[0016] Hereinafter, the refillable cap 1 and the container 100 according to the first embodiment of the present disclosure will be described in detail with reference to the drawings.

[0017] In this specification and claims, the up-down direction means the upper and lower directions when the container 100 is in an upright position as shown in Fig. 1. Furthermore, the radially inward direction means the direction toward the central axis O of the container 100 in Fig. 1 along a straight line passing through the central axis O and perpendicular to the central axis O, and the radially outward direction means the direction away from the central axis O along a straight line passing through the central axis O and perpendicular to the central axis O.

[0018] In this embodiment, the weakened portion is a portion that is configured to be more easily broken than the surrounding area, such as a portion that is thinner or narrower than the surrounding area, or a portion that has intermittent notches to make the non-notched portion more easily broken.

[0019] The container 100 of this embodiment shown in Figure 1 comprises a container body 2 that contains the liquid contents, a crown 80 (stopper) that is plugged into the upper end of the mouth 4 of the container body 2 to close the mouth 4, and a replacement cap 1 that is attached to the mouth 4.

[0020] In this embodiment, the container body 2 is a glass container, and has a substantially cylindrical mouth 4 to which the replacement cap 1 is attached, a body 5 that is connected to the lower end of the mouth 4 via a shoulder 7 and forms a storage space S for the liquid content, and a bottom (not shown) that closes the lower end of the body 5. The container body 2 can be formed, for example, by blow molding a glass parison.

[0021] In this embodiment, the mouth 4 is substantially cylindrical and serves as a discharge port for the contents contained in the storage space S. A bulge 4a is integrally formed on the outer circumferential surface of the upper end of the mouth 4 for attaching a crown 80 that closes the mouth 4 by undercut engagement (stoppering engagement).

[0022] The opening 4 may be provided with a male thread for attaching the replacement cap 1 by screw engagement instead of by tapping engagement.

[0023] The body 5 is integrally connected to the lower end of the mouth 4 via a shoulder 7, and has a cylindrical shape with approximately the same diameter extending downward. A neck ring 4b is integrally provided at the lower part of the mouth 4. The neck ring 4b protrudes radially outward from the mouth 4 and is approximately annular in shape extending around the entire circumference centered on the central axis O.

[0024] Crown cap 80 engages with and closes mouth 4 of container body 2. Crown cap 80 includes a side wall 81, a top wall 83 that closes the upper end of side wall 81, and a gasket 85 provided on the underside of top wall 83 to seal the gap between the side wall 81 and mouth 4. Side wall 81 is provided with an annular recess 81a on its radially inner side that undercuts and engages with bulging portion 4a of recessed mouth 4. Steel plate, aluminum plate, or the like can be used as materials for side wall 81 and top wall 83. Gasket 85 can be made of polyethylene (PE) resin, cork sheet, polyvinyl chloride (PVC) resin, or the like.

[0025] As the stopper for closing the mouth 4, in addition to the crown cap 80, a cork stopper, a stopper made of synthetic resin, or the like can be used.

[0026] As shown in Figure 1, the replacement cap 1 comprises a dispensing member 10 having a dispensing hole 14a for dispensing the liquid contents contained in the container body 2, a lid body 20 formed integrally with the dispensing member 10 and closing the dispensing hole 14a from above, and a cylindrical member 30 having an annular protrusion 31b (engagement portion) that undercuts and engages with the neck ring 4b of the mouth portion 4 and restricts the upward and radially outward displacement of the dispensing member 10.

[0027] The dispensing member 10 includes a peripheral wall 11 having an outer diameter smaller than the inner diameter of the mouth portion 4, a top wall 13 on which a dispensing tube 14 is erected that closes the upper end of the peripheral wall 11 and forms a dispensing hole 14a on its upper surface, and a flange portion 12 (sealing portion) that protrudes radially outward from the peripheral wall 11 and has an outer diameter at its outer peripheral end larger than the inner diameter of the mouth portion 4. When the dispensing member 10 is removed from the tubular member 30 and inserted into the mouth portion 4 as described below, the outer peripheral end of the flange portion 12 abuts against the inner peripheral surface of the mouth portion 4, thereby liquid-tightly sealing the storage space S of the container body 2 from the outside (see FIG. 7).

[0028] The materials for the dispensing member 10 and the lid 20 can be various materials that can provide the flange portion 12 with appropriate elasticity to function as a sealing portion, such as soft synthetic resins such as soft polyethylene, thermoplastic elastomers, or rubber materials.

