Abstract
Description
[Technical Field]
[0001] The present invention relates to a packaging bag and a packaging bag containing an item. [Background technology]
[0002] Conventionally, there have been known packages for packaging articles such as soft packaging containers for storing oral liquids such as fabric softeners. Examples of such packages include those described in Patent Documents 1 and 2.
[0003] The packaging described in Patent Document 1 is a paper packaging bag formed into a rectangular tube shape, with window holes along most of the length of each of the four sides. With this type of packaging, the items contained in the packaging can be confirmed from the outside of the packaging, and after use, the packaging can be recycled as waste paper.
[0004] The packaging described in Patent Document 2 is a packaging box made of paperboard, with support pieces formed on the bottom surface thereof to support the contained articles. With such a packaging, the support pieces can prevent the contained articles from shifting, thereby preventing breakage or damage to the articles, and after use, the packaging can be recycled in the same way as Patent Document 1. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Special Publication No. 58-034341 [Patent Document 2] Registered Utility Model No. 3004416 Summary of the Invention [Problem to be solved by the invention]
[0006] However, because the packaging body described in Patent Document 1 is formed in a rectangular tube shape, when flat items such as newspapers are stored, the items can be densely packed in the internal storage space. However, when other shaped items such as flexible packaging containers are stored, wasted empty space is generated in the storage space, resulting in the problem that the items cannot be efficiently packed. In such cases, the items tend to move around within the storage space, which can lead to the risk of breakage or damage to the items. Moreover, because the proportion of the stored items in the storage space is small, when the packaging body is discarded, the amount of waste is inevitably large, which goes against the recent demand for reduction.
[0007] Furthermore, the packaging body described in Patent Document 2 is configured to support the stored articles individually with support pieces, which tends to result in wasted empty space in the storage space. Therefore, although the packaging body described in Patent Document 2 can prevent breakage or damage to the articles stored in the storage space, it has the problem of lacking in the ability to collect and reduce articles.
[0008] As described above, it is difficult to say that the packages described in Patent Documents 1 and 2 take into consideration the storability and reducibility of articles, and there is still room for improvement.
[0009] The present invention relates to providing a packaging bag and a packaging bag containing an article that can eliminate 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, and having a storage space formed therein capable of storing flexible items. It is preferable that the packaging bag is configured so that, when the item is stored in the storage space, it has a body portion having a front portion, a back portion facing the front portion, and a pair of side portions connecting both end portions 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. It is preferable that a notch be formed between at least one of the pair of side surfaces and the bottom surface, through which a part of the item stored in the storage space is exposed.
[0011] The present invention relates to a packaging bag containing an item. The packaging bag containing the articles preferably includes the packaging bag and a plurality of the articles contained in the packaging bag in a stacked state. [Effects of the Invention]
[0012] The packaging bag of the present invention has a simple structure, yet can simultaneously satisfy all of the requirements for stable accumulation of articles, recyclability, and reduction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0014] The present invention will now be described based on preferred embodiments with reference to the drawings. Fig. 1 is a schematic front view of a packaging bag 1 of the present invention, and Fig. 2 is a schematic development view of the packaging bag 1. 1 and 2, the packaging bag 1 is made of a sheet material S including a paper base material, and by storing an item G inside (hereinafter referred to as "storage space SS"), a bottom surface portion 10, a body portion 20, and a top surface portion 30 are formed. The bottom surface portion 10, body portion 20, and top surface portion 30 formed in the packaging bag 1 will be described later. The sheet material S including a paper base material may be a sheet laminated with a polymer base material.
