Summary of the Invention

Problems to be Solved by the Invention

[0004] In this type of pouch product, when the amount of the accommodated contents decreases, it may become difficult for the pouch to maintain a self-standing posture. For example, when the pouch bends or falls without maintaining a self-standing posture, the contents may drip from the discharge port onto the placement surface of the pouch product.

[0005] One aspect of this disclosure provides a technique for making it easier for a pouch to maintain a self-standing posture even when the amount of contents decreases in a pouch product.

Means for Solving the Problems

[0006] One aspect of the present disclosure is a pouch comprising a pouch body, a spout, and a cap. The pouch body has a sheet-like first sheet portion and a sheet-like second sheet portion superimposed on the first sheet portion. The pouch body is configured to form a storage space for storing contents between the first sheet portion and the second sheet portion. The spout is cylindrical. The spout is positioned between the first sheet portion and the second sheet portion. The spout forms a discharge port for discharging contents from the storage space. The cap is attached to the spout and is configured to be able to close and open the discharge port. The cap has a contact portion. The contact portion is configured to contact the mounting surface when the pouch is placed on a mounting surface with the spout side of the pouch body facing downwards. The ratio of the diameter of the smallest inclusion circle, which is the circle with the smallest diameter among the circles that enclose the contact portion, to the height of the pouch body from the contact portion along the central axis of the spout is 0.06 or more and 0.6 or less.

[0007] When a pouch with this configuration is used, it becomes easier for the pouch product to maintain an upright posture even when the amount of contents decreases.

[0008] In one aspect of this disclosure, the contact area may be planar. When a pouch with such a configuration is used, it becomes easier for the pouch to maintain an upright position even when the amount of contents in the pouch product decreases.

[0009] In one aspect of this disclosure, the ratio of the diameter of the minimum containing circle to the width of the pouch body along the direction perpendicular to the central axis of the spout may be 0.1 or more and 0.7 or less. When a pouch with such a configuration is used, the pouch product can be made more likely to maintain an upright posture even when the amount of contents decreases.

[0010] In one aspect of this disclosure, the bending stiffness of at least one of the first sheet portion and the second sheet portion is 0.4 gf·cm 2 / cm or more 2.5gf cm 2It may be less than / cm. When a pouch with this configuration is used, the pouch product can be made more likely to maintain an upright posture even when the amount of contents decreases.

[0011] In one aspect of this disclosure, the cap may have a cap body and a lid. The cap body is cylindrical. The cap body is attached to the spout so as to surround the outer circumference of the spout. The lid is connected to the cap body via a hinge. The lid is configured to be displaceable between a closed position that closes the discharge port and an open position that opens the discharge port. Such a configuration can improve the convenience of the pouch.

[0012] One aspect of the present disclosure is a pouch product comprising the aforementioned pouch and contents. The contents are contained within a containment space. The ratio of the diameter of the minimum containing circle to the weight of the contents is 0.07 or more and 1.2 or less. With this configuration, the pouch product can be made more likely to maintain an upright posture even when the amount of contents decreases. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0014] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings.

[0015] [1. Configuration] The pouch product 100 shown in FIG. 1 includes a pouch 1 and a content M.

[0016] The content M is accommodated in the pouch 1. The content M has fluidity. The content M is, for example, a hair cosmetic composition. The hair cosmetic composition refers to a composition applied to hair. The hair cosmetic composition includes, for example, hair cosmetic compositions such as shampoo, treatment, hair mask, etc., decoloring and dyeing hair compositions such as color shampoo and color treatment, and semi-permanent dyeing hair compositions such as hair manicure.

[0017] The pouch 1 is a packaging body for accommodating the content M. The pouch 1 is formed symmetrically about the left and right. The pouch 1 is configured to be self-standing. Specifically, the pouch 1 is configured to be self-standing in both the upright posture shown in FIG. 1 and the inverted posture shown in FIG. 2. The upright posture and the inverted posture will be described in detail later, but the names of the upright posture and the inverted posture do not limit the up and down of the pouch 1 as a product. The pouch 1 includes a pouch body 2, a spout 3, and a cap 4.

[0018] As shown in FIG. 1, the pouch body 2 is a member configured to be able to form an accommodation space R. The accommodation space R is a space for accommodating the content M. The pouch body 2 has a first sheet portion 21, a second sheet portion 22, a third sheet portion 23, and a seal portion 24.

[0019] As shown in Figure 3, the first sheet portion 21, the second sheet portion 22, and the third sheet portion 23 are sheet-like. The first sheet portion 21, the second sheet portion 22, and the third sheet portion 23 are composed of the sheet material 25 shown in Figure 4. The sheet material 25 is a flexible sheet-like member. The bending rigidity of the sheet material 25 is, for example, 0.4 gf·cm. 2 / cm or more 2.5gf cm 2 It is less than or equal to / cm. In this specification, bending stiffness refers to the value measured at 25°C using a 4cm x 4cm test piece of the sheet material in question, with a pure bending tester KES-FB2-S manufactured by Kato Tech Co., Ltd.

[0020] The sheet material 25 has a multilayer structure in which multiple layers are stacked. The sheet material 25 has at least a sealing layer 251 and a barrier layer 252.

[0021] The seal layer 251 is configured to be welded to other seal layers 251 (i.e., to other seal layers 251, or to other parts of the seal layer 251 itself) by at least one of heat and / or pressure. The material of the seal layer 251 is, for example, polyethylene (PE).

