Abstract
A resiliently deformable member for use in an apparatus for dispensing a viscous material from a container, such as an apparatus consisting of a container for holding the viscous material and a dispensing gun. The resiliently deformable member has a relaxed state and a compressed state. In use, the resiliently deformable member applies a force between the container and the dispensing gun to modulate the flow of the material from the container.
Claims9
An apparatus for dispensing a viscous material, the apparatus comprising:
- a dispensing gun including a plunger;
- a container for holding the viscous material, the container comprising a first end having a nozzle, a second end opposite the first end, and a bottom cap recessed within the second end, wherein the bottom cap is configured to be shifted from the second end toward the first end of the container upon pushing of the plunger into the second end of the container to dispense the viscous material from the nozzle during use of the dispensing gun;
- and
- a resiliently deformable member including a compression spring interposed between first and second slidable cap enclosures, said resiliently deformable member being at least partially recessed within the second end of the container and entirely between the bottom cap and the plunger, the resiliently deformable member having a relaxed state and a compressed state, wherein the resiliently deformable member is configured to shift between the relaxed and compressed states to modulate a flow of the viscous material from the container when the dispensing gun is in use.
A method of modulating a flow of viscous material from a container disposed in a dispensing gun, with the container having a nozzle end for dispensing the viscous material and a plunger end, including a bottom cap, for receiving a plunger of the dispensing gun, the method comprising:
- (a) providing a resiliently deformable member between the bottom cap and the plunger, the resiliently deformable member including first and second slidable cap enclosures and a compression spring interposed between the first and second cap enclosures, said resiliently deformable member being at least partially recessed within the container and entirely between the bottom cap and the plunger, while having a relaxed state and a compressed state;
- (b) dispensing at least a portion of the viscous material from the container by operating the dispensing gun to cause the plunger to engage the second cap enclosure, compress the compression spring through the second cap enclosure and shift the bottom cap through engagement with the first cap enclosure, wherein the resiliently deformable member is employed to apply a force between the container and the dispensing gun and to modulate flow of the viscous material from the container.
A resiliently deformable member configured to be positioned between a bottom cap, located within a container for holding a viscous material, and a plunger of a dispensing gun, comprising:
- first and second slidable cap enclosures;
- and
- a compression spring interposed between the first and second cap enclosures, said resiliently deformable member being configured to be at least partially recessed within the container and entirely between the bottom cap and the plunger, the resiliently deformable member having a relaxed state and a compressed state, wherein the resiliently deformable member is configured to shift between the relaxed and compressed states to modulate a flow of the viscous material from the container when the dispensing gun is in use.
