Embodiment Construction

[0041] Preferred embodiment

[0042] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0043] Figure 4 Is a cross-sectional view of the check valve of the present invention, Figure 5 for Figure 4 The bottom cross-sectional view of the check valve shown, Image 6 for Figure 4 I-I section view, Figure 7 To show the cross-sectional view of the vacuum container with the check valve of the present invention mounted on the lid, Picture 8 A cross-sectional view of a state where a weak vacuum is achieved by the elastic force of the seal.

[0044] Such as Figure 7 As shown, the vacuum container (100) has a container body (110) and a lid (120) for sealing the opening of the container body (110). A valve mounting portion (121) is formed in the center of the cover (120), and the valve mounting portion (121) is formed as a groove recessed downward, and a through hole-shaped valve is formed in the center of the valve mo...

Abstract

The present invention provides a check valve. In the state where the vacuum display part is sunken, relatively less force is exerted to lift the edge of the main body part of the valve, so it has better airtight sealing ability than the existing ones. The vacuum state can be maintained for a longer period of time without deforming the ring shape. The check valve includes: a main body part of the valve, forming a through hole up and down, formed of elastic material, and has a concave part on the bottom surface, and the concave part provides a space higher than the edge; a vacuum display part, along the upper end of the through hole The inner wall surface of the through hole at the position separated below is integrally connected to the valve main body, and is thinner than the thickness of the valve main body, and protrudes upward, between the cover and the valve main body. When the space between reaches the negative pressure, it sinks toward the cover; and the fixing part, combined with the valve joint part, is used to fix the valve main body to the valve joint part.

Description

Technical field [0001] The present invention relates to an improvement of a check valve and a lid using the same, and more particularly to an improvement of a check valve suitable for use in a vacuum container and a lid for a vacuum container using the same. Background technique [0002] Generally speaking, food with moisture is more prone to spoilage in the air at atmospheric pressure. Generally, food is put in a general food container and stored in the refrigerator, but it is difficult to store the food for a long time only by putting the food in the general food container and storing it in the refrigerator. [0003] In order to store food for a longer period of time, a multi-purpose vacuum container lid is developed. A check valve is installed on the lid and the air inside the container is exhausted to vacuum so that the inside of the container can be kept below atmospheric pressure to store food. [0004] figure 1 In order to show a cross-sectional view of an embodiment of the c...
