Description
Technical Field
[0001] This utility model relates to a storage bag for storing items, particularly a storage bag with multiple uses and capable of covering books. Background Technology
[0002] Modern people carry many personal items (such as mobile phones, wallets, and keys), and usually need to use bags to store these items for easy carrying. Most bags are typically a pouch-like body with an opening sealed by a zipper or buckle, which can be carried by hand or combined with shoulder straps of different designs such as back or crossbody.
[0003] Bags typically serve not only as storage devices but also as accessories for clothing. However, current technology often limits the ways bags can be used, such as changing a clutch bag to a crossbody bag. This necessitates purchasing multiple different styles of bags to offer more styling options, which can be quite expensive. Utility Model Content
[0004] This utility model's storage bag is multi-functional, offering various usage options and more diverse application possibilities.
[0005] The storage bag of this utility model includes a single piece, a zipper, a first fastener, and a second fastener. The single piece has a fold line, a first surface, a second surface, a first end, and a second end. The fold line is located in the middle of the single piece, dividing the single piece into the first surface and the second surface. The first end and the second end are located at the two ends of the fold line. The zipper has two fabric strips, two zipper teeth, at least one bottom stop, and at least one slider. The fabric strips are located inside the sheet, with one strip positioned outside the first surface and the other outside the second surface. The two ends of one strip engage with the two ends of the other strip, forming a first strip end and a second strip end. The first strip end is located inside the sheet corresponding to the first end, and the second strip end is located inside the sheet corresponding to the second end. The zipper teeth are located outside the fabric strips and form the bottom stop at either the first or second strip end. The slider is positioned between the zipper teeth to engage them, thus joining the outer edges of the first and second surfaces. A first fastener is fixed to the first end. A second fastener is fixed to the second end and can be fixed to the first fastener.
[0006] In a preferred embodiment, a first interlayer surface is provided on the inner side of the first surface, and a first outer interlayer is formed between the first interlayer surface and the first surface.
[0007] In a preferred embodiment, a first interlayer inner surface is further provided on the inner side of the first interlayer surface, and a first inner interlayer is formed between the first interlayer inner surface and the first interlayer surface.
[0008] In a preferred embodiment, a second interlayer surface is provided on the inner side of the second surface, and a second outer interlayer is formed between the second interlayer surface and the second surface.
[0009] In a preferred embodiment, a second inner surface is further provided on the inner side of the second interlayer surface, and a second inner interlayer is formed between the second inner surface and the second interlayer surface.
[0010] In a preferred embodiment, the zipper is a double-ended zipper design. Two bottom stops and two sliders are provided. The bottom stops are formed at the ends of the first and second fabric strips, and the sliders are positioned between the zipper teeth for engaging the zipper teeth.
[0011] In a preferred embodiment, the first fastener is any one of a linear element, a ring element, a latch, a quick-release element, a fastener, or Velcro, or a combination thereof.

[0063] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0064] Please refer to Figures 1 and 2. Figure 1 is an exploded perspective view of the storage bag 10 of this utility model, and Figure 2 is a perspective view of the storage bag 10 of this utility model. As shown in the figures, in this embodiment, the storage bag 10 includes a sheet 20, a zipper 30, a first fastener 40, and a second fastener 50. The sheet 20 can be folded arbitrarily, and the edges of the sheet 20 are joined and sealed by the zipper 30, so that the interior of the sheet 20 forms a space that can be used for storage. Through various different combinations and fixing methods between the first fastener 40 and the second fastener 50, the sheet 20 can be fixed in different shapes, so that the storage bag 10 can present multiple usage states.
