Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a package for packaging two types of items, particularly one item that requires hermetic sealing and the other item that does not require hermetic sealing. This relates to a manufacturing method.

[Conventional technology]

BACKGROUND ART Traditionally, a so-called katsutoban, which is adhesive tape with gauze attached, has been often used to treat abrasions, cuts, etc., and is useful because it can easily treat wounds. It is especially useful for treating scrapes and cuts in children.

However, children often fall and get injured while playing outdoors. In such cases, there is often mud attached to the wound, and even if you are holding a katsutoban, you cannot apply the katsutoban to the wound until the mud has been wiped off or disinfected. .

Therefore, for the treatment of injuries outdoors, it would be convenient to have a portable product that combines a cutlet with disinfectant-impregnated gauze, absorbent cotton, etc., but such a product is not yet commercially available.

The applicant of the present application previously developed an enclosure bag that can store two types of items and at least one of the items can be opened and sealed repeatedly (see Japanese Patent Publication Nos. 59-46862 and 58-41842). This enclosing bag is made by stacking three sheets and heat-sealing the entire circumference of the sheets with the item to be stored between the sheets. An outlet is provided on the outer sheet, and this outlet is covered with an open/close lid coated with a pressure-sensitive adhesive.

[Problem that the invention seeks to solve]

This known encapsulation bag itself consists of two types of items (particularly one item impregnated with liquid).
Although it is suitable for storing things, it is relatively difficult to manufacture. In other words, when serially producing this enclosing bag, the first item is placed on the first sheet, the second sheet is further supplied on top of the first sheet, and the second item is placed so as to overlap the first item. Place the item on top of the second sheet, feed the third sheet over it, and place the item on top of the first sheet.
- Two types of items are sandwiched between the two spaces between the third three sheets, and the overlapping three sheets are heat-sealed to produce an enclosing bag.

However, in such a manufacturing process, it is not easy to supply items between each sheet. Furthermore, it is not easy to supply the third sheet and convey it to the heat sealing process while these items are stacked on top of each other with the second sheet in between, without collapsing. Furthermore, since three sheets are heat-sealed at the same time, it is difficult to select a film, set conditions such as temperature and pressure during heat-sealing, and manage and adjust them.

Additionally, if one item is impregnated with liquid, the liquid may ooze or flow into the surrounding area during transportation, wetting the other item and damaging its product value, or preventing heat sealing. It may make it difficult to heat seal by wetting the area where it should be applied.

Further, in the above-mentioned encapsulation bag, a relatively thick sheet is used since the sheet must be airtight, and all three sheets are made of the same material in order to facilitate heat sealing. Therefore, the cost of the sheet is relatively high.

The present invention aims to solve the problems of the conventional methods as described above. In other words, it is easy to supply the items to be packaged, it is easy to set and control conditions such as temperature and pressure during heat sealing, and there is no risk of heat seal failure even if one of the items is impregnated with liquid. The purpose is to provide such a method. Furthermore, the present invention provides a method that allows the use of relatively inexpensive sheets.

[Means for solving problems]

According to the present invention, the above problems are solved by the following three methods.

One method is to prepare an inner bag in which the first content is sealed, a second content, and a continuous sheet for packaging the inner bag and the second content, and the inner bag is made of an airtight sheet. and has a take-out port for taking out the first content or a cut for forming the take-out port, and a flexible opening/closing lid that covers the take-out port or the cut; Form openings or cuts for forming openings at predetermined intervals for taking out the contents of the container, and forming openings or cuts for taking out the second contents at locations parallel to the openings or cuts. a notch is provided for forming the opening formed in the continuous sheet, and the surface of the inner bag opposite to the opening/closing lid contacts the second content, and the opening/closing lid of the inner bag matches the opening formed in the continuous sheet or the notch for forming the opening. In this way, the inner bag and the second bag are attached to the continuous sheet.

Wrap the continuous sheet with the inner bag and the second contents overlapping each other, overlap both edges of the continuous sheet in the longitudinal direction, and supply the second contents. In addition to forming an outlet for the
It is then cut in the transverse direction and separated into individual packages.

