The larger the herrschend® in the Piasehe pressure, and is particularly for bottles with carbonated beverages _o piping bad Bichtungseigenschaften "in the bottle closures of known type are partially-estaltung Q to inappropriate and bad on" construction of Flasohenverschlusses, in particular of the cross in the bottle Plug "back", when the plug is pressed into the bottle neck, it does not lie evenly and tightly against its inner surface. Another part of the previous parts of the kitchen is due to the use of unsuitable plastic materials .on the elastic properties. previously had to be used irerMltnissaässig- soft © Kunststoffe _"9 although not sufficiently impermeable to pressurized-standing gas _s © particular Kohlendioxydl are ₀

It has already been proposed "to improve the sealing properties of such bottle seals" to provide a "thickened ring-shaped edge part" which lies on the mouth of the bottle and is followed by a thinner wall section of the seed jacket and the plug part »But even with this, the desired sealing properties could not be fully achieved»

On the other hand, the task of the fire is to design the socket-shaped plug wall in such a bottle neck so that it can adapt to any shape of the inside surface of the bottle and thereby results in a sufficiently firm support _{9 so} that even minor unevenness in the inside of the mouth? surface of the bottle should be completely sealed «, the possibility should be created at the same time to make the bottle cap from» relatively hard plastic, which was previously considered unsuitable for such purposes », which due to its material density is significantly more impermeable to gases than the ones previously used for such purposes» behaves = moderately soft plastics "

The hiring offers a solution to this problem a two basic measures "both of which are separate alone are able to present a complete solution of the task, but in connection with other essentials to = » clauses offer advice «

One measure consists in ₉ apart from the thinner wall part at the upper end of the sleeve-shaped plug also at the lower edge of the sleeve-shaped wall

a second massive annular reinforcement as
To train transition to the top part of the plug
and on the inside of the egg-shaped wall of the sleeve
Axial stiffening ribs arranged in the plug can be seen, which essentially, in contrast to the previously known clusters of this type, dry out from the upper strengthening ring to the lower strengthening ring, while "the stiffening ribs known up to now have simply stiffened the plug wall" represent the ver ~ fixed on the reinforcement rings at both ends
Stiffening ribs now represent resilient elements "which especially in the middle part of the sleeve-shaped plug wall this, spring"! Press against the inner surface of the bottle neck. This resilient effect can be significantly increased by the fact that the sleeve-shaped wall of the stopper merges into the lower reinforcing ring via a second outer wall part, the thickness and length of this second thinner v / and part soli be .It "corresponding to the desired mechanical Anfangsäruck with what-sm, the sleeve-like 'of the ./and. die' plug against the interior-· = area of the bottle neck printed _s are set ο.

The sweite fundamental © measure is based on the ■ surprising finding _? that the surface = material of relatively hard plastic by

Understand and stretch dan not significantly soften completely cooled down leaves _β one has the possibility of such a softer surface layer, so you can ggfο the system pressure of the sleeve-like plug '' wall hold against the inner surface of the bottle neck slightly lower than at a fixed surface of the Pfropfenvrand " Therefore, after the innovation, the upper one can also be thinner

en. f ', / and part of the sleeve-shaped plug wall on the outer surface as an undercut, and in the actual sealing ring protruding outward in a ring-like manner. area of the sleeve-shaped plug wall below the upper thinner ί / and part the surface material a.xi &? . stretched ^{downwards to form a sealing layer 1 that is} softer than the other parts of the closure and

Through both Haßnahmen a relatively thin "can wall-owned r yet fully dense Flaschenver * = Closing created ,, of the appeals inside the Wrong prevailing pressure so ₉ that fer by the internal pressure: more tightly squeezed his Sits' is while he is putting sum on the bottle

As shown in the drawing, the mustard shape V / and 1 of the plug reaching into the bottle neck is designed to "press against the inner surface of the bottle neck". The lid part 2 is with the inner side. the sleeve 1 -connected "the / else is in this V to a CLOSED" Senen lochfreieti grafting * The cross over the Piasehenöffnung Aussenraantel of the closure is at β 3 _S ge 'shows * From the drawing it can be seen that at the upper

1 bands of the sleeve-shaped plug wall a continuous ring-shaped reinforcement β is arranged ₉ which is advantageously connected to the sleeve via a tapering V / and piece 6 in order to achieve the necessary flexibility between the ring-shaped reinforcement 6 and the inner sleeve also a second ring-shaped reinforcement shown at 4, that with the lower one

End of the sleeve! Connected and is _o these gain is with the sleeve 1 advantageously "connected young wall portion 5" on one hand, ver The Orösse the mechanical 'output pressure with which the sleeve-shaped Pfropfenwand 1 presses against the inner surface of the Piaschenhalses, the of material during Entferften of the closure from the mold 5 are "determined in this' by the thickness and length of this wall ^part: else the closure is in shape out <forms *" that, when the closure is at nor suitable high Ülemperatur *, for example, at a Temperature of about 60 to 70 ° C from the l? Orm is removed, its material from .aus s er en, part of the htilsenförraigsn plug wall 1 stretches partially to the lower end of the sleeve-shaped plug wall 1 or «, provides and orwi or to the lower, tapering wall piece connected to it.

When the material moves like this, ^M cold flows% v / irä. on the adjusting © where it has moved, a softer elastic Materiallag® constructed _t which applies closely to the contours of the bottle neck, ₉ extending annular construction due to the rigid BlastiEität ä @ m Verschlussauf <= construction, "in particular from the - Reinforcements β and 4 result - and partly through the effect of the pressure ^ exerted by the bottle on the closure in its position of use.

which is essentially impermeable to carbon dioxide.

In the example shown, the axxf the 'closure created® layer of softer material and the ring-shaped reinforcements 4 and 5 and reinforcement © «ribs S and 4" work together in a particularly favorable way to ensure good sealing properties and to create a substantial elastic stiffness "which presses the dl® plug-clamp with considerable force against the inner surface of the bottle neck." On the other hand, the pressure inside the pasche also supports the closure in its sealing effect, and the layer of soft material then becomes partially diverge and press tightly and equally massively against an area as large as possible on the inside of the bottle neck of the bottle neck a © Employees attempt © have shown »that one after the? The property of a bottle stopper manufactured in hiring has the property "to create a tightly sealed stopper ₉ so that when the stopper is used," for example, carbonated drinks can be stored and kept for long periods of time?
