A dispensing paintbrush includes a handle, a brush head connected to the handle, and bristles attached to the brush head to apply a fluid to a surface. A coupler is attached to the handle and is configured to connect to a fluid source. A nozzle is attached to the coupler and is configured to dispense the fluid to the bristles. The nozzle extends within the bristles and terminates at a position from the brush head that is less than one half the length of the bristles.

A station for covering a bread roll half of a bread roll with a sauce in a preparation line of a fast food restaurant, comprising: a table by which a user standing at a front side can cover a bread roll half with sauce, a container comprising the sauce and arranged over the table at a working distance from the front side and from which an outlet nozzle oriented towards the table protrudes at a vertical distance from the table, so that the bread roll half which is to be covered with sauce can be placed on the table below the outlet nozzle, and a pressure actuator that can be actuated by the user and which is designed to dispense the sauce from the container onto the bread roll half when actuated by the user.

A lowering mechanism for a hand held jacking tool comprises a caulking gun jacking mechanism. The lowering mechanism comprises a lowering plate on top of the holding plate, a pushing lever connected with a hinge attachment to the lowering plate at a rear end, wherein the pushing lever is pivoting around a pivot structure connected to the lever or holding plate a distance backward from the hinge attachment, causing the lowering plate to grip the jacking shaft when the lever is pushed downwards and then, in turn, pushing the holding plate downwards and loosening it from the jacking shaft and moving it down along the jacking shaft a distance determined by the pivoting action of the lever. The lowering plate is held in place by a spring biasing the lowering plate towards the holding plate.

A device is provided for assembling components of a mixing syringe for use in a dental procedure. For this assembly, the components of interest include a beak and a mixing tip for the syringe. Specifically, the device includes a top plate formed with a hole, and a support member for the top plate that maintains the hole at a predetermined height H above a surface when the device is placed on the surface. For an assembly operation, the beak is supported on the device with a portion of the beak inserted downwardly through the hole of the top plate. This also extends a gripping member of the beak upwardly above the top plate. A grab ring of the mixing tip is then pushed against the gripping member of the beak for their engagement with each other. They are then removed together from the device and engaged with the mixing syringe.

A cutter is configured to be mounted to a push rod of a caulking gun. The push rod includes a pushing portion for pushing a container containing a caulking material and a rear end portion opposite to the pushing portion. The cutter includes: an assembling portion, configured to be mounted at the rear end portion of the push rod;

and a cutting portion, connected with the assembling portion and including a cutting member. A caulking gun including the cutter is further provided.

The present invention provides a glue gun, comprising a movable handle and a fixed handle, wherein the movable handle is connected to fixed handle via a pivot pin shaft; the movable handle is further provided with an actuating member, and the actuating member is provided with an actuating part cooperating with a push member; and a spacing between the pivot pin shaft and the actuating part is sized to be switchable between two or more gears, such that the magnitude of the force applied by the actuating member on the push member is changed. The gear in the present invention can be adjusted to enable switching between a fast feed and a powerful feed, thereby enabling a user to make adjustment according to actual requirements.

The invention concerns a caulking gun for dispensing material comprising a stock, a cartridge keep, a push rod longitudinally moveably mounted in the stock provided at its one end with a plunger which engages the piston of a cartridge placed in the cartridge keep, a catch member placed on the push rod, a trigger coupled to the catch member via an axle and pivoting about a pivot point, means for varying the thrust output exerted on the push rod when pressing the trigger for a given strength exerted on the trigger, wherein the means for modifying the thrust output allow the displacement of the axle between at least a first position and a second position.

In order to provide a caulking gun which allows in a simple way to vary the thrust output either between fixed values or continuously, the trigger is provided on its upper part with a trigger bridge in which two long holes are provided and the means for varying the thrust output comprise a ratio bridge element which is put over the trigger bridge and trigger and which is linked to the trigger bridge via the axle which traverses the two long holes.

By displacing the axle either between fixed values or continuously, the thrust output can be varied between fixed values or continuously.

A container 10 for mixing and dispensing of material having a liquid receptacle 14 and a plunger 18. The receptacle 14 has a front portion 36 and the plunger 18 has a forwardly projecting sharp protrusion 42 having a shaft 72 which terminates in a sharp outer end 78, 82. Upon the plunger 18 being depressed the sharp protrusion 42 pierces a front portion 36 of the liquid receptacle 14 and the liquid in the receptacle 14 is pushed hydraulically through the front portion 36 into the main chamber 17. Thus the liquid contacts material in the main chamber 17 to form a mixture. The plunger 18 can continue to be depressed so as to break the front portion 36 of the liquid receptacle 14 away and then push the material in the main chamber 17 towards a dispensing nozzle 26. The main chamber 17 has a frangible membrane 22 at a distal end 13 thereof which is hydraulically broken by pressure applied from the material in the main chamber 17 so that the material can be dispensed from the container 10. The container 10 is particularly envisaged for use with mixing and dispensing of dental materials.

A lightweight applicator system is provided for efficient extrusive dispensing of work material from a cartridge. A body of the system includes handle and cartridge frame portions. The handle portion defines a hub structure, which includes at least first and second retention structures. The cartridge frame portion includes a cage member configured for receiving a cartridge of work material, and is releasably coupled to the hub structure in revolvable manner First and second accessory tools are coupled respectively to the first and second retention structures in detachable manner A drive portion is operably coupled to the body, and includes a drive member passing displaceably into the cartridge frame portion for forcing extrusion of work material therefrom. The handle and cartridge frame portions of the body are formed of one or more predetermined nonmetallic materials.
