Description

  TECHNICAL FIELD The present invention relates to a packaging bag in which contents can be mixed.

  For example, Japanese Unexamined Patent Application Publication No. 2005-112451 discloses a packaging bag having two or more objects-to-be-packaged accommodation chambers. In this packaging bag, laminated films are laminated on the front and back, and outer peripheral edge portions are fusion-bonded to each other. Further, the packaging bag defines two package accommodation chambers with the central vertical seal portion interposed therebetween.

  In this packaging bag, different types of articles to be packaged are accommodated in the respective article accommodation chambers defined by the partition seal portion. Then, in a state where the central vertical seal portion is bent, it is possible to take out the contained objects accommodated in the two object accommodation chambers simultaneously or individually without soiling the hands.

JP, 2005-112451, A

  However, the packaging bag described in Japanese Patent Laid-Open No. 2005-112451 can accommodate different types of objects to be contained, but the objects to be contained cannot be mixed before being taken out. Therefore, when the objects to be contained that are intended to be used in a mixed state are contained, it is necessary to take them out into another container and then mix and use them, which is not convenient for the user.

  An object of the present invention is to provide a packaging bag that can be poured out after the contents are sufficiently mixed inside.

  Another object of the present invention is to provide a method of using a packaging bag that allows the contents to be mixed before pouring to be sufficiently mixed inside the packaging bag.

  In order to achieve the above object, the packaging bag of the present invention comprises a resin sheet. The packaging bag includes an accommodating portion capable of accommodating the accommodation item therein, and a mixing member disposed inside the accommodating portion. The mixing member is formed of a substance that is permeable to the contained items and has a structure capable of subdividing the transmitted contained items.

  With this configuration, the stored items are subdivided when the stored items pass through the mixing member. Thereby, the stored items are mixed (stirred), and unevenness of the stored items can be suppressed. Further, when the stored items are a mixture, the effect of mixing can be enhanced, and the convenience of the user can be enhanced.

  In the above structure, the resin sheets are overlapped with each other and the peripheral edge is closed. It further comprises a pouring portion arranged on the peripheral edge and capable of taking out the contained items. The mixing member may be arranged so as to divide the accommodating portion into a portion adjacent to the pouring portion and a portion not adjacent to the pouring portion. By arranging in this way, the stored bag passes through the mixing member by moving the packaging bag up and down or in the rotating direction and shaking it. Thereby, the stored items can be easily mixed, and the convenience of the user can be enhanced.

  In the above-mentioned composition, the mixing member may be arranged adjacent to the pouring part. With such a configuration, when the contained substance is poured out from the pouring portion, it always passes through the mixing member. Therefore, the contained items can be more reliably mixed (stirred). As a result, the user can reduce the number of operations for mixing (stirring), and the convenience of the user can be further enhanced.

  In the above configuration, the resin sheet is a front surface portion that is arranged in front of the housing portion, a rear surface portion that is arranged behind, and a bottom surface portion that is bonded to the lower portion of the front surface portion and the lower portion of the rear surface portion. And the mixing member may be fixed to the front surface portion and the rear surface portion. With this configuration, the packaging bag can be set up and stored. Further, since the bottom portion is provided, the storage amount of the stored items can be increased.

  In the above structure, the mixing member may be a mesh material or a porous body.

  In the above configuration, the contained material may include two or more kinds of substances having fluidity and different properties, and the resin sheet may be formed of a material that suppresses permeation of each of the substances.

  In the method of using the packaging bag having the above-mentioned configuration, the operation of shaking the packaging bag is repeated a plurality of times so that the stored items move across the mixing member from the first storage chamber to the second storage chamber or vice versa. The contents may be mixed. With the packaging bag, the operation of mixing the contained items is simple, and the convenience of the user can be enhanced.

  According to the packaging bag of the present invention, the contents before pouring can be sufficiently mixed inside the packaging bag. As a result, it is possible to improve the convenience of the user.

  Further, the present invention can provide a method of using the packaging bag that allows the contents to be mixed before pouring to be sufficiently mixed inside the packaging bag.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the packaging bag 1 of this embodiment. FIG. 2 is a sectional view taken along line II-II of the packaging bag 1 shown in FIG. Note that “upper”, “lower”, “left”, and “right” are based on the state shown in FIG. Further, "front" means the front side of the paper surface in FIG. 1, and "rear" means the back side of the paper surface in FIG. In the packaging bag 1 shown in FIG. 1, the heat-bonding portion 21 is hatched and the mixing member 43 is hatched.

