Definitions

  • This invention relates to a novel device, being a dispenser for dispensing an extrudable fluid material from a collapsible tube.
  • Many fluid materials are provided in collapsible tubes from which they can be dispensed by extrusion through a nozzle by collapsing the tube, for example under pressure applied by the hand of the user.
  • Such materials include toothpastes, food products, adhesives and cosmetics.
  • Devices which can contain such a tube within a casing and which can transmit dispensing pressure to the contained tube.
  • Such devices are generally intended for example to enhance the aesthetic appearance of the tube, to facilitate storage of the tube, to control the dispensing pressure applied to the tube so that predetermined volumes of the material may be extruded at a time, and to ensure that compression of the tube begins at the closed end and proceeds towards the dispensing end etc.
  • Such devices comprise arrangements of tube compressing means such as jaws, rollers etc. which advance from the closed end of the tube toward the nozzle end of the tube and provide a progressive tube compressing action as they advance.
  • the present invention provides a dispenser having a construction and method of operation that inter alia allows simplicity of construction and ease of operation.
  • the invention provides a dispenser for dispensing an extrudable fluid material from a collapsible tube having a closed end and an dispensing end, comprising: a tubular casing having a longitudinal direction and a lateral width direction, and having a dispensing end, the casing being adapted to retain the collapsible tube; a piston, located within said casing and having therein, or together with part of the casing defining, a slot oriented in the width direction of the piston, the slot being capable of receiving the closed end of the tube when the tube is within the casing, the dimensions of the slot being large enough to allow passage of an at least partly collapsed tube therethrough, but small enough that there is contact and friction between the wall of the at least partly collapsed tube and the sides of the slot; the piston and the casing having co-operating non-return means thereon which when in co-operation permit longitudinal movement of the piston effectively only towards the dispensing end of the tube; the dispenser being further provided with tube urging me-ans to urge the collap
  • the extrudable fluid material may be a pasty fluid material and may for example be a toothpaste, a food product, an adhesive or a cosmetic.
  • the collapsible tube may be a conventional collapsible tube of the type well known in the art in which such materials are commonly supplied. Such tubes are of a generally circular or oval cross section when filled and prior to collapse. They have a nozzle through which the material may be extruded and a closure at their dispensing end, and have a closed end in which the extreme end of the tube is collapsed flat and sealed to form a flat "fishtail" type seal.
  • the dispenser of this invention is particularly suited to use with such tubes.
  • the casing may be in the form of a casing with a removeable end closure. Such an end closure may suitably be at the dispensing end.
  • the cross sectional shape and size of the piston over at least pan and preferably over substantially the whole of its length and perimeter conforms generally, suitably closely, to the cross sectional shape and size of the casing, so that the piston may slide smoothly and easily within the casing.
  • the slot in the piston preferably occupies substantially the entire width of the piston between its side walls.
  • the slot preferably conforms closely to the dimensions of the collapsed tube.
  • the slot is suitably substantially elongated rectangular or elongated lozenge in shape.

  • the slot may be formed as the gap between a roller in the piston with its axle oriented parallel to the width direction of the casing, and a passage forming wall in the piston. If such rollers are used it may be necessary to provide them/it with one-way rolling means so that the roller(s) can only rotate such that the part of their/its perimeter which forms the slot can only move away from the dispensing end.
  • Such one-way rolling means are known in the art, eg toothed sprocket wheels etc.