[0015] The sheet material S can be, for example, a paper substrate such as bleached kraft paper, one-side gloss bleached kraft paper, coated paper made by coating kraft paper, foil base paper, fine paper, rayon paper, or pure white roll paper. The sheet material S may be the above-mentioned paper substrate subjected to creping or the like, or may be laminated with a polyester-based, polyamide-based, polypropylene-based, polyethylene-based, polycarbonate-based, or polyacetal-based resin film, or a cellulose-based film. For example, polyester-based resin films may include polyethylene terephthalate (PET), amorphous polyethylene terephthalate (amorphous PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), and polybutylene naphthalate (PBN), while polyamide-based resin films may include oriented nylon (ONy), unoriented nylon (CNy), nylon 6, nylon 66, nylon 11, nylon 12, and MXD6. In addition, polypropylene-based resin films may include polypropylene-based materials such as oriented polypropylene (OPP), unoriented polypropylene (CPP), isotactic PP, syndiotactic PP, atactic PP, random PP, and block PP, and polyethylene-based resin films may include high-density polyethylene (HDPE), medium-density polyethylene (MDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), ultra-low-density polyethylene (ULDPE), and ethylene-vinyl alcohol copolymer (EVOH). As described above, the sheet material S is sufficient as long as it contains at least a paper base material, and broadly includes not only paper base materials but also those in which a resin film is laminated onto the paper base material, etc. Therefore, since the packaging bag 1 in this embodiment is formed from the sheet material S containing a paper base material, it can be highly recyclable, for example, by 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 sheet material S preferably has a cellulosic fiber content of pulp fiber or the like of 50% by mass or more, more preferably 70% by mass or more, and even 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 minimizing the occurrence of wrinkles when the article G is accommodated in the accommodation space SS while ensuring the strength of the packaging bag 1.2 In this case, the sheet material S has a basis weight of, for example, 100 g / m 2 When the above-mentioned items are used, a handle can be attached to the top surface 30 of the packaging bag 1 or the like. In addition, when other materials such as resin films are laminated on the paper base material, the basis weight of the sheet material S mentioned above means the total value of the basis weight of the paper base material and the basis weight of the other materials. For example, when the basis weight is 20 g / m 2 paper base material, grammage 20g / m 2 When the resin film is laminated, the basis weight of the entire sheet material S is 40 g / m 2 This becomes:
[0017] As shown in Figure 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. Hereinafter, a procedure for producing a packaging bag 1 using such a sheet material S will be described with reference to FIG. In the following, for convenience of explanation, the upper side of the sheet material S shown in Figure 2 will be referred to as the upper side Su, the lower side of the sheet Sb, the left side of the sheet Sl, and the right side of the sheet Sr. Furthermore, the left-right direction in the following explanation refers to the left-right direction on the sheet in Figure 2.
[0018] The production of the packaging bag 1 begins with the step of forming the cut portion 40 and the second cut portion 50 in the sheet S that has been cut into a rectangular shape. In this embodiment, the cut portion 40 and the second cut portion 50 are each 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 cutouts 40, 40 are formed at a predetermined distance in the left-right direction on the lower side Sb of the sheet S. For example, if the sheet material S has the aforementioned vertical width H of 400 mm and horizontal width W of 730 mm, the cutout 40 can be formed in the shape of an isosceles triangle with a base of 180 mm ("horizontal width W1" in FIG. 2) and a height of 120 mm ("vertical width H1" in FIG. 2). In this case, one cutout 40 can be formed to the right, starting from a position 95 mm ("horizontal width W2" in FIG. 2) away from the left side Sl, and the other cutout 40 can be formed to the left, starting from a position 95 mm ("horizontal width W3" in FIG. 2) away from the right side Sr.
[0020] On the other hand, the pair of second cutouts 50, 50 are formed on the upper side Su of the sheet S at a predetermined distance 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 second cutouts 50 can be formed in the shape of an isosceles triangle with a base of 180 mm ("horizontal width W1" in FIG. 2) and a height of 140 mm ("vertical width H2" in FIG. 2). In this case, the second cutouts 50, 50 can be formed in positions that are line-symmetrical to the cutouts 40, 40. That is, one second cutout 50 can be formed rightward from a position 95 mm ("horizontal width W2" in FIG. 2) away from the left side Sl as its starting point, and the other second cutout 50 can be formed leftward from a position 95 mm ("horizontal width W3" in FIG. 2) away from the right side Sr as its starting point.
