Abstract

See full text

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.
