[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0019] FIG. 1 shows a packaging bag according to one embodiment of the present invention. The packaging bag 100 includes a bag member 110 and a handle member 120 attached to the bag member 110. In the example shown in FIG. 1, contents such as protein powder are contained inside the bag member 110. By inserting a finger into an opening region 121 of the handle member 120 attached to the bag member 110 and gripping the handle member 120, a purchaser can take the product home without placing the bag member 110 in a plastic bag. The bag member 110 is provided with a slit 111 for opening as needed. Furthermore, the handle member 120 is provided with a first perforation 122-1 and a second perforation 122-2 for separating the upper portion of the handle member 120.

[0020] In this specification, the term "product" primarily refers to the bag member 110 containing the contents, but may also refer to the contents themselves, or to the packaging bag 100 in which the handle member 120 is attached to the bag member 110 containing the contents. The term "product" may also refer to the packaging bag 100 in which the handle member 120 is attached to the bag member 110 in which no contents are contained.

[0021] 2A to 2G show a handle member according to one embodiment of the present invention. 2A, 2B, 2C, 2D, 2E, 2F, and 2G are a front view, a back view, a plan view, a bottom view, a right side view, a left side view, and a perspective view of the handle member 120 alone, respectively. The handle member 120 is folded along a folding line 123 and can be attached to the bag member 110 with an adhesive member 124 such as double-sided tape. The adhesive member is preferably provided on both the front and back sides of the bag member 110, but in FIGS. 2A to 2G, only one side is labeled. The handle member 120 may be attached to the bag member 110 by a method other than adhesion.

[0022] FIG. 3 shows a reference cross-sectional view taken along line AA in FIG. 1. The bag member 110 has a zipper 112 that allows the top end to be repeatedly closed even after opening. To open the bag member 110, a portion of the handle member 120 located between the first perforation 122-1 and the second perforation 122-2 is cut away along these perforations, and a portion between the perforations on the back side is similarly cut away. FIG. 4A shows the state in which a portion of the handle member between the perforations has been cut away. Then, the zipper 112 can be opened by cutting away the upper portion of the bag member 110 from a slit 111 provided in the bag member 110 as needed. FIG. 4B shows the state in which the upper portion of the bag member has been cut away.

[0023] In this specification, the "upper portion" of the bag member 110 refers to at least a portion of the portion of the bag member 110 above the zipper 120 when a consumer grasps the product using the handle member 120, in other words, at least a portion of the portion between the zipper 120 and one end 110-1 of the bag member 110 to which the handle member 120 is attached. Furthermore, in this specification, the "upper portion" of the handle member 120 refers to at least a portion of the portion above the first perforation 122-1 or the second perforation 122-2 of the handle member 120 when a consumer grips a product using the handle member 120, in other words, at least a portion of the portion located in the direction of the one end 110-1 from the first perforation 122-1 or the second perforation 122-2, and the "lower portion" of the handle member 120 refers to at least a portion of the portion below the first perforation 122-1 or the second perforation 122-2 of the handle member 120 when a consumer grips a product using the handle member 120, in other words, at least a portion of the portion located in the direction of the other end 110-2 opposite the one end 110-1 from the first perforation 122-1 or the second perforation 122-2.

[0024] At least one of the first perforation 122-1 and the second perforation 122-2 of the handle member 120 is provided above the zipper 112 along the extension direction of the zipper 112. By arranging at least the first perforation 122-1, which is the upper perforation of the two perforations, above the zipper 112 in a front view of the packaging bag 100, it becomes possible to easily cut off the upper portion of the bag member 110 above the zipper 112 and open the bag member 110 when a portion between these perforations is cut off.

[0025] The handle member 120 is manufactured separately from the bag member 110 and attached to the bag member 110. The handle member 120 is preferably manufactured using a resource other than petroleum. The handle member 120 can be attached to a wide variety of bag members having a zipper, allowing the bag member to be carried without being placed in a plastic bag. If the handle member 120 does not contain or is substantially free of plastic, this not only reduces the amount of plastic bags used, but also further reduces the amount of petroleum used in plastic production. It is also preferable that the bag member 110 does not contain or is substantially free of plastic except for the zipper. Examples of materials made from resources other than petroleum include LIMEX (registered trademark), recycled paper, cellulose nanofiber, etc. The packaging bag 100 of the present invention can reduce the amount of plastic bags used due to its structure, and at least one of the bag member 110 and the handle member 120 may contain plastic as a material. When plastic is included as a material, it is preferable to use plastics that have a relatively small environmental impact, such as biodegradable plastics and biomass plastics.

[0026] 4B , which shows a state in which a portion of the handle member 120 between the perforations and an upper portion of the bag member 110 above the zipper 112 have been separated, in this openable state, a lower portion 120B of the handle member 120 below the first perforation 122-1 or the second perforation 122-2 remains attached to the bag member 110. As an example, by coloring the lower portion 120B of the handle member 120 in a color that corresponds to the contents of the bag member 110, a consumer who has purchased and opened the product can visually distinguish the contents.

[0027] Furthermore, by printing a two-dimensional code corresponding to the contents on lower portion 120B, consumers can read the two-dimensional code with a mobile device such as a smartphone as needed to obtain information about the contents. For example, if the contents are protein, a two-dimensional code representing the content of protein, fat, carbohydrates, etc. per specified number of grams or the URL of a web page displaying the number of calories per specified number of grams can be printed on lower portion 120B. Here, printing includes printing on a member separate from handle member 120 and attaching that member to handle member 120.

[0028] 5A to 5F show a packaging bag according to one embodiment of the present invention. Figures 5A, 5B, 5C, 5D, 5E, and 5F are a front view, a back view, a plan view, a bottom view, a right side view, and a left side view of the packaging bag 100, respectively.

[0029] In FIG. 5A, the shape of the handle member 120 is represented by solid lines, and the shapes of other parts are represented by dotted lines. This is intended to emphasize the appearance of the handle member 120; other parts may also be represented by solid lines as their actual visible shapes. Furthermore, the dashed-dotted lines around the left and right ends of the first perforation 122-1 and the second perforation 122-2 on the handle member 120 indicate that the tab or protruding part located on the left end may be located on the right end, or may be located on both ends. These dashed-dotted lines can be understood as lines that represent only the boundary between the part to be emphasized in appearance and the remaining parts. When viewing the packaging bag 100 as a design, the dashed-dotted lines can be understood as lines that represent only the boundary between the part for which a partial design registration is sought and the remaining parts. In the drawings from FIG. 2A onward, all lines are represented by solid lines; however, depending on the part to be emphasized, any of the solid lines may be represented by dotted lines. The lines representing the first perforation 122-1 and the second perforation 122-2 represent the shape of the perforations and are not dotted lines.

[0030] In the rear view of Fig. 5B, there are cross marks 113 on the bottom right and bottom left of the handle member 120. In Fig. 5B, only one of the marks is labeled. When attaching the handle member 120, by aligning the bottom right and bottom left of the handle member 120 with the marks on the bag member 110, the perforations of the handle member 120 can be appropriately positioned with respect to the zipper 112 of the bag member 110. Here, printing includes printing on a member separate from the bag member 110 and attaching the member to the handle member 110. [Explanation of symbols]
