DETAILED DESCRIPTION

[0030] When using a plastic cup made of soft material:

[0031] See attached Figures 1 to 4 From the structure shown, it can be understood that an exemplary use process of the anti-scalding device of the present application is:

[0032] A plastic cup comprises a cup body 01, a vacuum ring 03 fixed on the outer wall of the cup body 01, and a coaster 04 placed at the lower end of the cup body 01, wherein the space between the vacuum ring 03 and the outer wall of the cup body 01 is empty, and a cup brim 02 is formed on the upper end of the cup body 01 in a direction away from the axis of the cup body 01, and the coaster 04 can be inverted on the cup brim 02; after hot water is poured into the cup body 01, the user pinches the outer side of the vacuum ring 03 with fingers, and the heat transfer of the hot water can be reduced through the hollow part between the vacuum ring 03 and the outer wall of the cup body 01, thereby avoiding scalding the hands; at the same time, when drinking, when the cup body 01 is tilted, the hot water can flow through the cup brim 02, and the cup brim 02 is used to increase the contact area between the hot water and the air, and to increase the distance and range of the hot water flow, thereby accelerating the heat dissipation and cooling of the hot water, and allowing the user to blow air with the mouth to make the hot water dissipate heat faster, thereby avoiding scalding the mouth;

[0033] In addition, the cup body 01 can be placed on the coaster 04 to separate the cup body 01 from the tabletop to prevent hot water from scalding the tabletop, and the coaster 04 can be used to catch the hot water remaining along the outer wall of the cup body 01 to prevent the hot water from directly flowing onto the tabletop and dirtying it, making it easier to clean the tabletop after use; when not in use, the coaster 04 can be turned upside down on the cup brim 02, so that the inside of the cup body 01 will not be exposed to the air, preventing dust from entering the cup body 01, making it easier to use it directly next time.

[0034] See attached Figures 1 to 4 From the structure shown, it can be understood that an exemplary use process of increasing the support strength of the present application is:

[0035] The inner wall of the vacuum ring 03 is formed with a plurality of support sheets 05 in contact with the outer wall of the cup body 01 along the axis of the vacuum ring 03, and the support sheets 05 are perpendicular to the axis of the cup body 01 in the horizontal direction. In the case of a plastic cup made of soft plastic, when the vacuum ring 03 is pinched by fingers, the vacuum ring 03 is easily deformed due to material problems and thus contacts the outer wall of the cup body 01, resulting in increased heat transfer efficiency. Therefore, the support sheets 05 can be used to form the vacuum ring 03 from the inside to avoid direct contact between the vacuum ring 03 and the outer wall of the cup body 01, thereby further enhancing the heat insulation effect of the vacuum ring 03 and ensuring that the fingers will not be burned when pinching the vacuum ring 03.

[0036] At the same time, the support sheet 05 can increase the strength of the outer wall of the cup body 01 to prevent the outer wall of the cup body 01 from bending in the vertical direction, thereby improving the anti-bending ability of the cup body 01;

[0037] Furthermore, the outer wall surface of the vacuum ring 03 is a frosted surface, which can increase the friction between the finger and the vacuum ring 03, avoid the situation of slipping and falling out of the hand, and facilitate the user to control the plastic cup.

[0038] See attached Figures 1 to 5 From the structure shown, it can be understood that an exemplary use process of increasing the heat dissipation area of the present application is:

[0039] The lower end of the cup body 01 is inwardly recessed to form a concave tower 06, and the middle part of the coaster 04 is formed with a protrusion 16 that can be buckled in the concave tower 06; the concave tower 06 is used to increase the contact area between the cup body 01 and the air, thereby improving the heat dissipation effect and efficiency. At the same time, when the concave tower 06 is stuck on the protrusion 16, the stability of the cup body 01 placed on the coaster 04 can be increased to prevent the cup body 01 from accidentally tipping over. At the same time, the coaster 04 is used to increase the contact area with the desktop, further improving the stability of the cup body 01 placed on the desktop.

[0040] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary use process of increasing the viewing experience of the present application is:

[0041] It also includes a decorative plug 17 that can be embedded in the concave tower 06, and a decorative object is formed on the upper end of the decorative plug 17. During use, the decorative plug 17 provided with the decorative object can be embedded in the concave tower 06, so that during use, the user can observe the decoration inside the cup body 01 to increase the ornamental value, and the decoration can be made into a variety of styles to meet the preferences of users with different styles.

