  • folds are nested within other folds and there is only one free edge available to the user. The user must unfold each fold to be able to utilize the entire sheet.
  • Wipes are commercially available saturated or coated with substances that a user may want to avoid or limit their contact.
  • wipes are commercially available with such substances as disinfectants, cleaning solutions, detergents, astringents, medications, and other chemicals.

  • All types of products and materials can benefit from particular folding configurations. As discussed above, folding an article allows for more efficient packaging, storage and transport of the article. Articles that can benefit from an improved folding configuration include articles that are commonly folded such as napkins, facial tissue, towels, and wipes. Other items such as medical drapes, bedding, blueprints and maps also are commonly folded and could benefit from an improved folding configuration. This is only a partial, and non-limiting, list of articles that can folded in accordance with the present invention. As such, the present invention extends to all articles and materials that can be folded in the manner described below. For exemplary purposes, the discussion of the present invention will be directed to articles in a generic sense and to wipes as a specific example of an article that can be folded in accordance with present invention.
  • Wipes as discussed within, are useful for personal, household, commercial and industrial cleansing applications.
  • Common wipes include baby wipes, face wipes, hand wipes, cosmetic wipes, household wipes, industrial wipes and wipers, and the like.
  • Materials used to form a wipe of the type contemplated here are generally well known in the industry.
  • Such base materials may include natural fibers, such as cellulosic fibers, synthetic fibers and polymers, or combinations thereof. These fibers are converted into sheet substrates by a variety of processes that are also generally well known in the industry.
  • Wipes can be made of a single substrate layer or may be made of multiple layers of substrate.
  • a wipe made of multiple layers of substrate may have similar material substrates in each layer or may be made of differing substrate layers.
  • Such substrates may include, but are not limited to, woven fabrics, nonwoven fabrics, synthetic films (cast or extruded), tissue paper (heavy wet creped, light dry creped or through air dried), air laid paper, and the like.
  • Exemplary processes for forming the substrates include, but are not limited to, the tissue processes found in U.S. Patent Nos. 6,149,767 and 6,331 ,230, both to Hermans et al.; the nonwoven processes found in U.S. Patent Nos. 4,604,313 to McFarland et al., 4,820,577 to Morman et al., and 4,784,892 to Storey et al.; coforming processes as found in U.S. Patent No.
  • Wipes can be wet or substantially dry.
  • a substantially dry wipes are often used to absorb fluids and particulates from surfaces.
  • Wet wipes are commonly found in personal hygiene applications such as baby wipes and hand/face wipes. Both wet and dry wipes often include additional substances that give the wipe additional utility.
  • Additional utility that can be added to the wipe include, but is not limited to, cleaning solutions, antibacterial formulations for sanitizing and/or disinfecting, detergents, diapering medicines, moisturizing lotions, suntan lotion, electro-statically charged zones, odor absorbing chemicals, odor neutralizing enzymes, insect repellent, and the like.

  • the sheet may generally be square in shape.
  • a folded strip is formed by zigzag folding of a sheet in a first direction, followed by zigzag folding of the folded strip in a second direction, the second direction being substantially perpendicular to the first direction.

Regardless of the number of parallel folds used to make the folded strip, it is preferred that those folds be made in a zigzag fashion. As discussed before, such zigzag folding requires that each adjacent fold is made in the opposite direction as the adjacent fold. In other words, such a zigzag fold is a series of "Z-folds" which are commonly understood in the art to be a fold series that resembles the alphabet character for which it is named.
  • Both the folded strip 101 of FIG. 1 and the folded strip 202 of FIG. 2 were then zigzag folded along two parallel fold lines substantially perpendicular to the fold lines used to form the folded strips.
  • the folded strip could be folded by a greater number of parallel folds than the two folds described with regard to FIGS. 1 and 2.
  • the number of zigzag folds made to the folded strip should be an even number of folds greater than zero (i.e., 2, 4, 6, 8, etc.).

