Abstract

PURPOSE: To obtain an airtight container inside which air can be replaced with nitrogen gas so that it can be used for preserving foods over a long period of time, by a method wherein a first sealing member is provided to make the container airtight and equipped with a nitrogen gas inlet port and an air outlet port and second sealing members are respectively provided on the ports. CONSTITUTION: An A sealing member 1 is provided on a container 4 to make the container 4 airtight and equipped with a nitrogen feed port 2 to feed nitrogen gas and an air outlet port 3 to vent air. In addition, B sealing members 5 are respectively provided on the nitrogen feed and air outlet ports 2 and 3 to block the ports 2 and 3. When the container 4 is used, foods are put in the container 4, and nitrogen gas is fed from the nitrogen feed port 2 of the A sealing member 1. Thus. the inside of the container 4 is filled with nitrogen gas and air inside the container 4 is vented from the air outlet port 3. Thereby, as food can be prevented from being oxidized by oxygen and from being spoilt, a long term food preservation becomes feasible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention injects nitrogen gas into a container to replace air with nitrogen gas. Therefore, the present invention relates to an airtight container which is useful for long-term storage because it prevents the oxidation and spoilage of foods because air is lost and oxygen is blocked.

[0002]

2. Description of the Related Art Conventionally, there has been a container with a lid.

[0003]

However, this has the following drawbacks. Although it was a container with a lid, the air in the container could not be replaced with another gas. The present invention has been made to solve these drawbacks.

[0004]

[Means for Solving the Problems] A container (4) is provided with an A sealing body (1) for hermetically sealing, a nitrogen inlet (2) and an air exhaust port (3) are provided therein, and a B sealing is provided for each. Provide the body (5).

[0005]

The nitrogen gas is injected into the container (4) through the nitrogen injection port (2) and the air is exhausted through the air exhaust port (3) to replace the nitrogen gas with the air.

[0006]

Embodiments of the present invention will be described below. (A) The container (4) is provided with the A-sealing body (1) for sealing. (B) The A sealing body (1) is provided with a nitrogen inlet (2) for injecting nitrogen gas and an air exhaust port (3) for exhausting air. (C) The nitrogen inlet (2) and the air outlet (3) are each provided with a B sealing body (5) for sealing. The present invention has the above-described configuration, and when this is used, food or the like is put in the container (4) and nitrogen gas is injected from the nitrogen injection port (2) of the A sealing body (1). Then, the container (4) is filled with nitrogen gas. Therefore, the air in the container (4) is exhausted from the air exhaust port (3), and the oxidation and spoilage of food and the like due to oxygen can be prevented, so that the food can be stored for a long period of time.

[0007]

As for the effect of the embodiment, by filling the container with nitrogen, it is possible to prevent the oxidation and spoilage of food and the like due to oxygen, so that it can be stored for a long time.
