Thus, the paper cup cover of the utility model has two kinds of assembling relations to form two kinds of paper cup covers, and the two kinds of paper cup covers have three kinds of usages, including an inner clamping type, an outer clamping type and an inner and outer clamping type.

In the above description, the orientations indicated by the "top end", "bottom end", etc. are described based on the orientation shown in fig. 1, and are only for convenience of description, and do not indicate or imply that the designated parts or elements must have a specific orientation. The paper cup cover body shown in fig. 3-4 and 6 is rotated 180 degrees relative to the paper cup cover body shown in fig. 1, the paper cone ring shown in fig. 7 is rotated 180 degrees relative to the paper cone ring shown in fig. 1, for the sake of description requirement and consistency of terms expressed, the top end and the bottom end of the first arc-shaped roll of the paper cup cover body shown in fig. 3-4 and 6 are still consistent with the top end and the bottom end of the first arc-shaped roll expressed based on fig. 1, and the top end and the bottom end of the second arc-shaped roll of the paper cone ring shown in fig. 7 are still consistent with the top end and the bottom end of the second arc-shaped roll expressed based on fig. 1.

On the other hand, as shown in fig. 8, the paper cover 2 is provided with a recessed area 3 having one lowest position, and the lowest position of the recessed area 3 is provided with a drinking hole 4 and a paper cover 5 for closing the drinking hole 4. Because the drinking hole 4 is arranged at the lowest position of the concave area 3, after a user drinks the drink, the liquid flowing out from the mouth seam of the user and flowing into the concave area 3 can flow back to the drinking hole 4 due to the inclined surface design of the concave area 3, so that the liquid can be prevented from remaining on the paper cover plate 2, and the integral cleanness of the paper cover is improved.

The recessed area 3 may be of conical configuration, but since the drinking aperture 4 is provided at the edge of the paper cover 2, and in order to increase the paper-covered covering area of the recessed area 3, it is preferable to provide the recessed area 3 with an irregular conical configuration. As shown in fig. 9, the inclined plane of depressed area 3 is the arcwall face, make the contact surface of depressed area 3 more laminate with last lip, increase the area of contact of paper apron 2 and last lip, the effect of preventing the edge leakage has, and avoided the problem of traditional planar contact surface extrusion upper lip, make the user be in just contacting but not extruded state between upper lip and the paper apron 2 in the process of drinking, make the paper apron 2 be in the lip contact structure of optimality, very big increase user's drinking experience.

As shown in fig. 14, the outer edge of the second curl 10 is provided with a folded edge 12 folded outwards, a certain included angle is formed between the folded edge 12 and the second curl 10, the contact surface between the second curl 10 and the paper cover 1 is changed from a parallel relationship to a cross relationship, so that the folded edge 12 abuts against the inner wall of the paper cover 1, the friction force between the second curl 10 and the inner wall of the paper cover 1 is increased, and the pressure of the first curl 9 for fixing the second curl 10 can be relieved.

As shown in FIGS. 5 and 6, the inner and outer snap-in type paper cup covers and the outer snap-in type paper cup cover preferably use recessed areas. More preferably, the outer clamping type cup cover uses a concave area.

Taking the out-clamping type cup cover as an example, as shown in fig. 15 and 16, in one specific embodiment, the linear crease 6 is a half chord of the paper cover plate; the shape and size of the drinking hole 4 are matched with the paper cover plate 5, one side of the paper cover plate 5 is integrally connected with the paper cover plate 2, and a crease 52 is arranged at the joint of one side of the paper cover plate 5 and the paper cover plate 2; the other side of the paper cover 5 can be buckled on the first rolling edge 9 and also can be lifted from the first rolling edge 9. The paper flap 5 may snap onto the first flange 9 when the drinking aperture is opened, or may snap into the first flange 9 when the drinking aperture is closed. The paper cover plate 5 has an elastic effect, so that the paper cover plate can be directly buckled on the first curling edge and then can be directly lifted from the first curling edge 9, and thus, a clamping structure used for the paper cover plate is omitted, and the first curling edge is skillfully utilized as a clamping structure.

The first beads 9 of fig. 10-11, 15-16 are only schematically indicated by lines. The specific structure of which can be seen more clearly in fig. 12-14.

The above detailed description is only for the purpose of illustrating the practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the technical spirit of the present invention are intended to be included within the scope of the present invention.