  The packaging bag 1 is formed by a so-called standing pouch, and includes a bag body 2 and a pouring portion 3. The spout 3 is made of resin and is attached to the top of the bag body 2. The details of the attachment of the spout 3 will be described later.

  The bag body 2 is made of a transparent resin sheet 100 and has a front surface portion 5, a rear surface portion 6 and a bottom surface portion 8. At the peripheral edge of the bag body 2, a heat-bonding portion 21 is formed by heat-bonding the heat-bonding resin layers 17 (see FIG. 2) arranged on the inner surface of the resin sheet 100. An accommodation portion 4 for accommodating the accommodation object S is formed inside the bag body 2 surrounded by the heat-bonding portion 21. The contained material S is a substance that has a fluidity such that it can flow inside the accommodating portion 4 and can be poured out from the pouring portion 3. Although the details will be described later, in the present embodiment, the contained item S is a substance containing liquid soap and air.

  When the front surface portion 5 and the rear surface portion 6 are arranged to face each other, the front surface portion 5 and the rear surface portion 6 are provided with an inclined portion 51 and an inclined portion 61 that are inclined toward the right side toward the upper left side when viewed from the front side. The upper portions of the left and right side ends of the front surface portion 5 and the rear surface portion 6, the inclined portion 51, the inclined portion 61 and the upper end portion are heat-bonded to each other to form the heat-bonded portion 21.

  The bottom surface portion 8 is sandwiched between the lower portion of the front surface portion 5 and the lower portion of the rear surface portion 6 by folding the resin sheet 100 in two. The bottom surface portion 8 is heat-bonded to the lower portion and the lower end portion of the side surface of the front surface portion 5 and the rear surface portion 6 by the heat bonding portion 21. The upper end of the bag body 2 is opened, and after the contents S are stored, they are heat-bonded by the heat-bonding portion 21.

  Further, a plurality of unbonded unbonded parts 9 are provided in the heat bonded parts 21 on the left and right ends of the bottom surface part 8. The unbonded portion 9 can prevent the bottom surface portion 8 from curling due to thermal contraction during the thermal bonding process.

  Here, the resin sheet 100 will be described. FIG. 3 is a cross-sectional view of the resin sheet 100. As shown in FIG. 3, the resin sheet 100 is formed by laminating a base material layer 11, an intermediate layer 15, and a thermoadhesive resin layer 17 in this order from the outside to the inside of the bag body 2. The base material layer 11 and the intermediate layer 15 are bonded via the adhesive layer 14, and the intermediate layer 15 and the thermo-adhesive resin layer 17 are bonded via the adhesive layer 16.

  The base material layer 11 is formed of, for example, a biaxially oriented polypropylene (OPP) film having a thickness of about 9 to 25 μm. As the base material layer 11, for example, a thermoplastic resin such as a uniaxially or biaxially stretched polyester film, polyolefin film, or polyamide film can be used. The printing layer 12 is formed to a thickness of about 1 to 5 μm by the ink arranged at a predetermined position on the base material layer 11. The print layer 12 is formed by, for example, gravure printing.

  The intermediate layer 15 is formed of, for example, a vapor deposition film in which a transparent vapor deposition film 15b is vapor deposited on the lower surface of a transparent resin film 15a having a thickness of about 10 to 25 μm. Thereby, the intermediate layer 15 has a gas barrier property against gases such as water vapor and oxygen due to the transparent vapor deposition film 15b. The transparent resin film 15a is formed of, for example, a polyethylene terephthalate film, a polyester film, a polyamide film, or the like. The transparent vapor deposition film 15b is formed of silica, alumina, or the like.

  The heat adhesive resin layer 17 is formed of, for example, a linear low density polyethylene (LLDPE) film having a thickness of about 25 to 150 μm. The heat-bonding portions 21 (see FIGS. 1 and 2) are formed by heat-bonding the heat-bonding resin layers 17 facing each other. Further, the heat adhesive resin layer 17 may be formed of a low density polyethylene (LDPE) film, a non-stretched polypropylene (CPP) film, or the like.

  The adhesive layers 14 and 16 are made of, for example, an acrylic adhesive. The base material layer 11 and the intermediate layer 15 are adhered to each other by the dry laminating method using the adhesive layer 14, and the intermediate layer 15 and the thermoadhesive resin layer 17 are adhered to each other by the dry laminating method using the adhesive layer 16. The base material layer 11 and the intermediate layer 15 are adhered to each other via the adhesive layer 14 by an extrusion method using an extrusion coater (not shown) or the like, and the intermediate layer 15 and the heat-adhesive resin layer are interposed via the adhesive layer 16. 17 and 17 may be bonded. At this time, the adhesive layer 14 and the adhesive layer 16 are formed of, for example, a polyethylene film or the like.

