BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to impregnated and non-impregnated wipes and pads. More particularly, the present invention relates to the inclusion of a formulary reservoir to provide additional formulary within the package structure incorporating the wipes and pads as well as to materials and packaging for wipes and pads providing for improved performance and user protection.
2. Description of the Related Art
Various types of wipes, pads and applicators are available in the marketplace. Such wipes, pads and applicators are used for the application of a variety of formularies, such as lotions, sunscreen, insect repellents, and cleaning fluids. These wipes, pads or applicators are typically marketed as an alternative means to distribute a formulary of the particular company marketing the formulary. For instance, an insect repellent company having a proprietary insect repellent may market an insect repellent wipe, a suntan lotion company may market a suntan lotion wipe, and a cleaning fluid company may market a cleaning fluid wipe. For the purposes of simplified description, the inventor will detail the invention around impregnated wipes assuming that impregnated pads and various applicators are one in the same for the application of formulary and that the absorption of liquids or compounds is understandable as a reverse process of application of an impregnated substance.
For the purpose of applying a selected formulary to a surface, a material is impregnated with the selected formulary. The material impregnated with the formulary constitutes the wipe, pad or applicator. A formulary reservoir is integrated into the package structure to dispense new or additional formulary to the wipe, pad or applicator material to provide additional coverage of said formulary to the prescribed surface. The wipe, pad or applicator is then packaged for user convenience and to protect the wipe, for example, from evaporation or contamination, or both.
SUMMARY OF THE INVENTIONWith the increasing popularity of the use of impregnated wipes, pads and applicators for the convenient application of formularies, numerous products developed by companies have not been marketed for use as impregnated wipes. One reason for this unavailability of formularies in impregnated wipes, pads and applicators appears to be the high probability of transdermal migration of the formulary contained in the impregnated wipe through the skin of the user's hand or body parts when in contact with the impregnated wipe. Certain formularies should not come in contact with the skin including products that are toxic, could discolor the skin, have undesirable odors or may leave the user's skin in a condition that the user may not like.
Additionally, numerous pharmaceutical products are intended to be applied only to the point of medical problem and transdermal migration through the user's skin might constitute an overdose of the medication. Further, users of impregnated wipes may not want to receive any formulary on their skin when applying formulary to surfaces other than their own body.
Another reason for the lack of certain formularies in impregnated wipes, pads and applicators is because the methods and processes for the packaging surrounding the impregnated wipe have not addressed the user's need for a secure way to grip or hold the impregnated wipe, pad or applicator and additionally prevent transdermal migration. Further, current systems and methods, anticipated through the prior art, do not provide the capability of a formulary reservoir to dispense additional liquid to the adhered wipe/pad substrate so that the “Barrier Package” will be able to apply the intended formulary to a greater surface area. The present invention solves these and other problems in a manner not revealed in the known prior art and represents a further improvement over this inventor's U.S. Pat. No. 6,305,531 and the related Pending application No. 20030106812.
There are many different impregnated wipes available. Typically, impregnated wipes are pulled out of a bulk container or removed from a single use package prior to usage. The user's skin (hand) will come in contact with the formulary impregnated into the wipe. Additionally, the way that impregnated wipes are delivered to consumers and businesses, in the marketplace, has limited their usage in conjunction with formularies that stain, have undesirable smell or texture, or might present toxic exposure. Examples of known formularies that user's may not want in contact with their skin include: shoe polish, stains, paints, solvents, lubricants, pharmaceuticals and any potential toxic substance.
Based on the foregoing, consumers and businesses are in need of a way to exploit the convenience and portability of impregnated wipes and pads in accordance with formularies that are undesirable when in contact with the user's skin. Accordingly, one aspect involves an innovative approach to improving methods, systems and processes in packaging and impregnated wipe materials to prevent the unwanted migration of formulary from the impregnated wipe to the user's skin.
One aspect involves a wipe package having an impregnated wipe, a sealed package containing the wipe, pad or applicator, and an adjacent formulary reservoir wherein the sealed package has an exterior surface. Further, the wipe package includes at least one receptacle on the exterior surface to secure the package to a user's hand or finger when using the impregnated wipe.
Another aspect involves a applicator package having an impregnated wipe and a non-permeable layer on a rear surface of the impregnated wipe and adjacent formulary reservoir wherein at least the non-permeable layer seals the impregnated wipe in a folded and closed condition.
A further aspect involves wipe package having an impregnated wipe, a sealed package containing the impregnated wipe and having an exterior surface, an adjacent formulary reservoir and at least one receptacle on the exterior surface to secure the package to a user's hand or finger when using the impregnated wipe. The sealed package includes a front sheet, a first rear sheet having an interior surface and an exterior surface, and a second rear sheet. The impregnated wipe is secured to an interior surface of the first rear sheet, and at least the front sheet and the first rear sheet seal the impregnated wipe. The receptacle is formed between the exterior surface of the first rear sheet and the second rear sheet.
