• the one-piece closure has a jacket wall, which is provided with an internal thread, which can be placed with an external thread on the container neck.

• the area of the sleeve-shaped structure thus comes into contact with the adhesive and various such adhesives are extremely aggressive and dissolve various plastics, especially those which are suitable for the manufacture of shells, slightly superficially. Consequently, the frequent use causes the seal in the sleeve-shaped structure loses its tightness. On top of that, a sufficient tightness too achieve such a closure and the corresponding container must be made extremely accurate mass, resulting in a relatively high reject rate. In addition, such closures and containers must be checked for dimensional accuracy during production so that no faulty batches occur in which the filled adhesive in the container hardens itself.
• the lower seal is located at the bottom of the cylindrical structure and in the lower part of the concentric around it running wall, which must have a taper as already mentioned. Depending on the type, these conicities are designed differently.

• the supply sleeve 6 has a cylindrical jacket wall 60, which is provided in the upper region with an external thread 61.
• the feed sleeve 6 thus forms a kind of tube open on both sides.
• a number of guide ribs 62 are likewise integrally formed on the outside of the cylindrical jacket wall 60 in the example shown here four. These guide ribs 62 extend axially practically over half the length of the cylindrical jacket wall 60 from the region below the external thread 61 to the lower edge.
• This sealing pin 65 has a certain conicity and has a countersink 66 at its outer tip.

• a stop element 502 is present at this practically directly on the jacket wall 50 fitting.

• FIG. 4 shows the semi-finished product according to the invention, which consists of the lower part 4 and the feed sleeve 6. These two parts are connected to each other in the position in which these two parts as a semi-finished product via predetermined breaking point bridges 600. These predetermined breaking point bridges 600 form a connection between the guide ribs 62 and the first shoulder 45 of the lower part 4 in the region of the center of the outermost edge of the notches 401. This arrangement is particularly useful because in this direction and at this point the Game between the supply sleeve 6 and lower part 4 can be greatest. Any remaining residues on the two parts after the separation consequently do not have a negative effect.
• the advantage of the semifinished product according to the invention in itself consists in the fact that as a result an injection mold is less required and, correspondingly, no further injection molding machine has to be occupied during production.
• the additional cost of the slightly larger depth of the injection mold is insignificant. Even the slightly longer Cycle time per injection process is hardly significant in comparison to the savings in particular since the semifinished product consisting of the lower part 4 and the feed sleeve 6 requires no additional use of the surface on the injection mold. Also the fact that that
• Feeding sleeve 6 without exception from bottom to top is steadily decreasing, the semifinished product can be easily demolded without a slider.
• the small outwardly projecting elevations, for example of the thread 61 or the annular beads 47, are so small that the semi-finished product can be torn out thanks to its elasticity after the injection process without defects occurring.
• Another advantage of the semi-finished product is that the relative position of the feed sleeve 6 is exactly predetermined in relation to the lower part 4 in the radial direction, and consequently a corresponding alignment of the parts is omitted in the subsequent assembly. In addition to this radial alignment of the two parts 4 and 6 to each other, these must not be aligned axially with each other. This significantly simplifies the subsequent assembly.
• the invention comprises the assembly method for the assembly of the closure according to the invention using the semifinished product, as shown in FIG.
• the two parts namely on the one hand, the upper part 5 and on the other hand, the feed sleeve 6 are aligned in the axial direction to each other.
• the central axis of the feed sleeve 6 and on the other hand, the center axis of the sleeve-shaped attachment of the upper part 5 are aligned with each other.
• the upper part 5 is held by a gripper, while at the same time in the feed sleeve or in the interior of this feed sleeve 6, a rotatable finger is inserted, which has at its upper end corresponding slots which are designed so that the supports 64, which the pivot pin 65 hold, fit into these slots form fit.
• a rotatable finger is inserted, which has at its upper end corresponding slots which are designed so that the supports 64, which the pivot pin 65 hold, fit into these slots form fit.
• One will normally insert the finger and then turn the supply sleeve 6 until the mentioned supports 64 fall into said slots. Now the entire semi-finished product is kept in the correct position.
• the upper part 5 is now fed onto the semifinished product 4, 6 and screwed with the external thread 61 into the internal thread 55 of the sleeve-shaped attachment 54 of the upper part 5.
• This screw-on movement is carried out until the guide ribs 62 on the supply sleeve 6 come to rest on the annular abutment surface 56 below the internal thread 55.
• this screwing under Monitoring the torque, so that you can be sure when reaching a predetermined torque, an exact radial alignment of the feed sleeve 6 relative to the upper part 5 and on the other hand to have achieved an exact alignment of the lower part 4 to the upper part 5.
• the stop element 502 will come to rest on the upper part 5 at least approximately fitting against the stop rib 49 of the lower part 4 in this position at the same time.
• the closure 1 is in the fully closed position, as shown in FIG.
• the long cams 52 snap in the Region between the two annular beads 47 on the lower part and on the other hand, the cams 70, or optionally the annular bead, pushed under the retaining bead 44 on the jacket wall 40 of the lower part 4.
• the abbess tab 8 must be grasped and the guarantee band 7 torn off. Now the upper part 5 can be rotated, at the same time the now completely separate feed sleeve 6 moves downwards, so that the sealing pin 65 is moved downwards in the outlet sleeve 48. The adhesive can flow upwards through the feed sleeve 6 and flows around the sealing pin 65 to finally exit at the exit opening 59.
• FIG. 5 serves in particular to show the scale 400 which is mounted above the two annular beads 47 on the outside of the jacket wall 40.
• This scale can in principle be designed arbitrarily. In the present example, it is formed as a band of corrugations, which can be seen in the mentioned window 9. The further the shutter is opened, the wider this band becomes. In the fully closed state, the band is no longer visible, but it appears as shown in Figure 1, a digit 0.
• the scale is automatically in the right place, since this scale 400 is mounted by injection molding technology and therefore always the same and in a predetermined Relation to the stop rib 49. This ensures that the number 0 after assembly, in which the fully closed position is reached, the mentioned number 0 also appears at the window 9.
• Such a scale is particularly useful in the use of the adhesives provided here, since these act particularly fast and cheap, when the applied layer is as thin as possible. at the previously known closures of this type with a sealing pin, such a control option was not yet.
• the invention provides a closure 1, which is optimally designed for its use, has excellent sealing properties and also when using a semi-finished product as shown in Figure 4, can be manufactured inexpensively and can be mounted as inexpensively, as previously described is.
