Abstract
Abstract A dispensing package for a volatile composition such as a room deodorant and the like that comprises a container having at least two chambers. In one of the chambers is packaged a bed of inert solid, adsorbent granules having absorbed thereon a volatile ingredient for dispensing into the atmosphere. The container has an outlet vapor port in a wall of the chamber and a second vapor inlet port which communicates with a second chamber; the latter having a collapsible wall surface. A check valve is provided in the wall of the second chamber to permit air intake whereby volatile components adsorbed on the surface of the solid bed of granules can be dispensed into the atmosphere by pumping the collapsible wall of the second chamber, thereby forcing air through the bed of solid granules and desorbing of the the volatile adsorbate, which is dispensed into the atmosphere. Preferably, the bed of solid adsorbent is formed with a plurality of volatile components of different volatilities which are each adsorbed onto an inert carrier to provide a plurality of volatile-component-bearing, solid fractions which are blended together in preselected proportions to provide the desired proportional release rate of each of the volatile components.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
161 words
A volatile component dispensing package comprising: a. container means having an apertured internal wall subdividing said container into internal, first and second chambers; b. a collapsible external wall portion sealingly mounted to, and defining an external wall of said second chamber of, said container; c. a single check valve in the external wall of said chamber, directly communicating with said second chamber to permit air intake directly into said second chamber; d. a bed of inert solid adsorbent granules within said first chamber; e. a volatile ingredient for dispensing into the atmosphere adsorbed on said solid adsorbent granules; and f. a vapor outlet port in the external wall of said container directly communicating with said first chamber whereby air can be induced through said single check valve means into said second chamber and forced therefrom through said apertured internal wall to flow through said solid adsorbent and desorb said volatile ingredient and discharge with said volatile ingredient through said outlet port.
Claim 2
Dependent Claim
161 words
A volatile component dispensing package comprising: a. container means having an apertured internal wall subdividing said container into internal, first and second chambers; b. a collapsible external wall portion sealingly mounted to, and defining an external wall of said second chamber of, said container; c. a single check valve in the external wall of said chamber, directly communicating with said second chamber to permit air intake directly into said second chamber; d. a bed of inert solid adsorbent granules within said first chamber; e. a volatile ingredient for dispensing into the atmosphere adsorbed on said solid adsorbent granules; and f. a vapor outlet port in the external wall of said container directly communicating with said first chamber whereby air can be induced through said single check valve means into said second chamber and forced therefrom through said apertured internal wall to flow through said solid adsorbent and desorb said volatile ingredient and discharge with said volatile ingredient through said outlet port.
Claim 3
Dependent Claim
27 words
The package of claim 1 wherein said single check valve comprises an aperture with a flap closure member carried on the inside wall to overlie said aperture.
Claim 4
Dependent Claim
32 words
The package of claim 1 wherein said solid adsorbent and volatile ingredient adsorbate provide an adsorption isotherm characteristic of substantially constant vapor pressure as a function of the concentration of said adsorbate.
Claim 5
Dependent Claim
16 words
The package of claim 3 wherein said solid adsorbent comprises particulate solids of substantially spherical shape.
Claim 6
Dependent Claim
11 words
The package of claim 3 wherein said solid adsorbent is silica.
Claim 7
Dependent Claim
11 words
The package of claim 3 wherein said solid adsorbent is charcoal.
Claim 8
Dependent Claim
95 words
The package of claim 1 wherein said bed of inert solid adsorbent granules comprises an admixture of a plurality of inert solid fractions, each fraction comprising an inert, particulate solid carrier having adsorbed thereon a volatile ingredient of a volatile-dispensing composition to provide volatile, component-bearing solid fraction of preselected specific surface area, adsorbate concentration, particle size and adsorption isotherm characteristics and admixed with the other solid fractions at a concentration to provide a proportional release rate of its respective volatile component whereby the vapor released from said deodorant product is of a preselected, desired composition.
Claim 9
Dependent Claim
29 words
The package of claim 7 wherein said solid fractions have preselected adsorption isotherm characteristics to release a vapor of substantial constant composition throughout the useful life of said product.
Claim 10
Dependent Claim
11 words
The package of claim 7 wherein said solid carrier is charcoal.
Claim 11
Dependent Claim
11 words
The package of claim 7 wherein said solid carrier is silica.
Claim 12
Dependent Claim
13 words
The package of claim 7 wherein said solid carrier is expanded calcium silicate.
Claim 13
Dependent Claim
12 words
The package of claim 7 wherein said volatile-dispensing composition is a deodorant.
