The ornamental design for a strip of barrierenvelopes, as shown and described.
FIG. 1 is a front and top perspective view of a strip of barrier envelopes, showing our new design, wherein the envelopes are open along the top edge thereof;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a top view thereof;
FIG. 5 is a bottom view thereof; and,
FIG. 6 is an enlarged view of Section VI of FIG. 1, showing the front surface cut away from one envelope for ease of illustration, to show an adhesive strip along the interior section of the open top end, which is visible during use of the envelopes.
The strip of barrier envelopes is shown with a symbolic break in its length. The appearance of any portion of the article outside of the dash-dot lines along both ends of the strip form no part of the claimed design. The dash-dot lines of section VI in FIG. 1 indicate the enlarged view of FIG. 6 and are not part of the claimed design. The broken lines between the individual envelopes indicate perforations that form part of the claimed design.
