Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pedestal for a round-bottomed container, and particularly to a pedestal for a round-bottomed container suitable as a pedestal for a round-bottomed experimental container such as a round-bottomed flask.

[Conventional technology]

In general, round-bottom containers such as round-bottom flasks are unstable when placed, so a pedestal is used to stably hold the container.

Conventionally, such pedestals having a funnel-shaped inner bottom have been put to practical use.

[Problem that the invention attempts to solve]

However, in the conventional pedestal as described above, since the inner bottom surface is funnel-shaped or sloped, the contact part with the round-bottomed container is only a line, so a sufficient stable holding effect has not yet been obtained. It was the actual situation.

On the other hand, if the inner bottom surface is curved, the contact part with the round-bottomed container becomes a surface, and as a result, an extremely excellent stable holding effect can be obtained. However, this method had the disadvantage that it could only hold round-bottomed containers with a diameter of one diameter.

Therefore, the present invention has been developed in order to solve these conventional drawbacks and to provide a pedestal that can stably hold round-bottom containers of multiple diameters on a single pedestal. We devised this invention which also has the following features.

[Means for solving problems]

That is, in the present invention, a through hole is formed in the center of a column whose curved inner bottom is concentrically formed in multiple stages, and an appropriate number of recesses are formed on the outer periphery of the outer bottom of the column. This is a pedestal for round-bottomed containers.

〔Example〕

The present invention will be further described below with reference to drawings showing an embodiment of the present invention.

Reference numeral 1 denotes a columnar body forming a seat, and although its specific shape is not limited, it is preferable to use a cylindrical body.

Reference numeral 2 denotes a curved inner bottom formed on the upper surface of the column 1, which is formed in a plurality of stages, usually 2 to 5 stages, in a concentric circle, and each stage is the same as the round bottom container. It forms a holding seat.

3 is a through hole formed in the center of the column 1;
It serves as a test tube stand. Note that the diameter of this through hole 3 is normally preferably about 20 mm.

Reference numeral 4 designates an appropriate number of recesses formed on the outer periphery of the outer bottom of the column 1, which serve as small test tube stands. Note that the diameter of this recess 4 is usually 8
mm, and the number is preferably about 4 to 8.

The material of the pedestal of this invention does not matter, but
For example, materials with a high coefficient of friction such as cork and hard rubber are preferred.

[Effect]

Since the present invention is constructed as described above, if the round-bottomed container 5 is placed on the inner bottom of the curved upper surface, the round-bottomed container 5 can be stably held by the surface contact action.

Furthermore, if the pedestal of the present invention is turned over so that the outer bottom is the upper surface, the test tube 6 can be inserted into the through hole 3 and the recess 4 to function as a test tube stand.

[Effect of idea]

Therefore, if the pedestal of the present invention is used, round-bottomed containers of various capacities (diameters) can be stably held in one pedestal by utilizing each curved inner bottom. Furthermore, by utilizing the through holes and recesses, a plurality of test tubes can be stably held.

Therefore, the present invention is particularly effective in laboratories and laboratories that use many types of round-bottomed containers such as flasks and test tubes, and which would otherwise become cramped if a stand was prepared for each.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is a perspective view thereof, FIG. 2 is a perspective view of the inverted state;
FIGS. 3 1 to 5 are explanatory longitudinal cross-sectional end views showing the state in which flasks of various capacities are mounted, and FIG. 4 is a perspective view showing the state used as a test tube stand.
