Disposable premoistened wipes are marketed and sold in a variety of different forms. The premoistened wipes generally include a substrate that is saturated with a cleaning or wiping solution. The wiping solution applied to the substrate can vary depending upon the particular application. For instance, the wiping solution can contain an antimicrobial agent, a cleansing agent, a deodorant, a medicament, or the like. The substrate can comprise a nonwoven web containing polymeric fibers, pulp fibers, or a mixture of both. Many premoistened wipes are designed to degrade and disperse in water.
Premoistened wipes are generally packaged and sold to consumers as a stack of single sheets. Premoistened wipes are packaged and sold in various different types of containers. Premoistened bath tissues, for instance, are typically packaged in flexible and liquid-impermeable containers. The packages typically include a resealable opening for dispensing the wipes one at a time without causing the remaining wipes to undergo a loss of moisture. Although these packages are portable and can be carried anywhere, the packages are not well suited for being placed or displayed in a bathroom.
In the past, various other container designs for premoistened wipes have been proposed that can be attached to or hang from a rolled bath tissue dispenser. For example, U.S. Pat. No. 6,997,342, which is incorporated by reference, discloses a dispenser that includes arms which permit a housing to be coupled to a rolled product fixture. The dispenser is particularly designed to dispense individual sheets from a tabletop or from a rolled product fixture as described above.
Although various container designs have been proposed in the past for dispensing premoistened wipes from a rolled bathroom tissue dispenser, various improvements are still needed. In particular, a need exists for a dispenser for dispensing sheet materials from a rolled product fixture that can easily accommodate and hold packages of wipers, such as premoistened wipes. A need also exists for a collapsible dispenser as described above that can be provided to consumers in combination with a package of premoistened wipes and that is easy to assemble and install.
In general, the present disclosure is directed to a collapsible dispenser for dispensing sheet materials from a rolled product fixture. The dispenser can be made from a single sheet of material that can be easily assembled into a housing for receiving a package of sheet materials, such as premoistened wipes. In one aspect, the dispenser is also foldable. When in the folded configuration, for instance, the dispenser can have a length and width that generally matches the length and width of the package of sheet material that the housing is adapted to hold.
In one embodiment, for example, the dispenser comprises a housing having a top defining a cutout portion, a bottom, and an enclosed first end. The dispenser can also include first and second opposing side walls that are positioned between the top and the bottom. The dispenser can further comprise first and second arms. Each arm extends from a corresponding side wall. Each arm is configured to engage a rolled product fixture. The dispenser further includes an open second end for receiving a package containing a sheet of wiping products and wherein the cutout portion of the top is positioned and has a size that corresponds to a dispensing opening on a package loaded into the dispenser.
As described above, the dispenser can be formed from a single blank of material. The material can be a paperboard or can be made from a polymer material. The single blank can include a plurality of fold lines that are positioned to facilitate assembly of the blank into the housing.
In order to engage a rolled product fixture, the first arm can define a first opening and the second arm can define a second opening. The first opening can be located at a first end portion of the first arm while the second opening can be located at a second end portion of the second arm. The first and second end portions are where the first and second arms terminate at their maximum extended position away from the housing. The first arm can be parallel to the second arm in a length direction and the first opening can be in alignment with the second opening in a direction perpendicular to the length direction. The first and second arms can be relatively straight or, alternatively, can have an angled portion that angles away from the housing.
In one embodiment, the first opening can define a first recess portion while the second opening can define a second recess portion. Each recess portion can be directed or pointed towards a terminal end of each arm. In one aspect, the first and second recess portions can be at an angle to the length direction of each side wall. The angle can be, for instance, from about 20° to about 50°. In one embodiment, the first opening and the second opening have a teardrop shape. The above configuration can allow the housing extending from the arms to not lay flat against an adjacent wall but instead assume an upright position that facilitates the dispensing of the premoistened wipes.
As described above, the housing has an open second end for receiving a package containing a stack of wiping products. The top can have a length that is shorter than the length of the package. In this manner, a portion of the package can remain exposed when inserted into the housing. The cutout portion on the top can define an open end and can have a shape that is configured to only partially surround a dispenser opening on a package loaded into the housing. For instance, the cutout portion can surround greater than about 20%, such as greater than about 30%, such as greater than about 40% of the dispenser opening, and generally less than about 80%, such as less than about 70%, such as less than about 60% of the perimeter of the dispenser opening. For example, the cutout portion can be in the shape of a partial oval or in the shape of a partial rectangle.
In one aspect, the bottom of the housing can include a first tab that engages the first side wall and a second tab that engages the second side wall. Each side wall can define a plurality of slots for receiving the tabs. For example, the plurality of slots can be positioned along the width of each side wall and wherein a depth of the housing can be adjusted by selecting one of the slots. For example, the first and second tabs can be inserted into one of the corresponding plurality of slots on each side wall. In this manner, the depth of the housing can be adjusted as the wiping product is dispensed and depleted.
In one aspect, the dispenser of the present disclosure is collapsible. For example, the dispenser can assume a folded configuration that is similar in size to a package designed to be received within the housing. In a folded configuration, for instance, the bottom, the enclosed first end, and the side walls all can be folded onto the top. In addition, the arms can be folded onto the side walls. In this manner, the folded configuration of the housing generally has a rectangular shape and protects the arms from damage.
Other features and aspects of the present disclosure are discussed in greater detail below.
A full and enabling disclosure of the present disclosure is set forth more particularly in the remainder of the specification, including reference to the accompanying figures, in which:
Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present invention.
It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only and is not intended as limiting the broader aspects of the present disclosure.