[0022] The barrier layer 252 is configured to block gases and liquids. A specific example of a gas is oxygen. The barrier layer 252 may also be configured to block light, for example. The material of the barrier layer 252 may be polyethylene terephthalate (PET), nylon, aluminum, etc.

[0023] As shown in Figure 3, the first sheet portion 21 and the second sheet portion 22 have the same shape and size. The first sheet portion 21 and the second sheet portion 22 are, for example, rectangular. The first sheet portion 21 and the second sheet portion 22 are stacked on top of each other with the sealing layers 251 facing each other. Hereinafter, one of the in-plane directions of the stacked first sheet portion 21 and the second sheet portion 22 will be referred to as the vertical direction D1. Also, one of the in-plane directions of the stacked first sheet portion 21 and the second sheet portion 22 that is perpendicular to the vertical direction D1 will be referred to as the left-right direction D2. When the first sheet portion 21 and the second sheet portion 22 are rectangular, the longitudinal direction of the first sheet portion 21 and the second sheet portion 22 corresponds to the vertical direction D1, and the short direction of the first sheet portion 21 and the second sheet portion 22 corresponds to the left-right direction D2.

[0024] The first sheet portion 21 has a first edge portion 211, a second edge portion 212, a third edge portion 213, and a fourth edge portion 214. The first to fourth edges 211 to 214 constitute the outer edge of the first sheet portion 21. Specifically, they are as follows:

[0025] The first edge portion 211 constitutes one edge of the first sheet portion 21 in the vertical direction D1. The second edge portion 212 constitutes the other edge of the first sheet portion 21 in the vertical direction D1 (i.e., the edge opposite to the first edge portion 211). The third edge portion 213 constitutes one edge of the first sheet portion 21 in the horizontal direction D2. The fourth edge portion 214 constitutes the other edge of the first sheet portion 21 in the horizontal direction D2 (i.e., the edge opposite to the third edge portion 213).

[0026] The second sheet portion 22 has a first edge portion 221, a second edge portion 222, a third edge portion 223, and a fourth edge portion 224. The first to fourth edges 221 to 224 constitute the outer edge of the second sheet portion 22. Specifically, they are as follows:

[0027] The first edge portion 221 constitutes one edge of the second sheet portion 22 in the vertical direction D1. The second edge portion 222 constitutes the other edge of the second sheet portion 22 in the vertical direction D1 (i.e., the edge opposite to the first edge portion 221). The third edge portion 223 constitutes one edge of the second sheet portion 22 in the horizontal direction D2. The fourth edge portion 224 constitutes the other edge of the second sheet portion 22 in the horizontal direction D2 (i.e., the edge opposite to the third edge portion 223).

[0028] With the first sheet portion 21 and the second sheet portion 22 overlapping each other, the first edges 211, 221, the second edges 212, 222, the third edges 213, 223, and the fourth edges 214, 224 face each other. A spout 3 is positioned between the first edges 211, 221. As will be described in detail later, the spout 3 is a cylindrical member.

[0029] The third sheet portion 23 has dimensions in the left-right direction D2 that are equal to those of the first sheet portion 21 and the second sheet portion 22. The third sheet portion 23 is folded along a fold line L extending in the left-right direction D2 such that the sealing layer 251 faces outward. The third sheet portion 23 is positioned between the ends of the first sheet portion 21 and the second sheet portion 22 that are opposite to the spout 3 side (i.e., the ends including the second edges 212 and 222), with the fold line L side facing the spout 3 side.

[0030] As shown in Figures 1 to 3, the seal portion 24 is the portion where the opposing edges 211 to 214 and 221 to 224 of the first sheet portion 21 and the second sheet portion 22 are welded to each other directly or indirectly. The opposing edges 211 to 214 and 221 to 224 of the first sheet portion 21 and the second sheet portion 22 are basically welded to each other directly.

[0031] However, with respect to the first edge 211 of the first sheet portion 21 and the first edge 221 of the second sheet portion 22, in the region where the spout 3 is positioned between them, these first edges 211 and 221 are welded to the spout 3, respectively. In other words, in that region, the first edges 211 and 221 are indirectly welded to each other via the spout 3.

[0032] Furthermore, with respect to the second to fourth edges 212 to 214 of the first sheet portion 21 and the second to fourth edges 222 to 224 of the second sheet portion 22, in the region where the third sheet portion 23 is positioned between them, these second to fourth edges 212 to 214 and 222 to 224 are welded to the third sheet portion 23, respectively. In other words, in that region, the second edges 212 and 222 are welded to each other, the third edges 213 and 223 are welded to each other, and the fourth edges 214 and 224 are welded to each other indirectly via the third sheet portion 23.

[0033] The first sheet portion 21 and the second sheet portion 22 are welded together along their respective outer edges. As shown in Figure 1, the third sheet portion 23 is widened so that the bending angle along the bending curve L increases, thereby increasing the distance between the first sheet portion 21 and the second sheet portion 22. In other words, a storage space R is formed inside the pouch body 2.

[0034] As shown in Figure 3, the spout 3 is a cylindrical member. That is, the spout 3 has a shape in which an internal hole is formed that is continuous from the first surface to the second surface opposite the first surface. The central axis X of the spout 3 is straight. The spout 3 is made of, for example, polypropylene (PP). The spout 3 is positioned between the first sheet portion 21 and the second sheet portion 22 (more specifically, between the first edge portions 211 and 221). As shown in Figure 7, the spout 3 is positioned in the center of the pouch body 2 in the left-right direction D2. The central axis X of the spout 3 coincides with the center line of the pouch body 2. The center line of the pouch body 2 is a straight line that passes through the geometric center of the pouch body 2 and extends in the up-down direction D1. As shown in Figure 3, the spout 3 has a base portion 31 and a tip portion 32.

