End plug for a roll of material, roll of material and retention mechanism in a dispenser
摘要：
An end plug for a roll of material to be inserted into a retention mechanism, includes a receiving portion to fit into a hollow core of the roll of material; and a bearing member to fit into the retention mechanism. The bearing member includes a bearing pin having a counter surface facing the receiving portion; and a locking surface for locking the end plug in an end position in the retention mechanism, the locking surface being arranged between the receiving portion and the bearing pin, the locking surface having at least one portion inclined with respect to the longitudinal axis of the bearing pin by an angle to the longitudinal axis of the bearing pin in the range of 117° to 141°. A retention mechanism in a dispenser for retaining the end plug of an exchangeable roll of material is also disclosed.
