Cylindrical display container formed from a flat blank

Claim 1

A display container consisting of a cylindrical body and a pair of end caps, said cylindrical body being formed from a knock-down, flat-folded blank having a paperboard body panel and a pair of attachment flaps hingedly connected to its opposite side edges, and a transparent body panel in opposing relation to said first named body panel with its opposite side edges secured to said attachment flaps, said transparent body panel being formed from a self-sustaining flexible sheet of plastic material, said first named paperboard body panel having a width equal to one-half the perimeter of the container body when erected into essentially cylindrical form, with the remaining one-half of the container body defined by said transparent body panel and said attachment flaps, said attachment flaps acting to hingedly connect the opposite side edges of said transparent panel to said paperboard body panel, whereby the flat-folded blank may be erected to cylindrical configuration by flexing the body panels outwardly relative to each other, whereupon the end caps may be inserted into the opposite ends of the cylindrical body to maintain it in erected condition and close its opposite ends, said end caps having annular body portions of a size to be snuggly received in the ends of the container body when in essentially cylindrical form, at least one annular ridge on the body portion of each of said end caps, and ridge defining score lines in said paperboard body panel extending parallel to and adjacent the opposite end edges thereof, said score lines being positioned to enter into operative engagement with the annular ridges on the body portions of said end caps, whereby to tightly secure the end caps to said container.
