Summary of the Invention

Problems to be Solved by the Invention

[0004] In this type of pouch product, when the amount of the contents decreases, it may become difficult for the pouch to maintain a self-standing posture. When it becomes difficult for the pouch to maintain a self-standing posture, the operability of the pouch may decrease, and it may become difficult to discharge the contents.

[0005] Therefore, the inventor has considered a method of discharging the contents by laying the pouch down on a placement surface and pressing it against the placement surface. According to such a method, it is possible to easily maintain the operability of the pouch regardless of the amount of the contents. However, as a result of the inventor's detailed examination, it has been found that the contents may drip from the discharge port onto the placement surface when the pouch is laid down on the placement surface.

[0006] One aspect of the present disclosure provides a technique for making it difficult for the contents to drip onto a placement surface in a pouch product.

Means for Solving the Problems

[0007] One aspect of the present disclosure is a pouch comprising a storage section, a cylindrical section, and a protective section. The storage section has a sheet-like first sheet section and a sheet-like second sheet section superimposed on the first sheet section. The storage section is configured to form a storage space for storing contents between the first sheet section and the second sheet section. The cylindrical section is a cylindrical portion positioned between the first sheet section and the second sheet section. The cylindrical section also forms a discharge port for discharging contents from the storage space. The protective section is a portion extending from the first sheet section beyond the discharge port. The protective section is sheet-like. The protective section has a continuous section and an extended section. The continuous section is continuous with the first sheet section. The extended section extends outward beyond the outer edge of the storage section and faces the discharge port.

[0008] When a pouch with this configuration is used, the contents of the pouch product are less likely to drip onto the surface on which it is placed.

[0009] In one aspect of this disclosure, the protective portion may further have an opposing portion. The opposing portion is adjacent to the extended portion and faces the first sheet portion. When such a configuration is used in a pouch, the contents of the pouch product can be made even less likely to drip onto the surface on which it is placed.

[0010] In one aspect of this disclosure, the continuous portion may be positioned on the opposite side from the extended portion, with the opposing portion in between. When a pouch with such a configuration is used, the contents of the pouch product can be made even less likely to drip onto the surface on which it is placed.

[0011] In one aspect of this disclosure, the ratio of the distance from the outer edge to the end edge of the extended portion to the distance from the outer edge to the opening surface of the discharge port in the axial direction of the cylindrical portion may be 2 or more and 5 or less. When a pouch with such a configuration is used, the contents of the pouch product can be made even less likely to drip onto the surface on which it is placed.

[0012] In one aspect of this disclosure, the ratio of the dimension of the extended portion to the dimension of the opening surface of the discharge port in a direction perpendicular to the axial direction of the cylindrical portion may be 3 or more and 5 or less. When a pouch with such a configuration is used, the contents of the pouch product can be made even less likely to drip onto the surface on which it is placed.

[0013] One aspect of the present disclosure is a pouch product comprising the aforementioned pouch and contents. The contents are contained in a containment space. The contents are a hair dye composition. With such a configuration, the contents can be more effectively prevented from dripping onto the surface on which the pouch product is placed.

Mode for Carrying Out the Invention

[0015] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings.

[0016] [1. First Embodiment] [1-1. Configuration of Pouch Product] The pouch product 100A shown in FIG. 1 includes a pouch 1A and a content M.

[0017] The content M is contained in the pouch 1A. The content M has fluidity. The viscosity of the content M at 25°C is preferably 7000 mPa·s or more and 40000 mPa·s or less.

[0018] In the present embodiment, the content M is a hair dye composition. The hair dye composition refers to a composition containing a dye and configured to be able to dye hair. The hair dye composition includes, for example, a non-permanent hair dye composition such as a color shampoo or a color treatment, and a semi-permanent hair dye composition such as hair manicure.

[0019] The pouch 1A is a package for containing the content M. The pouch 1A is formed symmetrically. The pouch 1A is configured to be self-standing. In the following description and the drawings, the directions such as up, down, left, and right mean the respective directions when the pouch 1A in a self-standing state on the horizontal placement surface S is viewed from the side of the first body portion 21 (that is, viewed as in FIG. 4) unless otherwise specified. As shown in FIG. 1, the pouch 1A has a pouch body 2, a spout 3, a cap 4, a protective sheet 5A, and an adhesive member 6.

[0020] The pouch body 2 is a member configured to be able to form a storage space R. The storage space R is a space for containing the content M. The pouch body 2 has a first body portion 21, a second body portion 22, a bottom portion 23, and a seal portion 24.

[0021] As shown in Figure 2, the first body portion 21, the second body portion 22, and the bottom portion 23 are sheet-like. The first body portion 21, the second body portion 22, and the bottom portion 23 are made of the sheet material 25 shown in Figure 3. The sheet material 25 is a flexible sheet-like member. The sheet material 25 has a multilayer structure in which multiple layers are stacked. The sheet material 25 has at least a seal layer 251 and a barrier layer 252.

[0022] 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).

[0023] 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.

