Embodiment 1

[0028] see Figure 1 to Figure 4 As shown, a paper cup lid includes a hollow paper lid body 1 and a circular paper lid plate 2, the top and bottom ends of the paper lid body 1 are circular, and the paper lid body 2 is generally or roughly in the shape of a truncated cone , the circular edge at the bottom end is rolled up from bottom to top to form an arc-shaped roll, and the upper end of the arc-shaped roll is flattened to form a flat ring-shaped connecting surface 3, which is connected to the paper cover plate 2 Flat edges are press-fitted in place. The rounded edge at the top can also be rolled up in an arc from top to bottom to form another arc roll.

[0029] The paper cover plate 2 of this embodiment may only be a single layer.

[0030] The paper cover 2 of the present embodiment is provided with a drinking port 3, and the shape and size of the drinking port 3 are all matched with a cover 4, and one side of the cover 4 is integrally connected with the paper cover 2; One...

Embodiment 2

[0039] Referring to Embodiment 1, on the basis of Embodiment 1, the arc-shaped roll at the lower end is flattened to form another planar ring-shaped connecting surface 7 . Flattening the upper and lower sides is more convenient for mold processing.

Embodiment 3

[0041] As a preferred embodiment, the circular edge at the top of the paper cover body is rolled up in an arc shape from top to bottom to form another arc roll, thereby forming a high-quality paper cup cover. The other arc-shaped roll can reduce the thickness of the single-layer paper material for curling, and can increase the strength by more than 1 time.

[0042] It should be noted that in the description of the present invention, the orientations indicated by the terms "top", "bottom", "upper", and lower are based on the attached Figure 1-2 The descriptions of the orientations shown are only for the convenience of description, but do not indicate or imply that the components or elements referred to must have specific orientations, and thus should not be construed as limiting the present invention. when attached Figure 1-2 When the position of is rotated by 180°, its corresponding orientation term also changes adaptively, which should not affect the scope of protection of...

Abstract

The invention discloses a paper cup cover and a preparation method thereof. The paper cup cover comprises a hollow paper cover body and a circular paper cover plate; the circular edge, which is positioned at the bottom end, of the paper cover plate is rolled up inwards from the bottom to the top to form an arc-shaped roll; the upper end of the arc-shaped roll is flatted to form a planar annular connecting surface; and the connecting surface and the plane edge of the paper cover plate are pressed and fixed. The preparation method comprises the steps of performing rolling, flattening, pressing and fixing correspondingly. The paper cup cover disclosed by the invention has sealing property and fastness; and moreover, paper can be reduced greatly, and glue is not used, so that the paper cup cover is very environment-friendly.

Description

technical field [0001] The invention relates to the technical field of cup lids, in particular to a paper cup lid and a preparation method thereof. Background technique [0002] At present, there is a paper cup cover, which includes a hollow paper cover body and a circular paper cover plate. The circular edge of the paper cover body at the bottom end is rolled up in an arc shape from bottom to top to form an arc roll, and the paper cover plate is bonded. There is a thin paper wrapped around and glued on the arc-shaped roll. [0003] The paper cup cover needs to use thin paper as an intermediate connecting part to connect the paper cover body and the paper cover plate, and needs to be fixed with glue. Glue is a chemical, which is easy to have a bad effect on drinks; and each paper cup lid must use a thin paper, and the amount of thin paper is also large. [0004] It should be noted that the present invention is innovative based on the aforementioned paper cup lid. However,...
