The ornamental design for a disposable papertoweldishcover, as shown and described.
FIG. 1 is a bottom plan view of a disposable paper towel dish cover, showing my new design;
FIG. 2 is an isometric view thereof; and,
FIG. 3 is a second isometric view showing my design in an alternate position thereof.
The front view of the disposable paper towel dish cover is shown in the perspective view for a clearer specification, with the rear view being a mirror image.
The broken line showing of a dish, dish contents and steam is included for the purpose of illustrating portions of the “article” and forms no part of the claimed design.
