ABSTRACT:
A disposable container consisting of a tetrahedral-shaped chamber and a base member formed from a folded cardboard blank pre-coated with an adhesive layer and having folding guides at desired locations to provide the base with arms to hold the chamber. The chamber is formed from a segment of flexible plastic tubing, sealed at the bottom and sealed at the top on a line transverse to the sealing line at the bottom to form the tetrahedral-shaped chamber. The chamber is stably mounted on the base member, which provides a wide surface for supporting and protecting the tetrahedral chamber and also provides labeling surfaces for the container.
Also set forth is a method for manufacturing and filling containers by folding a blank pre-coated with adhesive along pre-set folding guides to form a base member, attaching the base member to a tubing segment, sealing the tubing segment at one end, filling the tubing segment, and then sealing the other end of the tubing segment on a line transverse to the first sealing line, to form a tetrahedral-shaped chamber for the container.
