Various different types of disposable wiping products are currently available on the market. Such wiping products can include, for instance, facial tissues, bath tissues, paper towels, napkins, and the like. In addition to dry products, saturated or pre-moistened wiping products have also gained in popularity in the recent past.
Saturated or pre-moistened wiping products are used in a variety of different wiping and polishing applications. For instance, pre-moistened wipes are commonly sold in a stack of individual, folded sheets packaged in a plastic container for use as baby wipes. In other applications, the wipes are treated with an antibacterial agent and packaged as a sanitary wiper.
Pre-moistened wipes are also produced containing a disinfectant and/or a cleaning composition. In these applications, the pre-moistened wipes are used to clean and disinfect adjacent surfaces, such as countertops, flooring, and bathroom surfaces.
Pre-moistened products are also constructed that disintegrate when placed in water over a period of time. These products are marketed as being “flushable” down a standard commode. Such pre-moistened wipes are gaining in popularity as a replacement to dry bath tissue.
Wiping products, such as those described above, are packaged in various different formats. For instance, the wiping products can be packaged in containers made from plastic or from paperboard. The package can be configured to contain a relatively large number of wipes or, for some pre-moistened wipes, configured to only contain a single wipe. What is needed, however, is a package for carrying a relatively small amount of wipes for individual use. For instance, in some applications, a need exists for a package for pre-moistened wipes that can be discretely carried by an individual. Such a package, for instance, may be particularly well suited to holding flushable pre-moistened wipes.
In general, the present disclosure is directed to a package for carrying wipes. In one embodiment, for instance, the package includes a first compartment containing a first product and a second compartment containing a second product. The second compartment can have a length and a width that are substantially similar to the length and width of the first compartment.
The first compartment is connected to the second compartment along a foldable seam. In particular, the first compartment is foldable onto the second compartment about the seam. When in a folded configuration, an inner surface of the first compartment faces an inner surface of the second compartment.
A first opening is located on the inner surface of the first compartment for withdrawing products therethrough and a second opening is located on the inner surface of the second compartment for withdrawing products therethrough.
In one embodiment, the package can have a wallet-like configuration. Although the size and shape of the package can vary depending upon the particular application, in one embodiment, the length and width of each compartment can be from about 2 inches to about 6 inches.
In general, any suitable product may be contained in the first and second compartments. In this regard, the opening associated with each compartment can vary depending upon the particular type of product contained within the compartment. In one embodiment, for instance, the first product and the second product may comprise at least one wipe, such as a stack of wipes. The wiping product may be, for instance, a facial tissue, a bath tissue, and the like. The product that is contained in the first compartment may be the same or different than the product that is contained in the second compartment. In one particular embodiment, the first compartment and the second compartment both contain pre-moistened wipes. In an alternative embodiment, the first compartment may contain dry wipes, such as facial tissue, while the second compartment can contain pre-moistened wipes, such as pre-moistened bath tissue.
When designed to carry wipes, each compartment can contain from about 1 wipe to about 25 wipes, such as from about 5 wipes to about 20 wipes.
It should be understood, however, that various other consumable products can be contained within the first and second compartments. Other products that may be contained in the compartments includes, for instance, liquid or semi-solid products, such as skin care compositions, cleaning agents including disinfectants, insect repellants, and the like. Still other products that may be contained within the compartments include fragrance products, medicated pads, cosmetic products, non-woven pads, rubber gloves, finger gloves, condoms, and the like. In one particular embodiment, the first product contained within the first compartment may comprise a different product than the second product contained in the second compartment. The first product and the second product, however, may be selected such that they are used together. For instance, in one embodiment, the first compartment may contain a liquid or a semi-solid product while the second compartment may comprise an applicator for the first product.
If desired, the opening defined by the first compartment and the opening defined by the second compartment can be resealable. For instance, in one embodiment, the openings can be covered by an adhesive label that can be peeled and resealed. The adhesive label may comprise a film defining a peelable member surrounded by a frame portion. The peelable member can be attached to the frame portion along a fold line. In one particular embodiment, the peelable member may include a tab portion that extends beyond the perimeter of the frame portion.
In an alternative embodiment, each opening may be covered by a polymeric member that defines a slit. The polymeric member may be constructed such that the slit forms an opening when the polymeric member is compressed in a direction generally parallel to the slit.
