Definitions

  • the disclosure relates to embossed absorbent paper products, such as bath tissue, facial tissue, and paper towels and to methods of making such paper products.
  • Absorbent paper products such as bath tissue, facial tissue, and paper towels are well known. Such products are commonly used in households, businesses, restaurants, shops, and the like. Often absorbent paper products are embossed to provide an aesthetically pleasing look to an exposed surface of the absorbent paper product. Embossing is also known to be useful for aiding in bonding multiple plies of absorbent paper together to form a multi-ply absorbent paper product.
  • absorbent paper products are also well known.
  • absorbent paper products are made by wet laying processes in which a fibrous slurry of cellulosic fibers is deposited on a forming wire and thereafter dried by known processes such as through-air-drying, press felts, and Yankee drum drying.
  • Absorbent paper products can be creped or non-creped, and can be converted after drying into multi-ply, embossed, and/or rolled absorbent paper products.
  • a rolled absorbent paper product having an emboss design pattern visible on an outside layer that facilitates identification of a manufacturer.
  • a rolled absorbent paper product having an emboss design pattern visible on an outside layer that reinforces to a user during use the product the identification of a manufacturer.
  • a rolled absorbent paper product includes an absorbent paper substrate having at least one ply with an emboss pattern comprising two visually distinct emboss design elements disposed in a plurality of predetermined, spaced- apart positions across the ply.
  • the two emboss design elements comprise a first emboss design element occupying all but at least one of the positions in a first repeating pattern, and a second emboss design element occupying the at least one of the positions not occupied by the first emboss design element.
  • the second emboss design element can be a word comprising a line emboss defining line-embossed letters wherein each letter comprises an open area within the line emboss.
  • the first and second emboss design elements can each have an emboss area of from about 7% to about 25% and a difference in emboss area relative to each other of less than about 10%.
  • FIG. 1 is a photograph of a rolled absorbent paper embodiment of the present invention.
  • FIG. 2 is a plan view of a representative emboss pattern of the present invention.
  • FIG. 3 is a photograph of a portion of an emboss roll embodiment of the present invention.
  • FIG. 4 is a schematic diagram of one example of a repeating emboss pattern useful in the present invention.
  • FIGS. 4A-4C are representative emboss design elements.
  • FIG. 5 is a plan view of an example of a surface of an emboss roll of the present invention.
  • FIG. 5 A is a magnified view of a portion of the emboss roll of FIG. 5.
  • FIG. 6 is a representative depiction of a portion of a line-embossed word emboss element of the present invention.
  • FIG. 7 is a cross sectional representation of cross section 7-7 of FIG. 6.
  • FIG. 8 is a representative depiction of a portion of a line-embossed word emboss element of the present invention.
  • the present invention is an absorbent paper product having at least one ply with an emboss pattern comprising two visually distinct emboss design elements disposed in a plurality of predetermined, spaced apart positions across the product.
  • the absorbent paper product can be a facial tissue, bath tissue, paper towel, napkin, or the like, and can be provided in roll form, as is common for bath tissue and paper towels.
  • the absorbent paper of the absorbent paper product can be any of known absorbent paper known for use as facial tissue, bath tissue, paper towel, napkin, or the like, and will not be described in detail herein.
  • absorbent paper suitable for use in the present invention include the absorbent paper utilized in currently marketed facial tissues including PUFFS® and KLEENEX®, currently marketed bath tissues such as CHARMIN®, COTTONELLE®, ANGEL SOFT®, and ULTRA NORTHERN®, currently marketed paper towels such as BOUNTY®, VIVA®, and BRAWNY®.
  • any absorbent paper product made by known papermaking methods, including wet laying and through air drying, and which can be embossed can be utilized in the present invention. Therefore, the description below is non-limiting with respect to the particular absorbent paper product to be embossed, the particular manufacturing method, or the particular format (e.g., rolled or stacked/interleaved).
  • FIG. 1 shows a roll 10 of absorbent paper product 12.
  • the absorbent paper product 12 shown in FIG. 1 is a paper towel product, which has been wet laid, through air dried, and creped, as is known in the art, prior to being embossed with the pattern shown.
  • the pattern shown in FIG. 1 is representative only.
  • the absorbent paper product 12 can have two visually distinct emboss design elements, a first emboss design element 14, which in FIG. 1 includes two concentric diamonds, and a second emboss design element 16, which in FIG. 1 is in the form of the brand name BOUNTY®.
  • First emboss design element 14 can be any shape, design, or combination of shapes and designs, and can be included with other emboss elements, such as the wavy line design 18 formed from relatively closely spaced dot embossments 20.
  • visually distinct emboss design elements are design elements that can be visually distinguished as discrete, separate design elements, which design elements can be disposed in a regular, substantially repeating pattern, as shown in FIG. 1 (only one of second emboss design element 16 is shown in FIG. 1).
  • the emboss design elements disclosed herein are disclosed as representative only, and virtually any emboss design element can be utilized for either first or second emboss design elements.
