[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0025] Please see Figure 1-5 A sterile cardboard box with heat preservation and refrigeration function includes a receiving mechanism 1. The receiving mechanism 1 includes a cardboard box body 101. Each of the four bottom corners of the cardboard box body 101 is fixedly connected to a pad 102, which is a rubber block. The pads 102 provide support for the cardboard box body 101. The cardboard box body 101 is used to contain food to be refrigerated. A matching cardboard box lid 103 is provided on top of the cardboard box body 101, which is used to close the top of the cardboard box body 101. Adhesive paper 204 is fixedly connected to the bottom four sides of the cardboard box lid 103. The adhesive paper 204 is adapted to the outer wall of the cardboard box body 101 and is used to adhere to the cardboard box body 101, thereby fixing the cardboard box body 101 and the cardboard box lid 103.
[0026] A rubber sealing ring 108 is fixedly connected to the top of the cardboard box body 101. The rubber sealing ring 108 is adapted to the inner top of the cardboard box lid 103. The rubber sealing ring 108 is used to seal the gap between the cardboard box body 101 and the cardboard box lid 103 after the cardboard box lid 103 is closed, thereby improving the overall heat insulation performance of the cardboard box. A polyurethane foam layer 105 is fixedly connected to the inner wall of both the cardboard box body 101 and the cardboard box lid 103. The polyurethane foam layer 105 can improve the overall heat insulation performance of the cardboard box to meet the needs of food refrigeration. A silver ion antibacterial film 104 is fixedly connected to the inner wall of both the polyurethane foam layer 105. The silver ion antibacterial film 104 can effectively improve the antibacterial properties of the entire cardboard box. A waterproof film 107 is fixedly connected to the outer wall of both the cardboard box body 101 and the cardboard box lid 103. The waterproof film 107 can improve the overall waterproof performance of the cardboard box, thereby reducing the probability of the box being damaged by moisture.
[0027] The top of the cardboard box lid 103 has an observation opening 109, which facilitates the observation of the food stored inside the cardboard box 101. Inside the observation opening 109 is a fixing frame 110 fixedly connected to the cardboard box lid 103. A transparent plastic plate 106 is fixedly connected inside the fixing frame 110. The transparent plastic plate 106 and the fixing frame 110 are used to seal the observation opening 109, while still allowing observation of the food stored inside the cardboard box 101 through the transparent plastic plate 106. Two sets of transparent plastic plates 106 are fixedly connected, forming a double-layer structure to reduce heat exchange efficiency and thus improve the overall insulation performance of the cardboard box. A cover plate 111 is located on top of the cardboard box lid 103. The cover plate 111 is adapted to fit the fixing frame 110, and its arrangement closes the fixing frame 110.
[0028] The opening mechanism 2 includes an easy-tear strip 201 evenly and fixedly connected to the periphery of the cardboard box lid 103. The easy-tear strip 201 is designed to divide the cardboard box lid 103 into upper and lower parts when torn, so that the cardboard box 101 can be opened by removing the upper part of the cardboard box lid 103, thus eliminating the need to peel off the sets of adhesive papers 204, making the cardboard box 101 more convenient to open. An adhesive tape 203 is fixedly connected to the easy-tear strip 201 inside the cardboard box lid 103. The adhesive tape 203 reduces the probability of the pull tab 202 breaking during the tearing process. A pull tab 202 is fixedly connected to one end of the easy-tear strip 201. Both the adhesive tape 203 and the pull tab 202 extend to the outside of the cardboard box lid 103, and the pull tab 202 facilitates tearing the easy-tear strip 201.
[0029] In this embodiment, the silver ion antibacterial film 104 and the waterproof film 107 are existing technologies and will not be described in detail here.
[0030] In use, place the food to be refrigerated inside the cardboard box 101, then close the cardboard box lid 103 onto the top of the cardboard box 101 until the rubber sealing ring 108 is pressed against the inner top wall of the cardboard box lid 103, thereby sealing the cardboard box 101. Next, adhere and fix each set of self-adhesive paper 204 to the outer wall of the cardboard box 101, thereby fixing the cardboard box lid 103 to the cardboard box 101. Then, close the cover plate 111 on top of the fixing frame 110. The entire cardboard box and the food packaged inside can then be refrigerated. Due to the polyurethane foam layer 105, the insulation performance of the entire cardboard box is effectively improved, enabling the entire cardboard box to meet the requirements of refrigeration. When it is necessary to check the freshness of the refrigerated food inside the cardboard box 101, the cover 111 can be removed from the top of the fixing frame 110. Then, the freshness of the refrigerated food inside the cardboard box 101 can be checked through the two sets of transparent plastic plates 106. When it is necessary to take out the food inside the cardboard box 101, simply pinch the pull tab 202 and the tape 203 with your fingers, and tear the easy-tear strip 201 from the periphery of the cardboard box cover 103 to separate the upper and lower parts of the cardboard box cover 103. Then, the upper part of the cardboard box cover 103 can be removed from the top of the cardboard box 101 to open the cardboard box 101. Then, the food stored inside the cardboard box 101 can be taken out.
[0031] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
