Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sheet in which a plurality of sheets, such as a wet tissue, are stored in a container or a package so that the sheets can be sequentially taken out.
More particularly, the present invention relates to a continuously stored sheet in which a mark is attached to a sheet so that a user can know a decrease in the number of remaining sheets in a container or a package.
[0002]
[Prior art]
Wet tissues for wiping the butt, for makeup, etc. are stored in a form that can be taken out one by one in a hard container or a package formed of a laminated film.
For example, a box-shaped rigid container 10 shown in FIG. 9 includes a box body 11, a lid 12, an outlet 14 formed in the lid 12, and a small lid piece 13 that opens and closes the outlet 14. The rigid container 10 has high hermeticity so that a sheet impregnated with a chemical solution such as a wet tissue or a lotion can be stored while being kept moist. The sheets 1 are stored in the rigid container 10 in a state of being folded and stacked one by one alternately. When the sheet 1 is taken out from the take-out port 14, the sheet 1 is dragged by the taken-out sheet 1, and the next sheet remains in a state of being partially projected from the take-out port 14. By pulling the protruding sheet end with a finger, the next sheet can be taken out.
[0003]
The cylindrical rigid container 20 shown in FIG. 10 also has a container body 21, a lid 22, an outlet 24 formed in the lid 22, and a small lid piece 23. In the hard container 20, a continuous band-like sheet is stored in a state of being wound in a cylindrical shape, and a perforation is formed so that a sheet of a predetermined length can be separated. When the sheet wound in a cylindrical shape is pulled out from the outlet 24 and pulled, the sheet is separated from the perforated portion with the perforated portion coming out of the outlet 24, and only one sheet is taken out. . Then, the remaining sheet partially protrudes from the outlet 24 and remains. The next sheet can be taken out by grasping and pulling this protruding portion.
[0004]
[Problems to be solved by the invention]
However, in the case of the hard container 10 or 20 as shown in FIG. 9 or FIG. 10, since the sheet 1 such as a wet tissue stored inside cannot be seen from the outside, the number of remaining sheets in the container is not known. Therefore, it is inconvenient in that when the number of remaining sheets becomes small during use or when the sheets are exhausted, this cannot be predicted.
For example, in a so-called box tissue in which dry tissue papers are stored one by one in a paper box in a form capable of being taken out, a certain number of tissue papers in the lowermost layer are colored, and the number of remaining tissue papers is decreasing. This can be notified to the user.
[0005]
However, when the above-mentioned coloring is applied to a material such as a wet tissue which is impregnated with a liquid such as a chemical solution or a lotion, the coloring additive mixes with the liquid on the sheet and bleeds. In addition, if a coloring additive is added to a wet tissue that touches the skin, such as for wiping the ass or for makeup, it may adversely affect the skin.
Further, Japanese Utility Model Laid-Open No. 4-56638 discloses a device for forming a window in a container containing a wet tissue so that the inside of the container can be viewed. However, forming a transparent window in the container complicates the structure of the container and increases the cost. In the case where the sheet as shown in FIG. 10 is stored in a cylindrical shape, the sheet in the container body 21 is still cylindrical even if the number of remaining sheets is reduced. For this reason, even if a transparent window is formed in the container main body 21, the reduced state of the sheet cannot be accurately grasped visually.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet that can be continuously stored, in which a decrease in the number of remaining wet tissues or the like in a container or a package can be known, and the sheet does not need to be colored.
[0007]
[Means for Solving the Problems]
The continuously stored sheets of the present invention are the sheets stored in a form that can be sequentially taken out from the container or the package, and the container after a predetermined number of sheets are taken out from the container or the package. Alternatively, one or more of the sheets remaining in the package are marked with a mark in which the surface of the sheet is deformed in a submerged state.
[0008]
Further, the sheet includes a thermoplastic resin fiber, and the mark is formed by melting the thermoplastic resin fiber.
[0009]
The sheet in the present invention is, for example, a nonwoven fabric such as spunlace. Pressurizing and heating by heat roll, or the thermoplastic resin fibers are melted by such self-induction heating to provide a pressurized ultrasonic horn and the anvil to form a embossed marks on the sheet. In the mark formed by melting the thermoplastic resin fiber, the melted portion becomes a film and the whiteness and gloss are different from those of the other portions of the sheet, so that the mark can be visually confirmed. In addition, since the melted portion becomes a surface sinking shape and the melted portion becomes slightly hard, it is easy to check the presence or absence of a mark by touching with a hand. Further, the appearance of the sheet is improved by forming the pattern in the surface immersion shape.
