Abstract

Abstract A dispenser valve structure for use with containers dispensing liquids under pressure, in which the nozzle is provided with spaced guide ribs which form guideways therebetween for guiding the material to be discharged in a substantially straight stream and avoid spattering. This invention is an improvement of the type of valve structure shown in my U.S. Pat. No. 3,300,105.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 279 words
In combination with a container for dispensing liquids under pressure, said container including a closure having an opening therethrough, a resilient tubular plug extending through said opening and having a flange engaging the inner surface of said closure and an annular outwardly extending shoulder above said flange with the underside of said shoulder engaging the container closure to secure said plug to said closure, said plug being provided with a valve seat on its inner side, said plug having a tubular portion, a rigid valve stem of lesser diameter than the internal diameter of said tubular plug, said valve stem being provided at its inner end with a valve head adapted to engage said seat and being provided at its other end with an outer head having engaging surfaces extending laterally of said stem, a separate nozzle positioned on said tubular plug, said nozzle having an inner shoulder adapted to be engaged by said engaging surfaces of said valve stem, said nozzle formed to provide a plurality of spaced finger-like tips at the outer end thereof, each of said tips having a pair of spaced vertically extending guide members integrally formed on the inside thereof with each said pair of guide members forming a guideway to direct the stream of the material being discharged through said guideway in a substantially straight stream outwardly of said finger-like tips of said nozzle in a direction substantially parallel with the vertical axis of the nozzle to reduce spattering, said guide members each having a uniform width along its length and providing a guideway between each said pair of guide members, said guideway being of uniform width along the length of the guideway.
Claim 2
Dependent Claim 279 words
In combination with a container for dispensing liquids under pressure, said container including a closure having an opening therethrough, a resilient tubular plug extending through said opening and having a flange engaging the inner surface of said closure and an annular outwardly extending shoulder above said flange with the underside of said shoulder engaging the container closure to secure said plug to said closure, said plug being provided with a valve seat on its inner side, said plug having a tubular portion, a rigid valve stem of lesser diameter than the internal diameter of said tubular plug, said valve stem being provided at its inner end with a valve head adapted to engage said seat and being provided at its other end with an outer head having engaging surfaces extending laterally of said stem, a separate nozzle positioned on said tubular plug, said nozzle having an inner shoulder adapted to be engaged by said engaging surfaces of said valve stem, said nozzle formed to provide a plurality of spaced finger-like tips at the outer end thereof, each of said tips having a pair of spaced vertically extending guide members integrally formed on the inside thereof with each said pair of guide members forming a guideway to direct the stream of the material being discharged through said guideway in a substantially straight stream outwardly of said finger-like tips of said nozzle in a direction substantially parallel with the vertical axis of the nozzle to reduce spattering, said guide members each having a uniform width along its length and providing a guideway between each said pair of guide members, said guideway being of uniform width along the length of the guideway.
Claim 3
Dependent Claim 18 words
A structure as defined in claim 1 in which the nozzle is integrally molded of a plastic material.
Claim 4
Dependent Claim 42 words
A structure as defined in claim 1 in which the tips are curved inwardly, said guide members being ribs which extend into the interior of said nozzle, with the top of said guide ribs terminating below the top of said finger-like tips.
Claim 5
Dependent Claim 44 words
A structure as defined in claim 1 in which a slot is provided between each of the finger-like tips, with the guide members extending outwardly of the bottom of the slot and also extending inwardly of said slot into the interior of said nozzle.
Claim 6
Dependent Claim 55 words
A structure as defined in claim 4 in which the guide members are ribs and in which the nozzle and ribs are integrally molded of a plastic material and in which the adjacent ribs form a spaced area between each slot, said last mentioned area being of less wiDth than the width of each guideway.
