TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packaged wet tissue that can be pulled out and used one by one. More particularly, the present invention relates to a packaging wet tissue that can be taken out one leaf at a time when the wet tissue is pulled out and used together with a flexible packaging bag in a storage container.
[0002]
TECHNICAL BACKGROUND OF THE INVENTION
2. Description of the Related Art A wet tissue in which a water-resistant nonwoven fabric is impregnated with a water-based drug has recently been widely used as a body cleaning cloth and the like, and the frequency of use thereof particularly in childcare and nursing care has become extremely high.
Conventionally, a wet tissue is obtained by winding a nonwoven fabric having a break line into a nonwoven fabric in a cylindrical shape, storing the wound nonwoven fabric in a cylindrical container, pulling it out of an extraction hole provided at an upper portion of the container, and breaking the wet tissue. It was used while cutting at the point. However, the wet tissue stored in such a container has a large drawback resistance, and it is necessary to pull out the wet tissue with the other hand while fixing the container with one hand, which is very difficult to use. Was.
[0003]
There is a pop-up type wet tissue as a wet tissue that has improved such a point, and recently, this pop-up type wet tissue has been increasingly used in place of a conventional cylindrical wet tissue. In this pop-up type wet tissue, the nonwoven fabric cut in advance for each leaf is stored in a flexible bag in a state where the ends of the leaves are folded so as to overlap with each other, and the wet cloth folded in this way is used. The tissue is put in a storage box, and the wet tissue is formed so as to be able to be pulled out of the storage box with a resistance wall formed on the upper surface in a state in which the wet tissue is separated one by one. Therefore, in such a pop-up wet tissue, each leaf can be taken out independently by pulling out the wet tissue with one hand, and the next leaf is held in the resistance wall of the outlet of the storage container. Is desirable. However, when actually taking out the wet tissue, the next leaf may stick to the leaf of the wet tissue to be taken out, and two or more wet tissues may be pulled out. Such a phenomenon in which the leaves are successively extracted without separating the leaves when the wet tissue is taken out is generally called "slurry".
[0004]
When using a wet tissue, in many cases, one hand cannot be used freely, such as with one hand supporting an infant or cared person. If the next leaf is drawn out together with the wet tissue, it is difficult to use these separately.
The entrainment of the next leaf when taking out such a wet tissue (so-called "slurry") is not necessarily a problem that occurs when taking out a wet tissue, but when tens or hundreds of wet tissues are pulled out. It is a problem that occurs with a certain low probability, and it is not always clear what causes such wet tissue entrainment.
[0005]
Conversely, the wet tissue of the next leaf may not fall along with the wet tissue to be removed and may fall into the packaging bag before being held by the resistance wall. It is necessary to open the storage box and insert the leaf of the uppermost wet tissue into the outlet to hold it on the resistance wall. Such a drop of the wet tissue is also a problem that occurs with a certain low probability, and the cause of the occurrence is not always clear.
[0006]
Under such circumstances, there are a concept that the entrainment and detachment of the wet tissue is a problem of the resistance wall and a concept that the problem is a problem of the characteristics of the tissue. Various proposals have been made from these viewpoints.
For example, the present inventor believes that such entrainment of wet tissue is caused by the structure of the resistance wall. Therefore, the present inventor has proposed a structure having a resistance wall with little entrainment of wet tissue (so-called “slipping”). An application has already been filed (see Japanese Patent Application No. 2000-365448). By changing the structure of the resistance wall in this way, the frequency of entrainment of wet tissue is reduced, but it has not yet been possible to completely prevent them.
[0007]
In addition, based on the recognition that the entrainment or omission of the wet tissue is in the surface properties of the tissue, Japanese Patent Application Laid-Open No. 2000-509315 discloses that "a substrate and a liquid composition are provided. At least one of at least one surface of the panel having two opposing end panels-a leading edge panel and a trailing edge panel-each of which has a first surface and a second surface. Wherein the portion has either a coefficient of dynamic friction of 1 or less or a coefficient of static friction of 1.05 or less. "
[0008]
As described above, in the invention disclosed in this publication, the friction coefficient of the front and back surfaces of the wet wipe (wet tissue) greatly contributes to entrainment and detachment of the wet tissue, and the friction coefficient is set to a specific value. Thus, the above-mentioned entrainment and dropout are prevented.
