Description

Wet sheet pillow packaging

technical field

The present invention relates to a wet sheet pillow package in which a liquid cosmetic, liquid medicine, or the like is impregnated in a fibrous raw material sheet such as a nonwoven fabric.

More specifically, the present invention relates to arranging and storing wet sheets such as wet wipes and mask sheets in a shallow tray horizontally, uniformly impregnating them with a predetermined amount of impregnating liquid up and down, and reversing the top and bottom surfaces during use. Therefore, the wet sheet pillow packaging body of the wet sheet can be taken out from the opening area at the bottom of the shallow pan connected to the take-out port of the pillow type packaging body.

Background technique

Conventionally, lotion has been used by impregnating a sheet of fibrous material such as woven cloth, non-woven fabric, gauze, cotton, etc. with lotion taken out of a container, and gently patting the face (patting). However, when used in this way, it takes time to impregnate the lotion on the sheet, and there are also problems such as the amount of lotion applied to the skin is too small, the feeling of use is poor, and the cosmetic effect cannot be obtained.

Therefore, wet wipes in which lotion is impregnated in advance on sheets of fibrous materials such as woven fabrics, nonwoven fabrics, gauze, and cotton are known, and various products that meet user needs are now available.

The impregnating solution is not limited to lotion, and is often used for hand and skin washing or disinfection by impregnating it with a chemical solution usually used for cleaning and disinfection.

Recently, wet sheets impregnated with liquid cosmetics such as wet wipes and sheet masks have been widely used, and are gradually being used for makeup removal, skin care, and the like.

Wet wipes used for washing and disinfecting hands and skin are mainly the following fixed products, that is, sheets that are stacked in the vertical or vertical direction after each sheet is folded, or sheets with folded cut lines formed according to the size of each sheet Sheets in a continuous state are stationary products that are stored in tens of sheets in cylindrical containers or box-shaped containers with outlets. However, there are also portable products that are folded and stacked vertically or vertically, in units of several to dozens of sheets, and stored in pillow-type packages with outlets, etc. Carrying goods in plastic film packaging.

Wet sheets used for makeup removal, skin care, etc., or impregnated with expensive liquid cosmetics, or increasing the amount of lotion impregnated in the sheet base material depending on the situation, may increase the cost. In order to increase the product value, each folded sheet is processed individually. Packages, or products packaged in units of a plurality of sheets are the main products, among which there are known products in which folded sheets are arranged vertically or vertically in units of a plurality and stored in a box-shaped container with emphasis on economy.

In this way, in order to meet various needs, wet sheet packages impregnated with liquid cosmetics, liquid medicines, etc. on fibrous raw material sheets such as woven fabrics, nonwoven fabrics, gauze, and cotton are distributed as daily necessities and cosmetics widely used.

Among the packaging of the above-mentioned wet sheets, the so-called flexible packaging, in which goods are packaged with plastic film, is widely used because it has many excellent advantages represented by economical efficiency.

One form of flexible packaging using this plastic film is typified by pillow packaging in which a packaging film is formed into a tube from a C shape and a product is packaged therein.

Pillow packaging is one of the most widely used packaging methods at present. Pillow (pillow)-shaped bags are used to package the products of the packaged objects. It is a horizontal pillow, which is called a vertical pillow when it is packaged vertically.

The pillow packaging is basically composed of the following parts, that is, a supply part for supplying a plastic film for packaging objects to be packaged, a forming part for forming the plastic film successively sent out from the supply part into a cylindrical shape, and filling the inside of the cylindrical plastic film. Loading part (conveyor belt) of the package, middle sealing part that heat-seals the edge parts of the cylindrical plastic film containing the packaged goods inside, drawing part that determines the cut size of the plastic film package after middle sealing, The sealing and cutting part that seals and cuts the tubular plastic film package whose cut size has been determined. The center seal is located in the center of the plastic film package, and the folded part of the plastic film forms the shape of the side of the package. packaging means (Non-Patent Document 1).

This kind of pillow packaging has the economy for the manufacturer that the process can be quickly packaged, the good portability of the obtained product, and the convenience of easy opening. Therefore, in the field of cosmetics, dry packaging has also been produced by using this packaging method. A large number of products such as wipes and wet sheets.