[0024] As shown in Figure 2, the first body portion 21 and the second body portion 22 have the same shape and size. The first body portion 21 and the second body portion 22 are, for example, rectangular in shape. The first body portion 21 and the second body portion 22 are stacked on top of each other with the sealing layers 251 facing each other.

[0025] The bottom portion 23 has the same length in the left-right direction as the first body portion 21 and the second body portion 22. The bottom portion 23 is folded along a fold line F that extends in the left-right direction, such that the sealing layer 251 is on the outside. The bottom portion 23 is positioned between the lower part of the first body portion 21 and the lower part of the second body portion 22, with the fold line F side facing upward.

[0026] As shown in Figures 1 and 2, the seal portion 24 is the portion where the opposing edges of the first body portion 21 and the second body portion 22 are welded to each other directly or indirectly. The edge of the first body portion 21 is the portion that constitutes the outer edge of the first body portion 21. The edge of the second body portion 22 is the portion that constitutes the outer edge of the second body portion 22.

[0027] The opposing edges of the first body section 21 and the second body section 22 are basically directly welded to each other. However, in the region where the bottom section 23 is located between the first body section 21 and the second body section 22, the edges of the first body section 21 and the edges of the second body section 22 are welded to the bottom section 23. In other words, in that region, the opposing edges of the first body section 21 and the second body section 22 are indirectly welded to each other via the bottom section 23.

[0028] Furthermore, as will be described later, a spout 3 is positioned between the first body portion 21 and the second body portion 22, on the side opposite to the bottom portion 23. In the region where the spout 3 is positioned, the edges of the first body portion 21 and the second body portion 22 are welded to the spout 3. That is, in this region, the opposing edges of the first body portion 21 and the second body portion 22 are indirectly welded to each other via the spout 3. The edges of the first body portion 21 and the second body portion 22 are welded along their entire circumference along their respective outer edges.

[0029] As shown in Figure 1, the gap between the first body 21 and the second body 22 is increased by widening the bottom 23 so that the bending angle in the fold curve F is larger. That is, a storage space R is formed inside the pouch body 2. The pouch 1A is able to stand on its own on the mounting surface S when the storage space R is formed. The pouch 1A is able to stand on its own on the mounting surface S with the spout 3 side facing upwards and the bottom 23 side facing downwards (i.e., towards the mounting surface S).

[0030] As shown in Figure 2, the spout 3 is a cylindrical member. That is, the spout 3 has a shape in which a continuous inner hole is formed from the top surface to the bottom surface of the spout 3. The central axis X of the spout 3 is straight. The spout 3 is made of, for example, polypropylene (PP). The spout 3 is located between the first body portion 21 and the second body portion 22. The spout 3 is located on the side opposite to the bottom portion 23 of the pouch body 2. As shown in Figure 6, the spout 3 is located in the center of the pouch body 2 in the left-right direction. When the pouch 1A is standing upright on the mounting surface S, the axial direction of the spout 3 coincides with the vertical direction. The axial direction of the spout 3 is the direction parallel to the central axis X of the spout 3. The spout 3 has a base portion 31 and a tip portion 32.

[0031] As shown in Figures 2 and 7, 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. The base portion 31 is positioned between the first body portion 21 and the second body portion 22. The outer circumferential surface of the base portion 31 is welded to the first body portion 21 and the second body portion 22 around its entire circumference.

[0032] 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 perpendicular to the central axis X of the tip portion 32 in this embodiment is circular in both its inner and outer shape (more specifically, perfectly circular). The tip portion 32 extends beyond the upper edge 20 of the pouch body 2. As shown in Figure 6, the upper edge 20 of the pouch body 2 is the edge of the pouch body 2 opposite to the bottom portion 23 (i.e., the upper side). The upper edge 20 of the pouch body 2 corresponds to a part of the outer edge of the pouch body 2. As shown in Figure 7, the opening of the tip portion 32 opposite to the base portion 31 functions as a discharge port 33 for discharging the contents M from the containment space R. The spout 3 forms the discharge port 33. A male screw 321 is formed on the outer circumferential surface of the tip portion 32.

[0033] As shown in Figures 2 and 7, the cap 4 is a bottomed cylindrical member. The cap 4 is made of, for example, polypropylene (PP). The cap 4 is configured to be detachably attached to the tip 32 so as to cover the tip 32 from the discharge port 33 side. Specifically, a female thread 41 is formed on the inner circumferential surface of the cap 4. The cap 4 is attached to the tip 32 by screwing the female thread 41 into the male thread 321 of the tip 32. The cap 4 is a so-called screw cap. When the cap 4 is attached to the tip 32, the cap 4 closes the discharge port 33.

[0034] Returning to Figure 1, the protective sheet 5A is a sheet-like component. The protective sheet 5A is, for example, rectangular in shape. The protective sheet 5A is flexible. As shown in Figure 7, the protective sheet 5A extends from the first body portion 21 beyond the discharge port 33. The protective sheet 5A has a continuous portion 51, an opposing portion 52, and an extended portion 53.

