second dispensing posi-tion with an increased dispensing flow rate.
The cap body 12 can be mounted for a push-pull opera-tion or can be mounted on one or more threads 30 for a screw type operation or a combination of both, as illustrated in Figs. 5A and 5B. The post 14, as best illustrated in Figs.
3 and 4, includes a base portion 32 having a shoulder 34 against which a bottom edge 36 of the cap body 12 abuts in the fully closed position. The base 32 includes a plurality of threads 38 for securing the post 14 and hence the closure 10 onto a dispensing container, not illustrated. The threads 30 are formed on an outer periphery wall portion 40 - inset from the base 32 above the shoulder 34.
A second outer periphery wall portion 42 is formed ~0 above the wall 40 and joined thereto by a shoulder 44. The periphery wall 42 is inset from the periphsry wall 40 and includes an outer flange 46 at an upper end thereof. The flange 46 and hence the wall 42 are ~oined to the periphery 24 by a shoulder 48.
The cooperative operation of the cap body 12 and the metering post 14 are best illustrated in Figs. 5A and 5B.
The cap body 12 and the post 14 cooperate to provide both a screw type and a push-pull type operat~on to provide the different dispensing openings. As illustrated in Fig. 5A, the cap body bottom edge 36 abuts the shoulder 34 when tha closure 10 is in the closed position. Also, the cap body periphery 22 abuts the post periphery 24 below the openings of the slots 26 to prevent dispensing of the contents of the container.
A first dispensing position 50 is illustrated in dashed lines in Fig. 5B. In this position, the periphery 22 is above the bottom of the openings of the slots 25, enabling 3~ '3 the contents of the container, for example, a s~ueeze type container, to be dispensed therethrough. Although not il-lustrated, the slots 26 can have varying lengths which could provide multiple dispensing openings for different flow rates. The cap body 12 is moved to the first dispensing opening by unscrewing the cap body 12 on the threads 30, the cap body cooperating therewith by projections or thread tracks 52 formed on an inner wall 54 thereof.
The cap body 12 includes an annular ring 56, which bears against the wall 42 to aid in preventing the contents frcm leaking down onto the shoulder 34 and to provide a stop for the fully open position 20. In the fully open position 20, the ring 56 bears against the flange 46 to prevent removal of the cap body 12 from the post 14. The primary seal against leakage is provided by an inner wall 58 of the cap body 12, which abuts the flange 46 in all positions.
As clearly illustrated in Fig. 5B, the cap body 12 and the post 14 have a first screw type operation until the tracks 52 pass out of the threads 50. Thereafter, the cap body 12 and the post 14 operate in a push-pull mode with the ring 56 and the flange 46 providing the upper fully open stop for the cap body 12. In the fully open position 20, the periphery 22 clears the periphery 24 and the contents flow through a second larger dispensing opening. The top 28 of the post 14 can include a shoulder 60 to aid in the periphery 22 passing downwardly onto the post 14. The shoulder 48 can be a solid portion with holes therein or can be formed in a plurality of ribs 62, having a plurality of dlspensing openings 64 formed between the periphery 24 and the wall 44. The contents flow through the openings 64 to be dispensed from the container.
A second embodiment of a closure cap of the invsntion is indicated generally by the reference numeral 66 in Fig.
6, with parts which are substantially unchanged having the same numerals as previously utilized. The closure 66 is shown in solid lines in tha closed position and in dashed lines in the fully open position 20. The closure 66 in-3 ~ ~ `
cludes a cap body 68 and a metering post 70, which again op-erate in a push-pull and a screw type mode. The post 70 in-cludes a lower peripheral wall 72 having an annular ring or 1ange 7~ at the upper end thereof. The post 70 further in-cludes a second peripheral wall 76 formed above the flange 74 and which includes one or more of the threads 30 formed thereon.
The cap body 68 includes a lower annular ring 78 on an inner wall 80 thereof. The ring 78 cooperates with the ~lange 74 to provide the upper, fully open, stop position for the closure 66. The cap body 68 includes a screw track 82 on an inner wall 84, which cooperates with the threads 30 for the first part of the dispensing operation. The track 82 clears the threads 30 to operate in the push-pull mode to provide the second fully open dispensing position.
A solely push-pull operating embodiment of the closure cap of the invention is illustrted in Fig. 7 and is general-ly designated by the reference numeral 84. The closure 84 includes a cap body 86 and a metering post 88. The post 88 includes a first peripheral wall 90 with a shoulder 92 formed on the top end thereof. A second peripheral wall 94 ad~oins the shoulder 92 and has a flange 96 formed at an up-per end thereof. The cap body 86 includes a first inner wall 98, which cooperates slidingly with the wall 90. The cap body 86 includes an annular stop ring 100 formed above the wall 98 and which slid~ngly cooperates with the wall 94.
