As lanes are removed from the stack, the moveable component slides along the slot until it reaches the central portion of the lattice-shaped member. The spring force may be effective to provide support but not so high as to distort the lanes in the stack. Other mechanisms and devices to provide a biasing force using the lattice-shaped divider will be recognized by the person of ordinary skill in the art, given the benefit of this disclosure. In some instances, the inward projection may be moveable along some portion of the lattice-shaped divider to provide a biasing force against the side of the stack.
In some examples each absorbent article present in a layer may comprise a core layer and a backing layer. The term layer, as used in reference to each absorbent article, is used herein for convenience purposes only and the various materials used in the absorbent articles can be configured as a film, sheet, patches or take other forms. In use of the absorbent articles, the core layer typically contacts an object (not shown) and is effective to absorb fluid from the object. The backing layer typically provides a supportive structure to the core layer. In some embodiments, the backing layer may have a total weight of at least 50 grams per square meter (gsm), more particularly at least 90 gsm, at least 100 gsm or at least 150 gsm. In certain embodiments, the backing layer can have a desirable lamination strength. In certain embodiments, the core material can comprise a material effective to absorb and/or retain fluids. In some examples, the core material 110 can comprise a polar material. In other examples, the core material can comprise a material comprising a plurality of hydroxyl groups. In yet other examples, the core material can comprise cellulose or cellulose-based materials. In some embodiments, the core material can comprise a fiber mat comprising cellulose fibers sized and arranged as a loose non-woven material. In some embodiments, the core material can comprise a basis weight of about 100 grams/square meter to about 175 grams/square meter, e.g., about 110 g/square meter to about 150 grams/square meter. In some instances, different core materials may be present in different absorbent articles in a particular layer.
In certain examples, the core layer can be selected such that fluid that contacts the article becomes absorbed and trapped by the core layer. In certain instances, the physical and mechanical properties of the core layer can be selected to provide desired properties to the article. In some configurations, the basis weight of the core can be from about 80 gsm to about 160 gsm, more particularly about 100 gsm to about 150 gsm, for example, about 110 gsm to about 140 gsm. In certain embodiments, the basis weight of the core can be from one or more different materials present in the core. For example, where an absorbent material such as a superabsorber is present, the absorbent material may be present from around 5 gsm to about 50 gsm, more particularly about 10 gsm to about 40 gsm, for example about 25-35 gsm or 30 gsm. In some embodiments, the core may also include tissue, pulp or other types of paper or cellulose based material that can be present, for example, from about 20 gsm to about 100 gsm. Where tissue is present, the tissue can be present, for example, at a basis weight of about 15 gsm to about 60 gsm, more particularly about 25 gsm to about 50 gsm, e.g., about 30 gsm to about 45 gsm. Where pulp is present in the core, the pulp can be present from about 30 gsm to about 80 gsm or from about 40 gsm to about 70 gsm, for example about 45 gsm to about 65 gsm. The particular thickness of the core material may also vary depending on the desired use of the article. In some embodiments, the core material can be about 0.4 mm to about 2 mm thick, more particularly about 0.7 mm to about 1.5 mm thick, for example, about 0.8 mm thick to about 1 mm thick.
In certain embodiments, the pattern (if present) on the core material or core layers may vary depending on the desired aesthetic appearance and/or equipment used to produce the article. In some embodiments, one or more of a pinpoint pattern, square pattern, circular pattern, triangular pattern, rectangular pattern, hexagonal pattern or other geometric shapes may be present. In some instances as described herein, a pattern may be imparted to the core layer by using a roller comprising the particular pattern during manufacture of the article. In certain examples, the thickness of the overall article can vary from about 1 mm to about 2 mm, more particularly by about 1.2 mm to about 1.7 mm. In addition, the thickness of the article need not be uniform.
In other embodiments, additional materials can be present in the core layer, backing layer or both. For example, in certain embodiments one or more superabsorbent materials can be added, mixed with or otherwise disposed in the core material either prior to processing, during processing or after processing. Without wishing to be bound by any particular scientific theory, a superabsorber can act to absorb and/or retain large amounts of fluid. Illustrative superabsorbers are described, for example, in WO94/10596 and specific superabsorbers include, for example, acrylate composites, sodium polyacrylate, an acrylonitrile polymer, a polyacrylamide copolymer, an ethylene maleic anhydride copolymer, a cross-linked carboxymethylcellulose, a polyvinyl alcohol copolymer, a cross-linked polyethylene oxide, a starch grafted copolymer of polyacrylonitrile and other commonly available superabsorbent polymeric materials. In some embodiments, the process used to provide the core material may not include the use of any binders. In certain embodiments, the process used to provide the core material may be performed at room temperature and/or in ambient air. In certain examples, the core material can be produced as described in U.S. Pat. No. 6,675,702, the entire disclosure of which is incorporated herein by reference.
