Description

[Technical Field]

[0001] The present invention relates to a refillable container and a container with a lid. [Background technology]

[0002] BACKGROUND ART Conventionally, as shown in Patent Document 1 below, for example, containers with lids are known in which the contents stored therein can be taken out by removing the lid. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-121595 Summary of the Invention [Problem to be solved by the invention]

[0004] In a conventional container with a lid, when the remaining amount of contents becomes small, it is impossible to remove the contents without inserting a finger or a spatula deep into the container body.

[0005] An object of the present invention is to provide a refillable container and a container with a lid that allow the contents to be easily removed even when the remaining amount of the contents is low. [Means for solving the problem]

[0006] A refillable container according to one aspect of the present invention comprises a bottomed cylindrical inner tube housed inside a bottomed cylindrical container body so as to be rotatable in a circumferential direction around the container axis, and an inner plate fitted inside the inner tube so as to be slidable in the axial direction of the container while its circumferential rotation is restricted. The inner plate is formed with a countersunk screw cylinder extending downward, and the countersunk screw cylinder is screwed onto a container screw cylinder extending upward from the bottom wall of the container body. The inner tube is removably housed inside the container body, and the A center tube locking wall extending upward is formed on the bottom wall of the center tube, and a center plate locking wall extending downward and releasably engaged with the center tube locking wall to restrict upward movement is formed on the center plate.When the center tube is housed inside the container body, a release protrusion extending upward from the bottom wall of the container body presses the center tube locking wall in a direction away from the center plate locking wall, causing it to deform, thereby releasing the lock of the center plate locking wall by the center tube locking wall.

[0007] The container includes a center tube rotatably housed inside the container body, and a center plate fitted inside the center tube so as to be slidable in the container axial direction while its circumferential rotation is restricted. The center plate has a countersunk head screw barrel extending downward, which is threadedly attached to a container screw barrel extending upward from the bottom wall of the container body. Therefore, when the center tube and the center plate are rotated circumferentially relative to the container body, the countersunk head screw barrel rotates circumferentially relative to the container screw barrel, causing the center plate to rise relative to the center tube and the container body. This allows the contents on the center plate to be positioned near the upper end openings of the center tube and the container body regardless of the remaining amount. This allows the contents to be easily removed even when the remaining amount is low, and reduces the contact area of ​​the contents in the center tube with air. When the contents are used up and a new refill container is inserted into the container body, even if an upward force is applied from the container screw barrel to the center plate via the center plate screw barrel when the center plate locking wall is locked to the center cylinder locking wall, the center plate can be prevented from rising relative to the cylinder. This prevents the center plate from unintentionally rising relative to the cylinder when inserting a new refill container into the container body, which could cause the contents to overflow from the cylinder, for example. When a new refill container is accommodated inside the container body, the release protrusion on the container body presses the center cylinder locking wall in a direction away from the center plate locking wall, deforming the wall, thereby releasing the lock of the center plate locking wall by the center cylinder locking wall. Therefore, when a new refill container is accommodated inside the container body, the center plate can be raised relative to the center cylinder and the container body as the center countersunk screw tube and the container screw tube rotate relative to each other in the circumferential direction.

[0008] The outer surface of the middle plate may have a non-circular shape when viewed in cross section, and the portion of the inner surface of the middle cylinder along which the outer surface of the middle plate slides in the axial direction of the container may have a non-circular shape when viewed in cross section, and the outer surface of the middle plate may abut against the inner surface of the middle cylinder over its entire circumference.

[0009] The outer surface of the middle plate has a non-circular shape when viewed in cross section, and the portion of the inner surface of the middle cylinder along which the outer surface of the middle plate slides in the axial direction of the container also has a non-circular shape when viewed in cross section, and the outer surface of the middle plate abuts against the inner surface of the middle cylinder around its entire circumference.This makes it possible to easily and reliably achieve a configuration in which the middle plate is fitted inside the middle cylinder so that it can slide freely in the axial direction of the container while its circumferential rotational movement is restricted.

