Patent ID: 8210384

Claim:
Closure cap for sealing an opening in a base part ( 13 ), with a closure section ( 2 ) and an exterior circumferential marginal web ( 5 ) that extends from the closure section ( 2 ) and that can be inserted into the opening, with a shielding section ( 4 ) that extends from the closure section ( 2 ) and protrudes past the marginal web ( 5 ), and with a hot-melt adhesive ( 11 ) that is arranged adjacent to the shielding section ( 4 ) and is deformable in a plastic manner when heated above a softening temperature, whereby configured on the marginal web ( 5 ) is an abutment arrangement ( 7 ) that grips the base part ( 13 ) when the closure cap ( 1 ) is inserted into the opening, whereby a joint zone having a flexural rigidity that is reduced versus that of the shielding section ( 4 ) is configured between the marginal web ( 5 ) and the shielding section ( 4 ), and whereby a distance between gripping contact areas ( 9 ) of the abutment arrangement ( 7 ) and a bottom side of the hot-melt adhesive ( 11 ), which faces the marginal web ( 5 ), is smaller than a thickness of the base part ( 13 ) in a marginal area ( 14 ) of the opening such that an initial tension is created in the joint zone when the closure cap ( 1 ) is inserted into the opening, wherein present between the shielding section ( 4 ) and the joint zone is a groove-like transition zone ( 12 ), which is filled with hot-melt adhesive ( 11 ) and which is open towards an exterior margin of the shielding section ( 4 ).
