Abstract
The utility model discloses a bottle cap capable of effectively sealing a reagent. The bottle cap comprises a bottle cap body, wherein the bottle cap body is provided with a liquid suction hole which penetrates through the bottle cap body, and a sealing device is arranged below the liquid suction hole. The bottle cap is simple in structure; a layer of special transparent film is coated on the liquid suction hole, so that a needle tubing can be smoothly inserted into the bottle body by virtue of the film on the liquid suction hole, and the probability that the reagent is polluted is reduced; in addition, the reagent bottle is effectively sealed so as to prevent the reagent from being in contact with external air, and therefore, the stability of the reagent is ensured.
Description
Technical field
The utility model relates to a kind of bottle cap, but especially relates to a kind of bottle cap of effective sealing reagent, belongs to medicine, chemical field.
Background technology
Reagent bottle is medicine and chemical industry container commonly used.General, it comprises bottle and bottle cap, and bottle is to have flat container, and bottle cap is connected with the bottle opening part by the mode that is spirally connected.During use, open bottle cap and insert in bottle and extract reagent with needle tubing.After the bottle cap of available reagent bottle was opened, bottle was all uncovered,, though be beneficial to like this extraction of reagent, often pollute, and reagent was volatile, and uncork stability reduces.And when taking down bottle cap and extracting reagent,, at first because bottleneck is larger, easily cause the outside spilling of reagent or fall into foreign material contaminated; Secondly, when bottle cap is opened for a long time, in bottle, a reagent large tracts of land contacts with outside air, easily causes the chemical reaction such as reagent generation oxidation to reduce its stability, and easily causes reagent to volatilize.Therefore be necessary to be improved.
The utility model content
The purpose of this utility model is to overcome the available reagent bottle to be needed in use to open fully bottle cap and extracts the problems that reagent brings, but designed a kind of bottle cap of effective sealing reagent, this bottle cap, by having covered the special transparent membrane of one deck on the drawing liquid hole, has solved the problem that need to open bottle cap while extracting reagent fully.
The purpose of this utility model is achieved through the following technical solutions: but a kind of bottle cap of effective sealing reagent comprises body of the bottle lid, is provided with the drawing liquid hole of running through body of the bottle lid on described body of the bottle lid, and below, described drawing liquid hole is provided with sealing device.
In technique scheme, body of the bottle lid is existing structure, by the drawing liquid hole is set on body of the bottle lid, the preferred sealing film that arranges in below, drawing liquid hole, reduce the way that need to open bottle cap when tradition extracts reagent fully, extract reagent after utilizing needle tubing puncture through seal film, making the passage that reagent contacts with air is only a needle tubing mouth, reduce the probability that reagent contacts with air, make uncork stability improve.
Further, described sealing device is transparent membrane, and transparent membrane is cylindrical structure, and its end face contacts with the bottom in drawing liquid hole; The diameter of described transparent membrane is greater than the diameter in drawing liquid hole; The dead in line in the axis of described transparent membrane and drawing liquid hole.The sealing device preferred film, utilize transparent membrane to stretch and flatten, after needle tubing punctures, can automatically shrink, pin hole is covered, reduce the probability that reagent contacts with air, the sidewall of transparent membrane preferably can contact with the inwall of body of the bottle lid, makes installation stability higher.
Further, the below of described transparent membrane is provided with pad, and the top of pad contacts with the bottom of transparent membrane; Described pad is cylindrical structure, and the dead in line in the axis of pad and drawing liquid hole.Pad is as the device that supports transparent membrane, make transparent membrane to stablize and be pressed on the drawing liquid hole, in order to avoid the pressure that brings when needle tubing punctures transparent membrane causes the transparent membrane displacement even to come off, the sidewall of pad is pressed on the internal face of body of the bottle lid, makes to install and stablizes.
Further, described pad center is provided with through hole, and the diameter of through hole is greater than the diameter in drawing liquid hole.Just can extract reagent in order to make needle tubing can just pierce through transparent membrane, thereby at the pad center, through hole is set, the secondary that has reduced needle tubing penetrates, and has improved extraction efficiency.
Further, described drawing liquid is provided with tegillum in hole, and tegillum is arranged on the transparent membrane top; Described tegillum is cylindrical structure, and cylinder one end is arranged in the drawing liquid hole, and the other end is arranged on the body of the bottle lid outside.Tegillum is as from top seal, living the drawing liquid hole, prevents that dust etc. from entering into the drawing liquid hole, opens tegillum again while needing to extract reagent.
Further, be provided with boss on the sidewall of described tegillum, and boss is arranged on the outside of body of the bottle lid, the bottom of boss contacts with the top of body of the bottle lid.Boss is the block structure of stretching out little cover outer wall, facilitates the user to open tegillum, and is more laborsaving.
In sum, the beneficial effects of the utility model are: this Bottle cap structure is simple, and by covered the special transparent membrane of one deck on the drawing liquid hole, the film on this drawing liquid hole not only is beneficial to needle tubing and inserts smoothly bottle, has reduced the contaminated probability of reagent; And effective sealing reagent bottle, avoided reagent to contact with outside air, make the stability of reagent be guaranteed.