  Returning to FIG. 1, the pouring unit 3 will be described. The pouring portion 3 is attached to a portion of the thermal bonding portion 21 where the inclined portion 51 and the inclined portion 61 are bonded (hereinafter, referred to as a tilted bonding portion 211). The spout 3 includes a spout body 31 and a lid 32. The spout body 31 is attached to the inclined adhesive portion 211 and fixed to the bag body 2. The lid 32 is detachably attached to the spout body 31.

  The spout body 31 includes an adhesive base 311 and a spout 312. The adhesive base 311 is thermally adhered together when the inclined adhesive portion 211 is thermally adhered. Thereby, the adhesive base 311 is fixed to the inclined adhesive portion 211. The adhesive base 311 has a rib on the top. In the adhesive base 311, the rib is exposed and arranged outside the bag body 2. As a result, the adhesive base portion 311 is positioned on the inclined adhesive portion 211 and the displacement is suppressed.

  The spout 312 is formed integrally with the adhesive base 311. The spout 312 is connected to a portion exposed to the outside of the adhesive base 311, here, a rib. Both the adhesive base 311 and the spout 312 are cylindrical. The space inside the adhesive base 311 communicates with the space inside the spout 312. In the packaging bag 1, the housing portion 4 is communicated with the outside via the spout body 31. As a result, the accommodation section 4 is brought into a state in which the accommodation object S can be ejected to the outside via the ejection section 3. That is, the spout body 31 serves as an opening for taking out the contents S contained in the container 4 of the packaging bag 1.

  The lid 32 has a cylindrical shape with a closed end. The spout 312 is provided with a male screw (not shown) on the outer surface. The inner surface of the lid portion 32 is provided with a female screw (not shown) that is screwed with the male screw. The lid 32 is detachably attached to the spout 312. The pouring part 3 is opened and closed by the attachment and detachment of the lid part 32. Then, by opening and closing the pouring portion 3, the housing portion 4 is opened and closed.

  Next, the details of the housing portion 4 will be described. As shown in FIGS. 1 and 2, the accommodation portion 4 is a space formed inside the bag body 2 and capable of accommodating the accommodation object S. The accommodating portion 4 includes a first accommodating chamber 41, a second accommodating chamber 42, and a mixing member 43.

  The first storage chamber 41 and the second storage chamber 42 are arranged side by side vertically. Then, it is vertically divided by the mixing member 43. As shown in FIGS. 1 and 2, the first storage chamber 41 is adjacent to the pouring portion 3, and the second storage chamber 42 is adjacent to the bottom surface portion 8.

  The mixing member 43 is formed of a material through which the contents S can pass. Here, the mixing member 43 is a non-woven fabric, and when the contents S pass through the mixing member 43, they are finely divided (divided) by the mixing member 43. That is, the contents S are mixed (stirred) by the mixing member 43. The contained item S contained in the packaging bag 1 of the present embodiment is configured to include two or more kinds of different substances having fluidity capable of flowing inside the accommodation section 4.

  Therefore, when passing through the mixing member 43, the substances forming the contained object S are mixed (stirred). The mixing member 43 is in the form of a sheet and is fixed to the front surface portion 5 and the rear surface portion 6 by heat bonding, like the heat bonding portion 21. In the packaging bag 1, the mixing member 43 is bent so that the center in the front-rear direction faces upward, and is attached inside the housing portion 4. The mixing member 43 may be attached to the inside of the accommodating portion 4 in a shape that is bent a plurality of times, a so-called accordion shape. It is possible to widely adopt a configuration that can be reliably fixed inside the housing portion 4.

  The mixing member 43 is not limited to the non-woven fabric, and may be, for example, a porous body such as a sponge, a lattice-like substance such as a knit or a mesh, but is not limited thereto. As the mixing member 43, a wide range of materials can be used, which are formed of a substance that can mix (stir) the contained items S when the contained items S pass through. Further, the mixing member 43 is not limited to a sheet shape as long as it has a configuration capable of partitioning the housing portion 4 into the first housing chamber 41 and the second housing chamber 42.

