Definitions

  • the invention relates to a stopper for a container, which preferably has a bottle shape and is intended in particular for holding tablets, dragees or other substances, for example in powder or granule form, the stopper having a grip around the edge of the container opening, optionally the container neck , tear-off securing ring for tamper-evident securing of the container contents is provided, which with an inner projection engages under the outwardly facing ring projection of the container.
  • Such plugs whose tear-off securing ring engages under an outer annular projection on the neck of the container, for example with a bead having a frustoconical cross section, are known.
  • These stoppers have the disadvantage that, if they are made of a material of a certain flexibility, they can be “levered off” from the neck of the container without the predetermined breaking seam of the safety ring being damaged, so that they do not adequately fulfill their task of tampering with the contents of the container able to fulfill.
  • the present invention has for its object to develop a stopper of the type under consideration so that the tamper-evident content of the container is ensured with simpler, cheaper means. Furthermore a container for this stopper should be specified.
  • the stopper engages with a so-called olive in a clamp fit in the container opening and is provided with a device which, after removal of the tamper-evident ring, serves as a handle for removing the stopper from the container.
  • a slide is preferably provided for this purpose, which can be advanced beyond the lateral edge of the stopper and optionally the container neck.
  • the training can also be such that a suitable contact surface, recessed grip or grip tab etc. is exposed after removal of the locking ring.
  • the locking ring has a larger outer diameter than the head part of the plug, to which the locking ring is connected via a preferably circular predetermined breaking seam lying radially on the inside thereof, the diameter of which is thus smaller than the outside diameter of the locking ring.
  • the slide is arranged as an additional child safety device
  • the securing ring has a blocking peripheral portion, which has at its upper end a projection, preferably not connected to the head part of the plug, which projects into the feed path of the slide so that the slide cannot be advanced into the position in which it has a gripping surface for removing the plug of the container offers.
  • the slide can not be used as a handle for removing the plug as long as the tamper-evident circlip is attached, since this prevents the feed movement of the slide into its actuating position with an upper attachment.
  • the invention enables the radially inner bead of the securing ring to have a simple shape in cross section, for example the shape of a truncated cone or a triangle or an arched protruding shape, with which this annular projection can be produced in a simple and inexpensive manner by forced demolding, i.e. by an inner core of the injection mold, which is removed after the locking ring has been shaped and widened. Any "prying off” is reliably prevented by the predetermined inward-facing seam radially inward relative to the circumferential wall of the retaining ring, under the lower edge of which the force required for "prizing" would have to be applied, and by the non-releasable clamp fit of the stopper in the container opening.
  • the predetermined breaking seam can be formed by a notch or by tear-off webs.
  • the retaining ring have a substantially cylindrical peripheral wall which encloses the upper edge or neck of the container, and an annular wall which is angled inward by approximately 90 ° and which - preferably with the exception of the blocking peripheral section - over the circular circumferential predetermined breaking seam is connected to the head part.
  • the blocking peripheral portion is with the Head part of the stopper is not connected, this can be accomplished either during the injection molding process by appropriate design of the injection mold or by subsequent cutting free.
  • the annular wall of the locking ring rests in the fastening position of the stopper on the container on the upper edge of the container opening.
  • the annular wall in the area of the blocking circumferential section has a particular advantage, at least in places, a greater wall thickness than in the area of the rest of the securing ring, so that in the fastening position of the stopper the annular wall section of the blocking circumferential section is forced up, the dimensions being such that so that the advancement of the slide of the stopper over the container edge is reliably prevented as long as the locking ring with the circumferential blocking portion is fastened to the stopper.
  • This forced blocking of the slide prevents the plug from being removed without damaging the predetermined breaking seam.
  • the corner region of the blocking peripheral section in which the preferably cylindrical peripheral wall merges into the annular wall free from the head part, has a reduced cross-sectional thickness, so that the annular wall section can fold up in the manner of a film hinge.
  • the reduction in the cross-sectional thickness can be caused, for example, by a notch molded into the inside.
  • the blocking peripheral portion may have a width that substantially matches the width of the slider. It is essential that the blocking peripheral section is so wide that - because of its circular arc shape - the blocking upper wall section cannot be folded outwards in order to open the way for the slide in its actuating position.
  • the cylindrical part and the preferably circular part of the blocking peripheral section can also be connected to one another by a predetermined breaking seam.
  • the blocking circumferential section can be extended over at least one preferably vertical, i.e. predetermined breaking seam running approximately parallel to the longitudinal axis of the container may be connected to the rest of the securing ring.
  • the circumferential blocking section can be connected to the retaining ring by means of a film hinge, which is also preferably vertical and is spaced apart from this predetermined breaking seam in the circumferential direction, in order in this way to facilitate the tearing off of the retaining ring.
  • a second predetermined breaking seam can also be formed.
  • the container provided in accordance with the invention which interacts with the stopper, has an outer annular projection which interacts with the radially inner annular bead of the securing ring.
  • This ring projection of the container can advantageously have a retaining wall projecting outward at a right angle to the longitudinal axis of the container, under which the annular bead of the securing ring snaps into the fastening position of the stopper.