[0035] The continuous portion 51 is a part that is continuous with the first body portion 21. Specifically, the continuous portion 51 is continuous with the first body portion 21 via the adhesive member 6. That is, the continuous portion 51 is a part that faces the first body portion 21 and has the adhesive member 6 placed between it and the first body portion 21. The adhesive member 6 is configured to bond two parts (in this case, the first body portion 21 and the continuous portion 51) that are positioned on either side of it. The adhesive member 6 may be, for example, double-sided tape or a layer formed of adhesive.

[0036] The opposing portion 52 is the part that faces the first body portion 21. Unlike the continuous portion 51, no adhesive member 6 is placed between the opposing portion 52 and the first body portion 21. For example, a gap is provided between the opposing portion 52 and the first body portion 21.

[0037] As shown in Figure 5, the extended portion 53 is the part that extends outward from the outer edge of the pouch body 2. Specifically, the extended portion 53 extends above the upper edge 20 of the pouch body 2. As shown in Figures 6 and 7, the extended portion 53 faces the discharge port 33.

[0038] The continuous section 51, the opposing section 52, and the extending section 53 are arranged in this order from bottom to top. That is, the continuous section 51 is located on the opposite side of the extending section 53, with the opposing section 52 in between. The opposing section 52 is adjacent to the continuous section 51. The opposing section 52 is adjacent to the extending section 53 on the opposite side of the continuous section 51.

[0039] As shown in Figure 6, in the axial direction of the spout 3, the ratio L2 / L1 of the length of the extension portion 53 to the length L1 of the tip portion 32 is preferably 2 or more. For example, the ratio L2 / L1 may be 2 or more and 5 or less. The length L1 of the tip portion 32 is the dimension from the upper edge 20 of the pouch body 2 to the opening surface of the discharge port 33. In this embodiment, the length L1 of the tip portion 32 is the dimension from the upper edge 20 of the pouch body 2 to the edge of the tip portion 32 on the side opposite to the pouch body 2 (i.e., the upper side). The length L2 of the extension portion 53 is the dimension from the upper edge 20 of the pouch body 2 to the end edge 531 of the extension portion 53. The end edge 531 of the extension portion 53 is the edge of the extension portion 53 on the side opposite to the pouch body 2 (i.e., the upper side). When calculating the above ratio L2 / L1, the length L2 of the extended portion 53 is the maximum length L2 of the extended portion 53 in the range Y that overlaps with the discharge port 33 in a direction perpendicular to the axial direction of the spout 3. The maximum length L2 of the extended portion 53 is the maximum value of the length L2 of the extended portion 53. In this embodiment, the length L2 of the extended portion 53 is constant in the direction perpendicular to the axial direction of the spout 3.

[0040] In a direction perpendicular to the axial direction of the spout 3, the ratio W2 / W1 of the width W2 of the extension portion 53 to the opening width W1 of the discharge port 33 is preferably 3 or more. For example, the ratio W2 / W1 may be 3 or more and 5 or less. The opening width W1 of the discharge port 33 is the dimension of the opening surface of the discharge port 33. In other words, the opening width W1 of the discharge port 33 is the inner dimension of the portion of the tip portion 32 that forms the discharge port 33. If the tip portion 32 is cylindrical, the inner diameter of the tip portion 32 corresponds to the inner dimension of the tip portion 32. The width W2 of the extension portion 53 is the dimension from one end to the other of the extension portion 53. When calculating the above ratio W2 / W1, the width W2 of the extension portion 53 used is the width W2 of the extension portion 53 at the same height as the opening surface of the discharge port 33 in the axial direction of the spout 3. In Figure 6, for ease of understanding, a dashed line Z is shown representing the same height as the opening surface of the outlet 33 in the axial direction of the spout 3.

[0041] For example, in the direction perpendicular to the axial direction of the spout 3, the width W2 of the extension portion 53 is the same as or smaller than the width W3 of the pouch body 2. Specifically, in the direction perpendicular to the axial direction of the spout 3, the maximum width W2 of the extension portion 53 is smaller than the maximum width W3 of the pouch body 2. The maximum width W3 of the pouch body 2 is the maximum value of the width W3 of the pouch body 2. The width W3 of the pouch body 2 is the dimension from one end to the other of the pouch body 2. In this embodiment, the width W2 of the extension portion 53 and the width W3 of the pouch body 2 are both constant in the axial direction of the spout 3.

[0042] [1-2. Method of dispensing contents] Methods for dispensing the contents M in pouch product 100A include a gripping-type dispensing method and a pressing-type dispensing method.

[0043] In the grip-type dispensing method, the user removes the cap 4 from the pouch product 100A, which is standing upright on the mounting surface S, as shown in Figure 1. The user may also remove the cap 4 while the pouch product 100A is lifted from the mounting surface S, for example. Once the cap 4 is removed, the dispensing port 33 is exposed, as shown in Figure 6. Next, the user tilts the pouch product 100A so that the dispensing port 33 faces downwards. Then, the user presses the pouch body 2 from both sides (for example, by gripping the pouch body 2). As a result, the contents M are dispensed from the dispensing port 33.

