A dispenser for dispensing
sheet material includes: a body (1) having four sidewalls (2, 3, 4, 5); a base (6); an opening (7) in the top of the body (1); a cover (8) for covering the opening (7) in use and allowing access to the opening (7) for refilling, wherein the cover (8) has a dispensing opening (9) for dispensing
sheet material from the dispensing opening (9); a platform (10) for supporting multiple sheets of material from below, wherein the platform (10) is movable from a lowermost position when the dispenser is filled with
sheet material to an uppermost position adjacent to the cover (8) when the dispenser is closer to emptying the sheet material; a biasing device (11) for pushing the platform (10) toward the cover (8); and a releasable
locking mechanism for holding the platform (10) in a locked position at the lowermost position, the releasable
locking mechanism including: a first arm (12) movably attached to one of the sidewalls (2, 3, 4, 5). And extending in a direction from the top of the body (1) toward the base (6) of the body (1), wherein the first arm (12) has a top end (13) and a base end (14); a second arm (15), which is movably attached to the base (6) and extends in a direction from the sidewall to which the first arm (12) is attached toward the center of the base (6), wherein the second arm (15) has a sidewall end (16) and a locking end (17), the sidewall end (16) being configured to be connected to the base of the first arm (12). The end (14) engages such that movement of the first arm (12) causes movement of the second arm (15), and the locking end (17) is configured to releasably
interlock with the locking part (18) arranged on the platform (10), thereby holding the platform (10) in the locked position, wherein the cover (8) has a joint (19) on its lower surface, the joint (19) being configured to engage with the top end (13) of the first arm (12) when the cover (8) is closed, thereby releasing the platform (10) from the locked position.