[0029] A lid body 20 that covers the dispensing hole 14a is provided above the dispensing member 10 and is integrated with the dispensing member 10 via a hinge portion 18. The lid body 20 includes a peripheral wall 21 that covers the dispensing tube 14 from the radially outer side, and a top wall 23 that closes the upper end of the peripheral wall 21 and covers the dispensing tube 14 from above. The lid body 20 is integrated with the dispensing member 10 at the lower end of the peripheral wall 21 via the hinge portion 18. A sealing cylinder wall 25 hangs down from the lower surface of the top wall 23, and in FIG. 1, the sealing cylinder wall 25 fits into the inner circumferential surface of the dispensing tube 14, thereby liquid-tightly sealing and closing the dispensing hole 14a.

[0030] The cylindrical member 30 includes an outer peripheral wall 31 that surrounds the mouth portion 4 from the radial outside, and an upper wall 33 that closes the upper end of the outer peripheral wall 31. A weakened portion 31a that is thinner than other regions of the outer peripheral wall 31 is provided in the outer peripheral wall 31 near the radial outside of the neck ring 4b. In addition, an annular protrusion 31b that protrudes radially inward and engages with the neck ring 4b by undercut is provided below the weakened portion 31a.

[0031] As shown in FIG. 2, support ribs 31c are provided in a region of the outer peripheral wall 31 radially outward of the top wall 13, supporting the top wall 13 from the radially outward side. In the illustrated example, the support ribs 31c are provided at 12 equally spaced locations in the circumferential direction. Except for the hinge portion 18 side and a portion opposite the hinge portion 18, the outer peripheral end of the top wall 13 fits into the inner peripheral end of the support ribs 31c, thereby restricting radially outward displacement of the pouring member 10. In this embodiment, as shown in FIG. 1 and other figures, the side wall 81 of the crown 80 abuts against the inner peripheral surface of the support rib 31c, thereby supporting the outer peripheral wall 31 by the side wall 81 of the crown 80. Furthermore, the upper wall 33 of the tubular member 30 via the lid 20 restricts upward displacement of the pouring member 10.

[0032] 3 and 4, the replacement cap 1 has a pressing portion 33a that can be pressed downward in the radial center of the upper wall 33. As shown in FIG. 4, the pressing portion 33a is supported by a hinge portion 33c and a weakened portion 33b in an unused state.

[0033] When using a container 100 equipped with a reusable cap 1 having the above configuration, a user first breaks the weakened portion 31a on the outer wall 31 from the state shown in FIG. 1 to release the undercut engagement between the neck ring 4b and the annular protrusion 31b. To release the undercut engagement, as described below, the bridge portion 31g (see FIG. 13) located directly below the weakened portion 31a is torn off, and the weakened portion 31a is sequentially broken in the circumferential direction, thereby removing the area of ​​the tubular member 30 below the weakened portion 31a (see FIG. 14). Since the undercut engagement is released by breaking the weakened portion 31a, the user can remove the reusable cap 1 from the opening 4 of the container body 2 by moving it upward. Then, the stopper (crown cap 80) is removed.

[0034] Next, after placing the removed replacement cap 1 on a stable location such as a desk, the user presses downward the pressing portion 33a of the cylindrical member 30 using the index finger or the like. This breaks the weakened portion 33b, and as shown in Figure 5, the spouting member 10 and the lid body 20 are pressed downward by the pressing portion 33a that has rotated around the hinge portion 33c, and the engagement between the top wall 13 and the support rib 31c is released, allowing them to be removed from the replacement cap 1.

[0035] A user attaches the dispensing member 10 and the lid 20 shown in the perspective view of Fig. 6 to the mouth 4 of the container body 2. When attaching the dispensing member 10, the lower end of the peripheral wall 11 is inserted into the mouth 4 from the upper opening of the mouth 4. Because the outer diameter of the flange 12 is larger than the inner diameter of the mouth 4, the flange 12 abuts against the mouth 4. However, as shown in Fig. 7, by pushing the dispensing member 10 downward while elastically deforming the outer peripheral end of the flange 12 so as to displace upward, the dispensing member 10 can be attached to the mouth 4 with the flange 12 liquid-tightly sealing the storage space S from the outside.