[0044] In the press-type dispensing method, the user lays the pouch product 100A on its side on the mounting surface S, as shown in Figure 8. Specifically, the user lays the pouch product 100A on its side on the mounting surface S so that the first body portion 21 and the protective sheet 5A are in contact with the mounting surface S. Next, the user removes the cap 4. The user may, for example, lay the pouch product 100A on its side after removing the cap 4. With the cap 4 removed, the user presses the pouch body 2 against the mounting surface S. If the user wants to dispense the contents M onto their hand, the user inserts their hand (e.g., fingers) between the spout 3 and the protective sheet 5A and presses the pouch body 2 against the mounting surface S. As the pouch body 2 is pressed against the mounting surface S, the contents M are dispensed from the dispensing port 33.

[0045] For ease of understanding, in Figure 8, hatching is added to the contents M discharged from the outlet 33. The same applies to Figure 9.

[0046] [1-3. Effect] When the amount of contents M decreases, the pouch product 100A may have difficulty maintaining an upright position. This is because the less contents M there are, the more likely the pouch body 2 is to bend or tip over. In a grip-type dispensing method, if the pouch product 100A has difficulty maintaining an upright position, the operability of the pouch product 100A may decrease. Specifically, the user may have difficulty lifting the pouch product 100A from the mounting surface S. As a result, it may become difficult to dispense the contents M.

[0047] On the other hand, in the press-type dispensing method, the posture of the pouch product 100A, which is laid on its side on the mounting surface S, does not change significantly depending on the amount of contents M. Regardless of the amount of contents M, the contents M are dispensed from the dispensing port 33 when the user presses the pouch body 2 against the mounting surface S. In other words, the operability of the pouch product 100A is easily maintained regardless of the amount of contents M. For example, if the amount of contents M is small, the user can press the pouch body 2 against the mounting surface S with their hand and slide their hand down to the dispensing port 33 (i.e., squeeze the pouch body 2). This makes it easier to ensure a sufficient amount of contents M is dispensed.

[0048] However, in the press-type dispensing method, the pouch product 100A must be lying on its side on the mounting surface S with the cap 4 removed, that is, with the dispensing port 33 exposed. Therefore, it is possible that the contents M may drip from the dispensing port 33 onto the mounting surface S.

[0049] Therefore, the pouch 1A is composed of a protective sheet 5A. The protective sheet 5A extends from the first body 21 beyond the discharge port 33. When a press-type discharge method is used, the pouch product 100A is laid on its side so that the first body 21 and the protective sheet 5A are in contact with the mounting surface S. Therefore, as shown in Figure 9, even if the contents M drip from the discharge port 33, the contents M are more likely to fall onto the protective sheet 5A rather than onto the mounting surface S. In other words, the contents M are less likely to drip onto the mounting surface S.

[0050] [1-4. Effects] According to the first embodiment described in detail above, the following effects can be obtained.

[0051] (1a) In the pouch product 100A, the pouch 1A includes a protective sheet 5A. The protective sheet 5A has a continuous portion 51 and an extended portion 53.

[0052] With this configuration, even if the contents M drip from the discharge port 33 when the pouch product 100A is laid on its side on the mounting surface S, the contents M can be more easily dropped onto the protective sheet 5A rather than onto the mounting surface S. Therefore, it is possible to prevent the contents M from dripping onto the mounting surface S.

[0053] (1b) In this embodiment, the contents M is a hair dye composition. In this case, the user dispenses the contents M onto their hand, for example, and applies the contents M to their hair. If this operation is repeated multiple times, when the user dispenses the contents M again, there is often contents M that were not applied to the hair adhering to the user's hand. For this reason, with a grip-type dispensing method, it is difficult for the user to lift the pouch body 2 from the mounting surface S or to press the pouch body 2 from both sides (for example, it is difficult to grip the pouch body 2). This is because the contents M adhering to the user's hand makes the pouch body 2 slippery. Consequently, when contents M is adhering to the user's hand, it becomes difficult to dispense the contents M with a grip-type dispensing method.

[0054] In contrast, with the press-type dispensing method, even if the contents M adhere to the user's hands, the ease with which the pouch body 2 can be pressed onto the mounting surface S does not change significantly. That is, even if the contents M adhere to the user's hands, the contents M is easily dispensed. Therefore, if the contents M is a hair dye composition, the user may prefer to use the press-type dispensing method over the grip-type dispensing method. For this reason, it is even more useful for the pouch 1A to be composed of a protective sheet 5A so that the effect described in (1a) above can be achieved.

[0055] (1c) Furthermore, when the contents M is a hair dye composition, the discharge port 33 is likely to remain exposed for a long period of time. This is because the operation of dispensing the contents M from the discharge port 33 and applying it to the hair is generally performed in multiple steps. When the discharge port 33 is likely to remain exposed for a long period of time, the likelihood of the contents M dripping from the discharge port 33 increases. For this reason, when the contents M is a hair dye composition, it is even more useful for the pouch 1A to include a protective sheet 5A so that the effect described in (1a) above can be achieved.