Yet another method includes preparing an inner bag in which a first content is sealed, a second content, and first and second continuous sheets for packaging the inner bag and the second content, and The inner bag is made of an airtight sheet and has an outlet for taking out the first contents or a notch for forming the outlet, and a flexible opening/closing lid that covers the outlet or notch. , in the first continuous sheet, openings or cuts for forming openings for taking out the first contents are formed at predetermined intervals, and in the second continuous sheet, openings for taking out the second contents are formed at predetermined intervals; an ejection opening or a notch for forming an ejection opening, the surface opposite to the opening/closing lid of the inner bag is in contact with the second contents, and the opening/closing lid of the inner bag is formed in the first continuous sheet. providing an inner bag and a second content between the first and second continuous sheets so as to coincide with an opening or a cut for forming the opening; the inner bag and the second content; sealing both edges of the first and second continuous sheets in the longitudinal direction in an overlapping state with each other, and also sealing them in the lateral direction, and then cutting them in the lateral direction to separate them into individual packages. It is characterized by

〔Example〕

Fig. 1 is a process diagram showing an embodiment of the manufacturing method of the present invention, Fig. 2 is a perspective view of an embodiment of the package manufactured by the method of the present invention, and Fig. 3 is the package of Fig. 2. FIG. 4 is a sectional view taken along the - line of the package shown in FIG. 2 (however, the cut for forming the outlet is not cut away); FIG. 6 is a plan view showing one side of the package shown in FIG. 2, and FIG. 6 is a back view showing the opposite side to that shown in FIG.

First, the inner bag 1 containing the first content 3 and the second content are prepared.

The inner bag 1 is made of an airtight sheet, and seals and stores the first contents 3.
It has a take-out port for taking out or a notch for forming the take-out port, and a flexible opening/closing lid 5 that covers the take-out port or notch.

FIG. 1 shows an embodiment of the method for manufacturing the inner bag 1. As shown in FIG. In this embodiment, a press machine 101 forms perforations 13 in an airtight sheet 10 for forming an inner bag 1 at a location that will serve as a take-out opening. is attached to the airtight sheet 10 so as to cover the perforation-like cuts 13 of the airtight sheet 10.

As shown in FIG. 4, a pressure-sensitive adhesive 51 is applied to the surface of the opening/closing lid 5 that contacts the airtight sheet 10, leaving a tab 52. Then, preferably, as shown in FIG. 1, one end of the opening/closing lid 5 is fixed to the sheet 10 using a heat sealer 103.

The first content 3 is placed on the perforation-like cut 13 on the side opposite to the side to which the opening/closing lid 5 is attached of the airtight sheet 10, and the guide member 10
4. The first contents 3 are processed by a bag making machine consisting of a center heat sealer 105 and a lateral heat sealer 106.
An inner bag 1 in which the first contents 3 are sealed and cut into single bags by cutting in the transverse direction with a cutter 107.
get.

The airtight sheet may be a single or composite material of a synthetic resin film such as polyethylene, polypropylene, polyamide, polyester, or polyvinyl chloride, or a composite material of these and aluminum foil or the like.

In the above-mentioned embodiment, when the opening for taking out the first contents 3 is opened as shown in FIG. is attached to the pressure-sensitive adhesive 51 and separated from the main body of the inner bag 1 to release the first contents 3.
An outlet is formed.

Instead of a closed-loop perforation, the airtight sheet may be completely punched out to form the outlet, or a U-shaped perforation cut may be provided. U
In the case of a letter-shaped perforation-like cut, when the opening/closing lid is opened, the part surrounded by the U-shaped perforation is separated from the main body of the inner bag 1, but its end remains continuous with the main body. .

Another type of inner bag may be manufactured, for example, as follows.

An open loop (eg, U-shaped) cut is formed in the airtight sheet. A piece of sheet having a closed loop perforation and coated with a pressure sensitive adhesive on one side is applied to the inner surface of the inner bag over the open loop cut of the inner bag. 1st on top of the sheet piece
Place the contents of the container and wrap it to obtain an inner bag. During use, when the open loop part of the inner bag is lifted, the part of the sheet piece surrounded by the closed loop is lifted together with the part surrounded by the open loop notch of the inner bag, and is removed from the sheet piece. be separated. The part surrounded by the closed loop of the sheet piece is torn off, and the mark serves as an outlet for the first contents, and the part surrounded by the open loop notch of the inner bag serves as an opening/closing lid.

