Definitions

  • the invention relates to a container closure with a lower part which extends around a reference axis of the container closure, a lid which covers an opening of the lower part in a closed position and leaves the opening open in an open position, and a display element whose state changes irreversibly when the lid is first opened.
  • a container closure of the type mentioned at the outset is known in which the display element is connected to the lid by a predetermined breaking point and has a first locking projection which, in the closed position, lies at least partially in a cavity between an outer wall and the inner wall of the lower part and has a stop surface which projects radially outwards, points axially in the opening direction, lies opposite a corresponding counter stop surface of the outer wall pointing opposite to the opening direction and is held by the corresponding counter stop surface of the outer wall when the lid is first opened, so that the first opening of the lid causes the predetermined breaking point to break.
  • this container closure there is a risk that someone could use a tool to press the display element against the inner wall of the lower part and thus displace the locking projection radially inwards, whereby the lid is first opened without the predetermined breaking point breaking.
  • a container closure differs from the ES 1277165 U differs in that the inner wall has a locking projection that projects radially outwards and axially opposite to the opening direction, and is opposite a corresponding locking surface of the display element that is aligned in the opening direction. This ensures that the predetermined breaking point of the display element does not break when the lid is first opened. However, the corresponding locking surface of the display element is protected by a second locking projection of the display element which projects radially inward so that the display element has a large radial dimension. In addition, the first opening is made more difficult by the fact that in the closed position the locking projection of the inner wall lies radially against a wall of the display element and during the first opening rubs against this wall before the predetermined breaking point breaks.
  • the invention is based on the object of equipping a container closure of the type mentioned at the beginning with means which ensure that the predetermined breaking point of the display element does not break when the lid is first opened, but without significantly increasing the radial space requirement.
  • a container closure with a lower part that runs around a reference axis of the container closure, delimits a mouth of the container closure, and has an outer wall and an inner wall that lies between the outer wall and the mouth, a lid that, in a closed position, covers the mouth of the container closure in an opening direction of the reference axis and, in an open position, provides access to the mouth of the container closure, and at least one display element that is connected to the lid by a predetermined breaking point and that has a locking projection that forms a stop surface that projects radially outwards, is axially aligned in the opening direction and is opposite a corresponding counter stop surface of the outer wall that is directed away from the opening direction, wherein the inner wall has a locking projection that projects radially outwards and axially opposite to the opening direction, and is opposite a corresponding locking surface of the display element that is aligned in the opening direction, the object is achieved in that the display element has a window, one edge of which forms the locking surface of the display element, wherein,
  • the indicator element If, in the closed position before first opening, the indicator element is pushed inwards in order to fraudulently release the locking projection of the indicator element from the counter stop surface of the outer wall, the locking surface of the indicator element is caught by the locking projection of the inner wall, so that the opening of the cover causes the predetermined breaking point to break.
  • the predetermined breaking point can be formed by one or more detachable bridges or a continuous detachable line of weakness.
  • the first locking projection can give way elastically during the transition from the open to the closed position before the lid is first opened.
  • the first locking projection hits the outer wall of the lower part and retracts radially inwards when passing the outer wall in order to be able to expand again when the closed position is reached.
  • the outer wall and the inner wall delimit a slot which provides access to a shaft in which the locking projection of the display element is accommodated in the closed position before the first opening.
  • the shaft accommodates the display element after the predetermined breaking point has broken.
  • the window has a further edge which is opposite the locking surface and is at such a distance from the locking surface that after the breaking point has broken, the display element can move into the gap due to gravity in a direction opposite to the opening direction.
  • the counter stop surface of the outer wall is preferably located axially between one edge and the other edge.
  • the lower part is preferably suitable for tight fastening to a container neck and is therefore equipped with fastening means, which preferably have at least one radially inwardly directed projection in the form of a locking projection or thread.
  • fastening means which preferably have at least one radially inwardly directed projection in the form of a locking projection or thread.
  • the lower part is mounted with a fastening ring which has a peripheral wall with fastening means for tight fastening to a container neck.
  • the display element In the closed position, the display element is preferably located radially outside the mouth of the base ring. Preferably, in the closed position, the display element is partially exposed radially outwards before the first opening.
  • the lid may have a locking projection which, in the closed position, engages behind a locking projection of the lower part to secure the closed position.
  • the lower part has a spout surrounding the mouth
  • the lid has an inner sealing skirt which, in the closed position, is in sealing contact with a preferably cylindrical or frustoconical sealing seat formed by the spout, wherein the sealing seat preferably points radially inwards.
  • the container closure has a hinge that connects the outer wall of the base to the lid.
  • the hinge is preferably a snap hinge.
  • the display element is preferably located diametrically opposite the hinge.
  • the lid, the hinge and the outer wall of the base are integrally connected to one another.
  • the lid, the hinge and the outer wall of the base can be manufactured in one piece by an injection molding process, preferably in the open position, and are then brought into the closed position.