[0056] (1d) In the pouch product 100A, the protective sheet 5A further has an opposing portion 52. With this configuration, the user can insert their hand not only between the discharge port 33 and the extended portion 53, but also between the discharge port 33 and the opposing portion 52. In this state, the user can press the pouch body 2 against the mounting surface S, making it easier to dispense the contents M onto the user's hand. Consequently, spillage of the contents M from the user's hand can be suppressed. Therefore, the contents M are less likely to drip onto the mounting surface S.

[0057] (1e) The continuous portion 51 is positioned on the opposite side of the extending portion 53, with the opposing portion 52 in between. With this configuration, for example, compared to a configuration in which the continuous portion 51 is positioned on both sides of the opposing portion 52, the user can more easily insert their hand between the outlet 33 and the opposing portion 52. Therefore, the effect of (1d) above can be more easily obtained. Note that the configuration in which the continuous portion 51 is positioned on both sides of the opposing portion 52 can also be described as a configuration in which the continuous portion 51 has two parts positioned on either side of the opposing portion 52 when viewed from the axial direction of the spout 3.

[0058] (1f) For example, if the contents M drip down onto the extended portion 53, the user may attempt to make the pouch product 100A stand upright on the mounting surface S while the contents M remain attached to the extended portion 53. In this case, the contents M may travel along the protective sheet 5A from the extended portion 53 to the opposing portion 52 due to gravity. However, with the configuration in which the continuous portion 51 is positioned on the opposite side of the extended portion 53 with the opposing portion 52 in between, the movement of the contents M below the continuous portion 51 is restricted by the continuous portion 51. As a result, the contents M are more likely to remain near the boundary between the continuous portion 51 and the opposing portion 52. Therefore, it is possible to make it even less likely for the contents M to drip onto the mounting surface S.

[0059] (1g) From the viewpoint of making it even less likely for the contents M to drip onto the mounting surface S, it is preferable that the length L2 of the axial extension portion 53 of the spout 3 be as long as possible. However, if this length L2 is too long, the extension portion 53 tends to get in the way when handling the pouch product 100A, such as when transporting or displaying the pouch product 100A.

[0060] Therefore, in the axial direction of the spout 3, the ratio L2 / L1 of the length of the extension portion 53 to the length L1 of the tip portion 32 is designed to be, for example, 2 or more and 5 or less. With this configuration, it is possible to further prevent the contents M from dripping onto the mounting surface S, while suppressing the extension portion 53 from getting in the way when handling the pouch product 100A.

[0061] (1h) The width W2 of the extended portion 53 in the direction perpendicular to the axial direction of the spout 3 is also preferable as it is larger from the viewpoint of making it less likely for the contents M to drip onto the mounting surface S. However, if this width W2 becomes too large, the extended portion 53 tends to get in the way when handling the pouch product 100A.

[0062] Therefore, in the direction perpendicular to the axial direction of the spout 3, the ratio W2 of the width W2 of the extended portion 53 to the opening width W1 of the discharge port 33 is designed to be, for example, 3 or more and 5 or less. With this configuration, it is possible to further prevent the contents M from dripping onto the mounting surface S, while suppressing the extended portion 53 from getting in the way when handling the pouch product 100A.

[0063] (1i) In a direction perpendicular to the axial direction of the spout 3, the width W2 of the extended portion 53 is, for example, the same as or smaller than the width W3 of the pouch body 2. With this configuration, the contents M are less likely to drip onto the mounting surface S, and the extension portion 53 is less likely to get in the way when handling the pouch product 100A.

[0064] (1j) The viscosity of the contents M at 25°C is, for example, 7000 mPa·s or more and 40000 mPa·s or less. With this configuration, in a press-type dispensing method, it is possible to maintain the ease with which the user can press the pouch body 2 onto the mounting surface S, while making it even less likely for the contents M to drip from the dispensing port 33 when no external force is applied to the pouch body 2.

[0065] [1-5. Correspondence] In the first embodiment, the pouch body 2 corresponds to an example of a storage section. The first body section 21 corresponds to an example of a first sheet. The second body section 22 corresponds to an example of a second sheet section. The protective sheet 5A corresponds to an example of a protective section.

[0066] In the drawing, the side with the first body portion 21 of the pouch product 100A is shown as the front of the pouch product 100A. However, the front of the pouch product 100A is not particularly limited, and for example, the side with the second body portion 22 of the pouch product 100A may be the front of the pouch product 100A.

[0067] [2. Second Embodiment] [2-1. Composition of Pouch Products] The second embodiment has the same basic configuration as the first embodiment, so the differences will be explained below. Note that the same reference numerals as in the first embodiment indicate the same components, and refer to the preceding description.

[0068] The pouch product 100B of the second embodiment shown in Figures 10 and 11 includes pouch 1B in place of pouch 1A described above. Pouch 1B has a configuration that is substantially the same as pouch 1A described above. However, pouch 1B has protective sheet 5B in place of protective sheet 5A described above. Also, pouch 1B has two adhesive members 6.

