Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly packaging technology, and more specifically, it relates to an environmentally friendly paper bag. Background Technology

[0002] Most eco-friendly paper bag handles are made of rolled paper and are attached to the bag body using only conventional adhesives. This structure has significant drawbacks: the handles themselves have low tensile strength and are prone to breakage and deformation when bearing even slightly heavy items (over 500g); furthermore, the connection relies solely on adhesive without mechanical fixation, making it prone to separation and detachment at the adhesive joint when the load increases or is subjected to sudden tensile force. This limits its application in packaging medium to heavy items, resulting in poor overall performance. Therefore, this utility model proposes an eco-friendly paper bag. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an environmentally friendly paper bag with strong load-bearing capacity and reliable safety.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to an environmentally friendly paper bag, which includes a paper bag body. The paper bag body includes two paper bag sheets arranged symmetrically front to back. Each of the paper bag sheets is provided with a handle made of twisted paper into a rope. The handle includes a gripping part and connecting parts at both ends of the gripping part. Each of the connecting parts is matched with a row of at least three transverse holes arranged vertically at intervals. The transverse holes are opened on the paper bag sheet. Each of the connecting parts passes through all the matching transverse holes from top to bottom.

[0005] The outer end face of the paper bag is covered with outer adhesive tape, which is also attached to the connecting part located on the outside of the paper bag body; the inner end face of the paper bag is covered with inner adhesive tape, which is also attached to the connecting part located on the inside of the paper bag body.

[0006] The present invention is further configured such that: the end of the connecting part not connected to the gripping part has a tail fin part that is twisted into the shape of a fish fin, and the tail fin part is bonded to the paper bag face paper by an adhesive.

[0007] The present invention is further configured such that the tail fin is located on the inner side of the paper bag body.

[0008] The present invention is further configured such that the outer tape and the inner tape are both bonded to the connecting part in a symmetrical manner from left to right.

[0009] The present invention is further configured such that the spacing between adjacent transverse holes in the same column is equal.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. Through the synergistic effect of enhanced adhesion design and special connection structure, the tensile strength at the connection point is increased by 2-3 times compared to the traditional method, which can stably support items weighing 1-2kg, thus expanding the applicable scenarios.

[0012] 2. The combination of mechanical bonding and enhanced adhesion provides dual protection, reducing reliance on a single adhesive, enhancing resistance to environmental interference, and dispersing stress to prevent paper tearing, thus extending the lifespan of the paper bag.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 3 As shown, the environmentally friendly paper bag involved in this embodiment includes a paper bag body 100, which includes two paper bag face sheets 101 arranged symmetrically front to back. Each of the paper bag face sheets 101 is provided with a handle 200 made of paper twisted into a rope. The handle 200 includes a grip portion 201 and connecting portions 202 provided at both ends of the grip portion. Each of the connecting portions 202 is matched with a row of horizontal cut holes 102 arranged vertically at intervals and numbering no less than three. The horizontal cut holes 102 are opened on the paper bag face sheets 101. Each of the connecting portions 202 passes through all the matching horizontal cut holes 102 from top to bottom.

[0020] The outer end face of the paper bag face 101 is covered with an outer adhesive tape 301, and the outer adhesive tape 301 is also attached to the connecting part 202 located on the outside of the paper bag body; the inner end face of the paper bag face 101 is covered with an inner adhesive tape 302, and the inner adhesive tape 302 is also attached to the connecting part 202 located on the inside of the paper bag body.

[0021] Furthermore, the outer tape 301 and the inner tape 302 are both bonded to the connecting part 202 in a symmetrical manner.

[0022] Furthermore, the spacing between adjacent transverse holes 102 in the same column is equal.

[0023] In this embodiment, when each connecting part 202 passes through all the corresponding transverse cut holes 102 from top to bottom, the connecting part 202 will be slightly bent under the lateral force of the intersecting transverse cut holes 102. Combined with inner and outer adhesive tape, this allows for a tight connection with the paper bag face paper 101. Because the extension direction of the connecting part 202 is no longer a straight line, its anti-detachment ability under tension is improved, making the paper bag more load-bearing.

[0024] In this way, by bonding the outer tape 301 and the inner tape 302 to the connecting part 202 in a symmetrical manner, the connecting part 202 is subjected to balanced force on both sides when it is under tension.

[0025] Example 2

[0026] See Figures 1 to 3 As shown, the environmentally friendly paper bag involved in this embodiment is further configured based on embodiment 1, wherein the end of the connecting part 202 that is not connected to the gripping part has a tail fin part 203 that is rolled into a fish fin shape, and the tail fin part 203 is bonded to the paper bag face paper 101 by an adhesive.

[0027] Furthermore, the tail fin portion 203 is located on the inner side of the paper bag body 100.

[0028] In this embodiment, by providing a tail fin portion 203 that is adhered to the paper bag face paper 101, it plays a dual role in enhancing adhesion, reducing the dependence on a single adhesive, and making the connection strength between the connecting portion 202 and the paper bag face paper 101 higher.

[0029] The environmentally friendly paper bag involved in this utility model, through the synergistic effect of enhanced adhesion design and special connection structure, increases the tensile strength at the connection point by 2-3 times compared to the traditional method, and can stably bear 1-2kg of items, expanding the applicable scenarios; and adopts dual protection of mechanical connection and enhanced adhesion, reducing the dependence on a single adhesive, making it more resistant to environmental interference, while dispersing the stress to avoid tearing of the paper material, extending the service life of the paper bag, with complete overall functions and strong practicality.
