Definitions

  • the technical field of this invention relates to devices for the dispensing of non-solid, viscous materials BACKGROUND ART
  • Cartridges for storing and dispensing viscous materials such as resins, sealing compositions, dental compositions, or insulation compositions are known in the art
  • Such cartridges generally comprise an outer casing containing at one end, an end piece which attaches to an application nozzle and at the other end, a rear thrust wall designed to slide toward the end piece and force the viscous material out of the nozzle This sliding of the rear thrust wall is brought about by a piston which is generally an integral part of a manual operating device, usually in the form of a gun equipped with a rack or friction advance mechanism
  • Some viscous products consist of several viscous components which must be mixed, in given proportions, only at the time of application It is known in the art to store the viscous components in multiple containers inside cartridges in such a way that the advancing rear ⁇ thrust wall will force the components through a single mixing nozzle whereby the components become mixed at the time of application
  • U S Patent No 5,339,992 to Barthomeuf et al discloses a cartridge comprising an outer casing and an inner casing Each casing holds a viscous component of a final product
  • the cartridge has a front end piece for receiving an application nozzle and a rear thrust wall which drives the components forward and through the nozzle when it is advanced
  • the cartridge and containers are designed for a single use, and are constructed of recyclable materials
  • the chambers may have a variety of ratios of the several components
  • the cartridge contains a tubular casing, a forward end cap having an orifice capable of snugly holding a piece capable of coupling with a conventional mixing nozzle, and a rear thrust wall capable of being urged forward by the piston of a conventional caulking gun
  • the container is made up of multiple collapsible chambers containing closed rear ends, closed side edges, at least one edge being in common for at least a portion of the length of a side, and a forward end in which the forward edges of the chambers are sealed to a forward end piece
  • the collapsible chambers may be sealed bags made of sturdy plastic or expandable and compressible chambers having accordion configurations
  • Each forward end piece has a body portion, a shoulder portion, and a neck portion When in position in the cartridge, the multiple body portions of the end piece will form a circle which will abut with the cartridge, the shoulder portions will abut with the end cap, and the neck portion will snugly fit through an orifice in the end cap to engage a mixing nozzle BRIEF DESCRIPTION OF DRAWINGS
