They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] like Figures 1 to 5As shown, a paper tray container for packaging hardware parts includes a first mold shell 1 and a second mold shell 2, both of which are dry-pressed paper tray structures; the first mold shell 1 is concave inside to form a plurality of first accommodating cavities 4 and a plurality of second accommodating cavities 5, the first accommodating cavities 4 are square, and the second accommodating cavities 5 are circular, and the second mold shell 2 extends a plurality of socket plates 8 and a plurality of column slot covers 7 toward the first mold shell 1, the socket plates 8 are matched one-to-one with the first accommodating cavities 4, and the column slot covers 7 are matched one-to-one with the second accommodating cavities 5; the first accommodating cavity 4 is composed of two symmetrically arranged concave groove plates 41, all the concave groove plates are arranged in two rows along the length direction of the long side wall, and a long strip of middle groove body space is formed between the two rows of concave groove plates.

[0031] Each concave groove plate member 41 comprises two opposing groove walls and a connecting wall connecting the side edges of the two groove walls. The opposing groove walls protrude to form clamping plates 9. The clamping plates 9 on the two groove walls are symmetrically arranged, and the spacing between the clamping plates 9 decreases from top to bottom. The space between the two symmetrical clamping plates 9 forms a narrowing hopper structure from top to bottom, which is further utilized to facilitate the clamping of the end faces of parts with different calibers.

[0032] Preferably, the lower end of the splint 9 is a free end and has a certain distance from the bottom of the groove. An elastic portion 10 is provided at the position of the free end of the splint 9 on the groove wall. The elastic portion 10 abuts against the free end of the splint 9 close to the groove wall. In this way, the product is clamped by the splint 9 to prevent the product from shaking and being damaged. Preferably, the elastic portion 10 is a soft plate with one end rolled inward, and the rolled end of the elastic portion 10 abuts against the free end of the corresponding splint 9 close to the groove wall. The elastic portion 10 serves as a supporting structure between the splint 9 and the groove wall. The elastic supporting surface can facilitate the clamping activity of the splint 9 to adapt to the clamping of parts of different specifications and types. In other embodiments, the elastic portion 10 can also adopt other structures, such as folding into a spring shape.

[0033] The middle portion of the inner bottom surface of the second accommodating cavity 5 protrudes to form a tenon post 6, and the top surface of the tenon post 6 is provided with a cross-cut. The cover end of the post slot cover 7 is provided with an inwardly recessed notch, and a cross post is provided in the middle of the notch for engaging with the cross-cut of the tenon post 6. When the first mold 1 and the second mold 2 are closed, the cross post is inserted into the cross-cut of the tenon post 6, ensuring that the post slot cover 7 firmly covers the second accommodating cavity 5 and prevents it from easily falling off, thereby ensuring the sealing strength of the second accommodating cavity 5 and the post slot cover 77.

[0034] In this embodiment, the first mold shell 1 includes a square bottom plate and four side walls vertically connected to the bottom plate, the four side walls include two long side walls 12 and two short side walls 13, the two long side walls 12 are opposite, the two short side walls 13 are opposite, the middle parts of the two short side walls 13 are connected by a partition plate 14, and the partition plate 14 is parallel to the long side wall 12; all the first accommodating cavities 4 are arranged in a row along the length direction of the long side wall 12, and the connecting walls of the two concave groove plates 41 of each first accommodating cavity 4 are respectively connected to one of the long side walls 12 and the partition plate 14, and the connecting wall and the two groove walls are connected to the bottom plate; the outer side surface of each second accommodating cavity 5 is connected to one of the long side walls 12 and the partition plate 14, the bottom of the cavity wall of the second accommodating cavity 5 is connected to the bottom plate, and the bottom of the tenon column 6 is connected to the bottom plate.

[0035] Each concave groove plate member 41 further includes a transition portion 11 connected to the outside of one of the groove walls. The transition portion 11 is folded to form a vertical portion 15, a first horizontal portion 16, an inclined portion 17, and a second horizontal portion 18, which are sequentially connected. The first horizontal portion 16 connects the lower end of the vertical portion 15 and the lower end of the inclined portion 17. The upper end of the inclined portion 17 connects one end of the second horizontal portion 18, and the other end of the second horizontal portion 18 connects to the outside of the groove wall. Adjacent concave groove plates 41 are spaced apart. The vertical portion 15 of the transition portion 11 of each concave groove plate member 41 connects to the outside of one groove wall of the adjacent concave groove plate member 41. The transition portion 11 of each concave groove plate member 41 is connected to the long side wall 12 or the partition plate 14. The transition portion 11 is used to connect the groove walls of adjacent first accommodating cavities 4 in series to widen the connection area between the concave groove plate member 41 and the long side wall 12 and the partition plate 14. Gaps are provided between the concave groove plates 41 and are connected only by the transition portion 11 , which saves molding materials and reduces the cost of paper tray molding while ensuring structural strength.

[0036] The cavity wall of the second accommodating cavity 5 and the cavity wall of the first accommodating cavity 4 are partially hollowed out at the position connected to the long side plate and the partition plate 14 (position marked 13), forming hollow surfaces of different specifications to control the volume and weight of the actual container, avoid redundant structure to increase packaging costs, and ensure the lightweight characteristics and environmental protection of the packaging structure.

[0037] Both the first and second molds 1 and 2 have a square structure. Positioning slots are located at the four outer corners of the first mold 1, and matching positioning inserts 3 are located in the corresponding positions of the second mold. The matching positioning slots and positioning inserts 3 improve the positioning accuracy of the first and second molds 1 and 22 when they are sealed together, while further strengthening the connection between the first and second molds 1 and 22.

[0038] This paper tray container primarily utilizes a combination of a first mold shell 1 and a second mold shell 2 to package hardware components. The location and number of first cavities 4 are determined based on the actual individual packaging specifications. The first cavities 4 and second cavities 5 can be used to package small and medium-sized parts, respectively, facilitating grouped packaging planning for parts of varying specifications and enhancing the versatility of the paper tray container.

[0039] The side surfaces of the first accommodating cavity 4 and the second accommodating cavity 5 are formed with hollow surfaces of different specifications in the connection section with the first mold shell 1 to control the volume and weight of the actual container, avoid redundant structure to increase packaging costs, and ensure the lightweight characteristics and environmental protection of the packaging structure.

[0040] like Figure 2 、 3 As shown, the first accommodating cavity 4 mainly utilizes the relatively distributed concave groove plates 41 and the internal clamping plate 9 structure to clamp and fix parts. The parts can be arranged longitudinally in its accommodating cavity, or the middle groove space formed by the combination of multiple first accommodating cavities 4 (the gap between two rows of concave groove plates 41 used to embed the socket plate 8) is used to clamp and fix strip parts. It can clamp strip parts of various specifications, and finally it is limited by the socket plate 8 covered on the first accommodating cavity 4, thereby improving the packaging effect of the paper tray container.

[0041] like Figure 4 、 5 As shown, the second accommodating cavity 5 mainly utilizes a circular groove cavity to facilitate the filling of multiple parts, and the column groove cover 77 structure covered on the second accommodating cavity 5 is used to encapsulate the groove. Considering that the structural strength of the paper holder container is gradually affected by the size of the opening surface, the tenon column 6 extending from the bottom plate of the first mold shell 1 to the end of the second accommodating cavity 5 is used to increase the connection surface between the cavity wall and the first mold shell 1, thereby improving the strength of the cavity structure while avoiding limited packaging space.

[0042] Compared with the traditional method of using paper trays and plastic packaging for secondary packaging, this type of paper tray container improves the packaging effect and user experience of the container while controlling packaging costs.
