Abstract
Abstract A two-piece knockdown table formed of a corrugated paperboard base and a table top member supported thereon. The two pieces which form the table are adapted to be shipped in flat condition and to be erected at the point of use into a table which has substantial stability and strength. The table top member is formed with a depending flange which is adapted to engage the panels of the base member. The base member has tabs which engage slots formed in the depending flange member of the table top member to secure the base member to the top member.

Independent Claim
66 words
A table comprising a base member formed of a blank of corrugated cardboard folded into a plurality of panels to assume a generally polygonal formation in transverse cross-section and a top member supported on the upper edges of said base member, said top member having a flange member depending from the underside thereof, said flange member being engageable with the upper portion of said base member.
Claim 2
Dependent Claim
66 words
A table comprising a base member formed of a blank of corrugated cardboard folded into a plurality of panels to assume a generally polygonal formation in transverse cross-section and a top member supported on the upper edges of said base member, said top member having a flange member depending from the underside thereof, said flange member being engageable with the upper portion of said base member.
Claim 3
Dependent Claim
60 words
The table of claim 1 including means for securing said base member to said top member comprising a plurality of slots formed in said flange member and tab members extending generally upwardly from the upper portion of a plurality of said panels of said base member, each tab member engaGeable with one of said slots formed in said flange member.
Claim 4
Dependent Claim
73 words
The table of claim 1 wherein said flange member has side portions equal in number to the number of panels in said base member so that the said flange member has a formation corresponding to the polygonal formation of the folded base member in transverse section and is substantially coextensive therewith, each of said side portions of said flange member being substantially completely engageable with the upper portion of one of said panels.
Claim 5
Dependent Claim
60 words
The table of claim 3 wherein each of said side portions of said flange member has a slot formed therein, and said base member has tab members extending generally upwardly from the upper portion of a plurality of said panels thereof, each of said tab members being engageable with the slot formed in a side portion of said flange member.
Claim 6
Dependent Claim
53 words
