Description

[Technical Field]

[0001] The present disclosure relates to a spouted pouch that is filled with a liquid drug. [Background technology]

[0002] Conventionally, products in which liquid agents such as disinfectants and detergents are filled in plastic bottles have been sold. In recent years, from the perspective of reducing plastic use, pouches filled with liquid agents for refilling the bottles (so-called refill pouches) have been sold. In recent years, large refill pouches filled with multiple doses (enough for multiple bottles) have become mainstream in terms of cost performance.

[0003] Such large pouches have a problem in that the amount of liquid medicine is large and heavy, making it difficult for users to control the force of the liquid medicine flowing out when refilling the bottle. This has led to problems such as the liquid medicine coming out too quickly and spilling out of the bottle during refilling.

[0004] In this regard, Patent Document 1 discloses a structure in which a mechanism for restricting the flow path is provided at the outlet of the pouch, and the force of the liquid agent is controlled by pressing the outlet with a finger.

[0005] However, in the configuration of Patent Document 1, it cannot be said that all users will recognize the intention behind providing a mechanism to restrict the flow path, nor can it be said that users will intuitively understand the shape and function of the mechanism, etc. For this reason, there are cases where users do not press the mechanism with their fingers or press it in an inappropriate way, resulting in the failure to obtain the desired effect.

[0006] Furthermore, Patent Document 2 discloses a configuration in which an operation position indicator is provided as a mark indicating the position where the user should press with their finger when discharging the liquid medicine. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2017-65747 [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-118195 Summary of the Invention [Problem to be solved by the invention]

[0008] Incidentally, Patent Document 2 provides a check valve to prevent backflow of the liquid agent, and a circular operating position indicator to indicate the position where the check valve flap should be pressed. According to the inventors' investigations, when a circular operating position indicator is provided as in Patent Document 2, users often press the indicator with the "tip" of their finger. With a configuration in which the flap is pressed as in Patent Document 2, the check valve can be operated without any problems even when pressed with the tip of a finger.

[0009] On the other hand, according to the study by the inventors of the present application, in the configuration of Patent Document 1, if the user presses the mechanism that restricts the flow path with the "tip" of their finger, the flow of the liquid may not be stopped sufficiently. In other words, in the configuration of Patent Document 1, the effect of stopping the liquid varies greatly depending on how the user presses with their finger. [Means for solving the problem]

[0010] In view of the above circumstances, an object of the present invention is to provide a spouted pouch having a flow path control mechanism that allows a user to intuitively understand where and how to press.

[0011] In one aspect of the present disclosure, a spout-equipped pouch can be provided, the spout-equipped pouch including a surface film that forms the front side of a storage section that stores a liquid agent, a back surface film that forms the back side of the storage section, and a spout that forms a flow path through which the liquid agent stored in the storage section flows out to the outside. The spout-equipped pouch has a pair of flow path-restricting seal portions provided on both sides of an extension line of the central axis of the spout, and a guidance indicator portion that guides a user's hand so that the user presses the flow path-restricting portion between the pair of flow path-restricting seal portions with the pads of their fingers is provided on at least one of the front and back surfaces of the storage section.

[0012] According to this configuration, when the user wants to cause the liquid agent contained in the storage section to flow out of the spout, the user's hand is guided by the guidance display section, allowing the user to press the flow path restricting section with the pad of the finger, thereby enabling the user to reliably press the flow path restricting section to adjust the flow rate of the liquid agent or reliably stop the outflow of the liquid agent.

[0013] The front and rear films may be opaque, in which case the guidance display unit may be formed by a printed portion on the outer surface of the front or rear film.

[0014] In other words, since an opaque container cannot visually confirm the liquid inside, it is difficult for the user to determine how to press with their fingers. In such a container, if a guide display is provided by printing, it is possible to easily guide the user's hand. The front film and the back film do not have to be entirely opaque, and only a portion of them may be transparent.

[0015] The guidance display portion may be a mark having an elongated shape in a direction perpendicular to the central axis of the spout. By providing a elongated mark on the container portion, the user is guided to press the relevant portion with the "pad" of the finger rather than the "tip" of the finger. This can reliably stop the liquid medication from leaking out.

