Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, specifically to an EPP insulated box for takeout. Background Technology

[0002] As a core piece of equipment in modern delivery services, insulated food delivery boxes effectively maintain the temperature of meals through heat-insulating materials and sealing designs. This not only ensures the food remains hot or chilled but also reduces energy consumption from multiple heating processes. It not only directly improves the dining experience and food safety for consumers but also helps merchants establish a professional and reliable brand image, promotes the standardization and efficiency of the food delivery industry, and becomes an important bridge connecting merchants and customers.

[0003] While insulated food delivery boxes provide a good transportation environment for takeout meals, they still have certain problems: 1) Existing insulated boxes cannot effectively separate hot and cold food, leading to cross-contamination of flavors and temperature interference; 2) Takeout items are prone to tipping, collisions, and spillage during transportation due to shaking and bumping; 3) The internal space utilization rate of the box is low, and it is inconvenient to retrieve and lower items; 4) The internal space partitioning adjustment mechanism is complex to operate, requires tools, and cannot achieve rapid stepless adjustment. Therefore, in view of the above situation, there is an urgent need to develop an EPP insulated food delivery box to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a takeaway EPP insulated box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a takeaway EPP insulated box, comprising a box body, the interior of which is provided with:

[0006] At least one guide component is fixed to the inner wall of the housing;

[0007] The partitioning component is slidably connected to the guide and can move to different positions inside the housing along the direction of the guide, thereby dividing the interior space of the housing into at least two sub-spaces; the partitioning component is provided with a first locking device for locking it at any position on the guide;

[0008] At least one restraining device is slidably connected to a guide member and can be positioned within any subspace separated by partition members to restrain the position of an item placed within that subspace.

[0009] The layered assembly is movably disposed inside the box. The layered assembly includes a horizontally movable shelf and a movable plate rotatably connected to the bottom edge of one side of the shelf. The movable plate has a first state in which it, together with the shelf, forms a complete layered plane to divide the internal space of the box into upper and lower sections, and a second state in which it is flipped upward relative to the shelf.

[0010] Specifically, the combination of sliding and locking partition components and guide components enables flexible division of the internal space of the box, effectively avoiding cross-contamination between hot and cold foods; the positioning constraint device and its elastic constraint components stabilize the items inside the box, preventing spillage during transportation; and the layered components consisting of horizontally movable shelves and flip-up movable panels enable convenient expansion of the upper space and unobstructed access to the lower space, greatly improving space utilization and ease of use.

[0011] Preferably, the constraint device includes a frame connected to the guide member and an elastic constraint member disposed on the frame. The frame includes a slider, a connecting rod, a sliding sleeve, and a second locking device. The slider and the sliding sleeve are respectively sleeved on the guide member. The connecting rod is vertically fixed between the slider and the sliding sleeve. A groove is provided on the slider. The second locking device is disposed in the groove for locking the slider and the guide member.

[0012] Specifically, the sliding engagement of the sliding parts and the sliding sleeve on the horizontally installed guide allows for flexible and smooth adjustment of the overall horizontal position of the frame; its second locking device can quickly lock it in any desired position in the horizontal direction, thus stably adapting to and restraining the items; the elastic restraint can closely fit the outer surface of the items, effectively preventing shaking, collision and spillage during transportation, while avoiding damage to the packaging of the items that may be caused by rigid contact.

[0013] Preferably, the first locking device and the second locking device are quick-locking structures based on the principle of eccentric cam and friction block.

[0014] Specifically, by employing a first locking device and a second locking device based on the principle of eccentric cams or friction blocks, the rapid locking and releasing of the partition components and constraint devices are achieved. Users only need to press or pull the lever once by hand to complete the locking, without any tools, making the operation extremely convenient and efficient. Utilizing the wedge-tightening effect of the cam or the self-locking effect of the friction block, it can provide stable and reliable locking force at different positions of the guide component, preventing loosening during transportation. At the same time, this stepless adjustment structure can adapt to locking at any position, greatly improving the flexibility of space partitioning and fixing of the insulated box and enhancing the user experience.

[0015] Preferably, a boss is fixed on the inner wall of the box, and the layered components are slidably mounted on the boss.

[0016] Preferably, the shelf is provided with a limiting structure for accommodating cup-shaped objects, the upper surface of the movable plate is provided with a first magnetic attractor, and the outer wall of the limiting structure is provided with a second magnetic attractor. When the movable plate is in the second state, the first magnetic attractor and the second magnetic attractor are magnetically connected.

[0017] Specifically, by setting a first magnetic attraction component on the movable plate and a corresponding second magnetic attraction component on the outer wall of the shelf's limiting structure, the two components can automatically attract and remain stable through magnetic force when the movable plate is flipped up to the second state. This achieves quick, reliable, and manual fixation of the movable plate in the flipped-up state, eliminating the need for additional mechanical latches and greatly facilitating users in taking down items from the lower shelf. At the same time, the limiting structure on the shelf effectively secures cup-shaped containers, preventing them from tipping over during transportation. The combination of magnetic attraction and limiting structure significantly improves the ease of operation and the practicality of space utilization.

[0018] Preferably, the elastic constraint is an elastic mesh, elastic cloth, or elastic band.

[0019] Specifically, it has good elasticity and adaptability, and can closely fit the outer surface of items of different sizes and shapes, providing flexible lateral restraint force to effectively prevent items from shaking, colliding and spilling during transportation; at the same time, its elasticity avoids rigid contact, which can better protect the packaging of items from damage, and has a wider range of applications.

[0020] Preferably, the box is made of EPP foam material.

[0021] Preferably, the guide members are parallel sliding rods or sliding shafts, and there are a total of four guide members.

[0022] Preferably, bushings for sliding connection with guide members are provided at the four corners of the partition component, and a groove communicating with the inside of the bushing is opened at the top edge of the partition component. A first locking device is provided in the groove for locking the partition component and the guide member. The partition component can be a heat insulation board.

[0023] Specifically, by setting bushings at the four corners of the partition components, the sliding connection between them and the guide components is made smoother and more stable, reducing friction and wear; the first locking device is integrated into the groove on the top edge, forming a concealed and ergonomic operating interface, which allows users to quickly lock and unlock by hand, making operation convenient and less prone to accidental contact; the partition components are made of heat-insulating panels, which can effectively block heat transfer between the two sub-spaces, significantly improving the heat preservation effect of hot and cold partition storage in the box, avoiding temperature cross-contamination, and ensuring the best taste of food.

[0024] Compared with the prior art, this utility model provides a takeaway EPP insulated box, which has the following beneficial effects:

[0025] The box's interior space is flexibly divided by sliding, lockable, insulated partitions, effectively isolating hot and cold foods from temperature interference and ensuring optimal taste. A horizontally adjustable elastic restraint device tightly fits and secures takeout items of different sizes, preventing collisions and spills during transport. An innovative sliding, flip-up layered structure allows for convenient expansion of the upper space and unobstructed access to the lower space, greatly improving space utilization and ease of operation. The overall structure features stepless adjustment and quick-locking design, allowing for easy adaptation to various delivery needs without tools, combining functionality, practicality, and user experience.
