Description

【Technical Field】 【0001】 The present invention relates to a packaging bag and a packaging bag containing an article. 【Background Art】 【0002】 Conventionally, there has been known a package for packaging an article such as a flexible packaging container for containing an internal liquid such as a flexible material. Examples of such a package include those described in Patent Document 1 and Patent Document 2. 【0003】 The package described in Patent Document 1 is a paper packaging bag formed in a rectangular tube shape, having window holes in most of the longitudinal directions of four side surfaces. According to such a package, the article contained in the package can be confirmed from the outside of the package, and after use, it can be recycled as waste paper. 【0004】 The package described in Patent Document 2 is one in which a support piece for supporting the contained article is formed on the bottom surface portion of a cardboard box formed of cardboard. According to such a package, since the movement of the contained article can be prevented by the support piece, breakage and damage of the article can be prevented, and after use, it can be recycled in the same manner as Patent Document 1. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】 Japanese Patent Publication No. 58-034341 【Patent Document 2】 Registered Utility Model No. 3004416 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0006】 However, since the packaging described in Patent Document 1 is formed in a rectangular tube shape, when storing flat items such as newspapers, the items can be densely packed in the internal storage space. However, when storing items of other shapes, such as flexible packaging containers, there is wasted empty space in the storage space, resulting in the problem that items cannot be efficiently packed. In such cases, the items are more likely to move around within the storage space, which may cause damage or breakage. Moreover, because the proportion of the storage space occupied by the stored items is small, when the packaging is discarded, the amount of waste inevitably becomes large, which goes against the recent demand for reducerness. 【0007】 Furthermore, the packaging described in Patent Document 2 is configured to individually support the contained articles with support pieces, which tends to result in wasted empty space in the storage area. Therefore, although the packaging described in Patent Document 2 can prevent damage to the articles stored in the storage area, it has the problem of lacking in article stackability and reduceability. 【0008】 Thus, the packaging described in Patent Documents 1 and 2 cannot be said to take into consideration the collectibility and reduceability of the articles, and there is still room for improvement. 【0009】 The present invention relates to providing a packaging bag and a packaging bag containing articles that can overcome the drawbacks of the prior art described above. [Means for solving the problem] 【0010】 The present invention relates to a packaging bag made of a sheet material including a paper base material, which has a flexible storage space capable of accommodating articles. Preferably, the packaging bag is configured such that, when the article is contained in the storage space, it has a body portion having a front portion, a back portion opposite to the front portion, and a pair of side portions connecting the respective ends of the front portion and the back portion, a bottom portion connected to the lower end of the body portion, and a top portion that opens or closes the upper end opening of the body portion. Preferably, a notch is formed between at least one of the pair of side portions and the bottom portion, in which a part of the article housed in the storage space is exposed. 【0011】 This invention relates to a packaging bag for articles. Preferably, the packaging bag containing the articles comprises the packaging bag and a plurality of the articles contained within the packaging bag in a stacked state. [Effects of the Invention] 【0012】 The packaging bag of the present invention, despite its simple structure, can simultaneously satisfy all three requirements: stability of article storage, recyclability, and reduction. [Brief explanation of the drawing] 【0013】 [Figure 1] Figure 1 is a schematic front view showing an article contained in the packaging bag according to this embodiment.

