ABSTRACT The cover lock for plastic, blow-moulded, wide-neck casks (2) uses a solid lock plastic lock ring (9) that is in the form of a collar that lies against a solid band (10) that projects radially outwards from the cask wall beneath the cask opening, and a counter ring (11) that is similarly manufactured from plastic that lies on a flange (12) that is formed at the bottom of the outer edge (4) of the cover. Lock sleeves (13, 14) are formed on the lock rings (9, 11) and spaced around the periphery and these fit into corresponding drilled holes (15, 16) in the band (10) of the cask and in the cover flange (12). The lock rings (9, 11) and the lock sleeves (13, 14) that are formed on these incorporate continuous conical drilled holes (17, 18). In order to lock the cover (1) that is installed on the wide-neck cask (2) clamp pins (19) that are of plastic are pressed into the conical drilled holes (18, 17) that are aligned in the two lock rings (11, 9), this being done by means of a press tool, when the lock ring (9) that lies against the cask band (10) is supported by an appropriate device. The clamping force that is exerted by the clamping pins (19) presses the cover seal (8) against the edge of the opening in the neck (3) of the cask. (Figure 1)