  • a roll of absorbent paper product 10 which has been embossed can include an emboss design element which is a source identifier, i.e., a logo, a trademark, or a brand name, such as BOUNTY® as shown in FIG. 1.
  • the brand name can be the second emboss design element 16, and can be spaced in any pattern at predetermined positions according the present invention. Having the manufacturer's and/or marketer's logo, trademark, or brand name embossed in a visually distinct emboss element on an absorbent paper product assures that the consumer, or other user, can readily identify the manufacturer and/or marketer of the absorbent paper product during use.
  • the consumer can be reminded of the manufacturer and/or marketer and the manufacturer's and/or marketer's brand equity can be reinforced to the consumer. If the consumer likes the absorbent paper product, he or she can be reminded during use of the source, and can be better informed to make the same purchase next time he or she shops for absorbent paper products.
  • FIG. 2 shows a portion of a web of absorbent paper product 12.
  • absorbent paper product 12 can be made on wet-laid papermaking machines, which as is known, in commercial operations produces parent rolls of absorbent paper product having a machine direction MD and a cross direction CD.
  • the MD represents the direction of travel as the absorbent paper product is being made on the paper machine.
  • the CD represents the cross direction, which at its maximum is the width of the web of paper as it is being made (or the width of a finished paper product, such as a paper towel).
  • Absorbent paper product 12 can have spaced apart lines of weakness 24, which can be in the form of perforations, which in the finished product facilitate tearing off one sheet at a time.
  • rolled absorbent paper products such as bath tissue and paper towels typically have perforations which permit the user to tear off a sheet (or a plurality of sheets) at the location of the perforation.
  • the parent roll can be cut by a log saw to produce a plurality of finished rolls of a predetermined width. As shown in FIG. 2, the log saw can cut along lines 32 to form a finished roll having a roll width W.
  • the solid lines 34 forming two adjacent rectangles in FIG. 2 are intended to represent two individual, adjacent sheets 36 of a finished roll of absorbent paper product, such as a finished roll of paper towels in a Select-a-Size® format.
  • Each sheet 36 is defined in the CD by the settings of the log saw which cuts the parent roll, and in the MD by the spacing of lines of weakness 24.
  • emboss design elements occupy positions 22 which can be predetermined positions, each position of which can be occupied by either a first emboss design element 14, or a second emboss design element 16, or no emboss design element.
  • positions 22 can be determined by the use of a grid 26, which can be an imaginary, or digitally overlaid, grid which does not actually appear on the absorbent paper product 12, but which can be a tool for conceptualizing and designing an emboss pattern.
  • a portion of a representative grid 26 is shown in FIG. 2.
  • a grid 26 of the present invention can be a grid of parallel straight lines 28 in the machine direction, MD, intersecting with parallel straight lines in the cross direction, CD.
  • positions 22 are predetermined to be every other intersection in both the MD and the CD.
  • positions 22 can be any predetermined location on the absorbent paper product 12 at which a designer desires an emboss design element. In practice, it can be typical to make such design elements in a regular, repeating pattern.
  • a first emboss design element 14 can be disposed in a substantially regular, repeating pattern at most of the positions 22, with the exception of the positions 22 at which are disposed second design emboss elements 16.
  • emboss design elements that can also be utilized on commercial embossing equipment as is known in the art.
  • Known embossing rollers typically provide for a nip between a rubber roll and a steel roll, or two steel rolls.
  • all manner of roll types, number of rolls, materials, and nip configurations can be employed in the present invention.
  • the patterned emboss roll can be balanced; that is, the pattern can be designed such that the area occupied by emboss elements is substantially equal as a percentage across the face of the emboss roll.
  • the emboss design element (and portions of emboss elements) encompassed in that area has an area of emboss that is substantially equal to the area of emboss for the specified area at every other position 22 having emboss elements. Therefore, the number of positions is not important, but the spacing and placement can be designed to ensure that on average the area of emboss surrounding each position 22 is substantially equal across the face of the emboss roller.
  • first emboss design elements 14 and second emboss design elements 16 can have substantially equal emboss areas relative to each other, such that when spaced generally regularly in a repeating pattern at some or all of positions 22, the emboss roll can be balanced.
  • a balanced emboss roll experiences less wear and, therefore, lasts longer with fewer other mechanical problems such as excessive vibration, than an unbalanced roll.
  • first and second emboss design elements each have an emboss area of from about 7% to about 25%, including every tenth of a percent between 7% and 25%, for example 16.9%.
  • the relative difference between the emboss area of first emboss design element 14 and second emboss design element 16 can be less than about 10%, or less than about 7%, or less than about 5%, or less than about 3%.
  • Emboss area of an emboss element in an embossed absorbent paper product can be determined by considering the area of the emboss roll elements which produced the emboss in the embossed absorbent paper product, the emboss roll elements producing a close approximation in area on the embossed absorbent paper product.
  • the emboss area of an emboss element can be determined by utilizing a visual image in which emboss elements are outlined, either by hand or electronically, and the emboss area determined by mathematical calculations.
