Definitions

  • Screw cap for tamper-evident protection, especially for wide-neck containers
  • the invention relates to a screw closure with originality assurance according to the preamble of claim 1.
  • Screw closures with tamper-evident protection for containers are generally known.
  • Such closures usually have a securing ring formed on the lower edge section of the closure cap via narrow webs forming predetermined breaking points, which engage from below a bead formed on the container neck.
  • the narrow connecting webs designed as predetermined breaking points tear, since the retaining ring cannot be moved upwards because of the bottle bead protruding outwards.
  • the locking ring is thus blasted off the closure cap and remains on the bottle neck, unless the ring itself breaks and falls off the bottle neck or is removed from it.
  • closure can already be opened by turning the cap by a certain amount, so that a vacuum built up inside the container is released, but the retaining ring itself still is not blown off. If the closure cap is then closed again, the vacuum inside the container is released, but the opening of the closure that has already taken place is not visible from the outside.
  • a container which has been opened and closed again in this way can thus be returned to the store shelf without the opening once having been controllable from the outside. It is obvious that goods opened in this way often become moldy long before the expiry date stated on the package or can otherwise spoil.
  • the object of the invention is to provide a screw closure, in particular for wide-neck containers, which has a tamper-evident device, which indicates any opening of the closure in a secure manner and furthermore avoids the rejects occurring in the previous tamper-evident closures as a result of a detached snap ring.
  • the closure cap when the closure is opened in rotation, parts of the closure cap are locked, which is irreversible and causes the occurrence of a visible or tactile tamper-evident feature on the screw closure itself.
  • This can be done for example by indenting protrusions in window-like openings or disengaging protrusions from window-like openings and interlocking tongues and recesses, the originality position can still be clarified by different colors.
  • the screw cap is discolored due to a deformation of part of the screw cap when the screw is opened.
  • This discoloration can take place by means of a color layer which is displaced under deformation into a visible section of the closure cap or by appropriate choice of material in that a material is used for the cap which discolors permanently under deformation stress. As a result, it can be determined on the screw cap or on the screw closure itself whether the closure has already been tampered with without a scrap in the form of a detached locking ring.
  • the deforming section is implemented in a particularly expedient manner by a combination of active surfaces consisting of a conically inwardly running lower edge section of the closure cap in connection with a conical inclined surface on the container neck. If the cap is pulled off by turning it upwards, the lower edge section is deformed outwards, so that the lower and section remains discolored and the opening of the closure is indicated for the first time. The closure can then be easily reused.
  • the originality feature is formed in a particularly expedient manner when it is locked between a cap and a locking member of the closure, which is thus constructed in two parts.
  • the cap sits on the locking member, which is in the rotationally engaged position with the container neck, that is to say has the screw threads.
  • the cap can be rotated on the locking element until a locking position is reached, which is achieved by locking elements on the cap in cooperation with locking on the locking element.
  • the tamper-evident feature is formed, for example by inserting or disengaging parts of the cap or the latching member into openings or Ausneh ⁇ mungen the locking member or the cap a permanent visible or tactile change in the screw cap is generated. It is advantageous here that the locking position can also be heard, so that the first user of the closure can also control the first opening by means of an audible signal.
  • the latching member now coupled is also rotated so that the closure is opened when the cap is turned further. That is, , The tamper-evident feature is formed in a secure manner immediately before the screw cap actually opens, so that manipulation of the screw cap (opening without triggering the tamper-evident device) is no longer possible.
  • the display of the tamper-evident feature in the latching position can be displayed in a variety of ways on the screw closure, for example by forming a toothing on the lower edge section of the cap, which is aligned in the latching position with a corresponding counter-toothing on the latching member, in the latching position the cap is moved downwards relative to the locking member, so that the toothing and the counter toothing come into engagement and the originality feature is thus visible to the outside.
  • Kinematic reversal is also possible by the cap of the locking element in the locking position lifted off and thus an engagement position between the cap and the locking member is canceled. This disengagement, which then forms the originality feature, can be emphasized by different colors.
  • a bead or bead-like projections in the manner of knobs are pressed through window-like openings of the other part or disengaged from them, which in turn produces a visible change in the screw closure, which forms the originality feature.
  • the locking member is designed in the manner of a cap and is made of a softer material with sealing properties, so that the locking member itself also represents the seal of the container neck.
  • one or more sealing lips can also be provided on the latching element, which in the closed position lie sealingly on surfaces of the container neck, in particular on the inner surface of the container neck in the region of the container mouth.
  • catches or catch elements can be undertaken, the catches only coming into a blocking function in a particularly expedient manner in one direction of rotation, which expediently corresponds to the rotational opening movement of the catch member and thus the opening movement of the closure.
  • a tamper-evident ring is provided between the latching member and the cap, which is initially pulled or disengaged from the closure cap via a steep thread when the closure is opened, until this ring irreversibly engages with a molded-on part in the latching ring or in the latching member, so that the closure thread is opened only when the cap is turned further.
  • the latching member forms the outer cap of the closure and engages over an inner cap which, in the closed position, rests firmly on the neck of the container, the tamper-evident feature again being irreversibly visible when opened, here by rotating the outer cap, due to latching with the inner cap.
  • saw tooth profiles are used according to the invention for the catches and catch elements, which allow the outer cap to rotate relative to the inner cap in the opening direction, but prevent relative rotation in the opposite direction, so that the outer cap is blocked with the inner cap in the opposite direction and so that the originality feature once created can no longer be undone.
  • the tamper-evident feature is advantageously achieved by covering identification fields with openings in the outer cap, the identification fields being provided on the top of the inner cap.
  • opening i.e. when the outer cap is opened in rotation, despite the engagement position due to the sawtooth-like profile, it is possible for the catches to overflow over the catch elements, so that the openings pass over the identification fields as a result of the relative rotation between the cap and the inner cap, and the originality feature is thus shown .
  • turning the outer cap back relative to the inner cap is no longer possible, so that the tamper-evident feature is irreversibly retained.
  • the labeling fields can be formed by color fields or labeled fields. Although it is expedient to provide the openings and the color fields on the cap base, it can also be expedient to provide the openings in the manner of recesses or the like on the side wall of the outer cap and the identification fields on the side wall of the inner cap. The same also applies to the arrangement of the catches or catch elements, which are an alternative to the arrangement can also be provided on the cap base on the side wall of the cap.
  • the inner cap is lifted from the container neck, with the result that the tight fit of the inner cap in the container neck is removed and thus the Inner cap is rotated with the outer cap.
  • the driving shoulder is expediently formed on a projection which projects radially inwards from the side wall of the outer cap and which holds the inner cap on the outer cap.
  • the engagement position between the sawtooth profiles or the catches and the catch elements is such that both when the driving shoulder rests on the inner cap but also in the closed position, where the catch shoulder is at a distance from the inner cap, the catch engagement position between the catches and the Locking elements is guaranteed. This is essential for maintaining the originality feature.
  • the outer cap is designed in such a way that, when it is opened, it presses the inner cap onto the container neck until the driving shoulder begins, the inner cap from Take off the container.
  • a resilient part for example a resilient lip, formed on the bottom of the outer cap, but expediently the bottom of the outer cap is bulged downward in a bulbous manner, so that the bulging with prestress on the inner cap presses.
