Reagent bottle plug puller

Abstract

The invention relates to the field of experiment instruments, in particular to a reagent bottle plug puller which aims at reducing harm to people when a reagent bottle is opened. According to the main scheme of the reagent bottle plug puller, the reagent bottle plug puller comprises a first inserting plate, a first connecting part and a handle. A first inserting opening which opens to the outer side of the first inserting plate is formed in the first side edge of the first inserting plate, and the distance between the two sides of the first inserting opening is matched with a cylinder, with the diameter being the first dimension, of an inner cover body. One end of the first connecting part is connected to the opposite side of the first side edge of the first inserting plate, and the first connecting part and the first inserting plate are mutually bent. The connecting end of the handle is connected with the first connecting part, and the holding end, relative to the connecting end of the handle, of the handle is located in the direction away from the first inserting plate. When the first inserting opening of the first inserting plate is inserted between the brim of the inner cover body and a reagent bottle opening, the holding end of the handle is rotated with the reagent bottle opening as the fulcrum to prize up the inner cover body, and therefore the reagent bottle cover body can be conveniently opened, and harm to people when the reagent bottle is opened is reduced.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a reagent bottle corkscrew. Background technique [0002] Reagents used in the laboratory are often characterized by hazardous properties such as strong acidity, strong alkalinity or strong volatility. Such as figure 1 As shown, in order to ensure good sealing of the reagents, the mouth of the reagent bottle 100 containing the reagents is usually covered with two caps. Wherein, the inner cover 300 is in the shape of a round hat, and the top of the inner cover in the shape of a hat is inserted into the bottle mouth of the reagent bottle upside down, and the cylindrical outer wall of the inner cover 300 is closely attached to the inner wall of the bottle mouth to play a sealing role. The ring brim 301 of the inner cover body 300 is pressed on the top of the bottle mouth. The outer cover 200 is in the shape of a hollow cylinder, and internal threads are provided on the inner...

Problems solved by technology

[0005] The inner cover of the reagent bottle and the bottle mouth of the reagent bottle are well sealed. The experimenter pulls the inner cover from the bottle mouth of the reagent bottle by hand, and the inner cover moves outward from the reagent bottle. Negative pressure will be generated in the reagent bottle. When the inner cover is separated from the reagent bottle, the instantaneous air flow generated by the negative pressure may take the liquid in the reagent bottle out and splash it on the hands of the experimenter, causing serious harm to the experimenter. harm

In addition, the inner cover is usually stained with reagent liquid, which is easily opened by hand, and it is also easy to stick to the hands of the experimenter.

When the experimenter wears latex gloves, it is not convenient to pull out the plug because the latex gloves are too thick; It is easy to be corroded and soaked by strong acids such as sulfuric acid, which will hurt the experimenters. Sometimes the staff will even consume a pair of disposable latex gloves when pulling out the cork once.
