Abstract
This specification describes an improved method for making a container that has a square bag construction at its lower end and an upper end constructed as a folding box. The method produces such a container with a flexible handle that is permanently attached to the container in contrast with the prior art where economical construction requires that the user attach a separate handle to the container. With this invention, changes in the reinforcing of the upper panels of the container and a novel sequence in the manufacturing steps make the provision of a permanently attached handle both economical and practical. The product has novel features of construction that make it possible to manufacture the product on automatic machines which make conventional shopping bags and with limited alterations in the standard shopping bag machines.
