Definitions

  • the invention relates to a sealing washer and a film composite for a container closure for use in a container with an opening delimited by a peripheral edge, the film composite consisting of several layers and an adhesive layer being arranged between the upper layer and the layer below it at least over a partial surface.
  • the container closure is then closed with a screw cap or a similar element, which ensures the mechanical and stable closure outside the film.
  • the user destroys the film in order to access the contents of the container and then closes the container (if he has not yet removed all of the contents) with the screw cap, which can temporarily seal the opened contents for a correspondingly short period of time.
  • the adhesive layer is in any case provided in the region of the upper layer which forms the fold.
  • contact is made in this area from adhesive layer to adhesive layer within the fold, which enormously increases and improves their stability and firm adherence, which has a corresponding effect on the tear and tensile strength and also prevents the fold from bulging or possibly due to external influences rises oval.
  • the total area of the sealing film is slightly larger than the opening to be covered, including the peripheral edge.
  • the object is achieved in that the lower layers of the sealing washer have the film composite according to one of the above combinations of features.
  • a container 10 is filled, for example, with food or agrochemicals or other oxygen-sensitive goods, in particular with liquid. It has an opening 11 from which the content is to be removed in due course. The opening 11 is surrounded by a peripheral edge 12.
  • the film composite 30 has in particular three film and two adhesive layers. This can be clearly seen in FIG. 2.
  • the bottom layer 34 is fixed in the sealed state exactly on the peripheral edge 12 of the container 10.
  • An adhesive layer 35 is arranged on the first or lowest layer 34, which firmly connects this first layer 34 to a second layer 31.
  • the second layer 31 is an induction foil, in particular made of aluminum. If it is heated by induction, this heat is transferred to the lowermost layer 34 and thus seals it on the edge 12.
  • the fold 40 extends perpendicular to the image plane across the film.
  • the distance between pleat foot 41 and pleat tip 42 is constant, possibly with bevels or curves in the edge area.
  • the fold tip thus forms an essentially straight line.
  • FIG. 1 it can be seen how this affects overall.
  • the entire container mouth or opening 11 of the container 10, which is covered by the film composite 30, is at the same time provided just eccentrically with the fold 40 which rises upwards from the fold foot 41 lying exactly in the plane of the opening 11 of the container 10.
  • the fold 40 is shown slightly oblique, which is due to the fact that it lies completely flat in the packaged state, thus taking up little space and also offering no reason to be gripped by the screw cap when screwing on.
  • the upper part can be a polyamide layer or another polymer.
  • the sealing layer below the aluminum induction film layer 31 is adapted to the respective material of the container.
  • the fold 40 is not formed until the punching process.
  • a corresponding apparatus of a punch measuring apparatus turns out that the full-surface material runs in folded accordingly.
