The protective cover 1 has a window part 2 through which a grip of the jig is to be passed. The protective cover 1 is made of a transparent or translucent resin. A peripheral edge of the protective cover 1 is positioned on the side of the head with respect to an intermediate position of the length of the grip of the jig during the opening/closing of the cap.

Description

  The present invention relates to a cap opening / closing jig protective cover capable of ensuring safety when opening and closing a cap of a container filled with a dangerous substance or the like.

  Conventionally, jigs having various properties (for example, a drum wrench, a drum spanner, etc.) have been proposed and sold in order to increase work efficiency when opening and closing a cap of a general drum can (for example, Patent Document 1 and 2).

However, when opening a drum can in which waste is sealed, there is a risk of not only the shape but also the ejection of the contents due to full filling. Therefore, it is important to ensure the safety of the operator by preventing liquid and chemical damage even if the contents are ejected.

Japanese Utility Model Publication No. 6-15971 Japanese Utility Model Publication No. 63-147268

In conventional opening and closing operations of drums and the like, measures have been taken for workers to wear protective glasses, safety gloves, etc. so that the workers will not be exposed to liquid even if the contents are ejected.
However, when the contents are ejected, there is a possibility that the contents may adhere to other than the protection site, and the workability of the protective clothing covering the whole body is remarkably lowered, so that there is a problem that it cannot be practically adopted.
The present invention has been made in view of the above-described problems of the prior arts, and an object of the present invention is to find a cover that can ensure the safety of opening and closing operations without deteriorating workability, and to complete the present invention.

  In order to solve the above-described problems, the present invention provides a cap opening / closing jig protective cover that covers the periphery of a wrench head, which is a work location, with a protective cover.

That is, the cap opening / closing jig protective cover of the present invention has a shape of a portion excluding the bottom surface from one type selected from a cone, a truncated cone, a polygonal pyramid, and a polygonal truncated cone, The surrounding area is covered with an umbrella.

  As described above, by using the protective cover for the cap opening / closing jig of the present invention, the protective cover covers the wrench head around the work location, so that the operator can be safely opened and closed by protecting the liquid from splashing when the cap is opened and closed. It became possible to do.

It is the top view and side view which show an example of this invention product. It is a photograph which shows the use condition of this invention product.

The cap opening / closing jig protective cover of the present invention is formed in a shape excluding the bottom surface such as a cone, a truncated cone, a polygonal pyramid, and a polygonal truncated cone, and the jig head used at the time of opening and closing the cap and its periphery are covered in an umbrella shape. It will be. With such a configuration, it is possible to perform a safe opening / closing operation by protecting the operator from the liquid splashed when the cap is opened / closed.

Further, since the cap is opened and closed by rotating the jig in the same plane as the cap installation surface, the protective cover of the present invention can be fixed to the jig. In this case, it is preferable to provide a window part in a part of the protective cover and pass the grip of the jig through the window part. By providing the window portion, it is possible to quickly and easily attach and detach the jig. Moreover, it can prevent that the protective cover which became unstable at the time of work remove | deviates from the cap periphery. As long as the size of the window does not affect workability, it is preferable to prevent scattering from the gap in accordance with the grip diameter.
For example, it is possible to mount a window portion having a width of about 40 mm and a height of about 10 mm through an openable and closable opening.

Furthermore, in order to ensure visibility during work, the protective cover of the present invention is preferably made of a transparent or translucent resin. As a result, the cap and the opening / closing jig gripping portion can be safely opened and closed by visual confirmation.
Examples of such a resin include polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), and polycarbonate (PC). Moreover, in order to make workability | operativity favorable, resin which is excellent in flexibility is good.

In addition, it is desirable that the size of the protective cover of the present invention does not significantly reduce the work efficiency compared to the case where a normal cap opening / closing jig is used. For this reason, when the cap is opened and closed, the peripheral edge of the protective cover is preferably located to a certain extent on the head side from the middle position of the grip length of the opening and closing jig.
Specifically, for example, a wrench for a drum can has a total length of about 200 mm to 300 mm, and can fully cover the drum can cap in a working state where the wrench is attached to the cap, and more than half of the wrench grip can be covered. The size should not be covered.

Furthermore, the protective cover of the present invention preferably has a peripheral edge extending downward from the cap installation surface. Thereby, the safety from after the cap is attached during the opening / closing operation to after the opening / closing can be further enhanced.
In addition, since the cap shape and size of a drum can etc. are not uniform, it is desirable to design the above-mentioned size and shape so that it becomes a protective cover which can be used in common with them.

A transparent polyethylene resin having a radius of 200 mm and a height of 70 mm was removed from the bottom, and a 40 mm × 5 mm window was provided on the side to provide a protective cover of this example. A schematic diagram is shown in FIG.
A grip of a ratchet wrench was passed through the window portion 2 of the protective cover 1, and the cap gripping portion of the wrench was set on the cap of the drum can to perform the opening / closing operation. This is shown in FIG.
The cap opening / closing operation using the protective cover as an example of the present invention product allows the cap gripping portion and the cap to be fixed visually, and the work efficiency is not lowered even when compared to when the cover is not attached. I was able to open the drum cap safely.
On the other hand, when the opening / closing operation is performed only with the opening / closing jig as a conventional method, there is a risk that the contents are scattered to the surroundings at the time of ejection, and the operator may be burned.

As described above, by using the opening / closing jig protective cover according to the present invention, the scattering range of the contents can be kept within a small range immediately after opening / closing, and the work can be performed more safely.
