[0032] Reference below Figures 1 to 8 The invention discloses a double-leaf packaging box according to an embodiment of the invention.

[0033] like Figures 1 to 3 As shown, according to the embodiment of the utility model, the double-opening packaging box includes an outer box, and the outer box includes: a first box body 100 and a second box body 200; the first box body 100 is provided with an elastic part 111 with a protrusion 1111; the second box body 200 and the first box body 100 are provided with an opening on the side close to each other, and a first accommodating cavity is formed together with the first box body 100, and the second box body 200 is provided with a first matching slot 211 on the side opposite to the elastic part 111; wherein the elastic part 111 has an elastic force inserted into the first slot 211 so that the first box body 100 and the second box body 200 can be connected to each other.

[0034] It can be understood that this double-opening packaging box includes an outer box, which includes a first box body 100 and a second box body 200 that can be opened or installed in pairs. Specifically, a side of the first box body 100 opposite to the second box body 200 is provided with an elastic portion 111 with a protrusion 1111; a side of the second box body 200 opposite to the first box body 100 is correspondingly provided with a first slot 211, and the first slot 211 is adapted to the elastic portion 111. When the first box body 100 and the second box body 200 are installed in pairs, the elastic portion 111 can be It is elastically deformed and accommodated in the first slot 211, thereby realizing the connection between the first box body 100 and the second box body 200. A first accommodating cavity is formed between the first box body 100 and the second box body 200, which can be used to accommodate items; and when the first box body 100 and the second box body 200 are opened, the elastic part 111 can be pulled out from the first slot 211, thereby realizing the separation of the first box body 100 and the second box body 200, and the operation is convenient; therefore, the double-opening packaging box of the present application is easy to open and close, and the visual effect is novel.

[0035] It is understandable that the elastic portion 111 includes two adjacent protrusions 1111, and the opening of the first slot 211 is smaller than the size of the interior of the first slot 211, so that the two protrusions 1111 can be elastically deformed and approach each other when sliding into the first slot 211, so as to tighten the slot wall of the first slot 211. Figures 1 to 3 As shown, in this embodiment, the elastic part 111 includes two adjacent protrusions 1111. Since the size of the opening of the first slot 211 is smaller than the interior of the first slot 211, the two protrusions 1111 will be elastically deformed due to the compression of the side wall of the opening of the first slot 211 during the process of being inserted into the first slot 211, and then accommodated in the first slot 211, and the first slot 211 is tightened without being separated, thereby achieving the connection between the first box body 100 and the second box body 200. During the opening process, when the two protrusions 1111 slide out from the interior of the first slot 211 to the outside of the opening, the two protrusions 1111 will first approach each other under the compression of the side wall of the opening, and then slide out of the opening, thereby achieving the separation of the first box body 100 and the second box body 200.

[0036] It should be understood that, in addition to the present embodiment, in which the elastic portion 111 can be two adjacent protrusions 1111, in some other embodiments, the elastic portion 111 can also be a deformable spring sheet, which can undergo elastic deformation during the process of being inserted into the first slot 211, thereby tightening the first slot 211, and then deform again when opening, thereby being pulled out.

[0037] It is understandable that an inner box 300 is also included, and the inner box 300 is arranged in the first accommodating cavity in the outer box, and a second accommodating cavity for accommodating items is formed inside the inner box 300, and the front side of the inner box 300 is open; wherein, when the first box body 100 and the second box body 200 are opened, the opening of the inner box 300 can be exposed, so as to take and put items. Figures 1 to 4 As shown, in the present embodiment, the double-open packaging box further includes an inner box 300, which is located in the first accommodating cavity, and a second accommodating cavity is formed inside the inner box 300, and the second accommodating cavity can be used to accommodate items. The front side of the inner box 300 is open, so when the first box body 100 and the second box body 200 of the outer box are opened, the items in the inner box 300 can be exposed and taken out.

