DETAILED DESCRIPTION

[0014] like Figures 1 to 6As shown, the present invention comprises four layers: an upper film 1 for a bag body, an upper air column film 4, a lower air column film 5 and a lower film 2 for a bag body. The upper film 1 for a bag body and the lower film 2 for a bag body are connected by heat bonding on three sides, and a clamp chain 3 is provided on one side to form an opening and closing mouth. The upper film 1 for a bag body is connected on all sides to the upper air column film 4 below it, and an upper air column cavity 11 is formed therebetween. The lower film 2 for a bag body is connected on all sides to the lower air column film 5 above it, and a lower air column cavity 13 is formed therebetween. A storage cavity 12 is formed between the upper air column film 4 and the lower air column film 5. The upper film 1 of the bag body is connected to the upper air column film 4 at intervals, so that the upper air column cavity 11 is divided into multiple sub-cavities, and a connecting valve 6 is installed on a hole in the upper air column film 4 of each sub-cavity. A one-way valve II 10 is provided at the front end of each sub-cavity in the upper air column cavity 11, and a main air channel 14 connecting the sub-cavities is provided on the outer side of the one-way valve II of the sub-cavity. The one-way valve I8 is installed on the upper film 1 of the bag body corresponding to the main air channel, and the lower film 2 of the bag body is connected to the lower air column film 5 at intervals, so that the lower air column cavity 13 is divided into multiple sub-cavities, and a connecting valve 6 is installed on a hole in the lower air column film 5 of each sub-cavity. The connecting valve 6 of each sub-cavity on the upper air column membrane 4 corresponds vertically to the connecting valve 6 of each sub-cavity on the lower air column membrane 5, and a plug connector 7 that can be removed and plugged in is connected between the connecting valves 6. When the one-way valve I8 is inflated, each sub-cavity 11 of the upper air column cavity is filled with air through the one-way valve II 10, and each sub-cavity 13 of the lower air column cavity is filled with air through the connecting valve 6 to form an inflatable pillow. When the plug connector 7 is separated, the gas in the upper air column cavity and the lower air column cavity can be quickly emptied.

[0015] The male and female plug connectors 7 connected to the connecting valves 6 on the sub-cavities of the upper gas column cavity 11 are arranged at intervals, and the plug connectors 7 connected to the connecting valves 6 on the sub-cavities of the lower gas column cavity 13 are arranged correspondingly. When the lower gas column cavity leaks, the plug connectors on the adjacent sub-cavities of the upper gas column cavity can also be plugged in, and only the upper gas column cavity is used.

[0016] The bag upper film 1 or the bag lower film 2 is provided with an air extraction valve 9, which is connected to the storage cavity 12. There is also a separate inner liner bag 15 that can be placed in the storage cavity 12. The inner liner bag 15 is a bottom cloth 151 wrapped on the bottom plate, and a plurality of pockets 152 of different volumes are arranged on the front and back of the bottom cloth 151. The items are placed in the pockets and fixed, and the inner liner bag is placed in the storage cavity, and the air is extracted and compressed by the air extraction valve. Then, the present application is only used as a compression bag.

[0017] The middle position of the upper film 1 of the bag body is thermally bonded to form a plurality of folds 16, and the upper air column cavity 11 is inflated to present a concave shape with higher left and right sides and lower middle, which is more in line with human body mechanics and more comfortable to use.

[0018] The processing method of the multifunctional vacuum storage bag of this application: a. Prepare high-strength and durable materials as the main material of the bag (nylon or polyester material), and prepare thickened non-woven fabrics and PE sheets as the materials for the lining bag.

[0019] b. Use a cutting machine to accurately cut the nylon or polyester material according to the size and shape of the design drawing, including the upper film of the bag, the upper air column film, the lower air column film, and the lower film of the bag.

[0020] c. Perform local heat bonding on the inner side of the upper film of the bag body to form wrinkles, make holes on the upper film of the bag body to install one-way valve I and exhaust valve, make holes on the upper air column film to install connecting valve and plug joint, heat bond the upper film of the bag body and the upper air column film to form separate air cavities, install one-way valve II at the front end of each separate air cavity, and then heat bond the upper film of the bag body and the upper air column film around; make holes on the lower air column film to install connecting valve and plug joint, heat bond the lower film of the bag body and the lower air column film around to form separate air cavities, and then heat bond the lower film of the bag body and the lower air column film around; align the three sides (both sides and bottom) of the bag body and perform heat sealing treatment to ensure that the seal is firm and leak-free. A clip chain seal is set at the opening of the bag body.

[0021] d. Liner bag production: fix pocket fabrics of different sizes to the base fabric, and then wrap the base fabric on the PE base plate to ensure that the pockets are firm and beautiful.

[0022] e. Place the liner bag into the storage cavity of the storage bag and seal it with a clip chain. Then connect the air pump to the air extraction valve for an air extraction test to ensure the air tightness and load-bearing performance of the bag.

[0023] f. Take out the liner bag, connect the connecting valves on the upper air column cavity and the lower air column cavity with a plug connector, and then connect the air pump to the one-way valve I for inflation test to ensure the air tightness and load-bearing performance of the bag.

[0024] g. Conduct quasi-static load compression tests and multiple functional tests to ensure the reliability and stability of the product, and package qualified multi-functional vacuum storage bags.