[0065] Regarding the sheet 20, in this embodiment, it is made of a soft material such as fabric (e.g., but not limited to: canvas, nylon, linen, etc.), leather, or other woven materials. It has a fold line 21, a first surface 22, a second surface 23, a first end 24, and a second end 25. The fold line 21 is located in the middle of the sheet 20, dividing it into the first surface 22 and the second surface 23. Folding the sheet 20 along the fold line 21 overlaps the first surface 22 and the second surface 23. The first end 24 and the second end 25 are located at opposite ends of the fold line 21. Please refer to Figures 3 and 4. Figure 3 is a partial cross-sectional view of the first surface 22 of the storage bag 10 of this utility model, and Figure 4 is a partial cross-sectional view of the second surface 23 of the storage bag 10 of this utility model. As shown in the figures, a first interlayer surface 221 is also provided on the inner side of the first surface 22, forming a first outer interlayer 222 between the first interlayer surface 221 and the first surface 22. A first interlayer inner surface 223 overlaps within the first interlayer surface 221, forming a first inner interlayer 224 between the first interlayer inner surface 223 and the first interlayer surface 221. A second interlayer surface 231 is also provided inside the second surface 23, forming a second outer interlayer 232 between the second interlayer surface 231 and the second surface 23. A second interlayer inner surface 233 overlaps within the second interlayer surface 231, forming a second inner interlayer 234 between the second interlayer inner surface 233 and the second interlayer surface 231.
[0066] Regarding the zipper 30, in this embodiment, it is a double-headed zipper design, which has two fabric strips 31, two zipper teeth 32, two bottom stops 33, and two sliders 34. The two fabric strips 31 are located inside the sheet 20, and one fabric strip 31 is sewn onto the outer edge of the first surface 22, and the other fabric strip 31 is sewn onto the outer edge of the second surface 23. The two ends of one fabric strip 31 are respectively joined with the two ends of the other fabric strip 31, forming a first fabric strip end 311 and a second fabric strip end 312. The joining method is, for example, but not limited to, sewing. The first fabric strip end 311 is located inside the sheet 20 corresponding to the first end 24, and the second fabric strip end 312 is located inside the sheet 20 corresponding to the second end 25. Two zipper teeth 32 are respectively disposed on the outer side of two fabric strips 31. The two zipper teeth 32 interlock and form two bottom stops 33 at the end of the first fabric strip 311 and the end of the second fabric strip 312. Two zipper heads 34 are also disposed between the two zipper teeth 32. The two zipper heads 34 are used to interlock the two zipper teeth 32. They can be pulled up from the two bottom stops 33 respectively, and the outer sides of the first surface 22 and the second surface 23 are then joined by the first end 24 and the second end 25.
[0067] It is worth mentioning that since the first fabric tape end 311 is located inside the sheet 20 corresponding to the first end 24, when using the zipper pull 34, the user only needs to hold the first fabric tape end 311 inside the sheet 20 with one hand, and pull the zipper pull 34 from the lower stop 33 adjacent to the first fabric tape end 311 with the other hand. This allows the user to smoothly join the outer edges of the first surface 22 and the second surface 23 starting from the first fabric tape end 311. This method first fixes the first fabric tape end 311, thus allowing the user to apply more force when pulling out the zipper pull 34. In addition, since the zipper 30 of this utility model is a double-headed zipper design, the zipper pull 34 located at the second fabric tape end 312 can also be used in the same way to join the outer edges of the first surface 22 and the second surface 23 starting from the second fabric tape end 312.
[0068] Regarding the first fastener 40, in this embodiment, the first fastener 40 is a linear element that also has a ring-shaped component. The linear element is wound into a ring-shaped segment 41, and a linear segment 42 extends from the end of the ring-shaped segment 41. The segment is, for example but not limited to, hemp thread, cotton thread, or nylon rope, etc., and one end is fixed to the first end 24. The fixing method is, for example but not limited to, sewing.
[0069] Regarding the second fastener 50, in this embodiment, the second fastener 50 is an annular element, which is formed by winding a thread into a ring. The thread is, for example but not limited to, hemp thread, cotton thread, or nylon rope, etc. One end of the second fastener 50 is fixed to the second end 25, and the fixing method is, for example but not limited to, sewing.
