Abstract
Description
Technical Field
[0001] This invention relates to the field of aviation injection molded dinner plate technology, specifically to an anti-slip and spill-proof aviation injection molded dinner plate. Background Technology
[0002] Aviation injection-molded trays are disposable tableware made from food-grade plastics (such as polystyrene PS or polypropylene PP), injection molded at 260℃, and then sterilized with ultraviolet light and aseptically packaged. Their characteristics include lightweight, high transparency, and compliance with aviation safety standards; they are commonly used in in-flight services.
[0003] Most existing airline meal trays are flat or shallow-grooved designs, which have the following drawbacks:
[0004] 1. Insufficient anti-slip performance: The friction between the plate and the smooth plastic tabletop is small, making it easy to slip when bumpy, resulting in food spillage.
[0005] 2. Poor spill prevention: The shallow design of the tray has limited capacity to hold liquids such as vegetable juices. When the liquid is shaken, it is very easy for it to overflow from the tray or the edge of the plate, staining the table and passengers' clothes.
[0006] Therefore, there is an urgent need for a non-slip and spill-proof aviation injection molded dinner plate to solve the problems of easy leakage and slipperiness of aviation injection molded dinner plates. Summary of the Invention
[0007] To address the shortcomings of existing technologies, this invention provides a non-slip and spill-proof aviation injection molded dinner plate, which has the advantage of preventing food juice from spilling and solves the problems of easy leakage and slipperiness of aviation injection molded dinner plates.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a non-slip and spill-proof aviation injection molded dinner plate, comprising a dinner plate body and a partition disposed inside the dinner plate body, the dinner plate body and the partition forming two secondary dinner slots and one main dinner slot, the secondary dinner slots being provided with a guide channel, and a pressure plate being rotatably connected to the slot at the top of the outer wall of the dinner plate body via a connecting rod, the pressure plate being pressed against the top of the secondary dinner slots.
[0009] Preferably, several groups of the guide channels are evenly distributed inside the side dish dish; the guide channels are multiple parallel shallow channels that can effectively guide and contain the vegetable juice, prevent the liquid from flowing over a large area at the bottom of the dish, thereby reducing the risk of spillage due to shaking.
[0010] Preferably, the bottom of the plate body is provided with a washer, an anti-slip sheet one, and an anti-slip sheet two. The washer is located at the four corners of the bottom of the plate body. The anti-slip sheet one is placed at an angle. The bottom of the anti-slip sheet two is provided with anti-slip texture. The anti-slip sheet one and the anti-slip sheet two are made of silicone or thermoplastic elastomer and are firmly bonded to the plate body through an insert injection molding process.
[0011] Preferably, a protective ring is provided at the bottom edge of the plate body. The protective ring is made of rubber material, which can effectively improve the impact resistance of the plate body.
[0012] Preferably, the anti-slip sheets on both sides of the second anti-slip sheet are symmetrically distributed.
[0013] In summary, the present invention has at least one of the following beneficial effects:
[0014] 1. This anti-slip and spill-proof aviation injection-molded dinner plate features a guide channel within the secondary serving compartment that guides and accommodates small amounts of spilled liquid, effectively enhancing the plate's spill-proof capability. Simultaneously, the rotatable pressure plate design secures lightweight food items within the secondary serving compartment, preventing them from popping out during turbulence, thus improving the cleanliness and convenience of dining. Furthermore, the pressure plate, located at the top of the secondary serving compartment, shields any spilled food, further enhancing the spill-proof performance of the aviation injection-molded dinner plate.
[0015] 2. This anti-slip and spill-proof aviation injection molded dinner plate, through the bottom gasket, symmetrically inclined anti-slip plate one, and anti-slip plate two with anti-slip texture, forms a multi-layered, multi-directional anti-slip system, which significantly increases the friction between the dinner plate and the tabletop and effectively prevents the dinner plate from sliding; the protective ring design on the bottom edge further enhances the stability and safety of the dinner plate, providing dual protection against slipping and wear.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figure 1-4 A non-slip and spill-proof aviation injection molded dinner plate includes a dinner plate body 1, a partition 2 disposed inside the dinner plate body 1, two secondary dinner slots and a main dinner slot formed by the dinner plate body 1 and the partition 2, a guide channel 3 disposed inside the secondary dinner slot, and a pressure plate 4 rotatably connected to the slot at the top of the outer wall of the dinner plate body 1 via a connecting rod, the pressure plate 4 pressing against the top of the secondary dinner slot, and several sets of guide channels 3 are evenly distributed inside the secondary dinner slot.
[0023] Through the above technical solution, the plate body 1 is functionally divided by the partition 2. The main serving dish is used to hold staple food, and the two secondary serving dishes can be held separately. When the food juice in the secondary serving dishes is shaken, the evenly distributed guide channels 3 can guide and disperse the food juice, preventing the food juice from pooling at the bottom of the dish, thus making it less likely for the food juice to spill out when the dish is shaken.
[0024] The press 4 is made of transparent polypropylene and is connected to the plate body 1 via a connecting rod, allowing it to rotate 180 degrees.
[0025] When not in use, it can be rotated to the outside of the plate without affecting the taking and putting away of food;
[0026] When in use, the pressing plate 4 is pressed tightly into the secondary food tray inside the plate body 1 to protect the plate body 1 and prevent food juice from spilling out.
[0027] Specifically, the bottom of the plate body 1 is provided with a washer 5, an anti-slip sheet 1 6 and an anti-slip sheet 2 7. The washer 5 is located at the four corners of the bottom of the plate body 1. The anti-slip sheet 1 6 is placed at an angle. The bottom of the anti-slip sheet 2 7 is provided with anti-slip texture. The anti-slip sheets 1 6 located on both sides of the anti-slip sheet 2 7 are symmetrically distributed.
[0028] The above technical solution, through the bottom gasket 5, the symmetrically inclined anti-slip sheet 6 and the anti-slip sheet 7 with anti-slip texture, constitutes a multi-layered, multi-directional anti-slip system, which significantly increases the friction between the plate and the tabletop and effectively prevents the plate from sliding.
[0029] Specifically, a protective ring 8 is provided at the bottom edge of the plate body 1.
[0030] The above technical solution, through the design of the protective ring 8 on the bottom edge, further enhances the stability and safety of the plate, and plays a dual role in preventing slipping and wear.
[0031] When in use, after distributing the meal, the flight attendant can press the pressure plate 4 firmly onto the top of the secondary serving tray. When the tray is placed on the passenger tray table, the bottom gasket 5, anti-slip pad 1 6, anti-slip pad 2 7, and protective ring 8 work together to ensure the tray remains stable during flight turbulence. The guide channel 3 inside the secondary serving tray guides the movement of food juices, preventing spillage and providing passengers with a safe and clean dining experience.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
