Definitions

• Wipes have been made from a variety of materials which can be dry or wet when used.
• Wet wipes can be moistened with a variety of suitable wiping solutions.
• Disposable moist wipes are often sold in rigid tubs or flexible pouches that include a dispensing orifice through which to extract the wipes from the interior of the tub or pouch.
• Such packages typically provide a sealed environment for the wet wipes to ensure that they do not become dirty or overly dry.
• a movable and resealable flap or lid typically covers the dispensing orifice, so that when a wipe is not being dispensed, the tub or pouch can be sealed to the outside environment to prevent moisture loss from the plurality of moist wipes housed therein.
• Mechanisms for opening the flap or lid vary.
• the lid In a common "push button” design, the lid is held closed via a latching mechanism. In the closed position, a compressed spring lies in tension against an undersurface of the lid. When an opening button is pressed, the latching mechanism releases the lid, and the compressed spring unloads its tension to throw the lid to an open position.
• Other mechanisms include simple hinge designs without such compressed springs. These lids may require the user to unlatch and fully open the lid.
• wet wipes have been stacked in a container in either a folded or unfolded configuration.
• containers of wet wipes have been available wherein each of the wet wipes stacked in the container has been arranged in a folded configuration such as a c-folded, z-folded or quarter-folded configuration as are well known to those skilled in the art.
• each folded wet wipe is interfolded with the wet wipes immediately above and below it in the stack of wipes.
• the wet wipes have been placed in a container in the form of a continuous web of material that includes perforations adapted to allow for separation of individual wet wipes from the web upon the application of a pulling force.
• Such wet wipes have been used for baby wipes, hand wipes, personal care wipes, household cleaning wipes, industrial wipes and the like.
• Some of the conventional packages have also been configured to provide "one-at-a-time” dispensing of each wet wipe which can be accomplished using a single hand after the package has been opened.
• Such single-handed, one-at-a-time dispensing is particularly desirable because the other hand of the user or care giver is typically required to be simultaneously used for other functions.
• "Pop-up” configurations of wet wipe dispensers can advantageously help provide the aforementioned single-handed, "one-at-a-time” dispensing.
• the wipe pulls along the leading end of the succeeding wipe in the package, by virtue of the succeeding wipe being in operative contact with the leading wipe such as via interfolding, via adhesive bonding, or via an integral connection along a line of weakness.
• the leading wipe is pulled out of and away from the package, the trailing end of the leading wipe breaks free from the leading end of the succeeding wipe, and the leading end of the succeeding wipe is left protruding from the package. In this way, the leading end of the succeeding wipe is immediately and automatically positioned for grasping and subsequent withdrawal from the package, and what was previously the succeeding wipe now becomes the leading wipe.

• FIG. 5 is a top plan view of the orifice 27 in isolation.
• the particular shape of the orifice 27, as described herein is an important contributor to successful dispensing with a low failure rate.
• successful dispensing may generally mean that, where a wipe is removed from the dispenser, the wipe pulls along the leading end of the succeeding wipe in the package, by virtue of the succeeding wipe being in operative contact with the leading wipe such as via interfolding, via adhesive bonding, or via an integral connection along a line of weakness.
• the trailing end of the leading wipe breaks free from the leading end of the succeeding wipe, and the leading end of the succeeding wipe is left protruding from the package.
• the leading end of the succeeding wipe is immediately and automatically positioned for grasping and subsequent withdrawal from the package, and what was previously the succeeding wipe now becomes the leading wipe.
• a situation in which one or more succeeding wipes are in a single pull operation withdrawn from the package by virtue of being in operative contact with the leading wipe is referred to herein as "multiples.” Multiples can result from excessively strong or geometrically ineffective connections between successive wipes (e.g., too much adhesive or insufficient web perforations), or can result from a dispensing orifice that does not sufficiently hold in place the succeeding wipe to allow the leading wipe to break free (e.g., too large of a dispensing orifice).
• the succeeding wipe after breaking free from the leading wipe, may not be readily accessible for subsequent dispensing.
• the leading end of the succeeding wipe may momentarily protrude from the package as it follows the leading wipe during withdrawal of the leading wipe, the leading end of the succeeding wipe often subsequently falls back through the dispensing orifice into the dispensing container - herein referred to as a "fallback.”
• Fallbacks can result from insufficiently strong or geometrically ineffective connections between successive wipes (e.g., not enough adhesive or an excessively weak line of weakness), or can result from a dispensing orifice that does not sufficiently hold the leading edge of the succeeding wipe in an outwardly protruding manner (e.g., too large of a dispensing orifice).
• the succeeding wipe may entirely fail to exit the package as the leading wipe is withdrawn, such as when the connection between the leading wipe and the succeeding breaks prematurely (i.e.; before the leading wipe is fully withdrawn

