Description

TECHNICAL FIELD

[0001] The present application relates to a turnover box structure, in particular to an inner buckle top and bottom cover cigarette tow box. BACKGROUND

[0002] The filter tip refers to the upper half of the cigarette, which is a tool specially designed for smokers, which can reduce the smoke, tar and suspended particles at the entrance during smoking. The three main functions of the cigarette filter tip include direct interception, inertial compression and diffusion deposition. With the development of science and technology, the types of filter tips have also changed a lot, and acetate tow is widely used in filter tips.

[0003] When the traditional raw materials are turned over, they are usually packaged and transported from the folding paper box structure, which can be opened at the top. However, in order to improve the turnover efficiency of the materials, the volume of the box needs to be increased to accommodate more tow in a single transportation.

[0004] However, the larger volume of the box brings the problem of inconvenient taking and placing. In the prior art, the Chinese utility model patent with the application number "202121760873.4" discloses a full-corrugated paper collective packaging box with a similar structure. The top and bottom cover box can solve the problem of convenient opening and volume coexistence to a certain extent, but still has the following problems:

[0005] First, the cigarette tow is thin. Once the top and bottom cover box is enlarged, it is easy to deform at the corner and side position after loading a certain amount of goods, resulting in a gap, which causes the tow to leak out or dust and impurities to enter. For the tobacco production link, it is an unacceptable turnover problem.

[0006] Second, the upper and lower covers of the existing box are external, and when the boxes are stacked, they are easy to scratch, causing damage.

[0007] Third, if the upper and lower covers of the current box are internal, the lower cover is easy to come off during assembly (before packing), which affects the packing. SUMMARY

DETAILED DESCRIPTION

[0046] The specific embodiments are merely an explanation of the present application, which is not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution as long as they are within the scope of the claims of the present application after reading the specification.

[0047] Embodiments:

[0048] As Figure 1 Disclosed is a baling state of a silk bundle box for inner buckle top and bottom cover tobacco, wherein the inner buckle refers to that the inner cover 2 is arranged on the inner side of the plate, that is, the inner cover 2 serves as the top cover and the bottom cover in the top and bottom cover, and is covered on the top and the bottom of the surrounding plate 1, so that the inner cover 2 is mirror image arranged in the height direction of the surrounding plate 1, Figure 2 is an exploded view of the silk bundle box for inner buckle top and bottom cover tobacco, which includes an inner cover 2, a surrounding plate 1 and a lining plate 11.

[0049] As Figure 1 and Figure 2 As shown, the surrounding plate 1 extends in the height direction and is closed in the horizontal direction, that is, the surrounding plate 1 is a long rectangular parallelepiped with an upper and lower opening formed after being bent four times, and the surrounding plate 1 can be closed in a side overlapping manner or in a bending position hot-pressing integrated manner according to the use requirement, the former is convenient to connect, and the latter occupies less space for recycling and saves materials.

[0050] As Figure 2 shown, in order to avoid direct contact of the silk bundle with the inner side of the inner cover 2, the inner side of the inner cover 2 is provided with a lining plate 11, as Figure 4 shown, Figure 4 is a die drawing of the inner cover 2, that is, the inner cover 2 is formed by die cutting through an S-shaped plastic hollow plate, which has better structural strength and bending resistance, the periphery of the inner cover 2, that is, the long side position of the inner cover 2 is provided with a long side side plate 21, and the wide side position of the inner cover 2 is provided with a wide side side plate 22, and the long side side plate 21 and the inner cover 2 are bent up at the dotted line position, and the wide side side plate 22 and the inner cover 2 are also bent up at the dotted line position.

[0051] The long side side plate 21 and the wide side side plate 22 are provided with structures for connection, sealing and improving friction, including a connection unfolding structure, an arc corner sealing structure, a side sealing structure and an extrusion deformation abutting structure, the long side side plate 21, the wide side side plate 22, the connection unfolding structure, the arc corner sealing structure, the side sealing structure and the extrusion deformation abutting structure are integrally cut and formed by a plastic hollow plate, and the side sealing structure is extrusion formed or hot-pressing formed.

[0052] As Figures 3 to 8As shown, the connecting expansion structure plays a role of connecting the long side side plate 21 and the wide side side plate 22, which includes the clamping block 32 arranged at the length direction of the wide side side plate 22, and the clamping hole 31 arranged at the length direction of the long side side plate 21. The clamping hole 31 is horizontally arranged and extended, and is a straight cut hole. The clamping hole 31 is fixed to the clamping block 32 by deforming to improve the friction force, and at the same time, as shown in Figure 6 and Figure 7 As shown, the clamping block 32 can move between the length direction of the clamping hole 31, so as to realize the retraction and expansion between the wide side side plate 22 and the long side side plate 21, that is, the clamping hole 31 and the clamping groove form a moving area for the long side side plate 21 and the wide side side plate 22 to expand outward along the horizontal direction in the connected state.

[0053] As shown, Figure 4 The specific structure of the clamping block 32 and the moving area is that the upper surface of the clamping block 32 is provided with a first inclined section 33, a second inclined section 34 and a horizontal section 35. The horizontal section 35 is arranged at the outer end of the clamping block 32. One end of the first inclined section 33 is connected with the end of the horizontal section 35. The other end of the first inclined section 33 extends downward and is connected with one end of the second inclined section 34. The other end of the second inclined section 34 extends upward and is connected with the top of the wide side side plate 22. The moving area is surrounded by the extension lines of the first inclined section 33, the second inclined section 34 and the horizontal section 35. In order to avoid scratching the bottom of the clamping block 32, the bottom of the clamping block 32 is provided with an upward inclined third inclined section 36. When the wide side side plate 22 expands outward, the second inclined section 34 can rotate to the horizontal state. The top of the long side side plate 21 at the length direction is inclined downward to form a fourth inclined section 211, so as to rotate the wide side side plate 22 inward.

