Description

This invention relates to a bag for storing items. Conventionally, tote bags with an open top and handles are known (see, for example, Patent Document 1). With this type of tote bag, the user can easily put in and take out items because they can always access the interior (storage space) directly.

The embodiments of the present invention will be described below with reference to the attached drawings. Note that the following embodiments are merely examples of the present invention and do not limit the technical scope of the present invention. [Bag 10] The bag 10 according to this embodiment is an example of a bag of the present invention. The bags of the present invention include various types of bags, such as tote bags, handbags, and bags without handles. In this embodiment, a shoulder-type (shoulder-carryable) tote bag with a handle (shoulder strap) will be used as an example for explanation. [Embodiment 1] Figure 1 is an external perspective view showing the overall configuration of the bag 10 according to Embodiment 1. Figure 2 is a front view of the bag 10, Figure 3 is a rear view of the bag 10, Figure 4 is a left side view of the bag 10, Figure 5 is a right side view of the bag 10, Figure 6 is a top view of the bag 10, and Figure 7 is a bottom view of the bag 10. The bag 10 comprises a bag body 1 and a handle 2. The bag body 1 comprises a bottom 13, a front part 11 that rises upward from the bottom 13 on the front side, and a rear part 12 that rises upward from the bottom 13 on the rear side, and has an opening 14 (see Figures 1 and 6) at the top. The bag body 1 is formed into a bag shape by, for example, folding a single long, rectangular piece of fabric in half and sewing the side edges together. In Figures 1, 4, and 5, reference numeral 1L indicates the left side seam where the front side (corresponding to the front part 11) and the back side (corresponding to the rear part 12) of the fabric are sewn together, and reference numeral 1R indicates the right side seam where the front side (corresponding to the front part 11) and the back side (corresponding to the rear part 12) of the fabric are sewn together. Various materials such as natural fibers, chemical fibers, and synthetic fibers can be used for the fabric of the bag body 1. The bottom portion 13 is provided with a rectangular gusset having a predetermined width in the front-to-back direction. The gusset is formed, for example, by folding and sewing the side edges of the central portion of the fabric (see Figure 7). The bag 10 is able to stand on its own due to the gusset. The method of manufacturing the bag body 1 is not limited to the above method, and may also be done by joining together multiple pieces of fabric, for example. The bottom portion 13 has a width of approximately 300 mm in the left-to-right direction and a width of approximately 100 mm in the front-to-back direction. Note that the size of the bottom portion 13 is not limited to this and can be appropriately determined
