Abstract

The device, according to a preferred embodiment, comprises a container (1) with rigid or flexible walls containing one or two resin components and a container (26) of thin glass or fragile synthetic resin containing the other component. Container (26) at the moment of use is broken either by manually compressing container (1) or inserting a rod (5) provided with handle (11) through guide piston (39) and through said container (26) until reaching disk (27) to which the rod is screwed or fastened by flexible teeth, a disk that serves as a mixing piston to mix the two components, distributing them through output (2).

Description

  • This invention has as its object a device to maintain separate until the moment of use, two different substances and particularly two-component resins, to mix them at the moment of use and to expel them through output, comprising a cartridge, tube, or the like, a membrane located inside said cartridge, tube of the like, so as to divide it into two separate chambers, to maintain the two substances separate until the moment of use, a piston provided with means for perforating said membrane and holes to allow the passage of the two substances during the mixing thereof.
  • The DE-A 2 948 748 publication relates to a cartridge to maintain separate until the moment of use the two components of a resin, with a membrane, i.e. of a thin aluminium metal sheet, located inside said cartridge so as to divide it into two separate chambers, to maintain the two substances separate until the moment of use, a piston to break said membrane and to mix the two components expelling them through output.
  • The FR-A 2 129 178 patent relates to a device having the shape of a syringe in which two different substances, particularly a cosmetic active product and an excipient, are maintained separate through a membrane until the moment of use and then mixed, the piston being provided with a perforator of said membrane.
  • The device according to the present invention differs from those of said two prior art citations being characterized in that the membrane is provided with an annular periphery tight with respect of the walls of the cartridge, tube or the like and with means to fasten said annular periphery to the piston after the perforation of the membrane, in order to act as a complementary piston during the mixing of the two substances.
  • According to a preferred embodiment, said annular periphery of the membrane exhibits on the outside at least an O ring, tight with respect to the walls of the cartridge, tube or the lilke and on the inside an annular projection which is inserted in a complementary groove of piston.
  • The advantages of the device according to the present invention with respect to those of the two prior art citations are the following:
    • a) the fact that in the device according to the present invention, the membrane, after perforation, being fastened to the piston, allows the perfect mixing of the two substances since the membrane does not hinder the movement of the piston;
    • b) the presence of the annular 0 ring, at the periphery of the membrane, allows the perfect sliding of the piston;
    • c) all the mixed resin can be expelled from the container.
  • The accompanying drawing represents:
    • - in fig. 1 the axial section of a preferred embodiment of the device in question, in a non-limiting, non- binding way;
    • - in fig. 2 a variant of said embodiment.
  • The device according to said embodiment, applied to any cartridge, tube or container 1 (fig. 1), with an output opening 2 that can be closed by cap 3, makes it possible to create two separate chambers 6, 7 in each of which is contained a substance different from the other, for example, two components of a resin, i.e. resin 6 and harderer 7, which must be kept separate until the moment of use and, when it is desired to use them, must be intimately mixed and then distributed by opening 2 after cap 3 and rod 5 are removed.
  • To obtain this, the device comprises membrane 4 which is easy to perforate, made, for example, of synthetic resin or sheet metal, exhibiting annular periphery 4' reinforced, i.e. thickened to allow sliding along the inside walls of container 1.
  • During storage of all the material, membrane 4 keeps the two substances separate.
  • At the moment of use, by acting on handle 11 of rod 5 in the direction of arrow 12 and optionally also by causing rotation in the direction of arrow 17, membrane 4 is perforated by points 8 solid with disk 14.
  • By repeatedly moving the unit made up of perforated membrane 4 and disk 14 in both directions, axially along container 1, the two liquids 6, 7 are drawn from one chamber 6, 7 to the other until the mixing is complete, after which, with cap 3 and rod 5 removed, the mixture is made to come out of opening 2, optionally screwing a flexible distribution tube on the threads of the cap.
  • Annular periphery 4' of membrane 4 exhibits O ring 16 made, for exaple, of teflon (polytetrafluoroethylene), neoprene, etc. while ribbing 4" inside ring 4', ribbing which is inserted in complementary annular groove 15 of disk 14, assures the dragging of the entire unit.
  • Disk 14 exhibits holes 13 that work with holes 10 made in membrane 4 by points 8 to allow the passage of the two liquids contained in chamber 6, 7 from one chamber to the other.
  • The bottom 18 can slide also in a tight manner along the inside walls of cartridge, tube or container 1, driven by an ejection piston (not shown) or with compressed air in the direction of arrow 19, after rod 5 is removed.
  • Figure 2 illustrates a variant according to which rod 5 is introduced tight from bottom 18.
  • Perforation points 8 can be replaced by any other means suitable for perforating membrane 4 according to small disks that disappear in the mixture of the two substances 6 and 7. Rotation of rod 5 makes it possible also to cut the rings of the membrane by points 8.
  • Rod 5 can have a polygonal section and exhibit a side pin to be able to insert it like a bayonet into disk 14 and pull it out when it is necessary to distribute the mixture from opening 2.
