Description

  The present invention relates to a skin cleaning sheet with good foaming and less physical irritation, for example, for removing foundations, lipsticks, etc. from the face, or for cleaning the wound surface and surrounding skin, etc. It can be used suitably.

  Foaming detergents form fine bubbles when used in a well-foamed state, but it is said that this fine foam penetrates into dirt deposits (for example, into the pores of the face), thus increasing the cleaning effect. Yes. In addition, since fine bubbles are easier to rinse out and easier to rinse, it is recommended to sufficiently foam until fine elastic bubbles are formed because the burden on the skin can be avoided. However, since it takes time to finely and finely foam only with palms and fingers, foaming sponges, puffs, nets, cloths, etc. are commercially available. These foaming products are soaked with a cleaning agent and thoroughly mixed by hand to mix and agitate the air, water, and the cleaning agent so that fine meringue-like bubbles are formed. After the foam is formed, the foam is picked up and the face is washed with fingers, but the face and body can be washed with the foaming product itself (for example, sponge or the like). Usually, these whipping products are not disposable, and can be used repeatedly by thoroughly washing the whipping products with water after use. However, when foundations or the like that are oily stains are adsorbed on the foaming product, they are difficult to remove even after washing, and therefore, disposable foaming products have been desired.

  For example, Patent Document 1 proposes a nonwoven fabric in which hydrophilic fibers, hydrophobic fibers, and hydrophobic adhesive fibers are entangled by a hydroentanglement method. This non-woven fabric for skin cleaning secures retention of the water-based cleaning agent with hydrophilic fibers and secures form stability when wet and rebound of the nonwoven fabric with hydrophobic fibers to enhance foaming properties. However, this non-woven fabric for skin cleaning is intended to foam by squeezing with both hands or putting a non-woven fabric in one hand and holding or opening the palm. It was difficult to make and there was room for improvement in the cleaning effect.

On the other hand, in order to wipe the wound surface such as pressure ulcer and the surrounding skin, non-woven fabric softer than conventional cotton gauze for medical use has been used. These gauze and non-woven fabrics are convenient to dispose of because germs and the like adhere to them during wiping. And the disposable skin-cleaning sheet | seat which can be utilized when wiping off using an aqueous cleaning agent is calculated | required. In this case, on the skin cleaning sheet, it is possible to quickly create fine bubbles, to create bubbles with the fingers of only one hand (if both hands are full of bubbles, it is difficult to clean) It must be flexible enough to enter. However, the nonwoven fabric for skin cleaning described in Patent Document 1 is not configured to produce fine bubbles with only one finger, so a large area nonwoven fabric and a large amount of labor are required to obtain sufficient foaming. Met.
JP 2003-38381 A

  Therefore, the present invention can make fine bubbles quickly with just one finger, and can clean and wipe the skin with only one hand at the same time as foaming, and also has small areas such as between small areas of skin and wrinkles. Providing a skin cleansing sheet that can be wiped off reliably was raised as an issue.

  In the skin cleaning sheet of the present invention, a plurality of non-woven fabrics are overlapped, and a connecting portion for connecting these non-woven fabrics is provided. In addition to this connecting portion, adjacent non-woven fabrics are configured to be slidable. It has a feature in some places. The connecting portion preferably has a linear shape, a dot shape, a planar shape, a lattice shape, or a combination thereof. Moreover, the structure whose sheet | seat for skin washing | cleaning is a substantially rectangular shape of width 20-100mm and length 50-200mm is one embodiment of this invention.

  The connecting portion may connect one end edge of the two edges of the overlapping nonwoven fabrics in the width direction or the longitudinal direction. When the connecting portion is substantially the same as the length of the skin cleaning sheet, the skin cleaning sheet folded so that the side view is substantially V-shaped, or the side view is substantially W-shaped. A folded skin cleaning sheet can be easily obtained.

  The said connection part may connect all the nonwoven fabrics piled up in the thickness direction. If it is this structure, since the laminated nonwoven fabric is firmly fixed by a connection part, it is excellent in the form retainability during foaming.

