Abstract
A container for storing and dispensing a liquid has a generally cup-shaped receptacle formed by a circumferential side wall and a front wall. A piston is slidably accommodated within the receptacle. The receptacle and the piston in combination form a chamber in which the liquid is received. The piston forms a sealing structure bearing on an inner surface of the side wall. The inner surface of the side wall has an arithmetic average surface roughness of between 0.05 μm and 4.5 μm R?a.#191 The container allows for air to penetrate in the chamber while it provides for the liquid to be captured therein.
