DETAILED DESCRIPTION
[0026] In order to make the utility model's purpose, technical scheme and advantage more clearly, following combining embodiment, this utility model carries out further detailed explanation. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0027] EMBODIMENT
[0028] In order to solve the technical problem in the background art, a single sheet forming glueless folding handle automatic ejection type packaging box is given as follows:
[0029] In combination Figures 1-7 As shown in the drawings, a single sheet forming a no-glue folding handle automatic ejection type packaging box is formed by folding and inserting a one-piece paperboard, which comprises a rectangular box bottom 23, first and second side plates 6 and 7 symmetrically extended and 90° folded at both ends of the box bottom 23, a pair of side plate latches 19 symmetrically extended and 90° folded at both sides of the first and second side plates 6 and 7; the third and fourth side plates 22 and 24 are symmetrically extended and 90° folded at both sides of the box bottom 23, the first and second inner side lining plates 21 and 25 are symmetrically extended and 180° folded at the side edges of the third and fourth side plates 22 and 24, and the first and second inner side lining plates 21 and 25 respectively wrap and fit two side plate latches 19 on the same side; the inner bottom lining plate 20 is extended and 90° folded reversely at the side edge of the first inner side lining plate 21, and is flatly attached to the box bottom 23, and the inner bottom lining plate 20 is inserted and locked with the second clamping slot 18 formed at the side edge of the second inner side lining plate 25 through the first clamping slot 17 formed at the side edge thereof;
[0030] The first and second side plates 6 and 7 are respectively correspondingly extended and 90° folded with the second and first box covers 3 and 2, the third and fourth latches 12 and 13 are respectively correspondingly extended and 90° folded at the side edges of the second and first box covers 3 and 2, and the third and fourth latches 12 and 13 are inserted into the through-type insertion slot formed by the first and second guide slots 8 and 9 symmetrically formed on the first and second inner side lining plates 21 and 25; the end of the inner bottom lining plate 20 towards the first side plate 6 is embedded with an inner ejection structure for automatically ejecting the product stored in the packaging box by hand.
[0031] By adopting the above technical scheme, the packaging box adopts no-glue integrated design, and the environmental protection is improved; wherein the box bottom 23 and each side plate (6, 7, 22, 24) form a three-dimensional box body through the symmetrically extended 90° folding structure, and the wrapping and fitting of the four side plate latches 19 and the inner side lining plates (21, 25) replace the traditional glue fixing; the single sheet folding and inserting design completely abandons the adhesive, reduces chemical pollution, and the material is easy to recycle, which meets the environmental protection trend. The first clamping slot 17 of the inner bottom lining plate 20 and the second clamping slot 18 of the second inner side lining plate 25 are locked by folding and inserting. The clamping slot interlocking structure is adopted instead of glue, which avoids the pollution of glue to paper material, and at the same time enhances the structural stability.
[0032] The packaging box adopts multi-stage self-locking and lining plate reinforcement, and the structural stability is enhanced. The first inner lining plate 21 and the second inner lining plate 25 completely wrap and fit the four side plate bolts 19, forming double-layer reinforcement. The dispersed external force impact prevents the deformation of the side plate during transportation, and improves the compression resistance. The third bolt 12 and the fourth bolt 13 are inserted into the through-type slot formed by the first guide slot 8 and the second guide slot 9, forming a closed locking. The precise fit of the bolt (12, 13) and the guide slot (8, 9) ensures that the box cover is tightly closed, preventing accidental opening, and simplifying the assembly process.
[0033] The packaging box is integrally formed, and the production and assembly efficiency is optimized. All side plates, bolts, lining plates and box covers (2, 3) are cut from a single sheet of paper, V-shaped, without the need for multi-component assembly. The use of single sheet cutting and folding can reduce cutting waste, reduce material costs, and the folding process can be molded by automatic equipment at one time, improving production efficiency. The wrapping and fitting of the side plate bolt (19) and the inner lining plate (21, 25), and the interlocking of the clamping groove (17, 18) are all completed by folding, without the need for additional fixing steps. The use of a plug-in buckle self-locking design simplifies the assembly process, reduces labor costs, and is suitable for mass production.
[0034] The packaging box adopts automatic ejection and easy opening design, and the user convenience is improved. The inner ejection structure embedded at the end of the inner bottom lining plate 20 is triggered by pulling the handle, and the internal product is automatically lifted. Users do not need to damage the packaging or complex disassembly, and can quickly access the product with one hand, especially for precision electronic products or fragile products.
[0035] The packaging box solves the pain points of traditional packaging relying on adhesives, complex assembly and cumbersome opening through four core structures of single sheet folding, clamping groove interlocking, guide slot bolt cooperation and inner ejection, and achieves a balance between environmental protection, production efficiency, structural strength and user experience, with significant market competitiveness.
