Description

The present invention relates to a packaging bag and a packaging bag containing articles.

BACKGROUND ART Packaging bodies for packaging articles, such as flexible packaging containers containing internal liquids such as flexible materials, have been known. Examples of such packages include those described in Patent Document 1 and Patent Document 2.

The package described in Patent Document 1 is a paper packaging bag formed into a rectangular tube shape, and has window holes on most of the four side surfaces in the longitudinal direction. According to such a package, the articles contained in the package can be confirmed from the outside of the package, and after use, the articles can be recycled as used paper.

In the package described in Patent Document 2, a support piece for supporting stored articles is formed on the bottom of a packaging box made of paperboard. According to such a package, it is possible to prevent the stored article from moving with the support piece, so it is possible to prevent breakage and damage to the article, and after use, it is possible to prevent the housed article from moving. It is possible to recycle.

However, since the package described in Patent Document 1 is formed into a rectangular tube shape, when storing flat articles such as newspapers, the articles can be densely accumulated in the internal storage space. When accommodating articles of other shapes such as flexible packaging containers, wasteful empty space is created in the accommodating space, resulting in the problem that the articles cannot be accumulated efficiently. In such a case, the article becomes easy to move within the storage space, and there is a risk that the article will be damaged or damaged. Moreover, since the proportion of the storage space occupied by the stored items is small, when the packaging body is discarded, the amount of waste is inevitably increased, which results in a result that goes against the recent demands for reduction properties.

Moreover, since the package described in Patent Document 2 is configured to individually support the accommodated articles using the support pieces, wasteful empty space is likely to be created in the accommodation space. For this reason, although the package described in Patent Document 2 can prevent breakage and damage to the articles housed in the accommodation space, there is a problem that it lacks the ability to accumulate and reduce the articles.

As described above, the packages described in Patent Document 1 and Patent Document 2 cannot be said to have taken into account the ability to accumulate or reduce the ability of articles, and it can be said that there is still room for improvement.

The present invention relates to providing a packaging bag and an article-filled packaging bag that can overcome the drawbacks of the prior art described above.

The present invention relates to a packaging bag that is made of a sheet material including a paper base material and has a storage space that can accommodate flexible articles.
The packaging bag has a front part, a back part facing the front part, and a pair of side parts connecting both ends of the front part and the back part, respectively, with the article stored in the storage space. It is preferable that the body be configured to have a body portion, a bottom portion connected to a lower end portion of the body portion, and a top portion that opens or closes an upper end opening of the body portion.
It is preferable that a notch part is formed between at least one of the pair of side parts and the bottom part to expose a part of the article accommodated in the accommodation space.

The present invention relates to a packaging bag containing articles.
Preferably, the article-containing packaging bag includes the packaging bag and a plurality of the articles accommodated in a stacked state in the packaging bag.

According to the packaging bag of the present invention, although it has a simple configuration, it is possible to simultaneously satisfy all of the requirements of product accumulation stability, recyclability, and reduceability.

Hereinafter, the present invention will be described based on preferred embodiments thereof with reference to the drawings. FIG. 1 is a schematic front view of the packaging bag 1 of the present invention, and FIG. 2 is a schematic developed view of the packaging bag 1.
As shown in FIGS. 1 and 2, the packaging bag 1 is made of a sheet material S including a paper base material, and by storing the article G inside (hereinafter referred to as "accommodation space SS"), the packaging bag 1 has a bottom part 10. , a body portion 20 and a top surface portion 30 are formed. The bottom part 10, body part 20, and top part 30 formed in the packaging bag 1 will be described later. Note that the sheet material S containing the paper base material may be a sheet in which polymer base materials are laminated.