Although the inner bag 1 shown in FIG. 1 is of a pillow type, it may also be a three-sided seal type or a four-sided seal type bag.

Note that the inner bag 1 is not limited to the embodiment described above, but is made of an airtight sheet, and has an outlet for taking out the first contents sealed therein, or a notch for forming an outlet. Any known enclosing bag may be used as long as it has a flexible opening/closing lid that can be opened repeatedly and its outlet or incision is covered with a flexible lid that can be opened repeatedly.

Preferably, the second content is approximately the same size as the first content so that it can be easily stacked on top of the first content. If the second content is to be used in small individual pieces, such as katsutoban, instead of packaging each piece individually in advance, it may be possible to separate the pieces with perforations, etc., and then wrap them in a continuous package. It is best to keep it in good condition and package it. In addition, if the second content is a sheet-like material such as tissue paper, the first
It is a good idea to fold the contents into an appropriate size according to the size of the inner bag.

Next, as shown in FIG. 1, the inner bag 1 is
and the second contents 4 are packaged. That is, the continuous sheet 20 for the outer bag 2 is pressed by the press 201.
Openings 21a for taking out the first contents are formed at regular intervals.

At the same time, a perforation-like cut 26 extending in the longitudinal direction of the continuous sheet 20 in parallel with the opening 21a.
will be established.

The inner bag 1 is placed on the continuous sheet 20. In this case, the inner bag 1 is placed so that the opening/closing lid 5 is on the lower side, and the opening/closing lid 5 is aligned with the opening 21a formed in the continuous sheet 20.

Then, the second contents 4 are supplied onto the inner bag 1.

The continuous sheet 20 is guided by a guide member 202 and wraps the inner bag 1 and the second contents 4 in a superimposed state. Then, the longitudinal side edges 24 of the continuous sheet 20 are sealed together by the heat sealer 203. Next, the horizontal heat sealer 20
4, the outer bag 2 is also sealed in the lateral direction to form a heat-sealed portion 23, thereby forming a continuous outer bag 2.

The cutter 205 is used to cut the package in the lateral direction at or near the heat-sealed portion 23 to obtain individual packages 7.

The material of the continuous sheet 20 for the outer bag 2 mentioned above is a single material or a composite material such as a synthetic resin film or cellophane similar to that mentioned above for the inner bag 1, and does not require particular airtightness. , a sheet-like material can be used thinner than the inner bag 1.

Moreover, instead of forming the perforation-like notches 26 that extend continuously in the longitudinal direction in the continuous sheet 20, a suitable shape for taking out the second contents 4, for example, over a predetermined length, is provided at a location parallel to the opening 21a. A perforation or slit-like outlet may be formed.

Note that when supplying the inner bag 1 and the second contents 4 to the continuous sheet 20, the inner bag 1 is supplied first in FIG. 1, but conversely, the second contents are supplied first. The article 4 may be placed on the perforation-like cut 26 at a location corresponding to the opening 21a, the inner bag 1 may be placed on top of the second contents 4, and the article 4 may be wrapped with the continuous sheet 20.

The package 7 manufactured as described above is the first
An inner bag 1 containing contents 3, and a second inner bag and a second inner bag.
It consists of an outer bag 2 containing contents 4 and contents 4, and will be explained in more detail based on FIGS. 2 to 6.

Surface of inner bag 1 on the side that contacts outer bag 2 (outer surface)
11 has a perforation-like cut 13, and an opening/closing lid 5 made of a flexible sheet-like material is provided so as to cover this perforation-like cut 13.

The opening/closing lid 5 has the inner surface (that is, the surface in contact with the surface 11 of the inner bag 1) except for the knob 52.
A pressure-sensitive adhesive 51 is applied to the opening/closing lid 5 and the inner bag 1 can be repeatedly pasted and closed using this pressure-sensitive adhesive 51.
It is removable.

The perforation-like cut 13 is covered by the opening/closing lid 5 before use, but once the opening/closing lid 5 is peeled off, a portion 14 surrounded by the perforation 13 is covered with the inner bag 1.
It is separated from the main body and stuck to the pressure-sensitive adhesive 51 of the opening/closing lid 5 as shown in FIG. 11a.

