Abstract
A flask comprises a round-bellied flask body and a spindly flask neck, the flask body and flask neck are made of a transparent material, a light-shielding layer is covered on the surface of the flask, the light-shielding layer covers the flask body; and the light-shielding layer is provided with an observation window and a light-shielding curtain which can be opened and matched with the observation window. An experiment in the flask can be conveniently observed, and an experiment can be carried out in the flask in the absence of lights.
Description
Technical field
The utility model relates to a kind of container, particularly a kind of laboratory flask.
Background technology
Flask is conventionally in laboratory to have a neck glassware, is used for carrying liquid material, and can resistance to certain temperature.Flask has the round tripe body of carrying liquid and prevents that solution from spilling or reducing the thin neck of solution evaporation.Conventional flask comprises water white transparency flask and brown lucifuge flask.Water white transparency flask can be observed the experimental phenomena in flask.Brown lucifuge flask is for needing the chemical reaction of lucifuge processing.Hence one can see that, although water white flask is convenient to experimental observation, cannot carry out lucifuge test.Although brown lucifuge flask can carry out lucifuge test, experimental observation inconvenience.
Utility model content
Cannot carry out lucifuge test in order to overcome existing transparent flask, brown flask test is observed inconvenient shortcoming, and the utility model provides one viewing test easily, can carry out again the flask of lucifuge test.
A kind of flask, comprises round tripe body and elongated bottleneck that transparent material is made, it is characterized in that: flask surface coverage has light shield layer, and light shield layer covers body; Light shield layer is provided with watch window and the window-blind of raising with watch window adaptation.Light shield layer adopts exotic material to make.
Further, light shield layer covers bottleneck.
Further, light shield layer outer surface is black, and light shield layer inner surface is white.
Further, between described window-blind and light shield layer, be connected with magic tape.
In use, due to the parcel of light shield layer, the reactant in flask reacts the utility model under lucifuge condition.Need to observe the process of the test in flask time, window-blind is started.The inner surface of window-blind is white, and the background colour that makes flask is white, the change color while being convenient to viewing test.
The utlity model has viewing test easily, can carry out again the advantage of lucifuge test.
Accompanying drawing explanation
Schematic diagram when Fig. 1 is the test of the utility model lucifuge.
Fig. 2 is the schematic diagram of window-blind while starting.
Fig. 3 is cutaway view of the present utility model.
The specific embodiment
A kind of flask as Figure 1-3, comprises round tripe body 1 and elongated bottleneck 2 that transparent material is made, and flask surface coverage has light shield layer 3, and light shield layer 3 covers body 1; Light shield layer 3 is provided with watch window 5 and the window-blind of raising 4 with watch window 5 adaptations.Light shield layer 3 adopts exotic material to make.
Between described window-blind 4 and light shield layer 3, be connected with magic tape 6.Window-blind 4 has with the fixed edge of light shield layer 3 one and is covered on the active edges on light shield layer 3 by magic tape 6.Certainly, between window-blind 4 and light shield layer 3, also can be connected by magnetic clasp adhesive or by other manner, be not limited to of the present utility model giving an example.
In use, due to the parcel of light shield layer, the reactant in flask reacts the utility model under lucifuge condition.Need to observe the process of the test in flask time, window-blind is started.The inner surface of window-blind is white, and the background colour that makes flask is white, the change color while being convenient to viewing test.
The utlity model has viewing test easily, can carry out again the advantage of lucifuge test.
Content described in this description embodiment is only enumerating of way of realization to utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
Claims (4)
1. a flask, comprises round tripe body and elongated bottleneck that transparent material is made, it is characterized in that: flask surface coverage has light shield layer, and light shield layer covers body; Light shield layer is provided with watch window and the window-blind of raising with watch window adaptation, and light shield layer adopts exotic material to make.
2. flask as claimed in claim 1, is characterized in that: light shield layer covers bottleneck.
