US 6,364,201 B1 · Disposable all-purpose container assembly

Abstract

A disposable all-purpose container assembly includes a disposable frustoconical container formed from polymer coated paper and a saddle-like insulation attachment straddling an associated portion of the container sidewall and mounted in fixed position on the sidewall. A raw edge of the sidewall blank is sealed with polymer tape to prevent wicking or migration of liquid from the container into the sidewall. The tape also enhances the bond along the sidewall seam. The insulation attachment has a plurality of spaced apart ribs which engage the outer surface of the sidewall. The ribs, and portions of the outer surface of the sidewall and inner surface of the insulation attachment define air spaces between the container and the insulation attachment. The insulation attachment has a pair of handle sections movable to a holding position for optional use. A ribbed insulation sleeve provided with the handle sections foldable to a holding position to form a handle for optional use on a frustoconical all-purpose container of disposable type is also disclosed. The selective use of polymers having both high and low melting temperatures enables the use of a wide range of polymer coating materials for coating the interior surfaces of the container.

A disposable all-purpose container assembly comprising;

a container formed from polymer coated paper and having a bottom wall and a sidewall having inner and outer surfaces and including an integral annular rim defining an opening at an upper end of said container, said sidewall having a high temperature polymer coating on said inner surface and first and second raw edges at opposite ends thereof, a strip of low temperature polymer sealing tape extending along and sealing said first raw edge and bonded to said high temperature polymer coated inner surface and to said outer surface of said sidewall along marginal portions of said sidewall adjacent said first raw edge, said sidewall having a seam formed by the overlapping face-to-face joinder of marginal portions of the sealed first raw edge and said second raw edge, said sealed first raw edge being disposed within said container, said bottom wall having polymer coated top and bottom surfaces, at least one of said surfaces including said top and bottom surfaces being coated with a low temperature polymer, said high temperature polymer coated inner surface of said sidewall, being bonded to said at least one of said surfaces.

A disposable all-purpose container assembly comprising:

a container formed from polymer coated paper and having an opening at an upper end, said container including a container sidewall formed from a sidewall blank having inner and outer surfaces, said sidewall blank having a high temperature polymer coating on said inner surface and first and second raw edges at opposite ends thereof, a strip of low temperature polymer sealing tape extending along and sealing said first raw edge and bonded to said high temperature polymer coated inner surface and to said outer surface of said sidewall blank along marginal portions of said sidewall blank adjacent said first raw edge, said container sidewall having a seam formed by overlapping face-to-face bonded joinder of taped marginal portions of the sealed first raw edge and said second raw edge, said sealed first raw edge being disposed within said container, said container having a bottom wall and an annular skirt depending from said bottom wall and formed from a bottom wall blank having polymer coated top and bottom surfaces, said annular skirt having a polymer coated outer surface defined by said top surface and a polymer coated inner surface defined by said bottom surface, at least one of said surfaces including said top surface and said bottom surface being coated with a low temperature polymer, said high temperature polymer coated inner surface of said container sidewall being bonded to said at least one of said surfaces including said inner surface and said outer surface.
