Description

Technical Field

[0001] This invention relates to a portable storage device, and more particularly to a detachable storage bag that can be folded into shape from a flat sheet structure and magnetically attached to the back of an electronic device (such as a smartphone). Background Technology

[0002] With the rapid development of mobile communication technology, smartphones have become an indispensable tool in modern people's daily lives. Besides using their phones for communication, internet access, and entertainment, users also have a strong need to integrate their phones with important personal items (such as credit cards, transportation cards, small amounts of cash, access cards, etc.). To meet this need, various types of phone storage accessories have appeared on the market, directly fixed to the back of the phone with adhesive. However, these products have significant drawbacks, such as being difficult to remove or reuse once glued on, and adding permanent thickness to the phone. To improve integration, another previous technology was the integrated card slot phone case, which directly integrates the card slot into the protective case structure. However, this design lacks modularity and flexibility, forcing users to be bound to a specific phone case, unable to remove the extra volume caused by the card slot when the storage function is not needed. To solve the fixation problems of the aforementioned adhesive and integrated accessories, in recent years, with the popularization of magnetic technology, magnetic card holders that can magnetically attach to the back of the phone have appeared on the market. While such products offer a better modular user experience, they are essentially pre-formed rigid or semi-rigid containers whose structure cannot be altered or flattened, and which still occupy a certain amount of three-dimensional space when not in use.

[0003] On another technological development path, there are also accessories on the market that apply the folding principle, such as mobile phone stands that can be folded from sheet-like objects. However, this type of technology is mainly used to provide a "support" function. The structure formed after folding is usually open and not designed to provide a "storage space" with good coverage and security.

[0004] In conclusion, existing mobile phone storage accessories, whether adhesive, integrated, or magnetic, all suffer from the inability to simultaneously achieve "detachability," "lightweight portability," "structural deformability," and "storage security." Specifically, there is currently no product on the market that can be used as a secure magnetic storage bag when needed, and can also be completely unfolded into a flat sheet for easy storage when not in use, while ensuring structural stability and protection after folding through specific rigid and flexible areas.

[0005] Therefore, how to provide a novel storage bag structure that can be folded from a sheet including a non-flexible area and a flexible area, providing a safe storage space, and being easily attached to and detached from electronic devices such as mobile phones using magnets, and returning to a flat state for easy carrying when not in use, is an urgent problem to be solved in this field. Utility Model Content

[0006] In view of this, the applicant, having accumulated many years of experience in the relevant industry, has conceived and proposed a detachable storage bag that has the function of holding items.

[0007] This application relates to a detachable storage bag, the main feature of which is that it can be formed from a single, fully unfolded cross-shaped sheet structure through specific bending and combination into a three-dimensional structure with accommodating space. This storage bag can quickly switch between a flat, unfolded state and a three-dimensional accommodating state without the need for additional tools.

[0008] The sheet structure includes a central area and a first, second, third, and fourth peripheral area surrounding the central area. Each peripheral area is connected to the central area via a flexible portion. The second and fourth peripheral areas are symmetrically structured and serve as the side walls of the bag; the third peripheral area serves as the front wall; and the first peripheral area serves as the top cover.

[0009] To form a accommodating state, the second and fourth peripheral areas bend upwards and utilize their own secondary flexible portions to wrap around and conform to the sides of the third peripheral area like wings. This connection is achieved through a non-permanent fixing method. In a preferred embodiment, a coupling mechanism is provided in the second and fourth peripheral areas, and a positioning mechanism or embedded metal sheet is provided at the corresponding position in the third peripheral area. The structure is then fitted together by magnetic attraction to form a stable accommodating space. The first peripheral area (top cover) can also be closed magnetically.

[0010] A key technical feature of this application is that the flexible portion connecting the central area and the surrounding areas has a specific width (e.g., greater than 0.4 cm). This width design not only disperses stress to improve durability and provides clear folding guidance for the user, but also naturally forms the thickness of the storage bag after the structure is folded, reserving buffer space for the stored items.

[0011] In addition, this application may also include other extended functions. For example, an expansion piece may be provided in the central area to divide the internal space; or a support structure may be provided on the back of the central area so that it can be attached to mobile devices such as mobile phones and also function as a mobile phone stand.

[0012] In summary, this application provides a detachable storage bag that is structurally sound, intuitively assembled, lightweight, portable, and versatile through its unique sheet structure, flexible width design, and magnetic assembly method. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] The non-permanent fixing methods described in this application refer to fixing, connecting, joining, or linking two objects together using methods such as magnetism, Velcro, detachable snap-fit ​​mechanisms, or reusable adhesive, and allowing for the removal of the fixing, connection, joining, or linking of the two objects at any time. The permanent fixing methods described in this application refer to fixing, connecting, joining, or linking two objects together using methods such as non-reusable adhesive, sewing, or nailing.

