Abstract

Methods and apparatus are provided for activating a volatile dispensing device. The apparatus includes a puncturing mechanism formed between a first portion and a second portion of an activation arm and the puncturing mechanism being shaped to move laterally to puncture a volatile container as a compressive load is applied to the activation arm through the first and second portions.

First claim

What is claimed is:

1. A device for activating a volatile dispensing device, comprising:
a puncturing mechanism formed between a first portion and a second portion of an activation arm; and
said puncturing mechanism being shaped to move laterally to puncture a volatile container as a compressive load is applied to said activation arm through said first and second portions, wherein said second portion is positioned within a reservoir between a volatile container and a base portion of a wick, wherein a volatile composition from said volatile container is released into said reservoir upon activation of said puncturing mechanism.

2. A system for activating a volatile dispensing device, comprising:
a base end of a wick and a volatile container of a volatile composition positioned within a reservoir covered with an outer housing;
a puncturing mechanism formed between a first portion and a second portion of an activation arm where said first portion is spaced apart from an outer housing with a removable spacer and said second portion is in contact with a floor of said reservoir;
wherein said puncturing mechanism is shaped to move laterally to puncture said volatile container as a compressive load is applied to said activation arm through said first and second portions when said removable spacer is removed.

3. The system of claim 2 , wherein said puncturing mechanism comprises multiple living hinges that collectively bend under a compressive load applied to said activation arm such that at least one rigid section between said multiple living hinges is pivoted towards said volatile container.

4. The system of claim 2 , wherein said puncturing mechanism comprises a free end of said activation arm that is positioned to slide laterally as said first and second portions are compressed together.

5. The system of claim 2 , wherein said volatile container comprises a section proximate said puncturing mechanism that is made of a flexible membrane.

6. The system of claim 2 , wherein said outer housing comprises a shelf to hold said reservoir within an inner chamber of said outer housing, said shelf being spaced apart from an interior protrusion protruding into said inner chamber such that when said reservoir is held with said shelf said interior protrusion causes said compressive load to said activation mechanism.

7. The system of claim 2 , wherein said first portion of said activation arm comprises two pieces that form a gap wide enough to fit around a portion of said wick.

8. The system of claim 2 , wherein said outer housing comprises at least one ventilation opening to vent airborne chemicals evaporated from said volatile composition from off of a surface area in communication with said wick.