[Modes for carrying out the invention] 【0014】 Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. FIG. 1 is a front schematic view of the packaging bag 1 of the present invention, and FIG. 2 is a developed schematic 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 accommodating an article G inside (hereinafter referred to as "accommodation space SS"), a bottom surface portion 10, a body portion 20, and a top surface portion 30 are formed. The bottom surface portion 10, the body portion 20, and the top surface portion 30 formed on the packaging bag 1 will be described later. Note that the sheet material S including the paper base material may be a sheet laminated with a polymer base material. 【0015】 For the sheet material S, for example, paper base materials such as sun-dried kraft paper, single-sided sun-dried kraft paper, etc., coated paper obtained by coating paint on kraft paper, base paper for foil, high-quality paper, rayon paper, pure white roll paper, etc. can be used. Further, the sheet material S may be the above-described paper base material subjected to creping or the like, and it is also possible to laminate a resin film such as a polyester-based, polyamide-based, polypropylene-based, polyethylene-based, polycarbonate-based, or polyacetal-based resin film or a cellulose-based film. For example, as the polyester-based resin film, polyethylene terephthalate (PET), amorphous polyethylene terephthalate (amorphous PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), or the like may be used. As the polyamide-based resin film, oriented nylon (ONy), non-oriented nylon (CNy), nylon 6, nylon 66, nylon 11, nylon 12, MXD6, or the like can be used. Further, as the polypropylene-based resin film, polypropylene-based materials such as oriented polypropylene (OPP), non-oriented polypropylene (CPP), isotactic PP, syndiotactic PP, atactic PP, random PP, block PP, or the like may be used. As the polyethylene-based resin film, 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. Thus, the sheet material S only needs to contain at least a paper base material, and widely includes not only the paper base material but also those in which a resin film is laminated on the paper base material. Therefore, since the packaging bag 1 in the present embodiment is formed of the sheet material S containing a paper base material, it can be made highly recyclable, such as being reused as a raw material, and is also advantageous from the viewpoint of reduction such as reducing the amount of resin material used. The content rate of cellulose-based 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 still more preferably 90% by mass or more. 【0016】 The basis weight of the sheet material S is preferably 40 g / m from the viewpoint of, for example, suppressing the occurrence of wrinkles as much as possible in a state where the article G is accommodated in the accommodation space SS while ensuring the strength of the packaging bag 1.2 That's all. In this case, the sheet material S has a basis weight of, for example, 100 g / m². 2 When using the above materials, a handle can also be attached to the top surface 30 of the packaging bag 1. Furthermore, the basis weight of the aforementioned sheet material S means that, when other materials such as resin films are laminated onto the paper base material, it is the sum of the basis weight of the paper base material and the basis weight of the other materials. For example, a basis weight of 20 g / m². 2 On a paper substrate, basis weight 20g / m² 2 When a resin film is laminated, the total basis weight of the sheet material S is 40 g / m². 2 This is the result. 【0017】 As shown in Figure 2, the packaging bag 1 is created 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. The following describes the procedure for creating a packaging bag 1 using such a sheet material S, with reference to Figure 2. For the sake of clarity, in the following explanation, the upper edge of the sheet material S shown in Figure 2 will be referred to as the upper edge Su, the lower edge as the lower edge Sb, the left edge as the left side Sl, and the right edge as the right side Sr. Furthermore, the left-right direction in the following explanation refers to the left-right direction on the paper in Figure 2. 【0018】 The creation of the packaging bag 1 begins with forming the cut portion 40 and the second cut portion 50 on the rectangularly cut sheet S. In this embodiment, both the cut portion 40 and the second cut portion 50 are provided in pairs on the left and right sides, and are formed by cutting the sheet material S into a triangular shape. 【0019】 The pair of notches 40, 40 are formed on the lower edge Sb side of the sheet S, with a predetermined gap between them in the left-right direction. For example, if the sheet material S has a vertical width H of 400 mm and a horizontal width W of 730 mm, the notches 40 can be formed in the shape of an isosceles triangle with a base of 180 mm ("W1" in Figure 2) and a height of 120 mm ("H1" in Figure 2). In this case, one of the notches 40 can be formed to the right, starting from a position 95 mm away from the left edge Sl ("W2" in Figure 2), and the other notch 40 can be formed to the left, starting from a position 95 mm away from the right edge Sr ("W3" in Figure 2). 