The sheet material S is, for example, a paper base such as kraft paper such as bleached kraft paper, single gloss bleached kraft paper, coated paper obtained by coating kraft paper with paint, base paper for foil, high quality paper, rayon paper, pure white roll paper, etc. Materials can be used.
Further, the sheet material S may be made of the above-mentioned paper base material subjected to crepe processing, etc., and may be made of polyester, polyamide, polypropylene, polyethylene, polycarbonate, polyacetal resin film, or cellulose. It is also possible to laminate based films. For example, polyester resin films include polyethylene terephthalate (PET), amorphous polyethylene terephthalate (amorphous PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), etc. As the polyamide resin film, stretched nylon (ONy), unstretched nylon (CNy), nylon 6, nylon 66, nylon 11, nylon 12, MXD6, etc. can be used. In addition, as the polypropylene resin film, polypropylene materials such as oriented polypropylene (OPP), unoriented polypropylene (CPP), isotactic PP, syndiotactic PP, atactic PP, random PP, and block PP are used. Examples of polyethylene resin films include high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ultra low density polyethylene (ULDPE), Ethylene-vinyl alcohol copolymer (EVOH) or the like can be used.
In this way, the sheet material S only needs to contain at least a paper base material, and includes not only a paper base material but also a wide range of materials such as those in which a resin film is laminated on the paper base material. Therefore, since the packaging bag 1 in this embodiment is formed of the sheet material S containing the paper base material, it can be reused as a raw material and has high recyclability, and the amount of resin material used It is also advantageous from the viewpoint of reduction, such as reduction of .
The content of cellulose fibers such as pulp fibers in the sheet material S is preferably 50% by mass or more, more preferably 70% by mass or more, and even more preferably 90% by mass or more.

The basis weight of the sheet material S is preferably 40 g/m ² or more from the viewpoint of ensuring the strength of the packaging bag 1 and minimizing the occurrence of wrinkles when the article G is stored in the storage space SS. . In this case, if the sheet material S has a basis weight of, for example, 100 g/m ² or more, a handle may be attached to the top surface 30 of the packaging bag 1.
Note that the basis weight of the sheet material S mentioned above is the sum of the basis weight of the paper base material and the basis weight of other members when other members such as resin films are laminated on the paper base material. It means. For example, when a resin film with a basis weight of 20 g/m ² is laminated on a paper base material with a basis weight of 20 g/m ² , the basis weight of the entire sheet material S is 40 g/m ² .

As shown in FIG. 2, the packaging bag 1 is made by using a rectangular sheet material S cut to a predetermined size, for example, a vertical width H of 400 mm and a horizontal width W of 730 mm. It has become.
Hereinafter, a procedure for creating a packaging bag 1 using such a sheet material S will be described with reference to FIG. 2.
In the following, for convenience of explanation, the upper side of the sheet material S shown in FIG. That's it. Further, the left-right direction in the following description means the left-right direction on the paper in FIG.

Creation of the packaging bag 1 begins with forming the notch 40 and the second notch 50 in a sheet S cut into a rectangular shape.
In this embodiment, each of the cut portions 40 and the second cut portions 50 is provided in pairs on the left and right, and is formed by cutting the sheet material S into a triangular shape.

The pair of notches 40, 40 are formed on the lower side Sb side of the sheet S at a predetermined interval in the left-right direction. For example, if the sheet material S has the aforementioned vertical width H of 400 mm and horizontal width W of 730 mm, the cut portion 40 has a base of 180 mm (“width W1” in FIG. 2) and a height of 120 mm (“width W1” in FIG. 2). It can be formed into an isosceles triangular shape with a "vertical width H1"). In this case, one notch 40 can be formed in the right direction starting from a position 95 mm (“width W2” in FIG. 2) away from the left side Sl, and the other notch 40 can be formed 95 mm (“width W2” in FIG. 2) from the right side Sr. It is possible to form it to the left with a starting point at a distant position ("width W3" in FIG. 2).

On the other hand, the pair of second notches 50, 50 are formed on the upper side Su of the sheet S at a predetermined interval in the left-right direction. For example, if the sheet material S has the above-mentioned vertical width H of 400 mm and width W of 730 mm, the second notch 50 has a base of 180 mm ("width W1" in FIG. 2) and a height of 140 mm ( It can be formed into an isosceles triangular shape with a "vertical width H2" of 2). In this case, the second notches 50, 50 can be formed at positions symmetrical to the notches 40, 40. That is, one second notch 50 can be formed in the right direction starting from a position 95 mm away from the left side Sl (the "width W2" in FIG. 2), and the other second notch 50 can be formed rightward from the right side Sr. It is possible to form it to the left starting from a position 95 mm away from (the "width W3" in FIG. 2).

In the example described above, the cut portion 40 and the second cut portion 50 are formed at positions that are approximately symmetrical to each other, but they may be formed at other positions. Further, in the above-mentioned example, the cut portion 40 and the second cut portion 50 are formed in the shape of an isosceles triangle, but other shapes such as an equilateral triangle, a triangle with different side lengths, a quadrilateral, etc. It can be formed into a polygonal, circular, oval, or other shape.

