Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: the cup body and the outer cup wall are only integrated through socketing, and in the process of transfer, transportation and use, it is easy to loosen, and even cause the cup body to separate from the outer cup wall. Detach from the middle, affect the grip of the hand, and increase the chance of liquid spilling in the paper cup

Embodiment 1

[0049] refer to figure 1 , which is a paper cup disclosed by the present invention, comprising an inner core and an outer casing 8 both in the shape of a truncated cone, and the outer casing 8 is sleeved on the outer peripheral side wall of the inner core. The inner core includes a cup body 2 and a cup bottom 3. The upper end surface of the inner core is open and rolled outward to form a roll opening 5. The diameter of the upper end surface of the inner core is larger than the diameter of the lower end surface.

[0050] refer to figure 2 and image 3 Both ends of the outer casing 8 are provided with openings, and the lower end face of the outer casing 8 is rolled inward to form a roll bottom 4. The diameter of the roll bottom 4 is larger than the diameter of the lower end face of the inner core but smaller than the diameter of the upper end face of the inner core.

[0051] refer to image 3 and Figure 4 , the inner wall of the outer casing 8 is embossed with embossing 7 ...

Embodiment 2

[0055]A process for making a paper cup disclosed in the present invention is used to produce the paper cup disclosed in the first embodiment, including: making an inner core, making an outer jacket 8, and gluing the paper cup.

[0056] Among them, refer to figure 1 and image 3 , the steps for making the inner core are as follows:

[0057] S1, one side of the base paper is coated with PE film with a laminating machine to form raw paper, and the raw paper is cut to form a small rectangular sheet for making the cup bottom 3 and a large rectangular sheet for making the cup body 2.

[0058] S2, use a die-cutting machine for die-cutting in the large rectangular sheet, and die-cut a plurality of inner fan ring sheets for making the cup body 2 .

[0059] S3, embossing an arc-shaped concave groove 1 on the side of the inner fan ring sheet away from the PE film, the radian of the groove 1 is the same as that of the arc edge of the inner fan ring sheet, and the groove 1 is close to th...

Abstract

The invention discloses a manufacturing process of a paper cup, and relates to the technical field of environmental protection packaging. The method comprises the following steps of manufacturing an inner core, making an outer sleeve and adhering the paper cup. Concave grains are firstly pressed on the inner core before a paper cup forming machine is used for forming; the outer sleeve is firstly rolled at bottom before the paper cup forming machine is used for forming; and the roll bottom is clamped into the concave grains during bonding, and glue is matched for coating, so that the inner core and the outer sleeve are more tightly and firmly combined, due to the roll bottom, a certain distance is reserved between the inner core and the outer sleeve, the heat transfer is hindered, and holding is more stable by human hands.

Description

technical field [0001] The invention relates to the technical field of environmental protection packaging, in particular to a manufacturing process of a paper cup. Background technique [0002] The paper cup is a kind of paper container made by mechanical processing and bonding of the base paper (white cardboard) made of chemical wood pulp. It can hold or pack different items, and can even bloom water. It is safe, hygienic, light and convenient, easy to recycle and reuse, green and environmentally friendly, and can reduce environmental pollution. [0003] However, due to the limited thickness of paper cups, it is not easy to add a hard handle. When holding hot water, people's hands are easily scalded and should not be taken. Therefore, many multi-layer paper cups have appeared, and multi-layer paper cups usually include mutually bonded inner cores. With the outer layer, the outermost layer of the outer layer is pressed with uneven lines and then wrapped around the circumfer...
