CONTAINER HAVING A SEALING CAP AND A TEAR-OFF RING

Abstract

The invention relates to a container (1) having an opening (9) and an opening section (10), which extends in a cylinder shape, proceeding from the opening (9), which container comprises a sealing cap (3) that is removably fixed to the container (1) and seals the opening (9) when in a closed position and has a substantially cylindrical shell surface (30), which encloses the opening section (10) at least in part when in the position. Interacting latching elements (17, 34) are provided on closed position. Interacting latching elements (17, 34) are provided on an inner surface of the shell surface (30) of the sealing cap (3) and on an outer surface of the opening section (10). A peripheral protrusion (13) is provided below the latching elements (17, 34) in the opening section (10). A ring (5) is peripherally connected on the top edge (50) thereof to the shell surface (30) of the sealing cap via a tear-off skin (7). The tear-off skin (7) contacts the first protrusion (13) of the originally sealed container.

[0041] FIGS. 1 and 2 show an embodiment of the container 1 with a sealing cap 3 attached thereto and a ring 5 connected to the sealing cap. The container 1 is formed here as a cylinder. On its mouth section 10, which is at least partially covered here, cf., e.g., FIG. 3, the sealing cap 3 and the ring 5 are seated. The sealing cap 3 has a shell surface 30. The upper edge 50 of the ring 5 is circumferentially connected to the shell surface 30 via a tear-off film 4. The shell surface 30 has a knurling 31 and an opening tab 32. The ring 5 has a predetermined breaking point 52 and, close to it, a grip element 51, which additionally has a marking in the form of an arrow indicating the preferred pulling direction. A predetermined breaking point 52 is configured as a material thinning 53.

[0042] FIGS. 3, 4 and 5 show an embodiment of the container 1 with the mouth section 10 and an opening 9. In the mouth section 10 there is the mouth-section-side portion of first latching elements 17, which here are designed as a snap bead 11 which has an opening section 12, a first circumferential protrusion 13, a sealing surface 14 above the snap bead 11, and a second circumferential protrusion 15. Furthermore, an indicator 16 indicates the position of the opening section 12.

[0043] FIGS. 6 and 7 show the sealing cap 3 and the ring 5 from a frontal view, wherein the shell surface 30 of the sealing cap 3 is connected to the upper edge 50 of the ring 5 via a tear-off film 7. Furthermore, shown are the opening tab 32, the grip element 51, the predetermined breaking point 52, which is formed as a material thinning 53, and the knurling 31.

[0044] The sealing cap 3 and the ring 5 are shown in FIGS. 8 and 9 at an angle from below and in FIG. 10 in a cross-section through plane B (cf. FIG. 6). With respect to the figures already described, it can also be seen here that the sealing cap has shell-surface-side first latching elements which are formed as an inwardly protruding snap bead 34 which is divided into an opening bead 35 and a retaining bead 36. It can be seen that the retaining bead 36 is larger than the opening bead 35 and extends over approximately one half of the circumference of the shell surface 30 opposite the opening bead 35, cf. also FIG. 12, the retaining bead 36 having an interruption 37. Furthermore, it can be seen that the sealing cap 3 has a holder 38 on its side 4 facing the container 1 in the closed position, for example for a desiccant tablet. Furthermore, the sealing cap 3 has a sealing cam 39 which is formed above the first latching elements 33. Furthermore, on its inner side, the ring has a protrusion 54 which, in the closed position before ring 5 is torn off, is in a latching connection with the second preferably circumferentially extending protrusion 15 of the container.

[0045] FIGS. 11 and 12 show the sealing cap 3, wherein the ring 5, which is not shown, has been torn off. In particular, the shell-surface-side first latching elements 33 can be seen, which are formed as an inwardly protruding snap bead 34 consisting of an opening bead and a retaining bead 36. The retaining bead 36 is larger than the opening bead 35 and extends over approximately one half of the circumference of the shell surface 30 that is situated opposite the opening bead 35. The retaining bead 36 has an interruption 37.

[0046] FIGS. 13 and 14 again show an embodiment of the container 1 and the sealing cap 3 attached to container 1, from which the ring 5 has already been removed. The sealing cap 3 includes the opening tab 32 and the container 1 includes the indicator 16. In FIG. 13, the sealing cap 3 is in a position relative to the container 1 in which the sealing cap 3 cannot be removed from the container 1. In FIG. 14, however, the sealing cap 3 is in a position relative to the container 1 in which the opening tab 32 is aligned with indicator 16 and the sealing cap 3 can therefore be removed from the container 1.

[0047] FIG. 15 shows an embodiment of the container 1 with the sealing cap 3 and the ring 5 in a cross-section along plane A (cf. FIG. 1). The container includes the snap bead 11 with the interruption 37, the first protrusion 13, the second protrusion 15, the indicator 16, the sealing surface 14 and a holder 38. The substantially cylindrical holder 38 in this embodiment has a holding element 40 in the form of a circumferential hook-shaped latching element. Thus, a desiccant in tablet form can easily be inserted into the holder 38, in which it is then reliably secured via the holding element 40.

[0048] The sealing cap 3 has a shell surface 30 with a sealing cam 39 which rests on the sealing surface 14. Preferably, there is a pretensioning force by which the sealing cam 39 is pulled onto the sealing surface 14, the protrusion 54 on the inside of the ring 5 is pulled against the second protrusion 15 of the container and/or the tear-off film 7, which is configured as a sealing film, is pulled onto the first protrusion 13.

[0049] The exemplary embodiments illustrated in the figures and explained in connection therewith serve to explain the invention and are not limiting the same.