[0035] As shown in Figure 2, the base portion 31 is a cylindrical part. The internal shape of the base portion 31 in this embodiment, perpendicular to the central axis X, is circular (more specifically, perfectly circular). The external shape of the base portion 31 in this embodiment, perpendicular to the central axis X, is generally rhombic. As shown in Figures 3 and 5, the base portion 31 is positioned between the first sheet portion 21 and the second sheet portion 22 (specifically, between the first edges 211 and 221). The outer circumferential surface of the base portion 31 is welded to the first sheet portion 21 and the second sheet portion 22 (specifically, their first edges 211 and 221) around its entire circumference.

[0036] The tip portion 32 is a cylindrical part that is continuous with the base portion 31. The tip portion 32 in this embodiment is cylindrical. That is, the cross-section of the tip portion 32 in this embodiment perpendicular to the central axis X is circular in both its inner and outer shape (more specifically, perfectly circular). The tip portion 32 extends outward from the pouch body 2. The opening on the tip portion 32 opposite to the base portion 31 side functions as a discharge port 33 for discharging the contents M from the containment space R. That is, the spout 3 forms a discharge port 33. A male screw 321 is formed on the outer circumferential surface of the tip portion 32.

[0037] Cap 4 is attached to spout 3. Cap 4 is made of, for example, polypropylene (PP). The combined weight of spout 3 and cap 4 is heavier than, for example, the weight of pouch body 2.

[0038] The cap 4 is configured to be able to close and open the discharge port 33. The cap 4 has a cap body 41, a lid 42, and a hinge 43. The cap 4 is a so-called hinged cap.

[0039] The cap body 41 is a bottomed cylindrical portion. The cap body 41 has a peripheral wall portion 411 and an end wall portion 412.

[0040] The peripheral wall portion 411 is a cylindrical part. The peripheral wall portion 411 is, for example, cylindrical. As shown in Figure 5, a female thread 4111 is formed on the inner circumferential surface of the peripheral wall portion 411. The female thread 4111 is screwed into the male thread 321 of the tip portion 32. The outer shape of the cross-section perpendicular to the axial direction of the peripheral wall portion 411 is the same in the axial direction of the peripheral wall portion 411. However, the size of this outer shape is larger towards the end wall portion 412. For example, if the peripheral wall portion 411 is cylindrical, the outer diameter of the peripheral wall portion 411 is larger towards the end wall portion 412.

[0041] The end wall portion 412 is a plate-like portion. The end wall portion 412 is, for example, a flat plate. The end wall portion 412 is positioned to cover one opening in the axial direction of the peripheral wall portion 411. The end wall portion 412 is provided with a communication passage 413 that communicates from the front side to the back side of the end wall portion 412. The communication passage 413 in this embodiment includes a through hole 4131 and a communication cylinder 4132. The through hole 4131 is a hole that penetrates the end wall portion 412 in its out-of-plane direction. The communication cylinder 4132 is a cylindrical portion. The communication cylinder 4132 extends from the outer peripheral edge of the through hole 4131 to the side opposite to the peripheral wall portion 411.

[0042] The lid 42 is connected to the cap body 41 via a hinge 43. The lid 42 is configured to be able to close and open the communication passage 413. The lid 42 has a plate portion 421, a frame portion 422, and a cylindrical portion 423.

[0043] The plate portion 421 is a plate-shaped part. In this embodiment, the plate portion 421 is flat. As shown in Figure 8, the plate portion 421 in this embodiment is perfectly circular when viewed from the out-of-plane direction. As shown in Figures 5 and 8, the plate portion 421 is, for example, the same size as the end wall portion 412 or larger than the end wall portion 412 when viewed from the out-of-plane direction.

[0044] As shown in Figures 3 and 5, the frame portion 422 protrudes from the entire circumference of the outer edge of the plate portion 421 toward the cap body 41. The frame portion 422 is connected to the cap body 41 via a hinge 43.

[0045] The cylindrical portion 423 is a cylindrical part. The cylindrical portion 423 protrudes toward the cap body 41 from the portion of the plate portion 421 that faces the communication passage 413. The height of the cylindrical portion 423 from the plate portion 421 is lower than the height of the frame portion 422 from the plate portion 421. The cylindrical portion 423 is configured to be able to close and open the communication passage 413. In this embodiment, the cylindrical portion 423 is configured so that the communication cylinder 4132 fits inside it.

[0046] The cap body 41 is attached to the spout 3 such that the peripheral wall portion 411 surrounds the outer circumference of the tip portion 32. Specifically, the female thread 4111 of the peripheral wall portion 411 is screwed onto the male thread 321 of the tip portion 32. In this state, the end wall portion 412 is in contact with the end face of the tip portion 32. The communication passage 413 communicates with the inner hole of the spout 3. In other words, the discharge port 33 can communicate with the outside of the pouch 1 via the communication passage 413. To put it another way, the discharge port 33 can discharge the contents M from the containment space R to the outside of the pouch 1 via the communication passage 413.

[0047] The lid 42 is configured to be displaceable between a closed position and an open position by a hinge 43.

[0048] As shown in Figures 1 and 5, the closed position is the position where the lid 42 closes the communication passage 413. When the communication passage 413 is closed, the discharge port 33 is also indirectly closed. Therefore, the closed position can also be described as the position where the lid 42 indirectly closes the discharge port 33. In this embodiment, the closed position is the position where the communication cylinder 4132 fits inside the cylindrical portion 423.

