Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to test tubes (herein,
This term is used as a general term for various types of tubes, bottles, cups, containers, etc.).

[Conventional technology]

Conventional test tube stand units of this type generally consist of a box with an open top, as shown in the overall longitudinal sectional front view of FIG. A base box member P in which a number of recesses p capable of supporting are formed on the bottom surface, and a test tube S can be inserted in an upright position, and each upper part of the inserted test tube S is horizontally A plate member Q is formed of a horizontal plate-like member in which a large number of supportable holes q are formed, and is formed to be removably fitable at a predetermined height position within the base box member P; It consisted of a lid member R made of a plate that can be freely fitted and removed from the upper peripheral edge of the base box member P.

[Problem that the invention attempts to solve]

However, in the test tube stand unit having the above conventional configuration, the height of the base box member P itself and the height of the plate member Q from the bottom of the base box member P are limited.
Since the height of the test tube S is always constant, the test tube stand unit can only be applied to test tubes S of a certain length, resulting in a problem of poor versatility. In other words, we have a dedicated test tube stand unit for long test tubes, a dedicated test tube stand unit for short test tubes, and so on to accommodate test tubes of various lengths. It is necessary to prepare test tube stand units with various heights, which is extremely wasteful and uneconomical both in terms of manufacturing and use, and is also inconvenient to use and wastes storage space. The disadvantage was that it was easy for this to occur.

The present invention was developed in view of the conventional problems mentioned above, and its purpose is to develop and develop a highly versatile test tube stand unit that can be applied to both long and short test tubes. This is what we aim to provide.

[Means for solving problems]

In order to achieve this purpose, the test tube stand unit according to the present invention, as shown in the basic configuration diagram (diagram corresponding to the claims) in FIG. A horizontal plate-like member which is formed with a large number of holes b into which test tubes S can be inserted in an upright position and which can support each inserted test tube S in the horizontal direction; The first plate member B is formed so that it can be detachably fitted onto the upper end peripheral part of the bottom cover member A at the lower end peripheral part of the first plate member B.
and a spacer member C which is formed of a frame with an upper and lower opening, and which is formed so that it can be detachably fitted onto the upper end peripheral edge of the first plate member B at the lower end peripheral edge of the frame. , consisting of a horizontal plate-like member in which a large number of holes d are formed, into which test tubes S can be inserted in an upright position, and each of the inserted test tubes S can be supported in the horizontal direction; A second plate member D is formed to be able to be attached to and detached from the upper end of the spacer member C at the lower end of the member; and a box with an opening at the bottom; An upper lid member E is formed at the lower end peripheral portion to be detachably attached to the upper end peripheral portion of either the first plate member B or the second plate member D. It has characteristics.

[Effect]

The effects exhibited by the above characteristic configuration are as follows.

That is, according to the test tube stand unit according to the present invention, as shown in FIG. It can be suitably used for test tubes S..., and on the other hand, as shown in FIG. If used in this case, it can be suitably used for short test tubes S... As described above, according to the present invention, although it is a single test tube stand unit, it is possible to obtain a very versatile test tube stand unit that can be suitably used for both long and short test tubes. be able to.

It should be noted that if multiple types of spacer members C of different heights are prepared, by replacing them as appropriate, this test tube stand unit can be used for test tubes of a wider variety of lengths. Each can be suitably used.

Further, the first plate member B and the second plate member D each have holes b of different sizes.
If you prepare multiple types of test tube stand units with ..., d..., you can replace them as appropriate to make this test tube stand unit suitable for test tubes of various thicknesses, or for upper and lower parts. Therefore, it is possible to suitably use test tubes having different diameters.

Furthermore, if the bottom cover member A and the top cover member E are formed to be vertically symmetrical to each other, that is, to have the same shape, manufacturing costs can be significantly reduced.

C is a spacer member that is integrally formed by injection molding of a relatively hard transparent or translucent synthetic resin material (such as hard polypropylene), and is provided inside the upper and lower peripheral edges, respectively. It consists of an upper and lower opening type frame having a cutout-like step and a rectangular frame in plan view, and the upper end peripheral edge of the first plate member B (that is, the upper vertical Frame part 2
It is configured so that it can be freely fitted and removed from the outside.

Furthermore, D is a second plate member having the same shape and configuration as the first plate member B, which is integrally formed by injection molding of a relatively hard colored synthetic resin (such as hard polypropylene), and is made of a plurality of test tubes. A horizontal plate portion 3 in which a large number of holes d are formed into which test tubes S can be inserted in an upright position and each of the inserted test tubes S can be supported in the horizontal direction, and a peripheral edge of the horizontal plate portion 3. An upper vertical frame portion 4a and a lower vertical frame portion 4b are integrally connected vertically from
It consists of a horizontal plate-like member having a rectangular shape in plan view,
In addition, the horizontal plate-shaped member is configured to be able to be removably fitted into the stepped portion of the lower end periphery of the spacer member C at the lower end periphery (that is, the lower vertical frame portion 4b). .

