阅读:694发布:2022-03-02

专利汇可以提供CONTAINER SELF-SEALING CLOSING PROCESS专利检索,专利查询,专利分析的服务。并且By covering humidity-sensitive meltable masses with an insertion that consists of a thermally stable and water vapour-tight plastic foil (1) and of a plastic disk (2) made of a thermoplastic material with a linear coefficient of expansion of at least 6.10-5/K, the surface of said meltable masses (6) may be self-sealingly closed. The meltable mass is reliably protected by this self-sealing closure against the penetration of humidity, even after a long storage. Thus closed containers with humidity-sensitive meltable masses may thus be stored for a long time.,下面是CONTAINER SELF-SEALING CLOSING PROCESS专利的具体信息内容。
