Description

Technical Field

[0001] The utility model relates to the field of shopping paper bags, in particular to a rope-free paper bag with a folding roll structure at the top. Background Art

[0002] Hand-held shopping paper bags are a common type of container in major business districts, and are particularly widely used in the clothing consumption industry. Shopping paper bags are generally not products that are used for a long time. Their main function is to wrap products. The most common structure of a shopping paper bag is a bag body with an open top, and two lifting ropes are fixed on the top of the bag body. The lifting ropes are generally braided ropes or spirally twisted paper ropes.

[0003] In addition, there are also shopping paper bags without carrying ropes, which is equivalent to opening a handle hole on the side of the bag body, which can also serve as a grip. However, since the handle hole is generally located in the material of a single-layer paper bag, its tensile strength is obviously not as good as the structural strength of a braided rope or spiral paper rope, so this type of shopping paper bag cannot bear heavier items and its application scenarios are limited. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a paper bag without a handle rope with a folding roll structure on the top, thereby providing a shopping paper bag without a traditional handle rope, and still using a handle hole for gripping, but using the folding roll structure above the handle hole, thereby greatly improving the structural strength above the handle hole, so that the shopping paper bag can carry heavier items.

[0005] In order to solve the above problems, the utility model provides a rope-free paper bag with a folding roll structure at the top. In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0006] The rope-free paper bag with a folding roll structure at the top comprises: a bag body with an upper opening at the top; a handle hole penetrating the side of the bag body; a reinforcing plate attached to the bag body in a horizontal direction and located above the handle hole; a reinforcing wire attached to the bag body in a vertical direction and the top of the reinforcing wire contacts the reinforcing plate; the bag body above the handle hole is rolled to one side to form a folding roll and the reinforcing plate is accommodated therein.

[0007] The beneficial effect of adopting the above technical solution is: this technical solution provides a shopping paper bag that does not require a traditional carrying rope, and still uses the handle hole for gripping, but greatly improves the structural strength above the handle hole, so the bag body can hold heavier items.

[0008] First, the bag body is rolled and folded to increase the number of paper layers above the handle hole and improve structural strength.

[0009] The second is to use reinforcement plates to improve the bending strength of the structure. At the same time, the reinforcement plates are also convenient for guiding the relatively soft bag body to fold and roll, which is convenient for personnel operation.

[0010] Third, the reinforcing wire can also increase the tensile strength of the structure to a certain extent, prevent the bag from tearing, and further facilitate the bag to be rolled and formed into a folded roll.

[0011] The folding roll has excellent bending structural strength and load-bearing performance. Compared with the handle hole of the single-layer paper style, the folding roll also improves the comfort of hand grip.

[0012] As a further improvement of the utility model, the reinforcing wire is plastically deformed as the bag body is wound, and the reinforcing wire is a metal wire.

[0013] The beneficial effect of adopting the above technical solution is that the plastic deformation can prevent the folding roll from falling apart at will, thereby ensuring its stability.

[0014] As a further improvement of the utility model, the reinforcing wire is attached to the bag body through lining paper, and the width of the lining paper is greater than the width of the reinforcing wire.

[0015] The beneficial effect of adopting the above technical solution is that because the reinforcing wire is very thin, the lining paper can assist in fixing the reinforcing wire and prevent the reinforcing wire from bursting the paper bag.

[0016] As a further improvement of the utility model, the length of the lining paper is not less than the length of the reinforcing wire, the bottom of the reinforcing wire is not higher than the bottom edge of the handle hole; the length of the reinforcing plate is greater than the length of the handle hole.

[0017] The beneficial effect of adopting the above technical solution is to ensure that the bag body in the section above the handle hole is specifically strengthened.

[0018] As a further improvement of the utility model, the reinforcing plate, the reinforcing wire, the lining paper and the inner wall of the bag body are glued and fixed, and the reinforcing wire is wrapped by the glue and is located between the lining paper and the bag body.

[0019] The beneficial effect of adopting the above technical solution is that the gluing method does not affect the appearance and is also a very convenient assembly method.

[0020] As a further improvement of the utility model, reinforcing wires and lining paper are adhered to both sides of the handle hole.

[0021] The beneficial effect of adopting the above technical solution is: ensuring a symmetrical shape.

[0022] As a further improvement of the utility model, the bag body is composed of two pieces of rectangular paper, each piece of rectangular paper is provided with a handle hole, and the distance from the handle hole to the top of the bag body is smaller than the distance from the handle hole to the bottom of the bag body.

[0023] The beneficial effect of adopting the above technical solution is that the area below the handle hole is the actual storage area.

[0024] As a further improvement of the utility model, the inner diameter of the flip roll is greater than the width of the reinforcing plate, and the distance from the handle hole to the top of the bag body is at least greater than three times the width of the reinforcing plate itself.

[0025] The beneficial effect of adopting the above technical solution is: ensuring the winding degree of the folded roll. If the winding degree is too light, a tubular structure cannot be formed.

[0026] As a further improvement of the utility model, the bag body and the lining paper are kraft paper, and the reinforcing plate is a corrugated paperboard with a thickness greater than that of the kraft paper.

[0027] The beneficial effect of adopting the above technical solution is that the mechanical properties of kraft paper and corrugated paper just meet the requirements.

[0028] As a further improvement of the present invention, both ends of the handle hole are provided with inner fillets.

[0029] The beneficial effect of adopting the above technical solution is that the fillet can avoid stress concentration. BRIEF DESCRIPTION OF THE DRAWINGS
