Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention has two types of contents, particularly wet tissue and tissue paper (dry tissue paper).
, Or a portable pack containing two kinds of wet tissues having different scents and uses, and more specifically, it is possible to take out the stored wet tissues and tissue paper one by one separately. The present invention relates to a portable pack that can be repeatedly opened and sealed, especially for wet tissues that require sealing.

[Conventional technology]

Recently, a wet tissue obtained by impregnating a fiber material such as a non-woven fabric with a cleaning solution such as alcohol has been widely used as a material that can easily remove stains on hands and other bodies. The wet tissue in a tubular container is used at home or in a store, and a portable tissue in a small bag is also commercially available and widely used. In addition to removing stains on the body, wet tissues are also used for removing stains around kitchen stoves, refrigerators, and office automation equipment at companies.

Although wet tissues are convenient for removing dirt, their wetness limits their use and may not replace dust paper or dry tissue paper. Therefore, when going out, it is necessary to carry not only the wet tissue but also the tissue paper.

When I go out, I often forget to carry either a wet tissue pouch or a tissue paper pouch. Therefore, it is convenient to combine a wet tissue and a tissue paper into a portable pack.

Such a portable pack is disclosed in Japanese Utility Model Publication No. 57-60399. In the portable pack disclosed in this publication, a wet tissue and a tissue paper are accommodated in a bag-like pack made of a water-resistant synthetic resin film in a laterally parallel manner, and an intermediate portion between the wet tissue and the tissue paper is stored. And around the pack is heat sealed. Then, the whole seat is folded in half at the central seat portion.

In addition, the applicant of the present application, in Japanese Patent Publication No. 58-41842,
Three sheet materials are used, two of which are stacked on the bag body as one partition, and the dried content and the moist content are put between the sheets by sandwiching the partition sheet. I proposed a package with four sides sealed around the.

In addition, the applicant of the present application, in Japanese Patent Publication No. 59-46862,
Three sheets are used, two of which are stacked in a bag, one of which is used as a middle partition, and the middle partition sheet is sandwiched for 2
We proposed a package in which various kinds of wet contents were placed between sheets and the sheet material was sealed in all directions.

Further, the applicant of the present application has previously disclosed, in JP-A-61-203305, that the first contents (for example, a wet one) are stored in an inner bag having an outlet and a flexible opening / closing lid, and an outer bag. The outer bag sheet is provided with an opening so that the position of the opening of the outer bag sheet and the position of the opening / closing lid of the inner bag coincide with each other when the inner bag and the second contents are overlapped with each other. A method of manufacturing a package in which two types of articles are stored by wrapping the product to form an outer bag is disclosed.

[Problems to be Solved by the Invention]

The above-mentioned portable pack disclosed in Japanese Utility Model Publication No. 57-60399 is difficult to actually manufacture because of the structure as described above.

For example, in the case of producing a portable pack of Japanese Utility Model Publication No. 57-60399, a wet tissue and a tissue paper are placed side by side on a synthetic resin film on the lower side, and an upper side provided with respective outlets. A synthetic resin film is applied thereon, and heat-sealed into a bag shape around the center part between the wet tissue and the tissue paper and the periphery of the pack.

However, in such a manufacturing process, when the wet tissue and the tissue paper are placed side by side on the lower synthetic resin film, the liquid impregnated in the wet tissue exudes or flows around. Then, the tissue paper placed next to it gets wet and the commercial value is impaired.

Furthermore, the portion of the synthetic resin film to be heat-sealed may be wet to make heat-sealing difficult.

In addition, the periphery of the pack is relatively easy to heat seal, but sealing the middle part between the wet tissue and the tissue paper is not accurate when the position of the wet tissue or tissue paper is not correct at the time of heat sealing.
Can't heat seal well. Therefore, when feeding wet tissue or tissue paper onto the lower film, it must be placed accurately at a predetermined position, and the placed items may move during transportation until the sealing process. , You must be careful not to shift. Such a thing requires very delicate management and adjustment, and is actually very difficult. Therefore, continuous production of such a portable pack is practically impossible.