In still another embodiment, each opening may include a first side and a second side. The first side may be surrounded by a groove, while the second side may be surrounded by a ridge. The groove and the ridge may form an interlocking fit. In this embodiment, a closing member may be present in order to facilitate the mechanical interlock between the groove and ridge. In particular, the closing member may function like a zipper in that it may slide along the groove and ridge forcing the two structures together. Alternatively, the groove and ridge can be closed by sliding a finger along the opening.
In still another embodiment, the first and second openings can be located on the first and second compartments so as to overlap when the package is folded. The package can include a sealing member that seals the first opening to the second opening when the package is folded. For instance, the sealing member may comprise a female portion positioned adjacent the first opening and a male portion that is positioned adjacent to the second opening. The female portion may form an interlock fit with the male portion when the package is folded. For example, the female portion may comprise a groove, while the male portion comprises a ridge that fits within the groove.
In another embodiment, at least one of the openings may comprise an open end of the compartment for withdrawing products therethrough. For instance, the open end can be accessible from the inner surface of the compartment and can face the seam. Compartments with an open end are particularly well suited to holding, for instance, dry wipes, such as facial tissues and the like.
In still another embodiment, one of the openings in the compartments can be initially closed by a frangible seal. The frangible seal may be configured to be opened by a user for exposing the product inside. Examples of frangible seals that may be used in the present disclosure are disclosed, for instance, in U.S. Pat. No. 5,616,337, U.S. Pat. No. 6,705,541, and in PCT Publication No. WO 02/42176, which are all incorporated herein by reference. A frangible seal generally refers to a seal that once opened by a user is not resealable. Compartments having a frangible seal are particularly well suited to holding moistened products, liquid products, and semi-solid products.
It should be understood that the different types of openings described above may be used in conjunction with each other as desired. For instance, in one embodiment, the first compartment may have an open end while the second compartment may have a resealable opening or an opening closed by a frangible seal.
In still another embodiment, the package can include a third compartment. The third compartment, for instance can be superimposed on the inner surface of the first compartment or the second compartment. The third compartment can be configured to hold a third product and can have any suitable opening as described above. For instance, in one embodiment, the third compartment may have an open end.
The package can generally be made from any suitable material. In one embodiment, for instance, the package may be made from a polymer film material. The polymer film material may comprise a multi-layered polymer film. For instance, the polymer film may include a sealable layer that faces the wipes within the compartments and an opposite outside layer. Optionally, a core layer may also be present that is positioned in between the sealable layer and the outside layer. The core layer may be more rigid than the sealable layer and outside layer for providing support to the product.
The sealable layer can be made from any suitable thermoplastic polymer that is capable of fusing when subjected to, for instance, heat or ultrasonic energy. The sealable layer, for instance, may be made from a polyolefin polymer, a polyolefin copolymer, or an ethylene vinyl acetate copolymer. The outside layer, on the other hand, may comprise a polyolefin polymer or a copolymer thereof. The outside layer may be printed with graphics and can also be embossed.
The present disclosure is also directed to a process for producing a package for consumable products. The process can include the steps of placing a first product, such as a stack of wipes on a first portion of a blank and placing a second product, such as a second stack of wipes on a second portion of the blank. The blank can include a first end, a second end, and a middle portion. The middle portion may be located between the first portion and the second portion. The blank can comprise a polymer film material.
The first end of the blank can be folded over the first stack of wipes and the free edges of the first end may be attached to the blank. For instance, once folded over the stack of wipes, the free edges of the first end can be thermally bonded or ultrasonically bonded to the blank. Likewise, the second end of the blank can be folded over the second stack of wipes and attached to the blank.
A first opening can be formed in the first end of the blank for withdrawing the first stack of wipes from the first compartment and a second opening can be formed in the second end of the blank for withdrawing the second stack of wipes from the second compartment.
If desired, a score line can be formed along the middle portion of the blank so as to facilitate folding of the first compartment onto the second compartment. In addition, the middle portion can also be perforated for separating the first compartment from the second compartment if a consumer desires to do so.
Other features and aspects of the present disclosure are discussed in greater detail below.
A full and enabling disclosure of the present invention, including the best mode thereof to one skilled in the art, 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 disclosure.
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 invention.
In general, the present disclosure is directed to a package for carrying consumable products, such as wipes. The package can contain, for instance, two compartments that each carry a different product, such as a separate stack of wipes. The wipes contained in the package can be, for instance, facial tissues, napkins, paper towels, and pre-moistened wipes including pre-moistened bath tissue.
In addition to wipes, the package of the present disclosure can also contain various other consumable products. For instance, the package can also contain liquid products and/or semi-solid products. Examples of such products include, skin care compositions, cleaning agents including disinfectants, insect repellants, cosmetic products, and the like. Other possible products that may be contained within the package include fragrance products, medicated pads, various non-woven pads, rubber gloves, finger gloves, condoms, and the like.
