Description

Technical Field

[0001] The utility model relates to the technical field of paper bag packaging, and more particularly to a laminated paper bag that is not easily deformed. Background Art

[0002] Laminated paper bags are paper bags coated with a layer of plastic film (usually polyethylene) on the surface of paper. This type of paper bag has certain waterproof, oil-proof and moisture-proof properties, so that the items in the paper bag can be better protected. Laminated paper bags are widely used in food packaging (such as bread bags, cake bags), clothing packaging, gift packaging and other fields. The lamination process can enhance the strength and durability of the paper bag, and also make the surface of the paper bag smoother and the printing effect better. In addition, laminated paper bags are relatively environmentally friendly and can replace some plastic products to a certain extent, reducing pollution to the environment.

In addition, laminated paper bags are relatively environmentally friendly and can replace some plastic products to a certain extent, reducing pollution to the environment.

[0025] The Chinese patent publication number CN220640905U discloses a sealed paper bag, comprising: a bag body, the bag body comprising an open end, a first wrapping portion and a second wrapping portion, the first wrapping portion and the second wrapping portion both being provided with a carrying hole; a sealing sheet, the sealing sheet being provided at the upper end of the first wrapping portion for closing the open end, the sealing sheet being provided with a first through hole, an adhesive portion and an adhesive sheet, the adhesive sheet being located at the opening of the first through hole and one end of the adhesive sheet being connected to the sealing sheet; wherein, when the sealing sheet closes the open end, the adhesive portion is adhesively fixed to the outer side of the second wrapping portion, the first through hole is communicated with the carrying hole, the other end of the adhesive sheet passes through the carrying hole and is adhesively fixed to the outer side of the first wrapping portion; the beneficial effect of the utility model is that the sealing sheet is adhesively fixed to the outer side of the second wrapping portion by the adhesive portion, thereby playing a sealing role; then, the adhesive sheet is used to make the first wrapping portion and the second wrapping portion fit together, thereby preventing dust or small debris from entering the paper bag and improving privacy during delivery.

[0026] However, the above-mentioned prior art solutions have the following defects: when the laminated paper bag is shaken while containing articles, the articles in the bag shake back and forth, exerting a force on the bag body, which may cause the bag body to deform or break.

[0027] Therefore, it is necessary to provide a laminated paper bag that is not easily deformed to solve the above problems.

[0028] Based on this, the problem of easy deformation of laminated paper bags existing in the related art can be improved.

[0029] See also Figure 1 and Figure 3 A laminated paper bag that is not easily deformed comprises a bag body 1 and an anti-deformation component 2.

[0030] With such arrangement, the anti-deformation component 2 prevents items in the bag body 1 from deforming the laminated paper bag.

[0031] Optionally, in some embodiments, see Figure 2 and Figure 3The anti-deformation component 2 includes a first reinforcement strip 21, a second reinforcement strip 22 and a support strip 23. The first reinforcement strip 21 and the second reinforcement strip 22 are arranged on the inner wall of the side of the bag body 1. One end of the support strip 23 is connected to the first reinforcement strip 21, and the other end of the support strip 23 is connected to the second reinforcement strip 22. The first reinforcement strip 21 and the second reinforcement strip 22 are provided in two groups, and the support strip 23 is provided in four groups. The anti-deformation component 2 also includes a reinforcement ridge 24, which is provided on the bottom end of the bag body 1. The bag body 1 is also provided with a side piece 3 and a bottom piece 4. One side of the side piece 3 It abuts against the side of the first reinforcement strip 21 away from the bag body 1, and one side of the bottom film 4 abuts against the side of the reinforcement edge 24 away from the bag body 1. The bag body 1 is also provided with a paper cover 5, and the paper cover 5 is connected to the end of the bag body 1 away from the bottom film 4. A Velcro sub-surface 6 is provided on the outer peripheral surface of the bag body 1, and a Velcro mother surface 7 is provided on the side of the paper cover 5 close to the bag body 1. Fixed rings 9 are fixed on both sides of the outer wall of the bag body 1, and a lifting strap 8 is passed through the fixing ring. The lower end of the lifting strap 8 abuts against the bottom end of the bag body 1, and a protective pad 10 is provided at the top of the lifting strap 8, and there are multiple protective pads 10.

[0032] With such a configuration, when the laminated paper bag is needed, the articles are placed in the bag body 1. When the laminated paper bag shakes, the articles in the bag exert a force on the paper bag. The anti-deformation component 2 adds a first reinforcement strip 21 and a second reinforcement strip 22 to the side of the laminated paper bag, which reduces the degree of deformation of the laminated paper bag caused by the force generated by the movement of the articles in the bag body 1, improves the deformation ability of the side of the laminated paper bag, improves the stability of the laminated paper bag, and then improves the load-bearing capacity of the laminated paper bag, avoids the deformation of the laminated paper bag, and ensures the safety of the articles in the packaging box. The reinforcement ridge 24 at the bottom of the laminated paper bag has a supporting effect on the bottom of the laminated paper bag, preventing the articles in the bag body 1 from being too heavy and causing damage to the bottom of the laminated paper bag. The phenomenon of deformation or damage is prevented, thereby improving the load-bearing capacity of the laminated paper bag and avoiding deformation of the laminated paper bag. After the items are put into the laminated paper bag, the Velcro surface on the paper cover 5 is glued to the Velcro mother surface 7 on the laminated paper bag to seal the top of the laminated paper bag to prevent the items in the bag from being contaminated or falling out. The hand rope is convenient for users to extract the laminated paper bag, which improves the portability. Because the pulling belt 8 passes through the bottom of the paper bag and is fixed by the fixing ring 9, the bearing capacity of the bottom of the paper bag is strengthened to avoid deformation of the paper bag. Because of the setting of the pad 10, when the user extracts the paper bag, if the weight is heavy, it can effectively protect the fingers, increase the contact area between the fingers and the pulling belt 8, and extract the paper bag more easily.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