The above-mentioned publication describes that the distribution of wipes is improved when folded and stacked, due to the friction coefficient of the edge surfaces of the wet wipes.
[0009]
If the friction coefficient of the portion where the tissue (wipe) overlaps is adjusted by, for example, embossing or the like, entrainment and detachment of the next tissue when the wet tissue is taken out can be improved as compared with the conventional wet tissue. However, the improvement effect is not always sufficient only by the friction coefficient.
[0010]
For example, the leaf of the wet tissue to be removed and the next leaf are changed not only by the friction coefficient of the overlapping wipe edge, but also by the surface tension of the chemical solution present in the overlapping portion. That is, when a liquid such as water is present between two wet tissues, the two wet tissues are stuck due to the surface tension of the liquid such as water, and the wet tissues in such a state are peeled off. It takes a lot of power. In particular, when irregularities are formed on the surface of the wet tissue by embossing or the like, the amount of liquid existing between the two tissues increases, and it becomes difficult to peel off the two wet tissues. On the other hand, when the amount of the liquid is small, the surface tension of the liquid hardly functions as an engaging force between the two wet tissues, and the surface state of the wet tissue becomes dominant.
[0011]
As described above, in the pop-up wet tissue, the entrainment of the next leaf when the wet tissue is taken out cannot be adjusted by a single factor, but is performed by a number of factors interacting with each other. Therefore, it was found that it was necessary to identify a number of factors relating to wet tissues from their mutual relationships.
[0012]
[Object of the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging wet tissue capable of reliably removing wet tissues one by one (one leaf at a time) from a storage box having a resistance wall formed in an opening.
In particular, the present invention is a water-impermeable wet tissue that can be securely held on the resistance wall without the wet tissue leaf to be taken out next being accompanied by the wet tissue to be taken out and accompanying withdrawal. It is an object of the present invention to provide a packaged wet tissue housed in a flexible bag.
[0013]
Summary of the Invention
The packaging wet tissue of the present invention is a packaging wet tissue containing an aqueous drug, which is folded so as to be able to be taken out one leaf at a time and stored in a water-impermeable packaging bag,
The wrapped wet tissue is composed of a woven fabric, a nonwoven fabric or paper to which fibers are bonded using a heat-fusible binder, and an aqueous agent, and the dry weight of the dried tissue is 40 g / m2. ² The softness of the dried tissue in a dry state measured by a handle ometer method is more than 15 g and less than 25 g, a herringbone pattern is formed on the tissue, and the packaged wet tissue is It contains 190 to 250 parts by weight of the aqueous agent with respect to 100 parts by weight of the dry tissue, and at least the end portion of the leaf of the wet tissue to be taken out overlaps at least the tip portion of the leaf of the wet tissue to be taken out next. And is housed in a flexible packaging bag body in a sealed state.
[0014]
That is, in the present invention, among the nonwoven fabrics forming the wet tissue, the basis weight of the dried tissue is 40 g / m. ² The following nonwoven fabric is used. However, the object of the present invention cannot be achieved simply by using a tissue having the above-mentioned basis weight. In the present invention, further, the softness of the dried tissue measured by a specific method is 15 g. It is necessary to exceed 25 g. A herringbone pattern is formed on the dried tissue, and the dried tissue preferably uses a hot-melt binder made of a polyolefin resin or the like as a binder used when forming a nonwoven fabric or the like.
[0015]
Further, 190 to 250 parts by weight of an aqueous drug is blended with 100 parts by weight of such a tissue, and this is mixed so that the vicinity of the end of the wet tissue of the previous leaf and the vicinity of the tip of the wet tissue of the next leaf overlap. It is folded and used in a water-impermeable and flexible bag.