[0016] The guidance display unit may display the outline of the flow path restricted by the pair of flow path restricting seal units. This allows the user to grasp the outline of the flow path restricting seal units before pressing the flow path restricting units, and thus intuitively grasp which part to press and how to press to stop the outflow of the liquid medication. This allows the user's hand to be appropriately guided.

[0017] The spout may be provided on only one side of the storage unit in the width direction. In this case, the storage unit has an asymmetrical shape in the width direction, and the direction in which the storage unit is held varies depending on the user's dominant hand. For example, a right-handed person would hold the side of the storage unit without the spout (the right side as viewed from the front of the storage unit) with their right hand, whereas a left-handed person would hold the side of the storage unit without the spout (the left side as viewed from the front of the storage unit) with their left hand. For this reason, if the guidance display is displayed on only one of the front and back sides of the storage unit, it would be very difficult for the dominant hand to see. Therefore, by providing the guidance display on both the front and back sides of the storage unit, the user's hand can be guided regardless of the dominant hand.

[0018] The guidance display portion may be, for example, an illustration of a finger. This configuration allows the user to easily understand the location where the user should press the finger and the orientation of the finger when pressing. [Effects of the Invention]

[0019] As described above, a guidance display section is provided to guide the user's hand so that they press the flow path restricting section with the pad of their finger, making it easier for the user to intuitively understand where and how to press when adjusting the flow rate of the liquid agent or stopping the outflow.

[Figure 3]FIG. 3 is a view corresponding to FIG. 1 according to the first modification of the embodiment. [Figure 4] FIG. 4 is a view corresponding to FIG. 1 according to the second modification of the embodiment. [Figure 5] FIG. 5 is a view corresponding to FIG. 1 according to the third modification of the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0022] FIG. 1 is a side view of a spouted pouch 1 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the spouted pouch 1. The spouted pouch 1 includes a storage section 2 that stores various liquid agents, and a spout 3 that forms a flow path through which the liquid agent stored in the storage section 2 flows out to the outside. The liquid agent stored in the storage section 2 is not particularly limited, but may be, for example, a disinfectant, bactericide, insecticide, repellent, herbicide, agricultural chemical, various detergents, seasonings, or other liquid agents. The liquid agent only needs to be fluid, and may have a higher viscosity than water. The liquid agent can be stored in the storage section 2 by filling the storage section 2 with the liquid agent using a filling device (not shown).

[0023] The spouted pouch 1 may be a so-called refill pouch that can be used to refill a plastic bottle (not shown) made of hard resin and can be used multiple times. When the spouted pouch 1 is a refill pouch, it may be a large pouch that can accommodate the liquid medicine equivalent to multiple plastic bottles. The spouted pouch 1 may also be a disposable pouch that can be used up in one go. The spouted pouch 1 may also be a spraying pouch that sprays a liquid medicine from the spout. In this case, the spout may be configured so that a sprayer (such as a shower) can be connected to the tip of the spout.

[0024] 1 and 2, in the description of this embodiment, the width direction and front and back directions of the spouted pouch 1 are defined. The definition of the directions of the spouted pouch 1 is for the convenience of description and does not limit the direction of the spouted pouch 1 when in use or when stored, and the spouted pouch 1 may be used or stored in any direction.

[0025] The storage section 2 has a vertical dimension longer than its width dimension, giving it an overall vertically elongated shape. The storage section 2 is made up of three components: a surface film 20 that forms the front side of the storage section 2, a back film 21 that forms the back side of the storage section 2, and a bottom film 22 that forms the bottom of the storage section 2. The surface film 20, back film 21, and bottom film 22 are made of flexible resin films. Therefore, the storage section 2 as a whole becomes a flexible packaging body that is easily deformed. The resin material that makes up the film is not particularly limited, but examples include polyethylene-based resins and polypropylene-based resins.

[0026] Further, examples of the film include a laminated film in which multiple resin films are laminated. The laminated film may be, for example, a film having a base film serving as a substrate and a heat-sealable fusion film laminated on the base film. The laminated film may also be a film having a layer composed of metal foil or a film having a metal-vapor-deposited layer. By providing a metal foil layer or a metal-vapor-deposited layer, all or part of the surface film 20, back film 21, and bottom film 22 can be made opaque.

