Definitions

• the invention relates to a closure element for bottles according to the preamble of claim 1.
• Closure elements of the type mentioned here are known. They are used in particular in bottles with high-quality contents, especially those made of glass. A sealing element is provided to ensure that the contents of the bottles are sealed. After closure at the manufacturer, closure elements of the type mentioned here are generally secured, for example by a plastic or aluminum cap that holds the closure element on the bottle. After the first opening, ie also the removal of the cap, the closure element is held in place by the friction prevailing between the sealing element and the bottle. If the pressure inside the bottle rises, it can therefore happen that the closure element is pushed out of the mouth area of the bottle so that it loses its hold and possibly falls off completely. The object of the invention is therefore to provide a closure element for bottles which does not have this disadvantage.
• a closure element which shows the features mentioned in claim 1. It has a stopper which engages in the mouth of the beverage bottle and a head with an outer diameter which is larger than that of the stopper.
• a sealing element which is arranged in the transition area between the stopper and the head, has a first sealing area which rests on the stopper.
• the interior of the Drinking bottle is closed by at least one outward-pointing sealing bead, which is provided in the first sealing area.
• the closure element is characterized in that at least one outwardly projecting projection is provided on the side of the first sealing region facing away from the head, preferably an annular bead which has at least one recess made in the peripheral surface of the bead.
• the invention is explained in more detail below with reference to the drawing.
• the single figure shows a schematic diagram of a closure element in side view with a sealing element in longitudinal section.
• the illustrated closure element 1 has a stopper 3 which can be inserted into the mouth of a bottle.
• a head 5 adjoins the stopper, the outer diameter of which is larger than that of the
• Stopper 3 For example, it can be provided that the outer The outer diameter of the head 5 essentially corresponds to that of the bottle in the mouth area, so that the bottle virtually passes into the closure element.
• Plug 3 and head 5 are preferably formed in one piece.
• a sealing element 7 is provided, which has at least one first sealing area 9 resting on the plug 3.
• a second sealing region 11 adjoining it is provided, which bears against the head 5 from below.
• a sealing bead 13 is provided here, which seals the interior of a bottle from the surroundings. It is possible to provide several such ridges on top of each other, that is, at a distance from one another.
• an annular bead 15 is provided here, which has at least one recess in its circumferential surface, which does not seal the interior of the bottle from the sealing bead 13, that is to say represents a passage. Pressure acting in the interior of the bottle can therefore continue to act on the sealing bead 13.
• bead 15 it is also possible to provide at least one projection, preferably a number of projections, which are arranged at a distance from one another on an imaginary circumferential line and do not seal the interior of the bottle from the sealing bead 13 in a pressure-tight manner.
• An inner bead 17 is provided on the side of the first sealing region 9 facing the stopper 3, which is in the lower region of the sealing bead 13 is provided, but has a smaller extent and a smaller height when viewed in the direction of the central axis 19 of the closure element 1.
• the inner bead 17 serves as a support for the sealing bead 13 and as a support for the sealing element 7 on the stopper 3.
• an inner bead can also be provided in the region of the bead 15 or the at least one projection provided here.
• the dimension and number of the at least one inner bead 17 can be adapted to different applications.
• annular bead 21 running concentrically to the central axis 19 is provided on the underside of the second sealing region 11 facing away from the head 5.
• annular beads 21 and 23 arranged concentrically to one another are shown. These can serve as an additional seal, but also to resiliently absorb an impact on the closure element 1 while it is placed on a bottle and is supported with the annular beads 21, 23 on the wall area of the bottle surrounding the mouth.
• closure element 1 The following should be noted regarding the function of the closure element 1:
• the closure element 1 is placed on a bottle, so that the stopper 3 engages in the mouth thereof and the head 5 is supported on the wall area of the bottle that surrounds the mouth.
• the sealing element 7 serves to seal off the interior of the bottle, at least a first sealing area 9 in the area of the stopper 3 ensuring the closure.
• a second seal tion area 11 are provided.
• the sealing element 7 is preferably formed in one piece, so that the first sealing area 9 merges into the second sealing area 11.
• the first sealing area 9 is essentially cylindrical or slightly conical and is concentric with the central axis 19.
• the second sealing area 11 lies in a plane on which the central axis 19 is perpendicular.
• the sealing bead 13 ensures the tight closure of the interior of the bottle. As a rule, it also provides sufficient holding forces to hold the closure element 1 on a bottle. Additional holding forces are built up by the at least one projection, as seen from the head 5, below the sealing bead 13 or by the bead 15. It is essential that there is no seal of the interior of the bottle here, so that a pressure that builds up here acts up to the sealing bead 13.
• the stopper 3 is pushed out of the mouth of the stopper until the overpressure can escape past the sealing bead 13.
• the closure element 1 still finds sufficient hold in the mouth of a bottle, because at least one projection, preferably the bead 15, is provided below the sealing bead 13. Since this is provided with at least one recess, the internal pressure in the bottle can escape here, so that there is no further axial displacement of the closure element 1 out of the bottle.
• the closure element While in the originally closed state, the head 5 of the closure element 1 rests practically entirely on the wall of a bottle surrounding the mouth, namely at a distance predetermined by the second sealing element 11, the closure element is in a position after removal of an increased internal pressure in the interior which increases the distance between the head 5 and the bottle. This alone shows a consumer that the closure element has been displaced in the bottle due to internal pressure. In the case of non-gassing content, this shift could be used as an indication that the content has spoiled and is fermenting.
• the closure element 1 is preferably made entirely of glass, so that it does not affect the taste of the contents in the bottle. It would be enough to simply make the stopper out of glass, at least the areas that come into contact with the contents of the bottle.
• the closure element 1 can also consist of metal, ceramic and a plastic which does not impair the taste of the contents of the bottle. Accordingly, for. the sealing element 7 selected a plastic which on the one hand is sufficiently elastic to ensure that the interior of the bottle is sealed, but on the other hand provides the closure element 1 with sufficient hold on the bottle and likewise does not impair the taste of the contents.
• the closure element 1 it is possible to produce the closure element 1 from glass, metal or ceramic and to provide it with a plastic coating which realizes the sealing element 7 and has an outer contour, as is provided for the sealing element 7.
• the functional principle of the closure element 1 makes it clear that the sealing element 7 has at least one sealing bead 13 which seals the interior of a bottle, and also a holding area which holds the closure element 1 securely on a bottle even after it has been displaced in the direction of the central axis 19.
• at least one projection is provided below the sealing bead 13, ie on the side facing away from the head 5, which can hold the closure element 1 in the mouth region of a bottle.
• a plurality of projections but in particular a circumferential bead 15 with at least one recess is provided, which also offers the closure element 1 a secure hold in the mouth of a bottle when the closure element 1 has been displaced somewhat in the direction of the central axis 19.
