ABSTRACT:
A compact, low shipping volume paper product comprising a compression loaded, core-wound roll of paper and a compression constraining element; and concomitant method of making such a paper product. The roll comprises a length of paper which is wound on a tubular core, and which roll may have an obround or parallelopipedal shape due to being unidirectionally compressively loaded after winding; and then constrained against expanding by a suitable constraining element. Preferably, the roll is sufficiently compressively loaded to completely flatten the core. In another aspect of the invention, the roll may be further compressed by applying a compressive loading that is substantially greater than that needed to cause the core to become flat; and, some of that high compressive loading may be relieved before the constraining element is applied or secured. The paper product is susceptible to being reshaped by a consumer upon removal of the constraining element so that both the product and the core become somewhat round in cross section. Such a product may, for example, be a contemporary roll of toilet tissue or disposable paper towels on a contemporary paperboard core. The paper product may comprise a plurality of such rolls, and may be constrained by enclosures such as polyethylene film, and/or bands about individual rolls, and/or a band about an array of rolls.
