Example

[0038] This embodiment provides a military multi-overlapping packaging box 10, as shown in the reference. Figure 1 As shown, it includes a detachably connected housing 100 and a cover 200.

[0039] Specifically, such as Figure 2 and Figure 3 As shown, the upper surface of the box 100 is recessed inward to form a box receiving groove 111. The box receiving groove 111 is generally trapezoidal in shape, and its area gradually decreases along the direction near the bottom of the groove. Figure 4 As shown, the lower surface of the cover 200 is recessed inward to form a cover receiving groove 210. The cover receiving groove 210 is generally trapezoidal in shape, and its area gradually decreases along the direction near the bottom of the groove. When the box 100 and the cover 200 are engaged, the box receiving groove 111 and the cover receiving groove 210 are connected to form a whole, providing ample storage space.

[0040] like Figure 3 and Figure 5 As shown, four support pillars 150 protrude from the lower surface of the box 100, with each pillar 150 located at one of the four corners of the lower surface. A slot 151 for forklift insertion is formed between two support pillars 150. Each support pillar 150 has an inwardly recessed lower surface forming a stacking groove 152, with the four stacking grooves 152 arranged symmetrically. The upper surface of the cover 200 has four stacking blocks 240 corresponding to the four stacking grooves 152. The cooperative design of the stacking grooves 152 and stacking blocks 240 improves stacking stability. The symmetrical design allows the upper military multi-overlap packaging box 10 to be stacked with the lower military multi-overlap packaging box 10 even after rotating 180 degrees, improving stacking convenience. Furthermore, when multiple military multi-overlap packaging boxes 10 are stacked together, the slots 151 facilitate forklift handling.

[0041] Furthermore, such as Figure 4 As shown, a guide platform 242 is provided on the upper surface of the cover 200. The guide platform 242 is generally trapezoidal in shape, and its area gradually decreases along the direction away from the cover 200. The height of the guide platform 242 is slightly lower than that of the stacking block 240. The projections of the four support columns 150 on the upper surface of the cover 200 do not overlap with the guide platform 242. When the forklift fork is inserted into the slot 151, as the insertion proceeds, the military multi-stack packaging box 10 above will be lifted under the guidance of the guide platform 242, allowing the stacking block 240 to detach from the stacking slot 152.

[0042] like Figure 2 and Figure 4 As shown, the box body 100 includes two side walls 130 located on both sides of its length, and each side wall 130 is provided with a latch 131; the lid 200 includes two side walls 250 located on both sides of its length, and each side wall 250 is provided with a locking part 251 that cooperates with the latch 131. The box body 100 and the lid 200 are locked together by the latch 131. The positions of the latches 131 on the two side walls 130 are symmetrical, so that the lid 200 can perfectly match the box body 100 even if it is rotated 180 degrees in the horizontal plane, increasing the convenience of locking.

[0043] like Figure 6 and Figure 7As shown, the lower edge of the cover 200 has an outwardly protruding cover edge 220, and the bottom of the cover edge 220 has a sealing groove 221 that surrounds the lower edge of the cover 200. A sealing strip 222 made of elastic material is embedded in the sealing groove 221. The upper edge of the box 100 has an outwardly protruding box edge 120 that surrounds the upper edge of the box 100. A sealing ridge 121 is provided at the top of the box edge 120 that surrounds the upper edge of the box 100 and corresponds to the position of the sealing groove 221. The sealing ridge 121 can be inserted into the sealing groove 221 to compress the sealing strip 222, causing the sealing strip 222 to deform and fill the gap between the sealing groove 221 and the sealing ridge 121, thereby improving the sealing performance.

[0044] like Figure 2 and Figure 3 As shown, the box 100 includes two end walls 140 located at both ends along its length, and each end wall 140 is provided with a handle 141. When carried by two people, the box 100 can be lifted by grasping the handles 141 at both ends.

[0045] Furthermore, the box end wall 140 includes a first end wall and a second end wall 1401 disposed opposite to each other. A pull rod 153 is provided on the lower surface of the box 100. The pull rod 153 can extend and retract along the length of the box 100 and can be pulled out from the first end wall. A pair of rollers 154 are provided at the bottom of the second end wall 1401 of the box 100, and the pair of rollers 154 are respectively disposed on both sides of the box 100. For single-person handling, the pull rod 153 and the rollers 154 can be used together to complete the task.

[0046] like Figure 8 and Figure 9 As shown, the bottom of both the housing accommodating groove 111 and the cover accommodating groove 210 are staggered with multiple transverse reinforcing ribs 112 and multiple longitudinal reinforcing ribs 113. The staggered reinforcing ribs can increase the overall strength of the housing 100 and the cover 200.

[0047] In addition, the bottom of the cover receiving groove 210 is provided with a first oblique reinforcing rib 213 and a second oblique reinforcing rib 214. The first oblique reinforcing rib 213 extends from the projection position of the stacked block 240 on the bottom of the groove to a corner of the bottom of the groove closest to the stacked block 240. The second oblique reinforcing rib 214 extends from the projection position of the stacked block 240 on the bottom of the groove to the middle of the end wall 230 of the cover closest to the stacked block 240. Because the stacked block 240 changes the stress distribution of the cover 200, the stress on the four corners of the cover 200 increases, while the first oblique reinforcing rib 213 and the second oblique reinforcing rib 214 can strengthen the four corners of the bottom of the cover receiving groove 210, extending the service life of the cover 200.