【0020】 On the other hand, the pair of second notches 50, 50 are formed on the upper side Su of the sheet S, with a predetermined gap between them in the left-right direction. For example, if the sheet material S has a vertical width H of 400 mm and a horizontal width W of 730 mm, the second notches 50 can be formed in the shape of an isosceles triangle with a base of 180 mm ("W1" in Figure 2) and a height of 140 mm ("H2" in Figure 2). In this case, the second notches 50, 50 can be formed in positions symmetric to the notches 40, 40. That is, one of the second notches 50 can be formed to the right, starting from a position 95 mm away from the left side Sl ("W2" in Figure 2), and the other second notch 50 can be formed to the left, starting from a position 95 mm away from the right side Sr ("W3" in Figure 2). 【0021】 In the example described above, the notches 40 and 50 were formed in positions that are approximately symmetrical to each other, but it is also possible to form them in other positions. Furthermore, in the example described above, the notches 40 and 50 were formed in the shape of an isosceles triangle, but they can be formed in other shapes, such as an equilateral triangle, triangles with different side lengths, polygons other than triangles such as quadrilaterals, circles, ellipses, etc. 【0022】 The packaging bag 1 is formed into a bag shape by the following steps after the aforementioned cut portion 40 and second cut portion 50 are formed: (1) the right side Sr and left side Sl of the sheet material S are overlapped and bonded together using an adhesive material such as glue or tape, and (2) the pair of lower ends Sb1 and Sb2 that constitute the lower side Sb are connected to each other using the aforementioned adhesive material. As mentioned above, if the sheet material S has a vertical width H of 400 mm and a horizontal width W of 730 mm, the width of each bonding section Sp, Sp, where the right side Sr and the left side Sl are bonded together, can be set to, for example, 15 mm. 【0023】 Furthermore, after creating the packaging bag 1 using the procedure described above, it can be folded at the positions of the pair of fold lines L, L shown in Figure 2 to make it flat. In this way, if multiple packaging bags 1 are created, they can be stacked and stored compactly. In the example of creating the packaging bag 1 described above, the notches 40 and 50 were formed first, and then the right side Sr, the left side Sl, and the lower ends Se1 and Se2 were joined together to form a bag. However, it is also possible to perform the reverse procedure, that is, to form the bag first, and then form the notches 40 and 50. 【0024】 Here, an example of the article G contained in packaging bag 1 will be explained with reference to Figure 3. As shown in Figure 3, article G according to this embodiment is a flexible packaging container in which a storage compartment capable of containing liquid contents is formed by joining together the front sheet, back sheet, and bottom sheet. 【0025】 Item G has a standing pouch shape with a front sheet, back sheet, and bottom sheet made of resin film, and a gusset formed at the bottom. Item G, constructed in this way, is designed to deform relatively easily when external force is applied. Item G can contain liquids such as refillable shampoos, conditioners, liquid detergents, and fabric softeners. 【0026】 Shoulder portions Gs are formed at the upper end of item G, and spout-forming portions Gs are provided protruding from these shoulder portions Gs, which create a spout when cut along a cutting line or the like. In addition, display information GI consisting of characters such as the "product name" that can identify item G is printed on the front sheet of item G. Note that the display information GI referred to here is information that allows users to recognize product information such as the "product name" of item G, as well as provider information such as the seller or manufacturer of item G, and broadly includes not only characters but also figures, symbols, or combinations thereof. 【0027】 As shown in Figures 1 to 3, in this embodiment, the three articles G are arranged in the storage space SS with parts of them overlapping each other (as shown in Figure 3). The packaging bag 1 is designed to transform from a planar shape to a roughly rectangular parallelepiped shape, with a bottom portion 10, a body portion 20, and a top portion 30, by accommodating three articles G in this state within the storage space SS. The dashed line shown in Figure 2 indicates the position of the bottom portion 10, etc., formed when the multiple articles G shown in Figure 3 are accommodating the storage space SS, in order to facilitate understanding of the present invention. The position of the bottom portion 10, etc., may change when articles of other shapes are accommodating the bag. 【0028】 The bottom portion 10 has a depth that is approximately the same as the width in the depth direction of the bottom side of the three articles G in the state shown in Figure 3, and is formed in a substantially rectangular shape. The body portion 20 has a front portion 21 that is continuous with the front side of the bottom portion 10 in the depth direction, a rear portion 22 that is continuous with the rear side of the bottom portion 10 in the depth direction and faces the front portion 21, and a pair of side portions 23, 23 that connect the respective ends of the front portion 21 and the rear portion 22. The top portion 30 extends from the upper end sides of the front portion 21 and the rear portion 22, respectively, and opens or closes the upper end opening of the body portion 20. 【0029】 The notches 40 formed in the sheet material S (see Figure 2) are positioned with an opening between the bottom surface 10 and the side surface 23. Therefore, in this embodiment, the bottom corners Gbe of each of the three articles G located on both sides are positioned to protrude from the pair of notches 40. 