A caulking gun includes is provided, including: a gun body, a cartridge sleeve, two push rods, a driving member, a lever and a switch mechanism. The cartridge sleeve is rotatably connected to the gun body and configured to receive two sealants. The two push rods are movably disposed on the gun body. The driving member is movably disposed on the gun body and drives the two push rods to move. The lever is swingably disposed on the gun body about a pivot center and includes an abutting portion which is abuttable against the driving member. The switch mechanism is disposed between the gun body and the lever and includes a switch member being movable between a first position and a second position.

A dispensing device for dispensing a viscous material from a cartridge received in the device includes a main housing, a front support, a rear plunger assembly, a motor, and gear assembly. The rear plunger assembly is spaced apart from the front support by an elongate member. The rear plunger assembly includes a plunger plate supported in a plunger housing above a cutting edge. The rear plunger assembly is rotatable about an axis parallel to the longitudinal axis of the elongate member. The motor and gear assembly are disposed in the housing and are engageable with the elongate member to move one of the front support and the rear plunger assembly toward each other, thereby urging the cutting edge of the rear plunger assembly against an edge of the cartridge as the plunger plate is driven against the cartridge to expel the viscous material from the cartridge.

An automatic gluing machine includes an automatic gluing mechanism. The automatic gluing mechanism includes a sleeve, a pushing component mounted to the sleeve, an assembling head, and a driving module including a gear module. The sleeve is equipped with a first sleeve gear. The pushing component includes a rotating body and a first rotary gear. The assembling head is assembled inside the sleeve. The gear module cooperates the first rotary gear to drive the rotating body to rotate bidirectionally. The gear module cooperates with the first sleeve gear to make the sleeve to rotate in a single direction. A rotation speed difference between the first rotary gear and the first sleeve gear is generated, so after every rotation of the assembling head, a single-direction rotation displacement of the assembling head is generated relative to a last rotation of the assembling head.

A dispensing apparatus for a flowable component includes a storage container having a storage chamber for the reception of the component, a filling opening and a dispensing opening. A piston is displaceably arranged within the storage container in the direction of an expulsion direction. Moreover, dispensing apparatus includes an actuation element by which the piston can be displaced stepwise in the direction of the dispensing opening. After release of the actuation element actuation element is displaced from a final position into a starting position by a spring.

A driving device of a metering and mixing apparatus for multi-component substances is disclosed, which driving device can have at least two cartridge holders for holding interchangeable cartridges with individual substance components, a discharging apparatus for simultaneously discharging the substance components from the cartridges through component outlets with the aid of discharging pistons entering the cartridge holder or cartridges, and a mixing apparatus which is connected to the component outlets, for mixing the discharged substance components and discharging the latter in mixed form, and a transmission unit for the connection of a drive motor, wherein the transmission unit can have a detector for detecting at least one counter pressure which builds up during the discharging of at least one of the substance components, and a controller, which is connected on an inlet side to the detector for bringing about a driving control function in response to a detection result.

An applicator for delivering an application liquid fed from a reservoir, from a delivery port to an outside by way of an interior space of an application body, includes a spacer inserted in the interior space of the application body. In this applicator, a clearance between an exterior face of the spacer and an interior face of the application body forms a communication passage for flowing the application liquid, and the application liquid is delivered from the delivery port by way of the communication passage.

An improved fluid dispensing device for cooking uses is presented, comprised of a clear glass tube with a silicon ball advanced by a threaded rod. The silicon ball in the tube provides a secure seal to prevent leakage and loss of valuable oils and extracts during dispensing.

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.
