Cap for a container
Disclosed is a cap for a container and a container comprising such cap. This container typically accommodates loosely stored, solid products, such as strips, pills, tablets or the like. The cap includes a lid body with a top part and a peripheral wall, wherein the lid body includes a sealing skirt and an inner peripheral wall, which extend from the top part, and form a peripheral groove in between. At least one projection portion for partially covering the peripheral groove is integrally formed with the sealing skirt and the inner peripheral wall.

a lid body with a top part and a peripheral wall,
wherein the lid body comprises a sealing skirt and an inner peripheral wall, which extend from the top part and form a peripheral groove in between,
wherein at least two separate projection portions partially cover the peripheral groove and are integrally formed with the sealing skirt, wherein each projection portion extends from the sealing skirt toward the inner peripheral wall, at an angle of inclination with respect to an extension direction of the sealing skirt, with an interstice being formed between a distal end of the projection portion and the inner peripheral wall so that the projection portion can be released when the cap is removed from a mold, and wherein the cap comprises one integral piece.
2. Cap according to claim 1 , wherein the at least two separate projection portions are arranged on a distal end portion of the sealing skirt.
3. Cap according to claim 1 , wherein the at least two separate projection portions are arranged on a side surface of the sealing skirt.
4. Cap according to claim 1 , wherein the at least two separate projection portions are inclined with respect to an extension direction of at least one of the sealing skirt and inner peripheral wall.
5. Cap according to claim 1 , wherein the cap further comprises a ring-element configured to be connected to a container, wherein the lid body is connected to the ring-element by a hinge.
6. Cap according to claim 5 , wherein the ring-element comprises a tamper-evident ring comprising frangible webs, which are connected to the lid body.
7. Cap according to claim 1 , wherein the cap is manufactured by injection molding of polymer material, wherein the polymer material is selected from the group consisting of PEHD, PEBD and PP.
8. Cap according to claim 1 , wherein the width of each projection portion is 1-5 mm.
9. Cap according to claim 1 , wherein the at least two projection portions are located equidistant to each other in a circumferential direction.
10. Cap according to claim 1 , wherein the inner peripheral wall is provided with a permeable surface so as to form a chamber, wherein the permeable surface is selected from the group consisting of a permeable polymer, a cardboard and a paper sheet.
11. Cap according to claim 10 , wherein the chamber contains an active agent selected from the group consisting of active carbon, silica gel, molecular sieve, clay, other zeolites, and mixtures thereof.
12. Cap according to claim 1 , wherein each projection portion tapers towards its distal end.
13. Container comprising the cap according to claim 1 attached thereto.
14. Cap according to claim 4 , wherein each projection portion is inclined with respect to the extension direction of the sealing skirt or inner peripheral wall by 30-60 degrees.
15. Cap according to claim 1 , comprising from 8-14 projection portions.
16. Cap according to claim 5 , wherein the hinge comprises a film-hinge.
17. A cap for a container, comprising:
a lid body with a top part and a peripheral wall,
wherein the lid body comprises a sealing skirt and an inner peripheral wall, which extend from the top part and form a peripheral groove in between,
wherein at least two separate projection portions partially cover the peripheral groove and are integrally formed with the inner peripheral wall, wherein each projection portion extends from the inner peripheral wall toward the sealing skirt, at an angle of inclination with respect to an extension direction of the inner peripheral wall, with an interstice being formed between a distal end of the projection portion and the sealing skirt so that the projection portion can be released with the cap is removed from a mold, and
wherein the cap comprises one integral piece.
18. Cap according to claim 17 , wherein the cap further comprises a ring-element configured to be connected to a container, wherein the lid body is connected to the ring-element by a hinge.
19. Cap according to claim 17 , wherein each projection portion tapers towards its distal end.
20. Container comprising the cap according to claim 17 attached thereto.
21. Cap according to claim 17 , wherein each projection portion is inclined with respect to the extension direction of the sealing skirt or inner peripheral wall by 30-60 degrees.
22. The cap of claim 1 wherein the at least two separate projection portions are wedge-shaped and exhibit flexibility.