When the perforation-like cut 13 is formed in this way, it is possible to confirm that the consumer has opened the package for the first time when using the package. Note that instead of the perforation-like cut 13, a hole may be made in the inner bag 1 to serve as an outlet for the first contents 3.

As shown in FIG. 4, the inner bag 1 and the second contents 4 have the second contents on the inner surface 12 of the inner bag 1 (the surface opposite to the surface 11 where the perforations 13 are formed). The objects 4 are stored in the outer bag 2 in a state where they are in contact with each other and overlap each other.

As shown in FIGS. 2 and 5, the surface 21 of the outer bag 2 that is in contact with the outer surface 11 of the inner bag 1 has a
An opening 21a is formed at a location corresponding to the opening/closing lid 5. Therefore, by opening the opening/closing lid 5 of the inner bag 1 at this opening 21a as shown in FIG. 2, the first contents 3 can be taken out from the inner bag 1 through the outlet 1a.

As shown in FIGS. 3 and 6, the surface 22 of the outer bag 2 opposite to the surface 21 has a perforation-like cut 26 that forms an outlet for taking out the second contents 4. be. Although a take-out opening may be formed instead of the perforated cut 26, it is preferable to use the perforated cut because it allows the consumer to confirm that the package is opened for the first time before use.

The outer bag 2 has both ends 23 and one longitudinal end 24
The bag is made using a heat-sealed three-sided seal.

Since the inner bag 1 has airtightness and liquidtightness,
The inner bag 1 is suitable for storing things impregnated with liquid, things with smells and fragrances, etc. as the first contents 3 to be stored in the inner bag 1. For example, gauze or absorbent cotton impregnated with a disinfectant solution, wet tissue impregnated with a cleaning solution, etc. can be stored.

The second contents 4 to be stored in the outer bag 2 are preferably ones that have been dried and do not have a strong odor or aroma. For example, it can store cutlets, dry tuna, etc.

When using such a package, if the first contents 3 are to be used, lift the opening/closing lid 5 by holding the knob 52 of the opening/closing lid 5 to open the outlet 11a of the inner bag 1, Take out the first contents 3 from there, and then open and close the lid 5 again to open the takeout port 11.
Just cover a. When the second contents 4 are to be used, the package may be turned over to the opposite side, the perforated cut 26 is cut open to serve as an outlet, and the second contents 4 can be taken out from there.

7 to 12 show various modifications of the outer bag 2. FIG.

FIG. 7 shows the outer bag 2 in contact with the outer surface 11 of the inner bag 1.
FIG. What is shown in this drawing is a press machine 201 that forms a perforated cut 27 and a continuous cut 28 instead of punching out the opening 21a. A closed loop is drawn by these two types of cuts 27 and 28.

During use, pinch the continuous notch 28 with your hand,
When lifted along the perforation-like cut 27, the portion surrounded by the closed loop is separated from the main body of the outer bag 2, and an opening is formed, resulting in a state similar to that shown in FIG. Therefore, if the opening/closing lid 5 of the inner bag 1 is opened from the opening, the removal port 11 is opened from the inner bag 1.
The first contents 3 can be taken out from a.

When the outer bag 2 is formed with perforation-like notches 27 like the one shown in FIG. Therefore, the inner bag 1 does not need to have a sealing function.

Therefore, it is suitable for storing the inner bag 1 by making a hole in the inner bag 1 instead of using the perforated notch 13 as shown in FIG.

FIG. 8 shows the outer surface 1 of the inner bag 1, similar to FIG. 7.
1 is a plan view showing a surface 21 of the outer bag 2 in contact with the outer bag 1. FIG.
The drawing shown in FIG. 8 is the same as that shown in FIG. 7, in which a perforation-like cut 27 is formed with a continuous cut 28 instead of punching out the opening 21a using a press 201. However, unlike the one shown in FIG. 7, two types of cuts 27 and 28 form a substantially U-shaped loop. Therefore, the part surrounded by this open loop is a perforation-like cut 27.
Even if it is separated, it is not separated from the outer bag 2 main body.
Furthermore, the continuous cut 28 in the one shown in Fig. 7 was made relatively long to make it easier to separate the closed loop part, but in the one shown in Fig. 8, it was made short enough to fit a finger.
Make sure you don't accidentally open it.