The ring 100 forms a stop against the flange 96 for the open position and against the shoulder 92 in the closed position.
The closure cap 84 operates only in the push-pull mode, but otherwise operates in a fashion similar to the closures 10 and 66.
Figs. 8A and 8B illustrate respectively, the closed position and two open dispensing positions for a closure cap 102. The closure 102 can be designed as a push-pull, as il-lustrated, or screw type or combination as above described.
The closure 102 includes a cap body 104 and a metering post 106. The post 106 includes a peripheral wall 108 having an ~,.?~%~3L~ 3 annular flange 110 and 112 on each end thereof. The flanges 110 and 112 cooperate with a ring 114 formed on an inner wall 116 of the cap body 104 to form the upper and lower stop positions. The wall 116 also cooperates with the flange 112 to prevent leakage of the contents down along the post 106. The shoulder 48 again contains the dispensing openings (not illustrated).
The top of the post 106 includes the outer periphery 24 which cooperates as before with the periphery 22 to close the closure 102. However, the post 106 does not include the slots 26, but instead includes a plurality of stepped peripheral walls 118~ As the periphery 22 of the cap body 104 is raised, the dispensing opening increases until the fully open position 20 is reached. In this operation, the number of dispensing positions and hence dispensing flow rates is virtually unlimited.
Referring to Figs. 9A and 9B, another embodiment of closure cap is illustrated generally indicated by the reference numeral 120. The closure 120 includes the same cap body 104, which operates substantially the same as the closure 102. A metering post 122 is the same as the post 106 with the exception of the metering stepped walls 118 of the post 106. The post 122 includes a conical shaped top portion 124 which provides an infinite number of dispensing positions as the periphery 22 is moved relative thereto be-tween the closed and the fully open position 20.
In a li~e manner, a further embodiment of closure cap is best illustrated in Figs. lOA and lOB generally indicated by the reference numeral 126. The closure 126 includes a metering post 128 which again is different from the post 106 by the design of the dispensing openings. The post 128 in-cludes a plurality of wedge of V-shaped slots 130. The slots 130 open to the top of the post 128 so that the dis-pensing openings increase in size as the cap body 104 is moved toward th0 fully open position 20.
Modifications and variations of the present invention are possibl0 in light of the above teachings. The fully open position 20 can be adjusted so that there is a larger or smaller dispensing opening in the fully open position depending on the type of contents to be dispensed. Further, although not illustrated, the various types of openings could be combined, for example, the slots 26 and the slots 130 with various alignment. Also, the conical post 124 could include the slots 26 or 130 or both. The shape of the slots 26, 130 also can be varied as well as the shape of the cone 124 and the number and shape of the steps 118. The closures preferably are formed by molding from a strong resilient plastic, such as polypropylene. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
The invention relates generally to a dispensing closure cap and more particularly to an adiustable metering closure cap which has more than one dispen~ing position.
Dispensin~ containers have several typeæ of closures, but generally these closures have either an open or a closed position. In the open or dispensing position, the contents of the container can be dlspensed at a rate designed by the open position structure. In the closed position, the contents are sealed in the container and cannot be dispensed therefrom.
The dispensing closure can be of the push-pull type or threaded screw type, but generally only have two positions, either fully open or closed. Some attempts have been made at dispensing disclosures having more than one dispensing position or which have a varlety of metered dispensing openings.
Typically, these structures are complex or fragile or both.
It would be desirable to provide a dispenslng closure cap which has more than one dispensing position, is formed with a minimum of parts and is sturdy in construction.
The above and other disadvantages of prior art dispensing closure caps are overcome in accordance with the present invention by providing a closure cap for dispensing contentQ of a container, comprising: a central upstanding post having a top surface and a substantially cylindrical imperforate peripheral wall, said wall including at least one slot formed along a ~ubfitantial length of an upper portion thereof opening to said post top sur~ace for meterlng the contents to be dispensed; and a cap body reciprocally mounted on said central --` 132~3~
post and having an in~ler periphery which cooperates with said post peripheral wall and said slot to provide a closure position with said slot being above said cap body inner periphery and at least two dispensing positions for dispensing the contents at least at two different rates as said cap body is moved on said post away from said closure position, one of said dispensing positions provided by said cap body inner periphery clearing said top surface of said post and said second dispensing pos$tion provided between said cap body inner periphery and said slot.
