Description

Technical Field

[0001] This utility model relates to the field of disposable bowls technology, and in particular to a heat-insulating and non-slip disposable bowl. Background Technology

[0002] Disposable bowls have many advantages in modern society, especially in catering services, outdoor activities, and emergencies. They do not need to be washed after use, saving time and water resources. Using a new bowl each time reduces the risk of cross-contamination, especially in public places and large-scale events.

[0003] Disposable tableware is very common and practical in the catering industry. It offers convenience, hygiene, and cost-effectiveness, and is widely used, especially in fast food, takeout, and large events. Bulk purchasing of disposable tableware is generally cheaper, suitable for large-scale use, and available in various materials, colors, patterns, and shapes to meet the needs of different catering brands and events.

[0004] As described in Chinese Patent Publication No. CN202051099U, a disposable bowl-shaped lunchbox has a rim, a wall, and a bottom. The rim is a regular N-gon (N≥5), and the bottom is a regular polygon corresponding to the rim. A diagonal reinforcing rib extends from each vertex of the polygonal rim to the bottom, and every two adjacent reinforcing ribs form a triangle with a vertex of the bottom edge. The beneficial effects of this invention are: the triangular ribs distribute the tensile force borne by the lunchbox evenly around the bowl wall, effectively transferring and decomposing the pressure or tension applied in one direction. This reinforcing rib is also more effective than straight ribs, which can only disperse forces in the vertical direction, while the triangular ribs can strengthen the tensile stress limit both horizontally and vertically.

[0005] Currently, in the catering industry, as people's requirements for food hygiene are getting higher and higher, the traditional practice of repeatedly washing tableware by restaurant owners has gradually been phased out in large restaurants, and disposable tableware has been basically replaced. This can ensure the hygiene and safety of people while eating to the greatest extent. However, most disposable tableware is made of single-layer environmentally friendly heat-insulating plastic material. Although it is environmentally friendly and non-toxic, it can easily cause burns to the user's hands when holding some hot food. Even if you are not burned, it is easy to make it impossible to handle due to the excessive temperature. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a heat-insulating and non-slip disposable bowl.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a heat-insulating and non-slip disposable bowl, including a bowl body, a bowl bottom at the lower end of the bowl body, the bowl body and the bowl bottom being an integral structure, a heat-insulating sleeve covering the outside of the bowl body, and non-slip protrusions provided on the outer wall of the heat-insulating sleeve, a plurality of non-slip protrusions being provided and distributed in a ring along the outer wall of the heat-insulating sleeve, the heat-insulating sleeve and the non-slip protrusions being an integral structure;

[0009] The inner side of the heat insulation sleeve is provided with an adhesive strip, one side of which is adhered to the inner ring wall of the heat insulation sleeve. Several adhesive strips are provided and are evenly distributed on the inner side of the heat insulation sleeve.

[0010] The heat insulation sleeve comprises, from the inside out, a moisture-proof layer, a heat insulation layer, and a deformation-resistant layer. The deformation-resistant layer is embedded in the heat insulation layer, and the moisture-proof layer is coated on the outer ring wall of the heat insulation layer.

[0011] In detail, both the bowl body and the bottom are made of environmentally friendly plastic materials.

[0012] In detail, the bottom of the bowl has a circular structure and a thickness of not less than five millimeters.

[0013] In detail, the moisture-proof layer is made of polyethylene coating material.

[0014] In detail, the insulation layer is made of polyurethane foam material.

[0015] In detail, the anti-deformation layer is made of rigid polypropylene sheet material, and the sheet structure has the same shape as the heat insulation sleeve, both being ring structures.

[0016] In detail, the bowl body has a structure that is wide at the mouth and narrow at the bottom, and the heat insulation sleeve is fitted to fit the bowl body.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. The bowl and heat-insulating sleeve work together to create a double-layer structure. The bowl is made of environmentally friendly plastic, meeting food safety standards. It can hold food and is disposable, clean, and hygienic. The heat-insulating sleeve is securely attached to the bowl via adhesive strips, preventing it from coming detaching during use. The heat-insulating sleeve provides insulation and prevents burns when holding hot soup or other hot foods. The anti-slip protrusions on the outer wall of the heat-insulating sleeve also provide a non-slip grip when holding it.

[0019] 2. The heat insulation sleeve structure consists of a moisture-proof layer, a heat insulation layer, and an anti-deformation layer, which further improves the stable heat preservation effect during meals. The moisture-proof layer can block external water stains, preventing water stains and dirt from adhering to the heat insulation sleeve during use, thus avoiding hygiene and safety issues and ensuring that hands are covered with stains every time you handle the bowl. The heat insulation layer, made of polyurethane material, effectively provides heat insulation, thus preventing burns when holding the bowl. The built-in anti-deformation layer has a spring-loaded effect when the heat insulation sleeve deforms, ensuring that the heat insulation sleeve will not deform or break due to pressure before being assembled with the bowl.

[0025] 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.