  It is preferable that the nonwoven fabric has at least a three-layer structure having an intermediate layer made of hydrophilic fibers and a surface layer and a back layer made of hydrophobic fibers. The middle hydrophilic fiber intermediate layer keeps moisture and water-based detergent well, and the hydrophobic fiber front and back layers repel even when wet and prevent curling. During foaming, the water-based detergent contained in the hydrophilic fiber intermediate layer is mixed with the air between the hydrophobic fibers when passing through the surface layer and the back layer made of hydrophobic fibers. Is even better.

  In the skin cleaning sheet according to the present invention, the nonwoven fabrics are slidably laminated, and the overlapped nonwoven fabrics are connected to each other at the connecting portion. Fine bubbles can be made quickly just by rubbing and performing a foaming operation (sliding operation). Further, the presence of the connecting portion prevents the nonwoven fabric of each layer from falling apart during cleaning and wiping, and the sheet has excellent shape stability. Since the sliding operation is possible only with the finger of one hand, it is not necessary to wet the hands that do not lather, and other operations can be performed freely. Furthermore, since it is made of an inexpensive non-woven fabric, it can be disposable.

  Hereinafter, the skin cleaning sheet according to the present invention will be specifically described with reference to the drawings showing examples. However, the present invention is not limited to the illustrated examples, and may conform to the gist of the preceding and following descriptions. It is of course possible to carry out the present invention with appropriate modifications within the scope, and these are all included in the technical scope of the present invention.

  FIG. 1 (a) is a perspective explanatory view showing a skin cleaning sheet 1a according to one embodiment of the present invention, and FIG. 1 (b) is a perspective explanatory view showing a skin cleaning sheet 1b according to another embodiment. It is. In the skin cleaning sheet 1a, an upper nonwoven fabric 2-1 and a lower nonwoven fabric 2-2 are laminated, and the right edge in the longitudinal direction of the two upper and lower nonwoven fabrics 2-1 and 2-2 is the connecting portion 3. is there. That is, the skin cleaning sheet 1a has a substantially rectangular shape with a width L1 and a length L2 in a plan view and a substantially V shape in a side view. Non-woven fabrics 2-1 and 2-2 which are adjacent to each other in the upper and lower sides other than the connecting portion 3 are configured to be slidable (slidable portion 4). The connecting portion 3 can be formed as a fold line formed when a single nonwoven fabric is folded, or by joining one longitudinal end edge of two separate nonwoven fabrics. On the other hand, the skin cleaning sheet 1b is formed by laminating four layers of non-woven fabrics 2-1, 2-2, 2-3, 2-4, and has a substantially rectangular shape with a width L1 and a length L2 in plan view. Is formed in a substantially W shape. The connection part 3 is comprised so that the one end edge of the longitudinal direction of the nonwoven fabrics 2 which overlaps up and down may be joined alternately right and left. That is, in the nonwoven fabric 2-1 of the uppermost layer and the nonwoven fabric 2-2 in the lower layer, the right end edge becomes the connecting portion 3, and in the nonwoven fabrics 2-2 and 2-3, the left end edge becomes the connecting portion 3, and the nonwoven fabrics 2-3 and 2 In -4, the right end edge is the connecting portion 3. The connecting portion 3 may be a folded portion formed when one nonwoven fabric is folded, and is formed by alternately joining one end edge of two overlapping nonwoven fabrics on the left and right sides of the four nonwoven fabrics. It may be done.

  In the skin cleaning sheet 1a or 1b, since the connecting portion 3 is formed only at one end of the nonwoven fabric, there is an advantage that the area of the slidable portion 4 of the nonwoven fabric can be increased and the foaming operation can be facilitated. Moreover, manufacture is also easy. In each of the above-mentioned skin cleaning sheets 1a or 1b, the width L1 is preferably about 20 to 100 mm, and the length L2 is about 50 to 200 mm because it is easy to handle with one hand.

  In the skin cleaning sheet of the present invention, the connecting portion may connect all the laminated nonwoven fabrics in the thickness direction. For example, FIG. 2 (a) shows a plan view of a skin cleaning sheet 1c provided with dotted connecting portions 3 on both side edges, and FIG. 2 (b) shows a perspective view thereof. As can be seen from the perspective view, this skin cleaning sheet 1c is composed of three nonwoven fabrics 2-1, 2-2, 2-3, and dotted connection parts 3, 3 are formed in the vicinity of both left and right edges. Is provided. The connecting portion 3 connects three nonwoven fabrics in the thickness direction, and the nonwoven fabric between the left and right connecting portions 3 is a slidable portion 4. Of course, any number of laminated nonwoven fabrics may be used.

