Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging boxes, in particular to a take-out packaging box with a heat preservation function. Background Art
[0002] In seasons with lower temperatures, during the takeaway packaging process, in order to make it more convenient for the deliverymen to take the food, hand-held packaging boxes are used to package the food or other items. In actual use, since there are gaps between the hand plates of the hand-held packaging boxes, when storing food that needs to be kept warm, the deliverymen usually put such food into the takeaway insulation box. However, when delivering larger foods (for example, grilled fish with side dishes or pots, which are not convenient to put into the packaging box), it is often difficult to put them directly into the takeaway insulation box. During the delivery process, these exposed packaging boxes are easily exposed to cold air. The gaps between the hand plates easily enter the hand-held packaging boxes, causing the food to cool down quickly. When the food is delivered to the buyer, it has already cooled down.
[0003] In view of the above situation, designers need to design a device to delay the heat loss inside the portable packaging box and reduce the entry of cold air from the outside into the portable packaging box, so as to solve the problem that during the food delivery process, cold air can easily enter the packaging box through the gaps between the takeaway packaging boxes, causing the food to cool down quickly. Utility Model Content
[0004] In order to make up for the shortcomings of the existing technical problems, the purpose of the utility model is to provide a take-out packaging box with insulation function. A sleeve box is arranged on the outside of the box body and is sleeved on the upper end of the box body. The one-piece sleeve box can conveniently isolate the external cold air and prevent the cold air from directly entering the box body from the gap at the upper end of the box body, so as to solve the problem that during the food delivery process, cold air is easy to enter the inside of the take-out packaging box from the gap between the take-out packaging boxes, causing the food to cool down quickly.
[0005] The technical solution of the utility model is as follows:
[0006] A take-out packaging box with a heat preservation function, comprising a box body, two lifting plates distributed on both sides of the box body, lifting holes are provided on the upper ends of the two lifting plates, a sleeve box with openings at both ends is sleeved on the outer side of the box body, a cover plate is provided on one side of the upper end of the sleeve box, the middle part of the cover plate bulges upward, side plates are provided at both ends of the cover plate, and a strip through hole is provided in the middle of the cover plate for the lifting plates to pass through;
[0007] One end of the cover plate located on the other side of the sleeve box is downwardly extended to be provided with a connecting plate, and the connecting plate is glued and connected to the outer wall of the sleeve box.
[0008] Furthermore, a sealing plate which is integrally cut and formed with the box body is provided at the opening above the box body, and the sealing plate as a whole covers the opening above the box body. By arranging the sealing plate to cover the top of the box body, the path for cold air to enter the inside of the box body can be reduced, and the thermal insulation effect inside the box body can be increased.
[0009] Furthermore, the lower end of the side plate extends downward into the interior of the sleeve box, and the lower end of the side plate is glued and connected to the inner wall of the sleeve box.
[0010] Furthermore, the side view projection shape of the cover plate is a triangle, so that the lower part of the lifting plate can be supported on two symmetrical sides of the cover plate, so that the upper ends of the two lifting plates are combined.
[0011] Furthermore, the box body and the sleeve box are both made of corrugated cardboard, and the outer sides of the box body and the sleeve box are coated.
[0012] Furthermore, the inner wall of the box body is compounded with an aluminum foil reflective insulation layer, which is adhered to the inner wall of the box body. By arranging the aluminum foil reflective insulation layer inside the box body, the heat loss on the surface of the box body can be further reduced, the temperature inside the box body can be made more stable, and the thermal insulation effect of the box body can be further improved.
[0013] Furthermore, the width of the strip through hole is equal to twice the thickness of the lifting plate. After the lifting plate passes through the strip through hole, the outer wall of the strip through hole fits tightly with the surface of the lifting plate, which can further reduce the possibility of cold air entering the box body and increase the thermal insulation effect of the box body.
[0014] The advantages of the utility model are:
[0015] 1. The utility model provides a sleeve box on the outer side of the box body and is sleeved on the upper end of the box body. The one-piece sleeve box can conveniently isolate the external cold air, prevent the cold air from directly entering the box body from the gap at the upper end of the box body, and keep the food inside the box body warm for a longer time.
[0016] 2. The setting of the sleeve box of the utility model can not only prevent the outside cold air from entering the inside of the box body (forming a heat preservation buffer area between the sleeve box and the box body), but also reduce the heat loss on the surface of the box body, thereby reducing the temperature difference between the surface of the box body and the air in the internal space of the box body, reducing the heat transfer, and thus extending the insulation time of the food inside the box body.
