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.
A nozzle for an inflatable object being made of a plastic material, comprising: a nozzle seat which is retractable into said inflatable object upon pressing and extendable from a surface of said inflatable object only when being pulled out for inflation of said inflatable object; an annular wall extended from said nozzle seat which defines an air inlet for air; a plug which is insertable into said air inlet; a plug arm extending from said annular wall and connecting said plug with said nozzle seat; and a piece of one-way membrane extending from a lower inner face of said nozzle seat and allowing air to flow in through said air inlet during inflation but blocking air from flowing out from said air inlet when said nozzle seat is extended from a surface of said inflatable object.