  • first and second emboss design elements can be varied for the desired visual impression desired by the manufacturer or marketer of the absorbent paper product.
  • the number, spacing and placement of second emboss design elements 16 can be sufficient to ensure that at least one second emboss design element 16 at least partially intersects with a line of weakness 24, as shown in FIG. 2.
  • the number, spacing and placement of second emboss design elements 16 can be sufficient to ensure that at least two, or at least 4, or at least 6, or at least 8, or at least 10, or at least 12 second emboss design elements 16 at least partially intersects with a line of weakness 24. As shown in FIG. 2, for example, each second emboss design element 16 at least partially intersects with a line of weakness 24. It is not necessary that every second emboss design element 16 at least partially intersects with a line of weakness 24, but at least one can.
  • the advantage of producing a rolled absorbent paper product in which one or more second emboss design elements 16 intersects at one or more lines of weakness 24 is maximized when the second emboss design element 16 is a source identifier, such as a logo, brand name or trademark.
  • a source identifier such as a logo, brand name or trademark.
  • the logo, brand name, or trademark can be embossed by providing for the logo, brand name, or trademark on the emboss roll, such as the representative emboss roll 38 shown in FIG. 3.
  • the emboss roll 38 shown in FIG. 3 can be a steel roll manufactured by means known in the art for steel emboss rolls.
  • the mating roll (not shown) can be a rubber (or other soft-surface) roll, or a mating steel roll, as is known in the art.
  • the representative emboss roll 38 shown in FIG. 3 produces an emboss pattern on absorbent paper product 12 as shown in FIGS. 1 and 2.
  • first emboss roll element 40 including two concentric diamonds corresponds to first emboss design element 14, and a second emboss roll element 42 of the brand name BOUNTY® corresponds to second emboss design element 16.
  • additional emboss roll elements such as the point (or dot, or spot) emboss roll elements 44 can be disposed in a closely spaced arrangement to form a wavy line emboss roll pattern 46. With respect to determining roll balance and percent area of emboss elements at any given position 22, the point emboss roll elements 44 can be taken into account.
  • the emboss roll 38 can have a pattern of regularly spaced first emboss roll elements 40 where at certain of positions 22 a second emboss roll element 42 can be substituted so as to provide for a periodic embossment of a logo, brand name, or trademark, while maintaining relatively little percent emboss area difference between first emboss roll elements and second emboss roll elements (including, as necessary, other surrounding emboss elements such as point emboss roll elements 44).
  • first emboss roll elements and second emboss roll elements including, as necessary, other surrounding emboss elements such as point emboss roll elements 44.
  • second emboss roll element 42 may displace, i.e., replace, some of the point emboss roll elements 44 that form wavy line emboss roll pattern 46.
  • the number of point emboss roll elements 44 that are displaced can be adjusted depending on the size and emboss area of the line embossment elements of second emboss roll design elements 42 so as to maintain a relatively low emboss area difference between first emboss roll elements 40 and second emboss roll elements 42.
  • FIG. 4 can represent a design drawing pattern repeat, as well as represent the pattern of the first emboss roll elements 40 or, correspondingly, when applied to the absorbent paper product in an embossing unit operation, FIG. 4 can represent a pattern repeat of the first emboss design elements 14 in the finished absorbent paper product 12.
  • the method for how to calculate an emboss element area can be accomplished to a close, working approximation by calculating the area of emboss roll 38 elements.
  • an inscribed area 48 can be determined, such as by defining a closed perimeter, such as circle 50, centered about position 22.
  • the inscribed area 48 need not be a circle, but can be any shape sufficient to inscribe at least one emboss element, such as a square, as shown in FIGS. 4A-4C, sufficient to inscribe emboss roll element 40.
  • the inscribed area 48 can also inscribe or partially inscribe other emboss elements as long as a consistent inscribed area 48 is applied to all positions 22 occupied by an emboss roll element.
  • the area of the flattened faces F (as shown in FIG. 7, which is a representative cross-sectional depiction of all emboss roll embossments of the present invention) of emboss roll elements, such as the paper-contacting outer surface of the line elements making up first emboss roll elements 40 (and portions thereof, as shown in FIG. 4, in which inscribed area 48 includes parts of the four outer first emboss roll elements 40), as well as point emboss roll elements 44.
  • the area of the substantially flat faces of the various emboss roll elements can be added to arrive at a total area of embossment.
  • the total area of embossment can be divided by the inscribed area 48 to arrive at a percent emboss area for any given emboss elements around a position 22 at which emboss elements are centered.
  • the inscribed area 48 can be a square, and the second emboss design element can include line embossed letters (FIG. 4A) or block-embossed letters (FIG. 4C).
  • Block-embossed letters which are letters in which the entire letter is embossed, can be used for the logo, brand name, or trademark of the second emboss design element, but, of course, will have a higher emboss area.
  • the percent emboss area for first emboss elements 16 can be substantially equal to the percent emboss area for second emboss design elements 14 (and, correspondingly, second emboss roll elements 42).