[0070] With the above structure, the storage bag 10 of this utility model can present multiple usage states, which are described one by one as follows:
[0071] A. The first usage configuration of the storage bag 10 is as a clutch. Please refer to Figure 5, which is a three-dimensional schematic diagram of the first usage configuration of the storage bag 10 of this utility model. As shown in the figure, in this usage configuration, the two zipper teeth 32 are engaged by the zipper pull 34, allowing the outer edges of the first surface 22 and the second surface 23 to join. In this way, a closable space R1 is formed on the inner side of the sheet 20. The space R1 is formed by the overlapping of the first surface 22 and the second surface 23, and is used to store items. The user can hold the outer side of the sheet 20 to carry the storage bag 10 with them. The first outer interlayer 222, the first inner interlayer 224, the second outer interlayer 232, and the second inner interlayer 234 (these interlayers are located inside the sheet 20 and are not shown in the figure, but can be seen in Figures 3 and 4) can be used as hidden pockets inside the storage bag 10.
[0072] B. The second usage configuration of the storage bag 10 is as a three-dimensional clutch. Please refer to Figures 6 and 7. Figure 6 is a three-dimensional schematic diagram of the second usage configuration of the storage bag 10, and Figure 7 is a three-dimensional schematic diagram of the second usage configuration of the storage bag 10 from another perspective. As shown in the figures, in this usage configuration, the two zipper teeth 32 are engaged by the zipper pull 34, allowing the outer edges of the first surface 22 and the second surface 23 to properly engage. This proper engagement may be complete or incomplete, leaving an opening (as shown in Figure 6). Next, a bottom surface F is created between the first end 24 and the second end 25, with the bottom surface F positioned relative to the opening. Next, the linear segment 42 is tied from the outside of the sheet 20 to the annular second fastener 50, while the annular segment 41 can be stored inside the sheet 20 when not in use. In this way, the outline of the bottom surface F can be fixed, so that a three-dimensional space R2 that can be closed is formed inside the sheet 20. The three-dimensional space R2 is composed of the bottom surface F, the first surface 22 and the second surface 23, which is used to store items. The user can hold the outside of the sheet 20 to carry the storage bag 10 with him. The first outer layer 222, the first inner layer 224, the second outer layer 232 and the second inner layer 234 (the above layers are located inside the sheet 20, not shown in the figure, but can be seen in the figures 3 and 4) can be used as a hidden pocket inside the storage bag 10.
[0073] C. The third usage configuration of the storage bag 10 is as a backpack. Please refer to Figure 8, which is a perspective view of the third usage configuration of the storage bag 10 of this utility model. As shown in the figure, in this usage configuration, a shoulder strap 60 can be attached to the annular segment 41 and the second fixing member 50, while the linear segment 42 can be stored inside the sheet body 20 when not in use. The shoulder strap 60 has two buckles at both ends, and the annular segment 41 and the second fixing member 50 can be fixed to the two buckles by binding or fastening. The user wears the shoulder strap 60 on their body to carry the storage bag 10.
[0074] D. The fourth usage configuration of the storage bag 10 is for storing book B. Please refer to Figure 9, which is a perspective view of the fourth usage configuration of the storage bag 10. As shown in the figure, in this usage configuration, the sheet 20 is unfolded, the cover B1 of book B is inserted into the first outer layer 222, and the back cover B2 of book B is inserted into the second outer layer 232. At this time, the sheet 20 can protect book B. The user can selectively engage the two zipper teeth 32, allowing the outer edges of the first surface 22 and the second surface 23 to join. In this way, book B can be sealed inside the sheet 20. In addition, the linear segment 42 can be used as a bookmark for book B.
[0075] E. In the fifth usage state, the ring-shaped second fixing member 50 can also be used as a hanging ring, which can hang the storage bag 10 on a hook.
[0076] It is worth noting that the first fastener 40 is not limited to a linear or ring-shaped element; it can also be a linear element, a ring-shaped element, a latch, a quick-release mechanism, a buckle, or Velcro, or a combination thereof. Similarly, the second fastener 50 is not limited to a ring-shaped element; it can also be a linear element, a latch, a quick-release mechanism, a buckle, or Velcro, or a combination thereof. As long as the first fastener 40 can be quickly detached from or secured to the second fastener 50, or both the first fastener 40 and the second fastener 50 can be quickly detached from or secured to the shoulder strap 60, they fall under the category of the first fastener 40 and the second fastener 50.
[0077] In summary, the storage bag provided by this utility model can present multiple usage states to achieve the purpose of using one bag for multiple purposes.
[0078] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
