Definitions

  • the invention relates to a container made of glass, ceramic or plastic with a screw or slip lid, in which the container opening located under the lid is closed by a tearable or tearable film membrane which is sealed to the edge of the opening via a sealing layer and for opening or opening Tear off is provided with a tear tab.
  • Containers with such a sealed film membrane are known for use in food and beverages, for example coffee powder (e.g. EP 0 148 527).
  • the sealed film membrane is provided for the aroma-tight closure of the container opening and also as a guarantee of originality for the container contents.
  • they are provided with a sealing layer made of plastic.
  • the membrane membrane is sealed to the edge of the container opening in two different ways.
  • One method is to seal the film membrane placed on the edge of the container opening using pressure and heat before putting the lid on.
  • sealing is done by inductive with the lid already in place Heating of the sealing layer is carried out, for which the film membrane must be provided with a metal layer and the necessary contact pressure is exerted by the attached lid.
  • the metal layer is usually desirable anyway for reasons of aroma tightness and is normally part of the membrane.
  • the inductive sealing has the advantage that it can be done within a very short sealing time within the filling process with the lid already in place.
  • the known metal foil membranes often have a punched or attached tear-open tab, which also has the same film structure as the membrane itself or is formed in one piece with it, there is the problem with these membranes that the metal-containing tear-open tabs influence the induced eddy currents in the inductive sealing in such a way that an uneven heating of the sealing layer and thus an uneven and therefore unsatisfactory sealing takes place.
  • the inductive sealing of containers with film membranes has so far been unproblematic only in those containers in which the film membrane has no tear-open tab. Such a pull tab is desirable for quick and easy opening of the tamper-evident closure.
  • the invention has for its object to provide a container with a film membrane of the type mentioned, which is designed so that a perfect inductive sealing is possible in a simple and inexpensive manner despite the provided pull tab.
  • This is achieved according to the invention in that the film membrane is essentially metal-free, that is to say without a metal layer, at least in the region of its tear-open tab. Despite its flap, such a film membrane does not interfere with the inductive sealing.
  • the essence of the invention is therefore to use an essentially metal-free film as a film membrane as a tamper-evident seal instead of a metal film laminate as a sealing membrane with a molded tear tab, which is sealed onto the edge of the container opening with the aid of a separate or sheet-like metal film applied to the film membrane.
  • substantially metal-free is to be understood to mean such a configuration of the tear-open tab of the film membrane that it does not allow any deflections of the induction field which interfere with the perfect sealing function.
  • the film membrane, together with its tear-open tab can be made essentially metal-free.
  • the metal layer necessary for the inductive sealing can be formed by a disk-shaped metal foil arranged above or below the foil membrane, the entire one Contour of the container opening is adjusted, ie follows the edge of the container opening and does not deviate significantly from it. Because only such a metal foil ensures a uniform metal mass in the entire area of the edge of the container opening and therefore leads to a uniform heating of the sealing layer of the film membrane and thus to a uniform sealing.
  • the disk-shaped metal foil can be arranged in the container lid, and it can be pre-fixed with a few swabs of adhesive.
  • a further embodiment of the container according to the invention is possible, in which the film membrane is essentially metal-free only in the area of the tear-open tab, while in its other areas, in which it is precisely adapted to the opening of the container, it has a laminated-on metal film.
  • This metal foil does not affect the inductive sealing in the area of the pull tab, since it is missing in the pull tab and therefore does not deviate significantly from the contour of the container edge.
  • the film membrane can consist of paper or plastic, such as polyester, polycarbonate or the like, or also of cellophane. If, in one of the two aforementioned embodiments, it is connected to a metal layer, it can be laminated, vapor-coated or bronzed with metal, for example with aluminum, for this purpose.
  • the sealing layers which can be used to seal the film membrane or the metal layer to the edge of the container opening or to seal the metal layer to the non-metallic layer of the membrane film, can consist of sealable plastic and can be laminated on, coated or applied by extrusion coating.
  • a sealable or sealably coated plastic film or paper or cellophane with one or more tear-open tabs can therefore be used as the film membrane, which can be placed over the container opening in any manner without appropriate orientation and yet still allows simple and rapid induction sealing within the filling process makes without the need for a special induction sealing head.
  • FIG. 1 to 3 of the drawing three different advantageous embodiments of the container according to the invention are shown in vertical cross section through the container opening with a lid, which are described in more detail below.
  • All three embodiments are a container, the container opening 1 of which can be closed by a screw cap 3 made of plastic, metal or the like placed on its edge 2.
  • a layer 4 of cardboard lying against and covering the cover bottom is placed in the cover 3, onto which an aluminum layer 5, which can optionally be provided with a corrosion protection layer 6 made of plastic.
  • the film membrane 7 with tear-open tab 8 which consists of plastic, e.g. polyethylene terephthalate, or paper and over its entire side facing the edge 2 of the container opening 1, including the tear-open tab 8, with a heat-sealing layer 9 based on plastic, e.g. a thermoplastic ionomer Resin.
  • a heat-sealing layer 9 based on plastic e.g. a thermoplastic ionomer Resin.
  • the film membrane 8 is sealed inductively by means of the aluminum layer 5 to the edge 2 of the container opening 1.
  • this secondary seal located in the cover 3 is formed only by the cardboard layer 4 and the protective layer 6.
  • Beneath this laminate is the non-metallic film membrane 13 extending over the container opening 1 with molded tear tab 8, on the underside of which an aluminum layer 11 is sealed by a sealing layer 10, the contour of which is adapted to the shape and size of the edge 2 of the container opening, ie this Edge follows and does not protrude beyond this edge as the tear tab 8.
  • a further sealing layer 12 is applied to the underside of the aluminum layer 11, with which the aluminum layer 11 connected to the non-metallic film membrane 13 is sealed onto the edge 2 of the container opening 2.
  • the film membrane with tear-open tab is also made of paper or plastic in this exemplary embodiment and is therefore metal-free, perfect sealing in the induction process is possible despite tear-open tab 8.
  • the tear-open tab 8 is turned up onto the top of the film membrane and thus extends between the film membrane and the cardboard-plastic laminate inserted into the container.
  • a secondary seal in the form of a laminate consisting of a cardboard layer 4 and a plastic layer 6 is inserted into the cover 3.
  • the tamper-evident closure is formed by a non-metallic membrane 14 with a tear-open tab 15, which is sealed to the edge 2 of the container opening 1 via a sealing layer 16.
  • An aluminum layer 18 is laminated onto the top of this film membrane 14 via a sealing layer 17, the contour of which is matched to the corresponding contour of the edge 2 of the container opening 1, ie does not extend over the tear-open tab 15. This ensures that the aluminum layer 18, which is necessary for inductive sealing, does not jeopardize a perfect result of this sealing.
  • the pull tab 15 is folded into a free space 19 which is located between the edge 2 of the container opening 1 and the edge 20 of the container lid 3.
