[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0023] Example 1:

[0024] In this embodiment, if Figure 1-4 As shown, the utility model proposes an anti-detachment and anti-extravasation paper cover, comprising a top cover 1, a paper ring 2 and an inner cover 3, the upper part of the paper ring is bent inward to form a curling edge 21, the edge of the top cover is bent upward to form a folded corner 11, the vertical surface of the folded corner is a folded edge 12, the folded edge is inserted between the upper inner wall of the paper ring and the outer wall of the curling end, and the two sides of the folded edge are respectively abutted against the upper inner wall of the paper ring and the outer wall of the curling end, the paper ring and the top cover form an open cavity, the inner cover is stuck in the cavity, the top cover is provided with a first through hole 13, the inner cover is provided with a second through hole 31, and the bottom surface of the inner cover is provided with a pre-pressing hole 32, the pre-pressing hole only has an indentation and is not a through hole.

[0025] In this example, the paper cover is buckled with the paper tube containing hot porridge. When the amount of steam is large, that is, when the temperature of the food in the paper tube is high, the steam rises upward to form a bulge in the pre-pressed hole, and the gap between the top cover and the inner cover is enlarged. The steam is dissipated along the second through hole and the first through hole, which keeps the food warm while having a certain degree of air permeability. Moreover, since the paper cover is air permeable, the paper cover and the matching paper tube can be put into a microwave oven together for short-time heating, which is convenient for heating and eating.

[0026] In this example, the upper portion of the paper ring is bent inward to form a curled edge using a curling device. During the curling process, the upper portion of the paper ring is folded inward so that there are multiple creases on the inner side of the curled edge. This is a normal phenomenon. The curling device is a prior art. The edge of the top cover is bent upward to form a folded corner using a pressing device. During the pressing process, there are multiple creases at the folded corner of the top cover. This is a normal phenomenon. The pressing device is a prior art.

[0027] In the present embodiment, it is further configured that the aperture of the first through hole is consistent with the aperture of the second through hole, the first through hole and the second through hole do not overlap, the paper cover and the paper tube are buckled, when the amount of steam is small, the pre-pressure hole does not form a bulge, the gap between the top cover and the inner cover is small, and the steam is not easy to pass through. The design that the first through hole and the second through hole do not overlap can better insulate the paper tube.

[0028] In this embodiment, it is further configured that the diameter of the pre-stressing hole is larger than the diameter of the second through hole, the pre-stressing hole and the second through hole do not overlap, and the pre-stressing hole does not affect the air permeability of the second through hole.

[0029] In this embodiment, it is further configured that the diameter of the inner cover is slightly larger than the diameter of the paper ring. When the inner cover is assembled, the inner cover is directly pressed into the open cavity surrounded by the paper ring and the top cover to engage. Since the diameter of the inner cover is slightly larger than the diameter of the paper ring, the inner cover will not fall off, and the inner cover can rotate in the open cavity.

[0030] In this embodiment, it is further configured that the paper ring, the top cover and the inner cover form a breathable cavity 4.

[0031] In this embodiment, it is further configured that the bottom surface of the inner cover is heat-sealed and covered with a laminated paper 5, which is waterproof and oil-proof to prevent the inner cover and the top cover from being soaked, damaged or leaked.

[0032] Example 2:

[0033] In this embodiment, if Figure 4 As shown, a groove 22 is provided on the lower outer wall of the paper ring, and a convex groove 23 is provided on the lower inner wall of the paper ring. The convex groove of the paper ring can be tightly buckled with the outer curled paper tube to prevent the paper cover from falling off and prevent the porridge in the paper tube from leaking and spilling.

[0034] The production process of the anti-detachment and anti-extravasation paper cover is as follows: the top cover is placed on the upper part of the paper ring by a positioning device, and the top cover is pressed into the inside of the paper ring by a pressing block. At this time, the edge of the top cover is bent upward to form a folded angle, and the vertical surface of the folded angle is a folded edge, which is fitted with the inner wall of the upper part of the paper ring. The upper part of the paper ring is bent inwardly to form a curled edge by a curling device, and heat treatment is performed to make the outer wall of the end of the curled edge fit with the folded edge. When the inner cover is assembled, the inner cover is directly pressed into the open cavity surrounded by the paper ring and the top cover to engage.

[0035] In the description of the present utility model, it should be noted that when terms such as "upper", "lower", "inner", "outer", "left", "right" and the like indicating orientation or positional relationship appear, it should be understood that the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use, or the orientation or positional relationship commonly understood by those skilled in the art, is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the equipment or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, when terms such as "first" and "second" appear, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and limited, terms such as "installation", "setting", and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
