A plurality of liquid channels 24 are arranged in an annular array around the axis of the perforating plug 25, so that the solution flows into the cavity 21 through the liquid channels 24 and flows out through the liquid outlet pipe 23.

The end surface of the cavity 21 connected with one end of the through hole plug 25 is attached to the annular edge of the plug opening 32 and is sealed; the through hole plug 25 is in a truncated cone shape. Specifically, the plug opening 32 is adapted to the piercing plug 25, and the end of the piercing plug 25 is inclined so that the end of the piercing plug 25 facing the inside of the bottle is contracted, in order to facilitate insertion of the piercing plug 25 into the plug opening 32.

Further, when the difference between R1 and R2 is greater than or equal to 2cm, the rubber seal 22 cannot be inserted into the hole, and both cannot be fitted. Therefore, preferably, the front-back phase difference between R1 and R2 is not more than 0.5 cm to 1cm, so that the rubber sealing piece 22 can be matched with the hole, and the fit is better; further, since the rubber sealing member 22 is made of rubber, when the rubber sealing member 22 is plugged into the hole with smaller inner diameter, the extruded rubber sealing member 22 is deformed, so that the joint between the extruded rubber sealing member and the hole is tighter, the sealing performance between the hole and the rubber sealing member 22 is improved, and the possibility of leakage of the solution is avoided.

The supporting members formed by the annular base 20, the cavity 21 and the perforated plug 25 are made of metal or/and hard plastic, specifically, the supporting members are preferably made of stainless steel or/and hard plastic (pvc), so as to avoid the problem that rust can occur in the later stage after the supporting members made of other materials are contacted with the solution in the bottle body 1, and the rust supporting members can influence the normal use of the solution in the use process; in other words, the supporting member provided in the present case is to support the bottle 1 better, and the selected supporting member is required to be made of non-deformable material, however, if other supporting members are selected, the present case can be applied, but if the other supporting members are required to influence the solution in the bottle 1, the appropriate supporting member materials are selected, so the present invention includes but is not limited to stainless steel materials and rigid plastics, and the appropriate materials can be selected according to the practical application environment and the application requirements.

It should be noted that, the outer diameter of the annular base 20 may be designed according to the actual application scenario, in this case, the outer diameter of the annular base 20 is narrower, but the annular base is used in cooperation with a chromatograph device, and a corresponding groove (in the prior art, which is not described herein in detail) is provided in the chromatograph device and cooperates with the annular base 20, so that the bottle body 1 is inverted and fixed on the chromatograph device; further, when the annular base 20 does not need to be used in cooperation with the chromatograph apparatus, the outer diameter of the annular base 20 needs to be larger than the outer diameter of the bottle body 1, so that the annular base 20 can support the bottle body 1 more stably.

When the bottle is used, the bottle opening plug 30 is plugged into the bottle opening, the bottle opening is plugged, the supporting piece formed by the perforation plug 25, the cavity 21 and the annular base 20 is plugged into the bottle opening plug 30, the perforation plug 25 with inclination can be well inserted into the bottle opening plug 30, then the annular base 20 is matched and fixed with chromatograph equipment, at the moment, the bottle body 1 is inverted, liquid enters the cavity 21 along the cambered surface 31 and the liquid channel 24, then the liquid is output along the liquid outlet pipe 23, and compared with the solution bottle which is put in the normal state, the inverted solution bottle is easier to run out the solution, the cost is saved, and the waste of the solution is avoided.

The auxiliary mechanism 3 is matched with the supporting mechanism 2 and connects the supporting mechanism 2 with the bottle body 1, so that the bottle body 1 is inverted and the solution in the bottle body 1 is extracted; the auxiliary mechanism 3 comprises a bottle mouth plug 30 which is connected with the bottle mouth of the bottle body 1, a plug mouth 32 which is communicated with the perforation plug 25 is arranged in the middle of the bottle mouth plug 30, the plug mouth 32 is in interference fit with the perforation plug 25, one end of the bottle mouth plug 30 is inwards concave with a cambered surface 31 towards the edge of the plug mouth 32, and the bottle mouth plug 30 is in interference fit with the bottle body 1; one end of the bottle mouth plug 30 is provided with a ventilation opening 6 for being inserted with the ventilation pipe 4, one end of the ventilation pipe 4 extending into the bottle body 1 is higher than the liquid level of the solution, the ventilation opening 6 is arranged on the end face of the bottle mouth plug 30, and filter cotton 5 is further accommodated in the ventilation opening 6.

In one embodiment, the curved surface 31 is concave in shape, so as to make the solution in the bottle body 1 flow to the center as much as possible, thereby determining the flow direction of the solution and facilitating the circulation of the solution.

Further, when in actual use, the bottle body 1 should not be fully filled with the solution, and a certain space needs to be reserved to ensure that the vent pipe 4 is high in liquid level after the bottle body 1 is inverted, so that air can be better introduced into the bottle through the vent pipe 4 when the bottle body 1 is inverted, the internal and external air pressure is balanced, and the liquid can be smoothly discharged out of the bottle.