[0036] As described above, this embodiment is a replacement cap 1 to be attached to a container body 2 whose mouth 4 is closed by a stopper (crown cap 80). The replacement cap 1 is configured to include a dispensing member 10 having a dispensing hole 14a for dispensing the contents contained in the container body 2, and a tubular member 30 having an engaging portion (annular protrusion 31b) that engages with the outer surface of the mouth 4 below the stopper and restricts upward and radially outward displacement of the dispensing member 10 when the lower portion of the dispensing member 10 abuts against the top wall 83 of the stopper or the upper end of the mouth 4. With this configuration, the tubular member 30 that secures the dispensing member 10 engages with the mouth 4 via the engaging portion provided below the stopper, so that the tubular member 30 is supported not only by the stopper or the mouth 4 via at least the dispensing member 10 but also by the engaging portion. In particular, in the example shown in FIG. 1 , the outer peripheral wall 31 of the tubular member 30 is also supported by the side surface (side wall 81) of the stopper (crown cap 80). Therefore, when the cap is unused, the inclination of the cylindrical member 30 relative to the opening 4 can be suppressed, and the replacement cap 1 can be made less likely to come off the opening 4.

[0037] In this way, in this embodiment, a replacement cap 1 equipped with a pouring hole 14a is attached to the mouth portion 4 instead of a stopper (crown 80), so that a container 100 that is easy to use and does not drip when pouring the contents can be provided.

[0038] Furthermore, in this embodiment, the pouring member 10 is configured to include a peripheral wall 11 having an outer diameter smaller than the inner diameter of the mouth portion 4, a top wall 13 that closes the upper end of the peripheral wall 11 and is provided with a pouring hole 14a, and a seal portion (flange portion 12) that protrudes radially outward from the peripheral wall 11 and is formed of an elastic member whose outer diameter at its outer peripheral end is larger than the inner diameter of the mouth portion 4. By employing such a configuration, the seal portion can abut against the inner surface of the mouth portion 4 while elastically deforming to match the inner diameter dimension of the mouth portion 4. Therefore, even if the container body 2 is made of, for example, a glass material and the inner diameter dimension of the mouth portion 4 varies greatly during manufacturing, the seal portion can elastically deform in accordance with the inner diameter dimension, thereby maintaining the seal between the inside of the storage space S and the outside.

[0039] In this embodiment, the cylindrical member 30 is configured to have a weakened portion 31a above the engagement portion. By adopting this configuration, the user can irreversibly release the engagement between the cylindrical member 30 and the mouth portion 4 of the container body 2 by breaking the weakened portion 31a of the cylindrical member 30. Therefore, the replacement cap 1 can be easily removed from the container 100, and the container 100 can be brought into a usable state as shown in Figure 7. Furthermore, the irreversible breaking of the weakened portion 31a can provide the container 100 with an unused guarantee function.

[0040] In this embodiment, the cylindrical member 30 is a topped cylindrical member having an upper wall 33 that covers the dispensing member 10 from above, and the upper wall 33 is configured to have a pressing portion 33a that pushes the dispensing member 10 downward. By adopting this configuration, the dispensing member 10 can be easily removed from the replacement cap 1, and the container 100 can be easily transferred to the usable state shown in Figure 7.

[0041] In this embodiment, the lid 20 that covers the pouring hole 14a is integrally formed with the pouring member 10. By adopting such a configuration, the number of parts of the container 100 and the number of assembly steps can be reduced.

[0042] This embodiment also relates to a container 100 including a container body 2 for accommodating contents, a stopper (crown cap 80) for closing the mouth 4 of the container body 2, and a replacement cap 1 for attaching to the mouth 4. The replacement cap 1 is configured to include a dispensing member 10 having a dispensing hole 14a for dispensing the contents accommodated in the container body 2, and a tubular member 30 having an engaging portion (annular protrusion 31b) that engages with the outer surface of the mouth 4 below the stopper and restricts upward and radially outward displacement of the dispensing member 10 when the lower portion of the dispensing member 10 abuts against the top wall 83 of the stopper or the upper end of the mouth 4. With this configuration, the tubular member 30 that secures the dispensing member 10 engages with the mouth 4 via the engaging portion provided below the stopper, so that the tubular member 30 is supported by the stopper at least via the dispensing member 10 and also by the engaging portion. In particular, in the example shown in FIG. 1 , the outer peripheral wall 31 of the tubular member 30 is also supported by the side surface of the stopper. Therefore, when the cap is unused, the inclination of the cylindrical member 30 relative to the opening 4 can be suppressed, and the replacement cap 1 can be made less likely to come off the opening 4.