In particular, recently, a large number of wet sheet products impregnated with liquid cosmetics, such as wet wipes and mask sheets, have been formed to improve the moisturizing effect of the skin and impart moisture, etc. Regarding these wet sheets, in order to achieve a higher effect, it is necessary to impregnate a large amount of liquid Wet products of cosmetics.

For example, when impregnating a liquid cosmetic in a single-pack wet sheet package, if the economy of using an excessive amount of impregnating liquid is ignored, there will be no problem of uneven quality such as whether the amount of impregnation is uniform, but when using necessary liquid cosmetics in consideration of economy When the minimum amount of impregnating liquid is used, as in the past, when multiple wet sheets are stacked and stored in one direction (vertical or vertical direction in most cases) and packaged, there will be liquid cosmetics impregnated in each wet sheet. The impregnation amount near the bottom is high, and the impregnation amount near the top is insufficient. It is difficult to impregnate multiple wet sheets with a large amount of impregnation liquid evenly and effectively.

Conventionally, a wet sheet package (Patent Document 1) in which many folded wet sheets are arranged and stored in a horizontal direction and impregnated is a known package, but it is a container package as described below, and it is difficult to make the impregnation amount uniform, and it cannot be said that Wet sheet products with good economy and good impregnation rate like the invented pillow packaging.

Contents of the invention

As mentioned above, when providing a wet sheet impregnated with a large amount of liquid cosmetics, liquid medicine, etc. regardless of economic efficiency, it is necessary to make a sheet of fibrous material such as nonwoven fabric contact with a sufficient amount of liquid, so it is necessary to fill the container with liquid, and this Failed to achieve with pillow pack.

On the other hand, the packaging in the form of a container that can ensure a sufficient amount of liquid is not convenient, and it is easy to overpack, so it cannot be economical.

As the above-mentioned known wet sheet packaging body (patent document 1) of container form packaging, under the state that fibrous raw material sheets such as non-woven fabrics are folded, after it is mostly arranged and stored in the box-shaped container made of synthetic resin along the lateral direction, the container Wet sheet products that inject cosmetic liquid and impregnate the sheet are packaged in a box-shaped container made of synthetic resin, so it is an intermittent and laborious packaging method, and it is not easy and economical to obtain wet sheet products like pillow packaging. package body.

Therefore, an object of the present invention is to make the impregnation amount of the liquid cosmetic in the wet sheet uniform up and down even in a package form that stores a plurality of them at the same time, and to make it easy to take out the package of the wet sheet.

In order to solve the above-mentioned problems, the present invention basically features the following configurations.

(1) Wet sheet pillow packaging body, which is a pillow type packaging body for packaging a shallow tray containing wet sheets, characterized in that an opening corresponding to a wet sheet extraction port is formed approximately in the center of the bottom of the shallow tray The opening area is located at the plane part on the opposite side of the sealing surface of the pillow packaging body, and the wet sheet removal port is arranged on the plane part, and then the folded wet sheets are stored in multiple rows along the transverse direction in the shallow tray .

(2) The wet sheet pillow package according to the above (1), wherein the wet sheet is arranged and accommodated so that the folding line of the wet sheet is in contact with the bottom of the tray.

(3) The wet sheet pillow package according to the above (1) or (2), characterized in that the wet sheet can be opened and closed through the opening and closing cover provided on the flat surface opposite to the sealing surface, Take out one by one through the opening area of the platter and the take-out port of the flat part.

(4) The wet sheet pillow package according to any one of (1) to (3) above, characterized in that the main body of the opening area at the bottom of the shallow pan is formed by a convex embankment for accumulating the remaining impregnating liquid.

(5) The wet sheet pillow package according to any one of (1) to (4) above, wherein the liquid-impermeable sheet is interposed between wet sheets arranged in plural in the lateral direction in a tray. The gap between the sheet and the convex embankment.

(6) The wet sheet pillow package according to any one of (1) to (5) above, wherein the wet sheet is formed of a fibrous raw material sheet.

(7) The wet sheet pillow package according to any one of (1) to (6) above, wherein the wet sheet is impregnated with a liquid cosmetic or liquid medicine.

