Abstract: A device for measuring and dispensing quantities of free flowing material. The device is a tube with one or more partial walls mounted in the tube. When held at an angle above the angle of repose for the free flowing material and rotated 180.degree. around the longitudinal axis of the tube and then another 180.degree. in either direction, free flowing material is measured and dispensed. The device can measure and dispense a variable amount of material by changing the volume of a variable volume chamber. The device can also be automated to turn by an electric motor or a mechanical device operated by a hand squeezed trigger. The device can be a hand-held tube for dispensing free flowing materials, or it can mount on the top of a container of free flowing materials, and be used to dispense quantities of the free flowing material on demand.

Abstract: A substantially flat collapsed plastic bag with an evacuation form unit insert positioned therein as manufactured to serve as a form about which the filled bag will collapse as it is emptied. The form unit comprises a ring for mounting the unit on the spout of the bag and a multi-channel form extending radially from the ring and hingedly connected thereto. A simple method is provided for manufacturing the bag with the form unit insert.

Abstract: A two piece dispensing closure for a container with a dispensing orifice in the front section and an elevated rear land that has a pivot recess adapted to receive a separate lid with a recess or groove which enables the lid to be rotated to about 150.degree. from the closed position. The front section of the lid is generally circular with a pivot post at its rear. A chamfered elevated land which saves plastic material and is easier to mold, is also disclosed.

Abstract: A prior art precompression metering pump which incorporates a differential piston forming part of the pump chamber inlet valve and its outlet valve is difficult to prime, especially in the case of metering paste products. In the improved pump there is disposed between the differential piston and the main piston of the pump a collar consisting of a ring from which project substantially axial tongues which are slightly inwardly inclined and each provided with a head. The collar moves inside the pump body so that normal operation proceeds as if it were not present. To prime the pump, however, the user depresses the collar until it contacts a step on the pump body. The tongues then bend so that their heads, interposed between the two pistons, move the latter apart (by a wedging effect or by a lever arm effect, or by a combination of the two). This is followed by mechanical opening of the pump chamber outlet valve whereby the air initially contained in the pump chamber escapes to the exterior.

Abstract: A cup type liquid dispensing machine in which the liquid-supplying system is a closed airtight circuit in the form of bag-in-box packages. The packages are connected to a dispensing pump which supplies the liquid to a dispensed and supported cup. Waste liquids from the machine are collected by various lines which are coupled to a flexible bag. A movable member engages the bag and activates a control switch to stop the machine as the bag becomes full.