[0043] Next, a replacement cap 101 and a container 200 according to a second embodiment of the present disclosure will be described in detail. This embodiment is similar to the first embodiment in configuration except for the following: (1) the dispensing member 10 has an elastically deformable bottom wall 15 and a side wall 17 having an opening 17a instead of the flange portion 12; and (2) a holding protrusion 31d is provided at the lower end of the support rib 31c for holding the dispensing member 10 in the vertical direction. Therefore, differences from the first embodiment will be mainly described here. Furthermore, parts having the same functions as those of the first embodiment will be described using the same reference numerals.

[0044] The dispensing member 10 comprises a peripheral wall 11 having an outer diameter smaller than the inner diameter of the mouth portion 4, a top wall 13 on which a dispensing tube 14 is erected that closes the upper end of the peripheral wall 11 and forms a dispensing hole 14a on the upper surface, a bottom wall 15 (sealing portion) that protrudes radially outward from the lower end of the peripheral wall 11, a side wall 17 (sealing portion) that has an opening 17a that is provided to vertically connect the outer peripheral end of the bottom wall 15 and the top wall 13, and an outer tube wall 19 that is erected at the outer peripheral end of the top wall 13 and continues to a hinge portion 18. The outer diameters of the outer peripheral ends of the bottom wall 15 and side wall 17 are formed larger than the inner diameter of the mouth portion 4. When the dispensing member 10 is removed from the tubular member 30 and inserted inside the mouth portion 4 as described below, the outer peripheral end of the bottom wall 15 abuts against the inner peripheral surface of the mouth portion 4, thereby liquid-tightly sealing the storage space S of the container body 2 from the outside (see Figure 10).

[0045] As shown in FIG. 8, a support rib 31c is provided in a region of the outer peripheral wall 31 radially outward of the top wall 13, supporting the top wall 13 and the outer cylindrical wall 19 from the radially outward direction. The outer peripheral ends of the top wall 13 and the outer cylindrical wall 19 fit into the inner peripheral ends of this support rib 31c, thereby restricting radially outward displacement of the pouring member 10. In this embodiment, a holding protrusion 31d is provided at the lower end of the support rib 31c to hold the pouring member 10 in the up-down direction. As shown in FIG. 8, the outer peripheral ends of the top wall 13 and the outer cylindrical wall 19 engage with the holding protrusion 31d, thereby holding the pouring member 10 and the lid 20 above the holding protrusion 31d. Furthermore, the pouring member 10 is restricted from upward displacement by the upper wall 33 of the tubular member 30 via the lid 20.

[0046] As in the first embodiment, the replacement cap 101 has a pressing portion 33a at the radial center of the upper wall 33, which can be pressed downward.

[0047] When using a container 200 equipped with a replacement cap 101 having the above-described configuration, the user first breaks the weakened portion 31a from the state shown in Figure 8, thereby releasing the undercut engagement between the neck ring 4b and the annular protrusion 31b. This allows the user to remove the replacement cap 101 from the opening 4 of the container body 2 by moving it upward. Then, the stopper (crown cap 80) is removed.

[0048] Next, after placing the removed replacement cap 101 in a stable location such as on a desk, the user presses downward the pressing portion 33a of the tubular member 30 using the index finger or the like. This breaks the weakened portion 33b, and as shown in Figure 9, the dispensing member 10 and the lid body 20 are pressed downward by the pressing portion 33a that has rotated around the hinge portion 33c, and the engagement between the top wall 13 and the holding protrusion 31d is released, allowing them to be removed from the replacement cap 101.

[0049] The user attaches the dispensing member 10 and the lid 20 to the mouth 4 of the container body 2. When attaching the dispensing member 10, the lower end of the peripheral wall 11 is inserted into the mouth 4 from the upper opening of the mouth 4. At this time, the bottom wall 15 abuts against the mouth 4 because the outer diameter of the bottom wall 15 is larger than the inner diameter of the mouth 4. As shown in FIG. 10 , by pushing the dispensing member 10 downward while elastically deforming the outer peripheral edge of the bottom wall 15 so that it displaces upward, the dispensing member 10 can be attached to the mouth 4 with the bottom wall 15 liquid-tightly sealing the storage space S from the outside. Note that in this embodiment, the outer peripheral edge of the bottom wall 15 is connected to the top wall 13 by the side wall 17 having the opening 17a, which stabilizes the shape of the bottom wall 15. Therefore, the storage space S can be more stably sealed from the outside.

