STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT 
     N/A 
     BACKGROUND OF THE INVENTION 
     The term “wipes” may refer to a variety of disposable cleaning and/or disinfecting sheets of cloth or cloth-like material. Wipes may be provided dry as with the common facial tissue or pre-moistened as with well-known baby wipes, depending upon the intended use. The type of paper or non-woven media and the liquid used for moistening have gone through many changes over time as improved materials and new applications have been identified. 
     However, the packaging and delivery systems employed for wipes dispensing has not similarly evolved. For example, the predominant packaging mode employed in the current marketplace is a rectangular box having a top-opening door or a lid enabling access to the uppermost one of an interleaved stack of wipe sheets. Such geometries may be cumbersome and inconvenient for personal use. They may also overly expose moistened wipes to the atmosphere, leading to premature evaporation of the moistening agent and drying of the wipes. 
     Identifying a suitable, efficient delivery mechanism for pre-moistened wipes configured in a continuous roll of severable, consecutive wipes has been a challenge in the industry, particularly with respect to defining a package that is easily and unobtrusively portable. What is required is a simple to use, efficient, low cost, and refillable delivery mechanism for rolls of wipes, especially for pre-moistened wipes. 
     Spools for use with rolls of various materials have been employed to enable smooth rotation of the roll within an enclosure. However, prior art spools have typically been cylinders having a continuous contact surface. Materials exhibiting a degree of adhesion do not release well from these spools. This is particularly true for commonly used low-cost spool materials including cardboard or molded plastic. At the same time, non-adhesive materials are prone to slipping about prior art spools, leading to irregular degrees of resistance while unrolling or dispensing the rolled materials. What is needed is a spool design that reduces the effect of adhesion for certain materials while enhancing the gripping effect between materials and the spool for non-adhesive materials. The materials in question may include rolls of wipes or similar goods. 
     BRIEF SUMMARY OF THE INVENTION 
     Disclosed is an injection molded dispenser configured to receive either one or two rolls of wipes materials. The edges and contours of the dispenser are rounded, reducing the presence of sharp corners or hard angles consistent with existing dispenser configurations. In a single roll configuration, the dispenser is provided with a side port enabling the removal of an outermost wipe from a point approximately mid-way along its leading edge. In a dual roll configuration, a side port is provided on opposing sides of the dispenser, adjacent a respective roll, similarly located approximately mid-way along the length of the dispenser and the rolls contained therein. The location of these ports substantially reduces the effects of torque on the wipes roll that would occur if the outermost wipe were removed from a point closer to either end of the respective roll. 
     As employed herein with respect to various types of dispensable tissue materials, the term “roll” may refer to a set of tissues which are consecutively attached and separable, and which are configured in a cylindrical form for subsequent dispensing, or may refer to a set of tissues, including inter-leaved tissues, which are configured so as to fit within a cylindrically shaped, or semi-cylindrically shaped, dispenser body. In the latter embodiment, a degree of frictional engagement may exist between consecutive tissue sheets, whereby removal or extraction of one sheet results in at least partial removal or extraction of the next consecutive sheet. 
     The cross-section of the dispenser may have one of a variety of shapes consistent with the requirement that it present no sharp corners or hard angles. Similarly, the ports may be may be sealed by one of a variety of removable caps, the caps being either independent and freely removable or unitary with the dispenser body and captive, such as through the use of a living hinge. For use with pre-moistened wipes, the port is preferably provided with an orifice that minimizes evaporative loss of moisture. In certain embodiments, the port orifice is configured to frictionally engage the next consecutive wipe, whereby as the outermost wipe is extracted from the dispenser the next wipe is retained substantially within the dispenser and the juncture between the wipes is separated. In one embodiment, the frictional engagement feature is integrally disposed into the dispenser body itself. 
     In an alternative embodiment, the frictional engagement feature is disposed within a curved barrier sheet that is disposed between the wipes roll and the dispenser body itself. Such a barrier sheet may be axially removable from the dispenser and be used to aid in loading a replacement roll of wipes into the dispenser. The barrier sheet may further find utility in retaining moisture, exuded from the wipes roll within the enclosure, thus preventing the moisture from accumulating proximate the enclosure port and leaking out onto a user or their purse, pocket, etc. The barrier sheet is preferably provided with an opening configured to frictionally engage a wipes sheet passing therethrough and to minimize evaporation of moisture within the wipes roll. 
