DETAILED DESCRIPTION OF THE INVENTION

(21) Previous packaging methods included disposing a plurality of products in a shipping container such as, for example, a corrugated box or shipping carton. The shipping container consumed material and energy resources. The exemplary methods and apparatus described below include embodiments that allow a plurality of products to be shipped and stored without the use of a shipping carton.

(22) The term sheet products as used herein is inclusive of natural and/or synthetic cloth or paper sheets. Sheet products may include both woven and non-woven articles. There are a wide variety of nonwoven processes and they can be either wetlaid or drylaid. Some examples include hydroentagled (sometimes called spunlace), DRC (double re-creped), airlaid, spunbond, carded, paper towel, and meltblown sheet products. Further, sheet products may contain fibrous cellulosic materials that may be derived from natural sources, such as wood pulp fibers, as well as other fibrous material characterized by having hydroxyl groups attached to the polymer backbone. These include glass fibers and synthetic fibers modified with hydroxyl groups. Examples of sheet products include, but are not limited to, wipers, napkins, tissues, rolls, towels or other fibrous, film, polymer, or filamentary products.

(23) In general sheet products are thin in comparison to their length and breadth and exhibit a relatively flat planar configuration and are flexible to permit folding, rolling, stacking, and the like. The sheet product may have perforations extending in lines across their width to separate individual sheets and facilitate separation or tearing of individual sheets from a roll or folded arrangement at discrete intervals. Individual sheets may be sized as desired to accommodate the many uses of the sheet products. For example, perforation lines may be formed every thirteen inches, or other defined interval, to define a universally sized sheet. Multiple perforation lines may be provided to allow the user to select the size of sheet depending on the particular need.

(24) FIG. 1 illustrates an example of a roll of sheet product (roll) 100. The roll of sheet product 100 may include a cylindrical core in the center of the roll 100. Alternate embodiments, however, may not necessarily include a cylindrical core. FIG. 2 illustrates another example of rolls of sheet products 200. The rolls 200 have a shorter cylindrical height than the roll 100 and are arranged so as to be stacked on-end.

(25) FIG. 3 illustrates an example of the roll 100 (of FIG. 1) that has been wrapped in a protective cover 302. The protective cover 302 envelopes the roll 100. The protective cover 302 may be formed from any suitable material such as, for example, a plastic or a fibrous sheet product. The protective cover 302 may be transparent, translucent, or opaque, and may include graphics or text printed on the protective cover 302. FIG. 4 illustrates an example of the rolls 200 (of FIG. 2) that are individually wrapped in a protective cover 402. The protective cover 402 is similar to the protective cover 302 (of FIG. 3) described above.

(26) FIG. 5 illustrates an arrangement of the rolls 100 (of FIG. 1). In this regard, three rolls 100 are arranged in-line and are packaged in a protective cover 502. In the illustrated embodiment, the protected cover 502 may be fabricated from, for example, a plastic or fibrous sheet product material that may be transparent, translucent, or opaque. In an alternate embodiment, the wrapped arrangement of the roll 100 that includes the protective cover 302 (of FIG. 3) may be incorporated into the illustrated embodiment of FIG. 5 such that each roll 100 may be individually wrapped in a protective cover 302. The wrapped rolls 100 may then be arranged in-line, and subsequently wrapped in the protective cover 502.

(27) FIG. 6 illustrates an arrangement of the rolls 200 (of FIG. 2) that are stacked on-end and arranged in-line in a similar manner as the rolls 100 of FIG. 5. The illustrated arrangement of the rolls 200 is wrapped in a protective cover 602 that is similar to the protective cover 502 (of FIG. 5). In an alternate exemplary embodiment, the rolls 200 may be individually wrapped in the protective cover 402 (of FIG. 4) prior to wrapping the rolls 200 in the protective cover 602.

