Description

Linked assembly structure of accommodating box

This invention is a technology related to a paper container box, which is composed of a single piece of cardboard after cutting and partial pre-gluing. The cardboard can be quickly assembled into a container box with a reinforced structure in a linked manner.

Generally, a foldable container box can be made of a cardboard that is folded and glued together. According to business practice, it will first be assembled into a flat semi-folded state to save stacking space. After being transported to the sales end, it will be assembled into a three-dimensional state by the sales operator at the sales site to accommodate the product.

(Introduction of the basic structure of the paper box and definition of the name) As shown in the first figure (A), the paper board of the above-mentioned known folding storage box has a rectangular bottom plate 91, and a left wall plate 92, a right wall plate 93, a front wall plate 94 and a rear wall plate 95 extending outward from the periphery of the bottom plate 91. Among them, a connecting piece 96 is respectively provided at the four corner ends where the left and right wall plates 92, 93 and the front and rear wall plates 94, 95 intersect, and each connecting piece 96 is respectively provided with an oblique fold 97.

Before use, the paperboards can be assembled into a flat half-folded state for easy storage and unfolding. As shown in the first figure (B), the left and right wall panels 92 and 93 are folded inward and stacked on both sides of the bottom plate 91, and each connecting piece 96 is partially pre-adhered to the front and rear wall panels 94 and 95 with the oblique fold 97 as a dividing line, so as to form a flat half-folded state, so as to facilitate the stacking and storage of multiple half-folded storage boxes.

When in use, as shown in the first figure (C) and (D), the left and right wall panels 92, 93 are unfolded outward and stand upright on both sides of the bottom plate 91 respectively. At this time, the front and rear wall panels 94, 95 can be pulled by partial adhesion of each connecting piece 96, so that the front and rear wall panels 94, 95 stand upright at the same time to assemble into a three-dimensional storage box.

The main body of the above-mentioned storage box is composed of a single paperboard. Although it has the advantages of saving storage space and being convenient to use, if the paperboard is made of a heavier and thicker material, the left and right wall panels 92 and 93 stacked on both sides of the bottom plate 91 are easy to rebound in the half-folded state, affecting the convenience of storage; if the paperboard is made of a lighter and thinner material, the strength of the four wall panels and the bottom plate of the assembled three-dimensional storage box is slightly insufficient, so that the volume and weight of the goods that the storage box can be used for are limited.

In order to overcome the above problems, the inventor has developed a foldable container box and applied for patent approval in many countries, including US10407205B2, CA2977595, EP3412588A1, NZ739197, KR200490644, AU2018100072A4, etc. Its structure is to adhere a reinforcing sheet to the outer edge of each wall panel to strengthen the strength of each wall panel, so that when the container box is made of thinner paperboard, the surrounding wall panels can still maintain structural stability.

After actual implementation of the above-mentioned storage box, it was found that there is still room for reinforcement at the bottom plate position, so the creator of the present invention continues to develop EP3689766A1, CA3038400A1, NZ752238A, CN111498240A, WO2020154825A1, TW I681910 "Pull-type quick-assembly storage box". In addition to the structural characteristics of the aforementioned half-folded assembly state, the storage box body is also provided with a traction support plate. On the one hand, the traction support plate can be used to quickly assemble the paperboard from the half-folded assembly state into a three-dimensional state. On the other hand, the traction support plate can be used to make the three-dimensional storage box have a double-layer bottom plate and a double-layer wall plate, thereby improving the load-bearing strength of the bottom plate.

During the manufacturing of the above-mentioned pull-type container box, the pulling support plate and the paperboard constituting the container box body need to be manufactured separately and then assembled, which results in high manufacturing and assembly costs and possible waste of paperboard materials. Therefore, the present inventors envision that if the pulling support plate and the folding box can be integrally formed of a single paperboard, material waste can be reduced and manufacturing steps and working hours can be saved.

The above concept was specifically experimented by the present creator, and it was found that if the pulling support plate is integrally extended from a single piece of paperboard, then when the three-dimensional storage box is assembled, the two sides of the pulling support plate relative to the intersection of the bottom plate and the left and right wall plates will be pushed outward due to the lack of compression space. At this time, since the left and right wall plates and the bottom plate are fixed in relative position, the two sides of the pulling support plate will be pushed in the opposite direction, causing the pulling support plate to bulge inward relative to the inner side surfaces of the left and right wall plates, and slightly arch upward relative to the top surface of the bottom plate, so that the pulling support plate cannot be smoothly overlapped with the bottom plate and the left and right wall plates of the folding box, causing obstacles in implementation. After continuous research and testing by the author, the above problems were finally overcome.