In one illustrative process for producing the absorbent articles, a core material can be produced by forming a web of material and coupling the formed web to a backing layer. In some embodiments, cellulose fiber comprising fluff pulp, e.g., dry wood pulp cardboards produced by means of a hammer mill, can be used to provide the core material. In one embodiment, a layer of fibers, e.g., typically present in irregular or random orientations, can be conveyed to a first pair of calender rollers on a strainer conveyer belt. One of the rollers can be heated or have a desired surface temperature, e.g., 200-220° C., while the other roller can remain unheated. If desired, the web can be moisturized, coated or sprayed with a desired substance prior to entering the gap between the two rollers. In some embodiments, the resultant moisture content of the material is about 5 to 10 percent by weight. During passage of the material between the rollers, the moisture content can be reduced from the use of the heated roller. After passage through the rollers, the cellulose fibers are compressed to provide a loose non-woven. The non-woven can be moisturized, coated or sprayed with a desired substance after exiting the rollers.
In certain embodiments, the loose non-woven can be provided to a pair of calender rolls. The loose non-woven can be subjected to an array of point-shaped pressure zones, where the irregularly arranged fibers are pressed onto each other under high pressure, such that a close fusion of the fiber bodies occurs and a fiber web with a desired pattern can be provided that generally will not separate after the pressure is released. The particular pattern is not critical and illustrative patterns include pinpoint patterns, square patterns, circular patterns and other geometric patterns. The pressure used can result in “melting” of the fiber materials and provide close bonding. For example, through focused high pressure and crowding of the fibers, the loose cellulose or pulp fibers can be bonded together in free spaces resulting in an overall very strong fiber web. The calendar rolls can be operated at room temperature, e.g., between 18-25° C., but one or more of them may also be heated if desired. In some examples, the pressure provided by the calender rolls can vary between 100 to 600 MPa, e.g., 500 MPa, but higher pressures can also be used. In certain examples, the resulting fiber web of material can comprise a basis weight, for example of about 50-1500 g/square meter. The fiber web exiting the calenders is significantly more tear resistant than the web entering the calender rolls. In some examples, the resulting fiber web may then be provided to a drawing roller, and, if desired, wrapped onto a take-up roller with the use of a driver roller.
In certain examples, the loose material provided to the first set of rollers can be an inexpensive mass material that is available in large amounts. For example, fluff pulp with a whiteness of 85 to 89% can be used, which in turn means that a significant lignin and residue content is still present, which can assist in improving the bonding behavior. The fiber length of the material can vary and is desirably long enough such that they bridge the distance between the pressure zones. The additives described herein can be used, for example, in various amounts. In some instances, fluff pulp can be supplemented with superabsorbers with 0.5 to 70 percent in weight, preferably 5 to 30 percent in weight, and thereafter sent through the high-pressure calender rolls. The superabsorbers generally have no bonding effect but become trapped in the non-woven once it is processed.
In certain embodiments, the core material can be produced without the use of any binding agents. By producing the core material without using any binding agents, the recyclability and compostability of the product is improved. In addition, the production becomes less expensive and is simpler because stations for applying and curing are not required. In other embodiments, if desired, the core material can be produced using one or more binding agents or binding agents may be used to couple the core material to the backing layer and/or top layers as described herein.
In some embodiments, the finished core material may comprise numerous irregular cellulose fibers that are coupled by fusion in the pressure zones. The material itself can comprise a high tear strength and, in addition, a high absorption capacity, which is increased even further through the use of superabsorbers such that it can be used as packaging material, for hygiene articles other articles described herein.
In certain examples, the finished core material can be glued, welded, laminated or otherwise coupled to a backing layer, film or sheet. The backing layer may be pre-coated with an adhesive and coupled to the core material using one or more additional roller pairs to press the core material against the backing layer. Depending on the type of adhesive used, ultraviolet light, visible light, heat or other stimulus may be applied to the resulting composite to assist in curing of the adhesive.