In addition, as another method of manufacturing the portable pack having the above-described structure, the three sides and the central part of the periphery of the pack are sealed in advance to form a bag with one open side, and a wet tissue and a tissue paper are respectively inserted into the bag from the opening. It is also conceivable to insert it into the bag and then seal the opening to form a portable pack.

However, in such a method, it is difficult to automatically insert a tissue paper or particularly a wet tissue into the bag, and continuous production is impossible. Therefore, the portable pack having the above-described structure is very expensive.

In the portable pack disclosed in Japanese Utility Model Publication No. 57-60399, since the entire periphery of the pack is sealed, the peripheral portion becomes hard, and when the pack is held by hand, the hard portion hits and is therefore difficult to hold. In addition, the size of the pack becomes larger than the contents and the necessary allowance by the size of the sealed peripheral portion and becomes bulky.

Further, in the portable pack disclosed in Japanese Utility Model Publication No. 57-60399, the entire pack is folded in half at the central seal portion when being carried. However, the wet tissue, the tissue paper, and the four thick films are overlapped with each other. Moreover, since the folded portion is easy to open, it becomes bulky as a whole. Therefore, a more compact portable pack is required.

To manufacture the package of Japanese Patent Publication No. 58-41842, a dried content is placed on one sheet material, a partition sheet material is placed thereon, and the wet content is further placed thereon. Is placed, and one sheet material is placed thereon, and the peripheral edges of the three sheet materials are heat-sealed. In this way, two kinds of contents are stacked and placed with the partition sandwiched therebetween, or three sheet materials are heat-sealed simultaneously with the two kinds of contents sandwiched, so that continuous production is performed. Is quite difficult to adjust. In particular, when the content is thick, the stacking is likely to be misaligned, so that the size of the sheet material has to be made considerably larger than the size of the content, and it is difficult to make a compact package.

Further, since the package of Japanese Patent Publication No. 58-41842 is a package in which three sheets of material are sealed around the four sides, three sheets of material are used when manufacturing the package from a continuous sheet. Film (sheet material) so that the position in the width direction (the position of the side edge in the longitudinal direction to be heat-sealed) does not shift
It is necessary to send out while aligning the positions. However, the film slightly expands and contracts due to the speed of each feeding roller, temperature, pressing force at the time of heat sealing, etc., and it is very difficult to accurately align the three sheet materials.

In the case of the package of Japanese Examined Patent Publication No. 59-46862, it is produced in the same manner as the package of Japanese Examined Patent Publication No. 58-41842 when it is produced from a continuous seal. There is a problem that the positions of the lid members to be accommodated also have to be matched, that is, the positions in the longitudinal direction of the film also have to be matched, and it is even more difficult to perform the positioning when the film is fed.

In order to manufacture the packages of Japanese Patent Publication No. 58-41842 and Japanese Patent Publication No. 59-46862, a delivery mechanism for delivering three sheet materials is required for each sheet material (3 Set required). Therefore, the device becomes complicated and large as a whole, and requires a large installation space.

In addition, since the packages of Japanese Patent Publication No. 58-41842 and Japanese Patent Publication No. 59-46862 are packages in which three sheet materials are sealed on all sides, the entire periphery of the package is hard and can be held by hand. The hard part hits when it hits, and it is difficult to hold. Moreover, the size of the package is larger than the sum of the size of the contents and the margin required to store the contents, by the size of the sealed peripheral portion,
It becomes bulky.

According to the manufacturing method of the package of JP-A-61-203305,
First, a step of manufacturing a product in which the first contents are housed and sealed in an inner bag having an outlet and a flexible opening / closing lid is required. Two
It is necessary to wrap the contents of and in an outer bag. Therefore, the manufacturing process becomes long and the production efficiency is not good.

Further, according to this method, the position of the opening of the outer bag sheet and the position of the opening / closing lid of the inner bag must be aligned with each other in the state where the inner bag and the second contents are overlapped with each other. Is relatively troublesome. Furthermore, since the inner bag itself is a complete sealed package, a package formed by storing two types of items can be sealed in the longitudinal direction when the inner bag is a pillow type bag, for example. Therefore, the thickness becomes thick and bulky, or when the inner bag is a four-sided seal, it becomes bulky because of the peripheral portion.

