Description

Technical Field

[0001] This utility model belongs to the technical field of packaging boxes, specifically relating to a glue-free snack carrying box structure. Background Technology

[0002] Currently, most ready-to-eat snack packaging boxes on the market are glued or taped together (such as the existing patent solution with announcement number CN217456764U). On the one hand, because the load-bearing capacity of such glue or tape bonding structures is limited, the bonding joints are prone to falling off, causing ready-to-eat snacks to scatter and resulting in losses for customers. On the other hand, glue and tape are not environmentally friendly, and packaging boxes containing glue or tape are prone to causing pollution. Moreover, glue and tape easily attract dust, which can indirectly contaminate the ready-to-eat snacks inside the packaging box. Utility Model Content

[0004] In one specific embodiment, the bottom plate, left side plate, right side plate, front side plate, and rear side plate are all made of cardboard material.

[0005] In one specific embodiment, extension plates are connected to both sides of the first rocker arm via creases, and the first tongue is disposed at the free end of the extension plate.

[0006] In one specific embodiment, the first tongue has a structure that is wide in the middle and narrow at both ends, and the widest position of the first tongue is greater than the length of the insertion slot.

[0007] In one specific embodiment, the first tongue is formed by a superior arc and the edge of the extension plate, and the diameter corresponding to the superior arc is greater than the length of the insertion slot.

[0008] In one specific embodiment, the insertion slot has a basin-shaped structure.

[0009] In one specific embodiment, the second tongue is disposed on the side of the handle, the second tongue extends toward the top of the handle, and the second tongue forms an acute angle with the side of the handle.

[0010] In one specific embodiment, dustproof plates are connected to both sides of the first flap, and the dustproof plates are formed by a curved section enclosing the edge of the first flap.

[0011] In one specific embodiment, the perforation is crescent-shaped.

[0012] In one specific embodiment, the top edge of the handle is configured as an arc-shaped edge that matches the crescent-shaped perforation.

[0013] This utility model has at least the following beneficial effects: The technical solution adopts a glue-free design, which is more environmentally friendly and less likely to contaminate the food inside the carrying case. Furthermore, the overall structure adopts a one-piece design, making it easy to fold, and the first tongue engages with the slot, while the second tongue engages with the hole, significantly improving the overall load-bearing capacity.

Detailed Implementation

[0019] Please see Figures 1-4This utility model provides a glue-free snack box structure, including a base plate 1. The four edges of the base plate 1 are respectively connected to a left side plate, a right side plate, a front side plate, and a rear side plate. The base plate 1, left side plate, right side plate, front side plate, and rear side plate are all made of cardboard. The left side plate and right side plate are mirror-symmetrical in structure, each including a first flap 2, a first flap 3, and a handle 4 connected sequentially by folds. The front side plate and rear side plate are also mirror-symmetrical in structure, each including a second flap 5 and a second flap 6 connected by folds. Extension plates 7 are connected to both sides of the first flap 2 by folds. The free end of the extension plate 7 is provided with a first tongue 71, and the second flap 5 is provided with a slot 8 that engages with the first tongue 71. The first tongue 71 is formed by a curved section and the edge of the extension plate 7. The diameter of the curved section is greater than the length of the slot 8, resulting in a structure that is wider in the middle and narrower at both ends. Furthermore, the widest point of the first tongue 71 is greater than the length of the slot 8, ensuring that the first tongue 71, once inserted into the slot 8, forms an inverted snap-fit ​​structure and will not come loose. The slot 8 is designed in a basin shape, which makes the engagement between the first tongue 71 and the slot 8 increasingly tighter when the first tongue 71 bears the weight of the ready-to-eat snack. A second tongue 41 is provided on the handle 4, and a socket 9 is provided on the second cover 6 to engage with the second tongue 41. The second tongue 41 is located on the side of the handle 4, extending towards the top of the handle 4, and forms an acute angle with the side of the handle 4. Under the weight of the ready-to-eat snack and the force applied by the user when carrying it, the engagement between the second tongue 41 and the socket 9 will be even tighter and more secure. Dustproof plates 31 are connected to both sides of the first flap 3. The dustproof plate 31 is formed by an arc that surrounds the edge of the first flap 3. When folded, the dustproof plate 31 is folded inside the second flap 6 to prevent dust from entering the case through the gap between the first flap 3 and the second flap 6. The handle 4 has a perforated hole 42, which is crescent-shaped, making it convenient for the user to carry the case. The top edge of the handle 4 is set as an arc-shaped edge 43 that matches the crescent-shaped perforated hole 42, making it more comfortable for the user to carry the case.

[0020] In use, first fold the left and right side panels upright relative to the base plate 1, fold the extension plates 7 on both sides of the first rocker 2 and attach them to the outside of the second rocker 5, forcefully insert the first tongue 71 at the free end of the extension plate 7 into the corresponding slot 8, then fold the first cover 3 and the handle 4 so that the dustproof plates 31 on both sides of the first cover 3 are folded into the inside of the second cover 6, and insert the second tongue 41 on the handle into the socket 9 on the second cover 6, thus completing the installation of the glue-free snack box structure.

[0021] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
