[0001] The utility model relates to the technical field of paper bowls, in particular to a paper bowl which is resistant to thermal deformation. Background Art

[0002] Paper bowls are a kind of paper container made by mechanically processing and gluing base paper (white cardboard) made from chemical wood pulp. They have a bowl-shaped appearance and are safe, hygienic, light and convenient. Paper bowls for different purposes are coated with different materials inside, making them suitable for different environments. They can be used in public places, hotels, and restaurants. They are disposable items. Since the advent of paper bowls, they have quickly become the most vital green tableware in the 21st century due to their safety, hygiene, lightness and convenience in carrying.

[0003] Upon investigation, a Chinese utility model patent discloses a paper bowl with good stability (publication number: CN217348664U), which includes a side panel, which is in the shape of a truncated cone with a larger upper part and a smaller lower part. A bottom panel is arranged inside the side panel, and the bottom panel is circular. The outer edge of the bottom panel is fixedly connected to the inner wall of the side panel, and a support ring is arranged inside the side panel, and the lower end of the support ring is folded inward to form a water-retaining flange.

[0004] Although the above patent can increase the stability of the paper bowl by setting the side panels, bottom plate and support ring, so that the paper bowl is not easily deformed when the user is eating, the bowl edge of the paper bowl in the above patent is set on one side and the bowl wall is very thin. When holding hot water, hot soup or food, the bowl wall of the paper bowl is easily deformed by heat, making the paper bowl difficult to hold.

[0005] Therefore, the utility model provides a paper bowl that is resistant to thermal deformation to solve the above-mentioned problem. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a paper bowl which is resistant to heat deformation. Figure 1 , Figure 2 and Figure 5 As shown, the paper bowl includes an outer wall layer 1, an inner liner 11 arranged inside the outer wall layer 1, a sealing plate 12 arranged between the outer wall layer 1 and the inner liner 11 for sealing the open end, and a support plate 2 fixedly mounted on the outer wall layer 1 and in contact with the inner liner 11, wherein a plurality of support plates 2 are provided, and the plurality of support plates 2 are folded to form a three-dimensional structure and are placed between the outer wall layer 1 and the inner liner 11, a support block 3 for supporting the paper bowl is fixedly connected to the inner liner 11, and the support plate 2 is fixedly connected to the sealing plate 12.

[0030] The inner pot 11 of the paper bowl is filled with food. After the food is loaded into the inner pot 11, heat is transferred to the paper bowl. After the inner pot 11 is heated, heat is transferred to the support plate 2. At the same time, there is a gap between the inner pot 11 and the outer wall layer 1, which produces a heat insulating effect for the outer wall layer 1. When the user picks up the paper bowl to prepare to eat, the support plate 2 provides support for the inner pot 11 and the outer wall layer 1, so that the gap between the inner pot 11 and the outer wall layer 1 is not easy to deform when the user picks up the paper bowl, which is convenient for use. At the same time, through the setting of the sealing plate 12, when the food passes through the edge of the paper bowl, the soup on the food is blocked by the sealing plate 12 and is not easy to penetrate into the gap of the paper bowl. Then the support block 3 is set between the inner pot 11 and the outer wall layer 1 to provide support for the outer wall layer 1, thereby improving the structural strength of the paper bowl and facilitating use.

[0031] Furthermore, in order to improve the structural strength of the paper bowl, e.g. Figure 2 , Figure 3 and Figure 5 As shown, a plurality of support blocks 3 are provided, and the plurality of support blocks 3 are arranged in a circular array on the inner container 11 .

[0032] The support block 3 increases the contact area between the inner container 11 and the outer wall layer 1, so that when the paper bowl is used by the user, the support block 3 increases the structural strength of the paper bowl and makes it difficult for the paper bowl to be deformed.

[0033] Furthermore, in order to place the paper bowl firmly on a horizontal plane, the bottom surface of the outer wall layer 1 is fixedly connected to a bottom plate 5, the inner surface of the bottom plate 5 is fixedly connected to a connecting plate 6 for increasing the supporting strength, and a connecting column 61 is fixedly connected between the connecting plate 6 and the outer wall layer 1.

[0034] After the paper bowl is filled with food and placed on the table, the bottom plate 5 contacts the table, so that a gap exists between the outer wall layer 1 and the table, making it difficult for the heat of the food to be transmitted to the table, thereby further keeping the food warm. When the user picks up the paper bowl, the user's fingers contact the bottom plate 5 and the sealing plate 12, so that the user's fingers are not likely to come into direct contact with the food, avoiding the user from being scalded by the food when picking up the paper bowl. At the same time, by arranging the connecting plate 6 and the connecting column 61, the structural strength of the bottom of the paper bowl is improved, so that the paper bowl is not easily deformed when used.

[0035] Furthermore, in order to prevent the bottom of the paper bowl from being easily deformed when the paper bowl is used, Figure 2 and Figure 3 As shown, a connection block 4 is fixedly connected to the inner bottom surface of the outer wall layer 1 , and one end of the connection block 4 away from the outer wall layer 1 is fixedly connected to the inner liner 11 .

[0036] After the paper bowl is filled with food, the connecting block 4 supports the bottom of the inner pot 11, and at the same time, the outer wall layer 1 provides support for the inner pot 11 through the connecting block 4, thereby improving the structural strength of the bottom of the paper bowl, so that the paper bowl is not easily deformed when the user picks up the paper bowl.

[0037] In order to improve the connection strength of the connection block 4, the cross-section of the connection block 4 is hexagonal, and a plurality of connection blocks 4 are provided. The plurality of connection blocks 4 are evenly arranged between the outer wall layer 1 and the inner liner 11, and the plurality of connection blocks 4 are fixedly connected.

[0038] In order to increase the connection strength between the inner liner 11 and the outer wall layer 1, the connecting block 4 can be round, square or oval, and multiple connecting blocks 4 are fixedly connected to form a whole, which is easy to use and prevents the paper bowl from being deformed when being picked up.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
