Description

Technical Field

[0001] The present invention relates to the technical field of packaging consumables in the packaging industry, and particularly to a foldable integrated paper tray capable of rapid prototyping and its cardboard structure. Background Art

[0002] Paper trays or carton linings are indispensable protective consumables in packaging boxes and are key components during the transportation and storage of packed goods. They can effectively protect the goods inside the box, play the roles of supporting and protecting the goods, and can also maintain the specific placement posture of the goods in the box and support the goods to ensure their stable, reliable, and safe storage or transportation. Paper trays and carton linings provide excellent buffering and shockproof effects. Whether facing external impacts or squeezes, they can play a reliable protective role and maintain the integrity of the internal goods. At the same time, paper trays and carton linings have excellent fixing functions. When goods are placed on the paper tray, providing additional structural support, they will firmly fix the goods and avoid unnecessary movement or collision during transportation. Whether bearing heavy weights or stacked packaging, they can maintain the stability and stiffness of the box body and reduce the risk of deformation and damage.

[0003] Among the existing carton linings, plastic trays, foam trays, and paper trays are the most common options. However, these linings usually require the combination and adaptation of multiple components to be used. For example, in some cases, two paper frames need to be combined together, or a paper frame is used in combination with a plastic tray to achieve better effects. Also, due to the large number of components, on the one hand, for the storage and transportation of consumables, this combined installation method consumes a large amount of manpower and time during the process, resulting in low efficiency. On the other hand, when dealing with special shapes or different goods, it is usually difficult for paper trays to achieve a perfectly adapted shape and need to be used in combination with other shaped linings, which also increases the cost of consumables. Currently, there is a lack of a cardboard lining with a wide application range, convenient operation, and high efficiency in the market. Summary of the Invention

[0004] In order to solve the above-mentioned deficiencies and defects existing in the prior art, through research and design by the inventor, there is now provided a foldable integrated paper tray capable of rapid prototyping and its cardboard structure. Aiming at the defects in the prior art, this design can greatly improve the integrity and operation convenience of the carton lining, has a wide application range, can conveniently make groove structure processing adapted to the shape characteristics of the goods, and can be directly folded into shape during use, which is efficient, convenient, easy to use, and practical.

[0005] Working principle of the present invention: The paper tray structure of the solution provided by the present invention can be made ready for use after a cardboard is pre-cut and pre-pasted. After the pretreatment is completed, the entire cardboard structure is in a sheet form, which is convenient for storage, stacking, transportation and storage; it is also very convenient to use. Only by squeezing and pushing the cardboard from both ends can it be immediately formed and can be directly placed in a cardboard box for use. During pre-operation, first apply glue to the first bonding parts at both ends manually or automatically, and then fold the ends along the second crease so that the first bonding parts at both ends are bonded and fixed on the central waist line of the cardboard; at this time, the entire surface between the second crease and the first bonding crease is folded in place along the second crease. When in use, the two ends of the cardboard are squeezed. Because the first bonding parts are bonded and fixed, when the cardboard is folded upward along the first crease, the inner lining frame generates a folding movement along the first bonding crease, the second crease, the first inner lining crease, the second inner lining crease, the third inner lining crease, and the shoulder crease. Due to the existence of the pre-cut seams, the third inner lining crease is folded inward, thus forming a semi-groove structure, and the bottom surface of the groove is the inner lining tabletop; the inner lining tabletops at both ends approach each other, so the two semi-groove structures form a storage groove. When the inner lining body is placed in a cardboard box, the storage groove can be used to place the items to be contained. When necessary, an n-shaped cut seam can be provided in the inner lining frame. One end of the stabilizing piece generated by the n-shaped cut seam is the second bonding part, which is bonded and fixed during pretreatment, so as to drive the third inner lining crease to fold inward and thus quickly form when the paper tray is unfolded, and the stabilizing piece can provide the support firmness of the inner lining tabletop.

[0006] Advantageous technical effects of the present invention compared with existing products:

[0007] (1) For the paper tray structure of the present invention, the cardboard structure is integrally formed, the processing is convenient, and it is fast and efficient to use. It can be unfolded and formed quickly and conveniently, improving the operation efficiency during boxing. There is no need for redundant accessory and component assembly links, greatly improving the use and installation efficiency of the paper tray; the integrated folding paper tray of the present invention has a small volume after being produced and is a folded sheet structure. During the logistics transportation process, it has a smaller volume than some foams, pearl cottons, and plastics, lower logistics costs, and is more economical.

