DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for wet tissue having a so-called dispenser function, which can be used by dispensing wet tissue one by one.

[0002]

2. Description of the Related Art Conventional wet tissue storage containers are provided with a vertically elongated outlet at substantially the center of a rectangular gusset bag or the like, and a sealing lid covering the outlet is peeled off with an adhesive coated around the outlet. In this case, the wet tissue is taken out by removing the seal lid, the wet tissue is taken out, and the wet tissue is again adhered and sealed to keep the wet tissue in a moist state. In addition, when the inner bag such as a gusset bag containing a wet tissue is removed from the seal lid, and stored in a plastic molded container having a tightly closed lid, the wet tissue is taken out from the lid and used. There is also. In this case, recently, in order to cope with environmental problems, the molded container has been repeatedly used, and the inner bag has been replaced and used as a refillable container. On the other hand, when the outer box made of folded paperboard is raised, the inner bag stuck in advance on the inner surface of the outer box also expands at the same time, filling and sealing the wet tissue in the lined carton, and further covering the outer box with the carton sleeve Japanese Patent Application No. 9-143000 proposes a wet tissue storage container in which a take-out opening is opened in conjunction with pulling out an outer box from the sleeve, and the take-out opening is resealed when the outer box is pushed into the sleeve.

[0003]

However, a conventional wet tissue storage container in which a take-out opening is provided in a rectangular parallelepiped gusset bag-shaped soft packaging bag, and a seal lid is attached around the opening is convenient at first. Is good, but when the amount of wet tissue is reduced, the shape of the gusset bag is lost and it becomes difficult not only to take out the bag but also to reseal the seal lid. In addition, the peelable and sticky seal lid and its processing contribute to an increase in cost. Even when such a gusset bag or the like is refilled and used in a plastic molded container, the point that it becomes difficult to remove the wet tissue when the amount of the wet tissue is reduced remains unchanged. Further, even if plastic molded containers are used repeatedly, the initial purchase price must be increased, and consumers are demanding further cost reductions. Further, disposal of such a plastic container increases an environmental load. Therefore, Japanese Patent Application No. 9-14300
The proposal made in No. 0 solves the problem that the shape of the inner bag collapses by using a lined carton in which the inner bag is pasted in the carton in advance, but it is necessary to further use a carton sleeve. However, there still remains a problem that the total cost is increased due to the necessity of going through the production process of the lined carton. Further, in taking out the wet tissue, opening and closing the carton sleeve involves a problem in terms of usability. The present invention has been made in view of the above-described problems, and a wet tissue can be easily taken out without opening / closing an opening / closing lid or a sealing lid or the like, pulling out a sleeve, etc., as if using a normal box tissue. It is an object of the present invention to provide a wet tissue storage container and a method for manufacturing the same, which can be manufactured at low cost.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is an exploded view of the back of a carton blank for an outer box of a wet tissue storage container according to the present invention. As shown in FIG. 1, the carton blank 10 of the outer box of the wet tissue storage container according to the present invention has a side plate 3, a top plate 1, a side plate 3, a bottom plate 2, and a glue allowance 4 connected in this order via folding lines a to d. A folded flap F is connected to both ends of each part via folding lines e and f except for the glue allowance. At the approximate center of the rectangular top plate 1, there is provided a rectangular or elliptical elongated outlet forming plate 5 defined by a weakening line g formed by a perforation, a zipper cut line or the like. Also, on the back surface of the top plate 1, two film pieces 6A and 6B are placed outside the take-out opening forming plate 5 such that the edges overlap each other along the longitudinal center line of the take-out forming plate 5. It is firmly bonded in the bonding area S1 indicated by dots. The overlap width of the two film pieces 6A and 6B is preferably in the range of 3 to 15 mm.

FIG. 2 is an external view of the inner bag of the wet tissue storage container according to the present invention. The inner bag 20 of the wet tissue storage container according to the present invention is obtained by directly wrapping a plurality of stacked wet tissues with a soft wrapping material, and the shape of the inner bag 20 is the outer shape formed by the carton blank 10 described above. A gusset bag having a size substantially inscribed in the box and having a substantially rectangular parallelepiped shape as a whole is preferable, but may be a simple pillow packaging bag without a gusset. The inner bag 20 of the wet tissue storage container according to the present invention has a half cut 8 in advance in the longitudinal direction at the center of the surface where the vertical seal does not fit. The half cut 8 may be linear or dotted. It is preferable that the half cut 8 has such a strength that the center portion is easily broken just by abutting the fingertip against the center portion of the inner bag, and has a moisture retention property for wet tissue.

