The present invention relates to a device for treating a region of the human body, for example, the hands, the face, or the hair.
It may be beneficial to provide a treatment device which is easy to use, agreeable, and relatively simple to manufacture.
An exemplary treatment device in accordance with the invention may comprise a cover defining a cavity configured to receive a part of the body. The cover may comprise at least one sheet having a composite structure comprising at least one adhesive matrix situated between at least two layers, wherein at least one of the two layers may be permeable to a solvent. The two layers may be permanently bonded, directly or indirectly, to the adhesive matrix. The adhesive matrix may contain at least one active agent that is soluble in the solvent. The active agent, once dissolved, may be suitable for release from at least one side of the cover.
As used herein, two or more structural elements that are “permanently bonded” to each other cannot be readily separated from one another through the use of a completely manually-applied pulling force. For example, a release layer in contact with an adhesive on a bandage would not be “permanently bonded” to the remainder of the bandage.
An exemplary treatment device may easily perform treatment once all or part of the cover has been put into contact with the solvent, for example water. The treatment can take place inside the cover, outside the cover, or both inside and outside.
When the treatment takes place inside the cover, the active agent may be released on contact with the part of the body placed inside the cover, for example, a hand. The cover can facilitate the action of one or more active agents released on contact with the treated region, reinforcing the effectiveness of the treatment and, where appropriate, adding a thermal effect suitable for improving penetration of the one or more active agents into the skin.
When the treatment takes place outside the cover, the treatment device may be used like a face cloth, for example. A massaging action may be combined with an action of applying one or more active agents and/or with an action of cleaning the skin.
The cover may be in the form of a glove, for example, a mitten, so as to enable a hand to be treated and/or so as to enable the cover to be used to treat some other part of the body.
The cover may alternatively be in the form of a cap for placing over the head of a user for treating the hair or the scalp.
Alternatively, the cover may be in the form of a finger glove so as to enable a finger to be treated.
It should be appreciated that the cover may have various other forms. For example, the cover may be formed as a hood configured to treat the hair and/or the face, a sock, or a bag for placing around an ear, for example.
The cover may be elasticized, for example, around an opening where the inside of the cover communicates with the outside. The elasticized opening may hold the cover better on the part of the body that is received inside. The elasticized opening may allow the cover to form a bag.
The cover may be made out of a single sheet that is folded over onto itself or shaped to form a bag. Alternatively, the cover may be made from two or more sheets that are assembled together.
When two sheets are assembled together, assembly may be performed over a portion of the periphery of the sheets, so as to leave an opening for inserting a part of the body.
The sheets may be assembled together by, for example, heat-sealing, adhesive, or stitching.
The cover may have slots or openings disposed in a staggered configuration as in expanded metal, so as to be extensible to some extent.
According to an exemplary embodiment, the adhesive matrix may contain one or more active agents that are soluble in the solvent used and/or capable of swelling on coming into contact with the solvent. The agents may be introduced into the matrix in sufficient quantity for the matrix to lose its cohesion on contact with the solvent so as to release one or more of the active agents more easily. Alternatively or additionally, the adhesive matrix may contain a filler of one or more compounds capable of swelling on contact with the solvent. The filler may be introduced into the matrix in sufficient quantity for it to lose its cohesion on coming into contact with the solvent and for it to release one or more of the active agents more easily. Alternatively or additionally, the adhesive matrix may contain a filler of one or more substantially inert compounds in sufficient quantity for the matrix to lose its cohesion on contact with the solvent and thus release one or more of the active agents more easily.
The adhesive matrix may comprise one or more moisture-absorbing compounds, for example, 0.2% to 60% by weight of a moisture-absorbing compound, or 0.5% to 40% by weight of a moisture-absorbing compound. The compound may be selected from polyacrylates, silicas, cotton fibers, starches, alginates, calcium and magnesium carbonates, viscose, cellulose, lyophylisates, and the like. In addition to (or in the alternative to) moisture-absorbing compounds, the adhesive matrix may include one or more substances capable of reducing its adhesive power and enabling it to burst on contact with the solvent so as to facilitate release one or more of the active agents. The substances may comprise, for example, substantially inert substances such as microbeads or a powder of an inert compound, for example, the polyamide powder known by the name ORGASOL.
