Definitions

  • the invention relates to an adaptable glass stopper for sealing bottles with a circular or non-circular shape of the mouth of the bottle, comprising a head part of the stopper, a following conical part for inserting into the mouth of the bottle and an adaptable sealing element.
  • the fitting area of the head part of the stopper has a ground plan which is at least identical or bigger compared to the outer dimension of the mouth of the bottle, whereas the upper part of the head part of the stopper may be of any shape, facilitating to distinguish the producers of beverage bottles.
  • the lower conical part contains a fixing groove for the adaptable, highly efficient, sealing element, which guarantees the sealing of differences in the parameters of the mouth of the bottle of up to 1.1 mm, characterised by the fact that it has at least two or more sealing rims in the mouth of the bottle.
  • the invention relates to an adaptable glass stopper for sealing bottles, namely bottles for spirits, distilled liquors, optionally wine, having a circular or non-circular shape of the mouth of the bottle.
  • the adaptable glass stopper comprises a head part, the basic outer dimension of which is bigger than or at least identical to the outer dimension of the mouth of the bottle, further a conical part of the bottle, following firmly the head part and containing a fixing groove with a highly adaptable sealing element, for inserting into the mouth of the bottle.
  • This sealing element is provided with at least two sealing rims with the function of sealing the bottle against leaking of the liquid and against spontaneous release of the stopper when used repeatedly.
  • Glass stoppers are known from the European patent 1 456 092 .
  • Several types of sealing methods are suggested for the glass stopper according to this patent, such as a frontal sealing between the neck and the head part of the stopper, and further a combination of the frontal and cylindrical sealing in the mouth of the bottle.
  • a disadvantage of therein described methods is the requirement for use of special bottles with a guaranteed precision of the mouth of the bottle which requires a circular cross-section of the mouth of the bottle with a very small dimension tolerance. It means that for a reliable sealing function, the function dimensions, including the tolerance of the diameter of the mouth of the bottle, the stopper entering the mouth of the bottle, and the sealing ring, must be fulfilled.
  • Another disadvantage is that there is only one sealing bead in the mouth of the bottle to perform the sealing and the resistance against spontaneous release of the stopper. In case this bead is damaged, the repeated sealing is very problematic.
  • Another closure element is known from the European patent 1 755 973 .
  • a combined sealing ring is used.
  • Another bead is added on the sealing ring in the mouth of the bottle in order to prevent the possible moving of the stopper from the bottle by increasing the frictional power.
  • An apparent disadvantage of this closing element is, similarly as in case of the European patent 1 456 092 , that it requires the use of special bottles with a guaranteed precision of the mouth of the bottle which requires a circular cross-section of the mouth of the bottle with a very small dimension tolerance.
  • Another disadvantage of this principle is that according to this method the sealing ring is not permanently fixed on the glass stopper. There is a risk of a possible damaging of the sealing ring and the loss of its functionality due to the fact that it is not provided with a homing part for correct first inserting of the stopper into the mouth of the bottle.
  • the aim of this invention is to eliminate the above mentioned disadvantages of stoppers.
  • the subject-matter of the invention is an adaptable glass stopper for sealing bottles, namely bottles for spirits, distilled liquors, optionally wine, having a circular or non-circular shape of the mouth of the bottle.
  • the adaptable glass stopper comprises a head part, the basic outer dimension of which is bigger than or at least identical to the outer dimension of the mouth of the bottle, further a conical part of the bottle, following firmly the head part and containing a fixing groove with a highly adaptable sealing element, stretching into the mouth of the bottle.
  • This sealing element is provided with at least two sealing rims with the function of sealing the bottle against leaking of the liquid and against spontaneous release of the stopper when used repeatedly.
  • the sealing method is based on the adaptable adaptation of the stopper itself, together with a new type of adaptable efficient sealing element which is capable of sealing a circular or non-circular shape of the mouth of the bottle, in differences in the sealed parameters of up to 1.1 mm.
  • the main sealing effect of the adaptable sealing element is in the mouth of the bottle, under the forefront of the neck.
  • This adaptable sealing element from an elastic material is characterised by the fact that the principle of the efficient sealing is based on a principle of at least two- or more-rim sealing in the mouth of the bottle with a homing part on the sealing element.
  • the main sealed place in the mouth of the bottle is sealed by at least two or more sealing rims.
  • the increase in resistance against spontaneous release of the stopper from the mouth of the bottle has been unexpectedly achieved, as depicted in Table 1. It is evident from the measured values that the new multi-rim system has up to a threefold resistance against inner pressure compared to that of the original system. Another important advantage is that the multi-rim system is suitable for repeated sealing of the mouth of the bottle.
