A process for operating an extrusion system is provided. An extrusion device is provided that has at least two extrusion pistons operable with different feed ratios. The process involves storing a ratio of feed rates of the extrusion pistons in a storage device of the control device in dependence on the second signal. A least one drive device is actuated by the control device for displacing the two extrusion pistons into a start position, in which a plunger of the first extrusion piston substantially abuts the first cartridge of the cartridge device and a plunger of the second extrusion piston substantially abuts the second cartridge the cartridge device. The at least one drive device is actuated by the control device with a ratio of feed rates stored in the storage device of the control device for the extrusion pistons at user request.

A roll-up grout bag apparatus includes a dowel with a slot formed therethrough from an open end to a closed end thereof. A lever is engaged with the dowel at the closed end to facilitate rolling the dowel about an axis thereof. The slot receives a filling end of a grout bag and is rolled onto the dowel using the lever to urge grout within the bag to be dispensed from an opening at a narrow dispensing end of the bag. The apparatus may include a ratchet mechanism to engage the lever with the dowel.

Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

The invention discloses a sauce gun with replaceable pushing mechanism, including a gun body, a push rod with row teeth, a fixed handle with a cavity, a trigger handle and a pushing mechanism, wherein the pushing mechanism includes a function case detachably installed in the cavity, the external wall of the function case is provided with a first sliding groove, the first sliding groove is internally provided with a first connecting piece driven by the trigger handle, and the function case is internally provided with a front push rod lock rotatably connected to the first connecting piece, a rear push rod lock hinged with the function case through a second connecting piece, and a flexible device driving the front push rod lock and the rear push rod lock to match with the row teeth respectively.

A dispensing device is provided for storing and dispensing a flowable, viscous material. A cartridge is provided for storing the material and includes a tube, a movable cup member located within the tube, an end wall having a nozzle opening covered with a removable seal and a nozzle. The nozzle is removably held within the cup member during storage. The dispensing device is formed by inserting the cartridge within the actuator. The actuator comprises a barrel, a trigger, a handle, a plunger and a resilient detent. The movement of the trigger causes the plunger to push the moveable member forward. The detent holds the plunger in place maintaining the flow of material.

A discharge device that serves the purpose of discharging at least two components from a multiple cartridge. The discharge device has a housing, a threaded rod and an advancing element with an internal thread. The threaded rod engages in the internal thread of the advancing element such that the advancing element can be pushed forward in a distal direction by turning the threaded rod in relation to the housing. In the region of its distal end, the threaded rod has a taper. Formed on the housing, in the region of its distal end, is a holding element. The holding element has a laterally open clearance, and the threaded rod is pushed with its taper laterally into the clearance of the holding element such that the holding element fixes the threaded rod axially in the housing in the distal direction and in a proximal direction opposite thereto.

The present invention includes a dispensing system for dispensing a packaged product, e.g. a condiment, including a pouch (60) having the product therein cooperates with a dispensing gun (30) to dispense a dose of product. In various aspects the invention includes a packaging system that includes a container (40) and a flexible package (50) with a frangible seal (70), and a flexible pouch (60); a dispensing assembly (100) for dispensing a product from the package; a dispensing gun system; a method of making a package; and a method of dispensing a product. The packaging system includes a container such as a rigid sleeve, and a flexible pouch positioned within the container interior, and also includes a valve that enables the product to exit the pouch interior and be dispensed. An optional diffuser coordinates with the valve to dispense product from one or more product outlets.

A cartridge-based extrusion dispenser assembly includes a carriage configured to hold a fluid cartridge, and a flexible strip system coupled to a plunger and including a first flexible tape operably associated with a second flexible tape. Within the carriage, the first and second flexible tapes opposingly reinforce each other to establish a substantially rigid shaft member. An actuator assembly is configured to feed the first and second flexible tapes into the carriage to advance the plunger to engage the fluid cartridge and dispense fluid therefrom.
