Definitions

  • the invention relates to a multi-component cartridge having the features of the preamble of claim 1.
  • the tube contains at least one container, so that the components are separated by the container wall.
  • the container may be a tubular bag, a blow molding or the like.
  • the other component is either also stored in a container, so for example in another blow molding, another tubular bag or a separate compartment of the tubular bag, or it fills the remaining space of the tube, that is essentially from the container of the first component and the inner wall limited to the tube.
  • two or correspondingly more containers would be arranged in this case, while a component would be filled container-free in the tube.
  • the illustration should always be based on two-component masses.
  • the advantage of the systems with a tube and a container is on the one hand the expressibility with conventional extrusion guns and on the other hand a favorable production compared to systems with containers for each component.
  • it can easily lead to a tilting of the container within the tube, because due to the compressive forces to compress the container and the typically different viscosities of the components transverse forces occur.
  • the tilting leads to an uneven discharge of the two components, which means that the mixing ratio of the components on the Auspressvorgang varies. This is undesirable because of the subsequent chemical or physical processes.
  • the object of the invention is therefore to provide a multi-component cartridge with a simpler, cheaper producible structure, which ensures a uniform discharge of the components with a constant mixing ratio.
  • the invention proposes a multicomponent cartridge for two or more components of a flowable mass.
  • flowable compositions are meant those substances which, due to their viscosity and, if appropriate, granulation, allow a manual or mechanical squeezing out of the cartridge.
  • the multi-component cartridge has a tube for receiving the mass, which in particular can be cylindrical, wherein in principle other shapes are possible.
  • the multicomponent cartridge has an outlet opening for the mass, wherein this outlet opening has, in particular, a reduced cross-section with respect to the tube cross-section and can be closed.
  • the outlet opening may be designed for mounting a static mixer.
  • the components of the mass are stored separately from each other in the tube, wherein at least for a first component, in particular a longitudinally compressible container is provided.
  • a first component in particular a longitudinally compressible container is provided.
  • longitudinal or axial refers to the longitudinal direction of the multi-component cartridge and thus to the Auspressraum.
  • the container is supported distributed over the circumference such that tilting of the container within the tube during extrusion is prevented.
  • the support is made via a concern on the inside of the tube, in particular pressure can be transmitted via the contact points.
  • the support thus takes place in that opposite points of the contact points on the inside of the tube ensure that there is no tilting or buckling of the container.
  • the multi-component cartridge thereby provides a constant Mixing ratio when pressing the mass. At the same time no gluing, welding or the like.
  • a fixation can be provided, for example, to prevent a rotation about the longitudinal axis of the tube.
  • the container according to the invention should not fill the entire cross-sectional area of the tube, but it should be arranged over the entire length of the container a container-free cross-sectional area for flow of a second component substantially.
  • This makes it possible that a second component of the mass container-free, that is, between the container and the inner wall of the tube, stored and can be pressed out safely.
  • the multicomponent cartridge for example, include a third or fourth component, so additional containers can be provided in addition.
  • the containers can also support each other, that is, the support distributed over the circumference on the inside of the tube takes place for the entirety of the container.
  • a single container can also be replaced by two or more individual containers that supplement each other to the same geometry, if the number of components requires this.
  • the abutments do not have to extend over the entire length of the pipe. At cross-sections with contact points, however, these are preferably distributed symmetrically over the circumference. This results in a particularly uniform and thus stable support.
  • the multi-component cartridge has a head piece on the tube, which can in particular also form the outlet opening.
  • the head piece can serve as a contact surface for the container for receiving the axial compression forces. There is thus the risk that the container seals at this point at the same time and the second component can not flow in the direction of the outlet opening.
  • the invention therefore proposes that one or more elevations for axial support of the container are formed on the inside of the head piece in the direction of the container. Grooves or the like arise between the elevations as flow channels.
  • the container is designed as a blow-molded part.
  • other production methods are also conceivable, for example the production as an injection-molded part.
  • the container has, in a preferred embodiment, an outlet which is arranged centrally with respect to the outlet opening.
  • the second component flows around the first component during pressing, as a result of which the components can be easily mixed further.
  • the closure and effective sealing is facilitated by a central arrangement. It is not necessary for the outlet opening itself to be centered with respect to the cross-section of the tube, but such symmetrical construction results in simplifications in the production of the multi-component cartridge.
  • the multi-component cartridge 1 is used to store a two-component, flowable mass, for example an epoxy resin, wherein the two components can be stored separately and pressed together with a fixed mixing ratio.
  • the mass itself is not shown for clarity.
  • the multi-component cartridge has as in FIG. 1 represented as a basic body, a cylindrical tube 2, which is located at one end reduced in one piece to a head piece 3 in diameter. Due to the diameter reduction arises inside a stop shoulder 4, to which a tubular, cylindrical neck 5 with an external thread 6 connects. The external thread 6 serves to screw on a lid or a static mixer (not shown). At its opposite end, the tube 2 has no change in diameter. It is closed by an inserted piston 7.
  • the piston 7 is shown simplified as a cylindrical block. In fact, it has a more detailed geometry with a sealing lip, stiffening ribs, vent hole and the like on what it does not matter in this context.
  • a container 8 in the form of a blow molding.
  • the container 8 is additionally in FIG. 2 shown in perspective.
  • the container 8 serves to store a first component of a mass. He has the basic shape of a cylindrical bellows, that is, he has circumferential predetermined bending points 9, 10 in the form of pleat-like diameter expansions or - constrictions.
  • the predetermined bending points 9, 10 can thus be differentiated into convex outer predetermined bending points 9 and concave inner predetermined bending points 10.
  • At one end of the container 8 is located on the piston 7.
  • the container 8 is closed at this end by a rear wall 11. At the opposite end of the container 8 abuts against the stop shoulder 4 of the head piece 3.
  • the container 8 is also reduced at this end so far in diameter that it extends to a tubular, open outlet 12 centrally through the nozzle 5 and this even extends slightly beyond the longitudinal direction of the multi-component cartridge 1.
  • its outer diameter is slightly smaller than the inner diameter of the nozzle 5, so that an annular outlet channel 13 remains.
  • Outlet 12 and outlet channel 13 together form the outlet opening 14 of the multicomponent cartridge 1 for the mass.
  • the second component of the mass is arranged in the remaining space of the tube 2 minus the container 8.
  • the container 8 has at its outer predetermined bending points 9 an outer diameter which corresponds approximately to the inner diameter of the tube 8 in this area.
  • the outer predetermined bending points 9 are distributed over the circumference four points flattened, that is, the predetermined bending points 9 do not have the shape of a circle in this area, but form secant-like flattenings 16. Accordingly the multicomponent cartridge 1 in this area a container-free cross-sectional area A, as in particular in FIG. 3 shown.
  • the term "container-free” refers not only to the wall of the container 8, but also to the volume enclosed by the container 8.
  • FIG. 4 shows an alternative cross section FIG. 3 ,
  • the container 8 ' is not rotationally symmetrical, but it is, starting again from the basic shape of a cylindrical bellows, only on one side of the outer predetermined bending points 9' a flattening 16 '.
  • the contact points 20 ' are not distributed symmetrically over the circumference.
  • This geometry has the advantage that the second component can be filled more easily due to the space available.