[Object of the Invention]

In view of the problems of the prior art as described above, the present invention,
It is made in consideration of various characteristics required for the package.

An object of the present invention is to provide a packaging body having two storage portions and storing the contents in the storage portions, respectively, using a long continuous film without continuously aligning a plurality of films. The present invention is to provide a method of manufacturing the same.

[Means for Solving the Problems]

A first method for continuously producing a package having two storage parts according to the present invention comprises a step of supplying a first content to a continuous long liquid-tight sheet at predetermined intervals, Fixing the side edges in the longitudinal direction of the sheet so as to wrap the contents at an intermediate portion in the width direction of the sheet;
The second contents so as to overlap the contents of the second contents, the step of wrapping the second contents with the sheet portion between the intermediate portion and the opposite side edge, and the two contents. Before and after the step of laterally adhering and cutting the sheet in the lateral direction.

A second method for continuously manufacturing a package having two storage parts of the present invention is a step of bending a continuous long liquid-tight sheet so that a cross section in the width direction has a W shape. And a step of supplying the first contents and the second contents from the two upward openings of the W shape at predetermined intervals between the folded sheets to corresponding positions, respectively, and Fixing at least one side edge in the longitudinal direction of the sheet so as to close at least one of the two W-shaped openings, and laterally adhering the two contents before and after, Cutting the sheet laterally.

As still another method, in each of the above-mentioned methods, a machine-like cutting notch for extending in the longitudinal direction is made at a position slightly closer to the center than the side edge of the sheet in advance, and the dried contents are wrapped in a sheet, Is characterized in that the side edges in the longitudinal direction of are fixed. According to these methods, in the finished package, the machine-like cutting slits extending in the longitudinal direction serve as outlets for the dried contents.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating the embodiments of the present invention.

FIG. 1 is a perspective view of an embodiment of a package manufactured by the method of the present invention as seen from one side, showing a state in which an opening / closing lid is open. FIG. 2 is a sectional view schematically showing a section taken along line II-II in FIG. FIGS. 3 to 9 are schematic sectional views similar to FIG. 2, showing different embodiments of the package manufactured by the method of the present invention.

In the package manufactured by the method of the present invention, for example, as shown in FIG. 2, the container main body has two accommodating portions, and one accommodating portion has a wet content (wet tissue) 21.
Is stored, and the other storage unit stores the contents (tissue paper) 22 in a dry state.

Alternatively, as shown in FIG. 6, contents (wet tissues) 21 and 21 'in different wet states are stored in two storage portions of the container body.

The container body in the present invention is a substantially flat bag body 1 composed of one flexible sheet 1 having liquid tightness (preferably air tightness). That is, all the wall portions that form the two storage portions of the container body are formed of one continuous liquid-tight flexible sheet 1.

In the first embodiment (see FIGS. 1 and 2) of the package manufactured by the method of the present invention, as shown in FIG. 2, the sheet 1 is folded in three (each part of the three-fold is on the first side). The edge portion 11, the intermediate portion 12, and the second side edge portion 13) are formed. The side edge 11a of the first side edge portion 11 is fixed to the sheet 1 at an intermediate portion 12 in the width direction of the sheet 1. In the drawing, the fixing points are schematically shown by black circles 14.

The second side edge portion 13 is folded back over the first side edge portion 11 (that is, on the same side as the first side edge portion 11), so that the first side edge portion 11 is formed so that the intermediate side portion 12 and the second side edge portion are Located between parts 13.

Both ends 15 in the longitudinal direction of the sheet 1 are fixed (sealed) to each other in an overlapping state of three folds.

Therefore, in the container body (bag) 1 of this embodiment,
The middle portion 12 and the second side edge portion 13 form an outer wall of the container, and the first side edge portion 11 divides the inside of the container into two to form two storage portions.