[0026] Reference Figures 1-4 A heat-insulating and non-slip disposable bowl includes a bowl body 1, a bowl bottom 11 at the lower end of the bowl body 1, the bowl body 1 and the bowl bottom 11 are an integral structure, the outside of the bowl body 1 is wrapped with a heat-insulating sleeve 12, and a number of anti-slip protrusions 13 are provided on the outer ring wall of the heat-insulating sleeve 12, and the anti-slip protrusions 13 are arranged in a ring along the outer wall surface of the heat-insulating sleeve 12, and the heat-insulating sleeve 12 and the anti-slip protrusions 13 are an integral structure;

[0027] An adhesive strip 14 is provided on the inner side of the heat insulation sleeve 12. One side of the adhesive strip 14 is adhered to the inner ring wall of the heat insulation sleeve 12. Several adhesive strips 14 are provided and are evenly distributed on the inner side of the heat insulation sleeve 12.

[0028] The heat insulation sleeve 12 includes, from the inside out, a moisture-proof layer 121, a heat insulation layer 122, and a deformation-resistant layer 123. The deformation-resistant layer 123 is embedded in the heat insulation layer 122, and the moisture-proof layer 121 is coated on the outer ring wall of the heat insulation layer 122.

[0029] It should be further noted that both the bowl body 1 and the bowl bottom 11 are made of environmentally friendly plastic materials. Environmentally friendly plastics are made from natural raw materials, such as starch and vegetable oil, which can be decomposed by microorganisms in the natural environment, reducing pollution to soil and water. Biodegradable plastics can decompose in a relatively short time, reducing the problem of long-term accumulated plastic waste. Environmentally friendly plastics are usually made from renewable resources, such as corn starch, sugarcane, and cassava, reducing dependence on non-renewable resources such as petroleum. Environmentally friendly plastics usually do not contain harmful chemicals, such as bisphenol A (BPA) and phthalates, making them safer for human health.

[0030] It should be further explained that the bottom of the bowl 11 is a circular structure with a thickness of not less than five millimeters. The circular bottom structure of the bowl 11 can insulate the heat when hot food is placed inside the bowl 1, so that the bowl 1 will not burn the table surface when placed on it. At the same time, it provides a stable support for the bowl 1.

[0031] It should be further noted that the moisture barrier 121 is made of polyethylene coating material. The temperature at which polyethylene releases its toxicity is between 350-400 degrees Celsius. The temperature of food is much lower than the temperature at which it releases its toxicity, so it does not affect the safety of use. The polyethylene coating has good resistance to most acids, alkalis and salts, can effectively prevent corrosion, has excellent waterproof performance, has high abrasion resistance, can resist friction and wear, and has high ductility, can remain unbroken when stretched.

[0032] It should be further noted that the insulation layer 122 is made of polyurethane foam. Since polyurethane foam only releases toxicity at around 200 degrees Celsius, it is safe to use when storing hot food, as the temperature of the food is much lower than the temperature at which the toxicity is released. Polyurethane foam has a very low thermal conductivity, which can effectively block heat conduction and provide excellent insulation. Polyurethane foam has a low density and is lightweight, making it easy to transport and install. Polyurethane foam has good resistance to most chemicals and is not easily corroded or dissolved.

[0033] It should be further noted that the anti-deformation layer 123 is made of rigid polypropylene sheet material, and the sheet structure is the same as the shape of the heat insulation sleeve 12, both being annular structures. Polypropylene has a melting point of approximately 160-170 degrees Celsius, which allows it to remain stable at higher temperatures. Polypropylene has a low density and is lightweight, making it easy to transport and install. Polypropylene has good processability and can be molded by injection molding, extrusion, blow molding, etc., making it suitable for manufacturing products of various complex shapes. Polypropylene does not contain harmful chemicals, meets food-grade standards, and is suitable for food packaging.

[0034] It should be further noted that the bowl body 1 has a wide mouth and a narrow bottom, and the heat insulation sleeve 12 is fitted to fit the bowl body 1.

[0035] Working principle: The bowl body 1 and the heat insulation sleeve 12 work together to create a double-layer structure. The bowl body 1 is made of environmentally friendly plastic material, which meets the standards for safe consumption. It can hold food and is disposable, clean and hygienic. The heat insulation sleeve 12 is connected to the bowl body 1 by the adhesive strip 14, which can firmly fix it to the bowl body 1 and prevent it from coming off during use. The heat insulation sleeve 12 can provide heat insulation and prevent scalding when hot soup or other hot foods are stored in the bowl body 1. The anti-slip protrusions 13 on the outer wall of the heat insulation sleeve 12 can provide anti-slip protection when holding the heat insulation sleeve 12.

[0036] The heat insulation sleeve 12, composed of a moisture-proof layer 121, a heat insulation layer 122, and an anti-deformation layer 123, further enhances the stable heat preservation effect of the heat insulation sleeve 12 during meals. The moisture-proof layer 121 blocks external water stains, preventing water stains and dirt from adhering to the heat insulation sleeve 12 during use, thus avoiding hygiene and safety issues and ensuring that hands are covered with dirt every time the bowl is handled. The heat insulation layer 122, made of polyurethane material, effectively provides heat insulation, preventing burns when holding the bowl 1. The built-in anti-deformation layer 123 has a spring-loaded effect when the heat insulation sleeve 12 deforms, ensuring that the heat insulation sleeve 12 will not deform or break due to compression before being assembled with the bowl 1.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