[0027] A printing layer can be provided on the surface film 20, the back film 21, and the bottom film 22. For example, an opaque portion can be formed by printing at least a portion of the surface film 20, the back film 21, and the bottom film 22 by gravure printing, flexographic printing, inkjet printing, or the like. The surface film 20, the back film 21, and the bottom film 22 may all be opaque. If the surface film 20, the back film 21, and the bottom film 22 are all opaque, the liquid agent cannot be seen from the outside. Alternatively, some of the surface film 20, the back film 21, and the bottom film 22 may be transparent and the other portions may be opaque. In this case, the liquid agent can be seen from the transparent portions. Alternatively, the surface film 20 and the back film 21 may be opaque, and the bottom film 22 may be transparent.

[0028] A front-side inclined edge 20a extending obliquely is formed at the upper part of one widthwise side of the front film 20. A back-side inclined edge 21a extending obliquely in a similar manner is formed at the upper part of one widthwise side of the back film 21. The inclination angles of the front-side inclined edge 20a and the back-side inclined edge 21a are set to be approximately equal. A spout 3 is provided at the part where the front-side inclined edge 20a and the back-side inclined edge 21a are formed.

[0029] The peripheral edge of the surface film 20 is provided with a surface-side fused portion 20b, which serves as a heat-sealing area for the back film 21 and the bottom film 22. The peripheral edge of the back film 21 is provided with a back-side fused portion 21b, which serves as a heat-sealing area for the surface film 20 and the bottom film 22. The peripheral edge of the bottom film 22 is provided with a bottom-side fused portion 22b, which serves as a heat-sealing area for the surface film 20 and the back film 21. In FIG. 2 , the rough shapes of the surface-side fused portion 20b, the back-side fused portion 21b, and the bottom-side fused portion 22b are indicated by dashed lines. The surface-side fused portion 20b, the back-side fused portion 21b, and the bottom-side fused portion 22b are heated to a predetermined temperature or higher to adhere to each other, thereby obtaining a storage compartment 2 with a sealed peripheral edge. The surface-side fused portion 20b, the back-side fused portion 21b, and the bottom-side fused portion 22b are made of the above-mentioned fused film.

[0030] Because the storage section 2 has the bottom film 22, the dimension of the storage section 2 in the front-to-back direction when it contains a liquid medicine increases as it goes downward. This makes the spouted pouch 1 a so-called standing pouch, so it can stand on its own when placed on a horizontal surface. The bottom film 22 can also be omitted.

[0031] The spout 3 is provided on only one widthwise side of the storage section 2. This gives the storage section 2 an asymmetric shape in the widthwise direction. The spout 3 is made of a hard resin material and has a base 30 that is welded to the front film 20 and the back film 21, and a tubular section 31 that is integrally molded with the base 30. The resin material that makes up the spout 3 is a resin material that can be fused to the front-side fused section 20b and the back-side fused section 21b, which improves the fusion properties between the spout 3 and the front film 20 and the back film 21. Because the spout 3 is made of a hard resin material, even if a user presses the spout 3 with their finger, the spout 3 itself hardly deforms, and it is not possible to adjust the flow rate by deforming the spout 3.

[0032] The base 30 of the spout 3 has a flat shape that extends along the front-side inclined edge 20a and the back-side inclined edge 21a. The outer surface located on the front side of the base 30 is heat-sealed to the front-side fused portion 20b of the front film 20 in the vicinity of the front-side inclined edge 20a, and the outer surface located on the back side of the base 30 is heat-sealed to the back-side fused portion 21b of the back film 21 in the vicinity of the back-side inclined edge 21a. This seals the attachment portion of the spout 3.

[0033] The tubular portion 31 of the spout 3 is provided so as to protrude obliquely upward from the base portion 30 toward the outside of the storage portion 2. The central axis of the tubular portion 31 (shown by the dashed-dotted line A in FIG. 1 ) is inclined in a direction opposite to the inclination direction of the front-side inclined edge portion 20 a and the back-side inclined edge portion 21 a in side view. Specifically, the central axis A of the tubular portion 31 and the extending direction of the front-side inclined edge portion 20 a and the back-side inclined edge portion 21 a are perpendicular to each other. The tip of the tubular portion 31 is open, and this opening at the tip serves as an outlet (not shown) for the liquid medication. When the spout-equipped pouch 1 is stored, a cap 32 is removably attached to the tubular portion 31, and the outlet is closed by the cap 32.

