Abstract
Abstract The embodiment of the invention disclosed herein is directed to a fluid dispensing device which is usable as a condiment dispenser for such things as ketchup, mustard, mayonnaise or the like. The dispensing device has a hand-manipulated flexible housing which is provided with an access opening at the top thereof and an outlet port at the bottom. The access opening is adapted to receive a container which is formed of film material and which supports the fluid substance to be placed into the dispensing device. The container is insertable into the housing so that a nozzle or valve element is positioned at the bottom of the container and fits through the outlet port from where the fluid substance can be dispensed. A check valve member is formed in the housing so that upon manual squeezing of the housing pressure is applied to the film container and the fluid substance is thereby dispensed. Upon releasing hand pressure of the housing, atmospheric pressure is pulled into the housing by opening of the check valve. The dispensing nozzle is formed as part of the film container rather than part of the outer support housing. The nozzle is a single, integral element having a starter passage portion into which an initial quantity of fluid substance flows prior to initial opening of the valve, a seal portion downstream of the starter passage portion which is resiliently opened and closed by the normal elasticity of the material forming the nozzle, and a dispensing end completely closeable so that the fluid substance is not left about the nozzle when the upstream seal is in a closed condition.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
334 words
In a fluid dispensing device the combination comprising: a housing of resilient material having an access opening and an outlet port, a container formed of flexible film material for receiving therein a quantity of fluid substance to be dispensed, said container being readily insertable into said housing through said access opening, and a nozzle secured to and forming part of said container and insertable into said outlet port of said housing, whereby squeezing said housing will apply pressure to the outer surface of said container to dispense the fluid substance therein through said nozzle, said access opening being formed at the top of said housing and said outlet port being formed through a bottom wall of said housing, the interior surface of the bottom wall of said housing having a major area thereof inclined downwardly and a minor area thereof oriented substantially parallel to the outside surface of said bottom wall, said outlet port being formed in said minor area, whereby fluid substance in said container is at all times directed down the inclined surface toward said nozzle to provide an initial quantity of fluid substance within said nozzle, said housing including check valve means formed in the top wall of said housing to allow pressure buildup within the housing upon squeezing the same and to allow entrace of atmospheric air therethrough when releasing the squeezing pressure on said housing, thereby allowing rapid expansion of said housing to its normal configuration after dispensing a given quantity of the fluid substance, said check valve means including an aperture formed in the top wall of said housing, an arm secured to the top wall of said housing and displaced from said aperture, said arm extending toward said aperture, and a protuberance extending upwardly from said arm and engaging the periphery of said aperture to form a seal therewith upon squeezing of said housing and wherein atmospheric pressure will urge said protuberance and said arm away from said aperture to allow atmospheric air to enter said housing.
Claim 2
Dependent Claim
334 words
In a fluid dispensing device the combination comprising: a housing of resilient material having an access opening and an outlet port, a container formed of flexible film material for receiving therein a quantity of fluid substance to be dispensed, said container being readily insertable into said housing through said access opening, and a nozzle secured to and forming part of said container and insertable into said outlet port of said housing, whereby squeezing said housing will apply pressure to the outer surface of said container to dispense the fluid substance therein through said nozzle, said access opening being formed at the top of said housing and said outlet port being formed through a bottom wall of said housing, the interior surface of the bottom wall of said housing having a major area thereof inclined downwardly and a minor area thereof oriented substantially parallel to the outside surface of said bottom wall, said outlet port being formed in said minor area, whereby fluid substance in said container is at all times directed down the inclined surface toward said nozzle to provide an initial quantity of fluid substance within said nozzle, said housing including check valve means formed in the top wall of said housing to allow pressure buildup within the housing upon squeezing the same and to allow entrace of atmospheric air therethrough when releasing the squeezing pressure on said housing, thereby allowing rapid expansion of said housing to its normal configuration after dispensing a given quantity of the fluid substance, said check valve means including an aperture formed in the top wall of said housing, an arm secured to the top wall of said housing and displaced from said aperture, said arm extending toward said aperture, and a protuberance extending upwardly from said arm and engaging the periphery of said aperture to form a seal therewith upon squeezing of said housing and wherein atmospheric pressure will urge said protuberance and said arm away from said aperture to allow atmospheric air to enter said housing.
Claim 3
Dependent Claim
65 words
In the fluid dispensing device of claim 1 wherein the bottom portion of said housing has a predetermined depth and wherein said nozzle on said container extends through said outlet port and is of a length less than the depth of said bottom portion of said housing so as not to come in direct contact with the surface upon which the dispensing device is positioned.
Claim 4
Dependent Claim
251 words
In a fluid dispensing device the combination comprising: a housing of resilient material having means providing access to the interior thereof and an outlet port, and a container readily insertable into the interior of said housing and formed of flexible film material for receiving therein a quantity of fluid substance to be dispensed, said container having a filler opening to be sealed for isolating said substance and a nozzle secured to and Forming part of said container and insertable into said outlet port whereby squeezing said housing will apply pressure to the outer surface of said container to dispense the fluid substance therein through said nozzle, said device further including check valve means formed in said housing and opening into said housing spaced from said container to allow pressure buildup within the housing upon squeezing the same and to allow entrance of atmospheric air therethrough when releasing the squeezing pressure on said housing, thereby allowing rapid expansion of said housing to its normal configuration after dispensing a given quantity of the fluid substance, said check valve means including an aperture formed in a wall of said housing, an arm secured to said housing wall and displaced from said aperture and extending toward said aperture, and a protuberance extending from said arm and engaging the periphery of said aperture to form a seal therewith upon squeezing of said housing and wherein atmospheric pressure will urge said protuberance and said arm away from said aperture to allow atmospheric air to enter said housing.
Claim 5
Dependent Claim
251 words
