Abstract
Abstract A charge of a condiment such as catsup, mustard or a similar sauce is delivered from a bulk-storage container to a chamber at the end of an air-actuated gun. When the trigger of the gun is actuated to force a piston along the chamber, the charge of condiment is ejected from the gun. When the trigger is released, the piston is retracted toward the rear of the chamber and a new charge of condiment is moved into the chamber under a small amount of pressure from the bulk storage container to a position in front of the piston.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A dispensing device for dispensing condiment in partially liquid form comprising: a housing including a handle section and an elongated dispensing section; means in said housing defining a chamber having a discharge opening, said chamber being disposed in said dispensing section near one end thereof, and said discharge opening being located at said one end, said chamber defining means including an abutment member at the end of the chamber opposite said discharge opening; a plunger mounted for reciprocation in said chamber; spacer means disposed in said chamber between said abutment member and said plunger to limit the movement of said plunger toward said abutment member and thereby determine the condiment receiving volume of said chamber; means for delivering a charge of condiment into that portion of the chamber located between said plunger and the discharge opening; and means for actuating said plunger to discharge substantially all of the condiment contained within said chamber.
Claim 2
Dependent Claim
153 words
A dispensing device for dispensing condiment in partially liquid form comprising: a housing including a handle section and an elongated dispensing section; means in said housing defining a chamber having a discharge opening, said chamber being disposed in said dispensing section near one end thereof, and said discharge opening being located at said one end, said chamber defining means including an abutment member at the end of the chamber opposite said discharge opening; a plunger mounted for reciprocation in said chamber; spacer means disposed in said chamber between said abutment member and said plunger to limit the movement of said plunger toward said abutment member and thereby determine the condiment receiving volume of said chamber; means for delivering a charge of condiment into that portion of the chamber located between said plunger and the discharge opening; and means for actuating said plunger to discharge substantially all of the condiment contained within said chamber.
Claim 3
Dependent Claim
34 words
A dispensing device according to claim 1 wherein the chamber is a cylinder, said plunger is a piston reciprocable in said cylinder, and said actuating means is a power cylinder mounted in said housing.
Claim 4
Dependent Claim
39 words
A dispensing device according to claim 2 wherein said housing is formed into two half-housing members which are mirror images of each other, said device further including means for supporting said power cylinder in fixed position in said housing.
Claim 5
Dependent Claim
31 words
The dispensing device of claim 3 wherein said two half-housing members are formed from a plastic material and are connected by a hinge that is an integral part of each member.
Claim 6
Dependent Claim
55 words
The device of claim 3 wherein said housing is formed of a plastic material and each of said half-housing members includes integrally-formed inwardly extending walls adapted to receive and support said power cylinder in said housing, and means for securing said half-housing members together in face-to-face abutment with said cylinder locked between said housing members.
Claim 7
Dependent Claim
41 words
A dispensing device according to claim 1 wherein said housing is molded from plastic into two half-housing members which are mirror-images of each other, said members having opposed internal support walls adapted to support said plunger for reciprocation in said housing.
Claim 8
Dependent Claim
56 words
The device of claim 1 wherein said housing includes a passage extending through a side wall thereof and communicating with the chamber at a point between the discharge opening and said abutment member, said device further including means for supplying condiment in partially liquid form to said chamber through the passage at a small positive pressure.
