Definitions

  • the invention relates to a film cartridge and a method for producing a film cartridge.
  • Foil cartridges with one or more chambers containing chemical masses such as putties, sealants or adhesive compounds are known. Such a film cartridge is used in a cartridge holder of a Auspress réelles over which the application of the chemical masses takes place at the desired location.
  • the object of the invention is to provide a simple and inexpensive to produce film cartridge that is reliable and reproducible to open.
  • a film cartridge comprising a film tube enclosing at least one chamber in the circumferential direction and a lid which is separate from the film tube and terminates an axial end of the film tube, wherein at least one first opening is formed in the lid for each chamber via which the chamber is filled with a filling material can be filled, and a closure which closes the first opening.
  • the film cartridge first to produce and then to fill, since the first opening is easy to close even after a separate filling.
  • manufacturing and filling was done in one operation, since the film bag was firmly closed at both ends and thus has no opening through which a filling could be done.
  • the second axial end of the film tube may be closed by a separate from the film tube, connected to this bottom. In this way, it is easy to form a cylindrical chamber of defined volume.
  • the bottom can for example consist of the material of the lid or the film tube and correspond in size and dimensions forth at least approximately the lid.
  • the lid is preferably formed of a stiffer material than the film tube, eg of polyethylene, polypropylene, polybutylene terephthalate or acrylonitrile-butadiene-styrene.
  • the film cartridge may be formed as a multi-chamber cartridge, wherein the various chambers can accommodate different filling materials, which are mixed together only when the material is dispensed.
  • chambers can be filled with different filling materials.
  • the filling materials can form, for example, components of sealants, mortars, coating compositions, paints, foam precursors, adhesives or lubricants. But it is also possible to fill at least two chambers with the same filler material to realize high mixing ratios.
  • Several chambers may be formed, for example, by dividing the film tube by a division in the axial direction into a plurality of chambers, which extend in the axial direction parallel to one another.
  • one or more foil sections which extend in the axial direction parallel to the film tube, can be introduced into the latter and adhesively bonded or welded to the walls of the film tube as well as to each other.
  • the individual chambers are completely separated from each other as long as the film cartridge is closed.
  • chambers can also be formed by providing a further film tube which is arranged in the first film tube, so that the first film tube extends parallel to the second film tube.
  • a thin second film tube lying within the first film tube can accommodate a component that is needed in a much smaller volume fraction in the final mixture than the component in the large outer chamber.
  • the chambers may be arranged coaxially, but the inner film tube may also be offset from the axis.
  • the use of film tubes and subdivisions can also be combined, so that depending on the application, any design of the chambers can be achieved.
  • All chambers preferably extend to the lid, where each chamber has its own first opening. Preferably, all the chambers extend to the bottom.
  • a head portion is provided which is fixedly connected to the lid and which has a provided on a receptacle for a mixer tube for dispensing the filling material discharge opening.
  • the head part is advantageously made of a relatively rigid material, so that the dispensing opening is not deformed during the dispensing of the filling material.
  • the dispensing opening may be closed by a closure (prior to use of the film cartridge).
  • At least one channel for guiding the filling material to the dispensing opening can be formed.
  • one channel per chamber is preferably formed, which advantageously runs separately up to the dispensing opening, in order to prevent mixing of the filling materials of the individual chambers within the film cartridge. Through the channels, the individual components and filling materials are completely separated even before the emergence of the discharge opening even when the film cartridge is opened.
  • connection between the film tube and the lid or bottom and between the lid and the head part can be done by gluing or welding, in particular ultrasonic, laser or thermal welding.
  • Headboard and lid can also be connected by latching or caulking. Of course, a combination of these measures can be used. All compounds are preferably designed so that the chambers are hermetically sealed.
  • a separate from the first opening emptying opening is provided per chamber.
  • This offers various advantages when filling the foil cartridges. For example, it is possible to fill the chamber via the first opening so far that the channel is completely filled up to the dispensing opening with the filling material. This means that the flow can be minimized, since the mixing ratio in multi-component cartridges corresponds directly from the beginning of the desired mixing ratio.
