    摘要： An article is disclosed comprising a lid engaged to a container by the formation of interlocking waves of lid material and container material at the junction of the lid and container. The interlocking waves are geometrically aligned relative to the interior of the container so as to maximize the burst strength of the container, and also to minimize the force required to peel the lid from the container. An unheated clamp head is used to clamp the lid structure immediately adjacent a heated seal head, the heated seal head being used to form the interlocking wave structure around the inside rim of the container. The clamp head prevents any melted portions of the container or lid from flowing to or towards the outside rim of the container, and thereby prevents the formation of similar interlocking waves about the outside rim of the container. Elimination of the interlocking waves about the outside rim of the container yields a clamped-wave seal structure having reduced peel initiation forces and reduced average peel forces, without affecting the resistance of the container/lid system to high burst pressures typically encountered under retort conditions.

    摘要： A unique selectively openable seal line made between two sheets of flexible thermoplastic material is disclosed, the seal line being exceptionally resistant to unintentional opening forces but being easy to open upon the application of a specific force. The seal line may be employed in various containers, including a two chamber container for the separate storage and selective mixing of two medical substances. The container includes two sheets forming the exterior of the container and an inner, diaphgram sheet between the outer sheets. The selectively openable seal line is disposed between one of the outer sheets and the diaphragm sheet. Preferably a permanent line of securement is also included, between the other exterior sheet and the inner diaphragm sheet, extending substantially parallel to and coextensive with the openable seal line. Such a container provides a relatively inexpensive and reliable means for separately storing two medical substances in a closed system under sterile conditions, while still providing for quick and easy selective mixing of the substances when desired. Finally, the present invention is also directed to a sealing die for making the unique seal line and to a method for manufacturing the container.