[0034] In this embodiment, the spout 3 is made of a hard resin material and cannot be deformed by the user, so the spout-equipped pouch 1 has a flow path restricting section 40 for adjusting the flow rate of the liquid and stopping the outflow of the liquid.

[0035] The flow path restricting portion 40 is formed between a pair of flow path restricting seal portions 42a, 42b. The flow path restricting seal portions 42a, 42b are formed by closely contacting the surface film 20 and the back film 21 and heat welding them into a predetermined shape. As shown in FIG. 1 , in a side view, the flow path restricting seal portions 42a, 42b are provided on both sides of an extension line of the central axis A of the spout 3 into the storage portion 2, and are formed continuous with the seal on the periphery of the storage portion 2. The pair of flow path restricting seal portions 42a, 42b are formed so as to protrude toward the inside of the pouch beyond the position of the base portion 30 of the spout 3 in a direction parallel to the central axis A of the spout 3. Note that the surface film 20 and the back film 21 are not welded in the portion between the pair of flow path restricting seal portions 42a, 42b. As a result, a flow path through which the liquid agent can flow from the storage portion 2 toward the spout 3 is formed between the pair of flow path restricting seal portions 42a, 42b. The pair of flow path restricting seal portions 42a, 42b have a constriction portion where the distance between the flow path restricting seal portions 42a, 42b (the width of the flow path) is the shortest, and this portion is designated as the flow path restricting portion 40. If the flow path is extremely narrow in the flow path restricting portion 40, the outflow speed of the liquid agent will decrease. Therefore, it is preferable that the width of the flow path in the flow path restricting portion 40 (the shortest distance between the flow path restricting seal portions 42a, 42b) is larger than the inner diameter of the tubular portion 31 of the spout 3. From the viewpoint of ease of flow rate adjustment (described below) by the flow path restricting portion 40, the width of the flow path in the flow path restricting portion 40 is preferably 30 mm or less, and more preferably 20 mm or less. Furthermore, if the distance between the pouch inner end of the base portion 30 of the spout 3 and the constriction portion (flow path restricting portion 40) is too close in the direction parallel to the central axis A of the spout 3, it will be difficult to hold the flow path restricting portion 40 (described below). Therefore, this distance is preferably 10 mm or more, and more preferably 20 mm or more.

[0036] The pair of flow path restricting seal portions 42a, 42b formed as described above form a flow path on the upstream side of the spout 3, and also provide a flow path restricting portion 40 that restricts the width of the flow path. Note that a throttle portion need not be provided in the flow path (the distance between the flow path restricting seal portions 42a, 42b may be constant). In this case, any position between the flow path restricting seal portions 42a, 42b can be used as the flow path restricting portion 40.

[0037] A flow path is formed inside the base 30 of the spout 3. The flow path formed inside the base 30 communicates with a flow path restricting section 40 via an inlet 30a that opens on the surface of the base 30 facing the inside of the storage section 2. The flow path restricting section 40 communicates with the inside of the storage section 2. The flow path formed inside the base 30 also communicates with the inside of the tubular section 31. Therefore, the liquid agent stored in the storage section 2 passes through the flow path restricting section 40, flows from the inlet 30a into the flow path inside the base 30, flows through the flow path, then flows through the flow path inside the tubular section 31, and flows out from the outlet.

[0038] Because the surface film 20 and the back film 21 are flexible, the flow path limiting section 40 is also flexible and can be easily deformed by simply pressing it with a user's finger. When a user presses the flow path limiting section 40 in the front-to-back direction, the inner surfaces of the surface film 20 and the back film 21 in the flow path limiting section 40 move closer to each other. Because the flow path limiting section 40 is located near the inlet 30a of the spout 3 and upstream of the inlet 30a, the narrower the gap between the inner surfaces of the surface film 20 and the back film 21 in the flow path limiting section 40, the more difficult it is for the liquid to flow into the inlet 30a of the spout 3. The gap between the inner surfaces of the surface film 20 and the back film 21 in the flow path limiting section 40 can be easily changed by the amount of force applied by the user's finger. This makes it possible to adjust the flow rate of the liquid flowing out of the spout 3.

