Description

Technical Field

[0001] This utility model relates to the field of paper bowl-related products, specifically a leak-proof disposable paper bowl. Background Technology

[0002] Disposable paper bowls are paper containers made by mechanically processing and bonding base paper (white cardboard) made from chemical wood pulp. Disposable paper bowls are characterized by safety, hygiene, lightness and convenience. They are disposable items that can be used in public places, restaurants and eateries. As people's pace of life becomes faster and faster, fast food plays an increasingly important role in people's daily diet. Disposable paper bowls are widely used in daily life because of their portability and cleanliness.

[0003] However, existing disposable paper bowls are prone to leaking soup from the joints when carried, and the bottom corners of the paper bowls are where the flat surface meets the side wall, which is a dead angle in terms of physical structure. When the paper bowl comes into contact with a wet tabletop or tray, or when the liquid it contains spills to the bottom, the water will accumulate at the corners, causing damage to the paper bowl's structure, making it defective. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof disposable paper bowl to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof disposable paper bowl, comprising a bowl body and a bowl lid, wherein a positioning ring is fixedly connected to the inner wall of the bowl lid, an annular groove corresponding to the positioning ring is provided on the outer wall of the bowl body, a moisture-absorbing ring is fixedly connected to the chamfered corner where the inner wall of the bowl lid connects to the positioning ring, and an isolation film is fixedly connected to the inner bottom corner of the bowl body.

[0006] As a preferred embodiment of this utility model, a support ring is fixedly connected to the bottom of the bowl body, and the bottom of the support ring is provided with multiple anti-slip textures arranged at an angle.

[0007] As a preferred embodiment of this invention, the outer ring of the positioning ring is configured with an arc-shaped structure.

[0008] As a preferred embodiment of this invention, the moisture-absorbing ring is made of sponge.

[0009] As a preferred embodiment of this invention, an extension piece is fixedly connected to one side of the bowl lid.

[0010] As a preferred embodiment of this invention, the separator is a cast polypropylene film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This leak-proof disposable paper bowl is assembled by fastening the lid onto the bowl body. At this time, the positioning ring on the inner wall of the lid is inserted into the annular groove on the bowl body. The moisture-absorbing ring installed on the inner wall of the lid can protect the joint between the lid and the bowl body. In case of leakage, the moisture-absorbing ring can absorb the soup. The isolation film installed on the bottom of the bowl body can increase the strength of the bottom corner of the paper bowl and achieve waterproof isolation.

[0013] This leak-proof disposable paper bowl features a moisture-absorbing structure that enhances moisture absorption at the joints, preventing soup from leaking out while also increasing the stability of the bowl's internal corners, making it suitable for widespread use.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-3 This utility model provides an embodiment of a leak-proof disposable paper bowl, comprising a bowl body 1 and a bowl lid 2. A positioning ring 3 is fixedly connected to the inner wall of the bowl lid 2, and an annular groove 4 corresponding to the positioning ring 3 is provided on the outer wall of the bowl body 1. A moisture-absorbing ring 5 is fixedly connected to the chamfer where the inner wall of the bowl lid 2 connects to the positioning ring 3. An isolation film 6 is fixed at the inner bottom corner of the bowl body 1. Specifically, when the bowl lid 2 is fastened onto the bowl body 1, the positioning ring 3 on the inner wall of the bowl lid 2 is inserted into the annular groove 4 on the bowl body 1 to achieve assembly. The moisture-absorbing ring 5 installed on the inner wall of the bowl lid 2 can protect the joint between the bowl lid 2 and the bowl body 1. When soup leaks, the moisture-absorbing ring 5 can absorb the soup. The isolation film 6 installed on the inner bottom of the bowl body 1 can increase the strength of the bottom corner of the paper bowl and achieve waterproof isolation.

[0022] In this embodiment, a support ring 7 is fixedly connected to the bottom of the bowl body 1, and the bottom of the support ring 7 is provided with multiple anti-slip textures arranged at an angle.

[0023] As a technical optimization of this utility model, the bowl body 1 is supported, so that the bowl body 1 is away from the countertop to avoid moisture.

[0024] In this embodiment, the outer ring of the positioning ring 3 is set in an arc shape.

[0025] As a technical optimization of this utility model, the friction force during pressure is reduced.

[0026] In this embodiment, the moisture-absorbing ring 5 is made of sponge.

[0027] As a technical optimization of this utility model, it has a good moisture absorption and moisture retention effect.

[0028] In this embodiment, an extension piece 8 is fixedly connected to one side of the bowl lid 2.

[0029] As a technical optimization of this utility model, the extension piece 8 is used to facilitate the opening and closing of the bowl lid 2.
