Abstract
Abstract Apparatus for dispensing fluid materials contained in a readily deformable inner container which is located within a resilient outer container. The inner container and a nozzle are permanently affixed to one another and the nozzle has a first one-way check valve permitting ejection of the contents from the inner container. The resilient outer container has a second one-way valve to admit air from the exterior of the device to the space between the inner and outer containers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
276 words
A device for dispensing a predetermined material comprising: a readily deformable inner containment portion having a closed end and an open end for containing said material to be dispensed and a dispensing channel portion having a first one-way valve therein oriented to allow dispensing of said material from said inner containment portion but substantially precluding passage of matter into said inner containment portion through said dispensing conduit portion, said dispensing channel portion including an inlet terminus and a base section, said inlet terminus having said first one-way valve positioned thereat and defining an inner circumference of said base section, and said base section having an outer circumference in a spaced relationship from said inner circumference, the area between said inner circumference and said outer circumference defining a curved surface therebetween extending away from said closed end of said inner containment portion, said inner containment portion adjacent said open end and said dispensing channel portion being permanently affixed at said outer circumference of said base section of said dispensing channel portion; and a resilient outer containment portion and a nozzle said resilient outer containment portion for receiving and containing said inner containment portion without direct attachment of said readily deformable inner containment portion and said resilient outer containment portion, said dispensing channel portion and said nozzle being permanently affixed to one another, said resilient outer containment portion including a second one-way valve positioned to permit flow of matter from the exterior of said outer containment portion to the volume defined between said outer containment portion and said inner containment portion but substantially precluding passage of matter from said volume to the exterior of said outer containment portion.
Claim 2
Independent Claim
276 words
A device for dispensing a predetermined material comprising: a readily deformable inner containment portion having a closed end and an open end for containing said material to be dispensed and a dispensing channel portion having a first one-way valve therein oriented to allow dispensing of said material from said inner containment portion but substantially precluding passage of matter into said inner containment portion through said dispensing conduit portion, said dispensing channel portion including an inlet terminus and a base section, said inlet terminus having said first one-way valve positioned thereat and defining an inner circumference of said base section, and said base section having an outer circumference in a spaced relationship from said inner circumference, the area between said inner circumference and said outer circumference defining a curved surface therebetween extending away from said closed end of said inner containment portion, said inner containment portion adjacent said open end and said dispensing channel portion being permanently affixed at said outer circumference of said base section of said dispensing channel portion; and a resilient outer containment portion and a nozzle said resilient outer containment portion for receiving and containing said inner containment portion without direct attachment of said readily deformable inner containment portion and said resilient outer containment portion, said dispensing channel portion and said nozzle being permanently affixed to one another, said resilient outer containment portion including a second one-way valve positioned to permit flow of matter from the exterior of said outer containment portion to the volume defined between said outer containment portion and said inner containment portion but substantially precluding passage of matter from said volume to the exterior of said outer containment portion.
Claim 3
Dependent Claim
30 words
The device for dispensing material of claim 1 wherein said inner containment portion, said dispensing channel portion, and said outer containment portion are permanently affixed to provide a unitary structure.
Claim 4
Dependent Claim
18 words
The device for dispensing material of claim 1 wherein at least said first one-way valve comprises flapper valve.
Claim 5
Dependent Claim
53 words
The device for dispensing material of claim 1 wherein said outer containment portion includes a body portion and wherein said nozzle and said body portion have opposed engagable surfaces comprising an outwardly facing engaging surface on said nozzle and an inwardly facing engaging surface on said body portion of said outer containment portion.
Claim 6
Dependent Claim
27 words
The device for dispensing material of claim 1 wherein said nozzle includes a cap means for selectively disenabling passage of said material from said dispensing channel portion.
Claim 7
Dependent Claim
16 words
The device for dispensing material of claim 1 said nozzle further comprising a nozzle extender for.
Claim 8
Dependent Claim
41 words
The device for dispensing material of claim 16 wherein said resilient outer containment portion includes a body section and a retainer ring section engagable with said body section, and wherein said nozzle is maintained near said engagement of said ring section.
Claim 9
Dependent Claim
53 words
The device for dispensing material of claim 7 wherein said nozzle includes an annular ridge for engaging said body section, and wherein said body section and said retainer ring section have opposed engagable surfaces whereupon engagement of said opposed surfaces said annular ridge is clamped between said body section and said ring section.
