Definitions

• the invention relates to a screw cap with a security and guarantee tape for rapid.
• the security tapes consist of a section in the shape of a cylinder jacket, which is connected to the lower edge of the jacket of the screw closure by connecting webs.
• the bands can have weakening areas on their circumference, which tear when they are opened for the first time.
• the band sections remain connected with the screw cap. But they can also be made in one piece and remain after opening for the first time below a retaining rib, which is located axially below the thread on the snap neck.
• the object of the present invention was to create a safety band which can be applied to the bottle without problems on the bottler on high-performance filling machines and which, when the bottle is opened by the consumer, is properly separated from the screw cap and remains on the bottle neck below the retaining rib or at Reusable bottles tear and remain connected with the screw cap.
• This object is achieved by a security and guarantee tape according to the features of claim 1.
• the axially staggered retaining cams cause considerably lower spreading forces on the safety belt when it is being unrolled and prevent its premature destruction.
• Two retaining cams arranged in pairs and axially offset from one another also slide one after the other over the retaining rib when the screw cap is screwed on, as a result of which the safety band, due to the oval deformation, is hardly stretched and a small axial contact force is necessary to enable the retaining rib to jump over.
• the two retaining cams at the top are initially held back by the retaining rib, and tensile forces only occur there on the connecting webs, which are preferably formed on the side of the retaining cams, and tear them through.
• the next retaining cams reach the retaining rib and tear through the neighboring connecting webs. This avoids an inclined position of the safety band and, if formed in one piece, it always remains on the bottle neck below the retaining rib.
• a security band with a predetermined breaking point and connection to the screw cap remains attached to the latter.
• FIG. 1 shows an axial cross section through a screw cap with a security and guarantee band and underneath the neck of a PET bottle
• Figure 2 shows a cross section along line 11-11 between the lower edge of the jacket of the screw cap and the upper edge of the
• FIG 3 shows a cross section along line II-II through the security tape in Figure 1 while unscrewing the lid
• Figure 4 is a perspective view of the closure unit
• Figure 5 shows a cross section along line III-III between the lower edge of the jacket of the screw cap and the upper edge of the
• FIG 6 is a perspective view of another embodiment of the invention with a connected security tape.
• FIGS. 1 and 2 a closure unit consisting of a screw closure 2 and a security band 3 is shown schematically with reference number 1.
• the closure unit 1 is made of thermoplastic material and is produced by injection molding.
• the screw cap 2 comprises a base 4 on which a sealing rib 5 running concentrically to the axis of symmetry A can be attached.
• the design of the screw cap 2 is generally known and is not explained in more detail here.
• the security and guarantee tape 3 is connected to the lower edge 8 of the jacket 6 of the screw cap 2 by means of very thin webs 9 which are a few tenths of a millimeter thick.
• the length of the connecting webs 9 or the distance between the upper edge 10 of the security band is very small and is of the order of a few tenths of a millimeter.
• the retaining cams 12a and 12b and the retaining cams 13a and 13b are located diagonally opposite one another, are offset by approximately 90 ° and are offset axially, ie with respect to the axial extent of the security band 3, by an amount a.
• the retention cams 12a and 12b are consequently closer to the lower edge 14 of the security band 3 than the retention cams 13a and 13b by the amount a.
• the distance a is preferably less than the height b of a circumferential retaining rib
• neck 16 one e.g. Bottle made of PET 17.
• the connecting webs 9 lie between the retaining cams 12a, 12b; 13a, 13b.
• film-like connections could also hold the screw cap 2 and the security band 3 together.
• the security band 3 of the first exemplary embodiment is explained below with reference to FIG. 3.
• the closure unit 1 When the bottle 17 is closed with the closure unit 1, the latter is placed axially from above onto the bottle neck 16 and, viewed from above, rotated clockwise. Initially, the threaded sections 7 on the screw cap 2 come into engagement with the threaded sections 18 on the bottle neck 16. After approximately one revolution through 360 °, the bevelled lower edges 19 of the retaining cams 12a and 12b come into contact with the inclined upper edge of the retaining rib 15 on the bottle neck 16.
• the two retaining cams 12a and 12b are pulled radially inwards again, because at this moment the two axially offset retaining cams 13a and 13b are now also in contact with the retaining rib 15 arrive and are pushed radially outward analogously to the other two ribs.
• the cross section of the security band 3 in turn becomes oval.
• the two retaining cams 13a and 13b also slide over the retaining rib 15 and are then, like the two retaining cams 12a and 12b, in the cylindrical region 20 of the bottle neck 16.
• the thin connecting webs 9 only become very little mechanically stressed because the axial pressure causes the safety band 3 with its upper edge 10 to rest against the lower edge 8 of the jacket and the connecting webs 9 are only compressed.
• the safety band 3 is again oval-shaped and thereby pulls those which are now engaged Retaining cams 12a, 12b under the retaining rib 15. The remaining connecting webs 9 are torn.
• the safety band 3 now remains in the area 20 below the retaining rib 15. Without the safety band 3 which has now been torn off, the screw cap 2 can be screwed onto the neck 16 of the bottle 17 in order to close it again.
• the security band 3 is permanently connected to the jacket 6 of the screw closure 2 in the area (X).
• the remaining circumferential area of the security band 3 is fastened to the lower edge 10 by the thin connecting webs 9.
• a predetermined breaking point 22 in the form of an incision, a line of weakness or a film-like reduction in the wall thickness enables the security band 3 to tear when the screw closure 2 is opened.
• a first retaining cam 12a is located adjacent to the predetermined breaking point 22 below the connecting area X.
• A is preferably directly opposite the connecting area X.
• single or a pair of closely spaced retention cams 12b formed. Two further retention cams 13a, 13b are offset by 90 °.
• the retention cams 13a or 13a and 13b are located axially further away from the lower edge 14 of the safety band 3 and therefore come into contact with the retention rib 15 earlier than the retention cams 12a, 12b when opened.
• the webs 9 on the side of the retaining cams 13a and 13b and the predetermined breaking point 22 are therefore torn in front of the others.