The purpose of this invention is to provide a linkage assembly structure of a container box, which is composed of a single piece of paperboard, and an inner lining support plate is integrally extended from the left wall plate or the right wall plate, and the inner lining support plate is pre-set with a notch for compression. In addition to still having the function of quickly assembling a container box from a half-folded state, it also has the advantages of reducing the cost of molds and paper materials, reinforcing the strength of the bottom plate and the wall plate, and making the inner lining support plate overlap smoothly after assembly.

To achieve the above purpose, the invention is a linkage assembly structure of a storage box, which is composed of a single piece of paperboard after cutting and folding. The paperboard includes a rectangular bottom plate in a flat unfolded state, and a left wall plate, a right wall plate, a front wall plate and a rear wall plate extending outward from the four edges of the bottom plate respectively. The four corners where the front and rear wall plates intersect with the left and right wall plates are respectively provided with a connecting piece to connect with each other; Wherein the left wall plate integrally extends outward with a rectangular inner lining support plate, and the inner lining support plate includes a left lining plate, a right lining plate and a bottom lining plate between the left and right lining plates. The length and width of the left and right lining plates are roughly the same as those of the left and right wall plates, respectively, and the length and width of the bottom lining plate are roughly the same as those of the bottom plate; The left lining is integrally connected to the left wall plate, and a first fold line is provided at the connection position. An adhesive sheet is integrally extended from the edge of the right lining, and a second fold line is provided between the right lining and the adhesive sheet. The right wall plate is provided with an adhesive area at a position opposite to the adhesive sheet, and the adhesive sheet is bonded and fixed to the adhesive area so that the right lining and the right wall plate are connected to each other; When folded, the front wall and the rear wall are folded inwards and overlapped on a top surface of the bottom plate. Each connecting piece has an inner side surface overlapping the adjacent left and right wall plates, and the inner lining support plate is movably overlapped on the top surface of the bottom plate through the first and second folding lines located on both sides, covering the left wall plate, the right wall plate, the front wall plate, the rear wall plate and the top of the plurality of connecting pieces, thereby forming a half-folded assembly state; The two side edges of the bottom lining are provided with a left fold line and a right fold line at the intersection with the left and right linings, respectively. The left and right fold lines are provided with at least one notch, respectively, so that the left and right fold lines form at least two connecting parts on both sides of the corresponding notch, and the bottom lining is provided with an auxiliary embossing mark parallel to the left and right fold lines at the central position of the width; When assembling from a half-folded state, force is applied to push the left and right wall panels to bend and stand upright relative to the bottom plate, and the front and rear wall panels can be driven to stand upright through the corresponding connecting pieces, and at the same time, the inner lining support plate is pushed to bend from the auxiliary indentation and arch above the top surface of the bottom plate, and then the left and right linings are bent along the left and right fold lines respectively toward the inner side surfaces of the front and rear wall panels, driving the bottom lining to move toward the bottom plate, so that the bottom lining is pressed down and overlapped on the top surface of the bottom plate, and at the same time, the left and right linings are pushed to overlap toward the inner side surfaces of the left and right wall panels respectively; and When the bottom lining is overlapped on the top surface of the bottom plate, the left and right fold lines on both sides thereof generate a deformable and compressible space at the intersection of the two sides of the bottom lining and the left and right linings through the notch and the plurality of connecting parts, so that the left and right linings of the inner lining support plate can be overlapped flatly on the inner side surfaces of the left wall plate and the right wall plate respectively, and the bottom lining is overlapped flatly on the top surface of the bottom plate.

Through the above structure, in addition to the advantages of being easy to store in a half-folded state, quickly assembled from a half-folded state, and having enhanced load-bearing strength through the inner lining support plate, the inner lining support plate is formed by extending outward from the left wall plate as a whole, which can save processing costs and reduce waste of paper materials. After being assembled into a three-dimensional storage box, the inner lining support plate can be evenly overlapped on the left wall plate, the right wall plate and the bottom plate through the notch on the fold line and the compression space formed by multiple connecting parts, thereby improving the refinement of the paper storage box.

This invention provides another linkage assembly structure of a storage box, which is composed of a single piece of paperboard after cutting and folding. The paperboard includes a rectangular bottom plate in a flat unfolded state, and a left wall plate, a right wall plate, a front wall plate and a rear wall plate extending outward from the four sides of the bottom plate.

