Abstract
A volatile dispenser for use in a volatile dispensing system is provided. The volatile dispenser includes a blister with a surface having at least one flexible portion, a permeable membrane sealable to the surface and configured to form a sealed reservoir with the blister, and a volatile material contained within the sealed reservoir. Diffusion of the volatile material through the permeable membrane generates a pressure differential between the sealed reservoir and an ambient atmosphere to induce a movement of the at least one flexible portion to perform at least one function for the volatile dispensing system.
Claims18
A volatile dispenser for use in a volatile dispensing system, the volatile dispenser comprising:
- a blister comprising a cup-shaped structure having at least one sidewall perpendicular to a permeable membrane, a peripheral flange, and a bottom surface having a first portion and a second portion, wherein the first portion is more flexible than the second portion;
- the permeable membrane sealable to the peripheral flange and extending across the entire cup-shaped structure to form a sealed reservoir with the blister;
- and
- a volatile material contained within the sealed reservoir,
- wherein a diffusion of the volatile material through the permeable membrane generates a pressure differential inducing a movement of the first portion to perform at least one function for the volatile dispensing system, the pressure differential being between the sealed reservoir and an ambient atmosphere;
- and wherein only the first portion undergoes said movement as a result of the pressure differential.
A volatile dispenser for use in a volatile dispensing system, the volatile dispenser comprising:
- a blister comprising a cup-shaped structure formed from a single sheet, the cup-shaped structure having at least one sidewall and a bottom surface having a first portion and a second portion, wherein the first portion is more flexible than the second portion;
- a permeable membrane sealable to the cup-shaped structure and configured to form a sealed reservoir with the blister;
- and
- a volatile material contained within the sealed reservoir,
- wherein a diffusion of the volatile material through the permeable membrane generates a pressure differential inducing a movement of the first portion to perform at least one function for the volatile dispensing system, the pressure differential being between the sealed reservoir and an ambient atmosphere;
- and wherein only the first portion undergoes said movement as a result of the pressure differential.
