Problems solved by technology

[0003] Furthermore, since paper cups hold water for a long time, they are easy to become soft and deformed. Although a curved strip is formed on the top edge of the paper cup, the strength is actually insufficient.

Embodiment Construction

[0040] The present invention relates to a method for making a paper container and its products. The flow chart is described below with reference to the drawings.

[0041] a. Spare materials: please refer to figure 1 , 2 As shown, in the process of preparing materials, the plain paper roll (10) is passed through the coating machine (11), and the surface of the plain paper roll (10) is covered with a waterproof film (201) to form a coated paper (20), providing the plain paper roll (10) with water resistance through the waterproof membrane (201).

[0042] b. Cutting: please cooperate figure 1 , 3 As shown, the coated paper (20) is automatically cut into the coated paper (21) of the set size by the cutting machine (12), and the coated paper (21) is passed through the printing machine (13) Patterns such as printed pictures, texts or trademarks on the coated paper sheet (21), then enter the die-cutting machine (14) to be cut into the die-cut paper sheet (22) that the container i...

Abstract

The invention discloses a method for manufacturing a paper container and products thereof. The method mainly comprises the step of: after the flow of material preparation, trimming and coiling, molding a coiled conical paper tube into the paper container through mould entering, and mould closing and material injection, wherein the conical paper tube is provided with two axial grooves at the left and right sides thereof, and the conical paper tube is placed into a lower mould of a mould, first and second sprue channels are formed on an upper mould, and a substrate corresponding to the bottom of the container and the conical paper tube are sequentially placed into the lower mould; and then the upper mould is closed to the lower mould, and the plastic injected into the first and second sprue channels under low pressure are filled at the periphery of the top of an opening of the conical paper tube and on an adjoining plane between the substrate and the conical paper tube, thereby forming the paper container different from paper containers made of all paper materials before.

Description

technical field [0001] The invention relates to a technical field related to packaging containers, in particular to a method for making paper containers such as paper cups, paper bowls, and paper plates from paper materials and the products thereof. Background technique [0002] According to the method of making paper cups made of paper, the coated paper is rolled and bent into a cylindrical cup surface, and the left and right sides are pasted and joined, while the negative section at the bottom of the paper cup is in an inverted U shape. Adhesive bonding of cup noodles. However, this method will bend the top edge of the paper cup into strips to increase the shaping strength, and the back sheet must be inverted U-shaped to bond with the cup surface, so more paper is consumed, and the accumulated number of paper cups , it seems that the consumption of paper materials is constantly rising. Under the pressure of rising raw materials, how to effectively reduce paper materials i...