  The packaging bag 1 according to this embodiment has the above-described configuration. Next, a method of using the packaging bag 1 will be described with reference to the drawings. FIG. 4 is a front view showing an operation of moving the stored item S from the second storage chamber 42 of the packaging bag 1 to the first storage chamber 41. 5: is a front view which shows the operation | movement which moves the content S from the 1st storage chamber 41 of the packaging bag 1 to the 2nd storage chamber 42. As shown in FIG. In FIG. 4 and FIG. 5, the contents S before being mixed are indicated by a rough dot hatch, and the contents S after being mixed are indicated by a fine dot hatch. In addition, the white arrows in the figure show the moving direction of the packaging bag 1 and the moving direction of the contents S in the mixing member 43.

  In the present embodiment, the container S is a mixture of liquid soap and air. It should be noted that the air may be the air that entered when the liquid soap was filled. It may also be filled with an appropriate amount of air to bubble the liquid soap. Furthermore, in order to suppress deterioration such as oxidation, an inert gas such as nitrogen gas or carbon dioxide gas may be filled.

  The liquid soap, which is the contained item S contained in the packaging bag 1, is used, for example, for washing the face, limbs, body and the like. At this time, the user foams the liquid soap and then attaches the foamed liquid soap to the target portion to wash it. In the packaging bag 1 of the present embodiment, liquid soap that has been foamed in advance can be poured out from the pouring portion 3. One of the methods of using the packaging bag 1 of the present embodiment, a method of foaming liquid soap, that is, a method of mixing contained items will be described.

  As described above, the packaging bag 1 is a standing pouch. For example, the packaging bag 1 is stored in an upright state in a storage shelf or the like. Therefore, in the packaging bag 1 of the present embodiment, the liquid soap is stored in the second storage chamber 42 before use. The air is stored in the first storage chamber 41 and the second storage chamber 42.

  As shown in FIG. 4, the user manually holds the side portion of the packaging bag 1 so that the first storage chamber 41 is on the upper side and the second storage chamber 42 is on the lower side. Then, after the user moves his or her hand upwards, the liquid soap moves upward due to inertial force by stopping the hand. At this time, the liquid soap passes through the mixing member 43 together with the air, is mixed (stirred), and moves to the first storage chamber 41. Since liquid soap has a low surface tension, bubbles are generated when liquid soap and air are mixed.

  Next, as shown in FIG. 5, after the user moves his / her hand downward, the liquid soap moves downward due to inertial force by stopping the hand. At this time, the liquid soap passes through the mixing member 43 together with the air, is mixed (stirred), and moves to the second storage chamber 42. Further, the liquid soap is mixed (stirred) with air. As a result, bubbles of the liquid soap become smaller (more fine) as they flow into the second storage chamber 42.

  In this way, when the user moves the hand holding the packaging bag 1 up and down, the contents S inside the packaging bag 1, that is, the liquid soap foams. In the above description, it is assumed that after moving upward, it stops after moving downward, but in the actual use state, after moving upward, it is moved downward immediately, and movement downward is completed. Immediately after that, a reciprocating motion (swing) of moving upward is performed. Also in this case, when the moving direction of the bag body 2 is switched, the moving direction of the bag body 2 and the direction of the inertial force acting on the stored object S are opposite, so that the same effect as when stopped is obtained. It is possible to obtain

  Then, after the liquid soap is sufficiently bubbled, the user can open the lid 32 of the pouring portion 3 and take out the foamed liquid soap from the spout 312. Thereby, after pouring the liquid soap from the packaging bag 1, a tool for foaming is unnecessary, and the labor for foaming can be omitted. Further, the liquid soap and the air are mixed while being accommodated inside the accommodating portion 4 of the packaging bag 1. Therefore, for example, when mixing the liquid soap and the air (the container) for a child or an acquaintance, the user can whip the liquid soap (the container) without touching the liquid soap. From these things, it is possible to improve the convenience for the user by using the packaging bag of the present embodiment.

  In addition, in this embodiment, although the mixture S of liquid soap and air was demonstrated as an example as the content S, it is not limited to this. For example, a substance that has been conventionally used as a liquid, such as a seasoning liquid such as soy sauce or sauce, may be subjected to a process that easily foams, and may be used when foaming and pouring. By doing so, the texture of the seasoning liquid can be changed (for example, softened) by being entangled with the air. Moreover, since the surface area is increased by bubbling, the amount of seasoning liquid used can be suppressed. That is, it is possible to enjoy a new texture and contribute to maintaining health.

