Description

The present invention relates to a packaging bag.

Items such as sanitary paper are distributed in a film-like packaging bag, either as is or as individual packages, with multiple items stored in it. Conventional packaging bags have a main body in which the packaged items are stored, and a handle that is integrally provided on the top surface of the main body. A purchaser of the item can carry the item stored in the packaging bag by grasping the handle of such a packaging bag (see, for example, Patent Document 1).

Patent No. 4856412

However, after opening the packaging bag, dust and dirt (hereinafter sometimes referred to as dust) can easily enter from the outside, making it impossible to store unused items hygienically. Furthermore, after opening the packaging bag, items contained in the packaging bag may crumble inside the packaging bag or fly out of the packaging bag during storage, making it impossible to store the items stably.

The objective of the present invention is to provide a packaging bag that has excellent storage properties after opening.

The first aspect of the present invention is a packaging bag having a main body portion in which a packaged item is contained, a handle portion formed on the top surface of the main body portion, and an adhesive portion extending from the handle portion. In this specification, the packaged item refers to an article such as sanitary paper that is contained in the packaging bag. The main body portion is the main body of the packaging bag in which the packaged item is contained.

In this specification, the handle portion refers to a part of the packaging bag that can be held by grasping (or gripping) with the palm, fingers, etc. (hereinafter referred to as fingers). The adhesive portion refers to a portion that can be attached to the main body of the packaging bag and can be peeled off from the main body and reattached. Extending from the handle portion means that the adhesive portion extends outward from the handle portion, continuing from the handle portion.

In the first aspect, the adhesive part extends from a handle part formed on the top surface of the main body part in which the packaged item is contained, so that the adhesive part extending from the handle part can be attached to the packaging bag after opening. This allows the handle part of the packaging bag and its surrounding part (the part of the main body part close to the handle part) to close the opening formed in the main body part by opening the packaging bag. Therefore, dust and dirt (hereinafter sometimes referred to as dust) from the outside is less likely to enter the packaging bag after opening, and unused items can be stored hygienically.

In addition, in the first aspect, the adhesive part extending from the handle part can be attached to parts of the main body part that are highly uneven (or have a large unevenness) when the opened packaging bag contains an item. Therefore, the adhesive part can be attached so as to minimize the creation of gaps inside the opened packaging bag containing the item. This prevents the item contained in the opened packaging bag from collapsing inside the packaging bag or flying out of the packaging bag during storage, allowing it to be stored stably.

The second aspect of the present invention is a packaging bag in which the adhesive part extending from the handle is constituted by a part of the handle. In this specification, "constituted by a part of the handle" means that a part of the handle itself constitutes the adhesive part.

In the second aspect, the adhesive part extending from the handle is constructed from a part of the handle, so that the handle of the packaging bag can be effectively utilized even after the packaging bag is opened. In addition, the adhesive part extending from the handle can be constructed without using a separate member from the handle, so that an increase in product costs can be suppressed.

A third aspect of the present invention is a packaging bag in which the adhesive portion extending from the handle portion is formed at each of both longitudinal ends of the handle portion. In this specification, the longitudinal direction of the handle portion refers to the direction in which the side ends of the handle portion face each other. Both longitudinal ends of the handle portion refer to the portions near each side end, including each side end of the handle portion.

In the third aspect, the adhesive portion extending from the handle is formed at both longitudinal ends of the handle, so that a pair of adhesive portions can be formed at both longitudinal ends of the handle. Therefore, the adhesive portion extending from the handle can be attached to two locations over a wide range of the main body of the packaging bag. This increases the degree of freedom with which the adhesive portion can be attached to the main body of the packaging bag.

The fourth aspect of the present invention is a packaging bag in which the handle portion has a pair of fold-back portions folded back from both ends, and the adhesive portion extending from the handle portion is constituted by at least a part of the fold-back portions. In this specification, the fold-back portions are the portions that are folded back from each end of the handle portion and overlap the ends. "Constituted by at least a part of the fold-back portions" means that all or a part of the fold-back portions themselves constitute the adhesive portion.

In the fourth aspect, the adhesive part extending from the handle is configured by such a folded part of the handle, so that the adhesive part extending from the handle can be provided without interfering with the original function of the handle (such as being able to be grasped with the fingers). In addition, by configuring the adhesive part using such a folded part, the adhesive part extending from the handle can be reliably provided without using a separate member from the handle.

A fifth aspect of the present invention is a packaging bag in which the handle is provided with a first cutout for forming an adhesive part extending from the handle. In this specification, the first cutout is one or a series of multiple slits or notches, which form an adhesive part when broken. In the fifth aspect, because such a first cutout is provided in the handle, the adhesive part can be extended only when an adhesive part is needed after the packaging bag is opened.

A sixth aspect of the present invention is a packaging bag in which the adhesive portion extending from the handle portion extends in the longitudinal direction of the handle portion. In this specification, "extending in the longitudinal direction of the handle portion" means that the adhesive portion extending from the handle portion extends to the outside of the handle portion along the longitudinal direction of the handle portion. In the sixth aspect, the adhesive portion extending from the handle portion extends in the longitudinal direction of the handle portion, so that the degree of freedom with which the adhesive portion can be attached to the main body portion of the packaging bag can be increased along the longitudinal direction of the handle portion.

A seventh aspect of the present invention is a packaging bag in which the adhesive portion extending from the handle portion extends in a width direction intersecting with the longitudinal direction of the handle portion. In this specification, "extending in a width direction intersecting with the longitudinal direction of the handle portion" means that the adhesive portion extending from the handle portion extends to the outside of the handle portion along a width direction intersecting with the longitudinal direction of the handle portion. In the seventh aspect, the adhesive portion extends in the width direction of the handle portion, so that the degree of freedom with which the adhesive portion can be attached to the main body portion can be increased along the width direction of the handle portion.

The eighth aspect of the present invention is a packaging bag in which the adhesive portion extending from the handle portion is formed in the center of the handle portion in the longitudinal direction. In this specification, the center of the handle portion in the longitudinal direction refers to a portion that includes the center of the handle portion and its periphery, and occupies a range of between about one-third and one-half of the entire handle portion in the longitudinal direction of the handle portion.

