Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper bowl technology, and in particular relates to a reinforced paper bowl that is heat-proof and leak-proof. Background Technology
[0002] Traditional paper bowls present several problems during use. Firstly, due to the nature of paper, their heat insulation is poor. When filled with hot food, the surface temperature rises rapidly, making it easy for users to burn themselves if they handle the bowl directly. Secondly, the structural design of traditional paper bowls is flawed; there is a lack of effective sealing and leak-proof measures between the rim and the bowl body. Food or soup can easily leak from the rim, staining tabletops or clothing and causing inconvenience to the user.
[0003] Furthermore, traditional paper bowls are not very strong, and when filled with heavy or large amounts of food, they are prone to deformation or even breakage, leading to food spillage, waste, and cleaning difficulties. These problems seriously affect the user experience and practicality of paper bowls and urgently need to be solved through technological innovation.
[0004] To address the aforementioned problems, this utility model document proposes a reinforced paper bowl that is heat-resistant and leak-proof. Utility Model Content
[0005] The purpose of this utility model is to provide a reinforced paper bowl that is heat-resistant and leak-proof. Through structural innovation and material optimization, it effectively solves the problems of poor heat insulation, easy leakage, and low strength of traditional paper bowls, improves the practicality and safety of paper bowls, provides users with a more convenient and comfortable dining experience, and solves existing technical problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] A heat-resistant and leak-proof reinforced paper bowl, designed to prevent food from leaking out during use, includes:
[0008] An inner bowl for holding food, with an outer shell fixed to its surface. A support ring for supporting the outer shell and the inner bowl is fixed to the bottom of the outer shell. A set of collection components is provided inside the support ring. The collection components are used to collect food that leaks into the inner bowl to avoid contamination.
[0009] In order to block the heat inside the inner bowl, a heat insulation gap is formed between the outer shell and the inner bowl. A set of reinforcing components is provided in the heat insulation gap to increase the strength of the outer shell and the inner bowl.
[0010] Optionally, the collecting assembly includes a receiving groove formed at the top of a support ring, the support ring having an upward-facing semi-circular cross-section.
[0011] Optionally, the outer shell is narrower at the top and wider at the bottom to collect food that leaks out of the inner bowl.
[0012] When food spills out of the inner bowl during eating, it is guided downwards by the inclined outer shell, which is narrower at the top and wider at the bottom. The support ring is located at the bottom of the outer shell and can receive and hold food or soup that rolls off the surface of the outer shell, effectively preventing food or soup from spilling onto the table or hands.
[0013] Optionally, the reinforcing assembly includes multiple reinforcing plates, all of which are fixed between the outer shell and the inner bowl, and are evenly distributed within the heat insulation gap.
[0014] Optionally, a plurality of support plates are uniformly fixed on the surface of the outer casing;
[0015] When holding the support ring with your palm, your thumb does not need to press on the rim of the inner bowl; it only needs to press on the support plate, which can effectively prevent direct contact with the inner bowl.
[0016] Optionally, the multiple reinforcing plates and multiple support plates are all made of corrugated cardboard.
[0017] In this application, when food inside the inner bowl leaks outward through the bowl rim during eating, it is guided downward by the inclined outer shell, which is narrower at the top and wider at the bottom. The support ring is set at the bottom of the outer shell and can receive and accommodate food or soup rolling off the surface of the outer shell, effectively preventing food or soup from leaking onto the table or hands.
[0018] When holding the support ring with your palm, your thumb does not need to press on the rim of the inner bowl; it only needs to press on the support plate, which can effectively prevent direct contact with the inner bowl.
[0019] In this invention, a reinforced paper bowl that is heat-resistant and leak-proof features an outer shell and an inner bowl with an insulating gap between them. This effectively blocks heat transfer from the inner bowl and reduces the surface temperature of the outer shell, preventing burns to the user. Simultaneously, the tapered structure of the outer shell (narrower at the top and wider at the bottom) and the receiving groove of the support ring form a collection component that can collect food or liquid leaking from the inner bowl, preventing stains on the table or clothing and improving ease of use.
[0020] In this invention, the heat-proof and leak-proof reinforced paper bowl effectively solves the problems of poor heat insulation, easy leakage, and low strength of traditional paper bowls through structural innovation and material optimization, thereby improving the practicality and safety of the paper bowl and providing users with a more convenient and comfortable dining experience.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0030] In one embodiment:
[0031] Please see Figures 1-3 As shown, this embodiment provides a heat-resistant and leak-proof reinforced paper bowl to prevent food from leaking out during use. The paper bowl mainly includes an outer shell 1, an inner bowl 2, a support ring 3, a collecting component, a reinforcing component, and a support plate 5.
[0032] The inner bowl 2 is used to hold food, and its surface is fixedly connected to the outer shell 1. The outer shell 1 adopts a tapered structure that is narrower at the top and wider at the bottom. This structure not only makes it easy to hold but also effectively collects food that leaks from the inner bowl 2. A support ring 3 is fixedly connected to the bottom of the outer shell 1. The support ring 3 supports the outer shell 1 and the inner bowl 2. Its cross-section is a semi-circular shape with the opening facing upwards, and a receiving groove 4 is opened at the top to form a collection component. When food in the inner bowl 2 leaks outwards along the rim, the tapered structure of the outer shell 1 guides the food, causing it to roll down the surface of the outer shell 1 into the receiving groove 4 of the support ring 3, preventing food or soup from leaking onto the table or hands.
[0033] A heat-insulating gap 6 is formed between the outer shell 1 and the inner bowl 2 to block heat from the inner bowl 2 and prevent burns to the user. A reinforcing component is installed inside the heat-insulating gap 6. The reinforcing component includes multiple reinforcing plates 7, which are evenly fixed between the outer shell 1 and the inner bowl 2 to enhance the strength of the outer shell 1 and the inner bowl 2 and prevent the paper bowl from deforming or breaking during use.
[0034] In another embodiment: refer to Appendix Figure 1 -Appendix Figure 3 A reinforced paper bowl designed to prevent scalding and leaks also includes multiple support plates 5 evenly fixed to the surface of the outer shell 1. When the palm supports the support ring 3, the thumb does not need to press on the rim of the inner bowl 2; it only needs to press on the support plate 5, effectively preventing direct contact with the inner bowl 2 and avoiding burns. Both the multiple reinforcing plates 7 and the multiple support plates 5 are made of corrugated cardboard, which has good strength and heat insulation properties, and is inexpensive, making it suitable for mass production.
[0035] In practical use, food is placed inside the inner bowl 2, while the outer shell 1 and support ring 3 provide support and protection. If food accidentally spills, the inclined structure of the outer shell 1 and the receiving groove 4 of the support ring 3 collect the spilled food, keeping the tabletop clean. The reinforcing plate 7 and support plate 5 enhance the strength and heat insulation performance of the paper bowl, respectively, improving the user experience.
