[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage bag for a wet towel for storing a storage sheet such as a wet sheet.

[0002]

2. Description of the Related Art For example, in a storage bag for storing a wet sheet such as a wet towel or the like, a bag body is formed of a sheet material made of synthetic resin, and a take-out port is formed above the bag body. An opening / closing lid that opens and closes is provided, and a stack of a plurality of wet sheets folded and stacked so that their edges are linked to each other is stored in the bag body. Is opened, and the wet towels in the bag body are pulled out one by one from the outlet. This kind of storage bag can easily open and close the take-out opening, the good sealing of the take-out opening after taking out the wet towel, and when pulling out the wet towel, make sure that the subsequent wet towel does not continue to come out of the take-out opening too much Is required. So, in the conventional storage bag, polyethylene,
A sheet member made of a synthetic resin sheet material such as polypropylene or polyester, or a sheet member made of a synthetic resin and a composite sheet material such as aluminum foil, and a mouth member having an outlet formed in a cross shape or the like, An opening / closing lid connected to this mouth member and closing the opening for opening and closing is integrally formed of a synthetic resin molded product, and the mouth member is welded to a bag main body made of a synthetic resin sheet material. Some are fixed by adhesion or the like.

[0003]

In a conventional storage bag, a mouth member and an opening / closing lid are integrally formed by a synthetic resin molded product, and the mouth member is fixed to a sheet material of a synthetic resin bag body. Therefore, it is necessary to manufacture the mouth member and the opening / closing lid by die molding, and the structure is complicated and the manufacturing cost is increased. is there. In addition, since the bag itself is made of synthetic resin sheet material and the mouth member and the opening / closing lid are molded products made of synthetic resin, the processing after using a wet towel is completed. There are drawbacks that are problematic. That is, since a synthetic resin molded article is used for the mouth member and the opening / closing lid, if the storage bag is incinerated after the use of the wet towel, a pollution problem of generating toxic gas will be caused. It is necessary to dispose of storage bags as non-combustible waste by a method other than incineration.

[0004] However, if the storage bag is dumped into a landfill or the like without incineration or the like, it is a molded article made of synthetic resin that is unlikely to deteriorate over a long period of time. It cannot be expected and will remain as it is for a long period of time, causing another pollution problem due to non-combustible garbage. Therefore, the conventional storage bag has a drawback that a pollution problem occurs at the time of disposal after use, regardless of whether it is incineration or dumping. In view of such conventional problems, the present invention has a simple structure, can be manufactured easily and inexpensively without using a molded product by die molding, and can be easily incinerated or discarded after use. An object of the present invention is to provide a storage bag for wet towels that can be used safely without inviting.

[0005]

FIG. 1 is a perspective view showing a sealed state of the storage bag, FIGS. 2 and 3 are cross-sectional views showing the sealed state of the storage bag, and FIG. 4 is an enlarged cross-sectional view of a main part. FIG. 5 is a perspective view showing the opened state of the storage bag, and FIG. 6 is a sectional view showing the opened state of the storage bag.
FIG. 7 is a perspective view showing a bag making step of the storage bag, and FIG. 8 is an enlarged perspective view showing the bag making step. 1 to 3, reference numeral 1 denotes a laminate of a wet sheet 2 such as a wet towel,
The laminate 1 is formed by laminating a plurality of wet sheets 2 folded in a zigzag shape in a substantially rectangular parallelepiped shape as a whole. As shown in FIG. 6, the ends of the upper and lower wet sheets 2 are overlapped over a predetermined range, and the ends of the front and rear wet sheets 2 are linked when the wet sheet 2 is taken out. It is laminated so that.