[0054] As shown, Figures 4 to 10As shown, when the inner cover 2 is installed on the surrounding panel 1, the wide side panel 22 and the long side panel 21 need to deform inward (especially at the corners). After installation, the wide side panel 22 and the long side panel 21 need to open outward to lock the inner side of the surrounding panel 1. The above problem is solved by setting an arc-angle sealing structure. The arc-angle sealing structure includes a first bending section 41 and a second bending section 42 set between the wide side panel 22 and the locking block 32. After the long side panel 21 and the wide side panel 22 are unfolded outward in the horizontal direction, the upper surfaces of the first bending section 41 and the second bending section 42 are stretched outward to fit against the inner side of the surrounding panel 1. Because a fourth oblique section 211 is provided, the first bending section 41 and the second bending section 42 can retract inward. The structure formed by the first bending section 41 and the second bending section 42 is as follows. The arc-angle sealing structure also includes a first unfolding mark 4. 3. Bending line 44 and second unfolding line 45. The first unfolding line 43 and the second unfolding line 45 are formed by hot pressing and have a small width (because the bending angle is small), while the bending line 44 is formed by hot pressing and has a larger width. The bending line 44 is located between the wide side plate 22 and the locking block 32. The bending line 44 extends along the height direction of the locking block 32. The first unfolding line 43 and the second unfolding line 45 are located on both sides of the horizontal direction of the bending line 44. The bottom of the first unfolding line 43 and the second unfolding line 45 extends to the lower part of the bending line 44. The upper part of the first unfolding line 43 and the second unfolding line 45 extends upward at an angle. The first unfolding line 43 is located on the locking block 32, and the second unfolding line 45 is located on the wide side plate 22. The first bending segment 41 is surrounded by the first unfolding line 43 and the bending line 44, and the second bending segment 42 is surrounded by the second unfolding line 45 and the bending line 44.

[0055] like Figure 6 As shown, the width of the bending mark 44 is 5-20mm, and in this embodiment it is 15mm. The width of the first unfolding mark 43 and the second unfolding mark 45 is one-tenth to one-fifth of the width of the bending mark 44. The ends of the first unfolding mark 43 and the second unfolding mark 45 extend to the sealing protrusion 51. Since the bending mark 44 is relatively wide, the ends of the first unfolding mark 43 and the second unfolding mark 45 are directly connected to the lower middle part of the bending mark 44, which improves the structural strength of the bottom of the corner position.

[0056] like Figure 5 , Figure 7 and Figure 8As shown, in order to ensure the friction between the inner cover 2 and the surrounding plate 1, the side sealing structure includes a sealing protrusion 51 arranged on the outer surface of the wide side plate 22 and the long side plate 21, the sealing protrusion 51 extends along the length direction of the wide side plate 22 and the long side plate 21, and the sealing protrusion 51 abuts against the inner side of the surrounding plate 1. The side sealing structure further includes an abutting groove 65 arranged on the other side of the sealing protrusion 51 away from the wide side plate 22, the abutting groove 65 corresponds to the end of the abutting block 61, the longitudinal section shape of the abutting groove 65 is arc-shaped, and the abutting groove 65 and the sealing protrusion 51 are formed by one-time extrusion.

[0057] As shown in Figure 7 and Figure 8 shown, in order to avoid the right angle transition between the inner cover 2 and the long side plate 21, and between the inner cover 2 and the wide side plate 22, at least two bending grooves 23 are arranged side by side at the connection position of the long side plate 21 and the wide side plate 22 and the inner cover 2, the bending grooves 23 extend along the length direction of the long side plate 21 or the wide side plate 22, and a reinforcing inclined surface 24 is formed between adjacent bending grooves 23.

[0058] As shown in Figures 4 to 7 in order to avoid the retraction of the sealing protrusion 51, a structure is arranged on the long side plate 21 to push the sealing protrusion 51 outward, the extrusion deformation abutting structure includes an abutting block 61 arranged at the end of the long side plate 21 in the length direction, the abutting block 61 abuts against the inner side of the wide side plate 22 and pushes the sealing protrusion 51 towards the surrounding plate 1, the abutting block 61 includes an upper inclined edge 62, a sharp end 63 and a lower inclined edge 64, the extension line of the upper inclined edge 62 coincides with the fourth inclined section 211, and the sharp end 63 cooperates with the abutting groove 65; as shown in Figure 4 and Figure 5 in the die-cut state, a fifth inclined section 37 is arranged on the third inclined section 36 to match the lower inclined edge 64, so that the abutting block 61 protrudes from the end of the long side plate 21.

[0059] Working principle:

[0060] When the tow is packed in the box, the tow is placed in the box, and the tow has a certain volume and weight. The surrounding plate 1 is deformed outward in the horizontal direction, as shown in Figure 9 in the deformed process, the side of the surrounding plate 1 bulges outward, and the corner position of the inner cover 2 tightens inward, through the arrangement of the first bending section 41 and the second bending section 42, the inner cover 2 deforms inward at the corner position, better matches the corner of the deformed surrounding plate 1, reduces the gap, avoids the outside pollution of the box, and avoids the leakage of the tow. At the same time, during transportation, the abutting block 61 always abuts against the sealing protrusion 51, and under the joint action of the strapping 12, the dust enters is reduced.
