The invention relates to a drip-proof inset of the type that comprises a bottom and a J-shaped border surrounding the same, which border is composed of two side pieces and one back piece. Initially, said inset is in the shape of a plane sheet (A) that includes a number of scorings, viz, two first scorings (8), along which two side pieces (3') can be turned up at an angle to a bottom-forming part (1') of the sheet, a sec- ond scoring (9), along which a back piece (4') can be turned up at an angle to the bottom sheet part (1'), as well as at least one additional, third scoring (11) that extends halfway between two opposite edges (7) of the sheet in order to, before turn- ing-up of said back and side pieces, enable folding of the sheet in the middle during formation of two folded-up sheet halves having a halved surface area. |
