Description

A SURTIER BACKGROUND OF THE INVENTION Wet cleaning cloths are available in a variety of shapes, sizes and compositions. A common wet cleaning cloth is a disposable, previously moistened towelette. Such wet cleaning cloths can be used in a variety of both domestic and industrial applications and can perform a variety of functions. Wet wipes are typically used to clean both animate and inanimate surfaces, and can provide numerous benefits such as grooming, cleaning, disinfection, and skin care benefits. A particular application of wet wiping cloths is to clean parts of a human body particularly when washing water is not available, for example when traveling. Wet cleaning cloths are also commonly used for human cleaning and general cleaning such as anal, perineal and genital cleaning, and cleaning of the face and hands. An example of such a wet cleansing cloth is cloth for intimate feminine hygiene. Wet wipes can also be used for the application of substances to the body that include removing or applying make-up, skin conditioners and medications. Other applications for wet cleansing wipes include cleaning a baby's buttocks during diaper changes and for the treatment of adult and baby dermatitis partially caused by the use of diapers and incontinence undergarments. Additionally, wet cleaning cloths can be used to clean or clean other surfaces or for the application of compositions to surfaces. For example, wet cleaning cloths can be used to clean surfaces in the kitchen and bathroom, lenses, shoes and surfaces which require cleaning in industry. Examples of cleaning cloths in industrial applications include cleaning surfaces of tools, machinery, materials and greasy or dirty, contaminated parts, etc. Wet cleaning cloths can also be used for cleaning or grooming pets such as cats and dogs.

Several dispenser designs are commercially available today for storing, storing and dispensing such wet cleaning cloths. Some are long tubes or flexible packages that are several inches in vertical height. Such long jets are designed to hold more than 80 wet cleaning cloths. Other designs include thin travel jets or travel packages and may contain less than 25 wet cleaning cloths. Some dispensers allow for the removal of an individual cleaning cloth while others allow multiple cleaning cloths to be simultaneously removed from the dispenser. One issue with many dispensers is the lack of ease in removing a simple wet cleaning cloth with one hand. For example, a mother in the act of changing an infant's diaper may require using her right hand to keep the baby still while using only her left hand to open and grasp a wet cleaning cloth. Under such conditions, the consumer needs to be able to easily pick up and detach a wet cleaning cloth from a pile and remove wet cleaning cloth from the dispenser using only one hand and without causing the dispenser to be lifted from the surface on which it is placed during the removal process.

The problem of not being able to easily supply a simple wet cleaning cloth from the pile and remove it from the spout is due to a number of reasons. First. Each sheet of wet cleaning cloth is commonly folded twice or folded three times and then placed one on top of the other to form a pile. Many times, the sheets of wet wipes are folded, nested, interlaminated and attached to a sheet of wet wiping cloth adjacent by a perforated torn line. The exact location of the front edge of the topmost sheet in the stack may not be easily identified, either visually or by touch. This is partly due to the fact that the substrate material of the wet cleaning cloth is typically homogeneous and therefore the front edge of the wet cleaning cloth, particularly when folded, can be difficult to distinguish from the substrate material on which it rests.

Additionally, the front edge portion of the wet cleaning cloth has a tendency to adhere to the underlying cleaning cloth substrate material on which it rests. Therefore, even the tactile identification of the edge by running or dragging the fingers through the surface of the wet cleaning cloth immediately does not result in the identification of the location of the edge.

A second problem is that once the front edge is located, it can be difficult for the consumer to grab enough substrate material and maintain a grip of the substrate in order to separate a sheet of simple wet cleaning cloth from the pile in which it rests. . The consumer is often only able to grip a small part of the front edge such that a strong grip of it is not established and therefore the wet cleaning cloth sheet slides easily from the consumer's fingers.

Other factors contributing to the problem of providing a simple wet cleaning cloth include the tendency of the wet cleaning cloth substrate material to adhere to itself. This is partly due to the compression of the pile of wet cleaning cloths during manufacturing and storage. The existence of an attractive force between the sheets of adjacent wet cleaning cloths is composed of the liquid solution used to impregnate the substrate material. Wet materials tend to adhere to themselves. Additionally, the actual pile weight of the wet cleaning cloths tends to hold them together. As a result, when the wet cleaning cloths are folded or interlaminated together to form a pile, the substrate material tends to adhere also to the substrate material of the adjacent sheets. Additionally, when the wet cleaning cloth is interlaminated or joined together by a tear line, such as a perforation line, the additional strength is created since a force is necessary to overcome the connection between the sheets of adjacent wet cleaning cloths.

A spout has now been invented which will facilitate the separation of a simple wet cleaning cloth from the pile and the removal of a simple wet cleaning cloth from the dispenser without facing the previously identified problems.

SYNTHESIS OF THE INVENTION Briefly, this invention relates to a dispenser which can store a plurality of folded wet wipes, each having a width. The spout includes first and second members pivotally connected together to form an enclosed spout having a transverse axis. The first and second members are formed of a semi-rigid material. The spout has a height of about 2.5 inches or less and has a top wall with an inlet formed therein. The entrance has a surface area of between about 15 square centimeters to about 95 square centimeters. The bent wet cleaning cloths have a normalized separation force between two adjacent wet cleaning cloths of less than about 65 grams per centimeter. The inlet also has a dimension, measured along the transverse axis, which when divided by the width of one of the folded wet cleaning cloths is at least about 0.7.