As described in detail above, the basis weight, the softness, the type of the binder, a suitable type as a pop-up wet tissue formed with a pattern formed on the tissue, etc., and the amount of the aqueous drug mixed here is also the tissue. It is set within the range of 190 to 250 parts by weight for 100 parts by weight.
[0016]
The use of certain such tissues and the addition of a specific amount of aqueous agent to such specific tissues establishes that these elements work together to independently remove wet tissues. When a so-called one-leaf wet tissue is pulled out, the probability of occurrence of a so-called “slur” that is pulled out along with the drawn-out wet tissue is increased in a conventional pop-up wet tissue. Significantly lower than the rate.
[0017]

[0020]
The packaged wet tissue of the present invention is obtained by housing a plurality of folded leafy tissues and an aqueous agent in a water-impermeable and flexible packaging bag body.
FIG. 1 shows an embodiment in which the packaged wet tissue 10 of the present invention is stored in a storage container and used. That is, as shown in FIG. 2, the packaging wet tissue of the present invention comprises a plurality of wet tissues 14 each containing an aqueous solution and having each leaf independently folded, formed of a water-impermeable and flexible material. 1 shows a state in which the packaged wet tissue 10 of the present invention is housed in a sealed packaging bag body 12 in a sealed manner. The packaged wet tissue 10 can usually be formed with an opening 15 for taking out the wettissue, and is stored in the packaged wettissue storage containers 30 and 31 capable of storing the packaged wett together with the packaging bag 10. Used. Each of the storage containers 30 and 31 includes a bottom portion 31 and a dome-shaped container upper portion 30 formed such that a lower end portion is fitted into a concave groove formed in a peripheral portion of the bottom portion. Further, a take-out opening 20 for taking out a wet tissue is provided on the upper surface of the upper part of the dome-shaped container 30. The take-out opening 20 holds the drawn-out wet tissue 14 so as not to be drawn into the packaging bag body 12 and prevents the taken-out wet tissue 14 from being taken out together with the next drawn-out wet tissue. And resistance walls 22 and 23 for providing resistance for separation. The resistance walls 22 and 23 are formed so as to partition the resistance walls 22 and 23 by forming a plurality of slits 24 a and 24 b and 28 a and 28 b in the outlet 20. The resistance walls 22, 23 are composed of four tongue pieces 22a, 22b, 23a, 23b whose base ends are fixed by a plurality of slits 24a, 24b and 28a, 28b and whose front ends are free ends 25. The free end 25 is cut out to form a finger insertion portion 26 so that the first wet tissue can be picked out by a finger. The tongue pieces 22a, 22b, 23a, and 23b have flexibility that can be deformed when the wet tissue is taken out.
[0021]
The storage container outlet 20 has a lid 32 that is openable and closable so as to be open when used and closed so as to keep the packaging wet tissue storage containers 30 and 31 closed when not in use. ing. The lid 32 is normally urged in the opening direction by an elastic member 33 such as a spring body so that the lid 32 can be opened and closed with one touch when a wet tissue is to be taken out. The protruding locking piece 34 is locked to the opening button 35, and is formed such that when the opening button 35 is pressed, the opening button 35 is pushed up to jump up to expose the outlet 20.
[0022]
The resistance walls 22 and 23 formed in the outlet 20 hold the wet tissue securely until the next time it is taken out without the wet tissue 14 being drawn into the packaging bag, and are taken out. A resistance is provided to ensure that the next leaf wet tissue withdrawn to the resistance wall with the wet tissue leaf is separated from the previous leaf wet tissue. Therefore, if the resistance applied to the wet tissue from the resistance walls 22 and 23 is too large, the entrained wet tissue of the next leaf cannot pass through the resistance walls 22 and 23 and the next end will not pass. The leaf wet tissue falls into the packaging bag. On the other hand, if the resistance applied to the wet tissue from the resistance walls 22 and 23 is too small, the wet tissue to be removed is pulled out while being stuck near the end of the leaf, and may be separated from the next wet tissue. It becomes difficult to do. In other words, in order to take out one wet tissue, it is pulled out with the vicinity of the end of the next wet tissue attached to the vicinity of the end of this wet tissue.
