Description
Technical Field
[0001] This utility model relates to the field of turnover box technology, and in particular to a raw tobacco leaf recycling turnover box with an easy-to-fold flap. Background Technology
[0002] The reusable tobacco leaf turnover box is a new type of equipment used for tobacco leaf packaging, transportation, and storage, and has been actively promoted in the tobacco industry in recent years. Compared with traditional packaging materials such as hemp sheets and ropes, the reusable tobacco leaf turnover box achieves the goals of recyclability, reusability, and sustainable development, reducing resource waste. However, the existing turnover box has an unreasonable crease structure between the flap and the side panels, requiring additional force to fold the flap and easily causing misalignment and jamming after folding. This increases the labor intensity of operators and reduces the efficiency of packing and unpacking. Therefore, this utility model proposes a reusable tobacco leaf turnover box with an easy-to-fold flap to solve the aforementioned technical problems. Utility Model Content
[0003] In order to overcome the shortcomings of the technical problems mentioned in the background art, the present invention provides a raw tobacco leaf recycling box that is easy to fold.
[0004] The technical solution is as follows: A reusable container for raw tobacco leaves with an easy-to-fold flap includes long side panels and short side panels, with two long and short side panels alternately arranged. Outer flaps are connected to the upper and lower sides of the long side panels, and inner flaps are connected to the upper and lower sides of the short side panels. The long side panels, short side panels, outer flaps, and inner flaps are integrally formed. A first crease is provided at the connection between the long side panel and the outer flap, a second crease is provided at the connection between the long side panel and the short side panel, and a third crease is provided at the connection between the short side panel and the inner flap. Folding is performed according to the first, second, and third creases, and then seamless welding technology is used to connect the outermost long and short side panels to form a reusable container. The distance between the first creases on the same long side panel is greater than the distance between the third creases on the same short side panel. The inner flap has symmetrically arranged corner treatment areas, and the first and third creases are "V"-shaped or "W"-shaped creases.
[0005] More preferably, the corner treatment area is specifically treated by chamfering or rounding.
[0006] More preferably, both the long and short side plates are provided with through holes, which are racetrack-shaped, and handle covers with similar shapes to the through holes are installed on the through holes.
[0007] More preferably, a first groove is symmetrically provided on the side of the outer flap that is in the same folding direction as the first crease, and a male hook and loop fastener is installed in the first groove. A second groove is symmetrically provided on the side of the inner flap that is in the opposite folding direction to the third crease, and a female hook and loop fastener that mates with the male hook and loop fastener is installed in the second groove. The male and female hook and loop fasteners can stick to each other to achieve a stable closure of the outer flap and the inner flap.
[0008] More preferably, a nut is fixed to the outer flap, and the male hook and loop fastener is installed on the nut by a screw. At the same time, the side of the male hook and loop fastener that contacts the outer flap is coated with glue to enhance the stability of the connection. The connection method between the female hook and loop fastener and the inner flap is the same as that of the male hook and loop fastener.
[0009] More preferably, one of the long side panels has three first buckle slots arranged in a "U" shape. A first connecting plate is slidably connected within the first buckle slot. One end of the first connecting plate is connected to a first inverted buckle plate, and the other end of the first connecting plate is connected to a transparent film. The first inverted buckle plate is inverted and placed in the first buckle slot. The first connecting plate, the first inverted buckle plate, and the transparent film form a storage bag for easy placement of sticky notes. The storage bag has symmetrical notches for easy removal of sticky notes. A second buckle slot is provided on the long side panel, arranged in an "U" shape with the first buckle slot. A second connecting plate is slidably connected within the second buckle slot. One end of the second connecting plate is connected to a second inverted buckle plate, and the other end of the second connecting plate is connected to a covering film. Both the second inverted buckle plate and the covering film are inverted and placed in the second buckle slot. The covering film has a fourth crease, and the side of the covering film closest to the storage bag can be folded.