DETAILED DESCRIPTION Referring to Figures 1 and 2, a dispenser 10 is shown which is capable of storing, storing and supplying a plurality of sheets of wet cleaning cloths 12, of 2 locations. The spout 10 has a generally rectangular configuration, a longitudinal central axis X-X, a transverse central axis Y-Y and a vertical axis Z-Z. The spout 10 also has a total length L, a width w and a height h. The dimensions of the dispenser 10 may vary to accommodate the particular needs of one. The total size of the dispenser 10 can be selected to be thin enough to easily fit in a woman's bag, in a diaper bag, in a glove compartment of a car, in a desk drawer, etc. The spout 10 can also fit in an elongated bag of a coat. The spout 10 can be reused and is capable of being refilled multiple times during its life. For the spout 10, the dimensions can be in the range of from about 6 inches (about 15 centimeters (cm)) to about 12 inches (about 30 centimeters) in a total length L, of between about 3 inches (about 7.6 centimeters) to about 6 inches (about 15 centimeters) in width w, and has a height h equal to or less than about 2.5 inches (about 6.4 centimeters). More desirably, the spout 10 can range from about 7 inches (about 18 centimeters) to about 10 inches (about 25 centimeters) in total length L, of about 3.5 inches (about 8.9 centimeters) up to about 5 inches (about 12.7 centimeters) in width w, and has a height h equal to or less than about 2 inches (about 5 centimeters). More desirably, the spout 10 may have a height h equal to or less than about 1.5 inches (about 3.8 centimeters). Even more desirably, the spout 10 may have a height h equal to or less than about 1 inch (about 2.5 centimeters).

The spout 10 is designed to store and store a plurality of wet cleaning cloths 12 in a water-resistant environment. The dispenser 10 may allow the cleaning cloths 12 to retain their moisture until the user is ready to remove and use the wet cleaning cloths 12. The wet cleaning cloths 12 may be removed from the dispenser 10 either individually or as a group of two. or more .

Referring to Figure 3, a simple wet wiping cloth 12 is shown to have a longitudinal central axis Xi-Xi, a transverse central axis Yi-Yi, and a vertical axis Zi-Z ^ .. By a "wet wiping cloth" means a relatively flat sheet that is wet or damp to the touch and is impregnated with a liquid solution. A damp cleaning cloth may include a pre-dampened sheet, a previously moistened facial tissue, a wet towel, a wet towel, an impregnated sheet, a hand wipe, a cleaning cloth for baby, etc. Each wet cleaning cloth 12 can have any desired geometric cross section configuration. Desirably, each wet cleaning cloth 12 can have either a square or rectangular cross section shape. The wet cleaning cloth 12 has a length i, a width x and a thickness ti. The dimensions of length Li, wif width and thickness may vary depending on one's particular needs and desires. The dimensions of length Li and width wx each can range from about 5 inches (about 12.7 centimeters (cm)) to about 10 inches (about 25.4 centimeters). Desirably, the dimensions of the length L and the width wa each may range from about 6 inches (about 15.2 centimeters) to about 9 inches (about 23 centimeters). More desirably, the dimensions of length Li and width x each may range from about 7 inches (about 17.8 centimeters) to about 9 inches (about 20.3 centimeters). The thickness dimension ti can usually be in the range of between about 0.4 millimeters (mm) to about 5 millimeters. Desirably, each cleaning cloth 12 may have a thickness tx that is in the range of between about 0.5 millimeters to about 3.5 millimeters. More desirably, each wet cleaning cloth 12 may have a thickness tx that is in the range of between about 0.6 millimeters to about 3 millimeters. For example, a commercially available wet cleaning cloth has a length Lx of about 7.5 inches (about 19 centimeters), a width wl of about 7.5 inches (about 19 centimeters) a thickness tx of less than about 1 millimeter, when it is in an unfolded state.

In this wet cleaning cloth product, the dimensions of length A and width x are the same; however, these do not have to be the same for the purposes of this invention.

Each wet cleaning cloth 12 consists of a substrate that is impregnated as a liquid solution. The substrate can be produced by any method known to those skilled in the art. For example, nonwoven substrates can be formed by dry forming techniques such as laying with air or wet laying such as in a paper making machine. Other nonwoven manufacturing techniques such as air laying, meltblowing, bonded bonding, needle punching and spinning methods can also be used. The hydroentanglement is a method that can also be used.

The substrate can be formed of one or more layers and one or more materials. When more than one layer is used, the layers may be identical in terms of composition or manufacturing techniques or consist of a combination of different materials. A good material from which the substrate can be formed the coform. The coform is a composite material containing meltblown microfibers and cellulose fibers (wood). A desirable blend includes about 5% to about 95% polypropylene and about 95% to about 5% cellulose fibers. The coform is commercially produced by Kimberly-Clark Corporation which has an office at 401 North Lake Street, Neenah, Wisconsin 54956.

The substrate material is typically impregnated coated with a liquid composition. In accordance with this invention, the term "liquid composition" refers to any composition which is in a liquid form when it contacts the substrate. Typically, the composition may be aqueous, alcohol-based or an emulsion, either a water-in-oil or an oil-in-water or multiple emulsion. The emulsion may also contain a lipid phase which can be broken by applying minimal pressure, for example, by cleansing the skin. The composition may contain from about 50% to about 98% by weight of water, desirably deionized or distilled water, and from about 2% to about 50% by weight of active ingredients. Desirably, the liquid composition may contain at least 97% water. Of the active components, appreciably around 2% up to about 20% are present in the oil phase and the remainder are present in the aqueous phase.

