The first fastening member5and the second fastening member4are selected from snap joint, bonding joint, velcro, zip or their combination. The connection relationship between the first fastening member5and second fastening member4is flexible, for example, it can be fixed on the storage device when using, or removed when not using, the specific connecting method could be fixed and non-removable, or removable. Based on the needs, the fastening member may also be disposed on the third axial directions of the storage device.

The present invention also provides a bag which the foresaid storage device is folded along the first folding auxiliary structure2, as shown inFIG. 3; or the bag is formed by connecting two storage devices via the fastening members, as shown inFIG. 4.

The bag shown inFIG. 3is a storage device folded along the first folding auxiliary structure2. Specifically, by folding along the first folding auxiliary structure2, the multiple storage chambers1are separated into two. The storage chambers1on the left of the first folding auxiliary structure2being the cover, while the storage chambers on the right of the first folding auxiliary structure2being the bottom (the cover and bottom parts are symmetrical and can be interchanged). The first fastening members5on the left and right edge of another storage device are used to fasten the bottom and cover parts, so as to form a bag. The first fastening members5can form a closed structure after fastening, and may also be non-closed structure, such closed or non-closed structure can be used as handle, user can conveniently move such bag by lifting or pulling such closed or non-closed structure. The first fastening member5can be a snap joint, a bonding joint, a velcro, a zip and their combination.

When in use, since the material of the storage device is relatively soft, by opening the bag cover on top of the corresponding storage chamber, the fastening member adjacent to the storage chamber1is also opened. Putting stuff in the corresponding storage chamber1does not require the opening of the fastening member of other nearby storage chambers, which means the user does not need to open the bag cover on top of other storage chambers. The users only need to open or fasten the corresponding fastening member when picking or putting stuff, rather than opening or fastening the entire bag cover. This bag therefore provides convenience in accessing the storage chamber.

When the aforesaid bag has two storage devices that are fastened in multiple first fastening members5, there can be two implementation examples.

The first example, as shown inFIG. 4, is specifically uses two storage devices to join the corresponding first fastening member5to fasten and fix the two storage devices, one storage device will be the cover and the other storage device will be the bottom, thus the second fastening member4will serve as the handle of bag, so as to form a bag. The first fastening member5can be a snap joint, a bonding joint, a velcro, or a zip or a combination thereof. The second fastening member4is a handle structure.

When in use, since the material of the storage device is relatively soft, by opening the bag cover on top of the corresponding storage chamber, the fastening member adjacent to the storage chamber1is also opened. Putting stuff in the corresponding storage chamber1does not require the opening of the fastening member of other nearby storage chambers, which means the user does not need to open the bag cover on top of other storage chambers. The users only need to open or fasten the corresponding fastening member when picking or putting stuff, rather than opening or fastening the entire bag cover. This bag therefore provides convenience in accessing the storage chamber.

Another specific function is to use a partition6, connecting the two storage devices symmetrical and closed to the partition respectively, as shown inFIG. 5. Using the first fastening member5to fasten and fix each storage device onto the partition6. One of the storage devices is the cover part and the other storage device is the bottom part, so as to form a bag. The first fastening member5can be a snap joint, a bonding joint, a velcro, and zip or a combination thereof. The second fastening member4is in handle structure.

When in use, since the material of the storage device is relatively soft, by opening the bag cover on top of the corresponding storage chamber, the fastening member adjacent to the storage chamber1is also opened. Putting stuff in the corresponding storage chamber1does not require the opening of the fastening member of other nearby storage chambers, which means the user does not need to open the bag cover on top of other storage chambers. The users only need to open or fasten the corresponding fastening member when picking or putting stuff, rather than opening or fastening the entire bag cover. This bag therefore provides convenience in accessing the storage chamber.

Preferably, the cover of the bag has the storage optimization pouch7which is used for integrating with the storage chamber, as shown inFIG. 6. In order to optimize the use of the storage chamber1, a storage optimization pouch7is disposed inside the cover part of the bag to integrate with the storage chamber. The storage optimization pouch7can be built to match the shape of the storage chamber1. It can be fit into the storage chamber1. Firstly put the stuff in the storage optimization pouch7, and then put the storage optimization pouch7in the storage chamber1.

When in use, since the material of the storage device is relatively soft, by opening the bag cover on top of the corresponding storage chamber, the fastening member adjacent to the storage chamber1is also opened. Putting stuff inside the storage optimization pouch7in the corresponding storage chamber1does not require the opening of the fastening member of other nearby storage chambers, which means the user does not need to open the bag cover on top of other storage chambers as well as other storage optimization pouch7. The users only need to open or fasten the corresponding fastening member when picking or putting stuff, rather than opening or fastening the entire bag cover. This bag therefore provides convenience in accessing the storage chamber.

Preferably, in order to better use the storage device, and prevent the storage device to waggle at the bottom or inside of the bag, and affect the fixation of stuff, the fixation structure is provided on the inside of the bag that integrates with the storage device. The fixed structure can be a snap joint, a bonding joint, a velcro, and zip or their combination. The fixed structure is used to fix the storage optimization pouch7onto the inside of the storage device or other positions inside the bag.

Preferably, in order to better use the storage device, a buffer layer is provided in the cover of the bag that integrates the storage chamber or the storage optimization pouch7. In case of external force, the buffer layer in between the storage chamber and the storage optimization pouch7will protect the stuff in the storage chamber and storage optimization pouch7from damage.

Besides, the bag provided in the implementation example of the present invention could also be embedded in the ordinary bags on the market as the outer accessory of the existing bags in the market, so as to become an outer device that optimizes the bags in the market. Specifically, the boundary dimension of the storage device should correspond to the outer dimension of the bag. When in use, install the storage device outside the bag, to put stuff inside the storage device, the user shall base on the size of stuff to open the corresponding bag cover on the storage chamber1, and put the stuff in the corresponding storage chamber1.

Because the storage device or storage chamber have relatively fixed position, and its material is relatively soft, user doesn't need to open the entire bag cover for picking and putting stuff but only needs to open part of the bag cover. Specifically, opening the corresponding fastening member will allow the user to access the corresponding storage chamber. The users only need to open or fasten the corresponding fastening member when picking or putting stuff, rather than opening or fastening the entire bag cover. This bag therefore provides convenience in accessing the storage chamber.

The material structure newly provided by the present invention has the features of waterproof, light weight, proper hardness, capability to fold, high wearing feature, scratch resistant. The storing spatial pattern of the said storage device could be adjusted when needed; it could effectively protect the stored items. The provided bag could be opened partially, allowing quickly and conveniently access to the stored items, the storage space in the bag is designed for a better protection of stored items.
