Abstract
The utility model discloses a chemical reagent bottle cap which comprises an outer cap, wherein the inner wall of the outer cap is provided with an inner thread, and the inner thread is matched with an outer thread at the mouth of the reagent bottle to seal the reagent bottle. The chemical reagent bottle cap is characterized in that the middle part of the inner side of the outer cap is fixedly provided with an inner cap of a long cylindrical shape, and the upper end of the inner cap is fixed on the inner wall of the top of the outer cap; and a cushion is arranged between the inner wall of the outer cap and the outer wall of the inner cap. The chemical reagent bottle cap has the advantages of simple structure and convenience in use and can be used for weighing liquid; and when the chemical reagent bottle cap is used for pouring residual liquid back, the residual liquid cannot be spilled, which is safe and sanitary, so that the experiment efficiency is improved.
Description
Technical field
The utility model relates to a kind of improvement of bottle cap, specifically a kind of chemical reagent bottle cap.
Background technology
At present, chemical reagent bottle is the article of often using in the middle school chemical experiment, and chemical reagent bottle cap on the market generally is comprised of an enclosing cover, and its shape is exactly the cylindrical shape of an end opening.Such bottlecap functionality only is used for the sealing to container bottle, and picking and placeing liquid needs to use in addition the independent instruments such as graduated cylinder.If pick and place liquid with this bottle cap on the market, will measure inaccurately, and when unnecessary liquid is refunded container bottle, spill easily and drain to the bottle outside.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and can pick and place easily the chemical reagent bottle cap of liquid in the reagent bottle.
In order to reach above purpose, technical scheme that the utility model adopts is: this chemical reagent bottle cap, comprise enclosing cover, at the negative thread that the madial wall of enclosing cover arranges, the negative thread use that matches with the outside thread of reagent bottleneck comes the sealed reagent bottle, it is characterized in that: the middle inside at enclosing cover is fixed with inner cap, inner cap is oval tubular, and its upper end is fixed on the top inner wall of enclosing cover, is provided with pad between the outer wall of the inwall of enclosing cover and inner cap.
The utility model is also implemented by following measure: described inner cap is that transparent material is made, and scale mark is set above the inner cap.
The beneficial effects of the utility model are: easy to use, and can directly measure liquid with bottle cap, and can when raffinate is refunded reagent bottle, not leak outside, safety and sanitation have improved conventional efficient, have saved reagent.
Description of drawings
Fig. 1 is structure cross-sectional schematic of the present utility model;
Among the figure: 1, inner cap; 2, enclosing cover; 3, screw thread; 4, pad.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.This chemical reagent bottle cap, comprise enclosing cover 2, the negative thread 3 that arranges at the madial wall of enclosing cover 2, negative thread 3 use that matches with the outside thread of reagent bottleneck comes the sealed reagent bottle, and it is characterized in that: the middle inside at enclosing cover 2 is fixed with inner cap 1, inner cap 1 is oval tubular, its upper end is fixed on the top inner wall of enclosing cover 2, is provided with pad 4 between the outer wall of the inwall of enclosing cover 2 and inner cap 1, and pad 4 plays the effect of further sealed reagent bottle.
Described inner cap 1 is that transparent material is made, and above the inner cap 1 scale mark is set.When measuring liquid with inner cap 1, can see reading clearly like this.
When using the utility model, operating personal can not need to use in addition the instruments such as graduated cylinder, just can pour liquid into and measure in the inner cap 1, by scale mark can make measure more accurate.Measure finish after, cover bottle cap because inner cap 1 diameter is less than the reagent bottle bottleneck, so residual liquid is exactly to flow in the reagent bottle fully, rather than flows to the bottle outside and come, easily, and stopped to produce dangerous because of liquid leakage.