Each connecting piece has an inner side surface overlapped with the adjacent left and right wall panels, and the inner lining support plate is movably overlapped on the top surface of the bottom panel through the first and second inverted fold lines located on both sides, covering the left wall panel, the right wall panel, the front wall panel, the rear wall panel and the top of the plurality of connecting pieces, so as to form a half-folded assembly state; A left fold line is provided at the intersection of the left lining and the first bottom lining, and a right fold line is provided at the intersection of the right lining and the second bottom lining. At least one notch is provided on the left and right fold lines, so that the left and right fold lines form at least two connecting parts on both sides of the corresponding notch, and An auxiliary embossing mark parallel to the left fold line and the right fold line is provided in the center of the width where the first and second bottom lining sheets are connected to each other; When assembling from a half-folded state, force is applied to push the left and right wall panels to bend and stand upright relative to the bottom plate, and the front and rear wall panels can be driven to stand upright through the corresponding connecting pieces, and at the same time, the inner lining support plate is pushed to bend from the auxiliary indentation and arch above the top surface of the bottom plate, and then the left and right linings are bent along the left and right fold lines toward the inner side surfaces of the front and rear wall panels, driving the first and second bottom linings to move toward the bottom plate, so that the first and second bottom linings are pressed down and overlapped on the top surface of the bottom plate, and at the same time, the left and right linings are pushed to overlap toward the inner side surfaces of the left and right wall panels respectively; and When the first and second bottom lining sheets are overlapped on the top surface of the bottom plate, the left and right fold lines on both sides thereof generate deformable and compressible spaces at the intersections of the two sides of the first and second bottom lining sheets with the left and right lining sheets respectively through the notch and the connecting portion, so that the left and right lining sheets of the inner lining support plate can be overlapped flatly on the inner side surfaces of the left wall plate and the right wall plate respectively, and the first and second bottom lining sheets are overlapped flatly on the top surface of the bottom plate.

Compared to the previous technology, the inner lining support plate of the present invention is integrally extended from the left wall plate, and is cut from a single piece of paperboard together with the bottom plate and multiple wall plates. The inner lining support plate is pre-set with a notch for compression. In addition to allowing the container box to be quickly assembled from a half-folded state to a three-dimensional state, it also has the advantages of reducing mold and paper material costs, reinforcing the strength of the bottom plate and wall plates, and allowing the inner lining support plates to overlap smoothly after assembly.

Based on the technical means of this creation, the following lists the implementation methods suitable for this creation, and illustrates them with diagrams as follows:

For ease of understanding, the front, rear, left, and right described below are all based on the directions in the diagram, and the actual implementation and patent scope are not limited thereto. For example, being arranged on the left side and being arranged on the right side are actually equivalent structures, and it is necessary to explain this first.

Please refer to the second figure, which reveals that the interlocking assembly structure of the creative storage box is composed of a single piece of paperboard that is cut and folded. The paperboard 100 includes a rectangular bottom plate 11 in a flat unfolded state, and a left wall plate 12, a right wall plate 13, a front wall plate 14 and a rear wall plate 15 extending outward from the four edges of the bottom plate 11, wherein the four corner ends of the front and rear wall plates 14, 15 intersecting with the left and right wall plates 12, 13 are respectively provided with a connecting piece 16 to connect with each other.

One of the characteristics of the present invention is that the left wall panel 12 integrally extends outwardly to have an inner lining support plate 20 which is generally rectangular, and the inner lining support plate 20 includes a bottom lining plate 21, and a left lining plate 22 and a right lining plate 23 which integrally extend to the left and right sides from the bottom lining plate 21, respectively. The left lining plate 22 is integrally connected to the left wall panel 12, and the length and width of the left and right lining plates 22, 23 are substantially the same as those of the left and right wall panels 12, 13, respectively, and the length and width of the bottom lining plate 21 are substantially the same as those of the bottom plate 11.

The bottom liner 21 has an auxiliary embossing mark 31 at the center of the width, and a left fold line 32 and a right fold line 33 are respectively provided at the intersection of the two side edges of the bottom liner 21 with the left and right liner 22, 23, and the left fold line 32, the right fold line 33 and the auxiliary embossing mark 31 are parallel to each other.

In addition, a first fold line 34 is provided at the intersection where the left lining 22 is integrally connected to the left wall panel 12, an adhesive sheet 24 is integrally extended from the edge of the right lining 23, a second fold line 35 is provided between the right lining 23 and the adhesive sheet 24, and an adhesive area 25 is provided at a position of the right wall panel 13 relative to the adhesive sheet 24, and the right lining 23 and the right wall panel 13 can be connected to each other by bonding the adhesive sheet 24 to the adhesive area 25.

The third to fifth figures show the invention of pre-assembling the flat paperboard into a half-folded state. As shown in the third and fourth figures, when the paperboard 100 begins to be folded, the user can fold the front wall 14 and the rear wall 15 inwards and overlap them on the top surface 110 of the bottom plate 11, and the inner side surface 160 of each connecting piece 16 overlaps the adjacent left and right wall panels 12 and 13.

Then, as shown in the fifth figure, the inner lining support plate 20 is movably overlapped on the top surface 110 of the bottom plate 11 through the first folding lines 34 located on both sides to cover the left wall plate 12, the right wall plate 13, the front wall plate 14, the rear wall plate 15 and the upper part of the plurality of connecting plates 16. Then, as described above, the adhesive sheet 24 at the edge of the right lining plate 23 is folded through the second folding line 35 and bonded and fixed to the corresponding adhesive area 25 of the right wall plate 13 to form a flat half-folded assembly state for easy storage and transportation.

