Abstract

Abstract A dispenser for flowable materials such as toothpaste includes a hollow barrel containing the material. A dispensing spout extends outwardly from the closed end of the barrel with a cap removably mounted thereon. A plunger is slidably mounted in the barrel in such a manner that the barrel may be pushed downwardly with respect to the plunger to cause the material to flow from the spout

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 173 words
A dispenser for a flowable material comprising a hollow rigid barrel containing a supply of the flowable material, said barrel having an open lower end and a closed upper end, a dispensing spout extending outwardly from said closed upper end and communicating with the interior of said barrel, a cap removably mounted on said dispensing spout for selectively opening and closing said dispensing spout, a rigid plunger slidably mounted in said barrel, said plunger being longer than the length of the inside of said barrel whereby the lower end of said plunger is always extended outwardly from said barrel, the upper end of said plunger being a closed wall of a size and shape conforming to the inside peripheral surface of said barrel whereby said closed wall functions as a piston head when there is relative motion of said closed wall toward said dispensing spout to force said flowable material through said dispensing spout when said cap is removed therefrom, and stop means preventing said closed wall from being withdrawn from said barrel.
Claim 2
Dependent Claim 173 words
A dispenser for a flowable material comprising a hollow rigid barrel containing a supply of the flowable material, said barrel having an open lower end and a closed upper end, a dispensing spout extending outwardly from said closed upper end and communicating with the interior of said barrel, a cap removably mounted on said dispensing spout for selectively opening and closing said dispensing spout, a rigid plunger slidably mounted in said barrel, said plunger being longer than the length of the inside of said barrel whereby the lower end of said plunger is always extended outwardly from said barrel, the upper end of said plunger being a closed wall of a size and shape conforming to the inside peripheral surface of said barrel whereby said closed wall functions as a piston head when there is relative motion of said closed wall toward said dispensing spout to force said flowable material through said dispensing spout when said cap is removed therefrom, and stop means preventing said closed wall from being withdrawn from said barrel.
Claim 3
Dependent Claim 33 words
The dispenser of claim 1 wherein said plunger is longer than the length of the inside of said barrel whereby the lower end of said plunger is always extended outwardly from said barrel.
Claim 4
Dependent Claim 42 words
The dispenser of claim 2 wherein the lower end of said plunger is outwardly flared to facilitate said dispenser standing upright on said flared end and to permit the material to be dispensed when said barrel is moved in a downward direction.
Claim 5
Dependent Claim 48 words
The dispenser of claim 3 wherein said stop means comprises finger means extending inwardly from said open lower end of said barrel, said upper end of said plunger having an outwardly extending peripheral rim snapped over said finger means, and sealing means being provided on said peripheral rim.
Claim 6
Dependent Claim 11 words
The dispenser of claim 4 wherein said material is non-food contents.
Claim 7
Dependent Claim 10 words
The dispenser of claim 5 wherein said material is toothpaste.
Claim 8
Dependent Claim 35 words
The dispenser of claim 6 wherein the outer surface of said closed upper end of said barrel has ornamentation thereon whereby said dispenser may function as a toy after its contents have been fully dispensed.
Claim 9
Dependent Claim 24 words
The dispenser of claim 7 wherein said ornamentation is in the form of a face, and said cap comprising the nose of said face.
Claim 10
Independent Claim 125 words
A method of dispensing a flowable material in a hollow rigid barrel having a closed upper end and an open lower end, snapping a plunger into the open lower end of the barrel, providing a dispensing spout in the closed upper end of the barrel, snapping a cap over the dispensing spout to temporarily close the dispensing spout, extending the dispenser on its end with the dispensing spout being uppermost and the lower end of the plunger resting on a support surface, removing the cap from the dispensing spout, pushing the barrel downwardly to cause a selected amount of material to be dispensed from the dispensing spout, and snapping the cap back on the dispensing spout after the selected amount of material has been dispensed.
Claim 11
Independent Claim 125 words
A method of dispensing a flowable material in a hollow rigid barrel having a closed upper end and an open lower end, snapping a plunger into the open lower end of the barrel, providing a dispensing spout in the closed upper end of the barrel, snapping a cap over the dispensing spout to temporarily close the dispensing spout, extending the dispenser on its end with the dispensing spout being uppermost and the lower end of the plunger resting on a support surface, removing the cap from the dispensing spout, pushing the barrel downwardly to cause a selected amount of material to be dispensed from the dispensing spout, and snapping the cap back on the dispensing spout after the selected amount of material has been dispensed.