[0010] A lidded container according to one embodiment of the present invention comprises a refillable container of the present invention, the container body, a lid body removably screwed onto the container body, and a lid body having an inner stopper fitted inside the upper end of the middle tube, wherein the upper end of the middle tube has a circular shape in cross section and is rotatably fitted inside the upper end of the container body, and the middle tube rotates around the container axis relative to the container body together with the lid body due to frictional resistance between the middle tube and the inner stopper.

[0011] The inner cylinder rotates around the container axis relative to the container body together with the lid due to frictional resistance between the inner stopper and the cylinder, so that when the lid is attached to or detached from the container body, the inner plate can be raised relative to the inner cylinder. With the lid removed, the contents can always be positioned near the upper opening of the inner cylinder, making it easy to remove the contents.

[0012] An operation flange portion may be formed at the upper end of the middle cylinder, protruding radially outward and placed on the edge of the upper opening of the container body.

[0013] Since the upper end of the middle cylinder is formed with an operating flange that rests on the rim of the upper opening of the container body, by pinching the operating flange and rotating the middle cylinder circumferentially relative to the container body, the countersunk screw cylinder rotates circumferentially relative to the container screw cylinder, making it possible to adjust the position of the middle plate in the axial direction of the container. This makes it possible, for example, to operate the operating flange while the lid is removed and raise the middle plate so that the contents reach near the upper opening of the middle cylinder when a large amount of content on the middle plate has been used.

[0014] The countersunk head screw tube rises when rotated in one circumferential direction relative to the container screw tube, and a ratchet portion may be provided between the container body and the center tube, which allows the center tube to spin freely relative to the container body when the center tube rotates in one circumferential direction, and which regulates the relative rotation of the container body and the center tube when the center tube attempts to rotate in the other circumferential direction.

[0015] When the lid body is rotated in one circumferential direction relative to the container body, the middle cylinder rotates in this direction together with the middle plate, and at this time, the ratchet portion causes the middle cylinder to spin freely relative to the container body, and the middle plate screw cylinder rotates in one circumferential direction relative to the container screw cylinder, causing the middle plate to rise relative to the middle cylinder. When the lid body is rotated in the other circumferential direction relative to the container body, the middle cylinder rotates in this direction together with the middle plate, and at this time, the ratchet portion restricts the relative rotation between the container body and the middle cylinder, and only the lid body rotates in the other circumferential direction relative to the container body. As a result, when the lid body is attached or detached to the container body, the inner plate does not descend relative to the inner cylinder, and the inner plate can be reliably raised relative to the inner cylinder.When the lid body is removed, the contents can always be reliably positioned near the upper opening of the inner cylinder. [Effects of the Invention]

[0016] According to one aspect of the present invention, the contents can be easily removed even when the remaining amount of the contents is low. [Brief explanation of the drawings]

[0018] Hereinafter, a refillable container and a container with a lid according to one embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the lidded container 1 according to this embodiment comprises a refillable container 10, a container body 11, and a lid 12. The refill container 10 includes a center cylinder 13 and a center plate 14, and the lid body 12 includes a lid main body 15 and a center plug 16. The container main body 11 is formed in a cylindrical shape with a bottom, and the lid main body 15 is formed in a cylindrical shape with a top. The container body 11, the inner cylinder 13, the inner plate 14, the lid body 15, and the inner plug 16 are arranged coaxially on a common axis.

[0019] Hereinafter, the common axis will be referred to as the container axis O, the side of the lid body 12 along the container axis O will be referred to as the upper side, the side of the bottom wall 11a of the container body 11 along the container axis O will be referred to as the lower side, the direction along the container axis O will be referred to as the container axis O direction, the direction intersecting the container axis O when viewed from the container axis O direction will be referred to as the radial direction, and the direction circumferential around the container axis O when viewed from the container axis O direction will be referred to as the circumferential direction.

[0020] The portion of the peripheral wall 11b of the container body 11 located below the upper end is formed in a double cylindrical shape. The upper end of the peripheral wall 11b has a circular shape in cross section. A male thread portion is formed on the outer circumferential surface of the upper end of the peripheral wall 11b. A container screw cylinder 17, a release protrusion 18, and a ratchet gear 19 are formed on the bottom wall 11a of the container body 11. The container screw cylinder 17 and the ratchet gear 19 are formed in a cylindrical shape extending upward from the bottom wall 11a, and are disposed coaxially with the container axis O.

