Definitions

  • This invention has as its object a process to maintain separa­te until the moment of use, within a cartridge, container, tu­be of the like, two different substances that are liquid, paste or solid, in powder or granular form and particularly two-com­ponent resins, to mix them at the moment of use and distribu­te them.
  • the process is characterized by the characterizing part of claim 1, the device is characterized by the characterizing part of claim 2.
  • the device according to the first 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 hardener 7, which must be kept separate until the moment of use and, when it is de­ sired to use them, must be intimately mixed and then distri­ubbed by opening 2 after cap 3 and rod 5 are removed.
  • a resin i.e. resin 6 and hardener 7, which must be kept separate until the moment of use and, when it is de­ sired to use them, must be intimately mixed and then distri­mped by opening 2 after cap 3 and rod 5 are removed.
  • 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.
  • membrane 4 keeps the two substances separate.
  • membrane 4 is perforated by points 8 solid with disk 14.
  • Annular periphery 4 ⁇ of membrane 4 exhibits 0 ring 16 made, for example, 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.
  • - Figure 2 illustrates a variant according to which rod 5 is introduced tight from bottom 18.
  • Said bottom 18 slides 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.
  • 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, 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.
  • Figures 3, 4, 5 represents a variant according to which rod 5 is shapened to a point 5 ⁇ and exhibits an annular groove 25 that restrains piston 21 with annular projections 23 and finned, preferably made of a plastic, provided with openings 22 (fig. 4).
  • the unit of the rod and piston serves either to break membrane 4 or to mix the two substances.
  • Separation of the two different substances and in particular of the two different resin components can also be obtained by introducing at the moment of making (filling) of the cartridge, container, tube or the like, a container that is spherical, cylindrical or in any other shape, having walls that are easy to tear or break (for example, of glass), a container holding one of the two substances or components to be mixed, while the other substance or component placed in the container is out­side said tearable or breakable container.
  • Rod 5 (fig. 3), sharpened to a point at 5 ⁇ , able to be unfa­ stened from piston 21 by groove 25 working with projection 23 of piston 21, is provided to break said container, while joined to piston 21 provided with openings 22 contributes to the mix­ing.
  • the membrane 4 can be a simple piece with annular part 4 ⁇ or the whole can be made in two different parts, joined together.
  • the thickness of membrane 4 and that of annular part 4 ⁇ are made on the basis of the size (diameter) of tube or container 1 and the aggressiveness of substances 6, 7 contained in con­tainer 1.
  • Disk 14 can be made, for example, of metal or synthetic re­sin.
  • the position of membrane 4 with disk 14 can be located at any height along the axis of container 1.
  • the devi­ce comprises a container that is spherical, cylindrical or in any other shape, having easily tearable or breakable walls, containing one of the two substances or components to be mixed, while the other substance or component placed in the container is outside said tearable or breakable container.
  • Means are provided to tear or break said container while a piston or equivalent makes it possible to mix the two components at the moment of use and to distribute them mixed from the output opening of the container.
  • Said means for tearing and breaking said container consist of a threaded rod or rod provided with flexible teeth.
  • the rod is preferably pointed at its front end and provided with a handle, at its back end.
  • the rod is axially introducible in the cartridge container or the like perforating the diaphragm or the cap that closes said container and is guided by a gui­ de piston that can slide in said cartridge, container, tube or the like, breaking said container, if necessary, and scre­wing on the threading or inserting its teeth into complemen­tary recesses of a stirring disk or equivalent that serves for mixing the two components.
  • said container is made of glass or fragile synthetic material and is free or bound, i.e., supported by said guide piston, while the parts of the cartridge, container or the like are of a flexible material so that breaking of the container can also be performed by manual­ly or mechanically compressing said flexible cartridge.
  • the device comprises car­tridge, container, tube or the like 1 preferably of rigid or flexible resins, or aluminum, inside of which is placed contai­ner 26 of glass or fragile synthetic resins, so that its walls can be easily broken either by manually or mechanically compres­sing the walls of cartridge 1, or by running rod 5 through hole or diaphragm 35 of piston 39, and causing container 26 to be passed through by said rod, breaking it.
  • Container 26 contains, for example, one of the components of the two-component resin, while the outside of container 26 is occupied by the other component.
  • Rod 5 provided with handle 11, is preferably pointed and threaded at its front end 5 ⁇ , so that at the end of travel it can be screwed into threading 28 of disk 27.
  • rod 5 there can be, as a substitute for the thre­ading, 3 or 4 fine, flexible circular teeth which are deformed when rod 5 is thrust into or removed from threading 28 of disk 27 or complementary recesses.
  • the teeth are supposed only to resist the agitation force (the resistance is less than that of machine grease) and should be deformed by a jerk of the hand.
  • This disk can act as a piston to mix the two components, espe­cially when they are not fluid, i.e., are gelatinous or pasty.
  • the agitation can occur simply by shaking cartridge 1, and disk 27 can also be absent.
  • the disk is provided with reinforcing fins 27 ⁇ and 27 ⁇ (fig. 6 and 8) and holding lips 27′′′ as shown in fig. 7, or simply pro­vided with numerous holes, or screened.
  • Rod 5 can be provided at end 5 ⁇ with deformable blades or capillaries either to facilitate introduction and extraction of piston 39 through the hole or to obtain a forced agitation.
  • container 26 is provided with an externally threaded neck 26 ⁇ which is screwed into the com­plementary threading of the coaxial hole of piston 39.
  • piston 39 acts as a support for container 26, and cap 33, perforable by rod 5, closes the opening of container 26.
  • Figure 10 shows a further variant, similar to the preceding one, but with cap 33 in a different shape, which can be seen better in figure 11.
  • piston 39 is provided, for perfect sealing, with a flexible widening 39 ⁇ and a V gasket 30, 30 ⁇ replacing a normal O ring.