  • one or more foils are preferably provided, such as a composite or monofilm.
  • the films may e.g. consist of one or more layers of polypropylene, polyethylene, polyethylene terephthalate, ethylene vinyl copolymer and / or aluminum.
  • the film is preferably welded or glued to the edge of the opening. For easier removal, it can have a tear-off tab.
  • a metal plate or an injection molded part may be provided, in particular for the filling openings in the head part. These closures are closed with the edge of the opening preferably by gluing or welding.
  • the closure can be placed directly on the respective opening.
  • a film may be designed so that it is removable as a whole and after removal of the film, the emptying opening or the discharge opening completely exposed.
  • a film can also have one or more weakening zones, along which the film tears open in a controlled manner by means of overpressure applied via the dispensing device and defines the dispensing opening or emptying opening in a defined manner.
  • the weakening zone can be produced, for example, very reproducibly by laser ablation.
  • the closure in particular that for the first openings, can be provided, for example, with the material details of the components of the filling material, a batch number or else the expiry date. This can optionally be done by the labeling of the film cartridge.
  • the edge of the first opening and / or the discharge opening may have a conical taper.
  • the rejuvenation serves one To center the filling lance and thus make a denser seal between the filling lance and the edge of the opening.
  • At least one lip is formed at the edge of the first opening and / or the discharge opening.
  • the advantageously circumferentially circumferential lip, or a corresponding ridge serves to strip the filler material from the filling lance when retracting the filling lance so that no filling material is introduced into the filling device. It can also be arranged axially behind one another several lips or ridges in order to strip off the largest possible proportion of the filling material.
  • Coarse or comparatively large fillers can also be used in the individual components of the fillers, since the first opening can be made large enough without problems that such components can be filled in without problems. Also, the size of the channels can be easily chosen so that coarser filler can be used in the filling materials.
  • the outer geometry of the film cartridge can be made the same regardless of the number of components used. In this way, a Auspressêt for different types of filling materials can be used.
  • the dispensing opening can also remain unlocked.
  • the emptying opening is preferably closed by a closure provided with a weakening zone, and when applying the pressing force when inserting a still closed new film cartridge into the dispensing device, the internal pressure exceeds the force necessary to open the weakening zone. In this way, the newly inserted film cartridge is opened automatically and controlled.
  • a throttle effect of individual filling materials can be effected from different chambers, whereby the amount of each issued filling material can be set very accurately. Even flow differences at different rheologies of the individual fillers can be compensated.
  • the foil cartridge is completely finished before it is filled. Any existing floor is already used, so that the chamber with the exception of the first opening and possibly another discharge opening are completely closed.
  • the filling material is then filled into the chamber, which can be done in a different machine than the production of the empty film cartridge. After filling, the first opening is closed, hermetically sealing the foil cartridge.
  • An above-described head part with the receptacle for the mixer tube for dispensing the filling material can be firmly connected to the lid before filling or after filling.
  • the channels between the cover and the head part are filled with the filling material.
  • the filling takes place via the first opening, and this is closed after filling and before attaching the head part.
  • the first opening and / or the emptying opening may remain open, and only the openings (filling opening and dispensing opening) in the head part are closed.
  • a further filling opening is preferably provided in alignment with the first opening in the head part.
  • the filling is advantageously carried out via a filling lance, which is introduced through the first opening into the chamber, wherein a UnterLiteab colllung is made. As the filling level increases, the filling lance is continually pulled back while it is being filled. So a bubble-free filling of the chambers is possible.
  • the filling process can be supported by vacuum or back pressure. This is particularly useful if the channels are to be filled to the dispensing opening.
  • the air in the chambers may escape through the discharge openings (if provided). It is also possible to form the filling opening in the head part with a smaller cross-section than the first opening during filling when the head part is attached, so that the filling lance lies close to the filling opening, but air can escape from the chamber due to the excess of the first opening during filling ,
  • the film cartridge is easy to open because the film used as a closure can be easily peeled off without tools or, with certain force applied to the film cartridge, tears open from outside through the extrusion tool. Since a defined opening always arises, the forces necessary for the application process are constant during the opening and during the pressing out of the filling material.