In some instances, the backing layer can be produced using one or more thermoplastics or may include one or more thermoplastics. Thermoplastics provide desirable attributes including enhanced flexibility, desirable weight-to-strength ratios and easy processing. Illustrative thermoplastic materials include, but are not limited to, a polyethylene, a polypropylene, a polybutylene terephthalate, a polyester-polypropylene, a polyethylene terephthalate, an acrylonitrile butadiene styrene, a cellulose acetate, an ethylene-vinyl acetate, an ethylene vinyl alcohol, a fluoroplastic such as polytetrafluoroethylene, a polyoxymethylene, a polyacrylate, a polyacrylonitrile, a polyamide, a polyamide-imide, a polyetheretherketone, a polyaryletherketone, a polybutadiene, a polybutylene, a polycaprolactone, a polychlorotrifluoroethylene, a polyetherketoneketone, a polycarbonate, a polycyclohexylene dimethylene terephthalate, a polyhydroxyalkanoate, a polyketone, a polyester, a polyetherimide, a polysulfone, a polyimide, a polylactic acid, a polymethypentene, a polyphenylene oxide, a polyphenylene sulfide, a polyphthalamide, a polystyrene, a polytrimethylene terephthalate, a polyurethane, a polyvinyl acetate, a polyvinyl chloride, a polyvinylidene chloride, a styrene-acrylonitrile, combinations thereof and other suitable thermoplastics. In some embodiments, the backing layer can comprise two or more different thermoplastics. In other embodiments, the backing layer can comprise three, four, five, six, seven, eight or more different thermoplastics. In certain embodiments, the backing layer can comprise at least one thermoset and at least one thermoplastic material. In certain embodiments, the backing layer can be a non-woven material. For example, a non-woven material produced using a polyester and a polyethylene can be used as the backing layer. In other configurations, a non-woven material produced using a polyethylene and a polypropylene can be used as the backing layer. In additional configurations, a non-woven material produced using a polyester and a polypropylene can be used as the backing layer. In certain configurations, at least one of a polyethylene, a polypropylene, and a polyester is used in combination with another thermoplastic material to provide a backing layer suitable for use in an article.
In certain examples, a single sheet of backing layer can be used to provide a plurality of independent absorbent articles that may be separated by perforations. For example, the backing layer can be coupled to the core material by pressing, rolling, using adhesives, using laser welding, melting or other processing steps as described herein. In some examples, a hot-melt adhesive can be placed between the backing layer and the core material and the resulting composite can be heated to couple the backing layer to the core material. If desired, the composite can be passed through rollers, placed into a press or mold or otherwise a desired amount of pressure can be applied using suitable methods such as those described in U.S. Pat. No. 6,675,702, for example. Once the adhesive has cured, the composite sheet can be perforated in desired areas such that an article or articles of a desired size may be produced by tearing or separation at the perforations. For example, in a typical operation a sheet comprising of 2, 4, 6, 8 or more lanes of individual and separate articles can be produced. In some examples, perforation lines can be present between lanes and/or between rows of the layers.
In certain configurations, additional layers, e.g., cover layers or other layers can also be present in the absorbent articles. For example, it may be desirable to include a top layer on the absorbent core layer to provide for additional functionality or for aesthetic reasons. In some examples, the top layer may comprise one or more thermosets or thermoplastics as described herein. For example, where the top layer comprises a thermoset, the thermoset may be, for example, a polyester-fiberglass system, vulcanized rubber, a phenolic resin, a phenol-formaldehyde resin, a urea-formaldehyde foam, a melamine resin, a melamine-formaldehyde resin, an epoxy resin, a polyimide, a cyanate ester, a polycyanurate, a polyester thermoset such as, for example, an unsaturated polyester that can be cross-linked and other suitable thermoset materials and combinations of thermoset materials. If desired, the thermoset can be used with one or more cross-linking agents to facilitate setting of the material during processing. In some examples, the top layer can comprise two or more different thermosets. In other embodiments, the top layer can comprise three, four, five, six, seven, eight or more different thermosets. Where the top layer comprises a thermoplastic, the thermoplastic may be, for example, a polyethylene, a polypropylene, a polybutylene terephthalate, a polyester-polypropylene, a polyethylene terephthalate, an acrylonitrile butadiene styrene, a cellulose acetate, an ethylene-vinyl acetate, an ethylene