Wine dispenser

Abstract

An upstanding cylinder and a loading lid are produced respectively from glass. On the upper face of the bottom plate of the cylinder, a substance-pooling concave in which wine lees and tartar are pooled is formed. Owing to this constitution, there is little risk that the external air enters through a gap between the sliding faces of these members into the wine-pooling section in the cylinder and causes the oxidation of the wine. Since the cylinder comprises glass, the wine can be stored under almost the same conditions as in bottles. Further, sanitary precautions can be easily taken. Furthermore, problems such as the sticking of the cylinder to the loading lid due to stainless steel rust and so on can be overcome.

Description

technical field [0001] The present invention relates to a wine dispenser, and in detail relates to a wine dispenser capable of distributing wine to wine glasses by preventing oxidation of wine. Background technique [0002] As a conventional wine dispenser, for example, the "wine by the glass vending machine" of Patent Document 1 filed earlier by the applicant of the present application is known. It is a wine outflow pipe with a valve that is connected to the inner space of the tank at the bottom of the upright tank, and a load cover whose outer peripheral surface slides freely in contact with the inner peripheral surface of the tank is inserted into the tank so that the upper end of the tank is exposed to the atmosphere. open items. The cylinder and load cap are constructed of stainless steel. The top of the bottom plate of the vat (the bottom wall of the interior space) is flat, and the lower end of the root side opening of the wine outflow pipe is set at the same height...

AI Technical Summary

Problems solved by technology

[0007] However, since the cylinder and the load cover are made of stainless steel, the smoothness of the mutual sliding surfaces decreases.

Accordingly, there is a possibility that a small gap is formed between the inner peripheral wall of the cylinder and the outer peripheral wall of the load cap, and the wine may oxidize due to air intrusion.

In addition, the wine in the tank cannot be seen visually.

[0008] In addition, it is known that in the case of austenitic stainless steel, the crystal grain boundary is coarse in the peripheral part (heat-affected zone) of the welded part, and impurities are precipitated at the grain boundary in this part, and composition changes such as transformation to martensite occur. , producing rust

Due to rust, the above gap occurs between the sliding surface of the cylinder and the sliding surface of the load cover, or in the worst case, the cylinder and the load cover are stuck, and the wine cannot be poured into the wine glass.
