Description

Technical Field

[0001] This utility model belongs to the technical field of catering packaging, specifically relating to a partitioned paper plate that can accommodate different types of food. Background Technology

[0002] Divided paper plates that can accommodate different types of meals are a common product in the catering packaging industry. They are rectangular paper plates with clearly defined compartments for main dishes, side dishes, and other dishes, allowing for the categorization and storage of different meals and preventing flavor mixing. They are also equipped with edge-protecting paper frames to reduce spillage. They are widely used in takeout delivery, work meals, fast food chains, and other scenarios, meeting people's needs for convenient and hygienic food storage. However, existing partitioned paper trays have problems in meeting diverse needs in terms of structural stability, heat preservation, and environmental economy. On the one hand, the main body of the paper tray is made of paper, which has weak resistance to deformation. When holding heavy food (such as main dishes with soup) or when the force is uneven when picking it up, the paper tray is prone to edge curling and bottom denting, which not only affects the appearance but may also cause the food to tip over. If the paper is thickened to increase strength, it will increase costs and resource consumption, and cannot fundamentally solve the deformation problem. On the other hand, paper conducts heat quickly and has no heat preservation function. For food that needs to be delivered or stored for a long time, heat is easily lost quickly, causing the food temperature to drop and affecting the taste. Utility Model Content

[0003] The purpose of this invention is to provide a partitioned paper plate that is suitable for different types of food, in order to solve the problems mentioned in the background art. The existing partitioned paper plates are made of paper, which has weak resistance to deformation. When holding heavy food (such as main dishes with soup) or when the force applied is uneven, the edges are prone to curling and the bottom is concave, which not only affects the appearance but may also cause the food to spill. Although thickening the paper can increase the strength, it will increase the cost and resource consumption.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a partitioned paper plate suitable for different meals, comprising a rectangular paper plate body and a paper frame disposed at the bottom edge of the rectangular paper plate body, the paper frame being flush with the outer wall of the rectangular paper plate body edge; the rectangular paper plate body having multiple partitioned placement slots inside, the main body of each partitioned placement slot protruding downwards on the rectangular paper plate body, and the openings of each partitioned placement slot facing upwards; the center of each of the left and right ends of the paper frame having paper plate end slots, the U-shaped openings of the two paper plate end slots facing downwards; and the bottom and exterior of the rectangular paper plate body and the paper frame being equipped with a reusable anti-deformation and heat-insulating device.

[0005] Preferably, the reusable anti-deformation and heat preservation device includes a plastic anti-deformation base plate and a plastic anti-deformation frame. The plastic anti-deformation frame is sleeved around the outside of the paper frame. The plastic anti-deformation frame is integrally formed with the plastic anti-deformation base plate, and the bottom of the paper frame is placed directly on the plastic anti-deformation base plate.

[0006] Preferably, the reusable anti-deformation and heat preservation device further includes an insulation board and a placement slot connecting groove. The top of the plastic anti-deformation base plate is provided with an insulation board, and the paper frame is inserted into the area between the plastic anti-deformation frame and the insulation board. The insulation board has multiple downwardly recessed placement slot connecting grooves with upward openings inside.

[0007] Preferably, the reusable anti-deformation and heat preservation device further includes a reserved opening for the end slot. The left and right ends of the plastic anti-deformation frame are both provided with reserved openings for the end slot. The U-shaped openings of the two reserved openings for the end slot face upwards, and the two reserved openings for the end slot overlap on the outside of the two paper tray end slots.

[0008] Preferably, the multiple placement slots inside the insulation board correspond one-to-one with the shape, size and position of the multiple partition placement slots, and the multiple placement slots are respectively fitted onto the outside of the downward protruding body of the multiple partition placement slots.

[0009] Preferably, the plastic anti-deformation base plate and plastic anti-deformation frame are made of food-grade polypropylene, and the insulation board is made of extruded polystyrene foam. The plastic anti-deformation base plate, plastic anti-deformation frame, and insulation board can all be washed repeatedly.

[0010] Preferably, the plurality of partitioned placement slots are respectively a staple food placement slot, a side dish placement slot, a side dish and dipping sauce placement slot, a main dish placement slot, and a tableware placement slot. The tableware placement slot is located inside the rectangular paper plate body near the right end. The side dish and dipping sauce placement slot is located inside the rectangular paper plate body near the left rear corner. The staple food placement slot and the side dish placement slot are located inside the middle section of the rectangular paper plate body, and the staple food placement slot is located in front of the side dish placement slot.

[0011] Preferably, an anti-overflow paper frame is provided at the outer edge of the top of the rectangular paper tray body, and the anti-overflow paper frame protrudes upward to prevent liquid from overflowing.

