Description

Wet sheet pillow package

The present invention relates to a wet sheet pillow package in which a fiber material sheet such as a nonwoven fabric is impregnated with a liquid such as a liquid cosmetic or a chemical solution.
More specifically, in the present invention, a wet sheet such as a wet tissue or a face mask sheet is arranged and stored horizontally in a tray so that a predetermined amount of impregnation liquid is uniformly impregnated in the vertical direction, and the top surface and the ground are reversed when used. In particular, the present invention relates to a wet sheet pillow package that enables a sheet to be taken out from a tray bottom opening area that is in contact with an outlet of the pillow package.

Conventionally, lotion is used by putting the lotion taken out of the container into a woven fabric, non-woven fabric, gauze, cotton or other fiber material sheet so that the face is tapped (putting). In addition, it takes time and effort to impregnate a lotion into the sheet at the time of use, and the amount of the lotion applied to the skin is excessive or insufficient, the feeling of use is bad, the makeup effect is not obtained, etc. There was a problem.
Therefore, wet tissues in which lotion is pre-impregnated into a fiber material sheet such as woven fabric, non-woven fabric, gauze, and cotton are known, and many types of products according to user needs are now offered. It has become.
The impregnating liquid is not limited to lotion, and may be frequently used for washing and disinfecting hands and skin by impregnating a chemical liquid used for normal cleaning and disinfection.
Recently, wet sheets such as wet tissues and face mask sheets impregnated with liquid cosmetics have been widely used and used for cleansing and skin care.
Wet tissue used for washing and disinfecting hands and skin is a unit of several tens of sheets that are folded one by one and stacked vertically or vertically, or a continuous sheet with one cut line. On the other hand, the stationary type products stored in a cylindrical container or a box-type container with an outlet are the mainstream, but several to ten sheets of sheets that are individually folded one by one are stacked vertically or vertically. Portable products are also provided that are housed in plastic film packages such as pillow packages with outlets in units of several sheets.

Wet sheets used for cleansing, skin care, etc. may be costly by impregnating expensive liquid cosmetics, or in some cases increasing the amount of skin water impregnated into the sheet base. In order to increase value, products that are folded individually or individually in multiple sheets to increase value are the mainstream, but some of them are folded vertically or vertically in multiple units with emphasis on economy. A product arranged in a direction and stored in a box-shaped container is also known.
In this way, in response to various needs, wet sheet packages in which liquid material sheets such as woven fabrics, non-woven fabrics, gauze and cotton are impregnated with liquids such as liquid cosmetics and chemicals are widely used as general-purpose daily goods and cosmetics. ing.

For the above-described wet sheet packaging, so-called soft packaging, in which products are packaged with a plastic film, is widely used, and it is widely used because it has many excellent advantages including economic efficiency.
As one form of soft packaging using this plastic film, pillow packaging that wraps a product while forming a packaging film from a bowl shape into a tubular shape is typical.

Pillow packaging is one of the most widely used packaging methods at present, and products to be packaged are packaged in pillow (pillow) shaped bags, and the products to be packaged are horizontal (horizontal) with respect to the packaging machine. When supplied from the direction and packaged in a tubular shape, it is called a horizontal pillow, and when packaged in the vertical direction, it is called a vertical pillow.
This pillow wrapping basically consists of a supply part for supplying plastic film for wrapping the article to be packaged, a former part for making the plastic film fed from the supply part into a cylinder, and the article to be packaged inside the cylindrical plastic film. Loading section (conveyor) to be loaded, center seal section for heat-sealing the edges of cylindrical plastic films containing the items to be packaged, drawer section for determining the cut dimensions of the center-sealed plastic film package, cut dimensions A sealing means for sealing and cutting a predetermined cylindrical plastic film packaging body, the center seal is located at the center of the plastic film packaging body, and the packaging means is shaped so that the folded portion of the plastic film forms the side surface of the packaging body (Non-Patent Document 1).
Such pillow packaging has the convenience of the manufacturer's economy that the production process can be packaged at high speed, the convenience that the resulting product is portable and easy to open, and this packaging means also in the cosmetics field. Many products, such as dry tissue and wet sheets, are produced.

