Description

Technical Field

[0001] This utility model relates to the field of compression bags, and particularly to an inflatable headrest compression bag. Background Technology

[0002] Vacuum compression bags are used for storing everyday items, offering advantages such as space saving and mold and insect protection. They are also commonly used for carrying and storing items when traveling. However, their single storage function is no longer sufficient to fully realize their advantages. For outdoor camping, carrying fewer items and maximizing functionality is the preferred approach. Therefore, storage bags that offer multiple functions will undoubtedly be welcomed by users. Summary of the Invention

[0003] In view of the problems existing in the prior art, this utility model provides an inflatable headrest compression bag, which can be used as a compressed storage bag and also inflated as a headrest, making it a multi-purpose item for outdoor use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The inflatable headrest compression bag includes a top layer, a middle layer, and a bottom layer. The top layer and the middle layer are sealed on all four sides, and a heat-sealing line is set in the middle to connect the two layers. The inflation chambers between the two layers are connected. An integrated inflation and deflation valve is set on the top layer and is connected to the inflation chamber. The middle layer and the bottom layer are sealed on three sides, with one side being an open end with a sealing strip. An air extraction valve is set on the bottom layer and is connected to the cavity between the two layers.

[0005] A further improvement is that the top and bottom layers are both made of a composite material of fabric and PE, and the middle layer is a symmetrical nylon co-extruded film. The bag is sturdy, and the head provides a comfortable contact with the bag body.

[0006] A further improvement is that the heat-sealing line consists of two lines, dividing the inflation chamber into three sections. The width of the middle inflation chamber is smaller than the widths of the two side inflation chambers, resulting in a pillow shape with a central depression after inflation. When inflated, the front and back surfaces are higher than the middle surface, supporting the neck and preventing it from being unsupported, thus improving sleep comfort.

[0007] A further improvement is that the integrated inflation and deflation valve is located on the side of one end of the central inflation chamber. This allows for faster inflation and dispersion of the valve within the central chamber, and the side-mounted valve prevents head bumps, making it more comfortable to use.

[0008] A further improvement is that the heat-sealing line is not connected to the two ends, leaving three interconnected air chambers at the two ends. This allows for faster airflow and creates a pillow that is high around the edges and concave in the center. Beneficial effects

[0009] This invention extends the use of a storage compression bag into an inflatable headrest, making it suitable for outdoor camping, achieving multi-purpose portability, and reducing the amount of items to carry. Attached Figure Description

[0010] Figure 1This is a front view of the present utility model; Figure 2 This is a reverse side view of the present invention; Figure 3 for Figure 1 A screenshot of AA. Detailed Implementation

[0011] like Figures 1 to 3 As shown, this utility model includes a bag body comprising a top layer 1 and a bottom layer 3 made of a composite material of cloth and PE, and an intermediate layer 2 made of symmetrical nylon co-extruded film. The top layer 1 and the intermediate layer 2 are sealed on all four sides, and a heat-sealing line 4 is formed by heat sealing in the middle horizontally to connect the two layers, forming an inflation cavity 5 between the two layers. There are two heat-sealing lines 4, which separate the inflation cavity 5 into three parts. The heat-sealing lines are not connected to the two ends, and the two ends have three communication channels for the inflation cavities. The width of the middle inflation cavity is smaller than the width of the two side inflation cavities. After inflation, the top surface forms a pillow shape with a central depression. An integrated inflation and deflation valve 6 is provided on the top layer 1 at one end of the middle inflation cavity, which is connected to the inflation cavity 5. The intermediate layer 2 and the bottom layer 3 are sealed on three sides, with one side being an open end with a sealing strip 7. An air extraction valve 8 is provided on the bottom layer 3, which is connected to the cavity 9 between the two layers.

[0012] When used as a storage bag, place items inside the cavity 9, seal the sealing strip 7, and remove air from the cavity through the air extraction valve 8, using it as a regular compression bag. When a pillow is needed at night, inflate the cavity through the inflation valve 6. After expansion, it forms a pillow shape with high sides and a concave center. Tightening the valve cap allows inflation but not deflating, preventing air leakage during use. When not in use, loosening the valve cap releases air.

[0013] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
