End plug for a roll of material, roll of material and retention mechanism in a dispenser

摘要

The invention relates to an end plug (5) for a roll of material to be inserted into a retention mechanism (1), the end plug comprising: a receiving portion (60) for being inserted in the roll of material, an end face (680) for contacting the retention mechanism and a bearing member (70) for being inserted into the retention mechanism. The bearing member comprises a bearing pin (80) comprising a counter surface (82) facing the end face and at least one locking portion (950) for locking the end plug in an end position (250) in the retention mechanism, the locking portion being positioned within a zone (900) defined by a first surface (90') extending towards the end face from an intersection position (910) with the bearing pin, the first surface being inclined with respect to the longitudinal axis of the bearing pin by an angle of 117 and a second surface (90'') extending towards the end face from the intersection position, the second surface being inclined with respect to the longitudinal axis of the bearing pin by an angle of
