Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1, it is a schematic structural diagram of a paper cover with high stiffness according to a first embodiment of the present invention. The paper cover having high stiffness is used to cover one container 20. The container 20 comprises a container mouth 21 and a bead 22 arranged on the edge of the container mouth 21. The paper cover with high stiffness comprises a cover body 10, a reinforcing edge 12 arranged on the cover body 10, a curled edge containing groove 13 arranged on the reinforcing edge 12, and a lead-in part 14 connected with the curled edge containing groove 13. The paper cover having high stiffness may be made of food paper, and the cover body 10 or the reinforcing rim 12 may be made of food paper having a grammage of 190 g to 380 g.
The cover 10 includes a cover bottom 101, and a cover rim 102 disposed at an edge of the cover bottom 101 and extending toward a side of the cover bottom 101. The cross section of the cover bottom 101 along the central axis perpendicular to the cover bottom 101 may be any shape such as a circle, a square, a polygon, etc., and it may be designed according to actual requirements, that is, the shape of the container mouth 21 of the container 20. In the embodiment, the cover bottom 101 may be circular along a cross section perpendicular to the central axis of the cover bottom 101 only for explaining the structure and the operation principle of the present invention. The lid rim 102 extends from the edge of the lid base 101. In order to facilitate the cover 101 to be fastened to the container 20, an included angle between the extending direction of the cover rim 102 and the central axis of the cover bottom 101 is an acute angle.
The reinforcing rim 12 is of a U-shaped configuration and wraps around three outer sidewalls of the lid flange 102. The reinforcing flange 12 is provided on the lid flange 102 by means of an adhesive.
The curl receiving groove 13 is disposed at the lid rim 102 by pressing, and specifically, the curl receiving groove 13 is pressed on the structure formed by the reinforcing rim 12 and the lid rim 102, that is, the curl receiving groove 13 is integrally formed on the reinforcing rim 12 and the lid rim 102. The bead accommodating groove 13 is formed in an arc shape in a cross section along the center axis of the lid bottom 101, and the central angle of the arc shape is less than 180 degrees, so that the bead 22 provided on the container mouth 21 can be smoothly inserted into the bead accommodating groove 13.
The lead-in portion 14 is disposed on the opposite side of the curl receiving groove 13 with respect to the lid rim 102, that is, the curl receiving groove 13 is disposed between the lid rim 102 and the lead-in portion 14, which also makes the lead-in portion 14, the curl receiving groove 13, and the lid rim 102 integrally formed. The introduction portion 14 serves as a guide when the paper lid is engaged with the container mouth 21 of the container 20. The direction of extension of the lead-in 14 may be parallel to the direction of extension of the lid rim 102. In addition, an angle between the extending direction of the introduction portion 14 and the central axis of the cover bottom 101 may be larger than an angle between the extending direction of the cover rim 102 and the central axis of the cover bottom 101. In this embodiment, the extending direction of the introducing portion 14 may be parallel to the extending direction of the cover rim 102.
As shown in fig. 2, the paper cover with high stiffness provided by the first embodiment may further include a stop flange 15. The stop flange 15 is disposed on the reinforcing rim 12 opposite to the lid edge 102 of the lid body 10 and between the curl receiving groove 13 and the lid bottom 101. The stop flange 15 protrudes in the direction of the central axis of the cover bottom 101. When the paper cover is covered on the container opening 21, the stop flange 15 is used for preventing the container opening 21 from sliding out of the curled edge containing groove 13 and abutting against the cover bottom 101 of the cover body 10, so that the phenomenon of incapability of sealing or liquid leakage is caused. The stop flange 15 may be in the form of a separate ring which is bonded to the opposite reinforcing rim 12 of the lid flange 102. The stop flange 15 may also be formed by direct pressing of the reinforcing flange 12 and the lid flange 102. In this embodiment, the stop flange 15 is directly pressed from the reinforcing rim 12 and the lid rim 102, and the stop flange 15 is directly connected to the curl receiving groove 13.

Preferably, the reinforcing rib 16 is located at the edge of the cover bottom 101. The reinforcing rib 16 may have a V-shape or a groove shape in a cross section along the central axis of the cover bottom 101. When the reinforcing bead 16 has a groove shape, the groove shape may be one of a square shape, a U shape, or a circular arc shape. In this embodiment, the reinforcing rib 16 has a V-shape in a cross section along the center axis of the cover bottom 101. During production, the V-shaped or groove-shaped reinforcing rib 16 can be directly pressed out of the lid bottom 101 using a die. The reinforcing ribs 16 can improve the strength of the lid bottom 101, so that the lid bottom 101 is not easily deformed when the lid bottom is used, for example, when the lid bottom is held by hand. Another advantage is that when the paper cover is placed on a carrying surface such as a table and the cover bottom 101 contacts the carrying surface, the ribs 16 will preferentially contact the carrying surface, thereby changing the contact of the paper cover with the carrying surface from surface contact to line contact, thereby making the placement of the paper cover more stable.
As shown in fig. 4, the paper cover having high stiffness provided by the first embodiment may further include a suction nozzle 17. The straw opening 17 is arranged on the cover bottom 101 of the cover body 10, and can be one of a cross-shaped notch, a circular through hole and a hexagonal through hole. It is of course conceivable that the nozzle 17 may have other configurations, which may be set according to actual needs. The straw opening 17 is used for inserting a straw through which the liquid in the container 20 is sucked.
Compared with the prior art, the utility model provides a paper lid with high deflection is directed at container 20's turn-up 22 has designed the paper lid that has turn-up storage tank 13. Since the curl receiving groove 13 protrudes in a direction away from the central axis of the lid bottom 101, when the paper lid is fastened to the container, the curl receiving groove 13 is covered on the curl 22 of the container 20. Meanwhile, the paper cover is made of paper, such as food-grade paper, in order to keep the stiffness of the paper cover, the cover edge of the paper cover is provided with the reinforcing edges 14, and the reinforcing edges 14 are coated on the three outer side walls of the cover edge, so that the stiffness of the paper cover is kept, the strength of the paper cover is guaranteed, the paper cover is prevented from deforming when being buckled on a container, and the paper cover cannot deform when being held by a user, namely, the paper cover has high stiffness. The curled edge containing groove 13 and the cover bottom 101 are arranged at intervals, so that the curled edge containing groove 13 can be manufactured conveniently, and the paper cover with high stiffness has manufacturing feasibility.
