Description

Technical Field

[0001] This utility model relates to the field of blister food box technology, and in particular to a blister food box with an anti-slip structure. Background Technology

[0002] Blister food containers are a common type of fast food packaging container, widely used in the catering industry, especially in the takeout and fast food sectors, due to their low cost, lightweight nature, and ease of production.

[0003] In practical applications, whether food is prepared centrally in the kitchen of a merchant, in the delivery box of a food delivery person, or stored in the refrigerator of a consumer, multiple food containers usually need to be stacked in order to save space and improve efficiency.

[0004] However, existing blister packs are often designed with a greater emphasis on sealing and basic containment. The top surface of the lid and the bottom surface of the base are typically designed to be flat or have large areas of smooth curves.

[0005] When multiple food containers with smooth contact surfaces are stacked together, the friction between the containers is low, resulting in poor connection stability. Bumps and shaking during transportation, or even slight collisions during handling, can easily cause the upper containers to slide and misalign horizontally. This unstable stacking not only increases the difficulty of organizing the containers, but more seriously, if the misalignment is too great, the entire stack of containers may lose balance and tip over, causing food spillage, damage to the containers, and inconvenience and financial losses for both businesses and consumers.

[0006] Therefore, this utility model proposes a blister pack with an anti-slip structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a blister pack with an anti-slip structure, aiming to improve the problem in the prior art where the smooth contact surfaces between the blister packs make the connection unstable when stacked, easily leading to sliding and tipping.

[0008] To achieve the above objectives, this utility model provides a blister food box with an anti-slip structure, including: a base, and an upper cover that can be detachably engaged with the base, as well as an anti-slip mechanism and a multi-functional anti-scalding mechanism.

[0009] The top surface of the upper cover is recessed to form a circular groove and an annular groove for the anti-slip mechanism, and the bottom wall of the chassis is integrally formed with a raised foot and an annular base that cooperate with the anti-slip mechanism.

[0010] Furthermore, the raised bottom foot is adapted to the position and shape of the circular groove, and the annular base is adapted to the position and shape of the annular groove, so that the upper and lower lunch boxes can be stably matched through structural nesting when stacked. The multi-functional anti-scalding mechanism is provided on the outer wall of the chassis, and the multi-functional anti-scalding mechanism includes a wave-shaped protrusion integrally formed on the outer wall.

[0011] Preferably, the internal partition of the chassis is formed as a first inner cavity and a second inner cavity.

[0012] Preferably, the first inner cavity and the second inner cavity are integrally reinforcedly connected by a connecting plate.

[0013] Preferably, the annular groove is concentrically surrounding the outer periphery of the circular groove.

[0014] Preferably, the annular base is concentrically surrounded by the outer periphery of the raised foot.

[0015] Preferably, the multifunctional anti-scalding mechanism further includes an inner convex ring, which is integrally formed on the upper edge of the opening of the chassis and extends toward its inner cavity.

[0016] Preferably, the edge of the upper cover extends integrally to form a convex corner.

[0017] Preferably, the wavy protrusions are distributed in a circumferential array on the outer walls of the first inner cavity and the second inner cavity.

[0018] This utility model has the following beneficial effects: 1. In this utility model, by setting a groove structure on the top surface of the cover and a corresponding protrusion structure that can be nested and engaged with it on the bottom of the base, the problem of unstable connection due to the smooth contact surface of existing blister lunch boxes during batch stacking is solved, which easily leads to sliding, misalignment or even tipping during transportation or storage. This achieves the effect of enhancing stacking stability and preventing slippage and tipping.

[0019] 2. This utility model solves the problems of existing lunch boxes having high wall temperatures after hot food is placed inside, posing a risk of scalding, and the smooth surface easily slipping after being contaminated with oil or moisture. It achieves the dual functions of heat insulation and anti-scalding, as well as grip and anti-slip, thus improving the safety of use. Attached Figure Description

[0022] 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.

[0023] Reference Figures 1-5 This utility model provides a blister food box with an anti-slip structure, which aims to solve the problems of poor stability when stacking existing blister food boxes, easy sliding and tipping, and the risk of scalding hands and slipping when holding hot food.

[0024] Specifically, it includes a chassis 2 and a top cover 1 that can be detachably engaged with the chassis 2. The chassis 2 serves as the main body for containing food, and the top cover 1 is used to seal the chassis 2. Through the tight fit between the top cover 1 and the chassis 2, the food inside is protected and isolated.

[0025] It also includes an anti-slip mechanism 3. The top surface of the upper cover 1 is recessed to form a circular groove 301 and an annular groove 302 for the anti-slip mechanism 3. The bottom wall of the base 2 is integrally formed with a raised foot 303 and an annular base 304 that cooperate with the anti-slip mechanism 3. The shape, size and position of the raised foot 303 are adapted to the circular groove 301, so that when the two lunch boxes are stacked, the circular groove 301 of the upper cover 1 of the lower lunch box can accommodate the raised foot 303 of the base 2 of the upper lunch box. The shape, size and position of the annular base 304 are adapted to the annular groove 302, so that the annular groove 302 of the upper cover 1 of the lower lunch box can nest and cooperate with the annular base 304 of the base 2 of the upper lunch box. Through the point positioning of the circular groove 301 and the raised foot 303 and the annular positioning of the annular groove 302 and the annular base 304, a double locking is formed, thereby improving the structural stability when the lunch boxes are stacked.

