Description
Technical Field
The invention relates to the technical field of dangerous goods reagent storage and sealing, in particular to a double-layer sealing cover for a reagent packaging bottle.
Background
Reagents, hazardous chemicals, biologicals, pharmaceuticals, etc. are typically contained in sealed-cap bottles, and the samples are typically highly volatile liquids or semi-liquids that generally do not allow direct contact or exposure to air. If the experimenter directly or indirectly contacts the toxic samples, physical damage can be caused; the test sample can pollute the experimental environment after leaking to the air; the shelf life of the sample can be influenced if the sample is contacted with air, the molecular structure of the product can be influenced, and some high-risk reagents can even explode if the sample is contacted with air. Therefore, the sample needs to be strictly sealed and stored in each link of transportation, sampling, use, storage and the like.
The bottle mouth and the bottle cap of the existing packaging bottle are usually in threaded connection, and a protruding step is arranged on the bottle mouth of the packaging bottle to prevent the bottle cap from falling off automatically. The sealing between the bottle mouth and the bottle cap is the most important link in the sample. The packaging bottle structure is difficult to seal. The existing bottle cap adopts the structural form shown in figure 1, and is mainly characterized in that a sealing gasket is arranged on one side, which is in contact with a bottle opening, and the structure shows that although the sealing bottle cap is of a double-layer cap structure, the upper cap of the sealing bottle cap needs to be turned over before a syringe is used for puncturing the sealing gasket for sampling, so that the sealing bottle cap is still a single-layer cap in essence during the sampling process.
Because the existing sealing bottle cap immediately generates a permanent and irreversible pore on the sealing gasket after the puncture type sampling of the injector is carried out, even if the upper cap is immediately buckled after the needle head is pulled out after the sampling is finished, part of the sample in the bottle leaks or volatilizes from the bottle cap through the pore. And the larger the puncture needle head is, the more the puncture times are, the larger the pore is, and the larger the corresponding sample leakage amount or volatilization amount is.
Meanwhile, after the puncture type sampling is finished, the upper cover is buckled on the lower cover, although the effect of sealing the sample in the storage process can be achieved, the sample in the packaging bottle still can leak or volatilize into the gap between the upper cover and the lower cover through the previous puncture hole due to the gap between the upper cover and the lower cover. When the sample is taken again, the upper cover is opened, and at the moment, part of the sample in the gap is leaked or volatilized into the air, so that secondary pollution is generated. The leakage or volatilization amount increases with the increase of the sampling times, and the risks caused by the leakage or volatilization of the sample are gradually accumulated. In order to guarantee safe use, generally only can carry out limited number and pierce formula sample, generally be 1 ~ 4 times, this has also restricted the container and the availability factor of packing bottle to a certain extent.
Patent document (CN201910520891.6) provides a self-sealing combined bottle cap, which solves the problem that the traditional bottle mouth cannot be sealed continuously after the medical liquid medicine is used, but the structure is not suitable for the occasion that the bottle cap needs to be inserted for taking liquid for many times. Therefore, in order to overcome the disadvantages and shortcomings of the conventional packaging cap product, a double-layer sealing cap which can be used with the conventional packaging bottle needs to be invented.
