Seal pattern for retroreflective trim

Description

The present invention is a new and ornamental design for a seal pattern applied to a strip of retroreflective material, which strip of retroreflective material is referred to herein as retroreflective trim. The seal pattern can be an artifact of localized melting (e.g. by known radio frequency welding, ultrasonic welding, or hot can processes) two components of the retroreflective material together—a retroreflective sheeting and a separate seal film—to form sealed cells that protect minute retroreflective elements on the retroreflective sheeting. The breakaway lines at the end of the depicted retroreflective trim indicate that the length of the trim is not limited, it being understood that the ornamental seal pattern can repeat along such length.

FIG. 1 is a perspective view of a seal pattern for retroreflective trim, showing our new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a side view thereof; and,

FIG. 5 is an end view thereof.

Claims
