Abstract
A wood reinforced corrugated paperboard shipping container is disclosed having a rigid wood base, a wood reinforced corrugated paperboard body attached thereto and a top frame. The wood reinforced corrugated paperboard body includes attaching strips at the location of the base whereby a wood-to-wood connection is achieved. The wood-to-wood connection, in combination with selectively notched vertical reinforcements, provides for heavy equipment to be packed, shipped, handled and stored without container component separation.
Claims18
A wood reinforced corrugated paperboard shipping container comprising:
- a base frame suitable for supporting an article to be packed, said base frame including at least one wood strip that extends substantially a length of said base frame;
- a corrugated paperboard body defining inner wall surfaces and corresponding outer wall surfaces said corrugated paperboard body comprising a wall forming blank of paperboard scored to provide a series of main panels foldably joined together at a plurality of corners and dimensioned for mating engagement with said base frame such that at least one of said main panels extends the length of said at least one wood strip;
- at least one substantially vertically aligned reinforcement fixedly secured to one of said inner wall surfaces of said main panels and positioned adjacent one of said corners thereof, but sufficiently distanced from said corners to permit collapsing of said corrugated paperboard body;
- at least one substantially horizontal attaching strip fixedly secured to one of said inner wall surfaces of said corrugated paperboard body, said at least one attaching strip being positioned on said respective inner wall surface for alignment with said at least one wood strip of said base frame;
- a top frame dimensioned for receipt by said corrugated paperboard body;
- and
- means for attaching said at least one attaching strip to said at least one wood strip
- whereby attachment of said corrugated paperboard body to said base frame provides a wood-to-wood connection that ensures against component separation.

A wood reinforced corrugated paperboard shipping container, comprising:
- a corrugated paperboard body comprising a wall forming blank of paperboard scored to provide a first, a second, a third, and a fourth main panel defining interior container walls and exterior container walls, foldably joined together at corners, said panels each defining an upper portion and a lower portion;
- a pair of vertical supports fixedly secured to the interior wall of said first main panel and said third main panel of said corrugated paperboard body, each of said pair of vertical supports having a beveled top portion and a notched lower portion, said notched portion being one-half the width of the remaining portion of said vertical support;
- a plurality of wooden attaching strips secured about a lower portion of said corrugated paperboard body such that at least one of said attaching strips is secured to one of each of said first, said second, said third and said fourth main panels in substantial alignment with said notched lower portion of said vertical supports, said attaching strips being of a width substantially equal to that of said vertical supports at said notched portions;
- a wooden rigid base member for mating connection with said corrugated paperboard body such that said base member is aligned with said attaching strips;
- a top frame, said top frame including beveled notches positioned for mating engagement with said top beveled portions of said vertical supports;
- and
- means for attaching said wooden attaching strips to said rigid base member, whereby attachment of said attaching strips of said corrugated paperboard body to said base member provides a wood-to-wood connection ensuring against separation thereof.

A wood reinforced corrugated paperboard shipping container, comprising:
- a base frame for supporting an article to be packed, said base frame including at least two [cornered] wood strips that extend substantially the length of said base frame ;
- a wood reinforced corrugated paperboard body defining inner container walls and corresponding outer container walls, said paperboard body comprising a wall forming blank of paperboard scored to provide a series of panels foldably joined together at a plurality of corners and configured for engagement to said base frame;
- a plurality of substantially vertical, wooden supports fixedly secured to said inner container walls adjacent said corners and sufficiently distanced therefrom to permit collapse of said paperboard body, said substantially vertical supports each including a notched lower portion;
- at least two attaching strips fixedly secured to a lowermost portion of said inner container walls said two attaching strips being substantially equal in length to said wood strips of said base frame;
- and
- means for securing said attaching strips to said wood strips,
- whereby said wood reinforced corrugated paperboard body is secured to said base frame such that said wood strips of said base frame extend into said notches of said vertical supports, whereby any lifting force exerted on said base frame is in part transferred to said vertical supports and any clamping force exerted on said vertical supports is, in part, transferred to said wood strips.

A reinforced corrugated paperboard shipping container, comprising:
- a base frame for supporting an article to be packed, said base frame including at least two wood strips;
- a corrugated paperboard body comprising a wall forming blank of paperboard scored to provide a series of panels foldably joined together at a plurality of corners and configured for engagement to said base frame;
- a plurality of substantially vertical supports fixedly secured to said container walls adjacent said corners for reinforcing said paperboard body and sufficiently distanced therefrom to permit collapse of said paperboard body;
- at least two attaching strips, each one fixedly secured to a separate one of said panels and positioned for alignment with one of said wood strips;
- and
- means for connecting said attaching strips to said wood strips,
- whereby engagement of said reinforced corrugated paperboard body to said base frame by connecting said attaching strips to said wood strips ensures against component separation.
