Abstract
Abstract Individual irregular tetrahedral units are formed from packaging material supplied in roll form and drawn around a hollow filling mandrel to form an elongate, continuous tube which is then sealed by sealing jaws operating at spaced increments axially of the tube. Each sealing operation forms the top seal of one tetrahedral unit and the bottom seal of another, and the tubular material is subsequently cut along approximately the median line of each seam. The sealing jaws are also positioned so as to intersect the axis of the tube at pre-determined oblique angles to thus form individual tetrahedral units each face of which is a right triangle and which thus can be compactly nested without voids within a conventional triangular or rectangular carton.

Claim 5
Dependent Claim
29 words
The invention according to claim 1 wherein said containers are bound to one another by an adhesive at their respective interfaces to maintain the containers in the assembled package.
Claim 6
Dependent Claim
64 words
A package comprised of four product-enclosing containers, said package having a rectangular three-dimensional outline, each of said containers being generally of an irregular tetrahedral shape, each face of each container being iN the general configuration of a right triangle, said containers being oriented within said package with the long edge of the container extending through said package and between two diagonally opposed corners thereof.
Claim 7
Dependent Claim
64 words
A package comprised of four product-enclosing containers, said package having a rectangular three-dimensional outline, each of said containers being generally of an irregular tetrahedral shape, each face of each container being iN the general configuration of a right triangle, said containers being oriented within said package with the long edge of the container extending through said package and between two diagonally opposed corners thereof.
Claim 8
Dependent Claim
44 words
