DETAILED DESCRIPTION

The present application is illustrated by way of example and not by way of limitaion in the figures of the accompanying drawings. It should be noted that references to “an” or “one” embodiment in this application arenot necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1 to FIG. 6, an abutting-typed paper cover is shown in accordance with an examplary emobodiment of the present invention. The abutting-typed paper cover is used to cover a container 20. The container 20 includes a container opening 21, and a curling rim 22 arranged on the container opening 21. The abutting-typed paper cover includes a cover body 11, a reinforced guide portion 11 provided on the cover body 10, and a buckling portion 12 extending from the reinforced guide portion 11. The abutting-typed paper cover can be made of food paper, and the cover body 10, the reinforced guide portion 11 and the buckling portion 12 can all be made of food paper with a weight of 70 to 600 grams. The food paper can be double-sided PE coated paper or single-sided PE coated paper.
The cover body 10 includes a flat face 101, and a cover rim 102 arranged on the flat face 101 and extending towards a side of the flat face 101. The cross secion of the flat face 101 taken along the vertical line perpendicular to the plane where the flat face 101 is located may be any shape, such as a circle, a square, a polygon, and so on, which can be designed according to actual needs. In the present embodiment, only for explaining the structure and working principle of the present invention, the flat face 101 has a shape of circle. The cover rim 102 extends from an edge of the flat face 101, and an angle between the extending direction of the cover rim 102 and the vertical line perpendicular to the plane where the flat face 101 is located is an acute angle, and the acute angle is 0 to 15 degrees. Specifically, the acute angle between the extending direction of the cover rim 102 and the vertical line of the plane where the flat face 101 is located is 0 degree. The flat face 101 and the cover rim 102 are integrally formed. In the direction along the vertical line of the plane where the flat face 101 is located, the height of the cover rim 102 is between 2 mm and 20 mm to facilitate aesthetics.
The reinforced guide portion 11 is provided on the cover rim 102 and wraps on the three outer side walls of the cover rim 102. Therefore, the reinforced diversion portion 11 has a cross section of a groove-shaped structure taken along the vertical line of the plane where the cover surface 101 is located. The reinforce guide portion 11 may be adhered to the cover rim 102 by food grade glue. The reinforced guide portion 11 can not only be used for sealing a free edge of the cover rim 102, but also can improve the strength and stiffness of the cover rim 102. If without the reinforced guide portion 11, the free edge of the cover rim 102 will be exposed to the outside, which is not conductive to aesthetics. Moreover, since the free edge of the cover rim 102 will be the part that can be directly taken by the user's hand, the cover rim 102 need more strength and stiffness. The reinforced guide portion 11 will help to improve the strength and stiffness of the cover rim 102 so that the cover rim 102 will not be crushed when taken. If the cover rim 102 is crushed when in use, it will affect the user experience.
