Abstract
A dispensing device is provided for storing and dispensing a flowable, viscous material. A cartridge is provided for storing the material and includes a tube, a movable cup member located within the tube, an end wall having a nozzle opening covered with a removable seal and a nozzle. The nozzle is removably held within the cup member during storage. The dispensing device is formed by inserting the cartridge within the actuator. The actuator comprises a barrel, a trigger, a handle, a plunger and a resilient detent. The movement of the trigger causes the plunger to push the moveable member forward. The detent holds the plunger in place maintaining the flow of material.
Claims21
A cartridge for holding viscous material comprising:
- a tube with a first end having a end wall and a nozzle opening therein, a second end forming a second opening is provided at the opposite end of the tube from the end wall;
- a removable seal covering the nozzle opening;
- a cup member located within the second end of the tube and longitudinally movable within the tube, the moveable member having a bottom and one or more sidewalls for sealing with inside walls of the tube;
- and
- a nozzle formed for attachment to the nozzle opening in the end wall, the nozzle sized and dimensioned for securing within the sidewalls of the moveable member during shipment and storage,
- the tube, tube end wall and bottom of the cup member combining to define a chamber for storing the viscous material.
A dispensing device comprising:
- a cartridge, the cartridge comprising
- a tube with a closed first end and an open second end;
- a movable member located within second end of the tube and longitudinally movable within the tube;
- and
- a nozzle secured to the first end,
- wherein the tube, the moveable member, and the closed first end define a chamber for storing a flowable material;
- an actuator, the actuator comprising
- a barrel configured to hold the cartridge;
- a handle attached to the barrel;
- a plunger rod having a first plurality of teeth and a second plurality of teeth along the rod length;
- a trigger, the trigger pivotably connected to the handle and movable between a first position and a second position, and at least one tooth is provided on the trigger and associated with the first plurality of teeth on the rod;
- and
- a detent, the detent defined by a leg, wherein the leg flexibly engages a tooth on the second plurality of teeth;
- wherein movement of the trigger from the first position to the second position causes the at least one tooth to engage the first plurality of teeth on the rod and to linearly move the rod in a forward direction, the movement of the plunger causes the moveable member to move forward within the tube and forces the contents of the cartridge through the nozzle, and
- wherein the leg of the detent engages a tooth on the second plurality of teeth to retain the rod in the second position after movement.
An actuator for use along with a cartridge retaining a volume of a flowable material to form a dispensing device, the cartridge of the type having a tube with a closed first end and an open second end, a movable member located within second end of the tube and longitudinally movable within the tube, and a nozzle secured to the first end, the actuator comprising:
- a barrel configured to hold the cartridge;
- a handle attached to the barrel;
- a plunger rod having a first plurality of teeth and a second plurality of teeth along the rod length;
- a trigger, the trigger pivotably connected to the handle and movable between a first position and a second position, and at least one tooth is provided on the trigger and associated with the first plurality of teeth on the rod;
- and
- a resilient detent having a leg, wherein the leg flexibly engages a tooth on the second plurality of teeth;
- wherein movement of the trigger from the first position to the second position causes the at least one tooth to engage the first plurality of teeth on the rod and to linearly move the rod in a forward direction, the movement of the plunger causes the moveable member to move forward within the tube and forces the contents of the cartridge through the nozzle, and
- wherein the second leg of the detent engages a tooth on the second plurality of teeth to retain the rod in the second position after movement.