From another aspect, the present invention also provides a closure cap for dispensing contents of a container, comprising:

respectively ars side sectional views of further embodiments of the dispensing post of the invention, respectively in the closed and the open positions.
Referring to Figs. 1 and 2, one embodiment of an ad-~ustable metering closure cap of the invention is designated generally by the reference numeral 10~ The closure cap in-cludes an outer cap body 12 and an inner metering post 14.
An outer side wall 16 of the cap body 12 is formed for easy manipulation by the user and preferably includes a plurality of outstanding ribs 18 to be grasped by the user.
The cap body 12 is moved along a portion of the length of the post 14 from a closed position illustrated in Figs. 1 and 2 to a fully opened position 20, indicated by dashed lines in Fig. 2. The cap body 12 includes an inner periphery 22, here circular which mates with an outer periphery 24 of the post 14.
The post 14 includes one or more slots 26 of the same or variable lengths (not illustrated) to provide metered dispensing openings as the cap body 14 is moved to the fully open position 20. In the clpsed position (Fig. 1), the cap body periphery 22 abuts aga~nst the post periphery 24 below ~ 3 ~
the slots 26 to prevent the contents of the container (not illustrated) from being dispensed. As the cap body 12 is moved along the length of the post 14, first the slots 26 are opened to dispense the product therefrom. Then, in the fully open position 20, the cap body periphery 22 clears the top 28 of the post 14 to provide a second dispensing posi-tion with an increased dispensing flow rate.
The cap body 12 can be mounted for a push-pull opera-tion or can be mounted on one or more threads 30 for a screw type operation or a combination of both, as illustrated in Figs. 5A and 5B. The post 14, as best illustrated in Figs.
3 and 4, includes a base portion 32 having a shoulder 34 against which a bottom edge 36 of the cap body 12 abuts in the fully closed position. The base 32 includes a plurality of threads 38 for securing the post 14 and hence the closure 10 onto a dispensing container, not illustrated. The threads 30 are formed on an outer periphery wall portion 40 - inset from the base 32 above the shoulder 34.
A second outer periphery wall portion 42 is formed ~0 above the wall 40 and joined thereto by a shoulder 44. The periphery wall 42 is inset from the periphsry wall 40 and includes an outer flange 46 at an upper end thereof. The flange 46 and hence the wall 42 are ~oined to the periphery 24 by a shoulder 48.
The cooperative operation of the cap body 12 and the metering post 14 are best illustrated in Figs. 5A and 5B.
The cap body 12 and the post 14 cooperate to provide both a screw type and a push-pull type operat~on to provide the different dispensing openings. As illustrated in Fig. 5A, the cap body bottom edge 36 abuts the shoulder 34 when tha closure 10 is in the closed position. Also, the cap body periphery 22 abuts the post periphery 24 below the openings of the slots 26 to prevent dispensing of the contents of the container.
A first dispensing position 50 is illustrated in dashed lines in Fig. 5B. In this position, the periphery 22 is above the bottom of the openings of the slots 25, enabling 3~ '3 the contents of the container, for example, a s~ueeze type container, to be dispensed therethrough. Although not il-lustrated, the slots 26 can have varying lengths which could provide multiple dispensing openings for different flow rates. The cap body 12 is moved to the first dispensing opening by unscrewing the cap body 12 on the threads 30, the cap body cooperating therewith by projections or thread tracks 52 formed on an inner wall 54 thereof.
The cap body 12 includes an annular ring 56, which bears against the wall 42 to aid in preventing the contents frcm leaking down onto the shoulder 34 and to provide a stop for the fully open position 20. In the fully open position 20, the ring 56 bears against the flange 46 to prevent removal of the cap body 12 from the post 14. The primary seal against leakage is provided by an inner wall 58 of the cap body 12, which abuts the flange 46 in all positions.
As clearly illustrated in Fig. 5B, the cap body 12 and the post 14 have a first screw type operation until the tracks 52 pass out of the threads 50. Thereafter, the cap body 12 and the post 14 operate in a push-pull mode with the ring 56 and the flange 46 providing the upper fully open stop for the cap body 12. In the fully open position 20, the periphery 22 clears the periphery 24 and the contents flow through a second larger dispensing opening. The top 28 of the post 14 can include a shoulder 60 to aid in the periphery 22 passing downwardly onto the post 14. The shoulder 48 can be a solid portion with holes therein or can be formed in a plurality of ribs 62, having a plurality of dlspensing openings 64 formed between the periphery 24 and the wall 44. The contents flow through the openings 64 to be dispensed from the container.