The wet sheet pillow package of the present invention is characterized in that when the wet sheet is taken out, the top surface and the bottom surface of the wet sheet pillow package are reversed.

That is, the wet sheet pillow package of the present invention is a wet sheet pillow package in which separately folded fibrous raw material sheets (also called wet sheets after impregnation) are arranged and accommodated in a reverse pillow type tray, Because the wet sheet take-out port provided on the flat surface opposite to the sealing surface of the pillow-type package communicates with the opening area for taking out the wet sheet arranged at the approximate center of the bottom of the shallow pan, so when taking out the wet sheet, the wet sheet can be taken out from the This removal port on the top side removes the wet sheet through the open area of the tray also on the top side.

In addition, in the present invention, the top surface means the side facing the sky or the upper side, and the bottom surface means the side facing the ground direction or the lower side.

Usually, pillow packaging has either positive pillow packaging or reverse pillow packaging. For pillow packaging of shallow trays with folded fiber raw material sheets, if positive pillow packaging is used, , there is no need to set an opening area at the bottom of the shallow tray, but the tapered upper part of the shallow tray will be located on the opposite side of the sealing surface of the pillow-type package. Opening and closing of the opening and closing cover installed in the outlet, or stacking of products may cause deformation and damage of the platter. On the other hand, when adopting the reverse pillow type packaging, as mentioned above, because the shallow tray bottom with strength is positioned at the plane portion where the wet sheet extraction port is provided, it has the advantage of not causing damage due to the opening and closing of the opening and closing cover and the stacking of products. The advantages of shallow plate deformation and damage caused by it.

The fibrous raw material sheets of the present invention are individually folded and stored in a plurality of rows in the horizontal direction in a tray, and the impregnating liquid injected in this state is impregnated from the upper part of the fibrous raw material sheets. Folding and arranging and storing of the fibrous raw material sheets may be performed without impregnating the impregnating liquid or after impregnating the impregnating liquid.

In addition, by arranging and storing the fibrous material sheets so that the folding lines of the sheets are in contact with the bottom of the tray, there is an advantage that the wet sheet stored in the pillow pack can be easily taken out and the stability on the tray is improved.

When forming a pillow package, the sealing surface is on the top side, but because the top surface and the bottom surface are reversed during use, the sealing surface becomes the bottom side, and the pillow package located on the top side is opened The opening and closing cover provided on the flat part of the tray can take out the wet sheet separately through the opening area in the approximate center of the bottom of the shallow dish (located on the top side when the top and bottom are reversed).

The roughly central opening area of the bottom of the shallow pan is divided by a convex bank, and this convex bank becomes a reservoir for the remaining impregnating liquid, so when the pillow package is formed, it is poured into the fibrous raw material sheets arranged and stored in the shallow pan The remaining liquid of the impregnating liquid is accumulated in the bottom of the shallow pan through the convex bank, and the remaining liquid is impregnated in the fibrous raw material sheet again by reversing the top surface and the bottom surface before use, so that the impregnating liquid can be effectively used.

In addition, as mentioned above, the convex embankment becomes a liquid reservoir, a liquid impermeable sheet is placed on the convex embankment, and a plurality of fibrous raw material sheets arranged in a horizontal direction are placed on the sheet, and the impregnating liquid is injected from above. When it is used, it can prevent the remaining liquid of the impregnating liquid that has not been completely absorbed by the fibrous raw material sheet from flowing from the opening area at the bottom of the shallow pan to the flat part of the pillow packaging body in a short time.

In addition, the liquid-impermeable sheet has the advantage of preventing condensation in the shallow dish.

The sealing surface of the newly formed pillow package is the top surface side, but the sealing surface will be located on the bottom surface side by inversion of the top surface and the bottom surface. When in use, open the opening and closing cover provided on the flat part of the pillow package that is positioned on the top side through the inversion of the top surface and the bottom surface, and remove the liquid impermeability between the above-mentioned convex bank and the wet sheet. After thinning, it can be removed by extracting the upper part of the laterally arranged wet sheet.

