Paper bag

Abstract

A paper tote bag includes a front panel, a back panel, a left panel, a right panel, a bottom panel, and two carrying straps. The front and back panels are connected to the bottom panel, and the left and right panels are connected to the back panel. The front panel has two adhesive plates corresponding to the left and right panels, allowing the front panel to be bonded to the left and right panels as one unit. The bottom panel has two adhesive plates on the outer side corresponding to the left and right panels, allowing the two adhesive plates to be bonded to the left and right panels as one unit. The bottom panel has two triangular fold lines on the inner side corresponding to the two adhesive plates. The left and right panels, the bottom panel, and the adhesive plates have a first fold line and a second fold line in the middle, for folding the paper tote bag when it is folded. The flat design of the bottom panel and the upward lifting effect of the adhesive plates prevent the bag from breaking due to weight at the seams. At the same time, the crease-free design of the front and back panels ensures that the advertising logo is intact and unobstructed.

Description

Technical Field

[0001] This utility model of paper tote bag is mainly applied to the folding technology of paper tote bags. In addition to adopting a flat and seamless bottom panel design to make the paper tote bag more sturdy and durable, it also adopts a crease-free design for the front and back panels to ensure that the advertising trademarks are not obscured and to ensure their integrity. Background Technology

[0002] Please see Figure 8 The diagram shown is a three-dimensional representation of a known usage configuration. A typical conventional paper bag 70 is usually made of paper or plastic. This paper bag 70 is composed of a front panel 71, a back panel 72, a left panel 73, a right panel 74, and a bottom panel 75. Two carrying straps 80 are located above the front panel 71 and the back panel 72 for easy carrying. A crease 711 is located on the front panel 71 at approximately half the width of the bottom panel 75. The left panel 74... A pair of fold lines 731 and 741 are respectively provided in the middle of the right panel 74 and the left panel 73. A V-shaped fold line 732 is provided below the fold lines 731 and 741 for folding when the paper bag 70 is folded. The bottom panel 75 is formed by gluing two joint plates 751 together. The left panel 73 and the right panel 74 are provided with two adhesive plates 752 on the left and right sides of the bottom panel 75 for gluing together with the bottom panel 75.

[0003] However, the paper bag 70 has a seam at the junction of the two connecting plates 751 of the bottom panel 75. This seam often results in poor load-bearing capacity at the bottom of the paper bag 70. At the same time, because the bottom panel 75 is only a single-layer structure with the left panel 73 and the right panel 74, the seam is prone to disassembly and damage due to the excessive weight of the contents. This is one of the existing problems and defects that still need to be overcome and resolved.

[0004] In addition, the paper bag 70 has an asymmetrical design with the fold line 711 only on the front panel 71. This makes it more troublesome and inconvenient to assemble when the paper bag 70 is unfolded. At the same time, the contents are prone to tilting due to uneven force. This is the second existing problem and defect that needs to be overcome and resolved.

[0005] Please see Figure 9 The diagram shown is a known three-dimensional representation of the folded state. Furthermore, when the aforementioned conventional paper bag 70 is folded, the bottom panel 75 obscures the advertisements and trademarks on the front panel 71, representing the third existing problem and defect that remains to be overcome. Utility Model Content

[0006] The inventor of this utility model is currently engaged in the manufacturing and design of related products. With many years of practical experience and insights, and in response to the existing problems and defects of traditional paper bags, the inventor has actively devoted himself to innovation and improvement, resulting in the paper bag.

[0007] The technical means applied by this utility model to solve the problem and the advantages compared with the prior art are as follows: the front and rear panels are connected to the bottom panel, and the left and right panels are connected to the rear panel.

The bottom panel has two adhesive plates corresponding to the outer side of the left and right panels, so that the two adhesive plates are bonded to the left and right panels as a whole. The bottom panel has two triangular fold lines corresponding to the inner side of the two adhesive plates. The left and right panels, the bottom panel, and the adhesive plates have a pair of fold lines in the middle, which are used for folding the paper bag when it is folded. In addition to utilizing the flat design of the bottom panel and the upward lifting effect of the adhesive plates to avoid disassembly and damage at the seams due to weight; at the same time, the crease-free design of the front and rear panels ensures that the advertising trademark is intact and unobstructed. Moreover, the completely symmetrical design makes it easy to fold and unfold, saving time and labor during assembly. It has improved efficiency and achieves its main purpose.