In the eighth aspect, the adhesive part extending from the handle is formed in the longitudinal center of the handle, so that the adhesive part extending from the center of the handle can be attached to the main body of the packaging bag. This increases the degree of freedom with which the adhesive part can be attached to the main body of the packaging bag.

A ninth aspect of the present invention is a packaging bag in which a second cut portion for opening the main body portion is provided on the top surface. In this specification, the second cut portion is one or a series of multiple slits or notches, which, when broken, open the main body portion.

In the ninth aspect, because such a second cut is provided on the top surface, after the packaging bag is opened, the opening formed in the main body part can be easily closed by attaching the adhesive part extending from the handle part to the main body part. This makes it more difficult for dust to get into the packaging bag from the outside after it has been opened, allowing unused items to be stored more hygienically.

According to one aspect of the present invention, a packaging bag that has excellent storage properties after opening can be provided.

In Figs. 1 and 2, the packaging bag 100 according to the first embodiment includes a main body portion 10 and a handle portion 20. The packaging bag 100 is an example of the packaging bag 100 according to the present invention. The main body portion 10 and the handle portion 20 are also examples of the main body portion and the handle portion that constitute the packaging bag according to the present invention.

The main body 10 constitutes the main body (bag body) of the packaging bag 100 in which the packaged item R is contained. The main body 10 can be formed from a resin film or the like. The main body 10 is structured such that this resin film is formed into a cylindrical shape by side sealing and further folded into a gusset shape. The material of the main body 10 is not limited to resin and may be paper. The material of the main body 10 may also be a biodegradable material (biodegradable plastic, biodegradable paper, etc.).

When the main body 10 is formed from a resin film, the material of the resin film is not particularly limited, and examples thereof include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and a laminate of PE-ethylene vinyl alcohol copolymer (EVOH)-PE (PE/EVOH/PE). In addition, the thickness of the resin film is not particularly limited, and can be 10 μm or more and 70 μm or less, preferably 15 μm or more and 60 μm or less, and more preferably 20 μm or more and 50 μm or less.

As shown in Fig. 1, when the packaged object R is housed in the main body 10, the main body 10 has a top surface 11, a bottom surface 12, a front surface 13, a rear surface 14, a side surface 15, and a side surface 16. Of the sides of the main body 10, the top surface 11 and the bottom surface 12 face each other in the up-down direction (Y direction), the front surface 13 and the rear surface 14 face each other in the front-to-back direction (Z direction), and the side surface 15 and the side surface 16 face each other in the left-to-right direction (X direction).

Of the surfaces of the main body 10, the top surface 11 is located at the top in the vertical direction (Y direction), and the bottom surface 12 is located at the bottom in the vertical direction (Y direction). The front surface 13 is located at the front in the front-to-back direction (Z direction), and the back surface 14 is located at the rear in the front-to-back direction (Z direction). Furthermore, the side surface 15 is located on the left in the horizontal direction (X direction), and the side surface 16 is located on the right in the horizontal direction (X direction). The side surfaces 15 and 16 are continuous with the top surface 11, bottom surface 12, front surface 13, and back surface 14 (see Figure 1).

Furthermore, when the packaged object T is contained in the main body 10, the top surface 11 has an upper top surface TA and a lower top surface TB that overlaps with a part of the upper top surface TA. To facilitate understanding of the relationship between the upper top surface TA and the lower top surface TB, in Figures 1 and 2, the upper top surface TA is shown slightly elevated above the lower top surface TB.

As shown in Figures 1 and 2, the upper top surface TA is continuous with the front surface 13 and rear surface 14 of the main body 10, and further has a folded portion (not shown) of approximately the same shape as the lower top surface TB, which is continuous with the lower top surface TB. The lower top surface TB is also continuous with a pair of side surfaces 15, 16 of the main body 10, and further continues with the folded portion (not shown) of the upper top surface TA.

The packaged object R is an item such as sanitary paper that is contained in the packaging bag 100. In this embodiment, 12 rolls of toilet paper (hereinafter referred to as toilet rolls) are contained in the main body 10 as an example of the packaged object R (see Figures 1 and 2). The shape of the packaged object R is not limited to a roll, and may be contained in other shapes such as a stacked shape. Furthermore, the packaged object R contained in the main body 10 is not limited to toilet paper, and may contain items such as kitchen paper, paper towels, baby or nursing care diapers, and sanitary napkins.

In the example shown in FIG. 1 (first embodiment), 12 rolls of toilet paper (packaged items R) are stored in the main body 10 with 4 rolls per layer stacked in 3 layers. In the example shown in FIG. 2 (a modified version of the first embodiment), 12 rolls of toilet paper (packaged items R) are stored in the main body 10 with 12 rolls per layer. The number of packaged items R stored in the main body 10 is not limited, and may be one, or may be multiple as shown in FIGS. 1 and 2. The arrangement of the packaged items stored in the main body 10 is not limited to the arrangement shown in FIGS. 1 and 2.

The main body 10 is optionally provided with a cutout 11B. The position of the cutout 11B on the main body 10 is not particularly limited, but it is preferable to provide the cutout 11B on the top surface 11 of the main body 10. The cutout 11B is one or a series of multiple slits or notches, and when broken, the main body 10 is opened.

In this embodiment, as shown in Figures 1 and 2, the cutout 11B is a linear slit that extends along the longitudinal direction (X direction) of the handle 20, and is formed between the center 11a of the top surface 11 and the edge 11c on the front surface 13 side. Here, the longitudinal direction of the handle 20 refers to the direction in which the side ends 23a, 24a of the handle 20 face each other (X direction).

The cutout 11B formed in the top surface 11 may be formed in at least the top surface upper portion TA (including the folded portion) of the top surface 11. In other words, the cutout 11B may be formed only in the top surface upper portion TA of the top surface 11, or may be formed in the top surface upper portion TA (including the folded portion) and the top surface lower portion TB of the top surface 11.

The shape of the cutout 11B is not limited to a straight line, but can be a curve, triangle, square, circle, U-shape, etc. The dimensions of the cutout 11B are not particularly limited, and can be determined based on the dimensions and number of the packaged objects R to be contained in the main body 10.

