Reclosable folding box with tamper-evident closure without adhesive
A reclosable folding box of cardboard with at least one tamper-evident closure is provided, which comprises a lid flap with an insertion tab, a cover tab, and a cutout. The tamper-evident closure of the reclosable folding box can be closed by machine without the need for gluing, and the tamper-evident closure can be opened only by destroying the tamper-evident closure. The insertion tab comprises at least one tear-off tab, to which it is connected along one side by at least one first predetermined break line. The tamper-evident closure is set up in such a way that, when the reclosable folding box is opened for the first time, the insertion tab cooperates in the cutout with the cover tab, so that, when the insertion tab moves beyond a breaking point, the at least one tear-off tab tears at least partially along the at least one first predetermined break line. Alternatively, the cover tab comprises at least one second predetermined break line, and the tamper-evident closure is set up in such a way that, when the reclosable folding box is opened for the first time, the insertion tab cooperates in the cutout with the cover tab, so that, when the insertion tab moves beyond a breaking point, the cover tab is torn at least partially along the at least one second predetermined break line.
1. A reclosable folding box of sheet material having an interior with at least one tamper-evident closure comprising a lid flap with an insertion tab, a cover tab hinged to a wide main panel by way of a fold line, and a cutout arranged along the fold line, wherein the tamper-evident closure of the reclosable folding box can be closed by machine without the need for gluing, and wherein the tamper-evident closure can be opened only by destroying the tamper-evident closure,
the insertion tab comprising at least one tear-off tab, to which it is connected along one side by at least one predetermined break line; and
the closure being designed in such a way that, when the reclosable folding box is opened for the first time, the insertion tab cooperates in the cutout with the cover tab so that, when the insertion tab moves past a breaking point, the at least one tear-off tab is torn at least partially along the at least one predetermined break line.
2. The reclosable folding box of claim 1 further comprising two predetermined break lines which are arranged at an angle of approximately 30° to approximately 90°, preferably of 60°, to the fold line.
3. The reclosable folding box of claim 2 wherein the predetermined break lines are formed in sections by perforation or scoring.
4. The reclosable folding box of claim 1 wherein the sheet material of the folding box is a blank of a single piece of material.
5. The reclosable folding box of claim 1 further comprising two predetermined break lines, the two predetermined break lines arranged at an angle of approximately 60° to the fold line.