Recently, many wet sheets impregnated with liquid cosmetics, such as wet tissues and face mask sheets, have been commercialized and have been used to moisturize and moisturize the skin. For the sheet, there is a demand for a wet product impregnated with a large amount of liquid cosmetic material in order to obtain a higher effect.
For example, when liquid cosmetics are impregnated with individually packaged wet sheet packaging, there is no problem with uneven quality of the uniform amount of impregnation if the economy of using an excessive amount of impregnating liquid is ignored, but the economy When using the minimum amount of impregnating solution in consideration of the above, a large number of wet sheets are stacked and stored in one direction (in many cases, vertically or vertically) in a conventional manner. When the amount of liquid cosmetic impregnated in each wet sheet is close to the lower part, the amount of impregnation is large, and the part close to the upper part has a problem that the amount of impregnation is insufficient. It was difficult to uniformly and efficiently impregnate the impregnating solution uniformly.
Conventionally, a wet sheet package body in which a large number of folded wet sheets are stored in a horizontal direction and impregnated is publicly known (Patent Document 1). It was difficult to homogenize, and it could not be said to be a wet sheet product with good economic efficiency and good impregnation efficiency like the pillow packaging of the present invention.

JP 2008-150317 A

As described above, when trying to provide a wet sheet impregnated with a large amount of liquid such as liquid cosmetics or chemicals ignoring economic efficiency, it is necessary to bring a fiber material sheet such as a nonwoven fabric into contact with a sufficient amount of liquid. As a result, it was necessary to fill the container with the liquid, and this could not be realized by pillow packaging.
On the other hand, packaging in the form of a container that can secure a sufficient amount of liquid lacks convenience, tends to result in excessive packaging, and cannot satisfy economic efficiency.
The known wet sheet packaging body (Patent Document 1) described above, which is a packaging in a container form, has a large number of side-by-side arrangements stored in a synthetic resin box-shaped container in a state in which a fiber material sheet such as a nonwoven fabric is folded. Later, it is a wet sheet product in which a cosmetic liquid is poured into the container and impregnated into the sheet, but since a synthetic resin box type container is used for packaging, it is a batch type and troublesome packaging form, such as pillow packaging Thus, a wet sheet package was not easily obtained economically.
Accordingly, an object of the present invention is to provide a packaging body in which the amount of liquid cosmetic impregnated into a wet sheet is uniform in the vertical and horizontal directions, and the wet sheet can be easily taken out, even if the packaging form accommodates a large number.

In order to solve the above-described problems, the present invention basically has the following configuration.
(1) A pillow package for packaging a tray containing a wet sheet, wherein an opening area corresponding to a wet sheet outlet is formed at the approximate center of the bottom of the tray. A wet sheet take-out port is provided in the flat part on the opposite side of the surface, and a plurality of folded wet sheets are arranged and stored side by side in the tray. A featured wet sheet pillow package.
(2) The wet sheet pillow package according to (1), wherein the folds of the wet sheet are arranged and stored so as to contact the bottom of the tray.
(3) The wet sheet can be individually taken out through the tray opening area and the outlet of the flat portion by opening and closing the opening / closing lid provided on the flat portion on the opposite surface of the palm surface (1) or (2 ) The wet sheet pillow package according to the above.
(4) The wet sheet pillow according to any one of (1) to (3), wherein the opening area at the bottom of the tray itself is formed by a protruding ridge for storing a surplus impregnating liquid. Packaging body.
(5) The liquid impervious sheet is interposed in the gap between the plurality of wet sheets stored in the tray so as to be sideways and the ridges, (1) to ( The wet sheet pillow package according to any one of 4).
(6) The wet sheet pillow package according to any one of (1) to (5), wherein the wet sheet is formed from a fiber material sheet.
(7) The wet sheet pillow package according to any one of (1) to (6), wherein the wet sheet is impregnated with a liquid cosmetic or a chemical solution.

