Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, and more specifically, to a fresh-keeping box lid. Background Art
[0002] With the acceleration of the modern life rhythm, people's demand for food preservation and storage is increasing day by day. As an indispensable daily necessity in daily life, the fresh-keeping box is mainly used for food storage and preservation. Through a sealing design, it prevents food from contacting the external air, thereby slowing down the oxidation and deterioration process of food; therefore, its performance and use experience have become the focus of consumers' attention.
[0003] The locking mechanism between the lid and the box body is the key to ensuring the food preservation effect and sealing performance; most traditional fresh-keeping box lids rely on the snap structures arranged on the edges to achieve the sealing and locking of the lunch box. When opening, all the snaps need to be opened before the lid can be opened, and the opening process is cumbersome; for example, in the Chinese patent with the authorization announcement number CN211618639U and the patent name of a bilateral snap-type fresh-keeping box, which includes an acrylic box body and an acrylic lid, the acrylic lid can be separated from the acrylic box body. Grooves are respectively arranged on both sides of the acrylic lid, an L-shaped buckle cover and a ventilation hole are arranged in the groove, a sealing column for sealing the ventilation hole is arranged on the inner side surface of the L-shaped buckle cover, and the L-shaped buckle covers on both sides of the acrylic lid need to be opened or closed simultaneously. When opening the lid of this structure, the L-shaped buckle covers on both sides need to be opened simultaneously. At the same time, after frequent use, the snap structure is prone to wear or looseness, thereby affecting the sealing performance and service life of the fresh-keeping box.
[0004] Therefore, how to provide a fresh-keeping box lid that can achieve sealing and locking without using a snap structure and has a convenient opening process is an urgent problem to be solved by those skilled in the art. Content of the Utility Model
[0005] In view of this, the utility model provides a fresh-keeping box lid and its fresh-keeping box, aiming to solve the above technical problems.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A fresh-keeping box lid includes a lid body. The bottom wall of the lid body has an integrally formed and downwardly extending sealing retaining ring. The bottom wall of the sealing retaining ring has an annular edge strip extending outward. The edge of the annular edge strip is bent and upturned. The annular edge strip and the sealing retaining ring form a sealing and buckling part.
[0008] Through the above technical solution, a fresh-keeping box lid provided by the utility model, through the structural arrangement of an integrally formed and downward-extending sealing retaining ring and an annular edge strip, can better achieve the sealing performance between the fresh-keeping box lid and the fresh-keeping box. The structure of the utility model is simple, and the sealing and locking function can be achieved for the fresh-keeping box without using a bayonet structure, that is, it meets the sealing performance and can also achieve the technical effect during the opening process, and is suitable for popularization and use.
[0009] Preferably, in the above-mentioned fresh-keeping box lid, one side of the lid body is a plane, and the other side is a pressing part that slopes upward. When the fresh-keeping box lid is hermetically connected to the fresh-keeping box, there may be a difference in air pressure inside and outside, resulting in negative pressure inside the fresh-keeping box. In this case, through the structural arrangement of the pressing part, it is easier to apply force when opening the fresh-keeping box lid. Press the pressing part, and the other end will tilt up. At the same time, the annular edge strip is forced to separate from the fresh-keeping box, allowing gas to escape and achieving quick opening.
[0010] Preferably, in the above-mentioned fresh-keeping box lid, both ends of the lid body are planes, and both ends of the annular edge strip are integrally formed with pulling strips. The setting of the pulling strips not only enhances the stability of the overall structure but also plays an auxiliary role. When in use, hold the lid body and the pulling strips simultaneously and lift upward. During the lifting process, the annular edge strip moves upward and is forced to separate from the fresh-keeping box, allowing gas to escape and achieving quick opening.
[0011] Preferably, in the above-mentioned fresh-keeping box lid, the pulling strip includes an inclined section and a horizontal section. One end of the inclined section is fixedly connected to the edge of the annular edge strip, and the other end inclines towards the lid body. One end of the horizontal section is fixedly connected to the inclined section, and the other end is a free end.
[0012] Preferably, in the above-mentioned fresh-keeping box lid, the distance from the free end to the central axis of the lid body is greater than the distance from the edge of the lid body to the central axis of the lid body. This is convenient for assisting the lid body to achieve quick opening.
[0013] Preferably, in the above-mentioned fresh-keeping box lid, the bottom wall of the horizontal section has anti-slip strips. This increases the friction of the hand and enables lifting.
[0014] Preferably, in the above-mentioned fresh-keeping box lid, a through hole is opened at the center of the lid body. The through hole communicates with the sealing retaining ring, and a groove is opened on the side wall of the through hole. A cover plate is detachably connected in the groove.
[0015] Preferably, in the above-mentioned fresh-keeping box lid, the cover plate is made of a transparent material. The cover plate made of a transparent material can achieve visualization inside the fresh-keeping box.
[0016] Preferably, in the above-mentioned fresh-keeping box lid, a limiting concave ring is provided on the top surface of the lid body and at the edge of the through hole. The cooperation between the limiting concave ring and the cover plate enables the lid body with the cover plate to act as the base of the fresh-keeping box, preventing the fresh-keeping box from shaking left and right, and effectively ensuring that the items in the fresh-keeping box will not spill to the outside.
[0017] The present utility model also discloses a fresh-keeping box, including the above-mentioned fresh-keeping box lid body and a fresh-keeping box body.
[0018] It can be seen from the above technical solutions that, compared with the prior art, the present utility model discloses a fresh-keeping box lid body, which has the following beneficial effects:
[0019] 1. The present utility model can achieve sealing and locking without using a buckle structure, and the opening process is convenient to achieve.
[0020] 2. Through the setting of the pressing part, the present utility model can separate the annular edge strip from the fresh-keeping box, discharge the internal gas, and achieve quick opening.
[0021] 3. Through the setting of the pulling strip, the present utility model cooperates with the lid body and pulls it upward to separate the annular edge strip from the fresh-keeping box, discharge the internal gas, and achieve quick opening. Description of the Drawings
