A control method of an electromechanical apparatus (10) for installing a plunger tip (31) in a syringe (21), the control method comprising: providing a syringe (21) with at least one opening (22); providing a plunger tip (31) configured for snug insertion in the opening (22); pushing the plunger tip (31) inside the syringe (21), by a pusher rod (60) of the electromechanical apparatus (10), the plunger tip (31) passing through an intermediate cannula element (50); monitoring over time a force exchanged between the plunger tip (31) and the pusher rod (60), providing a force signal (401, 402, 403, 404) by a force detector (61) of the electromechanical apparatus (10); analyzing the force signal (401, 402, 403, 404) to determine an installation status of the plunger tip (31) in the syringe (21).

A reversible and reusable caulk dispenser for use with a caulk gun. The caulk dispenser has a tubular cartridge with a plunger inside the cartridge near a first open end of the cartridge and an end cap with a nozzle that can be attached at an open second end of the cartridge. A foil packet of caulk or sealant material is inserted in the cartridge of the dispenser. A closed end of the packet is positioned adjacent the plunger while an open end of the packet is at the end of the cartridge where the end cap is attached. The dispenser is used in a standard caulk gun and the caulk material expelled through the nozzle as the caulk gun is operated. When the packet is emptied the dispenser can be reused with a new packet inserted and the end cap attached now to the opposite end of the cartridge.

A coaxial cartridge for multi-component materials includes a head part having an outlet, an inner tube forming a first storage compartment configured to store a first component inner tube forms part of the outlet, and an outer tube. The inner tube is arranged within the outer tube at a longitudinal axis that is common to both the inner tube and the outer tube. A space formed between the outer tube and the inner tube forms a second storage compartment configured to store a second component. The outer tube forms a further part of the outlet.

A hand-held lubrication device that allows for both one- and two-handed operation. The device utilizes a front-facing mounted trigger that actuates a rear-mounted plunger via two tie rods.

The invention relates to a tool (1) for applying liquid agent such as, for example, an insulating foam, an adhesive, or paint to the mantle surface of a circular-cylindrical object (10), comprising a tool head (2) having an axially through hole (3) with a substantially circular cross-section. The tool head (2) comprises an inner flange (8), an outer flange (16), a distribution chamber (12) running around the inner flange (8) and that comprises at least one outlet (13; 23; 33) distributed around the through hole (3). An asymmetrical restriction is arranged at the outlet (13) so that the outlet is restricted where the pressure is as highest (14). The invention also relates to a method for applying an agent around a circular-cylindrical object (10) with the tool (1).

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 dispenser (10) for dispensing a flowable material M has a container (12) having an outer wall (20) and membrane (14) collectively defining a first chamber (22) configured to contain the flowable material M. The membrane (14) has a thickness and a weld seam (40) wherein the weld seam (40) has a thickness less than the thickness of the membrane (14). A fracturing mechanism (16) is operably connected to the container (12). The fracturing mechanism (16) has an extending member (64) projecting from the outer wall (20) of the container (12). The extending member (64) has a projection (66) positioned proximate the membrane (14), wherein in response to deflection of the extending member (64), the projection (66) deflects the outer wall (20) proximate the membrane (14) wherein the weld seam (40) fractures creating an opening (41) through the membrane (14) configured to allow the flowable material M to pass therethrough and from the dispenser (10).

A handheld device, in particular a cartridge press and/or tubular bag press, for dispensing filling material into a joint, including: a handle assembly for manually gripping the handheld device and for moving the handheld device along a joint path, a dispensing device for dispensing the filling material into the joint, and a sensor device which is designed to detect an influencing quantity. The influencing quantity influences the body geometry of a filling material body formed by the filling material dispensed into the joint, in which the handheld device is adapted to adjust a dispensing rate (r) at which the dispensing device dispenses the filling material based on the detected influence quantity.

A cutter and a caulking gun having the same are provided. The cutter is configured to be connected to a caulking gun having a connecting member which is disposed on the caulking gun and includes a first assembling portion. The cutter includes a main body including a base and a cutting portion connected with the base, the cutting portion includes a cutting blade, and the base includes a second assembling portion configured to be detachably connected with the first assembling portion.

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.
