Description

Technical Field

[0001] This utility model relates to the field of storage bag technology, and more specifically, to a handle-type storage bag. Background Technology

[0002] Storage bags are mainly used to store daily necessities and personal items such as clothes and quilts. Storage bags can be classified by material into PE storage bags, non-woven storage bags, and cotton bags. As for their uses, there are many different types, including miscellaneous bags, clothing storage bags, underwear and sock storage bags, small item storage bags, car accessory storage bags, jewelry bags, and bead bags. Among them, PE storage bags are further divided into regular storage bags and compression storage bags, while cotton bags include patterned cloth bags and cotton-lined bags.

[0003] Currently, the following technical defects exist in the practical application of portable storage bags on the market: First, the structural design of the storage bags is unreasonable. Most adopt a single-layer outer packaging structure. This structure makes it easy for the items stored inside to collide and shift during transportation due to the lack of effective separation and fixing measures. This results in items being messy and disorderly, making it difficult to maintain the cleanliness of the inside of the storage bag and failing to meet users' needs for neat and organized storage. Second, the materials of the storage bags are limited. Existing portable storage bags are mostly made of cotton or non-woven fabric. These materials are soft and lack sufficient structural support. When taking out or putting in items, users often need to support the bag with one hand and operate it with the other hand. This is not only cumbersome and affects the efficiency of use, but also, when there are many or heavy items, the soft bag is prone to deformation and collapse, further increasing the difficulty of taking out or putting in items and causing many inconveniences for users.

[0004] In summary, existing hand-held storage bags have technical problems such as difficulty in maintaining the neatness and order of internal items and difficulty in providing effective structural support, and urgently need to be improved. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a handle-type storage bag, which has the following beneficial effects:

[0017] 1. This type of tote storage bag, through the design of an outer sealing layer, a second zipper, a connecting layer, a third zipper, and a dividing layer, enables the tote storage bag to facilitate classification and organization. The outer sealing layer and the second zipper work together to directly divide the two main parts of the bag during use. The connecting layer and the dividing layer connect the two sides of the dividing layer to the inside of the connecting layer via the third zipper, dividing the interior of the bag into multiple storage spaces for orderly storage of items, thus achieving the purpose of convenient classification and organization.

[0018] 2. This type of hand-held storage bag, through the design of a supporting airbag column, an elastic airbag, an air inlet, a one-way valve, and an exhaust valve, provides convenient support for the bag's structure. The coordinated design of the elastic airbag, air inlet, one-way valve, and exhaust valve allows for repeated compression of the elastic airbag during use, inflating the supporting airbag column to form a support structure. This facilitates the placement and removal of items. Furthermore, the supporting airbag column provides excellent cushioning, offering better protection for items inside the bag. The exhaust valve and sealing cap allow for the release of air from the supporting airbag column when not in use, saving space and achieving the goal of conveniently supporting the bag's structure.

[0028] Please see Figures 3-4 A tote bag includes two symmetrically arranged bag bodies 1, which are fixedly connected at their lower sides. The edges of the two bag bodies 1 are detachably connected via a first zipper 5. A reinforcing strip 2 is sewn onto the outer surface of each bag body 1, with a handle 3 at the upper end of the reinforcing strip 2. An outer side pocket 4 is sewn onto the inner side of the reinforcing strip 2 on the outer surface of each bag body 1. A first zipper 5 is located at the inner edge of each bag body 1. The wall is provided with an outer sealing layer 6, which is detachably connected to the inner wall of the storage bag body 1 via a second zipper 7. The lower side of the outer sealing layer 6 is fixedly connected to the inner bottom wall of the storage bag body 1. The edge of the outer sealing layer 6 is provided with a second zipper 7. The inner wall of the storage bag body 1 is fixedly connected with a connecting layer 8. One side of the connecting layer 8 is detachably connected to both sides of the dividing layer 10 via a third zipper 9. There are two connecting layers 8 and two dividing layers 10. The inner wall of the storage bag body 1 is fixedly connected with a dividing layer 10.

[0029] Specifically, by opening the two symmetrically arranged storage bag bodies 1 and unzipping the first zipper 5, the outer sealing layer 6 and the second zipper 7 are used to separate the contents of the two storage bag bodies 1 according to the type of items to be stored. If the storage bag is to be divided into two larger areas, the second zipper 7 can be unzipped to separate the contents of the two storage bag bodies 1. Then, for the classification and storage of smaller items, the connecting layer 8 and the dividing layer 10 are used. The third zipper 9 on both sides of the dividing layer 10 is connected to the connecting layer 8. For example, clothing can be placed in one space separated by the dividing layer 10 and the connecting layer 8, and small items can be placed in another space. In this way, the interior of the storage bag body 1 can be divided into multiple storage spaces, so as to store items in an orderly manner and achieve the purpose of facilitating the classification and organization of items.

[0030] Please see Figures 1-5A support airbag column 11 is fixedly connected to the outer surface of the storage bag body 1. The support airbag column 11 is located at the outer corner of the two storage bag bodies 1. The support airbag columns 11 on the outer sides of the two storage bag bodies 1 are connected to each other on the lower surface of the storage bag body 1. An elastic airbag 12 is fixedly connected to the upper surface of the storage bag body 1. An air inlet 13 is provided on one side of the elastic airbag 12. A one-way valve 14 is provided on the other side of the elastic airbag 12. An exhaust valve 15 is fixedly connected to one end of the one-way valve 14. A one-way valve 14 is provided inside the air inlet 13. One end of the exhaust valve 15 is connected to the interior of the support airbag column 11. A sealing cap 16 is threadedly connected to the outer surface of the exhaust valve 15.

[0031] Specifically, before using the storage bag, ensure that the sealing cap 16 is tightly screwed onto the exhaust valve 15. Repeatedly compress the elastic airbag 12. Air inside the elastic airbag 12, under the action of the one-way valve 14 at the air inlet 13, can only enter and pass sequentially through the one-way valve 14 and the exhaust valve 15, thus filling the support airbag column 11. With continuous compression, the support airbag column 11 continuously expands, forming a stable support structure at the outer corners of the storage bag body 1. For example, when storing a large amount of heavy clothing or large items, the support airbag column 11 can effectively prevent the storage bag from collapsing due to pressure build-up. The airbag deforms and collapses under stress, greatly facilitating the handling of items with one or both hands. When the storage bag is subjected to external impact, the supporting airbag column 11 can provide good cushioning due to its elasticity, thereby protecting the items inside the storage bag body 1. When the storage bag is no longer in use and needs to be stored, the sealing cap 16 can be unscrewed from the exhaust valve 15, and the supporting airbag column 11 can be squeezed. The gas inside will then be discharged through the exhaust valve 15, which reduces the volume of the storage bag, saves storage space, and thus facilitates the support of the storage bag structure.

[0032] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
