WIPO Patent Application WO/2003/013976

A1

The invention relates to a reclosable container (V) comprising an edge (R) and a multilayer foil (F) covering the opening (O) of the container and the edge (R), wherein the multilayer foil (F) consists of at least one outer layer (1), a sealing layer (2) facing the edge (R) and an adhesive layer (3) placed between the outer layer (1) and the sealing layer (2), wherein said sealing layer (2) is fixed along said edge (R) and is embrittled to form a tearing point (W). The embrittlement is achieved by means of a sealing tool (S), wherein the width (L) of the tearing point (W) has a double-padded form. The sealing tool (S) for producing the reclosable container (V) is configured with partial sealing surfaces (SF). According to the invention, the reclosable container is characterized by high closing safety even at low temperatures and under the influence of humidity. The double-padded embodiment enhances the stability of the reclosable seal and provides a more perfect fit.
