[0002] Currently used traditional paper bowls have significant shortcomings in sealing performance. Most of them use ordinary buckles or simple film designs. Buckles are prone to loosening due to bumps, and film is prone to wrinkles and damage, leading to sealing failure. Liquid foods such as soup and sauces are very easy to leak, which not only contaminates the packaging and clothing, but also affects the taste and hygiene of the food. Moreover, traditional bowls lack professional anti-leakage structures. Even if the initial sealing is acceptable, the risk of leakage increases significantly when delivered over a long period of time or placed at an angle, resulting in a very poor user experience.

[0003] The wedge-shaped edge and wedge-shaped groove sealing structure of this utility model's PHA coated paper bowl can fit tightly to form a strong seal, effectively preventing liquid leakage. At the same time, the disposable easy-tear design ensures that the food is not opened or contaminated during delivery, while also allowing users to quickly verify the integrity of the food upon receipt. This solves the problem of leakage prevention in traditional bowls and improves the safety and convenience of takeout meals. Utility Model Content

[0019] 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.

[0020] To achieve the above-mentioned utility model objectives, such as Figure 1-11 As shown, this utility model provides a PHA-coated paper bowl with enhanced sealing and leak-proof properties. Before installing each mechanism, a basic inspection of the bowl body 1 must be performed. First, confirm that the PHA coating layer used on the bowl body 1 is evenly covered without damage, bubbles, or missed coating. This is the basis for ensuring the overall leak-proof performance. Next, check the wedge-shaped groove 4 on the outer side of the upper end of the bowl body 1 to ensure that the groove structure is intact, the edges are free of burrs, and the easy-tear structure on the outer side of the wedge-shaped groove 4 is intact, with the easy-tear opening 20 clearly identifiable, without breakage or deformation. At the same time, check the spare bowl bottom 12 at the bottom of the bowl body 1 to confirm that it is firmly connected to the main bowl bottom and can be used normally in case of accidental damage to the main bowl bottom, providing a foundation for the subsequent mechanism installation.

[0021] Sealing Mechanism: First, install the bowl lid 2. Take the main body of the bowl lid 2 and install the handle base 5 at the center of its upper end. Use a special food-grade adhesive to fix the handle base 5 to the bowl lid 2, ensuring that the joint surfaces are tightly fitted without gaps. Let it stand for a period of time to allow the adhesive to fully cure, ensuring that the handle base 5 is firmly installed. After the handle base 5 has cured, install the lifting ring 6 onto the handle base 5 for easy lifting by the user. Then, install four reinforcing ribs 3 on the upper circumference of the bowl lid 2. The reinforcing ribs 3 are made of the same PHA material as the bowl lid 2. Use adhesive to fix one end of each of the four reinforcing ribs 3. The four reinforcing ribs 3 are fixed on the circumference of the bowl lid 2, and the other end is connected to the handle base 5. During installation, it is necessary to ensure that the four reinforcing ribs 3 are evenly distributed on the upper part of the bowl lid 2 and there is no gap between them and the connection surface of the bowl lid 2 and the handle base 5, so as to enhance the overall structural strength of the bowl lid 2 and prevent the bowl lid 2 from deforming during use. Finally, two fixing blocks 15 are installed at the middle position of the lower end of the bowl lid 2. The fixing blocks 15 are also fixed to the bowl lid 2 with adhesive. The distance between the two fixing blocks 15 should match the length of the spoon 16 to ensure that the spoon 16 can be placed stably between the two fixing blocks 15 and will not easily shake or fall off.

[0022] The material of the wedge edge 17 must match that of the wedge groove 4 to ensure good sealing and compatibility. The upper end of the wedge edge 17 is fixedly connected to the lower edge of the bowl lid 2 using food-grade adhesive. During the connection process, it is necessary to ensure that the wedge edge 17 is aligned with the edge of the bowl lid 2 without any misalignment, and that the connection surfaces are tight. After the adhesive has cured, align the wedge edge 17 at the lower end of the bowl lid 2 with the wedge groove 4 on the outer side of the upper end of the bowl body 1, and slowly insert the wedge edge 17 into the wedge groove 4. During the insertion process, even force must be applied to ensure that the wedge edge 17 is fully embedded in the wedge groove 4 without any loosening. At this point, the bowl body 1 and the bowl lid 2 are sealed together through the wedge edge 17 and the wedge groove 4.

