Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic products, in particular to a self-locking sushi box. Background Art
[0002] Sushi is a dish made by kneading rice balls and side dishes together, usually in a square or cylindrical shape. Currently, in the delivery mode of takeout or package delivery, sushi is usually packaged in plastic boxes, which are the square or disc-shaped sushi boxes that are more common in takeout.
[0003] Traditional sushi boxes typically feature a lid covering a base, with the lid sliding down over the base. The drawbacks of these traditional sushi boxes include: the lid is easily opened, allowing liquids or dust to enter and contaminate the food. Furthermore, there are occasional cases of food being partially missing or maliciously contaminated, compromising the integrity and food safety of the food during transportation. This can reduce customer confidence in the product and discourage purchases. Utility Model Content
[0004] Based on this, the utility model provides a self-locking sushi box, which adopts a sliding cover, and a ratchet structure is set on both sides of the cover and the bottom box, and cooperates with a breakable stop plate to achieve self-locking between the cover and the bottom box. It can be unlocked by simply breaking the stop plate, ensuring the integrity of the food and food safety during transportation. Customers can know whether the food has been unpacked in advance according to whether the stop plate is broken, thereby increasing customers' trust in the product and purchasing desire.
[0005] A self-locking sushi box, comprising:
[0006] The bottom box is a square trough; a first convex strip is provided on each side of the bottom box; the first convex strip is arranged in a horizontal direction and has a plurality of evenly spaced first convex teeth; the first convex teeth are a right triangle structure with the hypotenuse facing outward; a stop plate is provided at one end of the bottom box; a plurality of evenly spaced hollow portions are provided at the bottom of the stop plate; and
[0007] A surface cover is slidably connected to the bottom box; the surface cover is a square cover body; a second convex strip is provided on each side of the surface cover; a sliding groove is provided on the inner side of the second convex strip to be slidably connected to the first convex strip; and the second convex strip is also provided with a plurality of second convex teeth evenly spaced in the sliding groove, and the second convex teeth are a right-angled triangle structure with the hypotenuse facing inward; the second convex teeth abut against the first convex teeth; one end of the surface cover abuts against the inner side of the stop plate.
[0008] In the self-locking sushi box, after the food is placed in the bottom box, the cover is slid in from the end of the bottom box where the stop plate is not provided. During the sliding process of the cover, the second protruding teeth in the sliding groove of the cover collide with the first protruding teeth on the first protruding strip of the bottom box, forming a ratchet structure similar to a cable tie. Whenever the second protruding teeth collide with the first protruding teeth, the external force pushing the cover forces the second protruding teeth to pass over the first protruding teeth until the end of the cover contacts the stop plate. Since the first and second protruding teeth block each other, the cover cannot move backward, thereby achieving the purpose of self-locking. When it is necessary to remove the food, the customer only needs to bend the stop plate in the sliding direction of the cover, forcing the area of the stop plate with the hollow portion to break. The customer can then remove the stop plate and slide the cover forward to separate the cover from the bottom box, achieving the purpose of removing the food. Through the above design, a sliding cover is adopted, and ratchet structures are set on both sides of the cover and the bottom box, and a breakable stop plate is used to achieve self-locking between the cover and the bottom box. Moreover, it can be unlocked by simply breaking the stop plate, thereby ensuring the integrity and food safety of the food during transportation. Customers can know whether the food has been unpacked in advance based on whether the stop plate is broken, thereby increasing customers' trust in the product and their desire to buy.
[0009] In one embodiment, the bottom of the inner cavity of the bottom box is provided with a plurality of raised portions arranged in an array. When sushi is placed in the bottom box, the raised portions can be used to prop up the sushi, creating a gap between the bottom of the sushi and the bottom of the inner cavity of the bottom box. This reduces the risk of the bottom of the sushi sticking to the bottom of the bottom box, making it easier for customers to take the sushi out.
