Preferably, the height of the circumferential necking is 20% -30% of the height of the covering part.
Preferably, the bottom edge of the outer can is provided with an inner curled edge, and the bottom of the inner can is abutted to the top of the inner curled edge of the outer can.
Preferably, the top edge of the can lid is provided with an internal bead.
Preferably, the inner layer of the outer tank is made of kraft paper, and the outer layer is made of trademark paper.
Preferably, the inner layer of the tank cover is made of kraft liner paper, and the outer layer of the tank cover is made of trademark paper.
Preferably, the inner layer of the inner tank is made of kraft paper.
Preferably, paper pads are arranged at the top of the tank cover and the bottom of the inner tank, the paper pads are white paper boards, and trademark paper is arranged on the outer surfaces of the white paper boards.
Preferably, the circumferential surface of the paper tank body is provided with a through hole for the wrist rope to pass through.
Compared with the prior art, the utility model has the following advantage:
1. the utility model discloses a paper tank, the lateral surface through the portion top that closes at the lid of the paper tank body is provided with the circumference throat that conveniently closes the lid, and the circumference throat is to centre of a circle direction indent for the external diameter at the top that the lid closed the portion is less than the internal diameter of cover, thereby makes the cover close with paper tank body lid easily. In addition, the height of the circumferential necking is 20% -30% of that of the covering part, so that the enough contact surface between the cover and the covering part is ensured to provide enough friction force for tightly covering the paper can body and the cover, and the cover is not easy to fall off from the paper can body.
2. The utility model discloses a paper can, the edge at the bottom edge of its lid portion top edge, outer jar and the top of cover all is provided with interior turn-up, in pleasing to the eye, can also strengthen the crushing resistance of paper can, prolongs the life of paper can.
3. The utility model discloses a paper tank adopts craft paper and white board to make, has strengthened the compressive capacity of paper tank.

The specific implementation mode is as follows:
in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:
referring to fig. 1-4, a paper can convenient for capping comprises a cylindrical paper can body 1 and a can cover 2 covering the paper can body 1, wherein the paper can body 1 comprises an outer can 11 and an inner can 12, and the top of the inner can 12 protrudes from the outer can 11 to form a covering part 13 covering the can cover 2.
The outer side surface of the top of the covering part 13 is provided with a circumferential necking 14 which is convenient for covering, the circumferential necking 14 is concave towards the direction of the circle center, and the contact position of the covering part 13 and the tank cover 2 is in sliding fit. The circumferential necking 14 is concave towards the direction of the circle center, so that the outer diameter of the top of the covering part 13 is smaller than the inner diameter of the can cover 2, and the can cover 2 is easily covered with the paper can body 1. The height of the circumferential necking 14 is 20-30% of the height of the covering part 13, so that the enough contact surface between the cover 2 and the covering part 13 is ensured to provide enough friction force for tightly covering the paper can body 1 and the cover 2, and the cover 2 is ensured not to easily fall off from the paper can body 1.
