Description

Technical Field

[0001] The utility model relates to a paper cup, and particularly to a paper cup with an anti-seepage bending structure. Background Art

[0002] At present, a Chinese patent with the authorization announcement number CN205125817U discloses a paper cup, which includes a paper layer. The paper cup further includes a barrier layer, and the barrier layer is an aluminized layer or a high-barrier layer. Both the high-barrier layer and the aluminized layer have excellent barrier effects on liquids, and can very effectively prevent the liquid inside the paper cup from penetrating to the outside of the paper cup.

[0003] However, in the production of such a paper cup, usually a large piece of paper is cut into small pieces by a cutting machine, and then the side walls at both ends of the small pieces of paper are fixed to obtain the cup wall of the paper cup. Since the end face of the small piece of paper does not have the ability to block water after cutting, after bending to obtain the cup wall, the water in the cup will penetrate into the inside of the paper from the end face of the paper, so that the paper layer will be soaked, softened and separated from other layers, that is, the paper is prone to delamination and damage. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a paper cup with an anti-seepage bending structure to achieve the purpose of making the paper not easily damaged.

[0005] To solve the above technical problems, the technical solution of the utility model is: a paper cup with an anti-seepage bending structure, including a cup bottom and a cup wall. The cup bottom is connected to the bottom of the cup wall. The cup wall is formed by bending both ends of a piece of paper. A protective layer is coated on the piece of paper and the cup bottom. One end of the piece of paper is a bending part, and the other end is a fixing part. The bending part is bent outward of the cup wall, and the fixing part is fixedly connected to the bending part.

[0006] To implement the above technical solution, after folding the bending part in half, then fix the fixing part to the bending part. Pour water into the cavity formed by the cup wall and the cup bottom. Since the bending part bends the end of the piece of paper outward, so that the protective layer contacts with the water, thus playing a water-blocking effect to prevent water from penetrating into the paper from the end of the piece of paper, so that the paper cup can be used for a long time and is not easily damaged.

[0007] As a preferred solution of the utility model, the thickness of the bending part is less than the thickness of the fixing part.

[0008] To implement the above technical solution, after folding the bending part in half, the thickness of the bending part can be reduced, so that when the fixing part is fixedly connected to the bending part, the occupied space volume can be smaller and it is more comfortable to hold the cup wall.

[0009] As a preferred embodiment of the present utility model, the bent portion includes an integrally provided connecting portion and a folding portion. The connecting portion is connected to the fixing portion, the folding portion corresponds to the connecting portion, a plurality of first protrusions are connected to the connecting portion, a plurality of second protrusions are connected to the folding portion, the first protrusions are embedded between two second protrusions, and the second protrusions are embedded between two first protrusions.

[0010] To implement the above technical solution, move the folding portion towards the connecting portion, so that the first protrusions are embedded between two second protrusions. At the same time, the second protrusions are embedded between two first protrusions. There is a large frictional force between the folding portion and the connecting portion, so that the folding portion and the connecting portion are more stable, in order to avoid the folding portion and the connecting portion from being easily loosened when holding more water.

[0011] As a preferred embodiment of the present utility model, a first card slot is provided on one side of the first protrusion, a first convex portion is connected to the other side of the first protrusion, a second card slot is provided on one side of the second protrusion, and a second convex portion is connected to the other side of the second protrusion. The first convex portion is embedded in the second card slot, and the second convex portion is embedded in the first card slot.

[0012] To implement the above technical solution, make the first protrusions embedded between two second protrusions. At the same time, the second protrusions are embedded between two first protrusions. There is a large frictional force between the folding portion and the connecting portion, so that the folding portion and the connecting portion are more stable, in order to avoid the folding portion and the connecting portion from being easily loosened when holding more water.

[0013] As a preferred embodiment of the present utility model, a folding groove is provided at the connection between the connecting portion and the folding portion.

[0014] To implement the above technical solution, it is easier for the folding portion to be connected to the connecting portion along the folding groove.

[0015] As a preferred embodiment of the present utility model, the cup bottom includes a supporting portion and an annular portion. The annular portion is fixed to the edge of the supporting portion. The annular portion is fixedly connected to the inner wall of the cup wall. A heat insulation board is connected to the inner wall of the annular portion. A heat insulation layer is formed between the heat insulation board and the supporting portion.

[0016] To implement the above technical solution, fix the annular portion to the inner wall of the cup wall, and then fix the heat insulation board to the annular portion. There is air between the heat insulation board and the supporting portion to form a heat insulation layer.

[0017] As a preferred embodiment of the present utility model, a reinforcing rod is provided in the heat insulation layer. The reinforcing rod is inclined and one end is connected to the supporting portion, and the other end is connected to the heat insulation board.

[0018] Implementing the above technical solution, the setting of the reinforcing rod enhances the structural strength of the supporting part, thereby enabling it to bear more water.

[0019] As a preferred solution of the present utility model, a heat preservation hole is provided along the axis of the reinforcing rod.

[0020] Implementing the above technical solution further improves the heat preservation performance.

[0021] As a preferred solution of the present utility model, one end of the cup wall facing away from the cup bottom is bent outward to form a curling part.

[0022] Implementing the above technical solution, the mouth contacts the curling part so that water is not easily immersed into the paper from the upper end of the cup wall.

[0023] As a preferred solution of the present utility model, the protective layer includes a water-based acrylic coating.

[0024] Implementing the above technical solution, the water-based acrylic coating has the advantages of being environmentally friendly, non-toxic, re-pulpable, recyclable, and insoluble in water and alcohol, and can be used for drinking water and alcohol. BRIEF DESCRIPTION OF THE DRAWINGS
