Description

Technical Field

[0001] The invention belongs to the field of carton packaging, in particular to a single-piece automatically-elevated display box piece and a single-piece automatically-elevated display box folded from the single-piece piece. Background Art

[0002] Paper boxes are common packaging items, and their main advantages are low material cost, simple manufacturing, and easy mass production. At the same time, due to material limitations, it is difficult to design a linkage structure for paper boxes. Generally, they can only achieve a simple packaging effect by cutting pieces into simple connections between faces. On January 18, 2017, Chinese patent document CN205891505U, "A corrugated cardboard box using a semi-tangent tearing structure," disclosed in its first embodiment a conventional hexahedral carton and its cutting piece structure: the carton is a rectangular parallelepiped, including four side walls and a top plate and a bottom plate. This carton is known as a 04 carton in the industry and is a representative of conventional hexahedral cartons. Since the aforementioned disadvantages have not been resolved, paper box packaging has long been at the low end of the packaging market and has been unable to effectively break through, and manufacturers and consumers have also formed a deep-rooted low-end impression of paper box packaging. Chinese patent document CN105947346A, published on September 21, 2016, discloses a "side-pull multi-directional high-lift packaging" that "includes an outer box, an inner tray located in the outer box, and two inner boxes. The outer box has an open lower end, and the inner tray and the inner box are both box bodies with open upper ends. The outer box is a split symmetrical structure consisting of a left part and a right part with the same structure. The two opposite bottom edges of the inner tray are hinged to the middle of the bottom edges of the left and right parts respectively, and the inner surfaces of the left and right parts are provided with The outer surface of the inner support is symmetrically provided with two sets of arc-shaped slides matching the wings, and the wings are located in the arc-shaped slides; a partition is provided in the inner support, and the inner support is divided into two inner cavities by the partition, and the two inner boxes are respectively located in the two inner cavities and the bottoms of the inner boxes are provided with push pieces; push plates are fixed on the inner surfaces of the left and right parts, and the push plates are L-shaped, with the vertical part of the push plates fixedly connected to the outer box, and the horizontal part is located in the inner cavity of the inner support and in contact with the push pieces, and the push plates and push pieces are both magnets. The applicant claims that the above technology "has a novel structure, is easy to open and can accommodate a variety of items." Analysis of this existing technology shows that although it achieves the linkage effect between components, it uses a large number of independent parts, the assembly cost is very high, and the use of materials other than paper makes it inconvenient to recycle. Overall, this solution fails to use all-paper materials to manufacture a paper box with a linkage structure in a convenient way, and the inherent advantages of paper boxes such as environmental protection, lightness and easy recycling are not effectively utilized. Summary of the Invention

[0003] Based on the above problems, the present invention provides a single-piece automatic lifting display box piece, which is made of a single piece and does not require the addition of other parts. The lifting of the inner box is achieved through a linkage mechanism. On this basis, the present invention also provides a single-piece automatic lifting display box made by folding the piece, which achieves the effect of automatically lifting the items in the box when the paper box is opened through a linkage mechanism.

[0004] In order to achieve the first object of the invention, the present invention adopts the following technical solution: a single-piece automatically raises the display box piece, including a front outer panel, a top panel, a rear side panel, a bottom panel and a front inner panel connected in sequence from bottom to top, the upper side of the front inner panel is connected to a movable panel, and the shape and size of the movable panel are adapted to the size of the bottom panel; the upper side of the movable panel is connected to the movable panel rear connecting panel; the upper side of the movable panel rear connecting panel is connected to the fixed panel rear connecting panel; the upper side of the fixed panel rear connecting panel is connected to the top panel fixed panel; the height of the movable panel rear connecting panel and the fixed panel rear connecting panel after folding is adapted to the height of the rear side panel after folding.