     Preferably, one end of the dispenser is removable, thereby enabling the refilling of the dispenser with a replacement roll of wipes materials. A distal end of the dispenser is ideally provided with an axial projection configured to receive a spool upon which the wipes materials are wound. The removed end is also provided with a similar axial projection that is configured to for insertion into the spool upon reattachment of the end onto or into the dispenser body. Once so reattached, the roll is configured for smooth and free rotation on the spool and about the respective axis. 
     Also disclosed is an improved spool configuration for use with a roll of wipes material. The spool may be used with the presently disclosed wipes dispenser or may be adapted for use in other environments. The spool is provided with a plurality of linearly disposed channels on an outer, material-contacting surface thereof. The channels are preferably evenly spaced about the periphery of the spool. 
     Moist wipes may impart a greater degree of adhesion onto the spool when wound thereabout. By providing a plurality of such channels, the surface area between the spool and the terminal wipe or wipes is reduced. Thus, when the last wipe or wipes are extracted from the spool, less adhesion must be overcome, thereby reducing the strain imparted on the axial spindle projections supporting the spool. 
     In contrast, a roll of dry wipes may exhibit little or no adhesion to the spool. In this case, the channels form irregularities that frictionally engage the overlying wipes material, thereby preventing or reducing the degree of slippage between the wipes and the spool and ensuring constant resistance to wipes withdrawal is experienced by a user. The arcuate width of the channel is selected to enable this frictional engagement but is limited so as to not present a sharp edge that might cut or crease the wipes materials wound thereon. 
     In one embodiment, the channels are formed as perforations in the spool, forming an opening between the interior and exterior thereof. However, in an alternative embodiment, the channels are linear recesses formed in the spool. The latter is particularly desirable for use with pre-moistened wipes as it prevents the flow of moisture to the spool interior including through evaporation.

     DETAILED DESCRIPTION OF THE INVENTION 
     Disclosed is a novel dispenser for enabling dry or pre-moistened wipes, tissues, and other sheet-like materials, provided in rolled form, to be dispensed. Such a dispenser is referred to herein simply as a wipes dispenser though it is not necessary limited to dispensing wipes. A rigid or semi-rigid container is preferably provided with rounded surfaces to avoid sharp edges and corners. The container in one embodiment is provided as injected molded polypropylene or polyethylene. 
     A first embodiment of such a wipes dispenser  10  is illustrated in  FIG. 1 . The dispenser  10  is generally cylindrical with rounded ends. One such end is referred to as a fill cap  12  that is removable, thus providing access to the dispenser interior cavity so that a wipe roll or module may be inserted therein. An access cap  14  enables easy access to a next-to-be removed wipe or tissue. Preferably, both caps are capable of providing a moisture-tight seal, particularly in the case when pre-moistened wipes are to be dispensed. 
     The access cap  14  is disposed in cooperation with a side port  16 . The side port is preferably disposed mid-way along the length of the dispenser body  10 . When a wipe is removed from this centrally located port, torque is evenly distributed along the length of the roll; if the port were located at one end of the dispenser, torsional sheer stress could interfere with the even withdrawal of successive wipes and would stress the spindles upon which the spool is disposed. 
     In the dispenser embodiment illustrated in  FIG. 1 , a loop  18  is provided at one end of the body  10 , such as for attaching the dispenser to a spring-loaded D clip. The loop is not a required part of the disclosed dispenser, however. 
     The embodiment of  FIG. 1  is substantially circular in cross-section, as is evident from the cross-sectional view of  FIG. 2 , taken along lines  2 - 2  in  FIG. 1 . The fill cap  12  in a first embodiment is removably attachable through mutually aligned threads (not shown in  FIG. 1 ) on the cap and body  10 . Such rotation is suggested by the arrow in  FIG. 1 . 
     The dispenser embodiment illustrated in  FIGS. 3 and 4  is ideally suited for retaining two wipes rolls or modules in a side-by-side arrangement, as will be detailed below. This embodiment may be referred to as a dual dispenser. Access to the wipes contained therein is provided via a similar cap  14  and port  16  arrangement as depicted in  FIGS. 1 and 2 , though in this embodiment, two such cap and port arrangements are provided, one on each side of the dispenser  20 . 
     Since this dispenser embodiment has a non-circular cross-section, as is evident from the cross-sectional view of  FIG. 4 , taken along lines  4 - 4  in  FIG. 3 , the fill cap  22  is configured for sliding engagement with the body  20 , as suggested by the arrow in  FIG. 3 . A friction lock  24  is provided to selectively release the fill cap  22 . A more detailed discussion of the friction lock will follow. 
     The embodiment depicted in  FIG. 3  includes a loop  18  which is an optional component. 
