Far neck casing with a removable cover and the tensioning element

摘要

The wide necked container has a removable lid and tensioning element, which has outwardly projecting lugs on its top edge. These lie in one plane and are separated by interspaces. The lid has a downwards bent edge, split into segments whose width corresponds to the width of the interspaces. The segments have radially outwardly pointing beads which hold the tensioning element. On their underside, at a distance from the container wall (6), the lugs (4) have downwardly pointing projections (7). The beads (9) have radial slots (10) to guide a tension element (3). Close to the lid edges (12) the slots have recesses (13), which when the lid is on, form a groove with the lug projections to accept the tension element. At the end away from the lid edge, the bead has holding elements to hold the tension element in its "open" position.
