[0002] Containers are items used for water or food, such as cups, bowls, plates, etc., which are widely used in daily life. Especially cups, people usually use cups to drink water, but ordinary cups have average thermal insulation performance, which causes the heat of water to dissipate quickly. Therefore, cups with thermal insulation layers have been invented on the market. In existing cups with thermal insulation layers, the connection strength between the thermal insulation layer and the cup is average. After long-term use, the thermal insulation layer may fall off, resulting in average product quality. Utility Model Content

The inner surface of the body is an irregular inner surface. The heat-insulating layer is attached to the inner surface of the body by spraying. Compared with the smooth inner wall, the irregular shape increases the contact area between the inner wall and the heat-insulating layer, thereby increasing the connection strength between the heat-insulating layer and the inner surface of the body, preventing the heat-insulating layer from falling off after long-term use, and ensuring the good production quality of the product.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-6 As shown, a container with a plastic-sprayed inner wall comprises a container body 1, wherein a heat-insulating layer 2 is arranged inside the body 1, which has a good heat-insulating effect. The inner surface of the body 1 is an irregular inner surface, and the heat-insulating layer 2 is attached to the inner surface of the body 1 by means of plastic-spraying. Compared with the traditional smooth inner surface, the irregular inner surface has an irregular shape that increases the contact area between the inner surface of the body 1 and the heat-insulating layer 2, thereby increasing the connection strength between the heat-insulating layer 2 and the inner surface of the body 1, preventing the heat-insulating layer 2 from falling off after long-term use, and ensuring good production quality of the product.
[0025] Spray molding is a process in which a high-voltage electrostatic device is charged and the paint is sprayed onto the surface of the workpiece under the action of the electric field. The powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating.
[0026] like Figure 2-4 As shown, the irregular inner surface of the body 1 includes a matrix distribution, a stripe distribution, and a honeycomb distribution.
[0027] Embodiment 1, as Figure 2 As shown, the irregular inner surface of the body 1 is distributed in a matrix shape, and the inner surface of the body 1 is provided with connecting parts 3, and the connecting parts 3 are distributed horizontally or vertically to form a matrix shape.
[0028] Embodiment 2, as Figure 3 As shown, the irregular inner surface of the body 1 is distributed in stripes, and a connecting portion 3 is provided on the inner surface of the body 1. The connecting portion 3 extends obliquely from the upper end of the inner surface of the body 1 to the lower end to form a stripe distribution.
[0029] Embodiment three, as Figure 4 As shown, the irregular inner surface of the body 1 is distributed in a honeycomb shape, and a connecting portion 3 is provided on the inner surface of the body 1, and a plurality of connecting portions 3 are distributed in a honeycomb shape.
[0030] The connecting portion 3 is integrally formed on the inner surface of the body 1, and an inner concave portion 4 is provided on the connecting portion 3, and the inner concave portion 4 includes a trapezoidal inner concave portion and an arc-shaped inner portion. An inclined surface 5 is provided on both sides of the inner concave portion 4. During the process of spray molding of the thermal insulation layer 2, the thermal insulation layer 2 will be embedded in the groove 5, which increases the contact area between the thermal insulation layer 2 and the body 1, and prevents the thermal insulation layer 2 from falling off after long-term use. Compared with the flat surface, the design of the inclined surfaces 5 on both sides further increases the contact area between the connecting portion 3 and the thermal insulation layer 2, further increases the connection strength, and the thermal insulation layer 2 is not easy to fall off.
[0031] The body 1 shown includes a water cup, a thermos cup, and a dinner plate, but is not limited to a water cup, a thermos cup, and a dinner plate. When the body 1 is a water cup, the insulation layer 2 is attached to the inner wall of the body 1; when the body 1 is a thermos cup, the insulation layer 2 is located in the vacuum layer, or the insulation layer 2 can also be attached to the inner wall of the body 1.
[0032] The insulation layer 2 shown includes a PPSU insulation layer, which has good heat resistance and toughness, and the specific heat capacity of the PPSU material is about 1.13 J / (g.°C), and the insulation performance is better.
[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