3 is a wet sheet 2 for storing the laminate 1
Body 6 having an outlet 5 for the wet sheet 2 formed on the upper surface 4 side and an opening 7 having substantially the same size as the outlet 5 and an upper surface of the bag body 6. 4, a protective film 9 covering the shape retaining plate 8 from the inside, a reinforcing film 10 attached to the outside of the upper surface portion 4 of the bag body 6, and an outside of the reinforcing film 10. Adhesive
A cover sheet 12 is attached to the bag body 6 so as to be openable and closable through the cover 11 and hermetically closes the outlet 5 of the bag body 6. The bag body 6 winds the composite sheet material 13 from the upper side of the laminate 1 to the front side via the rear side and the lower side so as to surround the laminate 1, and the wound end portion 13 a side of the bag body 1 via the adhesive 11. And a gusset part 14 and a crimping part 15 are formed on both left and right sides of the laminate 1 while being attached to the upper surface part 4 side, which is the winding start end part 13b.
Both ends of the bag body 6 are hermetically sealed on the crimping portion 15 side. At the approximate center of the upper surface 4 of the bag body 6, the bag body 6
A long hole-shaped outlet 5 is formed along the longitudinal direction. The take-out opening 5 only needs to be at a position where the wet sheet 2 in the bag body 6 can be easily taken out, and may be formed at a position other than the central portion, or may have a shape other than a long hole shape.

The cover sheet 12 is formed by breaking a pair of perforations from the edge of the overlapping portion 16 where the winding end portion 13a side of the composite sheet material 13 overlaps the winding start end portion 13b toward the front side of the bag body 6. The wire 17 is put in a J-shape, is formed integrally with the bag body 6 by the overlapping portion 16 of the composite sheet material 13 between the pair of breaking lines 17, and is peelable on the reinforcing film 10 via the adhesive 11. It is stuck. An adhesive is provided on the tip side of the cover sheet 12 so that the cover sheet 12 is picked up with a finger when peeling the cover sheet 12.
A knob 18 to which 11 is not applied is provided. Note that the break line 17 is formed by first reinforcing the cover sheet 12 with a reinforcing film.
Although perforations are formed at such a pitch that the composite sheet material 13 is easily broken when peeled from the sheet 10, a half cut may be used instead of the perforations.

The composite sheet material 13 is composed of a main sheet material 19 made of a natural material as shown in FIG. 4 and a main sheet material 19, as shown in FIG. 4, so that the storage bag 3 can be easily incinerated or discarded after use.
And a thin waterproof film 20 made of synthetic resin formed inside 19. The main sheet material 19 is made of a thin paper, a nonwoven fabric, or the like mainly using natural fibers such as wood pulp. Since the waterproof sheet 20 is made of a natural material such as paper for the main sheet material 19, it is necessary to prevent the moisture of the wet sheet 2 from penetrating into the main sheet material 19 or prevent the moisture of the wet sheet 2 from drying. In addition, it is for waterproofing the inside of the main sheet material 19. Then, the waterproof coating 20 is formed by extruding and coating a molten synthetic resin material such as a polyolefin material on one side surface of the main sheet material 19, or laminating a synthetic resin film such as an existing polyolefin film by lamination or the like. It is formed into a thin film by being attached. The waterproof film 20 may be made of any material having a predetermined waterproof effect, and its thickness is preferably as thin as possible so as not to cause a problem when the storage bag 3 is incinerated or disposed of. The material is not limited to a polyolefin-based synthetic resin material.

The shape-retaining plate 8 is for holding the shape of the bag body 6 in a flat shape so as to prevent wrinkles or the like from forming around the outlet 5 on the upper surface 4 side of the bag body 6. An opening 7 having the same size as the outlet 5 of the bag body 6 is formed in the center of the opening 7. This shape plate 8
In order to be able to incinerate or dispose of the storage bag 3 after use, a board material such as cardboard mainly made of natural fibers such as wood pulp obtained from natural materials such as wood pulp is used. When thick paper or the like is used for the shape retaining plate 8, the thickness varies depending on the size of the upper surface portion 4 side of the bag body 6, but for example, a thickness of about 0.5 mm to 3.0 mm is appropriate. .

