This invention relates to a discharge device of the dispenser gun type, which is suitable in particular for discharging semi-solid materials such as e.g. bone replacement materials. The discharge device comprises an adapter (400) which is removably attached to a main body (110) of the discharge device. A fastening structure for attachment of a container (300) is formed on the adapter substantially along a proximal direction (C) contrary to the feed direction (A). As a result various types of containers can be fastened to the machine without the need to change the mechanism of the device. The container can be provided on both ends with identical external threads and can be closed by closure caps in order to enable intuitive handling. In order to improve access to points which are difficult to reach, the container may be in the form of a curved pipe or may be formed flexibly. The piston rod (200) of the discharge device is then also formed flexibly.

A method for dispensing fluid from a fluid dispensing apparatus. The apparatus may include a housing, wherein the housing may include a motor, and wherein the motor may be configured to be operatively connected to a power supply, wherein the motor may be further configured to be operatively connected to one or more drive rods, wherein the one or more drive rods may be configured to engage a fixed lead screw with a triangular nut, and wherein the drive rod may be further configured to engage at least two pistons of a fluid cartridge. The housing may include a controller configured to be operatively connected to the power supply, the controller may be configured to generate a pressure within the fluid cartridge by adjusting, via the motor, the drive rod and piston in a first direction relative to the fluid cartridge to dispense fluid in the fluid cartridge.

An adhesive dispensing device includes a dispensing tube, a dispensing needle fixed to a bottom end portion of the dispensing tube and configured to dispense adhesive received in the dispensing tube, a heating sleeve surrounding the dispensing needle and configured to slide along a length of the dispensing needle and heat the dispensing needle, and a driving assembly. The driving assembly drives the heating sleeve to slide along a length of the dispensing needle to reveal an end portion of the dispensing needle or cover the end portion of the dispensing needle.

An integrated multicomponent dispensing system for use with a fluid dispenser and associated methods of manufacture, such as by 3D printing are provided. The system includes a cartridge including first and second cylinders having first and second chambers for storing first and second fluid components, respectively, and first and second fluid outlets. A static mixer of the system includes a fluid passageway and a plurality of mixing baffles configured to mix the first and second fluid components upon delivery into the fluid passageway. A frangible closure may also be formed integral with the cartridge and/or the static mixer to prevent discharge of the fluid components into the static mixer until this is desired. The formation of the static mixer and optionally also the cartridge as an integral, unitary piece reduces cost of assembly and storage of multiple parts conventionally formed separately.

A confinement structure and an actuation member that provides a system that allows for controllable deformation of a variety of containers are disclosed. In one embodiment, the system of the present disclosure provides for controllable deformation of a container such that a portion of the container acts as a wiping means to empty a substance from the container. A container that includes an indentation formed on a first end of the container and a container opening located at a second end of the container is also disclosed. In one embodiment, with the container deformed to a final position, the indentation fits inside the container opening to completely expel a substance from the container.

According to embodiments of the invention, apparatuses and devices are provided for a liquid compound dispensing device. Generally, the dispenser includes a frame for carrying a composition, a plunger shaft having a piston at one end for urging the composition out of the frame, and one or more plunger driving assemblies for driving the actuator shaft to expel the compound. The plunger driving assemblies may have one or more downwardly extending handles, and the assembly includes one or more triggers extending upwardly within the housing. One or more triggers may be pressed to expel compound. Further, one or more triggers and/or handles may be movable to different portions of the dispensing device.

A paste application device stores two starting components for mixing the starting components to form a paste and for application of the formed paste. The device comprises a two-component cartridge comprising two internal spaces, two feed plungers shiftable in the internal spaces and bordering the internal spaces on a first side of the two-component cartridge, and at least two dispensing openings by means of which the internal spaces are open on a second side of the two-component cartridge that is opposite from the first side. The device further comprises a hollow cylinder that is made of a plastic material and has one front face that is open and one front face that is partially closed, in which is situated an axially mobile plunger that has at least two pestles attached to it, wherein the at least two pestles are oriented in the direction of the open front face, wherein the open front face of the hollow cylinder is arranged to axially touch against the first side of the two-component cartridge, and a connector for a compressed gas cartridge extends through an opening in the pressure vessel wherein a flap valve can be used to regulate the volume flow of the starting components through the dispensing openings, and whereby the flap valve is operable by means of a rod assembly of the paste application device, whereby the rod assembly is supported with a clearance of at least 0.3 mm in at least one direction that is perpendicular to the main direction.

A caulking gun includes a stock having a handle, a piston rod slidably attached to the stock and movable forwardly and rearwardly relative to the stock, the piston rod includes a front portion, and a plunger attached to the front portion, the plunger including a head attached to the front portion, and the plunger including a pusher having an opening formed in an upper portion of the pusher for receiving and engaging with the head and for securing the head to the pusher. The pusher includes an inner peripheral channel formed in the upper portion and communicating with the opening of the pusher for receiving and engaging with the head. The pusher includes a spring latch on the upper portion for engaging with the head and for locking the head to the pusher and for preventing the pusher from being disengaged from the head.

According to embodiments of the invention, apparatuses and devices are provided for a liquid compound dispensing device. Generally, the dispenser includes a frame for carrying a composition, a plunger shaft having a piston at one end for urging the composition out of the frame, and one or more plunger driving assemblies for driving the actuator shaft to expel the compound. The plunger driving assemblies may have one or more downwardly extending handles, and the assembly includes one or more triggers extending upwardly within the housing. One or more triggers may be pressed to expel compound. Further, one or more triggers and/or handles may be movable to different portions of the dispensing device.

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.