After forming the above-described notch 40 and second notch 50, the packaging bag 1 is made by (1) applying an adhesive material such as glue or tape with the right side Sr and left side Sl of the sheet material S overlapped with each other; (2) connecting the pair of lower end portions Sb1 and Sb2 that constitute the lower side Sb to each other using the above-mentioned adhesive member, so that the bag-like shape is formed. There is.
As mentioned above, if the size of the sheet material S is such that the vertical width H is 400 mm and the horizontal width W is 730 mm, the width of each bonded part Sp, Sp where the right side Sr and left side Sl are bonded together is, for example, 15 mm. can do.

In addition, after the packaging bag 1 is created according to the procedure described above, it can be folded at the positions of a pair of folding lines L and L shown in FIG. 2 to make it into a planar shape. In this way, when a plurality of packaging bags 1 are created, they can be stored compactly by stacking them.
In addition, in the above-mentioned example of creating the packaging bag 1, after forming the cut portion 40 and the second cut portion 50, the right side Sr, the left side Sl, and the lower end portions Se1 and Se2 were bonded together to form a bag shape. It is also possible to perform the reverse procedure, that is, to form the bag shape and then form the cut portion 40 and the second cut portion 50.

Here, an example of the article G accommodated in the packaging bag 1 will be described with reference to FIG. 3.
As shown in FIG. 3, the article G according to the present embodiment is a flexible packaging container in which a storage part capable of storing liquid content is formed by joining each part of a front sheet, a back sheet, and a bottom sheet. be.

Article G has a standing pouch shape in which a front sheet, a back sheet, and a bottom sheet are made of resin films, and a gusset is formed at the bottom. The article G configured in this manner is configured such that its outer shape is relatively easily deformed when an external force is applied. Note that the article G can contain, as internal liquids, for example, refillable liquids such as shampoo, rinse hair conditioner, liquid detergent, and fabric softener.

A shoulder portion Gs is formed at the upper end of the article G, and a spout forming portion Gs that forms a spout by cutting along a cutting line or the like is protruded from the shoulder portion Gs. Further, on the front sheet of the article G, display information GI consisting of characters such as "product name" that can identify the article G is printed. Note that the display information GI here refers to information that allows users to recognize product information such as the "product name" of the product G, and provider information such as the vendor and manufacturer of the product G. In addition to letters, the meaning broadly includes figures, symbols, or anything composed of a combination of these.

As shown in FIGS. 1 to 3, in this embodiment, three articles G are accommodated in the accommodation space SS in a state in which some of the articles G are overlapped with each other (the state shown in FIG. 3).
By accommodating the three articles G in this state in the storage space SS, the packaging bag 1 is transformed from a planar shape into a substantially rectangular parallelepiped shape in which a bottom section 10, a body section 20, and a top section 30 are formed. It has become so. In addition, in order to facilitate understanding of the present invention, the dashed-dotted line shown in FIG. 2 indicates the position of the bottom part 10 etc. that is formed when a plurality of articles G shown in FIG. 3 are stored in the storage space SS. The position of the container can be changed if it accommodates items of other shapes.

The bottom surface portion 10 has a depth that is substantially the same as the width in the depth direction of the bottom side of the three articles G in the state shown in FIG. 3, and is formed in a substantially rectangular shape. The body part 20 includes a front part 21 that is continuous to the front side in the depth direction of the bottom part 10 , a back part 22 that is continuous to the back side of the bottom part 10 in the depth direction and faces the front part 21 , and a front part 21 and It has a pair of side surfaces 23, 23 that connect both ends of the back surface section 22, respectively. The top surface section 30 extends from the upper end sides of the front surface section 21 and the back surface section 22, respectively, and opens or closes the upper end opening of the body section 20.

The cut portion 40 formed in the sheet material S (see FIG. 2) is arranged in an open state between the bottom surface portion 10 and the side surface portion 23. Therefore, in the present embodiment, the bottom side corner portions Gbe of each of the three articles G located on both sides are arranged to protrude from the pair of notches 40, respectively.

For example, in a packaging bag in which the notch 40 is not formed, wasteful empty space is likely to occur between the product G and the product G on both sides of the lower part of the storage space in the longitudinal direction. Both ends tend to be crushed, resulting in a poor appearance.
On the other hand, in the packaging bag 1 according to the present embodiment, since the notch 40 is formed between the bottom part 10 and the side part 23, such a situation does not occur.