Since the protective film 9 is made of a natural material such as cardboard for the shape retaining plate 8, the shape retaining plate 8 is protected from the inside so that the moisture of the wet sheet 2 does not penetrate into the shape retaining plate 8 side. It is for waterproofing. This protective film
9 is about 20μ (10μ to 3
(Approximately 0 μ or 50 μ) of a thin synthetic resin film.
It is fixed to the side by heat welding, adhesive bonding, or other methods. The shape retaining plate 8 is fixed inside the upper surface 4 of the bag body 6 by fixing the protective film 9 to the waterproof film 20 side of the composite sheet material 13. Protective film 9
Take out the wet sheet 2 in the bag body 6
When taking out from the bag, the take-out opening 5 of the bag body 6 and the shape retaining plate 8
An extraction hole 21 smaller than the opening 7 is formed. The take-out hole 21 is constituted by a cutting line 22 formed along the longitudinal direction of the take-out port 5 and the opening 7 and a small hole portion 23 formed at the center of the cut line 22 in the longitudinal direction. The take-out hole 21 is initially
When removing the wet sheet 2, the cutting edge 22 of the wet sheet 2 is pulled out by extending the cutting line 22 to both sides with the fingertip, and when the wet sheet 2 is removed, the leading end of the subsequent wet sheet 2 It comes out slightly from 21.

The reinforcing film 10 forms the bag body 6 with the composite sheet material 13 using the main sheet material 19 such as paper on the outside, so that when the opening 5 is closed, the bag body 6 is closed. This sealing film 10 can be sealed
This is for attaching the cover sheet 12 thereon via the adhesive 11. The reinforcing film 10 is made of a thin synthetic resin film of about 20 μ (about 10 μ to 50 μ), and a composite sheet material 13 is formed so as to correspond to the cover sheet 12.
Between the winding start end 13b and the winding end 13a.
6 is attached to the outside of the upper surface portion 4 by bonding or the like. The protective film 9 is larger than the size of the cover sheet 12, and the outlet 5 of the bag body 6,
An opening hole 24 having a size corresponding to the opening 7 is formed. A portion of the composite sheet material 13 other than the cover sheet 12 on the side of the winding end portion 13a is adhered on the reinforcing film 10 with an adhesive 11 interposed therebetween. Further, as the protective film 9 and the reinforcing film 10, synthetic resin films of the same material and the same thickness may be used, or synthetic resin films of different materials and different thicknesses may be used. However, in consideration of incineration or disposal of the storage bag 3, the protective film 9
It is desirable to reduce the thickness as much as possible within a range that does not impair the function of the reinforcing film 10.

In the case where the storage bag 3 is made while storing the laminate 1 of the wet sheets 2, the manufacturing process shown in FIGS. 7 and 8 is performed. In FIG. 7, reference numeral 25 denotes a material roll of the composite sheet material 13, and the composite sheet material 13 is fed out from the material roll 25, and is wound on the main sheet material 19 side of the composite sheet material 13 in the longitudinal feeding step A. At a predetermined position on one side in the width direction on the side of the starting end 13b, a reinforcing film 10 is adhered at a predetermined interval so as to correspond to the upper side of the laminate 1, and is adhered by another method.
After the composite sheet material 13 enters the horizontal feeding process B from the vertical feeding process A, the reinforcing film is placed on the waterproof coating 20 side at the position C.
A shape retaining plate 8 is supplied and set so as to correspond to 10, and as shown in FIG. 8, a long hole is formed so as to penetrate vertically through the shape retaining plate 8, the composite sheet material 13, and the reinforcing film 10. Then, an opening 5 is formed in the composite sheet material 13, an opening 7 is formed in the shape retaining plate 8, and an opening 24 is formed in the reinforcing film 10. In addition, shape retention plate 8
Is set on the waterproof film 20 side of the composite sheet material 13,
In order that this shape retaining plate 8 does not move on the composite sheet material 13,
The shape retaining plate 8 may be temporarily fixed on the composite sheet material 13 with an adhesive or the like.

