[0044] Second waterproof layer 13: fixedly connected to the side wall of the inner non-woven fabric 12 away from the outer non-woven fabric 11, it is the key line of defense for the waterproof of the bag body 1. It can effectively prevent external water from penetrating into the bag, even in rainy days or humid environment, it can ensure that the goods in the bag are not damp, and provide reliable waterproof protection for the goods.

[0045] Usage instructions

[0046] In use, first, both hands hold the pull ring 2 on both sides of the top of the bag body 1, the protective sleeve 3 fixedly sleeved at the top end of the pull ring 2 can provide a comfortable holding feeling, avoiding the discomfort caused by the direct contact of the hands with the pull ring. Then, the zipper 5 on both sides of the protective layer 4 is pulled open, the design of the zipper 5 makes the protective layer 4 open and close conveniently, and the bag opening can be quickly opened. Then, the items to be kept warm or stored are placed stably in the bag body 1, and it is ensured that the items are located within the space range of the heat preservation and insulation mechanism 6, so that the heat preservation and insulation function is fully utilized; the heat insulation cotton 61 in the heat preservation and insulation mechanism 6 utilizes the low thermal conductivity to keep the items in the bag warm; the first waterproof layer 62 prevents water from entering the heat insulation cotton 61 and the aluminum foil 63, and the aluminum foil 63 not only prevents moisture but also assists in heat preservation and retains the freshness of hot food; when water is generated due to the condensation of water vapor in the bag, drainage operation is needed. Hold the threaded sleeve 10 with the hand, and rotate it in the counterclockwise direction, since the inner wall of the threaded sleeve 10 and the outer wall of the communication pipe 9 are threadedly connected, so during the rotation process, the threaded sleeve 10 gradually separates from the communication pipe 9. At this time, the water in the heat preservation and insulation mechanism 6 will flow into the communication pipe 9 through the inner cavity 8 under the action of gravity, and finally be discharged from the communication pipe 9, thereby reducing the humidity in the bag.