  Further, it may be a liquid that is hard to mix between two types, such as a dressing using a seasoning liquid and oil. In the case of such two kinds of liquids, it is possible to mix the liquids and to emulsify them depending on the kind.

  As shown above, as the contained item S, a substance that is used by being poured out after being sufficiently mixed inside the packaging bag 1 can be widely adopted. As the packaging bag 1, a wide variety of packages can be used that can accommodate a substance to be poured out by mixing a plurality of substances or by bubbling a liquid with a gas.

  In the packaging bag 1 of the present embodiment, the contents S are mixed when passing through the mixing member 43. Then, the packaging bag 1 may be provided with a window portion on at least one of the front surface portion 5 and the rear surface portion 6 for confirming a mixed state of the contents S (a foaming state in the case of the above-described liquid soap). preferable. The window portion is made of transparent resin, and the inside of the housing portion 4 can be visually recognized from the outside. As described above, by providing the window portion, the user can easily check the mixed state of the contained items S, and the convenience of the user can be enhanced.

  Then, the user can check the mixed state from the window and can pour the contained article S in a desired mixed state (in the case of the above-mentioned liquid soap, a foaming state) from the pour-out section 3. . Further, for example, when a part of the contained items S is mixed, the uncontained contained items S are accumulated in the accommodation unit 4 below. Utilizing this fact, first, the sufficiently mixed contents S are poured out from the pouring section 3, and then the packaging bag 1 is tilted so that the pouring section 3 is located at the lower side, and the mixing is insufficient. The object S may be poured out. By doing so, it is possible to pour the well-mixed contents S and the non-mixed (not so much) contents S into the same place.

  For example, if the container S is milk added to coffee, both liquid milk and whipped milk can be added to the same coffee, and different tastes can be simultaneously enjoyed. This enhances the convenience of the user. Note that the contents S are not limited to milk for coffee, and substances that use both mixed and unmixed substances can be widely adopted.

<Second Embodiment>
Another example of the packaging bag of the present embodiment will be described with reference to the drawings. FIG. 6 is a front view of the packaging bag 1b according to the present embodiment. The packaging bag 1b shown in FIG. 6 has the same configuration as the packaging bag 1 except that the mixing member 44 is different from the mixing member 43. Therefore, in the packaging bag 1b, substantially the same portions as the packaging bag 1 are denoted by the same reference numerals, and detailed description of the same portions is omitted.

  As shown in FIG. 6, in the packaging bag 1b, the mixing member 44 is arranged so as to diagonally cross the storage portion 4b. Then, in the housing portion 4b, in FIG. 6, the right side of the mixing member 44 is the first housing chamber 41b, and the left side is the second housing chamber 42b. In other words, across the mixing member 44, the pouring part 3 side is the second storage chamber 42b, and the opposite side is the first storage chamber 41b.

  As shown in FIG. 6, in the packaging bag 1b, the lower end portion of the mixing member 44 is arranged apart from the lower end portion of the housing portion 4b. Therefore, in the accommodation portion 4b, the first accommodation chamber 41b and the second accommodation chamber 42b communicate with each other at the lower portion. Like the mixing member 43, the mixing member 44 has a sheet shape, is bent, and is fixed to the front surface portion 5 and the rear surface portion 6. The mixing member 44 has the same characteristics as the mixing member 43, and detailed description thereof will be omitted.

  Next, a method of using the packaging bag 1b according to the present embodiment will be described with reference to the drawings. FIG. 7 is a front view showing an operation of moving the contained item S from the second storage chamber 42b of the packaging bag 1b to the first storage chamber 41b. FIG. 8 is a front view showing an operation of moving the contained item S from the first storage chamber 41b of the packaging bag 1b to the second storage chamber 42b. In FIG. 7 and FIG. 8, the contents S before being mixed are indicated by a coarse dot hatch, and the contents S after being mixed are indicated by a fine dot hatch. Further, the white arrows in the figure show the moving direction of the packaging bag 1 and the moving direction of the contents S in the mixing member 44.

  In the present embodiment, the container S is a mixture of liquid soap and air. It should be noted that the air may be the air that entered when the liquid soap was filled. One of the methods of using the packaging bag 1 of the present embodiment, a method of foaming liquid soap, that is, a method of mixing contained items will be described.

