Abstract: The exposed edge of a box is covered by placing a strip of heat-shrinkable PVC around the box so that it projects axially beyond the box edge and heating the strip so that the projecting portion shrinks and bends over the box edge, covering it. The projecting portion can be made to project far enough so that, when the strip shrinks and bends, a portion protrudes inwardly beyond the box edge. That protruding portion is then pressed against the inner box wall by a fitted lid or mandrel. A second strip can then be applied in similar fashion and shrunk to form a guarantee seal between the box and lid. An end of the second strip is left free to provide a seal tearing grip.

Abstract: The invention disclosed sets forth a method and machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web. The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats.

Abstract: An apparatus is provided for practicing the method of forming a reduced size textured painting. The painting is prepared on a polystyrene substrate which has been previously heated and stretched substantially equally in two orthogonal directions, i.e., lengthwise and widthwise. After the stretching in the presence of heat, the substrate is cooled to room temperature and retains its stretched configuration. Acrylic or oil paint is then smoothly applied and the combination of paint and substrate is heated once again after the paint has dried. The heating shrinks the substrate back to its original, pre-stretched size, with the paint shrinking at a differential rate. As a result of the differential shrinking, the previously smooth paint assumes a textured surface on the now-shrunk substrate.

A two-piece container can be formed by sealing a bottom disc member to the end of the sidewall, and a one-piece container can be formed by collapsing and fusing the end of the sidewall sleeve to close the bottom of the container.
