Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 is a beverage bottle in a side view, and

[0024] FIG. 2 is the beverage bottle according to FIG. 1 in longitudinal section. Identical parts are provided in both figures with the same reference numbers.

DETAILED DESCRIPTION

[0025] The beverage bottle 1 according to FIGS. 1 and 2 comprises a bottle body 2, to which a bottleneck 4 is connected. The bottleneck 4 connects into a mouthpiece 6, which is provided with a pouring opening 8 for the liquid stored in the beverage bottle 1. In the execution example, the beverage bottle 1 is designed in the shape of a wine bottle; Alternatively, the shape as a sparkling wine, mineral water, water, beer, liquor, vodka or fruit juice bottle or as a container for other liquids, in a format readily to sale, are possible.

[0026] The beverage bottle 1 is designed as a thermally insulating bottle, in which the liquid there-in is kept in an elevated or lowered temperature over an extended period of time. The beverage bottle 1 can therefore keep the liquid therein warm or cold. For this purpose, the bottle body 2 is double-walled and comprises an outer container wall 10, within which an inner container wall 14 is arranged to form a gap 12. The inner container wall 14 forms the actual vessel in which the respective liquid is held, and which is surrounded by the outer container which forms the outer shell 10 for protection purposes.

[0027] The beverage bottle 1 is especially designed to the extent for a possible use as a reusable and returnable bottle and/or for use in machine filling and on an industrial scale. In view of the required increased mechanical stability of the space 12in contrast, for example, to a thermos or vacuum bottleit is not provided with a vacuum, but with a comparatively poor thermal conductivity material, in the execution example it is filled with air. Alternatively, the gap 12 can also be filled with an inert gas which has a low thermal insulation coefficient, such as Xenon, or it can be filled with a foam, for example polyurethane foam. In order to ensure on the one hand, a high insulating effect for the liquid and on the other hand for the intended use, the necessary high mechanical stability and strength, the gap 12 is extended and extends beyond the bottleneck 4 up to the mouthpiece 6. The mouthpiece 6 is specifically provided as a point of contact for mechanical forces and designed accordingly.

[0028] To achieve the design goals, the double-walled configuration of the bottle body 2 extends up to and including the neck 4, so that the insulating gap 12 with the exception of the pouring piece 8 almost completely surrounds the interior of the beverage bottle 1, and to ensure increased mechanical stability, both the outer container wall 10 and the inner container wall 14 are each connected in one piece with the mouth piece 6 or bonded to the mouth piece 6.

[0029] In particular, with the comparatively large internal volume of the beverage bottle 1, transverse forces of considerable extent could occur as a result of the weight of the liquid therein, which could cause a risk of breakage at the connecting part of the inner container wall 14 with the mouth piece 6. To counteract this, a support connection piece 16 between the inner and outer container wall 10, 14 is provided at the bottom region of the beverage bottle 1, via which such forces can be transferred to the bottom of the bottle. In the execution example, a connection piece 18 is provided for forming a support structure, via which the inner container wall 14 is supported on the outer container wall 10. Alternatively or additionally, it is also possible to provide multiple support connections, and/or the floor of the outer container wall 10 can be curved or curved inwards in the central area, i.e., toward the inner container wall 14, and to be connected to it or connected in part with the bottom. Through these types of connection, the forces acting on the bottle parts when the containers are filled are transferred to the bottle structure.

[0030] In principle can the vessel be formed by the inner container wall 14 and the outer container wall 10 and could consist of a material which is preferably selected for industrial processing and mass production, for example plastics. In the execution example, is glass, in particular borosilicate glass, chosen as the base material for the inner and outer container walls 10, 14.

[0031] With regard to the preferred use of the beverage bottle 1 as a returnable and reusable bottle, the closure system for the vessel opening is designed for re-filling and re-closability. For this purpose, the mouth piece 6 at the pouring opening 8 is designed for mounting a reusable closure and is in particular designed such, that it can accommodate a cork, bottle caps or other reusable closures.

[0032] The inner vessel body is formed by the inner vessel wall 14 and is arranged at the outer vessel body formed by the outer vessel wall 10 in such a way, that a gas-filled space 12 is formed between the inner vessel body and the outer vessel body. In order to allow a reliable production while avoiding the risk of breakage due to thermal pressure fluctuations, the outer container wall 10 is provided with a vent opening 20. This hole is sealed with a plug 21 or otherwise, for example by means of a seal, and serves as a pressure equalization opening, which allows, in particular during assembly, a gas exchange for pressure equalization between the gap 12 of the two vessel bodies and the outer space. This pressure equalization hole is preferably closed after completion of the manufacturing process by a plug, glass material or adhesive to prevent moisture or contaminants from entering into the gap 12, which reduce the insulating ability. This pressure equalization opening is particularly important in the preferred intended use of glass as a base material to avoid stresses during manufacture and in particular during the fusion of the two vessel bodies.

[0033] In the execution example, the outer container wall 10 is coloured and frosted in a partial area. As a result, some light protection for the liquid can be provided to some extent, which improves the durability of the liquids especially for photosensitive liquids such as wine or the like. Furthermore, such a configuration is also particularly suitable for decorative purposes or for attaching information, for example in the form of labels, stickers or the like.

[0034] In FIG. 2, shows an alternative example of the beverage bottle 1, the bottle body 2 is provided with an outer circumferential support 22 as reinforcement. This increases the mechanical stability of the vessel.

[0035] Such a glass bottle 1, 1 is preferably produced by first providing the outer and the inner vessel body, wherein at least one of these vessel bodies has a wall with a pressure equalization hole. The inner vessel body is then placed in the outer vessel body and connected thereto. This is preferably done by fusing or welding together the inner and outer vessel bodies in at least one area, preferably in an upper edge area, of the two vessel bodies. This creates the air-filled gap 12 between the two vessel bodies. While the vessel bodies are connected to each other, the vent opening 20 allows a gas exchange between the gap 12 and the outside space, so that in the space 12 no excess or negative pressure can arise. This is necessary because, due to the high temperatures of several hundred degrees Celsius during melting, an overpressure would occur in the gap. After the vessel bodies have been joined together, the gap 12 can optionally be flushed through the vent hole 20 with a gas, for example air or an inert gas such as nitrogen or xenon, and therefore dried. Subsequently, the pressure equalization hole is closed by the plug, glass material, silicone or adhesive, to prevent water and contaminants enter into the space between the containers and to stop air or gas to escape.