  • the corners that are present on the uppermost and bottommost surfaces of the folded article, as described for FIGS. 1 and 2, are the diagonally opposite corners of the unfolded sheet. By grasping and pulling these two available comers away from each other, the folded article will easily and fully unfold the sheet material. The user is thus able to fully unfold the folded article while contacting the folded article only at the two diagonally opposite corners.
  • the method of folding the folded strip an odd number of zigzag folds may be advantageous for an article with a large area.
  • a larger article may be of a size such that the diagonally opposite corners are too far apart for a person to easily pull the article open by pulling the diagonally opposite corners apart. The larger the object is on the diagonal, the wider the user will have pull the corners apart, requiring longer arms or the assistance of another person.
  • the large article is folded such that the folded strip is folded by an odd number of zigzag folds, the user would only have to spread the corners of the same side apart (a span that is shorter than the diagonal).
  • Such a large object may also have enough weight in its layers that the folded strip may unfold itself with the help of gravity.
  • the fold configuration as described for and shown in FIGS. 1 and 2 produces a folded article that is easy to open. By grasping and pulling the exposed corners apart, the user can open the folded article.
  • the process of opening the article can be aided by providing the user with one or more pull indicia that indicate where the user should grasp the article.
  • Such pull indicia can be any sensory cue that will allow the user to find the location where they should grasp and pull on the folded article.
  • the cues will generally be visual or tactile in nature, but auditory, olfactory and gustatory cues are not precluded.
  • the pull indicia may be the corners themselves as they are present on the uppermost and bottommost surfaces of the folded article. The user can visually identify such a comer on each such surface or will be able to feel the location of such a corner by running a finger over such surfaces.
  • the corners can be further distinguished by folding the corner over as shown in FIG. 2.
  • FIG. 2 the first and third corners 25, 26 were folded over in the first step of the folding process, but the same corners could alternatively be folded over as the last step of forming the folded article 203.
  • Such folded corner pull indicia present on the uppermost and bottommost surfaces of the folded article may act as both a visual and tactile cue; indicating the location of the corner and acting as a tab for the user to grab and pull.
  • the apex of the corner may be removed, cut into a unique shape, or otherwise distinguished from other corners.
  • Other visual cues that could act as a pull indicium could include the use of colors, textures, symbols, logos or the like.
  • the material to be folded may have different colors, or different shades of color, on one face versus its reverse face.
  • the corners present on the uppermost and bottommost surface will be more noticeable due to the difference in color of the corner versus the background material the corners rest against. Such a color difference could be further used to enhance a folded corner pull indicium, as discussed above.
  • a visual cue would be a printed edge pattern, similar to the one used in FIGS. 1 and 2 as a folding reference.
  • a printed edge pattern could be solid color, a geometric pattern, or a repeated symbol, logo, or a message.
  • the printed edge, pattern 18 points to the corners 15, 16 of the folded article 102 that are to be grasped and pulled to open the folded article 102.
  • the printed edge pattern 28 as present in FIGS. 2 and 2B is shown as printed only on one side of the sheet. This one-side printing provides the folded over corners 25, 26 with a pull indicia of contrasting pattern to the surfaces 292, 293 on which the corners 25, 26 are folded over.
  • a symbol, logo, shape, message, or similar marking could be used in the area of the corner to be pulled as a pull indicium. Rather than printing the entire sheet edge with a pattern, a discrete marking could be made in the area to be grasped and pulled.

  • the pull indicia may be tactile in nature.
  • the sheet may have a distinctly different texture on one face versus the reverse face.
  • the corners present on the uppermost and bottommost surface will be more noticeable due to the difference in texture in the corner versus the texture of the material the corners rest against.