Next, at a position D, a protective film 9 is supplied onto the composite sheet material 13 so as to cover the shape retaining plate 8, and the protective film 9 is applied to the waterproof film 20 of the composite sheet material 13 as shown in FIG.
Then, the shape retaining plate 8 is held by the protective film 9 and the composite sheet material 13 so that the shape retaining plate 8 does not move or hardly moves. In addition,
When the protective film 9 is fixed to the composite sheet material 13 by bonding or the like, it is desirable that the protective film 9 be adhered to the surface of the shape retaining plate 8. The protective film 9 may be formed with the take-out hole 21 after the fixation, or a method may be adopted in which the protective film 9 in which the take-out hole 21 has been formed is supplied onto the composite sheet material 13 and fixed. When the composite sheet material 13 is wound around the laminated body 1 at a position D before and after the supply of the shape retaining plate 8, when the composite sheet material 13 is wound around the laminated body 1, a winding start end 13b is formed.
The pressure-sensitive adhesive 11 is applied on the waterproof film 20 on the side of the overlapping portion 16 overlapping the side. After the application of the pressure-sensitive adhesive 11, at the position F 2, the edge side of the overlapping portion 16 of the composite sheet material 13 is notched in a concave shape at an appropriate interval to form a knob 18, and both sides of the knob 18 are formed. A pair of break lines 17 for the cover sheet 12 is inserted into the cover. Note that a composite sheet material in which the adhesive 11 has been applied to the polymerization section 16 in advance.
13 may be used. In this case, the adhesive
The trouble of applying 11 is not required, the bag making operation can be performed easily and quickly, and the speed of bag making can be increased.

On the other hand, at a position G immediately before and after the step of setting the shape retaining plate 8 on the composite sheet material 13 and piercing it, the wet sheet 2 is placed at a predetermined position on the waterproof film 20 of the composite sheet material 13.
Is supplied. After the supply of the laminate 1 and the fixation of the protective film 9 are completed, the composite sheet material 13 supplied with the laminate 1 is fed, and the winding start end 13b side of the protective film 9 of the composite sheet material 13 is laminated. 1 and the winding end 13a on the opposite side of the composite sheet material 13 is overlaid on the winding starting end 13b, and the protective film 9, the shape retaining plate 8 and the reinforcing film 10 are laminated. The laminate 1 is wrapped with the composite sheet material 13 so that the
16 is a winding start end 13b of the composite sheet material 13 via the adhesive 11.
Stick it on the side. At this time, the overlapping portion of the composite sheet material 13
Of the 16, the portion that becomes the cover sheet 12 between the pair of breaking lines 17 is adhered on the reinforcing film 10 via the adhesive 11.

When the winding end portion 13a is adhered to the winding start end portion 13b of the composite sheet material 13 on the upper surface portion 4 of the laminate 1, the composite sheet material 13 is wound on the laminate 1 in a cylindrical state. In a state.
Then, the laminate 1 and the composite sheet 13 are fed together in a state in which the composite sheet 13 is formed in a tubular shape, and the gusset portions 14 are formed on both sides of each laminate 1 in the longitudinal direction. The composite sheet material 13 is welded and cut on both sides to form a crimped portion 15, and a storage bag 3 in which the laminate 1 is stored in a sealed state is produced. When the wet sheet 2 stored in the storage bag 3 is taken out and used, the user grips the knob 18 side of the cover sheet 12 with a fingertip and pulls the cover sheet 12 toward the base side, as shown in FIGS. As shown in FIG. 6, both sides of the cover sheet 12 are broken at the break line 17 while the adhesive 11
Cover sheet 12 adhered on reinforcing film 10 through
Is peeled off.
The side is exposed and can be opened.

Next, the opening 24 of the reinforcing film 10 and the shape retaining plate 8
A fingertip is inserted into the outlet 5 of the bag body 6 through the opening 7 of the bag body, the cutting line 22 of the protective film 9 is spread on both sides, and the front end side of the wet sheet 2 is picked up as shown in FIG. Pull out from the take-out hole 21. At this time, if the previous wet sheet 2 is pulled out, since the edge of the subsequent wet sheet 2 is linked to the wet sheet 2, the subsequent wet sheet 2 subsequently comes out to the takeout hole 21 side. However, the take-out hole 21 of the protective film 9 is smaller than the take-out opening 5 of the bag body 6 and the like, so that resistance is applied to the subsequent wet sheet 2 by the protective film 9, so that the leading end of the subsequent wet sheet 2 When the side comes out from the take-out hole 21 upward, the preceding wet sheet 2 and the following wet sheet 2 are separated, and only one of the preceding wet sheets 2 can be taken out.

