  • Patent number: 5167348
    Abstract: The present invention is a tube squeezer designed to squeeze excess toothpaste, ointments, and similar materials trapped at the bottom of a collapsible tube dispenser. Two cylindrical rods positioned in parallel have notches to guide and hold two bands or O-rings at each end. The bands or O-rings provide pressure against the tube which is sandwiched between the two rods. Sliding the whole assembly up the length of the tube forces the residual contents to the top.

  • Patent number: 5118011
    Abstract: A food roller dispenser for dispensing the contents from a flexible pouch-like food container by passing the container between a pair of elongate rollers having teeth which mesh and overlap each other to drivingly grip the container between the meshed teeth and squeeze the contents from the container during counter-rotation of the rollers. Each of the rollers is of a solid one-piece plastic construction having roller bearing portions adjacent opposite ends which are removably captured in easily disassembled bearing blocks for ease of cleaning. One of the rollers is driven by a handcrank which, through a set of gears mounted on shaft extensions on the ends of the rollers, drives the other roller in the opposite direction.

  • Patent number: 4846370
    Abstract: Systems are described for using multiple closely-packed spheres. In one system for passing fluid, a multiplicity of spheres lie within a container, with all of the spheres having the same outside diameter and with the spheres being closely nested in one another to create multiple interstitial passages of a known size and configuration and smooth walls. The container has an inlet and outlet for passing fluid through the interstitial passages formed between the nested spheres. The small interstitial passages can be used to filter out material, especially biological material such as cells in a fluid, where the cells can be easily destroyed if passed across sharp edges. The outer surface of the spheres can contain a material that absorbs a constitutent in the flowing fluid, such as a particular contamination gas, or can contain a catalyst to chemically react the fluid passing therethrough, the use of multiple small spheres assuring a large area of contact of these surfaces of the spheres with the fluid.

  • Patent number: 4805805
    Abstract: A tube dispenser utilizes a ratchet actuated pusher for squeezing the contents from a tube. In a first embodiment, a tube is supported on a support plate with a nozzle of the tube extending through an aperture formed in an end wall connected to the support plate. A handle, mounted on an opposite end wall, has an attached ratchet actuation lever. A toothed rod extends through an aperture in the end wall adjacent the handle. A pair of frame rods extend betwen the end walls. By squeezing the ratchet actuation lever, the pusher is caused to advance along the support plate, squeezing the tube walls between the pusher and the support plate. Three different configurations of the pusher are disclosed. The pusher may be formed as a cylindrical bar, a right angle channel, or as a plurality of rotatable rollers. In a second embodiment, the tube is supported within a receptacle, with a nozzle of the tube extending through an aperture in an end wall of the receptacle.

  • Patent number: 4627551
    Abstract: Dispenser system includes a pair of squeeze rollers for squeezing putty-like material from a bag-like container as the container is pulled between the rollers during turning of the rollers in opposite directions. Each of the squeeze rollers has a rubber-like cover whereby the rollers may be compressed together to ensure that the rollers will frictionally grip opposite sides of the bag passing therebetween to uniformly pull the bag between the rollers during turning of the rollers to squeeze the material out of the container. The container itself is preferably made from two flat sheets of plastic material which may be joined together by heat sealing. The two sheets are initially laid flat one on top of the other and heat sealed along the side edges and bottom which is formed into a funnel-shaped spout. The top is left open to permit filling of the container with the desired quantity of putty-like material.

  • Patent number: 4508242
    Abstract: The toothpaste dispensing apparatus of my invention comprises an enclosure which houses multiple separate tube holders for holding the tubes of paste. It, also, contains a reversible motor connected by a worm screw to a holder containing a pair of movable rollers for dispensing tooth paste, shaving cream, etc. from any of its multiple positions. The paste is discharged at the bottom of the inner tube holder by a squeezing pressure exerted upon the tube by the pair of rollers which moves downward over the inner tube holder. This device is equipped with a switch for automatically reversing the downward direction of the rollers when the contents of the tube have been exhausted. A most unique feature is the provision for housing several tubes and the selector knob, which allows the operator to choose either one of the several tubes on which to operate without having to dismantle or load or unload the device.

    Abstract: This invention is directed to a dispenser for housing and dispensing on demand a predetermined amount of the semi-fluid contents of a compressible tube container, such as a toothpaste tube. The dispenser for automatically dispensing a semi-fluid material that can be caused to flow slowly from a compressible tube comprises:(a) a structure for holding the tube in a position such that the opening in the tube extends downwardly;(b) an arrangement for slidably closing the end of the opening in the tube;(c) a device for agitating upon manual command the tube and semi-fluid contents such that the contents are induced to flow;(d) the above recited arrangement withdrawing the slidable closure from the opening upon manual command to thereby permit the material to flow gradually out of the tube.

  • Patent number: 4405062
    Abstract: A flexible tube dispensing device designed for use with flexible tubes containing pastes, gels, liquids and certain powders. In use the dispensing device opens to accommodate the end of a flexible tube in which is contained a product in paste or other form which may be dispensed by squeezing the tube. Once the tube is inserted, squeezing of a pair of dispensing jaws of the device squeezes the tube to dispense the product and causes the device to advance along the tube as the product is dispensed. This allows almost complete evacuation of the tube contents and dispensing of relatively uniform amounts of contents each time the device is squeezed.

Each frame carries a corrugated roller which mesh with one another and upon rotation collapse a tube passing therebetween. A lever and roller clutch impart unidirectional rotation to the rollers. Cantilever bearings support the rollers and are of a resilient nature to permit displacement of the roller axes while biasing the rollers toward one another and the intermediate tube wall. Roller configuration includes ridges and grooves terminating in surfaces formed on like radii to provide a progressive wedging action on the tube wall. A handgrip is provided which, along with the lever, provides convenient manual control of the tubular container.
