A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. An alternative embodiment includes a lockable, compressible gas spring. Another alternative embodiment includes a rotating element driven by a reversible motor mounted on the handle assembly. The rotating element drives a discharge mechanism in a discharge direction of rotation, and reloads the reservoir in a reload direction of rotation. Multiple alternative embodiments of linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism.

A device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. The device comprises: a nozzle for dispensing the third material; a first container adapted to store a first ingredient material and mix the first ingredient material with a second ingredient material; a second container disposed within the first container, and moveable between a storage position in which a second ingredient material is stored in the second container and a mixing position in which the second ingredient material is moved to the first container; a mixer that longitudinally extends into the first and second containers; a handle alternatively coupled to the mixer to mix the first and second ingredient materials or to the second container to move the second container to a dispensing position to dispense the third material. During use, the first container is rotated causing the second container to move relative to the first container and the second material to flow into the first container for mixing. After mixing, the handle is uncoupled from the mixer and coupled to the second container to dispense the third material from the nozzle. Embodiments are also described herein for a method of making the device and a method of using the device.

A guide tool device for an optical fiber or cord includes a tool base that mounts on an adhesive syringe. A cord guide head has a flat leading edge, a key removably insertable into a keyway in the tool base, a guide channel for guiding a fiber toward the leading edge, and a tube for receiving an adhesive. An opening in the guide channel communicates adhesive from the tube into the channel, for applying the adhesive along a fiber while it is guided toward the leading edge on the guide head. A fitting is arranged to connect in sealing relationship with a distal end of the syringe, and a flexible tubing is connected between the fitting and the other end of the tube on the cord guide head. When urged toward the distal end of the syringe, the adhesive is communicated into the guide channel in the cord guide head.

Stands for glue and other applicators are described. The stand may include a seal that allows a user to place the applicator nozzle in the hollow interior of the receptacle without the cap without fear of the liquid in the nozzle clogging or drying out.

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.

A sealant discharging nozzle includes a nozzle body, a flat surface, a nozzle positioning portion, and a locating pin. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The nozzle positioning portion includes a pair of tapered surfaces disposed on both sides of the flat surface in a width direction of the flat surface. The locating pin is formed between the pair of tapered surfaces.

A manifold having a first side, a second side, a first channel extending from the first side to the second side, and a second channel extending from the first side to the second side is disclosed. The first channel and the second channel each define a linear longitudinal axis. In one embodiment, the first channel longitudinal axis and the second channel longitudinal axis are oblique to the first side and the second side of the manifold. The manifold of the present disclosure provides channels that can be easily cleaned and allow for an increased flow performance.

According to examples, an injection gun may include a filler material injection assembly. The filler material injection assembly may include a pressure regulator handle to control a flow of filler material, a four-way valve, a pressure gauge, a pressure release valve assembly, and a first output coupling. The four-way valve may be connected to the pressure regulator handle. A first port of the four-way valve may be connected to the pressure regulator handle to receive the filler material under pressure. The pressure gauge may be connected to a second port of the four-way valve to indicate a level of pressure of the filler material under pressure. A pressure release valve assembly may be connected to a third port of the four-way valve. The pressure release valve assembly may reduce the level of pressure of the filler material under pressure. A first output coupling may be connected to a fourth port of the four-way valve to eject the filler material under pressure.

An improved hot melt glue gun with an automatic glue stick feeding structure includes a housing that is gun-shaped and that includes an inlet and an outlet. A glue stick feeding module is mounted in the housing and located adjacent to the inlet. The glue stick feeding module includes a motor connected to a casing. The casing includes a passage and a through-hole. The passage is located in the casing and intercommunicates with the inlet. The through-hole is aligned with the passage in a transverse direction. An activation module includes an activation rod reciprocatingly and movably extending through the through-hole. A micro switch is located adjacent to the activation module and is electrically connected to the motor. The micro switch is configured to be pressed by the activation rod to activate the motor. A hot melt module is mounted in the housing and located adjacent to the outlet.