[0010] This utility model has the following advantages: It includes an outer flap, an inner flap, and short side plates. The distance between the first creases on the same long side plate is greater than the distance between the third creases on the same short side plate. This is to accommodate the closing logic of the outer and inner flaps, avoiding interference and improving operational smoothness. If the operator accidentally folds the outer flap first and then the inner flap, the outer flap may lift the inner flap, causing them to press against each other during folding, thus hindering operation. The operator's closing action may be jerky, and the operator will feel resistance when closing the lid. This can guide the operator to fold the inner and outer flaps in the correct way. The first and third creases are "V" shaped creases or "W" shaped creases. This special cross-sectional shape concentrates stress, so that the outer and inner flaps can bend in the direction of the creases when folding. The "V" shaped crease guides the folding direction through the acute-angled groove, while the "W" shaped crease disperses stress through the double groove structure. Both shapes can improve the smoothness of folding and the durability after repeated folding. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0019] As described in the background section, the existing technology has shortcomings. In order to solve the problem that the crease structure between the flap and the side plate of the existing turnover box is unreasonable, which leads to the need for additional force when folding the flap, and the phenomenon of misalignment and jamming after folding, which increases the labor intensity of operators and reduces the efficiency of packing and unpacking, this application proposes a tobacco leaf recycling turnover box that is easy to fold the flap.
[0020] Please see Figures 1-6A reusable tobacco leaf recycling box with easily foldable flaps includes a long side plate 101 and a short side plate 201. Two long side plates 101 and 201 are alternately arranged, connected sequentially in the order of long side plate 101, short side plate 201, long side plate 101, and short side plate 201. Outer flaps 102 are connected to the upper and lower sides of the long side plate 101, and inner flaps 202 are connected to the upper and lower sides of the short side plate 201. The long side plate 101, short side plate 201, outer flaps 102, and inner flaps 202 are integrally formed. This integral forming reduces damage caused by weak welding or material fatigue at the joints, extending the service life of the recycling box. A first crease 301 is provided at the connection between the long side plate 101 and the outer flap 102. A second crease 302 is provided at the connection between the short side plate 201 and the inner flap 202, and a third crease 303 is provided at the connection between the short side plate 201 and the inner flap 202. Folding is performed according to the creases 301, 302, and 303. Then, seamless welding technology is used to connect the outermost long side plate 101 and the short side plate 201 to form a turnover box. The seamless welding technology is specifically ultrasonic welding technology, which is existing technology. Folding is performed according to the creases 301, 302, and 303. After folding, seamless welding technology is used to connect the outermost long side plate 101 and the short side plate 201 to form a complete turnover box. The same long side plate 101... The distance between the first creases 301 on the 01 is greater than the distance between the third creases 303 on the same short side plate 201. This is to accommodate the closing logic of the outer flap 102 and the inner flap 202, i.e., folding the inner flap 202 first and then folding the outer flap 102, avoiding interference and improving the smoothness of operation. However, if the operator accidentally folds the outer flap 102 first and then the inner flap 202, the outer flap 102 will lift up the inner flap 202, causing the outer flap 102 and the inner flap 202 to squeeze each other during folding, resulting in a stuttering closing action and resistance for the operator. This guides the operator to close the inner flap 202 and the outer flap 202 in the correct way. The inner flap 202 is symmetrically provided with corner treatment areas, which are specifically treated by chamfering or rounding. By removing the sharp edges, the frictional resistance between the inner flap 202 and the outer flap 102 is reduced when the flap is folded, and the edges are prevented from scratching the smoke or bumping into the operator. The first crease 301 and the third crease 303 are "V" shaped creases or "W" shaped creases. By using the special cross-sectional shape to concentrate stress, the outer flap 102 and the inner flap 202 can bend in a directional manner along the crease when folding. The "V" shaped crease guides the folding direction through the acute-angled groove, while the "W" shaped crease disperses stress through the double groove structure. Both shapes can improve the smoothness of folding and the durability after repeated folding.
