A funnel apparatus for filling of liquids, comprising: a funnel which has a liquid receiving member and a tubular member provided for carrying fluids; and a stopper which can be controlled manually by a handle to close the tubular member, to avoid the liquid to flow out from the funnel; and a tube to provide air ventilation; characterized in that: an end of the receiving member has a limiting portion that encompasses a circular area with an inner diameter of the receiving member; and the tubular member has a passageway and has a top portion and a bottom portion through which the fluid flows from the receiving member into a filling opening portion, whereby the limiting portion is provided in order for locking means to be locked thereon, and the tubular member is provided in order for being locked onto the filling opening portion of a liquid reservoir of an automobile; the locking means having an assembly bore and a rim, wherein the rim is connected to the assembly bore with a series of spokes, which are fixed at the limiting portion of the receiving member, wherein the assembly bore is plunged onto a connecting hub, which has an extending lip and a tubing, wherein the extending lip pushes against an end of the assembly bore, the tubing being tightly attached onto the inner diameter of the assembly bore; the funnel further comprising sealing means, wherein the sealing means comprise a plunger rod, wherein the plunger rod has a top end, a bottom end, and a recessed portion patterned in a longitudinal orientation, wherein the plunger rod has a plurality of slits disposed in a longitudinal orientation on an outer surface thereof, whereby the slits enable inspection of said tube, being a soft tube inserted in the recessed portion; and wherein the top end integrally broadens and is disposed with said handle and wherein the stopper is tightly attached onto the bottom end of the plunger rod of the sealing means wherein the bottom end of the plunger rod of the sealing means passes through the connecting hub, in such a way that the plunger rod can move axially on the locking means; said stopper acting as a valve for blocking or opening the tubular member; and wherein the soft tube has a long-strip shape and is inserted into the recessed portion of the plunger rod to pass through the stopper to stretch through the tubular member and traverse the funnel with a predetermined length of the soft tube reaching outside the funnel. a funnel which has a liquid receiving member and a tubular member provided for carrying fluids; and a stopper which can be controlled manually by a handle to close the tubular member, to avoid the liquid to flow out from the funnel; and a tube to provide air ventilation; an end of the receiving member has a limiting portion that encompasses a circular area with an inner diameter of the receiving member; and the tubular member has a passageway and has a top portion and a bottom portion through which the fluid flows from the receiving member into a filling opening portion, whereby the limiting portion is provided in order for locking means to be locked thereon, and the tubular member is provided in order for being locked onto the filling opening portion of a liquid reservoir of an automobile; the locking means having an assembly bore and a rim, wherein the rim is connected to the assembly bore with a series of spokes, which are fixed at the limiting portion of the receiving member, wherein the assembly bore is plunged onto a connecting hub, which has an extending lip and a tubing, wherein the extending lip pushes against an end of the assembly bore, the tubing being tightly attached onto the inner diameter of the assembly bore; the funnel further comprising sealing means, wherein the sealing means comprise a plunger rod, wherein the plunger rod has a top end, a bottom end, and a recessed portion patterned in a longitudinal orientation, wherein the plunger rod has a plurality of slits disposed in a longitudinal orientation on an outer surface thereof, whereby the slits enable inspection of said tube, being a soft tube inserted in the recessed portion; and wherein the top end integrally broadens and is disposed with said handle and wherein the stopper is tightly attached onto the bottom end of the plunger rod of the sealing means wherein the bottom end of the plunger rod of the sealing means passes through the connecting hub, in such a way that the plunger rod can move axially on the locking means; said stopper acting as a valve for blocking or opening the tubular member; and wherein the soft tube has a long-strip shape and is inserted into the recessed portion of the plunger rod to pass through the stopper to stretch through the tubular member and traverse the funnel with a predetermined length of the soft tube reaching outside the funnel.
