Definitions

  • the present invention relates to a glass container comprising a neck, an opening in the neck and a cover member closing off the opening, which cover member comprises an inward side and an outward side.
  • Closing means for bottles are known in the prior art. Glass bottles are generally sealed with a cork, plastic cap or a screw cap. Glass bottles containing beer or other carbonated beverages are generally sealed with a metal closure that is crimped around a groove that is a feature of the outer neck of the bottle.
  • the commonplace form of this closure device is the crown cork, which is a pressed steel disk formed with a skirt of 21 tines.
  • Carbonated beverages may also be contained in plastic bottles, generally made from polypropylene (PP), polyethylene terapthalate (PET) or polyethylene naphtalate (PEN).
  • PP polypropylene
  • PET polyethylene terapthalate
  • PEN polyethylene naphtalate
  • the closure devices of these plastic bottles are usually screw caps, which are screwed on a threaded neck of the bottle.
  • the glass container according to the present invention is characterised in that the cover member comprises on its inward side a flexible closing element that is expandable in the neck connected with an operating means on the outward side of the cover member, the flexible closing element being operable by the operating means between a first position in which the flexible closing element is radially expanded towards the neck, and a second position in which the flexible closing element is spaced away from the neck.
  • the flexible closing element may be of generally conical shape and in its first position sealingly engages the wall of the bottle neck and may be placed in a second position where the sealing element is spaced away from the wall of the neck.
  • the glass container according to claim 1 comprises a resilient clamping means, the flexible closing element being compressible by the resilient clamping means. By compression of the flexible element, this element expands in the neck of the bottle and seals off the opening.
  • the advantage of this embodiment of the closure device is that high pressures in glass bottles, such as beer bottles, can be withstood, without loss of carbon dioxide from within the bottle.
  • the resilient clamping means and/or the flexible sealing element is a bi-stable element.
  • a bi-stable element as resilient clamping means produces a rapid and distinct opening event, after an inversion point in passing from the expanded to the contracted state has been passed.
  • the cover member comprises of a central axis, a stopper member engaging a rim of the neck the flexible closing element and the resilient clamping means being placed on the axis, the clamping means in its first position compressing the flexible closing element against the stopper member, and being displaceable away from the stopper member by pressing down on the central axis.
  • the stopper member that engages the rim of the neck seals the top of the glass bottle, so that no dirt is able to pass the closure mechanism that is placed under the stopper member inside the neck of the closed bottle.
  • the central shaft comprises a central stem having on the outward side of the stopper member a wide top end and on the inward side a broadened end part, the stopper member, the flexible closing element and the resilient clamping means being with a central opening placed around the stem between the top end and the broadened end part.
  • a construction provides a relatively simple and integrated closure device, which can be handled without separate parts that have to be disassembled to open the closure. The user can open the closure by pressing down on the top end. The pressure that is applied on the top end moves the axis into the glass container so that space is created for the resilient clamping means to snap into an expanded position in which the flexible element can expand along the axis resulting in a reduced diameter thereof. A clearance will thus appear between the flexible element and the neck of the bottle.
  • the resilient clamping means comprises a conical form with a substantially circular centre part, where a number of resilient fingers are attached, which provides an efficient bi-stable structure that can be placed in a first closed position and in a second opened position.
  • the flexible closing element comprises a cylindrical part and a conical end, which conical end lies against an internal surface of the resilient clamping means. The transfer of the pressure is very advantageous over the conical surface, because horizontal as well as vertical forces are transferred.
  • the flexible closing element comprises an elastic material. Once the material has been deformed, it will tend to revert to its original shape, so that no plastic deformation of the elastic material will occur. Being able to withstand pressures to a maximum of 6 - 7 atmospheres, the bottle is preferably to be used for carbonated beverages, especially beer. Pressures that high occur while the beer is being pasteurised. During normal serving temperature the pressure will be around 1 - 1.5 atmospheres.
  • FIG. 1 shows an exploded view of the closure device according to the present invention
  • Fig. 2 shows a sideview of the closure device and the glass bottle according to the present invention
  • Figure 1 shows an exploded view of the closure device 1 according to the present invention.
  • the closure device 1 comprises a stopper disk 3, a flexible closing element 2 and a conical bi-stable element 8.
  • the first side of the closure device 1 comprises a broadened top end, forming a push button 6 for applying a pressure on the axis 5.
  • the substantially flat stopper member 3 On the first side of the axis 5 the substantially flat stopper member 3 has been placed against the push button 6, in order to seal and cover the opening 7 of the neck of the bottle 4 and to prevent the closure device 1 from entering into the bottle 4.
  • a flexible closing element in form of a piece of elastic material 8, has been placed against the stopper member 3.
  • the second side of the axis 5 shows a bi-stable element 2 in form of an umbrella- shaped metal plate or plastic plate. This plate has a central part 12, which central part comprises a hole, through which hole the axis 5 runs.
  • the clamping means 2 By applying a pressure F on the push button 6 in a longitudinal direction of the axis 5, the clamping means 2 is moved from its first bi-stable state to its second bi-stable state in which the pressure clamping means 2 exerts on the flexible closing element 8 decreases, so that the flexible element 8 expands in the longitudinal direction of the axis 5 and contracts in the radial direction, so that a clearance (not shown) will appear between the flexible element 8 and the neck of the bottle.
  • a clearance (not shown) will appear between the flexible element 8 and the neck of the bottle.

Abstract

La présente invention porte sur un récipient (4) en verre comprenant un goulot (10), une ouverture (7) située dans le goulot (10) et un bouchon (1) destiné à refermer l'ouverture (7) et comprenant un coté intérieur et un côté extérieur. Ce bouchon (1) est caractérisé par la présence sur son côté intérieur d'un élément de fermeture souple (8), extensible dans le goulot et relié à un élément fonctionnel (6) à l'extérieur ou sur le côté extérieur du bouchon, l'élément de fermeture souple pouvant être actionnée par ledit élément (6), entre un première position dans laquelle l'élément de fermeture souple (8) est radialement étendu en direction du goulot (10), et une seconde position dans laquelle ledit élément de fermeture (8) est contracté vers l'intérieur, loin du goulot. En utilisant le dispositif de fermeture (8) de l'invention, aucun outil spécial n'est nécessaire pour ouvrir le récipient en verre. On utilise de préférence ce dispositif de fermeture conjointement à des boissons gazeuses.
