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 circumferential 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, wherein these uppermost layers can 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 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.
  • a cardboard disk can be placed on the mouth of the container as a sealing element, as suggested in DE 94 10 934 U1, or possibly clamped in the screw cap.
  • 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. After the first opening, however, any seal is lost and the application options are also limited to undemanding and insensitive products.
  • the film that closes the container content 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 is used to generate and transfer heat during the induction process and, if necessary, provides 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.
  • 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 of an opening of the cap, and the uppermost layers of the sealing washer can be rotated without tack to the underside of the cap and with respect 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, although it is stronger than any rotational motion forces and torques that are nevertheless transmitted, it 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 relative to each other or to each other, but remain unaffected.
  • the screw cap now has a reseal part which is ideally suited for reclosing the container. Now it doesn't matter whether and how this reseal part moves, it is simply screwed back on 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. It is particularly preferred if 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.
  • Figure 1 is a schematic, not to scale, cross section through a screw cap with a sealing washer during opening.
  • 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 sealed 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 initially begins with a sealing layer 21.
  • 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 lies naturally flat and takes up practically no additional space. In practice there is then no space between the layer 23 and the next layer 24 lying thereon, the so-called reseal part. The reseal part 24 therefore 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.
  • a fastening device 43 is provided, 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.
  • Free space is provided for a sealing washer 20, but this free space also has an inwardly projecting groove 41 or coordinated with it Relationship to this groove 41 to the outside slightly projecting bead 42. The proportions are also slightly exaggerated 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.

Abstract

Un bouchon (40) muni d'un disque d'étanchéité est appliqué, plus particulièrement, vissé, sur l'ouverture d'un récipient (10). Le disque d'étanchéité est formé de plusieurs couches, les couches supérieures (24) restant dans le bouchon, lors d'une ouverture, et les couches inférieures (21, 22, 23) étant scellées sur l'ouverture du récipient. Les couches supérieures peuvent être utilisées pour refermer le récipient ; elles ne sont pas collées sur le bouchon fileté. Lorsque le récipient est ouvert pour la première fois, elles se détachent des couches inférieures et se soulèvent verticalement vers le haut, supprimant ainsi tout risque d'endommager la partie supérieure des couches inférieures.