As the fibrous material sheet, a sheet made of raw materials such as woven fabric, nonwoven fabric, gauze, cotton, etc. is used, and liquid cosmetics or liquid medicines are impregnated in the above raw material.

In the wet sheet pillow packaging body of the present invention, the folded fibrous raw material sheets are arranged and stored in a shallow tray in a horizontal manner, and then the impregnating liquid is injected, and the sealing surface of the pillow packaging is used as the top surface side. The pillow package is formed by this method, and then the top surface and the bottom surface of the formed pillow package are reversed so that the impregnating liquid is fully distributed in the wet sheet, so that liquid cosmetics or liquid medicines can be impregnated efficiently.

As described above, when the impregnating liquid is preliminarily impregnated before being arranged and stored in the tray, the wet sheet can be more stably impregnated with the impregnating liquid.

In the wet sheet pillow packaging body of the present invention, fibrous raw material sheets such as woven fabrics, non-woven fabrics, gauze, and cotton as raw materials for forming wet sheets are folded and then arranged in a horizontal direction and stored in a shallow tray. The bottom surface is reversed, which can more efficiently impregnate liquid cosmetics, liquid medicines, etc., and it is excellent in portability and easy to open. So the economy is high.

In addition, on the basis that a plurality of fibrous raw material sheets can be packaged together at the same time, there is also the following advantage, that is, it is the same as the point of arranging the fibrous raw material sheets in the horizontal direction in the above-mentioned prior art container packaging. , but when it is necessary to impregnate a large amount of liquid, wet sheets in a laminated state, in which it is difficult to uniformly impregnate each fibrous raw material sheet, can be used as packaging objects.

Furthermore, the use of pillow packaging can greatly reduce the amount of plastic used compared with conventional plastic containers, so there is also an advantage of being able to provide environmentally friendly products.

For example, the product 100 of the horizontally arranged non-woven sheets impregnated with cosmetic water introduced as the prior art (Patent Document 1) in the present invention 100 is shown in Figures 14 and 15, and the packaging container body consists of a simple packaging made of paper. The body is formed and is composed of a storage portion 102 and a cover 101. A hard plastic container 110 is housed inside it. The plastic container 110 houses a tray 120 in a storage portion 111 of a tub-type (Tab) container. . After the nonwoven sheet is impregnated with lotion 123 as shown in FIG. 16 (left side), the middle cover 121 is covered, and then sealed with the cover 112 of a hard plastic container. When in use, take out the plastic container 110 stored inside the simple packaging box 100, open the cover 112, and then open the middle cover 121 of the platter 120 to take out the sheet 122 impregnated with lotion.

According to the above-mentioned packaging form of the box-shaped container in the above-mentioned prior art document, the sheets 122 impregnated with lotion are arranged and stored in the shallow tray 120 along the lateral direction, but the main body of the shallow tray 120 is stored in the container 110 formed of hard plastic. , so double wrapping is required.

The removal of the impregnated nonwoven fabric sheet in the above-mentioned prior art, as shown in FIG. The amount is small, and the lower part is more impregnated than required because the impregnating liquid is often accumulated. In this case, in the storage form using the above-mentioned box-shaped container, it is inevitable that the top and bottom of the non-woven fabric sheets arranged in the horizontal direction are uneven. Impregnated liquid.

On the other hand, in the wet sheet pillow package of the present invention, the problem of uneven impregnation of the upper and lower portions of the impregnated fibrous raw material sheet rarely occurs as in the above-mentioned prior art.

That is, as shown in Figure 1, prepare fibrous raw material sheets such as woven fabrics, non-woven fabrics, gauze, cotton, and a part of the bottom such as a shallow dish in which the roughly central part becomes an opening area, and the fiber raw material thin sheets are regularly accommodated in the horizontal direction in the shallow dish, Inject impregnation solution.

Even if the impregnating liquid is contained in the fibrous raw material sheets before they are arranged and stored in the tray, it does not have any influence on the subsequent steps.

