Abstract

Abstract A paint strainer has a generally conical body formed of a thin imperforate sheet material such as paper. The body has a plurality of cutouts covered by straining screen means with a filling opening defining a preselected circumference. A plurality of diametrically opposed tabs at 180* locations are integrally formed with the body and extend outwardly from the filling opening. Each of the tabs defines a base line extending over a distance corresponding to at least 17 1/2 percent of the circumference of the filling opening. The tabs can be perforated or scored to allow them to be bent over a support structure or removed entirely. The tabs having a wide base, enhance the load carrying characteristics of the body when hand or mechanically held by the tabs. Buckling, wrinkling and sagging are thus eliminated when the strainer body is filled.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 169 words
A paint strainer comprising, a generally conical one-piece body formed of a thin imperforate paper sheet material formed with an overlying generally straight edge, said body defining two generally sector-shaped cutouts at an apex end thereof and an opposing open end defining a generally circular filling opening having a preselected circumference, perforate strainer screen means extending over said cutouts, a plurality of tabs integrally formed with said body and extending outwardly from said filling opening, said tabs being diametrically opposed and each defining a hole therein with the holes being 180* apart, each said tab defining a broad attachment base line and an outer edge in the form of a generally inverted wide mouth tapering Ushape, each of said base lines extending over a distance corresponding to at least 17 1/2 of the circumference of said filling opening to enhance the load bearing characteristics of the body to cause support for said body over a substantial portion of said circumference when said tabs are used to lift said strainer.
Claim 2
Dependent Claim 169 words
A paint strainer comprising, a generally conical one-piece body formed of a thin imperforate paper sheet material formed with an overlying generally straight edge, said body defining two generally sector-shaped cutouts at an apex end thereof and an opposing open end defining a generally circular filling opening having a preselected circumference, perforate strainer screen means extending over said cutouts, a plurality of tabs integrally formed with said body and extending outwardly from said filling opening, said tabs being diametrically opposed and each defining a hole therein with the holes being 180* apart, each said tab defining a broad attachment base line and an outer edge in the form of a generally inverted wide mouth tapering Ushape, each of said base lines extending over a distance corresponding to at least 17 1/2 of the circumference of said filling opening to enhance the load bearing characteristics of the body to cause support for said body over a substantial portion of said circumference when said tabs are used to lift said strainer.