[0050] Next, a replacement cap 201 and a container 300 according to a third embodiment of the present disclosure will be described in detail. This embodiment is similar to the configuration of the first embodiment, except that, compared to the first embodiment, the cylindrical member 30 does not have an upper wall 33, but instead (1) an engaging claw 31e is provided at the upper end of the outer peripheral wall 31 to engage with the dispensing member 10, and (2) the dispensing member 10 includes an outer cylindrical wall 19 erected on the upper surface of the top wall 13b, and an abutting wall 19a extending radially outward from the upper end of the outer cylindrical wall 19 and against which the upper end of the outer peripheral wall 31 abuts. Therefore, the following description will focus on the differences from the first embodiment. Furthermore, parts having the same functions as those of the first embodiment will be described using the same reference numerals.

[0051] 11, the dispensing member 10 includes a peripheral wall 11 having an outer diameter smaller than the inner diameter of the mouth portion 4, top walls 13, 13b on which a dispensing tube 14 is erected that closes the upper end of the peripheral wall 11 and forms a dispensing hole 14a on its upper surface, a flange portion 12 (sealing portion) that protrudes radially outward from the peripheral wall 11 and has an outer diameter at its outer peripheral end larger than the inner diameter of the mouth portion 4, an outer tube wall 19 that is erected on the upper surface of the top wall 13b radially outside the dispensing tube 14, and an abutment wall 19a that extends further radially outward from the upper end of the outer tube wall 19 and is connected to the lid 20 via a hinge portion 18. When a replacement cap 201 is removed from the container body 2 and the peripheral wall 11 is inserted inside the mouth portion 4 as described below, the outer peripheral end of the flange portion 12 abuts against the inner peripheral surface of the mouth portion 4, thereby liquid-tightly sealing the storage space S of the container body 2 from the outside (see FIG. 12).

[0052] The tubular member 30 includes an outer peripheral wall 31 that surrounds the mouth portion 4 from the radial outside, an engaging claw 31e provided at the upper end of the outer peripheral wall 31, a weakened portion 31a that is provided in a region of the outer peripheral wall 31 radially outside the neck ring 4b and is thinner than other regions of the outer peripheral wall 31, and an annular protrusion 31b that is provided below the weakened portion 31a, protrudes radially inward, and engages with the neck ring 4b in an undercut manner.

[0053] Engagement claws 31e provided at the upper end of outer peripheral wall 31 engage with the outer peripheral edge of top wall 13b through undercuts, restricting upward displacement of dispensing member 10. Furthermore, the outer peripheral edge of top wall 13b fits into support rib 31c, thereby restricting radially outward displacement of dispensing member 10. In this embodiment, as shown in FIG. 11 etc., side wall 81 of crown 80 abuts against the inner peripheral surface of support rib 31c, thereby supporting outer peripheral wall 31 by side wall 81 of crown 80. The upper end of outer peripheral wall 31 abuts against the lower surface of abutment wall 19a.

[0054] When using a container 300 equipped with a replacement cap 201 having the above configuration, a user first breaks the weakened portion 31a from the state shown in FIG. 11 to release the undercut engagement between the neck ring 4b and the annular protrusion 31b. To release the undercut engagement, the user tears off the bridge portion 31g (shown in FIG. 13) located directly below the weakened portion 31a, and sequentially breaks the weakened portion 31a in the circumferential direction, thereby removing the area of ​​the tubular member 30 below the weakened portion 31a (see FIG. 14). Because the undercut engagement between the neck ring 4b and the annular protrusion 31b is released by breaking the weakened portion 31a, the user can remove the replacement cap 201 from the opening 4 of the container body 2 by moving it upward. Then, the stopper (crown cap 80) is removed.

[0055] The user attaches the removed replacement cap 201 to the mouth 4 of the container body 2. When attaching the dispensing member 10, the lower end of the peripheral wall 11 is inserted into the mouth 4 from the upper opening of the mouth 4. Because the outer diameter of the flange 12 is larger than the inner diameter of the mouth 4, the flange 12 abuts against the mouth 4. As shown in FIG. 12 , by pushing the dispensing member 10 downward while elastically deforming the outer peripheral end of the flange 12 so as to displace upward, the dispensing member 10 can be attached to the mouth 4 with the flange 12 liquid-tightly sealing the storage space S from the outside.