The wet sheet pillow package of the present invention is characterized in that the top surface and the ground of the wet sheet pillow package are reversed when the wet sheet is taken out.
In other words, the wet sheet pillow package of the present invention is a wet sheet pillow package in which a tray in which individual folded fiber material sheets (referred to as wet sheets after impregnation) are individually arranged and stored is subjected to reverse pillow packaging. However, the wet sheet take-out port provided on the flat surface opposite the mating surface of the pillow package body communicates with the wet sheet take-out opening area provided at the approximate center of the bottom of the tray. At the time of taking out the sheet, the wet sheet can be taken out from the outlet on the top surface side through the tray opening area which is also located on the top surface side.
In the present invention, the top surface is the side facing the top or the top, and the ground is the side facing the ground or the bottom.

In general, there are two types of pillow wrapping: normal pillow wrapping and reverse pillow wrapping, but when pillow wrapping trays that contain folded fiber material sheets is used, if regular pillow wrapping is used, an open area is provided at the bottom of the tray. It is not necessary to provide, but the upper portion of the tray that is tapered is located on the flat surface where the wet sheet take-out port is provided on the opposite side of the mating surface of the pillow package. There is a problem that the tray is deformed or broken by opening / closing the opening / closing lid or stacking of products. On the other hand, when reverse pillow packaging is used, as described above, the strong tray bottom is located on the flat surface where the wet sheet outlet is provided. There is an advantage that the deformation or breakage of the tray does not occur.

The fiber material sheets of the present invention are individually folded and accommodated in a plurality of trays so as to be turned sideways, and the impregnating liquid injected in this state is impregnated from above the fiber material sheets. The folding and arrangement storage of the fiber material sheet may be left unimpregnated with the impregnating liquid, or may be impregnated with the impregnating liquid.
In addition, by arranging and storing the folds of the fiber material sheet so as to be in contact with the bottom of the tray, there is an advantage that the wet sheet stored in the pillow package is easily taken out and the stability on the tray is improved.
When the pillow package is formed, the palm surface is located on the top side, but the top and ground are reversed during use, so the pillow surface is located on the ground side. The open / close lid provided on the flat surface of the tray is opened, and the wet sheet can be taken out individually through the opening area at the center of the tray bottom (located on the top side when the top and ground are reversed).

The opening area in the approximate center of the bottom of the tray is demarcated by a ridge, and this ridge serves as a reservoir for excess impregnation liquid. The surplus liquid of the injected impregnating liquid is accumulated at the bottom of the tray by the ridge, and the surplus liquid is impregnated again into the fiber material sheet by reversing the top surface and the ground before use, so that the impregnating liquid is effectively used. it can.
Also, as described above, since the ridge is a liquid reservoir, a liquid-impermeable sheet is placed on the ridge, and a plurality of fiber material sheets are arranged and housed side by side on the sheet. When the impregnating liquid is poured from above, excess liquid of the impregnating liquid that could not be absorbed into the fiber material sheet in a short time is prevented from flowing out from the opening area of the tray bottom to the flat part of the pillow package. Can do.
In addition, the liquid-impermeable sheet has an advantage that condensation in the tray can be prevented.

合 The palm surface immediately after the formation of the pillow package is the top surface side, but the palm surface is positioned on the ground side due to the reverse of the top surface and the ground surface. In use, open the open / close lid provided on the flat surface of the pillow package that has been positioned on the top surface side by reversing the top surface and the ground, and remove the liquid that is located between the ridge and the wet sheet. After removing the permeable sheet, the upper part of the wet sheet arranged in the horizontal direction can be picked and removed.

As the fiber material sheet, a sheet formed of a material such as woven fabric, non-woven fabric, gauze, or cotton is used, and the material is impregnated with a liquid such as a liquid cosmetic or a chemical solution.
In the wet sheet pillow package of the present invention, a plurality of folded fiber material sheets are arranged and stored in a tray so that the sheet faces sideways, and then an impregnation liquid is injected, and the palm surface of the pillow package is the top side. The pillow packaging body is formed so that the top surface and the ground of the pillow packaging body are reversed, and the impregnating liquid is sufficiently distributed in the wet sheet, thereby efficiently liquid cosmetics or chemicals Etc. can be impregnated.
As described above, when the impregnation liquid is impregnated in advance before storing the arrangement in the tray, the wet sheet can be impregnated with the impregnation liquid more stably.