• the orifice top edge 82 and the orifice bottom edge 84 may each be a point where the orifice first side edge 81 is joined to the orifice second side edge 83.
• the orifice top edge 82 and the orifice bottom edge 84 may be positioned at the top-most and bottom-most, respectively, points of the orifice 27. That is, the orifice 27 may have a length dimension 85 extending in the longitudinal direction 13 and measured between points having a same longitudinal position as the orifice top edge 82 and the orifice bottom edge 84.
• the length dimension 85 defines both a longest dimension in the longitudinal direction 13 and a largest dimension of the orifice 27.
• the orifice 27 may be taller (in the longitudinal direction 13) than the orifice 27 is wide (in the transverse direction 11).
• the orifice 27 may further comprise a width dimension 87.
• the width dimension 87 may be determined as a greatest dimension of the orifice 26 in the transverse direction 11.
• the greatest transverse dimension of the orifice 27 is located at a mid-point between the orifice top edge 82 and the orifice bottom edge 84 - for example, as defined by middle transverse axis 86.
• the length dimension 85 may be between 44 mm and 60 mm. Lengths of between 44 and 60 mm are advantageous in that they provide a large enough opening in the longitudinal direction 13 through which a user may fit two fingers for grasping an edge of a sheet of product 22, which may be generally oriented in the transverse direction 11, perpendicular to the longitudinal direction 13.
• the width dimension 87 may preferably be between 20 mm and 40 mm, and more preferably between 25 mm and 35 mm. Such width dimensions 87 similarly allow for a comfortable dispensing experience for a user by providing sufficient space for grasping of an edge of a sheet of product 22 disposed within the housing 14. Such width dimensions 87 are also important for providing a desirable pop-up dispensing function with minimal failures, as will be described in more detail below.
• the shape of the orifice first side edge 81 and the orifice second side edge 83 is advantageous for at least one of the orifice first side edge 81 and the orifice second side edge 83 to have a convex shape.
• the orifice first side edge 81 has a bowed- out shape, where the orifice first side edge 81 extends outward from the orifice top edge 82 and the orifice bottom edge 84.
• the orifice second side edge 83 may alternatively comprise a convex shape. Again in the example of FIG.
• the orifice second side edge 83 can be seen having a bowed-out shape with the orifice second side edge 83 extending outward from the orifice top edge 82 and the orifice bottom edge 84 and away from the orifice first side edge 81.
• both of the orifice first side edge 81 and the orifice second side edge 83 may comprise a convex shape, as in the example of FIG. 5.
• the orifice first side edge 81 may extend further away from the orifice top edge 82 and the orifice bottom edge 84 than the orifice second side edge 83. In this manner, the orifice first side edge 81 may have a greater degree of overall curvature than the orifice second side edge 83. As will be described in more detail, it may be desirable for the orifice second side edge 83 to have a relatively flat shape. Thus, in order to provide of the desired width dimension 87 of the orifice 27, the orifice first side edge 81 is required to have a greater degree of curvature than the orifice second side edge 83 in these embodiments.