[0042] See attached Figures 1 to 12 From the structure shown, it can be understood that an exemplary use process of increasing the thermal insulation effect of the present application is:

[0043] Side ears 15 are formed on both sides of the vacuum ring 03. The cup body 01 made of hard material will not deform during use, and the user's fingers can stably pinch the vacuum ring 03. In order to increase the heat insulation effect, the user's fingers can enter the side ears 15 to pick up the plastic cup, thereby extending the distance between the fingers and the cup body 01 through the side ears 15, reducing the heat transfer efficiency, and further protecting the fingers from burns.

[0044] When using the plastic cup when it is made of hard material:

[0045] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary use process of adding brewing material in the present application is:

[0046] The plastic cup is made of hard plastic, and the upper end of the concave tower 06 is fixedly connected with a clamping ring 07, and a material frame 08 is detachably connected to the clamping ring 07. The upper end of the material frame 08 is open and is buckled with a material cover 09. The brewing material is filled into the material frame 08, and then the material cover 09 is buckled. Then the material frame 08 can be inserted into the clamping ring 07, and the brewing material can be brewed when hot water is poured in. The material frame 08 can limit the brewing material and separate the brewing material from the obtained liquid, which is convenient for users to drink and prevents the brewing material, such as tea leaves, red dates and other substances, from being drunk into the mouth. At the same time, it is convenient to take away and fill, and can be used flexibly.

[0047] See attached Figures 1 to 12 From the structure shown, it can be understood that an exemplary use process of the present application for facilitating holding a cup is:

[0048] The outer wall of the cup body 01 is provided with a handle 13 which is perpendicular to the axis of the cup body 01 in a horizontal plane. The user can hold the plastic cup by holding the handle 13 with fingers, thereby preventing the user's fingers from touching the cup body 01, reducing the range of the fingers blocking the cup body 01, and facilitating moving the cup to the mouth for drinking.

[0049] See attached Figures 1 to 6 From the structure shown, it can be understood that an exemplary use process of the present application for easy storage is:

[0050] The outer wall of the cup body 01 is formed with a cavity 10 inwardly, and side grooves 11 are opened on the inner walls of both sides of the cavity 10. A slide post 12 is slidably contacted in the two side grooves 11. The inner end of the turning handle 13 is rotatably connected to the outer end of the slide post 12, and the lower side of the inner end of the turning handle 13 is formed with a retaining edge 14 that can be abutted against the lower side of the outer end of the slide post 12. When in use, the turning handle 13 can be rotated outwardly to make the retaining edge 14 on the lower side of the inner end of the turning handle 13 rotate to the tracking state and contact the lower side of the outer end of the slide post 12, so that when the turning handle 13 is lifted up, the slide post 12 can be kept horizontal and lifted together. At this time, the slide post 12 It can slide upward in the two side grooves 11 to the upper end, and then the cup body 01 can be driven up, and the turning handle 13 can be close to the upper end of the cup body 01, so that the user's hand is closer to the mouth when drinking, thereby improving the stability of the cup body 01, reducing the shaking of the cup body 01 when drinking, and making the cup body 01 more stable. After use, the slide column 12 can slide downward and reset by its own weight, and then the turning handle 13 can be rotated upward to fold the turning handle 13 into the concave cavity 10 for hidden storage, thereby reducing the scope of occupied space and facilitating the storage of plastic cups.

[0051] The manufacturing process of the plastic cup comprises the following steps:

[0052] S1: Use the mold to process the various parts of the plastic cup, and remove burrs and sharp edges by polishing;

[0053] S2: Rotate and connect the inner end of the turning handle 13 and the outer end of the sliding column 12 via a pin;

[0054] S3: Open two side grooves 11 on the inner walls of both sides of the cavity 10 and assemble the slide column 12, and rotate the handle 13 upward so that the handle 13 is folded into the cavity 10;

[0055] S4: bonding the vacuum ring 03 to the outer wall of the housing 01 by glue;

[0056] S5: Fasten the coaster 04 onto the cup brim 02 and use packaging film to package.
