Abstract

A container including a paper-based cradle, a paper-based insert, and a thermoplastic film. The cradle has exterior corner panels that form a transition between the exterior end panels and exterior side panels. The cradle and insert are held together by the thermoplastic film that is thermoformed into conformance with the cradle and insert. The exterior corner panels at the junctures between the exterior end panels and exterior side panel can reduce the potential for defects in the thermoformed thermoplastic film.

First claim

What is claimed is:

1 . A container comprising:
a paper-based cradle comprising: a bottom panel; a pair of opposing exterior end panels, wherein each exterior end panel is foldably connected to said bottom panel and directed towards a top of said container; a pair of opposing exterior side panels, wherein each exterior side panel is foldably connected to said bottom panel and directed towards said top; and four exterior corner panels, wherein each exterior corner panel is foldably connected to said bottom panel at an exterior corner panel proximal end and extends to an exterior corner panel distal end and is directed towards said top, wherein each exterior corner panel comprises opposing exterior corner panel lateral edges extending from said exterior corner panel proximal end to said exterior corner panel distal end, wherein individually each exterior corner panel lateral edge has a corner panel wing foldably connected thereto; wherein individually each exterior corner panel is positioned to form a juncture between one exterior end panel and one exterior side panel; wherein for each exterior corner panel one corner panel wing is in at least partial facing relationship with one exterior end panel and one corner panel wing is in at least partial facing relationship with one exterior side panel; a paper-based insert partially inboard of said cradle and comprising: a continuous brim; a pair of interior end panels foldably connected to said brim, wherein each interior end panel is directed towards a bottom of said container and is in at least partial facing relationship with one exterior end panel; and a pair of interior side panels foldably connected to said brim, wherein each interior side panel is directed towards said bottom and is in at least partial facing relationship with one exterior side panel; and a thermoplastic film inboard of said insert and joined to said brim, said bottom panel, said interior end panels, said interior side panels, said exterior end panels, said exterior side panels, and said exterior corner panels; wherein individually each corner panel wing in at least partial facing relationship with one exterior end panel has a first wing aperture therethrough; and wherein said thermoplastic film is joined to said exterior end panels through said first wing apertures.

2 . The container according to claim 1 :
wherein individually each corner panel wing in at least partial facing relationship with one exterior side panel has a second wing aperture therethrough; and wherein said thermoplastic film is joined to said exterior side panels through said second wing apertures.

3 . The container according to claim 1 :
wherein individually each said interior side panel has one or more interior side panel apertures therethrough; and wherein said thermoplastic film is joined to said exterior side panels through said interior side panel apertures.

4 . The container according to claim 3 , wherein individually each said interior side panel has an interior side panel area not inclusive of said interior side panel apertures and said interior side panel apertures have a side panel aperture open area that is more than 20% of said interior side panel area.

5 . The container according to claim 1 :
wherein individually each said corner panel wing having a first wing aperture has a first wing area not inclusive of said first wing aperture and said first wing aperture has a first wing aperture open area that is more than 25% of said first wing area; and wherein said thermoplastic film is joined to said exterior end panels through said first wing apertures.

6 . The container according to claim 1 :
wherein individually each corner panel wing in at least partial facing relationship with one exterior side panel has a second wing aperture therethrough; wherein individually each said corner panel wing having a second wing aperture has a wing area not inclusive of said second wing aperture and said second wing aperture has a second wing aperture open area that is more than 25% of said second wing area; and wherein said thermoplastic film is joined to said exterior side panels through said second wing apertures.

7 . The container according to claim 1 , where said container is devoid of adhesive between parts of said cradle that are in facing relationship with one another and is devoid of adhesive between parts of said insert in facing relationship with parts of said cradle.

8 . The container according to claim 1 , wherein said cradle and said insert are held together exclusively by said thermoplastic film.

9 . The container according to claim 1 , wherein said cradle, said insert, and said thermoplastic film have a combined weight, wherein cellulose fibers constitute more than 80% of said combined weight.

10 . The container according to claim 1 :
wherein said thermoplastic film has interior surface along said bottom panel oriented towards said top; wherein said thermoplastic film along said brim has top surface oriented away from said bottom panel; wherein said top surface bounds an open end; wherein said open end has a maximum open dimension; and wherein said container has a depth measured orthogonally away from said interior surface to said open end that is from 20 mm to 150 mm.

11 . A container comprising:
a paper-based cradle comprising: a bottom panel; a pair of opposing exterior end panels, wherein each exterior end panel is foldably connected to said bottom panel and directed towards a top of said container; a pair of opposing exterior side panels, wherein each exterior side panel is foldably connected to said bottom panel and directed towards said top; and four exterior corner panels, wherein each exterior corner panel is foldably connected to said bottom panel at an exterior corner panel proximal end and extends to an exterior corner panel distal end and is directed towards said top, wherein each exterior corner panel comprises opposing exterior corner panel lateral edges extending from said exterior corner panel proximal end to said exterior corner panel distal end, wherein individually each exterior corner panel lateral edge has a corner panel wing foldably connected thereto; wherein individually each exterior corner panel is positioned to form a juncture between one exterior end panel and one exterior side panel; wherein for each exterior corner panel one corner panel wing is in at least partial facing relationship with one exterior end panel and one corner panel wing is in at least partial facing relationship with one exterior side panel; a paper-based insert partially inboard of said cradle and comprising: a continuous brim; a pair of interior end panels foldably connected to said brim, wherein each interior end panel is directed towards a bottom of said container and is in at least partial facing relationship with one exterior end panel; and a pair of interior side panels foldably connected to said brim, wherein each interior side panel is directed towards said bottom and is in at least partial facing relationship with one exterior side panel; and a thermoplastic film inboard of said insert and joined to said brim, said bottom panel, said interior end panels, said interior side panels, said exterior end panels, said exterior side panels, and said exterior corner panels; wherein individually each corner panel wing in at least partial facing relationship with one exterior side panel has a second wing aperture therethrough; and wherein said thermoplastic film is joined to said exterior side panels through said second wing apertures.

12 . The container according to claim 11 :
wherein individually each s
