arranged unequal circumferential length.

The outer surface of the wall 16 of the vessel 13 has an annular groove 20. Above this annular groove 20 is the outer surface the wall 16 with a plurality of slots 21a to 21f provided, which extend in the axial direction from the groove 20 to the mouth of the vessel. As FIG. 5 shows, the circumferential length corresponds of the slots 21a to 21f of the circumferential length of the projections 18a to 18f on the cap 10, the slots being at an angle to one another are arranged and have distances 22a to 22f, which also correspond to the distances 19a to 19f between the projections correspond to the cap 10.

It can be seen that in a certain angular position of the cap to the vessel 13 the cap in the axial direction so on the vessel, can be placed so that their projections 18 pass through the corresponding slots 21 of the vessel. If the The lower edge of the edge part 11 of the cap 10 of the shoulder 15 rests against the vessel, the projections 18 are located inside of the groove 20. The cap 10 is then rotated to any position, thereby allowing the cap to be easily removed from the vessel is prevented.

In order to facilitate the placing of the cap 10 on the vessel 13, the projections 18 are provided with a beveled lower surface formed with which they rest on the edge 24 of the vessel when the cap is not in the correct angular position is put on. The upper edge 25 of the projections 18 is a flat, horizontal surface, whereby it is prevented that the cap 10 can be removed in a similar manner.

Figures 6 and 7 show a modification of the embodiment according to Figure 1 to 5. Thereafter, the wall 16 of the vessel 13 is formed old a second annular slot 26 into the an annular projection 27 is engaged, which is formed on the inner surface at the lower end of the rim portion 11 of the cap 10. As before, the lower surface of the projection 27 is beveled and thereby allows the annular projection 27 through

a simple displacement with the annular groove 26 in engagement is brought. The band portion 11 of the cap 10 is formed with an annular notch or line of weakness 28, and the part of the edge part 11 located below the line 28 is provided with a tongue 29, whereby this part of the edge part can be removed in the manner of a peel-off strip or tape. This after Jig. 6 and 7 modified embodiment thereby represents a theft-proof vessel in which the removal of the edge portion below the line 28 is unjustified Removal of the cap indicates.

In Pig. 8 and 9 shows a vessel with a closure cap, in which there is an even stronger protection against access to the vessel.

As before, the cap 30 has a depending rim portion 31 » which is provided along its inner circumference with a plurality of spaced apart projections 32, which - as before - have unequal circumferential lengths and are arranged at unequal distances from one another.

On the outer wall 34 of the vessel 35 are corresponding Slits 33 are provided which are formed by means of a plurality of projections 36 arranged at a distance from one another, which are formed on the wall of the vessel and extend outward.

According to Pig. 8, the cap 30 is opened by a movement in FIG axial direction brought into engagement with the vessel 35, so that in the correct angular position, the projections 32 in the corresponding Engage slots 33 on the vessel wall and pass through them. Thereafter, the cap 30 is in any position twisted to the vessel.

Greater security of the vascular occlusion is achieved by that the vessel is provided with a second plague position device in the form of a ring 37 which is on the vessel is arranged and is independently rotatable against this about the vessel axis. The ring can go through a shoulder or a

Ridge 38 to be secured on the vessel against axial movement, and the upper edge of the Peststellringes is circumferential Projections 39 shown, which the projections 36 on the vessel in correspond to the manner that they form similar spaces or slots 40.

In order to place the closure cap 30 on the vessel, the projections 36 and 39 must therefore be rotated correctly of the locking ring 37 are arranged in alignment. After the cap 30 has been put on, it is in any position rotated, then the locking ring 37 is rotated relative to the cap and the vessel in any position, so that a higher locking security is effected.

To make it easier to remove the cap, code symbols or other display features can be found on the cap, the vessel and the plague collar be attached.

Pig. 10 to 12 show a simplified embodiment in which both the vessel and the cap are easily cast in the casting process can be produced. The vessel 4f has inclined side walls 42 and the slots 43a to 43f are as can be seen more clearly from Pig. 12 results, formed in a puddle 44, which extends from the upper edge or the mouth of the The vessel extends outward in such a way that the corresponding projections 45a to 45f are received therein, which are formed along the inner surface on the periphery of the edge portion 46 of the cap 47.

A fourth embodiment of the invention is shown in Pig * 13 bis and explains the application of the invention to a vessel with a screw cap at the top. The vessel is made from a bottle 50, the neck 51 of which is provided with a conventional screw thread 52. The bottle neck 51 is on its upper edge with an outwardly protruding splash which, as in the previous exemplary embodiment, has slots which define the spaces 54. The cap 55 possesses an edge portion 56, the inner surface of which has a plurality of voa inwardly extending and spaced from one another