vinyl alcohol, a fluoroplastic such as polytetrafluoroethylene, a polyoxymethylene, a polyacrylate, a polyacrylonitrile, a polyamide, a polyamide-imide, a polyetheretherketone, a polyaryletherketone, a polybutadiene, a polybutylene, a polycaprolactone, a polychlorotrifluoroethylene, a polyetherketoneketone, a polycarbonate, a polycyclohexylene dimethylene terephthalate, a polyhydroxyalkanoate, a polyketone, a polyester, a polyetherimide, a polysulfone, a polyimide, a polylactic acid, a polymethypentene, a polyphenylene oxide, a polyphenylene sulfide, a polyphthalamide, a polystyrene, a polytrimethylene terephthalate, a polyurethane, a polyvinyl acetate, a polyvinyl chloride, a polyvinylidene chloride, a styrene-acrylonitrile, combinations thereof and other suitable thermoplastics. In some embodiments, the top layer can comprise two or more different thermoplastics. In other embodiments, the top layer can comprise three, four, five, six, seven, eight or more different thermoplastics. In certain embodiments, the top layer can comprise at least one thermoset material and at least one thermoplastic material. In certain instances, a cellulose based material such as tissue, pulp or the like can be placed over exposed areas of the absorbent article. In some embodiments, two or more different materials can be added to the exposed areas. The material can be added in the form of a sheet, strips, segments or the like.
In certain embodiments, the overall thickness of the individual articles can vary depending on the intended use of the article. In some embodiments, the articles may be designed to be thin, e.g., 2 mm or less, whereas in other examples it may be desirable to increase the overall thickness of the article to provide for increased absorption, for example. In some embodiments, the thickness of the article can vary from about 1 mm to about 20 mm, more particularly, from about 1.5 mm to about 10 mm, for example, about 1.5 mm to about 9 mm, about 1.75 mm to about 5 mm or any value within these illustrative ranges.
In certain embodiments, the overall dimensions, geometry and shape of the article can vary. In some embodiments, the article can take the form of an individual pad with a width of about 4 inches by about 6 inches, more particularly a width of about 3 inches to about 5 inches, e.g., about 2 inches by about 2 inches by about 3 inches. In certain configurations, each layer of the absorbent articles may be about 12 inches to about 120 inches long, more particularly about 36 inches to about 96 inches long. In certain configurations, each layer of the absorbent articles may be about 12 inches to about 96 inches wide, more particularly about 24 inches to about 72 inches wide. In certain configurations, the dividers used herein can be sized and arranged such that they generally minor the width and/or length of the layers of the stack, whereas in other examples, the divider can be sized greater than or less than the dimensions of the stacks.
In certain embodiments, the articles can be sterilized prior to, during or after packaging in the containers. Many different sterilization methods can be used and desirably, non-moisture based sterilization methods are used so that the core material is not unnecessarily exposed to moisture prior to use. Illustrative types of sterilization methods include, but are not limited to, gamma radiation, electron beam radiation, X-ray radiation, ultraviolet radiation, ozonation, ethylene oxide gas exposure and other suitable non-water based sterilization methods. In some examples, the articles may be packaged in plastic or paper bags or receptacles, sealed from the ambient and then sterilized using one or more suitable methods and materials. In other examples, sterilization may take place prior to packaging or immediately prior to use of the article.
In certain examples, the articles described herein can include cosmetic agents. For example, the core material, top layer (when present) or both can include one or more cosmetic agents designed to provide a desired effect. Illustrative cosmetic agents include, but are not limited to, a moisturizer, a perfume, a sunblock, an exfoliant, a lotion, a powder, a polish, a sanitizer, a salt, a butter, a skin lightener, an anti-acne agent, an anti-wrinkle agent, a tanning agent, an oil, or other suitable cosmetic agents commonly applied to the skin of humans. In some examples, the article can be used with a cosmetic agent once the cosmetic agent has been applied to the skin or other desired area. For example, the cosmetic agent can be applied to the skin and then an article can be applied over the same area of the skin. In other examples, the article can be first applied to the skin to remove any unwanted moisture and then a cosmetic agent may be applied optionally followed by application of another article. For example, it may be desirable to apply the article to burn patients to remove residual moisture from the areas prior to application of desired cosmetic or therapeutic agents.
