配されている。[Prior Art] Most of the caps of steel drum containers are of the press-fit internal thread type.
Since there is a drawback that zinc alloy die-casting powder, iron powder, plating pieces, paint chips, etc. fall into the container, an external screw type cap 1 as shown in Fig. 3 has recently been developed and put into use. There is. In the figure, 2 is a top plate, 3 is an access port formed by partially opening the top board 2 in a circular shape and raising the area around the opening, 4 is an external threaded ring attached to the outside of the access port 3, and 5 is a Inlet/outlet 3
6 is a plug screwed onto the externally threaded ring 4. At the center of the packing 5, a knob ring 5a is arranged integrally with a connecting piece 5c.

削り滓が容器内に落ち込むものである。[Problems to be solved by the invention] By the way, as shown in FIGS. 4a and 4b, the gasket 5 used in the external thread type cap 1 has a planar flange 5b at the upper end periphery. When the plug 6 is tightened to the outer threaded ring 4 as shown in FIG. 4
Pressure force due to tightening is small. Therefore, the seal between the flange 5b and the upper edge of the access port 3 is incomplete, and the contents leak due to vibrations and impacts during transportation. In addition, the temperature of the contents is higher than the outside air at the time of filling, and the pressure inside the container decreases due to temperature drop during storage or transportation, and the packing 5 due to vacuum action.
The flange 5b slips into the opening and becomes unsealable and communicates with the outside, allowing dirt and the like to be absorbed. Further, when the plug 6 is tightened to the outer threaded ring 4, the packing 5 rotates together, and the shavings of the packing 5 caused by friction with the inlet/outlet 3 and its upper periphery fall into the container.

It is an object of the present invention to provide a gasket that does not slip into place and also does not rotate when a plug is tightened.

The part is completely sealed. Then, when the plug is screwed in, the gasket does not rotate together, and the annular convex portions on the upper and lower surfaces of the flanges of the gasket are compressed, tightly adhering to the upper edge of the opening and the inner edge of the plug top plate, creating a complete seal. be done.
That is, when the plug is screwed, since the flange has annular convex portions on the upper and lower surfaces, it linearly adheres to the upper edge of the entrance and the inner edge of the upper plate of the plug, and the tightening force in the circumferential direction is approximately It becomes uniform, and the adhesion force due to the tightening of the plug per unit area is large. Therefore, the seal between the flange and the upper edge of the opening and the inner edge of the upper plate of the plug is perfect, and the contents will not leak out due to vibration or impact during transportation. In addition, even if the temperature of the contents becomes lower than during filling and the inside of the container is depressurized and the vacuum effect is activated, the annular protrusion on the outer circumferential surface of the middle part of the seal and the annular protrusion on the upper and lower surfaces of the flange will adhere strongly as described above. Since the frictional resistance is large, there is no possibility of the door being pulled in and out, and the seal is perfect, preventing dirt from being absorbed from the outside.

10.3 mm, the outside diameter of the flange 5b is 66.2 mm, and the thickness is 1.5 mm.
An annular protrusion 10 with a semicircular cross section of 0.8 mm in height is integrally provided on the lower surface of the outer peripheral edge of the flange 5b. An annular convex portion 12 with a semicircular cross section and a height of 0.8 mm is integrally provided on the outer peripheral surface at a height of 6.5 mm from the bottom surface.

出することが無かつた。 The externally threaded plug packing 5 configured as described above is used, for example, in an externally threaded cap 1 of an 18 capacity steel drum container filled with 113 kg of fluorocarbons as shown in FIG.
When the packing 5 was fitted into the opening 3 having a diameter of 70 mm, the annular convex portion 12 on the outer periphery of the middle part of the packing 5 was compressed and tightly adhered to the inner circumferential surface of the opening 3, thereby sealing the part. Then, when the plug 6 is screwed in as shown in the figure, the gasket 5 does not rotate together, and the inlet/outlet 3
This made it possible to prevent the generation of shavings on the packing 5 due to friction between the opening 3 and the packing 5.
At the same time as the former packing 5 is pushed in, the annular convex portions 10 and 1 on the upper and lower surfaces of the outer periphery of the flange 5b of the packing 5
1 was compressed and tightly adhered to the upper edge of the inlet/outlet 3 and the inner edge of the upper plate of the plug 6, thereby completely sealing these parts. In this way, the cap 1 had a complete two-stage seal, so that even if the steel drum container containing fluorocarbons was subjected to vibrations or shocks during transportation, no fluorocarbons would leak out.

りごみ等が吸収されることがなかつた。 In addition, even if the temperature of the fluorocarbon during transportation and storage becomes lower than when it is filled into the steel drum container, the pressure inside the steel drum container is reduced, and a vacuum effect is activated, the outer circumferential surface of the middle part of the packing 5 will be annular. The convex portion 12 is tightly attached to the inner circumferential surface of the inlet/outlet port 3, and the annular convex portions 10, 11 on the upper and lower surfaces of the outer circumferential edge of the flange 5b are tightly attached to the inner circumferential edge of the upper plate of the plug 6 and the upper end circumferential edge of the inlet/outlet port 3. Since the frictional resistance is large and the flange 5b is not easily deformed due to the annular convex portions 10 and 11 on both the upper and lower surfaces, the packing 5 is not drawn into the loading/unloading opening 3, and the seal is perfect and dirt etc. are absorbed from the outside. I was bored.

手間がかからない。 However, when the user uses the Freon in the steel drum container in small portions, the inlet/outlet 3 is
Since the annular convex portion 12 on the outer periphery of the middle portion of the plug 6 can provide a complete seal, the plug 6 does not need to be used while being removed. Therefore, opening and closing the loading/unloading port 3 is easy and requires no effort.

The annular convex portions 10 and 11 on the upper and lower surfaces of the seal 5 and the annular convex portion 12 on the middle and high portion of the packing 5 have a semicircular cross section, but are not limited to this, and may have a triangular cross section. Further, the annular convex portions 10 and 11 are connected to the flange 5b.
Although it is provided on the outer peripheral edge of the flange 5b, it is not limited to this, and may be provided in the middle of the flange 5b. Further, small protrusions are formed at equiangular square positions on the outer periphery of the flange 5b of the seal 5, the seal 5 is inserted into the plug 6, the protrusions are engaged with the upper end of the inner surface of the threaded part of the plug 6, and the seal 5 is attached to the plug 6. If attached, it will be easy to seal the cap after filling the steel drum container with the contents, and the plug 6 will also be included.
When it is rotated and removed, the gasket 5 firmly adheres to the inlet/outlet 3, so it does not rotate together and the seal is perfect, preventing dirt from entering.

である。[Effects of the invention] As can be seen from the above explanation, the packing for the external threaded plug of the steel drum container of the present invention has a perfect seal with the mouthpiece of the mouthpiece, and is able to withstand vibrations and impacts on the contents inside the container. No leakage to the outside. In addition, even if there is a vacuum effect due to the reduced pressure inside the container, it will not slip into the loading/unloading opening, so the seal is perfect and no dust or the like will be sucked in from the outside. Furthermore, even when the plug is tightened, it does not rotate, so no shavings from the packing are generated, and the filling inside the container can be stored cleanly without falling into the container. Therefore, it is extremely useful as a gasket for an externally threaded plug of a steel drum container filled with materials that do not want to be contaminated with fine particles of about 5 μm such as semiconductor cleaning solvents such as chlorofluorocarbons.
