Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art should fall within the protection scope of this utility model.
[0024] The strawberry packaging box of this utility model includes at least one unit packaging box A. Please refer to [link / reference]. Figures 1 to 4This is a preferred embodiment of the present invention. In this embodiment, the strawberry packaging box includes a unit packaging box A, which includes a bottom box 1, a top cover 2, and an inner liner 3. The bottom box 1, the inner liner 3, and the top cover 2 are stacked sequentially from bottom to top. The bottom box 1 has several recessed bottom box recesses 11. The inner liner 3 is stacked on the bottom box 1, and has several recessed inner liner recesses 31 at the corresponding positions of the bottom box recesses 11. The inner liner recesses 31 are located in the corresponding bottom box recesses 11. The bottom of the bottom box 1 has a downwardly protruding positioning boss 12, and the top of the top cover 2 has a downwardly recessed positioning groove 21 at the corresponding position of the positioning boss 12. The shape of the positioning groove 21 matches the shape of the positioning boss 12. The bottom of each inner liner recess 31 has a through hole (not shown in the figure), and there is a gap between the bottom of each inner liner recess 31 and the bottom of the corresponding bottom box recess 11.
[0025] Please refer to the following: Figure 5 When selling, displaying, or transporting strawberries, the above-mentioned unit packaging boxes A can be stacked one on top of the other. The positioning protrusion 12 at the bottom of the bottom box 1 of the upper unit packaging box A is located in the positioning groove 21 at the top of the top cover 2 of the lower unit packaging box A. The two unit packaging boxes A will not slide relative to each other, which can prevent the strawberry packaging boxes from collapsing and avoid damaging the strawberries.
[0026] like Figure 6 As shown, in other embodiments of this utility model, it is necessary to separate multiple boxes of strawberries ( Figure 6 The strawberry packaging (shown as two boxes) is sold or displayed as a set of products. The strawberry packaging includes a waist seal 4 and multiple unit packaging boxes A. The multiple unit packaging boxes A are stacked vertically, with the positioning protrusions 12 on the bottom box 1 of each unit packaging box A engaging with the positioning grooves 21 on the top cover 2 of the adjacent unit packaging box A below. The waist seal 4 encircles the outside of the strawberry packaging box. In this way, when multiple unit packaging boxes A are stacked, the waist seal 4 design provides enhanced stability, eliminating the need for additional cardboard boxes, solving the packaging problem, and reducing packaging costs.
[0027] In this embodiment, the positioning protrusions 12 are located on the bottom box 1 near the four corners, and the positioning grooves 21 are located on the top cover 2 near the four corners. Both the positioning protrusions 12 and the positioning grooves 21 are "L"-shaped. It can be understood that the position, number, and shape of the positioning protrusions 12 and the positioning grooves 21 are not limited to the above embodiment, as long as they can form a concave-convex fit. As another embodiment of this utility model, the positions of the positioning protrusions and positioning grooves can be interchanged, that is, a positioning groove that is recessed upward is provided at the bottom of the bottom box 1, and a positioning protrusion that protrudes upward at the position corresponding to the positioning groove on the top of the top cover 2. When selling, displaying, or transporting strawberries, the unit packaging boxes A are stacked one on top of the other. The positioning protrusion on the top cover 2 of the lower unit packaging box A is located in the positioning groove at the bottom of the bottom box 1 of the upper unit packaging box A. The two unit packaging boxes A will not slide relative to each other, which can also prevent the strawberry packaging boxes from collapsing and avoid damaging the strawberries.
[0028] To easily distinguish the placement direction of the strawberries, the aforementioned unit packaging box A is quadrilateral, with a chamfer 13 at one corner of the bottom box 1. The top cover 2 and the inner lining 3 also have chamfers 22 and 32 respectively, corresponding to the chamfer 13 on the bottom box 1. In this embodiment, unit packaging box A is rectangular, with chamfers 13, 22, and 32 located at the lower left corner of unit packaging box A, indicating the direction the pointed end of the strawberry is facing. This makes the placement direction of the strawberries immediately clear.
