Description

Wearable beauty mask

Technical Field

The present invention relates to a skin care product, and more particularly, to a wearable mask that a user can wear to ensure that cosmetic ingredients contact the user's facial skin.

The invention also relates to a method for packaging the cosmetic mask and to a method for applying the cosmetic mask to the skin surface to be treated.

Background

Cosmetic masks are often used to apply cosmetic ingredients to the skin surface of a user, particularly the face. An example of such a mask is described in patent application US2016227905a 1.

According to the present application, cosmetic product or cosmetic ingredient is understood to mean the product defined in european council and conference regulation 1223/2009 on days 11, 30 of 2009 for cosmetic products.

Cosmetic masks typically include a sheet substrate impregnated with a cosmetic composition. The cosmetic ingredient may be, for example, a cream, a lotion or even a gel, in particular a hydrogel.

The cosmetic component may be, for example, a skin-care component, a moisturizing component, a whitening component, an anti-aging component, or the like.

Depending on the mask material, wearable masks that do not contain cosmetic ingredients may also be used, for example, to adsorb excess skin oil or sebum.

Various materials may be used for the substrate sheet depending on the desired infusion/release characteristics and/or cosmetic properties.

The substrate may be made, for example, from a woven or nonwoven fabric or mesh. The fabric can in particular be made of natural or synthetic fibers, such as cellulose fibers, polypropylene or polyethylene or nylon fibers, or of a mixture of various fibers. The substrate sheet may also be made of a thin paper or foil or film material, or even a thin layer of a foam or elastomeric material. Wherein the substrate sheet may have occlusive or permeable properties, in particular with respect to water and/or air.

The substrate may also comprise only one layer or be made of several layers, preferably made of different materials.

The substrate sheet is sized and shaped to cover a target skin surface of a user. In particular, for a mask, the substrate sheet will also include openings corresponding to the mouth, nose and eyes of the user.

When referring to a mask, the orientation should be considered with respect to the skin surface to be treated. Thus, for a mask, the top portion of the mask will be the portion of the mask intended to be positioned over the eyes, substantially on the forehead of the user. Likewise, the lateral portions or sides of the mask will be the portions intended to be positioned around the nose, substantially over the cheeks of the user. The left-right direction should be understood from the user's perspective.

In order to protect the cosmetic ingredients, the impregnated mask is usually packaged individually in a folded state, usually in a pouch.

When the mask is used, the folded sheet is removed from the package and then unfolded prior to application to the skin surface to ensure that the cosmetic composition contacts the skin surface.

Due to the cosmetic ingredients, the folded substrate sheet is very wet and/or sticky and it is often difficult to manipulate and unfold the sheet with the fingers.

In particular, it may be difficult to find the edge of the folded sheet, and thus the user may take time to find the edge to be maintained. In addition, it may be difficult for a user to maintain a wet edge that may easily curl or bend. In addition, wet sheets can easily tear, thus requiring careful handling.

In addition, during the unfolding process, a portion of the spread sheet may spontaneously curl or bend in the air and adhere to another portion of the sheet. If so, applying the patch to the skin becomes more difficult because the curled or bent portions must be unrolled while retaining the rest of the patch.

Furthermore, since the user must directly touch and manipulate the mask, the user may soil his hands and fingers with some products during manipulation and positioning.

To address this problem, the substrate sheet may include laterally projecting tabs, such as disclosed in US 6702792.

To further facilitate the unfolding of the mask, it is also known to fold the substrate sheet according to some particular folding method, including folding the substrate sheet along several fold lines. For an example of the folding method, reference may be made to patent application PCT/JP 2011/070308.

Furthermore, a cosmetic mask is intended to remain on the skin for at least one minute, preferably several minutes or even more than ten minutes, in contrast to a wipe which is not intended to remain in contact with the skin for a longer period of time.

It is therefore crucial that the user correctly positions the mask so that the skin surface to be treated is correctly covered.

This is particularly difficult for masks where the user must position the mask on his face, taking into account his eyes and nose, in order for the mask to be correctly positioned on his forehead, cheeks and other areas to be treated.

Although mouth, nose and eye apertures help to correctly position the mask for a mask, there is still a need for a solution that allows for easier and more comfortable handling and application of such cosmetic masks.

One solution is to package the mask in a rolled up state rather than a folded state. More specifically, the substrate sheet is rolled or wound on a horizontal bar (i.e., a bar intended to be positioned horizontally across the user's face when the mask is applied).

Korean patents KR101684594 and KR101684595 describe such masks and corresponding application methods.

When such a rolled mask is used, the mask is removed from the package in a rolled state. The rolled mask has a protruding tab that the user positions and holds by his finger on top of his forehead.

The user then spreads the mask vertically down by moving the bar towards his chin, just like a curtain.

Although the handling of the mask is improved, this solution is still not ideal, since the positioning is still uncertain.

In fact, because the position of the eyes, nose and mouth is not visible to the user before the mask is rolled out, the user cannot know exactly where to position the top tab on his forehead, so when the mask is rolled out, the aperture may be positioned too low or too high, which may force the user to reposition the cosmetic mask.

It is also important to note that the mask is not attached to the wand so that the mask may be easily loosened after being rolled out and the wand then discarded. Because the substrate base is not attached to the rod, initial rolling of the mask to package the mask is not easy, especially from an industrial standpoint.

Disclosure of Invention

The present invention aims to solve at least part of the above problems.

The above objects of the present invention are achieved by a wearable mask comprising a mask body formed from a flexible sheet substrate, said mask being deployable from a packaging configuration to a wearable configuration, the mask comprising a holding means at least in its packaging configuration, the holding means comprising at least one rod around which the mask body is at least partially rolled up, said mask being characterized in that the mask body comprises a peripheral edge from which the mask body is rolled up onto the rod and is removably attached to said rod.

By "flexible" is meant that the mask body is sufficiently compliant and can bend to roll around the rod.

By removably attaching the mask body to the rod, it limits the risk of the mask body accidentally separating from the rod before the unrolling is complete.

In addition, the mask body is better positioned and more easily rolled around the rod during the packaging operation. The packaging operation is thus greatly improved.

The rod may have various shapes, although a cylindrical shape is preferred, a polygonal shape may facilitate handling and unrolling. The rod may be hollow, like a straw, or solid.

The diameter of the rod may be comprised between 3mm and about 20 mm.

As disclosed in the above-cited korean patent, the sticks may include a handle bar on which the corresponding stick can freely rotate.

The attachment strength should be determined such that at the end of unrolling, the mask body is easily detached from the rod with a slight additional traction by the user.

Preferably, the peripheral edge is a wing or tab that protrudes from the central portion of the mask body. The projecting tongue or wing thus constitutes a dedicated part intended to be attached specifically to the stick. The main central portion of the mask body can therefore be dedicated to cosmetic treatment.

Advantageously, the mask body is removably attached to the rod at part of its peripheral attachment area, the mask body being loosely wrapped around the remainder of the rod's periphery. By providing a limited dedicated attachment area on the wand, the attachment force is easier to control and does not interfere with the unrolling process. There is no specific retention force on the rest of the circumference of the rod.

Preferably, the mask is removably attached to the wand at an attachment area of the wand, the attachment area extending in a substantially longitudinal direction of the wand. In short, the attachment region forms an attachment longitudinal strip or band extending along the rod. The attachment portion may extend along a portion of the rod or over the entire length of the rod.

The corresponding attachment portion (peripheral edge) on the mask body may be shorter than the attachment portion on the bar.

Various ways of attaching the mask body to the bar can be considered. Several options will be described below. Each option may be implemented individually or in combination.

According to a first variant, the mask body is removably attached to the rod by means of an adhesive material which is locally present on the attachment area of the rod.

The mask body may for example be slightly glued to the rod, i.e. by means of an adhesive material (e.g. like glue for adhesive paper strips) which is locally applied to the rod, for example along a longitudinal line of the rod.

According to a second variant, the mask body is removably attached to the rod by a punched hole through the mask body and leading to the rod.

For punching the holes, the rods should preferably be hollow.

Punching a hole through the mask body creates a small residual tab that will help hold the mask body on the rod with increased friction. However, the mask body will still be easily detachable.