  • the lower part itself can be one piece or be formed from two positively connected pieces, namely an outer piece that forms the outer wall and an inner piece that forms the inner wall.
  • a preferred embodiment of a container closure of the present invention is indicated by the reference numeral 10.
  • the closure 10 is intended to be to be mounted on the neck 12 of a container.
  • the closure 10 can be made of a plastic or other material that is compatible with the container contents.
  • a polymer is preferred here, in particular a thermoplastic such as polyethylene or polypropylene.
  • the closure 10 is preferably made in one piece in the open position of the Figures 1 and 2 sprayed, and then in the closed position of the Figures 3 to 6 brought.
  • the lower part 14 comprises an inner skirt 24 which lies opposite the outer wall 22 between the outer wall 22 and the reference axis and which delimits with the outer wall 22 an annular volume 200 which is intended to receive an upper edge 123 of the container neck 12.
  • the skirt 24 can have a peripheral sealing bead 25 and is intended, after mounting on the container neck, to come into sealing contact with a sealing seat 124 which is formed by an inner surface of the container neck 12 .
  • the lower part 14 has a spout 20 which has an opening 300 of the lower part 14 and the container closure 10
  • the spout 20 can have one or more slot-like openings 21 that provide access to a cavity 400 that is enclosed by the inner skirt 24.
  • the lower part 14 can have a flow restrictor or a valve that closes the mouth 300 .
  • the lower part 14 has an inner wall 26 which lies opposite the outer wall 22 between the outer wall 22 and the mouth 300 and can optionally be formed by an extension of the apron 24.
  • the inner wall 26 delimits, together with the outer wall 22 , a slot 27 of the lower part 14 which provides access to a shaft 28 which is optionally connected to the annular volume 200 between the outer wall 22 and the inner wall 24.
  • the inner wall 24 has a locking projection 30 which projects radially outwards and is oriented opposite to the opening direction 110 .
  • the cover 16 serves to protect the Figures 3 to 6 to cover the mouth 300 of the container closure 10 in an opening direction 110 of the reference axis 100 and in the open position of the Figures 7 and 8 to provide access to the mouth 300 of the container closure 10.
  • the lid 16 comprises a head plate 34, a peripheral wall 36 which surrounds an inner wall surface of the head plate 34 , and a gripping projection 40 which optionally protrudes from an upper edge of the peripheral wall 36 as shown.
  • the head plate 34 can be flat or curved.
  • An annular sealing skirt 42 preferably extends from the inner side of the head plate 34 and is enclosed by the peripheral wall 36 at a radial distance.
  • This sealing skirt 42 can have a circumferential sealing bead 47 and is intended to come into sealing contact with a sealing seat 44 formed by the spout 20 in the closed position.
  • the sealing skirt 42 is enclosed by the spout 20 in the closed position.
  • the container closure 10 comprises a display element 52 which is connected to the lid 16 by a predetermined breaking point 54 , which here is formed by several detachable bridges 56 (see Figure 6 ). It is provided that in one variant the predetermined breaking point 54 is formed by a continuous tear-off line of weakness.
  • the display element 52 can be flat or slightly curved and is preferably symmetrical with respect to a plane of symmetry which contains the reference axis 100. In this exemplary embodiment the display element 52 is located diametrically opposite the hinge 18.
  • the display element 52 has a locking projection 58 which forms a stop surface 60 which projects radially outwards with respect to the reference axis 100 and is directed in the opening direction.
  • the display element 52 has an inner surface 61 which faces the inner wall in the closed position. This inner surface 61 is preferably flat.
  • the display element 52 forms a window 62 with an upper edge 64 and an opposite lower edge 66 .
  • the shaft 28 is designed to hold at least a part of the display element 52 in the closed position of the Figures 3 to 6
  • the locking projection 58 of the display element hits an inclined edge 68 of the outer wall 22 of the lower part 14 and elastically retracts as it passes the outer wall until it can expand again at the latest when it reaches the closed position.
  • the locking projection 30 of the inner wall 24 elastically deforms as the display element 52 passes until it can expand again into the window 62 .
  • the display element 52 is thus both on the outside by the counter stop surface 70 of the outer wall 22 and on the inside by the locking projection 30 of the inner wall 24 , so that the first opening of the cover causes a break in the predetermined breaking point 54 , regardless of whether the display element 58 is simultaneously pressed radially inwards or not.
  • the container closure may have more than one display element 52 , e.g. two display elements which are opposite one another on either side of a plane of symmetry of the container closure which is perpendicular to the pivot axis 200 .
  • the base 14 may be a mounting ring mounted on a container neck 12 and in which a separate spout is mounted, or a spout separate from a mounting ring.
  • the lid 16 is not necessarily hinged to the base 14.
  • the lid may be hinged to a mounting ring or a spout separate from the base ring.
  • the hinge 18 may be replaced by one or more strips or may be omitted entirely.
