Abstract
Abstract A dual inflatable article valve especially useful for balloons including an open ended tubular body member having at least first and second peripherally extending flanges for engagement with a first inflatable article such as a balloon, such engagement being gas tight. A third extending terminal flange is positioned on the end of the body member and is adapted for gas-tight engagement with a second inflatable article, such as a second balloon. The second balloon is generally smaller than the first balloon and is located therein.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
217 words
A valve for at least two inflatable articles such as balloons comprising the combination: an open-ended tubular valve body member having spaced first and second peripheral flanges and a third terminal flange; an aperture in the wall of said body member intermediate said first and second flanges, at least one of said first and second flanges being adapted for gas tight association and engagement with a first inflatable article, said third terminal flange being adapted for gas tight association and engagement with a second inflatable article within said first inflatable article, said second flange having at least one discontinuous wall section; a tubular valve slide member longitudinally movable within said body member and said second inflatable article between an advanced open position and a retracted closed position and being in substantially gas tight sliding engagement with a longitudinally extending peripheral sealing area due to the coaction with the inside of said body member, said slide member being closed at its front end and open at its rear end and having at least one port formed therein between the ends thereof which communicates with a point forwardly of said sealing area when said slide member is in its open position; means for restricting relative movement between said body and slide member; and means for obtaining relative movement therebetween.
Claim 2
Dependent Claim
217 words
A valve for at least two inflatable articles such as balloons comprising the combination: an open-ended tubular valve body member having spaced first and second peripheral flanges and a third terminal flange; an aperture in the wall of said body member intermediate said first and second flanges, at least one of said first and second flanges being adapted for gas tight association and engagement with a first inflatable article, said third terminal flange being adapted for gas tight association and engagement with a second inflatable article within said first inflatable article, said second flange having at least one discontinuous wall section; a tubular valve slide member longitudinally movable within said body member and said second inflatable article between an advanced open position and a retracted closed position and being in substantially gas tight sliding engagement with a longitudinally extending peripheral sealing area due to the coaction with the inside of said body member, said slide member being closed at its front end and open at its rear end and having at least one port formed therein between the ends thereof which communicates with a point forwardly of said sealing area when said slide member is in its open position; means for restricting relative movement between said body and slide member; and means for obtaining relative movement therebetween.
Claim 3
Dependent Claim
20 words
The valvE in accordance with claim 1 wherein said second flange is greater in radial dimension than said first flange.
Claim 4
Dependent Claim
22 words
The valve in accordance with claim 2 wherein said first and second flanges are greater in radial dimension than said third flange.
Claim 5
Dependent Claim
28 words
The valve in accordance with claim 3 wherein said inflatable articles are elastomeric in character to frictionally engage the exterior edges of said first, second and third flanges.
Claim 6
Dependent Claim
28 words
The valve in accordance with claim 3 wherein said slide member is cylindrical and the rear portion thereof is of smaller exterior diameter than the forward portion thereof..
Claim 7
Dependent Claim
32 words
The valve in accordance with claim 5 wherein the exterior surface of said slide member has at least two spaced sealing lips for engagement with the inside bore of said body member.
Claim 8
Dependent Claim
45 words
The valve in accordance with claim 6 wherein said sealing lips are located so that when said slide member is in the closed position, said aperture in the wall of said body member intermediate said first and second flanges is also intermediate said sealing lips.
Claim 9
Dependent Claim
24 words
The valve in accordance with claim 7 wherein said second flange is provided with opposed openings and said body member has a tapered bore.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
36 words
The valve in accordance with claim 8 wherein the terminal portion of said body member opposite said third terminal flange is adapted to engage the exterior cylindrical surface of said slide member in gas tight relationship.
Claim 12
Dependent Claim
41 words
The valve in accordance with claim 10 wherein means for restricting relative movement between said body and slide members comprises the cooperation of the rear edge of said slide member abutting the interior closed rear portion of said valve body member.
Claim 13
Dependent Claim
58 words
The valve in accordance with claim 11 wherein said rear edge abutting said interior closed rear portion of said valve body member forms a gas-tight sealing area and said means for obtaining relative movement between said body and slide members comprises an interior abutment shoulder located on the interior of said slide member adjacent the forward end thereof.
Claim 14
Dependent Claim
22 words
The valve in accordance with claim 12 wherein said body and slide members are formed of molded plastic of slightly deformable character.
Claim 15
Dependent Claim