  • the blocking peripheral portion is not provided with the annular bead.
  • This design has the advantage that tearing open the predetermined breaking point (s) between the circumferential blocking section and the rest of the securing ring is avoided when the inner core is removed during the forced demolding. This advantageous measure does not impair the tamper-proof of the container contents.
  • the head part of the stopper expediently lies with a cylindrical base section on a recessed, circumferential annular shoulder of the container.
  • the upper edge of the cylindrical base section is flush with the upper edge of the container opening, so that the slide adjoining the cylindrical base section (viewed in the axial direction) protrudes closely over the edge of the container when the retaining ring is removed.
  • the cylindrical base section of the head part is particularly advantageously adjoined by a conical section which ends in a substantially flat upper side of the plug.
  • the design is hereby made such that there is no gripping surface in order to release the clamp fit of the stopper in the container opening, so that this is only possible when the slide is extended. This reliably prevents small children from having access to the contents of the container.
  • the slider should be substantially flush with the top of the head section so that it does not provide a gripping surface in the non-advanced position.
  • the plug according to the invention combines a reliable tamper-evident device with a child-proof device and also has the advantage of relatively simple, inexpensive manufacture.
  • a preferred material for the stopper is polyethylene, although the invention is of course not limited to this.
  • the vial according to the invention is preferably made of glass, although plastics such as e.g. Polypropylene come into consideration.
  • the stopper 1 generally contains a head part 2, in which a slide 3 serving as a child safety device is slidably inserted, a locking ring 4 with a blocking circumferential section 5 and one usually referred to as an olive Part 6, which engages in the opening of a bottle-like container 7 (Fig. 4) and is held there in the press fit.
  • the locking ring 4 of the stopper 1 contains a cylindrical section 8, which is bent inward at its upper end by 90 ° and continues in an annular section 9, which is connected to the head part 2 via a circular predetermined breaking seam 10.
  • the latter does not apply to the blocking peripheral section 5, which likewise has a cylindrical edge section 8 and an annular wall section 11 which is angled radially inward by 90 °, but which is not connected to the head part 2, but ends freely.
  • This wall section 11 which is initially also arranged horizontally after the production, merges into the cylindrical part 8 in a corner region 12 of reduced cross-sectional dimensions, as a result of which the wall section 11 can be pivoted easily, and itself has a greater wall thickness than the horizontal wall section 9 of the remaining securing ring 4.
  • the blocking peripheral section 5 is connected on the one hand by a vertical predetermined breaking seam 13 and on the other hand by a film hinge 14 to the rest of the securing ring 4, although the horizontal wall section 11 is not connected to the annular wall section 9 of the securing ring 4.
  • the locking ring 4 contains a radially inner bead 15, which has an approximately frustoconical cross section and an annular one in the fastening position (FIG. 4) outer approach 16 of the container 7, more precisely engages under a wall surface 18 which extends perpendicular to the longitudinal axis 17 of the container 7.
  • the blocking circumferential section 5 is not provided with this annular bead 15 in order to enable the forced demolding without breaking the predetermined breaking seam 13.
  • a stepped annular shoulder 19 is formed, in which a cylindrical base section 20 of the head part 2 of the stopper 1 engages in the fastening position.
  • the upper edge of the cylindrical base section 20 is approximately aligned with the upper edge of the upwardly projecting ring projection 21 of the container 7, on which the annular section 9 of the securing ring 4 and the wall section 11 of the blocking peripheral section 5 lie in the fastening position. Since the wall section 11 has a greater thickness and is connected to the cylindrical wall section 8 by a kind of film hinge, the wall section 11 of the blocking peripheral section 5 is thereby forcibly folded up and projects into the feed path of the slide 3, which is thereby prevented to become.
  • the head part 2 of the stopper 1 has, following the cylindrical base section 20, a conical section 22 which ends in a flat upper side 23 with which the slide 3 is essentially aligned. In the position shown in FIG. 4, the head part 2 of the stopper 1 and the slide 3 do not offer any contact surface in order to exert an upward tensile force on the central part of the stopper 1, with which the clamp fit of the olive in the container opening could be overcome.
  • the predetermined breaking seam 13 is torn open, whereupon the securing ring 4 can be torn off along the circular predetermined breaking seam 10. Then the slide 3 can be advanced beyond the upper edge of the container opening, which is facilitated by a recessed grip 24 in the top of the slide 3. The retracted initial position of the slide 3 is secured by a projection 25 in the bottom region of the path of movement of the slide 3, which is overcome by applying a feed force. The advanced position of the slide 3 is defined by a stop 26.
  • the upper shoulder of the blocking peripheral section can be formed by an extension of the cylindrical wall section, the "folding away" of which can be made impossible by suitable measures.
  • This wall extension can also be provided in addition to an annular wall section connected to the head part via a predetermined breaking seam.
  • the circular predetermined breaking seam lying radially on the inside in relation to the cylindrical circumferential wall forms a reliable tamper-evident device when the stopper is clamped in the container opening as long as the stopper cannot be pulled on its head part in the release direction. After removing the locking ring, a suitable contact surface, recessed grip, etc. can be exposed.