Adhesion 14 or both ends 15 of the side edge 11a of the first side edge portion 11
Can be fixed by a conventionally known method, for example, heat sealing, hot melt adhesive, ultrasonic sealing or the like.

In the first embodiment shown in FIG. 1 and FIG. 2, the contents 21 in a wet state are stored in the storage portion constituted by the first side edge portion 11 and the intermediate portion 12, while the first Side edge
The contents 22 in a dry state are stored in another storage portion constituted by 11 and the second side edge portion 13.

In order to take out the contents 21 in the wet state, the opening 2 or a notch for forming the opening 2 (for example, a perforation-like notch, still In FIG. 10, it is indicated by reference numeral 9) is an intermediate portion 12
It is provided in. The opening 2 or the notch for separating may be a closed loop such as a circle, an ellipse, a rhombus, or a track, or an open loop such as a U-shape.

Further, an opening / closing lid 4 for covering the opening 2 or the notch for separation so as to be repeatedly opened and sealed is provided in the intermediate portion 12 in the storage portion.

A pressure-sensitive adhesive layer 6 that is almost entirely coated is formed on a surface of the opening / closing lid 4 that is in contact with the bag body 1 (hereinafter referred to as an inner surface).

The opening / closing lid 4 may be simply attached to the bag body 1, but preferably, the opening / closing lid 4 is fixed so as not to come off from the bag body even when the opening / closing lid 4 is opened. To do this, for example,
One end of the opening / closing lid 4 is cut into the bag body 1 by heat sealing, an adhesive or the like, or a cut is made from both side edges, or a cut is made in the center of the end of the opening / closing lid 4, or an opening is formed. The separation notch for forming 2 may be a U-shaped closed loop.

When the cutout for forming the opening 2 is provided, the bag body 1 surrounded by the cutout (intermediate portion 1
2) Part 5 When the package is first used, the bag 1
Then, as shown in FIG. 1, it is attached to the pressure-sensitive adhesive layer 6 on the inner surface of the opening / closing lid 4. This separated part 5
When the opening / closing lid 4 is closed, the cover 2 substantially covers the opening 2 and serves as a seal for closing the opening 2, that is, a closing seal 5. The opening / closing lid 4 is attached to the bag body 1 by the pressure-sensitive adhesive layer 6 around the closing seal 5 to seal the opening 2 of the bag body 1.

In addition, the closing seal 5 is not formed from a part of the bag body 1 as described above, but the opening portion 2 is provided in the bag body 1, and
Another sheet piece having the same size and shape as the opening 2 may be attached to the pressure-sensitive adhesive layer 6 so as to close the opening 2 and used as the closing seal 5.

As described above, when the closing seal 5 is used, the closing seal 5 covers the opening 2. Therefore, even when the opening / closing lid 4 is closed, the contents 21 stored in the bag 1 are not covered with the pressure-sensitive adhesive layer 6.
The contents 21 are kept in a clean state without being in direct contact with. In addition, when the pressure-sensitive adhesive layer 6 is formed only on the peripheral portion of the opening / closing lid 4, the closing seal 5 may be omitted.

In the other storage portion constituted by the first side edge portion 11 and the second side edge portion 13 which store the dried contents 22, the contents 22
In the dry state, since the airtightness is not particularly required, the opening / closing lid is not provided. In this storage part, as shown in FIGS. 1 and 2, the opening 20 for taking out the contents 22 in the dry state is fixed at both ends 15 of the second side edge portion 13.
However, since the side edge 13a is not sealed and remains open, the open portion becomes the opening 20.

In the present invention, the main material of the sheet 1 constituting the liquid-tight bag body 1 is a synthetic resin such as polyethylene, polypropylene, polyester, polyvinyl chloride, polyamide, cellophane, or acetate, a film or the like alone or in each case. Examples include film lamination and composite materials. Further, depending on the type of contents, a composite material obtained by laminating the above various films and an aluminum foil can be used.

The sheet 1 is preferably made of a material that can be heat-sealed on one side or both sides of the sheet. Alternatively, it is also possible to use an adhesive having hot-melt properties and melting at a temperature lower than that of the sheet 1 applied to at least the portions corresponding to both ends of the bag 1.

