Metering dispensers include a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.

A fluid container press including a receptacle for a fluid container, a pressing device for pressing the fluid container and for locking the fluid container in the receptacle, a carrying handle, and a stabilizing handle with which the fluid container press can be gripped and stabilized with a second hand of the user while the user grips the carrying handle with his first hand. The fluid container press includes an actuating element operable by the user to release the locking of the fluid container in the receptacle so that the fluid container can be removed from the receptacle, in which the stabilizing handle is the actuating element or the actuating element is arranged in the region of the stabilizing handle so that the user can actuate the actuating element with his second hand while the user grips the stabilizing handle with his second hand.

A system for dispensing curable material. A lead screw is rotatably fixed relative to a first control surface and includes external threads. A locking nut includes internal threads threadably engaging the external threads. An engagement feature of the locking nut is adapted to be selectively engaged with an actuator having a second control surface. The threads provide for rotation of the locking nut about a translation axis when the actuator is in a disengaged position. Rotation of the locking nut permits the lead screw to move proximally along the axis and the compressed curable material to at least partially decompress within a dispensing volume. The threads further provide for distal advancement of the lead screw along the axis when the actuator is in an engaged position rotatably fixing the locking nut about the axis. Methods for operating and packaging the curable material dispensing system are also described.

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 device comprises a compartment for receiving a dental material, a piston for extruding the material from the compartment and a spindle drive for moving the piston and the compartment relative to one another. The spindle drive comprises a spindle and a link which are adapted for disengageable engagement with one another, wherein the spindle and the link are operable relative to each other between an engaged position in which the link and the spindle are engaged with one another, and a disengaged position in which the spindle and the link are disengaged from one another. The device may be relatively robust and inexpensive to manufacture, and may facilitate preparation of dental materials for use.

An apparatus adapted for dispensing flowable viscous batter has a housing, a barrel removably connected to the housing and a cap removably connected to the barrel. The housing contains a drive mechanism, a dual-position gearbox and a motor. The motor is in communication with the dual-position gearbox, which is in communication with the drive mechanism. The drive mechanism engages a threaded rod that is slidably disposed within the barrel. The threaded rod is attached to a piston that is non-rotatably positioned within the barrel. The drive mechanism actuates the threaded rod such that the piston is advanced or retracted in the barrel when power is supplied to the motor. The operating position of the gearbox determines whether the piston advances or retracts in the barrel when power is supplied to the motor. The cap includes a dispensing nozzle configured to regulate the flow of viscous batter from the barrel when the piston advances in the barrel. The cap also includes a piping spacer that facilitates consistent spacing and dispensing of batter on a baking surface.