     In all of the foregoing embodiments, for both the single and dual dispensers, the body and the fill cap, when joined, have no surface feature or surface transition that is ninety degrees or less, thereby presenting a rounded, comfortable to hold and carry body shape. 
       FIGS. 5A and 5B  illustrate alternative cross-sections of the single roll dispenser embodiment generally depicted in  FIG. 1 . The embodiment of  FIG. 5A  is circular, as is also shown in  FIG. 2 . The embodiment of  FIG. 5B  is ovoid. Note that if the single roll wipes dispenser of  FIG. 1  were to have the ovoid cross-section depicted in  FIG. 5B , the fill cap  12  would obviously not be threaded but instead would mate with the dispenser body  10  through other frictional means, to be discussed below. 
       FIGS. 5C and 5D  illustrate alternative cross-sections of the two roll wipes dispenser embodiment generally depicted in  FIG. 3 . The embodiment of  FIG. 5C  is oblong, whereas the embodiment of  FIG. 5D  is ovoid. 
       FIG. 6A  depicts a first embodiment of the access cap  14  and side port  16 . In the illustrated embodiment, the port is provided with a pliant membrane  30  that may be concave (as shown), flat, or convex. The membrane is provided with a discontinuity  32  that enables selective user access to an outermost wipe. For example, the discontinuity may be X-shaped (as shown) as defined by the gaps between a plurality of radially disposed pliant fingers. A user may grasp an outermost wipe by inserting part of one or more fingers into the discontinuity and pulling out part of the outermost wipe on a roll. Preferably, the pliant membrane  30  is sufficiently rigid to impart frictional force on a wipe as it is manually extracted from the dispenser  10  such that it engages and retains the next, consecutive wipe and a perforated juncture between the wipes is severed, leaving a leading portion of the next, consecutive wipe protruding from the discontinuity, as shown in  FIG. 6B . With the cap  14  closed over the side port  16  via friction fit, a substantially moisture-tight seal is created. The cap is preferably though not necessarily attached to the port  16  via a living hinge  38 . 
       FIGS. 7A through 7C  illustrate alternative embodiments of caps and side ports adapted to receive them in the body  10 . Note that these embodiments can also be used in conjunction with the body  20  adapted for holding two rolls. In  FIG. 7A , a cap  34  is retained on the port  16  via a living hinge  40  and mates with the port  16  via friction fit. The pliant membrane  36  in this embodiment is provided with an outwardly and downwardly extending collar region  42  that is inwardly threaded. The port  16  is provided with complimentary outwardly facing threads for engagement with the threads of the outwardly and downwardly extending collar region. The membrane is thus removable and may be replaced with other membranes, each having a distinct discontinuity (not shown). 
     The embodiment of  FIG. 7B  employs a friction fit cap  44  having a living hinge  48 , similar to that of  FIG. 6A . However, the port  46  is provided as a separable element, not integral with the body  10 , that is friction fit into the body via a channel groove  50 . The pliant membrane  52  is provided as integral to the port  46 . The port and membrane may be removed and replaced with another set having a different discontinuity. 
     In the embodiment of  FIG. 7C , the cap  54  is independent of the port  16  and is configured to snap onto a radial projection  56  of the port. 
     It will be recognized that a wide variety of combinations of ports, caps, and membranes is available, depending upon the specific application and design requirements such as cost and moisture-retention. 
       FIG. 8  is an elevation view of the wipes dispenser of  FIG. 1  with the fill cap  12  in place. As shown in  FIG. 1  by the large arrow, the fill cap is removed in a first embodiment by unscrewing it, the fill cap and the adjoining surface of the dispenser body  10  having complimentary threads  61 . In alternative embodiments, the fill cap may be friction fit onto the body in a manner similar to that demonstrated in  FIGS. 6B ,  7 B, and  7 C, and in these alternative embodiments, may or may not have a living hinge between the fill cap and the body. 
     In  FIG. 9 , the threaded fill cap has been removed and a curved barrier sheet  60  (also referred to as a retainer sheet) is visible extending from within the body  10 . As is seen in  FIG. 10 , the barrier sheet is configured to receive a wipes roll  62  within it, such that the barrier sheet and wipes roll substantially share a common axis of symmetry. The barrier sheet is provided with an aperture  64  through which a portion of an outermost wipe  66  is manually manipulated, as shown in  FIG. 14 . The aperture is preferably dimensioned to allow a single wipes sheet to be drawn therethrough. The aperture may be provided as a circular opening, as shown, whereby wipes are freely extractable. Once one or more desired wipes are removed, the user would grasp the next consecutive wipe and sever the junction connecting it to the last desired wipe. Alternatively, the opening may be configured such that wipes meet with frictional resistance as they are extracted, such that the perforated junction between consecutive sheets is severed upon sheet extraction. For example, the aperture  64  may be defined by the gaps between a plurality of radially disposed pliant fingers, such as shown in the membrane  30  of  FIG. 6A . If so provided, the membrane would not need to have the restricted discontinuity  32  such as shown in  FIG. 6A  and instead could be provided with a circular or other shaped opening, such as shown in  FIG. 15 . Further still, the membrane could be omitted altogether, as in  FIG. 7C  and  FIG. 16 . 
