Abstract

The dose dispense closure for a squeezable container. The closure has a body cap 20 with inlet orifices 37 and a transit orifice 34 which allows composition into the body cap. A piston 80 is provided within the body cap 20. When the container is squeezed, the piston 80 is forced down, thereby expelling liquid from a control cap 40 until the piston 80 lands on the end of a duct 60 in the control cap 40 to prevent further dispensing. When the squeezing force is removed, the piston 80 returns to its start position. The piston 80 is biased towards the end wall 33 of the body cap 20 by a compression element 87 . The body cap 20 is attached directly to the container such that rotation of the body cap allows adjustment of the dosage without having to remove the body cap.

First claim

The invention claimed is:

1. A dosing dispensing closure having a user selectable feature adapted to control an amount of a fluid composition dispensed through the dosing dispensing closure, the dosing dispensing closure comprising:
a body cap having a cap top and a cylindrical section extending from the cap top, the cylindrical section having a bore, a sidewall, and an end wall, the cylindrical section also having one or more bridge sections between the sidewall and the cap top, and one or more inlet orifices intermediate the one or more bridge sections which define fluid passages adapted to permit the flow of the fluid composition therethrough, the end wall having at least one transit orifice adapted to permit the flow of the fluid composition therethrough;
a piston assembly having a piston head and a compression element biasing the piston head towards the end wall of the body cap, wherein the piston assembly is positioned within the bore of the cylindrical section and the piston head is moveable within the bore;
and a control cap which is displaceable with respect to the body cap, which includes a control cap end through which extends a fluid delivery tube, an interior sidewall having at least one full-height sidewall section and at least one reduced-height sidewall section, such that:
in at least a first relative position of the control cap with the body cap, at least a portion of the at least one full-height sidewall eclipses at least a part of the at least one inlet orifice of the body cap; and,
in at least a second relative position of the control cap with the body cap, at least a portion of the at least one full-height sidewall eclipses an area greater or lesser than the part of the at least one inlet orifice of the body cap eclipsed in the said first relative position.

2. The dosing dispensing closure according to claim 1 , wherein the body cap further includes a depending outer skirt wall which extends from an outer peripheral margin of the cap top.

3. The dosing dispensing closure according to claim 2 , wherein the depending outer skirt wall includes mating threads.

4. The dosing dispensing closure according to claim 1 , wherein the control cap further includes a plurality of control arms having an engagement means which cooperate with a part of the body cap and which are adapted to provide a slideable mechanical connection between the control cap and the body cap.

5. The dosing dispending closure according to claim 1 , wherein the control cap and the body cap form a liquid tight seal therebetween.

6. The dosing dispensing closure according to claim 1 , wherein the control cap further comprises an indicator means, and wherein the body cap includes one or more indicator legends, wherein an alignment of the indicator means with one of the indicator legends corresponds to a first volumetric dosage amount deliverable via the dosing dispensing closure, and wherein an alignment of the indicator means with a further one of the indicator legends, when present, corresponds to a different volumetric dosage amount deliverable via the dosing dispensing closure.

7. A flexible container which contains a quantity of a fluid composition having a viscosity of at least 25 cP, having mounted thereon a dosing dispensing closure according to claim 1 .

8. A method of controllably dispensing doses of a fluid composition from within a container, the method comprising the steps of:
utilizing a container which contains a quantity of a fluid composition and which further includes a dosing dispensing closure according to claim 1 , and,
dispensing dosed amounts of the fluid composition via the dispensing closure from within the container.

9. A method of controllably dispensing differing volumetric doses of a fluid composition from within a container, the method comprising the steps of:
utilizing a container which contains a quantity of a fluid composition and which further includes a dosing dispensing closure according to claim 1 ;
dispensing one or more doses of the fluid composition from the container via the dosing dispensing closure;
subsequently, realigning relative positions of the body cap and the control cap, and thereafter dispensing one or more doses of the fluid composition from the container via the dosing dispensing closure.

10. A dosing dispensing closure having a user selectable feature adapted to control an amount of a fluid composition dispensed through the dosing dispensing closure, the dosing dispensing closure comprising:
a body cap having a cap top adapted to be directly attachable to a container containing the fluid composition, and a cylindrical section extending from the cap top, the cylindrical section having a bore, a sidewall, and an end wall, the cylindrical section also having one or more bridge sections between the sidewall and the cap top, and one or more inlet orifices intermediate the one or more bridge sections which define fluid passage adapted to permit the flow of the fluid composition therethrough, the end wall having at least one transit orifice adapted to permit the flow of the fluid composition therethrough;
a piston assembly having a piston head and a compression means, wherein the piston assembly is positioned within the bore of the cylindrical section and the piston head is moveable within the bore;
and a control cap which is displaceable with respect to the body cap, which includes a control cap end through which extends a fluid delivery tube, an interior sidewall having at least one full-height sidewall section and at least one reduced-height sidewall section, such that:
in at least a first relative position of the control cap with the body cap, at least a portion of the at least one full-height sidewall eclipses at least a part of the at least one inlet orifice of the body cap; and,
in at least a second relative position of the control cap with the body cap, at least a portion of the at least one full-height sidewall eclipses an area greater or lesser than the part of the at least one inlet orifice of the body cap eclipsed in the said first relative position.

11. The dosing dispensing closure according to claim 10 , wherein the body cap further includes a depending outer skirt wall which extends from an outer peripheral margin of the cap top.

12. The dosing dispensing closure according to claim 11 , wherein the depending outer skirt wall includes mating threads.

13. The dosing dispensing closure according to claim 10 , wherein the control cap further includes a plurality of control arms having an engagement means which cooperate with a part of the body cap and which are adapted to provide a slideable mechanical connection between the control cap and the body cap.

14. The dosing dispending closure according to claim 10 , wherein the control cap and the body cap form a liquid tight seal therebetween.

15. The dosing dispensing closure according to claim 10 , wherein the control cap further comprises an indicator means, and wherein the body cap includes one or more indicator legends, wherein an alignment of the indicator means with one of the indicator legends corresponds to a first volumetric dosage amount which will be dispensed via the dosing dispensing closure, and wherein an alignment of the indicator means with a further one of the indicator legends, when present, corresponds to a different volumetric dosage amount deliverable via the dosing dispensing closure.

16. A flexible container which contains a quantity of a fluid composition having a viscosity of at least 25 cP, having mounted thereon a dosing dispensing closure according to claim 10 .