  Further, FIG. 3A shows a skin cleaning sheet 1d having a dot-like connecting portion 3, and FIG. 3B shows a skin cleaning sheet 1e having a rough grid-like connecting portion 3. It is preferable that these connection parts 3 also connect all the laminated nonwoven fabrics in the thickness direction. In the skin cleaning sheet 1d, the non-woven fabric other than being restrained by the dot-like connecting portions 3 is the slidable portion 4, and in the skin cleaning sheet 1e, the grids (lattices) of the grid-like connecting portions 3 are used. Inside and around the grid are slidable portions 4.

  In the skin cleaning sheets 1c to 1e having a connecting portion for connecting all the laminated nonwoven fabrics in the thickness direction, the connecting portion firmly restrains the nonwoven fabric of each layer. The nonwoven fabric of each layer does not fall apart and is excellent in form stability as a sheet.

  In each of the skin cleaning sheets 1c to 1e, the width is preferably about 20 to 100 mm, and the length is preferably about 50 to 200 mm. Note that the shape of the skin cleaning sheet is not particularly limited to a rectangular shape or a square shape, and may be appropriately modified depending on the application, such as a circular shape, an oval shape, an hourglass shape, and a battledore shape. Further, the number of laminated nonwoven fabrics is not particularly limited as long as it is 2 or more. However, when the thickness of the skin cleaning sheet becomes too thick, it becomes difficult to perform a sliding operation, so about 10 sheets or less, more preferably about 5 sheets or less. It is good to keep it down.

  As a specific foaming method, a detergent and, if necessary, water are soaked into the slidable portion 4 of the skin cleaning sheet, and an index finger (middle finger, ring finger, and little finger if necessary) is placed under the sheet, The upper and lower non-woven fabrics are slid to each other so that the belly of these fingers are rubbed together, and the cleaning agent and air may be mixed using the gaps between the non-woven fabric fibers. Since the skin cleaning sheet of the present invention has a shape and shape stability suitable for cleaning, the skin cleaning and wiping can be started immediately after foaming sufficiently.

  Nonwoven fabrics that can be used for the skin cleaning sheet of the present invention can be made of polyolefins such as polyethylene and polypropylene, hydrophobic fibers such as polyester and acrylic, and nonwoven fabrics made of hydrophilic fibers such as rayon, cotton, and acetate. . Those using these composite fibers, mixed fiber nonwoven fabrics and the like can also be used. Examples of the manufacturing method include nonwoven fabrics obtained by various manufacturing methods such as spunbond, melt blow, SMS, thermal bond, and spun lace (hydroentanglement). In order to make finer bubbles, it is desirable that the constituent fibers of the nonwoven fabric are thin, and it is more preferable to use split fibers.

  The non-woven fabric may have a single-layer structure, but the non-woven fabric having a three-layer structure in which the hydrophilic fiber intermediate layer is sandwiched between the hydrophobic fiber surface layer and the back layer is one of the constituent materials of the skin cleaning sheet. It is preferable to use as part or all. The cleaning agent dripped onto the skin cleaning sheet quickly soaks into the intermediate layer made of hydrophilic fibers and passes between the fibers while passing through the hydrophobic fibrous surface layer and back layer during sliding operation (foaming operation). This is because fine bubbles are rapidly formed by being mixed with air in the voids.

  In particular, when rayon fiber is used as the hydrophilic fiber of the intermediate layer having the three-layer structure, the skin cleansing sheet becomes flexible, which is preferable. Moreover, as a hydrophobic fiber of a surface layer or a back layer, the said polyethylene fiber, a polypropylene fiber, and an acrylic fiber are preferable.

The nonwoven fabric preferably has a weight per unit area of 10 to 60 g / m ² (more preferably 20 to 50 g / m ² ) in any nonwoven fabric having a single layer structure or a multilayer structure. In addition, the nonwoven fabric of each layer in the skin cleaning sheet may be the same material / configuration or a different material / configuration.

  The skin cleaning sheet of the present invention can quickly form fine bubbles and can be used for makeup removal. Further, since it can be easily foamed with one hand and is disposable, it is also useful as a medical skin cleansing sheet for wiping the wound surface such as pressure ulcer and the surrounding skin.
