Definitions

  • the invention relates to a sealing washer with a grip tab.
  • Sealing disks are known in various embodiments (DE 1 482 575, EP 0 148 527 B1, GB 2 142 911 A, US 4,266,687). They are designed as thin discs with a grip tab and a special thermoplastic coating for heat welding using induction technology. The sealing washers are applied to a container and connected to the upper edge of this container. By means of the grip tab, they can be pulled off the edge of the container again if the container is to be opened. The grip tab is arranged so that it is not connected to the edge of the container during heat welding.
  • the invention has for its object to provide an improved sealing washer with tab.
  • the peculiar shape of the sealing washer also has a decorative, aesthetic value. Due to the possibility of manufacturing in different dimensions and shapes, individual adaptation to customer requirements is possible without additional technical effort.
  • a sealing washer with a grip tab is provided for peeling a container by gluing, welding or the like of the surface of the sealing washer pressed against an edge of the container by means of a closure, in particular by induction or heat welding, the support tabs for creating a good fit of the grip tab has in the closure and retaining tabs for additional securing of the sealing washer in the closure.
  • the support tabs are tabs, which are usually arranged next to the handle tab and support the handle tab which does not engage in the lock. For this purpose, they engage in a groove, holding bead or the like provided in the closure or in a screw groove in the internal thread of the closure.
  • the diameter of the mostly round sealing washers essentially corresponds to the inside diameter of the internal thread inside the closure.
  • the retaining tabs are usually arranged on the side of the sealing washer opposite the handle tab and the support tabs. They provide further protection of the sealing washer in the closure of the container. As many tabs are advantageously provided as handle tabs and support tabs are provided, for example three retaining tabs with two support tabs and one handle tab. Retaining tabs and support tabs together replace the above-mentioned larger diameter of the known sealing washers.
  • the grip tab extends beyond the groove or retaining bead or the screw groove of the internal thread of the closure. It attaches to the internal thread and is held in place when the cap is screwed on.
  • the sealing washer is inserted into the closure when the closure is screwed onto the container placed on its edge.
  • the sealing disk is then either heated together with the edge of the container. Or it is glued to this edge by pressing the surface of the sealing disk facing the edge of the container and previously applying an adhesive to this edge.
  • the sealing washer is connected to the edge of the container by means of its thermoplastic coating. If the sealing disc is to be removed from the container when it is opened, it can be pulled off or peeled from the edge of the container by means of the grip tab. This is also possible if the sealing washer is attached to the edge of the container by gluing and pressing.
  • the container 1 shows an exploded perspective view of a container 1 with a sealing washer 2 according to the invention and a closure 3.
  • the container 1 has an external thread 5 at its upper end 4. This ends in an upper edge 6.
  • the sealing disc 2 can be attached to this upper edge 6.
  • the sealing washer 2 is essentially round. Its diameter corresponds essentially to that of the upper edge 6 of the container 1.
  • the sealing disk 2 has different tabs 8, 9, 10.
  • the tab 8 is one Grip tab. It is shaped as an elongated tab with a rounded end 11. The grip tab 8 is so large that the sealing washer 2 can be removed from the closure 3 or from the upper edge 6 of the container 1 by pulling or pulling it off.
  • the tabs 9 are support tabs. There are two support tabs 9a and 9b in FIG. These are arranged next to the grip tab 8. The ends of the tabs 8, 9a, 9b adjoining the outer edge 7 of the sealing disk 2 directly adjoin one another and merge into one another.
  • the transition region 12 has a rounded shape in order to avoid the notch effect and the resulting risk of the tabs tearing in or tearing off when it is pulled off the edge 6 of the container 1 or when the sealing disk 2 is pulled out of the closure 3.
  • the support tabs 9a, 9b support the sealing washer 2 in the closure 3. This means that they engage in an internal thread 13 provided on the inside of the closure 3 or in a groove (not shown) provided there.
  • the support tabs 9a, 9b have a length corresponding to or adapted to the depth of the internal thread 13.
  • the width of the support tabs 9a, 9b can be selected variably. A secure fit of the sealing washer 2 in the closure 3 should be made possible.
  • the tabs 10 are holding tabs. They are arranged on the side of the sealing disk 2 opposite the support tab and the grip tab. In Figure 1, three retaining tabs 10a, 10b and 10c are provided. The holding tab 10b is arranged exactly opposite the grip tab 8. The two other retaining tabs 10a, 10c are arranged next to the latter at an acute angle to the center of the sealing disk 2.
  • the retaining tabs 10 can also be provided in a different arrangement or number. Since they are provided for additional protection of the sealing washer 2 in the closure 3, they should be so be dimensioned and arranged so that this is granted. In most cases, the holding straps 10 have a size corresponding to the supporting straps 9. In contrast, the grip tab 8 is usually larger, as is also the case in FIG.
  • the sealing washer 2 is first inserted into the closure 3. Both the support tabs 9a, 9b and the retaining tabs 10a, 10b, 10c engage in grooves 14 in the internal thread 13. The grip tab 8 does not engage in the grooves 14, but protrudes beyond them and possibly lies against them.
  • the closure is then screwed onto the upper end 4 of the container 1 provided with the external thread 5. If the sealing washer 2 is to be connected to the edge 6 of the container 1 by means of heat welding. the container 1 with the closure 3 is exposed to the corresponding heat in the screwed-on state.
