Description

The invention relates according to the preamble of claim 1, a bottle closure for closing of beverage bottles comprising a cap with a cylindrical shank which extends centrally from the bottom of the cap.

For beverage bottles, the long time usual cork closures are increasingly replaced by made of elastic plastic sealing plug. These allow in addition to their low production costs and the use of capping and filling machines, because such made of plastic sealing plug always ensure a consistent quality.

It has long been known to provide a bottle mouth with an external thread on which a cap is screwed. However, such an arrangement has the disadvantage that the placement of the closure can not be done by a simple printing process, but the cap must be screwed, which is not always guaranteed in the absence of inner plug the tightness of such closures. Screw-on bottle caps are for example in the US 3,074,579 or in the FR 1 030 600 shown.

Furthermore, in known bottle closures, as in DE 26 14 538 or FR 2 306 896 shown to be disadvantageous in that they do not have the typical "pop" effect when opening, which is characteristic for example for champagne bottles.

According to the EP 0 079 552 B is a bottle closure known that gives off a "pop" sound when you open the champagne bottle. In this case, a sealing rib is located at the level of the last course of a multi-threaded thread or beyond the same on the protruding portion. However, the sealing shaft is designed relatively complex. Furthermore, in this bottle closure engagement between the projections on the inner surface of a jacket wall with an external thread of a bottle neck must be ensured.

After DE 30 08 838 For example, a screw cap for a bottle is known with a domed seal shaft that does not have a plurality of sealing ribs. After DE 28 33 099 is a sealing plug made of elastic plastic with the container provided with an externally threaded container mouth cap. The cap is provided on its inside with radially inwardly directed fins. However, this screw is very expensive.

Furthermore, after the EP 0 308 753 A1 a bottle closure for closing of glass bottles of carbonated drinks, in which the integrally formed plastic bottle stopper has a plug-like entering into a bottleneck sealing shaft which extends centrally from the bottom of a cap, the shell wall is provided in its inner surface with an internal thread that with an external thread a bottleneck must be engaged. However, the secure fit on the bottle is achieved in that the closure is brought by the internal thread of the inner surface of the jacket wall in engagement with the external thread of the bottle neck. Since the plastic used in this case of the known bottle closure is relatively hard, the diameter of the inner mouths of the bottle should not deviate greatly from each other, that is, the inner mouths of the bottles must have a low tolerance range, because the sealing shank of the bottle closure is relatively unyielding. However, the manufacturing tolerances of the glass bottles must be compensated by the stem of the bottle cap. Only when the tolerance range at the inner mouths of the bottles is small, the sealing shaft of the Fit the bottle stopper well to the inner mouths to optimally seal the bottle opening.

According to the DE 20 2012 006 881 U1 For example, there is known a bottle closure for capping carbonated beverage bottles which has a plug-like hollow sealing stem centrally extending from the bottom of a cap whose skirt is internally threaded in its inner surface engaging an external thread of the bottle neck can be brought. In this case, the cap of the bottle closure consists of a hard and thus dimensionally stable plastic and the attached hollow sealing shaft made of a soft plastic, so that the latter allows a variable bottleneck inner diameter. The bottle closure consisting of plastics of different properties has to be produced, for example, by a relatively complex two-component injection molding (2K injection molding). For certain applications of bottle caps, the 2K injection molding process still seems advantageous. The disadvantage of such a bottle closure is thus in addition to the relatively complex production in a limitation of usable materials, since a connectivity between the two plastics must be guaranteed and in the case provided external thread of the bottle neck, which brought into engagement with an internal thread of the inside of the jacket wall of the bottle closure must become.

The object of the present invention is thus to provide a bottle closure which overcomes the disadvantages of the above-mentioned bottle caps and can be used in particular in bottles in which the diameters of the inner mouths deviate more from each other. Furthermore, a greater flexibility with respect to the usable materials of the closure is to be achieved. In addition, visual enhancements of the shutter should also be achievable.

