[0003] Patent Document 1 Japanese Patent No. 6454604 Summary of the Invention Problem to be Solved by the Invention

[0004] However, in conventional foam discharge containers, for example, the foam quality of the foam tends to vary depending on the number of times the container body is shaken, room temperature, and other factors, and there is a risk that the foam quality of the foam discharged from the foam discharge hole is difficult to stabilize. Furthermore, when assembling the foam discharge container, it is necessary to align the relative positions in the circumferential direction between the container body, the cap body, and the inner plug, leaving room for improvement in assemblability.

[0005] The present invention provides a foam discharge container capable of stabilizing the foam quality of foam discharged from a foam discharge hole and improving assemblability. [Means for solving the problem]

[0006] A foam dispensing container according to one aspect of the present invention comprises a container body having a storage portion that contains a liquid and is at least partially elastically deformable, and a mouth portion that extends upward from the upper end of the storage portion, a cap body attached to the mouth portion, and a stopper that is liquid-tightly fitted to the upper end opening of the storage portion, wherein the mouth portion and the upper end opening of the storage portion are arranged coaxially, the cap body has a foam dispensing hole for dispensing foam from the liquid content, the container body has a communication passage that connects the inside of the storage portion and the inside of the mouth portion, the inside of the mouth portion is provided with a communication space that extends continuously around the entire circumference along the central axis of the mouth portion and opens to the upper end opening of the communication passage, a communication hole that opens to the communication space and communicates with the foam dispensing hole, and a porous body that covers the communication hole and through which foam can pass.

[0007] After shaking the foam dispensing container to foam the liquid inside the container, the container is pressed and compressed (squeezed), which pressurizes the container. The foamed liquid then passes through the connecting passages, connecting spaces, and connecting holes and is discharged from the foam dispensing holes. At this time, since the connecting holes are covered with a porous material, the foam is discharged from the foam dispensing holes after passing through the porous material and having its foam quality adjusted. This stabilizes the foam quality of the foam discharged from the foam dispensing holes. Subsequently, when the pressure on the containment section is released and the containment section is restored to its original shape, the pressure inside the containment section decreases, and outside air flows into the opening through the foam discharge hole. At this time, the foam located directly below the foam discharge hole further foams as it passes through the porous section toward the downward side of the connecting passage. This reduces the number of times the foam discharge container needs to be shaken when dispensing foam next time. The upper end openings of the mouth and the housing are arranged coaxially, and within the mouth there is a communication space that extends continuously around the entire circumference along the central axis of the mouth and through which the upper end opening of the communication passage opens, and a communication hole that opens into the communication space and communicates with the foam discharge hole. Therefore, when fitting the inner stopper into the upper opening of the housing, it is not necessary to align the relative circumferential positions of the inner stopper and the container body, nor is it necessary to align the relative circumferential positions of the cap body and the container body when attaching the cap body to the mouth. In such cases, at least the communication passage and the connecting hole can be connected through the communication space, thereby improving ease of assembly.

[0008] The cap body may support the inner stopper from above.

[0009] Since the cap body supports the inner plug from above, it prevents the inner plug from easily coming out upward from the upper opening of the housing when the housing is pressurized.

[0010] The cap body may be provided with a retaining portion for holding the inner stopper.

[0011] Since the cap body is provided with a retaining part for holding the inner stopper, the inner stopper can be assembled to the cap body in advance, and then the cap body and inner stopper can be attached to the container body as a single unit without the need for alignment, making it easy to assemble the foam dispensing container.

[0012] The cap body may be provided with a connecting space that extends continuously around the entire circumference along the central axis of the mouth, and through which the connecting hole and the foam discharge hole are opened.

[0013] Since the cap body is provided with a connecting space that extends continuously around the entire circumference along the central axis of the opening, and through which a connecting hole and a foam discharge hole are opened, even if the inner stopper and the cap body are attached to the container body without aligning their relative positions in the circumferential direction with respect to the container body, the communication passage and the foam discharge hole can be connected through the connecting space, the connecting hole and the connecting space, thereby reliably improving ease of assembly. [Effects of the Invention]

[0014] According to one aspect of the present invention, the foam quality of the foam discharged from the foam discharge hole can be stabilized, and the ease of assembly can be improved. [Brief explanation of the drawing]

[0015] [Figure 1] This is a longitudinal cross-sectional view of the foam dispensing container shown as the first embodiment. [Figure 2] This is a cross-sectional view taken along the line II-II in Figure 1. [Figure 3] This is a longitudinal cross-sectional view of the foam dispensing container shown as the second embodiment. [Figure 4] This is a longitudinal cross-sectional view of the foam dispensing container shown as the third embodiment. [Modes for carrying out the invention]