The adhesive matrix may include one or more active agents selected from vitamin C, vitamin A, vitamin F, glycerin, laponite, wetting agents, collagen, salicylic acid, tio acid, essential aromatic oils, coloring agents, caffeine, anti-oxidants, free radical scavengers, moisturizers, depigmenting agents, liporegulators, anti-acne agents, antidandruff agents, anti-aging agents, softeners, antiwrinkle agents, keratolitic agents, anti-inflammatory agents, fresheners, healing agents, vascular protectors, antibacterial agents, antifungal agents, antiperspirants, deodorants, skin conditioners, anesthetics, immunomodulators, and nourishing agents, and the like.
The adhesive matrix may also include particles that are magnetic or magnetizable for improving microcirculation. The composite structure may include, for example, at least two layers of magnetizable particles capable of generating respective magnetic fields of different polarities.
The solvent may be a solvent other than water, for example, an oil or a lotion.
An exemplary treatment device in accordance with the invention may make it easy to package one or more active agents by incorporating them in one or more adhesive matrices. Storage may be performed in the anhydrous state under good conditions since it may be possible for the cover to be impregnated with solvent only at the time of use. This may make it possible to avoid using preservatives or to reduce the concentration thereof. Packaging may also be made simpler.
The mass per unit area of the matrix may range from 10 grams per square meter (g/m2) to 100 g/m2, for example.
In an exemplary embodiment, one of the layers in contact with the adhesive matrix may comprise a non-woven fabric. Optionally, the non-woven fabric may be laminated with a peel-off film, a net, a web, a woven cloth, a sponge, a felt, or the like. The adhesive matrix may be between two porous layers, each layer comprising, for example, a non-woven fabric.
The inside and outside faces of the cover may have different roughnesses. The layers between which the matrix is situated may have different thicknesses and/or pore sizes so as to make two different types of application possible, depending on which face is selected by the user, for example, by turning the cover inside out. The outside and inside faces of the cover may have different colors so as to make them easily identified by the user.
One surface of the cover, for example, the inside face, may comprise a heat-sealable web thereon. One of the two layers may comprise a non-woven fabric having two opposite surfaces, wherein the heat-sealable web may be on one of the surfaces of the non-woven fabric, and the other surface of the non-woven fabric may be bonded to the adhesive matrix. It should be understood that the web is not essential, it being possible for the sheet(s) constituting the cover to be assembled in numerous ways.
In an exemplary embodiment, the composite structure may include a layer that is impermeable or partially occlusive (i.e., semi-permeable) so as to encourage diffusion of an active agent into the skin by retarding evaporation of the solvent. This impermeable or partially occlusive layer may be between the matrix and the outside of the cover when the treatment is to take place inside the cover. In this configuration, the impermeable or partially occlusive layer may contribute to retaining the solvent inside the cover, which may be desired, for example, when the solvent is volatile or when only a small quantity of solvent is introduced into the cover.
The composite structure may also include at least two juxtaposed or superposed adhesive matrices of compositions. The compositions may be identical or different. For example, it may be desirable to assemble together two or more adhesive matrices in order to obtain a desired combination of active agents rather than attempt to incorporate all of the agents in a single adhesive matrix. For example, a given adhesive matrix may be manufactured in large quantity with one or more selected active agents. The matrix may then be assembled with one or more different adhesive matrices containing other active agents so as to build up a range of composite structures having a variety of properties.
According to an exemplary aspect of the invention, the composite structure may comprise, in order, the following superposition of layers: a first layer that is permeable to the solvent, a first adhesive matrix, a second adhesive matrix, and a second layer that is permeable to the solvent. According to another exemplary aspect, the composite structure may comprise, in order, the following superposition of layers: a first layer that is permeable to the solvent, a first adhesive matrix containing at least one active agent, an impermeable intermediate layer, a second adhesive matrix containing at least one active agent, and a second permeable layer. The first and second adhesive matrices may contain different active agents.
Such composite structures may be manufactured by coating each permeable layer separately in an adhesive matrix. The coated layers may then be assembled, either directly or otherwise, about an intermediate layer, for example, an impermeable layer or a permeable layer.
According to another exemplary aspect, the composite structure may include a first adhesive matrix comprising two juxtaposed regions containing different active agents. The composite structure may optionally comprise a second adhesive matrix likewise comprising two juxtaposed regions containing different active agents, for example, active agents that are different from those contained in the first adhesive matrix. This configuration may increase the number of combinations of active agents within a given composite structure and/or to adapt the distribution of the agent to the nature and the positioning of the zones to be treated.