Figures 6 to 11 reveal the process of assembling the invention from a half-folded state to a three-dimensional container. As shown in Figures 6 to 8, when assembling from a half-folded state, the user can apply force from the left and right sides to push the left and right wall panels 12 and 13 to bend and stand upright relative to the bottom plate 11, and respectively drive the front and rear wall panels 14 and 15 to stand upright through the corresponding connecting pieces 16, and at the same time push the inner lining support plate 20 to bend from the auxiliary indentation 31 and arch above the top surface 110 of the bottom plate 11.

As shown in Figures 9 to 11, the user can then bend the left and right linings 22, 23 along the left and right fold lines 32, 33 toward the inner side surfaces 140, 150 of the front and rear wall panels 14, 15, respectively, to drive the bottom lining 21 to move toward the bottom plate 11, and then apply force from top to bottom to press the bottom lining 21 down to overlap the top surface 110 of the bottom plate 11, while pushing the left and right linings 22, 23 toward the inner side surfaces 120, 130 of the left and right wall panels 12, 13, respectively, to quickly assemble the storage box into a three-dimensional state with a storage space. The top surface 110 of the bottom plate 11, the inner side surfaces 140, 150 of the front and rear wall plates 14, 15, and the inner side surfaces 120, 130 of the left and right wall plates 12, 13, their arrangement positions can be found in the second figure.

The assembled container box has a double-layer structure formed by the inner lining support plate 20 stacked on the top surface 110 of the bottom plate 11 and the inner side surfaces 120 and 130 of the left and right wall plates 12 and 13, thereby improving the load-bearing strength. More importantly, the inner lining support plate 20 is integrally extended from the left wall plate 12, and no additional processing molds and processes are required, which effectively saves processing costs and reduces paper waste.

It is particularly worth mentioning that during the development process of the present invention, it was found that the inner lining support plate 20 would be obstructed from folding due to the bending and squeezing of the paper material during assembly, and that an arch might be caused after the assembly is completed. In order to allow the inner lining support plate to be evenly stacked against the top surface 110 of the bottom plate 11 and the inner side surfaces 120, 130 of the left and right wall plates 12, 13 after assembly, so that the paper board can be assembled more smoothly, another feature of the present invention is that a structure that assists in folding is provided.

The specific implementation method of the auxiliary folding structure is shown in the second and ninth figures. The inner lining support plate 20 is provided with at least one notch 36 on the left and right fold lines 32 and 33 where the bottom lining 21 respectively intersects with the left and right linings 22 and 23, so that the left and right fold lines 32 and 33 form at least two connecting parts 361 on both sides of the corresponding notch 36.

When the paperboard is assembled from a half-folded state, the notch 36 and the plurality of connecting portions 361 can create a space that can be deformed and compressed at the intersection of the two sides of the bottom liner 21 and the left and right liner sheets 22, 23. On the one hand, it can reduce the obstruction of bending and squeezing of the paperboard during the assembly process, and on the other hand, it can make the bottom liner 21 overlap evenly on the top surface 110 of the bottom plate 11, and the left and right liner sheets 22, 23 overlap evenly on the inner side surfaces 120, 130 of the left and right wall panels 12, 13 respectively.

In summary, in addition to the advantages of being easy to store in a half-folded state, quickly assembled from a half-folded state, and having enhanced load-bearing strength through the inner lining support plate 20, the inner lining support plate 20 is formed by the left wall plate 12 extending outward as a whole, which can save processing costs and reduce waste of paper materials. When assembled into a three-dimensional storage box, the inner lining support plate 20 can reduce resistance through the compression space formed by the notches 36 on the left and right fold lines 32 and 33 and the connecting part 361, and can be smoothly stacked, thereby improving the refinement of the paper storage box.

The following further describes other implementation methods of this creation:

As shown in the fifth figure, in order to make the assembly process of the paperboard 100 smoother, a recessed portion 37 is respectively provided at the intersection of the upper and lower edges of the bottom liner 21 and the left and right liner 22, 23 and the left and right fold lines 32, 33. After the accommodating box is assembled, the recessed portion 37 overlaps the four corner ends of the bottom plate 11 and the front, rear, left and right wall plates 14, 15, 12, 13. In this way, the corner ends formed after the folding of the inner liner support plate 20 and the four corner ends of the front, rear, left and right wall plates 14, 15, 12, 13 can be prevented from being squeezed.

In practice, the front and rear wall panels can be provided with linings and structures to assist in positioning the linings, so that the reinforcement structure is more perfect.
