摘要： A sealed container comprising a cup and lid and a method for sealing such a container is disclosed. The cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.
摘要翻译： 公开了一种包括杯和盖的密封容器和密封这种容器的方法。 杯子具有沿其长度具有凸起的密封珠的唇缘。 在密封期间，凸起的密封珠被压缩，从而拉伸盖的下部的粘合剂层，并与盖的耐热层形成直接的焊接密封。 密封珠的任一侧的粘合剂形成在盖和唇部的剩余部分之间的粘合密封。 当产品存在于容器的唇缘上时，这种双重密封件特别有效地形成耐用且一致的密封。 焊接的密封件也非常适合于杯子翘曲的情况，或者密封珠沿着其长度的某些部分比沿着其它部分更高。
