ABSTRACT:
The basic bubble cap assembly for sealing a hole in a tray deck for example, comprises an inner tubular sleeve having a lower flanged end telescopic with the inner surface of a tubular riser having a lower flanged end, and gasket means for sealing the lower flanged ends of both the telescopic tubular riser and the inner tubular sleeve to the upper and lower peripheral surfaces around the hole for providing a double seal between the tray deck and the bubble cap assembly, for minimizing leakage, and for assuring proper alignment of the bubble cap assembly relative to the tray deck. Three modifications are disclosed. One comprises a spider secured on the lower end of the hold-down stud for placing it in tension for compressing the two sealing gasket means. A second embodiment comprises a hold-down stud lower end fastened to a cross bar which is welded to the internal surfaces of the inner tubular sleeve. The third embodiment includes an inner tubular sleeve having two horizontal cuts on opposite cylindrical sides of the upper portion thereof extending horizontally for a substantial distance for forming two kidney shaped inwardly bent portions contiguous with the hold-down stud to which it is welded.