[0021] Furthermore, both the long side plate 101 and the short side plate 201 are provided with through holes 1013, which are racetrack-shaped. A handle cover 401 with a similar shape to the through hole 1013 is installed on the through hole 1013. The racetrack-shaped through hole 1013 is adapted to the hand grip posture. The handle cover 401 matches the shape of the through hole 1013, providing operators with a stable grip point, thereby enabling them to complete loading, unloading, stacking and other operations more effortlessly and improving logistics turnover efficiency.
[0022] Furthermore, the outer flap 102 has symmetrically arranged first grooves 1021 on the side where it folds in the same direction as the first crease 301. A male hook and loop fastener 501 is installed in the first groove 1021. The inner flap 202 has symmetrically arranged second grooves 2021 on the side where it folds in the opposite direction to the third crease 303. A female hook and loop fastener 502 that mates with the male hook and loop fastener 501 is installed in the second groove 2021. The male hook and loop fastener 501 and the female hook and loop fastener 502 can adhere to each other, achieving a stable closure of the outer flap 102 and the inner flap 202. A nut is fixedly connected to the outer flap 102. The male hook and loop fastener 501 is mounted on the nut by a screw. Glue is applied to the side of the male hook and loop fastener 501 that contacts the outer flap 102 to enhance the stability of the connection. The female hook and loop fastener 502 is connected to the inner flap 202 in the same way as the male hook and loop fastener 501, i.e., a nut is fixed to the inner flap 202, and the female hook and loop fastener 502 is mounted on the nut by a screw. Glue is also applied to the side of the female hook and loop fastener 502 that contacts the inner flap 202. This ensures that the male hook and loop fastener 501 and the female hook and loop fastener 502 will not fall off during repeated opening and closing of the turnover box, maintaining a stable connection. Therefore, when the turnover box needs to be closed, first fold the inner flap 202 inward along the third fold 303, and then fold the outer flap 102 inward along the first fold 301. At this time, the male Velcro 501 in the first groove 1021 on the outer flap 102 will be precisely aligned with the female Velcro 502 in the second groove 2021 on the inner flap 202. Since the male and female sides of the Velcro have the characteristic of interlocking, when the two come close to each other, the small hooks on the male Velcro 501 will hook the fine fibers on the female Velcro 502, thereby achieving a stable closure of the outer flap 102 and the inner flap 202. This makes the opening and closing operation more convenient and improves the efficiency of the turnover box.
[0023] Furthermore, one of the long side panels 101 is provided with three first buckle slots 1011 arranged in a "U" shape. A first connecting plate 601 is slidably connected within the first buckle slot 1011. One end of the first connecting plate 601 is connected to a first inverted buckle plate 602, and the other end of the first connecting plate 601 is connected to a transparent film 603. The first inverted buckle plate 602 is inverted at the first buckle slot 1011, leaving only a gap between the transparent film 603 and the long side panel 101 for inserting a sticky note. The first connecting plate 601, the first inverted buckle plate 602, and the transparent film 603 form a storage bag for easy placement of sticky notes. The storage bag is symmetrically provided with notches 6031 for easy removal of sticky notes. Thus, sticky notes for recording tobacco leaf information can be inserted, and the notches 6031 on the storage bag facilitate finger insertion and removal. The sticky note uses a first snap-on groove 1011, a first connecting plate 601, and a first inverted snap-on plate 602. When the transparent film 603 is damaged, it can be easily replaced. A second snap-on groove 1012 is provided on the long side plate 101. The second snap-on groove 1012 and the first snap-on groove 1011 are arranged in an "U" shape. A second connecting plate 605 is slidably connected in the second snap-on groove 1012. One end of the second connecting plate 605 is connected to a second inverted snap-on plate 604, and the other end of the second connecting plate 605 is connected to a covering film 606. Both the second inverted snap-on plate 604 and the covering film 606 are inverted and snapped onto the second snap-on groove 1012. A fourth crease 6061 is provided on the covering film 606. The side of the covering film 606 near the storage bag can be folded, so that it can cover the outside of the storage bag, forming protection for the sticky note and preventing the sticky note from falling out.
[0024] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