[0021] In the above example, the notch 40 and the second notch 50 are formed at positions that are approximately symmetrical to each other, but they can also be formed at other positions. Also, in the above example, the notch 40 and the second notch 50 are formed in the shape of an isosceles triangle, but they can be formed in other shapes, such as an equilateral triangle, a triangle with different side lengths, a polygon other than a triangle such as a rectangle, a circle, an ellipse, etc.
[0022] After forming the aforementioned cutout portion 40 and second cutout portion 50, the packaging bag 1 is formed into a bag shape by performing the following operations: (1) overlapping the right side Sr and left side Sl of the sheet material S with each other and bonding them together using an adhesive member such as glue or tape; and (2) connecting the pair of lower end portions Sb1, Sb2 that make up the lower side Sb with each other using the aforementioned adhesive member. As mentioned above, if the size of the sheet material S is a vertical width H of 400 mm and a horizontal width W of 730 mm, the horizontal width of each bonding portion Sp, Sp where the right side Sr and the left side Sl are bonded together can be, for example, 15 mm.
[0023] After the packaging bag 1 is produced according to the procedure described above, it can be folded at the position of a pair of fold lines L, L shown in Fig. 2 to form a flat shape. In this way, when a plurality of packaging bags 1 are produced, they can be stacked and stored compactly. In the example of manufacturing the packaging bag 1 described above, after forming the cutout portion 40 and the second cutout portion 50, the right side Sr, the left side Sl, and the lower end portions Se1 and Se2 are bonded together to form a bag shape, but it is also possible to use the reverse procedure, i.e., to form the cutout portion 40 and the second cutout portion 50 after forming the bag shape.
[0024] Here, an example of the article G contained in the packaging bag 1 will be described with reference to FIG. As shown in FIG. 3, the article G according to this embodiment is a flexible packaging container in which a storage space capable of storing a liquid content is formed by joining together the front sheet, the back sheet, and the bottom sheet.
[0025] The front, back, and bottom sheets of the product G are made of resin film, and the product G has a standing pouch shape with a gusseted bottom. The product G configured in this way is designed to deform relatively easily when subjected to an external force. The product G can also contain liquids for internal use, such as refills for shampoo, rinse hair conditioner, liquid detergent, fabric softener, etc.
[0026] A shoulder Gs is formed at the top end of the article G, and a spout forming portion Gs is protruded from the shoulder Gs to form a spout by cutting along a cutting line or the like. In addition, display information GI consisting of characters such as the "product name" that can identify the article G is printed on the front sheet of the article G. Note that the display information GI here refers to information that enables users to recognize product information such as the "product name" of the article G and provider information such as the seller or manufacturer of the article G, and is intended to broadly include not only characters but also figures, symbols, or combinations of these.
[0027] As shown in FIGS. 1 to 3, in this embodiment, three articles G are stored in the storage space SS in a state where they are partially overlapped with each other (the state shown in FIG. 3). By storing three articles G in the storage space SS in this state, the packaging bag 1 is deformed from a flat shape into a substantially rectangular parallelepiped shape having a bottom surface 10, a body portion 20, and a top surface 30. Note that, for ease of understanding the present invention, the dashed dotted lines shown in Fig. 2 indicate the positions of the bottom surface 10 and the like that are formed when multiple articles G shown in Fig. 3 are stored in the storage space SS, and when articles of other shapes, etc. are stored, the positions can be changed.
[0028] The bottom portion 10 is formed in a substantially rectangular shape, with a depth that is substantially the same as the width in the depth direction of the bottom sides of the three articles G in the state shown in Fig. 3. 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 back portion 22 that is continuous with the back 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 respectively connect both end portions of the front portion 21 and the back portion 22. The top portion 30 extends from the upper end sides of the front portion 21 and the back portion 22, respectively, and opens or closes the upper end opening of the body portion 20.
[0029] The cutouts 40 formed in the sheet material S (see FIG. 2) are arranged in an open state between the bottom surface portion 10 and the side surface portion 23. Therefore, in this embodiment, the bottom corners Gbe of each of the three articles G located on both sides are arranged to protrude from the pair of cutouts 40.
