Abstract: A machine for the distribution of dough or a similar viscous material, comprising a hopper with an end plane along which a distribution head is driven sealingly, its first position causing an open connection with the outlet of the hopper. The distribution head comprises a movable expeller in a pressure chamber, so interacting during a second position of the distribution head, with a storage chamber, comprising a piston under pressure, that an accurately metered portion of dough is received under pressure in said storage chamber, this portion being expelled when the position of the distribution head changes.

Abstract: A disposable package dispenser comprises a replaceable, collapsible, prefilled package of the product to be dispensed, and includes a product discharge member and attachment structure for releasably attaching the package to a pressurizable dispensing container. The container includes a manually operable expansible chamber to pressurize the interior of the container and thus the collapsible product containing package to collapse the package and effect pressurized discharge of the product when the discharge member is operated.

Abstract: A spring actuated pump device is mounted on a container for fluid, the device including a pump chamber into which fluid from the container can flow, the spring forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a finger actuated discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable captive nut being swivelly mounted on the container against axial movement with respect thereto, the nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially in response to rotation of the nut relative to the container and cylinder structure to compress the spring and store additional fluid pressurizing energy therein.

Abstract: A device for dispensing fluids employs a manually actuated pump mounted in the neck of a conventional container. The pump includes a stationary piston and a shiftable cylinder which form a pump chamber. The piston includes a check valve which controls the fluid inlet to the pump chamber. The cylinder is spring biased in a direction which pressurizes the fluid in the pump chamber. An upwardly extending neck of the cylinder is exteriorly threaded and carries a discharge valve. A cap which fits over the container neck, cylinder neck and discharge valve has an internally threaded tubular portion which can be engaged with the thread on the cylinder neck. The cap can be turned with the threads engaged to lift the cylinder against the bias of the spring and draw fluid into the pump chamber. With the cap removed, the discharge valve can be opened to allow fluid in the pump chamber to flow through the cylinder neck and exit from the discharge valve.

Abstract: A housing has a compartment subdivided by a pair of sleeve valves into an input compartment to which is continuously fed a stream of viscous hardenable material and an output compartment arranged adjacent a transport device which step-wise advances a succession of containers. Each of these sleeve valves has a central piston and has a valve port that can be directed either into the input compartment or the output compartment. Thus one of the sleeves is turned with its port toward the input compartment and its piston is retracted to draw into the sleeve a predetermined quantity of the viscous mass. Thereupon the sleeve is rotated through 180.degree. and this portion is discharged into the output compartment and thence into one of the containers.
