Disclosure of Invention

The invention aims to provide a subarea care type facial mask adopting a single-layer integrated membrane cloth and a preparation method thereof.

In order to achieve the above object, in one aspect, the present invention further provides a single-layer integrated type zoned-treatment facial mask, wherein the zoned-treatment facial mask adopts a single-layer integrated type mask cloth, and two or more zones are included on the mask cloth of one facial mask, and each zone is coated with a different efficacy of a treatment solution composition.

In the mask of the present invention, the solution composition used is a composition containing one or more skin care ingredients, such as various essences, skin moisturizing ingredients, whitening ingredients, wrinkle-removing ingredients, tightening ingredients, and the like. Preferably, targeted, different compositions of the care solution are applied in zones directed to different locations of the face.

The mask disclosed by the invention can realize multiple nursing of one mask aiming at the skin problems at different positions of the face. All functional areas only take essence components with different efficacies as each functional area, and the membrane cloth as a carrier is only one piece, and the size of the membrane cloth occupies the whole face area. In the present invention, the main purpose of the segmentation is that the care required is different for different areas of the face.

For example, the inventors of the present application have found that a region of the face such as the forehead and nose is likely to secrete a large amount of fat and the like, and thus this partial region is defined as a central T-shaped region (region 1); accordingly, in the preparation process of the mask, the lotion composition having the effects of removing gloss, whitening, removing acne, removing wrinkles, etc. is applied to the area of the mask by a doctor blade.

The inventors of the present application have also found that a region such as the eye-tail of the face is likely to generate wrinkles and the like, and thus a partial region is defined as an eye-tail region (region 2); accordingly, in the preparation of the mask pack, a care solution composition having wrinkle removing, whitening, tightening, etc. effects is applied to the area of the mask pack by a doctor blade.

The inventors of the present application have also found that the lower eyelid and other regions of the face are prone to produce bags and dark circles, and thus define a partial region as the lower eyelid region (region 3); accordingly, in the preparation process of the mask, the care solution composition having the effects of removing dark eye circles, removing eye bags, tightening and the like is applied to the area of the mask by a doctor blade.

The inventors of the present application also found that the cheek and other regions of the face are prone to dryness and chapping, and the like, and thus a partial region is defined as the cheek C region (region 4); accordingly, in the preparation process of the mask, a care solution composition having moisturizing, whitening, tightening, etc. effects is applied to the area of the mask by a doctor blade.

The inventor of the application further finds that the areas of the face, such as the lips and the lower jaw, are easy to dry, crack and peel, and are easy to itch when being exposed to wind, so that a partial area is defined as the area of the lips (area 5); accordingly, in the preparation process of the mask, the care solution composition having desensitizing, moisturizing, whitening, tightening, etc. effects is applied to the area of the mask by a doctor blade.

In the present invention, the face may be divided into the above five basic regions, or may be divided into more and finer regions, or may be divided into less regions, for example, 2 to 4 regions. How the partition is specific depends on the population of the consumer, the living area and environment, age, gender, and other factors. However, those skilled in the art will appreciate that such partition adjustment can be readily implemented in the present invention.

As a specific embodiment, in the present invention, the sections of the mask may include a central T-shaped area, an eye-tail area, a lower eyelid area, a cheek C area, and a double lip area, wherein each section is knife coated with a different efficacy of the treatment composition.

In the above mask, the mask cloth used may be a nonwoven cloth, and the adopted regions include a central T-shaped region, an eye-tail region, a lower eyelid region, a cheek C region, and a double-lip region.

In the facial mask, each section of the care solution composition is coated with a blade, and after drying, the gram weight of the care solution composition formed in the corresponding section is 8-50g/m²The care layer of (1).

Preferably, the zoned care mask of the present invention is a dry mask, and the lotion composition in each zone is air-dried, oven-dried at low temperature or lyophilized to remove moisture therefrom. This has the advantage that migration of components from different regions can be prevented.

On the other hand, in order to realize the aim of the invention, the invention also provides a process method for continuously preparing the partitioned nursing type facial mask of the integrated membrane cloth, wherein the adopted membrane cloth is a single layer, the partitioned partitions at least comprise two or more partitions, and each partition is coated with a corresponding nursing liquid composition aiming at the skin characteristic corresponding to the partition in a scraping way; the process method comprises the following steps:

(1) dividing the mask cloth of a mask into a plurality of subareas according to the characteristics of different skin areas of the face;

(2) each subarea is assigned to a corresponding scraping roller;

(3) applying the care solution composition to the corresponding subarea by each blade coating roller;

(4) when the film cloth continuously passes through the coating unit, the corresponding subareas are coated by the blade coating rollers in sequence;

wherein each blade coating roller is controlled to be immediately separated from contact with the membrane cloth after the coating of the corresponding subarea in one membrane is finished, and is contacted with the corresponding subarea when moving to the corresponding subarea of the next membrane.