[0026] Meanwhile, a multi-functional anti-scalding mechanism 4 is also provided on the outer wall of the chassis 2. The multi-functional anti-scalding mechanism 4 includes a wave-shaped protrusion 401 integrally formed on the outer wall. The wave-shaped protrusion 401 forms an alternating texture structure on the outer wall of the chassis 2. When the user holds a lunch box containing hot food, the hand mainly contacts the protruding part of the wave-shaped protrusion 401, forming an air gap between the hand and the main wall of the chassis 2, effectively blocking heat conduction. At the same time, the physical texture of the wave-shaped protrusion 401 also increases the friction when the hand is holding it.

[0027] To facilitate the categorized storage of food, the interior of the chassis 2 is divided into a first inner cavity 403 and a second inner cavity 404. The first inner cavity 403 and the second inner cavity 404 are separated by an integrally formed partition wall within the chassis 2. The two cavities can be used to hold staple foods and dishes, or dry foods and wet foods, respectively, preventing cross-contamination of flavors or mixing between foods. In this embodiment, the first inner cavity 403 is a roughly rectangular cavity, while the second inner cavity 404 is a smaller arc-shaped or fan-shaped cavity to accommodate the needs of serving different portions of food.

[0028] To enhance the overall structural strength of the chassis 2, the first inner cavity 403 and the second inner cavity 404 are integrally reinforced by a connecting plate 6. The connecting plate 6 spans across the top of the partition wall separating the first inner cavity 403 and the second inner cavity 404, and the width of the connecting plate 6 is greater than the thickness of the partition wall. In this way, the connecting plate 6 acts like a reinforcing beam, which significantly improves the chassis 2's resistance to bending when loaded with heavy objects or subjected to stress, and prevents the chassis 2 from collapsing and deforming from the middle.

[0029] The annular groove 302 is concentrically surrounded by the circular groove 301. The circular groove 301 is located in the central area of ​​the top surface of the upper cover 1, while the annular groove 302 is surrounded by the same circle around the outside of the circular groove 301, forming a standard concentric circle structure. This layout ensures the accuracy and stability of positioning when stacking. The annular base 304 at the bottom of the chassis 2 is also concentrically surrounded by the raised foot 303. The raised foot 303 and the annular base 304 form a concentric raised shape that perfectly matches the groove structure of the upper cover 1, ensuring that the upper and lower food boxes can be smoothly aligned and nested when stacked.

[0030] To prevent liquid food from splashing out during movement, the multi-functional anti-scalding mechanism 4 also includes an inner convex ring 402. The inner convex ring 402 is a continuous ring ridge integrally formed on the upper edge of the opening of the base 2 and extending toward the inside of the first inner cavity 403 and the second inner cavity 404. This inner convex ring 402 forms a low wall at the opening of the food container. When the food container shakes and the soup inside the cavity is thrown toward the edge, the inner convex ring 402 can play a blocking and buffering role, effectively preventing liquid from overflowing.

[0031] The edge of the top cover 1 extends integrally to form a protruding corner 5. This protruding corner 5 is usually located at one corner of the top cover 1, and its outline slightly exceeds the outline of the base 2, providing a point of force and a lever point for the user's fingers to open. The user can easily release the detachable engagement between the top cover 1 and the base 2 by prying the protruding corner 5, and conveniently open the lunch box.

[0032] To provide uniform anti-slip and heat insulation effects throughout the entire gripping area, wavy protrusions 401 are distributed in a circumferential array on the outer walls of the first inner cavity 403 and the second inner cavity 404. This means that the outer sidewall surfaces of the first inner cavity 403 and the second inner cavity 404 are completely covered by this wavy structure, ensuring that the user's hand can contact the wavy protrusions 401 when picking up the lunchbox from any angle, thereby obtaining a reliable anti-slip and anti-scalding experience.

[0033] Working principle: When multiple lunch boxes need to be stacked for storage or transportation, the base 2 of one lunch box is placed on the top cover 1 of another lunch box. At this time, the raised foot 303 at the bottom of the upper lunch box base 2 will accurately fall into and engage with the circular groove 301 on the top surface of the lower lunch box top cover 1, forming the first positioning. At the same time, the annular base 304 of the upper lunch box base 2 will nest in the annular groove 302 of the lower lunch box top cover 1, completing the second ring fixation. Through the double nesting and engagement between the raised foot 303 and the circular groove 301, and between the annular base 304 and the annular groove 302, the lunch boxes are accurately positioned in the vertical stacking direction and effectively locked in the horizontal direction, thereby significantly enhancing the stability of the stack and preventing the occurrence of sliding and misalignment.

[0034] When a user needs to pick up a lunchbox containing hot food, their hand will come into contact with and grip the multi-functional anti-scalding mechanism 4 on the outer wall of the base 2. Specifically, the fingers mainly come into contact with the crest of the wave-shaped protrusion 401, naturally forming an air gap between the finger skin and the large area of ​​the base 2 wall. These air gaps act as an insulation layer, significantly reducing the heat conducted from the base 2 wall to the hand, thus achieving an anti-scalding effect. In addition, the physical texture formed by the wave-shaped protrusion 401 increases the friction when gripping, providing a reliable anti-slip effect, so that even if the user's hands or the surface of the lunchbox are contaminated with oil or moisture, they can still grip it stably.

[0035] In daily use, the protruding corner 5 formed by the integral extension of the edge of the top cover 1 provides users with a convenient point of leverage for opening. Users can easily lift the top cover 1. The inner protruding ring 402 on the upper edge of the opening of the base 2 can effectively prevent the internal liquid from splashing out when the lunch box is shaken. The connecting plate 6 set between the first inner cavity 403 and the second inner cavity 404 plays a reinforcing role in the overall structure of the base 2, improving the load-bearing capacity and durability of the lunch box.
