Description

FIG. 1 is a front view of a sagger showing my new design;

FIG. 2 is a rear view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a bottom view thereof in which the outer periphery of the bottom surface is stepped up along its entire edge, thereby forming a recess (see reference cross-sectional view of FIG. 8 taken in the direction of line A-A);

FIG. 5 is a left side view thereof;

FIG. 6 is a right side view thereof;

FIG. 7 is a perspective view thereof in which the fine lines depicted on the inner surface of the sagger represent ridgelines that define the three-dimensional shape of the surface;

FIG. 8 is a sectional view taken along lines A-A of FIG. 3; and,

FIG. 9 is a perspective view thereof showing usage conditions of several in which the fine lines depicted on the inner surface of the sagger represent ridgelines that define the three-dimensional shape of the surface.

The broken lines in the FIG. 9 are for the purpose of illustrating the state of use when the saggers are stacked vertically and form no part of the claimed design.

As shown in the reference perspective view indicating the state of use, when the saggers are stacked vertically, the upper ends of the corner portions engage with the recesses (depressions) on the bottom surface of the adjacent sagger above. This configuration helps suppress horizontal displacement between the stacked saggers. Additionally, notches are formed on each side surface of the sagger to provide ventilation spaces when the saggers are stacked.

Claims

The ornamental design for a sagger as shown and described.