[0049] As shown in Figures 3 and 6, the open position is the position where the lid 42 opens the communication passage 413. When the communication passage 413 is open, the discharge port 33 is opened, for example, partially and indirectly. Therefore, the open position can also be described as the position where the lid 42 indirectly opens the discharge port 33. In this embodiment, as shown in Figure 9, the open position is the position where, when viewed along the central axis X of the spout 3, the lid 42 does not overlap the cap body 41.

[0050] As shown in Figure 1, the pouch 1 is able to stand upright on the mounting surface S when the storage space R is formed. The upright position is when the spout 3 side of the pouch body 2 faces upward and the third sheet portion 23 side faces downward (i.e., towards the mounting surface S). The mounting surface S is, for example, a flat surface.

[0051] Furthermore, as shown in Figure 2, the pouch 1 can stand upright on the mounting surface S even in an inverted position. The inverted position is the upside-down position compared to the upright position. That is, in the inverted position, the third sheet portion 23 side of the pouch body 2 faces upward and the spout 3 side faces downward. The pouch 1 can stand upright on the mounting surface S in an inverted position when the lid 42 is in the closed position. The pouch 1 can stand upright on the mounting surface S in an inverted position in both the state in which the storage space R is formed as shown in Figure 2, and the state in which the storage space R is not formed as shown in Figure 7.

[0052] When the pouch 1 is standing upright on the mounting surface S, the top surface of the plate portion 421 of the lid 42 contacts the mounting surface S. The top surface of the plate portion 421 refers to the surface opposite to the cap body 41 side of the plate portion 421. As shown in Figure 5, in this embodiment, since the plate portion 421 is flat, the top surface of the plate portion 421 is planar. Therefore, as shown in Figures 7 and 8, the entire top surface of the plate portion 421 corresponds to the contact portion 424. The contact portion 424 is the part configured to contact the mounting surface S when the pouch 1 is placed on the mounting surface S in an inverted position. Note that in Figure 8, hatching is added to the contact portion 424 for ease of understanding.

[0053] Figure 8 shows the minimum inclusion circle Y. The minimum inclusion circle Y is the circle with the smallest diameter φ among the circles that enclose the contact portion 424. The minimum inclusion circle Y is a perfect circle. To make it easier for the pouch product 100 to maintain an inverted position on the mounting surface S, it is preferable for the diameter φ of the minimum inclusion circle Y to be large. However, if the diameter φ of the minimum inclusion circle Y is too large, the cap 4 (especially the lid 42) may easily get in the way when handling the pouch 1, such as when transporting or displaying the pouch 1.

[0054] Therefore, in the pouch product 100, as shown in Figure 7, the ratio φ / H of the diameter φ [mm] of the minimum containing circle Y to the height H [mm] of the pouch body 2 is designed to be 0.06 or more and 0.6 or less. More specifically, the height H of the pouch body 2 is the height H of the pouch body 2 from the contact portion 424 along the central axis X of the spout 3. This can also be rephrased as the dimension from the contact portion 424 along the central axis X of the spout 3 to the edge of the pouch body 2 on the opposite side from the spout 3. From the viewpoint of making it easier for the pouch 1 to maintain an inverted position on the mounting surface S, it is even more preferable that the above ratio φ / H be 0.15 or more.

[0055] Furthermore, the ratio φ / W of the diameter φ[mm] of the minimum containing circle Y to the width W[mm] of the pouch body 2 is, for example, 0.1 or more and 0.7 or less. More specifically, the width W of the pouch body 2 is the width W of the pouch body 2 along the direction perpendicular to the central axis X of the spout 3. This can also be rephrased as the dimension from one edge to the other edge of the pouch body 2 along the direction perpendicular to the central axis X of the spout 3. From the viewpoint of making it easier for the pouch 1 to maintain an inverted position on the mounting surface S, it is even more preferable that the above ratio φ / W is 0.2 or more.

[0056] Furthermore, the ratio of the diameter φ [mm] of the minimum containing circle Y to the weight [g] of the contents M is, for example, 0.07 or more, more preferably 0.1 or more, and for example, 1.2 or less. The weight of the contents M referred to here is the weight of the contents M of the pouch product 100 before use (i.e., the state in which the contents M has not been dispensed at all).

[0057] Furthermore, making it easier for pouch 1 to maintain an inverted position on the mounting surface S is included in making it easier for pouch 1 to maintain a self-supporting position.

[0058] [2. Effect] In the pouch product 100, the pouch 1 is configured to stand upright on the mounting surface S in both an upright and inverted position. However, when the amount of contents M decreases, the pouch 1 may have difficulty standing upright on the mounting surface S in an upright position. The reason for this is as follows.

[0059] As the amount of contents M decreases, the first sheet portion 21 and the second sheet portion 22 become more prone to bending. As shown in Figure 1, when the pouch 1 is in an upright position, the spout 3 and cap 4 are positioned upward (i.e., relatively away from the mounting surface S). Therefore, if the first sheet portion 21 or the second sheet portion 22 bends, the center of gravity of the pouch 1 is likely to shift. As a result, the pouch body 2 becomes more prone to bending, or the pouch 1 becomes more prone to tipping over, making it difficult for the pouch 1 to maintain an upright position on the mounting surface S. In other words, it becomes difficult for the pouch 1 to maintain a self-supporting position.

