[0001] This utility model relates to the field of food storage container technology, and in particular to a food storage container that can be conveniently and tightly covered with a food storage film. Background Technology

[0002] Negative pressure food storage containers maintain a tight seal because of the negative pressure inside. However, this seal weakens over time, potentially leading to leaks. Furthermore, if there is liquid in the food, it can accumulate on the lid and even the sealing strip, making cleaning difficult. Most importantly, the preservation effect of traditional food storage containers diminishes over time. Summary of the Invention

[0003] This utility model aims to at least partially solve one of the technical problems in the related art. Therefore, one objective of this utility model is to provide a food storage box that can be easily and tightly covered with cling film, solving problems such as poor preservation effect after prolonged use, easy air leakage, and easy accumulation of soup or liquid on the lid and adhesive strip.

[0004] According to this utility model, a food storage box for convenient and tight covering with plastic wrap includes a box body, a lid, and a plastic wrap covering strip. The top of the box body extends outward to form a widened top edge. The widened top edge has an annular notch at the bottom of the box body. The upper surface of the widened top edge has an annular groove with an inverted mushroom-shaped cross-section. The plastic wrap covering strip includes an annular plug and an annular pad. The lower surface of the annular plug and the annular pad are integrally formed. When the plastic wrap is laid on the top opening of the box body and extends outward, the annular plug is inserted into the annular groove, squeezing the plastic wrap into the groove. The lid has flexible connecting strips on all four sides. The lower surface of the lid has a raised strip. When the lid is fastened to the top of the box body, the raised strip is secured to the inner wall of the top of the box body. The hooks on the flexible connecting strips are engaged in the annular notch. The lid has an air vent.

[0005] In some embodiments of this utility model, the annular rubber stopper is interference-fitted into the annular stopper groove, and the annular rubber pad is attached to the upper surface of the widened top edge and has the same width as the widened top edge.

[0006] In some other embodiments of this utility model, the lid has multiple annular protrusions on its lower surface near the edge.

[0007] In some other embodiments of this utility model, the thickness of the annular rubber pad is 4-6mm, and the annular rubber pad has a plurality of raised rubber ridges on the lower surface of both sides of the annular rubber plug, the thickness of the raised rubber ridges being 1-2mm.

[0008] In some other embodiments of this utility model, the venting component includes a retaining strip and a fastening plug and a loosening plug fixed at both ends of the lower surface of the retaining strip. The box cover is provided with a thickened mounting plate in the middle. The thickened mounting plate is provided with a retaining strip groove. The retaining strip groove is provided with a first plug hole and a second plug hole. The fastening plug is forcefully inserted into the first plug hole, and the loosening plug is interference-fitted into the second plug hole.

[0009] In this invention, a loose layer of cling film is laid on the box body, and the cling film is inserted into the annular groove with an annular rubber stopper, so that the cling film seals the box body. After the lid is closed, it can be effectively squeezed and sealed, and the cling film is not easy to loosen or be removed. The soup will only stick to the cling film. The cling film can be removed by peeling off the cling film covering strip, and it will not stick to the lid or the cling film covering strip. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0016] Referring to Figures 1-2, a food storage box for convenient and tight coverage with cling film includes a box body 1, a lid 2, and a cling film covering strip. The top of the box body 1 extends outward to form a widened top edge. The widened top edge has an annular notch 7 at the bottom of the box body. The upper surface of the widened top edge has an annular groove 6, which has an inverted mushroom-shaped cross-section. The cling film covering strip includes an annular plug 51 and an annular pad 5. The lower surfaces of the annular plug 51 and the annular pad 5 are integrally formed. The plastic wrap 8 is laid on the top opening of the box body 1 and extended outward. The annular rubber stopper 51 is inserted into the annular stopper groove 6 and the plastic wrap 8 is squeezed into the annular stopper groove 6. The box cover 2 is provided with flexible connecting strips 4 on all four sides. The lower surface of the box cover 2 is provided with a ring of raised strips 22. The box cover 2 is fastened on the top of the box body 1. The ring of raised strips 22 is just locked on the inner wall of the top of the box body 1. The hooks on the flexible connecting strips 4 are locked in the annular slots 7. The box cover 2 is provided with a venting device.

[0017] The traditional adhesive strip that is attached to the bottom of the lid has been replaced with an adhesive strip covered by plastic wrap. An annular groove 6 is provided on the widened top edge so that when installing the plastic wrap 8, the annular plug 51 is inserted into the annular groove 6, so that the plastic wrap is squeezed into the annular groove 6. The plastic wrap 8 seals the box body 1, and then the lid is closed. At this time, the plastic wrap also plays a role in preservation, and the airtightness is increased. Soup will only stick to the plastic wrap. The plastic wrap can be removed by removing the plastic wrap covering strip. Soup will not stick to the lid 2 and the plastic wrap covering strip, resulting in better preservation effect.

[0018] The annular rubber stopper 51 is interference-fitted into the annular stopper groove 6, and the annular rubber gasket 5 is attached to the upper surface of the widened top edge and has the same width as the widened top edge. The interference fit provides a better seal, and the annular rubber gasket 5 can be laid flat on the widened top edge for a better fit and seal.

[0019] The lid 2 has multiple annular protrusions 23 on its lower surface near the edge. The annular protrusions 23 can easily compress the annular rubber gasket 5 to deform it, thereby increasing the sealing performance.

[0020] The annular rubber pad 5 has a thickness of 4-6 mm. The annular rubber pad 5 has multiple raised rubber ridges on the lower surface of both sides of the annular rubber stopper 51, and the thickness of these raised rubber ridges is 1-2 mm. Because the widened top edge is made of glass, the raised rubber ridges are more easily deformed and compressed when the annular rubber pad 5 is squeezed, resulting in a better fit.

[0021] The venting component includes a retaining strip 3 and fastening and loosening plugs fixed at both ends of the lower surface of the retaining strip 3. The cover 2 has a thickened mounting plate in the middle, and the thickened mounting plate has a retaining strip groove. The retaining strip groove has a first plug hole and a second plug hole 21. The fastening plug is forcefully inserted into the first plug hole, and the loosening plug is interference-fitted into the second plug hole 21. The fastening plug is not easily pulled out to prevent the retaining strip 3 from falling off or being pulled out. The loosening plug, inserted into the second plug hole 21, can seal the second plug hole 21, but can also be pulled out.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
