Abstract
It the utility model is related to a kind of food inspection volumetric flask, it is to be made up of bottle and lid, there is lid at the top of bottle, bottle is made up of body and bottleneck, connection bottleneck at the top of body, body inside bottom has a collecting tank, and the position of constant volume graduation mark is provided with bulge-structure on bottleneck, and the volume of the bottleneck of constant volume graduation mark to bottle accounts for the 10%~15% of whole bottle volume.The beneficial effects of the utility model are：A kind of food inspection volumetric flask of the present utility model, its internal solution is conveniently drawn, especially when only remaining less amount of solution, remaining solution can be all gathered in collecting tank, convenient to draw；Bulge-structure on its constant volume graduation mark, can make the concave surface of liquid level seem to become apparent from, and make constant volume more accurate；The volume of its constant volume graduation mark to bottle body and bottleneck is smaller simultaneously, and its center of gravity is lower more stable, places whole bottle more stable；Its lid is designed to make lid coordinate even closer with bottleneck, avoids the generation of leakage.
Description
Technical field
The utility model belongs to chemical detection instrument field, and in particular to a kind of food inspection volumetric flask.
Background technology
Volumetric flask is a kind of conventional glassware during food inspection, but existing volumetric flask is due to its center mistake
Height, it can often knock over；And the internal diameter due to neck part during constant volume is smaller, the concave surface of liquid level is difficult it is clear that this will
Cause constant volume inaccurate, and then influence testing result；Volumetric flask does not match somebody with somebody the instrument of liquid still, can act also as liquid storage and uses, and
When drawing constant volume solution, during especially last a small amount of solution, it is often difficult to draw, in turn results in waste；And volumetric flask
Lid is frosting, if using for a long time, it is easy to wear, thus the situation of leakage can be caused to occur.
Utility model content
In order to solve above mentioned problem existing for prior art, the utility model provides a kind of food inspection volumetric flask.
Technical scheme is used by the utility model：
A kind of food inspection volumetric flask, is made up of bottle and lid, and lid, bottle are buckled with the top of described bottle
It is made up of body and bottleneck, the top connection bottleneck and body of body are connected with bottleneck, and the bottom on the inside of body is provided with liquid collecting
Groove, bottleneck are provided with constant volume graduation mark, and the position of constant volume graduation mark is provided with bulge-structure, constant volume graduation mark to bottle on bottleneck
The volume of bottleneck accounts for the 10%~15% of whole bottle volume.
As further improvement of the utility model, described lid is provided with abduction for cylinder, its top surface of under shed
Circular outer edge, the bottom of outer rim is provided with bulge loop, and the bottom of lid inwall is provided with buckle, and it is convex that the bottleneck of bottle is provided with circular arc
Rise, buckle is engaged with arc-shaped convex.
As further improvement of the utility model, the horizontal center line of described bulge-structure is mutually overlapping with constant volume graduation mark
Close.
The beneficial effects of the utility model are：A kind of food inspection volumetric flask of the present utility model, conveniently draws in it
The solution in portion, especially when only remaining less amount of solution, remaining solution can be all gathered in collecting tank, convenient to draw；Its
Bulge-structure on constant volume graduation mark, the concave surface of liquid level can be made to seem to become apparent from, make constant volume more accurate；It is fixed simultaneously
It is smaller to hold the volume of graduation mark to bottle body and bottleneck, its center of gravity is lower more stable, places whole bottle more stable；Its lid
It is designed to make lid coordinate even closer with bottleneck, avoids the generation of leakage.

Embodiment
As shown in figure 1, a kind of food inspection volumetric flask of the present utility model, is made up of bottle 1 and lid 2, it is described
The top of bottle 1 be buckled with lid 1, described lid 2 is provided with the circular outer edge 8 of abduction for cylinder, its top surface of under shed,
The bottom of outer rim 8 is provided with bulge loop 9, and the bottom of the inwall of lid 2 is provided with buckle 10, and the bottleneck of bottle 1 is provided with arc-shaped convex 11, institute
The horizontal center line for the bulge-structure 7 stated coincides with constant volume graduation mark 6；Buckle 10 is engaged with arc-shaped convex 11, and it is covered
Body is designed to make lid 2 coordinate even closer with bottleneck, avoids the generation of leakage, while when needing opening cover 2,
Only it need to can open lid 2 by being broken on bulge loop 9；Bottle 1 is made up of body 3 and bottleneck 4, the top of body 3 connection bottleneck 4 and
Body 3 is connected with bottleneck 4, and the bottom of the inner side of body 3 is provided with collecting tank 5, its convenient solution drawn inside bottle 1, especially
It is that remaining solution can be all gathered in collecting tank 5 when only remaining less amount of solution, it is convenient to draw；Bottleneck 4 is provided with constant volume
Graduation mark 6, the position of constant volume graduation mark 6 is provided with bulge-structure 7 on bottleneck 4, the bulge-structure on its constant volume graduation mark, can make
The concave surface of liquid level seems to become apparent from, and makes constant volume more accurate；The volume of constant volume graduation mark 6 to the bottleneck of bottle 1 accounts for entirely
The 10%~15% of bottle volume, the volume of its constant volume graduation mark to bottle body and bottleneck is smaller, and its center of gravity is lower more stable, makes whole
Bottle is placed more stable.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within the scope of protection of the utility model.