[0060] On the other hand, as shown in Figure 2, when pouch 1 is in an inverted position, pouch 1 is more likely to remain upright even if the amount of contents M decreases. This is because, when pouch 1 is in an inverted position, the spout 3 and cap 4 are positioned downwards (i.e., towards the mounting surface S), so even if the first sheet portion 21 or the second sheet portion 22 bends, the center of gravity of pouch 1 is less likely to shift.

[0061] In addition, in pouch 1, the ratio of the diameter φ of the minimum containing circle Y to the height H of the pouch body 2 is between 0.06 and 0.6. When this ratio is between 0.06 and 0.6, pouch 1 is more likely to maintain an inverted position on the mounting surface S, and the cap 4 is less likely to get in the way when handling pouch 1. Here, the diameter φ of the minimum containing circle Y does not change with the amount of contents M. Also, the height H of the pouch body 2 does not change easily with the amount of contents M. For this reason, pouch 1 is more likely to maintain an inverted position on the mounting surface S regardless of the amount of contents M.

[0062] [3. Effects] According to the embodiments described in detail above, the following effects can be obtained.

[0063] (3a) The ratio of the diameter φ of the minimum containing circle Y to the height H of the pouch body 2, φ / H, is 0.06 or more and 0.6 or less. With this configuration, it is possible to suppress the cap 4 from getting in the way when handling the pouch 1. Furthermore, even when the amount of contents M decreases, the pouch 1 can be more easily made to maintain an inverted position on the mounting surface S. Therefore, even when the amount of contents M decreases, the pouch 1 can be more easily made to maintain an upright position.

[0064] (3b) Furthermore, because the pouch 1 can stand upright, it is easier to dispense the contents M from the pouch 1. In the upright position of the pouch 1, the spout 3 is facing downwards, so the user can dispense the contents M from the dispensing port 33 without having to tilt the pouch 1. Therefore, the convenience of the pouch product 100 can be increased.

[0065] (3c) The ratio of the diameter φ of the minimum containing circle Y to the width W of the pouch body 2, φ / W, is, for example, 0.1 or more and 0.7 or less. With this configuration, the cap 4 is less likely to get in the way when handling the pouch 1. Furthermore, even when the amount of contents M decreases, the pouch 1 is more likely to maintain an inverted position on the mounting surface S. Therefore, even when the amount of contents M decreases, the pouch 1 is more likely to maintain an upright position.

[0066] (3d) The ratio of the diameter φ of the minimum containing circle Y to the weight of the contents M is, for example, 0.07 or more and 1.2 or less. With this configuration, even before the contents M are dispensed, the pouch 1 can be made to maintain an inverted position on the mounting surface S more easily. When the contents M are dispensed, the weight of the contents M decreases, which increases the ratio of the diameter φ of the minimum containing circle Y to the weight of the contents M. As a result, the pouch 1 can be made to maintain an inverted position on the mounting surface S more easily. Therefore, even when the amount of contents M decreases, the pouch 1 can be made to maintain an upright position more easily.

[0067] (3e) The bending rigidity of at least one of the first sheet portion 21 and the second sheet portion 22 is, for example, 0.4 gf·cm 2 / cm or more 2.5gf cm 2 It is less than / cm. With this configuration, the first sheet portion 21 and the second sheet portion 22 can be made even more resistant to bending. Therefore, even when the amount of contents M decreases, the pouch 1 can be made even easier to maintain an upright posture (i.e., an upright or inverted posture) on the mounting surface S.

[0068] (3f) The contact portion 424 is planar. With this configuration, when the pouch 1 is in an inverted position and is self-supporting on the mounting surface S, the stability of the pouch 1 on the mounting surface S can be increased. As a result, the pouch 1 can be made to maintain an inverted position on the mounting surface S more easily. Therefore, the pouch 1 can be made to maintain a self-supporting position more easily.

[0069] The (3g) cap 4 comprises a cap body 41 and a lid 42. The lid 42 is configured to be displaceable between a closed position and an open position. With this configuration, by displacing the lid 42, the state in which the discharge port 33 is closed and the state in which the discharge port 33 is open can be changed relatively easily. Therefore, the convenience of the pouch 1 can be improved.

[0070] Furthermore, with the above configuration, the pouch 1 can stand upright not only when the lid 42 is in the closed position, but also when the lid 42 has not returned to the closed position. The state in which the lid 42 has not returned to the closed position means, in other words, that the lid 42 is, for example, indirectly, largely closing the discharge port 33, but not completely closing it. In this embodiment, the state in which the lid 42 has not returned to the closed position can also be described as the state in which the communication cylinder 4132 is not fully fitted inside the cylindrical portion 423. Thus, the ability to stand upright in an inverted position even when the lid 42 has not returned to the closed position enhances the convenience of the pouch 1. And because the pouch 1 can stand upright in an inverted position even when the lid 42 has not returned to the closed position, it becomes easier for the pouch 1 to maintain an inverted position on the mounting surface S.

[0071] (3h) Pouch 1 is configured to stand on its own in both an upright and inverted position. This configuration enhances the convenience of pouch 1. For example, when the amount of contents M is relatively large, the user can place pouch 1 on the mounting surface S in an upright position, and when the amount of contents M decreases, the user can place pouch 1 on the mounting surface S in an inverted position.

[0072] (3i) In this embodiment, the contents M is a hair cosmetic composition. In this case, there is a greater desire to maintain the pouch 1 in an upright position. This is because the operation of dispensing the contents M and applying it to the hair is generally performed in multiple steps. When the pouch 1 is upright, the user can easily grasp the pouch 1, making it easier to dispense the contents M and apply it to the hair. Therefore, when the contents M is a hair cosmetic composition, it is even more useful to adopt the configuration described above and obtain the effects of (3a) to (3h).