The slit constituting the cut portion 11B can be formed, for example, by a perforation, and by breaking the perforation, an opening OP is formed in the top surface 11 of the main body 10, and the packaged object R contained in the main body 10 can be removed from the opening OP. The cut portion 11B is an example of a second cut portion for opening the main body 10.

As shown in FIG. 1, the handle 20 is formed on the top surface 11 of the main body 10. The handle 20 constitutes a part of the packaging bag 100 that allows the packaging bag 100 to be held by grasping (or gripping) the packaging bag 100 with the fingers. The handle 20 is an example of a handle of a packaging bag according to the present invention.

The shape of the handle 20 is not particularly limited, but for example, the contour shape when viewed in the thickness direction of the handle 20 or the front-to-back direction (Z direction) of the packaging bag 100 can be a quadrangle such as a rectangle. Note that for ease of understanding, in Figs. 1 and 2, the handle 20 is shown standing up in the height direction (Y direction), but it is usually manufactured and sold in a state where it is laid down on the top surface 11 of the main body 10.

The dimensions of the handle 20 are not particularly limited and can be determined by the dimensions of the main body 10 and the finger hook 30 described below. When the shape of the handle 20 is rectangular, the dimensions of the handle 20 in the longitudinal direction (X direction) can be, for example, 150 mm or more and 500 mm or less, preferably 160 mm or more and 400 mm or less, and more preferably 170 mm or more and 300 mm or less. The dimensions of the handle 20 in the height direction (Y direction) can be 35 mm or more and 150 mm or less, preferably 40 mm or more and 130 mm or less, and more preferably 45 mm or more and 100 mm or less.

The handle 20 can be formed of a resin film or the like, similar to the main body 10. The handle 20 is formed on the top surface 11 of the main body 10. Specifically, the handle 20 is formed at the center 11a in the depth direction (Z direction) of the top surface 11 of the main body 10. The top surface 11 of the main body 10 (the position where the handle 20 is formed) is not limited to the top surface (upper surface) of the main body 10 as shown in FIG. 1, but may be any of the bottom surface, front surface, back surface, or side surface of the main body 10.

The handle portion 20 is made of resin film folded in a gusset shape, with four layers at both ends 23, 24 in the longitudinal direction (X direction) of the handle portion 20, and two layers near the center portion 25 in the longitudinal direction (X direction) of the handle portion 20, and is bonded by a seal portion 50 formed by heat sealing (thermal fusion). Note that the seal portion 50 is not limited to thermal fusion, and may be formed by applying an adhesive, pressure sensitive adhesive, etc.

As shown in FIG. 3, the seal portion 50 is made up of an upper end seal 51, a lower end seal 52, a side end seal 53, a side end seal 54, and an intermediate seal 55. The upper end seal 51 is provided along the upper end 21 side of the handle portion 20. In the example shown in FIG. 3, the upper end seal 51 is formed right up to the edge of the upper end 21 of the handle portion 20, but in the manufacturing process of the packaging bag 100, the upper end seal 51 may be formed so that the edge of the upper end 21 remains (is not sealed).

The bottom end seal 52 is provided along the bottom end 22 of the handle 20. The side end seal 53 is provided along the side end 23a of the handle 20 in the longitudinal direction (X direction) near the finger hook 30. The side end seal 54 is provided along the side end 24a of the handle 20 in the longitudinal direction (X direction) near the finger hook 30. The middle seal 55 is provided between the top end 21 (or top end seal 51) of the handle 20 and the finger hook 30, so as to extend continuously from the side end seal 53 to the side end seal 54.

As a result, a seal portion 50 (seals 51 to 55) is formed inside the handle portion 20. The portion surrounded by seals 51 to 54 constitutes the central portion 25 of the handle portion 20. It is preferable to provide an air hole (not shown) in the handle portion 20 that connects the main body portion 10 to the outside of the packaging bag 100 so that the main body portion 10 to which the handle portion 20 is attached does not burst during the manufacture or distribution of the packaging bag 100. The central portion 25 of the handle portion 20 includes the center of the handle portion 20 and its periphery, and refers to the portion that occupies a range of approximately one-third to one-half of the entire handle portion 20 in the longitudinal direction (X direction) of the handle portion 20.

As shown in Figs. 1 and 2, a finger hook 30 is formed in the center 25 of the handle 20. The finger hook 30 is formed with a slit, and constitutes a portion on which the fingers are hooked when grasping (or gripping) the handle 20. The shape of the slit that constitutes the finger hook 30 is not particularly limited, and for example, the slit can be formed with a perforation, and the finger hook 30 can be formed by breaking the perforation. Note that the perforation indicates an alternating arrangement of multiple cuts and ties (portions where there are no cuts between the cuts).

In this embodiment, the shape of the finger hook 30 is configured so that the center of the slit is curved so as to be convex toward the upper end 21 of the handle 20, and both ends of the slit are curved in an arc shape, as shown in Figures 1 to 3. Note that the shape of the finger hook 30 is not limited to such a curve, and may be any shape such as a straight line, a wavy line, a circle, an ellipse, a rectangle, or a shape similar to these.

In this embodiment, the finger hook 30 is formed with one slit (see Figures 1 to 3), but the number of slits is not limited. Therefore, the finger hook 30 may be formed with two or more slits, for example, it can be formed with two slits arranged at a predetermined distance in the longitudinal direction (X direction) of the handle 20.

The handle 20 may also have a reinforcing seal formed between the finger hook 30 and the seal 50 (e.g., intermediate seal 55) that is continuous with the seal 50 or is discontinuous with the seal 50. By providing such a reinforcing seal on the handle 20, the finger hook 30 is reinforced, and the handle 20 can be prevented from breaking.

In addition, in this embodiment, a reinforcing film 40 is provided on the handle portion 20. This reinforcing film 40 can be formed of a resin film. The reinforcing film 40 is fused to the handle portion 20 by a sealing portion 50. By providing such a reinforcing film 40, it is possible to reinforce the central portion 25 in the longitudinal direction (X direction) of the handle portion 20 where the finger hook portion 30 is formed.

The material of the reinforcing film 40 is not particularly limited, and may be the same as or different from the material of the resin film that constitutes the handle portion 20. Examples of such resin films include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), a laminate of PE-ethylene vinyl alcohol copolymer (EVOH)-PE (PE/EVOH/PE), and polyvinylidene chloride (PVDC).