[0031] The coupling described in this application refers to fixing, connecting, joining, or linking two objects together through the aforementioned non-permanent or permanent fixing methods. The magnetism described in this application includes permanent magnetism, non-permanent magnetism, or ferromagnetic properties. The magnetic force described in this application is the attractive force generated by magnetism. For example, the magnetic materials used in this application are, but are not limited to, magnets or metals or alloys such as iron, cobalt, and nickel.

[0032] Direct bonding, as described in this application, refers to the direct contact of the surfaces of two objects, which are approximately parallel to each other. Indirect bonding, as described in this application, refers to the situation where the surfaces of two objects are separated by other objects and cannot directly contact each other, but are adjacent to each other and are approximately parallel to each other.

[0033] Although the terms "first," "second," "third," etc., may be used herein to describe various components, parts, regions, or sections, these components, parts, regions, and / or sections should not be limited by these terms. These terms are used only to distinguish one component, part, region, or section from another component, part, region, layer, or section. Therefore, "first…" as used below may be interpreted as "second…" or "third…" without departing from the teachings of this document.

[0034] The term "sheet-like" as used in this specification refers to an object whose length, width, or diameter is much greater than its thickness, thus giving the object a flat, two-dimensional shape. However, the object still possesses a certain thickness.

[0035] The detachable storage bag disclosed in this application has multiple non-flexible portions and multiple flexible portions. The non-flexible portions are sheet-like and can be connected to each other by the flexible portions, allowing the non-flexible portions to be bent relative to each other. The detachable storage bag can be bent into an unfolded state and a storage state by these flexible portions. For example, the flexible portions of this application can be made of flexible materials such as artificial leather or polyurethane, while the non-flexible portions can be made of any material that is relatively difficult to bend by hand, such as acrylic, fiberglass board, PC board, cardboard, or metal, etc. The non-flexible portions can be covered with the aforementioned artificial leather or polyurethane material.

[0036] Please see Figures 1 to 2 . Figure 1 This is a schematic diagram of the back of the detachable storage bag involved in this application in an unfolded state. Figure 2 This is a front plan view of the detachable storage bag according to this application in an unfolded state. As shown, when fully unfolded, it presents a single piece structure that is roughly cross-shaped. This single piece structure can be made of multiple layers of composite materials, for example, by hot-pressing an outer layer of PU leather and an intermediate rigid or semi-rigid support layer (such as PC, PP sheet or high-density fiberboard) to balance appearance, structural strength and protection of the stored items.

[0037] The storage bag 100 includes a central area 10, a first peripheral area 20, a second peripheral area 30, a third peripheral area 40, and a fourth peripheral area 50. The first peripheral area 20, the second peripheral area 30, the third peripheral area 40, and the fourth peripheral area 50 surround the periphery of the central area 10. The second peripheral area 30, the third peripheral area 40, and the fourth peripheral area 50 each include at least one non-flexible portion 1. The first peripheral area 20, the second peripheral area 30, the third peripheral area 40, and the fourth peripheral area 50 are bendable relative to the central area 10 by means of flexible portions 2; that is, flexible portions 2 are provided between the first peripheral area 20 and the central area 10, between the second peripheral area 30 and the central area 10, between the third peripheral area 40 and the central area 10, and between the fourth peripheral area 50 and the central area 10. The first peripheral area 20 and the third peripheral area 40 are located on opposite sides of the central area 10, and the second peripheral area 30 and the fourth peripheral area 50 are located on opposite sides of the central area 10. The second peripheral area 30 and the fourth peripheral area 50 can be connected to the third peripheral area 40 via non-permanent fixing methods. The first peripheral area 20 can be connected to any one of the second peripheral area 30, the third peripheral area 40, or the fourth peripheral area 50 via non-permanent fixing methods to form a locked accommodating state (e.g., ...). Figure 6-7 ).

[0038] In some embodiments, the second peripheral region 30 and the fourth peripheral region 50 are structurally symmetrical, serving as sidewalls in this application embodiment. Taking the second peripheral region 30 as an example, it includes a non-flexible portion 32; or it includes a slightly flexible portion 31 and non-flexible portions 32 and 33. This design allows the second peripheral region 30 to bend like a wing and adapt to different thicknesses of stored items at different bending angles. Correspondingly, the fourth peripheral region 50 may include a non-flexible portion 52; or it may include a slightly flexible portion 51 and non-flexible portions 52 and 53. The non-flexible portions 32, 33, 52, or 53 have a coupling mechanism. In some embodiments, the non-flexible portions 32, 33, 52, or 53 are magnetic, serving as a coupling mechanism.