[0069] The protective sheet 5B has a configuration that is generally the same as the protective sheet 5A described above. However, in addition to the continuous portion 51, opposing portion 52, and extended portion 53 described above, the protective sheet 5B has a continuous portion 54, an opposing portion 55, and a break line D. In order to distinguish between the two continuous portions 51 and 54, in this embodiment the continuous portion 51 is referred to as the first continuous portion 51, and the continuous portion 54 is referred to as the second continuous portion 54. Also, in order to distinguish between the two opposing portions 52 and 55, in this embodiment the opposing portion 52 is referred to as the first opposing portion 52, and the opposing portion 55 is referred to as the second opposing portion 55.

[0070] As shown in Figure 11, the second continuous portion 54 is a portion that is continuous with the second body portion 22. Specifically, the second continuous portion 54 is continuous with the second body portion 22 via the adhesive member 6. That is, the second continuous portion 54 is the portion that faces the second body portion 22, and the adhesive member 6 is placed between it and the second body portion 22. The second continuous portion 54 is located on the opposite side from the extended portion 53, with the second opposing portion 55 in between.

[0071] As shown in Figure 10, a fracture line D is formed between the second continuous section 54 and the second opposing section 55. The fracture line D is a linear section with lower strength than the adjacent sections on both sides of it (in this case, the second continuous section 54 and the second opposing section 55). The fracture line D is, for example, straight. The fracture line D is configured to be breakable by an external force. When the fracture line D is broken, the protective sheet 5B is separated between the second continuous section 54 and the second opposing section 55.

[0072] As shown in Figure 11, the second opposing portion 55 is the portion that faces the second body portion 22 when the break line D is not broken. Unlike the second continuous portion 54, no adhesive member 6 is placed between the second opposing portion 55 and the second body portion 22. For example, a gap is provided between the second opposing portion 55 and the second body portion 22.

[0073] As described in the first embodiment, the extended portion 53 is the part that extends outward from the upper edge 20 of the pouch body 2. The extended portion 53 connects the first opposing portion 52 and the second opposing portion 55. When the fracture line D is not fractured, the extended portion 53 is curved in a U-shape in cross-section so as to cover the spout 3 from the discharge port 33 side. When the fracture line D is fractured, the extended portion 53, together with the first opposing portion 52 and the second opposing portion 55, can form a continuous planar portion.

[0074] In this embodiment, when the ratio L2 / L1 described above is calculated, the length L2 of the extended portion 53 is the length L2 of the extended portion 53 when the fracture line D is fractured and the extended portion 53 is displaced until it becomes planar.

[0075] [2-2. Method of dispensing contents] If the user wishes to dispense the contents M from pouch 1B, they first break the break line D. Then, the user displaces the curved extension 53 until it becomes roughly flat. This exposes the spout 3 and the cap 4 attached thereto. After that, the user dispenses the contents M from the discharge port 33 using the same procedure as in the first embodiment. The user can use both a gripping-type dispensing method and a pressing-type dispensing method.

[0076] [2-3. Effect] In the pouch product 100B of the second embodiment, the portion of the protective sheet 5B separated by the break line D, including the first continuous portion 51, the first opposing portion 52, the extended portion 53, and the second opposing portion 55, performs the same function as the protective sheet 5A of the first embodiment. Therefore, even if the contents M drip from the discharge port 33, the contents M are more likely to fall onto the protective sheet 5B rather than onto the mounting surface S. In other words, the contents M are less likely to drip onto the mounting surface S.

[0077] [2-4. Effects] According to the second embodiment described in detail above, the same effects as the first embodiment can be obtained, and furthermore, the following effects can be obtained.

[0078] In the second embodiment, a break line D is formed on the protective sheet 5B. When the break line D is not broken, the extended portion 53 is curved in a U-shape in cross-section. With this configuration, when the break line D is not broken, the dimensions of the extended portion 53 along the central axis X of the spout 3 can be reduced. When the break line D is broken, the length L2 of the extended portion 53 can be secured. Therefore, the ease of handling of the pouch product 100B when the break line D is not broken can be improved while obtaining the same effects as in (1a) above.

[0079] [2-5. Correspondence] In the second embodiment, the pouch body 2 corresponds to an example of a storage section. The first body section 21 corresponds to an example of a first sheet section. The second body section 22 corresponds to an example of a second sheet section. The protective sheet 5B corresponds to an example of a protective section. As in the first embodiment, the front of the pouch product 100B is not particularly limited.

[0080] [3. Third Embodiment] [3-1. Composition of Pouch Products] The third embodiment has the same basic configuration as the first embodiment, so the differences will be explained below. Note that the same reference numerals as in the first embodiment indicate the same components, and refer to the preceding description.