The thickness dimension of the reinforcing film 40 is not particularly limited, and can be, for example, 20 μm or more, preferably 30 μm or more and 150 μm or less, and more preferably 50 μm or more and 130 μm or less. By setting the thickness dimension of the reinforcing film 40 within this range, it is possible to prevent the handle portion 20 from stretching or breaking.

As shown in Figures 1 to 4, a pair of fold-back portions 43, 44 are provided at both ends 23, 24 of the handle portion 20. Specifically, both ends 41, 42 of the reinforcing film 40 provided on the handle portion 20 are folded back from the ends 23, 24 of the handle portion 20 to form the fold-back portions 43, 44, and the fold-back portions 43, 44 constitute portions that overlap the ends 23, 24 of the handle portion 20.

The folded portion 43 has an edge 43A located closer to the side seal 53 and an edge 43B continuing with the end 41, and is fused to the handle portion 20 by the upper seal 51 and the lower seal 52 of the seal portion 50 (see FIG. 3). The folded portion 44 has an edge 44A located closer to the side seal 54 and an edge 44B continuing with the end 42, and is fused to the handle portion 20 by the upper seal 51 and the lower seal 52 of the seal portion 50 (see FIG. 3).

As shown in FIG. 3, the handle 20 has cuts 43C, 43D, 44C, and 44D. The cuts 43C, 43D, 44C, and 44D are one or a series of multiple slits or notches, and when broken, form an adhesive portion, which will be described later. Specifically, the cuts 43C and 43D are formed in the folded portion 43 of the reinforcing film 40 provided on the handle 20, and the cuts 44C and 44D are formed in the folded portion 44 of the reinforcing film 40.

In the folded portion 43, the notch 43C is provided closer to the top seal 51, and the notch 44C is provided closer to the bottom seal 52 (see FIG. 3). In the folded portion 44, the notch 44C is provided closer to the top seal 51, and the notch 44C is provided closer to the bottom seal 52 (see FIG. 3). The notches 43C, 43D, 44C, and 44D are examples of first notches provided in the handle portion of the packaging bag according to the present invention.

In the packaging bag 100 according to this embodiment, an adhesive portion 60 is provided at both ends 23, 24 of the handle portion 20. The adhesive portion 60 is composed of an adhesive member 61 provided at both ends 23 of the handle portion 20 and an adhesive member 61 provided at both ends 24 of the handle portion 20. Specifically, as shown in Figs. 3 and 4, the adhesive member 61 is provided between the end 41 of the reinforcing film 40 provided at the handle portion 20 and the folded-back portion 43, and the adhesive member 62 is provided between the end 42 of the reinforcing film 40 and the folded-back portion 44.

The material of the adhesive members 61, 62 constituting the adhesive portion 60 is not particularly limited, but is preferably a material that has enough adhesiveness (or stickiness) to be provided in the attachment portion described below, to allow the attachment portion to be attached to the main body portion 10 of the packaging bag 100, and to be peeled off from the main body portion 10 and reattached. For example, an acrylic ester resin is preferable as a material having such adhesiveness, and among them, a copolymer of polyacrylic ester and polyacrylic acid is more preferable.

In the packaging bag 100 according to this embodiment, as shown in FIG. 5, when the cuts 43C and 43D of the fold-back portion 43 in the reinforcing film 40 provided on the handle portion 20 are torn, a tag T1 provided with an adhesive portion 60 (adhesive member 61) is formed. When the cuts 44C and 44D of the fold-back portion 44 are torn, a tag T2 provided with an adhesive portion 60 (adhesive member 62) is formed.

Tag T1 is configured to extend from handle portion 20 with adhesive portion 60 (adhesive member 61) provided. Tag T2 is configured to extend from handle portion 20 with adhesive portion 60 (adhesive member 62) provided. Here, extending from handle portion 20 means that tags T1 and T2 extend outward (or to the outside) of handle portion 20 in continuity with handle portion 20.

In this embodiment, as shown in Figures 3 to 5, the tags T1 and T2 are configured to extend in the longitudinal direction (X direction) of the handle portion 20. Here, extending in the longitudinal direction (X direction) of the handle portion 20 means that the tags T1 and T2 extending from the handle portion 20 extend to the outside of the handle portion 20 along the longitudinal direction (X direction) of the handle portion 20.

Specifically, when the cuts 43C and 43D of the fold-back portion 43 in the reinforcing film 40 provided on the handle portion 20 are torn, the tag T1 provided with the adhesive portion 60 (adhesive member 61) can extend from the handle portion 20 along the longitudinal direction (X direction). When the cuts 44C and 44D of the fold-back portion 44 are torn, the tag T2 provided with the adhesive portion 60 (adhesive member 62) can extend from the handle portion 20 along the longitudinal direction (X direction).

Tags T1 and T2 are provided with an adhesive portion 60 (adhesive members 61 and 62) so that they can be attached to the main body 10 of the packaging bag 100, and can also be peeled off from the main body 10 and reattached. The tags T1 and T2 provided with the adhesive portion 60 are an example of an attachment portion extending from the handle portion of the packaging bag according to the present invention.

Looking at it from another perspective, such tags T1 and T2 are made up of part of the handle 20. In other words, a part of the handle 20 itself constitutes the attachment part (tags T1 and T2) on which the adhesive part 60 (adhesive member 61) is provided (see Figures 1 to 5).

As shown in Figures 3 to 5, tags T1 and T2 are formed on both ends 23 and 24 of the handle portion 20 in the longitudinal direction (X direction). Here, both ends 23 and 24 of the handle portion 20 in the longitudinal direction (X direction) refer to the portions of the handle portion 20 close to each side end 23a and 24a, including each side end 23a and 24a.

Specifically, the tags T1 and T2 are composed of at least a part of the folded-back portions 43 and 44 of the reinforcing film 40. Note that "composed of at least a part of the folded-back portions 43 and 44" means that all or a part of the folded-back portions 43 and 44 directly constitute the attachment portion (tags T1 and T2). In this embodiment, as shown in Figures 1 to 5, a part of the folded-back portions 43 and 44 directly constitutes the tags T1 and T2.