The opening / closing lid 4 may be made of the same material as the sheet material used for the sheet 1.

As for the form of the opening / closing lid 4, it is preferable that the opening / closing lid 4 has an area larger than that of the opening 2, and the shape thereof is circular, elliptical, rectangular, or track-shaped to provide a decorative effect.

The pressure-sensitive adhesive layer 6 provided on the inner surface of the opening / closing lid 4 is preferably acrylic, rubber-based, polyester-based, polyolefin-based, resin, etc., and its coating method is roll coating, knife coating, spray coating, or the like. It is preferable to use any of the above methods.

If the opening / closing lid 4 is made of a transparent sheet material, the state of the contents and the opening 2 can be seen well from the outside.

Further, the opening / closing lid 4 is provided with a projecting handle portion 7 at the end opposite to the fixed end portion 3 so that the user can easily open / close the opening / closing lid 4. It is preferable that the pressure-sensitive adhesive layer 6 is not applied to the handle portion 7 as shown in the drawing.

As a method for fixing the opening / closing lid 4 and the bag body 1, heat sealing,
Any method such as ultrasonic bonding, high frequency bonding, or a bonding method using an adhesive is possible, and it is appropriately selected depending on the material of the bag body 1. Alternatively, the opening / closing lid 4 which is notched from both sides or which is notched at the center may be attached to the bag body 1 so as not to be peeled off from these notches.

Next, a second embodiment (see FIG. 3) of the package manufactured by the method of the present invention will be briefly described.

This embodiment is the same as the first embodiment described above except for the following points. That is, in this embodiment, the side edge 13a of the second side edge portion 13 is
Is different from the first embodiment in that it is lightly bonded 16 (lightly heat-sealed or uses a weak adhesive) so that it can be separated by hand. In the drawings, a triangle 16 represents a state in which the pieces are lightly bonded 16 so that they can be separated by hand. Then, at the time of use, the side edge 13a is manually separated to form an opening 20 for taking out the dried contents.

When the side edge 13a of the bag body 1 is lightly attached to the side edge 13a so that it can be separated by hand as described above, the side edge 13a is not used by the consumer during use.
By removing a, it becomes an outlet, so that the consumer can confirm for the first time.

Next, a third embodiment (see FIG. 4) of the package manufactured by the method of the present invention will be briefly described.

This embodiment is the same as the first embodiment described above except for the following points. That is, in this embodiment, the side edge 13a of the second side edge portion 13 is
Is fixed to the intermediate portion 12 by heat sealing, an adhesive, or the like (the fixed portion is indicated by a black circle 17), and the perforation cutting notch 18 (in the drawing, which serves as an outlet for the dried content 22). The second side edge portion is schematically represented by a dotted line)
13 is different from the first embodiment in that it is provided. Then, at the time of use, the cutting notch 18 is cut by hand to form an opening 20 for taking out the dried contents.

If the tear-off notch 18 of the bag 1 is to be manually teared off as described above, the consumer will use the tear-off notch 18 to tear it off during use, so the consumer should use it for the first time. You can check for yourself.

Next, a fourth embodiment (see FIG. 5) of the package manufactured by the method of the present invention will be briefly described.

This embodiment is the same as the above-described third embodiment except for the following points.

That is, in this embodiment, unlike the third embodiment, the contents 22 in a dry state are stored in the storage portion constituted by the first side edge portion 11 and the intermediate portion 12, and the first side edge portion 11 and the first side edge portion 11 The contents 21 in a wet state are stored in a storage portion formed by the two side edge portions 13. And the contents 21 in a wet state
The opening that serves as a take-out port and the opening / closing lid 4 that covers the opening are the second
On the side edge portion 13, on the other hand, there is provided in the intermediate portion 12 a cutting notch 18 for taking out the dried contents 22.

Since the structure is different as described above, when the package of the third embodiment is manufactured, the wet contents 21 are wrapped before the dry contents 22 are wrapped, and the fourth contents shown in FIG. When manufacturing the package of the embodiment, the contents 22 in the dry state are wrapped before the contents 21 in the wet state are wrapped.