A second embodiment of a closure cap of the invsntion is indicated generally by the reference numeral 66 in Fig.
6, with parts which are substantially unchanged having the same numerals as previously utilized. The closure 66 is shown in solid lines in tha closed position and in dashed lines in the fully open position 20. The closure 66 in-3 ~ ~ `
cludes a cap body 68 and a metering post 70, which again op-erate in a push-pull and a screw type mode. The post 70 in-cludes a lower peripheral wall 72 having an annular ring or 1ange 7~ at the upper end thereof. The post 70 further in-cludes a second peripheral wall 76 formed above the flange 74 and which includes one or more of the threads 30 formed thereon.
The cap body 68 includes a lower annular ring 78 on an inner wall 80 thereof. The ring 78 cooperates with the ~lange 74 to provide the upper, fully open, stop position for the closure 66. The cap body 68 includes a screw track 82 on an inner wall 84, which cooperates with the threads 30 for the first part of the dispensing operation. The track 82 clears the threads 30 to operate in the push-pull mode to provide the second fully open dispensing position.
A solely push-pull operating embodiment of the closure cap of the invention is illustrted in Fig. 7 and is general-ly designated by the reference numeral 84. The closure 84 includes a cap body 86 and a metering post 88. The post 88 includes a first peripheral wall 90 with a shoulder 92 formed on the top end thereof. A second peripheral wall 94 ad~oins the shoulder 92 and has a flange 96 formed at an up-per end thereof. The cap body 86 includes a first inner wall 98, which cooperates slidingly with the wall 90. The cap body 86 includes an annular stop ring 100 formed above the wall 98 and which slid~ngly cooperates with the wall 94.
The ring 100 forms a stop against the flange 96 for the open position and against the shoulder 92 in the closed position.
The closure cap 84 operates only in the push-pull mode, but otherwise operates in a fashion similar to the closures 10 and 66.
Figs. 8A and 8B illustrate respectively, the closed position and two open dispensing positions for a closure cap 102. The closure 102 can be designed as a push-pull, as il-lustrated, or screw type or combination as above described.
The closure 102 includes a cap body 104 and a metering post 106. The post 106 includes a peripheral wall 108 having an ~,.?~%~3L~ 3 annular flange 110 and 112 on each end thereof. The flanges 110 and 112 cooperate with a ring 114 formed on an inner wall 116 of the cap body 104 to form the upper and lower stop positions. The wall 116 also cooperates with the flange 112 to prevent leakage of the contents down along the post 106. The shoulder 48 again contains the dispensing openings (not illustrated).
The top of the post 106 includes the outer periphery 24 which cooperates as before with the periphery 22 to close the closure 102. However, the post 106 does not include the slots 26, but instead includes a plurality of stepped peripheral walls 118~ As the periphery 22 of the cap body 104 is raised, the dispensing opening increases until the fully open position 20 is reached. In this operation, the number of dispensing positions and hence dispensing flow rates is virtually unlimited.
Referring to Figs. 9A and 9B, another embodiment of closure cap is illustrated generally indicated by the reference numeral 120. The closure 120 includes the same cap body 104, which operates substantially the same as the closure 102. A metering post 122 is the same as the post 106 with the exception of the metering stepped walls 118 of the post 106. The post 122 includes a conical shaped top portion 124 which provides an infinite number of dispensing positions as the periphery 22 is moved relative thereto be-tween the closed and the fully open position 20.
In a li~e manner, a further embodiment of closure cap is best illustrated in Figs. lOA and lOB generally indicated by the reference numeral 126. The closure 126 includes a metering post 128 which again is different from the post 106 by the design of the dispensing openings. The post 128 in-cludes a plurality of wedge of V-shaped slots 130. The slots 130 open to the top of the post 128 so that the dis-pensing openings increase in size as the cap body 104 is moved toward th0 fully open position 20.
Modifications and variations of the present invention are possibl0 in light of the above teachings. The fully open position 20 can be adjusted so that there is a larger or smaller dispensing opening in the fully open position depending on the type of contents to be dispensed. Further, although not illustrated, the various types of openings could be combined, for example, the slots 26 and the slots 130 with various alignment. Also, the conical post 124 could include the slots 26 or 130 or both. The shape of the slots 26, 130 also can be varied as well as the shape of the cone 124 and the number and shape of the steps 118. The closures preferably are formed by molding from a strong resilient plastic, such as polypropylene. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
