The bottle stopper 210 includes an integrally formed top component 211, a middle component 212, and a bottom component 213 from top to bottom. The top component 211 includes an upper part 2111 and a lower part 2112. The outer periphery of the middle component 212 is provided with a plurality of clamping blocks 2121. The bottom component 213 is embedded in the opening and has a plurality of sealing rings 2131 on its outer periphery. The bottle stopper frame 220 is mounted on the middle component 212 and is provided with a plurality of clamping slots 2121. The clamping blocks 2121 are mounted in a one-to-one correspondence with the clamping slots 221.

[0028] The bottle cap 300 covers the top of the bottle body 100 and the reinforced bottle stopper 200. A through hole 310 is provided on the top of the bottle cap 300 and the upper component 2111 is located in the through hole 310. A plurality of first limiting grooves 320 are provided on the upper interior of the bottle cap 300, and the lower component 2112 is installed in the first limiting groove 320 (the top of the bottle stopper skeleton is close to the bottom of the lower component and is also located in the first limiting groove, which improves the stability of the installation structure); a plurality of second thread structures 330 are provided on the lower interior of the bottle cap 300, and the cross-section of the second thread structure 330 is trapezoidal, and the second thread structure 330 is connected to the first thread structure thread 120.

[0029] Specifically, the first threaded structure 120 is provided with a plurality of first limit blocks 121, the second threaded structure 330 is provided with a first component 331 and a second component 332, and a second limit groove 333 is provided between the first component 331 and the second component 332, and (after the bottle cap is tightened on the bottle body) the first limit block 121 is located in the second limit groove 333 (to ensure self-locking).

[0030] More specifically, a (spherical) groove portion 2132 is provided at the bottom of the bottom component 213 .

[0031] Furthermore, an annular groove 130 is provided on the top of the bottle body 100, and the annular groove 130 is located below the first threaded structure 120. A plurality of second limit blocks 340 are also provided below the interior of the bottle cap 300, and the second limit blocks 340 are located below the second threaded structure 330 and (after the bottle cap is tightened on the bottle body) the second limit blocks 340 are buckled below the annular groove 130 (to improve self-locking performance).

[0032] Furthermore, the bottle body 100 is provided with a hand-held structure 140 (for easy taking).

[0033] For this utility model:

[0034] Some optimizations have been made to the original sampling bottle, including material optimization, fastening thread optimization and the addition of a stopper skeleton.

[0035] The cap and body of this sampling bottle are made of PVDF (polyvinylidene fluoride). In addition to the excellent properties of PTFE (polytetrafluoroethylene), PVDF's rigidity, hardness, and creep resistance are particularly outstanding. Its processing and molding properties are also significantly superior to PTFE, making it the toughest fluoroplastic. Currently, similar products mostly use PTFE (polytetrafluoroethylene) and PE (polyethylene). Considering the sampling bottle's operating environment requirements for radiation resistance, corrosion resistance, wear resistance, and sealing, as well as the considerations of mass injection molding production processes, PVDF (polyvinylidene fluoride) is the preferred material for the bottle body and cap.

[0036] The bottle cap and bottle body are locked together using a trapezoidal thread. Compared to rectangular threads, the inner and outer threads of the trapezoidal thread are tightly attached with tapered surfaces, which are less likely to loosen and provide a better tightening effect. The top thread end of the bottle body has a positive deviation, which cooperates with the negative deviation of the overall height of the bottle cap to ensure that the bottle cap is not over-positioned when tightened.

[0037] The original sampling bottle used a single stopper to seal the bottle, with the seal being an end-face seal. The stopper is now longer and deeper into the bottle opening, with three additional annular protrusions (i.e., sealing rings) added to provide a radial seal with the bottle opening. The stopper skeleton structure also enhances the strength of the silicone stopper (increasing support), and the stopper is integrally molded.

[0038] In addition, the center opening (i.e., the through hole) of the sampling bottle cap forms an interference squeeze with the silicone (top component), which not only increases the sealing but also effectively increases the resilience of the silicone after needle insertion.

[0039] It is worth mentioning that the technical features such as radioactive waste liquid involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional options in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0040] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