The composition may include a preservative or a stability agent. Stability agents suitable for use herein include phenoxyethanol desirably in the range of from about 0.1% to about 1.0%, sodium benzoate, potassium sorbate, methylparaben, propylparaben, ethylparaben, butylparaben, sodium benzoate, potassium sorbate. , benzalkonium chloride, and ethylenediamine tetraacetic acid (EDTA) and other EDTA salts (sequesters). Sequestrian is a series of complex and complex metal agents, usually salts and ethylenediamine tetraacetic acid. The total amount of stabilizing agents should be in the range of about 0.1% to about 4.0% by weight of the composition.

The composition of the present invention may additionally include from about 0.02% to about 5.0% by weight of an emollient or humectant. Desirably, the emollient is water soluble and includes polyhydric alcohols, such as propylene glycol, glycerin, and also water soluble lanolin derivatives.

Additional optional ingredients which may be used in the composition include: anti-fungicidal agent, antibacterial agents, skin protectants, oil-soluble cleaning agents, water soluble detergents, surfactants or detergent, desirable non-ionic or amphoteric, pH adjusters, perfumes, fragrances and the like.

In preparing the wet cleaning cloth 12, the liquid composition is applied to at least one surface of the substrate material. The liquid composition can be applied at any time during the manufacture of the wet cleaning cloth 12. Desirably, the liquid composition can be applied to the substrate after the substrate has been dried. Any variety of application methods that can evenly distribute lubricating materials that have a molten or liquid consistency can be used. Appropriate methods include spraying, printing, (for example, flexographic printing), coating (e.g., etched coating or flood coating), extrusion whereby the composition is forced through tubes in contact with the substrate while the substrate passes through the tube, or combinations of the prior techniques.

The liquid composition may also be non-uniformly applied to one or more surfaces of the substrate. By "non-uniformly" it means that the amount and / or pattern of distribution of the liquid composition may vary over the surface (s) of the substrate. For example, something of a surface of the substrate may have a greater or lesser amount of the liquid composition, which include the parts of the surface that have no composition therein.

Referring now to Figure 4, a plurality of wet wipers 12 folded are shown arranged in a stack 14. "Stack" means an amount, a heap, an array or group of three or more wet wipers 12. Each stack 14 it may include an orderly arrangement and may include up to eighty (80) or more wet wipers 12. Desirably, each stack 14 may contain from eight (8) to about fifty (50) wet wipers 12. More desirably, each stack 14 may contain from about eight stench (8) to about forty (40) wet cleaning wipes 12. More desirably, each stack 14 may contain up to sixteen (16) wet cleaning wipes 12. Typically, each of the wet wiping cloths 12 is folded either before or during the process of being arranged in the stack 14. In Figure 4, each of the wet cleaning cloths 12 is bent into J and arranged one on top of the or with the stepped J fold to form a stack of approximately uniform height h.2. The height h.2 of the stack is less than the height h of the spout 10.

The stack 14 has a longitudinal central axis X2-X2, a transverse central axis Y2-Y2 and a vertical axis Z2-Z2. In the stack 14, each of the wet cleaning cloths 12 has a length L2, a width w2 and a height h2. The length L2 is shown as being equal to the initial length Lx of the simple wet cleaning cloth 12 shown in Figure 3. However, if desired, each of the wet cleaning cloths 12 can be folded longitudinally. The width w2 of the wet cleaning cloth 12 folded is less than the width w2 without initial bending. Normally, the folded width w2 is between about 10% up to about 50% less than the initial width wx. The current width w2 of each of the folded wet wipes 12 can be in the range from about 1 inch (about 2.5 centimeters) to about 5 inches (about 12.7 centimeters). More desirably, the width w2 of each of the folded wet wipes 12 may be in the range from about 2 inches (about 5 centimeters) to about 4 inches (about 10 centimeters). More desirably, the width w2 of each of the folded wet wipers 12 may be about 3.75 inches (about 9.5 centimeters).

Each of the wet wipers 12 has a front or top edge 16 and a rear or bottom edge 18. The front or top edge 16 is designed to be easily grasped or snatched by reaching it at the spout 10 with one or more fingers and the thumb. The front or upper edge 16 can be located along the longitudinal central axis X2-X2 of the stack 14 or is located on either side thereof. It is also advantageous that the front or top edge 16 is visibly apparent. To assist in making the front edge 16 more visually apparent, it may be formed to have a non-linear configuration. For example, a shell-shaped design is shown in Figure 4. The shell edge 16 consists of a series of semicircular curved projections that form an ornamental border. The shell design makes the upper edge 16 more visible to the ultimate consumer and the shell design also helps in allowing the user to grip the wet cleaning cloth 12. Other non-linear profiles can also be used.

It should also be noted that the front or top edge 16 of each of the wet wipers 12 can be colored or have a color printed thereon to make the edge 16 more visually apparent to the consumer. Other means known to those skilled in the art may also be utilized to make the front edge 16 more visual.

Referring now to Figure 5, another configuration of a stack 20 of a plurality of wet cleaning cloths 12 is shown. The word "stack" has been previously defined. In the stack 20, each of the wet cleaning cloths 12 is bent into Z and interlaminated together to thereby form an approximately uniform pile height h3. The height h3 of the stack is less than the height h of the spout 10.