Figures 6 to 8 are diagrams showing how the packaging bag according to this embodiment is used. In this embodiment, first, in the packaging bag 100 shown in Figure 1 (a packaging bag in which 12 toilet rolls R are stored in the main body 10), the cut portion 11B in the top surface 11 is torn to form an opening OP in the top surface 11 of the main body 10.

The top two toilet rolls R are removed from the opening OP formed on the top surface 11 of the main body 10. Then, with the two toilet rolls R removed from the main body 10, the attachment parts (tags T1, T2 with adhesive parts 60) extending from the handle part 20 are affixed to the sides 15, 16 of the main body 10 so that the handle part 20 covers (or closes) the opening OP (see Figure 6).

The tags T1 and T2 attached to the sides 15 and 16 of the main body 10 are peeled off, and one more toilet roll R (for a total of three) is removed from the opening OP of the main body 10. Then, with the three toilet rolls R removed from the main body 10, the tags T1 and T2 with the adhesive portion 60 are attached again to the main body 10 so that the handle portion 20 covers the opening OP (see FIG. 7).

The tags T1 and T2 attached to the main body 10 are then peeled off, and five more toilet rolls R (for a total of eight) are removed from the opening OP of the main body 10. Then, with the eight toilet rolls R having been removed from the main body 10, the tags T1 and T2 are attached to the main body 10 so that the handle 20 covers the opening OP (see FIG. 8).

In this embodiment, the adhesive portion (tags T1, T2) extends from the handle portion 20 formed on the top surface 11 of the main body portion 10 in which the packaged item R is contained, so that the adhesive portion (tags T1, T2) extending from the handle portion 20 can be attached to the packaging bag 100 after it has been opened (see Figures 6 to 8).

In this embodiment, with this configuration, the handle portion 20 of the packaging bag 100 and its surrounding portion (the portion of the main body portion 10 close to the handle portion 20) can close the opening OP formed in the main body portion 10 when the packaging bag 100 is opened. Therefore, dust and dirt (hereinafter sometimes referred to as dust) is less likely to enter the packaging bag 100 from the outside after it has been opened, and unused toilet rolls (packaged object R) can be stored hygienically.

In addition, in this embodiment, the adhesive portion (tags T1, T2) extending from the handle portion 20 can be attached to parts of the main body portion 10 that are highly uneven (or have a large amount of unevenness) when the toilet roll (packaged item R) is contained in the packaging bag 100 after opening (see Figures 6 to 8).

In this configuration, the attachment parts (tags T1, T2) can be attached so as to minimize the creation of gaps inside the opened packaging bag 100 containing the toilet roll (packaged item R). As a result, in this embodiment, the toilet roll (packaged item R) contained in the opened packaging bag 100 is prevented from collapsing inside the packaging bag 100 or popping out of the packaging bag 100 during storage, allowing for stable storage.

In addition, in this embodiment, as described above, the adhesive portion (tags T1, T2) extending from the handle portion 20 is configured as part of the handle portion 20, so that the handle portion 20 of the packaging bag 100 can be effectively utilized even after the packaging bag 100 is opened. In addition, since the adhesive portion (tags T1, T2) extending from the handle portion 20 can be configured without using a separate member from the handle portion 20, an increase in product costs can be suppressed.

In addition, in this embodiment, as described above, the adhesive parts (tags T1, T2) are formed at both ends 23, 24 of the handle part 20 in the longitudinal direction (X direction), so that a pair of adhesive parts (tags T1, T2) can be formed at both ends 23, 24 of the handle part 20 in the longitudinal direction (X direction). Therefore, the adhesive parts (tags T1, T2) extending from the handle part 20 can be attached to two locations over a wide range of the main body part 10 of the packaging bag 100. As a result, in this embodiment, the degree of freedom in attaching the adhesive parts (tags T1, T2) to the main body part 10 of the packaging bag 100 can be increased.

In addition, in this embodiment, as described above, the adhesive portion (tags T1, T2) extending from the handle portion 20 is formed by the folded portions 43, 44 of the handle portion 20, so that the adhesive portion (tags T1, T2) extending from the handle portion 20 can be provided without interfering with the original function of the handle portion 20 (such as being able to be grasped with fingers). In addition, by forming the adhesive portion (tags T1, T2) using such folded portions 43, 44, the adhesive portion (tags T1, T2) extending from the handle portion 20 can be reliably provided without using a member separate from the handle portion 20.

In addition, in this embodiment, as described above, the first cut portions (cut portions 43C, 43D, 44C, 44D) are provided in the reinforcing film 40 of the handle portion 20, so that the affixed portions (tags T1, T2) can be extended only when they are needed after the packaging bag 100 is opened.

In addition, in this embodiment, as described above, the adhesive portion (tags T1, T2) extending from the handle portion 20 extends in the longitudinal direction (X direction) of the handle portion 20, so that the degree of freedom with which the adhesive portion (tags T1, T2) can be attached to the main body portion 10 of the packaging bag 100 can be increased along the longitudinal direction (X direction) of the handle portion 20.

Furthermore, in this embodiment, because the cut portion 11B is provided on the top surface 11 as described above, after the packaging bag 100 is opened, the opening OP formed on the top surface 11 of the main body portion 10 can be easily closed by attaching the adhesive portion (tags T1, T2) to the main body portion 10. This makes it more difficult for dust to enter the packaging bag 100 from the outside after it has been opened, allowing unused toilet rolls (packaged object R) to be stored more hygienically.

Figure 9 is a diagram showing the handle portion of a packaging bag according to a second embodiment of the present invention. Figure 10 is a cross-sectional view of line B-B in Figure 9. Figure 11 is a diagram showing the adhesive portion of the packaging bag shown in Figure 9 when unfolded. In each figure, parts that are common to the first embodiment are given the same reference numerals and will not be described.

As shown in Figs. 9 to 11, in the packaging bag 100 according to the second embodiment, the adhesive parts (tags T1, T2) are configured to extend in a width direction (Y direction) that intersects with the longitudinal direction (X direction) of the handle part 20. Here, extending in a width direction (Y direction) that intersects with the longitudinal direction (X direction) of the handle part 20 means that the adhesive parts (tags T1, T2) extending from the handle part 20 extend to the outside of the handle part 20 along a width direction (Y direction) that intersects with the longitudinal direction (X direction) of the handle part 20.

