In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a prevent bottom seepage paper cup, includes cup and bottom of cup, the cup is formed by the crooked bonding in square paper container substrate both ends, cup bottom edge downwardly extending forms the turn-ups, the inside and outside surface of cup, bottom of cup is equipped with the coating respectively, folding groove has been seted up to paper container substrate bottom, the folding groove will the bottom portion of cup is cup outer wall, cup inner wall, the cup inner wall is along axial center to folding groove bending type formation hem, the top of bottom of cup with the department of buckling of hem bonds mutually, the turn-ups with the cup outer wall bonds mutually.
Through above-mentioned technical scheme, hide the junction of turn-ups and bottom of a cup in the corner of turn-ups and cup outer wall for the plane at bottom of a cup top is as the loading surface of solution in the paper cup, because the hot melt bonding that drenches the membrane of bottom of a cup surface and edge surface drenches the membrane has sealed the gap between bottom of a cup and the hem, so the solution in the paper cup can't leak to the junction of turn-ups and bottom of a cup, thereby overcome the water in the paper cup and got into the inside not enough of paper container substrate from the junction seepage of turn-ups and bottom of a cup, guaranteed the normal life of paper cup.
Preferably, the bottom of the outer wall of the cup is turned inwards to form a supporting convex edge, and the bottom of the turned edge is adhered and fixed with the top of the supporting convex edge.
Through the technical scheme, as the outer surface of the outer wall of the cup is provided with the coating, the lower surface of the supporting flange is correspondingly coated, so that the end part of the protection flanging can not be directly contacted with the outside, the water in the external environment is prevented from directly contacting with the flanging paper base layer, and the vertical supporting strength of the flanging is ensured.
Preferably, the inner wall of the flanging is in the same plane with the inner wall of the cup body.
Through above-mentioned technical scheme, guaranteed the structural strength of cup body bottom, avoid the too thin unable holistic stiffness of paper cup of guaranteeing of cup body bottom.
Preferably, the end part of the supporting convex edge is bent towards the cup bottom to form a limiting boss.
Through above-mentioned technical scheme, the terminal surface that has guaranteed to support protruding edge that the terminal surface can not be because of not having drenching the membrane protection and cause the paper container substrate to be soaked because of external environment's water, still further guaranteed the intensity and the stiffness of bottom of cup.
Preferably, the outer wall of the limit boss is adhered to the inner wall of the flanging.
Through above-mentioned technical scheme, spacing boss has restricted the radial position of turn-ups, avoids appearing unstable after the bonding of bottom of cup.
Preferably, the top of the cup body is outwards turned to form a cup rim curled edge, and the section of the cup rim curled edge is spiral.
Through the technical scheme, the lip is prevented from directly contacting the top of the paper container base material when drinking water, and the sanitation and safety are ensured.
Preferably, the coating is a PE film.
Through the technical scheme, the PE material has stronger adhesiveness, and the occurrence of unstable adhesion can be avoided during adhesion.
Preferably, the end part of the limit boss is tightly attached to the bottom wall of the cup bottom.
Through the technical scheme, when the paper cup is filled with water, the cup bottom bears larger pressure, so that the limit boss is tightly attached to the bottom wall of the cup bottom, the edge of the cup bottom can bear larger pressure, and gaps between the cup bottom and the folded edges are avoided from being formed due to the fact that the cup bottom is bent.

Detailed Description
The following detailed description of the utility model is provided in connection with the accompanying drawings to facilitate understanding and grasping of the technical scheme of the utility model.
The utility model provides a prevent bottom seepage paper cup, shown in fig. 1, fig. 3, includes cup body 1 and bottom of cup 2, and cup body 1 is formed by the crooked bonding in square paper container substrate 3 both ends, and bottom of cup 2 edge downwardly extending forms turn-ups 4, and cup body 1, bottom of cup 2's inside and outside surface are equipped with respectively and drenches membrane 5, drenches membrane 5 and is PE material drying film technology formed film. The PE material has stronger adhesiveness, and can ensure that unstable adhesion can not occur during adhesion.
As shown in fig. 2 and 4, a folding groove 6 is formed in the bottom of the paper container base material 3, and the folding groove 6 divides the bottom of the cup body 1 into a cup outer wall 7 and a cup inner wall 8. The inner wall 8 of the cup is bent towards the folding groove 6 along the axial center to form a folded edge 9, the top of the cup bottom 2 is adhered to the folded edge 9, the folded edge 4 is adhered to the inner surface of the outer wall 7 of the cup, and the inner wall of the folded edge 4 and the inner wall of the cup body 1 are positioned on the same plane. The bonding connection ensures the structural strength of the bottom of the cup body 1, and avoids the problem that the whole stiffness of the paper cup cannot be ensured due to the fact that the bottom of the cup body 1 is too thin.
As shown in fig. 2, the bottom of the cup bottom 2 of the paper cup is more stressed, so that the bottom of the outer wall 7 of the cup is turned inwards to form a supporting flange 10, and the bottom of the flanging 4 is adhered and fixed with the top of the supporting flange 10. The flange 4 is supported by the supporting convex edge 10, so that the pressure of the cup bottom 2 can be ensured to be larger.
As shown in fig. 2, the end of the supporting flange 10 is bent towards the cup bottom 2 to form a limiting boss 11, the outer wall of the limiting boss 11 is adhered to the inner wall of the flanging 4, and the end of the limiting boss 11 is tightly attached to the bottom wall of the cup bottom 2. The radial position of turn-ups 4 has been restricted to spacing boss 11, avoids the adhesion of bottom of cup 2 to appear unstable, and spacing boss 11 has still guaranteed that the terminal surface that supports protruding edge 10 can not lead to the fact paper container substrate 3 to be soaked because of external environment's water, has further guaranteed the intensity and the stiffness of bottom of cup 2, and the while spacing boss 11 further makes bottom of cup 2 edge can bear bigger pressure, has avoided the gap between bottom of cup 2 and the hem 9 can not appear because of bottom of cup 2 crooked.
As shown in fig. 1, in order to ensure sanitation and safety, the top of the cup body 1 is turned outwards to form a cup rim curl 12, and the cut surface of the cup rim curl 12 is spiral. The helical arrangement is such that the lips do not directly contact the top of the paper container base 3 when drinking water.
Of course, the above is only a typical example of the utility model, and other embodiments of the utility model are also possible, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the utility model claimed.