In this state, pillow packaging is performed in such a way that the bottom of the shallow pan is directly connected to the bottom surface to form a pillow packaging body. While being transported and stored in this state, the top and bottom surfaces are reversed to impregnate the fibrous material sheet again with the impregnating liquid accumulated in the shallow pan. By impregnating the fibrous material sheet again, the impregnating liquid can be sufficiently distributed. The inversion of the top surface and the bottom surface can be carried out before use after transportation and storage, or before transportation and storage. The amount may become reduced, so after transportation and storage, the top and bottom surfaces are reversed as close as possible to the time of use, so that the impregnating liquid can spread more throughout the whole.

As shown in the perspective views of Figures 2 to 4 and the cross-sectional views of Figures 5 to 7, the shallow tray 10 of the wet sheet pillow package of the present invention is formed by a side wall 1, a bottom 2, and a convex embankment 3, and on the bottom 2 An opening area 4 is provided. A liquid-impermeable sheet 5 is placed on the convex bank 3 . In the tray 10, the folded fibrous material sheets 6 are arranged horizontally and accommodated. Into the fibrous material sheets arranged and accommodated in the platter 10, a liquid 7 such as a liquid cosmetic or a medicinal solution as an impregnating liquid is poured from above by an appropriate means. In addition, arrows in the figure indicate the top surface at the time of manufacture.

Before transportation and storage or after transportation and storage, the top surface and bottom surface of the above-mentioned package are reversed. However, if the time elapses after the inversion is long, the impregnation solution of the fiber raw material sheet on the take-out side may become insufficiently impregnated. , Therefore, it is better to reverse the top surface and the bottom surface as close as possible to the stage of use. 9 and 10 show cross-sectional views of the fibrous material sheets 51 and 52 , and FIG. 11 shows a plan view of the fibrous material sheet 53 .

The fibrous raw material sheet that becomes the wet sheet after impregnation can be a fiber raw material sheet of appropriate shape such as woven fabric, non-woven fabric, gauze, cotton, etc., and can also be a mask sheet as shown in Figure 12. Figure 13 shows its folded state.

In the present invention, fibrous raw material sheets such as woven fabrics, non-woven fabrics, gauze, and cotton are used, but in consideration of the impregnation property and good skin feel of liquid cosmetics, the materials are preferably fibrous raw materials with high hydrophilicity. Such fibrous raw materials are widely used in conventionally known wet sheet products such as wet sheets and mask sheets. In the present invention, the same fibrous raw materials can also be selected and used according to the purpose of use.

When a nonwoven fabric is used, it is preferably a nonwoven fabric with a basis weight of about 50 g/m ² , and the thickness of one sheet when impregnated with a liquid may be 200 to 800 μm. In addition, the thickness of the laminate obtained by laminating a plurality of fibrous raw material sheets may be 1,000 to 3,000 μm when impregnated with a liquid.

Furthermore, the shape of the fibrous raw material sheet to be impregnated is usually a rectangle, a square, an ellipse, etc., and may be cut into an appropriate size according to the purpose of use. In addition, if it is a mask sheet, it may be a shape that covers the entire face, or may be a shape that fits the shape of the forehead, cheeks, and the like.

The fibrous raw material sheets are usually folded into two or three equal parts, folded in a Z shape or a U shape, preferably arranged and stored in such a way that the folding line contacts the bottom of the shallow dish. A commercially available folder can be used for folding the sheet.

In the present invention, liquids such as liquid cosmetics and liquid medicines impregnated in the fibrous raw material sheet may be liquids widely used in wet sheet products such as conventionally known wet sheets or mask sheets. For example, from the viewpoint of moisture retention, skin feeling, etc., it is preferable to incorporate a water-soluble polymer, and in addition to this, whitening ingredients, blood circulation-promoting ingredients, and the like can also be optionally added.

In addition, the viscosity of the liquid to be impregnated is preferably 1 to 5,000 mPa·s, and if the viscosity is too high, it is impossible to impregnate a large amount of the fibrous raw material sheet.

Furthermore, the impregnation ratio is preferably 7 to 9 times (impregnation rate 700 to 900%).

The packaging technique used in the present invention is horizontal pillow packaging, and the wet sheet package of the present invention can be efficiently produced by using a commercially available reverse pillow packaging machine. In addition, as the plastic film used for pillow packaging, a laminated film formed by laminating synthetic resins may be used as appropriate depending on the situation.