• the orifice second side edge 83 should have a relatively flat shape, as depicted in FIG. 5.
• a tangent line drawn tangent to any point on the orifice second side edge 83 should form an angle of less than 20 degrees with respect to the longitudinal direction 13.
• angle 91 can be seen forming an angle between the longitudinal direction 13 and an exemplary tangent line 90.
• a tangent line drawn tangent to any point on the orifice second side edge 83 should form an angle of less than 10 degrees, or less than 5 degrees, with respect to the longitudinal direction 13.
• Another aspect of the shape of the orifice 27 is that it may be most important for a central portion of the orifice second side edge 83 to have a relatively flat shape and that may be less important for the portions of the orifice second side edge 83 disposed most closely to the orifice top edge 82 and the orifice bottom edge 84 to have a relatively flat shape. Accordingly, in some embodiments, it is preferred that a tangent line drawn tangent to any point on the orifice second side edge 83 within a central portion 93 forms an angle of less than 20 degrees, or less than 10 degrees, or less than 5 degrees, with respect to the longitudinal direction 13.
• the central portion 93 of the orifice second side edge 83 may be the portion of the orifice second side edge 83 disposed away from the orifice top edge 82 or the orifice bottom edge 84 in the longitudinal direction 13 a distance greater than 5% of the orifice length dimension 85. According to further aspects, the central portion 93 of the orifice second side edge 83 may be the portion of the orifice second side edge 83 disposed away from the orifice top edge 82 or the orifice bottom edge 84 in the longitudinal direction 13 a distance greater than 10%, greater than 15%, or greater than 20% of the orifice length dimension 85.
• a relatively flat shape for the orifice second side edge 83 may be desired, it may also be the case that the orifice second side edge 83 should not be parallel to the longitudinal direction 13. Orifices 27 with such parallel side edges may be difficult to process in a repeatable manner. So, in some contemplated embodiments of the present disclosure, a tangent line drawn tangent to each point on the orifice second side edge 83 may form an angle of greater than 0 degrees with respect to the longitudinal direction 13.
• a tangent line drawn tangent to each point on the orifice second side edge 83 may form an angle of greater than 2 degrees, or greater than 4 degrees, or greater than or equal to 5 degrees with respect to the longitudinal direction 13.

• Another feature of importance of the orifice 27 and the flange 60 to successful dispensing with a low failure rate is a position of the orifice second side edge 83 and the interior wall of the flange 60.
• distance 95 defines a minimum distance between the orifice second side edge 83 and the interior wall of the flange 60, the distance 95 being measured at a midpoint of the orifice in the longitudinal direction 13.
• the interior wall of the flange 60 is shown as defined by the moisture retention ridge 65, but this need not be the case in all embodiments.
• the moisture retention ridge 65 may be disposed outward of the interior wall of the flange 60. Regardless, it may be important in order to achieve successful dispensing with a low failure rate for the distance 95 to be small, such as less than 10 mm, less than 7.5 mm, less than 5 mm, less than 3 mm, or less than 2 mm.
• Such small values for distance 95 ensure that the second side edge 83 of the orifice 27 is disposed close to the interior wall of the flange 60 whereby the rigidity of the flange 60, at least where housing 14 comprises a flexible packaging, can help to ensure consistent separation of the wipes within the stack 22.
• the distance 95 is too large, the wipes being dispensed from the orifice 27 will cause the second side edge 83 to bend and flex to a greater degree resulting in a decreased force on the connected wipes of the stack 22 being dispensed and therefore increasing a rate of ‘multiples' dispensing failures.
• the rigidity of the flange 60 proximate the second side edge 83 helps to prevent the orifice second side edge 83 from bending and flexing, thereby resulting in a relatively increased force on the wipes being dispensed, helping to ensure separation of successive wipes as they are dispensing from the orifice 27.
