The mouth of the device includes a plurality of hinge points that permit circumferential enlargement of the aperture, thereby allowing the device to form a substantially leak-proof frictional engagement with the neck of fuel additive containers having different diameters. In this manner devices can be used with almost all additive containers, regardless of the type, size and/or manufacturer. The device may include at least one flexible region on the nozzle. ## Claims ### Claim 1 A pourable matter delivery system including: A. A container having a neck defining an opening; and B. A pouring device having a distal pouring end and a proximal attaching end detachably engaged with said neck, said pouring device including: i. an elongated nozzle having a flexible region surrounded by two rigid regions, and a fixed circumference at said distal end, ii. an angled transition positioned contiguous to said elongated nozzle, iii. a plurality of inwardly angled hinge points positioned contiguous to said angled transition, and iv. a singular flange positioned contiguous to said plurality of inwardly angled hinge points and forming a terminus of said proximal attaching end, said singular flange defining an aperture and deformable for creating a frictional, non-leakage, releasable hold on said neck, wherein said singular flange is angled in a direction away from said nozzle when said pouring device is attached to said container, and said singular flange is angled in a direction towards said nozzle upon insertion of said neck into said aperture. ### Claim 2 (depends on 1) The pourable matter delivery system of claim 1 wherein said neck includes outwardly directed threads. ### Claim 3 (depends on 2) The pourable matter delivery system of claim 2 wherein said singular flange is engaged with said threads. ### Claim 4 (depends on 1) The pourable matter delivery system of claim 1 wherein said plurality of inwardly angled hinge points are rectangular. ### Claim 5 (depends on 4) The liquid pourable matter delivery system of claim 4 wherein said plurality of inwardly angled hinge points consists of between 4 and 60 hinge points. ### Claim 6 (depends on 5) The liquid delivery system of claim 5 wherein said plurality of inwardly angled hinge points consists of 6 hinge points. ### Claim 7 A pourable matter delivery device with a distal pouring end and a proximal attaching end including: A. A nozzle having a flexible region surrounded by two rigid cylindrical regions and defining an elongated hollow portion for pouring, said nozzle having a fixed circumference at said distal end; B. An angled transition positioned contiguous to said nozzle; C. A plurality of inwardly angled hinge points positioned contiguous to said angled transition; and D. A singular annular flange positioned contiguous to said plurality of inwardly angled hinge points and forming a terminus of said proximal attaching end, said singular annular flange defining an aperture and deformable to create a frictional, non-leakage, releasable hold with a neck of a container, wherein said singular annular flange is angled in a direction away from said nozzle when said pouring device is not attached to the container, and said singular annular flange is angled in a direction towards said nozzle upon insertion of the neck into said aperture. ### Claim 8 (depends on 7) The pourable matter delivery device of claim 7 wherein said elongated hollow portion has a smaller diameter than said aperture. ### Claim 9 (depends on 7) The pourable matter delivery device of claim 7 wherein said two rigid cylindrical regions each have a diameter of 20.57 mm. ### Claim 10 (depends on 7) The pourable matter delivery device of claim 7 wherein said aperture has a diameter of 19 mm to 25 mm. ### Claim 11 (depends on 10) The pourable matter delivery device of claim 10 wherein the diameter of said aperture can be enlarged by 10% without damaging the structural integrity of said single annular flange. ### Claim 12 (depends on 7) The pourable matter delivery device of claim 7 being constructed of materials selected from the group consisting of high density polyethylene, low density polyethylene and combinations thereof. ### Claim 13 A device with a distal pouring end and a proximal attaching end for introducing substances into capless fuel systems, said device including: A. A nozzle sized and shaped to bypass a capless fuel system's opening flap; B. An angled transition position contiguous to said nozzle; C. A plurality of double-acting hinge points angled inwardly towards said nozzle and contiguous to said angled transition; and D. An annular flange positioned contiguous to said plurality of double-acting hinge joints and forming a terminus of said proximal attaching end, said annular flange defining an aperture and deformable to create a frictional, non-leaking, detachable engagement with a neck of a container, wherein said annular flange is angled in a direction away from said nozzle when said device is not attached to the neck, and said annular flange is angled in a direction towards said nozzle upon complete insertion of said neck into said aperture. ### Claim 14 (depends on 13) The device of claim 13 wherein said hinge points are substantially rectangular. ### Claim 15 (depends on 13) The device of claim 13 wherein said nozzle further includes a flexible region. ### Claim 16 (depends on 15) The device of claim 15 wherein said flexible region is formed of a plurality of bellows. ### Claim 17 (depends on 16) The device of claim 16 wherein said bellows are positioned on the lower half of said nozzle. ### Claim 18 (depends on 16) The device of claim 16 wherein said bellows are collapsible bellows.
