Abstract
Abstract A dispensing device in which the product to be dispensed is aspirated and sprayed by the discharged pressurized air. A valve assembly has a product flow path therethrough and a compressed air flow path therethrough. The valve stem of the assembly is actuated to open the flow paths, and aspirating means is provided at the upper end of said stem for bringing one end of each of said flow paths together. A piston-cylinder assembly is provided on the device having a cylinder with one end around the end of the compressed air flow path, a piston slidable in the cylinder, and a piston rod on said piston and extending out of the other end of said cylinder. A product containing sac has a neck thereon sealed around the end of the product flow path. An actuator means is connected between the piston rod and the valve assembly for moving the valve stem relative to the valve body for opening the flow paths when the piston is moved to the inner end of the cylinder adjacent the valve assembly to provide a predetermined amount of compressed air.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
217 words
A dispensing device comprising: a valve assembly having a valve body, a valve stem movable through said valve body, said valve assembly having a product flow path therethrough and a compressed air flow path therethrough, part of one of said flow paths being through said stem, obturating means associated with said stem for obturating said flow paths and actuated by said stem on movement of said stem to open the flow paths, and aspirating means at the upper end of said stem for bringing one end of each of said flow paths together, the other ends of the flow paths opening out of the valve body remote from said aspirating means, a piston-cylinder assembly having a cylinder with one end around the end of the compressed air flow path, a piston slidable in said cylinder, a piston rod on said piston and extending out of the other end of said cylinder; product containing means coupled to the end of the product flow path remote from the aspirating means; and said piston and piston rod and said valve assembly being operatively associated for moving said valve stem relative to said valve body for causing said obturating means to open said flow paths when said piston is moved to the inner end of said cylinder adjacent said valve assembly.
Claim 2
Dependent Claim
217 words
A dispensing device comprising: a valve assembly having a valve body, a valve stem movable through said valve body, said valve assembly having a product flow path therethrough and a compressed air flow path therethrough, part of one of said flow paths being through said stem, obturating means associated with said stem for obturating said flow paths and actuated by said stem on movement of said stem to open the flow paths, and aspirating means at the upper end of said stem for bringing one end of each of said flow paths together, the other ends of the flow paths opening out of the valve body remote from said aspirating means, a piston-cylinder assembly having a cylinder with one end around the end of the compressed air flow path, a piston slidable in said cylinder, a piston rod on said piston and extending out of the other end of said cylinder; product containing means coupled to the end of the product flow path remote from the aspirating means; and said piston and piston rod and said valve assembly being operatively associated for moving said valve stem relative to said valve body for causing said obturating means to open said flow paths when said piston is moved to the inner end of said cylinder adjacent said valve assembly.
Claim 3
Dependent Claim
216 words
A dispensing device comprising: a valve assembly having a valve body, a hollow valve stem movable through said valve body, said valve assembly having a product flow path therethrough and a compressed air flow path therethrough, part of one of said flow paths being through said stem, obturating means associated with said stem for obturating said flow paths and actuated by said stem on movement of said stem to open the flow paths, and aspirating means at the upper end of said stem for bringing one end of each of said flow paths together, the other ends of the flow paths opening out of the bottom of the valve body; a piston-cylinder assembly having a cylinder with one end around the end of the compressed air flow path, a piston slidable in said cylinder, a pistOn rod on said piston and extending out of the other end of said cylinder; a product containing sac having a neck thereon sealed around the end of the product flow path; and an actuator means connected between said piston rod and said valve assembly for moving said valve stem relative to said valve body for causing said obturating means to open said flow paths when said piston is moved to the inner end of said cylinder adjacent said valve assembly.
Claim 4
Dependent Claim
216 words
A dispensing device comprising: a valve assembly having a valve body, a hollow valve stem movable through said valve body, said valve assembly having a product flow path therethrough and a compressed air flow path therethrough, part of one of said flow paths being through said stem, obturating means associated with said stem for obturating said flow paths and actuated by said stem on movement of said stem to open the flow paths, and aspirating means at the upper end of said stem for bringing one end of each of said flow paths together, the other ends of the flow paths opening out of the bottom of the valve body; a piston-cylinder assembly having a cylinder with one end around the end of the compressed air flow path, a piston slidable in said cylinder, a pistOn rod on said piston and extending out of the other end of said cylinder; a product containing sac having a neck thereon sealed around the end of the product flow path; and an actuator means connected between said piston rod and said valve assembly for moving said valve stem relative to said valve body for causing said obturating means to open said flow paths when said piston is moved to the inner end of said cylinder adjacent said valve assembly.
Claim 5
Dependent Claim
20 words
A dispensing device as claimed in claim 2 in which said piston rod and said piston have a bore therethrough.
Claim 6
Dependent Claim
66 words
A dispensing device as claimed in claim 2 in which said cylinder is engaged with the axial portion of said valve assembly, a housing around said valve assembly and said cylinder and defining an annular space around said cylinder, said product sac being an annular sac and being positioned in said space, said housing having at least one aperture therein for admitting air to said space.
Claim 7
Dependent Claim
51 words
A dispensing device as claimed in claim 2 in which said obturating means are associated with said stem to open said flow paths when said stem is moved into said valve body, and said actuator means is connected with said valve stem for moving said valve stem into said valve body.
Claim 8
Dependent Claim
58 words
A dispensing device as claimed in claim 5 in which said actuator means comprises an actuator sleeve on said valve stem, at least two levers pivotally mounted on said valve assembly and having one end engaged with said sleeve, an an actuator pivotally connected to the other end of each of said levers and to said piston rod.
Claim 9
Dependent Claim
23 words