[0010]
The thermoplastic resin fibers are polyethylene (PE) fibers, polypropylene (PP) fibers, or composite fibers of PE and PP.
[0011]
Further, the continuously stored sheets of the present invention are the sheets stored in a form that can be sequentially taken out of the container or the package, and after a predetermined number of sheets are taken out from the container or the package, One or more of the sheets remaining in the container or the package are provided with a mark formed by an opening.
[0012]
When a mark is formed an opening in the sheet, the thermoplastic resin fibers around the opening portion is welded. As the thermoplastic fiber around the opening is melted and cured by heat and welded, the periphery of the opening becomes slightly harder, making it easier to touch and confirm the presence or absence of a mark. Since the fibers are welded, the opening becomes reliable, and the fibers can be prevented from fraying at the peripheral edge of the opening.
[0013]
As means for forming the opening, it is conceivable to pierce the sheet with a heated needle. When the sheet is pierced with the needle-like material, a thermoplastic fiber at the periphery of the opening can be welded at the same time as forming a hole in the sheet. Further, the aperture containing the thermoplastic fiber may be strongly pressed by a horn and an anvil that generates ultrasonic waves to melt the thermoplastic resin to form the opening.
[0014]
The mark of the submerged or open portion may be formed evenly on the entire surface of the sheet, but as shown in FIGS. 9 and 10, it is formed at the leading end on the take-out side and in the central region of the sheet. Preferably, it is not formed. By setting the center of the sheet as a region where no mark is formed, the soft feeling of the central region, which is a portion to be applied to the skin, does not decrease. Furthermore, it is possible to prevent the strength of the sheet in the central region, which is the portion to be wiped, from being reduced.
[0015]
Furthermore, in the present invention, since the user can know that the number of remaining sheets in the container is small without coloring the sheets, a wet sheet impregnated with a liquid such as a chemical solution or lotion (for example, a wet sheet) It is effective to apply the method to a sheet which is not preferable if it is colored as in a tissue. However, the present invention is not limited to a wet sheet, and can be applied to a dry sheet for cleaning a kitchen.
[0016]
In the present invention, if the mark on the sheet indicates the actual number of sheets left in the container or the package, the remaining amount of the sheet can be accurately known.
[0017]
The present invention is not limited to a sheet accommodated in an opaque hard container as shown in FIGS. 9 and 10, but may be applied to a sheet accommodated in a soft container, a paper container, or a package formed of a laminated film. Can also be implemented.
[0018]
Further, the marks attached to the sheets are sequentially changed one by one or a plurality of sheets according to the remaining number of sheets in the container or the package, whereby the decrease in the number of remaining sheets in the container or the package is sequentially known. It is also possible to do it.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings.
The sheet of the present invention is folded and stacked in a box-shaped rigid container 10 as shown in FIG. When the sheets 1 are taken out one by one from the take-out port 14, the end of the next sheet partially protrudes from the take-out port 14. Alternatively, a belt-shaped sheet is stored in a cylindrical hard container 20 as shown in FIG. 10 in a state of being wound in a cylindrical shape, and cut out one by one at the perforation when it comes out of the outlet 24, and is taken out. The next sheet remains in the mouth 24.
[0020]
The sheet 1 is a nonwoven fabric such as spunlace, and includes one or more types of thermoplastic resin fibers. The thermoplastic resin fibers are polyethylene (PE) fibers, polypropylene (PP) fibers, or composite fibers of PE and PP. This thermoplastic resin fiber and an absorbent fiber such as rayon fiber are mixed and entangled to form a fiber web W.
The sheet 1 is used as a wet sheet (wet tissue) by impregnating a liquid such as cleansing water or alcohol or a liquid such as lotion.
[0021]
The sheets taken out one by one from the container 10 or 20 are basically not marked, but the last one or several sheets remaining in the container 10 or 20, or the predetermined number of the last sheets are left. One or a plurality of sheets to be taken out are marked 1b as shown in FIG.
In the sheet shown in FIG. 1, the mark 1b is attached only to a region having a predetermined width L on the leading end side 1a protruding from the outlet 14 of the container 10 or the outlet 24 of the container 20 by being pulled by the preceding sheet, The other parts, especially the central area of the sheet 1, are not marked. The width L is preferably, for example, about 10 mm to 20 mm.