[0017] 3. The utility model can further reduce the heat loss on the surface of the box body by arranging an aluminum foil reflective insulation layer inside the box body, so as to make the temperature inside the box body more stable and further improve the heat preservation effect of the box body.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] A takeaway packaging box with heat preservation function, such as Figure 1-3 As shown, it comprises a box body 1, and two lifting plates 1-1 are arranged on the top of the box body 1 and distributed on both sides of the box body 1, and lifting holes 101 are arranged on the upper ends of the two lifting plates 1-1, and a sleeve box 2 with openings at both ends is sleeved on the outer side of the box body 1, and a cover plate 2-1 is arranged on one side of the upper end of the sleeve box 2, and the middle part of the cover plate 2-1 bulges upward, and side plates 2-3 are arranged on both ends of the cover plate 2-1, and a strip through hole 201 is arranged in the middle part of the cover plate 2-1 for the lifting plates 1-1 to pass through;

[0025] In the utility model, during use, the food to be delivered is first placed into the box body 1, and then the sealing plate 1-2 is covered on the opening above the box body 1, and then the sleeve 2 is taken out and sleeved on the box body 1 with the opening facing downward. During the sleeve process, the lifting plate 1-1 on the top of the box body 1 passes through the strip through hole 201 at the upper end of the sleeve 2, and then the food loaded into the box body 1 can be conveniently taken out through the lifting plate 1-1; during the delivery process, the one-piece sleeve 2 can conveniently isolate the external cold air, prevent the cold air from directly entering the box body 1 from the gap at the upper end of the box body 1, and can keep the food in the box body 1 warm for a longer time.
[0026] It should be noted that the length of the sealing plate 1-2 is greater than the length of the box body 1, and the sealing plate 1-2 has excess cover on both ends of the box body 1. When the sleeve box 2 is downwardly sleeved on the outside of the box body 1, the excess parts at both ends of the sealing plate 1-2 are bent downward and clamped between the sleeve box 2 and the box body 1.
[0027] In addition, the setting of the sleeve box 2 can not only prevent the outside cold air from entering the box body 1 (forming a heat preservation buffer area between the sleeve box 2 and the box body 1), but also reduce the heat loss on the surface of the box body 1, thereby reducing the temperature difference between the surface of the box body 1 and the air in the internal space of the box body 1, reducing the heat transfer, and thus extending the insulation time of the food in the box body 1.
[0028] It should be noted that during the production stage, the cover plate 2-1 at the upper end of the sleeve box 2 is connected to the other side of the box body 1 through the side plate 2-3, and the side plate 2-3, the cover plate 2-1 and the box body 1 are integrally sheared and formed.
[0029] Furthermore, a sealing plate 1-2 which is integrally cut and formed with the box body 1 is provided at the opening above the box body 1, and the sealing plate 1-2 covers the opening above the box body 1 as a whole. By arranging the sealing plate 1-2 to cover the top of the box body 1, the path for cold air to enter the interior of the box body 1 can be reduced, and the thermal insulation effect inside the box body 1 can be increased.
[0030] Furthermore, the lower end of the side panel 2 - 3 extends downward into the interior of the sleeve box 2 , and the lower end of the side panel 2 - 3 is glued and connected to the inner wall of the sleeve box 2 .
[0031] Furthermore, the side view projection shape of the cover plate 2-1 is a triangle, so that the lower part of the lifting plate 1-1 can be supported on two symmetrical sides of the cover plate 2-1, so that the upper ends of the two lifting plates 1-1 are combined.
[0032] Furthermore, the box body 1 and the sleeve box 2 are both made of corrugated cardboard, and the outer sides of the box body 1 and the sleeve box 2 are coated.
[0033] Furthermore, the inner wall of the box body 1 is compounded with an aluminum foil reflective insulation layer, and the aluminum foil reflective insulation layer is adhered to the inner wall of the box body 1. By arranging the aluminum foil reflective insulation layer inside the box body 1, the heat loss on the surface of the box body 1 can be further reduced, the temperature inside the box body 1 can be made more stable, and the thermal insulation effect of the box body 1 can be further improved.
[0034] Furthermore, the width of the strip through hole 201 is equal to twice the thickness of the lifting plate 1-1. After the lifting plate 1-1 passes through the strip through hole 201, the outer wall of the strip through hole 201 fits tightly with the surface of the lifting plate 1-1, which can further reduce the possibility of cold air entering the interior of the box body 1 and increase the thermal insulation effect of the box body 1.
