The specific implementation mode is as follows:

for the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiment examples. The utility model can be implemented by:

referring to fig. 1 to 9, a paper tank for containing engine oil includes a paper tank cylinder 1, and upper and

lower covers

2 and 3 respectively provided at upper and lower openings of the paper tank cylinder 1.

The inner surface of the paper tank cylinder 1 is compounded with an aluminum film 11, and the aluminum film 11 extends to the interface of the paper tank cylinder 1 and the upper cover 2 and the lower cover 3. The inner layer 12 of the paper can barrel 1 is made of kraft paper, and the outer layer 13 is made of bobbin paper. The paper can is used for packaging liquid, is heavy in weight and can be strongly collided in the transportation process, and the craft paper is tough in texture, high in bursting strength, ring crush strength and tearing strength and capable of meeting the strength requirement of the paper can for packaging the liquid; in addition, the craft paper also has higher water resistance, can further prolong the life of paper jar. The bobbin paper is thin vulcanized paper, and the paper is tough and wear-resistant, smooth and even in paper surface and has good water resistance. The aluminum film 11 is compounded on the inner surface of the inner layer 12, and can prevent engine oil from permeating into the paper layer of the paper cylinder 1.

The upper cover 2 and the lower cover 3 are anti-leakage covers, the edge of the cover is provided with a connecting part 230 which is tightly matched with the upper opening and the lower opening of the paper tank, the connecting part 230 comprises a circumferential mounting groove 231 which is tightly connected with the edge of the opening of the paper tank, and the connecting part 230 is provided with an inner groove 232 for injecting glue on one side facing the center of a circle. The opening direction of the inner groove 232 is opposite to the direction of the center of the circle, and one end of the inner groove 232 is connected with one end of the circumferential installation groove 231. Before the installation, pour sealed glue into in inner groove 232 inside earlier, then utilize the rotatory riveting of the last edge joint of circumference mounting groove 231 and paper tank to can. Because the internal surface complex of a paper tank section of thick bamboo 1 has aluminium membrane 11, and aluminium membrane 11 extends to a paper tank section of thick bamboo 1 and the kneck of upper cover 2 and lower cover 3, consequently, after the inside injecting glue of inner groovy 232, glue and aluminium membrane 11 contact back, form and prevent round waterproof sealing circle, can effectively prevent that machine oil from paper cylinder and upper and lower cover 3 joint gap department seepage.

The horizontal plane of the end of the inner groove 232 connected with the circumferential mounting groove 231 is higher than the horizontal plane of the top of the circumferential mounting groove 231. The outer groove surface 2321 of the inner groove 232 is obliquely arranged, and the inner groove surface 2322 is horizontally arranged. The connection surface of the inner groove 232 and the circumferential installation groove 231 is an arc surface. This design can make the lid after the injecting glue in with the riveting in-process of 1 edge of fiber container section of thick bamboo, sealed glue spread on being connected face 2323 with inner grove 232 and circumference mounting groove 231 a small amount, increase the sealed area of contact of gluing and the surface at 1 top edge of fiber container section of thick bamboo, the sealed effect of reinforcing.

The inner volume of the paper tank in the embodiment is slightly larger than 1 liter and is 1.05-1.2 liters, so that 1L of engine oil can be packaged to meet the requirement of engine oil replacement of a motorcycle each time. If the height of the inner groove 232 is 1-2 mm. The inner concave depth of the inner groove 232 is 1.5-2.5 mm.

The upper cover 2 is one of an easy-to-open cover, an easy-to-tear cover, an iron cover or an aluminum cover. The easy-open cover and the easy-tear cover can facilitate the customer to open the upper cover 2 quickly. The lower cover 3 is one of an iron cover or an aluminum cover.

The using method comprises the following steps: the lower cover 3 and the lower edge of the paper can 1 are rotationally riveted after glue injection, then the engine oil is filled in the paper can, and finally the upper cover 2 and the upper edge of the paper can 1 are rotationally riveted after glue injection.

Finally, it should be noted that: the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
