    • Container closures for bottles, cans, tubs, etc. having a sloping or slanted flange on the container which matches a complementary flange on a closure cap. The flange is disposed at an angle of at least 10 degrees and a preferred angle of about 20 degrees for a conventional 63 mm closure and a preferred width of about 0.125 to 0.175 inches. A foil liner carried by the cap includes an induction heat activated adhesive on at least the portion thereof facing the complementary flange on the container for greatly increasing burst, vacuum and drop impact strength of the container because the adhesion is in shear rather than peel. Provision can be made for facilitating peeling of the liner to assist the consumer in opening the container. The liner may additionally be adhered to a horizontal surface of the container for further securing the liner thereto.
    • 在容器上具有与封闭盖上的互补凸缘匹配的倾斜或倾斜凸缘的瓶,罐,桶等的容器封闭件。 对于常规的63mm封闭件,凸缘以至少10度的角度和约20度的优选角度设置,优选的宽度为约0.125至0.175英寸。 由盖承载的箔衬垫包括至少其面向容器上的互补凸缘的部分的感应热活化粘合剂,用于大大增加容器的爆裂,真空和落下冲击强度,因为粘合是剪切而不是剥离的。 可以提供便于剥离衬垫以帮助消费者打开容器。 衬垫还可以附着在容器的水平表面上,以进一步将衬垫固定在其上。