Next, a fifth embodiment (see FIG. 6) of the package manufactured by the method of the present invention will be briefly described.

This embodiment is the same as the above-described third embodiment except for the following points.

That is, in this embodiment, unlike the third embodiment, not only the contents 21 in a wet state are stored in the storage portion constituted by the first side edge portion 11 and the intermediate portion 12, but also the first side edge portion A storage portion formed by 11 and the second side edge portion 13 also stores the wet contents 21 '. An opening serving as an outlet for the wet contents 21 'and an opening lid 4 for covering the opening are provided in the second side edge portion 13.

Thus two different contents 21 and 2 in wet condition
The package of this embodiment is convenient for storing 1 '. In particular, when manufacturing this package, two opening / closing lids 4
Since it suffices to stick the sheet on the same surface of the sheet 1, the two opening / closing lids can be easily aligned with each other, and therefore the manufacturing is simple.

Next, another embodiment (see FIGS. 7 to 9) of the package manufactured by the method of the present invention will be described.

The main difference between these embodiments and the first to fifth embodiments described above is the folded state of the sheet 1.

That is, in the first to fifth embodiments described above, the sheet 1 is folded in three, whereas in the embodiments of FIGS. 11 to 13, the sheet 1 has a cross section W. It is bent in four in a letter shape, the middle part 12,
12 'is between the first side edge portion 11 and the second side edge portion 13,
It is folded in an inverted U shape and serves as a partition of the container body 1.

Therefore, in the container body (bag) 1 of each embodiment shown in FIGS. 7 to 9, the first side edge portion 11 and the second side edge portion 13 constitute the outer wall of the container, and the intermediate portions 12, 12 ′ Divides the interior of the container into two parts, one storage part is constituted by the first side edge part 11 and the intermediate part 12, and the other storage part is constituted by the second side edge part 13 and the intermediate part 12 ′. .

Since both ends of the bag body 1 are laterally sealed as in the embodiment shown in FIG. 1, an intermediate portion 12 folded in an inverted U shape is formed.
And 12 'form another housing 23 having one side open.

This storage section 23 is convenient for storing the used contents 21 or 22. Alternatively, it is convenient to put other things such as a handkerchief.

Other points are the same as those of the respective embodiments described above. The embodiment shown in FIG. 7 is similar to the embodiment shown in FIG. The embodiment shown in FIG. 8 is similar to the embodiment shown in FIG. The embodiment shown in FIG. 9 is similar to the embodiment shown in FIG.

When manufacturing the package of each of the examples of FIGS. 7 to 9, after folding the sheet 1 into a substantially W shape, the two contents are simultaneously or temporally moved back and forth as described later.
It is supplied between two sheets of the letter upward (actually upward, downward, or sideways) so as to be wrapped between the sheets. In this case, in the case of the embodiment shown in FIG. 7, if the position of the side edge 13a of the second side edge portion 13 is slightly displaced, the seal 14 can be easily formed.

Also, the fixing points 14 and 17 are two side edge parts during manufacturing.
Conveniently, it is formed by simultaneously sealing 11 and 13.

Next, one embodiment of the method for manufacturing a package of the present invention will be described with reference to FIGS. 10 and 11. The packaging body shown in FIG. 3 is manufactured by this embodiment.

The continuous sheet 1 to be the bag 1 is delivered from the sheet roll 1A by an appropriate delivery device such as a roller.

Next, a notch (perforation) 9 for separating to form the opening 2 with an appropriate shape is formed by the punching machine 32 at substantially the center in the width direction of the sheet 1.

Separately, an opening / closing lid 4 having an adhesive layer formed thereon is prepared by applying a pressure-sensitive adhesive made of an acrylic ester-based or rubber-based material on one surface to a region wider than at least the opening 2. For example, in a state where the open / close lid 4 is attached to the continuous release paper 33, this is used as the release paper roll 33A, and is delivered by an appropriate delivery device such as a delivery roller, and the open / close lid 4 is fed from there.

