Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lunch box, especially a lunch box. BACKGROUND

[0002] The lunch box is a kind of container specially used to contain food such as rice and fruits. When going out, people often put food in the lunch box, and when eating, the food can be eaten by opening the lunch box. In modern life, the lunch box has become an essential daily necessity.

[0003] The existing lunch box is designed with multiple containing chambers for storing different foods. A sealing ring is arranged between the cover and the box to prevent food from overflowing from the gap between the cover and the box. However, the existing sealing ring cannot seal each containing chamber, and during use, the food in the adjacent two containing chambers may cause odor mixing.

[0004] For example, a new type of lunch box is disclosed in Chinese patent CN217261856U, which includes a box body, a cover, a sealing ring and a gland. The box body is provided with a containing cavity, and the outer edge of the opening of the containing cavity is provided with a first flange. The cover is fitted at the opening of the containing cavity, and the sealing ring is sealingly fitted at the joint of the box body and the cover. The gland is attached to the upper surface of the cover, and both sides of the gland are provided with deformable elastic arms. The inner side of the elastic arm is provided with at least one buckle point for buckling with the first flange. The utility model sets the gland to press the cover tightly fitted on the box body. The gland only needs two buckles composed of elastic arms and buckle points to realize detachable connection with the box body. The deformation caused by double buckling does not affect the sealing performance of the cover, thereby improving the sealing performance of the double-buckle type lunch box.

[0005] In the above-mentioned patent, the sealing ring is sealingly fitted at the joint of the box body and the cover. The above-mentioned problems exist. UTILITY MODEL CONTENTS