Preferably, the mask body is at least partially melted at the punched hole. In other words, the stamping may be assisted by heating to at least partially melt the base material of the mask body. Partially melting the material at the punched hole will increase the interaction with the rod. The temperature may be comprised between, for example, 160 ℃ and 220 ℃ depending on the material of the mask body.

According to a third variant, the bar shows a slit extending along the longitudinal direction of the bar, into which the peripheral edge portion of the mask body is inserted.

The slits will contribute to additional retention of the mask body, especially when rolling and unrolling the mask, but at the end of unrolling the mask will be easily withdrawn from the slits.

Preferably, the slit is configured to be elastically clamped on the insertion portion of the mask body.

According to a fourth variant, the mask body is removably attached to the bar by bristles that protrude from the attachment area of the bar and act like scratch strips that interact with the mask body.

The bristles or tines will act like scratch tapes and interact with the substrate sheet, especially when the substrate sheet is fiber based, to cause friction and help hold the mask body slightly on the stick. Preferably, the bristles or tines are arranged partially along the longitudinal line of the respective bar and do not cover all of the circumference of the bar.

According to a preferred embodiment, the holding means comprise two lateral vertical bars onto which the mask body is rolled up.

By "vertical" it is meant that the rod extends substantially along the height of the mask body, that is, as defined above, between the bottom and top portions of the mask, across the width of the mask body.

Likewise, "horizontal" refers to a width that substantially spans the mask body.

Rolling the mask around the two lateral vertical bars results in improved handling and positioning of the mask.

The rods are substantially vertical and the mask is more easily rolled out by simply spacing the rods laterally.

Providing two rods also aids in handling and positioning of the mask. Furthermore, because of the two rods, no additional projecting tabs are required to remain on the face when the mask is unfolded.

Advantageously, the mask body is rolled up substantially symmetrically around the two side bars. This means that a mask body of substantially the same width is rolled around each rod, the rods being substantially centered on the mask body on each side of a medial centerline of the mask body in a rolled package configuration.

This greatly facilitates the positioning of the mask as the user can simply position the mask in front of his face substantially at his nose line. Since the mask has been rolled up symmetrically, when the rods are spaced apart, substantially the same length of mask will be rolled out on each side of the face.

According to an alternative embodiment, the retaining means comprises at least one horizontal bar, preferably located at the bottom edge of the mask body when rolled out.

Preferably, the length of the rods is such that they protrude at least from the border (top/bottom or lateral border, depending on the orientation of the rods). Preferably, the length of the rod is greater than the overall height or width of the mask, depending on the orientation of the rod. Having a protruding rod will dispose the free, non-rolled end of the rod so that the user can easily grasp the mask without touching the mask body.

Advantageously, the mask body, in particular the flexible sheet, comprises at least one shoulder or tab projecting from a central portion of the mask body and forming a lateral edge from which the mask is rolled up on the rod. By providing side flaps that are primarily intended or dedicated to attaching the mask body to the wand, this will maintain the major portion of the mask body (surface, integrity, etc.) that is intended to be in contact with the face. Attachment of the mask body occurs at the side flaps.

Preferably, the mask is rolled such that when rolled out, the rods are located on the outer surface of the mask body. By outer surface, it is meant a surface that is not intended to be in contact with the skin, as opposed to the opposite inner surface of the mask body which is intended to be applied directly to the face.

By rolling the rod on the outer surface of the mask, it is easier for the user to position his hands to space the rod and spread the mask open.

In particular, when the holding device comprises a lateral vertical bar, the user can bring his elbows close to the chest and grasp the bar behind the mask, and then easily pull his arms apart to spread the mask.

Of course, the stick may be rolled on the opposite inner surface, but the user must pull open and flatten his elbow in order to be able to grip the stick inwards.

In a preferred embodiment, the mask body, particularly the substrate sheet, is impregnated with a cosmetic composition. The word "impregnated" is intended to cover both the case where the cosmetic composition actually penetrates into the substrate sheet material (e.g. porous and/or fibrous material) and the case where the cosmetic composition actually forms a constituent layer on the substrate sheet (e.g. film and/or occlusive material) and at least partially covers the mask body.

The cosmetic ingredient substrate may be a cream or lotion or even a gel, in particular a hydrogel.

