A device (1) for introducing a plugging compound (20) into a borehole (21), the device having a sleeve (2) with a cavity (3) for receiving the plugging compound (20). On one side, the sleeve (2) has a discharge opening (5), corresponding to the cavity (3), for discharging the plugging compound (20), and a support section (7), projecting laterally from the sleeve, for providing a support option for the sleeve (2) during introduction of the plugging compound (20). On the opposite side of the sleeve (2), an upper opening (4) is provided, through which a piston (16) together with a feed plate (18) protrudes into the cavity (3). The piston (16) is movable relative to the sleeve (2) in such a way that the feed plate (18) can be displaced in the cavity (3), for example to allow the plugging compound (20) to be received and dispensed.

A handheld applicator for delivery of post-treatment coating following application of a conversion coating includes a first vessel extending longitudinally and containing Socosurf PACS solution, a second vessel extending longitudinally and containing hydrogen peroxide, a pH indicator contained in one of the first or second vessels, a mixing region configured to combine the Socosurf PACS solution, hydrogen peroxide, and pH indicator.

A compound delivery applicator comprising a substantially conical portion comprising a first end configured to couple to a compound receptacle and an applicator blade coupled to the substantially conical portion. The applicator blade comprises a first portion extending outwardly along a longitudinal axis of and from a second end of the substantially conical portion, the first portion comprising a first side edge and a second side edge each forming an acute angle relative to the longitudinal axis of the substantially conical portion and a scraper coupled to the first portion distal the substantially conical portion. The compound delivery applicator further comprises a compound delivery channel extending internally through at least a portion of the substantially conical portion, the compound delivery channel further extending through the scraper of the applicator blade and configured to pass a compound therethrough.

Implementations of an applicator syringe are provided. In some implementations, the applicator syringe may be configured to dispense a lubricant from a dispensing needle thereof. In some implementations, the applicator syringe may be configured so that the plunger shaft and the dispensing needle are removable when not in use. In some implementations, when the applicator syringe has been disassembled, the dispensing needle may be stored within the barrel of the applicator syringe and the plunger shaft secured about the exterior of the barrel. In some implementations, the applicator syringe may comprise a barrel having a finger flange, a plunger positioned within the interior chamber of the barrel, a plunger shaft configured to urge the plunger forward, a dispensing needle that can be removably secured to the front end of the barrel, a removable cap, and a barrel plug.

A device for dispensing a material has a container for holding the material, a piston movably arranged within the container and a spindle in cooperation with the piston. The device is configured such that the spindle and the container are rotatable relative to each other to move the piston for dispensing the material. The piston and the spindle are adapted to anti-twist lock against each other in a first axial position of the piston relative to spindle. And in a second axial position of the piston relative to spindle the anti-twist lock between the piston and the spindle is suspended. The device helps minimizing any residual dental material upon attempting to empty the device.

A compound applicator includes a nozzle assembly including a nozzle opening and a plug movable relative to the nozzle opening between a first position in which the nozzle assembly is in a closed state, and a second position in which the nozzle assembly is in an open state, a spring configured to bias the plug into the first position, a cylinder configured to receive and store a compound material, a main housing, a handle rotatable relative to the main housing, a pull rod having a first end coupled with the plug, and an input mechanism located at least partially within the handle and/or the main housing and configured to convert rotational motion of the handle into axial movement of the pull rod, thereby moving the plug from the first position toward the second position. The spring pulls the pull rod such that the pull rod is biased into tension.

A handheld applicator for delivery of post-treatment coating following application of a conversion coating includes a first vessel extending longitudinally and containing SOCOSURF PACS? solution, a second vessel extending longitudinally and containing hydrogen peroxide, a pH indicator contained in one of the first or second vessels, a mixing region configured to combine the SOCOSURF PACS? solution, hydrogen peroxide, and pH indicator.

A telescoping syringe suitable for use with medications and other flowable materials is presented. The telescoping syringe includes a one-way valve, a plunger, and a barrel. The valve includes a barrier, an outlet(s) through the barrier, and an annular extension extending from the barrier. The plunger includes an inlet(s) and a proximal wall fixed at one end of a first side wall. The valve directly contacts a distal end of the first wall so that an annular flange extending inward from the annular extension slidingly engages an annular groove along the first wall between first and second positions. The circumferential end of the first wall contacts the barrier in the first position to close the outlet(s). The circumferential end does not contact the barrier in the second position to open the outlet(s). A first reservoir is defined by the first wall, the proximal wall, and the valve. The inlet(s) permits gas to enter the first reservoir as fluid is transferred through the valve to a second reservoir. The barrel includes a second side wall with a nipple fixed to a distal wall at one end and an open end at another end. The plunger is extendable from and retractable into the barrel at the open end via slidable engagement between first and second walls. The second reservoir is defined by the distal wall, the second wall, and the valve.

A syringe assembly contains a fluid material, preferably two reactive fluid materials. The syringe assembly includes a syringe body having at least one barrel and a piston assembly movable within the barrel. An activatable plunger is in contact with the piston assembly effects dispensing movement of the piston assembly. The piston assembly includes an outer piston in sealed engagement with the barrel and an inner piston in sealed engagement with the outer piston. The inner piston is movable within the outer piston with and against the bias of a spring to maintain the inner piston in contact with the reactive material in the barrel upon thermal expansion and contraction of the reactive material.

A caulking gun includes a push disk, a push rod, an adhesive cartridge compartment, a trigger and a gun body; the trigger is hingedly coupled to the middle part of the gun body; the rear end of the push rod is outside the gun body and provided with a braking device; the front end is in the adhesive cartridge compartment through the gun body and provided with a push disk; a push piece for driving the push rod is mounted in the gun body; the front end of the push piece is provided with a return spring; the trigger is provided with a pin position switching device for adjusting the propulsion ratio by adjusting the contact position of the push piece; adjustment of different propulsion ratios enables the caulking gun to be multifunctional to meet the construction requirements of different adhesives.
