DISPENSER FOR DISPENSING FLOWABLE MATERIAL

摘要

In one aspect, a dispenser is provided herein for dispensing flowable material, such as sunscreen lotion, including a resiliently deformable body encompassing a closed volume with an optional flexible pouch disposed therein to accommodate the flowable material. A discharge element is also provided 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. 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. Advantageously, the dispenser of the subject invention allows for a generally isobaric environment to be created which acts evenly about the flexible pouch. This allows for a more even application of pressure acting against, and a more complete depletion, of the optional flexible pouch.

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 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.