[0038] It can be understood that the first plug board 110 and the second plug board 210 are fixedly disposed on the opposite inner sides of the first box body 100 and the second box body 200, respectively, the elastic portion 111 is disposed on the first plug board 110, the first slot 211 is disposed on the second plug board 210, the rear portion of the inner box 300 is the rear plate 310, and the rear plate 310 has a second slot 320 formed inside thereof that runs through the left and right sides of the inner box 300 for the first plug board 110 and the second plug board 210 to be inserted, and the thickness of the first plug board 110 and the second plug board 210 are both adapted to the second slot 320. For example, Figures 1 to 6As shown, in this embodiment, the first box body 100 and the second box body 200 are opened or installed in a pair along the left and right directions, and the first plug plate 110 and the second plug plate 210 are respectively provided on the opposite inner sides of the first box body 100 and the second box body 200, and the first plug plate 110 is provided with an elastic portion 111, and the second plug plate 210 is provided with a first slot 211, and the rear plate 310 of the inner box is provided with a second slot 320, and the second slot 320 runs through the left and right sides of the rear plate 310, and the first plug plate 110 and the second plug plate 210 are inserted into the second slot 320. Therefore, in the process of opening the first box body 100 and the second box body 200, the elastic portion 111 of the first plug plate 110 is separated from the second plug plate 111. The first slot 211 of the second plug plate 210, and the first plug plate 110 and the second plug plate 210 slide in the second slot 320 along the left and right directions respectively; when the outer box is installed, the first plug plate 110 slides to the right in the second slot 320, and the second plug plate 210 moves to the left in the second slot 320 until the elastic portion 111 is inserted into the first slot 211, and because the thickness of the first plug plate 110 and the second plug plate 210 is adapted to the second slot 320, the tightness of the connection between the inner box 300 and the outer box is improved, and the inner box 300 and the outer box are prevented from shaking back and forth during the opening and closing process, thereby improving the stability during the opening and closing process.

[0039] It should be understood that, in addition to the present embodiment, in which the elastic portion 111 and the second plug-in plate 210 provided with the first slot 211 can be inserted into the rear plate 310 of the inner box 300, in some other embodiments, the first slot 211 can also be designed to be provided in the second rear plate at the rear of the second box body 200, so that the elastic portion 111 can also be inserted into the first slot 211 of the second box body 200 after elastic deformation.

[0040] It can be understood that the first plug plate 110 and the second plug plate 210 are provided with a first insertion portion 112 and a second insertion portion 212 in an offset manner on both sides thereof, the second plug plate 210 is provided with a first avoidance position 213 corresponding to the first insertion portion 112, and the first plug plate 110 is provided with a second avoidance position 113 corresponding to the second insertion portion 212; wherein, when the first box body 100 and the second box body 200 are close to each other, the first insertion portion 112 is inserted into the first avoidance position 213, and the second insertion portion 212 is inserted into the second avoidance position 113. For example, Figures 1 to 3As shown, in the present embodiment, the first plug board 110 and the second plug board 210 are respectively provided with a first insertion portion 112 and a second insertion portion 212 on opposite sides thereof, the first insertion portion 112 and the second insertion portion 212 are staggered up and down, and the second plug board 210 is provided with a first avoidance position 213 corresponding to the first insertion portion 112, and the first plug board 110 is provided with a second avoidance position 113 corresponding to the second insertion portion 212, so when the elastic portion 111 is inserted into the first slot 211, the first insertion portion 112 is inserted into the first avoidance position 213, and the second insertion portion 212 is inserted into the second avoidance position 113, and the arrangement of the first insertion portion 112 and the second insertion portion 212 can improve the stability of the elastic portion 111 in the process of inserting the first slot 211, and can share the bearing capacity of the position where the elastic portion 111 and the second plug board 210 are provided with the first slot 211, thereby reducing the loss of the elastic portion 111 and the second plug board 210.

[0041] It can be understood that the third plugboard 120 and the fourth plugboard 220 are fixedly disposed on the inner side surfaces opposite to each other of the first box body 100 and the second box body 200, and the third plugboard 120 and the fourth plugboard 220 are staggered up and down, the bottoms of the first box body 100 and the second box body 200 are the first bottom plate and the second bottom plate, and the third plugboard 120, the fourth plugboard 220, the first bottom plate and the second bottom plate are parallel, and the top and / or bottom of the inner box 300 are provided with a third slot 330 and a fourth slot 340 arranged at intervals up and down, the thickness of the third plugboard 120 is adapted to the third slot 330, the thickness of the fourth plugboard 220 is adapted to the fourth slot 340, and the third slot 330 and the fourth slot 340 respectively penetrate the left and right sides of the inner box 300 to allow the third plugboard 120 and the fourth plugboard 220 to be inserted respectively. For example, Figures 7 and 8 As shown, in this embodiment, the inner sides of the first box body 100 and the second box body 200 relative to each other are further provided with a third plugboard 120 and a fourth plugboard 220, respectively. The third plugboard 120 and the fourth plugboard 220 are distributed up and down, and are parallel to the first bottom plate of the first box body 100 and the second bottom plate of the second box body 200. The top of the inner box 300 is the top plate, and the bottom of the inner box 300 is the bottom plate. The top plate and / or the bottom plate are provided with a third slot 330 and a fourth slot 340 arranged at intervals up and down. The third slot 330 runs through the left side of the inner box 300 for the third plugboard 120 is inserted, and the fourth slot 340 runs through the right side of the inner box 300 for the fourth plug board 220 to be inserted. Since the thickness of the third plug board 120 is adapted to the third slot 330, and the thickness of the fourth plug board 220 is adapted to the fourth slot 340, therefore, in the process of opening or installing in pairs, since the third plug board 120 slides along the third slot 330 and the fourth plug board 220 slides along the fourth slot 340, the stability of the inner box 300, the first box body 100 and the second box body 200 in the up and down directions can be improved during the left and right sliding process to avoid up and down shaking.