The composite structure may also be arranged in such a manner as to encourage diffusion of one or more of the active agents contained in the adhesive matrix towards one of the faces of the cover. To create diffusion towards a face of the cover defined by a solvent-permeable layer, for example, a non-woven fabric, the adhesive matrix may be placed in the fluid state on the solvent-permeable layer so as to enable diffusion at least in part between the fibers or particles of the solvent-permeable layer, over at least a portion of the thickness thereof.
According to another exemplary aspect of the invention, a method of manufacturing a device for treating a part of the body is provided. The method may comprise providing at least one sheet comprising a composite structure of at least one adhesive matrix present between two layers, wherein at least one of the layers is permeable to a solvent. These two layers may be permanently bonded to the adhesive matrix. The adhesive matrix may contain at least one active agent soluble in the solvent and suitable, once dissolved, for being released through at least one side of the sheet. The method may also comprise folding the at least one sheet over onto itself or shaping it into a bag or assembling it with at least one other sheet, so as to create a cover defining a cavity in which a part of the body may be received.
According to another exemplary aspect, the composite structure can be made by coating a first layer with an adhesive matrix based on permanent adhesive, where the adhesive matrix contains at least one active agent and possibly a filler. The nature and the quantity of the active agent and/or the filler may be selected to enable the active agent to be released when the composite structure is wetted by a solvent. A second layer may be assembled with the coated first layer so that the adhesive matrix is sandwiched between the two layers. The layers may be bonded together permanently by the matrix, either directly or indirectly. At least one of the two layers may be permeable to a solvent capable of dissolving the active agent contained in the matrix. The second layer may be coated on one face in a second adhesive matrix, and the two adhesive matrices can then be stuck together. The two adhesive matrices may be united, even if they are identical in composition, so as to provide two different outer layers, for example, to obtain two faces offering specific application characteristics.
It should be appreciated that one or more exemplary aspects of the invention may make it easier to manufacture independently and in large quantities, for example, permeable layers each coated in an adhesive matrix containing one or more predetermined active agents. Subsequently, various combinations of active agents may be made by selecting which layers are to be assembled together depending on the use for which the treatment device is intended. For example, a composite structure may be made having two outside layers and two adhesive matrices containing active agents that need to be stored separately.
According to another exemplary aspect of the invention, various methods of treatment, such as cosmetic and/or dermatological treatment are provided. For example, a method of treating a part of the body may comprise inserting the part of the body to be treated inside the cavity defined by the cover of the treatment device and placing the cover in contact with a solvent. For example, the body part may be introduced before or after placing the cover in contact with the solvent.
Optionally, massaging motion may be imparted between the cover and the part of the body inserted therein. Such massaging may encourage the release of one or more of the active agents inside of the cover.
Optionally, after a first treatment, the cover may be turned inside-out and treatment may be started over using the inside-out cover.
An exemplary treatment method may also include selecting between two different faces of the cover prior to performing a first treatment.
A treatment device in accordance with one or more exemplary aspects of the invention may be used for any treatment in general. The treatment may be therapeutic. For example, the device may be used for treating diseases such as acne, cutaneous herpes, psoriasis, or the like.
In accordance with another exemplary aspect of the invention, a method of treating at least a portion of at least one hand may comprise inserting a hand into a glove comprising a cover as defined above and placing the cover in contact with solvent. For example, the hand may be inserted before or after placing the cover in contact with the solvent.
According to another exemplary aspect of the invention, a glove for treatment of at least a portion of at least one hand may include, for example, at least one moisturizing, anti-chapping, anti-herpes, burn-care, or eczema-care agent, or an agent that promotes healing.
Aside from the structural and procedural arrangement described above, the invention could include a number of other arrangements, such as those explained hereinafter. It is to be understood that both the foregoing description and the following description are exemplary and explanatory only and are not restrictive of the invention.
The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification. The drawings illustrate some exemplary embodiments of the invention and, together with the description, serve to explain some principles of the invention. In the drawings,
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings and in the description to refer to the same or like parts.
In accordance with the invention, a closure system for a container is provided. Referring to
In the exemplary embodiment of
At least one of the two sheets 11 and 12 may include an adhesive matrix placed in permanent manner between at least two layers, optionally, in direct contact with the layers. The adhesive matrix may contain at least one active agent, and at least one of the layers may be permeable to a solvent such as, for example, water. The solvent may be capable of dissolving the active agent in order to cause it to be released while in contact with the surface to be treated.
