If the thickness of the isolation film in the non-destructive area is set to 1mm, the thickness of the isolation film in the damaged area can be set to 0.1mm. And the whole isolation membrane is stretched and flattened during installation, so that after the lower end of the lower tube body descends and contacts the isolation membrane and passes through, the isolation membrane within the damage zone will be separated, as shown in Figure 14, after separation, a membrane is formed in the center of the isolation membrane. The perforation 11a is for the circulation of liquid material or mixture. As shown in Figures 11 and 12, the isolation film of the remaining peripheral portion will remain on the lower surface of the separator, which does not affect the flow of materials. After the actual test, when the isolation film is stretched and flattened and fixed, the lower end of the lower pipe body can drive the isolation film within the damage area to separate. Affect the circulation of liquid or mixture, that is, through the gap formed by the damaged part, without affecting the use effect.

The outer periphery of the separator and the lower surface of the separator can be connected by conventional methods such as bonding; the separator can be aluminum foil or other waterproof film type materials.

Both the first limit seal ring 3a and the second limit seal ring 3b can be torn apart, and play a role of encapsulation before tearing, and after tearing, the outer thread of the outer wall of the bottle mouth can be exposed to provide the bottle cap to continue rotating and descend channel until it is tightened, the tearable limit sealing ring is the prior art, and it is often used in liquid medicine bottle packaging, beverage packaging or glass bottle yogurt packaging, such as Huahuaniu glass bottle yogurt, etc. In the technical solution of the present application , the first limit seal ring and the second limit seal ring are separated from each other, that is, the tearing of one of the two will not affect the other. After the first limit seal ring is torn, the top cover can rotate and continue to descend. The lower end of the lower tube body 63 breaks the isolation membrane 11 until it is restricted by the second limit sealing ring, and the liquid material 13 in the upper storage cavity 12a can pass through the outer wall of the lower tube and contact the The gap between the inner walls of the mixing hole flows into the lower storage cavity 12b, and the second limit sealing ring is torn off to rotate the top cover and continue to descend, as shown in Figure 12, until the lower end of the lower pipe body 63 is pressed tightly against the mixing material. The mixing hole is sealed on the hole 10 , so that the liquid material and powder material fully mixed in the lower storage chamber can be led out through the lead-out channel 15 .

At the same time, the second limit sealing ring also acts as a limiter, and the descending distance of the top cover after tearing is limited at most, which can prevent too much screwing.

The casing 12 where the lower storage chamber 12b is located is made of elastic material, such as plastic, rubber, etc., and the mixed material can be sent out from the lead-out channel 15 by squeezing the lower storage chamber.

A method for separating, storing and mixing materials based on the above-mentioned dropping capsules. First, the liquid material 13 is stored in the upper storage cavity 12a, and the powder material is stored in the lower storage cavity 12b. The top cover 2, the first limit seal The ring 3a and the second limit sealing ring 3b are encapsulated, and the upper storage chamber 12a and the lower storage chamber 12b are isolated by the isolation film 11 below the mixing hole 10, so as to separate and store the liquid material and the powder material;

When mixed use is required, first tear off the first limit seal ring 3a, tighten the top cover on the upper surface of the second limit seal ring 3b, and extend the tube downward during the downward movement of the top cover, thereby pushing the inner suction tube downward, pushing The lower pipe body 63 goes down, the bellows is elongated, the lower end of the lower pipe body 63 breaks the isolation membrane 11, and the gap between the outer wall 632 of the lower end of the pipe body and the inner wall 101 of the mixing hole constitutes that the upper storage chamber and the lower storage chamber communicate with each other. The guide channel, the liquid material stored in the upper storage cavity flows into the lower storage cavity from the guide channel;

Tear off the second limit sealing ring 3b, continue to rotate the top cover, and the top cover continues to rotate downward, so that the outer wall of the lower end of the lower pipe body is pressed against the inner wall of the mixing hole to seal the mixing hole, and seal and isolate the upper storage cavity and the lower storage cavity;

firstly, liquid materials (13) are stored in an upper storage cavity (12a), powder materials are stored in a lower storage cavity (12b), the upper storage cavity (12a) and the lower storage cavity (12b) are packaged through a top cover (2), a first limiting sealing ring (3a) and a second limiting sealing ring (3b), and meanwhile the upper storage cavity (12a) and the lower storage cavity (12b) are isolated through an isolating film (11) below a mixing hole (10), so that the liquid materials and the powder materials are stored in a separated mode;

when the two-way mixing device is required to be used in a mixing mode, the first limiting sealing ring (3a) is torn firstly, the top cover is screwed on the upper surface of the second limiting sealing ring (3b), the delay tube descends in the descending process of the top cover, so that the inner suction tube is pushed to descend, the lower tube body (63) is pushed to descend, the corrugated tube is elongated, the lower end of the lower tube body (63) breaks the isolation film (11), a flow guide channel is formed by a gap between the outer wall (632) of the lower end of the lower tube body and the inner wall (101) of the mixing hole, the upper storage cavity and the lower storage cavity are communicated with each other, and liquid materials stored in the upper storage cavity;

tearing the second limiting sealing ring (3b), continuously rotating the top cover, and continuously rotating the top cover to move downwards so that the outer wall of the lower end of the lower pipe body is tightly pressed on the inner wall of the material mixing hole to seal the material mixing hole and hermetically isolate the upper storage cavity from the lower storage cavity;

the shaking shell is formed by uniformly mixing two materials to form a mixture, and when the shaking shell is required to be used, the mixture is led out from the leading-out channel (15).
