[0029] Please refer to Figures 1 to 3 , as shown in the figure, an embodiment of the present application discloses a multifunctional storage bag. The multifunctional storage bag includes a first outer bag layer 1 and a second outer bag layer 2 that overlap each other, and an intermediate bag layer 3 is sandwiched between the first outer bag layer 1 and the second outer bag layer 2; a bag opening 11 is provided on one side of the three overlapping bag layers, and a sealing member 4 is provided at the bag opening 11; a sealing edge 5 is provided on the side edge of the three overlapping bag layers where the bag opening 11 is not provided for sealing; sealing edges 5 are provided on the side edges of both the first outer bag layer 1 and the intermediate bag layer 3 for sealing, and both the first outer bag layer 1 and the intermediate bag layer 3 are airtight bag layers prepared from airtight materials; a switching valve 6 is provided on the outer side surface of the first outer bag layer 1, and the inner air inlet through hole of the switching valve 6 communicates with the closed cavity formed by the closed connection of the first outer bag layer 1 and the intermediate bag layer 3; a receiving cavity 71 formed between the second outer bag layer 2 and the intermediate bag layer 3 is used to receive a flexible pillow 7. Among them, the flexible pillow 7 is a U-shaped flexible pillow 7.

[0030] The multifunctional storage bag in the present application is composed of three bag layers, among which an intermediate bag layer 3 is sandwiched between the first outer bag layer 1 and the second outer bag layer 2. The specific structure in the case where the side edges are not closed is as Figure 2 shown. Among them, a bag opening 11 is provided on one side of the three bag layers, and the side edges where the bag opening 11 is not provided are subjected to a sealing edge 5 treatment to form a sealing edge 5 structure, specifically as Figure 1As shown in the figure. Sealing edges 5 are provided on the side edges of the first outer bag layer 1 and the middle bag layer 3 for sealing, and both the first outer bag layer 1 and the middle bag layer 3 are made of airtight materials. For example, airtight bag layers can be prepared using materials such as PE (polyethylene), PVC (polyvinyl chloride), and TPU (thermoplastic polyurethane elastomer) as the first outer bag layer 1 and the middle bag layer 3. The first outer bag layer 1 and the middle bag layer 3 are hermetically sealed to form a sealed cavity. A switching valve 6 is provided on the first outer bag layer 1, and the inner gas transmission through-hole of the switching valve 6 is connected to the sealed cavity. Then, inflation operation can be carried out into the sealed cavity through the one-way valve. At this time, gas is input into the sealed cavity through the inner gas transmission through-hole; deflation operation can also be carried out by pressing the one-way valve. At this time, the gas in the sealed cavity is output outward through the inner gas transmission through-hole. A receiving cavity 71 is formed between the second outer bag layer 2 and the middle bag layer 3. The receiving cavity 71 does not require airtight design. Then, the receiving cavity 71 can be used as a storage space to place the flexible pillow 7. The flexible pillow 7 can be a U-shaped flexible pillow such as a head pillow or a neck pillow. The opening of the receiving cavity 71 is also the bag opening 11 of the multifunctional storage bag, and the bag opening 11 is sealed by a sealing member 4.

[0031] The user can take out the flexible pillow 7 from the receiving cavity 71 for use. At the same time, gas is input into the sealed cavity through the switching valve 6 to form an inflated airbag. At this time, the use structure of the multifunctional storage bag is as Figure 5 shown.

[0032] In a more specific embodiment, the first outer bag layer 1, the second outer bag layer 2, and the middle bag layer 3 are all flexible bag layers made of flexible materials. Further, the second outer bag layer 2 is a transparent flexible bag layer made of transparent flexible materials.

[0033] Specifically, all three bag layers can be made of flexible materials, so that all three bag layers are flexible bag layers with a certain degree of flexibility. After gas is input into the sealed cavity, the flexible bag layer can, through its own tension, press the gas in the inner air pressure airbag, so that the formed airbag maintains a tensioned state and the sealed cavity is maintained in an inflated state. When the user squeezes against the airbag, the airbag can provide sufficient buffering force to the user; this avoids the airbag formed in the sealed cavity from deflating due to the non-flexible bag layer being set.