The active agent may be released inside the cavity formed by the cover, outside the cavity, or both inside and outside, depending on the intended application.
The invention is not limited to a treatment device in the form of a glove.
For example,
The exemplary treatment devices described above may include sheets comprising various composite structures. Some exemplary composite structures are described below.
For example,
The adhesive matrix II may be based on a permanent adhesive which is not soluble in the solvent. The permanent adhesive may ensure that the two layers I and III remain together, even when the composite structure is wetted. The adhesive matrix II may contain, for example, at least one water-soluble active agent for cleaning, making up, or caring for the skin or the hair, and a filler enabling it to release at least one of the active agents it contains when the composite structure is impregnated in solvent. The adhesive matrix II may be based on vinyl compounds, polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), a pseudo-latex such as acrylic polymers, polyurethane, latex elastomer, or the like. The selected adhesive may be reversible, for example, PVA and PVP, or not reversible, for example, acrylics, vinyl compounds, polyurethanes, and latex elastomers.
When the solvent is water, the adhesive matrix II may contain a filler capable of enabling it to absorb water so that it loses its cohesion and so that the water-soluble active agents it contains may be released more easily when the composite structure is wetted. The filler may comprise particles of a water-absorbing material, such as a polyacrylate, for example.
In general, it is possible to incorporate 0.01% to 50% active agents in the adhesive matrix II, for example, agents selected from vitamin C, vitamin A, vitamin F, laponite, glycerin, wetting agents, collagen, salicylic acid, essential aromatic oils, coloring agents, and caffeine. It may also be possible to incorporate in the adhesive matrix a powder filler of an inert material, for example, ORGASOL.
Layers I and III may comprise various permeable flexible components that are optionally extensible, such as, for example, a textile film, a non-woven fabric, a cellular material such as a foam, a felt, or any laminated material including one of the above components laminated with one or more other components selected from the above components. One of the layers I and III can also include one or more flexible components that are impermeable or possibly occlusive, for example, a plastics film, optionally metal-coated, or a sheet of metal. The layers I and III may, by the nature of the materials from which they are made, be intrinsically hydrophilic or hydrophobic and may be subjected to treatment for making them hydrophilic or hydrophobic. The layers I and III may have different thicknesses, different natures, different colors, different roughnesses, or the like.
At least one of the layers I and III may have perforations 100 (e.g., slots) as shown in
At least one of the layers I and III may be coated in flocking 105, as shown in
The composite structure may comprise an adhesive matrix II sandwiched between layers I and III of different thicknesses, as shown in
One of the layers I and III of the sheet may have a surface web 110 to make it easier to assemble with another sheet, for example, by heat-sealing, as shown in
In order to encourage active agents to diffuse towards one face of the cover, the matrix may impregnate one of the layers I and III through at least a fraction of its thickness, as shown in
A plurality of adhesive matrices may be superposed directly or indirectly, thus making it possible to create a wide variety of combinations of active agents and/or support layers having different properties. The adhesive matrices be assembled together in various ways, for example they can be stuck together or they can be individually sandwiched between layers that are permeable or impermeable.
For example,
The intermediate layer 115 may be impermeable, in which case the active agents contained in the matrix IIb will not diffuse towards the matrix IIb, and vice versa. Alternatively, the intermediate layer 115 may be permeable.
For example, the adhesive matrices IIa and IIb may contain different active agents, for example, active agents unsuitable for being packaged together.
In order to make the composite structure shown in
It should be appreciated that a plurality of layers may be made independently, wherein each layer may be impregnated with an adhesive matrix containing predetermined active agents. Subsequently, the coated layers may be assembled so as to obtain a desired combination of active agents.
For example, the region IIc may contain vitamin C, the region lid may contain an enzyme, the region lie may contain bicarbonate, and the region IIf may contain citric acid. After the cover has been put into contact with a solvent such as water, these various compounds may be released and may form foaming retinol for treating signs of aging.
For example, a treatment glove as in
The invention is not limited to the examples described above. For example, other combinations of layers and adhesive matrices can be used.
The adhesive matrix may also be used as a supply of active agents with the composite structure being wetted several times over.
It may be possible to use a solvent other than water for wetting the composite structure, and said solvent may be compatible with external use on the user.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure and methodology of the present invention. Thus, it should be understood that the invention is not limited to the examples discussed in the specification. Rather, the present invention is intended to cover modifications and variations.
