Double-cover buckled-type plastic preservation box

Abstract

The invention relates to a double-cover buckled-type plastic preservation box which comprises a box body and a box cover, an outward flanging is arranged at the opening part of the box body, the box cover is provided with a seal groove, a seal strip is arranged in the seal groove, the seal strip and the opening part of the box body are mutually matched in a sealing way, and a rib is arranged under the box cover and provided with a fastener which is in contact with the lower edge of the flanging of the box body. The double-cover buckled-type plastic preservation box is characterized in that: a cover sleeve is arranged outside the box cover, and the inner wall of the periphery of the cover sleeve is in inward force fit with the rib of the box cover. The double-cover buckled-type plastic preservation box has the major characteristics that: the cover sleeve is arranged outside the box cover; when the plastic preservation box is used, the box cover covers the box body so that the seal strip of the box cover and the opening part of the box body are sealed, the fastener of the rib of the box cover is buckled at the lower edge of the flanging of the box body, and then the cover sleeve is covered; and because the inner wall of the periphery of the cover sleeve internally presses the rib of the box cover, the fastener in the rib cannot slip off by self after grasping the lower edge of the flanging of the box body, therefore, the connection reliability of the box cover and the box body is greatly improved, and the sealing effect is ensured.

Description

technical field [0001] The invention relates to a plastic fresh-keeping box, in particular to a double-cover press-button plastic fresh-keeping box, which belongs to daily necessities. Background technique [0002] The plastic fresh-keeping box has a good sealing effect. Put the food in the fresh-keeping box, cover the sealed box cover, and then put the fresh-keeping box in the cold box, so that there will be no odor and achieve the purpose of fresh-keeping; in addition, due to the sealing of the fresh-keeping box, some Dry food is placed in the box, which can avoid moisture for a certain period of time. It can be seen that the sealing structure of the fresh-keeping box and how to maintain the tight fit of the sealing structure are very important. The main structure of the plastic fresh-keeping box includes a box body and a box cover. A sealing groove is formed at the lower mouth of the box cover, and a sealing strip is installed in the sealing groove. The sealing strip and ...

Problems solved by technology

However, although the pulling flaps of the existing fresh-keeping boxes have many structures, there are two main disadvantages. One is that the flaps are integrated with the lid and extend from the edge and pass through the buckle of the bendable part. , plus repeated bending, the service life is limited, which will cause breakage and loss of sealing; second, the buckle in the flap of the box cover and the card on the outer wall of the box are easy to slip off by itself, and the fastening effect is poor, which affects the sealing performance
