摘要 PCT No. PCT/EP97/02352 Sec. 371 Date Nov. 9, 1998 Sec. 102(e) Date Nov. 9, 1998 PCT Filed May 9, 1997 PCT Pub. No. WO97/43185 PCT Pub. Date Nov. 20, 1997The invention relates to a lid for tins, cans and the like, which lid is made of a layer of sheet metal or plastic that is attached to the wall (3) of the container by means of a seam-folded or other type of joint. The lid has a groove (5) in which the tip of a spoon or other suitable utensil can be inserted so that the latter can act as a lever therein and open the lid by tearing the material along a first line of weakness (6) located on the bottom of the groove (5). The lid advantageously has a second line of weakness (7) that is located in the area where the cross section of the groove (5), which is essentially U-shaped, joins the central portion of the lid; this second line of weakness contributes to weakening the lid material locally, in the above mentioned area, thereby enhancing the leverage exerted in order to open the lid.
