Definitions

  • the present invention relates to roll products and, in a preferred embodiment, to compressed and hollow coreless rolls of absorbent paper products such as tissue and toweling, commonly referred to as tissue, in flexible packaging that enables the manufacturer to ship a larger usable area of tissue in a given volume while enabling the end user to store tissue in nooks and crannies that might not be suitable for tissue packaged in conventional configurations.
  • a method of packaging batts of textile fibers including: (a) wrapping the initial batt onto a rigid core to form a cylindrical structure; (b) encasing the structure with a bag of an air impervious material and removing the core; (c) evacuating air from the bag to contract the structure and to increase the initial batt density; and then (d) wrapping the contracted structure with a wrapper of sufficient tensile strength to maintain substantially the contracted state.
  • U.S. Pat. No. 5,480,060 to Blythe shows a system for dispensing wipers which includes a bi-directionally compressed hollow coreless roll of wipers configured for center-feed dispensing.
  • Bath tissue is sometimes produced in hollow coreless roll form, typically with a very small axial central cavity (see U.S. Pat. No. 4,487,378 to Kobayashi) to minimize volume, or with a larger central cavity when the tissue roll is configured for center-feed dispensing. See U.S. Pat. No. 5,849,357 to Andersson.
  • Such products have not been popular with consumers who prefer rolled bath tissue with a relatively large core, outer roll-feed for home use where the product is mounted about a spindle.
  • bath tissue rolls are provided with a core having a diameter of 40 mm or so consisting of a paperboard tube which adds cost, weight and volume to the product. Production efficiency deficits are also associated with tissue having a large core which are often formed on center wind equipment operating at lower winding speeds than surface winders often employed to produce hollow coreless products.
  • U.S. Pat. No. 7,992,818 to Maddaleni relates to a technique for forming rolls of tissue having a large central opening on high speed winders without the expense of a board tube. Rather by providing a discontinuity or low friction interface between adjacent layers in the wound roll, it becomes possible to remove a central plug or small diameter roll of tissue located interiorly to the discontinuity or low friction interface after the roll has been formed.
  • the central plug is a product usable in its own right after removal from the larger roll, particularly where a small, easily carried around supply of tissue is desirable as in a lady's purse for example.
  • a tubular dispensing core with a diameter smaller than the original cavity before collapse is provided which may be inserted into the hollow coreless roll after it is re-formed into cylindrical shape and prior to dispensing.
  • a core can suitably be 2-50% smaller, preferably 10-50% smaller, more preferably 15 to 40% smaller than the original cavity before collapse and is preferably re-usable, although single use or several use adaptors are employable as well.
  • a particularly significant aspect of the invention is the reduced volume of a package as compared with a package of conventional rolls of cored product with the same weight and sheet count. Volume reductions of about 10 to about 20%, about 14% to about 20%, 30%, 40% and more are realized while delivering the same quality and quantity of product without incurring excessive aesthetic objections.
  • the central cavity of the hollow coreless roll, prior to compression of the roll, is typically cylindrical with a diameter in the range of 25-75 mm.
  • the invention is superior to core-in compressed products in terms of reduced weight and in terms of re-formability of the central cavity as will be appreciated from the discussion provided hereinafter.
  • the invention product In contrast to conventional hollow coreless products with small central axial cavities, the invention product has a relatively large central cavity and the product is much more compressible, making available the benefits in terms of volume reduction and product shape. Conventional hollow coreless products are also difficult to re-shape after compression to a stable “round” shape.
  • the present invention makes it possible to overcome consumer negatives associated with producing desirable combinations of sheet count and caliper without needing to achieve specific roll diameter requirements.
  • Current rolled products have desired roll diameters for specific characterizations like “Regular Roll”, “Large Roll”, Big Roll”, “Giant Roll”, Mega Roll”, “Super Roll”, “Double Roll” and similar other size related descriptions.
  • sheet counts are reduced, it becomes more and more difficult to achieve the desired roll diameter, whether by increasing base sheet caliper, finished product caliper (i.e., through more emboss, higher basis weight, high bulk forming), or through winding the roll in a way that results in a large diameter, but low overall fiber weight, roll.
  • the present invention also provides for multiple packaging options for a plurality of rolls.
  • Packages of multiple rolls in accordance with the invention require less storage space and can be configured to fit into spaces not suitable for conventional products; making it possible to better utilize available storage areas in the home or in a business establishment.