The opening / closing lid 4 is peeled off from the release paper 33, and the opening / closing lid 4 is covered with the pressure-sensitive adhesive so that the portion of the opening / closing lid 4 coated with the pressure-sensitive adhesive covers the cutting notch 9 of the sheet obtained in the above step. The sheet 1 is attached by a sticking machine (for example, a label sticking machine) 35 or manually.

When one end of the opening / closing lid 4 is fixed to the sheet 1 as a bag by heat sealing or the like, one end of the opening / closing lid 4 may be fixed to the sheet 1 by means of a heat sealer or the like after the above-mentioned step although not shown. . This step may be omitted if the opening / closing lid 4 is fixed by another method such as a cut or an adhesive, or if the opening / closing lid 4 is simply attached to the sheet 1.

The sheet 1 having the notch 9 for separation and the opening / closing lid 4 obtained as described above may be continuously fed to the next step as it is by an appropriate feeding device such as a feeding roller. Then, it is once wound on a bobbin to form a roll 1B, and thereafter, as shown in FIG. 11, the roll 1B is fed to the next step by an appropriate feeding device such as a feeding roller.

When the sheet 1 is continuously supplied to the next process, it is necessary to match the timings of the previous process and the next process, but the winding process and the winding device are unnecessary, which is convenient. Also,
When the sheet 1 is once wound and then supplied to the next process, the timing of forming the notch 9 for separation and the attachment of the opening / closing lid 4 and the supply and packaging of the contents 21 and 22 in and after the next process. This is convenient because it is not necessary to match the timing, and the apparatus can be made compact because the apparatus up to the previous step and the apparatus after the next step can be installed separately.

Next, a sheet-shaped fiber material (wet tissue) obtained by impregnating or applying synthetic materials, papers, woven fabrics, non-woven fabrics, cotton, gauze, foamed sheets and the like to the sheet 1 obtained in the above step is applied. 21 is supplied by the supply device.
In this case, the sheet-shaped fibrous material 21 is placed on the portion 2 to be an opening, on the surface opposite to the surface of the sheet 1 to which the opening / closing lid 4 is attached. That is, the sheet-shaped fiber material 21 is placed so that the opening / closing lid 4 is exposed in the finished product.

As the supply device, an appropriate device that has been conventionally used for conveying and supplying the objects to be packaged in the packaging machine may be used.
As such a device, for example, a conveyor device configured to transfer the objects to be packaged one by one onto the packaging sheet at the same timing while transferring the objects to be packaged in a substantially horizontal direction at a constant interval by a conveyor such as a chain with an attachment. Or
A material handling device that stacks items to be packaged vertically and grips the topmost or bottommost items to be picked up one by one, a conveyor that transfers the items to be packaged in a substantially horizontal direction, and holds the items to be packaged. Then, there is a combination with a material handling device that takes out one by one.

Next, the former 36 guides the one side edge portion 11 of the sheet 1 so as to cover the wet sheet-shaped fiber material 21. Then, the side edge 11a of the first side edge portion 11 is fixed to the intermediate portion 12 of the sheet 1 along the longitudinal direction thereof, that is, sealed (fixing portion 14). For fixing, heat sealing with a heat sealer 37, bonding with an adhesive (preferably a hot melt adhesive), ultrasonic sealing, or other appropriate means may be used.

Sheet-like fiber material 21 in a wet state with the first side edge portion 11 interposed therebetween
A sheet-shaped fibrous material (tissue paper) 22 in a dry state is supplied onto the above by a supply device. As the feeding device, a conventionally used device may be used similarly to the above-mentioned feeding device for the sheet-shaped fibrous material in a wet state, and the structure thereof is the same as the structure of the feeding device.

In the above description, after the side edge 11a of the first side edge portion 11 is fixed to the sheet 1, the sheet-shaped fibrous material 22 in the dry state is first
The sheet-shaped fiber material 22 in a dry state is placed on the first side edge portion 11 by reversing these steps, and then the side edge of the first side edge portion 11 is placed. 11a may be fixed to the sheet 1.
