Various aspects and embodiments are directed to a precision dispenser that is hand held and constructed and arranged to receive and release a variety of glue cartridges. In various embodiments, the adhesive cartridges include precision tips that provide, for example, flat even bead with little or no spill or drip. Other precision tips can be constructed and arranged for use with the precision glue gun. In some examples, the precision tips can be tailored to the specific adhesive contained in the cartridge.

Embodiments of the present invention includes methods for dispensing and an apparatus for dispensing. In particular embodiments, the barrel design of an apparatus for dispensing and provided in a method for dispensing is formed to encase and/or engage a material container. By encasing and/or engaging the material container within the barrel, expansion, such as tube expansion, is reduced and/or eliminated.

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.

A dispenser for mixing and dispensing a multi-component adhesive or sealant includes a first motor operably coupled to two or more plungers, each plunger being slidably disposed in a respective one of two or more barrels and configured to apply a dispensing pressure to respective materials to be dispensed, a second motor operably coupled to an output drive shaft having a mating end, and a coupling plate removably attached to a front end of the dispenser, the coupling plate configured to attach to a disposable mixer attachment configured to mix and dispense the multi-component adhesive or sealant, the disposable mixer attachment having a drive shaft driving a mixing component and configured to selectively couple with the mating end of the output drive shaft of the second motor, thereby enabling dynamic mixing of the respective materials to be dispensed.

A cartridge for a viscous-material dispenser includes a cylinder and a plunger axially slidably fitted in the cylinder and dividing the cylinder into a filling chamber and a pressurizing chamber and includes a plurality of solid spacers in an annular gap between the plunger and the cylinder for maintaining a minimum spacing between the plunger and the cylinder. The spacers at least partially define a plurality of passages that fluidically connect the filling and pressurizing chambers and are configured such that a first portion of the viscous material extending from the filling chamber into the plurality of passages forms a seal together with the solid spacers to prevent a second portion of the viscous material located in the filling chamber from entering the plurality of passages.

A device suitable for finishing and sealing the joints and openings of different surfaces is described here. The device includes a base, which is conical in its essence. The base has a collar to connect the device to the gun of sealant of finishing material; a holder is integrated with the base at an angle, a movable smoothing pad with a carriage is fitted in the holder, and the carriage is installed in a casing inside holder. In the working position, there is a space between the smoothing pad and the tip of the nozzle of the tube, so that the material which is applied from the tube to the surface can visually be monitored and thus the desirable quantity dosed during the performance of the works.

A dispensing tool for dispensing caulk includes a cartridge housing shaped to receive a cartridge of caulk. The cartridge includes a support bracket which extends to a pivot element, and an applicator head is mounted on the pivot element. A material hose connects the exit nozzle of the cartridge with the applicator head. A dispensing nozzle of the applicator head dispenses the caulk flowing from the cartridge. The cartridge includes a drive mechanism to push the follower of the cartridge to dispense the caulk, and a reciprocation system reciprocates the applicator head as the caulk is being dispensed through the dispensing nozzle.

A caulking gun is provided, including: a gun body, including a cartridge holder, the cartridge holder being adapted for receiving a caulk cartridge; a pushing rod, movably assembled to the gun body and extending into the cartridge holder, the pushing rod having a pushing portion which is movable within the cartridge holder and is adapted for pushing the caulk cartridge, and a hook pull portion connected with the pushing portion, the hook pull portion including a first hook portion and a second hook portion, at least one of the first hook portion and the second hook portion being movable to the other of the first hook portion and the second hook portion.

An extensible adhesive dispensing gun system. A syringe has a piston for urging an adhesive out of a nozzle, and a first mount at a back end of the syringe. A gun body contains a mechanism for advancing a plunger from a front end of the body in response to a trigger, and a second mount is disposed on the front end. An extension tube assembly includes an outer tube having near and far end adapters. A third mount on the near end adapter engages the second mount on the gun body, and a fourth mount on the far end adapter engages the first mount on the syringe. An inner rod member is arranged inside the outer tube. When the gun plunger is urged against a back end of the rod member, a leading end of the member forces the syringe piston to urge the adhesive out of the nozzle.

The present invention includes a dispensing system for dispensing a packaged product, e.g. a condiment, onto one or more areas. A package including a pouch having the product therein cooperates with a dispensing gun to dispense a dose of product. In various aspects the invention includes a packaging system that includes a container and a flexible package; a package with a frangible seal, the package including a flexible pouch; a dispensing assembly for dispensing a product from the package; a dispensing gun system; a method of making a package; and a method of dispensing a product. The packaging system includes a container such as a rigid sleeve, and a flexible pouch positioned within the container interior, and also includes a valve that enables the product to exit the pouch interior and be dispensed. An optional diffuser coordinates with the valve to dispense product from one or more product outlets.