In addition, in the embodiment shown in FIG. 8, unlike the first embodiment, a four-sided seal is obtained by heat sealing the entire periphery 23 and 24 of the outer bag 2, and this manufacturing method is similar to the 19th embodiment.
This will be described later with reference to the drawings.

FIG. 9 is a back view showing another embodiment of the outer bag 2, and FIG. 10 is a sectional view taken along the line - in FIG. 9. The outer bag 2 of this embodiment is shown in FIGS. 2 to 6.
Unlike the three-sided seal outer bag 2 shown in the figure, it is formed into a pillow type. That is, in the process shown in FIG. 1, the positions of the openings 21a and perforations 26 formed in the continuous sheet 20 are slightly shifted in the width direction of the continuous sheet 20,
The seal in the longitudinal direction is placed near the center of the outer bag 2 in the width direction.

Therefore, in this embodiment, the heat-sealing portions 23 at both ends and the heat-sealing portion 31 in the longitudinal direction are provided on the surface 22 on the side that contacts the second contents 4. On the surface 22, a heat-sealed portion 31 in the longitudinal direction is located at a location slightly offset from the center, and a perforation-like cut 26 forming an outlet for taking out the second contents 4 is provided in the center. .

Although FIG. 10 shows an opening 21a provided on the opposite surface 21 of the outer bag 2, as in the first embodiment,
As shown in Figures 6 and 7, perforations 27 and 2
8 may be provided.

Fig. 11 is a process diagram showing another embodiment of the manufacturing method of the present invention, Fig. 12 is a back view of a package obtained by this method, and Fig. 13 is a diagram taken along the - line in Fig. 12. It is a sectional view of the ivy.

In this embodiment as well, the inner bag 1 and the second contents 4 are prepared in the same way as in the embodiment shown in FIG.

Openings 21a for taking out the first contents are then formed in the continuous sheet 20 for the outer bag 2 by a press 201 at approximately the center in the width direction of the continuous sheet 20 and at regular intervals in the longitudinal direction. This opening 2
In place of 1a, perforation-like cuts or cuts 27 and 28 as shown in FIGS. 7 and 8 may be formed.

An opening 2 formed in the continuous sheet 20 so that the opening/closing lid 5 of the inner bag 1 is on the lower side;
1a, the continuous sheet 20
Place inner bag 1 on top.

Then, the second contents 4 are supplied onto the inner bag 1.

The continuous sheet 20 is guided by a guide member 202 and wraps the inner bag 1 and the second contents 4 in a superimposed state. At this time, both longitudinal edges of the continuous sheet 20 are overlapped with each other, but are not heat-sealed.

Next, the outer bag 2 is closed laterally using a lateral heat sealer 204 to form a heat seal portion 23.
form.

It is laterally cut at or near the heat-sealed portion 23 by the gutter 205 to obtain individual packages 7.

The outer bag 2 manufactured in this way is of a pillow type, as shown in FIGS. 12 and 13, but only has both ends 23 heat-sealed and there is no heat-sealed portion in the longitudinal direction. On the side 22 in contact with the second content 4, the longitudinal edges 32, 33 simply overlap, as is clearly shown in FIG. Therefore, the edge 32,
The gap 33 serves as an outlet for the second content 4, and the second content 4 can be taken out from the gap.

Similar to FIG. 10, FIG. 13 shows an opening 21a provided on the opposite surface 21 of the outer bag 2, but as shown in FIGS.
7 and 28 may be provided.

When manufacturing a package as described above, the outer bag 2
By tightly wrapping the inner bag 1 and the second contents 4, the opening/closing lid 5 of the inner bag 1 and the opening 21a or the notches 27, 28 of the outer bag 2 will not be misaligned.

However, the opening/closing lid 5 of the inner bag 1 and the opening 21 of the outer bag 2
In order to completely prevent misalignment between the inner bag 1 and the notches 27 and 28, a means for fixing the inner bag 1 and the outer bag 2 may be provided, for example, as described below.

In the embodiment shown in FIG. 14, both ends 2 of the outer bag 2
A part of the heat seal part 3 and a part 11b of the heat seal part at both ends of the inner bag 1 are adhered by heat sealing. For example, when making the outer bag 2 with the inner bag 1 and the second contents 4 wrapped,
The width of the heater that heats the surface 21 of the outer bag 2 is made wider, and both ends 11b of the surface 11 of the inner bag 1 are also heated. The surface 21 may be bonded to the surface 21 by heat.