[0016] A foam dispensing container according to the first embodiment of the present invention will be described below with reference to the drawings. As shown in Figure 1, the foam dispensing container 1 according to this embodiment comprises a container body 10 having a mouth 11, a cap body 20 attached to the mouth 11, and an inner stopper 30. The cap body 20 is formed in a top-shaped cylindrical form having a cap top wall 21a and includes a main body cylindrical portion 21 attached to the mouth 11. The inner stopper 30 is formed in a top-shaped cylindrical form having an inner stopper top wall 30a. The main body cylindrical portion 21, the mouth 11, and the inner stopper 30 are arranged coaxially with a common axis.

[0017] Hereinafter, this common axis will be referred to as the container axis O (central axis), the side of the cap top wall 21a along the container axis O will be referred to as the upper side, the side of the bottom 12 of the container body 10 along the container axis O will be referred to as the lower side, and the direction along the container axis O will be referred to as the vertical direction. When viewed from the vertical direction, the direction that intersects the container axis O will be referred to as the radial direction, and when viewed from the vertical direction, the direction that circles around the container axis O will be referred to as the circumferential direction.

[0018] The container body (10) comprises a mouth portion (11), a storage portion (13), a bottom portion (12), and a communication passage (14). The mouth portion (11), the storage portion (13), and the bottom portion (12) are arranged connected in this order from top to bottom. The mouth portion (11), the storage portion (13), the bottom portion (12), and the communication passage (14) are integrally formed of a synthetic resin material. Note that the communication passage (14) may be formed separately from the mouth portion (11), the storage portion (13), and the bottom portion (12).

[0019] A content liquid is stored in the storage portion (13). The storage portion (13) includes a body portion (13a) that extends straight upward from the bottom portion (12), a shoulder portion (13b) that extends radially inward as it goes upward from the upper end of the body portion (13a), and a neck portion (upper end portion) (13c) that extends straight upward from the upper end of the shoulder portion (13b). Among the storage portion (13), at least the body portion (13a) is formed to be elastically deformable. As shown in Figure 2, the storage portion (13) has a circular shape when viewed in the vertical direction. The inner side of the neck portion (13c), which is the upper end opening (13f) of the storage portion (13), has a circular shape arranged coaxially with the container axis O when viewed in the vertical direction. The mouth portion (11) extends upward from the neck portion (13c).

[0020] The communication passage (14) is formed in a tubular shape extending downward along the storage portion (13) from the lower end opening of the mouth portion (11), and communicates the inside of the storage portion (13) with the inside of the mouth portion (11). The lower end opening (14a) of the communication passage (14) is located above the bottom portion (12) and opens into the lower end portion of the storage portion (13). The upper end opening (14b) of the communication passage (14) opens into the lower end portion of the mouth portion (11).

[0021] As shown in Figure 2, on the outer peripheral surfaces of the shoulder portion (13b) and the body portion (13a) located below the neck portion (13c) in the storage portion (13), there are formed vertical grooves (13d) that are recessed radially inward and extend in the vertical direction, and the communication passage (14) is accommodated in the vertical groove (13d). The communication passage (14) is connected to the storage portion (13) via a connecting rib (13e) that protrudes radially outward from the radially inner end of the inner surface of the vertical groove (13d).

[0022] The cap body (20) comprises a main body cylinder portion (21) and a lid body (23).

[0023] The main cylindrical portion 21 is externally attached to the mouth portion 11. The main cylindrical portion 21 has a foam discharge hole 22 that communicates with the storage portion 13 and discharges the foamed liquid contents. The foam discharge hole 22 is formed in the cap top wall 21a of the main cylindrical portion 21 and opens into the mouth portion 11. The central axis of the foam discharge hole 22 is radially separated from the container axis O. The foam discharge hole 22 communicates with the upper end opening 14b of the communication passage 14 through the mouth portion 11.

[0024] The lid 23 is connected to the main body cylindrical portion 21 via a hinge portion 25. The lid 23 rotates vertically around the hinge portion 25 to open and close the foam discharge hole 22. The hinge portion 25 is located on the opposite side of the foam discharge hole 22, sandwiching the container axis O radially. Note that the hinge portion 25 and the lid 23 are not required.

[0025] A retaining portion 26 for holding the inner stopper 30 is provided on the main cylindrical portion 21. The retaining portion 26 is formed in a cylindrical shape extending downward from the top wall 21a of the cap and is arranged coaxially with the container axis O. The retaining portion 26 is fitted liquid-tightly into the mouth portion 11. A foam discharge hole 22 opens on the inside of the retaining portion 26. The lower end of the retaining portion 26 is located above the lower end of the inner circumferential surface of the mouth portion 11.

