Definitions

  • the invention relates to a cap with a sealing washer for a container closure for use in a container with an opening delimited by a peripheral edge, the sealing washer consisting of several layers, of which the lowermost layers seal the opening of the container tightly before being opened for the first time and releasably with are connected to the uppermost layers of the sealing washer, these uppermost layers being able to form a new temporary closure of the opening of the container.
  • 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 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.
  • a cardboard disc can be placed on the mouth of the container as a sealing element, or possibly clamped in the screw cap, as proposed in DE 94 10 934 U1.
  • the sealing disc can then be ejected through a small closure flap in the screw cap in order to allow the contents to flow out of this closure flap again after being screwed on again. This means that any seal is lost after the first opening and the application options are also limited to undemanding and insensitive products.
  • the film that closes the container contents is often like u. a. in EP 0 717 710 B1 and DE 39 20 324 A1 applied by means of induction sealing.
  • a complete sealing washer is placed, the bottom layer of which forms the sealing layer.
  • a second layer usually made of aluminum, which serves to generate and transfer heat during the induction process and, if necessary, forms additional mechanical protection.
  • the second layer is fixed to the first and is particularly advantageous for heat transfer.
  • further components of the sealing washer are then provided, which remain in the cap when the screw or other twist lock is opened.
  • EP 0 395 660 B1 or EP 0 534 949 B1 provide for the top layer to be designed such that it can be opened by partially not being glued to the induction layer.
  • this non-bonded area is of course very sensitive to the effects of force, especially in the direction of rotation, where there is no resistance due to the lack of bonding. It can therefore happen that destruction or damage occurs here, which in particular gives the unskilled user the impression that the container closure was defective or possibly not tight or was not properly closed. In extreme cases, this process can actually lead to the partial destruction of the sealing layer.
  • the object of the invention is to propose a cap with a sealing washer, in which a more gentle separation of the sealing washer components takes place.
  • the cap has devices for limiting the distance of the uppermost layers of the sealing washer from the underside of the cap in the event that the cap is opened, and the uppermost layers of the sealing washer can be rotated without tack to the underside of the cap and relative to it.
  • the uppermost part of the sealing washer which later forms the reseal part, is only lifted vertically upwards.
  • the vertical upward is parallel or exactly in the axial direction of the opening of the container.
  • a controlled, light connection can be easily adjusted by, for example, a polymer separating layer between the reseal part and the lower layers of the sealing washer. It can be provided in such a way that it is stronger than any rotational motion forces and torques that are nevertheless transmitted, but then yields to this vertical influence of force. This vertical lifting of the upper from the lower layers leaves the top of the lower layers unaffected. They are not shifted or kinked relatively to one another or to each other, but remain unaffected.
  • the screw cap now has a reseal part that is ideally suited for reclosing the container. Now it no longer matters whether and how this reseal part moves, it is simply screwed on again with the screw cap. Despite the lack of gluing, it does not fall out of the screw cap, since it is held in the cap by the mechanical interventions, in particular grooves and beads.
  • the sealing washer has a constant outer diameter across all layers. This means that a single punching device can be used and only one punching process is required. In the prior art it was sometimes preferred because of the sensitivity of the upper layers to arrange outwardly projecting tabs on individual layers, as in EP 0 697 345 A2, in order to counteract this.
  • FIG. 1 shows the area of the opening 11 of a container 10. It can be a bottle, a container for agrochemicals, a container that can be closed to prevent aroma, for example for powdered coffee or the like.
  • the opening is surrounded by a peripheral edge 12.
  • the rim 12 is generally circular.
  • a sealing washer 20 consisting of several layers, which is closed at the top and at the side by a screw cap base body 40.
  • the pane 20 begins with a sealing layer 21.
  • This sealing layer 21 is followed by an induction layer 22, usually made of aluminum.
  • This induction layer ensures that heat generated by induction in the layer 22 is transferred to the sealing layer 21 and this is firmly sealed onto the edge 12 of the opening 11 of the container 10 during the production or packaging process.
  • a layer 23 follows next to the induction layer 22.
  • this layer 23 has, for example, tabs projecting outwards or else a corresponding fold in itself Seize on. In the illustration in FIG. 1, this is indicated by such a projecting fold. In the completely closed state, this fold naturally lies flat and takes up practically no additional space. In practice, there is then no space between the layer 23 and the next subsequent layer 24, the so-called reseal part. The reseal part 24 thus lies directly on the layer 23, possibly on the flat fold of the layer 23.
  • All layers are glued together, the layers 21, 22 and 23 very firmly by means of adhesive layers, since they should not and no longer have to be separated from one another.
  • the layers 23 and 24, on the other hand, are coupled to one another by a relatively easily detachable connection which is in any case easily controllable with regard to their adhesive strength.
  • the total thickness of the layers 21, 22 and 23 is very small in relation to the other container and opening dimensions. Their presence or absence is virtually irrelevant for the process of screwing or pushing the cap 40 onto the container 10. It should be pointed out again that FIG. 1 is in no way to scale here.
  • a fastening device 43 is provided on the screw cap 40, for example an internal thread, which engages in corresponding (not shown) counter-fastening elements of the container 10.
  • the cap 40 can therefore be screwed on here.
  • the groove 41 is just arranged so that the reseal part 24 fits into the bead 42.
  • this reseal part 42 easily reaches this area by means of slight mechanical tension or suitable thermal measures via the slight resistance of the groove 41.
  • the resal part 24 is not even separated from the lower layers 21, 22 and 23 of the sealing disk 20. These still remain together.
  • a phase is indicated schematically in the figure in which the separation between the layers 23 and 24 from one another has just taken place. However, both layers are not twisted against each other, they move away from each other along the axis of the container mouth. The indicated fold begins to set up; in practice, however, manual help will usually be required.