[0030] For example, in a packaging bag in which the cutout 40 is not formed, unnecessary empty space tends to be created between the item G and the bag on both sides of the longitudinal direction at the bottom of the storage space, which can result in wrinkles being formed or the longitudinal ends of the bottom surface being crushed, resulting in a poor appearance. In contrast, in the packaging bag 1 according to this embodiment, the cut portion 40 is formed between the bottom surface portion 10 and the side surface portion 23, so this situation does not occur.
[0031] In addition, in this embodiment, by having a portion of the item G protrude from the cut portion 40, the item G can be held within the storage space SS and can be made to adhere to the inner surface of the packaging bag 1. Therefore, in this embodiment, even when multiple items G are stored in a stacked state in the storage space SS (as shown in Figure 3), the movement of the items G is restricted by (1) the engagement with the cut portion 40 and (2) the frictional force generated between the items G and the inner surface of the packaging bag 1, so that state can be maintained stably. Therefore, according to this embodiment, not only is it difficult for the articles G to be broken or damaged, but it is also possible to improve the collectability of the articles G.
[0032] Furthermore, in this embodiment, by forming the cut portions 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 discarding the packaging bag 1, and thus the packaging bag 1 can be highly recyclable. In addition, if the packaging body 1 is made of, for example, a paper base material, the packaging body 1 can be highly recyclable.
[0033] As described above, the packaging bag 1 according to this embodiment is formed from the sheet material S that contains at least a paper base material, and therefore can be made highly recyclable.
[0034] As described above, according to this embodiment, even with a simple configuration, it is possible to simultaneously satisfy all of the requirements for stacking stability, recyclability, and reduction of the items G.
[0035] Furthermore, in this embodiment, the article G is a flexible packaging container that is relatively easily deformed when an external force is applied. In other words, according to this embodiment, when multiple items G are stored in a stacked state in the storage space SS (as shown in Figure 3), the items G can be fitted together in a state in which a portion of the items G is deformed in the cut portion 40, and the items G can be brought into close contact with each other. Therefore, in this embodiment, the movement of the items G within the storage space SS can be further restricted by frictional forces, etc., generated between the items G, thereby further improving the accumulation of the items G.
[0036] Furthermore, in this embodiment, since the item G is a soft packaging container with a gusset portion formed at the bottom, by fitting the gusset portion into the cut portion 40, it is possible to form a similar gusset portion on the bottom surface portion 10 side of the packaging bag 1. That is, in this embodiment, the articles G placed on the bottom surface portion 10 can be stored in an upright state, and therefore the articles G can be stacked more stably.
[0037] In this embodiment, a soft packaging container is used as the item G to be stored in the storage space SS, but other items may also be used as long as they are deformable when an external force is applied, i.e., flexible, such as a relatively hard container such as a PET bottle that can store oral liquid, or an item made of an elastically deformable elastomer.
[0038] Furthermore, in this embodiment, the article G has a standing pouch shape, but any other shape may be used as long as the article can be made to protrude from the cutout 40 when stored in the storage space SS, and movement of the article within the storage space SS can be restricted, etc. In this regard, the packaging bag 1 according to this embodiment can be said to have a high degree of freedom in the shape of the article to be stored in the storage space S.
[0039] As shown in Figures 1 to 3 and Figure 7(a), the packaging bag 1 of 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 plurality of holes 60 are intended to allow the display information GI printed on the outer surface of the item G to be visible from outside the packaging bag 1 when the item G is stored in the storage space SS. Therefore, the area A is set at a position corresponding to the display information GI printed on the item G when the item G is stored in the storage space SS. For example, if the item G is a flexible packaging container (see FIG. 3) and the sheet material S has the aforementioned vertical width H of 400 mm and horizontal width W of 730 mm, then the area A can be set to a vertical width of 80 mm and horizontal width of 160 mm on the front surface 21 of the sheet material S. In this case, the area A can be set to a range of 160 mm to the right from a position 285 mm away from the left side S1 (the length of "horizontal width W1" + "horizontal width W2" in FIG. 2) as the starting point, and 80 mm upward from a position 120 mm away from the bottom side Sb (the length of "vertical width H1" in FIG. 2).
