Description

  The present invention relates to a bottled liquid quality maintaining device that can be attached to an opening of a bottle filled with a beverage liquid such as wine or sake, and can maintain the quality of the beverage liquid over a long period of time after opening, and equipped with the same Related to the heat insulation device.

  In general, brewed liquors such as wine and sake are said to have a faster quality deterioration related to taste and aroma due to oxidation, etc. compared to distilled liquors. Avoid contact with air and avoid problems such as nitrogen gas and argon. It is widely known that a method of storing in an active gas environment (for example, see Patent Document 1) is effective. Therefore, some of these beverage liquids supplied mainly in bottles deteriorate in quality by replacing the air inside the bottles with nitrogen gas or inert gas at the time of filling, or filling the liquid under vacuum. The processing method which prevents this is in practical use.

  However, the above processing method is effective in the distribution process until the bottle is delivered from the beverage liquid manufacturer to the end consumer, but it is not effective for storage after the bottle is opened once. There was a problem. That is, since it cannot be filled again with nitrogen gas or inert gas, or cannot be evacuated by sucking air, deterioration due to contact with air cannot be avoided. Also, some wines are not filled with nitrogen gas or inert gas at the time of filling, or are not vacuumed. Especially for expensive wines, take time slowly in small portions. There was no way to satisfy consumers' desire to taste.

  On the other hand, a liquor server that supplies small amounts of liquor in a bottle has also been proposed (see, for example, Patent Documents 2 and 3). However, this type of server is equipped with a cooling device and heating device for supplying liquor at an appropriate temperature, an electromagnetic pump for dispensing beverage liquid, and a gas cylinder for each bottle. There are problems that the installation of the bottle and the movement of the apparatus (that is, the carrying of the bottle) are inconvenient and the production cost is high.

  Therefore, if you want to drink a small amount of the liquid for drinking in multiple bottles at home, etc., you must replace the bottles each time, except for purchasing multiple servers, and the work is complicated. Or there was a problem that contact between the liquid for drinking and air was unavoidable when replacing.

  By the way, in recent years, small gas cylinders have become easily available, and it has become possible for consumers to fill nitrogen gas and inert gas at home.