[0005] The single-piece, self-elevating display box panel designed in this technical solution is typically used in carton structures with parallel front and rear sidewalls, such as rectangular, trapezoidal, or hexagonal cross-sections with parallel top and bottom edges. Rectangular shapes are the most common. The existing technology for the 04 carton body comprises a front outer panel, top panel, rear side panel, bottom panel, and front inner panel, connected from bottom to top. The front outer panel and top panel, when folded, form the lid, while the bottom panel and front inner panel, when folded, form the box body. The lid and body are connected via the rear side panel, creating a flip-and-lock relationship between the lid and the box body. The sidewall structure of the lid and the box body is well known to those skilled in the art and can be selected by those skilled in the art as needed. Furthermore, a movable panel is connected to the upper side of the front inner panel, with the shape and dimensions adapted to those of the bottom panel. This movable panel, located within the box body after folding, serves as the follower component in this solution. The movable piece has a connection relationship as follows: the upper side of the movable piece is connected to the movable piece rear connecting piece, and the upper side of the movable piece rear connecting piece is connected to the fixed piece rear connecting piece. The upper side of the fixed piece rear connecting piece is connected to the top plate fixing piece. When folded into a box, the top plate fixing piece will be fixed to the top plate in the box lid and will flip as the box lid is opened and closed. The flip axis is the straight line where the connection edge of the top plate and the rear side plate is located. After folding into the box, the folded fixed piece rear connecting piece is located in front of the rear side plate, and the movable piece rear connecting piece is located in front of the fixed piece rear connecting piece. When the box lid and the box body are in a buckled state, the top plate is above the top plate fixing piece, and the top plate fixing piece is above the movable piece. Due to the aforementioned positional relationship, the folded paper box forms a triangle in its side cross-sectional view: the connection point between the rear side plate and the top plate is one point, the connection point between the top plate fixing piece and the movable piece rear connecting piece is another point, and the intersection point where the movable piece rear connecting piece extends upward to intersect with the top plate is the third point. Assuming the thickness of the top plate's fixed plate remains constant, the triangle will not deform. Furthermore, as the lid opens, the top plate flips, and the top plate's fixed plate rotates, the triangle will also rotate around the edge connecting the rear side panel and the top plate. This rotation causes the fixed plate's rear connecting plate to move upward and backward. After folding into the box, the lower end of the fixed plate's rear connecting plate connects to the lower end of the movable plate's rear connecting plate, which in turn connects to the movable plate's rear connecting plate. Therefore, the upward movement of the fixed plate's rear connecting plate indirectly causes the movable plate to lift upward at its rear end. The rearward movement of the fixed plate's rear connecting plate is limited by the rear side panel. If the fixed plate's rear connecting plate cannot retract, the movable plate's rear connecting plate cannot simply adjust its angle with the fixed plate's rear connecting plate. This also forces the upper end of the movable plate's rear connecting plate to rise, driving the rear end of the movable plate upward. Thus, as the lid rotates upward and backward, the fixed plate, the fixed plate's rear connecting plate, and the movable plate's rear connecting plate ultimately drive the movable plate to rotate around its connection with the front inner panel, significantly raising its rear end. By rationally utilizing this structure, it is possible to design excellent packaging, which is beneficial to improving the grade of all-paper packaging, while also having the advantages of saving materials and facilitating recycling.Even without adding other auxiliary structures, it is already possible to place thin sheets on the movable plate, such as precious old photos. The parameters of the aforementioned triangle are the factors that determine the sensitivity and amplitude of the movable plate's lifting action. Therefore, those skilled in the art can select appropriate parameters as needed to meet design requirements.

[0006] Preferably, a support plate is provided, which is fixed relative to the movable plate; a storage hole is provided through the movable plate; and a left support plate and a right support plate are connected to the left and right sides of the movable plate, respectively. The height of the left and right support plates of the movable plate after folding is adapted to the height of the front outer panel, front inner panel, and rear side panel after folding. This solution adds a support plate, which is fixed below the movable plate after folding into the box. The movable plate is provided with a storage hole through the support plate. The peripheral limit function of the storage hole and the lower limit function of the support plate cooperate to form a retaining structure for placing the required items. The storage hole can be one or as many as required by the design. The shape of the storage hole and the depth of the support plate are determined by those skilled in the art based on actual needs. In this state, the weight of the items is primarily supported by the movable plate, so the movable plate requires an additional support structure, namely the left and right support plates provided in this solution. When folded into the box, the lower ends of the two support plates contact the bottom plate to support the weight. The pallet can also be further designed with blind holes, recesses, slots, holes and other positioning and limiting structures to position and limit items placed on the pallet.

[0007] Preferably, the left and right sides of the pallet are connected to a left connecting plate and a right connecting plate, respectively. The left connecting plate is connected to the left side of the left support plate of the movable sheet, or the right connecting plate is connected to the right side of the right support plate of the movable sheet. The heights of the left connecting plate and the right connecting plate after folding are equal, and are not greater than the heights of the left support plate and the right support plate of the movable sheet after folding. In terms of the specific connection method between the pallet and the movable sheet, this solution provides a design of a left connecting plate and a right connecting plate, one end of which is connected to the support plate on one side of the movable sheet, and the other side is fixed to the support plate on the other side of the movable sheet by gluing, nailing, etc. when folded into a box. It should be noted that in order to better realize the function of limiting the bottom of the pallet, it is generally necessary to keep the pallet parallel to the movable sheet after fixing.