[0040] The diameter of the hole 60 is preferably 1 mm or more and 20 mm or less, more preferably 4 mm or more and 10 mm or less, from the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S. The number and arrangement of the hole 60 in the region A can be determined appropriately depending on the material used for the sheet material S. From the same viewpoint, the opening area ratio of the hole 60 in the region 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. 8(a), the display information GI printed on the article G can be reliably viewed through the hole 60. In the example shown in FIG. 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 hole portions 60 are formed in a circular shape, but as shown in Fig. 7(b), they can also be formed in a vertically elongated slit shape. In this case, from the viewpoint of ensuring the visibility of the display information GI and the strength of the sheet material S, the width of the slit-shaped hole portions 160 is preferably 1 mm to 10 mm, more preferably 2 mm to 4 mm, and the interval between each hole portion 160 is preferably 1 mm to 20 mm, more preferably 3 mm to 10 mm.
[0042] In addition, the hole portion can be formed to a size that allows the user to see the entire display information GI of "1," "2," and "3," as shown in Figure 8(b) (see "hole portion 260"). Furthermore, the holes can 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 can be formed in a shape that imitates this, that is, the hole 361 to the hole 363 can be formed in a shape that imitates the numbers "1" to "3," respectively. In this case, from the viewpoint of ensuring the strength of the sheet material S, it is also possible to form the sheet material S with a plurality of holes, as in the hole 362 and the hole 363 shown in Fig. 8(c).
[0043] As shown in Figures 1 and 4 to 6, in this embodiment, after an item G is stored in the storage space SS, the upper end opening of the body portion 20 is closed by connecting the pair of top surface portions 30, 30 together, etc. As mentioned above, a pair of second cutouts 50, 50 are formed in the packaging bag 1, so that when the upper end opening of the body portion 20 is blocked by the pair of top surface portions 30, 30, the spout forming portion Gs and upper side corner portion Gue of the item G are positioned so as to protrude from the second cutouts 50.
[0044] In other words, in this embodiment, a portion of the item G can be exposed on the top surface 30 side of the packaging bag 1, just like on the bottom surface 10 side, so it is possible to prevent unnecessary empty space from being created between the item G and the storage space SS. Therefore, in this embodiment, the top surface 30 side of the packaging bag 1 does not become wrinkled or crushed, which would make the external appearance look bad.
[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 cutout portion 50, which further restricts movement of the article G within the storage space SS. As a result, in this embodiment, multiple articles G can be more stably stacked.
[0046] Furthermore, in this embodiment, by forming the second cut portions 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 packaging bag 1 that is discarded, thereby achieving a higher level of reduction.
[0047] In this embodiment, two second cutouts 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, and it is also possible to omit the second cutout 50 itself.
[0048] The upper opening of the body portion 20 can be closed using a known method, for example, by folding the pair of top surface portions 30, 30 together and then attaching them to the back surface portion 22 using an adhesive member 70 such as tape or glue (see Figure 6). At this time, in order to prevent any unnecessary empty space from being generated between the upper side of the article 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 article G or at a position that contacts the upper side of the article G. This allows the outer surface of the article G to be more closely attached to the inner surface of the packaging bag 1, making it possible to stack the article G more stably. In this case, the occupancy rate of the articles G in the storage space SS is preferably 70% or more from the viewpoint of ensuring stable accumulation of the articles G.
[0049] In this embodiment, two cutouts 40 are formed on the bottom surface 10 side of the packaging bag 1, but it is possible to omit one of them. In addition, in this embodiment, the hole 60 or the hole 160 is formed in the packaging bag 1, but this may be omitted. Furthermore, in this embodiment, the bottom surface portion 10, etc. is formed by storing the item G in the storage space SS, but it is also possible to form the bottom surface portion 10, etc. before storing the item G in the storage space SS, for example, by separately placing cardboard or the like on the bottom surface portion 10 side. Furthermore, 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 rear surface portion 22 side.
[0050] The present invention has been described above based on the preferred embodiments and modifications thereof, but the present invention is not limited to the above-described embodiments and modifications.