【0030】 For example, in packaging bags where the notches 40 are not formed, unnecessary empty space tends to form between the item G and the bag on both longitudinal sides of the lower part of the storage space, which can lead to wrinkles forming or the longitudinal ends of the bottom surface being crushed, resulting in an unsightly appearance. In contrast, in the packaging bag 1 according to this embodiment, a notch 40 is formed between the bottom portion 10 and the side portion 23, so such a situation does not occur. 【0031】 Furthermore, in this embodiment, by allowing a portion 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. Therefore, in this embodiment, even when multiple articles G are stored in the storage space SS stacked on top of each other (as shown in Figure 3), the movement of the articles G is restricted by (1) engagement with the notch 40 and (2) frictional force generated between the articles and the inner surface of the packaging bag 1, making it possible to maintain that state stably. Therefore, according to this embodiment, not only is it less likely for damage or breakage to occur to the item G, but the stackability of the item G can also be improved. 【0032】 Furthermore, in this embodiment, by forming the notched portion 40, it is possible to reduce the amount of sheet S used in the packaging bag 1. Therefore, according to this embodiment, it is possible to reliably reduce the amount of waste generated when disposing of the packaging bag 1, thus making it highly recyclable. In addition, if the packaging body 1 is formed from, for example, a paper base material, it is possible to make it highly recyclable. 【0033】 As described above, since the packaging bag 1 according to this embodiment is formed from a sheet material S that includes at least a paper base material, it can be made highly recyclable. 【0034】 As described above, this embodiment allows for a simple configuration while simultaneously satisfying all three requirements for the accumulation stability, recyclability, and reduceability of the article G. 【0035】 Furthermore, in this embodiment, article G is a flexible packaging container that deforms relatively easily when an external force is applied. In other words, according to this embodiment, when multiple articles G are stored in the storage space SS in a stacked state (as shown in Figure 3), a portion of the articles G can be fitted into the notch 40 in a deformed state, and the articles G can be brought 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 frictional forces generated between the articles G, thereby improving the stackability of the articles G. 【0036】 Furthermore, in this embodiment, since the item G is a flexible packaging container with a gusset formed at the bottom, it is possible to form a similar gusset on the bottom surface 10 side of the packaging bag 1 by fitting the gusset into the notch 40. In other words, in this embodiment, since the articles G placed on the bottom surface 10 can be stored in an upright position, the articles G can be accumulated more stably. 【0037】 In this embodiment, a flexible packaging container was used as the article G contained in the containment space SS. However, other articles that can be deformed when an external force is applied, i.e., articles that are flexible, may also be used, such as relatively rigid containers like PET bottles that can contain the liquid inside, or articles made of elastically deformable elastomer. 【0038】 Furthermore, although this embodiment uses an article G having a standing pouch shape, any article that can protrude from the notch 40 when stored in the storage space SS may be used, as it is possible to restrict the movement of the article within the storage space SS. In this respect, the packaging bag 1 according to this embodiment offers a high degree of freedom in the shape of the article stored in the storage space S. 【0039】 As shown in Figures 1 to 3 and Figure 7(a), the packaging bag 1 according to this embodiment has multiple circular holes 60 formed in a predetermined area (hereinafter referred to as "area A") such as the body portion 20. The multiple holes 60 are designed to allow the display information GI printed on the outer surface of the article G to be visible from outside the packaging bag 1 when the article G is contained in the storage space SS. Therefore, when the item G is contained in the storage space SS, area A is set to a position corresponding to the display information GI printed on the item G. For example, if item G is a flexible packaging container (see Figure 3), and the sheet material S has the aforementioned dimensions of vertical width H of 400 mm and horizontal width W of 730 mm, then area A can be set to a size of vertical width 80 mm and horizontal width 160 mm on the front part 21 of the sheet material S. In this case, area A can be set to a range of 160 mm to the right, starting from a position 285 mm away from the left edge Sl (the length of "horizontal width W1" + "horizontal width W2" in Figure 2), and 80 mm upward, starting from a position 120 mm away from the bottom edge Sb (the length of "vertical width H1" in Figure 2). 【0040】 The diameter of the holes 60 is preferably 1 mm to 20 mm, and more preferably 4 mm to 10 mm, from the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S. The number and position of the holes 60 in region A can be appropriately determined according to the material used for the sheet material S. Similarly, from the same viewpoint, the opening area ratio of the holes 60 in region A is preferably 2% to 98%, and more preferably 5% to 95%. With this configuration, for example, as shown in Figure 8(a), it is possible to reliably see the display information GI printed on the article G through the holes 60. In the example shown in Figure 8(a), the display information GI printed on the article G is labeled "1", "2", and "3" for ease of understanding. 