[0008] Preferably, the top plate is rectangular; the two side edges of the top plate are respectively connected to the left outer plate and the right outer plate of the box lid; the left side of the left outer plate of the box lid is connected to the left inner plate of the box lid, and the left side of the right outer plate of the box lid is connected to the right inner plate of the box lid; the heights of the left inner plate and the right inner plate of the box lid after folding are respectively adapted to the heights of the left outer plate and the right outer plate of the box lid after folding; a fixing structure is provided between the left inner plate of the box lid, the right inner plate of the box lid and the bottom plate. When the box body and the box lid are limited to being rectangular, the left and right outer plates of the box body can be designed to be connected on the left and right sides of the box lid, and further structural reinforcement can be performed by the left and right inner plates of the box lid. The box body can also be designed in the same way, which will not be described in detail here.

[0009] Preferably, the fixing structure comprises positioning holes extending through the bottom plate at the junctions with the left and right outer panels. Positioning tongues protrude from the left and right edges of the left and right inner panels, and are adapted to engage with the positioning holes. The adaptable engagement of the positioning tongues with the positioning holes serves to position the left and right inner panels of the box body, preventing them from disjointing. Similarly, this design can also be applied to corresponding structures within the box body, and will not be further elaborated here.

[0010] Preferably, the left and right edges of the front outer panel are connected to a left and right front outer panel connecting piece, respectively. The widths of the left and right front outer panel connecting pieces match the widths of the left and right outer panels. This solution provides a fixing structure for the front outer panel, effectively securing the panel by sandwiching the left and right front outer panel connecting pieces between the left and right inner and outer panels of the box cover, respectively. Similarly, this solution can also be applied to the rear side panels and front inner panel, and will not be further described here.

[0011] Preferably, an anti-bending connecting piece is further connected between the rear connecting piece of the fixing piece and the top plate fixing piece. When the box cover is further flipped upward and backward, the force on the rear connecting piece of the fixing piece is concentrated and it is easy to bend. After studying this situation, this solution actively designs the rear connecting piece of the fixing piece to be shorter, and at the same time adds an anti-bending connecting piece between the rear connecting piece of the fixing piece and the fixing piece. On the one hand, it can actively guide the force to bend along the existing crease line, reducing damage to the overall cut piece. On the other hand, the connection point between the rear side panel and the top plate can be used as a fulcrum and the anti-bending connecting piece can be used as a lever to form a lever structure, which further transmits the effect of flipping the box cover to the movable piece, forming a better lifting effect of the movable piece. The length of the anti-bending connecting piece exceeds the length of the line between the connection point between the aforementioned triangular rear side panel and the top plate and the connection point between the top plate fixing piece and the rear connecting piece of the movable piece.

[0012] The foldable box body is a box body that is designed to be lifted up when the lid is opened, and the foldable box body is a box body that is designed to be lifted up when the lid is opened.

[0013] This design uses a single piece to automatically elevate the display box. The box body and lid are conventional structures, but a movable piece is connected via the upper edge of the front inner panel. After folding into a box, this movable piece is located within the box body and serves as a follower component in this design, allowing it to rise and fall as the lid opens. The main principle is as follows: the front end of the movable piece is rotationally connected to the upper edge of the inner front panel, while the rear end is rotationally connected to the upper edge of the movable piece's rear connecting piece, and the lower edge of the movable piece's rear connecting piece is rotationally connected to the lower edge of the fixed piece's rear connecting piece. The upper edge of the fixed piece's rear connecting piece is rotationally connected to the lower edge of the top plate fixing piece, which is fixed to the top plate in the lid and will flip as the lid opens and closes. The flip axis is the straight line connecting the top plate and the rear side panels. The fixed plate rear connecting piece is located on the front side of the rear side panel, and the movable plate rear connecting piece is located on the front side of the fixed plate rear connecting piece. When the lid and box body are in the buckled state, the top panel is above the top plate fixing piece, and the top plate fixing piece is above the movable piece. Due to the aforementioned positional relationship, the folded carton forms a triangle in its side cross-sectional view: the connection point between the rear side panel and the top panel is one point, the connection point between the top plate fixing piece and the movable plate rear connecting piece is another point, and the intersection point where the movable plate rear connecting piece extends upward and intersects with the top panel is the third point. Assuming the thickness of the top plate fixing piece is constant, this triangle will not deform. As the lid opens, the top panel flips over, and the top plate fixing piece rotates accordingly, the triangle will also rotate around the connecting edge of the rear side panel and the top panel as the axis. This rotation causes the fixed plate rear connecting piece to move upward and backward. The lower end of the fixed plate rear connecting piece is connected to the lower end of the movable plate rear connecting piece, and thus connected to the movable plate. Therefore, the upward movement of the fixed plate rear connecting piece indirectly causes the movable plate to lift up at the rear side. The rear side panel limits the rearward movement of the fixed plate's rear connecting piece. As the lid rotates upward and backward, the fixed plate, the fixed plate's rear connecting piece, and the movable plate's rear connecting piece ultimately drive the movable plate to rotate about its connection with the front inner panel, significantly raising its rear end. This solution, made entirely of paper and without any external components, creates a linkage mechanism within the box, producing a significant linkage effect.

