As a conventional wine dispenser, for example, “Device for Selling Wine by Cup” disclosed in Patent Document 1 which has been previously filed by the present applicant is known. In the device, a wine flow-out tube with a cock communicating with an inner space of an upright cylinder is provided at the bottom of the cylinder, a load lid having an outer circumferential face slidably coming into contact with an inner circumferential face of the cylinder is inserted into the cylinder and an upper end of the cylinder is opened to the atmosphere. The cylinder and the load lid are made of stainless steel. An upper face (bottom wall face of the inner space) of a bottom plate of the cylinder is flat, and a lower end of a butt side opening of the wine flow-out tube is provided at the same height as that of the upper face of the bottom plate of the cylinder so that wine in the cylinder can be entirely discharged.
Wine is poured into the cylinder, and the load lid is inserted into the cylinder with a bottom face of the load lid coming into contact with a surface of the wine. When the cock is opened in this state, the wine in the cylinder is poured into a glass through the wine flow-out tube by weight of the wine and static load of the load lid. Accordingly, the load lid gradually falls in accordance with the dispensing amount of the wine with the outer circumferential face of the load lid coming into contact with the inner circumferential face of the cylinder. Accordingly, during use of the wine dispenser, the wine hardly comes into contact with the atmosphere and can be prevented from oxidizing.
