Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
143 words
A hole plug with a fusible film characterized in that the hole plug includes a bottom wall conically inverted toward the head and provided at its middle with a bulged portion likewise inverted toward the head as well as an annular bead projecting outwardly from the collar in the vicinity of the bottom wall and that the fusible film is an annular disc the inner diameter of which is larger than the outer diameter of the collar, but is smaller than the outer diameter of the annular bead and the outer diameter of the fusible film is larger than that of the head of the hole plug, the head being substantially conical and thereby adapted to resiliently deform upon the expansion of the annular collar so that the head compresses the sealing film while said film fuses to the head and work panels.