The stack 20 has a longitudinal central axis X3-X3, a transverse central axis Y3-Y3 and a vertical axis Z3-Z3. On the stack , each of the wet cleaning cloths 12 has a length L3, a width w3 and a height h3. The length L3 is shown as being equal to the initial length Li of the simple wet cleaning cloth 12 shown in Figure 3. However, each of the wet cleaning cloths 12 can be longitudinally coupled, if desired. The width w3 is less than the width wa without initial bending. Normally, the folded w3 width is from about 10% to about 50% less than the initial wx width. The current w3 width of each of the folded wet wipes 12 can be in the range of between about 1 inch (about 2.5 centimeters) to about 5 inches (about 12.7 centimeters). More desirably, the width w3 each of the folded wet wipes 12 may be in the range of from about 2 inches (about 5 centimeters) to about 4 inches (about 10 centimeters). More desirably, the width w3 of each of the folded wet wipers 12 may be about 3.75 inches (about 9.5 centimeters).

Each of the wet wipers 12 has a front or top edge 22 and a rear or bottom edge 24. The front or top edge 22 is designed to be easily grasped or snatched by reaching it from the spout 10 with one or more fingers and thumb . The front or upper edge 22 can be located along the longitudinal central axis X2-X2 of the stack 20 or is located on any edge of the same. It is also advantageous that the upper front edge 2 is visibly evident. To assist in making the front edge 22 more visually apparent, it may be formed as a linear line but may be angled relative to the longitudinal central axis X3-X3 of the stack 20, if desired. The stack 20 also includes an ordered array of the wet cleaning cloths 12, and was previously explained with reference to the stack 14. The number of wet cleaning cloths 12 making the stack 20 can also be of the aforementioned amount.

It should be noted that each of the wet cleaning cloths 12 in the stack 20 is interlaminated or sandwiched between a portion of a wet cleaning cloth 12 adjacent to that of the more upper wet cleaning cloth sheet 12 is removed from the stack 20, the subsequent damp wiper cloth 12 may be exposed and have its upper edge 22 available to be grasped or snatched away.

It should be noted that the wet cleaning cloths 12 can be constructed of an absorbent or a non-absorbent material. By "absorbent" it means that each of the wet cleaning cloths 12 is capable of absorbing a liquid, a chemical solution, a non-solid substance, etc. An example of a liquid is water, an example of a chemical solution is a mouthwash, and an example of a non-solid substance is a cosmetic cream. The wet cleaning cloths 12 may be oriented in the spout 10 in a relatively flat arrangement or be bent in some way. The longitudinal axis X2-X2 or X3-X3 of the wet wipers 12 folded should be aligned essentially parallel to the longitudinal axis XX of the spout 10, see figure 1. This orientation may facilitate the removal of the wet cleaning cloths 12 from the spout 10. Common forms for populating wet wiping cloths 12 include, but are not limited to, C-folds, J-folds, Z-folds, etc.

The wet cleaning cloths 12 may be formed of synthetic or natural fibers or a combination of such fibers. Cotton fibers and wood pulp are two examples of natural fibers. Synthetic fibers can include polyolefin fibers, such as polypropylene and polyethylene fibers. The wet cleaning cloths 12 can be moistened with an aqueous composition which contains among other things, surfactants, preservatives, lotions, solutions, oils, medicines, essences, fragrances, etc. or any combination thereof. An example of a wet cleaning cloth for babies is the ORIGINAL HUGGIES which is a registered trademark of Kimberly-Clark Corporation which has an office at 401 North Lake Street Neenah, Wisconsin 54956. This wet cleaning cloth contains water, laureth phosphate potassium, glycerin, polysorbate 20, ethylenediamine tetrasodium tetraacetic acid, DMDM hydantoin, methylparaben, malic acid and a fragrance. The wet cleaning cloths 12 are typically packed in the dispenser 10 to facilitate the easy storage, transport and recovery of the wet cleaning cloths 12 for various uses.

The spout 10 is unique in that it allows the wet cleaning cloths 12 to be removed or removed either individually or as a group of two or more items. One or more of the wet cleaning cloths 12 can be removed through a first entry by reaching them in the spout 10 or a wet cleaning cloth 12 can be removed through a second inlet in an emergence manner. This will be explained in more detail below. The dispenser 10 can be manufactured in various sizes and shapes and can be constructed from a variety of materials. The spout 10 can be constructed of a relatively semi-rigid or rigid material. By "semi-rigid or rigid" it means a material that can maintain its total form and can not substantially deform when it is normally manipulated for its intended purpose. A "semi-rigid or rigid" material has a thickness of at least about twenty thousandths (.020) of an inch. Desirably, a semi or rigid material may have a thickness equal to or greater than about thirty thousandths (.030) of an inch. More desirably, a semi or rigid material may have a thickness equal to or greater than about forty thousandths (.040) of an inch. The spout 10 can be formed of almost any type of material. A desirable material from which the spout 10 can be formed is a thermoplastic material. The thermoplastic can be a polyolefin such as polypropylene, polyethylene, polystyrene, acrylonitrile butadiene styrene, polyester, polyvinyl chloride, polycarbonate, high density polyethylene, or a copolymer formed thereof. Other types of thermoplastics can also be used. Desirably, the spout 10 is formed of polypropylene. The spout 10 can also be formed of ferrous and non-ferrous metals, metal alloys, aluminum, wood, plywood, veneer, thick cardboard, a laminate of different types of plastics, a combination of laminates of plastic and paper, of laminates of plastic film, of thermoplastic strips inserted in a laminate, or a combination thereof. Additionally, other types of semi-rigid materials known to those skilled in the art can also be used.