[0073] (3j) For example, if pouch 1 bends or falls over without maintaining an upright posture, the contents M may drip from the discharge port 33 onto the mounting surface S. For this reason, if the contents M is a hair cosmetic composition that contains a dye, there is an even greater desire to maintain an upright posture for pouch 1. If the contents M contains a dye, there is a possibility that the mounting surface S will become soiled if the contents M drips from the discharge port 33 onto the mounting surface S. Therefore, if the contents M contains a dye, it is even more useful to adopt the configuration described above and obtain the effects of (3a) to (3h).

[0074] [4. Other Embodiments] While embodiments of this disclosure have been described above, it goes without saying that this disclosure is not limited to the embodiments described above and can take various forms.

[0075] (4a) In the above embodiment, the entire top surface of the plate portion 421 of the lid 42 corresponds to the contact portion 424. However, the contact portion does not necessarily have to be composed of the entire top surface of the plate portion. For example, as shown in Figures 10A to 11B and Figures 11D (a) to 11F (b), a part of the top surface of the plate portions 421A to 421J, 421L to 421N may constitute the contact portions 424A to 424J, 424L to 424N.

[0076] Figures 10A to 11B, Figure 11D(a), Figure 11E(a), and Figure 11F(a) show the cap with the lids 42A to 42J and 42L to 42N in the closed position, viewed from a position opposite the plate portions 421A to 421J and 421L to 421N. The hinge 43 is not shown in these figures. Also, in Figures 10A to 11B, Figure 11D(a), and Figure 11E(a), hatching is added to the contact portions 424A to 424J, 424L, and 424M for ease of understanding. Figure 11D(b) shows the cap with the lid 42L in the closed position, viewed from a direction perpendicular to the axial direction of the cap body 41. Figures 11E(b) and 11F(b) show the cap with the lids 42M and 42N in the closed position, viewed from a direction inclined with respect to the axial direction of the cap body 41 and 41N, and from the top surface side of the lids 42M and 42N.

[0077] When only a portion, not the entire, of the top surfaces of the plate portions 421A~421J and 421L~421N constitute the contact portions 424A~424J and 424L~424N, the area of ​​the contact portions 424A~424J and 424L~424N, i.e., the area in which the lids 42A~42J and 42L~42N can contact the mounting surface S, can be reduced. For this reason, for example, when the pouch is placed upright on a mounting surface S that is wet with liquid such as water, the amount of liquid that can accumulate between the mounting surface S and the contact portions 424A~424J and 424L~424N can be reduced. Consequently, the pouch can be kept cleaner. This is particularly useful, for example, when pouch products are used in wet areas such as washbasins and bathrooms.

[0078] (4b) For example, as shown in Figures 10A to 10E, Figure 10G, and Figures 11D (a) and (b), at least one groove 425A to 425E, 425G, 425L may be formed in the plate portions 421A to 421E, 421G, 421L. The grooves 425A to 425E, 425G, 425L are portions in which the top surface of the plate portions 421A to 421E, 421G, 421L is partially recessed.

[0079] In the example shown in Figure 10A, multiple grooves 425A are formed in the plate portion 421A. Each groove 425A extends in a straight line. Each groove 425A is formed continuously from one end to the other of the plate portion 421A. The multiple grooves 425A are arranged parallel to each other with some space between them. The bottom surface of each groove 425A is planar. The area on the top surface of the plate portion 421A where no grooves 425A are formed, that is, the area that protrudes relative to the bottom of the grooves 425A, corresponds to the contact portion 424A. The contact portion 424A is planar.

[0080] The examples shown in Figures 10B and 10C have generally the same configuration as the example shown in Figure 10A. However, in the example shown in Figure 10B, each groove 425B extends in a wavy shape rather than a straight line. In the example shown in Figure 10C, each groove 425C extends in a zigzag shape rather than a straight line.

[0081] The examples shown in Figures 10D and 10E have generally the same configuration as the example shown in Figure 10A. However, in the examples shown in Figures 10D and 10E, the multiple grooves 425D and 425E intersect each other at the center of the top surface of the plate portions 421D and 421E.

[0082] The example shown in Figure 10G has a configuration that is generally the same as the example shown in Figure 10A. However, in the example shown in Figure 10G, the multiple grooves 425G intersect with each other so that they form a grid pattern overall.

[0083] In the examples shown in Figures 11D(a) and (b), multiple grooves 425L are formed in the plate portion 421L. Each groove 425L extends in a straight line. The cross-sectional shape of each groove 425L perpendicular to the direction of extension is U-shaped, concave towards its bottom. In other words, the bottom surface of each groove 425L is curved. Each groove 425L is formed continuously from one end to the other of the plate portion 421L. Multiple grooves 425L are arranged parallel to each other with some space between them.

[0084] Furthermore, in the examples shown in Figures 11D(a) and (b), at least the region on the top surface of the plate portion 421L that is sandwiched by the groove portion 425L has a U-shaped cross-sectional shape perpendicular to the extension direction of the groove portion 425L, bulging outwards from the bottom side of the groove portion 425L. The region on the top surface of the plate portion 421L where the groove portion 425L is not formed, and which includes a ridge line, corresponds to the contact portion 424L. At least a part of the contact portion 424L is curved.