[0039] Furthermore, when the user presses the flow path restricting section 40 in the front-to-back direction until the inner surfaces of the surface film 20 and the back film 21 in the flow path restricting section 40 are completely in contact with each other, the flow path leading to the inlet 30a of the spout 3 is closed. To ensure that the inner surfaces of the surface film 20 and the back film 21 in the flow path restricting section 40 are completely in contact with each other, it is preferable for the user to press the flow path restricting section 40 with the pads of their fingers. If one were to press both sides of the flow path restricting section 40 with the tips of their fingers, the thin tips of their fingers would result in pressing with a "point," and only a portion of the flow path restricting section 40 would be pressed. As a result, a gap would likely form between the inner surfaces of the surface film 20 and the back film 21 in the flow path restricting section 40. Therefore, it would be difficult to completely close the flow path leading to the inlet 30a of the spout 3, and there is a risk that the liquid agent would not be stopped.

[0040] In contrast to this, in this embodiment, guidance indicators 41 that guide the user's hand so that the user presses the flow path restricting section 40 with the pad of the finger, i.e., in a "line" (or "plane"), are provided on both the front and back surfaces of the storage section 2. The guidance indicators 41 are intended to indicate the position, shape, and size of the flow path restricting section 40, and the user can press the flow path restricting section 40 appropriately by pressing the guidance indicators 41 even if they do not know the position of the flow path restricting section 40.

[0041] The guidance display unit 41 may be provided on only one of the front film 20 and the back film 21. This is because the user can press the flow path restricting unit 40 even if the guidance display unit 41 is provided on only one of the front film 20 and the back film 21. The form of the guidance display unit 41 is not particularly limited, and as an example, the guidance display unit 41 may be configured as a portion printed on the outer surface of the front film 20 or the back film 21 (the outer surface of the storage section 2). When the guidance display unit 41 is provided on both the front film 20 and the back film 21, the guidance display unit 41 can be configured as a portion printed on the outer surfaces of both the front film 20 and the back film 21.

[0042] In the example shown in FIG. 1, guidance display section 41 is a mark that is elongated in a direction perpendicular to central axis A of spout 3. The width of guidance display section 41 in the direction perpendicular to central axis A of spout 3 is preferably at least 1.5 times, and more preferably at least 2 times, the width in the direction parallel to central axis A. By providing an elongated mark in container section 2 in this way, the user's hand is guided to press the relevant part with the "pad" of the finger, rather than the "tip" of the finger. This makes it possible to reliably stop the liquid medication from leaking out.

[0043] The guidance indicator 41 is preferably provided so as to straddle (overlap) the pair of flow path restricting seal portions 42a, 42b in a side view. That is, the width of the guidance indicator 41 in a direction perpendicular to the central axis A of the spout 3 is configured to be slightly larger than the width of the flow path at that portion (the width of the flow path restricting portion 40). This guides the user's hand to straddle the pair of flow path restricting seal portions 42a, 42b and press it with the pads of their fingers, thereby completely blocking the flow path between the flow path restricting seal portions 42a, 42b (the flow path restricting portion 40). This more reliably stops the liquid medication from leaking out.

[0044] The guidance display unit 41 may be configured by changing the color from the surrounding area of ​​the guidance display unit 41, by applying a pattern different from the surrounding area of ​​the guidance display unit 41, by only a frame line, or by using letters or symbols. The guidance display unit 41 is not limited to a visual display, and may be configured to display tactilely by, for example, embossing. The guidance display unit 41 may be rectangular, oval, elliptical, or a free-form curved figure.

[0045] FIG. 3 shows a spout-equipped pouch 1 according to a first modified example of the embodiment. In this first modified example, the guidance indicator 41A is an illustration of a finger. The illustration is drawn so that the user can press the flow path restricting section 40 with the pad of the finger by placing their finger along the illustration of the finger. This illustration is a printed part. An illustration of a thumb may be drawn as the guidance indicator 41A on the front side of the storage section 2, and an illustration of an index finger or middle finger may be drawn as the guidance indicator 41A on the back side.