In one embodiment, the first compartment can be attached to the second compartment along a foldable seam. Thus, when folded, the package has a wallet-like shape and style.
Of particular advantage, the package is not only configured to contain two different products, but can also carry the products in a relatively discrete manner. For instance, the package can be made to be relatively compact and can be provided with different textures and graphics that, if desired, can have an overall look that is much different than conventional facial tissue packages, baby wipe packages, and the like.

When dispensing dry wipes, the package 10 may need no further structures in addition to the openings 26 and 28. In some applications, especially when at least one of the compartments contains pre-moistened wipes, however, the openings 26 and 28 can be resealable. For example, as shown in
In the embodiment illustrated in
The adhesive label 30 as shown in
In one embodiment, the adhesive label 30 can be transparent or translucent. If desired, various graphics can be printed onto the label. For instance, the label can be printed with instructions or with aesthetic designs. In one particular embodiment, for instance, the label 30 can be printed with designs that may match the exterior surface of the package.
Examples of labels that may be used with the package of the present disclosure are disclosed, for instance, in U.S. Pat. No. 6,428,867 and in U.S. Pat. No. 6,589,622, which are both incorporated herein by reference. Such labels, for instance, may be obtained commercially from Prime Label and Screen, Inc. of Pewaukee, Wis.

Each stack of wipes can comprise separate sheets or can comprise a continuous length of material in which each sheet is separated by perforations.
When stacked as separate sheets, the individual sheets can be separately folded and stacked on top of each other. Alternatively, the sheets can be interfolded.
The number of sheets contained in the first stack 42 and/or in the second stack 44 can vary dramatically depending upon the particular application. For exemplary purposes only, each stack may contain only a single wipe or may contain more than 30 wipes. In one embodiment, for instance, each stack may contain from about 4 wipes to about 25 wipes, such as from about 8 wipes to about 20 wipes. In one particular application, for instance, each stack may contain from about 10 wipes to about 15 wipes, such as about 12 wipes.
The number of wipes in each stack can vary depending upon the particular application of the product. For instance, when holding a lower amount of wipes, the package can be made relatively compact. In this embodiment, the dimensions of the package may be relatively small and may be used as a purse pack, a pocket pack, and the like for on-the-go convenience. When formed into a wallet-like size, for instance, the length and width of the package, for instance, may vary from about 2 inches to about 6 inches.
In other embodiments, however, the package can be configured to hold relatively large amounts of wipes. In this embodiment, the package may be for carrying relatively large amounts of baby wipes or larger counts of other types of similar wiping products.
As shown in
After the end portions 46 and 48 are folded over the stacks of wipes 42 and 44, the free edges of the end portions are then attached to the blank for creating the two separate compartments. The manner in which the edges of the end portions are attached to the blank may vary depending upon the types of material used to form the blank. For instance, in one embodiment, an adhesive may be used in order to attach the edges to the blank. Alternatively, the free edges of the end portions may be thermally or ultrasonically bonded to the blank. More particularly, as shown in
Of particular advantage, by folding the end portion 46 over onto the blank, a folded edge 56 is formed. Similarly, the second end portion 48 forms a second folded edge 58. The folded edges 56 and 58 are relatively soft to the touch and increase not only the comfort but the aesthetics of the resulting package.

The one or more blanks used to form the package 10 can be made from any suitable material. For instance, the blank can be made from a single layer of material or from multiple layers of material. Materials that may be used to form the blank include woven materials, knitted materials, nonwoven materials such as meltblown webs or spunbond webs, plastic films, laminates thereof, and the like.
In one embodiment, for instance, the blank 40 can be made from a multi-layered polymer film. The film may include, for instance, a sealable layer that is placed in contact with the stack of wipes and is particularly well suited for thermally or ultrasonically bonding to itself. In addition, the multi-layered plastic film can also include an outside layer that may have particular characteristics that improve the aesthetics of the package. Optionally, the multi-layered film can also include a core layer that is positioned in between the sealable layer and the outside layer.
The sealable layer, for example, can be made from a polyolefin, such as a low density polyethylene or a polypropylene. The sealable layer can also be made from an ethylene vinyl acetate copolymer or from any other suitable thermoplastic polymer.
The core layer when present, on the other hand, may comprise any material capable of providing some rigidity to the product. The core layer, for instance, may comprise a paper layer, a foil, or a polymer layer, such as a polypropylene or polyester. When using a foil layer as the core layer, the foil may have a thickness of from about 25 gauge to about 48 gauge.