[0014] Preferably, a support plate is also provided; the left and right sides of the movable plate are connected to the vertical movable plate left support plate and the movable plate right support plate, and the height of the movable plate left support plate and the movable plate right support plate is adapted to the height of the front outer plate, the front inner plate and the rear side plate; the support plate is located below the movable plate and is fixedly connected to the movable plate left support plate and the movable plate right support plate; a material hole is provided through the movable plate, and the position of the material hole corresponds to the position of the support plate below.

[0015] Preferably, the present solution provides a pallet as a limiting structure below the carton, and a hole is designed on the movable sheet as a limiting structure on the side. The two cooperate to form a limiting structure on which the required items can be placed. There can be one hole or the number required by the design. Specifically, the shape of the hole and the depth of the pallet setting are all determined by those skilled in the art according to actual needs. In this state, the weight of the items is mainly supported by the movable sheet, so the movable sheet needs to be equipped with an additional support structure, namely the left support sheet and the right support sheet provided in this solution. The lower ends of the two sheets contact the bottom plate after being folded into a box to support the weight. Blind holes, recesses, slots, openings and other positioning and limiting structures can be further designed on the pallet to position and limit the items placed on the pallet.

[0016] Preferably, an anti-bending connecting piece is connected between the rear connecting piece of the fixing piece and the top plate fixing piece. The anti-bending connecting piece is designed to, on the one hand, actively guide the force to bend along the existing crease line, reducing damage to the entire cut piece, and on the other hand, the connection point between the rear side panel and the top plate can be used as a fulcrum and the anti-bending connecting piece as a lever to form a lever structure, further transmitting the effect of the box cover flipping to the movable piece, forming a better lifting effect for the movable piece. The length of the anti-bending connecting piece exceeds the length of the line connecting the connection point between the aforementioned triangular rear side panel and the top plate and the connection point between the top plate fixing piece and the rear connecting piece of the movable piece.

[0017] In summary, the beneficial effects of the present invention are as follows: the single-piece automatic lifting display box piece is made of a single piece, without the need to add other parts, and the lifting of the inner box is achieved through a linkage mechanism; the single-piece automatic lifting display box can achieve the effect of automatically lifting the items in the box when the paper box is opened through a linkage mechanism.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1 The embodiment 1 shown is a single-piece automatically raised display box piece, which is connected in sequence from bottom to top in a vertical column with a front outer panel A, a top panel B, a rear side panel C, a bottom panel D, a front inner panel E, a movable panel F, a movable panel rear connecting panel G, a fixed panel rear connecting panel H, an anti-bending connecting panel J and a top panel fixed panel K. The cross-section of the paper box formed by folding the pieces in this example is square, so the top panel, bottom panel and movable panel are all square.

[0026] The left and right sides of the front outer panel are connected to a front outer panel left connecting piece A1 and a front outer panel left connecting piece A2 respectively.

[0027] The left and right sides of the top plate are connected to the left outer plate B1 and the right outer plate B2 of the box cover respectively. The left side of the left outer plate of the box cover is connected to the left inner plate B3 of the box cover, and the right side of the right outer plate of the box cover is connected to the right inner plate B4 of the box cover.

[0028] The left and right sides of the rear side panel are respectively connected with a rear side panel left connecting piece C1 and a rear side panel left connecting piece C2.

[0029] The left and right sides of the bottom plate are connected to the left outer plate D1 and the right outer plate D2 of the box body respectively. The left side of the left outer plate of the box body is connected to the left inner plate D3 of the box body, and the right side of the right outer plate of the box body is connected to the right inner plate D4 of the box body.

[0030] The left and right sides of the front inner panel are connected to a front inner panel left connecting piece E1 and a front inner panel left connecting piece E2 respectively.

[0031] The movable plate is connected to the left and right sides of the movable plate with a left support plate F1 and a right support plate F2, respectively. The left side of the movable plate's left support plate is also connected to a support plate L. The width of the support plate matches the width of the movable plate. The left and right sides of the support plate are connected to a left support plate connecting plate L1 and a right support plate connecting plate L2, respectively. The right side of the right support plate connects to the left side of the movable plate's left support plate.

