Abstract
A resinous connector includes a flange-shaped base, a nipple, an O-ring, and an O-ring groove. The nipple extends from the base, and has an outer peripheral surface and sealing projections disposed on the outer peripheral surface. The sealing projections have a substantially triangle-shaped cross section whose diameter reduces in the direction away from the base. The O-ring is disposed between the nipple and a hose. The O-ring groove is formed at a root of the nipple in the outer peripheral surface, and is disposed at a position closer to the base than the sealing projection disposed in most proximity to the base. The resinous connector can inhibit the O-ring from being twisted or bruised by the hose.
Claims9
A resinous connector, comprising:
- a flange-shaped base welded to a resinous container having an opening so as to cover the opening;
- a nipple extending from the base, fitted into a hose by press-in fitting, and having an outer peripheral surface fastened to the inner peripheral surface of the hose and sealing projections disposed on the outer peripheral surface, the sealing projections having a substantially triangle-shaped cross section whose diameter reduces in the direction away from the base;
- an O-ring disposed between the outer peripheral surface of the nipple and the inner peripheral surface of the hose, and sealing therebetween;
- and
- an O-ring groove formed at a root of the nipple in the outer peripheral surface thereof, and disposed at a position closer to the base than the sealing projection disposed in most proximity to the base.
A resinous connector, comprising:
- a flange-shaped base welded to a resinous container having an opening so as to cover the opening;
- a nipple extending from the base, fitted into a hose by press-in fitting, and having an outer peripheral surface fastened to the inner peripheral surface of the hose and sealing projections disposed on the outer peripheral surface, the sealing projections having a substantially triangle-shaped cross section whose diameter reduces in the direction away from the base;
- an O-ring disposed between the outer peripheral surface of the nipple and the inner peripheral surface of the hose, and sealing therebetween;
- the base comprising an outer periphery, and the nipple comprising a root extending from the base and having an outer periphery, at least the outer periphery of the base and the outer periphery of the root being formed of a first resin which is weldable to the container;
- and
- the nipple further comprising a leading portion disposed ahead of the root, at least the leading portion being formed of a second resin whose rigidity is higher than that of the first resin, and an O-ring groove formed in a surface adjacent to the root of the nipple or in the surface of the root.
