Abstract: A dispensing container capable of changing the ratio between the amounts of two kinds of contents to be dispensed, includes two container bodies, two pumps including two stems, an adjusting member configured to press the stems and to be rotatable about an axis extending in a substantially vertical direction, and a pressing head configured to, in response to a depressing operation, rotate about an axis extending in a substantially horizontal direction, to thereby depress the stems via the adjusting member. The adjusting member includes a plurality of pressing portions against which the stems are pressed, and when the adjusting member is rotated about the axis, a depressing stroke of the one of the plurality of pressing portions on the side of one of the stems becomes shorter, and a depressing stroke of the other one of the plurality of pressing portions on the side of the other stem becomes longer.

Abstract: A dispenser can prevent leakage of contents from a nozzle tip when stopping discharging the contents. A dispenser includes: a syringe body that has a filled space of contents, and has a discharge hole at a tip thereof; a plunger that is slid in the syringe body by application of a pushing force, to discharge the contents in the filled space from the discharge hole; and a piston that is formed of an elastic material and located at a tip part of the plunger, wherein a gap is formed between an inner peripheral surface of the syringe body and an outer peripheral surface of the piston, when the plunger is pushed, the piston deforms to narrow the gap, and a back leakage risk (=(gap area/final discharge hole area)) after the deformation of the piston is 0 or more and less than 1.