(28) FIG. 7 illustrates an exemplary embodiment of an arrangement of rolls 100 that have been secured by a band 702. In the illustrated embodiment, the rolls 100 have been arranged and wrapped in a similar manner as the rolls 100 of FIG. 5 described above. Thus, the rolls 100 have been arranged in-line and wrapped in groups of three rolls. Five of the groups of rolls 100 are arranged and secured by the band 702. The band 702 may be formed from, for example, a plastic material that may have elastic properties. The band 702 exerts a compressive force on the arrangement of rolls 100, securing the rolls 100 in the illustrated arrangement. In the illustrated embodiment, an example of a longitudinal axis of the rolls 100 is shown by the line 707, and edges of the band 702 define a plane illustrated by the lines 709 and 711. The band 702 is arranged circumferentially about the rolls 100, such that the plane defined by the lines 709 and 711 is arranged substantially orthogonal to a longitudinal axis of the roll 100 (shown by the line 707). In the illustrated embodiment, the band 702 is formed from two rectangular strips 703 and 705 of material that are connected together at opposing seams 701 (only one seam shown in FIG. 7, the other seam being hidden from view on the opposite side of the arrangement of rolls), using a connecting process such as, for example, a plastic heating, welding, or bonding process. In alternate embodiments, the band 702 may be formed from a single strip having opposing ends connected together with a single seam 701. The material that forms the band 702 may be printed with graphic or textual markings in, for example, the regions 704, prior to forming the band 702. The process used to connect the strips 703 and 705 of material is operative to form the seams 701 without appreciably deforming the band 702 (except, in some embodiments, in the regions proximate to the seams 701). Thus, the connecting process does not deform the regions 704 that may include graphical, opaque regions, or textual markings in the regions 704. The process may also index the orientation of the strips 703 and 705, such that the arrangement of the regions 704 remains uniform as subsequent bands 702 are formed in mass production. Though the illustrated embodiment includes five groups of three rolls 100, alternate arrangements may include, for example, any number of groups of three rolls 100 or any number of groups of rolls 100 having any number of rolls 100 per group. The dimensions and shape of the regions 704 of illustrated embodiment are shown for illustrative purposes. The regions 704 may be any shape or size including covering any or all areas of the band 702.

(29) FIG. 8A illustrates an exemplary embodiment of the arrangement of rolls 100 (shown in FIG. 7) above that has been wrapped in a wrapper 802. The wrapper 802 envelopes the rolls 100 and the band 702. The wrapper 802 is formed from a plastic material that may be heated to shrink the wrapper 802 around the rolls 100 and the band 702. The wrapper 702 may be formed from, for example, a tubular shaped plastic material that is arranged about the rolls 100 and the band 702. The wrapper 802 may be transparent or translucent and may, or may not include graphic or textual markings printed on the wrapper 802. If a heating process is used to shrink the wrapper 802, the heating process shrinks the wrapper 802, without appreciably shrinking or deforming the band 702. Thus, the graphical and textual markings on the band 702 remain formed and intact, and may be legible and visible through a transparent wrapper 802. The shrinking of the wrapper 802 in the illustrated embodiment forms orifices 804 that may expose portions of the band 702. In the illustrated embodiment, although a single orifice 804 is shown, another orifice 804 has been formed on the opposing side of the arrangement (not shown in the FIG. 8A). The orifice 804 may aid in allowing heat to dissipate from the heating process (that shrinks the wrapper 802). The dissipation of the heat via the orifice 804 reduces the possibility of undesirably deforming the band 702 while shrinking the wrapper 802. The illustrated embodiment includes a line of perforations 801 that may be formed to assist a user in manually removing the wrapper 802 without using a cutting tool, for example. In the illustrated embodiment, the line of perforations 801 intersects the orifice 804. In alternate embodiments, however, the line of perforations 801 may be arranged in any suitable manner.

