[0002] Fresh-keeping boxes, as sealed containers, are widely used in production and daily life. They are typically designed to consist of a box body and a lid, with the lid positioned over the opening of the box body. To ensure the long-term freshness of food, a sealing ring is added between the lid and the box body to achieve a tight seal. However, over long-term use, the sealing ring tends to degrade due to aging, resulting in a weakened sealing effect of the fresh-keeping box, which in turn affects the preservation quality of food. Furthermore, the use of sealing rings to enhance the seal of fresh-keeping boxes increases manufacturing costs and assembly steps. Utility Model Content

[0018] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0019] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A press-type sealed fresh-keeping box includes a box body 1 and a box lid 2. The top opening of the box body 1 faces upward, and a first flange 101 with an opening facing downward is integrally formed at the top outer edge of the box body 1. A plurality of first support plates 102 distributed in a ring array are integrally formed on the inner cavity of the first flange 101.

[0020] A pressing area 201 is formed at the center of the box cover 2, and a second flange 202 with an opening facing downward is integrally formed at the outer edge of the box cover 2. A concave ring portion 203 with an opening facing upward is integrally formed on the box cover 2, and a plurality of second support plates 204 distributed in a circular array are integrally formed on the inner cavity of the concave ring portion 203, and an outwardly protruding snap structure 3 is integrally formed on the inner cavity of the second flange 202.

[0021] When the box cover 2 is buckled on the box body 1, the box cover 2 covers the opening of the box body 1, and pressure is applied to the pressing area 201 to insert the first flange 101 into the opening of the second flange 202 and buckle together through the snap structure 3. The snap structure 3 includes a plurality of outer convex edges 31 distributed in a ring array, and the outer convex edges 31 extend along the circumference of the first flange 101. The bottom surface of the outer convex edge 31 is formed with a guide surface 301 inclined toward the box body 1. Under the guidance of the guide surface 301, the first flange 101 is compressed and deformed to smoothly enter the inner cavity of the second flange 202. A support plate 102 supports the inner cavity of the first flange 101, so that the outer edge of the first flange 101 recovers its deformation and cooperates with the snap structure 3 when entering the inner cavity of the second flange 202, and each second support plate 204 supports the outer wall of the second flange 202. Each first support plate 102 cooperates with each second support plate 204 to maintain the interference fit formed between the inner cavity of the second flange 202 and the outer wall of the first flange 101, so that the sealing box can ensure good sealing even without a sealing ring, and the sealing box has a simple structure, which reduces the manufacturing cost.

[0022] Preferably, the box cover 2 is integrally formed with an annular inner groove 205 , which is coaxially arranged with the second flange 202 . The annular inner groove 205 can enhance the structural strength of the box cover 2 , thereby resisting deformation of the box cover 2 caused by external pressure.

[0023] Preferably, an outer convex ring 103 is integrally formed on the bottom of the box body 1 , and the outer convex ring 103 serves as a support leg to support the box body 1 .

[0024] Preferably, the second flange 202 is integrally formed with two symmetrically arranged lifting ears 206 , so that the user can hold the two lifting ears 206 to drive the box cover 2 to open the box body 1 .

[0025] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