  • the tissue rolls in the compressed configurations also adapt well to limited storage and display spaces found in retail environments. Savings in transportation costs can be of immense importance commercially.
  • each roll of compressed absorbent paper product may be wrapped in a polyethylene film formed from a tube flattened and heat sealed between rolls so that each roll is ensconced in its own separate sub package while a linear array of wrapped rolls may be manipulated like a string of sausages to adapt to storage in oddly sized or configured spaces that may be available.
  • it will be convenient to provide two heat sealed regions separated by one line of weakness in the portion of the tube between adjacent rolls so that the rolls may be easily separated from the linear array while remaining individually sealed from the environment.
  • the distance between at least some of adjacent rolls will be at least substantially equal to the transverse dimension (width) of the compressed roll to make it convenient to dispose the rolls in serpentine configurations.
  • each individualized roll will bear a transverse circumferential band to stabilize the compression.
  • a transverse circumferential band may comprise paper, a similar nonwoven or a polymeric film.
  • it will be expedient to secure the transverse band by interposing pressure sensitive adhesive between overlapping ends thereof.
  • that packaging will itself be sufficient to retain the rolls in the compressed configuration.
  • the rolls may be expedient to compress the rolls using opposed pistons.
  • the rolls may be compressed by forcing them through a suitably shaped chute.
  • FIG. 1A is a photograph showing a compressed hollow coreless roll of bath tissue of the invention.
  • FIG. 1B is a photograph showing a compressed roll of bath tissue with a paperboard core prepared by the same method of compression as the roll of FIG. 1A .
  • FIG. 2A illustrates a re-formed hollow coreless roll of bath tissue in accordance with the invention.
  • FIG. 2B illustrates a re-formed roll of bath tissue with a paperboard core.
  • FIGS. 3A, 3B and 3C are views in perspective of a re-usable core which may be used for dispensing tissue from the roll of FIG. 2A .
  • FIG. 4 illustrates a package which contains four rolls disposed in a 1 ⁇ 4 planar array with the collapsed axial cavities of the compressed rolls arranged in parallel and the longer sides of the compressed rolls arranged in facing relationship.
  • FIG. 5 illustrates a package which contains four compressed rolls disposed in a 2 ⁇ 2 planar array with the collapsed axial cavities of the compressed rolls arranged in parallel.
  • FIG. 6 illustrates a package which contains four compressed rolls, two of which are disposed centrally with their collapsed axial cavities arranged in parallel between two other outer rolls wherein the collapsed axial cavities of the outer rolls are arranged perpendicularly with respect to the collapsed axial cavities of the centrally located compressed rolls.
  • FIG. 7 illustrates a package which contains four compressed rolls disposed in a stacked 2 ⁇ 2 array with the collapsed axial cavities of two pairs of stacked compressed rolls arranged coaxially and wherein the longer side of the compressed rolls arranged in facing relationship to each other.
  • FIG. 8 illustrates a package which contains four rolls disposed in a 1 ⁇ 4 array with the collapsed axial cavities of the compressed rolls coaxially arranged.
  • FIG. 9 illustrates a package which contains four rolls disposed in a 1 ⁇ 4 array with the collapsed axial cavities of the compressed rolls arranged in parallel and wherein the shorter sides of the compressed rolls are arranged in facing relationship.
  • FIGS. 10A through 10G are schematic diagrams which illustrate volume savings of the invention products as compared with uncompressed product having a paperboard tubular core packaged in a 2 ⁇ 2 planar array. It can be appreciated that savings in volume extend over a wide variety of configurations from single rolls up to over-wrapped pre-packaged store displays holding hundreds of rolls of tissue in any of a variety of subpacks on a single pallet that can be simply positioned on the retail floor and sold individually after removal of the overwrap.
  • FIGS. 11A through 11D illustrate schematically how a hollow roll of tissue, having its core previously removed, may be uniaxially compressed using opposed pistons producing an elliptical void wherein the long walls of the ellipse are nearly planar and parallel to each other, preferably touching, or nearly so, along most of their length.
  • FIG. 12 is a schematic illustration of a four pack of hollow compressed tissue rolls encased in a hollow polymeric tube which has been heat sealed between the hollow compressed rolls to form a flexible pack which can be disposed in a very large number of configurations.