  As described above, in the packaging bag 1b, as in the packaging bag 1, the liquid soap and the air pass through the mixing member 44 by shaking, and the liquid soap and the air are mixed (stirred) to foam. When the user shakes the packaging bag 1b, as shown in FIGS. 4 and 5, it is considered that the packaging bag 1b is linearly reciprocated in the longitudinal direction and shaken. In addition to this, for example, it is also possible to rotate and shake the packaging bag 1b held by the palm by rotating the wrist around the axis. The packaging bag 1b of the present embodiment is used when rotating and shaking. It should be noted that the shaking method (shake direction) may be displayed on the outer surface of the packaging bag 1b.

  First, as shown in FIG. 7, the user holds the side portion of the packaging bag 1b so that the pouring portion 3 is on the upper side. Then, the user shakes the hand to rotate the packaging bag 1b in the clockwise direction (CW in FIG. 7). Due to this rotation, the liquid soap in the container 4b moves to the upper part by centrifugal force. Since the second storage chamber 42b is on the rear side in the moving direction of the first storage chamber 41b, that is, the rear side in the clockwise direction CW, most of the liquid soap moves to the upper portion of the second storage chamber 42b. Then, by stopping the hand, the liquid soap moves in the clockwise direction CW by the inertial force. At this time, the liquid soap passes through the mixing member 44 together with the air, is mixed (stirred), and moves to the first storage chamber 41b side. Since liquid soap has a low surface tension, bubbles are generated when liquid soap and air are mixed.

  Next, as shown in FIG. 8, the user moves his hand counterclockwise (CCW direction in FIG. 8), whereby the liquid soap moves to the upper part of the first storage chamber 41b by the centrifugal force. Then, by stopping the hand, the liquid soap moves in the counterclockwise direction CCW by the inertial force. At this time, the liquid soap passes through the mixing member 44 together with the air, is mixed (stirred), and moves to the second storage chamber 42b. Further, the liquid soap is mixed (stirred) with air. As a result, bubbles of the liquid soap become smaller (more fine) as they flow into the second storage chamber 42b.

  Then, after the liquid soap is sufficiently bubbled, the user can open the lid 32 of the pouring portion 3 and take out the foamed liquid soap from the spout 312. As described above, by using the packaging bag 1, the user can use the whipped liquid soap without soiling his / her hands and without using the whipped device.

  In this way, the user rotates the wrist around the axis, so that the packaging bag 1b is reciprocated in the rotation direction. As a result, the contents S inside the packaging bag 1b, that is, the liquid soap, foams. In the above description, after the movement in the clockwise direction CW and the movement in the counterclockwise direction CCW, the movement is stopped, but in the actual use state, the movement in the clockwise direction CW and the movement in the counterclockwise direction CCW are performed. Are performed continuously.

  As a result, the contained object S inside the accommodating portion 4b is always located above the accommodating portion 4b due to the centrifugal force. By arranging the mixing member 44 in the packaging bag 1b so as to cross the accommodation portion 4b obliquely, the range in which the contained object S passes through the mixing member 44 in one movement can be increased. Thereby, the contained items S can be efficiently mixed (stirred). Regarding the shape and arrangement of the mixing member 44, it is preferable to arrange the mixing member 44 in accordance with the movement of the contents S when the packaging bag 1b is moved. Specifically, it is possible to efficiently mix (stir) by arranging the packaging bag 1b along the radius when moving in the rotation direction and by arranging it as long as possible.

The other features are the same as those in the first embodiment.
<Third Embodiment>
Another example of the packaging bag of the present embodiment will be described with reference to the drawings. FIG. 9 is a front view of the packaging bag 1c according to this embodiment. The packaging bag 1c shown in FIG. 9 has the same configuration as the packaging bag 1 except that the accommodating portion 4c includes the mixing member 45. Therefore, in the packaging bag 1c, substantially the same portions as the packaging bag 1 are denoted by the same reference numerals, and detailed description of the same portions is omitted. The lengths of the inclined portions 51 and 61 of the packaging bag 1c are shorter than those of the inclined portions 51 and 61 of the packaging bag 1, but since the configurations are substantially the same, the same reference numerals are given and detailed description thereof is omitted. To do.

  As shown in FIG. 9, the housing portion 4c of the packaging bag 1c includes a mixing member 45 formed in one space and arranged inside. As shown in FIG. 9, the mixing member 45 is arranged so as to surround a portion of the accommodation portion 4c adjacent to the pouring portion 3. As a result, when the contained object S accommodated in the accommodating portion 4c is poured out from the pouring portion 3, it passes through the mixing member 45. The contents S are mixed (stirred) by the mixing member 45 and then poured out from the pouring unit 3.