The object is solved according to the features of patent claim 1. Accordingly, the invention relates to a bottle closure for closing beverage bottles comprising a cap with a cylindrical shaft which extends centrally from the bottom of the cap, wherein a tubular lamellar seal is stretched on the peripheral surface of the shaft and the lamellar seal at least over a portion A of the length of the shaft extends, the lamellar seal has a plurality of projecting annular, flexible, outwardly formed and concentrically arranged sealing lamellae and the shank at the bottom of the Cap opposite end has a projection which prevents slippage of the plate seal on the shaft in the longitudinal direction. Such a bottle closure according to the invention, which is also synonymously referred to as a grip stopper, now makes it possible, in particular by means of the provided flexible sealing lamellae of the tubular lamellar seal on the peripheral surface of said shaft, to have a higher tolerance range with respect to the inner diameters of the bottle mouths to be closed. Furthermore, the bipartite nature of the bottle closure, that is, the stem attached to the cap on one side and the lamellar seal on the other side, provides greater flexibility in material selection. Thus, the material for the lamellar seal can be selected for optimum sealing on the one hand and the material for the shaft and the associated cap can be selected according to other criteria, such as weight, visual appearance, stability, sprayability, etc. Last but not least, this gives the possibility to improve the visual appearance of a bottle cap.

The bottles to be closed are in particular wine bottles, juice bottles, champagne bottles, spirits bottles, or soft drinks, and non-alcoholic foods.

It can be seen that, if necessary, safeguards to secure the bottle closure, such as a champagne bottle, can be provided. Such a fuse may be a clip lock, a so-called 4-wire fastener, a shrink wrap or similar suitable safeguard.

According to a further embodiment of the present invention, the cap and the shaft can be formed in one piece and / or rotationally symmetrical. In particular, the one-piece is of great advantage, since thus a production, for example by means of injection molding, is made possible in a single step. Only the tubular lamellar seal then still has to be pulled over the projection onto the shaft, where it is then firmly seated on the shaft by a bias.

Preferably, the tubular lamellar seal is applied to the shaft in a spraying process, particularly preferably a two-component injection molding process, so that a subsequent assembly step of the lamellar seal is dispensed with. The lamellar seal is included in particular additionally held by the projection and / or by a circumferential groove and an inner edge which engages in the groove on the shaft.

According to a further embodiment of the invention, the cap may have a lid which is firmly clipped or screwed to the top of the cap. Such a lid in turn may be made of a different material than the cap itself or the shaft. For example, the lid can be made of an even lighter material, so that the weight of the bottle cap can be reduced overall. A further weight reduction can be achieved in that the cap and / or the shaft have a, preferably common, cavity. The lid is preferably substantially disk-shaped or clock-shaped, so that the handle plug is easy to hold in the user's hands during the opening of a bottle and there is no risk of injury.

The cap can be formed in particular cylindrical or dome-shaped according to an embodiment of the bottle closure according to the invention. The cap preferably has a cavity. The cap is preferably flattened at its upper end.

According to a further embodiment variant of the bottle closure according to the invention, the cap and the stem of the bottle closure are injection-molded, preferably together. This allows the simplest possible and cost-effective production. Furthermore, this eliminates the need to connect the cap and shaft. In addition, high stability is achievable.

According to a further advantageous embodiment of the bottle closure according to the invention, the cap and / or the shaft preferably have a cavity, whereby in particular a weight reduction of the bottle closure can be achieved. Furthermore, material costs are saved for the production.

According to a further embodiment of the bottle closure according to the invention, the lamellar seal is made of a first material, preferably a plastic selected from the group consisting of LD-PE (polyethylene), EVA (ethylene vinyl acetate) and PP (polypropylene).

The bottle closure according to the invention is designed according to a further embodiment such that the shaft and the cap are made of a second material, and Although preferably made of a plastic selected from the group consisting of PC (polycarbonate), PS (polystyrene), HD-PE (polyethylene), SAN (styrene-acrylonitrile), PMMA (polymethyl methacrylate), PET (polyethylene terephthalate), ABS (acrylonitrile-butadiene Styrene copolymer) and the like, or a copolyester such as tritan or others.

According to a further embodiment of the bottle closure according to the invention, said first material of the lamellar seal is preferably selected differently from said second material of the stem and the cap. Thus, the first material for the lamellar seal, in particular for optimum sealing, can be selected on the one hand, and the second material for the shaft and the cap associated therewith selected for other criteria, such as weight, visual appearance, stability, sprayability, etc.

In the event that the said second material for the shaft and the cap is a plastic, the Shore D hardness of the plastic is preferably in a range of 50 to 90, in particular 60 to 85, preferably 70 to 85. Thereby a very high stability of both the shaft and the cap can be achieved. The plastic is preferably selected from the group given above for the second material. Optionally, an HD-PE can be used for the shaft and the cap, where "HD" stands for "high density". Such a higher density polyethylene preferably has a density of between 0.94 g per cc and 0.97 g per cc, and consists of weakly branched polymer chains.