[0039] Figure 3-4 This illustrates an implementation where the second peripheral region 30 or the fourth peripheral region 50 fits into the third peripheral region 40. The two non-flexible portions 32 and 33 of the second peripheral region 30 are bent through the secondary flexible portion 31, such that each of the two non-flexible portions 32 and 33 individually fits into two sides of one side of the third peripheral region 40 (e.g., the front and back sides of the non-flexible portion 41). Simultaneously, the two non-flexible portions 52 and 53 of the fourth peripheral region 50 are bent through the secondary flexible portion 51, such that each of the two non-flexible portions 52 and 53 individually fits into two sides of the other side of the third peripheral region 40 (e.g., the front and back sides of the non-flexible portion 45), forming an accommodating space, such as... Figure 5 As shown.

[0040] If the second peripheral region 30 includes only one non-flexible portion 32 or the fourth peripheral region 50 includes only one non-flexible portion 52, the non-flexible portion 32 of the second peripheral region 30 is attached to one side of the third peripheral region 40 (such as the front or back of the non-flexible portion 41); at the same time, the non-flexible portion 52 of the fourth peripheral region 50 is attached to the other side of the third peripheral region 40 (such as the front and back of the non-flexible portion 45) to form an accommodating space.

[0041] In some embodiments, to form a stable accommodating space, the third peripheral region 40 can be coupled to the second peripheral region 30 and the fourth peripheral region 50 respectively through the coupling mechanism of the non-flexible portions 32, 33, 52, or 53, forming a mutually fitted state. In some embodiments, a positioning mechanism 46 is provided at each end of the third peripheral region 40, and the second peripheral region 30 and the fourth peripheral region 50 are each provided with at least one coupling mechanism 9 (such as Velcro, snap fastener, magnet, or a magnetic metal or alloy such as iron, cobalt, or nickel) that matches the size of the positioning mechanism 46. For example, when the non-flexible portions 32, 52 are fitted to the ends of the third peripheral region 40, the coupling mechanism 9 is aligned with and coupled to the positioning mechanism 46 respectively.

[0042] In one embodiment, a positioning mechanism 46 is provided at each end of the third peripheral region 40, and two coupling mechanisms 9 (such as Velcro, snap fasteners, magnets, or magnetic metals or alloys such as iron, cobalt, and nickel) matching the size of the positioning mechanism 46 are provided in the second peripheral region 30 and the fourth peripheral region 50, respectively. For example, when the two non-flexible portions 32 and 33 are individually attached to two sides of one side of the third peripheral region 40, the two coupling mechanisms 9 are respectively aligned with the positioning mechanism 46 and coupled together. The fourth peripheral region 50 is also attached to one side of the third peripheral region 40 in a similar manner. When the two non-flexible portions 52 and 53 are individually attached to two sides of one side of the third peripheral region 40, the two coupling mechanisms 9 are respectively aligned with the positioning mechanism 46 and coupled together, which will not be elaborated here. In some embodiments, the coupling mechanism 9 can be a magnetic material.

[0043] In some embodiments, the third peripheral area 40 is formed by three non-flexible curved portions 41, 43, 45 and two secondary flexible curved portions 42, 44 interlaced. Positioning mechanisms 46 are provided on the non-flexible curved portions 41, 45 located on both sides. In some embodiments, the positioning mechanism 46 can be a perforation. Here, the "perforation" does not necessarily refer to a through hole; it can be a thin metal sheet (such as an iron sheet or tinplate sheet) embedded in the interlayer at that location, with its surface completely covered by PU leather. This allows for strong attraction with the magnet while maintaining a smooth and aesthetically pleasing appearance. The coupling mechanism 9, due to the perforation, can directly adhere to each other, increasing the adhesion force of the two non-flexible curved portions 32, 33 or 52, 53. Furthermore, due to the shape matching, the coupling mechanism 9 can align and engage with the positioning mechanism 46, thereby increasing the stability of the second peripheral area 30 (or the fourth peripheral area 50) and the third peripheral area 40, improving the user experience.

[0044] In some embodiments, such as Figure 2 As shown, the third peripheral area 40 is provided with multiple receiving holes 5, which can be used to place a SIM card, a SIM card ejector tool, or other small items. The main function of the two secondary flexible portions 42 and 44 in the receiving state is to provide flexibility to the third peripheral area 40, especially when more items are placed in this embodiment. The two secondary flexible portions 42 and 44 provide ample space for bending buffering of the third peripheral area 40, allowing this embodiment to accommodate more items.

