A novel ice cream product container with complementary closure member is disclosed. The container body member is usually of paperboard and formed from an integral blank comprising edge-reinforcing flaps articulated to wall members, which reinforcing flaps are then folded down upon and secured to their respective wall members to provide a reinforced portion of double thickness in the container formed from the blank. This folded-over, reinforced portion is also present in the flat-folded tube produced from the blank, the squared-up tube, the erected container, and finally in the closed and filled package. This folded-over, reinforced portion of double thickness contains defined areas of low resistance adapted to receive lugs formed in a wall of the complementary closure member. The closure member also provides a complementary channel between essentially upstanding and downstanding walls for receiving the reinforced portion of the container walls in frictional engagement therewith. The defined areas of low resistance in the upper edge areas of the container walls may be provided by cuts or cut-outs, preferably of a generally inverted-V shape, and the corresponding lugs formed in the complementary closure member are complementarily shaped to provide excellent releasable securement of the closure member to the container walls. The combination of the container and complementary closure member, method of closing the container with the complementary closure member, and method of packaging ice cream product therein are also disclosed and form a part of the invention.
A method of closing an open end of a tube or tubular continer, having upstanding walls, the end edges of which walls are folded-over and adhered to said walls to form a folded-over, reinforced portion of double thickness at that end of the tube or tubular container, the inner exposed surface of said folded-over, edge-reinforced portions of the upstanding walls having areas of low resistance defined therein for facilitating the removable securement of a closure member thereto, comprising the steps of placing a container closure member, comprising an upstanding tubular inner wall conforming to the inner surfaces of the walls of the tube or tubular container to be closed by said closure member, and
A method of closing an open end of a tube, having upstanding walls, the end edges of which walls are folded-over and adhered to said walls to form a folded-over, reinforced portion of double thickness at that end of the tube, the inner exposed surface of said folded-over, edge-reinforced portions of the upstanding walls having areas of low resistance defined therein for facilitating the removable securement of a closure member thereto, comprising the steps of placing a container closure member,
A method of closing an open end of a tubular container, having a bottom and upstanding walls, the end edges of which walls are folded-over and adhered to said walls to form a folded-over, reinforced portion of double thickness at that end of the tubular container, the inner exposed surface of said folded-over, edge-reinforced portions of the upstanding walls of said container having areas of low resistance defined therein for facilitating the removable securement of a container closure member thereto, comprising the steps of placing a container closure member,