[0008] (2) The paper tray structure design of the present invention has a clever shape. There is a certain height between the inner lining tabletop and the bottom, forming the effect of a supporting platform. Moreover, the height of the tabletop and the buffer height at the bottom can be arbitrarily adjusted according to the positions of the pre-cut seams and the first inner lining creases, and a suitable preset support height can be made according to the needs of the product. The vertical depth of the product placed in the storage slot can be adjusted according to the product needs. Only by controlling the design positions of the second inner lining crease, the third inner lining crease, and the first inner lining crease, the required storage depth can be controlled. Similarly, the lateral buffer thickness of the product placed in the storage slot can also be arbitrarily adjusted. By controlling the relative positions of the second inner lining crease and the third inner lining crease, the adjustment can be made. The wall frames that can buffer the product on all four sides can be adjusted in size arbitrarily according to the needs, and have excellent applicability.

[0009] (3) The paper tray structure design of the present invention can meet the use of various shaped products. In addition to common cubic boxed products, by processing the storage cut seams to adapt to the product shape, it can also meet the placement of other shaped products, such as cup-shaped and bottle-shaped products. The gaps can be set between the storage cut seams to avoid mutual contact, so that glass bottle products can be loaded. Or through the special shape of the storage cut seams, products such as wine bottles, wine glasses, and even other products, such as electronic products and special-shaped handicrafts, can be placed. It realizes that the overall external structure remains unchanged, while various grooves can be changed inside according to different shapes and different products to play the function of fixing the product, and can meet the requirements of stable loading, buffering and anti-collision, and stable placement, with wide applicability.

[0010] (4) The cardboard material can be selected as recyclable paper, which is more environmentally friendly than traditional foam trays, plastic linings, pearl cotton materials, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0028] Embodiment 1: A foldable integrated paper tray cardboard structure capable of rapid prototyping, which is composed of a single corrugated cardboard, as Figure 1 shown:

[0029] The first bonding part 1 is located at both ends of the cardboard, and is used to be bonded to the central part of the cardboard after folding along the first bonding crease 2;

[0030] The first crease 3 is two pre-crease lines arranged along the width direction of the cardboard, and are both set in the central part of the cardboard. The paper surface between the two first creases 3 forms the bottom surface of the paper tray;

[0031] The second crease 4 is two pre-crease lines arranged along the width direction of the cardboard. The interval between the second crease 4 and the adjacent first crease 3 forms the side wall of the paper tray, and the distance is the overall height of the paper tray; The area from the second crease 4 to the end of the cardboard adjacent to it forms a folding inner lining surface;

[0032] Symmetrically arranged inner lining frames 5 are provided on both folding inner lining surfaces. The inner lining frame 5 includes two vertical pre-cut slits 6, a first inner lining crease 7 and a second inner lining crease 8 connecting the endpoints of the two pre-cut slits 6, and a third inner lining crease 9 horizontally placed between the two pre-cut slits 6; A shoulder mark 10 is provided between the pre-cut slit 6 and the edge of the cardboard;

[0033] After the cardboard is pushed from both ends, it can form an inner lining side frame along the first bonding crease 2, the first crease 3, and the second crease 4. A groove concave inward relative to the paper tray is formed between the first inner lining crease 7 and the third inner lining crease 9. The groove forms the inner lining table surface 11, and the two inner lining table surfaces 11 together form a raised object placement table surface.

[0034] Spare preparation, as Figure 2 shown. First, apply glue to the first bonding parts 1 at both ends manually or automatically, and then fold the ends along the second crease 4 so that the first bonding parts 1 at both ends are bonded and fixed on the central waist line of the cardboard; At this time, the entire surface between the second crease 4 and the first bonding crease 2 is folded in place along the second crease 4.

[0035] During use, as Figure 3 shown, hold both ends of the cardboard and squeeze inward. The two ends of the cardboard are squeezed. Due to the first bonding part 1 being paste-fixed, when the cardboard is folded upward along the first crease 3, the inner lining frame 5 generates a folding movement along the first bonding crease 2, the second crease 4, the first inner lining crease 7, the second inner lining crease 8, the third inner lining crease 9, and the shoulder mark 10. Due to the existence of the pre-cut slit 6, the third inner lining crease 9 is folded inward, thus forming a semi-groove structure, and the bottom surface of the groove body is the inner lining table surface 11; The inner lining table surfaces 11 at both ends approach each other, so the two semi-groove structures form an object placement groove 20. Place the inner lining body 18 in the cardboard box, and the object placement groove 20 can be used to place the items to be contained.

[0036] Preferably, as Figure 1 shown, a plurality of N-shaped slits 15 are arranged side by side in the middle of the inner lining frame 5 in the transverse direction. A second bonding crease 16 is provided on the stabilizing piece 12 formed by the N-shaped slits 15. One end of the bonding indentation to the end is the second bonding portion 17, and the second bonding portion 17 is bonded to the corresponding cardboard surface below after folding. One end of the stabilizing piece 12 generated by the N-shaped slit 15 is the second bonding portion 17, which is bonded and fixed during pretreatment, facilitating the inward folding of the third inner lining crease 9 when the paper tray is unfolded, thus quickly forming, and the stabilizing piece 12 can provide the support firmness of the inner lining tabletop 11.