[0023]
However, in the case of a pop-up type wet tissue, the wet tissue to be taken out is stuck with the wet tissue of the next leaf, pulled out to the resistance wall, held on the resistance wall, and then the wet tissue can be separated and taken out It is necessary that the overlapping wet tissues adhere to each other with some force. In order to completely prevent the occurrence of so-called "slipping", it is necessary to balance the resistance provided by the resistance wall and the force with which the wet tissue sticks to each other, which is the most difficult problem in a pop-up type wet tissue. It has already been known that the prevention of the occurrence of such "slipping" can be reduced to some extent by changing the shape of the resistance walls 22 and 23. Many proposals have already been made. In this application, as a configuration of the resistance walls 22 and 23 in which "slipping" is less likely to occur, a step is taken from a conventional two-dimensional resistance wall structure in which a pressing piece or the like is formed, as shown in FIG. A tongue-shaped free end 25 is formed in a three-dimensional shape at a portion where the wet tissue of the resistance wall, which is most in contact with the wet tissue, passes through the resistance wall. That is, by forming protruding portions 27a, 27b, 27c, and 27d protruding toward the inside of the storage container in the vicinity of the free end 25 formed in the shape of a tongue, and forming the take-out portion three-dimensionally, As shown in FIG. 5 and FIG. 6, when the protruding portions 27a, 27b, 27c, and 27d extending below draw the wet tissue, the free end 25 is bent upward and deformed. It comes into contact with the wet tissue P1 with a strong force. With such a configuration, it is possible to selectively increase the resistance of the wet tissue during withdrawal. Further, since the wet tissue is guided by the projections 27a, 27b, 27c, and 27d to the slits 24a and 24b provided at the center and is held by the slits 24a and 24b, the generation of "slipping" is prevented. Although significantly reduced, such a structure of the outlet 20 alone still generates "slipping" with a very low probability. The occurrence of such "slipping" has such a low probability that it cannot be prevented by improving the form of the resistance wall 20, and in order to further reduce the occurrence of "slipping", it is necessary to improve the wet tissue itself. is there. However, the wet tissue itself is used directly on the body, and its feeling of use is very important. Currently used wet tissues have a very good usability, and at the expense of a good usability of the wet tissue in order to further reduce the incidence of "slurs" that occur with a very low probability. Can not do it.
[0024]
In the present invention, in consideration of such a situation, the wet tissue itself is reviewed in order to further reduce the occurrence rate of “slipping” when taking out the wet tissue without deteriorating the usability of the wet tissue. Was.
As a result, by setting the properties of the wet tissue within a suitable range, the wet tissue of the next leaf can be added to the wet tissue to be taken out without impairing the excellent usability of the conventional wet tissue. It has been found that the probability of being accompanied and pulled out (that is, the probability of occurrence of “slipping”) can be further reduced.
[0025]
That is, the packaging wet tissue of the present invention is:
By adjusting the basis weight of the dried tissue and the softness of the dried tissue, using a specific binder as a binder constituting the tissue, and further adding the amount of the aqueous drug added to the tissue with a specific pattern to a conventional wet weight By making it slightly smaller than the tissue, the probability of occurrence of "slipping" in the wet tissue can be significantly reduced.
[0026]
The wet tissue of the present invention is usually formed from a woven fabric, a nonwoven fabric or a paper and an aqueous agent impregnated in the woven fabric, nonwoven fabric or paper. ² Or less, preferably 30 to 40 g / m ² And particularly preferably 33 to 38 g / m. ² Within the range. 40g / m ² When a non-woven fabric or the like having a thickness of more than 1 mm is used, the effect of reducing the probability of occurrence of “slipping” is unlikely to appear.
[0027]
Further, in the present invention, the softness of the dried nonwoven fabric measured by the handle ometer method (E method) needs to be more than 15 g and less than 25 g for the nonwoven fabric which is a dried tissue, and the softness is in the range of 16 to 24 g. , And particularly preferably in the range of 17 to 23 g. When the softness of the dried nonwoven fabric measured by the above method is within the above range, the generation of “slipping” in the packaged wet tissue of the present invention can be more effectively prevented. Also, the usability of the wet tissue is not different from the conventional one.
[0028]
FIG. 8 shows a measuring device used in the handle ometer method (E method) used here. In the handle ometer method (E method), three test pieces of 20 cm × 20 cm are sampled from the prepared sample, and the measurement direction is perpendicular to the slot (20 mm width) on the test table shown in FIG. Then, the blade of the ventilator adjusted so as to descend to 8 mm from the surface of the sample table is lowered, and when the test piece is pressed, the weight required for the blade to descend by 8 mm. In this test, measurement is performed in the vertical and horizontal directions at a position 6.7 cm (１ ／ of the test width) from one of the sides, and further, at different positions on the front surface and the back surface. The maximum value (weight (g)) thus obtained is read, and the average value of three samples is calculated. The value obtained in the present invention is a value measured by using a test piece of 20 cm × 20 cm and a slit width of 20 mm.
[0029]
In the case of a nonwoven fabric, for example, such a dry tissue is formed by bonding entangled portions of randomly arranged fibers with a binder. In the present invention, a hot-melt binder is used as the binder. In the present invention, it is preferable to use a heat-meltable binder having a relatively low melting point as the binder. As such a heat-fusible binder having a relatively low melting point, for example, a binder having a melting point in the range of 100 to 180 ° C. can be mentioned. In particular, examples of the binder suitably used in the present invention include polyolefin-based heat-fusible binders. Binders can be mentioned. The melting point of the polyolefin-based hot-melt binder is usually in the range of 100 to 160 ° C, preferably 120 to 150 ° C. The polyethylene / polypropylene-based hot-melt binder usually has a melting point in the range of 100 to 160 ° C, preferably 120 to 150 ° C, and the polyolefin-based hot-melt binder having such a melting point is used. By using this, the softness of the nonwoven fabric measured as described above can be easily set in the above-described preferable range.
[0030]
When a PP (polypropylene) / PE (polyethylene-based binder) is used as the polyolefin-based hot-melt binder, the blending weight ratio of both (PP / PE) is usually 1: 1.
Further, a herringbone pattern is formed on the nonwoven fabric forming the packaging wet tissue of the present invention. This herringbone pattern is specifically a cedar twill pattern as shown in FIG. 3, and in the present invention, for example, a herringbone pattern is formed on a receiving wire mesh used for receiving a nonwoven fabric when manufacturing the nonwoven fabric. It can be formed by using a receiving wire mesh. In the present invention, the width L of the ridge forming the herringbone pattern is preferably set in the range of 0.5 to 1.5 mm, particularly preferably in the range of 0.8 to 1.2 mm to form the herringbone pattern. By doing so, the effect of preventing the generation of “slurry” in the packaged wet tissue of the present invention appears more remarkably. That is, by forming a herringbone pattern in which the ridges having the width L are formed, the contact area of the overlapped wet tissue is reduced, and the leaf to be removed and the leaf are taken out together with the leaf. The joining force with the leaves is high enough to maintain the joined state until "slipping" does not occur and the leaf is securely held on the resistance wall of the storage container. Also, by forming the herringbone pattern in this manner, the nonwoven fabric tends to be bulky. That is, the nonwoven fabric constituting the packaging wet tissue of the present invention is 40 g / m2. ² Although it has the following basis weight, its feel is equivalent to that of a nonwoven fabric having a basis weight that is approximately 1.1 times or more the actual basis weight in terms of basis weight.
[0031]
Such a tissue (such as a nonwoven fabric) is cut into a substantially square of 15 to 20 cm × 15 to 20 cm, and the cut nonwoven fabric is folded in two as shown in FIG. 2 (a) or as shown in FIG. 2 (b). The sheet is Z-folded and stacked so that the vicinity of the end of the nonwoven fabric of the previous leaf and the vicinity of the tip of the next leaf overlap. FIGS. 2A and 2B schematically show a nonwoven fabric folded in two or Z, but the present invention is not limited to such a folding method. In the present invention, the prevention of the occurrence of "slipping" is based on the aspect in which the vicinity of the end of the previous leaf and the vicinity of the tip of the next leaf overlap and are stacked rather than the method of folding the nonwoven fabric as described above. This is largely due to the area of the overlap between the previous leaf and the next leaf. In particular, in the present invention, the generation rate of "slipping" can be reduced by superimposing the next wet tissue within a range of usually 5 to 25%, preferably 10 to 20% with respect to the entire area of the wet tissue. By overlapping the previous leaf and the next leaf in this way, the joint strength of the two leaves does not cause a “slipping”, and the two leaves are held until the tip of the next leaf is securely held on the resistance wall of the storage container. To the extent that the bonding state is not released. Since the vicinity of the end of the previous leaf and the vicinity of the tip of the next leaf are joined at the above-described area ratio, when this is viewed for one leaf nonwoven fabric, 10 to 50% of the total area is other It will overlap with the non-woven fabric of the leaves.
[0032]
The superposed and folded tissue (non-woven fabric) is impregnated with 190 to 250 parts by weight, preferably 200 to 220 parts by weight of an aqueous agent with respect to 100 parts by weight of the wet tissue to obtain a wet tissue. It becomes. The amount of the aqueous agent is also a very important factor in reducing the generation of "slurry" in the packaged wet tissue of the present invention. That is, the nonwoven fabric is impregnated with the aqueous drug, and the joining force of the two overlapping wet tissues depends largely on the surface tension of the aqueous drug contained in the wet tissue. Therefore, if the amount of the aqueous drug is outside the above range, the bonding strength of the folded leaves becomes unnecessarily high, and "slipping" is likely to occur. On the other hand, if it is less than the above range, the joining force of the folded leaves is insufficient, and the leaves to be taken out together with the leaves to be taken out fall before being held by the resistance wall of the storage container.
[0033]
As the aqueous agent used herein, water is a main component, a humectant, a fragrance, a bactericide, a surfactant, a polyhydric alcohol, a lower alcohol, an antihistamine, an antibacterial and antifungal agent, a pH adjusting agent, and a spasmolytic agent. An aqueous solution containing the above is used. However, some of the packaged wet tissues of the present invention are used directly on the skin, and the aqueous medicine of the wet tissue used for such a use directly on the skin does not contain a component having a skin irritating property. It is desirable. For example, it is desirable not to mix irritating components such as alcohol in a wet tissue that may come into contact with mucous membranes. On the other hand, in a wet tissue for the purpose of sterilization, disinfection, and the like, it is desirable to increase the blending amount of a lower alcohol that can be a sterilizing component, an antibacterial and fungicide, and the like.
[0034]
The wet tissue comprising the nonwoven fabric (tissue) folded and overlapped so that the end portion overlaps the end portion of the front and rear nonwoven fabrics and the aqueous agent as described above is water-impermeable and flexible. It is housed in a packaging bag having properties.
The packaging bag body 14 is formed of a polymer film such as polyolefin, polyester, polyamide, or the like, a metal-deposited polymer film, a laminated film in which a metal foil is laminated, and the like. It has the property of not permeating water so that the drug does not evaporate. Therefore, the film forming the packaging bag body may be formed of a single water-impermeable material, or a composite of a plurality of materials, for example, at least two layers of a plurality of materials are laminated. Laminated body. The thickness of the film forming such a packaging bag is usually in the range of 50 to 100 μm, preferably 50 to 80 μm. Further, it is preferable that the packaging bag is formed of a flexible film. That is, since the packaging wet tissue of the present invention is used by being stored in a packaging wet tissue storage container as it is in a packaging bag, it has flexibility so that it can be easily stored in this storage container. preferable. A packaging bag formed from the above-described film having the above-mentioned thickness has the flexibility required in the present invention. Further, since this packaging bag body can be easily formed by heat sealing, it is preferable to arrange a heat sealing layer on the inner surface side of the packaging bag.