[0022]
FIG. 2 is an enlarged cross-sectional view of a portion of the sheet 1 shown in FIG.
As shown in FIG. 2, the fiber web W containing thermoplastic resin fibers is heated by being partially pressed by the convex portion of the heat roller, or is partially pressed by the horn and the anvil to apply ultrasonic waves. As a result, the thermoplastic resin fibers in the fiber web W are melted by self-induced heat, and the embossed mark 1b in which the sheet surface is submerged is formed.
[0023]
The mark 1b is partially pressurized (narrow pressure), heat-fused, and flattened to form a film. Since the portion other than the mark 1b is bulky, the thickness of the sheet changes between the mark 1b and other portions. The portion of the mark 1b melted by pressurization is in the form of a film and is transparent or translucent, and the other portion is white because of the bulk of the fiber. As described above, since there is a difference between the thickness of the sheet of the mark 1b and the sheet of the other part, and a difference in whiteness, the mark 1b is easy to see with the eyes, and also easy to feel when touched with a finger.
Therefore, when sheets are taken out one by one from the take-out port 14 of the container 10 shown in FIG. 9 or the take-out port 24 of the container 20 shown in FIG. 10, the sheet 1 with the mark 1b shown in FIG. Can be immediately confirmed that the leading end 1a of the container has protruded from the outlet, and it can be known that the remaining number of sheets in the container is small.
[0024]
In FIG. 1, the mark 1b is formed only at the end of the sheet protruding from the outlet 14 or 24, and the mark 1b is not formed in the central area of the sheet. The portion of the mark 1b is relatively hard because the thermoplastic resin fiber is melted and is substantially in the form of a film, and the portion of the mark 1b has a slightly reduced sheet strength. Therefore, if the mark 1b is not formed in the area of the center of the sheet which is used for touching or wiping the skin, the soft feeling when touching the skin is not impaired. There is no such thing as tearing.
[0025]
The mark 1b can be freely determined by, for example, the shape of the convex portion of the heat roll that presses and heats the nonwoven fabric web W. For example, it may have a stripe shape as shown in FIG. 3A in the sheet width direction, a stripe shape as shown in FIG. 3B, or a lattice shape as shown in FIG. Alternatively, as shown in FIG. 3 (D), the mark 1b can be formed with characters or designs, or with characters or designs such as a product name or a manufacturer name. As described above, the shape and design of the mark 1b can be freely determined, so that the appearance of the sheet is excellent.
[0026]
Further, as shown in FIG. 4A, the mark 1b may be formed at both the leading end and the trailing end of the sheet 1 in the drawing direction. Further, as shown in FIG. 4B, a mark 1b may be formed on the entire surface of the sheet 1. However, when the mark 1b is formed on the entire surface of the sheet, the pitch of the mark 1b is increased so as to impair the soft feeling of the nonwoven fabric or to extremely reduce the sheet strength. It is preferable to make the area of the fused portion of the mark 1b smaller.
[0027]
The sheet 1 shown in FIG. 5 is a spun-lace nonwoven fabric or the like containing thermoplastic fibers as described above, and the mark 1 d is formed by opening the sheet 1. In the sheet 1 shown in FIG. 5, similarly to the sheet of FIG. 1, the mark 1d is formed only in a region of a predetermined width L on the leading end side 1c that is drawn and protruded by the preceding sheet. The other parts, especially the central area of the sheet 1, are not marked. The width L is preferably, for example, about 10 mm to 20 mm.
[0028]
The diameter of the mark 1d formed by the opening is preferably 0.5 mm or more and 1.5 mm or less. If the diameter of the opening is smaller than 0.5 mm, it is difficult to confirm the presence of the hole with the naked eye. On the other hand, if the diameter is larger than 1.5 mm, the strength of the sheet deteriorates. Further, the distance from one hole to an adjacent hole is preferably 1 mm or more. If the distance is smaller than 1 mm, the strength of the sheet may be deteriorated, or the holes may be torn and adjacent holes may be connected.
As shown in FIG. 5 (A), the arrangement of the openings serving as the marks 1d may be such that the rows form a straight line and the rows are arranged in parallel. Alternatively, as shown in FIG. 5B, characters, symbols or patterns may be formed by continuous dotted lines in the opening. Further, the dotted lines may represent the vertical stripes shown in FIG. 3B or the lattices shown in FIG. 3C. In this manner, the shape of the mark 1d formed by the opening can be freely selected, and a pattern can be drawn to make the design excellent.
