Definitions

  • the invention relates to a cassette for multicomponent masses having a first receiving body, which has a receiving space for at least one component of the multicomponent mass, and having at least one further receiving body arranged parallel to the first receiving body, the receiving space for at least one further component of the multicomponent mass wherein the receiving space of the first receiving body is larger than the receiving space of the at least one further receiving body.
  • the components of a multicomponent mass such.
  • a multi-component mortar, sealant, foam or adhesive are stored separately from each other until the application of the mass.
  • the components are usually applied via a mixing element, in which the components are mixed to the ready-to-use mass.
  • the components of the multicomponent mass are provided to the user in the appropriate relationship to each other.
  • the ratio between the two components can vary from 1: 1 to 10: 1. Since the receiving body of the cassette are preferably all the same, the ratio of the components of the multicomponent mass is ensured by appropriate ratios of the cross sections of the receiving spaces of the receiving body to each other. Essential for the quality and thus for the safety of use of multicomponent mass is their mixing in the correct ratio of the components to each other.
  • cartridges For storage and for insertion into a receptacle of a press-out device of the multicomponent mass, cartridges are known which have a cassette in whose receiving chambers the components of the multicomponent mass are arranged in the corresponding relationship to one another.
  • the arrangement of the receiving body of a generic cassette to each other is also referred to as a "side-by-side" - arrangement.
  • a generic cassette can be made available to the user as a single part or be part of a Auspress réelles.
  • the components are inserted or inserted into the receiving spaces of the cassette for dispensing the multicomponent mass.
  • the film package comprises two film bags for each one component of the multicomponent mass, which are fixed to a head part with a discharge opening and are each surrounded by a hollow cylindrical receiving body of the cassette.
  • the component in the first receiving body tends to run after it. This means that the required mixing ratio of the component is not guaranteed and thus the desired chemical reaction no longer takes place in the required or in a significantly disturbed stoichiometry.
  • a disadvantage of the known solution is that the components can be dispensed only with a specially trained on this embodiment of the cassette ejection device or trained extrusion.
  • the object of the invention is to provide a cassette for multicomponent masses, which allows over the entire Auspressvorgang a uniform mixing ratio of the components and with conventional Auspresstechnikn with z. B. is two piston rods ausbringbar.
  • the first receiving body is designed with respect to the at least one further receiving body such that it has a lower elasticity than the at least one further receiving body at least in a direction transverse to its longitudinal extension.
  • the first receiving body is stiffer or has a higher rigidity than the at least one further receiving body, with the result that, compared with the at least one further receiving body, it is less transverse in one direction, ie. H. radially or vertically, to its longitudinal extent, which corresponds to the direction of pressurization by the Auspressstoff the squeezing unit can expand.
  • the follow-up volume is throttled from the first receiving body, whereby the mixing ratio in the wake of the components no longer shifts or only after a long time in the direction of only one component.
  • the first receiving body is formed such that the tracking behavior of the ejected from the first receiving body component corresponds to the discharged from the at least one other receiving body component.
  • At least one, extending in the longitudinal extent of the receiving body material weakening is provided on the wall of the at least one further receiving body.
  • the material weakening ensures that the first receiving body has a lower elasticity than the at least one further receiving body, since the at least one further receiving body deforms under pressure more easily in the radial direction to the longitudinal axis of the at least one further receiving body.
  • the material weakening preferably comprises a plurality of axial grooves arranged on the inner wall of the at least one further receiving body and open to the receiving space of the at least one further receiving body.
  • the axial grooves can be easily formed in the at least one further receiving body and ensure advantageous deformability in the radial direction of the at least one other receiving body under pressure.
  • the plurality of axial grooves are provided uniformly distributed along the inner circumference of the receiving space of the at least one further receiving body, which ensures a particularly advantageous deformability in the radial direction of the at least one other receiving body under pressure.
  • the wall thickness of the first receiving body is greater than the wall thickness of the at least one further receiving body, with which the first receiving body has a lower elasticity than the at least one further receiving body and the cassette is easy to produce.
  • the first receiving body and the at least one further receiving body made of different materials.
  • the materials are selected from one or more groups of substances, e.g. B. selected from the group of plastics or metals, so that the at least two receiving body have corresponding elasticity properties.
  • the receiving body of the cartridge are made in a spray / casting process of plastics.
  • a polypropylene (PP) is used for the first receiving body with the larger receiving space
  • a polyethylene (PE) is used for the at least one further receiving body with the smaller receiving space.
  • the entire cassette may also be made of a material, such as polyamide (PA), wherein the material variation of the receiving body, for example, by means of the use of aromatic or non-aromatic polyamides.
  • PA polyamide
  • at least one of the receiving body with reinforcements such.
  • a metal mesh or glass fibers be provided in order to achieve the desired elastic properties of the receiving body to each other ..
  • the receiving body made of metals or metal hybrids, wherein the receiving body correspondingly have different elastic properties.
  • the first receiving body made of a metal and the at least one further receiving body made of a plastic.
  • the receiving bodies are connectable to each other or are connected together in the manufacture of the cassette.
  • the material of the first receiving body has a higher modulus of elasticity than the material of the at least one further receiving body, with which the first receiving body has a lower elasticity than the at least one further receiving body and the cassette is easy to produce.
  • protruding reinforcing elements are provided on the first receiving body from the outside thereof, whereby the first receiving body has a lower elasticity than the at least one further receiving body and the cassette is easy to produce.
  • the reinforcing elements preferably comprise ribs which can be easily formed with the first receiving body, in particular in a casting process or an injection / casting process.
  • the reinforcing elements are provided along the entire longitudinal extent of the first receiving body.
  • the reinforcing elements extend over the entire longitudinal extent of the first receiving body.
  • a plurality of reinforcing elements are advantageously arranged uniformly distributed on the outside of the first receiving body.