The wet sheet pillow package of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a flow sheet for manufacturing a wet sheet pillow package of the present invention, FIG. 2 is a perspective view of a tray for storing the wet sheet of the present invention, and FIG. 3 is a liquid-impermeable sheet on a ridge on the bottom of the tray. 4 is a perspective view of a state in which a folded fiber material sheet is stored in a tray, FIG. 5 is a cross-sectional view in the direction AA of FIG. 2, and FIG. 6 is a perspective view of FIG. FIG. 7 is a cross-sectional view taken along the line CC of FIG. 4, FIG. 8 is a cross-sectional view when the wet sheet pillow package of the present invention is used, and FIG. 9 is stored in a tray. FIG. 10 is a modification of the fiber material sheet, FIG. 11 is a plan view of the fiber material sheet, FIG. 12 is a plan view of the face mask sheet as the fiber material sheet, and FIG. 13 is the face mask sheet. 14 shows a state of folding, and FIG. 14 shows a lotion impregnation introduced as a prior art. FIG. 15 is a perspective view of a container-type package housed inside the product, and FIG. 16 is a state of injecting lotion into the product. The conceptual diagram of the left side) and the decorative sheet removal situation (right side) is shown.

For example, a product 100 containing a lotion-impregnated laterally arranged nonwoven fabric sheet introduced as prior art (Patent Document 1) in the present invention is shown in FIGS. 14 and 15, and the packaging container itself is made of paper. It consists of a simple packaging body and is composed of a storage portion 102 and a lid 101. Inside, a hard plastic container 110 is accommodated, and the plastic container 110 accommodates a tray 120 in a storage part 111 of a tab-type container, and a lotion-impregnated sheet 122 is placed sideways on the tray 120. The array is stored. As shown in FIG. 16 (left side), the non-woven fabric sheet is impregnated with lotion 123, and then covered with an inner lid 121, and further sealed with a lid 112 of a hard plastic container. In use, the plastic container 110 stored inside the simple packaging box 100 is taken out, the lid 112 is opened, the inner lid 121 of the tray 120 is further opened, and the lotion-impregnated sheet 122 is taken out.
In the packaging form using the box-shaped container in the prior art, the lotion-impregnated sheets 122 are arranged and stored in the tray 120 in the horizontal direction, but the tray 120 itself is stored in the container 110 made of hard plastic. Double packaging is required.
The removal of the impregnated nonwoven sheet in the above prior art is performed by picking and removing the upper part of the impregnated nonwoven sheet as shown in FIG. 16 (right side). The amount of impregnation increases more than necessary because the impregnation liquid always stays in the lower portion. Thus, in this case, in the storage form using the above-mentioned box-shaped container, unevenness is not avoided above and below the laterally arranged nonwoven fabric sheet. An excessive amount of impregnation liquid must be injected.

On the other hand, in the wet sheet pillow package of the present invention, as in the above prior art, non-uniform impregnation hardly occurs in the upper part and the lower part of the impregnated fiber material sheet.
That is, as shown in FIG. 1, a fiber material sheet such as woven fabric, non-woven fabric, gauze, and cotton and a tray having a part of the bottom, for example, a substantially central portion as an open area, are prepared. Are regularly stored in the lateral direction, and the impregnating liquid is injected.
Even if the fiber material sheet before being arranged and stored in the tray contains an impregnating liquid, there is no problem in subsequent processes.

In this state, the pillow is wrapped with the tray bottom in contact with the ground to form a pillow package. In this state, the sheet is transferred and stored, and the top surface and the ground are reversed so that the impregnating liquid staying in the tray is impregnated again into the fiber material sheet. The impregnating liquid is sufficiently distributed to the fiber material sheet by re-impregnation. The reversal of the top surface / ground may be before use after transfer / storage, or before transfer / storage. Since there is a possibility of a decrease, the impregnating liquid is more completely distributed by reversing the top surface and the ground before the time as close to use as possible after transportation and storage.