[0029]
FIG. 6 is an enlarged cross-sectional view showing an example of a step of forming the opening shown in FIG.
In FIG. 6, a heated opening needle N is used to form an opening serving as a mark 1d. When this opening needle N is heated to a temperature equal to or higher than the melting point of the thermoplastic resin fibers blended in the sheet 1 and pierces the sheet 1, the thermoplastic resin fibers in the fiber web W are melted and the opening portion becomes At the same time, a welded portion 1e is formed at the periphery of the opening. This welded portion 1e is transparent or translucent. However, the other part is white because it is a fiber layer. Therefore, the mark 1d is easily distinguished from other parts of the sheet 1 because the hole is formed and the peripheral edge is transparent or translucent. Further, when the end of the sheet 1 is pinched with a finger, the tactile sensation of the mark 1d is different from the tactile sensation of the sheet surface, so that the number of remaining sheets decreases when the end of the sheet 1 is gripped. You can recognize that.
[0030]
Further, when the welded portion 1e is formed at the peripheral edge of the opening, the fibers of the sheet 1 are not frayed at the peripheral edge of the opening, and the aperture is not blocked by the fiber.
The mark 1d shown in FIG. 5 (A) or (B) can be formed by sequentially piercing the hole with the hole needle N. For example, the hole needle N in which a large number of lines are aligned, or a character It is preferable to form a large number of apertures in the sheet 1 at the same time by using a plurality of aperture needles N arranged in a shape such as a circle or a figure.
[0031]
In this manner, the mark formed by the thermoplastic resin fiber being hot-melted and opened is such that the area of the welded portion 1e of the fiber is limited only to the periphery of the opening, so that the soft feeling is less reduced and the area where the sheet deteriorates is reduced. Less is. Furthermore, if the mark 1d is not formed in a portion in the center area of the sheet that is used for touching or wiping the skin, the soft feeling when touching the skin is not impaired. In addition, since the sheet strength of the mark 1d is slightly lowered, if the mark 1d is formed avoiding the central area of the sheet, the sheet will not be torn when the dirt is wiped off.
[0032]
7 (A), 7 (B) and 8 show that the number of remaining sheets can be reduced in order by using a landmark 1b or a landmark 1d formed by an opening.
In FIG. 7A, the remaining number of sheets in the container or the package is represented by a number that changes sequentially, such as 5, 4, 3, 2, 1, and the like. This number may be formed by pressing the fiber web W of the sheet 1 so as to be submerged as in the embodiment shown in FIG. 1 and the following embodiments, or formed by a dotted line in which the openings are arranged as shown in FIG. May be.
[0033]
In FIG. 7B, the number of dots displayed by the landmarks 1b or the holes 1d is changed according to the change in the number of remaining sheets. Even with such a mark, the decrease in the remaining number of sheets can be sequentially known.
In addition, when a number or a dot representing the remaining number of sheets is attached, a mark such as the same number is attached to a predetermined number of sheets such as four or five sheets as shown in FIG. It may change for each sheet.
In the case where the remaining number of sheets is sequentially expressed by the number or the number of dots, several sheets without the mark should be left next to the sheet with the mark 1b or 1d representing the last sheet. You may.
[0034]
【The invention's effect】
As described in detail above, the continuously stored sheets of the present invention reduce the number of remaining sheets by looking at the marks formed on the sheets when the sheets are taken out one by one from the container or the package. You can know what you are doing. Further, since the mark is formed in a submerged state or formed by opening a hole, it can be confirmed by touching with a hand. In particular, when a mark is formed by melting the thermoplastic resin fiber, the boundary between the mark and another portion is clear, and the mark becomes conspicuous. When the mark is an opening, the opening is ensured by welding the fibers.
[0035]
Further, since it is not necessary to color the sheet with a coloring additive, there is no possibility that a wet sheet impregnated with a chemical or a lotion will adversely affect the skin.
[0036]
In addition, a distinguishable mark may be formed only at a portion protruding from the opening of the container. In this case, the soft feeling of the central portion hitting the skin or the like is not impaired, and the sheet strength does not decrease.
[0037]
In addition, in the case of a landmark, the shape of the sunken part can be freely designed according to the shape of the convex part of the pressure roller or the heating roller. The shape of the mark can be freely designed according to the arrangement of the heated opening needles to be formed. Therefore, it is possible to form not only a simple mark but a mark excellent in design.