[0026] The main cylindrical portion 21 supports the inner stopper 30 from above. In this embodiment, a cylindrical support portion 27 is formed on the main cylindrical portion 21, extending downward from a portion of the cap top wall 21a that is radially inward from the inner circumferential surface of the holding portion 26 and the foam discharge hole 22. The lower end of the support portion 27 is located above the lower end of the holding portion 26. The lower end opening edge of the support portion 27 abuts against the upper surface of the inner stopper top wall 30a via a porous body 35, which will be described later. The support portion 27 is arranged coaxially with the container axis O, but the central axis of the support portion 27 may be radially separated from the container axis O.

[0027] A foam discharge hole 22 is located in the portion of the main body cylindrical portion 21 between the outer circumferential surface of the support portion 27 and the inner circumferential surface of the holding portion 26 (hereinafter referred to as the connection space 31). The connection space 31 extends continuously around its entire circumference. The connection space 31 is formed in an annular shape and is arranged coaxially with the container axis O. Part of the partition wall of the connection space 31 is formed by the cap top wall 21a.

[0028] The inner stopper periphery wall 30b of the inner stopper 30 is liquid-tightly fitted into the upper end opening 13f of the housing section 13. The inner stopper top wall 30a is located above the upper end opening 13f of the housing section 13 and is located within the mouth section 11. The inner stopper top wall 30a is located below the cap top wall 21a. Multiple vertical ribs 30c are formed on the outer circumferential surface of the inner stopper periphery wall 30b, projecting radially outward and extending vertically, at intervals in the circumferential direction. The lower end surfaces of the vertical ribs 30c abut against the peripheral edge of the upper end opening 13f of the housing section 13 on the inner surface of the container body 10.

[0029] The outer periphery of the top wall 30a of the plug protrudes radially outward from the circumferential wall 30b of the plug. A mounting cylinder 32 extending downward is formed on the outer periphery of the top wall 30a of the plug. The upper part of the mounting cylinder 32 is liquid-tightly fitted into the retaining part 26, and the lower part protrudes downward from the retaining part 26. Within the opening 11, the space between the inner circumferential surface of the mounting cylinder 32 and the upper outer circumferential surface of the inner plug circumferential wall 30b located above the upper end opening 13f of the housing section 13 is a connecting space 33 that extends continuously around the entire circumference and through which the upper end opening 14b of the connecting passage 14 opens. The connecting space 33 is formed in an annular shape and is arranged coaxially with the container axis O. A connecting hole 34 is formed on the outer circumference of the top wall 30a of the central plug, penetrating vertically and opening into the communication space 33 and the connecting space 31, and communicating with the foam discharge hole 22 through the connecting space 31. Multiple connecting holes 34 are provided at intervals in the circumferential direction.

[0030] A porous body 35 is provided inside the opening 11, covering the connecting hole 34 and allowing the foam to pass through. The porous body 35 is a sheet-like mesh and is fixed to the upper surface of the top wall 30a of the inner plug. The porous body 35 is provided over the entire upper surface of the top wall 30a of the inner plug. The lower end opening edge of the support portion 27 abuts against the upper surface of the porous body 35. The porous body 35 may be, for example, a three-dimensional network structure, and the porous body 35 may be attached only to the upper surface of the plug top wall 30a, specifically to the peripheral edge of the opening of the connecting hole 34.

[0031] Next, the operation of the foam dispensing container 1 will be explained.

[0032] After shaking the foam dispensing container 1 to foam the liquid contents in the containment section 13, the lid 23 is rotated upward around the hinge section 25 to open the foam dispensing hole 22. Next, for example, with the mouth section 11 facing downward, the body section 13a of the containment section 13 is pressed and compressed (squeezed), which pressurizes the inside of the containment section 13, causing the foamed liquid contents to pass through the communication passage 14, the connecting space 33, the connecting hole 34, and the connecting space 31 in that order and be discharged from the foam dispensing hole 22. In this case, since the connecting hole 34 is covered by the porous body 35, the foam, whose foam quality has been adjusted by passing through the porous body 35, is discharged from the foam discharge hole 22. This makes it possible to stabilize the foam quality of the foam discharged from the foam discharge hole 22.