[0036] As shown in Figure 1 , Figures 4-7 , the inner ejection structure includes a tear line 15 embedded in the corresponding middle position of the inner bottom lining plate 20. The outer end of the tear line 15 extends a handle 14 towards the first side plate 6, and the free end of the handle 14 is bent in the opposite direction around the product in the packaging box, and approaches the second side plate 7.
[0037] By adopting the technical scheme, the inner ejection structure can quickly take out the product in the packaging box in one step; when the user opens the first box cover 2, the handle 14 is exposed, and then when the user pulls the handle upward for the first time, the second box cover 3 is opened; when the handle 14 is pulled upward for the second time, the easy-to-tear line 15 is torn due to the product being pressed on the inner bottom lining plate 20, and by the principle of leverage, one end of the product is pressed on the end of the inner bottom lining plate 20 facing the second side plate 7, and the other end is lifted upward with the handle 14 and the easy-to-tear line 15, so that the product is automatically ejected to the opening of the packaging box, and the user can easily take it. When the user uses it for the first time, the user only needs to tear the easy-to-tear line 15 to release the handle 14, and then the subsequent ejection action can be triggered, thereby simplifying the opening steps and avoiding the problem of destructive disassembly of the traditional packaging.
[0038] As shown in Figure 4 and Figure 5 , the end edge of the inner bottom lining plate 20 extends and is 90° folded with the buffer lining plate 16 towards the second side plate 7, and the buffer lining plate 16 is attached to the second side plate 7.
[0039] By adopting the technical scheme, the buffer lining plate 16 can enhance the dynamic protection during the ejection process; the buffer lining plate 16 is formed by 90° folding the end edge of the inner bottom lining plate 20 and is attached and fixed to the second side plate 7 to form a rigid fulcrum of the ejection action; when the handle 14 pulls the easy-to-tear line 15 to lift the built-in product, one end of the product is pressed on the buffer lining plate 16 to form a lever action.
[0040] The buffer lining plate 16 can play a role in transportation and drop impact protection; the buffer lining plate 16 is located between the inner bottom lining plate 20 and the second side plate 7 to form a sandwich structure perpendicular to the box bottom 23. If the packaging box is impacted (such as squeezed or dropped) on the side during transportation, the buffer lining plate 16 absorbs the impact energy by its own bending elasticity to reduce the vibration transmitted to the product, and avoids the direct collision between the product and the second side plate 7. The buffer lining plate 16 serves as a lateral impact buffer layer of the second side plate 7, and the handle 14 is reversely bent around the product in the packaging box, serving as a lateral impact buffer layer of the first side plate 6.
[0041] After the buffer lining plate 16 is attached to the second side plate 7, the two together form a double-layer paperboard protection area. The bending strength of the second side plate 7 is improved to prevent the side plate from being damaged by inward indentation when stacked under pressure.
[0042] As shown in Figures 1-5 , the second box cover 3 is longer than the first box cover 2, the first and second latches 10 and 11 are symmetrically extended and 90° folded outward from the middle of the two side edges of the second box cover 3, and the first and second latches 10 and 11 are respectively inserted into the first and second lock grooves 4 and 5 formed on the second and first inner side lining plates 25 and 21.
[0043] By adopting the technical scheme, the first and second latches 10 and 11 are formed by folding the two side edges 90 degrees of the second box cover 3, and are inserted into the first and second locking grooves 4 and 5 of the first and second inner side lining plates 21 and 25; after being vertically inserted into the locking grooves, the latches form bidirectional limiting in the horizontal and vertical directions, which better prevents the box cover from being accidentally opened due to vibration or extrusion during transportation, and is particularly suitable for scenarios that are easily impacted by external forces (such as express transportation).
[0044] As shown in Figure 2 and Figure 3 The third and fourth latches 12 and 13 are pasted on the formed locking seam 1.
[0045] By adopting the technical scheme, when the user tears the easy-to-tear sealing sticker, the first box cover 2 is opened along with the easy-to-tear sealing sticker, which facilitates the opening of the first box cover 2. In addition, the locking seam 1 formed by pasting the third and fourth latches 12 and 13 is located on the closure center line of the box cover, and the easy-to-tear sealing sticker spans the gap; once the easy-to-tear sealing sticker is torn, it cannot be restored, forming a “one-time opening” mark, which effectively prevents the product from being maliciously exchanged or unpacked during transportation or sales.
[0046] Preferably, the paperboard material of the packaging box is double-sided copper plate paper with an outer film.
[0047] By adopting the technical scheme, the paperboard material is double-sided copper plate paper with an outer film, which can enhance the moisture-proof and wear-resistant performance of the paper box.
[0048] The working principle and use process of the utility model are as follows:
