  In a first aspect, the present invention comprises an elastically deformable support; and at least one active agent on one side of the support that acts on the lips, wherein the active agent is A lip treatment patch configured to release an active agent to the lips in response to being contacted with the liquid is provided.

  Wetting the patch acts, for example, to dissolve the active agent and / or to release and / or diffuse it towards the lips. The term “patch” is used to indicate a structure that remains in contact with the surface to be treated, for example by being pushed between the lips. Such a structure need not necessarily adhere to the surface to be treated.

The liquid may be water, saliva, alcohol solution, polypropylene glycol, oil, or other liquid.
Because the patch of the present invention is relatively easy to manufacture and can be packaged in a substantially anhydrous state, the patch is dry to the touch. Thus, the patch does not require a preservative and, if necessary, only contains a relatively small amount of preservative.
Patches can be easily manufactured by cutting from sheets or strips, thus making it possible to avoid having hard ingredients.

  In addition, the patch can be made relatively thick and thus provide some comfort during use and can be pressed between the lips for a relatively long time without excessive user fatigue. The thickness of the support is 2 millimeters (mm) or greater, preferably 3 mm or greater, more preferably 4 mm or greater.

The support may be cellular or any other elastically compressible structure. The support can include a recess. The support can be made of felt, for example.
In the case where the support has a cell structure, it can be composed of open cell or closed cell foam such as polyurethane foam. Where appropriate, the support can be composed of a composite structure in which a plurality of layers are laminated together.

  The device includes: a first substrate on a first side of a support; and a second substrate on a second side of the support; at least an active agent for treating the lips A part can be included in at least one of the aforementioned substrates.

In order to be able to treat the lips symmetrically, the substrates can be identical and contain the same active agent.
By way of example, each substrate can include a fibrous or cellular base, such as a nonwoven or woven sheet, or a sheet of porous film. The base can be water permeable, preferably hydrophilic.

As an example, the active agent can be at least partially dispersed within or between the fibrous or cellular base, particularly in lyophilized or crystalline form.
Each substrate can also include a polymer matrix, which can optionally include at least a portion of the active agent.
This polymer matrix can act in particular to support the base corresponding to the support. Thus, the polymer matrix need not extend to the outside of the patch prior to use, but can be contained between the support and the base combined therewith.

  In a variant, the polymer matrix can constitute the face of the patch that, when in use, will be on the outside, especially if there is no base covering the core. In this case, the polymer matrix is advantageously protected by a removable protective film before use. It is preferred that the polymer matrix is not sticky to the lips when dry, and likewise has little or no adhesion when wet.

Prior to use, the support need not carry an active agent. The active agent can be included in at least one of the two substrates.
The patch can have a symmetrical structure with respect to a central plane intersecting the support at a half thickness of the support. This allows the same processing to be performed on the upper lip and the lower lip, eliminating the need to use the patch in a specific direction.

Activators are, for example, those designed to affect lip cracks or lip fines and / or activators to soften the lips, or indeed external attacks such as cold air or UV radiation Selected from active agents that protect lips from.
The active agent can be selected from, for example, glycerin, allantoine , and jojoba oil.

The patch preferably exhibits a contour that matches the shape of the lips, in particular the shape of a kidney bean, or a contour of a portion of a disk.
The entire patch can be flexible.
If the patch is manufactured by cutting out from a strip or sheet, the patch can allow the support to be seen through its edges.
The substrate placed on either side of the support can already be secured to the support when the user obtains the patch.

In variations, the substrate can include an adhesive to allow the substrate to be secured to the support in use and / or the support secures the substrate to the support in use. An adhesive can be included to allow.
Where appropriate, the adhesive allows the support to be separated from each substrate after use, for example, so that the support can be reused with a new substrate.
Where appropriate, the adhesive may include an active agent.
Patches can be packaged individually or, alternatively, multiple packages can be packaged together.

The present invention also includes an elastically deformable support; and at least one substrate comprising an active agent for acting on the lips; at least one of the support and the substrate is at least for use And a kit comprising an adhesive that allows the substrate and the support to be secured together.
Where appropriate, as described above, the adhesive may act to allow the support and substrate to be separated after use. Where appropriate, the adhesive may include an active agent.

  The present invention also treats lip cracks, particularly to provide healing, treat lip fine lines, soften lips, or protect lips from external attacks such as cold air and ultraviolet radiation In order to provide a method for treating the lips using the patch described above.

  Independently and in combination with the above, the present invention also provides a stretchable deformable support; a first substrate on a surface on the first side of the support; a second of the support A patch for treating the lips is provided, comprising: a second substrate on the side; and at least one active agent contained in each substrate for acting on the lips.

As an example, each substrate can be comprised of a base and a polymer matrix for securing the base to a support.
Optionally, the support can include an active agent for acting on the lips. In particular, the support can be an integral part composed of, for example, an open-cell or closed-cell foam layer.

  Independently or in combination with the above, the present invention provides an elastically deformable support; a first substrate on a first side of the support; on a second side of the support A patch for treating the lips is provided, comprising a second substrate; and at least one active agent contained in each substrate for acting on the lips, formed by cutting the strip.

