FIG. 1shows a blank for a container that is octagonal in cross-section. InFIG. 1the blank20is divided by longitudinal parallel attachment lines22,24,26and28into a cover panel30, a side panel32, a bottom panel34, a side panel36and a cover panel38. The bottom panel34is octagonal in cross section with sides formed by attachment lines24and26, ends formed by transverse parallel attachment lines40and42and beveled corners44,46,48and50extending between the attachment lines24,40,26and42. The width of each of these corners between the attachment lines is the same.

End panels52and54are attached to bottom panel34along the transverse parallel attachment lines40and42. End panel52has an outer edge56and side edges58and60. End panel54has an outer edge62and side edges64and66. The height of each of the end panels52and54is the distance between its attachment line40or42and its outer edge56or62. The width of each of the end panels52or54is the distance between its side edges58and60or64and66.

Each of the cover panels30and38is shaped to form a cover that has the same shape as the bottom panel in the formed container. Cover panel30has a pair of beveled corners68and70and cover panel38has a pair of beveled corners72and74. The width of each of these corners is the same as the width of the corners in the bottom panel.

The end walls in the formed container are formed by the end panels52and54and by end members attached to the side panels. Each of these end members has the same design so the same reference numerals will be used for each of them. End members76aand76bare attached to the sides of side panel32. End members76cand76dare attached to the sides of side panel36. Each of the end members76is attached to the side panel by a transverse attachment line78. Each of the end members76is divided by transverse attachment lines80,82,84and86into corner panel88, end panel90, column panel92, column panel94and attachment panel96. The width of each of the corner panels88between attachment lines78and80is the same as the width of one of the corners44,46,48and50. The combined width of two of the end panels90between attachment lines80and82is the same or less than the width of one of the end panels52and54.

The columns are formed on the inside face of the end panels90. The columns are formed by folding attachment panel96outwardly around attachment line86, folding column panel94inwardly around attachment line84and folding column panel92inwardly around attachment line82. The attachment panel96is fastened to end panel90by glue or staples. This forms the column98.

The container is formed by folding the side panels32and35upwardly around attachment lines24and26until the side panels are perpendicular to the bottom panel34. The end members76are folded inwardly around attachment lines78and the end panels90are folded inwardly around attachment lines80. The corner panels are aligned with their respective corners and the end panels90are aligned with their respective ends. The panels92of adjoining columns98butt together and can be glued together. The end panels52and54are folded upwardly around attachment lines40and42. Each of the end panels52and54is fastened to a pair of end panels90by glue or staples. The formed container is shown inFIGS. 6 and 7.

Each of the cover panels130and138is shaped to form a cover that has the same shape as the bottom panel in the formed container.

The end walls in the formed container are formed by the end panels152and154and by end members attached to the side panels. Each of these end members has the same design so the same reference numerals will be used for each of them. End members176aand176bare attached to the sides of side panel132. End members176cand176dare attached to the sides of side panel136. Each of the end members176is attached to the side panel by a transverse attachment line178. The transverse attachment lines on each side of the side panel are parallel. Each of the end members176is divided by parallel transverse attachment lines180,182and184into end panel190, column panel192, column panel194and attachment panel196. The combined width of two of the end panels190between attachment lines178and180is the same or less than the width of one of the end panels152and154.

The columns are formed on the inside face of the end panels190. The columns are formed by folding attachment panel196outwardly around attachment line184, folding column panel194inwardly around attachment line182and folding column panel192inwardly around attachment line180. The attachment panel196is fastened to end panel190by glue or staples. This forms the column198.

The container is formed by folding the side panels132and135upwardly around attachment lines124and126until the side panels are perpendicular to the bottom panel134. The end panels190are folded inwardly around attachment lines178and are aligned with their respective ends. The panels192of adjoining columns198butt together and can be glued together. The end panels152and154are folded upwardly around attachment lines140and142. Each of the end panels152and154is fastened to a pair of end panels190by glue or staples. The formed container is shown inFIG. 9.

The following embodiments have only one column at each end of the container.

The columns are formed by folding attachment panel396outwardly around attachment line384, folding column panel394inwardly around attachment line382and folding column panel392inwardly around attachment line380. The attachment panel396is fastened to end panel390by glue or staples. This forms the column398.

End members400aand400bare attached to the sides of side panel336. The end members400aand400bare the same and like reference numerals will be used for them. The end members400aand400bare attached to side panel336by transverse attachment lines402. The width of end panel400is the distance between attachment line402and the outer edge404opposite the attachment line402of the end panel400. The combined width of an end panel390and an end panel400is the same or less than the width of an end panel352or354.

The container is formed by folding end panels390inwardly around attachment lines378. The side panel232is folded upwardly around attachment line224until the end members276rest on the bottom panel234. The side panel236is folded upwardly around attachment line226until it is perpendicular to the bottom panel234. The end panels308are folded inwardly around attachment lines304and the end members300are folded inwardly around attachment lines302. The corner panels are aligned with their respective corners and the end panels290and308are aligned with their respective ends and abut. The columns298are on the inside of the container. The end panels252and254are folded upwardly around attachment lines240and242. Each of the end panels252and254is fastened to its associated end panels290and308by glue or staples. The widths of the end panels90and the heights of the panels52and54will determine whether the end panels290and308on each end of the container will be near each other or abut. The container is shown inFIG. 18.

In these last two embodiments, the end members having the corner panels need not be attached to the same side panel.

All of the transverse attachment lines are parallel.

The container may be made of corrugated board, container board or fiber board.