  • FIG. 13 is another schematic illustration of a four pack of hollow compressed tissue rolls encased in a hollow polymeric tube which has been disposed in another configuration.
  • FIG. 14 is another schematic illustration of how three four packs of hollow compressed tissue rolls encased in a hollow polymeric tube may be disposed in an overall configuration forming a twelve pack.
  • FIG. 15 is another schematic illustration of how six four packs of hollow compressed tissue rolls encased in a hollow polymeric tube may be disposed in an overall configuration forming a twenty-four pack.
  • FIG. 16 is a schematic illustration of how twelve hollow compressed rolls of tissue may be disposed in a single elongated polymeric tube to form a flexible package which can be configured in a large number of postures.
  • the length of the portions of the hollow polymeric tube between adjacent rolls has been exaggerated to more clearly show the heat sealed regions and lines of weakness formed in that portion of hollow polymeric tube between rolls.
  • FIG. 17 is another schematic illustration of how three four packs of hollow compressed tissue rolls encased in a hollow polymeric tube may be disposed in an overall configuration forming a twelve pack.
  • FIG. 18 is another schematic illustration of how six four packs of hollow compressed tissue rolls encased in a hollow polymeric tube may be disposed in another overall configuration forming a twenty-four pack.

  • FIGS. 26A through 26D schematically illustrate a packing scheme in which poly-wrapped 6 roll packs of un-cored compressed kitchen roll towel are palletized in cartons yielding another particularly efficient truckload of tissue.
  • the reference is to a flattened form as shown in FIG. 1A .
  • the gap between opposing sides of the cavity in the substantially collapsed configuration is less than 25 mm, preferably less than 10 mm, more preferably less than 5 mm and still more preferably less than 2 mm on average.
  • opposing sides of the collapsed cavity are in contact over a major portion of their area, preferably over at least about 60%, more preferably over at least about 70%, even more preferably over at least about 80%, and most preferably at least about 90%, when rolls are in the compressed state in which they are shipped.
  • Tissue rolls or similar terminology refers to cellulosic fiber tissue products, while “bath tissue” rolls must be flushable and are typically manufactured without a substantial amount of permanent wet strength resin; as opposed to paper toweling, or kitchen roll towel, which has a substantial amount of wet strength resin.
  • the most preferred bath tissue is predominantly (over 50% dry weight) composed of hardwood fiber such as eucalyptus fiber, although many grades, particularly commercial and economy grades, have ever increasing recycled content of uncertain origin.
  • Bath tissue generally has a basis weight of anywhere from 8 to 35 lbs per 3000 square foot ream, with 2 and 3 ply products typically having a basis weight of from 20 to 35 lbs per 3000 square foot ream. Details and various properties of bath tissue are presented in U.S. Pat.
  • relative orientation of the compressed rolls in the package is specified, in part, by reference to a central axis of the collapsed axial cavities of the compressed rolls which corresponds to the axis of the forming core member upon which the sheet is wound during manufacture and/or converting. Relative orientation is also sometimes specified by reference to either a longer or shorter sides of the compressed rolls.
  • FIG. 1A there is shown a compressed hollow coreless roll 10 of absorbent paper sheet produced by way of providing a roll of absorbent paper sheet by winding the sheet about a forming core member having a diameter in the range of 25 mm to 50 mm; removing the forming core member such that there is provided a hollow coreless roll of absorbent paper sheet with an axial cavity having a diameter in the range of 25 mm to 50 mm and compressing the hollow coreless roll such that the axial cavity is substantially collapsed.
  • a “hollow” compressed roll we are referring to a roll of tissue from which either a conventional cylindrical board stock tube has been removed or a roll of tissue from which the central portion of the roll has been removed leaving a hollow cavity therethrough. Note the absence of any hollow cylindrical board stock core in central cavity 12 of the compressed hollow coreless roll 10 of FIG. 1A .
  • central plugs Prior to compression, central plugs are preferably removed from substantially hollow coreless rolls using the procedures such as those described in U.S. Pat. No. 7,992,818 to Maddaleni, Aug. 9, 2011 (incorporated herein by reference). Subsequent to core removal, hollow coreless roll 8 may be compressed by action of opposed pistons 70 , 72 bearing against lateral surfaces of the rolls as illustrated in FIGS. 11A through 11D , resulting in compressed hollow coreless roll 10 .
