  Behälterverschluss 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Wie aus Fig. 1 und 2 ersichtlich, besteht der Behälterverschluss aus elastomerem Material aus einem peripheren Wulst in dem die   Umfangsnut --2- zur   dichtenden Aufnahme des offenen 
 EMI2.1 
 ausgebildet, dass bezogen auf den Axialschnitt, an der Oberseite nicht nur ein anderer
Krümmungsradius, sondern auch ein anderer Krümmungsmittelpunkt wie der an der Unterseite des
Deckels aufscheint. Die   Krümmung --7-- der   Oberseite des Deckels ist scharfkantig ausgebildet, also gross, während die   Krümmung --8-- an   der Unterseite in einem weichen Bogen verläuft und somit bezogen auf die Materialstärke verhältnismässig klein ist.

   Die obere Schnittkontur des Deckels verläuft also im Bereich des   Überganges-6-zwischen Kuppel-5-und Randzonenteil-4-nicht   parallel mit der Schnittkontur der Unterseite. 



   Die   Kuppel --5-- ist   in Ruhestellung aufwärtsgerichtet, und kann durch Fingerdruck in eine konkave Stellung abwärtsgedrückt werden. Durch die erfindungsgemässe Beschaffenheit des überganges ergibt sich der Effekt, dass in abwärtsgestülptem Zustand der Kuppel, die   Innenwand --2a-- der     Umfangsnut--2-mit   gegenüber der Ruhestellung vergrösserter Kraft gegen den inneren
Umfangsrand des   Behälterkörpers-3-druckt,   und so eine optimale Abdichtung des Behälters gegen das Auslaufen von Flüssigkeiten gegeben ist. 



   Dieser Effekt ist durch die scharfkantige Beschaffenheit der   Krümmung --7-- im  
Zusammenhang mit der Materialschwächung durch die   Krümmung --8-- an   der übergangsstelle begründet, weil sich beim Niederdrücken der Kuppel der Winkel zwischen Kuppel und Randzonenteil an der übergangsstelle verringert, indem sich der Randzonenteil abwärts krümmt und zwar hauptsächlich im unmittelbar dem Übergang benachbarten Bereich, während der, dem Übergang unmittelbar benachbarte Teil der Kuppel an der Abstülpung nicht teilnimmt, und einen nach oben gerichteten ringförmigen   Wulst --9-- bildet.

   Je   geringer die Biegefestigkeit im Bereich des überganges gegenüber der horizontalen Steifigkeit der übrigen Zonen des Deckels, desto kleiner wird der Winkel zwischen Randzonenteil und der angrenzenden Wulstfläche und desto grösser ist die horizontale Materialverzehrung. Die Grösse dieser horizontalen Materialverzehrung ist am besten dadurch zu erkennen, wie gross der Abstand X im Verhältnis zum Abstand Y ist und ist das Mass für die Kraft, die die   Nuteninnenwand--21a-auf   den Innenrand der Behälterwandung ausübt, wie auch für die Stabilität der Stülpung gegen Zurückspringen der Kuppel in die Normallage.

   Durch die von der Materialschwächung initiierte Abwärtskrümmung des Randzonenteiles ergibt sich weiters eine partielle Erhöhung der Andrückkraft im unteren Bereich der Nutinnenwandfläche, wobei sich ein zusätzlicher Dichtungseffekt ableitet. 



   Der letztgenannte Effekt kann auch durch die in den Fig. 3 und 4 gezeigte Ausführungsvariante erreicht werden, bei der der ringförmige Randzonenteil--4-vom inneren vertikalen Kreisring des Wulstes-l-gebildet wird und der   übergang --10-- ebenfalls   mit verschiedenen Krümmungen - 11 und 12-ausgebildet ist. 



   Durch die geringe Biegefestigkeit des überganges erfolgt an dieser Stelle ebenfalls eine grosse Materialverzehrung, demgemäss wird auch ein kleiner Abstand X erhalten, der dem Mass der Wölbungstiefe entspricht. Je geringer die Wölbungstiefe im Vergleich zum Ruheabstand Y, desto grösser ist die Anpresskraft der   Nutfläche-2a-an   die Innenfläche des Behälterrandes und desto höher die Stabilität der Stülpung gegen Zurückspringen in die Normallage. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Container closure
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   As can be seen from Figs. 1 and 2, the container closure made of elastomeric material consists of a peripheral bead in which the circumferential groove --2- for sealingly accommodating the open
 EMI2.1
 formed that based on the axial section, not just another on the top
Radius of curvature, but also a different center of curvature like the one at the bottom of the
Lid appears. The curvature --7-- of the top of the lid is sharp-edged, i.e. large, while the curvature --8-- on the underside runs in a soft arc and is therefore relatively small in relation to the material thickness.

   The upper cut contour of the cover therefore does not run parallel to the cut contour of the underside in the area of the transition-6-between dome-5-and edge zone part-4-.



   In the rest position, the dome --5 - is directed upwards and can be pushed down into a concave position by finger pressure. The inventive nature of the transition results in the effect that when the dome is turned downwards, the inner wall --2a - of the circumferential groove - 2 - with an increased force against the inner wall compared to the rest position
The peripheral edge of the container body-3-prints, and so an optimal sealing of the container against the leakage of liquids is given.



   This effect is due to the sharp-edged nature of the curvature --7-- im
Connection with the material weakening due to the curvature --8-- at the transition point, because when the dome is pressed down, the angle between the dome and the edge zone part at the transition point is reduced, as the edge zone part curves downwards, mainly in the area immediately adjacent to the transition, while the part of the dome immediately adjacent to the transition does not take part in the bulge and forms an upwardly directed annular bead --9--.

   The lower the flexural strength in the area of the transition compared to the horizontal stiffness of the other zones of the cover, the smaller the angle between the edge zone part and the adjacent bead surface and the greater the horizontal material consumption. The size of this horizontal consumption of material can best be seen by how large the distance X is in relation to the distance Y and is the measure of the force that the inner wall of the groove - 21a - exerts on the inner edge of the container wall, as well as of the stability the eversion to prevent the dome from jumping back into its normal position.

   The downward curvature of the edge zone part initiated by the material weakening also results in a partial increase in the pressing force in the lower region of the inner wall surface of the groove, with an additional sealing effect being derived.



   The latter effect can also be achieved by the embodiment variant shown in FIGS. 3 and 4, in which the annular edge zone part - 4 - is formed by the inner vertical circular ring of the bead - 1 - and the transition - 10 - also with different Curvatures - 11 and 12 - is formed.



   Due to the low flexural strength of the transition, a large amount of material is also consumed at this point, and accordingly a small distance X is also obtained, which corresponds to the extent of the depth of the curvature. The smaller the curvature depth compared to the rest distance Y, the greater the pressing force of the groove surface-2a-on the inner surface of the container edge and the higher the stability of the eversion against jumping back into the normal position.
