In this embodiment, the thickness of the puncturing portion 110 is 0.3mm to 0.5mm. Specifically, the piercing part 110 is molded together during the injection molding of the circular body 100, so that the injection molding difficulty of the piercing part 110 is low and the injection needle is convenient to pierce when the thickness of the piercing part 110 is between 0.3mm and 0.5mm, and the piercing part 110 is easy to break during the injection molding when the thickness is less than 0.3mm, and the injection molding difficulty is high; when the thickness of the penetration portion 110 is greater than 0.5mm, the penetration difficulty is great. Preferably, the thickness of the penetration portion 110 is 0.4mm.

Example 2
As shown in fig. 3, this embodiment differs from embodiment 1 in that: the second annular wall 500 is provided with a volatilizing groove 510 for communicating the first sealing cavity and the communicating cavity, and the inner wall of the first annular wall 400 is convexly provided with a limiting protrusion 420 for being in extrusion fit with the bottle mouth of the penicillin bottle to limit the bottle mouth of the penicillin bottle to continuously move upwards in a preset acting force, and the vertical height of the volatilizing groove 510 is lower than that of the sealing ring 200. Specifically, when the penicillin bottle is used for containing the freeze-dried medicine, the freeze-dried medicine needs to volatilize in the freezing process, when the first sealing cavity is pressed into the bottle mouth of the penicillin bottle, the bottle mouth of the penicillin bottle is limited to move upwards continuously through the extrusion fit of the limiting protrusion 420 and the bottle mouth of the penicillin bottle in a preset acting force, the penicillin bottle is in a half-covering state, the inside moisture can volatilize through the volatilizing groove 510, after the moisture volatilizes completely, the circular main body 100 is pressed by the acting force larger than the preset acting force, so that the bottle mouth of the penicillin bottle and the sealing ring 200 are mutually pressed, and the complete sealing of the penicillin bottle is realized. Alternatively, the volatilization grooves 510 are arranged in a plurality at intervals along the circumferential direction of the second annular wall 500.
Example 3
As shown in fig. 4, this embodiment differs from embodiment 1 in that: the inner diameter of the third annular wall 600 is greater than the outer diameter of the second annular wall 500. Specifically, when the penicillin bottle containing the vaccine is used, only the vaccine is required to be sucked after the injection needle is inserted, but as the vaccine dose is relatively less, the vaccine residue when the injection needle sucks the vaccine needs to be avoided as much as possible, and in the sucking process, the penicillin bottle is usually placed upside down so that the vaccine flows into the communication cavity to be sucked by the injection needle by utilizing gravity, at the moment, the vaccine in the communication cavity, which is lower than the needle head of the injection needle, cannot be sucked, and therefore, the inner diameter of the communication cavity is smaller than the inner diameter of the second injection cavity by the fact that the inner diameter of the third annular wall 600 is larger than the outer diameter of the second annular wall 500, so that the inner space of the communication cavity is relatively smaller, the vaccine amount which cannot be sucked is indirectly reduced, and the vaccine residue is avoided as much as possible.
The penicillin bottle of the embodiment comprises the penicillin bottle cap integrally sealed in the whole outer covering film in any embodiment. Specifically, through adopting the integrative sealed type xiLin bottle lid of whole tectorial membrane in sealed xiLin bottle's bottleneck to realize the reliable seal to plug 300 when not producing the aluminium powder bits, plug 300 need not extra fixed knot structure simultaneously and fixes, punctures or pulls out at the injection needle and can not be taken out, has simplified the inner structure of xiLin bottle lid greatly, and xiLin bottle's manufacturing processing degree of difficulty is low, and the degree of difficulty of use is low, and the practicality is strong, is suitable for extensive popularization and application.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