[0021] A male thread is formed on the outer circumferential surface of the container screw cylinder 17 . The ratchet gear 19 surrounds the container screw barrel 17 from the radial outside. The upper end of the ratchet gear 19 is located below the upper end of the container screw barrel 17. As shown in Fig. 5, of the teeth formed on the outer peripheral surface of the ratchet gear 19, the surface facing one circumferential side T1 extends radially when viewed from the container axis O direction, and the surface facing the other circumferential side T2 extends radially inward from one circumferential side T1 toward the other circumferential side T2 when viewed from the container axis O direction. A plurality of release protrusions 18 are provided at intervals in the circumferential direction on the upper surface of the bottom wall 11a of the container body 11 in a portion located radially outward from the ratchet gear 19. Each release protrusion 18 is formed in the shape of a plate with its front and back surfaces facing radially. A reinforcing rib 18a connected to the upper surface of the bottom wall 11a of the container body 11 is formed on the outer surface of each release protrusion 18.

[0022] The center cylinder 13 is housed inside the container body 11 so as to be rotatable in the circumferential direction. The center cylinder 13 is housed inside the container body 11 so as to be removably housed inside the container body 11. The center cylinder 13 is formed in a bottomed cylindrical shape having a bottom wall 13a. The bottom wall 13a is formed in an annular shape.

[0023] The upper end of the peripheral wall 13b of the center cylinder 13 has a circular shape in cross section and is rotatably fitted inside the upper end of the peripheral wall 11b of the container body 11. The inner peripheral surface of the peripheral wall 13b of the center cylinder 13, where the outer peripheral surface of the center plate 14 slides in the direction of the container axis O, has a non-circular shape (an elliptical shape in the illustrated example) in cross section. An operation flange portion 21 is formed at the upper end of the peripheral wall 13b of the center cylinder 13, protruding radially outward and resting on the upper opening edge of the peripheral wall 11b of the container body 11. An outer fitting cylinder 21a is formed at the radially outer end of the operation flange portion 21, extending downward and fitted externally to the upper end of the peripheral wall 11b of the container body 11. An anti-slip uneven portion is formed around the entire outer peripheral surface of the outer fitting cylinder 21a.

[0024] A center tube locking wall 22 extending upward is formed on the bottom wall 13a of the center tube 13. As shown in Figure 6, a plurality of center tube locking walls 22 are provided at intervals in the circumferential direction. The center tube locking wall 22 is formed in a plate shape with the front and back surfaces facing in the radial direction. A locking protrusion that protrudes radially outward is formed on the outer surface of the upper end of the center tube locking wall 22. The center tube locking wall 22 is formed to be flexible and deformable in the radial direction.

[0025] A plurality of through holes 22a are formed in the bottom wall 13a of the center tube 13 at intervals in the circumferential direction, and the center tube locking wall 22 extends upward from the radially inner end of the opening periphery of the through holes 22a in the bottom wall 13a. The release protrusions 18 are inserted into the through holes 22a. The outer surface of the center tube locking wall 22 is pressed radially inward by the inner surface of the release protrusions 18, and the center tube locking wall 22 is deflected and deformed radially inward.

[0026] A cantilever-shaped ratchet pawl 23 is formed on the inner peripheral surface of the bottom wall 13a of the center cylinder 13. The ratchet pawl 23 has a fixed end at one circumferential side T1 and a free end at the other circumferential side T2. The ratchet pawl 23 is formed to be flexible and deformable on both sides in the radial direction. A plurality of ratchet pawls 23 are provided at intervals in the circumferential direction. When the middle tube 13 rotates toward one circumferential side T1 relative to the container body 11, the ratchet pawl portion 23 moves toward one circumferential side T1 while sliding against the tooth portion of the ratchet gear 19, causing the middle tube 13 to rotate freely relative to the container body 11.When the middle tube 13 attempts to rotate toward the other circumferential side T2 relative to the container body 11, the end face of the other circumferential side T2 of the ratchet pawl portion 23 abuts against the surface of the tooth portion of the ratchet gear 19 facing the one circumferential side T1, thereby restricting the relative rotation between the middle tube 13 and the container body 11. As a result, the ratchet claw portion 23 and the ratchet gear 19 are located between the container body 11 and the middle tube 13, and form a ratchet portion that allows the middle tube 13 to spin freely relative to the container body 11 when the middle tube 13 rotates to one side T1 in the circumferential direction, and that regulates the relative rotation of the container body 11 and the middle tube 13 when the middle tube 13 attempts to rotate to the other side T2 in the circumferential direction.