It should be noted that very flexible materials having a thickness of less than about 0.4 millimeters are not interpreted as being a "rigid semi-rigid" material. A flexible wrapping material such as aluminum foil, thin plastic films, very thin laminates, paper bags, etc. They are not considered to be semi-rigid materials.

Desirably, the spout 10 is formed of a thermoplastic material that can be injection molded. Normally, the molded material with injection may have a thickness in the range of between about 0.5 millimeters to about 6 millimeters. More desirably, the injection molded material may have a thickness in the range of from about 0.5 millimeters to about 5 millimeters. More desirably, the molded material with infection may have a thickness in the range from about 0.75 millimeters to about 2 millimeters.

Referring again to Figures 1 and 2, the spout 10 includes a first member 26 and a second member 28. The first and second members, 26 and 28 respectively, are hollow members having a depth dimension and each having a surface or open wall. Each of the first and second members, 26 and 28 respectively, and is capable of maintaining or retaining a quantity of wet cleaning cloths 12. Each of the first and second members, 26 and 28 respectively, has a thickness of less about twenty thousandths (.020) of an inch. The first and second members, 26 and 28 respectively, are pivotally connected by a hinge 30. As previously mentioned, the first and second members, 26 and 28 respectively, can be formed by injection molding. By injection molding the first and second members, 26 and 28 respectively, together, they can be integrally formed as a single entity. The hinge 30 can also be injection molded together with the first and second members, 26 and 28 respectively. The hinge 30 can be a living hinge. By a "living hinge" it means a hinge that is integrally formed with and constructed of the same material as was used to form the first and second members, 26 and 28 respectively. Usually, a living hinge has a smaller thickness relative to the total thickness of the two members to which it is connected.

As shown in Figure 1, the spout 10 is described as a thin travel pack that can be initially filled with a plurality of wet wipers 12. The spout 10 has a height "h" which can be equal to or less than about 2.5 inches (around 6. 4 centimeters). Desirably, the height "h" of the dispenser 10 may be in the range between about 0.5 inches (about 1.3 centimeters) to about 2 inches (about 5 centimeters). More desirably, the spout 10 has a height "h" of about 1.5 inches (about 3.8 centimeters). Even more desirably, the spout 10 may have a height "h" of about 1 inch (about 2. 5 centimeters). As previously explained, the wet cleaning cloths 12 can be stacked in the spout 10 in an interlaminate or non-interlaminate arrangement. In either case, the upper edge 16 or 22 of each wet cleaning cloth 12 should extend longitudinally, essentially parallel to the longitudinal central axis X-X of the spout 10.

Still referring again to Figures 1 and 2, the first and second members, 26 and 28 respectively, are hinged together and can pivot or rotate between a closed position, shown in Figures 1 and 2, and an open position, not shown When the second member 28 is pivoted in the hinge 30 to an open position, the first entry 32, the location of which is indicated by the front line and the arrow extending from the number 32, is formed in the spout 10. When the second member 28 is thus pivoted by at least 90 ° relative to the first member 26, the first inlet 32 may be equal to or larger than the entire upper surface of the exposed stack 20 of cleaning cloths The length L3 and the width w3 of the stack 20 of the wet cleaning cloths 12 is less than the total length L and the width w of the dispenser 10. This difference in size is important since it allows the consumer to easily reach with his or her hand and grab or snatch as many of the damp cleansing cloths 12 as he or she wants. It should be readily apparent to the reader that the first inlet 32 allows one or more of the wet wipers 12 to be removed by removal in a simple time. In fact, the entire stack 20 of wet cleaning cloths 12 may be removed when the user at a time, if desired.

Continuing referring to Figures 1 and 2, the second member 28 of the spout 10 includes an upper wall 34 having an entrance 36 formed therein. The inlet 36 may be referred to as the second inlet to distinguish it from the first inlet 32. The second inlet 36 is shown as an opening formed completely through the upper wall 34. Desirably, the upper wall 34 is a flat surface which is vertically oriented relative to the upper surface of the stack 20 of the wet cleaning cloths 12. The second entry 36 has a surface area that can range from about 15 square centimeters to about 95 square centimeters. Desirably, the second inlet 36 has a surface area that can range from about 15 square centimeters to about 70 square centimeters. More desirably, the second inlet 36 has a surface area that can range from about 20 square centimeters to about 50 square centimeters. More desirably, the second inlet 36 has a surface area that can range from about 20 square centimeters to about 40 square centimeters.

The second inlet 36 is described as being aligned along both longitudinal and transverse axes, XX and YY respectively, of the spout 10. In fact, the intersection of the longitudinal and transverse axes, XX and YY respectively, forms the center of the second entry 36. It should be noted that the second entry 36 may be offset from the longitudinal and transverse axes, XX and YY respectively, if desired. The second inlet 36 is shown as being elliptical or oval in configuration, although other geometric configurations may also be used. Examples of various profiles for the second inlet 36 include but are not limited to: a round or circular opening, a semicircular opening, a square opening, a rectangular opening, etc. The second inlet 36 of elliptical shape has a length L4 measured along its major axis and a width w measured along its minor axis. The length L4 of the second inlet 36 is shown aligned approximately parallel to the transverse center axis YY of the spout 10. In the same manner, the width w4 of the second inlet 36 is shown aligned approximately parallel to the longitudinal central axis XX of the spout 10. Other Orientations are also possible. For example, the longest dimension of the second inlet 36 may be aligned approximately parallel to the transverse axis Y-Y of the spout 10, approximately perpendicular to the transverse axis Y-Y of the spout 10, or be aligned at an angle to the transverse axis Y-Y of the spout 10.

