Abstract: A device for squeezing various household collapsible tubes comprises two lever handles, two pintles, two torsional springs, a primary roller, and a secondary roller. The lever handles are held together by and are free to rotate about the two pintles, forming a double non-crossing class 1 lever arrangement. The rollers, held in gudgeons by snap fit, are also free to rotate. The primary roller is distinguished from the secondary roller by having a crank at one end. The torsional springs, anchored by the pintles, provide a torque which causes the two rollers to clamp together. Operation of the tube squeezing device proceeds by inserting the crimped end of a collapsible tube between the rollers and turning the crank, thereby turning the rollers so as to squeeze the tube flat and to push its contents toward the nozzle end. Insertion and extraction of the tube is effected most readily by applying a compressive force to the two lever handles, creating a gap between the rollers for the tube to easily pass through.

Abstract: An extractor neatly and cleanly empties a tube of toothpaste, or the like. The extractor includes a pair of roller assemblies and a pair of end caps. Each roller assembly has a pair of balls which fit within sockets formed in the end caps. In one embodiment, the balls have slits to enable sections of the balls to move towards and away from each other. The balls are made of resilient material, such that the sections tend to assume a spaced-apart position in the absence of an applied compressive force. As the ball is urged into the socket, the sections of the ball become compressed, thus enabling the ball to pass through a hole in the end cap and into the socket. When the ball has reached its socket, the sections return to their initial position, so as to lock the ball within the socket. In an alternative embodiment, the ball is not compressible, but is instead inserted into a deformable socket having resiliently movable walls which lock around the ball.

Abstract: A mixing and dispensing system for reactively combining organic chemical components to produce a rapidly polymerizing material for use in molding and encapsulating small and usually delicate devices, such as electronic components. The system uses a novel mix head incorporating a high speed rotary mixer having magnetic coupling for mixing and injecting relatively low viscosity polymerizing materials into a mold. The chemical feed to the mix head is from special chemical handling equipment. The design of the system eliminates the need for material control valves and enables relatively low feed line pressures. A novel chemical handling subsystem uses special tubular containers provided by the chemical material manufacturers that mount on specially designed dispensing equipment, and do not require special storage, handling, or mixing by trained personnel.

Abstract: An automatic toothpaste dispenser is disclosed which forces a discreet amount of toothpaste from a tube by moving a plunger in a downward direction. The toothpaste dispenser has two halves which are hinged at the top to allow the tube of toothpaste to be inserted in the device. The front of the device has a plunger which activates two rear rollers inside the device which move downwardly to squeeze toothpaste out of the tube. The front plunger is attached to a front inner mechanism having engaging teeth. The inner mechanism slides on pins which are inserted into grooves. The grooves allow the inner drive mechanism to move down until the lower pins of the drive mechanism engage a guide which pushes the drive mechanism forward to engage corresponding teeth on the rear housing containing the rollers. A spring always brings the front inner drive mechanism back towards the top of the case.