[0085] As mentioned above, in the examples shown in Figures 10A to 10E, Figure 10G, and Figures 11D(a) and (b), the grooves 425A to 425E, 425G, and 425L are formed continuously from end to end of the plate portions 421A to 421E, 421G, and 421L. With such a configuration, for example, if liquid adheres to the plate portions 421A to 421E, 421G, and 421L, the grooves 425A to 425E, 425G, and 425L can easily guide the liquid to the outside of the plate portions 421A to 421E, 421G, and 421L. Therefore, the effect described in (4a) above can be obtained more easily.

[0086] Furthermore, when grooves are formed in the plate portion, the number of grooves is not particularly limited. For example, there may be one groove or multiple grooves (for example, two or three or more).

[0087] (4c) For example, as shown in Figures 10F, 10H, 11A, 11B, and (a) and (b) of Figure 11E, at least one protrusion 426F, 426H, 426J, 426M may be formed on the plate portion 421F, 421H to 421J, 421M. The protrusion 426F, 426H to 426J, 426M is a portion of the top surface of the plate portion 421F, 421H to 421J, 421M that protrudes in part.

[0088] In the example shown in Figure 10F, multiple protrusions 426F are formed on the plate portion 421F. Each protrusion 426F extends in a straight line. Each protrusion 426F is formed continuously from end to end of the plate portion 421F. The multiple protrusions 426F intersect each other at the center of the top surface of the plate portion 421F. The leading edges of the multiple protrusions 426F correspond to the contact portion 424F. The leading edge is the surface at the tip in the direction of projection. The contact portion 424F is planar.

[0089] The example shown in Figure 10H has a configuration that is generally the same as the example shown in Figure 10F. However, in the example shown in Figure 10H, the multiple protrusions 426H intersect with each other so that they form a grid pattern overall.

[0090] In the example shown in Figure 11A, a plurality of protrusions 426I are formed on the plate portion 421I. Each protrusion 426I extends in an arc shape along a virtual circle surrounding the center of the plate portion 421I. Each protrusion 426I is located on the outer periphery of the plate portion 421I. The plurality of protrusions 426I are spaced apart from each other in the circumferential direction. The tip surfaces of the plurality of protrusions 426I correspond to the contact portion 424I. The contact portion 424I is planar.

[0091] In the example shown in Figure 11B, multiple protrusions 426J are formed on the plate portion 421J. Each protrusion 426J is a columnar portion. Specifically, each protrusion 426J is cylindrical. The multiple protrusions 426J are spaced apart from each other. The multiple protrusions 426J are evenly distributed across the entire top surface of the plate portion 421J, for example. The tip surfaces of the multiple protrusions 426J correspond to the contact portion 424J. The contact portion 424J is planar.

[0092] As an example similar to Figure 11B, multiple hemispherical protrusions may be formed on the plate portion at intervals from each other. In this case as well, the tip surfaces of the multiple protrusions correspond to the contact area. This contact area is spherical, not planar.

[0093] In the examples shown in Figures 11E(a) and (b), in addition to the multiple protrusions 426M, multiple recesses 427 are formed in the plate portion 421M. Each recess 427 is a portion of the top surface of the plate portion 421M that is partially recessed. The surface of each recess 427, that is, the portion of the top surface of the plate portion 421M that is included in the recess 427, is generally spherical and recessed toward the cap body 41. Similarly, the surface of each protrusion 426M, that is, the portion of the top surface of the plate portion 421M that is included in the protrusion 426M, is generally spherical and bulges toward the opposite side from the cap body 41. The multiple recesses 427 and the multiple protrusions 426M are arranged alternately, like a checkerboard pattern. The region on the top surface of the plate portion 421M that includes the vertices of the multiple protrusions 426M corresponds to the contact portion 424M.

[0094] Furthermore, if protrusions are formed on the plate portion, the number of protrusions is not particularly limited. For example, there may be one protrusion or multiple protrusions (for example, two or three or more).

[0095] (4d) In the above embodiment, the contact portion 424 is planar, but the shape of the contact portion is not particularly limited. For example, as shown in Figures 11D (a) and (b), and Figures 11E (a) and (b), at least a portion of the contact portions 424L and 424M may be curved. Also, for example, as shown in Figures 11F (a) and (b), at least a portion of the contact portion 424N may be linear.

[0096] In the examples shown in Figure 11F(a) and (b), the lid 42N has plate portion 421N and frame portion 422N instead of the plate portion 421 and frame portion 422 described above.

[0097] The plate portion 421N has an outer periphery portion 4211 and an inner periphery portion 4212. Both the outer periphery portion 4211 and the inner periphery portion 4212 constitute the top surface of the plate portion 421N. The outer periphery portion 4211 is the radially outer portion of the plate portion 421N when viewed from the opposite side of the cap body 41N (i.e., as shown in Figure 11F(a)). The outer periphery portion 4211 is annular. The inner periphery portion 4212 is the radially inner portion of the plate portion 421N when viewed from the opposite side of the cap body 41N. The inner periphery portion 4212 is surrounded by the outer periphery portion 4211.

[0098] The top surface of plate section 421N is pleated. A pleated shape is one in which a V-shaped band-like portion that protrudes outward and a V-shaped band-like portion that is recessed inward are arranged alternately. On the top surface of plate section 421N, multiple ridges and valleys of the pleats extend radially from the center of plate section 421N.

[0099] In the region of the outer periphery 4211 on the top surface of the plate portion 421N, multiple edges are arranged on a single virtual plane. In Figure 11F(a), for ease of understanding, the multiple edges included in the outer periphery 4211 are shown as thick lines. The multiple edges included in the outer periphery 4211 correspond to the contact portion 424N.

