Abstract

A dispenser for dispensing flowable material. The dispenser comprises a resiliently deformable body encompassing a closed volume with an optional flexible pouch disposed therein to accommodate the flowable material. A discharge element having at least one discharge opening, along with at least one valve regulating flow from the closed volume or the flexible pouch and through the discharge opening is also provided. The body is configured so that a threshold amount of deformation of the body causes the flowable material to urge from the closed body through the discharge opening or the pressure increase of the closed volume acting on the flexible pouch sufficiently so that flowable material accommodated in the flexible pouch is urged therefrom through the discharge opening.

First claim

What is claimed is:

1. A dispenser for dispensing flowable material, the dispenser comprising:
a resiliently deformable body encompassing a closed volume to accommodate flowable material, wherein deformation of said body from a natural state causes a reduction of volume of said closed volume;
a discharge element having at least one discharge opening defined therein;
at least one valve regulating the flow of the flowable material through said at least one discharge opening; and,
a vent formed to communicate atmosphere outside of said body with said closed volume, wherein said vent allows for introduction of air into said closed volume to facilitate restoration of said body to said natural state after being deformed,
wherein said discharge element includes a spatula-shaped applicator having opposing faces joined by, and terminating at, a free edge;
wherein the discharge element is secured to the at least one valve; and
wherein, said body being configured so that a threshold amount of deformation of said body causes sufficient reduction of volume of said closed volume so that the flowable material is urged therefrom through said at least one discharge opening via said at least one valve.

2. The dispenser as in claim 1 , wherein the closed volume acts as a reservoir to accommodate the flow able material.

3. The dispenser as in claim 1 , wherein a flexible pouch, formed to accommodate flowable material, is disposed in said closed volume, wherein deformation of said body causes sufficient reduction of volume to increase pressure of said closed volume acting on said flexible pouch sufficiently so that flowable material accommodated in said flexible pouch is urged therefrom through said as least one discharge opening via said at least one valve.

4. The dispenser as in claim 1 , wherein said at least one valve is a one-way valve, configured to only permit flow from said flexible pouch or closed volume.

5. The dispenser as in claim 1 , wherein said at least one valve is adjustable from a closed state to an open state.

6. The dispenser as in claim 5 , wherein said at least one valve is a one-way valve configured to only permit flow from said flexible pouch.

7. The dispenser as in claim 3 , further comprising a frame disposed within said closed volume about at least portions of said flexible pouch, said frame being configured to restrict the amount of deformation of said body.

8. The dispenser as in claim 3 , wherein deformed portions of said body at said threshold amount of deformation are spaced from, so as to be out of contiguous contact with, said flexible pouch.

9. The dispenser as in claim 1 , wherein said at least discharge opening is defined in one of said faces in proximity to said free edge.

10. The dispenser as in claim 1 , wherein said vent is a one-way vent.

11. The dispenser of claim 1 , wherein said dispensing flowable material is a sunscreen lotion.

12. The dispenser of claim 1 , wherein said applicator is formed of a material that provides comfort to a user.

13. The dispenser of claim 12 , wherein said applicator is formed of silicon or thermoplastic elastomer.

14. A method for applying a flowable material to a user, comprising
applying force to the body of the dispenser of claim 1 , to urged said flowable material through the discharge opening, and
using the free edge of the applicator to apply said flowable material to the user.
