Because the lower port of the anti-fake tube extends into the inner cavity of the container and is communicated with the inner cavity of the container, when the anti-fake tube is taken down, the inner cavity of the container can contain residual substances and can not be taken out from the lower port of the anti-fake tube, at the moment, if the substances in the inner cavity of the container are required to be completely taken out, the anti-fake tube is required to be separated from the clamping interface of the base through foreign objects, so that the anti-fake tube and the anti-fake assembly fall into the inner cavity of the container, at the moment, the clamping interface of the base is used for communicating the inner cavity of the container with the upper opening of the base, the base is inclined, and the residual substances in the inner cavity of the container can completely flow out of the upper opening of the base through the clamping interface of the base; the anti-fake tube and the anti-fake assembly fall into the inner cavity of the container, so that the integrity of the cover assembly is damaged, and when a user shakes the container, the anti-fake tube collides with the inner wall of the container to make a sound, so that the anti-fake tube is convenient for the user to identify better, has a good anti-fake effect and is remarkable in anti-fake effect.

2. Prevent being equipped with on the false pipe outer wall with the first joint ring of base joint interface oral area edge joint complex, first joint ring is located base joint interface top can make to prevent that false pipe is connected more firm with the base, prevents that the lid subassembly from not assembling before the container oral area and transportation, deposit the in-process and prevent that false pipe breaks away from base joint interface and loses, drops.

3. Prevent on the false pipe outer wall and lie in first joint ring below and still be equipped with the second joint ring, first joint ring is located base joint mouth top just the second joint ring is located base joint mouth below, ensures to prevent that the false pipe can only slide in the slip range of settlement, can only slide at the interval between first joint ring and the second joint ring promptly, prevents to prevent that the distance undersize between false pipe upper port and the base upper shed causes the ball sealer activity space undersize, or leads to the ball sealer with the base upper shed with prevent that the port shutoff on the false pipe, causes out the liquid difficulty.

4. The base lower extreme just is formed with the pin to the container inner chamber along the circumference of base joint interface, the pin lower extreme supports to lean on preventing false subassembly, when the slope is rewound, can prevent false subassembly and prevent that the false pipe rebound, ensures promptly that the port stretches into the container inner chamber all the time under preventing false pipe, guarantees that container inner chamber part material can not flow through port under the base.

5. And a limiting structure which can be positioned at a set position when the anti-fake block rotates to open or close relative to the anti-fake seat is arranged between the anti-fake seat and the anti-fake block. When the anti-fake block can be prevented from being opened by rotating relative to the anti-fake seat through the limiting structure, the rotating amplitude is too large or too small, so that the opening effect of the anti-fake block is poor, namely, the anti-fake block is ensured to be opened to a set position by rotating relative to the anti-fake seat, and the anti-fake assembly can not be taken out from the opening part of the container.

6. The sealing ball is arranged between the upper opening and the lower opening of the base and above the base clamping port, the sealing ball can plug the upper port of the anti-fake tube and plug the base clamping port when the anti-fake tube falls into the inner cavity of the container, and when the anti-fake tube is stopped to be taken down for use, the sealing ball can automatically plug the upper port of the anti-fake tube or the base clamping port in time, so that the problem of complex operation caused by the fact that a user manually plugs the upper port of the anti-fake tube or the base clamping port is solved, and therefore the anti-fake tube sealing device has the advantages of being convenient to operate, safe and sanitary.

7. The anti-fake component is characterized in that a blocking structure is arranged between the ejector rod and the anti-fake pipe or the anti-fake seat, the blocking structure can prevent the ejector rod from moving upwards after the ejector rod moves downwards to rotate and open the anti-fake block, the ejector rod can be ensured to be always abutted and connected with the anti-fake block, the anti-fake block is ensured to be always opened relative to the anti-fake seat, the anti-fake component can not be taken out of the mouth of the container, and the anti-fake effect is ensured.

When the ejector rod 43 moves downwards to act on the anti-fake block 32 to rotate and open relative to the anti-fake seat 31, the blocking structure 6 is arranged to prevent the ejector rod 43 from being separated from the through hole 311, that is, the side wall of the ejector rod 43 is always abutted against the side wall of the anti-fake block 32 to prevent the anti-fake block 32 from rotating and folding, so that the anti-fake component 6 is prevented from being taken out of the container opening, and the anti-fake effect is ensured.

As shown in fig. 1-7 and 9, the blocking structure 6 includes an inverted buckle/barb 61 disposed on the outer wall of the ejector rod 43, and a blocking groove 62 disposed on the inner wall of the anti-fake tube 2 or the inner wall of the through hole 311 of the anti-fake seat 31 and cooperating with the inverted buckle/barb 61 to block the ejector rod 43 from moving upward is provided. When the pushing rod 43 moves downwards to act on the anti-fake block 32 to rotate and open, the reverse buckle/barb 61 is clamped into the blocking groove 62 along with the downward movement of the pushing rod 43, so that the pushing rod 43 is prevented from moving upwards, the side wall of the pushing rod 43 is ensured to be always abutted against the side wall of the anti-fake block 32 to prevent the anti-fake block 32 from rotating and folding relative to the anti-fake seat 31, the anti-fake tube 2 and the anti-fake assembly 3 are ensured not to be taken out from the opening of the container, and if the anti-fake tube and the anti-fake assembly 3 need to be taken out, the container needs to be damaged.

As shown in fig. 8 and 9, the ejector pin 43 comprises a first push rod 431 movably disposed in the anti-false pipe 2, a second push rod 433 is connected to the lower end of the first push rod 431 through a tearable connection point/rib 432, the plug 430 is formed by the second push rod 433, and the blocking structure 6 is a tearable connection point/rib 432. When the pushing rod 43 moves downwards and the anti-fake block 32 rotates and opens, the lower end of the second pushing rod 433 penetrates through the through hole 311 and is inserted into the positioning blind hole 3121, the contact area between the side wall of the second pushing rod 433 and the side wall of the through hole 311 and between the anti-fake block 32 and the side wall of the positioning blind hole 3121 is increased, so that the friction force between the second pushing rod 433 and the anti-fake component 3 is increased, and at this time, if the first pushing rod 431 is driven to move upwards by external force, the connecting point/rib 432 is torn off, so that the first pushing rod 431 is separated from the second pushing rod 433, and the side wall of the second pushing rod 433 is ensured to be always abutted against the anti-fake block 32 to prevent the anti-fake block 32 from rotating and folding.