[0035]
In such a packaging bag body, an opening for taking out the wet tissue contained therein can be formed. That is, as shown in FIG. 1, FIG. 5, and FIG. 6, when using the packaging wet tissue of the present invention, the first wet tissue 14 of the first leaf is pulled out from the opening 15 formed in the upper surface and stored. The packaging bag body needs the opening 15 because it is held by the resistance walls 22 and 23 formed in the container and the packaging wet tissue is stored and used in the storage container. However, before using this packaged wet tissue, that is, during storage, transfer, etc., the opening 15 as described above is not necessary in the packaged wet tissue, but rather, the aqueous drug constituting the wet tissue does not evaporate, In addition, it is desirable that the packaging wet tissue be hermetically sealed in order to prevent invasion of germs and the like from the outside.
[0036]
For this purpose, it is desirable that the opening formed in the packaging bag is completely closed before use, so that an opening through which a wet tissue can be taken out at the time of use can be formed. In the present invention, a break line is formed at a portion where the opening is to be formed on the upper surface of the packaging bag body, and the seal member 17 is adhered with an adhesive so as to cover the portion where the opening is to be formed at the opening line. When the sealing member adhered in this manner is peeled off, the packaging bag removing piece 18 of the portion where the opening is to be formed, which is formed on the packaging bag body 12 by a break line, is broken from the break line and transferred to the seal member 17. The opening 15 is formed in the packaging bag body. Here, the adhesive used for bonding the seal member 17 is such that when the packaged wet tissue is stored in the storage containers 30 and 31 or the storage containers 41 and 42 as shown in FIG. Since the seal member 17 is peeled and removed at the time of use, it is not necessary to have re-adhesiveness. On the other hand, when the packaging wet tissue 12 is used without being stored in a storage container, for example, in the case of a portable packaging wet tissue, the sealing member 17 is bonded so that the sealing member 18 can be used as a lid. A tacky adhesive having re-adhesive properties can be used as the adhesive.
[0037]
Then, by removing the seal member from the packaging bag, the opening 15 having a desired shape can be formed in the packaging bag 12. Here, the shape of the opening 15 formed in the packaging bag body 12 is not particularly limited as long as the wet tissue contained therein can be taken out, but is not more than 70% of the paper width of the contained wet tissue, preferably not more than 70%. It has a length of from 20 to 60% and a width from which the first wet tissue can be extracted, preferably from 0.1 mm to 70 mm, particularly preferably from 5 mm to 50 mm. By drawing the wet tissue from the opening (slit) 15 having such a length and width, the opening (slit) 15 itself formed in the packaging bag also serves as a resistance wall against the wet tissue to be taken out. In addition, it is possible to prevent the drawn-out wet tissue from falling back into the packaging bag, and to prevent the wet tissue held on the resistance wall provided with the storage container from falling off from the resistance wall. I do. In addition, since the slit (opening) 15 having such a width and a length is substantially filled with the drawn wet tissue, invasion of various bacteria from the slit (opening) 15 after opening is performed. In addition, there is an effect that the evaporation of the aqueous drug impregnated in the wet tissue can be effectively prevented.
[0038]
Further, the packaging wet tissue 10 of the present invention is used by being put in a storage container having a form as shown in FIG. 1, and this storage container is composed of a box-shaped container 41 having an open top as shown in FIG. It may be a storage container having a closed lid 42 for sealing the opened upper part, and having the outlet 20 and the lid 32 provided in the closed lid 42 to open and close the outlet 20 in a closed manner. The details of the storage container shown in FIG. 7 are substantially the same as those shown in FIGS. 1, 3, and 4. Also, the form of the resistance walls 22.23 preferably has the protruding pieces 27a, 27b, 27c, 27d. In particular, in the present invention, in addition to the above-exemplified form of the resistance wall, a resistance wall having a form described in the specification and drawings of Japanese Patent Application No. 2000-365448 is used to further reduce the probability of occurrence of “slipping”. It is possible. However, in the present invention, since the generation of “slipping” is prevented by the tissue (wedding cloth, nonwoven fabric, paper, etc.) itself and the amount of the aqueous agent forming the wet tissue, the form of the resistance wall is particularly limited. is not.
