DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0053] A blank for a cylindrical pack is denoted by 1 in FIG. 1. A base 2 and a lid 3 are provided in addition to this casing 1. A removal opening 4 is arranged eccentrically in the lid 3.

[0054] The base 2, just like the lid 3, is crimped to the casing 1. It is also conceivable for the base 2 and/or lid 3 to comprise the casing or be inserted thereinto. Apart from crimping, it is also conceivable for the base 2 and/or lid 3 to be glued in, sealed or fastened in another way.

[0055] In this embodiment the casing 1 is flanged with respect to the lid 3 onto this. The flanging 5 thus projects somewhat into the lid area 3.

[0056] An outer closure disc 6 is arranged on the lid 3. This closure disc 6 has a cut-out 7 corresponding with the removal opening 4. A fold-line 8 intersecting the closure lid 6 is provided opposite the cut-out 7. The contour of the closure disc 6 is formed to be curved in this region. The curved contour 9 can in that case be defined by a weakening line 10, in which case the region 11 separated by the weakening line 10 is glued to the lid 3.

[0057] Provided at the center point of the closure disc 6 is a rotary bearing 12 which in this embodiment is executed as a plastics material rivet. Other embodiments of paper or metal are conceivable.

[0058] The rotary bearing 12 in turn is also mounted in the lid 3.

[0059] For first opening, the weakening line 10 is now broken open and the curved contour 9 folded upwardly. A hand grip results, by which the closure disc 6 can be turned so that the cut-out 7 and the removal opening 4 are brought into coincidence.

[0060] Due to the inwardly projecting flanging 5 the closure disc 6 has to be formed to be slightly smaller than the lid 3.

[0061] In order to achieve improved sealing of the removal opening a second closure disc 16, which is similarly provided with a corresponding cut-out 7 and is arranged below the lid 3, is provided. The closure disc 6 and the closure disc 16 are connected together by way of the rotary bearing 12 to be secure against relative rotation.

[0062] The closure disc 16 is entrained when the closure disc 6 is rotated.

[0063] Due to the flanging arranged only at the outside the closure disc 16 can be formed with exactly the same size diameter as the lid 3, thus completely covers this.

[0064] The cut-out 17 can also be formed as a sieve or the like so that a sprinkler is formed.

[0065] It is also conceivable for a plurality of cut-outs 7 and 17 to be provided, in which case the cut-outs 17 can then be of different construction and thus make possible different functions in the removal of content.

[0066] In this connection it is also conceivable for the closure discs 6 and 16 to be glued or sealed to one another in the center. The lid 3 then has in this region an appropriate cut-out through which the glueing takes place.

[0067] The pack can be constructed to be stackable, i.e. the base is provided with, for example, an edge capable of engaging in a corresponding shaping of the lid.

[0068] Alternatives to the afore-described integrity closures are also conceivable. Thus, for example, the closure disc 6 can be glued at a point to the lid and at the time of first opening this glueing has to be broken. Securing by adhesive strips or the like is also conceivable. Equally, it is conceivable for a perforation 10 to have to be broken open in order to create rotatability. Here, for example, the edge of the uppermost layer 6 of the opening mechanism can be connected with the pack by way of a perforation 10 or other weakening line.

[0069] In that case it is also conceivable for the removal opening 4 of the lid 3 to be closed and for the material present there to have to be removed by separation in order to create a removal opening. For that purpose, one of the layers of the opening mechanism can be connected with this material part. The removal opening is created at the time of first opening.

[0070] It is also conceivable for a label or other covering 20 of paper, cardboard or the like to be arranged above the opening mechanism and fastened there by glueing, sealing or clipping. This then has to be first removed. This covering 20 can, for example, be glued or sealed onto a projecting edge of the pack casing.

[0071] Moreover, it is conceivable that in the uppermost layer 6 of the opening mechanism the removal opening therein is closed and has to be first created by separation of a material part 21.

[0072] The removal openings 7 and 17 can have the most diverse shapes.

[0073] Although only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