[0029] The aforementioned top cover 2 has a top wall 23 and side walls 24, with the side walls 24 extending downwards from the periphery of the top wall 23. Multiple horizontally protruding flanges 241 are located at the bottom of the side walls 24, which, when engaged with the bottom box 1, ensure a stable fit between the top cover 2 and the bottom box 1. A certain distance exists between the top wall 23 of the top cover 2 and the bottom of the inner lining recess 31, this distance being greater than the maximum outer diameter of the strawberry. Thus, when the strawberry is placed in the inner lining recess 31, a gap exists between the top wall 23 of the top cover 2 and the strawberry, preventing damage to the strawberry from contact with the top wall 23. To prevent the top wall 23 of the upper cover 2 from collapsing and damaging the strawberries due to external forces, in this embodiment, multiple bottom box protrusions 14 extend vertically upward from the bottom box 1. The bottom box protrusions 14 are located between the bottom box recesses 11. The inner liner 3 also has upwardly protruding inner liner protrusions 33 at the corresponding positions of the bottom box protrusions 14. The inner contour shape of the inner liner protrusions 33 is consistent with the outer contour of the bottom box protrusions 14, and they are fitted onto the bottom box protrusions 14. The upper cover 2 has a downwardly protruding upper cover protrusion 25 at the corresponding positions of the bottom box protrusions 14, and the bottom of the upper cover protrusion 25 abuts against the top of the bottom box protrusions 14. In this way, the abutment between the upper cover protrusion 25 and the bottom box protrusions 14 can enhance the strength of the top wall 23 of the upper cover 2 and prevent the top wall 23 of the upper cover 2 from collapsing.
[0030] The aforementioned inner liner 3 can be made of a soft membrane to provide shock absorption. To ensure the inner liner 3 is stably stacked on the bottom box 1, in this embodiment, several bottom box positioning protrusions 15 protrude upwards near the periphery of the bottom box 1. Corresponding to the positions of the bottom box positioning protrusions 15, the inner liner 3 has upward-protruding inner liner positioning protrusions 34. The inner contour shape of the inner liner positioning protrusions 34 matches the outer contour shape of the bottom box positioning protrusions 15, and they fit snugly onto the bottom box positioning protrusions 15. Thus, through the cooperation between the inner liner positioning protrusions 34 and the bottom box positioning protrusions 15, and the cooperation between the inner liner protrusions 33 and the bottom box protrusions 14, the inner liner 3 can be prevented from moving freely within the bottom box 1, thereby better protecting the strawberries.
[0031] To improve the preservation performance of strawberries, the aforementioned strawberry packaging box employs a safer non-contact preservation method. Specifically, the aforementioned unit packaging box A also includes a preservative sheet (not shown in the figure), which is located within one of the bottom box recesses 11 and in the gap between the inner lining recess 31 and the bottom box recess 11. In this way, the preservative gas emitted from the preservative sheet can enter the inner lining recess 31 through the through-holes on the inner lining 3, thereby providing a preservative environment for the strawberries and achieving the effect of preservation.
[0032] This utility model's strawberry packaging box utilizes the interlocking positioning protrusion 12 / positioning groove at the bottom of the base box 1 and the positioning groove 21 / positioning protrusion at the top of the adjacent top cover 2. This prevents the stacked unit packaging boxes A from collapsing, thus avoiding damage to the strawberries. When multiple boxes of strawberries need to be sold or displayed as a set, a waist seal 4 can be added for further reinforcement, solving packaging problems while reducing packaging costs. Furthermore, the chamfered corners 13, 22, and 32 on the unit packaging box A facilitate differentiation of the strawberry placement direction, increasing the convenience and aesthetics of the strawberry packaging. Placing the preservative sheet in the gap between the inner lining recess 31 and the bottom box recess 11 achieves non-contact preservation of the strawberries, ensuring freshness and making them safer to eat.
[0033] The above embodiments are merely preferred embodiments of the present utility model, but the implementation of the present utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered as equivalent substitutions and shall be included within the protection scope of the present utility model.