After the wet sheet 2 is taken out, the cover sheet 12 may be pasted again on the reinforcing film 10 on the front side of the bag body 6 via the adhesive 11, and the bag body 6
Can be sealed again by the cover sheet 12. The use of the storage bag 3 of this embodiment has the following advantages. That is, the main sheet material 19 using natural materials, that is, paper using natural fibers as the main material,
A composite sheet material 13 having a main sheet material 19 such as a nonwoven fabric and a waterproof coating 20 made of a synthetic resin inside the main sheet material 19 is used. The composite sheet material 13 is used to form the bag body 6 and the cover sheet 12.
And a cardboard or the like whose main material is natural fiber is used for the shape retaining plate 8. For this reason, when disposing of the used storage bag 3, problems such as pollution are less likely to occur regardless of incineration or disposal, and the storage bag 3 can be easily disposed.

For example, since the main components of the bag body 6, the cover sheet 12 and the shape retaining plate 8 are made of a natural material,
Even in the case of incineration, compared with the conventional storage bag 3 made entirely of synthetic resin material, less toxic gas is generated at the time of incineration, and the storage bag 3 is disposed of in landfills as dust. In this case, the main components of the storage bag 3 are not corroded or decomposed in a relatively short period of time, and do not remain as they are for a long period of time. A waterproof film 20 is provided inside the main sheet material 19, and a protective film 9 made of synthetic resin is provided.
And the reinforcing film 10 is used, but by securing a predetermined strength as the storage bag 3 with the main sheet material 19,
It is possible to make the thicknesses of the waterproof film 20, the protective film 9 and the reinforcing film 10 thin as long as their purpose is not impaired, and it is possible to minimize the amount of the synthetic resin material used. Therefore, the amount of toxic gas and the like generated during incineration can be extremely reduced as compared with the related art, and even when buried in soil or the like, the waterproof film 20 and the like can be deteriorated in a short period of time.

The bag body 6 and the cover sheet 12 are made of a main sheet material 19 such as paper mainly made of natural fibers. Bag body 6 and cover sheet by coating 20
Waterproofness of the wet sheet 2 can be ensured, and during storage for a certain period of time, the moisture of the wet sheet 2 penetrates into the main sheet material 19 side to damage the main sheet material 19, or the moisture of the wet sheet 2 escapes and the wet sheet 2 But does not dry out. Therefore, even if paper or the like mainly made of natural fibers is used for the bag body 6 and the cover sheet 12, this does not cause any problem. In addition, since the main sheet material 19 is provided with a waterproof coating 20 made of synthetic resin, the storage bag 3 is formed despite the fact that the main sheet material 19 is made of paper or the like mainly made of natural fibers. In some cases, the protective film 9 can be easily fixed by heat welding or the like using the synthetic resin waterproof film 20, and both ends of the bag body 6 can be easily sealed by heat welding or the like, facilitating bag making work. There are advantages that can be done.

When paper or the like is used for the main sheet material 19 of the bag body 6, the outer smoothness of the main sheet material 19 is lower than when a conventional synthetic resin sheet material is used. Due to the fact that the fibers on the side of the material 19 easily adhere to the adhesive 11 of the cover sheet 12, the adhesive force of the adhesive 11 of the cover sheet 12 is reduced, and the cover sheet 12 is adhered to the outlet 5.
The sealing performance when sealing is reduced. However, a reinforcing film 10 is placed on the outside of the bag body 6
Since the cover sheet 12 is adhered to the reinforcing film 10 via the adhesive 11, the cover sheet
With 12, the take-out port 5 side of the bag body 6 can be securely sealed to prevent the wet sheet 2 from drying, and even when the cover sheet 12 is opened and closed many times, a decrease in the sealing performance can be prevented as much as possible. .

On the side of the take-out port 5 of the bag body 6, there is a shape-retaining plate 8 having an opening 7 corresponding to the take-out port 5. The 5 sides can be kept flat. Therefore, when the cover sheet 12 is opened and closed, wrinkles are less likely to be formed around the outlet 5 of the bag body 6, and the cover sheet 12 can be securely adhered to the outlet 5 of the bag body 6. Moreover, although the cardboard 8 is made of a cardboard made of natural material, the protective film 9 covers the cardboard 8 from the inside.
The damage, deterioration, etc. of the shape retaining plate 8 due to the moisture in the wet sheet 2 can be prevented beforehand. In particular, the take-out hole 21 of the protective film 9 is made smaller than the opening 7 of the shape-retaining plate 8 so as to impart resistance to the subsequent wet sheet 2 when the wet sheet 2 is taken out. When the wet sheet 2 passes through the opening 7 of the plate 8, the wet sheet 2 comes into contact with the shape retaining plate 8 side,
Damage to the shape retaining plate 8 due to the moisture can be minimized.