As another fixing method, the outer bag 2 may be of a shrink package type. As shown in FIGS. 15 and 16, first, a heat-shrinkable film is used as the material for the outer bag 2, and the inner bag 1 is
and the second contents 4 (Fig. 15), and then,
The package is heated in a shrink tunnel to heat shrink the outer bag 2 (FIG. 16). In this way, the outer bag 2 comes into close contact with the inner bag 1 and the second contents 4, so that the inner bag 1 and the outer bag 2 do not become misaligned.

In this case, it is preferable to use a uniaxially stretched film so that the film shrinks only in the width direction or longitudinal direction of the package. In this way, the outer bag 2 contracts only in one direction, so when the outer bag 2 is contracted, the opening 21a or the notches 27, 2
The position of 8 remains almost constant. Therefore, even when the outer bag 2 is deflated, the opening/closing lid 5 of the inner bag 1 and the opening or notch of the outer bag 2 can be aligned more reliably.

FIG. 17 is another embodiment for explaining the fixing means, and FIG. 18 is a sectional view taken along the - line in FIG. 17. In this embodiment, an inner bag 1 and an outer bag 2 are bonded together using an adhesive (for example, a pressure sensitive adhesive) 6. The adhesive 6 is attached to the surface 11 of the inner bag 1 and the surface 2 of the outer bag 2.
It may be provided anywhere as long as it is in contact with the inner bag 1 or the outer bag 2.
Preferably, the opening or notch 27,2 in the outer bag 2
Adhesive may be applied by printing or the like immediately before or after forming the opening 21a or the notches 27, 28 using the press 201 so as to be located around the opening 21a or the notches 27, 28.

FIG. 19 shows a process diagram of an embodiment of the manufacturing method of the present invention for manufacturing a package sealed on all sides as shown in FIG. 8.

In this embodiment as well, the inner bag 1 and the second contents 4 are prepared in the same way as in the embodiment shown in FIG.

The outer bag 2 is made up of two continuous sheets, and the first continuous sheet 20 is formed with an opening 21a by a press 201 for taking out the first contents.
are formed approximately at the center of the first continuous sheet 20 in the width direction and at regular intervals in the longitudinal direction. This opening 2
In place of 1a, perforation-like cuts or cuts 27 and 28 as shown in FIGS. 7 and 8 may be formed.

Place the inner bag 1 on the first continuous sheet 20 so that the opening/closing lid 5 of the inner bag is on the lower side and the opening/closing lid 5 is aligned with the opening 21a formed in the first continuous sheet 20. Place.

Then, the second contents 4 are supplied onto the inner bag 1. A second continuous sheet 30 is guided onto this.

The second continuous sheet 30 has a second continuous sheet corresponding to the opening 21a formed in the first continuous sheet 20.
For example, a perforation-like cut 36 extending in the longitudinal direction of the second continuous sheet 30 or a slit of a predetermined length is provided for taking out the contents.

The inner bag 1 and the second contents 4 are sandwiched between the first and second continuous sheets 20 and 30 in a superimposed state.

The second content 4 is supplied onto the second continuous sheet 30, the inner bag 1 is placed on top of it with the opening/closing lid 5 facing upward, and the first continuous sheet 20 is placed on top of it. May be supplied. In this case as well, the opening/closing lid 5
The first continuous sheet 20 is placed so that the openings 21a are aligned with the openings 21a formed in the first continuous sheet 20.

Then, the heat sealer 203 seals both longitudinal edges of the first and second continuous sheets 20 and 30 to each other as heat seal portions 24 .

Next, the outer bag 2 is closed laterally using a lateral heat sealer 204 to form a heat seal portion 23.
form.

Note that after sealing in the lateral direction, both longitudinal edges may be heat-sealed.

The package is cut laterally at or near the heat-sealed portion 23 by the cutter 205 to obtain individual packages 7.

