Gas Cylinder

FIG. 1 is a perspective view of a gas cylinder showing our new design;

FIG. 2 is a front view thereof;

FIG. 3 is a rear view thereof;

FIG. 4 is a left side view thereof;

FIG. 5 is an enlarged perspective view thereof along the circle 5 in FIG. 1 ;

FIG. 6 is an enlarged cross-sectional side view thereof along the line 6 - 6 in FIG. 2 , shown with the rear portion of the gas cylinder removed for clarity of disclosure; and,

FIG. 7 is an enlarged cross-sectional side view of the gas cylinder, shown in an environment of use and with the rear portion of the gas cylinder removed for clarity of disclosure.

The broken lines in the drawings illustrate portions of the gas cylinder that form no part of the claimed design.

The short dash-long dash broken lines surrounding details shown in FIGS. 1 and 5 are for the purpose of annotating the enlarged views only and form no part of the claimed design.

The dash-dot-dash-dot broken lines shown in FIGS. 6 and 7 are boundary lines, which define the bounds of the claimed design. The claimed design extends to the boundary lines but does not include the boundary lines.

The wavy broken lines in FIGS. 6 and 7 are for the purpose of illustrating that the non-claimed rear portion has been removed for clarity of disclosure and from no part of the claimed design.

The additional broken lines shown in FIG. 7 depict environmental subject matter and form no part of the claimed design.

The right side, top, and bottom views of the claimed portion of the gas cylinder are the same as the left side view and therefore not shown.
