Definitions

  • the invention relates to a screw cap for liquids, granules, powders, etc. receiving container with a sealing device that fixes the screwed-on lid with ratchet teeth on the flange and only releases the lid by a recognizable change to it.
  • Such rotary lid closures are known per se; they are required in order to offer both the bottler and the user a guarantee that the filled goods correspond in terms of their composition to what was filled into the container by the bottler. On the sealing device or the lid in connection with the sealing device should be recognizable at any time if the container has been opened illegally.
  • a plastic ring is molded onto the lid itself via tearable webs, which breaks off the lid when it is opened without authorization and then falls off. A less-trained or careless user may not notice at all that the container has already been opened illegally because the locking ring simply falls off.
  • the ratchet teeth of the sealing device is provided on a plastic ratchet ring 9 which is clamped between the cover 1 and the base of the flange when the cover 1 is seated on the flange and which is connected to concentric snap ring parts 15 via plastic film connections 17 , which comprise the cover 1, the cover 1 being provided with locking members 7 which reach outwards and have cutting edges 31 which are directed circumferentially between the ratchet ring 9 and the snap ring parts 15 onto the plastic film connection 17.
  • the locking members 7 are triangular in cross section, a first locking member surface 7a falling approximately in the plane in which the film connections also extend.
  • the triangular design of the locking members results in cutting edges on the locking members with which the film connections can be cut in the circumferential direction when the cover is turned.
  • the first locking member surface 7a rests on the ratchet ring 9.
  • the locking members can thus slide over the edge of the locking ring and thus find good guidance.
  • the snap ring parts 15 and the ratchet ring 9 are connected to one another via strong plastic bridges 19 which connect in the unscrewing direction directly to the rest area of the locking members in the wedge-shaped recesses 25. These strong plastic bridges ensure a permanently firm connection between the snap ring parts and the ratchet ring.
  • the snap ring parts injection molded as separate parts and the ratchet ring on the one hand and the cover on the other hand consist of differently colored plastics
  • the snap ring parts 15 encompass the cover edge 5 and the latching locking members 7 are visible between the colors thereof Reach out snap ring parts 17 and ratchet ring 9.
  • the cover is made of black plastic and the sealing device is made of yellow plastic, it becomes very clear if, after turning the locking elements and thus cutting off the snap ring parts, they protrude diagonally and crookedly in front of the black cover compared to a previous system.
  • the lid edge 5 is provided with at least one locking member 7, which is triangular in section and protrudes radially from the lid edge.
  • Fig. 2 shows a sealing device for this lid.
  • This sealing device consists of a ratchet ring 9, which is provided on its inner wall 11 with ratchet 13, which are not shown in detail, since they belong to the prior art.
  • Snap ring parts 15 are provided coaxially with the ratchet ring 9.
  • the cover 1 is injection molded from plastic.
  • 15 film connections 17 are injection molded between the ratchet ring 9 and the snap ring parts, which hold the ratchet ring parts in an undamaged position directly coaxially with respect to the ratchet ring 9.
  • Additional connecting bridges 19 are provided which bring about strong connections between the snap ring parts 15 and the ratchet ring.
  • Fig. 3 shows how the lid 1 and the sealing device according to Fig. 2 are hooked together.
  • the interlocking is achieved in that when the parts according to FIGS. 1 and 2 are brought together axially in the direction of arrows 27, the locking members 7 are inserted through the free spaces 21 into the recess areas 23.
  • the locking members 7 slide with their first locking member surfaces 7a over the upper edge 30 of the ratchet ring into the recesses 25.
  • the locking members 7 are located in the wedge-shaped recesses 25 with their roof-like adjoining second locking member surfaces 7b in the wedge-shaped recesses 25.
  • the rest areas specified by the recesses are located directly next to the plastic bridges 19.
  • the length of the free spaces 21 in the circumferential direction corresponds at least to that of the locking members 19.
  • the cover 1 can, for example, be injection molded from black plastic.
  • the sealing device according to FIG. 2 can be injection molded from yellow plastic. Other color combinations can also be requested and used.
  • the snap ring parts encompass the lid edge 5.
  • the latching locking elements 7 of different colors reach visibly between the snap ring parts 15 and the ratchet ring 9.
  • FIGS. The position and the structure of the film connections are shown in FIGS.
  • the film connections have an approximately 1-shaped cross-section and, as can be seen from FIG. 3, the edge 5 of the cover 1 is inserted into them. If the cover 1 and the sealing device according to FIG. 2 are now rotated relative to one another in the direction of the arrows 29 according to FIG. 3, the cutting edge 31 of the respective locking member 7 cuts through the film connection between the right-hand snap ring part 17 and the ratchet ring 9. This severing is indicated in FIG. 4 by the separation point 33.
  • the snap ring parts 15 now stand out in an arc after being cut off and up, so that the destruction of the sealing device is clearly recognizable.
  • the strong plastic bridges 19 form a permanent connection between the snap ring parts 15 and the ratchet ring 9.
