Definitions

  • the invention relates to a stopper for a container with a lid whose edge is connected to a peripheral wall surrounding the neck of the container, and with an annular seal, preferably an olive seal provided with an outer peripheral annular bead for clamping engagement in the container opening.
  • an annular seal preferably an olive seal provided with an outer peripheral annular bead for clamping engagement in the container opening.
  • a circumferential tear-off safety ring can be formed to protect the originality of the container contents with inwardly pointing blocking projections, which engage under an outwardly pointing annular projection of the container when the stopper is in the fastened position.
  • the ring seal preferably the olive seal
  • the dimensions are such that the olive seal is an interference fit in the container neck.
  • this press fit makes it more difficult to pull the stopper off the container or to lever it off in an inclined position, which can become a problem if the olive seal is stuck in such a tight press fit in the container neck due to unavoidable manufacturing tolerances of the stopper and/or the container that considerable force is required to separate the peripheral wall formed on the lid and the olive seal from the container neck separate. This can become an unsolvable problem for people with little strength in their hands.
  • the annular seal preferably the olive seal
  • the annular seal has a corrugated wall surface on its inside, which is formed by a large number of grooves in the wall of the olive seal running in the longitudinal direction of the plug.
  • This design ensures that when the stopper is levered off the container neck at an angle, the olive seal is compressed on the side of the force application, with the width of the grooves being reduced, with the result that the clamping force of the olive seal is reduced and the plug is easier to remove from the Container can be pried off at the side.
  • the corrugated wall surface has less of an effect on the contact pressure in the closed position of the stopper in the container, so that the olive seal with its smooth outer surface can ensure the tightness of the container contents. This is the lateral levering of the olive seal to remove the plug from the container considerably easier, the contents of the container being sealed until then.
  • the grooves have a constant shape and depth in the longitudinal direction.
  • the width and/or depth of the grooves varies in the longitudinal direction, for example increasing towards the edge of the olive seal, in order to further facilitate removal of the plug.
  • the grooves should have a depth of 10% to 50% of the minimum wall thickness of the olive gasket.
  • the ring seal according to the invention can be part of a stopper whose lid has a continuous circular shape, the olive seal being formed radially inside the peripheral wall of the lid, as is the case with conventional stoppers.
  • the olive seal according to the invention can also be part of a stopper, in which the cover contains a circular concentric depression channel which contains a radially outer annular wall and a radially inner annular wall which are connected by a bottom wall, the radially outer annular wall being shaped as an olive seal, which has the corrugated wall surface on its radial inside.
  • the corrugated inner wall surface of the olive seal means that the force required to pry off the stopper at an angle is reduced, while a sufficiently high contact pressure when the stopper is seated in the container neck is ensured despite the corrugation.
  • the ring seal can also have a barrel shape.
  • a circumferential tear-off safety ring is formed to protect the container contents from tampering with inward-pointing blocking projections which, in the fastening position of the stopper, engage under an outward-pointing ring projection of the container.
  • This tamper-evident ring ensures that the contents of the container cannot be tampered with.
  • the stopper is expediently made of LDPE, without the invention being restricted to this.
  • figure 1 shows an olive seal with a smooth outer surface 1 with an outer circumferential annular bead 2 and a smooth cylindrical inner wall surface 3.
  • the inner wall surface 4 of the olive seal 7 according to the invention is corrugated in that a large number of grooves 5 running in the longitudinal direction of the plug are formed in the wall.
  • the webs 6 remaining between the grooves have a curved cross-sectional shape.
