[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The words "first", "second", etc. mentioned in this article are only for the convenience of describing two or more structures or components with the same or similar structures and / or functions, and do not imply any special limitation on the order and / or importance.

[0025] Please refer to Figure 1-3 , Figure 1 This is a structural schematic diagram of another specific embodiment of the box body provided by the present invention. Figure 2 for Figure 1 The first part of the expansion diagram is shown, and the local cross-sectional structure is displayed. Figure 3 for Figure 1 The expanded view of the second part shows the local cross-sectional structure.

[0026] like Figure 1-Figure 3 As shown, the present invention provides a box body, including a first split body B and a second split body C, the first split body B and the second split body C both include three box wall parts, and a first folding mark B1 is arranged between the three box wall parts of the same split body; the box wall part located in the middle of the three box wall parts of the first split body B is an upper box wall 11, and the box wall parts located on both sides (forming two lateral box walls 13 of the box body 1) can be connected to the second split body C, the box wall part located in the middle of the three box wall parts of the second split body C is a lower box wall 12, and the box wall parts located on both sides (forming the other two lateral box walls 13 of the box body 1) can be connected to the first split body B; the first split body B and the second split body C are both made of cardboard, and in the assembled state, the paper grain direction of the box wall parts located on both sides of the three box wall parts of the first split body B is in a state perpendicular to the upper box wall 11 and the lower box wall 12, and the paper grain direction of the box wall parts located on both sides of the three box wall parts of the second split body C is in a state perpendicular to the upper box wall 11 and the lower box wall 12.

[0027] It should be noted that for single-structure paperboards, such as grey board and mounted paper, when paper is prepared, most of the fibers extend in the same direction, which can be called the paper grain direction of the paperboard; for composite paperboards, such as corrugated paperboard, which generally has more than one layer of corrugated core D, the extension direction of the corrugated core D can be called the paper grain direction of the corrugated paperboard.

[0028] Taking the first split body B and the second split body C made of corrugated cardboard as an example, the above structure is adopted. In the embodiment of the present invention, the first split body B and the second split body C are assembled into two pieces of corrugated cardboard to form a box body 1, and each split body includes three box wall parts. In this way, in the assembled state, the corrugated core D of the box wall parts located on both sides of the three box wall parts of the first split body B and the corrugated core D of the box wall parts located on both sides of the three box wall parts of the second split body C can be in a state perpendicular to the upper box wall 11 and the lower box wall 12, so that the extension direction of the corrugated core D in each lateral box wall 13 can be the same as the force direction, thereby greatly improving the supporting performance of the lateral box wall 13 of the box body 1 to ensure the structural strength of the box body 1.

[0029] For ease of description, the box wall portions located on both sides of the three box wall portions of the first split body B can be referred to as the lateral box wall 13 of the first split body B, and the box wall portions located on both sides of the three box wall portions of the second split body C can be referred to as the lateral box wall 13 of the second split body C. Here, the embodiment of the present invention does not limit the connection structure and connection part between the lateral box wall 13 of the first split body B and the second split body C, and the connection structure and connection part between the lateral box wall 13 of the second split body C and the first split body B. In specific implementation, those skilled in the art can design according to actual needs as long as the reliability requirements of the connection can be met. Generally speaking, the connection method between the above two split bodies can be bonding, plugging, clamping, etc.

[0030] In the scheme of the accompanying drawings, Figure 2 , Figure 3 As shown, the two lateral box walls 13 of the first split body B may be provided with a first clamping piece 132 at the end away from the upper box wall 11, and the first split body B may be clamped with the second split body C through the first clamping piece 132; the two lateral box walls 13 of the second split body C may be provided with a second clamping piece 133 at the end away from the lower box wall 12, and the second split body C may be clamped with the first split body B through the second clamping piece 133.

