DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1-6 The present application provides an embodiment: a wok rice aluminum bowl, comprising a body 1, a cover 2 and a bowl body 3,

[0032] The main body 1 is composed of a lid 2 and a bowl 3. The opening of the bowl 3 is provided with an outwardly rolled edge 304. The bottom of the bowl 3 is provided with an annular base 301, the height of which is 2mm to 10mm.

[0033] The lid 2 is located on top of the main body 1 and is used to cover the opening of the bowl 3 to maintain the temperature and humidity of the food. The lid 2 is circular in shape, and its diameter matches the opening diameter of the bowl 3, ensuring that the lid 2 can tightly cover the bowl 3.

[0034] The bowl 3 is located at the bottom of the main body 1 and is used to hold food. The bowl 3 is cylindrical in shape to ensure good stability and durability in high-temperature environments.

[0035] The opening of the bowl body 3 is provided with an outwardly rolled edge 304, the height of which is 5mm to 15mm and the width is 3mm to 8mm. The design of the edge 304 not only increases the strength of the bowl body 3, but also makes it easier for users to hold during handling and cleaning, preventing burns.

[0036] The bowl body 3 has a ring-shaped base 301 at its bottom. The ring-shaped base 301 has a height of 2mm to 10mm and a width of 10mm to 20mm. The ring-shaped base 301 is designed to increase the stability of the bowl body 3 and prevent it from tipping over during heating. The bottom surface of the ring-shaped base 301 is treated with an anti-slip coating to ensure that it can be placed stably on heating equipment made of different materials.

[0037] The inner side of the annular base 301 is provided with a bowl bottom 302. The bowl body 3 and the bowl bottom 302 are provided with a food-grade PE film 307, an aluminum foil layer 303 and a polyethylene film 306 from the inside to the outside.

[0038] The food-grade PE film 307, aluminum foil layer 303 and polyethylene film 306 are connected by a hot-pressing composite process, and the outer surface of the bowl body 3 is provided with anti-slip texture.

[0039] like Figure 1 As shown, the inner side of the annular base 301 of this utility model is provided with a bowl bottom 302. The bowl body 3 and the bowl bottom 302 are connected together by a specific composite process to form an integral structure.

[0040] The bottom 302 and the inner and outer sides of the bowl body 3 are both provided with multiple layers of composite material, specifically including:

[0041] Food-grade PE film 307: This film layer comes into direct contact with food, has good food safety and chemical stability, and can effectively prevent food from coming into direct contact with the container, ensuring food safety.

[0042] Aluminum foil layer 303: Located on the outer side of the food-grade PE film 307, it has good barrier properties and can effectively block moisture, gas and light, maintaining the freshness and taste of the food.

[0043] Polyethylene film 306: Located on the outer side of the aluminum foil layer 303, it has strong mechanical strength and heat resistance, which can protect the aluminum foil layer 303 from damage by the external environment, while providing good heat sealing performance.

[0044] Composite process

[0045] The food-grade PE film 307, aluminum foil layer 303 and polyethylene film 306 are connected by hot pressing composite process. The specific steps are as follows:

[0046] Pre-treatment: The food-grade PE film 307, aluminum foil layer 303 and polyethylene film 306 are surface treated to ensure that the surface of each layer of material is clean and free of impurities.

[0047] Layered placement: The pretreated materials are layered in the order of food-grade PE film 307, aluminum foil layer 303 and polyethylene film 306.

[0048] Hot pressing composite: The layered materials are placed in a hot pressing composite machine, and appropriate temperature and pressure are set to tightly bond the materials under high temperature and pressure, forming an integrated composite structure.

[0049] The outer surface of the bowl body 3 is provided with anti-slip texture. The design of anti-slip texture not only can improve the holding stability of the bowl body during use, but also can increase the aesthetic appearance. The specific form of anti-slip texture can be a concave-convex geometric pattern, a dot-shaped protrusion or any other form of texture design.

[0050] The cover body 2 includes a bowl cover 204 that is buckled on the top of the bowl body 3, and the edge position of the bowl cover 204 is provided with a clamping edge 201 that matches the edge 304.

[0051] The inner diameter of the clamping edge 201 and the outer diameter of the edge 304 are different by 1mm to 3mm, and the inner side of the edge 304 is provided with a buffer opening 305, and the width of the buffer opening 305 is 3mm to 5mm.

[0052] The top end of the clamping edge 201 is provided with a buckle edge 205, and the center position of the bowl cover 204 is provided with a sunken groove 203, and the connection between the sunken groove 203 and the bowl cover 204 is provided with a reinforcing rib ring 206.

[0053] The center position of the sunken groove 203 is provided with a steam through hole 202.

[0054] The cover body 2 comprises a bowl cover 204 buckled on the top of the bowl body 3.

[0055] The edge position of the bowl cover 204 is provided with a clamping edge 201 matched with the edge 304 of the bowl body 3. The design of the clamping edge 201 enables the bowl cover 204 to be tightly buckled on the bowl body 3, ensuring the sealing effect. Specifically, the inner diameter of the clamping edge 201 is 1mm to 3mm different from the outer diameter of the edge 304, which can ensure the tightness of clamping and facilitate the user to easily buckle and separate.

[0056] In order to further optimize the sealing effect and user experience, the inner side of the edge 304 is provided with a buffer opening 305. The width of the buffer opening 305 is 3mm to 5mm, which mainly provides a certain buffer space during buckling to avoid damage to the bowl cover 204 or the bowl body 3 due to excessive force. At the same time, the buffer opening 305 can also adjust the internal air pressure to a certain extent to prevent the cover body 2 from accidentally opening due to air pressure changes.

[0057] The top end of the clamping edge 201 is provided with a buckling edge 205, which enhances the buckling force of the clamping edge 201, making the bowl cover 204 more stable in the buckling state. The thickness of the buckling edge 205 is 2mm to 4mm, and the material is the same as that of the bowl cover 204, ensuring the coordination and consistency of the overall structure.

[0058] The center position of the bowl cover 204 is provided with a sunken groove 203, and the depth of the sunken groove 203 is 5mm to 10mm. Its main role is to concentrate steam to prevent steam from directly contacting food, thereby maintaining the taste and nutrition of food. The connection between the sunken groove 203 and the bowl cover 204 is provided with a reinforcing rib ring 206, and the thickness of the reinforcing rib ring 206 is 1mm to 2mm. Its main role is to enhance the overall strength of the bowl cover 204 to prevent deformation in a high-temperature environment.

[0059] The center position of the sunken groove 203 is provided with a steam through hole 202, and the diameter of the steam through hole 202 is 5mm to 8mm. Its main role is to exhaust internal steam to prevent excessive internal pressure due to steam accumulation, affecting the safety of use. The design position and size of the steam through hole 202 are accurately calculated, which can effectively exhaust steam without affecting the overall sealing performance of the bowl cover 204.