Further, a shape retaining plate 8 made of cardboard or the like made of a natural material
This is covered with a protective film 9 and provided on the take-out port 5 side of the bag body 6, so that it is compared with the case of using a synthetic resin molded product in which the conventional mouth member and the opening / closing lid are integrally molded. As a result, the structure can be made simple and inexpensive, can be sealed using the cover sheet 12, the bulk of the bag body 6 on the side of the outlet 5 can be reduced, and the size can be reduced. In addition, in the bag making process of storing the laminated body 1 of the wet sheets 2 and forming the storage bag 3, the shape retaining plate 8 can be attached to the composite sheet material 13 constituting the bag body 6 by the protective film 9. In addition, it is possible to simplify the bag making process. Further, since the waterproof film 20 inside the main sheet material 19 is formed by coating a polyolefin-based molten resin or attaching a polyolefin-based synthetic resin film by lamination or the like, the main material is natural fiber. The waterproof film 20 can be easily formed inside the main sheet member 19 made of paper or the like, and the composite sheet member 13 used for the bag body 6 or the like can be easily and inexpensively manufactured.

As described above, one embodiment of the present invention has been described in detail, but the present invention is not limited to this embodiment. For example, when paper or the like having a smooth surface is used for the main sheet material 19, the reinforcing film 10 to be attached to the outlet 5 side of the bag body 6 can be omitted. In the embodiment, the bag body 6 and the cover sheet 12 are provided integrally, but the bag body 6 and the cover sheet 12 are separately configured,
A cover sheet 12 may be adhered from the outside to the outlet 5 side of the bag body 6. As in the embodiment, the bag body 6 side may be formed of the composite sheet material 13, and the cover sheet 12 may be made of the same synthetic resin sheet material as before.

When a natural material is used for the main sheet material 19 of the composite sheet material 13, any material may be used as long as the main material is a natural fiber obtained from the natural material. However, as the natural material, animal materials can be used in addition to plant materials such as wood. Further, the synthetic resin material used for the waterproof film 20 is not limited to the polyolefin type, and other synthetic resin materials can be used. However, when the storage bag 3 is incinerated, it is desirable to select a material that does not easily generate toxic gas or the like at the time of incineration and has a combustion temperature as low as possible.
This is the same for the protective film 9 and the reinforcing film 10.

Further, in the embodiment, a composite sheet material 13 having a waterproof film 20 such as a synthetic resin film is used inside a main sheet material 19 mainly composed of natural fibers, and the composite sheet material 13 is used for the bag body 6. , Constituting the cover sheet 12, but the composite sheet material 13 is other than a natural material, that is,
A composite sheet material in which a petrochemical synthetic resin sheet material and a synthetic resin film are bonded on the front and back, a composite sheet material in which a synthetic resin sheet material and an aluminum foil are bonded on the front and back may be used, or a synthetic resin may be used. A single sheet material may be used in place of the composite sheet material 13 made of steel. Therefore, the material of the bag body 6 and the cover sheet 12 does not matter. In the embodiment,
Although a plate made of a natural material such as cardboard mainly made of natural fibers is used for the shape retaining plate 8, a plate made of a synthetic resin may be used for the shape retaining plate 8.

In the embodiment, the wet sheet 2 is exemplified as the storage sheet, and the storage bag 3 for storing the wet sheet 2 has been described. However, the storage sheet may be a dry sheet, a chemical cloth, or the like. It can be applied to bag 3. Therefore, when storing a dry sheet, a chemical rag, or the like, the bag body 6 and the like can be made of paper or the like whose main material is natural fiber. When the respective wet sheets 2 are linked to each other, in addition to overlapping the upper and lower ends of the respective wet sheets 2, cutting can be performed for each wet sheet 2 of unit length on a raw sheet for the wet sheet. Other configurations such as providing perforations may be employed. The outside of the main sheet material 19 of the composite sheet material 13 may be subjected to appropriate printing over the whole or part thereof.
