Definitions

  • This invention relates to a container for extrudable material comprising a flexible bag, often referred to as a "chub" containing the extrudable material.
  • Chubs are conventionally manufactured from flexible sheet synthetic plastics material formed, during the manufacturing process, into a continuous tube defining a longitudinal cavity filled with the extrudable material. For some applications a tuck is formed in the tube so as to define a second longitudinal cavity extending alongside the first, this second cavity being filled with a second extrudable material. On dispensation from the chub, these materials react, normally to produce a hardening effect, though in principle other chemical effects such as foaming would be possible. After filling, pairs of wire pieces are crimped around the tube at regular intervals and the tube is then cut between the crimps of each pair to form individual chubs each sealed at opposite ends.
  • each chub is then placed in a cylindrical injection moulded cartridge so that one crimped end of the chub passes through an outlet port of the cartridge.
  • a plunger or piston slides into the other end of the cartridge.
  • the user cuts through the chub, just inwardly of the crimp, to allow its contents to be released.
  • the user screws a nozzle or mixer onto the cartridge and uses a conventional extrusion gun to drive the plunger further into the cylinder, compressing the chub and forcing its contents out of the outlet port and nozzle.
  • a twin compartment chub is employed as described above, it is normal for the nozzle to contain an insert or mixer element designed to assist in the mixing of the components.
  • Patent specification EP0754633 which forms the basis for the preambles of appended claims 1 and 4, recognises the above problem and attempts mitigate it in the arrangement shown in Fig 3 by providing a cutting mechanism that is operated immediately before use of each cartridge. However this does not solve the problem that the user has to perform a cutting operation
  • Patent specification WO2007/026169 describes a proposal to overcome the problem by using a wire crimp at one end of the chub that is sufficiently weak to be forced off the chub by the pressure created by the extrusion gun.
  • this necessitates the use of a non-standard chub manufacturing process.
  • the requirement to weaken the chub sufficiently to allow it to break open under the pressure applied by the extrusion gun necessarily compromises the chub's effectiveness in safely containing its contents before use.
  • a method of preparing a container of extrudable material starting from means defining an outlet for the material, closure means for the outlet and a flexible bag that contains the extrudable material and has a discharge end closed by a crimp; the method comprising the steps of
  • container for extrudable material comprising: a. means defining an outlet for the material;
  • a removable release member screws on to the outlet and is used to hold the plug firmly in position until ready for use.
  • the release member and the plug are formed with detent means designed so that, when the release member is screwed into position during manufacture, the release member and the plug or other closure means become locked together in an axial direction (whilst still allowing relative rotation about the axis). Consequently, when the release member is removed by the user, the closure means is automatically removed with it. The user then needs only to fit the nozzle onto the outlet and to place the cartridge in a suitable gun before use.
  • the "detent means" can easily be formed by a resiliently flexible flange on the release member designed to snap over a corresponding shoulder on the outlet port (or vice-versa).
  • the illustrated cartridge (shown with its middle section removed for ease of illustration) comprises a cylinder 1 of cardboard or other biodegradable material having an axis Y - Y and a plunger 1A inserted at one end.
  • the other end of the cylinder 1 receives an end piece 2 formed from injection moulded synthetic plastics material.
  • the end piece 2 defines an outlet 3 having a screw threaded exterior surface 4 and a cylindrical inner surface 5.
  • a twin-compartment chub 6 is formed from flexible laminated sheet plastics material having at least one layer specifically designed to isolate its toxic contents from the atmosphere. It is formed continuously as a tubular structure having a tuck or pleat so as to define two compartments each extending along the whole length of the chub structure.
  • a chub 6 is inserted through the left hand end of the cylinder 1. Neither compartment of the chub is filled to maximum capacity, allowing one crimped end to be squashed and manipulated so that the crimped end projects through the opening 3. The projecting end carrying the crimp 9B is then folded over the edge of the outlet 3 and a plug 10 inserted into the latter.
  • the plug 10 has a lip 10A and a cylindrical body portion rounded at its free end to facilitate insertion into the outlet 3.
  • This body portion has a flat (in alternative constructions this could be a groove) precisely dimensioned so that, when the plug is pushed home, the resulting space between the plug and the outlet surface 5 is filled by the flexible plastics material of the chub.
  • the lip 10A has a groove to receive the folded-over end of the chub.
  • a release member in the form of a cap 11 is then screwed on to the outlet 3.
  • a cam surface 11B of a resiliently flexible internal flange 11A of the cap engages against a corresponding cam surface 10B of the plug, causing the flange 11A to bend and then spring with a snap action into a groove 10C of the plug.
  • the flange 11A and groove 10C thus form a detent, latch or locking mechanism, having the effect that, when the cap is removed by the user, the plug 10 is removed with it.
  • the cardboard tube 1 can be made of sustainable and recyclable material and is less costly to supply than the conventional tubular injection moulded cartridge.
  • the cardboard cylinder 1 is not required since the cylindrical cartridge holder will provide its function of resisting radial distention of the chub during the extrusion process.
  • FIG 4 there is shown an alternative embodiment of the invention.
  • This embodiment includes components exactly the same as those shown in Figs 1 to 3 with the exception that the cardboard tube 1 and the plunger 1A are omitted.
  • the remaining components are placed in a conventional extrusion gun of the type that includes a permanent, i.e. non-disposable, cylinder 14 which, for the purposes of illustration is shown as transparent, though in practice this will not always be so.
  • a plunger 15 forming a conventional part of the extrusion gun and attached to shaft 16, is driven, by the action of trigger 17, directly into engagement with the chub.
  • the empty chub and its associated components 2 and 12 are discarded for recycling.
  • the plug 10 is replaced by a plug 18 formed as a single moulding having two parts 18A and 18B joined by a hinge 18C.
  • the two parts are designed to hinge closed with a small space 18D between them, dimensioned to receive exactly the end of the chub but none of its contents so that a perfect seal is formed when the two parts of the plug are held together by the interaction of the plug with the interior surface of the outlet.
  • the end of the chub and the crimp are removed during manufacture, using a knife K.
  • Fig 7 shows another variation where, the closure means is defined by a ring 19 that surrounds the outlet so that the end of the chub is trapped by radial pressure between the outlet and the ring.
  • the excess material at the end of the chub and the crimp are removed by knife K during manufacture and before the release member in the form of cap 11 is applied.
  • the cap 11 is shown as closed but this is not essential and it could equally well take the form of a ring open at both ends.
