Abstract
Abstract A dispenser consisting of an opened celled housing or vessel forming a chamber of predetermined size permeable to the ingress and egress of fluids more particularly volatile gases to permit escape or dispensing of such gases or other fluids from the chamber into a desired environment. At a critical temperature a means is mounted in or on the vessel for loading and holding of materials to be dissolved or volatilized at the critical temperature and for passing the dissolved substance or the resultant gas to the chamber for dispensing or escape through the permeable walls of the vessel. The material to be dissolved or volatilized will as a general rule be held in a carrier or like device which will degrade or act to release the material to be dissolved or volatilized.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
191 words
A dispenser of the capsule type for use in drying apparatus including; a. housing means made of plastic material with relatively thin walls defining a dispensing chamber, b. said housing means being permeable to permit continuous fluid flow into and out of said dispensing chamber when the dispenser is placed into use in said drying apparatus, c. said housing means having an associated storage means therein including, means forming a retaining space having flow passage means in communication with the dispensing chamber, d. treating material of a type to degrade only at predetermined elevated temperature conditions above ambient atmospheric temperatures, e. said treating material disposed in the retaining space means to permit degraded treating material to pass continuously into and dwell in said dispensing chamber during use of the dispenser, f. said housing having an acess and closure means to permit the storage means to be loaded with treating material from time to time and to prevent escape of degraded treating material other than into the dispensing chamber in the housing, g. and said dispensing chamber having a relatively large volume as compared with the means for retaining the treating material.
Claim 2
Dependent Claim
191 words
A dispenser of the capsule type for use in drying apparatus including; a. housing means made of plastic material with relatively thin walls defining a dispensing chamber, b. said housing means being permeable to permit continuous fluid flow into and out of said dispensing chamber when the dispenser is placed into use in said drying apparatus, c. said housing means having an associated storage means therein including, means forming a retaining space having flow passage means in communication with the dispensing chamber, d. treating material of a type to degrade only at predetermined elevated temperature conditions above ambient atmospheric temperatures, e. said treating material disposed in the retaining space means to permit degraded treating material to pass continuously into and dwell in said dispensing chamber during use of the dispenser, f. said housing having an acess and closure means to permit the storage means to be loaded with treating material from time to time and to prevent escape of degraded treating material other than into the dispensing chamber in the housing, g. and said dispensing chamber having a relatively large volume as compared with the means for retaining the treating material.
Claim 3
Dependent Claim
72 words
In a dispenser of the capsule type for use in drying apparatus as claimed in claim 1 wherein: a. said housing means includes, a first member and a second member, b. said access and closure means includes, means to detachably connect said first meMber to said second member to form the housing means, c. and reinforcing means formed in the respective walls of the first member and second member of the housing.

Claim 6
Dependent Claim
84 words
In a dispenser of the capsule type for use in drying apparatus as claimed in claim 3 wherein said detachable means includes: a. flange means about the open end of said first semi-spherical member, b. L-shaped flange means about the open end of said second semi-spherical member, c. a means on said L-shaped flange to engage and hold said flange means of said first semi-spherical member when said first semi-spherical member and said second semi-spherical member are brought into nested engagement with each other.
Claim 7
Dependent Claim
32 words