[0081] The pouch product 100C of the third embodiment shown in Figure 12 is equipped with pouch 1C instead of the aforementioned pouch 1A. In the aforementioned pouch 1A, the pouch body 2 has the function of containing the contents M, and the protective sheet 5A has the function of preventing the contents M from dripping onto the mounting surface S. In contrast, in the pouch 1C of this embodiment, the pouch body 7 has both the function of containing the contents M and the function of preventing the contents M from dripping onto the mounting surface S. That is, pouch 1C has a pouch body 7, a spout 3, and a cap 4, and does not have a protective sheet 5A.

[0082] The pouch body 7 is configured to form a storage space R. The pouch body 7 has a first body portion 71, a second body portion 22, a third body portion 72, a bottom portion 23, a sealing portion 73, and a protective portion 74. The configuration of the second body portion 22 and the bottom portion 23 is as described in the first embodiment.

[0083] As shown in Figure 13, the first body section 71 and the third body section 72 are sheet-like. The first body section 71 and the third body section 72 are made of the aforementioned sheet material 25. The first body section 71 is positioned above the third body section 72 such that the lower edge E1 of the first body section 71 and the upper edge E2 of the third body section 72 are in contact with each other. In this arrangement, the overall shape and size of the first body section 71 and the third body section 72 combined is equal to that of the second body section 22. The first body section 71 and the third body section 72 are stacked on top of the second body section 22, with each side facing the other. The seal layers 251 of the first body section 71 and the third body section 72 face the seal layer 251 of the second body section 22. The bottom section 23 is positioned between the lower part of the second body section 22 and the lower part of the third body section 72, with the fold line F facing upwards.

[0084] As shown in Figures 12 and 13, the seal portion 73 is the portion where the edge of the second body portion 22 is directly or indirectly welded to the edge of the opposing first body portion 71 or third body portion 72. The edge of the first body portion 71 is the portion that constitutes the outer edge of the first body portion 71. The edge of the third body portion 72 is the portion that constitutes the outer edge of the third body portion 72.

[0085] The edge of the second body section 22 is basically directly welded to the edge of the first body section 71 or the third body section 72. However, a spout 3 is positioned between the first body section 71 and the second body section 22, on the side opposite to the bottom section 23. In the region where the spout 3 is positioned, the edge of the second body section 22 and the opposite edge of the first body section 71 are welded to the spout 3. That is, in that region, the edge of the second body section 22 and the opposite edge of the first body section 71 are indirectly welded to each other via the spout 3.

[0086] Furthermore, in the region where the bottom portion 23 is located between the second body portion 22 and the third body portion 72, the edge of the second body portion 22 and the edge of the third body portion 72 opposite to it are welded to the bottom portion 23. In other words, in that region, the edge of the second body portion 22 and the edge of the third body portion 72 opposite to it are indirectly welded to each other via the bottom portion 23. The edge of the second body portion 22 is welded along its entire circumference.

[0087] As shown in Figure 14, the protective portion 74 is the part that extends from the first body portion 71 beyond the discharge port 33. The protective portion 74 is sheet-like. The protective portion 74 is flexible.

[0088] In this embodiment, the protective portion 74 is the portion where the first extended portion 741 and the second extended portion 742 shown in Figure 13 are welded to each other. Both the first extended portion 741 and the second extended portion 742 are made of sheet material 25. The first extended portion 741 is the portion that extends from the lower edge E1 of the first body portion 71. The first extended portion 741 folds back and extends from the lower edge E1 of the first body portion 71. In other words, the first extended portion 741 extends upward. The second extended portion 742 is the portion that extends from the upper edge E2 of the third body portion 72. The second extended portion 742 extends upward. The second extended portion 742 may or may not be at an angle with the third body portion 72, for example.

[0089] As described above, by arranging the first body portion 71 and the third body portion 72 vertically, the first extended portion 741 and the second extended portion 742 are superimposed on each other. Specifically, the first extended portion 741 is positioned between the first body portion 71 and the second extended portion 742. The seal layers 251 of the first extended portion 741 and the second extended portion 742 face each other. Then, by applying at least one of heat and pressure, the first extended portion 741 and the second extended portion 742 are welded to each other. The first extended portion 741 and the second extended portion 742 are welded to each other over their entire areas. In this way, the protective portion 74 is formed.

[0090] As shown in Figure 14, the protective portion 74 has a continuous portion 51, an opposing portion 52, and an extended portion 53. These configurations are as described in the first embodiment.

[0091] However, in the first embodiment, the continuous portion 51 is continuous with the first body portion 21 via the adhesive member 6. In contrast, in the third embodiment, the continuous portion 51 is continuous with the first body portion 71 directly. In the third embodiment, the continuous portion 51 is a strip-shaped portion adjacent to the lower edge E1 of the first body portion 71 and the upper edge E2 of the third body portion 72.

[0092] Furthermore, in the first embodiment, the width W2 of the extended portion 53 in the direction perpendicular to the axial direction of the spout 3 is, for example, the same as or smaller than the width W3 of the pouch body 2. In this embodiment, the "width W3 of the pouch body 2" referred to here shall be read as "the width of the structure formed by the first body portion 71, the second body portion 22, the third body portion 72, the bottom portion 23, and the sealing portion 73." The two ratios L2 / L1 and W2 / W1 mentioned above can take the same values ​​as in the first embodiment in this embodiment as well.

