Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a new desiccator inner lid, and more particularly to a desiccator inner lid suitable for cooling and drying when a hot substance is put in the desiccator.

[0002]

[Prior art]

 When a hot object is left to cool in dry air, if the hot object is put into the desiccator as it is, the air in the desiccator is heated and expands, so the expanded air lifts the lid and moves it sideways or comes off. I have something to do. For this reason, conventionally, the lid is partially dried and air-expansion is stopped, and then closed, or a tube containing a desiccant is connected to a desiccator to cool and dry.

However, the method of opening a part of the lid has a problem that it takes time until the expansion of air is stopped, and the method of connecting a tube containing a desiccant cannot maintain a dry state for a long time.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a new desiccator inner lid which can easily perform cooling and drying of a high temperature object using an ordinary desiccator. To do.

[0005]

[Means for Solving the Problems]

 The above object of the present invention is to provide a desiccator inner lid including a ring-shaped outer peripheral portion that can be sandwiched between a desiccator main body and a desiccator lid, and a heat-resistant and flexible sheet-shaped material that is attached to the inside of the desiccator lid. To be achieved.

In the present invention, the ring-shaped outer peripheral portion is not particularly limited in shape such as thickness and width as long as it has a shape sandwiched between the desiccator main body and the desiccator lid. An "L-shaped" or "T-shaped" locking portion is preferably formed so that the outer peripheral edge can be locked to the outside of the desiccator main body because there is no risk of shifting during use. The outer peripheral portion does not need to have heat resistance.

The heat-resistant sheet material according to the present invention has a heat resistance level of class B or higher. Examples of such a material include polyester film, polyimide film, and cloth filled with fluororesin. it can. Further, the sheet-like material according to the present invention has good flexibility, and more preferably has excellent stretchability.

The above-mentioned sheet-shaped article may be worn in a taut state on the above-mentioned outer peripheral portion as long as it is excellent in stretchability, but in general, it is not a plane-shaped article but a lower one. A curved surface that hangs down is preferable because it can easily follow the thermally expanded air volume. Further, the thickness of the sheet-like material is not particularly limited as long as it has flexibility enough to easily cope with the increased air volume.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

Embodiment 1 FIG. 1 is a plan view showing an embodiment of an inner lid for a desiccator of the present invention, and FIG. 2 is an assembly cross-sectional explanatory view when the inner lid for a desiccator is attached to the desiccator. The desiccator inner lid 4 has an outer peripheral portion 1 having a ring shape having substantially the same shape as the joint portions 7 and 7 ′ of the desiccator body 5 and the desiccator lid body 6 and having a thickness of about 1 mm. In this embodiment, the outer edge of the outer peripheral portion 1 is formed with a "T-shaped" engaging portion 3 that can be engaged with the outer periphery of the joint portions 7, 7 '. A thin curved sheet-like material 2 having heat resistance and flexibility is worn inside the outer peripheral portion 1.

In order to cool and dry a high temperature object by using the desiccator inner lid 4, the following procedure may be performed. First, the high temperature object 8 is placed on the shelf plate 9 of the desiccator main body 5, and then the engaging portion 3 of the desiccator inner lid 4 is engaged with the outer edge portion of the joint portion 7, so that the desiccator main body 5 can be secured. After closing the opening with the desiccator inner lid 4, the desiccator lid 6 is covered from above. At this time, the engaging portion 3 of the desiccator inner lid 4 is engaged with the outer edge portion of the joint portion 7'of the desiccator lid body 6 as in the desiccator main body 5.

Embodiment 2 FIG. 3 is a perspective view showing another embodiment of the present invention, and FIG. 4 is a sectional view taken along the line XX '. The device of this embodiment has the same structure as that of the first embodiment, except that the locking portion is not formed on the outer edge of the outer peripheral portion 1.

When the engaging portion is formed on the outer edge of the outer peripheral portion 1, the desiccator inner lid 4 is firmly clamped and fixed, but the object of the present invention is sufficient without the engaging portion. Can be achieved. The locking portion may be formed so that it can be locked to either the desiccator main body or the desiccator lid.

[0014]

[Action]

 FIG. 5 is a cross-sectional explanatory view showing the inside of the desiccator when the high temperature material 8 is stored in the desiccator using the desiccator inner lid 4 shown in FIG. 1. FIG. FIG. 6 is a cross-sectional explanatory view showing a state of the desiccator inner lid 4 when the air is heated.

When the high-temperature material 8 is stored in the desiccator, the air therein is warmed and gradually expanded, but the volume of air increased by the expansion is absorbed by the sheet-shaped material 2 expanding upward. . Therefore, the pressure inside the desiccator hardly rises, and the desiccator lid 6 is not lifted and laterally displaced or disengaged. Incidentally, since the plug hole 10 in the upper portion of the desiccator lid 6 is open, naturally this portion is at atmospheric pressure.

[0016]

[Advantage of the Invention] The novel inner lid for a desiccator of the present invention has a sheet-like material having heat resistance and flexibility, so that even if the air in the desiccator thermally expands, its volume can be easily increased. The pressure rise in the desiccator can be prevented in advance. Therefore, when the desiccator-like inner lid of the present invention is used, even if a high-temperature object is put in the desiccator, the lid does not lift up and shift sideways or come off. It is possible to cool and dry.