(30) The wrapper 802 may be formed from a material having desirable friction properties to, for example, increase the ease in handing a packaged product. In this regard, the wrapped product may be handled in a variety of automated or semi-automated systems such as conveyer belts, shoots, and rollers. A plurality of packaged products may be grouped together and moved using gripping type lift devices. It is desirable for the wrapper 802 to have a surface with a coefficient of friction that meets design parameters, for example, to allow motive rollers to propel a package or a lift device to grip multiple packages with less slippage between packages than a wrapper 802 having a lower coefficient of friction.

(31) FIG. 8B illustrates an alternate exemplary embodiment of an arrangement of rolls 100. In this regard, the rolls 100 are arranged and secured by the band 702. The banded rolls 100 are disposed on a rigid or semi-rigid sheet or pad 806 that may include, for example, a corrugated material. The wrapper 802 is formed around the rolls 100, the band 702, and the pad 806 in a similar manner as discussed above. The pad 806 or a similar arrangement may be included in any of the discussed embodiments.

(32) FIG. 9 illustrates an arrangement of rolls 200 that is similar to the arrangement of rolls illustrated in FIG. 8A. In this regard, the rolls 200 are stacked on-end, grouped and wrapped in a wrapper 602, as shown in FIG. 6. The rolls 200 are grouped as illustrated, secured by a band 702, and wrapped in a wrapper 802.

(33) FIG. 10 illustrates an exemplary embodiment of an arrangement of products 1001 that are rectangular prism-shaped and secured by a band 702, and wrapped in a wrapper 802 in a similar manner as described above. Though the illustrated embodiments include cylindrical and rectangular prism-shaped products, the methods and embodiments described above may be used for products having any variety of shapes. In an embodiment, each product 1001 is a stack of paper napkins oriented such that the band 702 wraps around outer surfaces of the arrangement of products 1001 to securely hold the arrangement.

(34) FIG. 11A illustrates an exemplary embodiment of an arrangement of rolls 100 that are individually wrapped in a protective cover 302, as described above in FIG. 3. The rolls 100 are arranged in rows 1101a-1101d. The rows 1101a and 1101b are secured by a band 702a and the rows 1101c and 1101d are secured by a band 702b. The banded products are arranged adjacent to each other and wrapped in a wrapper 802 in a similar manner as described above.

(35) FIG. 11B illustrates an exemplary embodiment of an arrangement of rolls 100 that are individually wrapped in a protective cover 302, as described above with respect to FIG. 3. The rolls 100 are arranged in rows and secured by bands 702a and 702b in a similar manner as discussed above with respect to FIG. 11A. The rows secured by the band 702b are stacked onto the rows secured by the band 702a. The stacked rolls are wrapped in a wrapper 802 in a similar manner as described above.

(36) FIG. 12 illustrates an exemplary embodiment of an arrangement of tableware products 1202. The tableware products 1202 may include, for example, paper, plastic, foam, or alternate material formed in the shape of a plate, a bowl, a platter, a tray, or other type of tableware. The tableware products 1202 are packaged in groups that are wrapped in protective covers 1203. A band 1204 that is similar to the band 702 (of FIG. 7) secures the arrangement of the tableware products 1202. The arrangement of tableware products 1202, and the band 1204, are wrapped in a wrapper 802 in a similar manner as described above.

(37) FIG. 13 illustrates another exemplary embodiment of an arrangement of tableware products 1202. The tableware products 1202 are arranged in two rows. The band 1204 secures the arrangement of the tableware products 1202. The arrangement of tableware products 1202 and the band 1204 are wrapped in a wrapper 802 in a similar manner as described above.

(38) FIG. 13 illustrates an exemplary embodiment of an arrangement of tableware products 1202. The tableware products 1202 are arranged in two rows. The band 1204 secures the arrangement of the tableware products 1202. The arrangement of tableware products 1202 and the band 1204 are wrapper 802 in a similar manner as described above.

(39) FIG. 14 illustrates an exemplary embodiment of an arrangement of sheet products that may include, for example, stacked sheets of paper packaged in a paper or plastic protective cover 1402, resulting in a rectangularly prism-shaped product package 1404.
