Fig. 1-3 show a waterproof and heat-insulating paper-plastic barrel provided by the utility model, which comprises a barrel body 1 which has waterproof and heat-insulating functions and is used for containing solid and liquid by adding a waterproof agent into slurry, performing wet blank forming and then dry-pressing the paper-plastic, and a barrel cover 2 which is arranged on the barrel body 1 for performing sealing and heat-insulating functions and is used for covering the barrel body 1 by wet-pressing forming; the barrel cover 2 is provided with raised steps 3 for supporting the barrel cover 2 on the barrel body 1, and the top of the barrel body 1 is provided with inner steps 4 for supporting the barrel cover 2 in cooperation with the raised steps 3. The side surface and the bottom surface of the barrel body 1 are provided with concave steps 5 for increasing the structural strength of the barrel body 1 in the vertical direction. The top of the barrel body 1 is also provided with an outer step 6 which is used for increasing the structural strength of the barrel body 1 in the horizontal direction and providing a supporting point for the barrel cover 2. The paper-plastic barrel is a square paper-plastic barrel. The barrel cover 2 is produced by adopting a white composite wet paper pressing support process, in order to keep the neatness of the appearance to the maximum extent, the raised steps 3 on the periphery of the barrel cover 2 play a role in supporting the barrel cover 2 and enhancing the strength of the barrel cover 2, after the barrel cover 2 is covered, the raised steps 3 of the barrel cover 2 just step on the inner steps 4 of the barrel body 1 to ensure that the barrel cover 2 does not collapse, when the barrel body 1 is manufactured, a waterproof agent is added into formed slurry, so that the whole barrel body 1 has a waterproof function and has more uniform effect, the barrel body 1 has higher waterproof grade, and the effects of containing water, serving as an ice barrel, planting flowers and plants and the like outside the derivative package and the storage of the paper-plastic barrel can be promoted, so as to promote the environmental protection, and in order to ensure that the waterproof performance of the barrel body 1 is not damaged, the barrel body 1 controls the shaping time and pressure to just slightly level each plane of the shape hot-pressing rule of the barrel body 1 during shaping, adopt dry paper pressing and moulding technology, start from the thickness and the structure of staving 1, strengthen the intensity of staving 1, in order to ensure that it accomodates and the bearing, staving 1 is when wet embryo shaping, inhale thick liquid one minute, inhale the thick liquids that will be thicker than traditional dry paper pressing and moulding, guarantee to have 5 mm's thickness after drying in line with, inwards concave step 5 of indent is all done to the side of staving 1 and bottom surface, can play the effect of muscle position when increasing staving 1 at vertical direction structural strength, reduce the shaping and dry the deformation of in-process staving 1, round outer step 6 is also done to the vertical direction of staving 1, can effectual increase staving 1 at horizontal direction structural strength, give 2 strong points of bung when effectively resisting horizontal effort.

The paper plastic barrel further comprises an outer barrel body 6 and an outer barrel cover 7, wherein the bottom and the top of the outer barrel body are bonded with the barrel body 1, a cavity structure is formed around the outer barrel body, and the periphery of the outer barrel cover is bonded with the barrel cover 2. Wrist holes 9 for conveniently lifting the paper plastic barrel are arranged on two opposite sides of the outer barrel body 6. The outer barrel body 6 is made of corrugated paper boards. The outer barrel cover 7 is a whole plane except a packaging position, and the mesh surface is in the inner side when the barrel body 2 is molded by absorbing slurry, so the outer surface is rough, the problem that the rough surface is not attractive and the printing effect is not good is solved, so the corrugated board is manufactured into the outer barrel body 6 which is pasted and fixed on the outer side of the barrel body 1, and the surface of the outer barrel body 6 can be printed, the bottom and the top of the outer barrel body 6 are bonded with the barrel body 1, a certain cavity is reserved around the outer barrel body, a certain heat preservation effect can be achieved, wrist holes 9 are reserved on the short side surface of the outer barrel body 6, and a user can conveniently lift the paper plastic barrel.

The paper-plastic barrel realizes a waterproof function, has a certain heat preservation function, has the same strength and bearing capacity with the traditional plastic barrel, is basically not problematic when used as a common storage barrel, a fresh-keeping barrel, an ice barrel and a water barrel, can be adaptively adjusted according to the barrels with different purposes when manufactured, namely the manufactured ice barrel as shown in figure 3, the ice barrel is the ice barrel which is manufactured by arranging a recess and an opening on the barrel cover 2, arranging a cup on the outer barrel cover 7 and arranging an opening which is matched with the opening of the barrel cover 2 and used for placing a bottle mouth outside, and adopts recycled paper as a raw material, so that the environmental pressure can be effectively reduced, the overall shape of the paper-plastic barrel is rectangular, the space can be more effectively utilized compared with a circular paper-plastic barrel, the volume under the same size is larger, the space utilization rate is higher when stacking is carried out, and the upper surface of the paper-plastic barrel cover 2 can be a flat surface (depending on the use of the barrel, if the bucket is a flat surface, the other surfaces can be changed according to requirements), the lower surface is provided with the protruding steps 3 which step on the inner steps 4 of the bucket body 1 so as to achieve the purpose that articles are placed on the surface of the bucket cover 2 and do not collapse, the outer bucket body 6 is bonded with the bucket body 1 to be matched for use, and the appearance, the strength and the heat insulation performance of the whole paper-plastic bucket are all helped.

This kind of paper plastic barrel adopts 100% recovery paper as raw and other materials, realize that waste product recycle reduces the environmental pressure, and the recovery paper is degradable, can not cause environmental pollution after scrapping yet, the water repellent has been done to the staving, can reach waterproof 48 hours performance and do not descend, paper plastic barrel outward appearance is square, have great internal volume and increased the space utilization when piling up, paper plastic barrel is the dry pressing paper product of moulding, the thickness of doing 5mm is 2 times or even more than 2 times of traditional dry pressing paper thickness of moulding, in order to increase its intensity, the bung adopts wet pressing technology production, it is pleasing to the eye to strengthen it, and outer barrel lid is packing position, can carry more article when making things convenient for the user to use, the staving uses with outer staving jointly, not only strengthened the intensity of paper plastic barrel, and solved the problem that the coarse printing effect in dry pressing paper plastic product surface.

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 and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
