Detailed Implementation
[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0032] Please see Figure 1 , Figure 1 A perspective view of an embodiment of the all-paper inner tray of this utility model is shown. The all-paper inner tray is made entirely of paper. The all-paper inner tray includes an upper paper card, a lower paper card, a front display screen protective plate, a left fixing block, and a right fixing block. The upper paper card, lower paper card, front display screen protective plate, left fixing block, and right fixing block are obtained by folding or snapping together cardboard after being molded. When the all-paper inner tray is assembled into the packaging box body, the upper paper card abuts against the top of the front display screen protective plate, the lower paper card abuts against the bottom of the front display screen, the left fixing block is located at the left end of the front display screen and abuts against the left ends of both the upper and lower paper cards; the right fixing block is located at the right end of the front display screen and abuts against the right ends of both the upper and lower paper cards.
[0033] Among them, such as Figure 2 As shown, the lower side of the upper paper card has a first groove adapted to the shape of the top of the product, which is used to engage and fix the top of the product. The first groove of the upper paper card has multiple interlocking holes along its circumference, which are used to mechanically interlock with buttons and / or interfaces on the top of the product. Specifically, they can mechanically interlock with specific parts of the product (such as buttons or interfaces) to prevent the product from sliding due to vibration during transportation. Figure 3As shown, the upper side of the upper paper card is a side with a first concave structure in the middle of the surrounding protrusions; the first concave structure has multiple protruding strips protruding from the outer surface of the first concave structure, and the protruding strips are used to enhance compressive strength. The protruding strips on the first concave structure are formed by folding the corrugated paper after die stamping. In this embodiment of the present invention, the upper side of the lower paper card is provided with a second groove adapted to the shape of the bottom of the product, for locking and fixing the bottom of the product. The structure of the lower paper card is the same as that of the upper paper card, and will not be described again here.
[0034] like Figure 4 As shown, the right side of the left fixing block has a third groove that matches the shape of the left side of the product. The left fixing block is placed vertically above the left end of the lower paper tray. The position of the third groove corresponds to the positions of the second groove on the lower paper tray and the first groove on the upper paper tray, allowing them to nest together along the left edge of the product. For example... Figure 5 As shown, the left and right fixing blocks are formed by folding the entire corrugated cardboard sheet inward from both sides to the center after die stamping, creating a third and fourth groove in the middle. The heights of the left and right fixing blocks, the lengths of the third and fourth grooves are the same as the height of the front display screen protective plate. The left side of the right fixing block has a fourth groove that matches the shape of the right side of the product. Since the structures of the left and right fixing blocks are symmetrical, the structure of the right fixing block will not be described further here.
[0035] like Figure 6 As shown, a protective block is provided on the first surface of the front display screen protection plate to protect the product's display screen when it comes into contact with it. Multiple protective blocks are vertically arranged and laterally distributed along the first surface of the front display screen protection plate; the height of the protective blocks is the same as the height of the front display screen protection plate. There are three protective blocks, respectively distributed at the left, middle, and right ends of the first surface of the front display screen protection plate, thereby providing better protection for the product's display screen. The protective block can be hollow, meaning it can be formed by folding and snapping together cardboard.
[0036] In this embodiment of the invention, when the full tray paper assembly is placed inside the packaging box body, the upper tray paper abuts against the top of the front display screen protective plate, and the lower tray paper abuts against the bottom of the front display screen. The left fixing block is located at the left end of the front display screen and abuts against the left ends of both the upper and lower tray paper cards; the right fixing block is located at the right end of the front display screen and abuts against the right ends of both the upper and lower tray paper cards. The top of the product engages in the first groove of the upper tray paper card, the left side of the product engages in the third groove of the left fixing block, the right side of the product engages in the fourth groove of the right fixing block, and the bottom of the product engages in the second groove of the lower tray paper card. The product's display screen is attached to the protective block on the front display screen protective plate. After assembling the various parts around the product, the assembled structure is placed inside the corresponding packaging box body. The size of the packaging box body is consistent with the length, width, and height of the assembled structure after the various parts are assembled around the product, thereby fixing and supporting the product when the assembled structure is placed inside the packaging box body, thus maintaining shock absorption and drop prevention.
[0037] This embodiment of the utility model features an all-paper inner tray made entirely of paper. The all-paper inner tray includes an upper paper card, a lower paper card, a front display screen protective plate, a left fixing block, and a right fixing block. The upper paper card, lower paper card, front display screen protective plate, left fixing block, and right fixing block are obtained by folding or snapping together cardboard after being molded. When the all-paper inner tray is assembled inside the packaging box, the upper paper card abuts against the top of the front display screen protective plate, the lower paper card abuts against the bottom of the front display screen, the left fixing block is located at the left end of the front display screen and abuts against the left ends of both the upper and lower paper cards, and the right fixing block is located at the right end of the front display screen and abuts against the right ends of both the upper and lower paper cards. This modular design simplifies the overall complexity of the inner tray, replaces traditional plastic blister packs, and is environmentally friendly, maintaining shock absorption and drop protection while allowing the entire packaging box to be made of paper.
[0038] In another embodiment of this utility model, a packaging box is also provided, the packaging box including a packaging box body and the aforementioned all-paper inner tray; the all-paper inner tray is assembled inside the packaging box body for fixing and cushioning the product. The specific structure of the all-paper inner tray is largely the same as that of the all-paper inner tray in the above embodiment, and will not be described again here.