[0100] In the region of the top surface of the plate portion 421N that is included in the inner circumference portion 4212, the multiple edges are arranged on a single virtual conical surface whose apex faces toward the cap body 41N.

[0101] As shown in Figure 11F(b), for example, the outer surface of the frame portion 422N may also be pleated. The multiple ridges and valleys on the outer surface of the frame portion 422N may be continuous with, for example, the multiple ridges and valleys on the top surface of the plate portion 421N. Also, for example, the outer surface of the cap body 41N may also be pleated.

[0102] (4e) The contact portion does not have to be composed of, for example, a part or all of the top surface of the plate portion of the lid. For example, as shown in Figures 11C(a) and (b), the lid 42K may further have a plurality of legs 428. Figure 11C(a) is a view of the cap with the lid 42K in the closed position, viewed from a position opposite the plate portion 421. In Figure 11C(a), the hinge 43 is not shown. Also, in Figure 11C(a), hatching is added to the contact portion 424K for ease of understanding. Figure 11C(b) is a view of the cap with the lid 42K in the closed position, viewed from a direction perpendicular to the axial direction of the cap body 41.

[0103] In the examples shown in Figures 11C(a) and (b), each leg portion 428 extends across both the top surface of the plate portion 421 and the outer circumferential surface of the frame portion 422, protruding from both. Each leg portion 428 is generally cylindrical in shape. Each leg portion 428 protrudes in a direction away from the center of the plate portion 421 and away from the frame portion 422. The tip surface of each leg portion 428 is generally spherical, bulging outward from the lid 42K. A portion of the tip surface of each leg portion 428 corresponds to the contact portion 424K.

[0104] In the examples shown in Figures 11C(a) and (b), when the inverted pouch is supported on the mounting surface S, the multiple legs 428 can form a gap between the mounting surface S and the plate portion 421. Therefore, for example, if a liquid such as water adheres to the plate portion 421, it can be made easier to dry the plate portion 421. Consequently, the pouch can be kept even cleaner.

[0105] (4f) In the lid 42 of the above embodiment, the plate portion 421 is perfectly circular when viewed from the out-of-plane direction. However, the shape of the plate portion when viewed from the out-of-plane direction is not particularly limited.

[0106] For example, Figures 12A to 12E show a view of the cap with the lid in the closed position, viewed from a position opposite the plate portions 421O to 421S. As shown in Figure 12A, for example, the plate portion 421O may be elliptical when viewed from the out-of-plane direction.

[0107] Furthermore, as shown in Figure 12B, for example, the plate portion 421P may have a polygonal shape, such as a hexagon, where all interior angles are less than 180°, when viewed from the out-of-plane direction of the plate portion 421P.

[0108] Furthermore, as shown in Figure 12C, for example, the plate portion 421Q may have a polygonal shape, such as a star shape, where some of the interior angles exceed 180° when viewed from the out-of-plane direction of the plate portion 421Q.

[0109] For example, as shown in Figure 12D, the plate portion 421R may have a shape that resembles a flower when viewed from the out-of-plane direction of the plate portion 421R. The shape that resembles a flower has a central portion containing the center of the plate portion 421R, and a plurality of extended portions extending radially outward from the central portion. The plurality of extended portions resemble petals.

[0110] For example, as shown in Figure 12E, the plate portion 421S may be heart-shaped when viewed from the out-of-plane direction.

[0111] In the examples shown in Figures 12A to 12E, the top surfaces of the plate portions 421O to 421S are all flat. Therefore, the entire top surface corresponds to the contact portions 424O to 424S.

[0112] (4g) In the cap 4 of the above embodiment, the cap body 41 is a bottomed cylindrical portion. The cap body 41 has a peripheral wall portion 411 and an end wall portion 412. However, the cap body does not necessarily have to have an end wall portion. In other words, the cap body may be a simple cylindrical portion. In this case, when the cap body is attached to the spout 3, the lid may be configured to be able to directly close and open the discharge port 33.

[0113] (4h) The cap 4 in the above embodiment is a so-called hinged cap. However, the cap does not necessarily have to be a hinged cap.

[0114] For example, the cap may be a cylindrical member with a bottom. The cap may be attached to the spout 3 so as to cover the outside of the spout 3 from the discharge port 33 side. When the cap is attached to the spout 3, the discharge port 33 is closed. If the inner surface of such a cap has a female thread that screws onto the male thread 321 of the spout 3, the cap is also called a screw cap.

[0115] For example, the cap may also be a member having a columnar portion. The columnar portion is a columnar part. The columnar portion is configured to fit onto the tip portion 32 of the spout 3. When the columnar portion is fitted onto the tip portion 32, the discharge port 33 is closed. Such a cap is also called a press-fit cap.

[0116] (4i) In the above embodiment, the pouch 1 is configured to be self-supporting on the mounting surface S in both an upright and inverted position. However, the pouch does not necessarily have to be configured to be self-supporting in an upright position. In this case, for example, the pouch body does not have to have a third sheet portion.

[0117] (4j) The functions of one component in the above embodiment may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, some parts of the configuration of the above embodiment may be omitted. Also, at least some parts of the configuration of the above embodiment may be added to, replaced with, etc., the configuration of other above embodiments.

[0118] (4k) This disclosure can be implemented in various forms, including the aforementioned pouch 1, a pouch product 100 that uses the pouch 1 as a component, and a method for dispensing the contents M.