The dimensions of the second inlet 36 should be selected to ensure that the wet wipers 12 can be individually removed from the spout 10. The second inlet 36 should have a transverse dimension, measured parallel to the transverse axis YY, (which is the length L4 of the orientation shown in Figures 1 and 2) which is at least about 60% of the width w of the spout 10. For example, if the width w of the spout is 10.5 centimeters, then the transverse dimension, measured parallel to the transverse axis YY, of the second inlet 36 should be at least about 6.3 centimeters. Another way of describing the dimension of the second inlet 36 when measured parallel to the transverse axis Y-Y, is to compare it with the width w2 or w3 of the wet wipers 12 folded. Desirably, the second inlet 36 has a dimension (the length L of the orientation shown in Figures 1 and 2) which is in the range of between about 60% to 150% of the width w2 or w3 of the wet wipers 12 bent More desirably, the second entry 36 has a dimension, when measured parallel to the transverse axis Y-Y and, which is in the range of between about 70% to 100% of the width w2 or w3 of the wet cleaning cloths 12 folded. More desirably, the second inlet 36 has a dimension, when measured parallel to the transverse axis Y-Y, which is in the range of between about 75% to 95% of the width w2 or w3 of the wet wipers 12 folded. For example, if the wet cloths 12 folded a width of about 3.5 inches (about 3.5 centimeters), then the second entry 36 should a dimension, measured parallel to the transverse axis YY, of at least about 2.1 inches. (about 5.3 centimeters).

In addition, the second inlet 36 must have a dimension measured along the longitudinal axis X-X (the width w4 for the orientation shown in Figures 1 and 2) which is at least about 1.9 centimeters in order to accommodate the width of the thumb and index finger of the user. Desirably, the second inlet 36 has a dimension measured along the longitudinal axis X-X ranging from between about 1.9 centimeters to about 100% of the length of L2 or L2 of the folded wet cleaning cloth 12. More desirably , the second inlet 36 has a dimension measured along the longitudinal axis X-X which varies from between about 2.5 centimeters to about 80% of the length L2 p L3 of the folded wet cleaning cloth 12. Even more desirably , the second inlet 36 has a dimension measured along the longitudinal axis X-X which varies from between about 2.5 centimeters to about 70% of the length L2 or L3 of the folded wet cleaning cloth 12. More desirably, the second inlet 36 has a dimension measured along the longitudinal axis X-X which varies from between about 2.5 centimeters to about 30% of the length L2 or L3 of the wet cleaning cloth folded 12. In t In terms of the actual dimensions, as measured along the longitudinal axis X-X, the second inlet 36 may vary from about 0.75 inches to about 7.5 inches (about 19 centimeters) for a folded wet cleaning cloth 12 which has a global length L2 or L3 of about 7.5 inches (about 19 centimeters). Another example will be a second inlet 36 having a dimension measured along the longitudinal axis X-X, which varies from about 2.5 centimeters to about 5.7 centimeters for a folded wet cleaning cloth 12 having an overall length L2 or L3 of about 19 centimeters.

Referring to figure 6, the second entry 36 is shown aligned at an angle with respect to the transverse Y-Y axis. From this embodiment, one can pull two lines which intersect tangentially the opposite ends of the second inlet -36 and these can be extended to intersect perpendicularly the transverse axis Y-Y. The dimension L5 located between these two lines on the transverse axis Y-Y can vary from between about 60% of the width w of the spout 10. For example, the width w of the spout is 10.5 centimeters, then the dimension L5, of the second entry 36 must be at least about 6.3 centimeters. Another way of describing the dimension Ls of the second inlet 36 is to compare this to the width w2 or w3 of the folded wet wipers 12. Desirably, the second inlet 36 has a dimension L5 which varies from about between about 60% at 150% of the width w2 or w3 of the folded wet wipers 12. More desirably, the second inlet 36 has a dimension L5 which varies from about 70% to 100% of the width w2 or w3 of the wet wipers 12. More desirably, the second inlet 36 has a dimension L5 which varies from about 75% to 95% of the width w2 or w3 of the folded wet cleaning cloths 12. For example, the wet cleaning cloths folded 12 they have a width of about 8.9 centimeters, then the second entry 36 must have an L5 dimension of at least about 5.3 centimeters.

Still referring to Fig. 6, when the second inlet 36 is aligned at an angle to the transverse axis Y-Y, one can pull two lines which tangentially intersect the opposite ends of the second inlet 36 and these can extend perpendicularly to intersect the longitudinal axis X - X. The dimension w5 located between these two lines on the longitudinal axis X-X may vary from between about 1.9 centimeters to about 100% of the length L2 or L3 of the folded wet cleaning cloth 12. More desirably, the second inlet 36 has a dimension w5 which varies from between about 2.5 centimeters to about 80 to 100% of the length L2 or L3 of the folded wet cleaning cloth 12. Even more desirably, the second inlet 36 has a dimension w5 which varies from about 2.5 centimeters to about 60% of the length L or L3 of the folded wet cleaning cloth 12. More desirably, the second entry 36 has a dimension ws which varies from between about 2.5 centimeters at about 30% of the length L2 or L3 of the folded wet cleaning cloth 12. In terms of actual dimensions, the dimension w5 which can vary from between about 0.75 inches to about 7.5 inches (about 19 centimeters) for a wet bent wiper cloth 12 having an overall length L2 or L3 of about 19 centimeters. Another example would be a second entry 36 having a dimension w5 which varies from between about 2.5 centimeters to about 5.7 centimeters for the folded wet cleaning cloth 12 having an overall length L2 or L3 of about 19 centimeters.

