TIN CAN LID FOR OUT-OF-ROUND CANS, IN PARTICULAR CANS OF OBLONG SHAPE IN HANSA FORMAT |
摘要 |
<p>: There is provided a tin lid for use with cans of oblong shape in Hansa format, which includes in its lid image section a tear-open portion defined by a self-contained recessed line capable of being broken up at one end of the lid by means of a pull-open ring attached to this end. At the other end, said recessed line includes a straight recessed line portion which extends in chordal-type fashion with respect to the core wall shaped like an arc of a circle and which is positioned perpendicular and symmetrically to the longitudinal lid center line and is further connected with the other recessed line components through an also chordal-type or polygonal recessed line connecting portion. This tear-open portion area defined by the polygonal arrangement of the recessed line, above all, is stiffened by a group of like and completely uniformly distributed beads, which are further associated with the chordal-type recessed line portion in predetermined manner, to so ensure the tear-open portion's final separation from the remaining lid section virtually without any remarkable capacity of the lid image section to undergo spring movement itself.</p> |
