Definitions

  • the invention relates to a closure cap with tamper-evident ring, which has a connecting ring connected to the cap and a ring with the connecting ring hingedly connected tabs, which are against a restoring force at an acute angle against the inner peripheral surface of the connecting ring can be adjusted.
  • the invention furthermore relates to a method for producing a bottle closure in which such a closure cap with a tamper-evident ring is produced and demoulded by plastic injection molding, and the tongues are then set against a restoring force at an acute angle against the inner peripheral surface of the connecting ring.
  • the invention finally relates to a method for closing a container opening, which has a neck and one or more radially outwardly directed projections around the neck, by means of such a closure cap with tamper-evident ring, wherein the closure cap, in particular by means of screws, is applied axially on the neck of the container and wherein the tabs are made in contact with the projection around the neck against the restoring force against the inner peripheral surface of the connecting ring and engage by means of the restoring force when reaching a detent position under the projection around the neck.
  • Closure caps with tamper-evident ring of the aforementioned type are used for sealing containers, in particular bottles, for the storage of food or medical preparations for use.
  • the under the projection around the neck engaging tabs form a kind of barb and block axial removal of the tamper-evident ring.
  • the tamper-evident ring is further connected to the closure cap such that the connection is perceptibly separated when the closure cap is first opened.
  • the separation may be partial or complete, leaving the tamper evident ring on either the cap or container. In any case, the partial or complete separation identifies an already opened container in order to distinguish it from original sealed containers.
  • the tabs are after injection for the purpose of easy removal regularly not in a position at an acute angle to the inner peripheral surface of the connecting ring and are therefore subsequently bent around a hinge connection to the connecting ring in the cap inside against the inner peripheral surface of the connecting ring.
  • the bending counteracts a restoring force due to the material elasticity and geometry. It has proven to be disadvantageous when closing container openings with such a closure cap that this restoring force has an axial downward component, which makes it difficult for the first time to close the container with the closure cap.
  • the tabs tend to bend due to the restoring force, so that a cap attached to the container opening must first be pressed axially until, for example, in the case of a screw cap, the threads engage in the closure cap and at the neck of the container.
  • This can be a problem when capping stations of bottling plants are not adapted to apply an axial "head pressure" to the first overcome axial downward component of the restoring force until the thread engages.
  • the object of the invention is therefore to further develop a closure cap with tamper-evident ring, a method for the production thereof and a method for closing a bottle opening such that this closure cap can be applied to the container opening in a simple and process-reliable manner.
  • the cap according to the invention with tamper-evident ring is characterized by locking means, behind which the tabs, preferably with their free end, can be latched in a detent position which is engaged against the inner circumferential surface of the connecting ring.
  • the method for producing a bottle closure of the type mentioned is inventively further developed in that the tabs are bent after plastic injection molding against a restoring force at an acute angle to the inner peripheral surface of the connecting ring or hired until they engage behind the locking means.
  • the method for closing a container opening of the aforementioned type is further developed in that the tabs are first made against a restoring force at an acute angle to the inner peripheral surface of the connecting ring until they engage behind the locking means before, in particular by means of screws, axially on the Applied neck of the container is, wherein the tabs are made in contact with the projection around the neck further against the connecting ring and finally engage by means of the restoring force when reaching a detent position under the projection around the neck cross.
  • the tabs are preferably not yet completely set against the inner peripheral surface of the connecting ring, so that an acute angle ⁇ 1 > 0 ° remains between the tab and the inner circumferential surface, by which the tabs can be further elastically adjusted. This is done when applying the cap on the neck of the container until the tabs can engage when reaching the locking position under the projection around the neck cross, the restoring force moves them radially outward.
  • the "Arretiansslage” is therefore defined by the acute angle ⁇ 1 ⁇ 0 ° relative to the inner circumferential surface under which the tabs remain latched behind the locking means, defined.
  • An “acute angle” or “acute angle of attack” is expressly understood as meaning an angle ⁇ 1 which, although not necessarily preferred, includes the limiting case 0 °.
  • the “detent position” is the axial position where the tabs snap under the protrusion around the neck. In the latching position, the tabs can assume an angle of attack ⁇ 2 ⁇ ⁇ 1 ° with respect to the inner peripheral surface of the connecting web.