  • the sheet 200 can then be folded as shown in FIG. 2 and the pull indicia of folded corners 25, 26 will appear on the outermost surfaces of the folded article 203. All of the above pull indicia could be used singularly or in combination.
  • the individual pull indicium used on the areas to be grasped and pulled can be the same for both areas to be grasped or may be different.
  • the pull indicia can be any sensory cue that will allow the user to locate the areas to be grasped and pulled to open the folded article.
  • the pull indicia discussed above are only examples and are not intended to be limiting.
  • Such folded articles could be packaged as individual packets, or a multitude of such folded articles could be stacked and packaged together.
  • Such multiple- article stacks could be packaged in plastic film packaging, a box, a hard shell container, or any other type of container adapted to containing such a stack of folded articles.
  • Such containers may be additionally adapted to dispensing the folded articles.
  • a stack of such folded articles may consist of multiple folded articles placed directly on top of each other.
  • the individual folded articles of the stack may be interfolded or possibly interleaved.
  • An interfolded or interleaved stack is generally the preferred method of stacking folded articles for use in a container adapted for dispensing such folded articles.
  • a wipe is an article that would benefit from the particular folding configuration of the present invention.
  • folded wipes are often folded in such a way that can be difficult to open and often are a source of frustration to those who attempt to unfold and use them.
  • sheets that are used for wipes measure in the range of about 4 inches by 4 inches to about 8 inches by 12 inches (about 100mm X 100mm to about 200mm X 300mm).
  • such a wipe is folded into a size in the range of about 1 inch by 1 inch to about 3 inches by 4 inches (about 25mm X 25mm to about 75 mm X 100 mm). Larger and smaller folded wipes and larger and smaller unfolded sheets are also considered to be within the scope of the invention.
  • the wipe sheet could be folded by the fold configuration of the present invention to produce a folded wet wipe having corners on the uppermost and bottommost surfaces which the user could grasp and pull away from each other to easily open the folded wipe.
  • Such a wipe could be folded into a size that can be individually packed (i.e., between about 1 inch by 1 inch and about 3 inches by 4 inches).
  • a folded wipe that is substantially square in shape is preferred due to its ease in packaging.
  • Such individual folded wipes are either placed into a pre-made packet or they are individually wrapped with a film material to form the packet around the folded wipe.
  • packets are generally made of polyethylene or metalized cast polypropylene film.
  • Multiple individually folded wipes could be placed directly on top of each other to form a stack that could be packaged and sold.
  • a stack having 10 to 15 such folded wipes could be wrapped in a small plastic film ' packaging, such as used for facial tissue to produce what is commonly known as a pocket pack.
  • a larger number of folded wipes could be placed in a stack and packaged in a plastic tub or other types of enclosed packaging adapted to contain a stack of such folded wipes.
  • Such packaging might also be adapted to dispense such wipes.
  • packaging that is adapted to dispense such wipes generally use a stack of folded articles that are interfolded or interleaved such that when an individual wipe is removed from the packaging, the next wipe is presented and easily assessable to the user.
  • the first wipe 310 has a first strip fold 321 , which separates the first strip fold section 331 , from the second strip fold section 332, and a second strip fold 322, which separates the second strip fold section 332 from the third strip fold section 333.
  • the second wipe 410 has a first strip fold 421 , which separates the first strip fold section 431 , from the second strip fold section 432, and a second strip fold 422, which separates the second strip fold section 332 from the third strip fold section 433.
  • the first and second wipes 310, 410 are interleaved by putting them in relationship with each other such that the reverse face of the first strip fold section 431 of the second wipe 410 is in close proximity with the face of the third strip fold section 333 of the first wipe 310; the first corner 415 of the second wipe 410 will be nestled into the inside of the second fold 322 of the first wipe 310.
  • FIG. 4 illustrates a side view of the interfolding of the first wipe 310 and second wipe 410 as described above. When the first wipe 310 is removed from the stack, the first strip fold section 431 of the second wipe 410 will be accessible to the user.
  • the stack of folded wipes may be interleaved.
  • Interleaving or “interleaved” as the terms are used here refers to the stacking of individually folded articles where single corner found the bottommost surface of one wipe is overlapped by the single corner found on the uppermost surface of the underlying wipe or a folded section of the underlying wipe. It can also refer to the overlap of a folded section of the overlying wipe by a single corner found on the uppermost surface of the underlying wipe. When the overlying wipe is removed from the stack the top corner, or top section, of the underlying wipe will then be accessible to the user.
  • the removal of the overlying wipe will pull on the underlying wipe in such a way as to make part of the underlying wipe accessible to the user. While the overlying wipe's ability to pull on the underlying wipe is partially due to the interaction of the folds, some degree of surface-to-surface resistance is required between the two wipes. This resistance may be provided by the wet nature of the wipes which causes them to cling to one another. Alternatively, the wipes could be mechanically bonded, crimped, co-apertured or ultrasonically bonded in one or more points such that the overlapping surfaces of the wipe stick together. Finally, the surface-to-surface resistance could be increased through chemical bonding or the use of adhesives over some portion of the interacting surfaces.