Specifically, in the reinforcing film 40 provided on the handle portion 20, the cutout portion 43C provided on the fold-back portion 43 is positioned closer to the side end 23a of the handle portion 20, and the cutout portion 44C provided on the fold-back portion 44 is positioned closer to the side end 24a of the handle portion 20 (see Figures 9 and 10).

When the cuts 43C and 43D of the fold-back portion 43 are torn, the tag T1 provided with the adhesive portion 60 (adhesive member 61) can extend from the handle portion 20 in the width direction (Y direction) (see FIG. 11). When the cuts 44C and 44D of the fold-back portion 44 are torn, the tag T2 provided with the adhesive portion 60 (adhesive member 62) can extend from the handle portion 20 in the width direction (Y direction) (see FIG. 11).

In this embodiment, the adhesive portion (tags T1, T2) extends in the width direction (Y direction) of the handle portion 20 in this manner, thereby increasing the degree of freedom with which the adhesive portion (tags T1, T2) can be attached to the main body portion 10 along the width direction (Y direction) of the handle portion 20.

It should be noted that, of the tags T1 and T2 extending from the handle portion 20, it is sufficient that one of the tags extends in the width direction (Y direction) of the handle portion 20, and the other tag may extend in the longitudinal direction (X direction) of the handle portion 20. This configuration further increases the degree of freedom with which the attachment portion (tags T1 and T2) can be attached to the main body portion 10.

In addition, in this embodiment, after the cuts 43C, 43D, 44C, and 44D of the fold-back portions 43 and 44 are torn, the adhesive portion 60 is provided only on the tags T1 and T2, but this is not limited to the configuration. For example, after the cuts 43C, 43D, 44C, and 44D of the fold-back portions 43 and 44 are torn, the adhesive portion 60 may remain on both ends 23 and 24 of the handle portion 20 (both ends 41 and 42 of the reinforcing film 40). With this configuration, both ends 23 and 24 of the handle portion 20 (both ends 41 and 42 of the reinforcing film 40) can also be attached to the main body portion 10.

Figure 12 is a diagram showing the handle portion of a packaging bag according to a third embodiment of the present invention. Figure 13 is a cross-sectional view taken along line C-C in Figure 12. Figure 14 is a diagram showing the adhesive portion of the packaging bag shown in Figure 12 in an expanded form. Note that in each figure, parts common to the first embodiment are given the same reference numerals and will not be described.

As shown in Figures 12 and 13, in the packaging bag 100 according to the third embodiment, the folded-back portions 43, 44 are not provided at both ends 23, 24 of the handle portion 20. The tag T1 is formed from a part of the end 23 of the handle portion 20. The tag T2 is formed from a part of the end 24 of the handle portion 20 (see Figures 12 to 14).

Specifically, cuts 41A, 41B, and 41C are provided on end 41 of reinforcing film 40 at end 23 of handle 20, and 42A, 42B, and 42C are provided on end 42 of reinforcing film 40 at end 24 of handle 20 (see Figures 12 and 13). Cuts 41A, 41B, 41C, 42A, 42B, and 42C are one or a series of multiple slits or notches, and when broken, an attachment part (tag T1, T2) is formed.

In this embodiment, at the end 41 of the reinforcing film 40, the cut portion 41A is provided closer to the side seal 53, the cut portion 41B is provided closer to the top seal 51, and the cut portion 41C is provided closer to the bottom seal 52 (see FIG. 12). In this embodiment, the cut portions 41A, 41B, and 41C are configured as a whole with U-shaped (or approximately U-shaped) perforations. The cut portions 41A, 41B, and 41C are an example of a first cut portion provided in the handle portion of the packaging bag according to the present invention.

At the end 42 of the reinforcing film 40, the cut portion 42A is provided closer to the side seal 54, the cut portion 41B is provided closer to the top seal 51, and the cut portion 41C is provided closer to the bottom seal 52 (see FIG. 12). In this embodiment, the cut portions 42A, 42B, and 42C are configured as perforations that are in an inverted U-shape (or approximately U-shaped) as a whole. The cut portions 42A, 42B, and 42C are an example of a first cut portion provided in the handle portion of the packaging bag according to the present invention.

In this embodiment, the adhesive portion 60 (adhesive member 61) is provided between the end 23 of the handle portion 20 and the end 41 of the reinforcing film 40 (see Figures 12 and 13). The adhesive portion 60 (adhesive member 62) is provided between the end 24 of the handle portion 20 and the end 42 of the reinforcing film 40 (see Figures 12 and 13).

When the cuts 41A, 41B, and 41C of the end 41 of the reinforcing film 40 provided on the handle 20 are torn, the tag T1 provided with the adhesive portion 60 (adhesive member 61) can extend from the handle 20 along the longitudinal direction (X direction). When the cuts 42A, 42B, and 42C of the end 42 are torn, the tag T2 provided with the adhesive portion 60 (adhesive member 62) can extend from the handle 20 along the longitudinal direction (X direction).

In this embodiment, as described above, the adhesive parts (tags T1, T2) extending from the handle part 20 are formed from parts of both ends 41, 42 of the reinforcing film 40 provided on the handle part 20, so that the handle part 20 of the packaging bag 100 can be effectively utilized even after the packaging bag 100 is opened. In addition, the adhesive parts (tags T1, T2) extending from the handle part 20 can be formed without using a member separate from the handle part 20 and without providing the fold-back parts 43, 44 on the reinforcing film 40, so that an increase in product costs can be further suppressed.

In addition, in this embodiment, the attachment parts (tags T1, T2) extending from the handle part 20 extend in the longitudinal direction (X direction) of the handle part 20, so that the degree of freedom with which the attachment parts (tags T1, T2) can be attached to the main body part 10 of the packaging bag 100 can be increased along the longitudinal direction (X direction) of the handle part 20 without providing fold-back parts 43, 44 on the reinforcing film 40.

Figure 15 is a diagram showing the handle portion of a packaging bag according to a fourth embodiment of the present invention. Figure 16 is a cross-sectional view taken along line D-D in Figure 15. Figure 17 is a diagram showing the adhesive portion of the packaging bag shown in Figure 15 in an expanded form. Note that in each figure, parts common to the third embodiment are given the same reference numerals and will not be described.