Detailed Description

Fig. 1 to 3 show a wearable mask 1 according to the present application.

The mask 1 includes a mask body 2 formed of a flexible sheet substrate.

The substrate sheet may be made, for example, of a woven or non-woven fabric or mesh. The fabric can in particular be made of natural or synthetic fibers, such as cellulose fibers, polypropylene or polyethylene or nylon fibers, or of a mixture of various fibers. The substrate sheet may also be made of a thin paper or foil or film material, or even a thin layer of a foam or elastomeric material. Wherein the substrate sheet may have occlusive or permeable properties, in particular with respect to water and/or air.

The substrate sheet is sized and shaped to substantially cover a target skin surface of a user. In particular, for a mask, the base sheet will also include openings corresponding to the mouth 3a, nose 3b and eyes 3c of the user.

More specifically, the nose opening 3b is made of a cut leaving a flap that will be pushed away by the nose of the user when the mask is applied.

The mask body also includes two lateral edges 6 or wings extending laterally from a main central portion 7 of the mask body 2.

The mask body 2 includes an inner surface intended for application on the face of a user and contact with the skin, and an opposite outer surface intended for facing away from the face of the user when the mask is positioned.

Preferably, at least the inner surface is at least partially covered and/or impregnated with cosmetic ingredients. The cosmetic composition may be, for example, a lotion, cream or gel.

The mask 1 is deployable from a packaging configuration (fig. 1) to a wearable configuration (fig. 3). Fig. 2 shows the mask 1 in an intermediate configuration.

According to the present application, the mask 1 comprises a holding device comprising two lateral vertical bars 5.

As shown in fig. 1, in the packaging configuration, the mask body 2 is rolled up onto each lateral rod 5.

The rod 5 is substantially cylindrical. The rod 5 is hollow, like a straw (fig. 11). The diameter of the rod 5 is preferably comprised between 0.3cm and 1 cm.

The rod is made of a plastic material, such as polypropylene and/or polyethylene. Preferably, the length of the bar 5 is substantially equal to the maximum height of the mask body 2. The rods 5 are also longer than the height of the side flaps 6 so that they protrude from the mask body 2 at the side flaps 6.

Fig. 4 is a transverse top view of the mask 1 showing how the mask body 2 is rolled onto each rod 5.

The mask body 2 is rolled inward from the wings 6 to the center of the mask body 2.

The rod 5 is positioned and rolled on the outer surface of the mask body 2.

More specifically, when packaged, the mask body 2 is arranged in a substantially flat, unfolded configuration.

The rod 5 is then positioned vertically at each lateral edge portion or wing 6 of the mask body 2.

When packaged, the rod 5 may simply be loosely positioned on the wings, or removably attached to the mask body 2, in particular to the side edges, in this case to the wings 6, prior to rolling. Various ways of attaching the rod 5 to the mask body 2 will be described below.

The rods 5 are then rolled inwardly with the mask body 2 so as to roll a significant portion of the mask body 2 around the respective lateral rods 5.

The rod 5 is rolled inward according to the substantially transverse direction of the mask 1.

The mask body 2 is rolled up substantially symmetrically around the two side bars 5. This results in the mask body 2 having substantially the same width being rolled up on the left and right sticks. Preferably, the lateral bars 5 are simultaneously wound up at a similar winding-up speed.

This also results in the stick 5 being located substantially in the centre of the mask body on each side of the centre line of the mask body 2 in the rolled up packaging configuration.

Fig. 5 to 8 show how the mask 1 can be easily applied on the face of a user.

The wearable mask 1 is initially stored in its packaged configuration in a pouch 7 (fig. 5).

The user opens the pouch 7 (fig. 6). To this end, the pouch 7 includes a top notch 8 that the user should tear to open the top end of the pouch.

The user should then remove the mask 1 from the pouch 7. To facilitate removal of the mask 1 from the pouch 7, the mask can be provided with a small protruding top tab that the user can grasp between the fingers before pulling the mask 1 out of the pouch 7.

The user then holds the mask 1 in its packaged configuration at the wand 5 and positions it in front of his face along a substantially vertical reference line.

In particular, since the mask 1 is rolled up symmetrically around each of the rods 5, the reference line is substantially the midline of the user's face, particularly the nasal line.

