Abstract

The device comprising means (5) for tearing or breaking a container (26), consists of a rod (5), threaded or provided with flexible teeth (5′), and preferably pointed at its front end and provided with a handle (11) at its back end. The rod can be axially introducted into the cartridge tube or the like (1) by perforating cap (33) which closes said container. The rod (5) is guided by a guide piston (39) and can slide in said cartridge, tube or the like (1), breaking said container (26), if necessary, and screwing (fig. 1) on threading (28) or inserting its teeth (5′) in complementary recesses of an agitation disk or equivalent (27) that serves to mix the two components.
Said container (26) is preferably being 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 said running rod (5).

Description

  • This invention has as its object a device to maintain separate until the moment of use, within a cartridge, tube or 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 device is characterized by the characterizing part of claim 1.
  • The accompanying drawings represent:
    • - in figure 1 the axial section of a preferred embodiment of the device in question, in a non-limiting, non-binding way;
    • - in figures 2 to 8 some variants of said embodiment.
  • The French Patent no. 2 129 178 discloses, for the same purpose, a device having the shape of a syringe in which is introduced a cylindrical container for one of the two components to be mixed at the moment of use, the body of the syringe containing the other component.
  • The plunger breaks initially only the fore base of the container, mixes the two components, then breaks the hinder base of said container and expels the mixture from the output opening of the syringe. The need to break the fore and the hinder bases of the container in two different steps requires complicated means to control the stroke of the plunger.
  • All of these complications are avoided with the device according to the present invention.
  • With reference to figures 1, 2, 3, the device comprises cartridge, tube or the like 1 preferably of rigid or flexible resins, or aluminium, 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 compression of 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.
  • When container 26 is broken at the moment of use, the two resin components are mixed and distributed by opening 2.
  • 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.
  • At the end of 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.
  • When they are fluid, 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˝ (figures 1 and 3) and holding lips 27‴ as shown in figure 2, or simply provided with numerous holes, or screened. Underlying piston 39 to which perforable cap 33 is screwed, in this case acts as a guide for rod 5.
  • 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.
  • In the variant shown in figure 4, container 26 is provided with an externally threaded neck 26′ which is screwed into the complementary threading of the coaxial hole of piston 39.
  • In this case, piston 39 acts as a support for container 26, and cap 33, perforable by rod 5, closes the opening of container 26.
  • Figure 5 shows a further variant, similar to the preceding one, but with cap 33 in a different shape, which can be seen better in figure 6.
  • In this case, piston 39 is provided, for perfect sealing, with a flexible widening 39′ and a V gasket 30, 30′ replacing a normal O ring.
  • In figures 7 and 8 is provided a perforable diaphragm 35 which closes the opening of the neck of container 26 when cap 33 is put in place.
  • Other variants are possible, in a manner compatible with what has been claimed, without going outside the scope of protection of the invention.
