Definitions

  • the present invention relates to a screw cap consisting of a spout with an external thread and at least one retaining element and a screw cap with a shell wall with internal thread, which meshes with the external thread of the spout and aligned over predetermined breaking points, arranged under the jacket wall of the screw cap guarantee strip, which with the at least one retaining element on the spout cooperates.
  • Screw caps with a guarantee band have been known for many years.
  • the guarantee band should be recognizable that the contents of a container, which is closed with the corresponding screw cap, is intact. Accordingly, it is often spoken of an opening guarantee. Screw caps of this type have been known for many years. Just as long, however, the problem is known that these guarantee bands already during demoulding from the injection mold or in the subsequent
  • the guarantee strip has an annular holding bead which engages behind a corresponding holding bead or an annular groove on the spout part.
  • the screw cap is aligned with the guarantee band over the spout, and then axially moved downward, wherein the internal thread of the screw cap on the external thread of the spout slides over each other in a ratchet-like manner.
  • the guarantee strip is widened by the thickness of the retaining bead, with relatively high forces are required.
  • the predetermined breaking point bridges are on the one hand compressed and on the other hand displaced radially outward by the expansion. Here it often happens that part of the predetermined breaking point bridges is destroyed. Accordingly, this must be monitored to remove reject production from the line.
  • Predetermined breaking point bridges conditionally. Accordingly, predetermined breaking point bridges have already been destroyed during assembly here.
  • a screw cap of the type mentioned in that three to five radially outwardly directed retaining elements in the form of Posts are arranged, which at least in the twisting direction to the installation coming retaining surfaces which cooperate with arranged on the guarantee strip abutment surfaces, wherein the guarantee strip, in which abutment surfaces adjacent area each has a cross section of the guarantee strip reducing bending zone, and further that the predetermined breaking bridges as far as The bending zones are arranged away that here no relative displacement occurs during the deformation of the guarantee strip.

  • the inventive screw cap which is generally designated 1, consists of two separately manufactured parts which are shown here in the assembled state. This is on the one hand the spout or spout 2 and on the other the screw cap 3, which is connected to a guarantee strip 4.
  • the spout or spout is shown here as a separate part with a terminal flange 22, as it is for example applied to a liquid packaging made of a multilayer film produced packaging or on a tubular bag of pure Plastic film can be welded.
  • the spout or spout 2 may also be part of a plastic bottle, the spout practically corresponds to the bottleneck.
  • the spout 2 consists of a cylindrical tube section 20 which is provided with an external thread 21.
  • this cylindrical pipe section of the terminal flange 22 is formed.
  • This flange is used for adhesive bonding or welding connection with the appropriate container.
  • a circumferential collar 23 is formed at this circumferential collar.
  • radially outwardly projecting retaining elements 24 are formed, which here have the form of posts.
  • the screw cap 1 is equipped with four such retaining elements or posts 24. The number of these posts 24 is preferably chosen between 3 and 5.
  • the guarantee strip may change too large in shape during assembly, so that the security that the predetermined breaking bridges will no longer be damaged during In the case of a number of bridges over 5, the deformability of the guarantee strip is too severely restricted and, in turn, there is likewise the risk that the predetermined breaking point bridges break during assembly.
  • FIG. 3 the guarantee strip according to the invention is shown in FIG. 3a once from the outside and in FIG. 3b from the inside, both times in unwinding.
  • the guarantee strip 4 is connected to the screw cap 3 only via the predetermined breaking point bridges 40.
  • the guarantee strip itself has sections of different heights.
  • the upper edge 42 extends at three different heights.
  • the sections with the lowest height form the so-called bending zones 43.
  • the areas with the greatest height form the support zones 44.
  • the sections 45 are zones in which the predetermined breaking point bridges 40 are arranged.
  • radially inwardly directed walls 46 which are designed as abutment surfaces and between those in the guarantee position before the first opening the posts or retaining elements 24th lie. These walls 46 serve as abutment surfaces for the posts and are mainly provided because the guarantee strip is made extremely thin.
  • the wall of the guarantee strip 4 is made thicker except in the bending zones 43, these radially inwardly directed walls 46 are unnecessary. However, these optionally inwardly directed walls 46 are advantageous because the corresponding posts 24 can be made correspondingly shorter and thus do not have to protrude outside the contour of the guarantee strip 4. This can be seen most clearly in the figure 5. In this figure, it is also seen that the outer end face 47 of the posts 24 on the one hand from the inside to the outside and from top to bottom inclined or curved. This design is therefore chosen so that when placing the screw cap 3, in which the internal thread of the screw cap and the external thread of the spout are ratchet-like pushed over each other, the guarantee strip 4 does not hit the post.
  • the height of the wall of the guarantee strip is designed differently high in the guide shape shown here, and so the various zones are formed. But it is also quite possible in addition to these differences in height to make the guarantee strip 4 so that the strip thickness in the region of the bending zone 43 is substantially thinner than in the other zones.
  • FIG. This illustration shows the guarantee strip 4 in its maximum deformation during placement of the screw cap on the spout 2.
  • the guarantee strip 4 if four posts are present as shown here, approximately square deformed.
  • the spout 2 can form the bottleneck of a plastic bottle and in this case the posts 24 are formed on this bottleneck.
  • the spout 2 is provided with a flange 22 for welding or gluing with a flexible container and in this case, the aforementioned posts 24 are formed on this spout or spout, as is particularly clear from the Figure 5 can be seen.

Abstract

Dans les fermetures à vis (1) constituées d'un goulot verseur (2) sur lequel est posée une capsule à vis (3) munie d'une bande d'inviolabilité (4), des ponts à points de rupture (40) formés entre la bande d'inviolabilité (4) et la capsule à vis (3) sont exposés à un risque de destruction prématurée lors du démoulage hors du moule à injection ou lors de la pose axiale sur le goulot verseur. Selon l'invention, des tenons (24) faisant office d'éléments de retenue sont agencés sur le goulot verseur (2). Ils s'engagent dans la bande d'inviolabilité (4) avant la première ouverture. La bande d'inviolabilité (4) comporte pour sa part des zones de flexion affaiblies (43) dans des parties qui sont poussées vers l'extérieur par les tenons lors de la pose axiale. Les ponts à points de rupture (40) sont agencés aux endroits où la bande d'inviolabilité (4) croise le bord inférieur de la capsule à vis (3) pendant la pose et lors de la déformation maximale de la bande d'inviolabilité (4). La bande d'inviolabilité peut présenter, outre les zones de flexion affaiblies (43), des zones d'appui plus hautes (44), tandis que les sections (45) se trouvant entre lesdites zones présentent une hauteur moyenne.