As shown in the perspective views of FIGS. 2 to 4 and the cross-sectional views of FIGS. 5 to 7, the tray 10 of the wet sheet pillow package of the present invention comprises a side wall 1, a bottom 2, and a protruding ridge 3. Is provided with an open area 4. A liquid-impermeable sheet 5 is placed on the ridge 3. In the tray 10, the folded fiber material sheets 6 are arranged side by side and stored. A liquid material 7 such as a liquid cosmetic or a chemical liquid is injected as an impregnating liquid into the fiber material sheet after being stored in the tray 10 by an appropriate means. In addition, the arrow in a figure shows the top | upper surface at the time of manufacture.

The top / ground of the package is reversed before transfer / storage or after transfer / storage, but if the time elapsed after the reverse is long, the impregnation liquid of the fiber material sheet on the take-out side may become insufficiently impregnated. If it is close to use, it is better to reverse the top and ground. 9 and 10 are cross-sectional views of the

fiber material sheets

51 and 52, and FIG. 11 is a plan view of the fiber material sheet 53.
The fiber material sheet to be a wet sheet after impregnation may be a fiber material sheet having an appropriate shape such as woven fabric, non-woven fabric, gauze, or cotton, but may also be a face mask sheet as shown in FIG. FIG. 12 shows the folded state.

In the present invention, a fiber material sheet such as woven fabric, non-woven fabric, gauze, and cotton is used. The material is preferably a highly hydrophilic fiber material in view of the impregnation property of liquid cosmetics and good touch. Such fiber materials are widely used in wet sheet products such as wet sheets and face mask sheets that have been conventionally known. In the present invention, similar fiber materials are selected and used according to the purpose of use. It ’s fine.

When using a non-woven fabric, the basis weight is preferably around 50 g / m ^2, and the thickness of one sheet at the time of liquid impregnation may be 200 to 800 μm. Further, the thickness of the laminate in which a plurality of fiber material sheets are laminated may be 1,000 to 3,000 μm at the time of liquid impregnation.
Furthermore, the shape of the fiber material sheet used for impregnation is generally rectangular, square, elliptical or the like, and may be cut into an appropriate size according to the purpose of use. Further, in the case of a face mask sheet, it may have a shape that covers the entire face, or a shape that matches the shape of the forehead, cheeks, or the like.
The fiber material sheet is generally folded in two or in three, and may be folded and folded in a Z-shape or U-shape, and preferably stored in an array so that the fold line is in contact with the bottom of the tray. A commercially available folding machine can be used for folding the sheet.

Liquids such as liquid cosmetics and chemicals impregnated in the fiber material sheet in the present invention may be those widely used in wet sheet products such as wet sheets and face mask sheets that are conventionally known. For example, it is preferable to blend a water-soluble polymer from the viewpoints of moisture retention and touch, and in addition, a whitening component, a blood circulation promoting component, etc. may be selected and blended.
The viscosity of the liquid to be impregnated is preferably 1 to 5,000 mPa · s. If the viscosity becomes too high, the fiber material sheet cannot be highly impregnated.
Further, the impregnation ratio is preferably 7 to 9 times (impregnation rate 700 to 900%).

The packaging technology 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, what is necessary is just to use the laminate film which laminated | stacked the synthetic resin suitably according to the situation as the plastic film used for pillow packaging.

In the wet sheet pillow package of the present invention, as a material for forming the wet sheet, folded fabric material sheets such as woven fabric, non-woven fabric, gauze, and cotton are arranged horizontally and stored in the tray. It can be efficiently impregnated with liquid cosmetics and chemicals by reversing the top and ground, and it is easy to open and easy to open. Since a general-purpose packaging form is adopted, it is highly economical.
In addition, a large number of fiber material sheets can be integrally packaged at the same time, and the container packaging in the prior art is impregnated with a large amount of liquid even though it is common in that the fiber material sheets are arranged in the lateral direction. When necessary, there is an advantage that a wet sheet in a laminated state, which is difficult to uniformly impregnate each fiber material sheet, can be applied as a packaging target.
In addition, the pillow packaging can greatly reduce the amount of plastic used compared to conventional plastic containers, and therefore has the advantage of providing environmentally friendly products.