In the event that the said second material for the shaft and the cap is a plastic, this is in particular made clear, translucent or colored. In this way, a glass optic can be achieved for the bottle closure according to the invention. If necessary, the plastic used can be dyed.

The plastics used of said first material for the lamellar seal preferably have a lower density than said second material for the shaft and the cap. This can be achieved for example by a highly branched polymer chain in the plastic of the first material. The density of said lamellar sealant should ideally be between 0.915 g per cc and 0.935 g per cc. For example, a low density polyethylene is also referred to as LD-PE, where "LD" stands for "low density". The LD-PE preferably has a Shore D hardness of about 40 to 50. Also for the case that for the lamellar seal the plastic EVA, PP or If something similar is used, the Shore D hardness should preferably be between 40 to 50.

In a preferred embodiment, the tubular lamellar seal is applied or applied to the shaft by a spraying method. The lamellar seal is preferably applied using a multi-component injection molding process. This eliminates a mounting step in which the lamellar seal is mounted on the shaft and the production of the bottle cap is facilitated.
According to a further preferred modification of the invention, the lamellar seal is tensioned by a bias on the shaft. Preferably, the projection and a circumferential groove hold the leaf seal, which is biased by a bias on the shaft. In a further embodiment, the lamellar seal on an inner edge, which fits exactly into the circumferential groove of the shaft. Both alone by the projection of the shaft, as well as alone or in combination with the inner edge of the lamellar seal, which engages in the groove of the shaft, a good seal of the lamellar seal on the shaft is achieved by a firm concern on this. An additional gluing or the like is superfluous, so on the one hand avoided further steps in the production and possible penetration of adhesives and the like in the liquids to be closed in the bottle is avoided. It can be seen that said projection prevents slippage of the lamellar seal on the shaft in its longitudinal direction. This is aided by the fact that the lamellar seal strikes against the projection on the one hand and against the bottom of the cap on the other hand.

According to a further embodiment of the bottle closure according to the invention, the shaft is closed at the end opposite the bottom of the cap. The formed at this closed end of the shaft end surface may be formed flat or curved.

The shaft of the bottle closure according to the invention is preferably designed as a hollow cylinder. It can be seen that its cavity can be connected to the cavity of the cap.

The wall thickness of the shaft, the cap and optionally also the lid of the bottle closure according to the invention is preferably between 0.5 mm and 5 mm, in particular between 0.5 mm and 4.5 mm, more preferably between 1 mm and 4 mm, more preferably between 1.5 mm and 4.5 mm and more preferably between 1.5 mm and 3.5 mm. It can be seen that the wall thickness of the shaft in the region of said projection preferably has a somewhat higher value than the wall thickness of the remaining shaft. In other words, the wall thickness of the shaft in the portion A of the length of the shaft is slightly less than the wall thickness in the region of the bottom of the cap opposite end of the shaft, ie in the region of the shaft starting with the projection.

According to a further embodiment of the bottle closure, the lid is made of a plastic, preferably selected from the group consisting of PC (polycarbonate), PS (polystyrene), PE (polyethylene), PP (polypropylene), SAN (styrene-acrylonitrile), PMMA ( Polymethyl methacrylate), PET (polyethylene terephthalate), ABS (acrylonitrile-butadiene-styrene copolymer), EVA (ethylene-vinyl acetate) and the like or a copolyester such as tritan or others. The lid can be colored arbitrarily, since this part of the bottle cap can not come into contact with the liquid within the bottle to be closed. Since the lid is clipped or screwed into the cap, the lid can also be replaced. This allows, for example, in the production of a large number of uniform bottle caps subsequently flexible design of the lid.

According to a further embodiment of the bottle closure, the tubular lamellar seal has a flange-like sealing ring at its end located at the bottom of the cap. This is preferably at the bottom of the cap. By such a flange-like sealing ring on the lamellar seal an optimal closure of the bottle is achieved. Thus, in particular in the case of a bottle closure placed on a bottle, said flange-like sealing ring can rest on an upper edge of the bottle neck and thus achieve a further seal in addition to the lamellae. The flange-like sealing ring has the further advantage that a noise attenuation is achieved when closing a beverage bottle with the bottle closure according to the invention, since a direct impact of the cap of the bottle closure on the upper edge of the bottle neck is avoidable. Especially when reclosing a bottle by an end user thus damping can be achieved. A hard striking the dimensionally stable plastic of the cap at the mouth of the bottle, however, could be perceived as "cheap". Furthermore, by the flange-like sealing ring damping during insertion of the bottle cap in causing a bottleneck from the point of view that any damage to the top of the neck of the bottle is avoided.