  • Table 1 A comparison of the resistance against inner pressure in the bottle between the original solution with one sealing bead and the new multi-rim system Value of the maximum sealable inner pressure inside the bottle [MPa] Value of the maximum sealable inner pressure inside the bottle [MPa] Method of fixation of the stopper in the mouth of the bottle Without a fixing element With the fixing element
  • the original solution with one sealing bead 0,035 0,25 New solution - multi-rim sealing element 0,13 0,35
  • the sealing element comprises a homing part which follows the rim system in the mouth of the bottle and which reliably ensures the correct coaxial and uniform insertion of the stopper into the mouth of the bottle, which in turn ensures an even distribution of the stress and the sealing effects on individual rims of the sealing element.
  • the adaptable sealing element is characterised in that the overall height of the sealing element in the axial direction of the part of the stopper is higher than 5.5 mm.
  • a preferred embodiment of the invention features a sealing element with four sealing rims.
  • Another preferred embodiment is characterised by the fact that in case of a multi-rim system, the edges of individual sealing rims may be of a different outer parameter. From the point of view of reliability of the sealing, it is namely convenient for a better adaptation of individual rims to the inner dimension of the mouth of the bottle and to possible shape defects in the mouth of the bottle when inserting the stopper into the mouth of the bottle.
  • Another preferred embodiment of the invention is characterised by the fact that the adaptable element enables to use the principle for sealing non-circular shapes, such as elliptic openings, or even openings formed by a polygon shape with rounded corners.
  • the head part the outer dimension of which is equal to or bigger than the outer dimension of the mouth of the bottle, may be of any shape. It thus enables creative design solutions of bottle and stopper shapes.
  • further fixing elements may be used for transport securing of the stopper, for example thermo capsules, coating or wire bandages etc.
  • the invention is oriented at a glass stopper for closing distilled liquor bottles, optionally this principle may be used for other liquids, for which the materials of the bottle, stopper and sealing element would be chemically inert.
  • the principle of the adaptable glass stopper in this invention provides in the above mentioned sense the required functional safety and repeatability of the sealing effect both in beverage bottles, namely for spirits, and in bottles intended for other liquids, or alternatively for powdery materials.
  • the principle of the adaptable stopper in this invention is in the above mentioned sense applicable to other non-glass materials of the stopper and the bottle.
  • Fig. 1 shows the glass stopper (1) comprising the head part (6) and the conical part (7) and especially the position of the adaptable sealing element (2) with two sealing rims (9) in its unloaded, non-deformed position, in order to enlighten the possibility of sealing reliably both circular and non-circular shapes of the mouth of the bottle in the difference of sealed dimensions (Zmax - Zmin) of up to 1.1 mm.
  • the adaptable sealing element (2) is fixed by moulding into the fixing groove (8) in the conical part (7) of the glass stopper (1). This secures the sealing element (2) against axial movement. Since this sealing element is moulded into the fixing groove (8), a sufficient sealing effect is guaranteed on the side of the glass stopper.
  • the outer dimension of the edge of sealing rims (9) in each direction of the cross-section of the neck of the bottle is bigger than the opening of the bottle in the corresponding direction.
  • the preferred four-rim solution is shown on Fig. 2 .
  • the outer dimensions of the edge of individual rims (9) may be identical, related to the symmetry axis of the glass stopper. From the point of view of the inserting of the glass stopper into the mouth of the bottle (3), the sealing effect and the even loading of individual rims, it is preferable, if the outer dimension of the edges of the sealing rims (9) decrease towards the homing part (11) of the sealing element (2), as depicted in this figure.
  • An undisputable advantage is that the multi-rim system is suitable for repeated sealing of the mouth of the bottle. In some cases it may be possible that the outer dimensions of edges of individual rims (9) will increase towards the homing part (11).
  • Fig. 3 shows the function of the homing part (11) when the stopper (1) is being inserted into the mouth of the bottle.
  • the homing part (11) guarantees an improved coaxiality, with the subsequent even loading of sealing rims (9), when inserting the glass stopper into the mouth of the bottle (3).
  • the sealing effect as such in case of the stopper (1) inserted into the mouth of the bottle (3) is depicted on Fig. 4 .
  • the flexible deformation of the sealing element (2) between the supporting place (10) and the main sealed place (5) guarantees an even contact of all rims (9) on the sealed area.
  • Another preferred embodiment of the invention and an undisputable advantage of the adaptable sealing element (2) is that the advantages of this principle of sealing may be used in bottles with non-circular shape of the neck, as suggested on Fig. 5 . It may be assumed that some non-circular shapes may be advantageous for the subsequent pouring of the liquid out of the bottle.
  • Another preferred embodiment of the invention is that it enables the use of various creative shapes of the head part of the stopper (6), as for example suggested on Fig. 7 . This is convenient for creative design solution of shapes of the bottle and the stopper.
  • Adaptable glass stoppers for sealing bottles with a circular or non-circular shape may be used for beverage bottles, for example for distilled liquors, wine etc.
