A manually drivable device for the mixing of a pasty mixing ware from at least two fluid starting components comprising at least two cartridges having feed plungers; a mixing space to mix the starting components, mixing vanes being provided in the mixing space and mounted such that they can rotate; a lever rotatable about a pivot point operatable manually or a pin that can be shifted in longitudinal direction and operatable manually in order to operate the device; a gear connected to the lever or pin, and connected to the rotatable mixing vanes in the mixing space; and a facility for propelling the feed plungers such that the motion of the lever or pin drives the rotation of the mixing vanes in the mixing space and motion of the feed plungers into the cartridges. The invention also relates to a method for mixing fluid starting components using the device.

The present invention provides actuation mechanisms that incorporate a transmission assembly that allows the mechanisms to cause actuation of workpieces according to a plurality of transmission modes (e.g., at least one forward transmission mode and at least one reverse transmission mode) on demand. Motion, direction, and/or force can be controlled by selecting the corresponding transmission mode. The mechanisms preferably are trigger-actuated by hand (i.e., manually) to cause movement of a workpiece in a desired direction. Desired directions can be linear or nonlinear. The same hand used for trigger action can also be used to change transmission modes in many modes of practice, even while using substantially the same grip used for trigger actuation. In other instances, actuation can be automated rather than manual. Preferably, both actuation and witching among transmission modes can be accomplished with one hand, even while maintaining substantially the same grip that is used for actuation.

A fluid cartridge system and method of removing a closure assembly from a first cartridge and a second cartridge includes a first cartridge body and a second cartridge body. A neck projects from the first cartridge body with a first outlet of the first cartridge and a second outlet of the second cartridge. A first closure having a first plug is received within the first outlet and includes a first closure coupling element. In addition, a second closure having a second plug is received within the second outlet and includes a second closure coupling element. The first closure coupling element is configured to interlock with the second closure coupling element such that securing the first cartridge body against the second cartridge body also connects the first closure to the second closure. As such, the first and second closures form the closure assembly for being collectively removed by an operator.

A resiliently deformable member for use in an apparatus for dispensing a viscous material from a container, such as an apparatus consisting of a container for holding the viscous material and a dispensing gun. The resiliently deformable member has a relaxed state and a compressed state. In use, the resiliently deformable member applies a force between the container and the dispensing gun to modulate the flow of the material from the container.

A dual fluid cartridge assembly includes a cartridge, a flange, and a piston tube. The cartridge defines a channel and includes an flange. The flange defines a cavity that extends from a cavity opening to a cavity base. The cavity opening is positioned within the channel of the cartridge, and the cavity base is positioned external to the cartridge. The piston tube has an extended end, and is positioned at least partially within the channel. The extended end is positioned within the cavity.

A new and improved food warming appliance comprises a housing within which a multiplicity of elongated sanitary sleeves or cups are adapted to be removably mounted and within which cheese dispensing guns are adapted to be respectively disposed. Respectively surrounding each one of the elongated sanitary sleeves or cups is an elongated aluminum tube, and respectively surrounding each one of the elongated aluminum tubes is an elongated flexible foil tube which has a heating strip operatively associated therewith. To complete the assembly, a suitable elongated tubular insulation sleeve respectively surrounds each one of the elongated flexible foil tubes. In this manner, when the heating strips of the foil heaters are energized, heat is transmitted radially inwardly from the foil heaters, to the aluminum tubes, and then to the sanitary sleeves or cups for, in turn, heating the dispensing guns whereby, for example, the semi-solid cheese products, disposed within the cheese dispensing guns, are sufficiently heated to predetermined temperatures which not only melt the cheese products and provide the same with the requisite fluidity for easy and reliable dispensing, but also renders the cheese products safe for consumption. Still further, a food dispensing station is formed by the food warming appliance and the dispensing guns.

The present invention relates to a caulking gun for dispensing viscous material comprising a stock a cartridge keep a push rod longitudinally moveably mounted in the stock provided at its one end with a plunger which engages the piston of a cartridge placed in the cartridge keep, means for engaging the push rod to advance it, brake means hinged to the stock and provided with a clearance hole for engaging the push rod such that the push rod is moveable in a direction advancing the push rod towards the cartridge and is held in a direction retreating the push rod from the cartridge, which brake means are arranged to travel to a first position relative to the stock as the push rod advances and to a second position as the push rod retreats thereby defining the retreat of the push rod, the brake means being inclined relative to the axis of the push rod and adjusting means for varying the retreat of the push rod. In order to provide an adjustable caulking gun with at least two different levels of retreat of the push rod giving the user easily a visual feedback of the chosen retreat of the push rod, it is proposed according to the present invention that the adjusting means are configured as a rotatable wheel with a slope, the rotatable wheel being positioned on the axis of the push rod between the stock and the brake means, the distance between the highest point of the slope and the brake means defining the retreat of the push rod. This rotatable wheel allows the user to select the level of retreat of the push rod by turning the wheel between a first position with no retreat of the push rod and a second position with a maximum retreat of the push rod resulting in a anti-drip behavior of the caulking gun.

The present invention is a material dispensing system for controllably dispensing material from a packaging such as a chub pack. The system can include a housing capable of receiving the packaging, a cover pivotably connected to the housing, at least one nozzle tip, and at least one piercing projection capable of piercing the packaging. A packaging compression assembly can be used to compress the packaging toward the piercing projection so that the piercing projection pierces the packaging and allows the material in the packaging to be dispensed from the nozzle tip. A locking slide can be included to secure the cover in a closed position.

A nozzle is provided configured for applying sealant to a construction panel joint. The nozzle includes a nozzle body having a first, supply end, and a second, outlet end opposite the supply end, the body defining an internal passageway. Also included on the nozzle is at least one tooling formation located at the outlet end and constructed and arranged for tooling a bead of sealant dispensed out the passageway from the outlet end.

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.