〔Effect of the invention〕

According to the manufacturing method of the present invention, a package containing a plurality or plurality of two types of articles, one of which requires sealing (for example, an article in a wet state) and the other does not require sealing. For products that require sealing, packaging that can be opened and sealed repeatedly can be used for pre-production management compared to the conventional manufacturing method disclosed in Japanese Patent Publication No. 58-41842. , conditions can be set very easily, manufacturing is simple, and continuous production can be easily realized.

That is, according to the manufacturing method of the present invention, the sheet is made of an airtight sheet and has an outlet for taking out the first content or a notch for forming the outlet, and a flexible sheet that covers the outlet or notch. First, the first contents are hermetically stored in an inner bag having an opening/closing lid, and then an opening for taking out the first contents or notches for forming the openings are made at predetermined intervals. In the formed continuous sheet, the surface opposite to the opening/closing lid of the inner bag contacts the second content, and the opening/closing lid of the inner bag matches the opening formed in the continuous sheet or the notch for forming the opening. In this way,
The inner bag and the second contents are supplied to the continuous sheet, and the inner bag and the second contents are wrapped with the continuous sheet in a state where they overlap directly, and the continuous sheet becomes the outer bag. .

As described above, according to the manufacturing method of the present invention, since the contents removal opening of the inner bag (where the opening/closing lid is located) is aligned with the opening of the outer bag, it is possible to repeatedly unseal items that require sealing. It is possible to produce a package that can be sealed. That is, in the package manufactured by the method of the present invention, the opening/closing lid of the inner bag can be opened and closed through the opening formed in the outer bag. Items requiring individual or multiple seals are removed through the openings of the outer bag and inner bag, and
It can be sealed by closing the opening/closing lid of the inner bag again.

Further, according to the manufacturing method of the present invention, the continuous sheet is provided with an outlet for taking out the second content or a cut for forming the outlet at a location parallel to the opening for taking out the first content. Set up or
The longitudinal edges of the continuous sheets may be simply overlapped with each other without being heat-sealed, or the second continuous sheet may be provided with an outlet for taking out the second content or a cut for forming an outlet. Since the second bag stored in the outer bag
The contents can be easily taken out. In other words, even for multiple items or multiple items stored in an outer bag that do not require airtightness, there is a take-out opening or heat-sealed opening for taking out the second contents without damaging the outer bag. You can take them out sequentially starting from the places where they are not.

According to the manufacturing method of the present invention, when packaging a first content that requires sealing (for example, a wet item) and a second content, the first content is After the first contents are hermetically stored in an inner bag having a take-out port for taking out the contents or a cut for forming the take-out port and a flexible opening/closing lid that covers the take-out port or the cut, Since the first content and the second content stored in this inner bag are packaged in a continuous sheet, even if the first content is wet, it will not be as normal after being stored in the inner bag. It can be handled in the same way as a dry product, so packaging processes such as feeding, transporting, wrapping, etc. are simple. In addition, since the inner bag and the second contents are directly stacked on top of each other, two types of items can be stored in three
Compared to the method of sandwiching between continuous sheets, supplying, transporting, and wrapping are easier.

According to the manufacturing method of the present invention, heat sealing when forming the outer bag is performed by simply overlapping both ends of a continuous sheet or by overlapping two sheets. It is easier to set conditions such as temperature and pressure during heat sealing, and to manage and adjust them, compared to the case where heat sealing is performed by overlapping them.

Furthermore, according to the method of the present invention, the first contents that require sealing (for example, wet items) are first hermetically stored in an inner bag made of an airtight sheet, so that the continuous sheet (outer bag) 1st during the packaging process by
The liquid impregnated with the contents will not ooze out into the surrounding area. Therefore, the second content will not be wetted by the impregnating liquid of the first content and the product value will not be lost, and the heat sealing part will not be wet, so the heat sealing when forming the outer bag will be easy. Easy to do.

Furthermore, according to the method for producing a package of the present invention, the inner bag sheet is relatively thick because airtightness is required, but the outer bag sheet can be relatively thin. Therefore, the cost of the sheet as a whole package is reduced. Moreover, even when heat-sealing the outer bag by overlapping it with the heat-sealed portion of the inner bag as shown in FIG. 14, heat is easily transferred, so heat sealing can be performed reliably.

As described above, according to the manufacturing method of the present invention, continuous production can be easily performed, and the cost of the sheet is low, so that an inexpensive product can be provided.