  • the locking means are formed by a arranged on the cap or the connecting ring projection, which is particularly preferably designed annular.
  • the projection has a free end, which preferably faces the tabs substantially axially downwards.
  • the tabs have a radially inwardly directed in the against the inner peripheral surface of the connecting ring position inwardly directed paragraph.
  • the tabs at an acute angle interconnected, long and short legs, with a free end of the short leg forms the paragraph, beyond which projects the free end of the long leg.
  • This configuration in cooperation with the projection around the neck of the container, advantageously ensures that when the container opening is closed, the tabs engage with their shoulder under the projection.
  • the closure cap particularly preferably has a screw closure which cooperates with a corresponding thread on the neck of the container.
  • closure cap provides that radially inwardly projecting stop elements are arranged on the inner peripheral surface of the closure cap or of the connecting ring, the minimum Define the angle of attack of the tabs. In this way, the radially inwardly directed restoring force can be increased or adjusted as needed.
  • the connecting ring is integrally connected via connecting webs with the closure cap.
  • the connecting webs form predetermined breaking points at which the connection between the cap and the tamper-evident ring is irreversibly separated when the cap is first opened.
  • FIGS. 1 and 3 show a perspective view and a sectional view of the cap 10 according to the invention with tamper-evident ring 12, after the injection molding but before the bending of the tabs.
  • FIG. 4 shows an enlarged detail of the detail "A" of the tab.
  • the tamper-evident ring 12 has a connecting ring 14, at the opposite axial end of the cap a plurality of tabs 16 are arranged hingedly connected by means of a hinge connection 17.
  • the closure cap 10 is connected to the connecting ring 14 via integrally formed connecting webs 18.
  • the connecting webs 18 form predetermined breaking points, which are set up to tear off during the first opening of the closure cap.
  • the tabs 16 form a circumferential ring.
  • the articulated connection 17 between the individual tabs 16 and the connecting ring 14 is formed by a relatively thin-walled plastic portion which integrally connects the tabs with the connecting ring.
  • the tabs 16 close after injection for ease of demolding in an axial continuation of the connecting ring 14 and are then around the hinge 17 to the connecting ring 14 initially radially inwardly toward the central axis M of the cap and then into the cap interior against the inner peripheral surface 19th of the connecting ring 14 bent until they are employed at an acute angle ⁇ 1 against the inner peripheral surface of the connecting ring 14, engage in a radially outward movement behind locking means, taking their Arret istslage.
  • FIG. 2 shows the cap with tamper evident ring according to FIG. 1 after bending the tabs again in perspective
  • FIG. 5 a sectional view of the same
  • FIG. 6 an enlarged detail of the detail "A" of the bent tab.
  • the tabs 14 are employed in the locking position at an acute angle of attack ⁇ 1 to the inner peripheral surface 19 of the connecting ring 14.
  • the locking means are formed as a projection 20.
  • the projection 20 has a free end, which preferably faces the bent tabs 16 substantially in the axial direction.
  • FIG. 7 shows a sectional view of the attached to a container opening cap with tamper evident ring and FIG. 8 an enlarged detail of the detail "A" from FIG. 7 ,
  • a container 22 is shown with an opening pointing to the left in this illustration.
  • the container 22 has a tapered neck 23, which has at its upper end an external thread 24 for a screw connection with the closure cap 10.
  • the closure cap 10 accordingly has an internal thread 26.
  • a radially outwardly directed annular projection 28 which forms an edge 30 under which the tabs 16 engage in engagement in the manner described below when the closure cap 10 with the tamper-evident ring 12 is screwed onto the container opening.
  • FIGS. 7 and 8 show the tab 16 while against a radially inwardly directed restoring force at an acute angle ⁇ 2 ⁇ ⁇ 1 against an inner peripheral surface 19 of the connecting ring 14 is made.
  • the tab 16 has a long leg 34 and a short leg 36 which are interconnected at an acute angle.
  • the free end of the short leg 36 forms a shoulder 38, beyond which the free end of the long leg 34 protrudes. This shoulder 38 engages in the illustrated locking position under the edge 30 of the annular projection around the neck 23 of the container 22nd