The wet tissue storage container 30 according to the present invention has the appearance as shown in FIG. 3A. The wet tissue storage container 30 is similar to the wet tissue storage container 30 shown in FIG. It is formed by wrap round with a carton blank 10 as shown. The term wrap round refers to a system in which the contents (in the present invention, the inner bag 20 containing the wet tissue) are wrapped in a carton blank and the box is made. Wet tissue storage container 30 according to the present invention
In this case, at the time of this wrap round, the half cut 8 of the inner bag 20 is provided at least in the adhesive area S2 (see FIG. 1) indicated by oblique lines provided around the take-out opening forming plate 5 of the carton blank 10. The surface side is strongly bonded. Such a partial bonding area is S
In addition to 2, it can be provided at any place of the carton blank 10. When the inner bag 20 and the outer box are bonded to each other in a plurality of bonding areas, the shape of the inner bag 20 is less likely to change.
Wet tissue can be stably taken out to the end.

FIG. 3 is an explanatory view of a procedure for using the wet tissue storage container according to the present invention. FIG. 3A is a perspective view of the wet tissue storage container 30 according to the present invention, in which a take-out opening forming plate 5 partitioned by a weakening line g appears on the top plate 1. The entirety of the ejection port forming plate 5 can be easily removed by breaking it from the end with a fingertip. FIG. 3B is a diagram showing a state in which the ejection port forming plate 5 is removed and the ejection port 7 is formed. A film piece 6 is inserted into the formed outlet 7.
A, 6B appear, the end pieces of which overlap each other longitudinally at the center of the outlet. The overlap functions to keep the wet tissue storage container 30 according to the present invention moisturizing even after the take-out opening forming plate 5 is removed, and further prevent dust from entering. The two tensioned film pieces are made of an elastic and flexible film, and the double part thereof has such a resistance that it does not hinder the insertion of the fingertip into the inside. To return to the position. FIG.
FIG. 3C shows a state in which a finger is inserted into the take-out opening 7 to actually take out the wet tissue WT, and FIG. 3D shows a state in which the end of the next sheet slightly comes out after taking out. This state differs depending on the method of folding the wet tissue WT. At the end of the use procedure, the slightly protruding end is pushed back with a finger into the outer box, and stored as shown in FIG. 3 (b).

In the wet tissue storage container 30 according to the present invention, unlike the conventional wet tissue storage container, the wet tissue WT can be used as a conventional ordinary box tissue without using an opening / closing lid or a sealing lid, unlike the conventional wet tissue storage container. It is very easy to use because it can be easily and easily taken out. In the wet tissue storage container 30 according to the present invention, the impregnation component (wet component) of the wet tissue cannot be completely prevented from volatilizing through the outlet 7 without the opening / closing lid or the seal lid. In the case of a polyhydric alcohol used for wipes, etc., the inventor has shown that within 2 months after opening, it is possible to impart sufficient moisture retention to a container with a lid. The result is confirmed. However, since the wet-tissue storage container 30 according to the present invention cannot be expected to have complete moisture-proof structure, it is preferable to use the wet-tissue storage container 30 in a shorter time than conventional ones. It is preferable to finish the slim storage container with a reduced thickness.

The wet tissue storage container 30 according to the present invention is a kind of bag-in-carton in which the inner bag is inscribed in the outer box as described above, and the manufacturing method comprises the following steps. It is. A step of preparing an inner bag in which a plurality of folded wet tissues are housed and have a substantially rectangular parallelepiped shape, and a half-cut line is provided at substantially the center of one surface thereof. A carton in which an elongated wet tissue take-out opening is provided at the center of the top plate, and two strip-shaped film pieces are affixed to a window so that edges are overlapped along a longitudinal center line of the take-out opening. Step of preparing a blank. The half-cut line of the inner bag is positioned so as to pass substantially at the center of the take-out opening of the carton blank, and the inner bag is wrapped around at least around the take-out opening to wrap around the carton blank. And packaging the inner bag.

First, there is provided a step of preparing an inner bag in which a plurality of folded wet tissues are provided to form a substantially rectangular parallelepiped shape, and a half-cut line is provided at substantially the center of one surface thereof. Can suitably use the horizontal pillow packaging machine that has been used so far. In the case where the inner bag 20 is a gusset bag, a gusset folding mechanism may be attached. FIG. 4 is an explanatory diagram of an interior process using a horizontal pillow packaging machine. As shown in FIG. 4, a long soft packaging material N supplied from a roll stand
Overlaps the wet tissue WT running in the same direction from the top, and a vertical seal is made at the bottom,
Finally, the inner bag 20 according to the present invention is formed by heat-sealing and separating in the cross direction with the flow. In this step, what is different from the usual process is that, in the center of the soft packaging material N,
That is, the half cut 8 is performed in advance. This half cut line 8 is provided substantially at the center of the surface of the inner bag 20,
Ultimately, it passes through the center of the outlet 7 in the longitudinal direction.

