Bottle cap

Abstract

The invention relates to a closure cap to be placed on the neck of a drinks bottle. The invention has the object of providing a closure cap which bears as a closure seal against the top of the bottle neck. According to the invention, this is achieved by an upper breakthrough in the closure cap. into which an internally inserted disc-like decorative item engages. the closure cap having at least in part a retaining bead that runs parallel to the top of the closure cap and projects into the cap. into which retaining bead are inserted a liner plate also running parallel to the cap top and the decorative item engaging in the top. This liner plate secures the decorative item in the position in the top of the closure cap and bears as a closure seal against the top of the bottle neck.

Description

[0068] The invention will be described by way of example below with reference to drawings, in which

[0069] FIG. 1 shows a perspectively sectioned illustration of the closure cap 1 with the functional components arranged in the closure cap 1, in an exploded illustration;

[0070] FIG. 2 shows a perspective view of a closure cap 1;

[0071] FIG. 3 shows a top view of the top side of the closure cap 1;

[0072] FIG. 4 shows the closure cap 1 in a side view;

[0073] FIG. 5 shows a section through a constructional form of the closure cap according to the invention with a decorative item 5 and a liner plate 7;

[0074] FIG. 6 shows a decorative item 5 in a sectioned illustration;

[0075] FIG. 7 shows a bottom view of the decorative item 5;

[0076] FIG. 8 shows a top view of a decorative item 5, and

[0077] FIG. 9 shows a section through a further embodiment of the closure cap 1 according to the invention.

[0078] FIG. 1 shows the arrangement of the functional components of the closure body 5, of a carrier 6 with a memory medium 8 and of the closing liner plate 7 in an exploded drawing and arranged in a sectioned closure cap 1.

[0079] It becomes clear here that an opening 3 is provided in the top side of the closure cap 1, through which opening the decorative item 5 partially emerges from the closure cap 1. In this embodiment, a carrier 6 in disk-like form, on which a memory chip 8, in this case an NFC chip, is arranged between the decorative item 5 and the closing liner plate 7. This memory chip 8 is accordingly used between the closing decorative item 5 and the inner liner plate 7.

[0080] Next to the top-side opening 3, the closure cap 1 has a special formation below the top side 2 of the closure cap 1. This embodiment involves a retaining bead 4 which is arranged in an encircling manner annularly below the top side 2 of the closure cap 1. Said retaining bead 4 is arranged offset in its depth on the shell of the closure cap 1 in such a manner that the package of the functional elements-the decorative item 5, the carrier 6 and the liner plate 7-is accommodated in terms of the thickness thereof in the head of the closure cap 1 entirely above said retaining bead 4.

[0081] The retaining bead 4 is arranged here embossed inward in the closure cap 1 and is cut in at such a depth that the liner plate 7 has to be pushed over said retaining bead 4, and, after elastic deformation of the liner plate 7, the retaining bead 4 is located below the liner plate 7 and fixes the latter in its position in the head of the closure cap 1.

[0082] FIGS. 2 to 4 now show an exemplary closure cap 1 of this type, as could be applied, for example, to a wine bottle. It can be seen here in the various views that the central region of the decorative body 5 emerges from the closure cap 1 on the top side and in raised form. Said central region is higher, by means of a step 11 which is illustrated in FIG. 6, than the encircling edge 9 of the decorative body 5, which encircling edge 9 is likewise illustrated in FIG. 6.

[0083] This becomes particularly clear in FIG. 4 where the decorative item 5 can be seen above the surface 2 of the closure cap 1. The retaining bead 4 can also be seen here in the figures, said retaining bead 4 running below the top side 2 of the closure cap 1 and fixing the functional elements of the decorative item 5 and at least of the liner plate 7 in the head of the closure cap.

[0084] FIG. 5 illustrates a constructional form of the closure cap 1 sectioned in the upper region thereof. It also becomes clear here that the retaining bead 4 is arranged in the shell of the closure cap 1 in order to fix the combination of liner plate 7 and decorative item 5 in position. Also illustrated here is a bottleneck 16 on which the closure cap 1 has already been embossed in this case, and therefore the bottleneck thread 15 can be seen here. In this embodiment, the retaining bead 4 is located above said thread and thus has the effect that the liner plate 7 is fixed above the bottleneck 16 on which the liner plate 7 sits firmly, when, for example, a wine bottle is closed, and thus seals the bottle.

[0085] It can be seen in this embodiment that the decorative item 5 is not designed as an item with a flat, planar surface, but rather a step 11 is provided here, as can also be seen in detail in FIG. 6. The decorative item 5 is indicated here by a lower side which, in the present constructional form, has a gently extending depression 12. This depression is used to spatially receive an NFC memory chip 8 possibly arranged between the liner plate 7 and said decorative item 5. The effect here is intended to be that a pressure is not exerted on said NFC memory chip 8 to an extent which could impair the functionality of the memory chip 8 or destroy the latter.

[0086] The decorative item 5 in this exemplary constructional form has a peripheral flattened edge region 9 which is raised toward the center via a step 11 to a higher level in the center plane 10. This is the region which is intended to emerge from the opening 3 in the top side 2 of the closure cap 1. The encircling edge region 9 engages here behind the top side of the closure cap to the side of the opening 3 and thus fixes the decorative body 5 in the opening 3.

[0087] FIGS. 7 and 8 firstly show the view of the lower side of the decorative body 5 with the gentle depression 12, as the latter has already been explained with regard to FIG. 6. In addition, the top view in FIG. 8 shows the raised central region 10 and the flattened edge region 9 of the decorative body 5, which regions are connected to each other via the inclined step 11. This flank 11 here can assume different height dimensions, this in particular being a matter of visual appearance, since this determines by how much the central region 10 emerges from the opening 3 in the top side 2 of the closure cap 1.

[0088] FIG. 9 now shows a further variation in which the description with regard to FIG. 5 continues to be largely applicable. However, added to this is a modified design of the top side 2 of the closure cap 1, since this now likewise has a further step 13, as a result of which the top side 2 has a flatter edge region which is raised by means of the step 13 to a higher ring region 14 which leads into the opening 3. That is to say, there is a raised ring region 14 starting from the opening 3, said ring region 14, in the illustrated configuration of the invention, receiving the flattened edge region 9 of the decorative body 5.

[0089] The advantage of this constructional form resides in the fact that the position of the decorative item is once again integrated here more exactly in said corresponding receptacle in the top side 2 of the closure cap 1 since the liner plate 7 at the edge region of the top side 2 of the closure cap 1 bears directly against the latter and the decorative item 5 is likewise fitted into the top side 2 in a completely precisely fitting manner.
