Description

TECHNICAL FIELD

[0001] The utility model relates to a mask, concretely relates to a multifunctional invisible mask. BACKGROUND

[0002] There are four types of masks, including mud paste type, tearing type, frozen gel type and wet paper towel type. The wet paper towel type mask is favored by the public because of its convenience and simple operation. The wet paper towel type mask is coated on the face with non-woven fabric substrate supplemented by nutritional ingredients and drugs. In the short time of covering the face, the moisture and nutrients in the mask penetrate into the stratum corneum of the epidermis, making the skin soft and elastic. However, this type of mask has the following problems: (1) affects the experience. The mask is soaked in nutrient solution, and it is inevitable that the nutrient solution will drip during taking out or applying. Especially during the application process, the sticky nutrient solution will affect the experience whether it drips on the clothes or the skin. (2) There is a safety hazard. The nutrient solution contains a large amount of nutrients, which can easily rot or breed bacteria even after sterilization, resulting in a safety hazard. In order to prevent the breeding of bacteria, preservatives are usually added. (3) Poor fit. Because the fiber fineness of the non-woven fabric is thick, the thickness of the non-woven fabric is large, and even by pressing the mask, it cannot completely fit the face, resulting in that the nutrient solution cannot reach the eye corner, chin and wrinkle-prone areas. (4) Limited use time. The use time of the wet paper towel type mask should not be too long each time, usually not more than 20 minutes. If the time is too long, the mask will absorb the moisture in the skin after drying. (5) Limited use occasions. The wet paper towel type mask covers the face during use, and the thickness is thick, so it is difficult not to attract attention during use, and the use occasions are severely limited. (6) Wasteful and increases cost. The mask is stored in the nutrient solution, and there is often an excess of nutrient solution stored in the packaging bag, which is wasteful and increases cost. Liquid packaging needs to prevent the packaging bag from being punctured, which is not conducive to transportation and storage and also increases packaging cost.

[0003] In order to solve the problem of nutrient solution dripping, poor fit, inconvenience of use and unsuitability for multiple occasions, and to avoid bacterial breeding and improve skin care effect, Chinese patent 202321909835.X discloses an invisible mask suitable for multiple occasions. The invisible mask suitable for multiple occasions includes a substrate layer and a nanofiber film layer. The nanofiber film layer is formed on the substrate layer by electrospinning. However, due to the high requirements of electrospinning on the formula of the spinning solution, the invisible mask has certain limitations in meeting the functional customization needs of different groups of people such as whitening, anti-wrinkle and sun protection. However, when the mask is used as an eye patch, a nose patch, a foot patch, a skin blemish patch, a chin patch, a neck patch, a forehead patch, a marionette line patch, etc., it often has higher requirements for certain functions, but at the same time it is desired to maintain the original transparent property suitable for multiple occasions.

The microcapsule particle size of the functional layer is larger than the nanofiber fineness and the inter-fiber pore size in the nanofiber film layer, but is much smaller than the inter-fiber pore size in the substrate layer, so the microcapsule skin care agent can be blocked outside the nanofiber film layer from the protective layer and the substrate layer, and the functional layer is formed on the nanofiber film layer.
