Technical Field

[0001] This utility model belongs to the field of paper bowl technology, and specifically relates to a paper bowl that is resistant to deformation. Background Technology

[0002] Paper bowls are disposable tableware made of paper or cardboard, commonly used for holding food and beverages. They are typically manufactured through processes such as die-cutting, forming, pressing, and coating. To improve their water resistance and durability, the inside of paper bowls is often coated with a layer of polyethylene (PE) or other types of waterproof coating. Due to their lightweight, low cost, and ease of recycling, paper bowls are widely used in the fast food and takeout industries.

[0003] Existing paper bowls are prone to deformation when filled with high temperatures or excessive amounts of liquid, subjected to external pressure, improper stacking, or dampness. Deformed paper bowls may experience problems such as bottom dents and side wall collapse, leading to liquid leakage and affecting normal use. At the same time, deformation may also damage the waterproof coating inside the paper bowl, posing food safety hazards, reducing user experience, and even causing consumers to distrust product quality and brand, increasing the risk of after-sales complaints and waste. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a paper bowl that is resistant to deformation. By strengthening the paper bowl with ribs inside the bowl and enhancing the material of the bowl itself, the paper bowl can be effectively prevented from deforming, thus improving its practicality and user experience.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a deformation-resistant paper bowl, including a bowl shell, a plurality of vertical reinforcing ribs are provided on the inner arc wall of the bowl shell, and the vertical reinforcing ribs are arranged at equal intervals. A connecting ring rib is provided between the plurality of vertical reinforcing ribs. An inner liner is provided between the inner sides of the plurality of vertical reinforcing ribs. A heat-insulating cavity is formed between the plurality of vertical reinforcing ribs and the inner liner. Reinforcing paper is provided on the inner arc surface of the inner liner. A waterproof oil coating is applied to the inner side of the reinforcing paper. A plurality of supporting ribs are provided at the lower end of the bowl shell, and the plurality of supporting ribs are arranged at equal intervals. A transverse connecting rib is provided between the plurality of supporting ribs. A label groove is provided on the front side of the bowl. The bowl shell is made of high-strength synthetic fiber material, the inner liner is made of plant fiber reinforced material, and the reinforcing paper is made of nanocellulose material.

[0006] As a further improvement of this utility model, auxiliary plates are provided on the left and right sides of the bowl shell, the left and right positions of the two auxiliary plates are corresponding, and multiple protrusions are provided on the upper and lower sides of each auxiliary plate.

[0007] As a further improvement of this utility model, the bottom of the bowl is curved with rolled edges.

[0008] As a further improvement of this utility model, a bowl lid is snapped onto the upper end of the bowl body, and the inside of the bowl lid has multiple vent holes, which are arranged at equal intervals.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the multiple vertical reinforcing ribs and connecting ring ribs within the paper bowl together form a stable support structure, effectively improving the bowl's compressive strength and preventing deformation under stress. The heat-insulating cavity formed between the inner liner and the reinforcing ribs not only enhances structural stability but also provides a certain degree of heat preservation. The supporting ribs and horizontal connecting ribs improve the bottom load-bearing capacity, preventing the bottom of the paper bowl from collapsing or deforming when stacked or filled with heavy objects. The bowl shell is made of high-strength synthetic fiber material, the inner liner is reinforced with plant fiber, and the reinforcing paper is made of nanocellulose. This anti-deformation paper bowl, using a high-strength synthetic fiber shell, a plant fiber reinforced inner liner, and nanocellulose reinforced paper, has excellent structural strength and anti-deformation capabilities. Synthetic fibers provide high pressure resistance, plant fibers are environmentally friendly and durable, and the nanocellulose reinforcement layer enhances overall toughness and stability. The ribs set inside the bowl strengthen its strength, and combined with the bowl's own material reinforcement, effectively preventing deformation, improving its practicality, and enhancing the user experience.

[0011] Secondly, by holding the auxiliary plate with both hands, the bowl full of food can be quickly transferred, and the protrusion can also prevent the bowl from slipping out of your hand when transferring the bowl through the auxiliary plate, making it easy for people to use.

[0012] Thirdly, the curved edge at the bottom makes it more comfortable for people to hold, avoiding a cutting sensation in the palm and reducing the user experience. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown in Figure 3, an anti-deformation paper bowl includes a bowl shell 101. Multiple vertical reinforcing ribs 201 are arranged at equal intervals on the inner arc wall of the bowl shell 101. A connecting ring rib 202 is provided between the multiple vertical reinforcing ribs 201. An inner liner 107 is provided between the inner surfaces of the multiple vertical reinforcing ribs 201. A heat-insulating cavity is formed between the multiple vertical reinforcing ribs 201 and the inner liner 107. Reinforcing paper 108 is provided on the inner arc surface of the inner liner 107. A waterproof oil coating 109 is applied to the inner surface of the reinforcing paper 108. The waterproof oil coating 109 effectively blocks liquid penetration, maintaining the structural stability of the paper bowl. The lower end of the shell 101 is provided with multiple support ribs 203, which are arranged at equal intervals. A horizontal connecting rib 204 is provided between the multiple support ribs 203. A label slot 106 is provided on the front side of the bowl. The label slot 106 allows people to attach food labels, so that they can know what food is inside without opening the paper bowl. At the same time, the label slot 106 also has a label positioning function, making the label position more uniform and beautiful. The bottom 105 of the bowl is curved and rolled. When people hold the bowl, the curved and rolled edge at the bottom makes it more comfortable to hold, avoiding the feeling of cutting the palm and reducing the user experience.

[0022] The multiple vertical reinforcing ribs 201 and connecting ring ribs 202 set in the paper bowl together form a stable support structure, which effectively improves the compressive strength of the bowl and prevents deformation under stress. The heat insulation cavity formed between the inner liner 107 and the reinforcing ribs not only enhances the structural stability, but also has a certain heat preservation effect. The support ribs 203 and the transverse connecting ribs 204 improve the bottom load-bearing capacity and prevent the bottom of the paper bowl from collapsing and deforming when stacked or filled with heavy objects.

[0023] like Figure 5As shown, the outer shell 101 is made of high-strength synthetic fiber material, the inner liner is made of plant fiber reinforced material, and the reinforcing paper 108 is made of nanocellulose material. The anti-deformation paper bowl, which uses a high-strength synthetic fiber outer shell 101, a plant fiber reinforced inner liner 107, and nanocellulose reinforced paper 108, has excellent structural strength and anti-deformation ability. The synthetic fiber provides high pressure resistance, the plant fiber is environmentally friendly and durable, and the nanocellulose reinforcing layer improves the overall toughness and stability. Through the above materials, the paper bowl is not easily deformed when holding hot food or under pressure.

[0024] like Figure 1 As shown, a bowl lid 102 is attached to the upper end of the bowl body. The bowl lid 102 has multiple vent holes 103 inside. By placing the bowl lid 102 on the bowl body, the food inside can be sealed to prevent external contamination. The vent holes 103 can also balance the internal and external air pressure to prevent the lid from being too tightly sealed and difficult to remove.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 4, auxiliary plates 104 are provided on the left and right sides of the bowl shell 101 respectively. Each auxiliary plate 104 has multiple protrusions on its upper and lower sides. People can quickly transfer the bowl full of food by holding the auxiliary plate 104 with both hands. The protrusions can also prevent the bowl from slipping out of their hands when transferring the bowl through the auxiliary plate 104.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
