Description

Technical Field

[0001] The invention belongs to the technical field of packaging box structures, and in particular relates to a double-opening bamboo and wooden packaging box. Background Art

[0002] Bamboo and wood packaging boxes refer to packaging boxes that are made of at least part bamboo and wood, with the remainder made of paper. Furthermore, bamboo-wood-paper composite packaging boxes offer the advantages of bamboo and wood, while also reducing weight.

[0003] On the other hand, the double-opening type means that the packaging box has two flip-open door structures, so it can correspond to two different functional areas, such as the material area and the tool area.

[0004] The Chinese utility model patent with patent announcement number CN217171559U and announcement date 2022.08.12 discloses a double-door packaging box, including a box body, and a box lid is integrally formed at the edges of both sides of the top surface of the box body. The top of the box lid is bendably integrally formed with a folding plate, and a slot is provided on the box body. The folding plate is plugged into the inside of the slot. The inside of the box body is slidably connected to a lifting mechanism, and the lifting mechanism is connected to the inner side wall of the box lid through a pulling mechanism. The lifting mechanism includes a lifting plate, a placement slot, a pulley and a slide slot.

[0005] The double-door packaging box in this utility model patent is generally used as follows: grab the handles with both hands, and then pull the box lid from the top surface of the box body to both sides along the two side edges of the top surface of the box body as the center of the circle, so that the folding plate is pulled out from the slot of the box body, and at the same time, the pull rope pulls the lifting plate so that the pulleys on the side walls of the lifting plate can slide in the sliding grooves on the side walls of the box body, so that the lifting plate can slide from the inside of the box body to the top surface of the box body while opening the box lid, so that the objects on the lifting plate can be taken out.

[0006] However, in actual use, the double-door packaging box still has at least the following shortcomings, in other words, which are the technical problems to be solved by the present invention:

[0007] Its double-door structure makes it difficult to open one side alone, so the packaging box lacks the expansion function of being divided into two different functional areas, and the overall usage effect is not good.

[0008] Therefore, in summary, there is an urgent need for a partitioned packaging box with a more flexible double-door structure and which can be opened on one side. Summary of the Invention

[0009] The present invention provides a double-opening bamboo and wooden packaging box. By arranging a tool area lifting plate, a material area slot plate unit, a rotating bamboo wood board unit, a rotating paperboard unit, a fixed side panel unit, and a composite side panel unit on a box body, the following can be achieved: 1. The rotating bamboo wood board unit and the rotating paperboard unit can be opened separately, ensuring that the material area slot plate unit, which is opened and closed relatively frequently, has a lighter lifting weight and a smaller rotation lifting amplitude; 2. The rotating bamboo wood board unit can only be closed first, and then the rotating paperboard unit, so as to avoid large-area wear of the rotating paperboard unit.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problems is: a double-opening bamboo and wood packaging box, the structure of which includes a box body, and also includes a tool area lifting plate arranged on the inner side surface of the box body, a material area slot plate unit arranged in the box body and covering the tool area lifting plate, a rotating bamboo wood board unit arranged on the inner side surface of the box body and used to seal the tool area lifting plate, a rotating paperboard unit arranged on the inner side surface of the box body and used to seal the material area slot plate unit, a fixed side panel unit arranged on the material area slot plate unit and used to support the rotating bamboo wood board unit, and a composite side panel unit arranged on the material area slot plate unit and used to limit the first closure of the rotating bamboo wood board unit by blocking the rotating paperboard unit.

[0011] A further preferred technical solution is that the material area slot plate unit includes a slotted block arranged on the bottom surface of the box body, and a perforated plate arranged on the side of the slotted block and located on the upper surface of the tool area lifting plate.

[0012] A further preferred technical solution is that the rotating bamboo wood board unit includes a fixed shaft arranged on the inner side of the box body and located at one side of the perforated plate, a rotating plate with one end sleeved on the fixed shaft, and a clamping plate arranged at the other end of the rotating plate and used to engage the rotating paperboard unit.

[0013] A further preferred technical solution is that the rotating cardboard unit includes an end fixing plate arranged on the inner side of the box body and located on one side of the slotted block, a bent cover plate arranged on the end fixing plate and used to cover the slotted block, and a relative sliding plate arranged on the bent cover plate and used to engage the clamping plate.

[0014] A further preferred technical solution is that the fixed side plate unit includes a first vertical plate provided on the perforated plate, and a first horizontal plate provided on the first vertical plate and used for supporting the rotating plate.

[0015] A further preferred technical solution is that the fixed side plate unit is bonded to the inner side of the box body.

[0016] A further preferred technical solution is that the composite side panel unit includes a transverse top plate arranged on the perforated plate and used to block and limit the relative sliding plate, a second vertical plate arranged on the transverse top plate, and a second transverse plate arranged on the second vertical plate and used to support the bent cover plate.

[0017] A further preferred technical solution is that the second vertical plate and the second horizontal plate are bonded to the inner side of the box body.

[0018] A further preferred technical solution is that the lateral distance between the second transverse plate and the relatively sliding plate is 0.5-0.8 cm.

