Definitions

  • the invention relates to a container closure having a base part, a spout area and a cap part which is connected to the base part by a hinge and can be rotated back and forth between a closed position and an open position about a pivot axis running perpendicular to the reference axis.
  • a container closure of the type mentioned in which the drinking part has a peripheral wall which runs around a reference axis of the container closure and extends axially from the base part to a peripheral upper edge of the spout area which surrounds the drinking opening.
  • the cap portion has a bottom and an outer wall that extends axially from the bottom to a peripheral lower edge of the cap portion.
  • the closed position the drinking part is surrounded and covered by the cap part.
  • the cap portion lies on an opposite side from the drinking portion of a first reference plane of the container closure which contains the axis of the hinge and is parallel to the reference axis.
  • the hinge is a bistable snap hinge and is located in a groove in the outer wall of the cap portion which is a leak point of the closure.
  • the cap part has an inner skirt which extends from the bottom to an annular sealing collar, wherein in the closed position the inner skirt encloses the drinking part and the sealing collar bears against an annular sealing surface of the base part, while the peripheral lower edge of the cap part faces a shoulder of the base part.
  • a non-aseptic annular cavity is created between the outer wall and the inner skirt, which can be contaminated by the leaking snap hinge and is difficult to rinse off.
  • the high inner apron of the cap part takes up a volume that limits the design freedom for the drinking part.
  • the distance from the base part to the upper edge of the spout area and the diameter of this upper edge must be kept small so that the drinking part does not represent an obstacle when the cap part transitions between the closed position and the open position.
  • this closure requires a significant amount of plastic material.
  • the upper edge of the spout area can be made higher and wider, but the sealing of the spout area against contamination is no longer guaranteed by the gap between the hinge and the outer wall of the cap part.
  • a container closure which is compatible with aseptic sealing of a drinking portion.
  • the closure includes a base portion, a cap portion and an external hinge assembly arranged to project radially outwardly from the cap portion and base portion of the closure in the closed position of the closure and connected to each of these portions by a radially extending bridge is. This ensures that the interface between the hinge and the cap part does not show any leakage.
  • this hinge configuration requires a lot of space in the radial direction. Furthermore, it is sensitive to shock and difficult to assemble in a bottling plant.
  • a container closure with a base part and a cap part wherein the cap part is connected to the base part by a snap hinge, which has two lateral hinge tabs and a central hinge.
  • the hinge shackles are attached to free-standing webs in a stepped recess in the outer wall of the cap part or base part, these webs being able to be bent out to avoid overstretching of the hinge shackles.
  • the central hinge is attached directly to the outer wall of the cap portion, and forms a leak, so that the closure is unsuitable for aseptic use.
  • the pivot axis of the hinge is close to the outer wall and the pivoting movement of the cap part that can be achieved thereby is unsuitable for a container closure with an axially extending drinking part.
  • a container closure is already known, with a base part, a spout area which has a peripheral wall which runs around a reference axis of the container closure and extends axially from the base part to a peripheral upper edge of the spout area which surrounds a drinking opening, a cap part which connected to the base by a hinge and rotatable between a closed position and an open position about a pivot axis perpendicular to the reference axis.

  • the bridge connecting the anchor wall to the outer wall of the cap portion provides a separation between the hinge and the outer wall, allowing the outer wall to enclose the spout area without interruption and ensure aseptic protection of the spout area. Because the anchor wall extends radially outside the outer wall, the distance between the pivot axis and the reference axis is greater than the distance between the outer wall and the reference axis, thereby ensuring sufficient design freedom for the spout area.