The outside layer, on the other hand, can comprise any suitable polymer film, such as a polyethylene or a polypropylene. The outside layer may contain various softening additives and anti-slip agents, such as a diene that softens the polymer to give it a patina-like feel. In one embodiment, the outside layer can be made from a polymer film that is capable of accepting an ink. Alternatively, the outside layer may be coated with an ink adhering coating. In this manner, various aesthetically pleasing graphics can be applied to the package as may be desired.
In one embodiment, the outside layer may be embossed in order to further soften the layer and to provide the package with some texture.
As described above, the stack of wipes 42 and 44 that may be contained within the package can vary depending upon the particular application. For instance, the package may be configured to hold facial tissues, napkins, paper towels, and the like. The package is also particularly well suited to holding pre-moistened wipes. The pre-moistened wipes may comprise, for instance, flushable pre-moistened wipes, baby wipes, disinfectant wipes, and the like.

If desired, a reinforcing rib can be formed into the polymeric member 60 along its perimeter. The rib may further facilitate the opening of the slit when a compressive force is applied to the polymeric member.
In one embodiment, the polymeric member 60 can be formed from a rubber-like sheet. The rubber-like sheet can have material properties that can be described in terms of the hardness, stiffness, thickness, elasticity, specific gravity, compression set and any combination thereof.
More specifically, the Shore A hardness (as measured by ASTM D2240) of the flexible, rubber-like sheet or material can be about 100 or less, more specifically from about 20 to about 90, and still more specifically from about 40 to about 80, and yet more specifically from about 60 to about 70.
The Gurley stiffness of the flexible, rubber-like sheet or material (as measured by ASTM D 6125-97 “Standard Test Method for Bending Resistance of Paper and Paperboard”) can be about 10,000 milligrams of force (mgf) or less, more specifically from about 100 to about 8000 mgf, more specifically from about 200 to about 6500 mgf, and still more specifically from about 300 to about 1500 mgf.
The thickness of the flexible, rubber-like sheet can be about 10 mil or greater, more specifically from about 10 mil to about 1-10 mil, and still more specifically from about 35 mil to about 60 mil.
The elasticity of the flexible rubber-like material or sheet, as characterized by the tensile stress at 100 percent elongation and measured in accordance with ASTM D412 “Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers”, can be about 10 megapascals (MPa) or less, more specifically from about 0.1 to about 7 MPa, and still more specifically from about 0.5 to about 2.5 MPa.
The flexible rubber-like sheet can have a specific gravity (per ASTM D792) of about 0.80 to 1.21, more specifically 0.88 to about 1.10, and still more specifically from about 0.90 to about 1.0. The flexible rubber-like sheet can have a compression set (per ASTM 395B) of (at room temperature/at 70 degrees C.) about 8/30 to 40/120 and more specifically 15/45 to about 28/100.
An example of some such flexible sheet-like materials include thermoplastic elastomeric (TPE) materials that can be used to provide acceptable dispensing. Materials which can be employed include (but are not limited to): any of the family of styrenic-based TPE's (i.e. styrenic block copolymer compounds); styrenic-based TPE's containing rubber modifiers such as Kraton™, Santoprene™, or other rubber modifiers; Kraton™; Santoprene™; specialty copolymers, such as ethylene-methyl acrylate copolymers (e.g. EMAC™ of the Eastman Chemical Company); thermoset rubbers; polyurethane; alloys; amides; engineering TPE's; olefinic-based; olefinic vulcanizates; polyester-based; polyurethane-based. One such material for the flexible, rubber-like sheet could be that manufactured by the GLS-Corporation of McHenry, Ill., USA and known as resin #G2701. The G2701 material is one of the resins in the product family of TPEs. G2701 is a styrenic-based material and is in the family of Styrenic block copolymer compounds. Some particular properties of the G2701 can be: specific gravity of 0.090 g/cc (per ASTM D792); hardness (Shore A durometer) of 68 (ASTM D2240); and compression set of 24% at room temperature, 96% at 70 deg. C. (per ASTM 395B). Another similar material is known as G2755 and also sold by GLS Corporation. In addition, a lubricant (e.g., wax) can be added to lower the coefficient of friction of the continuous slit which can benefit injection molding, wet wipes dispensing, and physical handling of the flexible orifice. The G2701 TPE resin with ¼% wax additive sold by GLS Corporation and known as #LC217-189 can be used.
