Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, and particularly relates to a packaging carton with a heat preservation layer. Background Art

[0002] Cartons are the most widely used packaging products, and their usage has always been the first among various packaging products. Corrugated cartons have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force in transportation packaging. With the improvement of living standards and the leap of the industry, after transformation, heat preservation cartons have attracted the attention of major industries with the concepts of safety, environmental protection, cold preservation, heat preservation, and convenience in carrying.

[0003] For example, the patent document with the application number 201920547139.6 discloses a heat-insulating packaging carton. The utility model discloses a heat-insulating packaging carton, belonging to the technical field of packaging cartons, including a box shell. Sealing strips are arranged at the tops of both ends of the box shell. A first cover plate is arranged on one side of the top of the box shell. A first groove is arranged on the side of the first cover plate away from the box shell. A first convex block is arranged on the side of the first groove away from the first cover plate. A second cover plate is arranged on the side of the top of the box shell away from the first cover plate. Through the first heat preservation layer arranged on one side of the support plate and the second heat preservation layer arranged on the side of the support plate away from the first heat preservation layer, the double heat preservation layers make the heat preservation effect of the carton better, so that the temperature inside the carton is not easy to dissipate. The first sponge layer and the second sponge layer also have the effect of heat preservation. The support plate arranged inside the box shell makes the support force of the box shell stronger. The cooperation of the first groove and the second convex block and the cooperation of the second groove and the first convex block make the first cover plate and the second cover plate bite each other. However, for this heat-insulating packaging carton, after the packaging box is sealed with the upper cover plate, gaps will inevitably occur at the sealing position. If the size of the gaps cannot be controlled, heat loss will occur, affecting the heat preservation effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a packaging carton with a heat preservation layer is proposed. Content of the Utility Model

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 2 shown, for a packaging carton with a thermal insulation layer, side plates 101 are provided on both sides of the upper end of the carton body 1, and an upper cover plate 2 is provided at the upper end of the carton body 1. The advantage of this setting is that by providing the upper cover plate 2, the carton body 1 can be closed.

[0021] Furthermore, a thermal insulation pad 1 201 is provided on the surface of the upper cover plate 2, side cover plates 1 202 are provided on both sides of the upper cover plate 2, and a double-sided adhesive tape 1 203 is provided on the surface of the side cover plate 1 202. A front cover plate 204 is provided at the front end of the upper cover plate 2, and a double-sided adhesive tape 2 205 is provided on the surface of the front cover plate 204. The advantage of this setting is that by providing the side cover plate 1 202 and the front cover plate 204, when the upper cover plate 2 closes the carton body 1, the gap at the closing part can be blocked to reduce heat loss, and at the same time, the heat inside the carton body 1 can be prevented from flowing out, reducing the heat loss speed inside the carton body 1 and improving the heat insulation ability of the carton body 1.

[0022] As Figures 3 - 4 shown, a waterproof film 3 is provided on the inner wall of the carton body 1, and the waterproof film 3 is made of polytetrafluoroethylene. The advantage of this setting is that by providing the waterproof film 3, the moisture-proof ability of the carton body 1 can be improved, and water vapor can be prevented from entering the inside of the carton body 1.

[0023] Furthermore, a grille plate 4 is installed at the bottom of the carton body 1, and a placing bottom plate 401 is provided at the upper end of the grille plate 4. The advantage of this setting is that by providing the grille plate 4, the anti-drop and anti-seismic abilities of the carton body 1 can be improved while achieving a certain heat insulation effect.

[0024] Further, support columns 402 are provided at the four corners of the placement bottom plate 401, and the support columns 402 are in contact connection with the inner wall corners of the carton main body 1. A support cross plate 403 is provided on the surface of the support columns 402, and a second heat insulation pad 301 is provided at the gap of the support cross plate 403. The advantage of this setting is that through the setting of the support columns 402 and the support cross plate 403, the surface strength and impact resistance of the carton main body 1 are improved, and the deformation caused by extrusion and collision is avoided, which affects the heat insulation performance.

[0025] Working principle: When using the packaging carton with a heat insulation layer, first, after inserting the placement bottom plate 401 with the grid plate 4 into the inside of the carton main body 1, after putting the items to be heat-insulated into the inside of the carton main body 1, cover the upper cover plate 2 on the carton main body 1, and then fit the first side cover plate 202 and the front cover plate 204 at the closing gap, and use the first double-sided tape 203 and the second double-sided tape 205 for sealing and heat insulation. After the carton main body 1 is collided, the support columns 402 and the support cross plate 403 at the four corners of the placement bottom plate 401 support to prevent the carton main body 1 from deforming and affecting the heat insulation effect. This is the working principle of the packaging carton with a heat insulation layer.