[0034] Further, the second outer bag body can also be set as a transparent flexible bag layer, so that the user can directly view the items placed in the receiving cavity 71 and the positions of the items through the second outer bag layer, which is more convenient for the user to take the items (such as the flexible pillow 7) placed in the receiving cavity 71.

[0035] In a more specific embodiment, the sealing member 4 is a drawstring 41, and the drawstring 41 passes through an annular channel provided at the bag mouth 11; the drawstring 41 passes out through a through hole provided at the end of the annular channel. Specifically, check valves 42 are provided at both ends of the drawstring 41, and the size of the check valve 42 is larger than the size of the through hole at the end of the annular channel.

[0036] Specifically, as Figure 3 and Figure 4 shown, the sealing member 4 can be set as a drawstring 41, and the drawstring 41 passes through an annular channel provided at the bag mouth 11. Check valves 42 are provided at both ends of the drawstring 41 to prevent the drawstring 41 from retracting into the annular channel and affecting the use. The structure when the drawstring 41 is not tightened is as Figure 3 shown. The user can place the flexible pillow 7 in the accommodation cavity 71, pull both ends of the drawstring 41 and tie them to close the bag mouth 11. The structure at this time is as Figure 4 shown.

[0037] In a more specific embodiment, the middle bag layer 3 and the second outer bag layer 2 are curled at the edge of the bag mouth 11 to form a curled cavity; the curled cavity of the middle bag layer 3 communicates with the curled cavity of the second outer bag layer 2 to form an annular channel; through holes are respectively opened at the positions corresponding to the ends of the middle bag layer 3 and the second outer bag layer 2 and the annular channel.

[0038] The curled cavity can be formed by curling the edges of the middle bag layer 3 and the second outer bag layer 2, so as to obtain an annular channel. The edge of the middle bag layer 3 can be set to be flush with the edge of the first outer bag layer 1, and its setting structure is as Figure 6 shown.

[0039] Alternatively, the first outer bag layer 1 and the second outer bag layer 2 are curled at the edge of the bag mouth 11 to form a curled cavity; the curled cavity of the first outer bag layer 1 communicates with the curled cavity of the second outer bag layer 2 to form an annular channel; through holes are respectively opened at the positions corresponding to the ends of the first outer bag layer 1 and the first outer bag layer 1 and the annular channel. Among them, there is a gap between the middle bag layer 3 and the edge of the bag mouth 11.

Further, a gap can be provided between the middle bag layer 3 and the edge of the bag mouth 11, and the edge of the middle bag layer 3 is located below the edge of the first outer bag layer 1.

[0041] In a more specific embodiment, the sealing member 4 is a sealing strip 43. The sealing strip 43 includes a concave sealing strip 431 provided on the side surface of the second outer bag layer 2, and a convex sealing strip 432 provided on the side surface of the intermediate bag layer 3. The concave sealing strip 431 and the convex sealing strip 432 are arranged opposite to each other. The specific setting structure of the sealing strip 43 is as Figure 6 shown. By applying an external force, the convex sealing strip 432 is embedded into the concave sealing strip 431, so as to seal the bag opening 11.

[0042] In the multifunctional storage bag provided by the embodiment of the present invention, it includes a first outer bag layer 1 and a second outer bag layer 2 that overlap each other. An intermediate bag layer 3 is sandwiched between the first outer bag layer 1 and the second outer bag layer 2; a bag opening 11 is provided on one side of the three overlapping bag layers, and a sealing member 4 is provided at the bag opening 11; a sealing edge 5 is provided on the side of the three overlapping bag layers where the bag opening 11 is not provided for sealing; sealing edges 5 are provided on the side edges of both the first outer bag layer 1 and the intermediate bag layer 3 for sealing.
