Definitions

  • the invention relates to a container closure having a base part and a cap part which is connected to the base part by a hinge and is pivotable between a closed position and an open position.
  • the cap part comprises a display part which has a separable hook area which engages in the closed position behind a radially projecting shoulder of the base part.
  • the breakable webs that connect the hook area to the outer wall of the cap part are broken by the opening movement of the cap part and the hook area remains trapped in a cavity of the base part when the container closure is opened and is visible to the user through a window in a side wall of the base part.
  • the container closure is manufactured in an open position and placed in the closed position prior to assembly on the container.
  • the separable webs should be dimensioned in such a way that they can be easily broken when opening, but also not break off prematurely when the cap part is closed for the first time.
  • EP2741968 is a container closure comprising a base portion surrounding a pour opening and defining a reference axis of the container closure, and a cap portion hinged to the base portion and pivotable between a closed position and an open position .
  • the cap portion includes a base and a peripheral outer wall surrounding an inner surface of the base and extending axially from the base to a peripheral lower edge of the cap portion such that the outer wall and base of the cap portion together cover the pouring opening of the base portion in the closed position.
  • the Cap portion further includes an indicator portion having a pull tab and a hook portion, wherein the hook portion engages behind a radially projecting shoulder of the base portion in the closed position and the pull tab extends circumferentially between a first end of the pull tab which is fixedly connected to the outer wall of the cap portion and a second end of the pull tab opposite the first end and protruding from the outer wall.
  • the pull tab is formed integrally and inseparably with the hook portion and both are pulled radially outwardly together by the user to free the hook portion from the shoulder of the base portion before the cap portion is placed in the open position.
  • the shoulder of the base part must necessarily lie radially inward of the cap part and project radially outwards.
  • the container closure is manufactured in an open position and moved to the closed position prior to mounting on the container and there is a risk that the indicator member will be deformed radially outwards from the shoulder during this movement to the closed position.
  • the object of the invention is to provide a container closure of the type mentioned at the outset, which eliminates at least one of the aforementioned disadvantages of the prior art.
  • a container closure having a base portion surrounding a pour opening and defining a reference axis of the container closure, - a cap portion connected to the base portion by a hinge and pivotable between a closed position and an open position, the cap portion having a bottom and a peripheral outer wall surrounding an inner surface of the bottom and extending axially from the bottom to extending to a peripheral lower edge of the cap portion, the outer wall and bottom of the cap portion together covering the pouring opening of the base portion in the closed position, the cap portion including an indicator portion having a pull tab and a hook portion, the hook portion being in the closed position behind a radially protruding shoulder of the base portion and the pull tab extends circumferentially between a first end of the pull tab secured to the outer wall of the cap portion and a second end of the pull tab opposite the first end and protruding from the outer wall, the object is thereby achieved solved in that the shoulder projects radially inward and the hook portion projects radially outward and that the hook portion is releasably
  • the container closure is preferably made from a single injection molded piece in an injection mold in the open position and then placed in the closed position. During this first closing movement, the hook portion is elastically deformed radially inwardly from the shoulder of the base until it is able to expand again behind the shoulder. In the closed position, the cap portion is interlocked with the base portion by the pull tab and hook portion.
  • the user grasps the protruding second end of the pull tab and pulls the pull tab radially outward. Since the hook portion of the display part is held by the shoulder, the pull tab separates from the hook area. The pull tab remains firmly connected to the cap part. The cap part can then be freely moved to the open position.
  • the separable interface preferably lies in a plane perpendicular to the reference axis.
  • the separable interface between the lower edge of the pull tab and the hook portion extends circumferentially over a certain angle of more than 30°, preferably more than 45°, for example 60° or more about the reference axis of the container closure.
  • this separable interface can be formed by a tear-off line or by individual breakable webs. With the length of the interface, the axial rupture strength of the indicator part increases while the radial rupture strength remains unchanged.
  • the shoulder extends circumferentially through an angle of more than 30°, preferably more than 45°, for example 60° or more, about the reference axis of the container closure.
  • the pull tab preferably extends circumferentially over an angle of more than 45°, preferably more than 60°, for example 90° or more, around the reference axis of the container closure.
  • the fixed connection between the first end of the pull tab and the outer wall of the cap part is intended to withstand the pulling forces caused by the user and is therefore dimensioned to have a tear strength greater than 25N, in either a circumferential, axial or radial direction.
  • the peripheral lower edge of the cap part delimits a recess in which the display part is accommodated, the first end of the pull tab being firmly connected to a peripheral end of the recess and the second end of the pull tab protruding from the recess.
  • the pull tab preferably extends circumferentially over the entire width of the recess.
  • the pull tab may be detachably connected to an upper edge of the recess, for example by a tear line or frangible webs. As an alternative to this, it is also provided that the pull tab has no connection with the upper edge of the recess.
  • the outer wall has an annular lower sealing surface on the inside, which is located axially at a certain distance from the recess and in the closed position of the locking piece bears radially against an outwardly directed sealing surface of the base part.
  • One of the two annular sealing surfaces is preferably shaped as a sealing bead and the other as a sealing seat.
  • the interior space, which lies between the base part and the cap part and is encompassed by the abutting sealing surfaces, can optionally meet the requirements for an aseptic closure.
  • the base part has a hook wall which encloses the hook area on the peripheral side and on which the shoulder is formed.
  • an upper edge of the hook panel lies in a plane extending between the pull tab and the hook portion of the display member.
  • the hook wall does not impede the movement of the pull tab and contributes to a controlled separation between the pull tab and the hook area.
  • the lower edge of the outer wall has a latching projection which engages under the shoulder in the closed position. When the cap part is opened and closed again, the resistance between the latching projection and the shoulder can be overcome by applying a slight tensile force to the cap part, which signals the closed position.
  • the peripheral lower edge of the outer wall can extend over an angle of preferably more than 180°, in this example more than 260°, around the reference axis of the container closure in one plane.
  • the shoulder and the hook area of the display part are preferably designed in such a way that after the cap part has been opened, the hook area remains trapped by the shoulder in a cavity of the base part, which may be delimited radially on the outside by the hook wall and radially on the inside by another wall of the base part becomes.
  • the first end of the pull tab may be positioned in an area of the outer wall diametrically opposite the hinge. This places the pull tab furthest from the pouring opening in the open position, which is ergonomically advantageous, particularly when drinking directly from the container through the pouring opening.