     As shown in  FIG. 11 , a wipes roll  62  is axially inserted into the barrier sheet  60 , which is disposed within the body  10 . Preferably, the barrier sheet is retained within the body such that it does not rotate with a wipes roll contained therein as one or more wipes are extracted. This is accomplished by disposing the barrier sheet within complimentary linear channels  68  formed on the interior surface of the body, as shown in in  FIGS. 12 and 13 . Such channels are preferably dimensioned to enable the barrier sheet to be freely moved into and out of the body by means of fingers of the user. 
     While a single wipes roll  62  is depicted in the wipes dispenser  10  of  FIG. 12 , two side-by-side rolls are schematically illustrated in the dual roll dispenser  20  of  FIG. 17 . Also visible in schematic form in  FIG. 17  is an optional dividing wall  70  between the rolls. Such a wall may completely separate the respective dispenser portions into which the rolls are disposed. This may be of use for a dual roll dispenser intended to retain rolls having disparate liquids contained therein, or one moist roll and one dry roll. Alternatively, the wall may be discontinuous and may simply serve to keep one roll from turning when a wipe associated with the other roll is being extracted. Further, the wall may facilitate the loading of a new roll and/or the unloading of an empty roll without interfering with the other roll. 
     Various fill caps may be employed for the dual dispenser  20 . As indicated in  FIG. 3 , a first embodiment of the fill cap is simply pulled straight off the body  20 , as indicated by the large arrow. The cap  22  in this embodiment has portions each with an aperture  25  that extends over and engages a respective friction lock  24  or button. When these buttons, on opposite sides of the dispenser, are manually depressed, towards the interior of the body, they disengage from the complimentarily shaped apertures  25 , allowing the cap  22  to be extracted. In  FIG. 18 , the fill cap  72  for the dual dispenser  20  is shown as having more of a squared off cross-section, though preferably the edges are still rounded to prevent user injury. Friction locks  24  are shown in the cross-sectional view of  FIG. 18 . Portions  71  of the fill cap  72  extend over complimentary portions  73  of the body  20  to ensure a secure fit and to assist in forming a moisture barrier. One or more resilient sealing surfaces (not illustrated) may be disposed between the cap and the body to further assist in forming a moisture barrier. 
     The fill cap  74  embodiment of  FIG. 20  is more rounded compared to that of  FIG. 18 . It is otherwise similar to the embodiment of  FIG. 18 . 
     The end caps  76 ,  78  of  FIGS. 19A and 19B  illustrate various configurations for the end caps proximate the interface between the caps and the body. 
     As shown in  FIG. 21 , the fill cap  22  of  FIG. 3  may alternatively be attached to the body  20  via a living hinge  23 , such that the cap swings in an arc towards a closed position, as evidenced by the large arrow. A locking portion  17  projecting from the cap  22  is provided with an orifice  19  that interferes with and engages a friction lock  24  on the body  20 . To open the cap, the locking portion is lifted outwardly and upwardly to disengage the friction lock. 
     The partial view of a single wipes roll dispenser of  FIG. 22  includes a variant of a fill cap  80  disposed on the body  10 . The cap is provided with a vertical projecting portion  90  that extends over a complimentary upward projection  88  of the body. Between the body  10  and the cap  80  is a sealing wall  84 , held in place on a notch  83  of the upward projection  88  of the body  10  by an internal pressure rib  82  acting on a foot  86  of the wall. Extending downwardly (as oriented in the figure) from the sealing wall is one of two complimentary projections or spindles  92 ,  94  (the other is shown in  FIG. 24 ) each adapted for receiving an end of a wipes roll spool therein. The spindles are preferably disposed coaxial with the axis of symmetry  87  of the body itself, regardless of the body cross-sectional shape. 
     The single roll dispenser sealing wall  84  of  FIG. 22  can also be adapted for use as a dual roll sealing wall  94  in the dual dispenser  20 , as shown in  FIG. 23 . Projecting downwardly from this sealing wall  94  are two spindles  93  (shown in phantom) such as the one  92  shown in  FIG. 22 . 
