A caulking gun includes a gun body, a swinging member, a push rod, driving member and an abutting member. The gun body includes a side wall. The side wall has a penetrated portion. The penetrated portion defines an axial direction. The swinging member is swingably disposed on the gun body. The push rod is axially movably, disposed through the penetrated portion and the swinging member. The driving member is movably disposed in the gun body, and the driving member and the swinging member are located at two sides of the side wall respectively. The push rod is frictionally drivable by the driving member. The abutting member is axially movably disposed through the penetrated portion. The abutting member is disposed circumferentially around the push rod less than 360 degrees. Two ends of the abutting member are axially abuttable against the driving member and the swinging member respectively.

In some examples, a medical dispensing device includes a housing and a trigger. A first engager of the device is configured to move axially as the trigger pivots. As the first engager moves, it engages a rod. A maximum proximal position of the rod is defined by a stop. A spring presses the first engager into the trigger such that either the trigger or the first engager rests against a stop limiting rotation of the trigger. A second engager moves axially as the trigger pivots. At the actuated position the second engager, defined by a stop, the second engager limits proximal movement of the rod. An assembly transfers movement of the trigger to the second engager after the trigger has pivoted a threshold amount. A member of the assembly distally moves the second engager. Until it is at the actuated position, the second engager enables the rod to proximally move.

A dispenser for dispensing materials includes a dispenser body, a driving rod movable relative to the dispenser body and into the receptacle, a trigger lever having an actuation member for displacing the driving rod upon rotation of the trigger lever around a rotation axis, and a pivot member that rotatably connects the trigger lever to the dispenser body and defines the rotation axis. The pivot member is movably connected to the trigger lever such that a lever distance between the rotation axis and the actuation member changes upon movement of the pivot member relative to the trigger lever. The dispenser includes an adjustment mechanism for adjusting a mechanical advantage of the trigger lever by changing the lever distance and to adjustably fix the lever distance to at least a minimum distance and a maximum distance.

An applicator for ejecting doses of a flowable component includes a housing, an application tip connected to the housing, an actuation mechanism, and an insert which is detachable from the housing. The insert is adapted to be inserted into the housing, and has a storage volume for the flowable component. The housing includes a receiving portion adapted to the insert. The insert includes a drive portion which is adapted to cooperate with the actuation mechanism so that the operation of the actuation mechanism results in a displacement of the insert relative to the housing and on a displacement axis.

This invention is a gun shaped device used in the application of caulk, paste and or other semi solid high viscosity fluids. The device contains a barrel portion for the tube to be inserted into, and a plunger portion with a flat round metal piece with a fitting that attaches to a set of shortened rods. The set of shortened rods acts as a plunger and goes through a guide toward the back of the handle. The barrel can be shortened for use of smaller tubes of caulk.

A two-component dispenser includes first and second push rods guided within the two-component dispenser, first and second drive plate assemblies respectively associated with and embodied for engaging with the first and second push rods, and an actuation mechanism symmetrically arranged with respect to the first and second push rods and with respect to the first and second drive plate assemblies. The actuation mechanism displaceable in a linear manner between a release position and a plurality of dispensing positions and engaging the first and second drive plate assemblies in the dispensing positions to lock the first and second push rods by engagement with the first and second drive plate assemblies and to entrain the first and second push rods in a dispensing direction of the two-component dispenser.

A condiment dispensing device is provided that, when activated by a user, may expel a condiment from a condiment cartridge secured within the condiment dispensing device. The condiment dispensing device includes a recess at its bottom portion in which a dampener member may be secured. When the dampener member is secured in the recess, the bottom portion of the dispensing device is flat, which results in the device being orientation within a holder in a consistent and predictable fashion. Because the dampener member may be made of a rubber or soft plastic, when the condiment dispensing device is placed in the holder, substantially less impact and noise are created than if the dispensing device were construed entirely made of metal.

A heat pump dispenser includes a housing having a handle portion and a barrel portion. A feeder section is coupled to the handle portion. The feeder section includes a feeder mechanism and a dispensing trigger assembly operably coupled to the feeder mechanism. The feeder mechanism includes a gear assembly having a drive gear operably engaged to a plunger housed in the barrel portion. The trigger assembly includes a trigger having a ratchet portion. The ratchet portion selectively engages and rotates the drive gear to move the plunger toward a dispensing opening provided in the barrel portion and into engagement with an adhesive/filler stick. The feeder mechanism is selectively actuated by the dispensing trigger assembly to advance the adhesive/filler stick into a heater section of the barrel portion.

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.