  • the connection of the sealing washer 2 and the edge 6 is improved in that an only indicated circumferential linear pressure surface 15 in the closure 3 presses the sealing washer 2 against the edge 6.
  • the tabs 9, 10 projecting into the internal thread 13 of the closure 3 and the grip tab 8 are not connected to the edge 6 during the welding. Instead of heat welding, the sealing disk 2 and the edge 6 of the container 1 can also be glued to one another or otherwise connected to one another. An adhesive is then applied to the edge 6 before the closure 3 is screwed on.
  • the edge 6 of the container 1 and the sealing washer 2 are not firmly connected to one another.
  • the sealing disk 2 arranged in the closure 3 nevertheless seals the container 1 when the closure 3 is screwed onto the container 1.
  • the sealing effect is among others depending on the material selected for the sealing washer, for example aluminum-coated polypropylene or polyethylene.
  • the sealing washer 2 shows the sealing washer 2 according to FIG. 1 in a top view. Their essentially round shape is recognizable. However, the sealing washer 2 can also have an oval, rectangular or any other shape. The choice of shape is only dependent on the shape of the edge 6 of the container 1.
  • the sealing disc appears turtle-shaped.
  • the tabs 8, 9, 10 are arranged so that the longer handle tab 8 can be viewed as the head, the support tabs 9a, 9b and the retaining tabs 10a, 10c as legs and the middle retaining tab 10b as tails of the turtle.
  • the sealing washer 2 is also given an aesthetic value. This can also be taken into account for advertising purposes, for example in the case of foodstuffs intended for children in containers.
  • FIG. 3 shows a perspective view of a closure 3 with a sealing washer 2 according to the invention in a second embodiment.
  • the closure 3 is shown partially cut away.
  • the sealing washer 2 is supported in a groove 16 arranged above the internal thread 13.
  • the support tabs 9 and the retaining tabs 10 engage in this groove 16.
  • the grip tab 8 is bent downwards and lies against an outer wall 17 of the closure 3.
  • the grip tab 8 clamped between this outer wall 17 and the wall of the container 1.
  • the two support straps 9a, 9b are arranged further away from the grip tab 8 in FIG. 3 than in the two previous figures. As a result, they are essentially mirror images of the two laterally arranged retaining tabs 10a, 10c.
  • FIG. 4 shows the sealing washer 2 according to FIG. 3 in a top view.
  • the arrangement of the support straps 9a, 9b and the side retaining straps 10a, 10b in the form of a game can be clearly seen.
  • the longer holding tab 8 is arranged opposite the middle holding tab 10b.
  • the round shape predominates in this embodiment of the sealing washer 2.
  • the grip tab 8 emerges from this actually uniform shape.
  • the sealing disk 2 shown in FIG. 4, as well as the one shown in the previous figures, has an upper side facing the closure 3 made of a coated plastic, for example polypropylene or polyethylene with a coating of polypropylene or wax, and an underside facing the container.
  • the underside is either made from a metal coated with wax or the like or from a metal coated with a thermoplastic acting special lacquer, for example coated aluminum. If the sealing washer 2 is to be glued on or attached by pressing on the edge of the container 1, the metal is merely coated with a conventional lacquer which can be connected to the adhesive.
  • FIG. 5 shows a plan view of a third embodiment of a sealing washer 2 according to the invention.
  • this has a greatly reduced grip tab 8. It is dimensioned the same size as the two lateral holding tabs 10a, 10c.
  • the three tabs 8, 10a, 10c are arranged at an angle of approximately 120 ° to one another.
  • the other three tabs, the support tabs 9a, 9b and the retaining tab 10b, are also offset by 60 ° to the three first-mentioned tabs 8, 10a, 10c at an angle of approximately 120 ° to one another.
  • the three tabs 8, 10a, 10c are dimensioned larger than the other three tabs 10b, 9a, 9b.
  • the round shape of the sealing washer 2 is even more apparent than in the embodiment in FIG. 4.
  • the grip tab 8 can no longer be recognized as such, since three larger tabs are provided.
  • each of the three tabs 8, 10a, 10c can be engaged and pulled. All six tabs 8, 10a, 10c and 9a, 9b, 10b engage in the internal thread 13 or the groove 16 of the closure 3. Additional cutouts can be provided in the groove 16 of the closure 3 for the larger-sized tabs 8, 10a, 10c so that they are not welded to the edge 6 of the container 1 during heat welding.
  • FIG. 6 shows a fourth embodiment of a sealing washer 2 according to the invention in plan view.
  • the sealing disk 2 has only the grip tab 8 and the two lateral retaining tabs 10a, 10c, but no central retaining tab 10b and no supporting tabs 9a, 9b.
  • the holding tabs 10a, 10c thus take over the supporting function of the supporting tabs 9a, 9b and hold the sealing washer 2 firmly in the closure 3.
  • they are dimensioned essentially the same size as the handle tab 8 and arranged at an angle of approximately 120 ° to it.
  • the grip tab 8 can also be dimensioned a little larger.
  • the sealing disks 2 of all the embodiments mentioned can be produced in different sizes and also in different intermediate variants.
  • the respective shape and size depends on the shape and size of the container 1 and the closure 3 and on the desired aesthetic impression that is to be connected to the sealing washer 2.
  • Printing can be provided on the top of the pane 2, for example the product or manufacturer name.
  • a colored coating is also possible. This is particularly useful, for example, for the turtle shape in Fig. 2.
