Abstract: A nozzle for inflatable objects being made of a plastic material, including a nozzle body and a sealing element composed of a vertical sleeve body and an one-way membrane, in which the nozzle body is incorporated with an annular nozzle seat, a conical wall is extended upward from the annular nozzle seat, an annular horizontal wall is extended from the top of the conical wall, a vertical cylindrical body is extended from the annular horizontal wall, an air passage is formed in the vertical cylindrical body, a plug which can be inserted to the air passage to seal the air passage, the sealing element is tightly fitted to the lower cylindrical body, and an one-way membrane is secured to the inner wall of the sealing element to swing freely therein and to close the air passage tightly.

Abstract: An improved nozzle for inflatable objects including a nozzle seat, a first annular wall extending from which, a relatively thin ring portion on the first annular wall to serve as a bending position, a conical body defining an air inlet located on the ring portion, an one-way membrane beneath the air inlet, a tab and a plug arm carrying a plug and having a protuberance at an end for inserting to the air inlet to push away the one-way membrane for deflation purpose.

Abstract: A nozzle for inflatable objects, made of a plastic material, including a nozzle seat adapted to engage with the inflatable object, a first annular wall extending from the nozzle seat, a relatively thin ring portion formed at top end of the first annular wall, a second annular wall extending from the ring portion to define an air inlet, a plug for blocking air inlet, a plug arm extending from second annular wall and connecting the plug with second annular wall, a plug extension formed with a projection and extended from the plug at a position remote from plug arm, a tab formed with a hole and located at a side of air inlet opposite plug arm, and a one-way membrane extending from first annular wall, which during inflation allows air to blow through air inlet into the inflatable object, whereby after inflation, the plug is fitted into air inlet and the nozzle is retracted into the inflatable object with first bent portion bent downward, while when deflating, the plug is drawn out of air inlet and the nozzle is f

Abstract: A nozzle for inflatable objects being made of a plastic material, including a nozzle seat which is subject to engage with the inflatable object in such a manner that it is normally retracted in the inflatable object but also being extendable from the surface of the inflatable object when being pulled out; and annular wall extended from the nozzle seat which defines an air inlet; a plug for insertion into the air inlet; a plug arm extended from the annular wall and connecting the plug with the nozzle seat; a plug extension extended from the plug at a position remote from the plug arm and having two holes; a tie at a side of the air inlet opposite the plug arm being passable through the two holes on the plug extension; and a piece of one-way membrane extended from a lower face of the nozzle seat which during inflation allows air to blow in through the air inlet but which blocks air from flowing out of the air inlet when the nozzle seat is protruded from the surface of the inflatable object.