It will be recognized by the person of ordinary skill in the art, given the benefit of this disclosure, that the articles described herein can be configured or sized and arranged in many different forms, shapes and arrangements. In one embodiment, the articles described herein can be sized and arranged for use as a meat pad, a cosmetic pad, a surgical pad, a nursing pad, a feminine hygiene product, a diaper, a helmet or hat insert or other uses. For example, the dimensions of the article may be similar to, or the same as, the packaging used to package meat products such as, for example, beef, pork, chicken, lamb or other meats. For example, each of the individual absorbent articles can be used to absorb fluids from surfaces to prevent growth of mold, bacteria or other organisms of the surfaces. For example, the articles can be placed in food packaging to absorb water or moisture within the package to prevent the food from being exposed to the water. In some examples, the articles may be placed in shipping crates, plastic bags or other forms of packaging commonly used to ship and/or sell food products such as produce, meats, cheeses or other foods.
In some embodiments, the articles described herein can be used as liners for shelves in pantries, refrigerators or other areas where it may be desirable to remove moisture. For example, sections of the article may be cut or the article may be sized and arranged to be inserted into crisper drawers or placed on refrigerators shelves to absorb excess moisture from food products in the refrigerator. In some examples, the article can be used with an insert designed to retain the article in place or the shelf or drawer may include fittings, tabs or holder to hold the article in place during use.
In certain examples and referring to
In placement of the stacks 1500, 1550 into a container, a temporary divider or insert can first be inserted during stacking of the layers. The temporary divider may not be thick enough or comprise a suitable material to provide any substantial support, but may assist in keeping the layers in stack 1500 from interleaving in the layers of stack 1550, which could lead to processing complications. In some instances, the temporary divider may be a flexible or bendable material such as paper, a plastic, a metal such as aluminum, a laminate or the like. In some instances, the height of the temporary divider is less than the height of the final stacks in the container. For example, the temporary divider can be inserted until about 50% of the final height of the stack and then it can be removed. In some instances, the temporary divider is removed and followed by placement of one of the dividers described herein, e.g., a U-shaped divider, a Z-shaped divider, an X-shaped divider, a C-shaped divider, a lattice shaped divider or other dividers. In other instances the temporary divider may remain in place and sit adjacent to the support divider or may be crushed or flattened by insertion of the support divider into the container.
To produce the various layers of the articles, a continuous roll process can be used to form the articles on a backing layer, e.g., to form a plurality of individual articles on a common backing layer. The formed articles can be rolled over a feed roller that can move forward and backward to layer the articles in a container. In some instances, one or more press rollers or crimpers may be present to press the backing layer at fixed locations to provide a crease between layers. A generalized schematic of such a system is shown in
In certain embodiments, the containers used herein may comprise a bottom portion and a top portion. Referring to
In certain configurations, the dividers described herein can permit loading of additional absorbent articles into the containers compared to a container lacking a divider. For example, a single container may comprise 20,000 or 30,000 or even 40,000 or more absorbent articles. The absorbent articles can be present in lanes with anywhere from 2-12 lanes, for example, of absorbent articles being present in any one layer. The dividers can be used in packaging technologies other than absorbent articles including, for example, table napkins, textiles, removable paper notes, and other similar applications. The exact length and width of the dividers can vary depending on the particular configuration of the divider, and illustrative lengths are from about 72 inches to about 120 inches, e.g., about 80 inches to about 108 inches or about 90 inches to about 100 inches long. Illustrative widths include, for example, about 24 inches to about 60 inches, more particularly about 32 inches to about 48 inches, e.g., about 36 to about 44 inches.
Certain specific examples of dividers are described in more detail below.
In one configuration, a divider is produced from corrugated cardboard (44 ECT strength) with a length of about 92 inches and a width (height) of about 40 inches. The cardboard is formed into a Z-shaped divider that generally bisects the width of the container.
In another configuration, a divider is produced from corrugated cardboard (44 ECT strength) with a length of about 92 inches and a width (height) of about 37 inches, which can be less than the overall height of a container comprising the stacked layers. The cardboard is formed into a Z-shaped divider that generally bisects the width of the container.
In one configuration, a divider is produced from corrugated cardboard (44 ECT strength) with a length of about 92 inches and a width (height) of about 40 inches. The cardboard is formed into a U-shaped divider.
In one configuration, a divider is produced from corrugated cardboard (44 ECT strength) with a length of about 92 inches and a width (height) of about 37 inches, which can be less than the overall height of a container comprising the stacked layers. The cardboard is formed into a U-shaped divider.
