Description

[Detailed Description of the Invention] This invention relates to a sealed container for containing and preserving high-temperature fluid, and particularly to a sealed container that is safe and easy to operate when opened.

B. Prior Art Fluids that do not like to be oxidized by air, such as oil such as tempura oil, are used repeatedly, so it is desirable to store them in a sealed container after use to prevent oxidation. However, in conventional general sealed containers, for example, an inner cover is integrally attached to the inner surface of an opening/closing lid that opens and closes the opening of the container body, and the periphery of the inner cover is attached to the inner peripheral surface of the container body through seal packing. It is tightly sealed. Therefore, when high-temperature oil is stored in a container body, sealed and stored, a negative pressure is created inside the container body as the oil cools, and this causes the inner lid to be firmly attached. Therefore, when reusing or opening the lid,
The inner lid does not open and must be operated with a very strong force, which is very troublesome and requires a strong operating force, making the container unstable to hold, resulting in oil spilling out or the container being damaged when opened. I had a problem when I knocked it down.

(b) Purpose of the invention This invention actively creates a gap in a part of the inner lid that seals the container body when the opening/closing lid is opened to allow air to enter the interior, thereby destroying the negative pressure inside and making it easier to open and close. The purpose is to provide a sealed container whose lid can be opened.

C. Composition of the device In this device, a through hole 31 is opened in the center of the inner lid 13 attached to the inner surface of the fixed lid 12, a seal valve 33 is installed in the through hole 31, and a seal packing 32 is installed around the periphery. Then, attach the center part of the sealing valve 33 of the inner lid 13 to the inner surface of the fixed lid 12 with a screw 34 or the like with an appropriate gap and play,
When the opening/closing lid is fixed, the sealing valve 33 of the inner lid 13 is brought into close contact with the fixed lid 12, and the seal packing 32 is brought into close contact with the inner surface of the container body 1 for sealing. A gap is provided in between, and air is introduced through the gap to destroy the negative pressure inside.
