[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0023] Embodiment 1: Figures 1 to 4 As shown, the thermal insulation drawer-type paper box described in this embodiment includes an outer box 1 and an inner box 2; the outer box 1 has a first cavity 11, the first cavity 11 is used to provide a moving space for the inner box 2, and a first thermal insulation layer 3 is provided on each cavity wall of the first cavity 11;

[0024] The inner box 2 can be accommodated in the first cavity 11; the inner box 2 has a second cavity 21, the inner bottom wall of the second cavity 21 is provided with a second insulation layer 4, the surrounding side walls of the first cavity 11 are provided with a first insulation paper 5 connected to the second insulation layer 4, and the outer wall of the inner box 2 is provided with a third insulation layer 6.

[0025] It should be noted that the first insulation layer 3 is insulation aluminum foil, the second insulation layer 4 is polystyrene foam board, and the third insulation layer 6 is tin foil. The first insulation paper 5 can be one of glass fiber insulation paper, insulation cotton tin foil, and insulation aluminum foil.

[0026] Specifically, when the thermal insulation drawer-type paper box of this embodiment is used, the second thermal insulation layer 4, the first thermal insulation paper 5 and the third thermal insulation layer 6 work together to reduce the loss of internal temperature, thereby achieving the effect of insulating the internal temperature. At the same time, the first thermal insulation layer 3 effectively prevents the external temperature from eroding the interior, thereby achieving the effect of isolating the external temperature. In this way, through the cooperation of the inside and the outside, the thermal insulation performance of the paper box is improved, which is beneficial to improving the user experience.

[0027] like Figures 1 to 3 As shown, in the thermal insulation drawer-type paper box described in this embodiment, in some embodiments, the outer wall of the outer box 1 is provided with a fourth thermal insulation layer 7. Exemplarily, the fourth thermal insulation layer 7 is a polystyrene film, which is easier to cover the outer wall of the outer box 1. By providing the fourth thermal insulation layer 7, this embodiment further prevents the external temperature from corroding the interior, and further improves the thermal insulation effect of the paper box.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, an outer wall of the inner box 2 is provided with a groove 22, and the groove wall of the groove 22 is provided with a second insulation paper 8 connected to the third insulation layer 6; the third insulation layer 6 is provided with a through hole 61 matching the size of the groove 22 at a position corresponding to the groove 22. In this embodiment, the groove 22 is provided so that the user can pull the inner box 2 through the groove 22, and the structure is more convenient to use; at the same time, the second insulation paper 8 is provided in the groove 22 to further reduce the loss of internal temperature and better the insulation effect of the internal temperature.

[0029] It should be noted that the second thermal insulation paper 8 can be one of glass fiber thermal insulation paper, thermal insulation cotton tin foil paper, and thermal insulation aluminum foil paper. Thermal insulation aluminum foil paper is preferably used.

[0030] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments of the thermal insulation drawer-type paper box described in this embodiment, the groove 22 is located at the center of the outer wall of the inner box 2. This arrangement allows the inner box 2 to be more evenly stressed when the user pulls the inner box 2, and the pulling operation is smoother.

[0031] In the insulation drawer-type paper box described in this embodiment, in some embodiments, the thickness of the second insulation paper 8 is 0.1-0.2 cm. In the insulation drawer-type paper box described in this embodiment, in some embodiments, the thickness of the third insulation layer 6 is 0.1-0.2 cm. In the insulation drawer-type paper box described in this embodiment, in some embodiments, the thickness of the first insulation paper 5 is 0.1-0.2 cm. In the insulation drawer-type paper box described in this embodiment, in some embodiments, the thickness of the first insulation layer 3 is 0.1-0.2 cm.

[0032] Through the above arrangement, the first thermal insulation paper 5, the second thermal insulation paper 8, the first thermal insulation layer 3 and the third thermal insulation layer 6 of this embodiment can achieve thermal insulation effect while occupying less space.

[0033] In some embodiments of the thermal insulation drawer-type paper box described in this embodiment, the thickness of the second thermal insulation layer 4 is 0.15-0.2 cm. This arrangement allows the second thermal insulation layer 4 to have a reliable thermal insulation effect and sufficient support.

[0034] Embodiment 2: Figure 5 As shown, the difference between this embodiment and the first embodiment is that the top periphery of the first thermal insulation paper 5 is also connected to the top periphery of the third thermal insulation layer 6. In this way, the inner box 2 is completely covered, effectively preventing the internal temperature from escaping from the gap between the top periphery of the inner box 2 and the cavity wall of the first cavity, and the thermal insulation effect is further improved. The other structures of this embodiment are the same as those of the first embodiment, and will not be repeated here.

[0035] The above is only a preferred embodiment of the present utility model, so any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the protection scope of the present utility model patent application.