[0019] A further preferred technical solution is that the vertical distance between the end fixing plate and the slotted block is less than 0.1 cm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-9 As shown, a double-opening bamboo and wooden packaging box has a structure including a box body 11, and also includes a tool area lifting plate 1 arranged on the inner side surface of the box body 11, a material area slot plate unit 2 arranged in the box body 11 and covering the tool area lifting plate 1, a rotating bamboo wood board unit 3 arranged on the inner side surface of the box body 11 and used to seal the tool area lifting plate 1, a rotating cardboard unit 4 arranged on the inner side surface of the box body 11 and used to seal the material area slot plate unit 2, a fixed side panel unit 5 arranged on the material area slot plate unit 2 and used to support the rotating bamboo wood board unit 3, and a composite side panel unit 6 arranged on the material area slot plate unit 2 and used to limit the first closing of the rotating bamboo wood board unit 3 by blocking the rotating cardboard unit 4.

[0036] In this embodiment, the packaging box can be a tea box or a moon cake box. In the former case, tea bags are placed in the material area and bamboo clips and spoons are placed in the tool area. In the latter case, moon cake bags are placed in the material area and metal or plastic knives and forks are placed in the tool area.

[0037] Obviously, the material area needs to be opened and closed relatively frequently, while bamboo clips, bamboo spoons, knives and forks do not need to be used every time. Therefore, the material of the rotating cardboard unit 4 is cardboard, which is relatively light, and the material of the rotating bamboo wood board unit 3 is bamboo, which is relatively heavy. Ultimately, the packaging box has both visual grade and portability.

[0038] In addition, tea bags, moon cake bags, etc. are relatively large in size, while bamboo clips, bamboo spoons, knives and forks are relatively small. This is the purpose of raising the tool area lifting plate 1 appropriately to avoid the need to reach in with hands to take and put knives and forks, which is very practical.

[0039] Finally, the rotating bamboo board unit 3 and the rotating paperboard unit 4 essentially do not affect the sealing effect of the packaging box whether they are closed first or later. Figure 8 As shown, the rotating bamboo wood board unit 3 will create a large wear area on the rotating paperboard unit 4, which is not allowed for packaging boxes with high aesthetic requirements.

[0040] Therefore, on the contrary, the rotating bamboo wood board unit 3 in this embodiment is closed first, and its material is bamboo wood, and the cardboard can hardly cause scratches on the bamboo wood, and finally as shown in the attached figure, Figure 9 As shown, the rotating paperboard unit 4 only causes a small wear chamfer d, which is quite necessary and relatively aesthetically pleasing.

[0041] Correspondingly, the word "composite" of the composite side panel unit 6 refers to functional composite, that is, the composite side panel unit 6 can not only vertically support the rotating cardboard unit 4, but also laterally support the rotating cardboard unit 4. As long as the rotating cardboard unit 4 cannot yield and bend laterally, the rotating bamboo wood board unit 3 cannot be rotated and closed, which also limits the rotating bamboo wood board unit 3 to be closed first.

[0042] The material area slot plate unit 2 includes a slotted block 201 provided on the inner bottom surface of the box body 11 , and a perforated plate 202 provided on the side of the slotted block 201 and located on the upper surface of the tool area lifting plate 1 .

[0043] In this embodiment, the material of the material area slot plate unit 2 is the existing common foam material. The "slot" of the slot block 201 is used to place tea bags and moon cake bags, and the "hole" of the perforated plate 202 is used to place clips, knives and forks, etc.

[0044] The slotted block 201 and the perforated plate 202 are integrally formed, and their upper surfaces are flush and of equal width, with the former being thicker than the latter.

[0045] The rotating bamboo wood board unit 3 includes a fixed shaft 301 arranged on the inner side of the box body 11 and located at one side of the perforated plate 202, a rotating plate 302 with one end sleeved on the fixed shaft 301, and a clamping plate 303 arranged at the other end of the rotating plate 302 and used to engage the rotating paperboard unit 4.

[0046] In this embodiment, the rotating bamboo board unit 3 and the rotating cardboard unit 4 do not press the material area slot plate unit 2 to avoid unsightly indentations on the upper surface of the latter. Therefore, the rotation end point of the rotating plate 302 is the fixed side plate unit 5.

[0047] Among them, the rotating plate 302 and the clamping plate 303 are both "L-shaped", and the hole in the opening plate 202 plus the hinged connection method of the fixed shaft 301 can also be replaced by a circular shaft protruding from the side of the former, and a circular slot is opened on the inner side of the box body 11.

[0048] The rotating cardboard unit 4 includes an end fixing plate 401 arranged on the inner side surface of the box body 11 and located on one side of the slotted block 201, a bent cover plate 402 arranged on the end fixing plate 401 and used to cover the slotted block 201, and a relative sliding plate 403 arranged on the bent cover plate 402 and used to engage the clamping plate 303.

[0049] In this embodiment, the end fixing plate 401, the bending cover plate 402, and the relative sliding plate 403 are all made of cardboard, but soft paper is provided between adjacent ones to ensure that the latter two can be flexibly folded.

