Technical Field

[0001] This utility model relates to the field of food packaging container technology, and in particular to a blister pack lunch box that is easy to open and close. Background Technology

[0002] Blister food containers are a common type of food packaging container, widely used in fast food delivery, fresh food packaging and other fields due to their advantages such as low cost, easy molding and good transparency.

[0003] Existing blister packs typically rely on friction between the lid and the edge of the container or a simple snap-fit ​​structure to achieve sealing and closing. However, because the blister material itself is thin and has a certain degree of flexibility, the lid is prone to deformation or misalignment when the user closes it, making it difficult to align precisely with the container on the first try. Often, repeated adjustments are needed to close it properly, resulting in a poor user experience.

[0004] What's even more inconvenient is that, to ensure a certain level of airtightness, this fitting structure is usually very tight. When it's necessary to open the lunchbox, the user must use their fingernail to pry open the edge of the lid, applying considerable external force. This method of opening is not only time-consuming and laborious, easily causing soup to splash out, but it is also particularly difficult for users with short nails or insufficient hand strength, seriously affecting the ease of use.

[0005] In summary, existing blister packs generally suffer from problems such as inconvenient lid alignment and difficulty in opening, lacking a structure that can balance quick alignment and closure with effortless and convenient opening.

[0021] 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.

[0022] Reference Figures 1-5 This utility model provides a blister food box that is easy to open and close, aiming to solve the problems of existing blister food boxes where the lid and box body are difficult to align precisely when closed, and the lack of auxiliary structures when opening, which makes opening difficult.

[0023] Specifically, it includes a protective box 1 and a protective cover 2 that can be opened and closed on the protective box 1. The protective box 1 serves as the main structure for containing items, and the protective cover 2 is used to close the opening of the protective box 1. The protective box 1 and the protective cover 2 together constitute the storage space of the lunch box.

[0024] It also includes an installation component 4 and a fixing component 3. The installation component 4 is used to guide the quick alignment and smooth opening and closing of the protective cover 2 and the protective box 1, and the fixing component 3 is used to realize the quick locking and unlocking between the protective cover 2 and the protective box 1.

[0025] The mounting assembly 4 includes an outer wall ring 402 and a sliding block 401. The outer wall ring 402 is fixedly connected to the outer wall of the protective box 1. A groove 403 is provided on the outer wall ring 402. The sliding block 401 is fixedly connected to the outer wall of the protective cover 2, and the sliding block 401 is slidably connected to the groove 403. Through the guiding movement of the sliding block 401 in the groove 403, it is ensured that the protective cover 2 can slide accurately to the predetermined closed position during the closing process.

[0026] The fixing component 3 includes a rubber plate 301, a pull handle 304, an ejector block 303, a sliding post 305, a rotating post 306, and a spring 307. The rubber plate 301 is rotatably connected to the protective cover 2 via the rotating post 306. The rubber plate 301 can rotate and engage in the groove of the outer wall ring 402, thereby locking the protective cover 2. The ejector block 303 is slidably connected to the sliding post 305. The pull handle 304 is connected to the ejector block 303. The spring 307 is sleeved on the sliding post 305. The pull handle 304 can drive the ejector block 303 to move. The movement of the ejector block 303 can push the rubber plate 301 out of the groove of the outer wall ring 402, thereby unlocking.

[0027] The fixing component 3 also includes a support strip 302, which is fixedly connected to the inner side of the rubber plate 301. When the rubber plate 301 is rotated to lock the protective cover 2, the support strip 302 and the rubber plate 301 can be inserted together into the groove of the outer wall ring 402. The setting of the support strip 302 increases the contact area and structural strength of the locking, so that the rubber plate 301 is subjected to more uniform force in the locked state, preventing the thin rubber plate 301 from undergoing excessive deformation, thereby ensuring the long-term stability and reliability of the connection between the protective cover 2 and the protective box 1.

[0028] The rotating column 306 is fixedly connected to the inside of the protective cover 2. This connection method, which places the fixed end of the rotating column 306 inside the protective cover 2, ensures that the outer surface of the protective cover 2 maintains a high degree of flatness and aesthetics, avoids the risk of scratches or damage that may be caused by exposed connection structures, and also protects the connection root between the rotating column 306 and the protective cover 2, thereby improving the durability of the overall structure.

[0029] One end of the sliding column 305 is fixedly connected to the protective cover 2, while the other end of the sliding column 305 is a free end, used to guide the reciprocating sliding of the ejector block 303. This cantilevered fixing structure not only simplifies the assembly process of the entire fixing component 3 and reduces the number of parts and installation steps, but also provides unobstructed space for the movement of the ejector block 303 and the spring 307, ensuring the smooth operation of the unlocking mechanism.

[0030] To achieve the automatic reset function after unlocking, the spring 307, as a reset element, is specifically sleeved on the outside of the sliding post 305. The two ends of the spring 307 abut against the ejector block 303 and the protective cover 2 respectively to fix the structure of the sliding post 305. When the handle 304 is pulled to drive the ejector block 303 to slide outward, the spring 307 is compressed and stores elastic potential energy. When the external force is removed, the spring 307 releases the stored energy and pushes the ejector block 303 and the handle 304 to automatically return to the initial position in opposite directions, so that the unlocking mechanism is always in a standby state.

[0031] When the ejector block 303 moves away from the handle 304, the front working surface of the ejector block 303 can abut against and push the rubber plate 301. In order to ensure effective transmission of thrust and smooth operation, the front working surface of the ejector block 303 can have a thrust curve that matches the contour of the force-bearing part of the rubber plate 301. This structure allows the ejector block 303 to apply force smoothly when pushing the rubber plate 301, avoiding stress concentration caused by point contact, and realizing a labor-saving and reliable unlocking process.

[0032] The groove 403 on the outer ring 402 extends circumferentially along the protective box 1, providing a circumferential sliding track for the sliding block 401. This design allows the user to close the protective cover 2 without precise radial alignment. Simply place the protective cover 2 roughly on the protective box 1, allowing the sliding block 401 to enter any position in the groove 403, and then push the protective cover 2 circumferentially to smoothly complete the closing and alignment, greatly simplifying the operation and improving ease of use.

[0033] Working principle: When the blister pack needs to be closed, the protective cover 2 is placed on the protective box 1. The sliding block 401 on the outer wall of the protective cover 2 will enter the groove 403 opened inside the outer wall ring 402 fixed on the outer wall of the protective box 1. Pushing the protective cover 2, the sliding block 401 will slide along the sliding trajectory provided by the groove 403, accurately guiding the protective cover 2 to the closed position. When the protective cover 2 reaches the appropriate position, rotate the rubber plate 301 that is rotatably connected to the protective cover 2. The rubber plate 301 rotates around the rotating column 306 and, together with the support strip 302 fixed on the rubber plate 301, is engaged in the groove of the outer wall ring 402, completing the fixing and locking of the protective cover 2.

[0034] When you need to open the blister pack, first pull the handle 304 outward. The handle 304 causes the ejector block 303 to slide outward on the outer wall of the sliding post 305. As the ejector block 303 slides, it compresses the spring 307 sleeved on the sliding post 305. At the same time, the moving ejector block 303 pushes the rubber plate 301 and support strip 302, which are already stuck in the groove, out of the groove of the outer wall ring 402, thereby releasing the lock on the protective cover 2. After releasing the pull of the handle 304, the ejector block 303 will be reset under the rebound action of the spring 307. At this time, pull the protective cover 2 outward. The protective cover 2 causes the sliding block 401 to slide inside the groove 403 of the outer wall ring 402, and the food box can be opened.