[0012] Compared with the prior art, this utility model provides a partitioned paper plate that can adapt to different meals, and has the following beneficial effects: This invention adds a novel reusable anti-deformation and heat-insulating device to the bottom and outside of a partitioned paper plate adapted for different meals. This device provides solid structural support for the paper plate and gives it heat-insulating function, effectively preventing the paper plate from deforming during use. At the same time, it realizes the reusability of the device, taking into account practicality, economy and environmental protection requirements. The plastic anti-deformation base plate and plastic anti-deformation frame of the reusable anti-deformation and heat-insulating device are integrally molded from high-strength polypropylene to form a stable tray-like support structure. When the partitioned paper plate is placed on it, the base plate provides full support from below, and the frame wraps around the paper plate from all sides, jointly resisting the weight of the food, external pressure, and torque generated when the hand picks it up. This all-round support design can effectively prevent the paper plate from warping, denting or bending due to carrying hot food, soup or stacking, ensuring that the plate maintains structural integrity and aesthetics throughout the entire use process. The reusable anti-deformation insulation device uses a built-in extruded polystyrene foam material for its insulation board. Its closed-cell structure provides excellent heat insulation performance. The insulation board is precisely embedded in the bottom of the paper tray and is fitted tightly with the various compartments of the paper tray through the placement slots. This ensures that the heat at the bottom of the paper tray can be more effectively transferred to the insulation board and locked in for heat preservation. At the same time, the insulation board blocks the main path of rapid heat conduction from the bottom of the paper tray to the outside air, slowing down heat convection and heat conduction. In this way, the reusable anti-deformation insulation device can significantly slow down the rate at which the food temperature drops, giving users more time to eat. This is especially beneficial for scenarios that require delivery or are inconvenient to eat immediately, effectively improving the dining experience. Furthermore, the core components of this reusable, anti-deformation, and heat-insulating device (plastic base plate, frame, and insulation board) are all made of durable and washable materials. The anti-deformation structure made of polypropylene and the insulation board made of extruded polystyrene foam have good chemical resistance and anti-aging properties, and can withstand multiple washes and wipes without damage or loss of function. This allows the device to be used with disposable paper plates. After a meal, simply discard the used paper plates and perform a simple cleaning and disinfection of the device before reuse.

Detailed Implementation

[0018] 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.

[0019] This utility model provides, for example Figure 1-4 The illustration shows a partitioned paper plate adapted to different types of food. This partitioned paper plate is designed with partitioned storage, spill protection, and circulating insulation support as its core features. Through precise structural layout and material matching, it achieves classified storage, leak protection, and reusability of food. The rectangular paper plate body 1 is the core load-bearing component of the entire paper plate. A paper frame 4 is integrally formed at the bottom edge of the rectangular paper plate body 1, and the paper frame 4 is flush with the outer wall of the edge of the rectangular paper plate body 1. The principle of this flush design is to ensure the overall appearance of the paper plate is neat, and at the same time, to provide a suitable base for the subsequent fitting of the reusable anti-deformation insulation device 2. This avoids the device not being able to fit tightly due to the paper frame 4 protruding or shrinking. The function of the paper frame 4 is to enhance the structural strength of the edge of the rectangular paper plate body 1, prevent the edge of the paper plate from curling due to force (such as picking up or stacking), and at the same time provide a positioning reference for the assembly of the rectangular paper plate body 1 and the reusable anti-deformation insulation device 2.

[0020] like Figure 1 and Figure 2As shown, U-shaped downward-facing tray placement slots 10 are provided inside the center of both ends of the paper tray frame 4. The design principle is to provide a convenient point of leverage for the user to pick up the tray. The user's fingers can be inserted into the slots to grip both ends of the paper tray frame 4, achieving stable tray handling and preventing direct contact with the tray body from spilling food. Simultaneously, the downward-facing openings prevent the accumulation of soup or broth in the slots, keeping the handling area clean and improving ease of use. At the top outer edge of the rectangular tray body 1, an upward-protruding anti-overflow tray 7 is provided. Its function is to physically prevent liquids (such as soup or sauce) inside the tray from spilling out. When the plate tilts slightly or liquids shake due to food placement, the spill-proof paper frame 7 forms a protective barrier, confining the liquid inside the paper plate to prevent contamination of hands or tabletops. It is especially suitable for storing dishes containing broth (such as stir-fries and soups), enhancing the practicality of the paper plate. The rectangular paper plate body 1 has multiple clearly defined compartments inside. The main body of each compartment protrudes downwards on the rectangular paper plate body 1, with the opening facing upwards. The principle of the downward protrusion structure is to increase the depth of the compartment, thereby increasing the food storage capacity, while preventing food from different compartments from mixing. The upward-facing opening makes it easy for users to directly put or take food in and out, which conforms to daily dining habits.