The buckling portion 12 extends from the reinforcing guide portion 11, and the extending direction of the buckling portion 12 is opposite to the extending direction of the cover rim 102. Specifically, the buckling portion 12 is integrally formed with one side of the reinforced guide portion 11 which has the groove-shaped structure. In the prior art, a cover rim bent form the cover body is directly buckled on a container. Due to physical limitains, when a whole piece of paper is bent out of the cover rim, multiple wrinkles must be formed at the joint of the cover rim and the cover body. When the cover with the wrinkles is abuckled on the container, the liquid in the container will inevitabley leak out from the wrinkles, which causing a bad user experience. In the present embodiment, the cover rim 102 of the cover body 10 is used to improve the strength and stiffness of the entire paper cover, and the buckling portion 12 is used to buckle with the container 20. Since the buckle portion 12 is not in the bending process, there will be no wrinkles so that there will be no leakage or seepage during use. On a section taken along the vertical line which is perpendicular to the plane where the flat face 101 is located, the buckling portion 12 includes an arc-shaped section 121, an push-stop section 122 connected to the arc-shaped section 121, and an push-stop curling rim 123 arranged at the free end of the push-stop section 122. One end of the arc-shaped section 121 is connected to the flat face 101. As a result, when the abutting-typed paper cover is buckled on the curling rim 22 of the container 20, a side part of the curling rim 22 abuts against the arc-shaped section 121 and a top part of the curling rim 22 abuts against the flat face 101. Because of the arc-shaped section 121, it will prevent the curling rim 22 of the container 20 from slipping off the arc-shaped section 121. The angle between the chord of the arc-shaped section 121 and which is perpendicular to the plane where the flat face 101 is located is an acute angle, and the acute angle is between 0 degrees and 30 degrees. A central angle of the arc-shaped section 121 is less than or equal to 180 degrees so as to easy to insert into the curling rim 22 of the container 20. An angle between the extending direction of the push-stop section 122 and the vertical line of the flat face 101 is an acute angle, and the acute angle is between 0 degree and 15 degrees. In order to make it easier for the curling rim 22 of the container to insert into the arc-shaped section 121, the push-stop section 122 further includes a transition section 1221. The transition section 1221 is connected to the arc-shaped section 121. The transition section 1221 is arc-shaped, and the curvature direction of the transition section 1221 is opposite to that of the arc-shaped section 121. The push-stop curling rim 123 is provided on the free end of the push-stop section 122, and its structure should be the prior art. The function of the push-stop curling rim 123 is not only to hide the edge of the push-stop section 122, but also to be beautiful. Because of the push-stop curling rim 123, it makes it easier to buckle in the container 20 and the buckling portion 12 has better stiffness and is not easy to be crushed. The shape of the push-stop curling rim 123 may be a circle, a polygon, or the like. The height of the abutting-typed paper cover is between 10 mm and 60 mm.
The abutting-typed paper cover further includes a sucker hole 13 provided on the flat face 101. The sucker hole 13 may be a through hole, or at least three punching covers may be provided on the through hole so as to cover the through hole. Understandable, in order to make the punching cover easy to be folded and not torn from the flat face 101, the joints between at least three punching cover and the sucker hole 13 are provided creases. In the present embodiment, the sucker hole 13 include a through hole 131, and six punching covers 132 covered on the through hole 131. The joints between each of the punching cover 132 and the through hole 131 has a crease 133.
Moreover, the abutting-typed paper cover further includes a direct drinking hole 14. The direct drinking hole 14 is a through hole, and the through hole may be polygonal, circular, or elliptical. The Polygon hole can be quadrilaterals, hexagons, etc. The direct drinking hole 14 further includes a hole cover covered thereon, and a connection provided between the cover and the through hole. A crease is disposed on the connection so as to facilitate the opening of the cover and not to tear the flat face 101 when it is opened.
As described above, the abutting-typed paper cover is made of paper, which meets the requirements of environmetal protection. Moreover, the abuttig-type paper cover has the cover body 10,and the cover body 10 has the cover rim 102. Therefore, when the reinforced guide portion 11 is disposed on the cover rim 102, the strength of the abutting-typed paper cover can be ensured, so that the abutting-typed paper cover has a high stiffness. As a result, when user uses the abutting-typed paper cover, it will not be easily crushed. Since the buckling portion 12 extends from the reinforced guide portion 11, and the extending direction of the buckling portion 12 is opposite to that of the cover rim 102, no wrinkles are formed during the bending process. Therefore, when the buckling portion 12 is buckled on the curling rim 22 of the container 20, no leakage will occur, and the sealling property is ensured. The buckling portion 12 is provided with the arc-shaped section 121, and one end of the arc-shaped section 121 abuts on the flat cover 101, so that when the abutting-typed paper cover is buckled on the container 20, the cover rim 22 abuts on the arc-shaped section 121 and the flat face 101. Therefore, the abutting-typed paper cover can be fixed on the container 20 and it will not fall off without external force, and it can form a better seal with the container so that the liquid in the container will not leak out.
While the disclosure has been described by way of example and in terms of exemplary embodiment, it is to be understood that the disclosures is not limited thereto. To the contrary, it is intended to lamp shade various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
