Definitions

  • the invention relates to a cartridge with at least one longitudinally extending receiving chamber for a medium to be discharged, and a multi-component cartridge according to the preamble of the respective independent claim.
  • one-component systems in which the material to be discharged consists of only one component
  • two-component or multi-component systems in which at least two different components are stored in separate chambers of the same cartridge or in separate cartridges, the components being discharged by means of a dynamic or a static mixing device are intimately mixed.
  • examples include two-component adhesive or chemical dowels that cure only after mixing the two components.
  • two-component systems are also used for paints, which are often used for the production of functional protective layers, for example for corrosion protection.
  • the cartridges comprise one or more axially displaceable delivery pistons, by whose movement the material is discharged from the chamber or the chambers.
  • the chambers must have sufficiently thick walls in order to withstand the pressure arising during discharge can.
  • the cartridges must have sufficiently thick walls to be sufficiently diffusion-tight. This is particularly important with regard to storage, in order to effectively prevent the inward diffusion or outward diffusion of the chemical substances and thus a degradation of the cartridge contents. Since such plastic cartridges are usually designed for single use, resulting from both the volume and the mass of a significant amount of waste that must be disposed of, which is particularly disadvantageous from aspects of environmental protection.
  • the object of the invention solving this object are characterized by the features of the independent claim of each category.
  • a cartridge is proposed with at least one longitudinally extending receiving chamber for a medium to be discharged, with a head part and a cartridge wall, which limit the receiving chamber, wherein a piston is provided, which is inserted at the end facing away from the head part in the receiving chamber and sealingly displaceable along the cartridge wall in the longitudinal direction, and wherein the cartridge wall is made of a cardboard and is sealingly connected to the head part.
  • paperboard also includes paperboard composites.
  • the cartridge according to the invention offers the advantages of a conventional cartridge in terms of its filling and storage life, so it does not have to be filled in elaborate filling devices, as is generally required for hoses, and can be much simpler be stored, for example, standing.
  • the piston provided for discharging the medium from the receiving chamber has the advantage that, as a rule, smaller residual bulk volumes remain in the cartridge, as a result of which the amount of waste is reduced. Furthermore, chemical agents in the receiving chamber minimize the risks associated with the chemistry of the individual unreacted components.
  • the piston is preferably designed as a valve piston or self-venting piston, so that a simple venting during insertion of the piston is possible.
  • the head part is made of a cardboard.
  • the cartridge wall or the head part - particularly preferably both - comprise a film which is provided on the surface of the cartridge wall or the head part delimiting the receiving chamber and which is inseparable from the cartridge wall or with connected to the headboard.
  • the film provides a very efficient diffusion barrier, so that no concessions to the shelf life or the maximum storage time are necessary. Even with longer storage times, the contents of the cartridge are effectively protected against the exudation or diffusion of substances or "outgassing".
  • the cartridge wall or headboard is protected by the film, e.g. when the cardboard material of the cartridge wall is sensitive to the medium in the receiving chamber.
  • the film has a very high flexibility with regard to the choice of material and can be adapted to the specific cartridge content depending on the application. Another advantage of the film is that it reduces the friction between the cartridge wall and the piston when discharging the medium.
  • the cartridge wall in comparison to conventional cartridges, because the wall thickness is no longer needed as a means for preventing or reducing diffusion-related degradation processes.
  • the cartridge wall has a wall thickness of at most 1.0 mm, preferably of approximately 0.5 mm.
  • This small wall thickness means in comparison to conventional cartridges a very significant reduction of waste and a reduction of the raw materials required for the production.
  • the cartridge according to the invention is preferably inserted into a reusable support cartridge when discharging its contents, or a dispensing device is used in which the support function is directly integrated.
  • even larger wall thicknesses can be realized as Quick
  • the cartridge wall can also be designed so thick that no support cartridge or the like is necessary for the discharge.
  • the cartridge wall has a second film, which is provided on the outer surface of the cartridge wall facing away from the receiving chamber.
