Covering cap for closing an opening comprises a screening section protruding over an edge bar and a melt adhesive arranged in the region of the screening section and plastically deformable on heating above a softening temperature

摘要

Covering cap comprises a screening section (4) protruding over an edge bar (5) and a melt adhesive (11) arranged in the region of the screening section and plastically deformable on heating above a softening temperature. A number of abutment elements (7) are formed on the edge bar to interact with a base part (13) when the cap is joined to an opening. A hinged region (3) having a lower bendability than the screening section is formed between the edge bar and the screening section. Preferred Features: The hinged region has a groove section having a material strength which is less than regions on the inner side. A groove-like transition section (12) filled with melt adhesive is formed between the screening section and the hinged region and opens in the direction of the outer edge of the screening section.