[0042] It is understandable that a cavity is formed between the left and right sides of the inner box 300 and the outer box, and an air passage 350 is opened through the inner box 300. When the first box body 100 and the second box body 200 are opened or installed oppositely, the air passage 350 connects the cavity with the external air. Figures 7 and 8 As shown, in this embodiment, a cavity is formed between the left side of the inner box 300 and the first box body 100, and between the right side of the inner box 300 and the second box body 200. An air passage 350 connecting the cavity is opened through the inner box 300. When the outer box is opened or installed, the air passage 350 connects the external air and the cavity, thereby reducing the resistance of the air pressure and facilitating the opening or installation.

[0043] It can be understood that the air channel 350 runs through the left and right sides of the inner box 300, and the two ends of the air channel 350 are respectively the first air hole 351 and the second air hole 352, and the middle of the top plate or the bottom plate of the inner box 300 is provided with a third air hole 353, and the third air hole 353 is connected to the air channel 350. Figures 7 and 8 As shown, in the present embodiment, the air passage 350 passes through the left and right sides of the inner box 300, and passes through the left end of the inner box 300 to form a first air hole 351, and passes through the right end of the inner box 300 to form a second air hole 352. A third air hole 353 connected to the air passage 350 is provided in the middle of the top or bottom of the inner box 300. Therefore, at the moment of opening the outer box, the external air can flow to the first air hole 351 and the second air hole 352 through the third air hole 353, and then flow to the cavities on the left and right sides of the inner box 300, thereby facilitating the opening process; during the assembly process, the first box body and the second box body are constantly approaching and squeezing the gas in the cavities on the left and right sides of the inner box 300, and the gas in the cavity is discharged to the third air hole 353 through the first air hole 351 and the second air hole 352, thereby facilitating the assembly.

[0044] It should be understood that, in addition to the above-mentioned arrangement, the air passage 350 can also be arranged to penetrate the left plate on the left side and the right plate on the right side of the inner box 300, so that the air passage 350 can connect the cavity on the left side of the inner box 300 and the second accommodating cavity, as well as the cavity on the right side of the inner box 300 and the second accommodating cavity, thereby facilitating the reduction of gas resistance during the process of mounting or opening.

[0045] It is understandable that it also includes a first guide structure and a second guide structure, the first guide structure is arranged on the inner side of the outer box, and the second guide structure is arranged on the outer side of the inner box 300, so that the first box body 100 and the second box body 200 can slide linearly along the inner box 300 when they are opened. Figures 2 to 6As shown, in this embodiment, the inner side surfaces of the first box body 100 and the second box body 200 are provided with a first guide structure, and the outer side surface of the inner box 300 is correspondingly provided with a second guide structure, so that the first box body 100 and the second box body 200 can slide in a straight line along the inner box 300 during the process of being assembled or opened, thereby improving the stability of the opening and closing process, as well as the linearity of the sliding.

[0046] It can be understood that the first guide structure is a guide groove 130 provided on the inner side of the first box body 100 and the inner side of the second box body 200, the extension direction of the guide groove 130 is along the opening direction of the outer box, and the guide groove 130 is not arranged through both sides, and the second guide structure is a protrusion 370 provided on the top and / or bottom of the inner box 300, and the protrusion 370 can slide along the guide groove 130. For example, Figures 2 to 6 As shown, in the present embodiment, the first guide structure is a guide groove 130, and the extension direction of the guide groove 130 is consistent with the opening and closing direction of the outer box. The second structure is arranged at the top and / or bottom of the inner box 300, and is a protrusion 370. The protrusion 370 can slide along the guide groove 130, so that the outer box can slide along the inner box 300 to open. Since the guide groove 130 does not penetrate the inner wall of the first box body 100, nor does it penetrate the inner wall of the second box body 200, during the opening process, the outer box and the inner box 300 will not be completely separated, which is also convenient for the next installation.

[0047] Of course, in other embodiments, the guide groove 130 may also be configured to penetrate the inner wall of the outer box.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
