Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food packaging technology, specifically relating to a biscuit packaging box. Background Technology
[0002] The core design concept of existing biscuit packaging boxes is almost entirely based on "disposable packaging". Once the biscuits inside are eaten, the entire packaging box loses its core use value and is thus discarded by consumers, generating a large amount of solid waste. Moreover, for consumers, a well-structured and sturdy box cannot be reused due to its single function, which also results in substantial waste.
[0003] Because the lid and the box body are physically independent and unconnected, the lid is removed and completely separated from the box body during the initial use or subsequent storage. At this time, the separated lid, as an independent, small component that lacks any physical connection or directional guidance with the box body, is very easy to lose. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] like Figures 1 to 5 The biscuit packaging box shown includes a box body 1 and a lid 2 that cooperates with the box body 1. A latch 11 extends outward from the top of the box body 1, and a first retaining ring 12 extends inward from the top inner side of the latch 11, forming a retaining groove 13 between the first retaining ring 12 and the latch 11. A retaining plate 21, which matches the retaining groove 13, extends upward from the top outer edge of the lid 2, and a second retaining ring 22 extends outward from the top outer side of the retaining plate 21. The bottom of the lid 2 is recessed upward. Mounting slot 23, with magnetic attachment 24 inside; multiple first recesses 3 are provided on the front and rear side walls of box 1, and multiple second recesses 4 are provided on the left and right side walls of box 1; the recessed surface of the first recesses 3 is flush with the horizontal plane of the side wall of box 1; the top surface of the second recesses 4 is an arc shape with a lower center and a higher outer side; the magnetic attachment 24 is a soft magnetic sticker; a concave-convex ring 14 is provided at the bottom of box 1; the outer contours of box 1 and cover 2 are both rounded.
[0026] This invention utilizes the cooperation of the card plate 21 and the card slot 13, as well as the interlocking of the first card ring 12 and the second card ring 22, to form a double sealing structure, ensuring the tightness of the lid when closed, effectively preventing moisture and dust, and realizing its basic storage function. After the biscuits inside are consumed, the sturdy box body 1 and the lid can be reused immediately as a storage box for storing stationery, jewelry, dried goods and other small items, extending the product's lifespan. The soft magnet built into the bottom of the lid body 2 allows the lid to be independently attached to any ferrous surface, becoming an independent magnetic storage unit, expanding the product's application scenarios. It can be used in various environments such as kitchens, offices, and workshops, meeting users' diverse storage needs.
[0027] Example 2
[0028] like Figures 1 to 5 The biscuit packaging box shown consists of a rectangular box body 1 and a lid 2. A retaining ring 11 extends outward from the top of the lid 2, and a first retaining ring 12 extends upward from the inner side of the retaining ring 11. A retaining groove 13 is formed between the first retaining ring 12 and the retaining ring 11, which surrounds the opening of the box. At the same time, a retaining plate 21 extends upward from the outer edge of the top of the box body, and a second retaining ring 22 extends from the outer side of the top of the retaining plate 21. When the lid 2 is closed, the retaining plate 21 of the lid 2 is precisely inserted into the retaining groove 13 of the box body 1. At the same time, the second retaining ring 22 and the first retaining ring 12 are interlocked to form a double seal. This structure ensures the tightness of the lid when it is closed, effectively preventing moisture and dust. It can be opened with only a little force. After the original filling inside has been consumed, the entire biscuit packaging box can be used for storage and can be reused.
[0029] The lid 2 features a recessed mounting groove 23 at its bottom, within which a magnetic element 24 (a soft magnet) is installed. This allows the lid 2 to be directly attached to any ferrous surface, such as a refrigerator door, filing cabinet, or magnetic whiteboard. When the lid is removed from the box 1, it instantly transforms into a standalone magnetic storage box for storing small office supplies like thumbtacks and paper clips; or it can be used as a spice box in the kitchen, attaching to the refrigerator side wall to save countertop space. When not in use, simply return the lid 2 to its original position on the box 1, seamlessly switching between functions.
[0030] Multiple first recesses 3 are designed on the front and rear side walls of the box body 1. The surface of the recesses smoothly transitions with the plane of the side walls, providing a natural point of force for the thumb, making it easier and more comfortable to open the lid. At the same time, multiple second recesses 4 are distributed on the left and right side walls of the box body 1. The top surface adopts an arc design that is low in the middle and high on the outer side, which not only increases the aesthetics of the box body 1, but also further improves the fit and stability when holding it.
[0031] The bottom of the box 1 is designed with a concentric circle-shaped concave-convex ring 14 structure, which consists of at least three alternating raised and recessed rings from the outside to the inside. This can effectively increase the friction between the box and surfaces such as the table, prevent slippage, and ensure stability when placed.
[0032] All outer corners of the box body 1 and the lid body 2 are rounded, with soft and smooth lines, effectively avoiding accidental bumps that may be caused by sharp corners, making it especially suitable for families with children.
[0033] Furthermore, such as Figure 6 As shown, the top of the lid 2 can also be raised with a pull ring pattern, reminiscent of the crisp and neat action of opening a can or beverage. When the thumb is located in the pull ring recess, it can feel a clear height difference and contour with the surrounding area, providing a tactile anchor point for the thumb and enabling precise blind operation.
[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