Still referring to Figures 1 and 2, the spout 10 further includes a third member 38 which is secured to the second member 28 by a hinge 40. The hinge 40 is shown as being spaced apart and aligned parallel to the hinge 30. Yes If desired, the two hinges 30 and 40 can be aligned coaxially one in relation to the other. The third member 38 is able to pivot on the hinge 40 to move it from a closed position as shown in Figures 1 and 2, to an open position, not shown. In the closed position, the third member 38 completely covers or closes the second inlet 36. The third member 38 can be pivoted or rotated back away from the second inlet 36 through an angle of more than 90 degrees to a position where the second 96 entry is completely open. In this orientation, the user can easily insert his index finger and thumb into the second inlet 36 and grasp the upper edge 22 of the wet wiping cloths 12. The uppermost wiping cloth 12 can then be individually removed through the second inlet. 36 and be removed from the spout 10.

The third member 38 can be of almost any geometrical configuration but is shown as having an elliptical or oval shape to conveniently nest on the second inlet 36. The upper wall 34 of the second member 28 can be recessed in the area where the third member 38 will close over the second inlet 36. The third member 38 has an outer or upper surface 42 and an inner or lower surface 44, see Figure 2. The outer surface 42 of the third member 38 can be matched with the upper wall 34 of the second member 28 when in a closed position if desired. The third member 38 also contains a shoulder 46 projecting downward from the inner surface 44 and engaging the inner periphery 48 of the second inlet 36 when the third member 38 is in its closed position. This engagement of the shoulder 46 with the inner periphery 48 forms a tight or interference fit with the second inlet 36 such as an interference or tight fit that will secure the third member 38 to the second member 28 and ensure that the seal is formed around the second entry 36. This seal establishes a barrier to moisture and height to prevent the liquid solution that was used to impregnate the wet cleaning cloths 12 from escaping or evaporating.

The third member 38 may also contain a locking mechanism, not shown, to secure the third member 38 in a closed position on the second inlet 36. An example of a locking mechanism may be an appendix and a latch located between the second member 28 and the interior of the lower surface 44 of the third member 38. As the latch passes over the appendix, it will secure the second and third members 28 and 38 respectively together.

The elliptical or oval shape of the third member 38 also serves another useful function in that it is large enough to allow the user of the dispenser 10 to employ the third member 38 to hold the stationary dispenser 10. The third member 38 is capable of pivoting or rotating at least about 180 degrees from its closed position. Desirably, the third member 38 can pivot or rotate at least about 225 degrees of closed position, and more desirably, at least about 270 degrees of its closed position. For example, the user may place his elbow, knee or other part of the body on the third member 38, when in an open position, having pivoted about 180 degrees from its closed position, to hold the stationary jet 10 while being removed. one or more of the wet wipers 12. It should be mentioned that if the spout 10 is placed on the edge of a table, the third member 38 can be opened from about 225 degrees to about 270 degrees from the closed position and the user can place his hip or thigh against the third member 38 to hold the stationary dispenser 10. furtherWhen the third member 38 is open to about 180 degrees from its closed position, the consumer can place a diaper bag, a bag or any other heavy object on top of it to keep the dispenser stationary. This ability to use the third member 38 to hold or maintain the stationary dispenser 10 without using one's hands is very beneficial.

Still referring to Figures 1 and 2, the spout 10 also has an easy opening mechanism that can be activated with only one hand. This characteristic of opening with one hand is obtained by forming a pair of spaced apart finger tabs 50 and 52 on the first member 26. The pair of finger tabs 50 and 52 is positioned along a side wall 54 of the finger. first member 26 which is aligned opposite the location of hinge 30. The pair of finger appendages 50 and 52 project outwardly from side wall 54 for at least about 0.6 centimeters. Another finger tab 56 is formed on the side wall 58 of the second member 28. The side wall 58 is also aligned opposite the location of the hinge 30. The finger tab 56 projects outwardly from the side wall 58 at least by about 0.6 centimeters. The finger appendage 56 is positioned between or in the middle of the pair of finger appendages 50 and 52. The finger appendage 56 can slightly overlap the lower pair of finger appendages 50 and 52, if desired. The finger appendage 56 is spaced vertically slightly above the pair of finger appendages 50 and 52. In order to open the first inlet 32 inside the spout 10, the consumer requires only pressing down on one of the two appendices. finger 50 or 52 with your thumb and press up with your index finger on the middle finger appendix 56. This action will cause the second member 28 to pivot open in relation to the first member 26.

It should be noted that, alternatively, the pair of finger appendages 50 and 52 can be formed on the second member 28 and the single finger appendage 56 can be formed on the first member 26 if desired. The finger appendages 50, 52 and 56 project outwardly from the side walls 54 and 58 respectively, and provide easy means for the user to open the first inlet 32 inside the spout 10.