The portion A of the length of the shaft over which the lamellar seal of a bottle closure according to the invention extends is preferably 45 to 100%, more preferably 55 to 85% and most preferably 65 to 75%. Thus, the portion A of the length of the shaft over which the lamellar seal of a bottle closure according to the invention extends, for example, in about 2/3 of the total length of the shaft or completely cover the shaft.

The lamellar seal of a bottle closure according to the invention preferably has two to seven, more preferably three to five, for example four, projecting annular, flexible, outwardly formed and concentrically arranged sealing lamellae. The sealing lamellae in particular all have the same outer diameter. According to an advantageous further development, the sealing lamella arranged closest to the projection has a smaller outer diameter in comparison to the remaining sealing lamellae of the lamellar seal. It can be seen, however, that in any case the outer diameter of the sealing lamellae is greater than the outer diameter of the shaft in the region of the projection. In other words, the projection of the shank must not extend beyond the maximum circumference of the sealing lamellae.

According to a further embodiment, the tubular lamellar seal is open on both sides, or closed at the opposite end of the bottom of the cap. It is advantageous on a lamellar seal closed on one side that only the lamellar seal comes into contact with the liquid or the food. This provides additional protection against microbiological contaminants between the lamellar seal and the stem, which is important for example for soft drinks or food.

According to a further embodiment of the bottle closure, the shank tapers conically at the end opposite the bottom of the cap. This taper preferably starts from the area of the projection. By such a taper, on the one hand, during the production of the bottle closure, a simple sliding of the tubular lamellar seal onto the shaft and, on the other hand, a simple introduction of the bottle stopper into a bottle to be sealed is made possible.

According to a further embodiment, the tubular lamellar seal which is closed at the end opposite the bottom of the cap encloses closely the stem, which tapers conically at the end opposite the bottom of the cap. The lamellar seal does not slip when the bottle cap is inserted into the bottle to be closed. Since the lamellar seal has a lower Shore-D hardness and density than the shaft, the lamellar seal is softer, thereby facilitating the insertion of the bottle cap into the neck of the bottle.

It can be seen that the bottle closure according to the invention is particularly suitable for closing such beverage bottles containing liquids or foods with little or no carbonic acid. In particular, the bottle closure can be used without securing agent. Furthermore, the bottle closure according to the invention makes it possible to reclosure once opened beverage bottles. Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of embodiments with reference to the drawings. Show it:

FIG. 1 shows a bottle closure 1 according to the invention in a side view. Such a bottle closure is for example for closing wine bottles, champagne bottles, spirits bottles, soft drinks or non-alcoholic foods suitable. The bottle cap 1, so a handle plug, for closing of such beverage bottles has for this purpose a cap 2 with a shaft 3, which extends centrally from the bottom 10 of the cap 2. The cap 2 is here dome-shaped and the shaft 3 has a substantially cylindrical shape. The cap 2 and the shaft 3 form a common drawing not shown cavity. At the bottom 10 of the cap 2 opposite end of the shaft 3 is a conclusion 6, which is just executed here. In the upper part of the cap 2, a lid 8 is clipped. On the shaft 3, a tubular lamellar seal 4 is stretched. This lamellar seal 4 extends over the portion A of the length of the shaft 3. The portion A is bounded on its upper side by the bottom 10 of the cap 2 and bounded on the opposite lower side by the projection 7 on the shaft 3. It can be seen that said projection 7 prevents the slat seal 4 from slipping on the shaft 3 in its longitudinal direction. This is achieved by the lamellar seal 4 abuts the projection 7 on the one hand and on the bottom 10 of the cap 2 on the other. The lamellar seal 4 has a plurality of projecting annular, flexible, outwardly formed and concentrically arranged sealing lamellae 5. It is in this embodiment, four sealing lamellae 5, wherein the projection 7 immediately adjacent sealing lamella 5 has a slightly smaller outer diameter than the other sealing lamellae 5. The projection 7 located at the end of the shaft 3 opposite the bottom 10 of the cap 2 is essentially an extension of the diameter of the cylindrical shaft 3.

In FIG. 2 a bottle closure 1 according to the invention is shown with a cap 2 and a lid 8 clipped into the cap 2, the bottle closure 1 closing a beverage bottle 11 by inserting the bottle closure 1 into the bottle neck 12.