Furthermore, in this embodiment, by causing a part of the article G to protrude from the notch 40, the article G can be held within the storage space SS and can be brought into close contact with the inner surface of the packaging bag 1. It is.
Therefore, in the present embodiment, even when a plurality of articles G are stored in the storage space SS in an overlapping state (the state shown in FIG. 3), the movement of the articles G is caused by (1) engagement with the notch 40, and (2) it is regulated by the frictional force generated between it and the inner surface of the packaging bag 1, so it is possible to maintain that state stably.
Therefore, according to the present embodiment, it is possible to not only make it difficult for the articles G to be damaged or damaged, but also to improve the ability to accumulate the articles G.

Further, in this embodiment, by forming the cut portion 40, it is possible to reduce the usage amount of the sheet S used in the packaging bag 1.
Therefore, according to the present embodiment, it is possible to reliably reduce the amount of waste when disposing of the packaging bag 1, so that it is possible to achieve a high reduction property. In addition to this, when the packaging body 1 is formed of, for example, a paper base material, it is possible to have excellent recyclability.

As described above, since the packaging bag 1 according to the present embodiment is formed of the sheet material S that includes at least a paper base material, it can be highly recyclable.

As described above, according to this embodiment, although it has a simple configuration, it is possible to simultaneously satisfy all of the accumulation stability, recyclability, and reduceability of the articles G.

Furthermore, in this embodiment, the article G is a flexible packaging container that deforms relatively easily when external force is applied.
That is, according to the present embodiment, when a plurality of articles G are stored in the storage space SS in a superimposed state (the state shown in FIG. 3), the articles G are partially deformed in the notch 40 and fit together. In addition, it is possible to bring the articles G into close contact with each other.
Therefore, in this embodiment, the movement of the articles G within the storage space SS can be further restricted by the frictional force generated between the articles G, so that the accumulation of the articles G can be further improved. be.

Further, in this embodiment, since the article G is a flexible packaging container with a gusset formed at the bottom, by fitting the gusset into the notch 40, this can be attached to the bottom 10 side of the packaging bag 1. It is possible to form a gusset similar to the above.
That is, in this embodiment, since the articles G placed on the bottom surface part 10 can be accommodated in an upright state, the articles G can be more stably accumulated.

In this embodiment, a soft packaging container is used as the article G to be stored in the storage space SS, but if the article is deformable when external force is applied, that is, the article is flexible, Other articles such as a relatively hard container such as a PET bottle capable of containing a liquid for use or an article made of an elastically deformable elastomer may also be used.

Further, in this embodiment, the article G having a standing pouch shape is used, but as long as the article can be made to protrude from the notch 40 when stored in the storage space SS, Since movement can be restricted, etc., other shapes may be used. In this respect, it can be said that the packaging bag 1 according to this embodiment has a high degree of freedom in the shape of the articles stored in the storage space S.

As shown in FIGS. 1 to 3 and FIG. 7(a), the packaging bag 1 according to the present embodiment has a circular shape in a predetermined area (hereinafter referred to as "area A") of the body 20, etc. A plurality of holes 60 are formed.
The plurality of holes 60 are for making display information GI printed on the outer surface of the article G visible from the outside of the packaging bag 1 when the article G is housed in the accommodation space SS.
Therefore, the area A is set at a position corresponding to the display information GI printed on the article G while the article G is accommodated in the accommodation space SS.
For example, if the article G is a flexible packaging container (see FIG. 3) and the size of the sheet material S is such that the vertical width H is 400 mm and the horizontal width W is 730 mm, the region A is The front part 21 of S can be set to have a vertical width of 80 mm and a horizontal width of 160 mm. In this case, area A starts at a position 285 mm away from the left side Sl (the length of "width W1" + "width width W2" in Fig. 2), moves 160 mm to the right, and moves 120 mm away from the bottom side Sb (in Fig. 2). It is possible to set a range of 80 mm upward using the length of the "vertical width H1" as a starting point.

From the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S, the diameter of the hole 60 is preferably 1 mm or more and 20 mm or less, and more preferably 4 mm or more and 10 mm or less. Note that the number and arrangement positions of the holes 60 in the region A can be determined as appropriate depending on the material used for the sheet material S, etc. Further, from the same viewpoint, the opening area ratio of the hole 60 in the area A is preferably 2% or more and 98% or less, more preferably 5% or more and 95% or less. With this configuration, for example, as shown in FIG. 8A, it is possible to reliably view the display information GI printed on the article G through the hole 60. In the example shown in FIG. 8A, for ease of understanding, the display information GI printed on the article G is set to "1", "2", and "3".

