Flow-thru cosmetic applicator package
The present invention is a flow-thru cosmetic dispenser and applicator that comprises a means for controlling the flow of product from a reservoir to an applicator tip. The flow control means comprises wedge structures attached to biased hinges. The wedge structures move on the hinges in response to the removal or placement of a closure. The movement of the wedges alternately opens and pinches-off a deformable conduit in which the product flows. The invention includes means for converting any ordinary cosmetic container into a flow-thru container.
1. A flow-thru cosmetic dispenser for a flowable product comprising:
a container having a reservoir that is capable of dispensing a flowable product through a container orifice;
an applicator tip having a base and an external surface, wherein the applicator tip may comprise a bristled brush, a comb, a sponge, a powder puff, a flocked substrate or a doe-foot;
a deformable, resilient conduit that defines a lumen which, in an undeformed state, is capable of conducting product between the reservoir and the applicator tip, but which in a deformed state is hindered from conducting product;
the deformable conduit having proximal and a distal ends which define proximal and distal orifices of the lumen; and
a closure having:
an opened position, wherein the closure is not covering the applicator tip and the resilient conduit is in the undeformed state; and
a closed position, wherein the closure is covering the applicator tip and the resilient conduit is pressured into the deformed state by the closure.
2. The flow-thru cosmetic dispenser according to claim 1 wherein a portion of the deformable conduit contacts the container, forming a fluid tight seal, therebetween.
3. The flow-thru cosmetic dispenser according to claim 2 wherein the container further comprises a neck finish and the deformable conduit comprises flange that lies flat on top of the neck finish to form the fluid tight seal.
4. The flow-thru cosmetic dispenser according to claim 1 wherein at least a defined portion of the deformable conduit comprises one or more deformable, resilient materials that assume a deformed state when the closure is moved into the closed position and that substantially return to an undeformed state when the closure is moved into the opened position.
5. The flow-thru cosmetic dispenser according to claim 4 wherein the defined portion is made of natural or synthetic rubber.
6. The flow-thru cosmetic dispenser according to claim 5 wherein the synthetic rubber is a silicone elastomer.
7. The flow-thru cosmetic dispenser according to claim 6 wherein the synthetic rubber is a non-silicone elastomer chosen from the group consisting of styrene-butadiene, polybutadiene, polyisoprene, nitrile elastomers, butyl, neoprene, ethylene-propylene rubbers and urethane elastomers.
8. The flow-thru cosmetic dispenser according to claim 4 wherein the defined portion is capable of assuming a deformed state that hinders the flow of product into the applicator tip.
9. The flow-thru cosmetic dispenser according to claim 8 wherein the defined portion is capable of assuming a deformed state that cuts off the flow of product altogether.
10. The flow-thru cosmetic dispenser according to claim 4 further comprising one or more wedges capable of occupying a first position such that the wedges are not in deform deforming contact with the defined portion, and a second position such that the wedges deform the defined portion to substantially stop the flow of product through the lumen.
11. The flow-thru cosmetic dispenser according to claim 10 further comprising one or more biased hinges, one associated with each wedge.
12. The flow-thru cosmetic dispenser according to claim 11 comprising two biased hinges and two associated wedges.
13. The flow-thru cosmetic dispenser according to claim 11 wherein the one or more hinges are located in a wall of a housing that surrounds at least a portion of the deformable conduit.
14. The flow-thru cosmetic dispenser according to claim 13 wherein the housing is comprised of more than one sub-housings that fit together.
15. The flow-thru cosmetic dispenser according to claim 14 wherein the sub-housings are fit together by friction fit, snap fit, welding or mechanical band.
16. The flow-thru cosmetic dispenser according to claim 13 wherein the container further comprises a neck finish, the deformable conduit further comprises a flange and the housing is secured to the neck finish such that the flange forms an effective seal against the neck finish.
17. The flow-thru cosmetic dispenser according to claim 16 wherein the housing is secured to the neck finish by means of cooperating screw threads.
18. The flow-thru cosmetic dispenser according to claim 13 wherein the closure is capable of being secured to the housing.
19. The flow-thru cosmetic dispenser according to claim 18 wherein the one or more wedges occupy the first position when the closure is not on the housing and occupy the second position when the closure is fully seated on the housing.
20. The flow-thru cosmetic dispenser according to claim 1 wherein the applicator tip comprises a brush.
21. The flow-thru cosmetic dispenser according to claim 1 wherein the base of the applicator tip is held securely in flow communication with the distal orifice of the lumen.
22. The flow-thru cosmetic dispenser according to claim 21 wherein the base of the applicator tip is glued, in-molded, welded, crimped, snap-fitted or screw-fitted, directly or indirectly to the distal end of the deformable conduit.
23. The flow-thru cosmetic dispenser according to claim 22 wherein the base of the applicator tip is secured in flow communication with the distal orifice of the lumen by means of a ferrule, one end of which is crimped to the base of the applicator tip and the other end is inserted into the distal orifice of the lumen.
24. The flow-thru cosmetic dispenser according to claim 1 further comprising a flow tube, a proximal end of which is in flow communication with the lumen and a distal end of which is located in an interior region of the applicator tip.
25. The flow-thru cosmetic dispenser according to claim 24 wherein the distal end of the flow tube is self-closing.
