Flame Shield for Cigarette Lighter and Cigarette Lighter Including Said Flame Shield

(i) Field of the Invention

This invention relates to cigarette lighters and more particularly to improvements in such lighters which include a device to be used as a shield for the flame to enable the lighter to be lit even in a strong wind.

(ii) Description of the Prior Art

There are many instances where it is difficult to light such a cigarette lighter because of wind conditions. A problem which previous proposed solutions have not adequately addressed is that of effectively shielding the flame from the wind while allowing easy access of the cigarette to the so-shielded flame.

Many solutions have been proposed but none are completely satisfactory. Thus Canadian Pat. No. 286,802 issued Jan. 29, 1929 to M. Perrera provided a simple cylindrical sheath movably and adjustably received within an annular chamber of the lighter.

Canadian Pat. No. 287,265 issued Feb. 19, 1929 to E. F. Clark provided wind break having side walls and an end wall enclosing the flame elements on three sides and a wind break wall pivotted on the end wall to shield the open top of the enclosure.

Canadian Pat. No. 311,040 issued May 5, 1931 to L. V. Aronson provided a U-shaped windshield member upstanding from the top of the lighter with an arm extending along the walls to shield the wick therebetween. A side portion of the shield was cut away to permit access of a cigarette from the side of the lighter when the lighter was held in a horizontal position.

Canadian Pat. No. 354,896 issued Dec. 24, 1935 to H. S. Silberknopf provided a wind-breaking guard sleeve slidable to open and close the wick cap, with a spring to bias the wind-breaking guard sleeve to close the lighter automatically.

Canadian Pat. No. 491,907 issued Apr. 7, 1953 to W. I. Nissen provided a windshield surrounding the burner opening which was slidable, in a passageway, between a burner-opening exposing position and a burner-opening shielding position, and resilient means to urge the face of the windshield into contact with the passageway.

U.S. Pat. No. 1,720,460 issued July 9, 1929 to L. C. Ament provided a windshield having rear wall, side walls and an open top, and hinged arms to embrace the lighter to clamp the shield to the lighter.

(i) Aims of the Invention

In spite of these prior old patents, there is still a need for the provision of a windshield for a cigarette lighter which will allow ready access of the cigarette to the flame while effectively shielding the flame.

Another object of this invention is to provide such a cigarette lighter in the form of a disposable lighter, with a windshield that may be either permanently, but slidably, mounted with respect thereto or removably mounted with respect thereto.

(ii) Statements of Invention

By this invention, an improvement is provided in a disposable lighter having a fuel receptacle, a pyrophoric sparking wheel lighting mechanism mounted on the top edge thereof, and a finger-actuated fuel-control valve adjacent the sparking wheel, the improvement comprising a windshield of similar cross-section to that of the receptacle and slidably retained on the receptacle, the windshield comprising two solid side walls, a solid back wall, an open top and an open wall having a lower peripheral ring joining two mutually opposed solid side walls, the solid side walls having a cut-away portion to allow unhindered access by a thumb of a user to the sparking wheel lighting mechanism having a cigarette-access opening above the cut-away portion of the side walls, the windshield being slidable along the outside of the receptacle from a lower position where the bottom periphery of the windshield abuts a lower cap on the receptacle to an upper position where the upper edge of the lower receptacle ring abuts, the windshield being between about 50% and about 100%, and preferably about 100% of the height of the receptacle.

This invention also provides for a windshield for a conventional disposable lighter having a fuel receptacle, a pyrophoric sparking wheel lighting mechanism mounted on the top edge thereof, and a finger-actuated fuel-control valve adjacent the sparking wheel, the windshield being of similar cross-section to that of the receptacle of the lighter with which it is adapted to be used and being adapted to be slidably retained on the receptacle, the windshield comprising two solid side walls, a solid back wall, an open top and an open front wall having a lower peripheral ring joining two mutually opposed solid side walls, the side walls having a cut-away portion to allow unhindered acess by a thumb of a user to the sparking wheel lighting mechanism having a cigarette-access opening adapted to be situated above the cut-away portion of the side walls, the windshield being slidable along the outside of the receptacle from a lower position where the bottom periphery of the windshield abuts a lower cap on the receptacle to an upper position where the upper edge of the lower peripheral ring abuts an upper stop member on the receptacle, the windshield being between about 50% and about 100%, and preferably about 100% of the height of the receptacle of the disposable lighter it is adapted to be used with.

(iii) Other Features of the Invention

By one feature thereof, the open front wall is provided with a pair of inwardly directed partial front walls, so that the opening in the open front wall is narrower than the width of the receptacle

By another feature of the invention, the open front wall is provided with an upper, rigidifying ring.

By yet a further feature thereof, the windshield is made of anodized aluminum.