In the above-mentioned process of the present invention, the liquid compositions used are directed and different liquid compositions for different areas of the face. Of course, in some cases, portions of the zones may be provided with the same treatment composition.

In the present invention, the solids content of the care solution composition is generally controlled to be 5% to 40%.

Preferably, in the above-mentioned process, the employed doctor blade roll is a magnetic doctor blade roll (or magnetic doctor blade roll), and the mesh number of the doctor blade roll is 60-200 mesh. The magnetic squeegee roller is a machine member which generates contact pressure to the printing screen under the action of electromagnetic force by using a squeegee steel roller and rolls on the screen surface for scraping. Generally, a set of electromagnet controlled by a cylinder is respectively arranged at the position corresponding to each screen frame below a rubber guide belt of an automatic flat screen printing machine, and the electromagnet reciprocates longitudinally of the fabric, so that a pulp scraping roller is driven to perform corresponding reciprocating rolling scraping printing on the flat screen surface; and an electromagnet is arranged below a rubber guide belt at the lowest part of each circular screen of the circular screen printing machine, so that a paste scraping roller in the circular screen is driven by the inner wall of the circular screen to roll, and simultaneously, the paste is extruded by the electromagnetic suction force and is transmitted to the fabric through the pattern mesh to be printed. Under normal conditions, the axial pressure of the pulp scraping roller is uniform, rolling friction exists between the pulp scraping roller and the screen, and the screen is less worn. The strength of the electromagnetic force and the diameter of the paste scraping roller are changed, so that the printing machine can adapt to the printing of various fabrics and different flower-shaped patterns and adjust the paste feeding amount of the scraping printing.

Further, in the above-mentioned process, the magnetic induction used during the blade coating is controlled to be 0 to 10 tesla, preferably 0.01 to 9 tesla, and more preferably 0.1 to 8 tesla. The advancing speed of the membrane cloth is 3-10 m/min.

In order to prevent migration of the ingredients in the lotion composition in each zone, the process of the present invention may further comprise a low temperature drying step to remove water from the lotion composition and thereby prevent migration of the ingredients, the low temperature drying step generally not exceeding 85 c, preferably between 60 and 80 c.

In addition, in order to prevent the loss of activity of the temperature-sensitive components in the care solution composition, the process method further comprises a freeze-drying step, wherein the freeze-drying temperature is between-30 ℃ and-50 ℃, and the vacuum degree is 15-60 Pa. The lyophilization process was about 10 hours. Lyophilization also achieves the effect of preventing migration of components of the partitioned treatment compositions.

Of course, a combination of low temperature drying and lyophilization process steps may also be used. For example, each temperature-insensitive care composition is first coated with a doctor blade roll and then oven-dried at low temperature; the temperature-sensitive care composition was then coated with a doctor blade and subsequently lyophilized.

According to the process of the present invention, after drying the draw down of the lotion composition, the grammage of each zone increases from 8 to 50g/m²。

In the process of the invention, each zone corresponds to a doctor blade roll; if the same care solution composition is used in a part of the regions, a doctor roll can be shared, and the coated region is the sum of the regions with the same efficacy.

In the process method, the mask is dried, blanked, completely freeze-dried, folded and bagged; or the facial mask can be directly dried and blanked at low temperature without freeze-drying process, and finally folded and bagged; or the facial mask is subjected to freeze-drying process only, and then is blanked, folded and bagged.

In fact, in addition to the above-described processes, the zone-care type mask of the present invention can also be prepared by other methods such as 3D printing, digital jet, and the like. However, from the viewpoint of cost, the process of the present invention is preferably employed.

It will be appreciated by those skilled in the art that a sheet of mask may be blanked into several portions during blanking, for example, the central T-shaped region may be blanked into one portion, the remainder may be blanked into another portion, and then packaged together or separately. Such an approach is still within the scope of the present invention.

In the invention, the membrane cloth or the base cloth of the facial mask can be non-woven cloth, including spunlace non-woven cloth and needle-punched non-woven cloth.

The facial mask and the preparation process thereof have the advantages that: 1. the trend of light, thin and transparent facial mask can be met; 2. each area exists in a dry state, so that the condition of mutual migration of functional components cannot occur, and the skin is nursed locally more thoroughly; 3. the facial mask has no antiseptic component, does not cause damage to skin, and belongs to a skin-friendly material; 4. the mask is simple and convenient to use; 5. the production process of the facial mask realizes automation to the maximum extent and can effectively reduce the production cost; 6. the automatic production process ensures the stable quality of the facial mask.