[0031] The connection parts between the two clamping parts and another split body are not limited here. Taking the first clamping part 132 as an example, it can be connected to the two side box walls 13 of the second split body C and directly connected to the lower box wall 12.

[0032] Specifically, the two lateral box walls 13 of the second split body C may also be provided with a first snap-fitting portion 134, and in the assembled state, the first snap-fitting member 132 may be directly snap-fitted with the first snap-fitting portion 134 on the lateral box wall 13. The first snap-fitting portion 134 is located at the end of the lateral box wall 13 of the second split body C close to the lower box wall 12, and its specific structural form may be a snap-fitting slot, and the snap-fitting slot may adopt a shrinking design, that is, the slot size of the snap-fitting slot is smaller than the slot inner size, so that the first snap-fitting member 132 is not easy to fall out after being snapped into the slot.

[0033] The snap-fit ​​structure of the first split body B can be a second snap-fit ​​portion provided on the upper box wall 11. In the assembled state, the second snap-fit ​​member 133 can be snap-fitted with the second snap-fit ​​portion. In detail, the second snap-fit ​​portion can be an insertion hole 111 provided on the upper box wall 11. The insertion hole 111 is used to hold the object to be held. The object to be held can generally be a cup of beverages, food, etc. The cup used for holding can generally be a tapered structure with a thick top and a thin bottom. In this way, the cup can be directly snapped into the insertion hole 111 for easy transportation.

[0034] The second clamping member 133 may be T-shaped. In the assembled state, the second clamping member 133 can extend into the insertion hole 111 and abut against the upper wall surface of the upper box wall 11 through the transverse portion of the T, thereby connecting the second split body C and the first split body B.

[0035] The above-mentioned insertion hole 111 can be set not only in the upper box wall 11, but also in the lower box wall 12, or can be set in both the upper box wall 11 and the lower box wall 12 at the same time, and the specific setting can be made according to actual needs.

[0036] Furthermore, a protective sheet 113 may be included. The protective sheet 113 may be connected to the hole wall of the insertion hole 111, and a second folding mark 113a may be provided at the connection between the two. The protective sheet 113 may be flipped around the second folding mark 113a. In the plugged state, the protective sheet 113 may be flipped to fit the outer wall of the object to be contained so as to increase the contact area with the object to be contained, which is beneficial to ensure reliable fixation of the object to be contained.

[0037] As shown in the figure, the number of the above-mentioned protective sheets 113 can be multiple, and each protective sheet 113 can be distributed at intervals along the circumferential direction, so that a protective sheet 113 can be fitted to multiple positions on the circumferential direction of the outer wall of the object to be contained, so as to improve the uniformity of the circumferential force on the object to be contained as much as possible, and can ensure the reliability of the positioning of the object to be contained to a greater extent.

[0038] Here, the embodiment of the present invention does not limit the flipping direction of the protective sheet 113, which can be turned outward, that is, turned to the outside of the box body 1, or turned inward, that is, turned to the inside of the box body 1, which can be determined in combination with actual conditions.

[0039] The protective sheet 113 may be in the shape of a fan ring, or other shapes, and its outer edge may be connected to the inner wall of the insertion hole 111 through the aforementioned second folding mark 113a. The protective sheet 113 may also be provided with at least one easy-to-break mark 113b, and each easy-to-break mark 113b may extend from the inner edge to the outer edge of the protective sheet 113; in this way, after the object to be contained is inserted into the insertion hole 111, due to the abutment between the outer wall of the object to be contained and the protective sheet 113, the inner edge of the protective sheet 113 may be divided into a plurality of segments along each easy-to-break mark 113b, and each segment may be better matched with the outer wall (usually an arc-shaped cylinder) of the object to be contained, so that the protective sheet 113 and the outer wall of the object to be contained may have a larger contact area, which may improve the uniformity of the circumferential force of the object to be contained to a greater extent, and further ensure the reliable positioning of the object to be contained and the insertion hole 111.

[0040] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
