TECHNICAL FIELD

[0001] The utility model relates to article storage technical field especially, relates to a kind of extensible and foldable storage bag. BACKGROUND

[0002] In the field of article storage, especially for the storage of bedding, traditional bedding storage bags have been widely used. These storage bags are usually made of cloth or other flexible materials and are designed to hold bedding such as bed sheets, blankets, and pillowcases for easy organization and storage. Users can fold or roll up these bedding items and place them in the storage bag, thereby maintaining a certain level of cleanliness in the home environment.

[0003] However, traditional bedding storage bags have some significant drawbacks in actual use. First, these storage bags are often difficult to compress effectively. Even if the bedding is folded relatively neatly, the storage bag itself often cannot be further compressed in size, resulting in low efficiency in the use of storage space. Second, traditional storage bags are cumbersome to open and close, especially when it is necessary to quickly take out or put in some bedding. Users often need to completely open the bag, which not only wastes time and effort but also can cause other items inside the bag to scatter. In addition, as modern living spaces become increasingly compact, people increasingly need a storage solution that can efficiently utilize space while being easy to operate. Traditional storage bags cannot meet all user needs in this regard, especially when it is difficult to conveniently take out and put in items without completely opening the bag, which brings great inconvenience to users and increases the frustration when organizing bedding. Therefore, a expandable and foldable storage bag is proposed. SUMMARY

[0004] The utility model aims at solving the problem that the existing storage bag is usually difficult to compress effectively, even if the bedding is folded relatively neatly, the storage bag itself often cannot be further compressed in size, resulting in low efficiency in the use of storage space, second, traditional storage bag is cumbersome to open and close, especially when it is necessary to quickly take out or put in some bedding, users often need to completely open the bag, which not only wastes time and effort but also can cause other items inside the bag to scatter, in addition, as modern living spaces become increasingly compact, people increasingly need a storage solution that can efficiently utilize space while being easy to operate, traditional storage bags cannot meet all user needs in this regard, especially when it is difficult to conveniently take out and put in items without completely opening the bag, which brings great inconvenience to users and increases the frustration when organizing bedding.

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] Embodiment 1: Refer to Figures 1-9 A storage bag, comprising a storage shell 1. The storage shell 1 specifically comprises a shell base 11, a shell wall 12 and a shell cover 13.

[0029] The shell base 11 serves as the bottom support structure of the storage bag and provides bottom support for the items stored in the storage shell 1. The outer side of the shell base 11 is integrally formed with the shell wall 12, and the shell wall 12 and the shell base 11 together constitute the main structure of the storage bag. The top of the shell wall 12 is provided with a plurality of shell covers 13, which together with the shell wall 12 and the shell base 11 form a closed sealed cavity 2 for storing items.

[0030] The shell cover 13 comprises a top cover and a surrounding edge, and the surrounding edge is integrally formed with one side of the top of the shell wall 12 to ensure the stability of the structure. An expansion zipper 131 is fixedly connected between the top of the surrounding edge and the four side walls of the top cover. The design of the expansion zipper 131 allows the user to open or close it as needed to expand or shrink the capacity of the storage bag. A sealing zipper 122 is fixedly connected between the bottom of the surrounding edge and the top of the shell wall 12. The sealing zipper 122 is used to close or open the sealed cavity 2 to ensure the safe storage of the items.

[0031] The inside of the shell base 11 is provided with a base layer 111 for supporting the items stored in the sealed cavity 2 to prevent the items from crushing the bottom of the storage bag due to gravity.

[0032] A vacuum valve 121 is fixedly connected to one side of the bottom of the shell wall 12. The design of the vacuum valve 121 allows the user to use an external vacuum pump or other air extraction equipment to extract excess air from the sealed cavity 2, thereby reducing the volume of the storage bag and saving storage space.

[0033] The present application can be used in the field of article storage, and can also be used in other fields applicable to the present application.

[0034] Embodiment 2: Reference Figures 1-9 On the basis of Embodiment 1, an expandable and foldable storage bag is applied to the field of article storage. In order to facilitate carrying, a plurality of handles are fixedly connected to the outer side of the shell wall 12. The design of these handles allows the user to easily lift or carry the storage bag, improving the convenience of use.

[0035] When it is necessary to expand the capacity of the storage bag, the user can operate as follows: first, pull open the expansion zipper 131 on the peripheral top of the shell cover 13; then, add other shell covers 13, and connect them to the expansion zipper 131 on the peripheral top of the initial shell cover 13 through the sealing zipper 122 on the peripheral bottom of the added shell cover 13. In this way, the capacity of the storage bag can be increased as needed to meet the storage needs of different sizes of articles.

[0036] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, within the technical scope disclosed by the present application, can make equivalent substitutions or changes to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
