Sealant dispensing cartridge assemblies including radially expandable collets are disclosed. A plunger head assembly includes a ram head attached to a plunger rod. As the plunger rod is advanced into the sealant cartridge, the ram head presses against a rear side of a movable plunger against an opposing force created by a sealant contained in the cartridge on a front side of the plunger. As the plunger rod is further advanced, the collet contacts the ram head and radially expands against the inner sidewall of the plunger. The resulting radial force presses the sidewall of the plunger against the inner surface of the cartridge to thereby reduce or prevent unwanted leakage of the sealant around the plunger.

An apparatus for capping the tip of the nozzle of a caulking tube retained in a caulking gun to prevent the caulking tube from leaking caulking material such as latex or silicone during non-use. The apparatus has a cap portion, a housing portion, and a retractable flexible cord to provide a retractable cap to be used with the caulking tube placed in a caulking gun to prevent leakage when the caulking gun and caulking tube are not in use. The housing contains a retraction member which is placed under force when the cap is pulled away from the retraction member and placed over the tip of the caulking tube nozzle. When the cap is removed from the caulking tube nozzle, the tension from the retraction member causes the flexible cord to pull the cap to a location adjacent the housing so that the cap can be easily retrieved and not lost.

A dispenser includes a housing, a push rod, and a push rod driving mechanism. The push rod is moveable relative to the housing. The housing has at least two housing parts and is configured to receive at least a portion of the push rod driving mechanism to move the push rod relative to the housing. The at least two housing parts are held together by the push rod.

A universal caulking gun and method of converting a standard caulking gun into a universal caulking gun are disclosed, along with a kit of parts for converting a standard caulking gun into a universal caulking gun. The universal caulking gun that is capable of accommodating both small and large caulking tubes. It includes a combination of small and large plunger members that are configured to be removably attached to the caulking gun rod. The small and large plunger members are sized and configured to nest together and form a single plunger unit corresponding to the internal diameter of a large caulking tube. Alternatively, the small and large plunger members are separable such that the single plunger unit corresponds to the internal diameter of a small caulking tube and the large plunger can be retained in a non-functional position.

Sealant dispensing cartridge assemblies including radially expandable collets are disclosed. A plunger head assembly includes a ram head attached to a plunger rod. As the plunger rod is advanced into the sealant cartridge, the ram head presses against a rear side of a movable plunger against an opposing force created by a sealant contained in the cartridge on a front side of the plunger. As the plunger rod is further advanced, the collet contacts the ram head and radially expands against the inner sidewall of the plunger. The resulting radial force presses the sidewall of the plunger against the inner surface of the cartridge to thereby reduce or prevent unwanted leakage of the sealant around the plunger.

The disclosed device is an adapter to an existing caulking methodology. The adapter is configured to perform the activity of protective taping, scraping and cleaning of excess compound to occur simultaneously with caulking. The disclosed adapter removably attaches to cannister holding cradle of a calking gun. At least one front roller presses a strip of tape against a side of an area being caulked or finished, with tape being drawn from a tape roller in back of the front roller.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.

A device for applying adhesive and/or sealant having a housing for receiving a container, said housing having the following: a receiving chamber for receiving the container; a closable application tip which is connected to the receiving chamber and through which the adhesive and/or sealant can be discharged; a stable casing for the receiving chamber; at least one region of the housing which is in the form of a deformable pressure region and which allows pressure to be exerted from the outside onto the container which can be placed in the receiving chamber.

The present invention relates to a pneumatic glue gun including tank components which contain a glue hose and an injector head; pressure generating units which contain a shell, an extruder, a slidable piston and a push/pull rod; and a drive component connected with the extruder. The tank components are fixed on the shell through a open end of the glue hose and faced the interior space of the shell. The drive component increases the atmospheric pressure between the extruder and the piston by driving the movement of the extruder in the shell, and the piston slides in the glue hose through the increased atmospheric pressure. The glue of the present invention does not need to be replaced, and the glue can be replenished at any time, so the work of replacing the tank is eliminated, and no waste of resources is caused.