[0039]
The packaged wet tissue of the present invention can be used for wiping the body such as wiping infants and cared persons, cleaning toilets, water, maintenance of OA equipment, wiping cosmetics, etc. Can be used for various applications.

【The invention's effect】
The packaged wet tissue of the present invention has a specific weight of dried tissue, a softness of the tissue in a dry state measured by a handle-o-meter method, a herringbone pattern on the tissue, and a hot binder as a binder. It consists of a woven fabric, a nonwoven fabric or a paper formed using a fusible binder, and adjusts the amount of the aqueous agent with respect to the dry tissue so that the end portion of the leaf of the wet tissue to be removed and the wet tissue to be removed next. When the wet tissue is taken out by folding and storing in a flexible packaging bag body so that at least the tip part of the leaf overlaps, the taken-out wet tissue and the wet tissue of the next leaf are stored in a container, for example. The separated web is securely separated by a resistance wall Tissue in the wet tissue for the next leaf is drawn one after another stuck, the probability of occurrence of so-called "nozzle" is significantly reduced.
[0041]
In addition, the packaging wet tissue of the present invention has a significantly reduced probability of occurrence of so-called "slurry" as described above, but the wet tissue to be taken out next is securely held on the resistance wall of the storage container for the packaging wet tissue, It hardly occurs that the wet tissue is pulled back into the packaging bag.
[0042]
【Example】
Next, the packaged wet tissue of the present invention will be described in more detail with reference to examples of the present invention, but the present invention is not limited thereto.

Examples 1 and 2, Comparative Examples 1 to 4
As shown in Table 1, a nonwoven fabric was prepared using rayon fibers and a binder, and this nonwoven fabric was cut into a size of 15 × 20 cm. 90 sheets of the nonwoven fabric were Z-folded and stacked so that each leaf was overlapped by 13% with the previous leaf.
The nonwoven fabric thus stacked and a predetermined amount of an aqueous chemical with respect to 100 parts by weight of the nonwoven fabric are stored in a packaging bag, which is a laminate (thickness: 52 μm) of aluminum-deposited PET and polyethylene, and the storage opening is heat-sealed. Sealed. On the upper surface of the storage bag, an opening forming portion having a length of 6 cm and a width of 1.8 mm is formed by a wavy line, and a sealing member having a length of 10.5 cm and a width of 4.5 mm is acrylic-coated on the opening forming portion. The wet tissue was stored in a sealed state in a packaging bag by sticking with a system adhesive (no re-adhesiveness).
[0044]
By peeling off the sealing member from this packaging wet tissue, the packaging bag in the opening-related portion of the bag body was stuck to the sealing member and removed to form an opening. The packaging wet tissue having the opening formed therein was placed in a storage container as shown in FIG. 7, and the first wet tissue was pulled out of the packaging bag via the resistance wall, and held on the resistance wall of the storage container. The total length of the slits 24a and 24b in this container is 5 cm, which corresponds to 21% of the width of the wet tissue, and the width of the slits 24a and 24b is 21 mm. At the center of these 24a and 24b, a circular shape is formed for inserting a finger to draw out a wet tissue. Further, the protruding pieces 27a, 27b, 27c, 27d in this storage container each have a length of 1.24 cm and are formed to protrude 6 mm downward.
[0045]
In this manner, the wet tissues contained in the storage container were pulled out, and the number of sheets to be pulled out by connecting two or more wet tissues was measured.
The pull-out test as described above was performed five times for wet tissues having the same configuration, and the occurrence rate of “slipping” (wet tissue that was connected and pulled out) in one packaged wet tissue was determined. In addition, the rate of occurrence of wet tissue which was not held by the resistance wall and pulled back into the packaging bag was also determined. Further, the feeling of use of each wet tissue was evaluated by 15 panelists. Table 1 shows the results.
