Description
【考案の詳細な説明】 本考案は、ふっ素樹脂容器の蓋用ガスケットに関する。[Detailed explanation of the idea] The present invention relates to a gasket for a lid of a fluororesin container.
ふっ素樹脂製容器は、腐食性液体などを貯蔵運搬する目
的に使用されるもので、最近特にシリコン半導体の洗浄
液に用いられてきている。Fluororesin containers are used for the purpose of storing and transporting corrosive liquids, and have recently been used particularly for cleaning liquids for silicon semiconductors.
この容器の蓋と本体との間には、ガスケットを装着し、
内部流体の漏洩を防止しているが、このガスケットは、
ゴムシートを中芯にしてふっ素樹脂フィルムで被覆した
槽底になっているため、ふっ素樹脂製容器本体とふっ素
樹脂製蓋との締付にあっては、十分な締付は力が付与で
きず、いわゆるフロー現象が生じる欠点がある。A gasket is installed between the lid and the main body of this container,
This gasket prevents internal fluid from leaking.
Since the bottom of the tank is made of a rubber sheet as the core and covered with a fluororesin film, it is not possible to apply sufficient tightening force when tightening the fluororesin container body and the fluororesin lid. , there is a drawback that a so-called flow phenomenon occurs.
そこで、本考案は上記欠点に鑑み考案されたもので、シ
ール性に優れしかも安価なふっ素樹脂製容器の蓋用ガス
ケットを提供するものである。The present invention was devised in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a gasket for the lid of a fluororesin container that has excellent sealing properties and is inexpensive.
図面について、本考案を具体的に説明する。The present invention will be specifically explained with reference to the drawings.
第１図は本考案のふっ素樹脂製ガスケットａを示すもの
で、該ガスケットａは、円環板状の基部１と該基部１の
外面には断面コ字状の舌片２，２とを一体に成形し、舌
片２，２内にはゴムＯリング３を介在しである。FIG. 1 shows a fluororesin gasket a of the present invention, which has an annular plate-shaped base 1 and tongue pieces 2, 2 each having a U-shaped cross section on the outer surface of the base 1. A rubber O-ring 3 is interposed inside the tongue pieces 2, 2.
この場合、舌片２，２内にゴムＯリング３を介在した厚
さ寸法は基部１の厚さ寸法より若干大きくすることが好
ましい。In this case, it is preferable that the thickness of the tongues 2, 2 with the rubber O-ring 3 interposed therebetween is slightly larger than the thickness of the base 1.
第２図は、ふっ素樹脂製容器を示すもので、この容器本
体４は、ふっ素樹脂製内壁５を塩化ビニル、ＦＲＰなど
の外壁６で補強してあり、液体注出口には、フランジ部
７を形成し、このフランジ部は前記内壁５、外壁６を延
長して形成されている。FIG. 2 shows a container made of fluororesin. The container body 4 has an inner wall 5 made of fluororesin reinforced with an outer wall 6 made of vinyl chloride, FRP, etc., and a flange portion 7 at the liquid spout. The flange portion is formed by extending the inner wall 5 and outer wall 6.
該フランジ部７にはふっ素樹脂製ガスケットａ及び、ふ
っ素樹脂製円板８と塩化ビニル、ＦＲＰ製の円板９とか
らなる蓋１０を載置し、ボルト１１にてガスケットａを
締付する。A gasket a made of fluororesin and a lid 10 consisting of a disk 8 made of fluororesin and a disk 9 made of vinyl chloride or FRP are placed on the flange portion 7, and the gasket a is tightened with bolts 11.
ふっ素樹脂製ガスケツ）ａは、ふっ素樹脂製内壁５のフ
ランジ部７と、蓋１０のふっ素樹脂製円板８との間にあ

部内径がフランジ部の内径に一致することによってフラ
ンジ部に液溜を防止し、また、ガスケットａの外径をボ
ルト内接することによってガスケットａの装着上におけ
る中心配置が可能となる。The fluororesin gasket a is located between the flange 7 of the fluororesin inner wall 5 and the fluororesin disk 8 of the lid 10 and is tightened, but the inner diameter of the base of the gasket a is the same as the inner diameter of the flange. By aligning with the diameter of the gasket a, liquid accumulation is prevented at the flange portion, and by inscribing the outer diameter of the gasket a with the bolt, it is possible to center the gasket a on the mounting surface.
尚、ふっ素樹脂製容器は図面に示す形状、構造に限定さ
れるものでなく、ふっ素樹脂のみにて槽底されたり、蓋
には、圧力流体を注入し、内部流体をその圧力で排出す
る槽底の容器も本考案の範囲に含まれるものである。Note that the fluororesin container is not limited to the shape and structure shown in the drawings, and may include a tank bottom made only of fluororesin, or a lid in which pressurized fluid is injected and the internal fluid is discharged at that pressure. The bottom container is also within the scope of the present invention.
本考案は、ふっ素樹脂製ガスケットの舌片内にゴムＯリ
ングを介在しであるので、フランジ部と蓋間に装着した
とき線状に大きな締付力が作用し少ない締付力で完全な
シール作用をすることができる。This invention uses a rubber O-ring inside the tongue of the fluororesin gasket, so when it is installed between the flange and the lid, a large linear tightening force is applied, creating a complete seal with less tightening force. can act.
また、ガスケットの基部によって締付は過剰を防止でき
るので、ガスケットのフロー現象を防止することができ
る。In addition, since excessive tightening can be prevented by the base of the gasket, a flow phenomenon of the gasket can be prevented.
さらにガスケットの形状が簡単であり、製作容易であっ
て安価なガスケットを提供できるなどの効果がある。Furthermore, the gasket has a simple shape, is easy to manufacture, and can be provided at low cost.
