摘要 The invention relates to an opening arrangement (1) with a hole (3) provided in the packaging material and covered by an outer strip (4). The strip (4) has an unsealed portion (5) folded over the sealed portion of the strip. Once the package has been filled and finally formed, the package is provided with a thermoplastic structure (6) surrounding the strip (4). The thermoplastic structure (6) consists of two parts, a pouring element (7) and a closure element (9). The closure element (9) is folded over and engages configurationally with the pouring element (7). A heel (10) is placed on the closure element (9) such that it is located flush with the lower surface of the pouring element (7). When the lower surface of the pouring element (7) is provided with the same substance, whereupon the thermoplastic structure (6) is sealed against the package (2). In this instance the surface area 11 of the heel (10) will be sealed to the unsealed portion (5) of the strip (4).