In this embodiment, the hole 60 is formed in a circular shape, but as shown in FIG. 7(b), it is possible to form it in the shape of a vertically long slit. In this case, the width of the slit-shaped hole 160 is preferably 1 mm or more and 10 mm or less, more preferably 2 mm or more and 4 mm or less, from the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S. The distance between each hole 160 is preferably 1 mm or more and 20 mm or less, more preferably 3 mm or more and 10 mm or less.

Further, the hole can be formed in a size that allows the user etc. to visually recognize the entire display information GI of "1", "2", and "3", as shown in FIG. 8(b), for example. (See “hole 260”).
Furthermore, the hole can also be formed in a shape corresponding to the display information GI. For example, as shown in FIG. 8(c), if the display information GI is the numbers "1", "2", and "3", the shape of the hole 360 is changed to a shape that imitates this, that is, the hole Each of the holes 361 to 363 can be formed in a shape that resembles the numbers "1" to "3". In this case, from the viewpoint of ensuring the strength of the sheet material S, it is also possible to configure it with a plurality of holes like the holes 362 and 363 shown in FIG. 8(c).

As shown in FIGS. 1 and 4 to 6, in this embodiment, after the article G is stored in the storage space SS, the upper end of the body 20 is The opening is closed.
As described above, since the pair of second notches 50, 50 are formed in the packaging bag 1, when the upper end opening of the body 20 is closed by the pair of top surfaces 30, 30, the article The spout forming part Gs and the upper side corner Gue of G are arranged so as to protrude from the second cut part 50.

That is, in this embodiment, since a part of the article G can be exposed on the top surface section 30 side of the packaging bag 1 as well as on the bottom surface section 10 side, there is no space between the article G and the article G in the storage space SS. It is possible to suppress the generation of wasteful empty space.
Therefore, in this embodiment, there is no possibility that wrinkles are formed on the top surface portion 30 side of the packaging bag 1 or the packaging bag 1 is crushed, resulting in poor appearance.

Furthermore, in the present embodiment, since the spout forming part Gs and the upper side corner part Gue of the article G can be fitted into the second notch 50, the movement of the article G within the storage space SS is further restricted. It is possible to do so. As a result, in this embodiment, the plurality of articles G can be more stably accumulated.

Furthermore, in this embodiment, by forming the second cut portion 50, it is possible to further reduce the usage amount of the sheet S used in the packaging bag 1.
Therefore, according to the present embodiment, it is possible to reliably reduce the amount of waste when discarding the packaging bag 1, so that it is possible to achieve a higher reduction property.

In this embodiment, two second notches 50 are provided, but depending on the shape of the article to be stored in the storage space S, one of them may be omitted, or the second notch 50 itself may be omitted. It is also possible to omit it.

The upper end opening of the body part 20 can be closed using a known method, for example, by folding the pair of top parts 30, 30 in an overlapping state, and then attaching this to the back part using an adhesive member 70 such as tape or glue. This can be done by attaching it to 22 (see FIG. 6).
At this time, in order to prevent unnecessary empty space from occurring between the upper side of the article G and the inner surface of the packaging bag 1, at a position close to the upper side of the article G or a position in contact with the upper side of the article G, Preferably, the upper end opening of the body 20 is closed. Thereby, the outer surface of the article G and the inner surface of the packaging bag 1 can be further brought into close contact with each other, so that the articles G can be stacked more stably.
At this time, the occupancy rate of the articles G in the storage space SS is preferably 70% or more from the viewpoint of ensuring the stability of the accumulation of the articles G.

In this embodiment, two notches 40 are formed on the bottom 10 side of the packaging bag 1, but one of them may be omitted.
Moreover, in this embodiment, although the hole 60 or the hole 160 is formed in the packaging bag 1, this can also be omitted.
Furthermore, in this embodiment, the bottom part 10 etc. are formed by storing the article G in the storage space SS, but for example, by separately placing cardboard or the like on the bottom part 10 side, the storage space It is also possible to form the bottom part 10 and the like before storing the article G in the space SS.
Further, in this embodiment, a pair of top surface portions 30, 30 are provided, but for example, it is also possible to omit the top surface portion 30 on the back surface portion 22 side.