     One embodiment of the opposite end of the single roll dispenser  10  of  FIG. 22  is seen in  FIG. 24 . Preferably, a notch  98  is provided on the body  10  interior surface to fixedly receive a plate  96  bearing a complimentary spindle  94  over which a wipes roll spool can be disposed for rotation thereon. Attachment of the plate to the interior of the body may be through gluing, thermal welding, or any known means. The plate may also be formed integrally with the body. 
     A dual roll dispenser is preferably provided with a plate (not shown) similar to the single dispenser plate  96  in a closed end thereof, this plate having two upwardly projecting spindles akin to the upwardly projecting single spindle  94  of  FIG. 24 . Thus, in the dual dispenser embodiment, each of two rolls is suspended for rotation about a pair of mutually coaxial spindles. 
     A spool particularly adapted for use with the wipes dispensers of the present disclosure is depicted in  FIGS. 25 and 26 . This spool is particularly useful for wipes, as disclosed herein, though it can be adapted for a variety of uses. The spool may be formed of extruded plastic, cardboard, metal or any suitable material. 
     The spool  100  as illustrated is cylindrical in shape, with lateral grooves  102  disposed along its periphery, parallel to an axis of symmetry. In an alternative embodiment, the surface of the spool between grooves may be flat instead of curved, the latter shown in  FIG. 25 . While a total of eight lateral grooves are illustrated, more or less can be employed, depending upon the requirements of the application. The grooves shown in  FIG. 25  are provided as V-shaped recesses is the surface of the spool. In other embodiments, though, the grooves may be discontinuities or rectangular openings in the surface of the spool. The latter embodiment may not be suitable for moisture-bearing wipes since moisture from the roll may seep into the interior of the spool. 
     The grooves serve several beneficial functions. By reducing the surface area between the spool and the last wipe wound thereon, surface adhesion between the two is reduced. This is of particular benefit when the wipes are moisture-bearing. In the case where the wipes are not moisture-bearing, the grooves may serve the purpose of increasing the frictional interplay between the spool and the last wipe wound thereon. This then mitigates against the tendency for the dry wipes to slip with respect to the spool, thereby requiring an erratic degree of effort to extract wipes from the dispenser. 
     At either end of the spool  100 , a base plate  104  may be provided. An opening  106  is provided in each base plate, the diameter selected to enable the spool to mount and freely rotate on the spindles  92 ,  93 ,  94  illustrated in  FIGS. 22 ,  23  and  24 . Slots  108  may be provided as a means of preventing a vacuum to be formed within the spool and to reduce the friction between the spindles and spool. 
     The wipes dispenser of  FIG. 1  is particularly well-adapted to being portable. However, particularly in the case where the wipes are to be used for infants or small children, one-handed use of the dispenser may be required. To this end, a further embodiment of the dispenser may be provided with a T-shaped projection  110  that can be received within a slot-shaped bracket (not shown). The bracket may be wall-mounted, such as adjacent a baby changing station, enabling one-handed use of the dispenser. 
     A description of the process for refilling the single roll dispenser  10  is now provided, though it is understood that a similar procedure is used for a dual dispenser  20 . 
     A user may obtain a refill wipes roll. Rolls of moisture-bearing wipes may be packaged in waterproof secondary packaging, which is opened to extract the refill roll. The fill cap  12  is removed from the body, either by unscrewing it or disengaging it the lid from friction fitting. The barrier sheet  60  is removed or partly extracted and the roll is inserted into it. A free end of the outermost wipe is pulled through the aperture  64  and the barrier sheet is inserted into the L-shaped, parallel channels  68  on the interior surface of the body. The spool  100  is mounted onto the spindle  94  on the bottom of the body, and the sealing wall  84  is disposed on top of the spool, with the upper spindle  92  penetrating the exposed end wall  104  of the spool, then the fill cap is reinstalled. Alternatively, the sealing wall may be fixed within the fill cap and the fill cap with the sealing wall and spindle is inserted into the body and the spool. 
     In use, the access cap  14  is removed, either by disengaging a frictional fit to the port  16  or by unscrewing it. A user&#39;s digits are extended through the discontinuity  32  in the pliant membrane  30 , if provided, and a portion of the outermost wipe is removed. If a membrane is not provided, then the user pulls the free end from the curved barrier sheet. The cap is then closed. When a wipe is required, the cap is removed, the wipe is pulled from the port, and the serrations joining consecutive wipes are either separated due to the pulling force and the frictional engagement imparted by the membrane discontinuity or by a user separating the consecutive wipes.
