Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a food preservation box. Background Art

[0002] Typically, when transporting frozen foods at room temperature, ice packs are placed inside the food packaging to lower the temperature. However, since the interior of the food packaging only contains a cubic space defined by the box's width, length, and height, it's difficult to effectively utilize the space. Consequently, the refrigerant is often stored in a separate bag mixed with the food, a mixed storage method that can easily contaminate the fresh food. Utility Model Content

[0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide a food preservation box to solve the problem that the existing food preservation boxes easily contaminate the food due to the mixing of refrigerant and food.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] The present application provides a food preservation box, which includes an upper cover, a middle box body and a lower box body. The middle box body is formed with a food storage cavity for accommodating and storing preserved food, and the lower box body is formed with a refrigerant storage cavity for accommodating and storing refrigerant. Step portions for installing and placing the middle box body are formed on the opposite side walls of the refrigerant storage cavity. When the middle box body is placed in place on the step portions of the lower box body, the upper cover can be closed and installed on the top surface of the lower box body.

[0006] Furthermore, a plurality of through holes are formed at intervals along the length direction of the bottom end surface of the food receiving cavity of the middle box body, and the through holes are long strip-shaped opening structures extending along the width direction of the middle box body.

[0007] Furthermore, a gripping notch is formed on one side of the notch of the through hole for easy gripping.

[0008] Furthermore, the height of the step portion is such that when the middle box body is placed on the step portion, the bottom end surface of the middle box body is flush with the top end of the refrigerant placed in the refrigerant accommodating chamber.

[0009] The beneficial effects of the present invention are as follows: by adopting a split structure of the top cover, the middle box body and the lower box body, the refrigerant is stored in the refrigerant receiving chamber formed by the lower box body, and the food to be kept fresh is placed in the food receiving chamber formed by the middle box body, so that the food to be kept fresh and the refrigerant are placed separately, and the refrigerant does not cause contamination to the food; and the refrigerant located below can provide cold air to the fresh-keeping food above, reduce the temperature around the fresh-keeping food, and prevent the fresh-keeping food from being spoiled due to high temperature.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] See attached Figure 1 To the attached Figure 3 As shown, this embodiment provides a food preservation box 10, which includes an upper cover 100, a middle box body 200 and a lower box body 300. The longitudinal and width dimensions of the outer periphery of the upper cover 100 are the same as the outer periphery dimensions of the middle box body 200 and the lower box body 300. In this way, when the upper cover 100, the middle box body 200 and the lower box body 300 are installed together, a single rectangular hexahedron can be formed as a whole.

[0019] Combined with reference to Figure 3 and attached Figure 4As shown, the middle box body 200 is formed with a food receiving cavity 201 for storing fresh food, and in order to better allow the cold air of the refrigerant below (in the lower box body 300) to enter the middle box body 200, a plurality of through holes 202 are opened on the end surface of the food receiving cavity 201, and the plurality of through holes 202 are evenly spaced along the length direction of the middle box body 200.

[0020] The provision of the through hole 202 allows the refrigerant placed in the lower box body 300 to better cool the fresh food stored in the middle box body 200, that is, the cold air generated by the refrigerant can enter the upper middle box body 200 through the through hole 202, cool the fresh food, and slow down the rate of spoilage of the fresh food.

[0021] Continue to refer to the attached Figure 3 and 4 As shown, in this embodiment, the opening direction of a single through hole 202 extends along the width direction of the middle box body 200. This arrangement ensures that there is sufficient distance between two adjacent through holes 202, that is, the through holes 202 are elongated and extend along the width direction of the middle box body 200. Conversely, if the opening direction of a single through hole 202 extends along the length direction of the middle box body 200, the distance between two adjacent through holes 202 is small, resulting in a weak supporting strength at the bottom of the middle box body 200, which can easily cause the middle box body 200 to be damaged during packaging or transportation.

[0022] Continue to refer to the attached Figure 3 and 4 As shown, in order to facilitate the operator to take out the middle box body 200, a holding notch 203 is formed at the center of one side of the through hole 202 for the operator to hold.

[0023] When fresh food is stored in the middle box 200, the volume of the stored fresh food can be determined by the distance between the inner periphery of the upper cover 100 and the bottom surface of the middle box 200. The space formed between the bottom surface of the middle box 200 and the upper cover 100 is referred to as the first storage area. When the fresh food is stored in the first storage area, cool air from the lower box 300 can be received below the fresh food through the through hole 202.

[0024] Refer to the attached Figure 3 and attached Figure 5As shown, the lower box body 300 is formed with a refrigerant receiving chamber 301 for accommodating and storing refrigerant, and steps 302 are formed on opposite sides of the refrigerant receiving chamber 301 to form a step with the bottom surface of the lower box body 300. The step 302 is formed along the longitudinal direction of the lower box body 300. The step 302 forms a step with the bottom surface of the lower box body 300 so that after the middle box body 200 is placed on the step 302, the refrigerant can be directly stored in the space formed between the steps 302 on both sides. In addition, the height of the step 302 is formed so that when the middle box body 200 is placed on the step 302, the bottom end surface of the middle box body 200 is flush with the top of the refrigerant placed in the refrigerant receiving chamber 301. Of course, in some embodiments, the height of the step portion 302 may also be higher than the height of the top of the refrigerant after the refrigerant is stored. In this way, after the middle box body 200 is placed in place on the step portion 302, a gap is formed between the bottom surface of the middle box body 200 and the top surface of the refrigerant. Then, the cold air generated by the refrigerant can enter the middle box body 200 through the gap and the through hole 202. That is to say, a convection space for cold air flow is created between the middle box body 200 and the lower box body 300.

[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