In order to facilitate the separation of a single wet cleaning cloth 12 from the stack 20 and to allow easy removal of the single wet cleaning cloth 12 from the dispenser 10, it is beneficial to establish a normalized separation force between the sheets of adjacent wet cleaning cloths 12. This normalized separation force can be obtained by using the test method recited below. It has been found that when the normalized separation force between the adjacent wet cleaning cloths 12 is less than about 65 g / cm, the individual removal of the cleaning cloths 12 can be repeatedly obtained. Desirably, the normalized separation force between the adjacent wet cleaning wipes 12 should vary from between about 0.25 grams / centimeter to about 65 grams / centimeter grams. More desirably, the normalized separation force between the adjacent wet cleaning wipes 12 should vary from between about 0.5 grams / centimeter to about 65 grams / centimeter grams. More desirably, the normalized separation force between the adjacent wet cleaning wipes 12 should vary from between about 0.75 g / centimeter to about 65 g / centimeter grams.

Normalized Separation Force Test Method This test method measures the normalized separation force required to separate two adjacent sheets of wet cleaning cloths in a cutting mode. The test results depend on the nature of the substrate, the liquid composition of the solution used to saturate each wet cleaning cloth, the folding design of each wet cleaning cloth, and the fastening method if there is one, to join two cleaning cloths wet adjacent.

Measurement of the Normalized Separation Force 1. A spout containing a stack of wet cleaning cloths, each in the form of a folded sheet having a width, is obtained directly from an assembly line, from a retail outlet or from any other means. The dispenser, which is usually sealed, is open so that the battery is exposed. 2. The two (2) wet cleaning cloths are carefully removed from the pile without interrupting any folds or tearing lines if present. The two wet cleaning cloths will be gripped between a pair of jaws of a conventional Sintech test machine (model 1-G) equipped with TestWorks 3.10 software for Windows. Both the Sintech test machine and the TestWorks software are commercially available from MTS Corporation having an office at 1400 Technology Drive, Eden Prairie, Minnesota, 55344-2290. The two jaws are initially placed around a separation of 5.0 centimeters, 3. The front end of the first cleaning cloth and the tail end of the second cleaning cloth are carefully unfolded for about 2.5 centimeters across the full width of the wet cleaning cloths.

. The central part of the front end of the first wet cleaning cloth, (about 7.5 centimeters by 2.5 centimeters), is grasped in the upper jaw while the middle part of the tail end of the second wet cleaning cloth, of about 7.5 centimeters by 2.5 centimeters grabs the lower jaw.

. The test machine is activated to move the upper jaw (moving jaw) out of the lower jaw (stationary jaw) at a rate of about 200 centimeters per minute until the two wet cleansing wipes are completely separated. 6. The force in grams (g) as a function of the distance at which the moving jaw has moved in centimeters (cm) is recorded using a TestWorks 3.10 software. The peak load exhibited during the test is designed as the separation force for the two wet cleaning cloths. This force value is then normalized as force per unit length (g / cm) by dividing the force by the length of each of the two wet wipers. For example, if the length of each wet cleaning cloth is around 7.5 centimeters, the normalized separation force equals the force divided by 19 centimeters.

It should be noted that the two wet wipers are joined together by a tearing line that can be broken such as a perforation line or some other fastening mechanism, such as one or more points of adhesive, one or more lines of adhesive, etc., and that this is in addition to the adhesion caused by the liquid composition of the solution used to impregnate the wet wiping cloths 12 that the two peak loads will be evident on the recorded chart. The highest peak load exhibited during the test will be one designated as the separation force for the two wet cleaning cloths.

Finally, it has been found that the smallest dimension (the width w4 for the orientation shown in figures and 2) of the second inlet 36 must be of a sufficient size to allow the consumer to easily insert at least his thumb and forefinger through it and grasping and removing a wet cleaning cloth 12 regardless of the height of the stack 14 or 20 and regardless of the location of the front edge 16 or 22. When the cleaning cloths 12 are removed from the spout 10, the height h2 or h3 of the stack, 14 or 20, respectively, will become shorter and the uppermost wet cleaning cloth 12 will be located further away from the second inlet 36. A relationship which has been found between the largest dimension (the length L4 for the orientation shown in Figures 1 and 2) of the second inlet 36, measured approximately parallel to the transverse axis Y-Y of the spout 10, when divided by the width w2 or w3 of the wet cleaning cloth folded 12. This ratio should produce a value of at least about 0.7. Desirably, the value will be at least about 0.75 and more desirably, the value will be at least about 0.8. By adhering to this criterion, one can ensure that the individual wet wiping cloths 12 can be removed through the second inlet 36 in a reasonable manner regardless of how many wet wiping cloths 12 remain in the stack 14 or 20 that is housed therein. the supplier 10.

This relationship does not depend on how many wet cleaning cloths 12 are assembled to form the stack 14 or 20 that is housed in the spout 10. This relationship also does not depend on how the cleaning cloths 12 are interfolded, interspersed or if the wet cleaning cloths are adjacent 12. they are joined by a breakable tear line. Furthermore, this ratio does not depend on any particular liquid composition which is used to impregnate the substrate used to form the wet cleaning cloth 12. Instead, the ratio quantifies the largest dimension of the second inlet 36, measured parallel to the axis cross-section Y- And of the spout 10, divided by the width w2 or w3 of the folded wet cleaning cloth 12. By adjusting these two parameters to arrive at a value of at least about 0.7, one can have confidence that the individual wet cleaning cloths 12 can be easily supplied through the second inlet 36.

Although the invention has been described in conjunction with several specific embodiments, it should be understood that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Therefore, this invention is intended to encompass all those alternatives, modifications and variations that fall within the spirit and scope of the appended claims.
