Title: Method of sealing non-heated favorite drink
Inventor: MARUTA MIKI
IPC: B67C3/02
Filed: 1987-07-15
Abstract: PURPOSE: To ensure the maintenance beverage's quality by sealing a beverage- filled container, filling the upper space in the container with inert gas under a pressure higher than atmospheric pressure, and maintaining the seal condition of a check valve by the pressure of inert gas. CONSTITUTION: This sealing uses a plug type cap 10 having a check valve mechanism in which a valve 3 is placed between a plug 1 and a crown 2, and a spring 7 is placed between the plug 1 and the valve 3. A container 8 is filled with a beverage such as sake or fruit juices such that its level is in a prescribed height from the spout and capped with the cap 10. A case 70 is attached to the container 8, and a high-pressure air is forced from a blowing port 71 to seal a tubular packing 73 to the outside of the spout of the container 8. An inert gas such as nitrogen gas is introduced from blowing port 72. When the inert gas is introduced, the valve 3 is pressed against the spring 7, whereby the inert gas is filled under pressure into the container 8 via an internal opening of the plug 1.  Thus, the space portion above the liquid level of the container 8 is made inert as well as placed in a high pressure. Then, the oxygen and fungi are inactivated, so that the flavor and quality of beverages are not deteriorated.
