Patent number: 5673825Abstract: A holder includes a casing, a timer-controlled press device, a holding frame, and a locking device. The casing is adapted to keep a deodorant bottle therein and has an opening formed therethrough. The timer-controlled press unit is installed in the casing and can press a spray head of the deodorant bottle at pre-set times to spray out deodorant from the bottle so that the deodorant flows out from the casing through the opening of the casing, thereby spreading fragrance around the casing. The holding frame is mounted slidably within the casing at a normal position and is adapted to carry the bottle thereon. The frame can slide on the casing to an extended position, in which the bottle can be taken out from the frame by hand for replacement. The locking device locks releasably the frame at the normal position within the casing.