[0010] In one embodiment, a plurality of spaced partitions are provided at the bottom of the inner cavity of the bottom box. The partitions can divide the inner cavity of the bottom box into sections, making it easier for merchants to place different types of sushi in different areas, improving the aesthetics of the plating, and further enhancing the stability of the plating during transportation.
[0011] In one embodiment, the ends of the stopper plate extend outside the face cover. When the customer needs to break the stopper plate, they can first grab the ends of the stopper plate and move it forward to create a gap between the stopper plate and the face cover. Then, they can grab the middle of the stopper plate to apply force to break the stopper plate.
[0012] In one embodiment, both ends of the stop plate are rounded structures. This design can reduce the risk of the stop plate scratching through the packaging bag and improve the integrity of the packaging during the delivery process.
[0013] In one embodiment, the top cover is a transparent cover, which allows customers to intuitively see the status of the food in the bottom box.
[0014] In one embodiment, a mark for marking the closing direction is provided on the top surface of the cover. The mark allows merchants to quickly determine the closing direction of the cover, thereby improving the efficiency of serving food. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0030] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0031] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
[0032] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0033] like Figures 1 to 8 As shown, it is a self-locking sushi box 100 according to an embodiment of the present invention.
[0034] like Figures 1 to 3 As shown, the self-locking sushi box 100 comprises a base box 10 and a cover 20 that slides into and out of the base box 10. The base box 10 is used to hold food, while the cover 20 seals the opening of the base box 10, forming a storage cavity for protecting the food. During use, the cover 20 slides horizontally onto the base box 10.
[0035] Below, combined Figures 1 to 8 , the self-locking sushi box 100 is further described.
[0036] like Figure 5 and Figure 6 As shown, the bottom box 10 is a square trough. When serving food, the food is placed in the inner cavity of the bottom box 10. The two sides of the bottom box 10 are respectively provided with first ridges 11. Figure 4 As shown, the first convex strip 11 is arranged in the horizontal direction, and the first convex strip 11 is provided with a plurality of first convex teeth 111 evenly spaced. The first convex teeth 111 are a right triangle structure with the hypotenuse facing outward. For example, in this embodiment, each side of the bottom box 10 is provided with three first convex teeth 111, distributed at both ends and the middle of the bottom box 10. Figure 5 and Figure 6 As shown, a stopper plate 12 is provided at one end of the bottom box 10. The bottom of the stopper plate 12 is provided with a plurality of hollow portions 121 evenly spaced. Figure 6As shown, in this embodiment, the hollow portion 121 is a plurality of through holes distributed along a straight line.
[0037] Considering that the surface of food usually has a certain degree of stickiness, for example, the rice of sushi is usually in a wet state, so the rice is easy to stick to the bottom surface of the bottom box 10. When the customer takes out the sushi, the rice may be pulled apart, causing the food to be damaged. Figure 5 As shown, in this embodiment, the bottom of the inner cavity of the bottom box 10 is provided with a plurality of raised portions 13 distributed in an array (for ease of demonstration, in this embodiment, the raised portions 13 are strip-shaped raised portions; in other embodiments, the raised portions 13 may also be raised dots, square convex blocks, or irregularly shaped convex blocks). When sushi is placed in the bottom box 10, the raised portions 13 can be used to lift the sushi so that there is a gap between the bottom of the sushi and the bottom of the inner cavity of the bottom box 10, thereby reducing the chance of the bottom of the sushi sticking to the bottom of the bottom box 10 and making it easier for customers to take the sushi out.
[0038] In addition, in order to make the food presentation more neat and avoid the food from being disturbed due to large displacement caused by shaking during the delivery process. Figure 5 As shown, in this embodiment, a plurality of spaced partitions 14 are provided at the bottom of the inner cavity of the bottom box 10. The partitions 14 can divide the inner cavity of the bottom box 10 into zones, making it easier for merchants to place different types of sushi in different zones, improving the aesthetics of the plating, and further enhancing the stability of the plating during transportation.