[0045] like Figure 6-7 As shown, in some embodiments, the first peripheral area 20 serves as a top cover, and a magnetic or other non-permanent fixing method may be built into one end of it so that it can be connected to any of the second peripheral area 30, the third peripheral area 40, or the fourth peripheral area 50 to form a stable top cover.

[0046] Please refer to this again. Figure 2While there are many other foldable mobile phone or mobile device support structures on the market, they all have a mechanism to support multiple non-flexible and multiple flexible portions relative to other non-flexible and flexible portions. However, the present application embodiment is characterized by the connection relationship between the multiple non-flexible and multiple flexible portions compared to the prior art. Additionally, the width h of the flexible portion 2 located between the first peripheral region 20, the second peripheral region 30, the third peripheral region 40, and the fourth peripheral region 50 and the central region 10 is greater than that of the secondary flexible portions located in the second peripheral region 30, the third peripheral region 40, or the fourth peripheral region 50. In one embodiment, the width h is greater than 0.4 cm. This width design offers several technical advantages: First, the wider bending zone disperses stress, effectively improving durability under repeated bending and preventing material fatigue fracture; second, it provides clearer visual and tactile guidance, allowing users to intuitively and easily fold along the correct path; third, when folded into its storage state, this width creates the "thickness" of the bag, naturally providing a buffer distance between the bottom and top of the storage space. These technical features endow the embodiments of this application with the function of accommodating items.

[0047] The central area 10 serves as the base of the storage bag 100. In this embodiment, it is mainly composed of at least one non-flexible portion 1 to provide support and flatness for the overall structure.

[0048] Please refer to Figure 8-10 In some embodiments, the central area is provided with an expansion tab 70, one end of which is connected to the central area 10. The expansion tab 70 has a receiving hole 5; a user can place card-shaped items into it. The main function of the expansion tab 70 is to divide the storage space of the bag 100 into two parts, facilitating the sorting of contents. Additionally, the user can also pull up the expansion tab 70, such as... Figure 10 As shown, the items stored inside are pulled out for easy access by the user.

[0049] Please refer to Figure 11 This is one of the usage state diagrams of the embodiments of this application. In some embodiments, the central area 10 may be provided with magnetic or other non-permanent fixing methods, so that the embodiments of this application can be coupled to a mobile device through the central area 10.

[0050] Please refer to Figure 12-14 In some embodiments, the central area 10 does not have a flexible portion 1, but a support structure 12 is provided on the back of the central area 10. In a preferred application, the support structure 12 includes an array of magnets or other non-permanent fixing methods. Thus, the bag 100 can be conveniently and securely attached to the back of a mobile device (such as a smartphone). In use, the user can not only place items in the embodiment of this application, but also fold the support structure 12 to form a shape such as... Figure 13 The supported state. After fixing the embodiment of this application to the mobile device, the mobile device is also supported on a flat surface, making it convenient for the user to view, such as... Figure 14 As shown.

[0051] In some embodiments, the storage bag 100 in this application embodiment can be integrally formed with the protective case or back cover of the mobile device. For example, the central area 10 can be the protective case or back cover of the mobile device. One end of the first peripheral area 20, the second peripheral area 30, the third peripheral area 40, and the fourth peripheral area 50 can be connected to the protective case or back cover of the mobile device, but can be folded relative to the protective case or back cover of the mobile device to form the accommodating space of the storage bag 100.

[0052] In some embodiments, the central area 10 is provided with an electronic location tracking mechanism. Users can track the location of the bag in this embodiment using a mobile device. Specifically, the electronic location tracking mechanism can be integrated with the non-flexible portion of the central area 10. The electronic location tracking mechanism may include an integrated circuit or a printed circuit board.

[0053] As described above, the folding and use of this application involves transforming a completely flat piece into a three-dimensional, stable, and secure storage bag through a few simple bending steps, without requiring any additional tools or complicated operations.

[0054] In summary, this application creates a novel form of storage bag through ingenious area division (flexible / non-flexible) and non-permanent fixing method (magnetic). The core advantages of this invention are that it can be laid flat, folded, magnetically attached, structurally stable, and functionally versatile. This invention is not limited to the above embodiments; its materials, the specific shapes of each area, the number and layout of magnets, and the form of the receiving holes can all be varied and combined within the spirit of this invention.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Therefore, any equivalent changes and modifications made without departing from the spirit and scope of this application should be covered within the patent scope of this application.
