Abstract

Cup (1) with an internal wall (2) and an external sleeve (5), the sleeve being formed from a blank (10) of corrugated material comprising a corrugated layer (6) and a Substrate layer (7) and being arranged such that the Substrate layer (7) faces towards the internal wall of the cup. A first end (12) of the blank (10) is overlapped at least partially by a second end (14) of the blank in an overlapping area (19). Further, the sleeve (5) is adhesively attached to the internal wall of the cup (1) at least by a first area (15) of adhesive being provided on an inner side of the sleeve on the first end of the blank and by a second area (17) of adhesive being provided on an inner side of the sleeve on the second end of the blank. The second area (17) of adhesive is provided at a distance from the overlapping edge (13) of the blank, thereby attaching each end of the blank (10) separately to the internal wall of the cup (1).

Claims

1. Cup (1) with an internal wall (2) and an external sleeve (5), the sleeve (5) being formed from a blank (10) of corrugated material comprising a corrugated layer (6) and a substrate layer (7) and being arranged such that the substrate layer (7) faces towards the internal wall (2) of the cup (1), wherein a first end (12) of the blank (10) is in particular overlapped at least partially by a second end (14) of the blank (10) in an overlapping area (19), and wherein the sleeve (5) is adhesively attached to the internal wall (2) at least by a first area (15) of adhesive being provided on an inner side of the sleeve (5) on the first end (12) of the blank (10) and by a second area (17) of adhesive being provided on an inner side of the sleeve (5) on the second end (14) of the blank (10), characterized by the second area (17) of adhesive being provided at a distance (D2) from an edge (13) at the second end (14) of the blank (10).

2. Cup according to claim 1, characterized in that the distance (D2) of the second area (17) of adhesive from the overlapping edge (13) is at least as large as the width (W) of the overlapping area (19).

3. Cup according to any of claims 1 or 2, characterized in that the width (W) of the overlapping area (19) is between 0 and 4 mm.

4. Cup according to claim 3, characterized in that the width (W) of the overlapping area (19) is between 0.5 and 2.5 mm.

5. Cup according to claim 2, characterized in that the distance (D2) of the second area (17) of adhesive from the overlapping edge (13) is between 0.5 mm and 8 mm, preferably between 0.5 mm and 5 mm.

6. Cup according to claim 1, characterized by the overlapping area (19) being free of adhesive between the two overlapping ends (12, 14) of the blank (10).

7. Cup according to claim 6, characterized by the first area (15) of adhesive being provided at a distance (D1) from the corresponding edge (11) of the blank (10).

8. Cup according to claim 7, characterized in that the distance (D1) of the first area (15) of adhesive from the overlapped edge (11) is at least as large as the width (W) of the overlapping area (19).

9. Cup according to claim 8, characterized in that the corrugated layer (6) has wavepeaks (8) spaced apart from the substrate layer (7), these wavepeaks (8) extending in straight lines or in a wavelike pattern or in a zigzag pattern.

10. Cup according to claim 9, characterized in that the distance (d) between adjacent wavepeaks (8) is constant.

11. Cup according to claims 9 or 10, characterized in that the width (W) of the overlapping area (19) is less than three times the average distance (d) between adjacent wavepeaks (8), preferably less than twice the average distance (d) between adjacent wavepeaks (8).

12. Cup according to claims 1 or 2, characterized in that the first area (15) of adhesive and/or the second area (17) of adhesive comprises at least one strip of adhesive.

13. Cup according to claim 12, characterized in that the strip is arranged parallel to the corresponding edge (11, 13) of the blank (10).

14. Cup according to claims 1 or 2, characterized in that the first area (15) of adhesive and/or the second area (17) of adhesive comprises at least one spot (16) of adhesive.

15. Cup according to claim 14, characterized in that several spots (16) of adhesive are arranged on a line parallel to the corresponding edge (11, 13) of the blank (10).

16. Cup according to claim 1, characterized in that at least one additional area (18) of adhesive is provided between the first (15) and the second (17) areas of adhesive.

17. Cup according to claim 16, characterized in that a hot melt glue is provided on the first area (15) of adhesive and/or on the second area (17) of adhesive.

18. Cup according to claim 1, characterized in that cold glue is provided on at least one additional area (18) of adhesive.

19. Cup according to claim 1, characterized in that the sleeve (5) is made from plastic or cardboard material.

20. Cup according to claim 1, characterized in that the internal wall (2) of the cup (1) is provided with de-nesting means (20).

21. Cup according to claim 20, characterized in that the de-nesting means (20) are shaped as at least one projection projecting into the interior of the cup (1).

22. Cup according to claim 21, characterized in that the projection (20) comprises a circumferential projection and/or at least one sectional projection.
