Abstract
Abstract A jet-liquid-discharging device for use as an oral spray is provided by a gastight, valved-and-nozzled, refillable container filled with ordinary water into which a gas-producing chemical is to be introduced. A resilient member is provided in the container for multiple purpose of gauging the amount of water used in refilling, for holding the chemical away from the water during refilling, and for providing a gastight seal between the container and its closure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
In a jet-liquid-discharging device that includes a refillable container means for holding therein a liquid under pressure, nozzle means through which a jet of liquid is to be forced under pressure, valve means for selectively controlling discharge from said nozzle means, and the container means providing a selectively closeable opening through which the container may be substantially filled with an unpressurized liquid but leaving a relatively small unfilled space for introduction of a gas-generating material into the container, the improvement comprising, in combination: insert means on the container at the closeable opening providing an apertured support substantially at the level of liquid when the container is substantially filled, with said relatively small space above the support adapted to receive a liquid-soluble, gas-generating material shaped to be supported on said apertured support, a closure member providing a gastight seal for the container, and said insert means being a unitary resilient member having a shallow cup-shape with an outwardly turned flange that serves both to support the insert means upon the container and as a gastight gasket between the container and the closure member.
Claim 2
Dependent Claim
182 words
In a jet-liquid-discharging device that includes a refillable container means for holding therein a liquid under pressure, nozzle means through which a jet of liquid is to be forced under pressure, valve means for selectively controlling discharge from said nozzle means, and the container means providing a selectively closeable opening through which the container may be substantially filled with an unpressurized liquid but leaving a relatively small unfilled space for introduction of a gas-generating material into the container, the improvement comprising, in combination: insert means on the container at the closeable opening providing an apertured support substantially at the level of liquid when the container is substantially filled, with said relatively small space above the support adapted to receive a liquid-soluble, gas-generating material shaped to be supported on said apertured support, a closure member providing a gastight seal for the container, and said insert means being a unitary resilient member having a shallow cup-shape with an outwardly turned flange that serves both to support the insert means upon the container and as a gastight gasket between the container and the closure member.
Claim 3
Dependent Claim
46 words
A device as in claim 1 wherein the nozzle means includes a tubular element integral with the container, said tubular element being shaped to provide an annular attachment boss and an elongated tubular element with A reduced sleeve part frictionally interfitting with the annular attachment boss.
Claim 4
Dependent Claim
103 words
A device as in claim 1 wherein the valve means includes a valve element having a frustoconical body surrounded by a sleevelike seat, at least one of said body and seat being resilient, the large area end of the frustoconical body being exposed to the pressurized liquid to seat with the pressure, an elongated stem extending from the small area end of the frustoconical body for projecting through a control aperture in the wall of the container, and a cup-shaped resilient seal carried by said container in said control aperture and receiving the said portion of the stem projecting through the control aperture.
Claim 5
Dependent Claim
68 words
A device as in claim 1 wherein the container is a generally upright cylinder with the nozzle means extending laterally from adjacent the upper end of the container and the valve means including a control element adjacent the top of the container; the selectively closeable opening being at the opposite end of the cylinder, and the closure for the container being the bottom wall of the closed container.
Claim 6
Dependent Claim
40 words
A device as in claim 3 wherein the valve means includes an elongated dip tube that is resiliently mounted at its connection to the valve means and is of a length to contact the support portion of the insert means.
