Abstract

A volatile composition dispenser comprises a volatile composition container comprising at least one volatile composition therein. A rupture element is positioned proximate to the volatile composition container. The volatile composition container comprises a cam comprising a camming surface. The camming surface is configured to move at least a portion of the rupture element toward the volatile composition container to puncture the volatile composition container and release at least a portion of the volatile composition from the volatile composition container such that the portion of the volatile composition evaporates and exits the volatile composition dispenser.

First claim

What is claimed is:

1. A volatile composition dispenser, comprising:
an outer shell;
a volatile composition container comprising at least one volatile composition therein, wherein the volatile composition container is configured to be at least partially positioned within the outer shell;
a rupturable seal sealably attached with the volatile composition container;
a rupture element disposed adjacent to the rupturable seal, the rupture element comprising an outer housing, a movable portion, and a plurality of biasing members joining the movable portion with the outer housing of the rupture element, wherein:
the movable portion comprises a puncturing member,
the movable portion has a length greater than a height,
each of the plurality of biasing members bend, flex or stretch to move the movable portion relative to the outer housing, and
the plurality of biasing members is positioned between the movable portion and outer housing, the movable portion being positioned within the outer housing;

a microporous membrane secured by the outer housing and a barrier film; and
an actuator configured to move the movable portion and puncturing member relative to the outer housing of the rupture element and toward the volatile composition container to puncture the volatile composition container and release at least a portion of the volatile composition from the volatile composition container such that the portion of the volatile composition evaporates and exits the outer shell.

2. The dispenser of claim 1 , wherein the outer shell further comprises a plurality of evaporation apertures.

3. The dispenser of claim 2 , wherein the outer shell further comprises an intensity dial element disposed adjacent to the plurality of evaporation apertures.

4. The dispenser of claim 1 , wherein the microporous membrane comprises ultra-high molecular weight polyethylene filled with silica.

5. The dispenser of claim 1 , wherein the volatile composition comprise a material selected from the group consisting of a perfume, a fragrance, an insecticide, and combinations thereof.

6. The dispenser of claim 1 , wherein the actuator comprises a mounting portion.

7. The dispenser of claim 1 , further comprising a second puncturing member spaced apart from the puncturing member.

8. The dispenser of claim 7 , wherein the puncturing member and the second puncturing member are disposed on opposing side of the movable portion.

9. The dispenser of claim 7 , further comprising third and fourth puncturing members each of which are spaced apart from the puncturing member and second puncturing member.

10. The dispenser of claim 1 , wherein the movable portion can flex, stretch and bend.

11. The dispenser of claim 1 , wherein the puncturing member has an inner face at a first angle with respect to a vertical and an outer face at a second angle with respect to the vertical, and wherein the first angle and the second angle are not equal.
