Fig. 6 is an appearance view of a conventional vacuum storage bag.

Please refer to Fig. 1, the present invention is mainly a bag body 10, one end of which is closed, and two opposite inner sides of the opening of the other end respectively form a pressing strip 11 that can be pressed together and the concave and convex are opposite to each other, and can be pressed in a simple way. Bar 11 is pressed together, and bag body 10 can be completely closed; In addition, a one-way valve body 20 is set on bag body 10, as shown in Figure 2, valve body 20 must possess the function of one-way air intake, namely its It can only allow air to leak out from the inside of the bag body 10 and not allow air to be filled into the bag body 10 from the outside of the bag body 10. As shown in Figure 2, it is a preferred embodiment, and its valve body 20 is a central valve body. For a pipe body with smaller caliber and larger diameters at both ports, a plug body 21 of a corresponding shape can be provided. The two ends of the plug body 21 are large and the center is small, so that the inside of the pipe body can be sealed when it moves outwards. On the contrary, the opening on the outside of the pipe body is sealed, and a plurality of channels 22 are arranged on the side of the larger diameter part of the lower part of the plug body 21, so that when the plug body 21 moves to the outside, the air can still pass through the channels 22 And communicate with the outside; In addition, an intermediary body 30 of an appropriate type is provided in the bag body 10 .

Please refer to Fig. 1 and Fig. 3, when the present invention is in use, an intermediary body 30 is placed in the bag body 10, which can be non-woven fabric or sponge cloth, etc., with air-permeable objects, and the preserved objects can be placed in the bag body In 10, the pressing strip 11 is pressed together to make the bag body 10 into a closed state, and the valve body 20 is connected to the air extraction device 13 with an air extraction pipe 12 for air extraction. Guide the plug body 21 to move to the outside of the bag body 10, so that the air in the bag body 10 is drawn out from the inside of the bag body 10 through the channel 22 of the plug body 21, and in the process of extraction, because the bag body 10 is equipped with There is an intermediary body 30, so the position of the bag body 10 in the valve body 20 will not cause the local vacuum due to sudden rapid extraction, and the two sides of the bag body 10 will be bonded to cause the air in the bag on the other side to not pass through. , and the air in the entire bag body 10 will be sucked out of the bag body 10 uniformly through the intermediary body 30, so that the air in the bag body 10 can be drawn out and the whole reaches the state of vacuum. 21, the external pressure is much greater than the pressure inside the bag body 10, so the plug body 21 will be squeezed toward the inside of the bag body 10 by the greater pressure from the outside, so that the other end of the plug body 21 seals the valve body 20 , and because this end does not have any design to allow air to pass through, the plug body 21 will always be squeezed by a large external pressure to achieve the purpose of maintaining the vacuum inside the bag body 10 until the user opens the pressing strip 11 The vacuum environment is removed.

The intermediary body 30 of the present invention can also be provided with concavo-convex lines directly on the inner side of the bag body 10, such as a flange 31, as shown in Figure 4, the flange 31 can be discontinuous or shorter than the width of the bag body. Setting, its principle is that the space in the bag body 10 can not be separated into two or more closed spaces, so that when the air is pumped, the phenomenon of not forming a partial vacuum can also be achieved.