[0032] A positioning hole 1 is provided at the connection part between the top plate and the left outer plate and the right outer plate of the box cover, and a positioning tongue 2 is provided at the corresponding position protruding on the left side of the left inner plate and the right side of the right inner plate of the box cover. The positioning hole and the positioning tongue form an adaptive plug-in relationship.

[0033] Similarly, the above-mentioned positioning and plugging relationship is also set on the horizontal row where the bottom plate is located.

[0034] The movable piece is provided with an object hole 3. The object hole of this example is a square hole arranged in the center.

[0035] Taking the left side of the cut piece as an example, the left connecting piece of the front outer panel, the left outer panel of the box lid, the left inner panel of the box lid, the left connecting piece of the rear panel, the left outer panel of the box body, the left inner panel of the box body, and the left connecting piece of the front inner panel are all located on the side of the carton after folding, forming the side wall of the carton. Therefore, their widths meet the mutual adaptation relationship well known to those skilled in the art. The same applies to the right side of the cut piece.

[0036] The left and right support plates of the movable plate need to support the weight of the movable plate and the items on the pallet, so their width should be sufficient to directly touch the bottom plate at their outer ends. Correspondingly, the width of the left and right connecting plates of the pallet is smaller than that of the left and right support plates of the movable plate.

[0037] To reduce space, icons will be used instead of corresponding Chinese names in the following description of the steps and principles of folding the pieces into a box and opening it for use.

[0038] Step 1, such as Figure 2 , bend A1 and A2, B1 and B3, B2 and B4 inward, and insert and position them through the positioning holes and positioning tongues to complete the folding of the box cover;

[0039] Step 2, such as Figure 3 , bend D1 and D3, D2 and D4, E1 and E2 inward, and similarly insert and position them through the positioning holes and positioning tongues to complete the folding of the box body;

[0040] Step three, such as Figure 4 , bend L2 inward along the crease line until it is close to F1 and glue it;

[0041] Step 4: Figure 5, bend F1 and F2 upward and inward to a vertical shape, then stick L2 close to F2 and glue them together. Be careful to keep L and F parallel, and the position of L corresponds to the position of the hole on F;

[0042] Step five, such as Figure 6 , bend G upward and inward to a vertical shape, then use H to drive J and K to bend downward and outward to a vertical shape;

[0043] Step six, such as Figure 7 , using the connecting edge of E and F as the axis, rotate F inward so that F1, F2, G, H, and J enter the box together, and F is located at the top of the box; at this time, adjust the relative position of K and B according to the set size, and finally glue K and B;

[0044] Step seven, such as Figure 8 , close the box cover forward and downward, and the paper box is folded.

[0045] Example 2

[0046] like Figure 8 The second embodiment shown is a single-piece automatic lifting display box, which is made by folding the pieces in the first embodiment.

[0047] like Figure 9 As shown, when the lid of the single-piece automatic lifting display box is flipped upward and backward, as B flips outward and downward, F will rotate around the connecting edge of E and F, forming a state where the rear side is raised, and driving L to rise synchronously.

[0048] The working principle of this design is shown in Figure 10 、 Figure 11 、 Figure 12 .

[0049] Figure 10 The figure shows the lid snapped onto the box body. G is vertically positioned in front of HJ, which is in front of C, and F is horizontal. The shaded triangle in the figure is a right triangle, with its three vertices being the intersection of C and B, the intersection of J and K, and the intersection of J's upward extension and B. Because K's thickness is fixed and the positions of K and B are bonded together, the triangle maintains its shape and dimensions throughout the box's use.

[0050] Figure 11 The box lid is flipped upward to a vertical position. The shaded triangle rotates accordingly, and JH moves upward while moving backward. The effect is this: when H retreats to a position just in front of C, H cannot move further backward and can only drive G upward. This increases the angles between H and G, and between G and F. Meanwhile, both the lower and upper endpoints of G move upward, driving F to rotate about the intersection of H and E, causing the rear side of F to rise.

[0051] Figure 12 The figure shows the lid flipped further back to a horizontal position. The shaded triangle continues to rotate, with J extending along the triangle's slope. The connection point between J and H forms the axis of rotation, while H remains vertical. The resulting angles between H and G, and between G and F, decrease. However, H's further upward movement also produces a small amount of forward movement, pushing F to rotate further upward, causing the rear side of F to rise further.

[0052] When closing the box cover, the movements of the various components are opposite. JH returns to its vertical position and moves downward, driving G downward. The downward movement of G drives F to rotate backward and downward, causing the rear side of F to drop and return to its initial position.