[0048] like Figure 2 As shown, the top of the box edge 120 is also provided with multiple positioning protrusions 122. These protrusions 122 are positioned along the edge of the groove of the box receiving groove 111 and are located inside the sealing strip 222. When the box body 100 and the cover 200 are fastened together, the positioning protrusions 122 are precisely engaged with the edge of the groove of the cover receiving groove 210, thereby positioning the cover 200 and facilitating the precise fastening of the cover 200 and the box body 100.

[0049] A vent valve 133 is installed on the box 100, which connects the accommodating cavity of the box 100 to the outside. Through the vent membrane in the vent valve 133, air can pass freely, but water molecules are prevented from passing through. This not only ensures the dryness of the contents, but also effectively maintains the air pressure balance inside and outside the military multi-layer packaging box 10, preventing negative pressure and bulging under different air pressure conditions, thus better demonstrating its environmental adaptability.

[0050] Furthermore, both sides of the latch 131 are provided with first protective ridges 132. The first protective ridges 132 are arranged vertically, and their lower surfaces are both horizontal and on the same horizontal plane, namely the first horizontal plane 1321, for abutting against the upper surface of the edge 120 of the other box 100; the lower edge of the latch 131 is higher than the first horizontal plane 1321. On the one hand, the first protective ridges 132 can protect the latch 131; on the other hand, such as Figure 10 As shown, when the lower surface of the first protective ridge 132 is stacked between the boxes 100, it can abut against the edge 120 of the lower box 100, thus forming a support. A second protective ridge 142 is provided on both sides of the handle 141. The second protective ridge 142 is arranged vertically, and its lower surface is horizontal and coplanar with the first horizontal plane 1321; the lower edge of the handle 141 is higher than the first horizontal plane 1321. When the handle 141 is in a naturally drooping state, the second protective ridge 142 can protect the handle 141. Simultaneously, when the lower surface of the second protective ridge 142 is stacked between the boxes 100, it can also abut against the edge 120 of the lower box 100, forming a new support point. The main advantage of this design is that during the production process, when the boxes 100 need to be stored separately, they can be stacked individually, thus saving space.

[0051] like Figure 4 and Figure 11As shown, a third protective ridge 252 is provided on both sides of the engaging portion 251. The third protective ridge 252 protrudes outward in a horizontal direction from the side wall 250 of the cover and the cover edge 220, extending beyond the engaging portion 251. The upper surface of the third protective ridge 252 is horizontally positioned, and the upper surfaces of all the third protective ridges 252 are on the same horizontal plane, i.e., the second horizontal plane 2311, for abutting against the lower surface of the cover edge 220 of the other cover 200. Simultaneously, multiple first reinforcing ribs 231 are provided on both end walls 230 of the cover. The first reinforcing ribs 231 are vertically positioned, connecting the upper surfaces of the end walls 230 and the cover edge 220. The multiple first reinforcing ribs 231 are spaced apart along the width direction of the cover 200, and the upper surfaces of the multiple first reinforcing ribs 231 are all horizontally positioned and coplanar with the first horizontal plane. The upper surfaces of the first reinforcing ribs 231 can form new support points, strengthening the support for the side wall 250 of the cover. Figure 12 As shown, when multiple covers 200 are stacked, the upper surface of the protective ridge can cooperate with the first reinforcing rib 231 to simultaneously support the lower surface of the cover edge 220 of the upper cover 200. Furthermore, the upper surfaces of the four stacking blocks 240 are horizontally positioned on the same horizontal plane, namely the third horizontal plane 241, to abut against the bottom of the cover receiving groove 210 of another cover 200. The distance from the second horizontal plane 2311 to the lower edge of the cover edge 220 is equivalent to the distance from the third horizontal plane 241 to the bottom of the cover receiving groove 210. Thus, when the upper surface of the first reinforcing rib 231 abuts against the lower surface of the cover edge 220 of the upper cover 200, the upper surfaces of the four stacking blocks 240 abut against the bottom of the groove of the upper cover 200, simultaneously providing support. The main advantage of this design is that during the manufacturing process, when the covers 200 need to be stored separately, they can be stacked individually, thus saving space.

[0052] The cover sidewall 250 is also provided with a plurality of second reinforcing ribs 253. The second reinforcing ribs 253 are arranged vertically to connect the upper surface of the cover sidewall 250 and the cover edge 220. The plurality of second reinforcing ribs 253 are spaced apart along the length of the cover 200. The second reinforcing ribs 253 mainly serve a reinforcing function and do not require support. Therefore, the top of the second reinforcing ribs 253 is lower than the first horizontal plane.

[0053] In summary, this utility model embodiment provides a military multi-overlapping packaging box 10, including a detachably connected box body 100 and a lid 200. The upper surface of the box body 100 is recessed inward to form a box body receiving groove 111, and the lower surface of the lid 200 is recessed inward to form a lid receiving groove 210, which can be used to accommodate items and increase storage space. Four support pillars 150 are protruding from the lower surface of the box body 100, located at the four corners of the lower surface of the box body 100; a slot 151 for forklift insertion is formed between two support pillars 150; the lower surface of each support pillar 150 is recessed inward to form a stacking groove 152, and the four stacking grooves 152 are symmetrically arranged; the upper surface of the lid 200 is provided with four stacking blocks 240 corresponding to the four stacking grooves 152. The stacking grooves 152 and stacking blocks 240 facilitate the stacking of the military multi-overlapping packaging box, increasing stacking stability. The design of the slots 151 facilitates transport with a forklift.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