The present invention may be better understood by reading the following detailed description of the non-limiting embodiments and examining the accompanying drawings.
In the figure, the mutual proportions do not always correspond for clarity.

  The patch 1 shown in FIGS. 1 to 3 is a composite structure and comprises an elastically compressible support 2 located between substrates 3. Each substrate defines the outer surface of the patch 1. In appearance, as can be seen from FIG. 2, the patch has a contour adapted to the shape of the lips, in particular a kidney bean-shaped contour.

  In the illustrated example, each substrate 3 comprises a base 4 and a polymer matrix 5, the polymer matrix 5 extending between the base 4 and the support 2 so as to hold the base 4 on the support 2. Act on. The matrix 5 can be impregnated with the support 2 and / or the base 4 at least partially on the side facing the support 2.

Each substrate 3 contains at least one active agent for the lip treatment action. As an example, the active agent can be included in the base 4 and / or the matrix 5.
The base 4 can particularly improve the comfort during use, and can be composed of a sheet of fibrous or cellular material, such as a woven or non-woven sheet, or it can be composed of a porous film. it can. The base 4 is preferably hydrophilic.

By way of example, the matrix 5 comprises an adhesive, in particular, but not limited to, an adhesive selected from vinyl or acrylic adhesives, polyurethanes, elastomers.
The matrix 5 promotes the bursting of the matrix 5 in the presence of water and facilitates the release of the active agent contained therein, such as at least one hygroscopic compound, for example polyacrylate, silica, in particular colloidal silica. , Carbopol®, and other superabsorbent compounds. As an example, reference may be made to European patent application EP 129 700, the content of which is incorporated herein by reference.

The thickness of the support 2 is preferably 2 mm or more, so that when the user presses the patch 1 between the lips (L), as shown in FIG. For example, 3 mm or 4 mm.
As an example, the support 2 is relatively low density, for example 20 kilograms per cubic meter (kg), which can be easily compressed to allow the user to deform greatly when the patch 1 is held between the lips. / Cm ³ ) to 45 kg / cm ³ .

  The patch 1 is advantageously formed by cutting a composite strip structure so that the support 2 can be seen at the edge 6 of the patch 1, as seen in FIG.

  In the example described, the patch 1 needs to be moistened to allow the active agent to act on the lips. By way of example, the user can only hold a time sufficient to allow at least one active agent to act before holding the patch between the lips (L), for example between 30 seconds and 7 minutes. The patch can be moistened with hot or cold water.

By way of example, water can dissolve, dissociate or release at least one active agent present in the substrate 3, for example at least one active agent contained in the base 4 and / or the matrix 5.
In essence, the present invention is not limited to a particular material for forming the support 2 or the substrate 3, and in the example of FIG. 4, at least one and preferably both substrates are supported. The matrix 5 is constituted by attaching a matrix of hydrogel, for example, to the body surface.

  Each substrate 3 can be protected, for example, by a removable protective film protruding from the support 2 so that it can be easily grasped. In an alternative embodiment, the protective film 8 can be composed of two halves so that the user can bend the patch 1 with each half.

  The support body 2 can form a recess 9 as shown in FIG. In order to make this recess 9, for example, two halves with notches are provided on the surface, and the two halves are assembled to each other by facing the surfaces with the notches of these halves to form a support can do.

  The support 2 can be formed to a constant thickness or different thicknesses as shown in FIG. 6 to further improve comfort during use. As an example, the user may hold the small thickness side of the patch between the lips.

The patch 1 can be provided to the consumer in individual packaging in the form of a case 10 or a bag (not shown) as shown in FIG.
In a modified embodiment, as shown in FIG. 8, the support 2 includes, for example, a base 3 in a case 11 including a recess 12 for receiving the support 2 and a recess 13 for receiving the base 3. Apart from that, it can be packaged in the same case.
The surface of the support 2 can be coated with an adhesive. As an alternative embodiment or in addition, each substrate 3 can itself be coated with an adhesive, which can optionally be protected by a protective film (not shown). )

As shown in FIG. 8, the user assembles the substrate 3 on the support 2 before use, reconfigures the patch 1, then wets the patch 1, and the active agent 3 contained in the substrate 3. To act on the lips.
In a particular embodiment, the adhesive used has a sufficiently low adhesive strength so that the support 2 can be separated from the substrate 3 after use and the support 2 can be reused with two new substrates 3. Like that.

As shown in FIG. 10, the patch 1 can include a handle portion 20.
This handle portion 20 can be used, for example, for the user to grab the patch 1 between the thumb and forefinger and to bring it to the lips and to remove it from the lips.
According to an example, the handle portion 20 is cut along with the rest of the patch 1.

  In essence, the present invention is not limited to the embodiments described above. Other examples without a handle portion can be formed. Specifically, the support can be changed. For example, the support can be formed using a composite structure. The support can include at least one active agent to act on the lips, where appropriate.

  In the above description, including the claims, the term “including one” is to be understood as a synonym for “including at least one”, unless the contrary meaning is specified.