FIG. 3 shows the items of a bottle closure 1 according to the invention for closing of beverage bottles, especially wine bottles, champagne bottles or spirits bottles, comprising a cap 2 with a cylindrical shaft 3, which extends centrally from the bottom 10 of the cap 2. It can be seen that both the cap 2 and the shaft 3 here essentially have a cylindrical basic shape. Both are connected to each other via a common cavity. The shaft 3 has the projection 7. The lid 8 has a watch-glass shape in this embodiment. Furthermore, the lamellar seal 4 is shown separately, which has a plurality of projecting annular, flexible, outwardly formed and concentrically arranged sealing lamellae 5. At the top End of the lamellar seal 4, a flange-like sealing ring 9 is formed. This sealing ring 9 is intended to be brought into abutment after pushing the tubular plate seal 4 on the shaft 3 of the bottle closure 1 at the bottom of the bottom 10 of the cap 2.

In FIG. 4 an inventive bottle closure 1 is shown in a partial sectional view, wherein the sectional view in the right half of the illustration is shown starting from the central axis. The bottle cap 1 has a cap 2 with a cylindrical shaft 3, which extends centrally from the bottom 10 of the cap 2. The shaft 3 has at the opposite end of the bottom 10 of the cap 2 a flat termination 6. The cap 2 and the shaft 3 are integrally formed and form a common cavity. This unit can be made, for example, by injection molding from a single material, in particular plastic such as polycarbonate (PC), polystyrene (PS), HD-PE (polyethylene), SAN (styrene-acrylonitrile), PMMA (polymethyl methacrylate), PET (polyethylene terephthalate), ABS (acrylonitrile-butadiene-styrene copolymer) or the like, or a copolyester such as Tritan or others. The wall thickness of the cap 2, the shaft 3 and the closure 6 is here substantially identical and may be, for example, about 1.5 to 4 mm. In the upper region of the cap 2, a lid 8 is inserted, for example clipped, which has a disc shape here.

Furthermore, in Fig. 4 the lamellar seal 4 can be seen, which extends over the portion A of the length of the shaft 3. The portion A of the shaft 3 is limited at its upper end by the bottom 10 of the lid 2 and at its lower end by the projection 7 of the shaft 3. The lamellar seal 4 has at its upper end a flange-like sealing ring 9, which rests against the underside of the bottom 10 of the cap 2. The lamellar seal 4 here has, for example, four annular, flexible, outwardly formed and concentrically arranged sealing lamellae 5. The projection 7 immediately adjacent sealing lamella 5 has a slightly smaller outer diameter than the other three sealing lamellae 5. The lamellar seal 4 is, for example, a plastic, selected from the group consisting of LD-PE ("low density" polyethylene), EVA (ethylene vinyl acetate) and PP (polypropylene) manufactured. The projection 7 located on the end of the shaft 3 opposite the bottom 10 of the cap 2 is essentially a section-wise widening of the diameter of the cylindrical shaft 3. This projection 7 prevents the slat seal 4 from slipping on the shaft 3. This is achieved. in that the lamellar seal 4 strikes against the projection 7 on the one hand and against the bottom 10 of the cap 2 on the other hand.

In FIG. 5 is a section of a further embodiment of the bottle closure 1 to recognize, wherein the lamellar seal 4 separated from the bottle closure 1 is shown. The lamellar seal is closed at the opposite side of the bottom of the cap and feels the conical converging shape of the shaft 3 below the projection 7. If the plate seal 4 is mounted on the shaft 3, it encloses its end closely and is held by the own bias and by the circumferential groove 13 and the projection 7 on the shaft 3. The lamellar seal 4 rests with the flange-like sealing ring 9 on the bottom of the cap 10 and surrounds the shaft 3 completely. The portion A of the shaft 3 is limited at its upper end by the bottom 10 of the lid 2 and at its lower end by the end 6 of the shaft 3. As can be seen, an inner edge 14 of the lamellar seal completely fills the groove 13. In a preferred embodiment, the lamellar seal 4 is sprayed onto the shaft 3 with a two-component injection method, whereby the step of winding up the lamellar seal 4 over the shaft 3 is saved and a particularly secure hold is obtained.

The invention is not limited to any of the above-described embodiments, but can be modified in many ways.

All of the claims, description and drawings resulting features and advantages, including design details, spatial arrangements and method steps may be essential to the invention, both in itself and in various combinations.