In general, the present disclosure is directed to a dispenser that is designed to receive a package containing a wiping product for dispensing the wiping product. In accordance with the present disclosure, the dispenser is configured to engage and hang from an adjacent structure for facilitating dispensing of the wiping product. Although the dispenser can be designed to engage any suitable mountable device, in one aspect, the dispenser is particularly well suited for engaging and being attached to a rolled product fixture, such as a bath tissue dispenser. For example, the dispenser can include arms that are designed to engage and extend from a spindle that holds a rolled bath tissue. The arms have a length sufficient so as not to interfere with the unwinding of the bath tissue. The arms, however, also have a configuration that allows for a user to easily remove wiping products from the dispenser. For example, in one embodiment, the wiping product that is held within the dispenser can be a water dispersible and/or flushable product that may comprise, for instance, a premoistened bath tissue.
As will be explained in greater detail below, the dispenser of the present disclosure has a relatively simple design and can be constructed from a one-piece blank. The blank can include fold lines for easily assembling the blank into the dispenser. In a folded configuration, the dispenser can have a length and width that substantially matches the length and width of a package designed to be held by the dispenser. In this way, the dispenser can be marketed with the package and used by the consumer when desired.

Referring to
The angles formed by the arms 44 and 46 and by the recessed portions 56 and 58 serve to better present the wiper products as shown in
In addition, the recesses 56 and 58 are designed to engage rolled product fixtures with different geometries. The recessed portions 56 and 58, for instance, can stabilize the dispenser 10 when engaging a rolled product fixture 60 and keep the dispenser 10 in a more stationary position. The recessed portions 56 and 58, for instance, are well suited for engaging spindles having a circular cross-section as shown in
As described above and as shown in
The blank 50 can also be placed into a compacted folded configuration so that the dispenser 10 can be stored or sold in combination with the package 24. For example, as shown in
Packages for wiping products, such as package 24 in the figures, can have various different dimensions depending upon the particular application and the type of product contained in the package. In one aspect, the package can have a length of from about 16 cm to about 23 cm, a width of from about 8 cm to about 14 cm, and a thickness of from about 1 cm to about 12 cm. The folded blank 50 as shown in
The wiping product contained within the package 24 for use with the dispenser 10 can vary depending upon the particular application. The wiping product, in one aspect, can be contained in the package as individual sheets. The individual sheets can be stacked on top of each other and can be interfolded. The wiping product can be dry or premoistened.
As used herein, the term a “premoistened wipe” refers to a fibrous sheet that has a liquid applied thereto. The amount of liquid or solution contained within each wet wipe can vary depending upon the type of material being used to provide the wet wipe . . . the type of liquid being used, and the desired end use of the wet wipe. Generally, each wet wipe can contain from about 25 weight percent to about 600 weight percent or from at least about 70 weight percent to less than about 400 weight percent liquid based on the dry weight of the wipe. To determine the liquid add-on, first the weight of a dry wipe is determined.
The premoistened wipes, for instance, can include a base sheet that is saturated with a cleaning or wiping solution. In general, the base sheet can comprise any suitable porous wiping substrate. Desirably, the base sheet has a soft and pleasing hand and remains resiliently compressible when wet. The base sheet may be made from continuous fibers, stable length fibers, or combinations thereof. In one embodiment, the base sheet is made from renewable resources, is recyclable, and/or is biodegradable. For instance, the base sheet can be made from natural fibers, such as wood pulp fibers, cotton fibers, bamboo fibers, hemp fibers, and the like. The base sheet may contain a minimal amount of synthetic fibers. Alternatively, the base sheet can be made from synthetic fibers that are water soluble or otherwise biodegradable, such as rayon fibers.
The base sheet can comprise a woven, knit or nonwoven fabric. The base sheet may be a single layer base sheet or can comprise a laminate. Suitable base sheets can have a dry basis weight of from about 25 gsm to about 175 gsm.
Particular embodiments of base sheets that may be contained within the package include air-laid nonwoven webs, wet-laid webs, coform webs, hydroentangled webs, and the like.
In general, any suitable wiping or cleaning solution can be impregnated into the base web. In one aspect, the cleaning or wiping solution can also be environmentally friendly. For example, in one embodiment, the solution impregnated into the base web can be water or an aqueous solution. When the wet wipe is for applying to the skin of the user, for instance, the solution can contain water in combination with one or more surfactants. Other additives that can be present in the solution include antiseptics, emollients, skin conditioners, virucides, antibiotics, fragrances, anti-drying agents, and the like.
When used in conjunction with a rolled product fixture 60 as shown in
The dispenser 10 and the blank 50 can be made from any suitable material. In one aspect, the material used to make the dispenser 10 and blank 50 is sufficiently semi-rigid or rigid in order for the dispenser to be assembled into the three-dimensional configuration as shown in
When the dispenser is made from a paper material, the Gurley stiffness of the package material (as measured by ASTM D6125-97 “Standard Test Method for Bending Resistance of Paper and Paperboard”) can be greater than about 10,000 milligrams of force (mgf), such as greater than about 15,000 mgf, such as greater than about 20,000 mgf, such as greater than about 25,000 mgf, and generally less than about 200,000 mgf.
In an alternative embodiment, the dispenser 10 and blank 50 can be made from one or more polymer layers and may contain no cellulosic fibers. For example, the blank 50 and dispenser 10 can be made from a rigid or semi-rigid polymer film that has sufficient plasticity to retain a fold line as shown in
These and other modifications and variations to the present invention may be practiced by those of ordinary skill in the art, without departing from the spirit and scope of the present invention, which is more particularly set forth in the appended claims. In addition, it should be understood that aspects of the various embodiments may be interchanged both in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims.
