[0029] In the following description, the details of the present invention are set forth as preferred embodiments. It will be apparent to those skilled in the art that modifications, including additions and / or substitutions, may be made without departing from the scope and spirit of the present invention. Specific details may be omitted so as not to obscure the present invention; however, this disclosure is written to enable those skilled in the art to practice the teachings herein without undue experimentation.

[0030] Figure 1This is a perspective view of a foldable paper bag according to one embodiment. In this embodiment, the foldable paper bag 1 has two planar panels 10 and 12, two perforated panels 11 and 13, and a bottom panel 14. Perforated panel 11 connects the planar panels 10 and 12 at one edge, and perforated panel 13 connects the planar panels 10 and 12 at another parallel edge. Bottom panel 14 connects perforated panels 11 and 13 and the planar panels 10 and 12. Planar panels 10 and 12 are parallel, and perforated panels 11 and 13 are also parallel. Planar panels 10 and 12, perforated panels 11 and 13, and bottom panel form a tubular cavity.

[0031] The perforated plate 11 has a plurality of perforations 114. Specifically, the perforated plate has a first series of perforations 114A, a second series of perforations 114B, and a third series of perforations 114C. The first series of perforations 114A is arranged along a first straight line, which is parallel to the normal to the surface of the base plate 14 in the carrying mode. In the carrying mode, the foldable paper bag 1 is opened and in an upright position.

[0032] The second series of perforations 114B is arranged along a second straight line, and the third series of perforations 114C is arranged along a third straight line. One end of the first straight line is adjacent to the opening 15 of the foldable paper bag 1, and the other end of the first straight line is adjacent to one end of the second straight line and one end of the third straight line. In other words, the first, second, and third straight lines defined by the positions of the perforations 114 generally meet at the lower portion of the perforated plate 11.

[0033] The other end of the second straight line defined by the second series of perforations 114B is connected to the side or edge connecting the perforated plate 11 and the flat panel 10. The other end of the third straight line defined by the third series of perforations 114C is connected to the other side or edge connecting the perforated plate 11 and the flat panel 12.

[0034] In this embodiment, the perforated plate 11 has perforations 114 arranged in an inverted "Y" shape. When the foldable paper bag 1 is in an upright position, each arm of the inverted "Y" shape is connected to one of the vertical edges of the perforated plate 11, and the legs of the inverted "Y" shape extend vertically toward the opening 15 of the foldable paper bag.

[0035] In this embodiment, perforations 114 on the perforated plate 11 divide the plate 11 into a front section 110, a rear section 111, and a lower section 112. When the foldable paper bag 1 is in an upright position, the front section 110 is connected to the front planar panel 10, the rear section 111 is connected to the rear planar panel 12, and the lower section 112 is connected to the bottom panel 14.

[0036] The perforated plate 11 of this embodiment has a fold 113. When the foldable paper bag is in an upright position, the fold 113 extends vertically. A gap is maintained between the fold 113 and the portion of the perforations forming a vertical straight line (i.e., the first series of perforations 114A). The first straight line defined by the first series of perforations 114A does not intersect the fold 113.

[0037] In addition, the position or structure where the first, second and third straight lines meet on the perforated plate 11 also maintains a certain distance from the fold 113 .

[0038] The perforated plate 11 of this embodiment has notches 115 on the edge forming the opening 15 of the foldable paper bag 1. When the foldable paper bag 1 is in an upright position, the notches 115 align with the vertically arranged portion of the perforations (ie the first series of perforations 114A).

[0039] The notch 115 is a V-shaped cut in the edge of the perforated plate 11. Specifically, there is a unique V-shaped notch 115 on the edge of the perforated plate 11. This small cut creates a symmetrical indentation similar to the letter "V" characterized by two converging lines that meet at a point to form an acute angle pointing toward the perforation 114A to properly serve as a tear initiator.

[0040] In some embodiments, the foldable paper bag 1 is made of paper, and the paper is oriented in a long-grain manner. The fibers of the paper extend parallel to the longer dimensions of the perforated plates 11, 13 and the flat panels 10, 12.

[0041] In some embodiments, the perforated plate 11 has holes 116 formed on a vertical edge, and when the foldable paper bag 1 is in an upright position, the holes 116 are aligned with the non-vertically arranged portion of the perforations (i.e., the second series of perforations 114B). The perforated plate 11 has holes 117 formed on another vertical edge, and when the foldable paper bag 1 is in an upright position, the holes 117 are aligned with the non-vertically arranged portion of the perforations (i.e., the second series of perforations 114C).

[0042] In some embodiments, the hole 116 has a semicircular shape on the perforated plate 11, which butts against another semicircular hole formed on the flat plate 10. During die-cutting of the foldable paper bag 1, the two holes form a complete circle, which makes it easier to improve the manufacturing efficiency of the foldable paper bag 1, and when the user tears the perforated plate 11 along the second series of perforations 114B, the hole 116 can stop the tearing.

[0043] In some embodiments, the foldable paper bag 1 is made of paper having a basis weight of 80 g / m2. In some other embodiments, the basis weight of the paper ranges from 80 to 100 g / m2.

[0044] In some embodiments, the foldable paper bag 1 is made of kraft paper.

[0045] In some embodiments, the perforated plate 11 has a hole 118 formed between the perforations 114 and the opening 15. When the foldable paper bag is in an upright position, the hole 118 is aligned with the vertically arranged portion of the perforations (i.e., the first series of perforations 114A). Specifically, the hole 118 is located between the end of the first series of perforations 114A and the notch 115.

[0046] In some embodiments, the perforated plate 11 has a hole 119 , and the hole 119 is located at a position where the first, second and third straight lines meet. In other words, the first series of perforations 114A, the second series of perforations 114B and the third series of perforations 114C extend toward the hole 119 .

[0047] In this embodiment, the hole 119 is quadrilateral in shape, with the top corner aligned with the first series of perforations 114A. One of the side corners is aligned with the second series of perforations 114B, and the remaining side corners are aligned with the third series of perforations 114C. When a user tears the perforated plate 11 from one end of the first series of perforations 114A, the hole 119 can easily change the tearing direction.

[0048] In other words, when the through-holes 114 define an inverted "Y" shape, the holes 119 are located at the junction of the inverted "Y" shape.

[0049] In other words, the hole 119 is located where the front section 110 , the rear section 111 , and the lower section 112 meet.

[0050] In the above embodiment, the perforations are a plurality of small holes in the surface of the foldable paper bag 1. The upright position of the foldable paper bag 1 means that the foldable paper bag 1 stands upright with the opening 15 facing upwards and the bottom panel 14 acting as a base that touches the floor or table on which the foldable paper bag 1 is placed.

[0051] In the above-described embodiment, the perforations 114 are configured to be torn along their arrangement, and the straight line defined by the perforations 114 intersects the fold no more than once on each perforated sheet.

[0052] Figure 9 One of the states is shown when the perforation is torn and the foldable paper bag 1 can be opened. The planar panels 10, 12 can be folded inwards from the ends near the opening 15 of the foldable paper bag 1. Figure 10 Another state is shown when the perforations are torn and the foldable paper bag 1 is unfolded. The foldable paper bag provides a wide and suitable surface for users to place their food or groceries, and provides compartments to hold any sauces, fried foods, finger foods or granular materials such as salt or sugar.