[0037] The first bonding portions 1 at both ends of the cardboard are tooth-shaped structures that can be spliced with each other.

[0038] Preferably, as Figure 10 shown, on the folded inner lining surface, a single or a plurality of closed-shaped storage slits 13 are opened in the transverse direction, so that the opposite storage slits 13 on both sides after folding can be combined into a storage slot 14; the shape of the storage slot 14 is adapted to the outer shape of the article placed in the paper tray, so that the article can be placed in the storage slot 14 fittingly. The storage slit 13 includes an arc side and a straight side, and the intersection of the arc side and the straight side is on the first inner lining crease 7; the radian of the arc side is consistent with the outer shape radian of the placed article; the placed article is a plurality of vertically placed bottles or horizontally placed wine bottles. As Figures 11 - 14 shown, after processing the storage slit 13 to adapt the storage slit 13 to the commodity shape, it can meet the requirement of placing commodities with other shaped outer shapes. For example, for cup-shaped and bottled commodities, gaps can be provided between the storage slits 13 to avoid mutual contact, so that glass bottle commodities can be loaded; or through the special shape of the storage slit 13, commodities such as wine bottles, wine glasses, and even other commodities such as electronic products and special-shaped handicrafts can be placed. It realizes that the overall external structure remains unchanged, while the interior can be changed into various grooves according to different shapes and different products to play the function of fixing the products, and can meet the requirements of stable loading, buffering and anti-collision, and stable placement, with wide applicability.

[0039] Embodiment 2: A foldable integrated paper tray capable of rapid forming, used as an inner lining for containing articles in a packaging box 19 or a packaging box, as Figure 4 shown, it includes:

[0040] An inner lining body 18, the outer shape of which is adapted to the inner cavity structure of the packaging box 19 or the packaging box, and can be placed into the packaging box 19 or the packaging box. A storage groove 20 is opened downward from the upper direction on the front surface of the inner lining body 18;

[0041] The storage slot 20 is used to place a single item or several items to be accommodated. The width and quantity of the storage slot 20 are adapted to the shape, size and quantity of the items to be placed. There is a cavity gap between the side and bottom of the storage slot 20 and the side wall and bottom of the inner lining body 18.

[0042] The inner lining body 18 is composed of two symmetrically opposed inner lining halves. Each inner lining plate is provided with a semi-groove structure, and the two semi-groove structures are opposed to each other to form the storage slot 20.

[0043] The semi-groove structure includes an inner lining tabletop 11 for placing objects. After the two symmetrically opposed inner lining halves are joined together by molding, the two inner lining tabletops 11 are flush and at the same height to form a storage tabletop.

[0044] Further, a plurality of stabilizing pieces 12 extend from the side of the storage slot 20 along the plane where the inner lining tabletop 11 is located towards the side wall of the inner lining body 18. The end face of the stabilizing piece 12 is bonded to the side wall of the inner lining body 18 to provide support and stability for the storage tabletop.

[0045] Further, the foldable integrated paper tray is formed by folding and pasting a cardboard and then squeezing and folding it from both ends.

[0046] As Figures 7 - 9 shown, the paper tray structure design has a clever shape feature. The inner lining tabletop 11 has a certain height from the bottom, forming the effect of a support platform. Moreover, the tabletop height and the bottom buffer height can be arbitrarily adjusted according to the positions of the pre-cut seams 6 and the first inner lining creases 7, and a suitable support height preset can be made according to the needs of the product. The vertical depth of the commodity placed in the storage slot 20 can be adjusted according to the product needs. Only by controlling the design positions of the second inner lining crease 8, the third inner lining crease 9 and the first inner lining crease 7, the required storage depth can be controlled. Similarly, the lateral buffer thickness of the commodity placed in the storage slot 20 can also be arbitrarily adjusted. By controlling the relative positions of the second inner lining crease 8 and the third inner lining crease 9, the adjustment can be made. The wall frames that can buffer the commodity on all four sides can be arbitrarily adjusted in size according to the needs, and have excellent applicability.

[0047] Embodiment 3: As Figure 15As shown, the shape formed by the storage slit 13 is adapted to the outer shape of the item to be placed, and the opening position is restricted to the side wall between the second crease 4 and the adjacent first crease 3. In the use state, the placed item is completely embedded in the shape groove formed by the storage slit 13, wrapping the item as a whole. With such a design and usage method, for some items with irregular or special-shaped bottles, digital accessories, etc., the side wall space under the inner lining can be utilized, and the side wall can be used as the grooving part to fix and accommodate the product, while the upper inner lining tabletop constitutes a top surface to play a protective role, forming a complete wrapping structure to achieve a more reliable and complete wrapping and accommodation.

[0048] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
