摘要： Can lids made of metal, lacquered on both sides and featuring a pouring outlet covered over with a closure strip having a sealing surface of polyamide, often exhibit inadequate bond strength between the closure strip and the lacquered can lid surface. The bond strength can be increased if the can lid, after the closure strip has been sealed onto it, is heated until the polyamide melts and then the can lid with closure strip is subsequently cooled.

摘要： The process of the present invention allows for the manufacture of lacquered aluminum or tin-plate rings which have the inner edge thereof bent over outwards so that they are suitable for the closures on cans for foodstuffs. A ring blank made of lacquered sheet is pre-shaped by deep drawing to form the curvature needed for bending over the inner cut edge. The final shaping of the pre-shaped blank into a ring for a can lid takes place, after stamping out the opening, by stretching and bending over the cut edge. When a tear-back membrane is sealed on to the bent-over edge, the ring is suitable as an easily opened closure for cans for foodstuffs.
摘要翻译：本发明的方法允许制造具有向内弯曲的内边缘的漆铝或锡板环，使得它们适合于用于食品的罐上的封闭。由漆面板制成的环形坯料通过深冲压预成形，以形成在内切割边缘上弯曲所需的曲率。通过在切割边缘上进行拉伸和弯曲，将预成形坯料最终成形为用于罐盖的环，在冲压出开口之后发生。当撕纸膜被密封在弯曲边缘上时，该环适合作为用于食品罐的容易打开的盖子。

摘要： Lids made of aluminum alloys or ferrous material such as tin plate or tin free steel having at least one stamped out pouring hole and, if desired, at least one hole for air have hot sealed pull-off strips covering the said holes. On the inner side of the lids the region around the holes is pre-treated with an adhesive primer and then coated with a plastisol layer thus providing the cut edges at the holes with protection against attack by the contents of the can.
摘要翻译：由铝合金制成的盖子或诸如锡板或无锡钢的铁质材料，其具有至少一个冲压出口，并且如果需要，至少一个用于空气的孔具有覆盖所述孔的热密封剥离带。在盖的内侧，孔周围的区域用粘合剂底漆预处理，然后涂覆增塑溶胶层，从而在孔处提供切割边缘，防止罐内容物的侵袭。

摘要： The pre-fabricated pouring outlet in a lid for cans containing carbonated drinks lies basically at an angle of 0.degree. or 90.degree. to the rolling direction of the sheet from which the lid is made. The surface of the lid features at least one ring-shaped stiffening groove which points towards the can interior, is concentric with the periphery of the lid and is interrupted in the region of the pouring outlet. The diameter of the groove is 65-80% of that of the nominal diameter of the can.The stiffening groove raises the resistance of the lid towards pressure from inside the can by about 10%. This means that, when manufacturing a lid which has to withstand a specific pressure from inside the can, and using the same material, the thickness of the lid can be reduced to save material.
摘要翻译：包含碳酸饮料的罐的盖子中的预制浇注出口基本上与制造盖的片材的轧制方向成0度或90度的角度。盖的表面具有指向罐内部的至少一个环形加强槽，与盖的周边同心并且在倾倒出口的区域中断。槽的直径为罐的公称直径的65-80％。加强槽将盖的阻力从罐内提高约10％。这意味着当制造必须承受来自罐内的特定压力的盖子并且使用相同的材料时，可以减小盖子的厚度以节省材料。
