Abstract
Description
Technical Field
[0001] The utility model relates to an integrated double-layer cup with inside painting, specifically belonging to the technical field of inside-painted water cups. Background Art
[0002] At present, for the double-layer glass containers with inside-painting technology on the market, since the inside-painting is directly formed on the inner surface of the outer container, a cavity is formed between the double layers of glass. This structure can keep the inside-painting on the inner surface of the container intact, with the inside-painting being clear, intuitive, and increasing the artistic value of the container. However, it has the following deficiencies: Due to the conflict between the processing of the double-layer glass container and the formation of the inside-painting technology, after the inside-painting is formed on the inner surface of the container, the high-temperature firing process often damages the painting, resulting in a distorted image. Therefore, to manufacture a double-layer glass cup, high-temperature annealing is required to ensure that the cup body can withstand thermal changes, and at the same time, damage to the painting caused by high temperature should be avoided. In the prior art, generally two methods are used to solve this problem: One is that the painting is formed on the middle-layer glass container located between the inner and outer glass cups, avoiding damage to the painting during high-temperature firing, and the middle layer is adhesively bonded between the inner and outer glass cups through a bottom opening; the other is that the painting is formed on the surface near the bottom of the outer glass cup, avoiding the painting being too close to the firing position and damaging the painting, and the bottom of the outer layer is adhesively bonded later. However, for the double-layer glass cups manufactured in the above forms, the connection between the inner and outer layers is not firm, and the inner and outer layer structures are bulky, with limited painting positions, affecting the aesthetics. Summary of the Invention
[0003] The purpose of the utility model is to provide an integrated double-layer cup with inside painting, on which patterns are drawn by inside-painting technology on the outer periphery and / or the inner surface of the bottom of the outer cup facing the inner cup. Since the double-layer cup is integrally formed, it has a light and firm structure, and the painting is protected by local heating during the forming process, taking into account both the ornamental and the use effects, and having high artistic and commercial values.
[0004] To achieve the above object, the present utility model is realized through the following technical solutions: An integrated inner-painted double-layer cup, the material of the integrated inner-painted double-layer cup is glass, including an inner cup and an outer cup, characterized in that the inner cup includes an integrally formed first outer periphery and a first bottom; the outer cup is a cup body with a curved belly and a small mouth or an inverted trapezoidal cup body, and the outer cup includes an integrally formed second outer periphery and a second bottom; a whole cavity is formed between the first outer periphery and the first bottom of the inner cup and the second outer periphery and the second bottom of the outer cup, and a pattern is drawn on the inner surface of the second outer periphery and / or the second bottom of the outer cup facing the inner cup side by the inner-painting process; the inner cup and the outer cup are formed into an integral structure at the cup mouth through a glass fusion process, and at the cup mouth, the inner cup and the outer cup are flush and jointly form a smooth edge, and the edge is the cup mouth edge of the integrated inner-painted double-layer cup; during the fusion process, high-temperature protection is carried out on the inner-painted pattern, so that the distance between the highest position of the inner-painted pattern and the cup mouth edge is ≤5 cm.
[0005] Further, the material of the integrated inner-painted double-layer cup is transparent glass or colored glass.
[0006] Further, the cross-sectional shape of the outer cup is U-shaped or V-shaped.
[0007] Further, the bottom shape of the inner cup is one of a geometric shape, a mountain shape, a flower shape, a leaf shape, an animal shape, and a claw shape.
[0008] Further, a handle for easy holding is welded on the second outer periphery side of the outer cup, and the number of handles is one or more.
[0009] Further, feet are welded on the bottom surface of the second bottom of the outer cup, and the number of feet is one or more.
[0010] The advantages of the present utility model are as follows: Through the integrally formed inner-painted double-layer cup, since both the glass inner cup and the glass outer cup have undergone high-temperature annealing treatment before the inner-painting process is carried out, it has good performance in resisting instantaneous changes in cold and heat; after the inner-painting process is completed, the inner cup and the outer cup only need to be formed into an integral structure at the cup mouth through a glass fusion process. Since only the cup mouth is welded, local high-temperature annealing treatment is carried out, and high-temperature protection is carried out on the inner-painted pattern during welding, which not only improves the structural firmness of the double-layer cup, but also ensures that the inner-painted pattern is complete and the color is bright, and can realize that the distance between the highest position of the inner-painted pattern and the cup mouth edge is ≤5 cm. The outer cup is set as a cup body with a curved belly and a small mouth or an inverted trapezoidal cup body, which expands the use functions of making coffee, milk, etc. compared with the existing all-cylindrical inner-painted double-layer cups that are only used as business cups for making tea.