Next, an elongated wet tissue take-out opening is provided at the center of the top plate, and two strip-shaped film pieces are arranged so that the edges overlap along the longitudinal center line of the take-out opening. A step of preparing a carton blank with windows attached will be described. First, a printed board such as a coated ball having a basis weight of 250 to 350 g / m ² is punched into, for example, a blank shape shown in FIG.
This printing and punching is not different from the conventional method for manufacturing a carton blank, but at the same time as the punching, a process is performed such that an area serving as the central outlet 7 of the top plate 1 of the carton blank 10 is surrounded by a weakening line g. The weakened line g can be easily taken out through the perforated line or cut line 7
What is necessary is just what is formed. The structure of the carton blank 10 is not limited to the carton blank shown in FIG. 1 as long as the contents can be wrapped round.

FIG. 5 is an explanatory view of a window sticking step around the forming plate for the outlet of the carton blank. The long films A and B for window application supplied from the two rolls are guided by the vacuum roll 11 so that their both ends overlap each other, and cut into strips of a predetermined length by the cutter roll 13. As a result, the film pieces 6A and 6B are sent to a bonding portion below the vacuum roll 11 while being sucked by the vacuum roll 11. On the other hand, the carton blank 10 in which the adhesive is partially coated on the bonding area S1 by the gluing roll 14 is supplied to the attaching portion, and is pressed by the pressing roll 12 to be pressed into film pieces 6A and 6B.
Is attached to the window and discharged by the delivery conveyor.

Finally, the inner bag is positioned so that the half-cut line of the inner bag passes substantially at the center of the take-out opening of the carton blank, and the inner bag is wrapped round while being adhered at least around the take-out opening. This is a step of packing the inner bag with the carton blank, and this step can also use the equipment conventionally used as it is.
However, the gluing position at the time of the wrap round is at least the hatched area S2 around the take-out opening forming plate 5 of the carton blank 10, in which the carton blank 10 and the inner bag 20 are firmly bonded. is necessary. Other bonding positions may be appropriately selected, but it is preferable to select a plurality of positions such that the initial shape is maintained to the end while the inner bag 20 is inscribed in the inner surface of the outer box.

In each of the steps described above, the conventional equipment can be used as it is, except for the window sticking in the step, and the window sticking machine shown in FIG. Since it can be used only by making improvements, there is almost no need for initial capital investment. Further, a feature of the method for manufacturing a wet tissue storage container according to the present invention is as follows.
The process can be performed in parallel with the process, so that the production time is shortened compared to the lined carton method in which the inner bag is attached to a conventional carton and then the contents are filled, and the wet tissue Even when comparing the filling speed, the filling speed of raising the lined carton into a cylindrical body and inserting the wet tissue from one end and the filling speed by the wrap round method by the horizontal pillow packaging machine in the case of the present invention are not. In the case of the present invention, it is much faster. Therefore, according to the method for manufacturing a wet tissue storage container according to the present invention, the delivery date can be shortened.

The material used for the wet tissue storage container 30 according to the present invention is as follows:
Although it depends on the size of the outer box, the basis weight is usually 250 to 350 g /
Paperboard in the range of m ² is used, and a low-cost coated ball using recycled paper on the back surface can be suitably used for the paperboard. As the film used for the film pieces 6A and 6B for attaching windows, a low-density polyethylene film having a thickness of about 30 to 60 μm is sufficient, and a stretch film having further enhanced elasticity is more preferable. The soft wrapping material N for the inner bag 20 has excellent moisturizing properties and barrier properties of aroma components (often unscented), such as polyethylene terephthalate film 12 μm / aluminum foil 7 μm / polyethylene film 30 μm. The use of a laminate having a layer configuration is preferred.

[0017]

According to the present invention, instead of using the conventional opening / closing means such as an opening / closing lid and a sealing lid, resealing means is used instead of the opening 7 of the outer box of the bag-in-carton consisting of the outer box and the inner bag.
A piece of film is attached to the window so that the edges of the film overlap with each other along the longitudinal center line of the outlet 7, and the inner bag 20 provided with the half cut 8 at least around the outlet 7 is cut into the half-cut. 8 is adhered along the center line of the take-out opening 7, so that wet tissues can be easily taken out one by one with the feeling of a normal box tissue. In addition to keeping the moisture retention and hygiene properties during the use period, the plastic molded container is not used, so that the disposal property is good and the environmental load can be reduced. Furthermore, by adopting the method of wrap-around the filled inner bag with the carton blank, the process of preparing the inner bag and the process of preparing the carton blank can proceed in parallel, and the overwrapping with the soft packaging material N Since the speed of the wrap round of the inner bag 20 by the carton blank 10 is much faster than the filling speed of the conventional lined carton, no new equipment is required, so that the total manufacturing cost can be reduced and the delivery time can be shortened. Can be achieved.