[0033] Subsequently, when the pressure on the housing section 13 is released and the housing section 13 is restored to its original shape, the pressure inside the housing section 13 decreases, and outside air flows into the opening 11 through the foam discharge hole 22. At this time, the foam located in the connecting space 31 further foams as it passes through the porous body 35 toward the downward side of the connecting passage 14. This reduces the number of times the foam discharge container 1 needs to be shaken when discharging the foam next time.

[0034] As described above, in the foam dispensing container 1 according to this embodiment, the mouth portion 11 and the upper end opening 13f of the housing portion 13 are arranged coaxially, and within the mouth portion 11, there is a communication space 33 that extends continuously around the entire circumference along the container axis O and into which the upper end opening 14b of the communication passage 14 is opened, and a communication hole 34 that opens into the communication space 33 and communicates with the foam dispensing hole 22. Therefore, when fitting the inner stopper 30 into the upper end opening 13f of the housing section 13, it is not necessary to align the relative circumferential positions of the inner stopper 30 and the container body 10, nor is it necessary to align the relative circumferential positions of the cap body 20 and the container body 10 when attaching the cap body 20 to the mouth section 11. In such cases, at least the communication passage 14 and the communication hole 34 can be connected through the communication space 33, thereby improving ease of assembly.

[0035] Based on the above, it is possible to stabilize the foam quality of the foam discharged from the foam discharge hole 22 and improve the ease of assembly.

[0036] Since the cap body 20 supports the inner plug 30 from above, it is possible to prevent the inner plug 30 from easily coming out upward from the upper end opening 13f of the housing 13 when the housing 13 is pressurized.

[0037] Since the cap body 20 is provided with a holding portion 26 for holding the inner stopper 30, the inner stopper 30 can be assembled to the cap body 20 in advance, and then the cap body 20 and inner stopper 30 can be attached to the container body 10 as a single unit without the need for alignment, making it easy to assemble the foam dispensing container 1.

[0038] Since the cap body 20 is provided with a connecting space 31 that extends continuously around the entire circumference of the container axis O and through which the connecting hole 34 and the foam discharge hole 22 are opened, even if the inner stopper 30 and the cap body 20 are attached to the container body 10 without aligning their relative positions in the circumferential direction with respect to the container body 10, the communication passage 14 and the foam discharge hole 22 can be connected through the connecting space 33, the connecting hole 34, and the connecting space 31, thereby reliably improving ease of assembly.

[0039] Next, a foam dispensing container 2 according to the second embodiment of the present invention will be described with reference to Figure 3. In this second embodiment, the same reference numerals are used for parts that are the same as those in the first embodiment, and their descriptions are omitted. Only the differences will be described.

[0040] In this embodiment, the foam dispensing container 2 does not have a connection space 31 and a support portion 27. The top wall 30a of the inner stopper is located below the lower end of the retaining portion 26, and the outer circumferential surface of the top wall 30a of the inner stopper is in contact with or close to the inner circumferential surface of the lower end of the mouth portion 11. The mounting cylinder 32 extends upward from the outer circumferential portion of the top wall 30a of the inner stopper, with the upper part of the mounting cylinder 32 fitting liquid-tightly into the retaining portion 26 and the lower part protruding downward from the retaining portion 26. The lower surface of the top wall 30a of the inner stopper is located above the periphery of the upper end opening 13f of the housing portion 13 and the upper end opening 14b of the communication passage 14 on the inner surface of the container body 10.

[0041] The communication space 33 is defined by the lower surface of the top wall 30a of the inner stopper, the inner circumferential surface of the lower end of the mouth portion 11, the outer circumferential surface of the upper end of the inner stopper's circumferential wall 30b located above the upper end opening 13f of the housing portion 13, and the periphery of the upper end opening 13f of the housing portion 13 and the upper end opening 14b of the communication passage 14 on the inner surface of the container body 10. The communication space 33 is formed in an annular shape and is arranged coaxially with the container axis O.

[0042] A connecting cylinder 36 extending upward is formed on the top wall 30a of the plug. A portion of the peripheral wall of the connecting cylinder 36 is integrally formed with the mounting cylinder 32, and when viewed from above, the connecting cylinder 36 is positioned to be inscribed within the mounting cylinder 32. The connecting cylinder 36 is arranged coaxially with the foam discharge hole 22. One connecting hole 34 is formed in the top wall 30a of the plug, in the portion located inside the connecting cylinder 36. The connecting hole 34 opens into the connecting space 33 and communicates with the foam discharge hole 22 through the inside of the connecting cylinder 36.

