Abstract: Base and cover members of a vacuum filter having walls each terminating with an annular bead are sealably joined together by a flexible annular joint. The joint has a median part defining, with an inner flange and a first rounded outer lip, an annular cavity in which the bead of the base member is tightly gripped. A second thinner and more flexible rounded outer lip fits over the bead of the cover member and has a terminal skirt portion which resiliently bears against its wall. The cover member can be removed by outwardly bending the second lip while the joint remains fitted on the base member.

Abstract translation: 真空过滤器的基部和盖部件具有各自以环形凸缘端接的壁，通过柔性环形接头密封地连接在一起。 接头具有中间部件，其中限定了内部凸缘和第一圆形外部唇缘，其中基部构件的凸缘被紧密地夹紧在该环形空腔中。 第二更薄且更柔性的圆形外唇缘装配在盖构件的凸缘上方并且具有弹性地抵靠其壁的端子裙部。 盖构件可以通过向外弯曲第二唇缘而在接头保持安装在基座构件上时被移除。
