As shown in Figure 1, the cap 1 has a cylindrical recess 7, which in the region of the lid surface 6 with respect to the axis A of the closure lid 1 arranged is. In it two webs are arranged, which on the side wall 10 and are arranged on the bottom 11 of the recess. For the security the function of serving as coupling elements 8 Webs 12 is to provide at least one web. The number of as Coupling elements 8 serving webs 12 but depending on the purpose vary.

FIG. 2 shows an associated screw-on head 14 for screwing on of the closure lid 1 on a tube. The screw-on 14th is also cylindrical like the recess 7 shown in FIG formed, wherein the diameter of the cylindrical Aufschraubkopfes 14 corresponds to that of the recess 7. Of the Aufschraubkopf 14 has a recess 16 in the form of a Slot, whereby the Aufschraubkopf 14 form-fitting with the Closure lid 1 can be connected. This is the Aufschraubkopf 14 in the direction of the axis against the cover surface. 6 pushed and inserted into the recess 7 of the closure lid 1, whereby a positive connection between Aufschraubkopf 14 and Closure lid 1 is created. The Aufschraubkopf 14 of Aufschraubwerkzeugs is rotatable about the axis A and is over the Drive-on tool driven. The torque is over the slit-shaped recess 16 on the webs 12 of the Verschlussdekkels transferred, whereby the cap 1 on a neck a tube is screwed on.

Another closure lid 1 according to the invention is shown in FIG 3 shown. On the cover surface 6 of the closure lid 1 is an elongated elevation 17, which serves as a coupling element 8 serves shown. The elevation 17 is rectangular in cross section trained, but it can also have other shapes. Instead of a single, elongated elevation 17 as a coupling element 8 can also be several centric on the lid surface 6 distributed surveys 17 may be arranged. These Elevations can, for example, star or radial be.

As can be seen from Figure 4a, the recess 7 in plan not be circular. The recess 7 can also be used as a polygon, as shown in Figure 4a, be formed as a square. Also other polygons are conceivable, for example, the depression 7 have the shape of an octahedron. Due to the special geometry and shape of the recess 7 is a particularly simple embodiment the Aufschraubkopfes 14 possible. Such is the case in Figure 4b shown screwing 14 a square body, which similar to a stamp fit into the recess 7 according to FIG 4a can be introduced. Only by the shape and geometry of the depression 7 and the Aufschraubkopfes 14 is a rotation lock for the screwing is ensured. The attachment of additional wells and / or elevations on the closure lid or on the Aufschraubkopf 14 fall away with it.

Figures 5 to 8 show a further embodiment of a Closure cover 1. In FIG. 5, a closure lid 1 is provided shown, which is screwed onto a tube 2. The cap 1 has a tear-off ring 18 and is farther grooved. The grooves 19 are elongate. How out As shown in FIG. 6, the closure lid 1 is slightly conical. The tear-off 18 is on the side facing the tube on Closure lid 1 attached. As Figure 7 shows are in this Embodiment five webs evenly distributed over the circumference attached to the bottom 11 and to the side wall 10 of the recess 7. The arrangement with the five webs 12 ensures a optimal power transmission in relation to the production cost for a closure lid 1. The thickness of the webs 12 is preferably 1mm to 2mm. Depending on the size of the tube or the Cover 1 may be up to 5mm or more in thickness. Even narrower bridges are vorstellbr. It is also conceivable that a different number of webs 12 may be present. For example, an arrangement with three evenly distributed Stegen showed good results. As can be seen from FIG. 8, is the web 12 each with the side wall 10 and the bottom 11th the recess 7 of the closure lid 1, advantageously einstükkig, connected. This allows optimal power transmission in a rotational movement of the positively engaging Aufschraubkopfes 14. The web 12 is approximately triangular in its cross section educated. Preferred forms can also be rectangles or Be Trapeze. However, other forms are also conceivable. The recess 7 is apparently not cylindrical, but slightly conical and corresponds approximately to the shape a truncated cone. The inclination angle of the side surface 10 of Recess 7 is preferably 5 ° to 10 °, larger angles of inclination are also conceivable depending on the individual purpose.

The Aufschraubkopf 14 is as Figure 8 shows, in the recess. 7 of the closure lid 1 can be inserted in a form-fitting manner. The screw-on head 14 is generally rotationally symmetrical. The basic shape of Aufschraubkopfes 14 corresponds or corresponds with the shape of the recess 7. In the present case is the Aufschraubkopf 14 so basically designed as a truncated cone. But it is also conceivable that based on the basic form no positive connection between the Aufschraubkopf 14 and the Well 7 must be present as long as a positive connection between the actual coupling elements 8 and 15 is present. The screw-on head 14 has recesses 16, which fit in the respective webs 12 of the closure lid 1 approximately accurately can be introduced. Like the screw-on head 14 according to FIG. 8 shows, the recesses 16 do not have in the side view necessarily the same shape as the webs 12 of the closure cap 1 have. An elongated slot is sufficient.

It is also conceivable that the connection between cap 1 and Aufschraubkopf 14 next to a positive connection also can have a frictional engagement. This can be, for example be achieved in that the width of the slots of the wells 16 slightly smaller than the width of the webs 12 selected become. This ensures that when inserting the Aufschraubkopfes 14 on a cap 1 next to a rotation lock also a fuse in the longitudinal direction or axial direction A is present. Thus, the handling of a simplified Closure lid 1. Because this allows the cap 1 positioned with the same tool on the outlet nozzle of a tube be screwed in and then. An additional Apparatus which positions the closure lid 1 on the tube, is therefore unnecessary.

FIGS. 9 to 11 show various arrangements of slit-like depressions for a five-part cap 1 according to the embodiment of Figures 5 to 8. The FIG. 9 shows a view from below of a screw-on head 14, in which the slots according to the arrangement according to FIG 7 are arranged. The screw-on 9 is, for example made of metallic material or plastic. FIG. 9 shows a in its cross section full Aufschraubkopf 14, but it is also conceivable that this is tubular.

In FIG. 10, the recesses 16 are in the form of slots designed through continuous slots. This has the advantage on the one hand that the depressions 16 comparatively simple, for example by milling or another machining method can be applied in the Aufschraubkopf 14 and on the other hand There are options for suitable insertion of the screw-on head 14 via its slots on the webs 12 of a closure lid 1.

Although FIG. 11 shows the same arrangement as an alternative to FIG depressions, but not as continuous slots designed Depressions 16.