To deploy and apply the mask 1, the user pulls the rods 5 laterally to space them from each other and from the reference line and spreads the mask into its wearable configuration (fig. 7 and 8).

Since the mask 1 has been rolled up on the outer surface, the user holds the stick from the back of the mask 1, and it is easier for the user to position his hand to space the stick and spread the mask 1. In this way, the user can hold his elbows close to his chest and grasp a bar behind or behind the mask 1 and then easily pull his arms apart to spread the mask 1.

Once deployed (wearable configuration), the user may simply apply the mask 1 to his face.

The rod 5 is then removed from the mask body 2.

If the mask 1 has been rolled loosely on the rod 5, the rod 5 will simply be removed from the mask body 2 at the end of unrolling.

If the mask 1 has been rolled up by pre-attaching the side edges to the rod 5, the user may need to apply a slight additional traction force in order to detach the rod from the mask body 2.

As described above, attaching the mask body 2 to the rod will facilitate the rolling operation for packaging the mask.

The attachment strength should be determined so that the mask body 2 can be easily detached from the rod 5 at the end of unrolling under a slight additional traction of the user.

According to a first embodiment (not shown), the mask body 2 can be, for example, glued slightly to the rod 5, i.e. by means of an adhesive material applied locally on the rod. The local tackiness of the stick will provide additional friction that will help hold the mask body 2 on the stick 5. For example, a light weight glue may be used, such as a glue for a removable adhesive strip.

According to a second preferred embodiment, as shown in fig. 9 and 10, the mask body 2 can also be attached to the rods 5 by punching holes 10 made through the mask body 2 and the respective rods 5. The punched holes may advantageously be arranged along a longitudinal line of the rod 5. The number of holes punched through the mask body 2 depends on the desired holding force. As shown in fig. 9 and 10, three holes have been punched. More generally, the number of holes should be between two and ten. The diameter of the punched hole may be between 0.3mm and 0.5 mm.

When the hole 10 is punched through the mask body 2 and the rod 5, this will result in a small residual flap from the mask which will bend through the hole 10 on the rod 5 towards the inside of the rod 5.

The tabs (not visible) will help to hold the mask body 2 on the rod 5 by increased friction. However, the mask body 2 will still be easily detachable.

During or after the stamping, the stamping may be assisted by heat (e.g. between 160 ℃ and 220 ℃) in order to slightly melt the material of the mask body and increase the interaction with the material of the rod 5.

Another possibility is to use a bar 5 comprising a longitudinal slit 11 (fig. 12) into which the respective end portions of the side edges of the mask body 2 are introduced.

The slit 11 may extend over the entire length of the rod 5 or only over a part of the length of the rod 5, preferably the central part.

The slit 11 will provide additional retention of the mask body 11 in the rolled up direction. However, once spread, the mask is easily removed from the slit 11.

Advantageously, the slits 11 are resilient and the rod 5 is configured such that the slits 11 can grip or clamp the mask body 2. When assembled and packaged, the slit 11 will open slightly and portions of the side edges of the mask body 2 will be inserted through the slit 11. Upon release, the slit 11 will clamp onto the mask body 2 and improve the holding force.

Fig. 10 and 12 show other types of rods 5, respectively, namely hollow rods, such as suction tubes, and ordinary solid rods that can also be used to roll up the mask body 2.

Fig. 14 and 15 are illustrations of a wand 5 with protruding bristles 15 to help removably retain the mask body 2 on the wand.

Bristles 15 or tines protrude from the surface of the wand 5. The bristles or tines will act like a scratch strip and interact with the mask body 2 to cause friction and help hold the mask body 2 slightly on the stick. Preferably, the bristles or tines are arranged locally along the longitudinal line of the respective bar and do not cover all of the circumference of the bar.

It is important to note that each of the disclosed ways of slightly attaching the mask body 2 to the rod can be accomplished individually or in combination, depending on the desired holding force. Furthermore, none of the disclosed ways of slightly attaching the mask body 2 to a rod is limited to a holding device comprising two lateral rods and may be used in a holding device for a mask having only one rod that is rolled up from the side or top or bottom of the mask body.
