Abstract
A cylinder type display box is made from a single sheet of paperboard material and includes a base and two upstanding sidewalls. The display box further includes a tubular plastic sleeve member disposed over the base and sidewalls so as to form a plastic front wall, top wall, and back wall. The base and sidewalls of the box are generally prismatic in configuration, each having spaced apart panel members. The base includes a pair of substantially parallel locking slits extending from the front wall to the back wall, each of the locking slits being adjacent to one of the sidewalls. Each locking slit includes an elongated central portion and a pair of end portions, the end portions of each slit being flared toward its adjacent sidewall. Each of the sidewalls has a locking portion receivable in the locking slit adjacent thereto. Each locking portion includes a central portion integral with the respective sidewall and a pair of end tabs. The central locking portion of each sidewall is received in the elongated portion of its respective locking slit. The end tabs of each sidewall are received in the flared end portions of its respective locking slit thus, locking the sidewalls into the base portion.
