Abstract
The utility model discloses a flask, belonging to the technical field of chemical equipment glassware. The flask disclosed by the utility model has the advantages of good sealing performance and simple structure. The technical key point of the utility model is as follows: the flask comprises a flask body, the flask body is provided with at least one frosted opening, and a container for containing liquid is arranged at the periphery of the upper end of the frosted interface.
Description
Technical field
The utility model discloses a kind of flask, specifically, is a kind of flask of favorable sealing property, belongs to chemical device glass apparatus technical field.
Background technology
Flask is a kind of conventional glass apparatus, because can resistance to certain heat being known as flask.In chemical experiment, be commonly used to holding liquid material as reaction vessel, distil container etc., have easy to use, the advantage of applied range.But, existing flask mouth is frosted interface normally, sealing property is general, although do not affect too much for general liquid liquid, liquid-solid chemical reaction, but all there is certain problem for the reaction that has gas to participate in, distillation etc., especially for trace detection, the gas leakage of a little may all produce fatal impact to result of the test, and this problem is perplexing experimenter always.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of favorable sealing property, flask simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is such: a kind of flask, comprise bottle, and bottle is provided with at least one frosted interface, is arranged with the container of contain fluid outside the upper end of described frosted interface.
Above-mentioned flask, described bottle is provided with three frosted interfaces, and the periphery, upper end of each frosted interface is equipped with the container of contain fluid.
Further, above-mentioned flask, described frosted interface and container are one-body molded.
Further, above-mentioned flask, described container is cylindric or coniform, the top of circular cone and frosted interface are one-body molded.
Further, above-mentioned flask, described bottle is flat bottle or round bottom bottle.
Compared with prior art, the flask that the utility model provides, in the upper end of frosted interface, be provided with the container of contain fluid, make it form the assembly by hydraulic packing in frosted interface and container, both improved the air-tightness of flask, facilitate again bubble-tight inspection and observation, guaranteed the reliability of result of the test.When concrete use, according to requirement of experiment, install experimental provision, at container, pack liquid into, be generally detecting glitch-free liquid, as oil or water, the hydraulic pressure in container forms fluid-tight air-tightness, fit common generation of seal group that the air-tightness of whole device is formed by frosted interface and container hydraulic pressure, if leak gas, in container, have Bubble formation, more directly perceived, facilitated airtight test and observation.
Accompanying drawing explanation
Fig. 1 is that the utility model is implemented 1 structural representation;
Fig. 2 is that the utility model is implemented 2 partial sectional view;
Wherein: bottle 1, frosted interface 2, container 3.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment; claim of the present utility model is described in further detail; but any restriction of the present utility model not in pairs; the modification of the limited number of time that anyone makes within the scope of the utility model claim, still in claim protection domain of the present utility model.
A kind of flask of the present utility model, the bottle 1 that comprises flat or round bottom, bottle 1 is provided with three frosted interfaces 2, in order to increase sealing, outside the upper end of each frosted interface 2, be arranged with the container 3 of contain fluid, in particular, described container 3 can be for cylindric, cylindrical container one end is around the upper end of frosted interface 2, one-body molded with it; Described container 3 also can be for coniform, and the top of coniform container is around the upper end of frosted interface 2, one-body molded with it.
A kind of flask of the present utility model, the bottle 1 that comprises flat or round bottom, bottle 1 is provided with a frosted interface 2, in order to increase sealing, outside the upper end of frosted interface 2, be arranged with the container 3 of contain fluid, in particular, described container 3 can be for cylindric, cylindrical container one end is around the upper end of frosted interface 2, one-body molded with it; Described container 3 also can be for coniform, and the top of coniform container is around the upper end of frosted interface 2, one-body molded with it.
When concrete use, according to requirement of experiment, install experimental provision, at container 3, pack liquid into, conventionally can select detecting glitch-free liquid, water on experimental result without impact condition under, the liquid that container 3 packs into is generally water, and like this, the hydraulic pressure in container 3 forms water seal air-tightness, fit common generation of seal group that the air-tightness of whole device is become with vessel water swaging by frosted interface, if leak gas, in container, have Bubble formation, more directly perceived, facilitated airtight test and observation.
In sum, the flask that the utility model provides has improved the air-tightness of flask, has facilitated again bubble-tight inspection and observation, guarantees the reliability of result of the test.
