Problems solved by technology

[0003] For example, the invention patent with the authorized notification number CN202269795U discloses a goblet, and discloses the following technical characteristics, a kind of goblet includes a base and a cup body arranged on the base, and the cup body is provided with The support rod is hollow and communicated with the cup body. The bottom end of the support rod is sealed. The upwardly protruding part of the base is provided with an inwardly recessed cavity. The size of the cavity corresponds to the size of the bottom of the support rod. The cup body passes through The bottom of the pole is inserted into the cavity on the base and is flexibly connected to the base. In this goblet, although the pole is hollow, it reduces the use of materials and reduces the cost, but there are the following technical problems at the same time. 1. The cup body Mostly made of a layer of plastic material, the strength is low, and it is prone to dents during use, resulting in inconvenient use and even spilling food. Its thickness is small, it is easy to transfer heat, and it is easy to cause scald accidents during use; 2. In order to control cost, the material and processing method of existing disposable tableware are almost simple and rough, and the quality and hygiene of the tableware cannot be guaranteed; 3. Since the same cup body uses the same material, the inside and outside of these cups The two surfaces are usually the same color, and the same color causes the color of the cup body to be too single, which is difficult to attract customers to buy, and as a decoration or decoration, its decorative effect is also poor

Abstract

The invention relates to a double-color plastic cup and a processing method thereof, and belongs to the technical field of cup processing. The cup comprises a cup body. A base is arranged at the bottom of the cup body and connected with the cup body through a supporting rod. The cup body is formed by multiple layers of sheets in a laminated mode, the sheets are tightly attached to one another, and the sheets on the inner and outer surfaces of the cup body have different colors. The supporting rod is fixedly connected with the sheet on the outer layer of the cup body. The sheets are made of polypropylene plastic (PP) or polystyrene plastic. According to the processing method of the cup, different kinds of color powder are added into the plastic raw material to manufacture the sheets of different colors, the sheets are laminated, and an injection moulding process is adopted for obtaining the cup body with the outer surface layer connected with the supporting rod; an installation column at the bottom of the supporting rod is inserted into an installation hole in the base, and then the double-color plastic cup can be obtained. Because the cup body of the cup is formed by the multiple layers of sheets in a combined mode, the cup has high strength without becoming sunk easily, and is convenient to use and novel in appearance; because injection moulding is adopted, the processing method of the cup is easy and convenient to implement.

Description

technical field [0001] The invention belongs to the technical field of cup processing, and relates to a two-color plastic cup and a processing method thereof. Background technique [0002] In daily life, cups refer to various cups for drinking water.
