PROBLEM TO BE SOLVED: To provide a composition dispensing apparatus which is not limited by rheology of a composition, a size of a dose, orientation of use, or the amount of pressure applied.SOLUTION: A composition dispensing apparatus comprises: a compressible container; a unit dose delivery system including an entry element and an exit element that are mechanically connected with each other, side walls, and a dosage chamber; and a dispensing aperture. A liner movement ratio of the exit element to the entry element is approximately less than 1. When a pressure is applied to the compressible container, both of the entry element and the exit element effectively form seals by making contact with the side walls, and a dosage of a composition is established in the dosage chamber. The composition is dispensed through the dispensing aperture when the exit element is released from the side walls. |