Furthermore, E is a top lid member having a vertically symmetrical configuration with the bottom lid member A, and is integrally formed by injection molding of a transparent or translucent relatively soft synthetic resin material (for example, soft polypropylene). It is a box with an open bottom and a rectangular shape in plan view, and has an outwardly expanding step at the lower peripheral edge. The stepped portion of the lower end peripheral edge of the box body can be freely fitted into and removed from the upper end peripheral edge of either the first plate member A or the second plate member D (that is, the upper vertical frame portion 2a or 4a). It is configured so that it can be fitted externally.

By the way, FIG. 3A shows a plan view of the first and second plate members B and D at the same time, and FIG. 3B shows a longitudinal sectional side view (a view taken along the - line). Further, FIG. 4A shows a plan view of the spacer member C, and FIG. 4B shows a longitudinal sectional side view (view taken along the - line). Furthermore, Fig. 5A shows
A bottom view of the bottom cover member A and a plan view of the top cover member E are shown at the same time, and FIG.

As is clear from these figures, the first and second plate members B and D have, on the outer circumferential surfaces of their upper vertical frame portions 2a and 4a and the outer circumferential surfaces of their lower vertical frame portions 2b and 4b, respectively. A plurality of (four in this example) engaging protrusions 5..., 6... are formed on the inner surface of the upper peripheral edge of the spacer member C, on the lower side of the second plate member D. Engagement recesses 7 corresponding to the engagement protrusions 6 are formed, and engagement recesses 8 corresponding to the upper engagement protrusions 5 of the first plate member B are formed on the inner surface of the lower peripheral edge thereof. Furthermore, the bottom cover member A and the top cover member E include:
Each corresponds to the lower engaging protrusion 6 of the first plate member B (the upper engaging protrusion 5 of the first plate member B or the second plate member D) on the inner surface of the upper end (lower end) peripheral edge thereof, respectively. Engagement recesses 9 are formed to ensure a firm fit between the respective constituent members. Note that various modifications are possible, such as forming engaging recesses on the first and second plate members B and D, and forming engaging protrusions on the spacer member C, bottom cover member A, and upper cover member E. Further, if the sizes of each component are set with high precision, there is no problem in practical use even if these engaging projections and recesses are not particularly provided.

Now, when the test tube stand unit configured as described above is used for a relatively long test tube S..., as shown in FIG. , D, and E. On the other hand, when used for short test tubes S..., as shown in FIG. 6, with spacer member C and second plate member D removed, In other words, it is sufficient to assemble only the constituent members A, B, and C.

In addition, if a plurality of types of spacer members C with different heights are prepared, it is possible to accommodate test tubes with a wider variety of lengths.

In addition, as shown in FIG. If they are made different from each other, as illustrated by the dotted line in FIG. 6, by fitting the first plate member B (second plate member D) upside down, the horizontal plate portion 1 can be , 3 can be changed, so test tubes of a wider variety of lengths can be accommodated.

Furthermore, the first plate member B and the second plate member D each have holes b of different sizes.
If a plurality of types having..., d... are prepared, it is possible to not only deal with test tubes having various thicknesses, but also with test tubes having shapes where the upper and lower portions have different thicknesses.

Furthermore, in this embodiment, the bottom cover member A and the top cover member E are formed to be vertically symmetrical to each other, that is, to have the same shape,
Since the first plate member B and the second plate member D are formed to have the same shape,
Although it consists of a relatively large number of structural members, the number of types of molds for molding can be minimized,
Therefore, manufacturing costs can be significantly reduced.

By the way, as shown in FIGS. 5A and 5B, on the lower surface of the bottom cover member A and the upper surface of the upper cover member E, for example, during storage or autoclaving, there are a plurality of When stacking test tube stand units, a plurality of hook-shaped protrusions 10a, 10 (in this example, 4 in total, 1 at each corner) are provided in order to prevent mutual displacement.
a, 10b, 10b are formed. Among these, a pair of diagonally opposite ones 10a, 1
0a is provided closer to the outermost side of each corner, and the other pair 10b, 10b are provided slightly closer to the inner side than the outermost side of each corner. In other words, when a plurality of test tube stand units are stacked as shown in FIG. 7, the outer projections 10a, 10a on one test tube stand unit side and the inner projections 10b, 10b on the other test tube stand unit side are They are configured to engage with each other.

FIG. 8 shows another embodiment, and in the case of the above embodiment, the bottom cover member A, the spacer member C, and the top cover member E are fitted onto the first plate member B or the second plate member. On the other hand, in this example, the fitting state is configured to have the opposite relationship as shown in the figure.

Further, in this example, a plate-shaped sponge member or a plate-shaped filter paper member H for holding test tubes is removably fitted into the inner upper part of the upper lid member E. By doing this, you can not only effectively prevent test tubes from being damaged during transportation, but you can also turn the entire test tube stand unit upside down to effectively dry test tubes. It is convenient for

Since the other configurations are basically the same as those of the above embodiment, members having the same functions are given the same reference numerals, and the explanation thereof will be omitted.
