Reclosable Cover for a Hollow Object and Method for Making Same

Abstract

Reclosable cover (100) for a hollow object (200), wherein the cover comprises a base layer (BL), a carrier layer (DL) and an adhesive layer (LL).The base layer has a first base layer cutting line (B1). The carrier layer has a first carrier layer cutting line (D1) at a first distance (d1) from the first base layer cutting line (B1) to provide a first adhesive zone (k1) which is formed to adhere the cover to the hollow object (200).The base layer has a second base layer cutting line (B2) at a second distance (d2) from the first carrier layer cutting line (D1) to form a closing member (SL).The carrier layer has a second carrier layer cutting line (D2) at a third distance (d3) from the second base layer cutting line (B2) to provide a re-adhesive zone (k2) between the second carrier layer cutting line (D2) and the second base layer cutting line (B2).