As shown in Figures 15 and 16, in the packaging bag 100 according to the fourth embodiment, similar to the third embodiment, the folded-back portions 43, 44 are not provided at both ends 23, 24 of the handle portion 20. The tag T1 is formed from a part of the end 23 of the handle portion 20. The tag T2 is formed from a part of the end 24 of the handle portion 20 (see Figures 15 to 17).

In this embodiment, the cutout 41B is provided at the end 41 of the reinforcing film 40 near the side end 23a of the handle 20, and the cutouts 41A, 41B, and 41C are configured as inverted U-shaped (or roughly U-shaped) perforations. The cutouts 41A, 41B, and 41C are an example of a first cutout provided in the handle of the packaging bag according to the present invention.

In this embodiment, the cutout 42B is provided at the end 42 of the reinforcing film 40 near the side end 24a of the handle 20, and the cutouts 42A, 42B, and 42C are configured as inverted U-shaped (or roughly U-shaped) perforations. The cutouts 42A, 42B, and 42C are an example of a first cutout provided in the handle of the packaging bag according to the present invention.

When the cuts 41A, 41B, and 41C of the end 41 of the reinforcing film 40 provided on the handle 20 are torn, the tag T1 provided with the adhesive portion 60 (adhesive member 61) can extend from the handle 20 along the width direction (Y direction). When the cuts 42A, 42B, and 42C of the end 42 are torn, the tag T2 provided with the adhesive portion 60 (adhesive member 62) can extend from the handle 20 along the width direction (Y direction).

After the tag T1 is extended from the handle portion 20, an exposed portion 20A appears at the end 23 of the handle portion 20, and after the tag T2 is extended from the handle portion 20, an exposed portion 20B appears at the end 24 of the handle portion 20 (see FIG. 20). In this embodiment, the adhesive portion 60 is provided only on the tags T1 and T2 extending from the handle portion 20, but by leaving the adhesive portion 60 on the exposed portions 20A and 20B, both ends 23 and 24 of the handle portion 20 can also be attached to the main body portion 10.

In this embodiment, the adhesive parts (tags T1, T2) extend in the width direction (Y direction) of the handle part 20 in this manner, so that the degree of freedom with which the adhesive parts (tags T1, T2) can be attached to the main body part 10 can be increased along the width direction (Y direction) of the handle part 20 without providing fold-back parts 43, 44 on the reinforcing film 40.

In this embodiment, the handle 20 does not have fold-back portions 43, 44 at both ends 23, 24, and both of the attachment portions (tags T1, T2) are formed from a portion of both ends 41, 42 of the reinforcing film 40, but this is not limited to the above configuration. Therefore, for example, a fold-back portion may be provided at either end 23, 24 of the handle 20, and one of the tags T1, T2 that make up the attachment portion may be formed from a portion of the end of the reinforcing film 40, and the other tag may be formed from a portion of the fold-back portion.

Figure 18 is a diagram showing the handle portion of a packaging bag according to a fourth embodiment of the present invention. Figure 19 is a cross-sectional view of line E-E in Figure 18. Figure 20 is a diagram showing the adhesive portion of the packaging bag shown in Figure 18 when unfolded. In each figure, parts that are common to the fourth embodiment are given the same reference numerals and will not be described.

As shown in Figs. 18 and 19, in the packaging bag 100 according to the fifth embodiment, like the fourth embodiment, the folded-back portions 43, 44 are not provided at both ends 23, 24 of the handle portion 20. The tag T3 is formed at the center portion 25 in the longitudinal direction (X direction) of the handle portion 20 (see Figs. 18 to 20).

Specifically, in the central portion 45 of the reinforcing film 40, the cutout portion 45A is provided adjacent to one end (the portion curved in an arc) of the finger hook portion 30 (slit) and is located closer to the side end seal 53. The cutout portion 45B is provided adjacent to the other end (the portion curved in an arc) of the finger hook portion 30 (slit) and is located closer to the side end seal 54. The cutout portions 45A and 45B are formed by a substantially U-shaped perforation together with the central portion of the finger hook portion 30 (slit) (see Figures 18 and 19). The cutout portions 45A and 45B are an example of a first cutout portion provided in the handle portion of the packaging bag according to the present invention.

In this embodiment, the adhesive portion 60 (adhesive member 63) is provided between the central portion 25 of the handle portion 20 and the central portion 45 of the reinforcing film 40 (see Figures 18 and 19). The adhesive portion 60 (adhesive member 62) is provided between the end portion 24 of the handle portion 20 and the end portion 42 of the reinforcing film 40 (see Figures 18 and 19).

When the slit in the finger hook portion 30 of the reinforcing film 40 provided on the handle portion 20 is torn and the cutouts 45A and 45B in the center portion 45 are further torn, the tag T3 provided with the adhesive portion 60 (adhesive member 63) can extend out from the handle portion 20 in the width direction (Y direction).

After the tag T3 is extended from the handle 20, an exposed portion 20C appears at the center 25 of the handle 20 (see FIG. 20). In this embodiment, the adhesive portion 60 is provided only on the tag T3 extending from the handle 20, but by leaving the adhesive portion 60 on the exposed portion 20C as well, the center 25 of the handle 20 can also be attached to the main body 10.

In the fifth embodiment, the seal portion 50 does not include an intermediate seal 55, taking into consideration that the tag T3 extends from the center portion 25 of the handle portion 20. However, this embodiment does not exclude a configuration in which the seal portion 50 includes an intermediate seal 55.

In this embodiment, the attachment portion (tag T3 provided with adhesive member 63) extending from the handle portion 20 is formed in the central portion 25 of the handle portion 20 in the longitudinal direction (X direction), so that the attachment portion (tag T3) extending from the central portion 25 of the handle portion 20 can be attached to the main body portion 10 of the packaging bag 100. This allows the degree of freedom with which the attachment portion (tag T3) can be attached to the main body portion 10 of the packaging bag 100 to be expanded to the range in which the attachment portion (tag T3) extends from the central portion 25 of the handle portion 20.