[0093] As shown in Figure 12, the bottom portion 23 is widened so that the bending angle in the fold curve F increases, thereby increasing the distance between the first body portion 71 and the third body portion 72 and the second body portion 22. In other words, a storage space R is formed inside the pouch body 7. The storage space R is formed by the components of the pouch body 7, particularly the first body portion 71, the second body portion 22, the third body portion 72, the bottom portion 23, and the sealing portion 73. The pouch 1C is able to stand upright on the mounting surface S when the storage space R is formed. The pouch 1C is able to stand upright on the mounting surface S with the spout 3 side facing upwards and the bottom portion 23 side facing downwards (i.e., towards the mounting surface S).

[0094] [3-2. Method of dispensing contents] The user can dispense the contents M from pouch 1C in the same manner as in the first embodiment.

[0095] [3-3. Effect] In the pouch product 100C of the third embodiment, the protective part 74 performs the same function as the protective sheet 5A of the first embodiment. Therefore, even if the contents M drip from the discharge port 33, the contents M are more likely to fall onto the protective part 74 rather than onto the mounting surface S. In other words, the contents M are less likely to drip onto the mounting surface S.

[0096] [3-4. Effects] According to the third embodiment described in detail above, the same effects as the first embodiment can be obtained.

[0097] [3-5. Correspondence] In the third embodiment, the structure comprising the first body portion 71, the second body portion 22, the third body portion 72, the bottom portion 23, and the sealing portion 73 corresponds to an example of a housing portion. The first body portion 71 corresponds to an example of a first sheet portion. The second body portion 22 corresponds to an example of a second sheet portion. As with the first embodiment, the front of the pouch product 100C is not particularly limited.

[0098] [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.

[0099] (4a) In the protective sheets 5A and 5B of the first and second embodiments described above, the continuous portion 51 is positioned on the opposite side from the extended portion 53, with the opposing portion 52 in between. However, the arrangement of the continuous portion 51 in the protective sheets 5A and 5B is not particularly limited. The continuous portion 51 may be positioned, for example, adjacent to the opposing portion 52 when viewed from the axial direction of the spout 3.

[0100] (4b) In the first and third embodiments described above, the protective sheet 5A or protective part 74 has an opposing part 52, but it does not necessarily have to have an opposing part 52. The protective sheet 5B of the second embodiment has a first opposing part 52 and a second opposing part 55, but for example, it does not have to have at least one of these opposing parts 52 and 55.

[0101] Even if the protective sheets 5A, 5B or protective part 74 do not have opposing parts 52, 55, in a press-type discharge method, if the contents M drip from the discharge port 33, the contents M are more likely to fall onto the protective sheets 5A, 5B or protective part 74 rather than onto the mounting surface S. Therefore, the same effect as in (1a) above can be obtained.

[0102] (4c) In the second embodiment described above, a break line D is formed in the protective sheet 5B. When the user wants to dispense the contents M from the pouch 1B, they first break the break line D to expose the spout 3.

[0103] However, in addition to or instead of forming a break line D in the protective sheet 5B, for example, the adhesive member 6 that adheres the protective sheet 5B to the second body portion 22 may be configured to peel off from at least one of the protective sheet 5B and the second body portion 22. With such a configuration, if the user wants to dispense the contents M from the pouch 1B, they can expose the spout 3 by peeling the protective sheet 5B from the adhesive member 6, or by peeling the adhesive member 6 together with the protective sheet 5B from the second body portion 22.

[0104] (4d) The protective sheet 5A in the first embodiment, the protective sheet 5B in the second embodiment that has been displaced until it is planar, and the protective part 74 in the third embodiment are rectangular in shape. However, the shapes of the protective sheets 5A, 5B and the protective part 74 are not particularly limited.

[0105] (4e) In the above embodiment, the pouch body 2,7 ​​is configured to be self-supporting, but it does not necessarily have to be configured to be self-supporting. For example, the pouch body 2,7 ​​does not have to have a bottom 23.

[0106] (4f) The surfaces of the protective sheets 5A, 5B and the protective part 74 may, for example, be marked with information relating to the pouch products 100A, 100B, and 100C. Specific examples of markings relating to the pouch products 100A, 100B, and 100C include product information for the pouch products 100A, 100B, and 100C, product labeling such as instructions on how to dispense the contents M, and advertising text intended to promote sales.

[0107] (4g) 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 of the configurations of the above embodiment may be omitted. In addition, at least some of the configurations of the above embodiment may be added to, replaced with, or otherwise adapted to the configurations of other above embodiments.

[0108] (4h) This disclosure can be implemented in various forms, including the aforementioned pouches 1A, 1B, and 1C, as well as pouch products 100A, 100B, and 100C that consist of the pouches 1A, 1B, and 1C, and a method for dispensing the contents M.
