Abstract: A discharge device including a pump disposed to a container body in which contents are stored and which includes a discharge head provided with a discharge hole formed therein; a mounting cap; a support portion; and a press-down member. By rotating the press-down member, the discharge head is moved downward and the contents are discharged from the discharge hole. The discharge device includes a stopper which is movable between a restricted position where the downward movement of the discharge head is restricted and a non-restricted position where the downward movement of the discharge head is allowed.

Abstract: In the discharger, a stopper is swingable between a restriction position which comes into contact with or approaches a locking target portion to restrict downward movement of a discharge head and a restriction release position where the restriction and locking target portions are separated to allow downward movement of the discharge head by the stopper being swung rearward from the restriction position, the stopper including the restriction portion, a finger hook outward from a depressing member in a left-right direction, and a contact target portion that comes into contact with the depressing member when the stopper is at the restriction position or when the depressing member rotates downward around a rotation axis where the stopper is at the restriction position, and a restraint protrusion protruding downward is formed at a portion of the depressing member rearward of a contact portion with which the contact target portion comes into contact.