[0039] like Figure 7 As shown, the cover 20 is a square cover. A second ridge 21 is provided on both sides of the cover 20. Figure 8 As shown, the inner side of the second ridge 21 is provided with a sliding groove 211 for slidingly connecting the first ridge 11. Figure 4 As shown, the second convex strip 21 is further provided with a plurality of second protruding teeth 212 evenly spaced and distributed in the chute 211. The second protruding teeth 212 are a right triangle structure with the hypotenuse facing inward. The second protruding teeth 212 abut against the first protruding teeth 111. For example, in this embodiment, the number of the second protruding teeth 212 is the same as the number of the first protruding teeth 111, and the distribution positions are staggered. Figure 1 As shown, one end of the face cover 20 abuts against the inner side of the stop plate 12 .
[0040] In this embodiment, the cover 20 may be a transparent cover, which allows customers to visually see the status of the food in the bottom box 10.
[0041] Brief description of working principle:
[0042] Combine Figure 1 、 Figure 2 ,as well as Figure 4As shown, after the food is placed in the bottom box 10, the cover 20 is slid in from the end of the bottom box 10 where the stop plate 12 is not provided. During the sliding process of the cover 20, the second protruding teeth 212 in the sliding groove 211 of the cover 20 collide with the first protruding teeth 111 on the first protruding strip 11 of the bottom box 10, forming a ratchet structure similar to a cable tie. Whenever the second protruding teeth 212 collide with the first protruding teeth 111, the external force pushing the cover 20 forces the second protruding teeth 212 to pass over the first protruding teeth 111 until the end of the cover 20 abuts the stop plate 12. Since the first protruding teeth 111 and the second protruding teeth 212 are mutually blocked, the cover 20 cannot move back, thereby achieving the purpose of self-locking. When the customer needs to take out the food, he or she only needs to bend the stopper plate 12 in the sliding direction of the cover 20, forcing the area of the stopper plate 12 where the hollow portion 121 is provided to break. The customer can then remove the stopper plate 12 and slide the cover 20 forward to separate the cover 20 from the bottom box 10, thereby taking out the food. In this solution, the bottom box 10 can be made of a plastic with a slightly higher hardness, while the cover 20 can be made of a plastic with a slightly lower hardness and a slight degree of elasticity.
[0043] like Figure 1 and Figure 2 As shown, to facilitate the removal of the cover 20 by the customer, in this embodiment, both ends of the stopper plate 12 extend outside the cover 20. When the customer needs to break the stopper plate 12, they can first grasp the ends of the stopper plate 12 and then move it forward to create a gap between the stopper plate 12 and the cover 20. Then, they can grasp the middle of the stopper plate 12 to apply force to break the stopper plate 12.
[0044] Furthermore, if Figure 5 and Figure 6 As shown, in this embodiment, both ends of the stop plate 12 are rounded structures. This design can reduce the risk of the stop plate 12 scratching the packaging bag and improve the integrity of the packaging during the delivery process.
[0045] In addition, in order to allow merchants to quickly identify the correct sliding direction of the cover 20, such as Figure 1 and Figure 7 As shown, in this embodiment, a mark 22 for marking the closing direction is provided on the top surface of the cover 20 (for example, in this embodiment, the mark 22 is an arrow). The mark 22 facilitates merchants to quickly determine the closing direction of the cover 20, thereby improving meal serving efficiency.
[0046] The above-mentioned self-locking sushi box 100 adopts a sliding cover 20, and a ratchet structure is set on both sides of the cover 20 and the bottom box 10, and cooperates with a breakable stop plate 12 to achieve self-locking between the cover 20 and the bottom box 10. It can be unlocked by simply breaking the stop plate 12, ensuring the integrity and food safety of the food during transportation. Customers can know whether the food has been unpacked in advance based on whether the stop plate 12 is broken, thereby increasing customers' trust in the product and their desire to buy.
[0047] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