Another aspect involves a wipe package having an impregnated wipe and a sealed package containing the impregnated wipe, wherein the sealed package has an exterior surface. The wipe package contains at least one or more adjacent formulary reservoir/s to provide said formulary to the wipe or pad. Further, the wipe package has at least one receptacle on the exterior surface to secure the package to a user's hand or finger when using the impregnated wipe. The sealed package includes a front sheet, a rear sheet, and a non-permeable layer on a rear surface of the impregnated wipe. At least the front sheet and the non-permeable layer seal the impregnated wipe. The receptacle is formed between the rear sheet and the non-permeable layer of the impregnated wipe.
A still further aspect involves a wipe package having an impregnated wipe and a sealed package containing the impregnated wipe, wherein the sealed package has an exterior surface. The wipe package contains at least one or more adjacent formulary reservoir/s to provide said formulary to the wipe or pad. The wipe package has further at least one receptacle on the exterior surface to secure the package to a user's hand or finger when using the impregnated wipe. The sealed package includes a front sheet and a rear sheet, which seal the impregnated wipe, and wherein the rear sheet includes the receptacle.
Another aspect involves a wipe package having an impregnated wipe and a sealed package containing the impregnated wipe, wherein the sealed package has an exterior surface. The wipe package contains at least one or more adjacent formulary reservoir/s to provide said formulary to the wipe or pad. The wipe package includes at least one receptacle on the exterior surface to secure the package to a user's hand or finger when using the impregnated wipe, wherein the sealed package includes a front sheet and a rear sheet, which seal the impregnated wipe, and wherein the rear sheet includes the receptacle. An adhesive layer on an exterior surface of the rear sheet is configured to adhere to at least a part of the user's hand.
A further aspect involves a method of manufacturing a wipe package. A packaging material having an interior surface and an exterior surface is provided and a receptacle is formed on the exterior surface of the packaging material. An impregnated wipe is sealed with the packaging material so that the interior surface faces the impregnated wipe, wherein the receptacle is configured to secure the package to a user's hand or finger when using the impregnated wipe. The wipe package contains at least one or more adjacent formulary reservoir/s to provide said formulary to the wipe or pad.
Another aspect involves a wipe package having a rear sheet of packaging material and two impregnated wipes. A first impregnated wipe is attached to the rear sheet, and a second impregnated wipe is attached to the first impregnated wipes. The second impregnated wipe is removable from the first impregnated wipe to expose the first impregnated wipe for use. The wipe package contains at least one or more adjacent formulary reservoir/s to provide said formulary to the wipe or pad.
A wipe or pad in accordance with certain embodiments significantly reduces and or eliminates the transdermal migration of unwanted formulary from the impregnated wipe to the user's skin. A non-permeable barrier exists between the user's skin and the impregnated wipe providing a new improved way to exploit the convenience of impregnated wipes for a greater variety of formularies. For example, the non-permeable barrier is a part of the impregnated wipe packaging or included on one side of the impregnated wipe material. The formulary reservoir integrated into the wipe package provides a means to increase the amount of formulary available for application to the specified surface.
A wipe or pad in accordance with certain embodiments has the advantage of improving the ability of the packaging to stabilize the location or grip, in the user's hand, of the impregnated wipe while using it to apply the formulary. The one or more adjacent formulary reservoirs have the advantage of providing new or additional formulary to the wipe/applicator/pad and or providing the opportunity to mix ingredients (compound and solvent) prior to application.
Preferably, one layer of the packaging may be removed from a second layer to expose the impregnated wipe's surface for application of the formulary. The exposed impregnated wipe is attached to the second layer by a variety of techniques that are known in the art. The second layer acts as the intermediate layer wherein the formulary reservoir is integrated to provide the user the ability to deliver additional or new formulary to the wipe/pad material attached to the second layer. A third layer provides a non-permeable membrane between the impregnated wipe and the user's hand (skin). The fourth layer is attached to the third layer forming a pocket or strap for the insertion of the user's finger(s) or hand to provide additional package stabilization.
Using any of the herein described methods to secure the finger(s) or hand to the impregnated wipe, the active formulary surface may be exposed by separating the edges of the impregnated wipe, maintaining the hand or fingers to the non-permeable coating of the impregnated wipe by die-cut hole, strap or adhesive and effectively applying the wipe formulary without causing transdermal migration. The user may then press on the adjacent reservoir/s to deliver additional formulary to the wipe/applicator/pad.