[0056] Next, a replacement cap 301 and a container 400 according to a fourth embodiment of the present disclosure will be described in detail. This embodiment is similar to the configuration of the third embodiment except for the following: (1) instead of forming an engagement claw 31e at the upper end of the outer peripheral wall 31, a fixed wall 37 extending radially inward from the upper end of the outer peripheral wall 31 and a fixed cylinder 37a hanging down from the inner peripheral side of the fixed wall 37 are provided; and (2) the lid 20 is integrally formed with the tubular member 30 via a hinge portion 18, rather than with the dispensing member 10. Therefore, the following description will focus on the differences from the third embodiment. Furthermore, parts having the same functions as those of the third embodiment will be described using the same reference numerals.

[0057] The cylindrical member 30 is provided with a fixed wall 37 extending radially inward from the upper end of the outer circumferential wall 31, and a fixed cylinder 37a hanging down from the inner circumferential side of the fixed wall 37. The inner circumferential end of the fixed wall 37 abuts against the outer circumferential end of the top wall 13 of the dispensing member 10, thereby restricting radially outward displacement of the dispensing member 10. Furthermore, the upper end of the peripheral wall 11 abuts against the lower surface at the inner circumferential end of the fixed wall 37, thereby restricting upward displacement of the dispensing member 10. The fixed cylinder 37a hangs down from the inner circumferential side of the fixed wall 37, and the outer surface of the peripheral wall 11 fits into the inner surface of the fixed cylinder 37a.

[0058] In this embodiment, the lid 20 is integrally formed with the upper end of the outer peripheral wall 31 of the cylindrical member 30 via a hinge portion 18 .

[0059] When using a container 400 equipped with a replacement cap 301 having the above configuration, a user first breaks the weakened portion 31a from the state shown in FIG. 15 to release the undercut engagement between the neck ring 4b and the annular protrusion 31b. To release the undercut engagement, as in the third embodiment, the bridge portion 31g located directly below the weakened portion 31a is torn off (see FIG. 13), and the weakened portion 31a is sequentially broken in the circumferential direction, thereby removing the region of the tubular member 30 below the weakened portion 31a (see FIG. 14). Since the undercut engagement between the neck ring 4b and the annular protrusion 31b is released by breaking the weakened portion 31a, the user can remove the replacement cap 301 from the opening 4 of the container body 2 by moving it upward. Then, the stopper (crown cap 80) is removed.

[0060] The user attaches the replacement cap 301 to the mouth 4 of the container body 2. When attaching the replacement cap 301, the user inserts the lower end of the peripheral wall 11 into the mouth 4 from the upper opening of the mouth 4. Because the outer diameter of the flange 12 is larger than the inner diameter of the mouth 4, the flange 12 abuts against the mouth 4. As shown in FIG. 16 , by pushing the replacement cap 301 downward while elastically deforming the outer peripheral end of the flange 12 so as to displace upward, the replacement cap 301 can be attached to the mouth 4 with the flange 12 liquid-tightly sealing the storage space S from the outside.

[0061] As described above, in this embodiment, the lid 20 that covers the pouring hole 14a is configured to be integrally formed with the cylindrical member 30. By adopting such a configuration, the number of parts and the number of assembly steps for the container 400 can be reduced.

[0062] Although the present disclosure has been described based on various drawings and examples, it should be noted that those skilled in the art can easily make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present invention. For example, the functions included in each component can be rearranged so as not to cause logical inconsistencies, and multiple components can be combined into one or divided. It should be understood that these modifications and alterations are also included in the scope of the present invention.

[0063] For example, in the first to fourth embodiments, the cylindrical member 30 is configured to restrict the upward and radially outward displacement of the dispensing member 10 when the lower part of the dispensing member 10 is in contact with the top wall 83 of the crown 80 (stopper), but this is not limited to this. The cylindrical member 30 may also be configured to restrict the upward and radially outward displacement of the dispensing member 10 when the lower part of the dispensing member 10 is in contact with the upper end of the spout 4.

[0064] In the first to fourth embodiments, the seal portion (the flange portion 12, or the bottom wall 15 and the side wall 17) protrudes radially outward from the peripheral wall 11, but the present invention is not limited to this. For example, the peripheral wall 11 may be configured to fit directly onto the inner surface of the mouth portion 4.

[0065] In the first to fourth embodiments, the cylindrical member 30 is configured to have the weakened portion 31a above the engaging portion (annular protrusion 31b), but this is not limited to this. The weakened portion 31a may not be provided.

[0066] In the first to fourth embodiments, the dispensing member 10 or the cylindrical member 30 and the lid 20 are configured to be integrally formed, but this is not limiting. The lid 20 may be configured as a separate part from the dispensing member 10 and the cylindrical member 30, or may be integrated with another member. [Explanation of symbols]
