Abstract: 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.

Abstract: An end plug for a roll of material to be inserted into a retention mechanism, includes: a receiving portion for insertion in the roll, an end face for contacting the mechanism and a bearing member for insertion into the mechanism. The bearing member includes a bearing pin having a counter surface facing the end face and at least one portion for locking the end plug in an end position in the mechanism, the locking portion being positioned within a zone defined by a first surface extending towards the end face from an intersection position 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 extending towards the end face from the intersection position, the second surface being inclined with respect to the axis of the bearing pin by an angle of 141.

Abstract: Dispenser for rolls of material in the form of a web has a withdrawal opening for the material and space for at least two rolls. A first space is arranged adjacent to the withdrawal opening and is intended for a roll in use position, and a second space is intended for a roll in reserve position. A retaining member is arranged so as, in a retaining position, to hold the second roll in reserve position, and to be freed in order to allow the reserve roll to drop down into use position when the first roll is removed. A spindle end arranged in the first space is displaceable in its longitudinal direction and rotatably mounted. It is intended to lie in engagement with the interior of a central core of a roll in use position and is connected to an operating knob arranged outside the housing for feeding out the material web and for drawing the spindle end out of engagement with the central core.

Abstract: Dispenser for rolls of material in the form of a web, such as paper, which dispenser has space for at least two rolls. A first space is intended for a roll in use position, and a second space is intended for a roll in reserve position. A retaining member is arranged so as to hold the second roll in reserve position and to interact with a roll in use position in such a manner that, when a roll is present in use position, the retaining member is held in retaining position, whereas the retaining member is freed in order to allow the reserve roll to drop down into use position when the first roll is removed. The dispenser comprises a wall bracket and a casing. Two support elements are mounted on the wall bracket inside the withdrawal opening and are intended to support a roll arranged in use position. A plate is mounted pivotably on the wall bracket about an axis and is spring-loaded below the axis.
