Abstract
Description
[Technical Field]
[0001] This invention relates to a bag whose design can be changed using a zipper attached to the main body. [Background technology]
[0002] Each bag has a specific design and material, and these cannot be changed. Therefore, users need to own multiple bags with different colors, patterns, and materials to use depending on their mood and purpose. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] [Non-patent literature]
[0004] [Non-Patent Document 1] Summary of the Invention [Problem to be solved by the invention]
[0005] Typically, a bag has a single design and cannot be changed, so if a user wants to increase the variety of designs, they need to own bags with different designs. Also, if a user owns bags with different colors, patterns, and materials according to their preferences and needs, it is a purchase burden for each bag and requires storage space. Therefore, the bag of this invention allows users to have a variety of designs in one bag, solving the aforementioned issues of design variety, financial burden, and storage space. [Means for solving the problem]
[0006] In this invention, the upper and lower parts of the bag-shaped bag are made separately, and matching zippers of the same standard are sewn to the bottom edge of the upper and lower parts, respectively. The zippers are made of a pair of separate parts, each with a separate pin and a flip pin. When attaching the pin part to the upper part of the bag, the flip pin part is attached to the lower part of the bag. The reverse combination is also possible as long as the zippers are paired. This structure allows for the free combination of upper and lower parts of the same size, as long as they are equipped with the same standard and zipper on the same side. The lower part is primarily made in a variety of colors, patterns, and materials. The upper part can also be made in a variety of colors, patterns, and materials, and by adding handles or reversible outer or inner linings, the design and uses can be further diversified. [Effects of the Invention]
[0007] As mentioned above, the bag of this invention can be changed to a variety of designs, so one bag can accommodate the user's needs, preferences, and moods. In addition, the design can be changed by simply replacing the top or bottom of the bag, which reduces the owner's financial burden and allows for more compact storage space than having to carry multiple bags. [Brief explanation of the drawings]
[0008] [Figure 1] 1 is a view showing the upper and lower parts of the bag connected together; FIG. [Figure 2] FIG. 2 is a view showing the upper and lower parts of the bag of the present invention separated. [Figure 3] This is a diagram of the bag of the present invention with a shoulder strap attached to the top. [Figure 4] This is a diagram of the bag of the present invention with an outer fabric attached to the top, making it reversible. DETAILED DESCRIPTION OF THE INVENTION
[0009] The cylindrical upper body and the bag-like lower body are made separately so that the bag will have a bag-like shape when connected. The lower body is made the same size as the upper body and in a variety of colors, patterns, and materials. One side of a zipper (the box pin side or the butterfly pin side) is sewn to surround the bottom opening of the upper body (whether it is inside or outside), and the mating side of the zipper (the side different from the one attached to the upper body) is sewn to the top opening of the lower body, making it possible to connect and detach the upper and lower bodies via the zipper.
[0010] The upper part of the bag can also be modified in a variety of designs, as long as the zipper sewn to the lower part is the same size as the one sewn to the opening at the bottom. In addition to different colors, patterns, and materials, the upper part can be made with handles that can be used as a tote bag or shoulder bag, or with a reversible structure that can be made with different outer or inner linings, increasing the variety of designs and uses. [Example]
[0011] An example will be explained below with reference to the attached drawings. The zipper 5 sewn to the bottom of the upper part of the main body of 1 is paired with the zipper 6 at the top of the lower part of the main body of 2, and they can be connected as shown in 4. Furthermore, by opening this zipper, the lower part of the main body of 2 can be removed. The lower part of the main body of 2 can be replaced with the upper part of the main body of 1 if it is the same size and has a zipper of the same standard that is paired with the zipper on the upper part of the main body of 5, as shown in 6.
[0012] As a variation of the design of the top of the main body of 1, if there are handles that can be used as a tote bag like 3 or a shoulder bag like 7, and in addition, even if there are cases like 8 and 9 where the outer or inner lining is attached and the bag has a reversible structure, the method of changing the top and bottom parts of the bag remains the same as long as the structure allows the top and bottom parts of the bag to be changed via a zipper.
