A cartridge in which a pipe can be retained without increasing the number of components or suppressing pushing-out of a content. A length L over which the outer peripheral surface of a pipe and the inner peripheral surface of a through hole contact each other when the pipe is press-fitted into the through hole, an average outside diameter R of the pipe in the range of the length L over which the pipe is press-fitted into the through hole, and an average inside diameter N of the through hole in the range of the length L are determined to meet: LR(1N/R)3.3W and 0.01<(1N/R)<0.1, wherein the maximum pushing load of the piston is defined as W and a grasping force to hold the pipe as the pipe is press-fitted into the through hole is defined as 1N/R.

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.

An applicator for and method of applying a material, and a piston assembly for the applicator. A piston assembly of the applicator is movably engaged within a housing to form a reservoir that is expandable and contractable to, respectively, draw into and push out from the reservoir the material via an opening during, respectively, suction and pressure phases of the applicator. The piston assembly includes an outer seal to prevent ingress of fluid towards the reservoir from an outer side of the piston assembly during the suction phase and an inner seal disposed between the outer seal and the reservoir to prevent egress of material out of the reservoir into a cavity formed between the housing and the inner and outer seals, during the pressure phase. The outer seal moves freely as the applicator is moved to the pressure phase to open the cavity for pressure equalization to prevent suction.

A dispenser for dispensing materials stored inside a cartridge includes a support sleeve, a receiving space to receive a cartridge in the support sleeve, a piston connected to a piston driving mechanism moveable through the receiving space to urge a material stored in the cartridge along a dispensing axis towards an outlet of the cartridge to dispense the material, a handle including a trigger to activate movement of the piston driving mechanism along the dispensing axis, the receiving space being formed by a frame, with the frame being configured to hold the support sleeve during dispensing, and the receiving space including a pivot mechanism to act between the frame and the support sleeve such that the support sleeve is capable of pivoting about a pivot axis aligned perpendicularly to the dispensing axis from a first position to a second position, and vice versa.

A compact drive mechanism for converting rotary motion to linear motion comprising a casing, gearbox, and beam coupled to the casing and gearbox, wherein the gearbox advances along the casing and the beam extends out from the casing simultaneously in response to rotary input to the gearbox. In its preferred embodiment, the invention comprises the drive mechanism incorporated into a handheld viscous material dispenser, wherein the beam further comprises a plunger face which acts on a viscous material cartridge, such as a caulk cartridge, to eject the viscous material from the cartridge.
