Abstract
Abstract An elastic balloon mounted on a hollow valve body which projects from the mouth of the balloon neck and is open axially only at its open end, with radial passages in the valve body being normally sealed by elastic engagement of the balloon neck therearound, is inflated with gas under pressure supplied to the interior of the valve body through a nozzle structure engaged by the valve body and functioning to prevent the escape of such gas from the valve body except into the balloon. The nozzle structure comprises a core member dimensioned to extend into the valve body and having bores for the passage of the inflating gas therethrough and a frusto-conical surface for sealing engagement by the valve body at its open end, and an annular member extending around, and spaced from the core member and having an inner surface for engagement with the thickened rim at the mouth of the balloon neck.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
348 words
A nozzle structure for use in inflating an elastic balloon having a neck with a thickened rim at the open mouth thereof and which engages elastically about a generally cylindrical hollow valve body that projects at one end from said mouth of the ballon neck and is open axially only at said one end with radial passages in the valve body being normally sealed by the elastic engagement of the balloon neck therearound; said nozzle structure comprising a core member supported at one end and dimensioned at its other end portion to extend with clearance into said one open end of the valve body, said core member having a frusto-conical part disposed adjacent said other end portion and tapering in the direction toward the latter, an elastomeric sealing sleeve extending around at least said frusto-conical part and elastically conforming to the surface of the latter for sealing engagement with the open end of the valve body when said other end portion of the core member extends into the valve body, said core member further having an axial bore for receiving an inflating gas under pressure at said one end of the core member and radial bores extending from said axial bore and having openings at a peripheral surface of said other end portion of the core member onto which said sleeve extend, for normally covering said radial bores, so that, when the inflating gas under pressure is supplied to said axial bore, the gas acts at said radial bores to distend said sleeve away from said peripheral surface of said other end portion and into sealing engagement with the inner surface of a valve body on said core member which valve body is supplied with the gas from said radial bores, and an annular member extending around, and spaced radially from said other end portion of the core member and having an inner surface for engagement with the thickened rim of a balloon when the open end of the respective valve body is in sealing engagement with said sealing sleeve on said frusto-conical part of the core member.
Claim 2
Dependent Claim

A nozzle structure for use in inflating an elastic balloon having a neck with a thickened rim at the open mouth thereof and which engages elastically about a generally cylindrical hollow valve body that projects at one end from said mouth of the ballon neck and is open axially only at said one end with radial passages in the valve body being normally sealed by the elastic engagement of the balloon neck therearound; said nozzle structure comprising a core member supported at one end and dimensioned at its other end portion to extend with clearance into said one open end of the valve body, said core member having a frusto-conical part disposed adjacent said other end portion and tapering in the direction toward the latter, an elastomeric sealing sleeve extending around at least said frusto-conical part and elastically conforming to the surface of the latter for sealing engagement with the open end of the valve body when said other end portion of the core member extends into the valve body, said core member further having an axial bore for receiving an inflating gas under pressure at said one end of the core member and radial bores extending from said axial bore and having openings at a peripheral surface of said other end portion of the core member onto which said sleeve extend, for normally covering said radial bores, so that, when the inflating gas under pressure is supplied to said axial bore, the gas acts at said radial bores to distend said sleeve away from said peripheral surface of said other end portion and into sealing engagement with the inner surface of a valve body on said core member which valve body is supplied with the gas from said radial bores, and an annular member extending around, and spaced radially from said other end portion of the core member and having an inner surface for engagement with the thickened rim of a balloon when the open end of the respective valve body is in sealing engagement with said sealing sleeve on said frusto-conical part of the core member.
Claim 3
Dependent Claim
34 words
A nozzle structure according to claim 1, in which said inner surface of the annular member is tapered to increase in diameter in the axial direction toward said other end of the core member.
Claim 4
Dependent Claim
23 words
A nozzle structure according to claim 1, in which said axial bore also opens axially at said other end of the core member.