【0041】 In this embodiment, the holes 60 are formed in a circular shape, but as shown in Figure 7(b), they can be formed in a vertically elongated slit shape. In this case, the width of the slit-shaped holes 160 is preferably 1 mm to 10 mm, more preferably 2 mm to 4 mm, from the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S, and the spacing between each hole 160 is preferably 1 mm to 20 mm, more preferably 3 mm to 10 mm. 【0042】 Furthermore, the holes can be formed to a size that allows the entire GI display information "1", "2", and "3" to be visible to the user, as shown in Figure 8(b) (see "Hole 260"). Furthermore, the holes can also be formed in a shape corresponding to the display information GI. For example, as shown in Figure 8(c), if the display information GI is the numbers "1", "2", and "3", the shape of hole 360 ​​can be made to mimic these numbers, that is, holes 361 to 363 can each be made to mimic 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 construct it with multiple holes, as shown in holes 362 and 363 in Figure 8(c). 【0043】 As shown in Figures 1 and 4 to 6, in this embodiment, after the article G is placed in the storage space SS, the upper end opening of the body 20 is closed by connecting the pair of top surfaces 30, 30 together. As described above, since the packaging bag 1 has a pair of second notches 50, 50 formed therein, when the upper end opening of the body portion 20 is closed by the pair of top portions 30, 30, the spout forming portion Gs and the upper side corner portion Gue of the article G are positioned to protrude from the second notches 50. 【0044】 In other words, in this embodiment, just as with the bottom portion 10, a portion of the article G can be exposed on the top portion 30 of the packaging bag 1, making it possible to suppress the occurrence of unnecessary empty space between the article G and the storage space SS. Therefore, in this embodiment, wrinkles or crushing of the top surface 30 of the packaging bag 1 will not occur, which would result in an unsightly appearance. 【0045】 Furthermore, in this embodiment, the spout-forming portion Gs and the upper side corner portion Gue of the article G can be fitted into the second notch portion 50, making it possible to further restrict the movement of the article G within the storage space SS. As a result, in this embodiment, multiple articles G can be stacked more stably. 【0046】 Furthermore, in this embodiment, by forming the second notch 50, it is possible to further reduce the amount of sheet S used in the packaging bag 1. Therefore, according to this embodiment, it is possible to reliably reduce the amount of waste generated when disposing of the packaging bag 1, thus making it more reduceable. 【0047】 In this embodiment, two second notches 50 are provided, but depending on the shape of the items to be stored in the storage space S, one of them may be omitted, or the second notches 50 themselves may be omitted. 【0048】 The upper end opening of the body portion 20 can be closed by a known method, for example, by folding the pair of top portions 30, 30 together and then attaching them to the back portion 22 using an adhesive member 70 such as tape or glue (see Figure 6). In this case, in order to prevent unnecessary empty space from being created between the upper side of the item G and the inner surface of the packaging bag 1, it is preferable to close the upper end opening of the body portion 20 at a position close to the upper side of the item G or at a position in contact with the upper side of the item G. This makes it possible to further tighten the contact between the outer surface of the item G and the inner surface of the packaging bag 1, thereby enabling more stable stacking of the item G. In this case, the occupancy rate of the storage space SS by the item G is preferably 70% or more, from the viewpoint of ensuring the stability of the accumulation of the item G. 【0049】 In this embodiment, two notches 40 are formed on the bottom surface 10 of the packaging bag 1, but it is possible to omit one of them. Furthermore, although a hole 60 or a hole 160 is formed in the packaging bag 1 in this embodiment, this can be omitted. Furthermore, in this embodiment, the bottom portion 10 etc. is formed by accommodating the article G in the storage space SS. However, it is also possible to form the bottom portion 10 etc. before accommodating the article G in the storage space SS by separately arranging, for example, cardboard or the like on the bottom portion 10 side. Furthermore, although a pair of top surfaces 30, 30 are provided in this embodiment, it is also possible to omit, for example, the top surface 30 on the rear surface 22 side. 【0050】 Although the present invention has been described above based on preferred embodiments and modifications thereof, the present invention is not limited to the embodiments and modifications described above. 【0051】 With regard to the embodiments described above, the present invention further discloses the following apparatus and method. <1> A packaging bag made of a sheet material containing at least a paper base material, having a flexible storage space capable of accommodating an article, With the article contained in the aforementioned storage space, the device is configured to have a body portion having a front portion, a rear portion facing the front portion, and a pair of side portions connecting the respective ends of the front portion and the rear portion, a bottom portion connected to the lower end of the body portion, and a top portion that opens or closes the upper end opening of the body portion.