[0021] like Figure 1 and Figure 2 As shown, both the main dish placement slot 3 and the side dish placement slot 5 are located inside the middle section of the rectangular paper plate body 1, with the main dish placement slot 3 positioned in front of the side dish placement slot 5. The principle behind this centrally located layout is that the middle area is the most convenient place for users to take their food. Placing the main dish (such as rice or noodles) and side dishes (such as stir-fried vegetables or cold dishes) here aligns with the common dining order of taking the main dish first and then the side dish. The front-to-back arrangement prevents interference between the two types of food when taking them, and the spacing between the slots prevents the sauces from mixing, ensuring that their flavors don't blend. The main dish placement slot 8, as the core of the meal, is typically larger than the other slots. Its placement is adjacent to the main dish placement slot 3 and the side dish placement slot 5, designed to facilitate the user placing the main dish... When eaten with main dishes and side dishes, the hand movement range during food retrieval is reduced, improving dining efficiency. The side dish and dipping sauce placement slot 6 is located inside the rectangular paper plate body 1 near the left rear corner. This position is relatively independent because side dishes (such as pickled vegetables and appetizers) or dipping sauces (such as soy sauce and vinegar) are used in small quantities and do not need to be retrieved frequently. The independent layout can prevent them from being mixed with main and side dishes, and at the same time, it does not occupy the core food retrieval area, taking into account practicality and space utilization. The utensil placement slot 9 is located inside the rectangular paper plate body 1 near the right end. Its principle is to store utensil (such as disposable chopsticks and spoons) separately from food, avoiding utensil contamination of food. At the same time, the right end position is adapted to the user's eating habits (most people are right-handed, and there is no need to cross the food area when retrieving utensil), improving the convenience of use.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the core supporting components of the reusable anti-deformation insulation device 2 are the plastic anti-deformation base plate 12 and the plastic anti-deformation frame 13. Both are integrally molded from food-grade polypropylene. The advantages of food-grade polypropylene are: firstly, its high rigidity, which provides stable support and prevents the paper tray from deforming; secondly, its good temperature resistance (withstanding -20℃ to 120℃), suitable for storing hot and cold food; and thirdly, both can be repeatedly washed without performance degradation after washing. The plastic anti-deformation frame 13 is fitted around the outside of the paper frame 4, and the plastic anti-deformation base plate... The 12th part is located at the bottom of the paper frame 4, which is placed directly on the plastic anti-deformation base plate 12. The principle of this structure, which is connected around the four sides and supported at the bottom, is to provide comprehensive support for the paper plate in three dimensions. The plastic anti-deformation frame 13 can resist the lateral pressure on the edge of the paper plate (such as the squeezing when picking it up) and prevent the edge from deforming. The plastic anti-deformation base plate 12 can distribute the weight of the food on the bottom of the paper plate and prevent the paper plate from denting due to excessive local stress (such as the concentrated weight of the main dish), ensuring that the paper plate remains flat during use.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, an extruded polystyrene foam insulation board 14 is fixedly installed on the top of the plastic anti-deformation base plate 12. The insulation principle of extruded polystyrene foam is that its internal closed-cell structure can block heat conduction and heat convection. The air in the closed cells cannot flow freely, reducing the loss of heat through air transfer. At the same time, the thermal conductivity of the foam itself is extremely low (approximately 0.03 W / (m²)). K) can effectively delay the loss of heat from food, especially suitable for meals that need to be stored for a long time (such as takeout and work meals). The insulation board 14 has multiple downward-recessed, upward-opening placement slots 15. The shape, size and position of each placement slot 15 correspond one-to-one with the placement slots of each partition. They are respectively fitted onto the downward-protruding parts of the partition placement slots. The principle of this one-to-one fitting is that it can first increase the contact area between the insulation board 14 and the partition placement slots, allowing the insulation board 14 to more fully wrap the slots and improve the insulation efficiency. Secondly, the fitting can achieve precise positioning of the paper tray and the insulation board 14, preventing the paper tray from shifting in the insulation device and ensuring that each slot and the insulation structure are always aligned. In addition, its recessed fitting slots can provide additional support for the partition placement slots, further enhancing the deformation resistance of the slots.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, U-shaped openings 11 are provided inside the center of both ends of the plastic anti-deformation frame 13, with the openings facing upwards. The two openings overlap on the outside of the two paper tray end slots 10. The principle is to ensure that the paper tray end slots are not blocked by the insulation device. Users can still take the paper tray through the original paper tray end slots 10, and their operating habits are not affected. At the same time, the size of the openings is slightly larger than the paper tray end slots 10 to avoid friction between the two and damage to the paper tray. In addition, the plastic anti-deformation base plate 12, the plastic anti-deformation frame 13 and the insulation board 14 can be washed repeatedly. The principle is that the selected materials (food-grade polypropylene and extruded polystyrene foam) have good water resistance. During washing, water will not penetrate into the material and cause structural damage or a decrease in insulation performance. After washing, it can be reused after drying. This achieves one-time investment and multiple reuse, which reduces the cost of use and the generation of disposable waste, meeting environmental protection requirements.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