[0050] The reason why the rotating bamboo wood board unit 3 and the rotating paperboard unit 4 are not easy to rotate open spontaneously is due to at least the following four points:

[0051] 1. The packaging box is prohibited from being turned upside down;

[0052] 2. The lengths of the bent cover plate 402 and the rotating plate 302 are as large as possible to cover the entire packaging box, and the two are also fully supported and clamped;

[0053] 3. In the absence of external force, the angle between the relative sliding plate 403 and the bent cover plate 402 is 92-95 degrees, so that even if the relative sliding plate 403 is slightly loosened upward, it can still properly support the clamping plate 303;

[0054] 4. The entire rotating bamboo wood board unit 3 and the rotating paperboard unit 4 are wide enough, and the sides of the two in the width direction also appropriately rub against the inner side of the box body 11.

[0055] The fixed side plate unit 5 includes a first vertical plate 501 provided on the perforated plate 202 , and a first horizontal plate 502 provided on the first vertical plate 501 and used to support the rotating plate 302 .

[0056] In this embodiment, the general shape of the fixed side plate unit 5 is "T-shaped", and two "T-shaped" supporting and limiting structures are provided in the box body 11.

[0057] The fixed side plate unit 5 is bonded to the inner side surface of the box body 11 .

[0058] In this embodiment, the material area slot plate unit 2 is glued and fixed, but glue can only be applied on the bottom surface. If glue is applied on the side, when the material area slot plate unit 2 is placed in the box body 11, the glue will be left on the upper part of the inner side of the box body 11 and will be completely ineffective.

[0059] Therefore, the fixed side panel unit 5 is connected to the perforated plate 202 by bending, that is, soft paper with its own crease e is provided to ensure that the fixed side panel unit 5 is bonded later, which can also reinforce the material area slot plate unit 2.

[0060] Therefore, in the end, the main material of the fixed side panel unit 5 is also cardboard, and there is a small section of soft paper between it and the perforated plate 202 to "pull" the material area slot plate unit 2 that may separate upward on the fixed side panel unit 5.

[0061] The composite side panel unit 6 includes a transverse top plate 601 arranged on the perforated plate 202 and used to block and limit the relative sliding plate 403, a second vertical plate 602 arranged on the transverse top plate 601, and a second transverse plate 603 arranged on the second vertical plate 602 and used to support the bent cover plate 402.

[0062] In this embodiment, when the rotating bamboo wood board unit 3 is correctly closed first, as shown in the attached Figure 7 As shown, the relative surface distance between the transverse top plate 601 and the clamping plate 303 is slightly smaller than the thickness of the relative sliding plate 403, so that the relative sliding plate 403 is "squeezed into" the above distance, ensuring that the packaging box is not easily opened accidentally.

[0063] When the rotating bamboo wood board unit 3 is mistakenly closed at the rear, the transverse top plate 601 is the rear supporting portion of the relative sliding plate 403. At this time, if the clamping plate 303 wants to rotate downward and close, it originally wants to push the relative sliding plate 403 inward.

[0064] However, due to the existence of the horizontal top plate 601 and the relatively hard cardboard of the sliding plate 403 itself, the clamping plate 303 cannot be rotated closed.

[0065] In addition, the main material of the composite side panel unit 6 is also cardboard, and 2-3 second vertical panels 602 can be provided because the horizontal top panel 601 and the second horizontal panel 603 themselves are relatively long, significantly longer than the first horizontal panel 502.

[0066] The second vertical plate 602 and the second horizontal plate 603 are bonded to the inner side of the box body 11 .

[0067] In this embodiment, the fold e exists between the second vertical plate 602 and the horizontal top plate 601. In other words, a soft paper connection is provided between the two. The horizontal top plate 601 is fixedly connected to the slotted block 201, and can even be integrally formed, also made of foam material. An excessively long fold e is unnecessary and would increase bending difficulty. After all, the tendency of the material area slot plate unit 2 to shift upward and fall off is relatively small.

[0068] Moreover, after the transverse top plate 601 is fixed on the slotted block 201, it has a more stable "foundation", ensuring that the relative sliding plate 403 is more difficult to be pushed inward, which is more important than limiting the upward displacement and falling off of the material area slot plate unit 2.

[0069] The transverse distance a between the second transverse plate 603 and the relative sliding plate 403 is 0.5-0.8 cm.

[0070] In this embodiment, as shown in the attached Figure 7 As shown, when the rotating cardboard unit 4 is rotated upward to open, the relative sliding plate 403 has a small leftward offset. If the second horizontal plate 603 also tightly supports the upper part of the relative sliding plate 403 laterally, the relative sliding plate 403 must be slightly compressed and deformed when it is rotated upward to open, which is completely unnecessary.

[0071] In other words, this is the purpose of the lateral distance a.

[0072] The vertical distance b between the end fixing plate 401 and the slotted block 201 is less than 0.1 cm.

[0073] In this embodiment, the end fixing plate 401 itself has a certain thickness and is bonded to the inner side of the box body 11, which can also appropriately limit the upward displacement and fall-off of the material area slot plate unit 2. Therefore, this is the purpose of minimizing the vertical distance b.

[0074] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the aforementioned embodiments. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