[0046] FIG. 4 shows a spout-equipped pouch 1 according to a second modification of the embodiment. In this second modification, the guidance indicator 42 displays the outline of the flow path restricted by the pair of flow path restricting seal portions 42a, 42b. That is, the width of the flow path restricted by the pair of flow path restricting seal portions 42a, 42b is set to be significantly narrower than the width of the storage portion 2. The shape, position, and size of the flow path restricted by the pair of flow path restricting seal portions 42a, 42b are difficult to discern from the outside and are difficult to understand at a glance. By configuring the guidance indicator 42 to display the outline of the flow path restricted by the pair of flow path restricting seal portions 42a, 42b as in the second modification, the user's hand can be guided to press the flow path restricting portion 40 with the pad of the finger. The guidance indicator 42 may be configured as a line following the outline of the flow path restricted by the pair of flow path restricting seal portions 42a, 42b, or may display the outline by using different colors or patterns inside and outside the flow path restricted by the pair of flow path restricting seal portions 42a, 42b. Furthermore, the guidance display section 42 is not limited to a visual display, and may be configured to display tactilely by, for example, embossing.

[0047] Fig. 5 shows a spout-equipped pouch 1 according to a third modification of the embodiment. This third modification has guidance indicator 41 consisting of a mark elongated in a direction perpendicular to central axis A of spout 3, and guidance indicator 42 displaying the outline of the flow path restricted by a pair of flow path restricting seal portions 42a, 42b. In this way, a plurality of guidance indicators 41, 42 may be provided in one storage section 2. In the third modification, guidance indicator 41A (shown in Fig. 3) consisting of an illustration of a finger as in the second modification may be provided instead of guidance indicator 41.

[0048] (Effects of the embodiment) As described above, according to this embodiment, since guidance display unit 41 is provided in storage unit 2 as shown in Fig. 1, when the user causes the liquid agent stored in storage unit 2 to flow out from spout 3 and inject it into a bottle (not shown), the user's hand is guided by guidance display unit 41. This makes it possible to press flow path restricting unit 40 with the pads of the fingers, thereby enabling the user to reliably press flow path restricting unit 40 to adjust the flow rate of the liquid agent or reliably stop the outflow of the liquid agent.

[0049] In this embodiment, the container 2 is opaque, and since the user cannot see the liquid inside the container 2, it is difficult to determine where and how to press with the fingers when adjusting the flow rate or stopping the liquid medication. In this container 2, the guide display 41 is provided by printing, so that the user's hand can be easily guided.

[0050] 1 and 5, by making guidance display portion 41 a mark that is elongated in a direction perpendicular to central axis A of spout 3, the user's hand is guided to press flow path restricting portion 40 with the "pad" of the finger, rather than the "tip" of the finger. This makes it possible to reliably stop the outflow of the liquid medication.

[0051] 4 and 5, in the case of guidance display unit 42 that displays the outline of the flow path restricted by a pair of flow path restricting seal portions 42a, 42b, the user can grasp the outline of the pair of flow path restricting seal portions 42a, 42b before pressing flow path restricting unit 40, and can therefore intuitively grasp which part to press and how to press to stop the outflow of the liquid medication. This allows the user's hand to be appropriately guided.

[0052] Furthermore, in this embodiment, the spout 3 is provided only on one side of the storage unit 2 in the width direction, so that the storage unit 2 has an asymmetrical shape in the width direction. If the user is right-handed, the user will hold the side of the storage unit 2 without the spout 3 (the right side as viewed from the front of the storage unit 2) with their right hand, but conversely, if the user is left-handed, the user will hold the side of the storage unit 2 without the spout 3 (the left side as viewed from the front of the storage unit 2) with their left hand. For this reason, if guidance indicators 41, 41A, and 42 were displayed on only one of the front and back surfaces of the storage unit 2, they would be very difficult to see depending on the dominant hand. Therefore, by providing guidance indicators 41, 41A, and 42 on both the front and back surfaces of the storage unit 2, the user's hand can be guided to the appropriate position regardless of dominant hand.

[0053] The above-described embodiment is merely illustrative in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. For example, the number of components constituting the storage section 2 is not limited to three, but may be two, four or more. [Industrial Applicability]

[0054] As described above, the spouted pouch according to the present invention can be used as, for example, a refill pouch. [Explanation of symbols]
