We claim the ornamental design for a cooling jacket for blenders, as shown and described.
FIG. 1 is a front view of a cooling jacket for blenders of the present invention;
FIG. 2 is a top view thereof;
FIG. 3 is a bottom view thereof;
FIG. 4 is a first side view thereof;
FIG. 5 is a second side view thereof;
FIG. 6 is a rear view thereof;
FIG. 7 is a cross-sectional view taken along the line 7-7 of FIG. 1;
FIG. 8 is an enlarged cross-sectional view of the area denoted by the line 8-8 of FIG. 7; and,
FIG. 9 is a front perspective view thereof shown in an environmental use.
The broken lines shown represent unclaimed subject matter and form no part of the claimed design. The stippled shading shown in the front and rear views of the claimed design represents touch fastener fabric strips. The cross-sectional views shown in FIG. 7 and FIG. 8 exhibit coolant filling in the jacket. Further, the oblique line shading shown in FIGS. 1, 6 and 9 shows transparent surfaces. In FIGS. 1, 6 and 9, the transparent shading is rendered with straight lines for simplicity and does not represent the shapes of the transparent surfaces.