[0043] The porous body 35 is attached and fixed to a portion of the opening periphery of the connecting hole 34 on the lower surface of the top wall 30a of the plug. A connecting cylinder 28 is formed at the periphery of the opening of the foam discharge hole 22 on the lower surface of the cap top wall 21a, projecting downward. The lower end of the connecting cylinder 28 is located above the top wall 30a of the inner plug. The connecting cylinder 28 is liquid-tightly fitted inside the connecting cylinder 36. The lower surface of the cap top wall 21a abuts against the upper opening edges of the mounting cylinder 32 and connecting cylinder 36 of the inner stopper 30, thereby supporting the inner stopper 30 from above with the main body cylinder portion 21.

[0044] As described above, with the foam dispensing container 2 according to this embodiment, when the same operation as in the first embodiment is performed and the inside of the containment section 13 is pressurized, the foam of the liquid contents passes through the communication passage 14, the connecting space 33, the porous body 35, the connecting hole 34, the connecting cylinder 36, and the connecting cylinder 28 in that order and is discharged from the foam dispensing hole 22. This stabilizes the foam quality of the foam discharged from the foam dispensing hole 22 and improves ease of assembly.

[0045] Next, a foam dispensing container 3 according to the third embodiment of the present invention will be described with reference to Figure 4. In this third embodiment, the same reference numerals are used for parts that are the same as those in the first embodiment, and their descriptions are omitted. Only the differences will be described.

[0046] In the foam dispensing container 3 of this embodiment, the inner stopper 30 is not provided with vertical ribs 30c, mounting cylinder 32, and connecting hole 34, and the lower surface of the outer peripheral edge of the top wall 30a of the inner stopper abuts against the peripheral edge of the upper end opening 13f of the housing portion 13 on the inner surface of the container body 10. A fixed cylinder 41 extending downward is formed on the top wall 21a of the cap. A foam discharge hole 22 is opened inside the fixed cylinder 41. The fixed cylinder 41 is arranged coaxially with the container axis O.

[0047] The main cylindrical portion 21 is provided with a connecting hole 34 and a support portion 27, and a relay member 40 is fitted onto and fixed to the fixing cylinder 41. The intermediate member 40 is formed in the shape of a bottomed cylinder and is arranged coaxially with the container axis O. The fixed cylinder 41 is undercut-fitted into the peripheral wall of the intermediate member 40. A cylindrical body is formed on the top wall 21a of the cap, surrounding the fixed cylinder 41 from the radial outside, and the peripheral wall of the intermediate member 40 is fitted into this cylindrical body. The bottom wall of the intermediate member 40 is located below the top wall 21a of the cap and above the top wall 30a of the inner stopper. Multiple connecting holes 34 are formed in the bottom wall of the intermediate member 40 at circumferential intervals. The support portion 27 extends downward from the bottom wall of the intermediate member 40. The lower end surface of the support portion 27 abuts against the upper surface of the top wall 30a of the inner plug. The support portion 27 is arranged coaxially with the container axis O. The support portion 27 is formed in the shape of a solid rod, but it may also be formed in the shape of a cylinder. The porous body 35 is provided and fixed over the entire lower surface of the bottom wall of the relay member 40, excluding the portion connected to the support 27.

[0048] The connecting space 33 through which the upper end opening 14b of the connecting passage 14 opens is defined at least by the lower surface of the bottom wall of the relay member 40, the upper surface of the top wall 30a of the inner stopper, and the peripheral edges of the upper end opening 13f of the housing section 13 and the upper end opening 14b of the connecting passage 14, respectively, and the inner circumferential surface of the mouth section 11 on the inner surface of the container body 10. The connecting space 31, through which the connecting hole 34 and the foam discharge hole 22 open, is defined by at least the upper surface of the bottom wall of the relay member 40, the inner circumferential surface of the fixed cylinder 41, and the lower surface of the cap top wall 21a. The connecting space 31 is a cylindrical space that extends continuously along its entire length not only in the circumferential direction but also in the radial direction.

[0049] The foam dispensing container 3 is obtained by fitting the inner stopper 30 into the upper end opening 13f of the housing section 13, assembling the intermediate member 40 to the fixing cylinder 41 of the main body cylindrical section 21, and then attaching the assembly of the cap body 20 and the intermediate member 40 to the mouth section 11.

[0050] As described above, with the foam dispensing container 3 according to this embodiment, when the same operation as in the first embodiment is performed and the inside of the containment section 13 is pressurized, the foam of the liquid contents passes through the communication passage 14, the connecting space 33, the porous body 35, the connecting hole 34, and the connecting space 31 in that order and is discharged from the foam dispensing hole 22. This stabilizes the foam quality of the foam discharged from the foam dispensing hole 22 and improves the ease of assembly.
