11 ESSELTE PAC AKTIEBOLAG "Tear Opening Means for Containers" ABSTRACT An opening means for containers especially powder proof, liquid proof or gas proof containers of the type which at least at one end is closed by means of an end closure (2) providing an openable end panel (3) which for instance over a sealing edge (4) sealingly engages the container sleeve and in which the end closure is punched through along a line (6) of the end panel (3) extending some distance inside of the sealing edge (4). At the lower surface the end panel (3) carries a sealing foil (12) of a weldable or solderable material which is welded or soldered to the end panel (3) so as to seal the through punching (6) of the end panel (3). The end panel (3) is made of a material having higher shearing strength than that of the material of the lower sealing foil, so that the container can be opened along a sharp line corresponding to the through punching (6) of the end panel (3). For facilitating the opening of the container the end panel (3) may be formed with a tearing tongue or any other means, by which the container can be opened. (For publication figure 4 is recommended)
