Abstract: A blank forming step for forming a sheet-shaped resin blank able to be formed into a box by folding and bending, and a score line forming step of forming score lines in score line forming areas of the blank which are to be bent to form outer edges of the box, to extend in the direction in which the outer edges should extend. In the score line forming step, the score lines are formed in a manner causing grooves to be produced on the back side of each score line forming area, along the score lines, through plastic deformation. The blank therefore does not undergo tensile stress pulling on the blank to either side of each groove, and thus, does not undergo warping as a whole. The blank thus retains its sheet shape and can be steadily supplied to a packaging machine.

The flexible wall (8) is preferably deformed into a configuration which enables it to lie, unstressed, against the internal surface of the housing part (2), so that herbicide contained in the cavity between the housing part (2) and the flexible wall (8) can flow substantially completely from the container under gravity.

Abstract: A method of folding into packages, in connection with the manufacture thereof, disposable absorbent articles such as diapers or incontinence protectors comprising an absorbent body (1) enclosed in a casing extending laterally beyond the absorbent body and having casing portions intended to seal around the abdomen of the wearer, as well as elastic leg bands or threads (6, 7) affixed to the casing with portions (6', 7') extending at least partially along either side edge of the article at a distance beyond the absorbent body.

Abstract: A method of forming a container from a flat, substantially homogeneous blank of fibrous substrate, comprising the steps of shaping the blank into a formed container having a bottom wall, an up-turned side wall extending from the bottom wall, a rim outwardly extending from the side wall and a lip downwardly curving from the rim and including a plurality of radially-extending, circumferentially-spaced pleats formed in the side wall, rim, and lip, each pleat including at least three layers of the blank; and applying sufficient heat and pressure to the side wall and rim to decrease the thickness thereof to less than that of the blank and to transform each pleat into a substantially integrated fibrous structure in which the constituent layers generally lack individual identity, each structure having a density greater than and a thickness substantially equal to adjacent areas of the side wall and rim.

Abstract: A pressed paperboard container (10) is formed having a bottom wall (11), an upturned side wall (12), and an overturned rim (13 ) extending from the side wall which is denser and thinner than the rest of the container. The container is formed by pressing a flat circular blank (27) between upper and lower dies (25, 26) having die surfaces (31, 32, 38, 39, 40) which shape the blank into proper form, and the surfaces of the dies (25, 26) at the rim area (13) of the container are shaped to exert extremely high compressive stresses on the rim, particularly at the folded areas (20) formed in the rim during initial shaping of the container. The high compressive stresses applied to the rim area, along with proper moisture levels maintained in the paperboard and the heating of the paperboard by the heated dies, causes the paperboard in the rim area to deform plastically, densify, and fill in voids created as the blank was pressed into the container form.

Abstract: A self-raising post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a lamp post, or for other comparable uses in road traffic environments, has a channel-shaped bending zone with substantially arcuate cross-section and with the convex side facing the on-coming traffic. The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.
