Abstract: A mounting collar for a vacuum cleaner bag comprising three or more panels defined from a unitary blank and adhesively bonded in overlying relation to each other. The panels incorporate central aligned openings therethrough which, either in and of themselves or with an adhesively secured elastomeric sheet, provide for a sealing to the exhaust tube of a vacuum cleaner. The blank and the individual panels formed therefrom are from a low caliper stock paperboard material within the range of 15-30 points (0.015 inch to 0.030 inch). The intermediate panel or panels of the overlying panels are peripherally smaller than the outer panels and have the openings therein peripherally larger than the aligned openings in the outer panel.

Abstract: A folded-blank carton including opposed first and second face walls, opposed first and second side walls, and opposed first and second end walls. At least the first end wall is defined by inner and outer overlying panels, the inner panel being integral with the second face wall along a juncture forming fold line, and the outer panel being integral with the first face wall along a junction forming fold line. The outer panel includes an edge generally aligned over the second face wall and an outwardly projecting tab integral with the outer panel along this edge. A tearout section is defined transversely across the outer panel in alignment with the tab, and a partially severable access section is hinged to the first face wall in alignment with the tearout section for an outward swinging of the tab, tearout section and access section to expose the contents of the carton.