  • This second film can be used, for example, as a protection against mechanical influences or for labeling, in particular to identify the cartridge contents.
  • the film of the cartridge wall or the head part - preferably both - is designed as a multilayer system.
  • the properties of the film serving as a barrier or diffusion barrier can be adjusted in a targeted manner in order to make it as efficient as possible with regard to the medium in the receiving chamber.
  • a multilayer system is configured as a composite film.
  • the multilayer system may also include metallic layers.
  • a dimensionally stable support ring which encloses the cartridge wall at the end of the receiving chamber intended for receiving the piston from the outside.
  • This support ring is particularly advantageous in terms of storage, because it improves the seal between the cartridge wall and the piston.
  • the support ring can be reusable.
  • the support ring comprises an undercut, which supports the cartridge wall with respect to the longitudinal direction. After insertion of the piston in the receiving chamber this is secured by the undercut.
  • connecting means are provided in the cartridge, by means of which the cartridge with a second cartridge is connectable.
  • These connecting means can be designed in particular as a latching or as a click or snap connection.
  • the connecting means are preferably arranged so that the two cartridges are connected side by side connectable side by side, so that their longitudinal directions or longitudinal axes parallel to each other run.
  • connecting means with which the cartridges are connectable so that one cartridge is arranged in the other cartridge, preferably coaxially, so that the longitudinal axes of the two cartridges coincide.
  • the possibility of connecting a plurality of cartridges via the connecting means significantly increases the flexibility with regard to the fields of application, in particular because the cartridges can be used very easily for multicomponent systems.
  • the support ring is suitable for providing connection means there.
  • the head part comprises an adapter having an outlet for the medium.
  • This adapter makes the cartridge particularly flexible in its applications because the adapter can be adapted to work with various accessories without the need for changes to other parts of the cartridge.
  • the adapter is preferably made of plastic - in particular injection-molded - and connected to the head part. This compound can be solvable or insoluble.
  • the adapter and headboard may also be integral, for example produced in a single injection molding process.
  • the adapter can be glued, for example, after its production in an injection molding on the headboard or welded thereto or molded onto the head ..
  • the adapter is then a separate component whose design and / or placement without changes to the Remainder of the cartridge is adaptable to the particular application.
  • the head part of the cartridge with the surface completely closed towards the outside-ie initially without an outlet for the medium-so that the medium in the receiving chamber can not escape to the outside and is protected during storage.
  • the adapter which includes the outlet, is placed on the header, with the outlet not yet having fluid communication with the receiving chamber. Only for the application is then pierced through the outlet through the head of the cartridge, so that the medium can escape through the outlet.
  • the invention further proposes a multicomponent cartridge having at least two cartridges, of which at least one cartridge is designed according to the invention, wherein the two cartridges are arranged side by side with respect to the longitudinal direction, or wherein the two cartridges are arranged one inside the other, preferably coaxially, so that one cartridge the other cartridge encloses.
  • the first variant involves so-called side-by-side cartridges in which the two receiving chambers are arranged side by side.
  • the two cartridges are arranged inside each other, so that the cartridge wall of the outer cartridge completely surrounds the cartridge wall of the inner cartridge.
  • the inner cartridge is centered in the outer cartridge, so that their longitudinal axes A coincide. This is referred to as coaxial cartridges.
  • the two cartridges are firmly coupled to each other via the connecting means, so that the multi-component cartridge forms a storable and dischargeable unit.
  • a particularly advantageous measure is when the adapters of the cartridges for interaction with an accessory, in particular with a mixer, are arranged and configured. In this way it is possible, for example, to use per se known accessories in conjunction with the multi-component cartridge. This compatibility is advantageous for practical and economic reasons
  • the multicomponent cartridge comprises a mixer adapted to cooperate with the adapters and having two piercing elements, each of which can engage in an outlet to open a flow communication with the respective receiving chamber.
  • the receiving chambers of the two cartridges may have different volumes, so that in particular mixing ratios between the two media contained in the receiving chambers of the cartridges can be realized, which differ from the ratio 1: 1.
