Abstract: A system for unloading powdered or granular materials from a container made of flexible material, the system including a line supplying compressed gas to the interior of the container to fluidize the material in the container, and a delivery conduit which may be attached to the container for delivering fluidized material from the container. A pair of arms are movable between a first position in which they are spaced from the container and a second position in which they engage and squeeze the container. Vibrators are provided for vibrating the container. The action of the arms and the vibrators facilitates unloading by breaking up clumps of the material in the container and preventing the formation of air pockets and material bridging.

Abstract: A toothpaste dispenser having a top with a centrally disposed elongated opening; a pair of sides secured to the top, a rear wall secured to the sides, and a first end wall secured to the top and to the sides and to the rear wall. The first end wall has an opening wherethrough a neck of a toothpaste container may pass. The toothpaste dispenser also has a second end wall removably engaged to the top, the sides, and to the rear wall for removing the second end wall to dispose a toothpaste container into the toothpaste dispenser. A lug member is provided for slidably passing through the elongated opening. The lug member interconnects a toothpaste engaging platform member and a hand engaging platform member. A pair of ring toothbrush engaging members is secured to the sides of the toothpaste dispenser for releasably supporting a toothbrush. A fastener is connected to the rear wall of the toothpaste dispenser for securing the toothpaste dispenser to an upright surface, such as a wall in a bathroom.

Abstract: A tool for squeezing out a high-viscosity liquid from a flexible plastic tube container includes a spool having a slot in which the bottom of the tube container is received and locked, and a container holder having a pair of opposed bearing portions frictionally and rotatably supporting thereon a body of the spool, and a pair of opposed engagement portions engageable with a body of the tube container as the tube container is wound on the spool body from the bottom thereof. When a rotational force or torque on the spool is released, the spool is urged to rotate in the reverse direction by a resilient force stored in a portion of the flexible plastic tube container wound on the spool body. However, partly due to a friction acting between the spool body and the bearing portions, and partly due to the engagement between one of the engagement portions and the tube container, the spool is held immovable relative to the container holder against the resilient force of the tube container.

Abstract: A collapsible tube dispenser is disclosed for use with collapsible tubes that contain highly viscous materials, such as silicone gasket RTV. The dispenser provides two engaging plates for squeezing the sides of a collapsible tube, which causes the contents of the tube to be expressed from its open end. The dispenser also includes two handles which can be gripped by a single hand of a human user.

Abstract: An apparatus and a method for dispensing hot melt adhesive or other materials. The apparatus includes a container and an outlet. The container has a first material (the material to be dispensed) disposed therein, which changes from a solid state or a state of high viscosity to a state of low viscosity when heated above a predetermined temperature. The container also has a second material disposed therein, which is adapted to be heated above a predetermined temperature when subjected to microwaves for at least a predetermined period of time. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material. The first material then changes to a state of low viscosity and can be dispensed from the container through the outlet.

Abstract: A toothpaste dispenser includes a base plate and a shorter cover plate connected at their back ends by a hinge. The front end of the base plate is supported by a stand which also forms a cradle for the upper end of a tube of toothpaste. Pressure on the cover plate dispenses toothpaste from a portion of the tube until that portion is substantially flat. The flattened portion is then doubled over and the tube repositioned in the dispenser. The flattened portion is thereby sealed against reentry of toothpaste, and pressure on the cover plate now dispenses from the next higher portion of the tube.