In the fifth embodiment, the attachment portion (tag with an adhesive portion) extending from the handle portion 20 is configured as tag T3, but is not limited to this configuration. For example, the attachment portion (tag with an adhesive portion) extending from the handle portion 20 may be configured such that two attachment portions (tags T1, T2) extend from both ends 23, 24 of the handle portion 20 and one attachment portion (tag T3) extends from the center portion 25 of the handle portion 20. By providing three such attachment portions (tags T1 to T3), the degree of freedom with which the attachment portions (tags T1 to T3) can be attached to the main body portion 10 can be further increased.

The present invention will now be described in more detail with reference to examples. The examples and comparative examples were evaluated using the following tests.

[Packaging bag (test specimen)]
As a test specimen, a packaging bag 100 having a handle portion 20 formed on the top surface 11 of the main body portion 10 is prepared (see FIG. 1). The packaging bag 100 is made of a polyethylene (PE) film having a thickness of about 25 μm. The packaging bag 100 is formed by forming the PE film into a cylindrical shape by side sealing, folding it into a gusset shape, and sealing the top surface 11 of the main body portion 10 by heat sealing so that the handle portion 20 is integrally formed with the top surface 11 of the main body portion 10. The handle portion 20 has an attachment portion (a tag provided with an adhesive portion 60) extending from the handle portion 20. The top surface 11 of the main body portion 10 (top surface upper portion TA including a folded portion not shown) has a cut portion 11B (a linear slit extending along the longitudinal direction (X direction) of the handle portion 20) formed between the center 11a of the top surface 11 and the edge 11c on the front surface 13 side. The main body 10 contained 12 rolls of toilet paper ("Elleair Toilet Tissue 60 m Single (147 g/roll)" manufactured by Daio Paper Co., Ltd.) (hereinafter referred to as "toilet rolls") as the packaged item R, stacked in three tiers with four rolls in each tier (see FIG. 1).

[Ease of application]
For the packaging bag 100, the cut portion 11B of the top surface 11 is torn, and two toilet rolls are removed from the opening OP of the opened main body portion 10. Then, the attachment portion (a tag provided with an adhesive portion 60) extending from the handle portion 20 is attached to the main body portion 10 so that the handle portion 20 covers (or closes) the opening OP (see FIG. 21). The ease of attachment (ease of application) of the attachment portion at this time was evaluated. The ease of application was evaluated according to the following criteria, with an evaluation of ◎ or ○ being good and an evaluation of △ or × being bad.
◎ Very easy to apply○ Easy to apply△ Difficult to apply× Cannot apply

[Tightness]
After measuring the ease of application as described above, the attachment part (tag provided with adhesive part 60) extending from handle part 20 was attached to main body part 10, and the height difference H3 (mm) obtained by subtracting the height H2 (mm) of the contained packaged object from the height H1 (mm) of the packaging film was measured (see FIG. 21). The tightness was evaluated according to the following criteria, with a height difference H3 of less than 30 mm (◎ or ◯) being considered good, and 30 mm or more (△ or ×) being considered bad.
◎ Height difference H3 is less than 10 mm ○ Height difference H3 is 10 mm or more and less than 30 mm △ Height difference H3 is 30 mm or more and less than 40 mm × Height difference H3 is 40 mm or more

[Storage stability]
After measuring the tightness as described above, the packaging bag 100 was turned over onto the front surface 13 of the main body 10 with the attachment portion (tag provided with the adhesive portion 60) extending from the handle portion 20 attached to the main body 10 (see FIG. 22). The storage state (storage stability) of the toilet roll at this time was evaluated. The storage stability was evaluated according to the following criteria, with ○ being good and △ or × being bad.
〇 The toilet roll did not crumble or pop out. △ The toilet roll crumbled. × The toilet roll popped out.

The following describes examples and comparative examples.

The packaging bag 100 was produced and evaluated in the same manner as in Example 1. The results are shown in Table 1.

[Example 4]
Except for the fact that the adhesive parts (tags T1, T2) extend from the handle part 20 in the width direction (Y direction) (see Figs. 15 to 17), the packaging bag 100 was produced and evaluated in the same manner as in Example 3. The results are shown in Table 1.

[Example 5]
A packaging bag 100 was produced and evaluated in the same manner as in Example 3, except that, instead of the adhesive parts (tags T1 and T2), the adhesive part (tag T3) was formed from a part of the central part 45 of the reinforcing film 40 provided on the handle part 20, and when the cut parts 45A and 45B of the central part 45 were torn, the adhesive part (tag T3) extended in the width direction (Y direction) from the handle part 20 (see Figs. 18 to 20). The results are shown in Table 1.

[Example 6]
A packaging bag 100 was produced and evaluated in the same manner as in Example 3, except that in addition to the adhesive parts (tags T1, T2), the adhesive part (tag T3) was formed from a part of the central part 45 of the reinforcing film 40 provided on the handle part 20, and when the cut parts 45A, 45B of the central part 45 were torn, the adhesive part (tag T3) extended in the width direction (Y direction) from the handle part 20 (not shown). The results are shown in Table 1.

[Comparative Example 1]
Except for not providing the adhesive parts (tags T1, T2) (see Figs. 23 and 24), a packaging bag was produced and evaluated in the same manner as in Example 3. The results are shown in Table 1.

[Comparative Example 2]
A packaging bag was produced and evaluated in the same manner as in Comparative Example 1, except that, instead of the adhesive parts (tags T1 and T2), a continuous adhesive part was provided (not shown) on the inside near the top surface 11 of the main body 10, spanning the front surface 13, back surface 14, and side surfaces 15 and 16. The results are shown in Table 1.

As can be seen from Table 1, the packaging bag 100 in which the attachment portion (tags T1 and T2 with adhesive portion 60) extends from the handle portion 20 was excellent in ease of attachment, tightness, and storage stability (Examples 1 to 6).

In contrast, packaging bags without adhesive parts (tags T1 and T2) were poor in ease of application, tightness, and storage stability (Comparative Examples 1 and 2).

From these results, it can be said that a packaging bag having a main body portion in which the packaged item is housed, a handle portion formed on the top surface of the main body portion, and an adhesive portion extending from the handle portion can store unused items hygienically and stably, and has excellent storage properties after opening.

Although the embodiment of the present invention has been described above, the present invention is not limited to a specific embodiment, and various modifications and variations are possible within the scope of the invention described in the claims.
