Drawings
FIG. 1 is a schematic view of the overall structure of a leakproof paper cover of the present invention;
reference numerals: 1. an upper cover portion; 2. a lower cover portion; 3. a curled portion.
Detailed Description
The following describes a specific embodiment of the leakproof paper cover of the present invention with reference to fig. 1. The utility model relates to a leak protection paper lid is not limited to the description of following embodiment.
Example 1:
the embodiment provides a specific structure of a leakproof paper cover, as shown in fig. 1, the paper cover comprises an upper cover part 1 made of paper and a lower cover part 2 made of paper, wherein the edge of the upper cover part 1 is folded downwards, the edge of the lower cover part 2 is folded upwards, the downward folded part of the upper cover part 1 is inserted into the upward folded lap seam of the lower cover part 2 and is connected by adhesion, the edge of the upward folded part of the lower cover part 2 is provided with a curled part 3 which is curled outwards, and the lower cover part 2 and the curled part 3 are integrally formed.
The upper cover part 1 adopts a circular structure, and the lower cover part 2 adopts a cylindrical structure.
By adopting the technical scheme:
because the rim of a cup of current paper cup or the bowl mouth of paper bowl are big many and take certain angle, consequently adopt the utility model discloses in the time of well paper lid from inside lid income, the paper lid can be because the atress warp and form sealed face, has promoted the sealed effect of paper lid and paper cup or paper bowl.
The edge of the lower cover part is provided with the curled part 3 which is curled outwards, the curled part 3 can increase the stiffness of the paper cover, prevent the paper cover from being covered too deeply, and can form secondary sealing with the cup mouth of the paper cup or the bowl mouth of the paper bowl, so that the leakage-proof effect is further improved, the cover can be conveniently taken out, and the effect of repeated use is achieved;
because the lower cover part 2 of the paper cover can be clamped into the paper cup or the paper bowl when the paper cover is closed, the paper cover occupies less external space when in use and is easier to pack.
Example 2:
the embodiment provides a specific structure of a leakproof paper cover, as shown in fig. 1, the paper cover comprises an upper cover part 1 made of paper and a lower cover part 2 made of paper, wherein the edge of the upper cover part 1 is folded downwards, the edge of the lower cover part 2 is folded upwards, the downward folded part of the upper cover part 1 is inserted into the upward folded lap seam of the lower cover part 2 and is connected by adhesion, the edge of the upward folded part of the lower cover part 2 is provided with a curled part 3 which is curled outwards, and the lower cover part 2 and the curled part 3 are integrally formed.
The upper cover part 1 adopts a circular structure, and the lower cover part 2 adopts a cylindrical structure.
The edge of the upper cover part 1 adopts a sawtooth structure.
Example 3:
the embodiment provides a specific structure of a leakproof paper cover, as shown in fig. 1, comprising an upper cover part 1 made of paper and a lower cover part 2 made of paper, wherein the edge of the upper cover part 1 is folded downwards, the edge of the lower cover part 2 is folded upwards, the downward folded part of the upper cover part 1 is inserted into the upward folded lap seam of the lower cover part 2 and is connected by adhesion, the edge of the upward folded part of the lower cover part 2 is provided with a curled part 3 which is curled outwards, and the lower cover part 2 and the curled part 3 are integrally formed.