[0023] Separating Mechanism: Take the first baffle 10 and the second baffle 11 respectively. Both are made of paper material with PHA coating, ensuring that their surfaces are flat and free from bending or damage. Inspect the first slot 13 on the upper side of the middle position of the first baffle 10 and the second slot 14 on the upper side of the middle position of the second baffle 11 to confirm that the size and shape of the slots are consistent, the edges are free of burrs, and they can be properly engaged. Place the first baffle 10 horizontally into the bowl 1, adjust the position of the first baffle 10 so that its two ends are tightly fitted to the inner wall of the bowl 1, and maintain... With the bowl horizontal, place the second baffle 11 vertically inside the bowl 1, aligning the second slot 14 in the middle of the second baffle 11 with the first slot 13 in the middle of the first baffle 10. Slowly press the second baffle 11 downwards to engage the first slot 13 and the second slot 14. During the engagement process, ensure that the two baffles are fully engaged without any looseness. At this point, the first baffle 10 and the second baffle 11 divide the internal space of the bowl 1 into four independent areas, which can be used to hold different types of food separately, preventing the food from mixing or having different flavors.

[0024] Exhaust mechanism: At the exhaust port 18 pre-opened on the upper right side of the bowl lid 2, an exhaust pipe 7 is installed. The exhaust pipe 7 is made of food-grade plastic and its lower end matches the size of the exhaust port 18. The lower end of the exhaust pipe 7 is fixed to the exhaust port 18 with adhesive to ensure that the exhaust pipe 7 is perpendicular to the bowl lid 2 and that there are no gaps at the connection surface to prevent gas from leaking from the connection part.

[0025] The threaded column 9 is made of food-grade plastic. Six connecting rods 19 are evenly distributed around its lower circumference. The connecting rods 19 are made of the same material as the threaded column 9 and are fixedly connected to the threaded column 9 through an integrated molding process, ensuring that the connecting rods 19 are perpendicular to the threaded column 9 and that the connection is firm. Then, the assembled threaded column 9 and connecting rods 19 are placed inside the exhaust pipe 7. The position is adjusted so that the threaded column 9 is located at the center inside the exhaust pipe 7. Then, the ends of the six connecting rods 19 away from the threaded column 9 are fixedly connected to the inner wall of the exhaust pipe 7 with adhesive. During the installation process, it is necessary to ensure that the threaded column 9 remains stable inside the exhaust pipe 7 without shaking.

[0026] A limiting plate is installed at the upper end of the threaded column 9. The limiting plate is fixed to the threaded column 9 by an integral molding method. The diameter of the limiting plate is larger than the diameter of the threaded column 9. It is used to limit the rising position of the exhaust cover 8 and prevent the exhaust cover 8 from falling off the threaded column 9. Finally, the exhaust cover 8 is threaded to the middle of the threaded column 9 through the internal threads. The exhaust cover 8 is located outside the exhaust pipe 7, and the size of the exhaust cover 8 is larger than the size of the exhaust pipe 7 to ensure that the exhaust cover 8 can completely cover the upper opening of the exhaust pipe 7 to achieve a sealing effect.

[0027] The working process of the PHA coated paper bowl with enhanced sealing and leak-proof properties provided by this utility model is as follows: Based on the type of food to be contained, four independent areas are created using a separating mechanism. Different foods are placed into their respective areas. After the food is placed, check that the spoons 16 between the fixing blocks 15 at the lower end of the bowl lid 2 are properly positioned for easy use. Align the wedge-shaped edge 17 at the lower end of the bowl lid 2 with the wedge-shaped groove 4 of the bowl body 1, and then press the edge of the bowl lid 2 evenly by hand to engage the wedge-shaped edge 17 with the wedge-shaped groove 4, enhancing the sealing effect and preventing leakage during transport or storage. After sealing, the user can lift the paper bowl using the lifting ring 6 on the bowl lid 2. The four reinforcing ribs 3 effectively prevent the bowl lid 2 from deforming due to force during lifting. When storing, the paper bowl can be placed stably in a suitable position. Due to its excellent sealing performance, the food can remain fresh for a certain period of time and will not contaminate other items due to leakage. When the food needs to be taken out, the user can first tear open the easy-tear structure on the outer side of the wedge-shaped groove 4 through the easy-tear opening 20, and then gently lift the bowl lid 2. If steam is generated inside the bowl, first follow the venting procedure to release the steam before opening the lid 2 to avoid sudden scalding of your hands. Then, remove the spoon 16 from between the fixed blocks 15 to take food from each area.

[0028] Preferred Features: This PHA coated paper bowl, with its disposable design, provides crucial protection for the safety of takeout meals. Regarding tamper-proofing and contamination prevention, the easy-tear structure on the outer side of the wedge-shaped groove 4 is a one-time design, with the easy-tear opening 20 being the only opening point. After the merchant seals the bowl body 1 and lid 2, the easy-tear structure forms a protective barrier. If the food needs to be opened during delivery, the easy-tear structure must be broken, and once broken, it cannot be restored, leaving a clear mark. This physically prevents tampering and contamination during transit, ensuring the food's safety and integrity. For verification upon opening, users can visually determine that the easy-tear structure is intact and the easy-tear opening 20 is not torn when unopened; if the structure is damaged, it can be directly determined that the food has been opened, facilitating timely rights protection for users, saving time and enhancing consumer trust.