[0027] The lid body 15 of the lid 12 is detachably screwed onto the container body 11. An internal thread is formed on the inner peripheral surface of the lid body 15 to be threadedly engaged with an external thread formed on the upper end of the peripheral wall 11b of the container body 11. The lid body 12 rises when rotated toward the other circumferential side T2 relative to the container body 11, and falls when rotated toward the one circumferential side T1. The inner plug 16 of the lid body 12 extends downward from the top wall of the lid main body 15 and is fitted inside the upper end of the peripheral wall 13b of the middle cylinder 13. Due to frictional resistance between the outer peripheral surface of the inner plug 16 and the inner peripheral surface of the peripheral wall 13b of the middle cylinder 13, the lid body 12 and the middle cylinder 13 can rotate around the container axis O relative to the container main body 11.

[0028] The inner plate 14 is fitted inside the inner tube 13 so as to be slidable in the direction of the container axis O while its rotational movement in the circumferential direction is restricted. The inner plate 14 is formed in a cylindrical shape with a top. The outer peripheral surface of the inner plate 14 is non-circular in cross section and abuts against the inner peripheral surface of the inner tube 13 over the entire circumference. A inner plate screw cylinder 24 and an inner plate locking wall 25 are formed on the top wall of the inner plate 14.

[0029] The countersunk screw tube 24 extends downward from the top wall of the center plate 14 and is threadedly attached to the container screw tube 17. The countersunk screw tube 24 is disposed coaxially with the container axis O. An internal thread portion that threads onto the external thread portion of the container screw tube 17 is formed on the inner peripheral surface of the countersunk screw tube 24. The countersunk screw tube 24 rises when rotated to one circumferential side T1 relative to the container screw tube 17, and if the ratchet portion described above were not present, it would descend when rotated to the other circumferential side T2.

[0030] The inner plate locking wall 25 extends downward from a portion of the top wall of the inner plate 14 that is located radially outward from the inner plate screw cylinder 24. The inner plate locking wall 25 is formed in a cylindrical shape that extends in the direction of the container axis O, and is disposed coaxially with the container axis O. A locking protrusion that protrudes radially inward is formed on the inner peripheral surface of the inner plate locking wall 25.

[0031] 4, before the center cylinder 13 is housed inside the container body 11, the locking protrusions of the center plate locking wall 25 are undercut-fitted to the locking protrusions of the center cylinder locking wall 22, and the center plate locking wall 25 is releasably locked to the center cylinder locking wall 22, restricting upward movement of the center plate 14 relative to the center cylinder 13. In the illustrated example, the inner surface of the center plate locking wall 25 abuts against the outer surface of the center cylinder locking wall 22. When the center cylinder 13 is housed inside the container body 11, the release protrusion 18 of the container body 11 is inserted into the through-hole 22a, and the release protrusion 18 presses the center cylinder locking wall 22 in a direction away from the center plate locking wall 25 in the radial direction, deforming the wall, thereby releasing the lock of the center plate locking wall 25 by the center cylinder locking wall 22. This allows the center plate 14 to move upward relative to the center cylinder 13. In the illustrated example, the inner surface of the release protrusion 18 presses the outer surface of the center cylinder locking wall 22 radially inward. In addition, the outer surface of the inner plate locking wall 25 may abut against the inner surface of the inner tube locking wall 22, and the outer surface of the release protrusion 18 may press the inner surface of the inner tube locking wall 22 radially outward.

[0032] Next, how to use the container with lid 1 will be described.

[0033] When the lid body 12 is rotated toward the other circumferential side T2 relative to the container body 11, the lid body 12 rises relative to the container body 11. At this time, due to frictional resistance between the outer peripheral surface of the inner plug 16 of the lid body 12 and the inner peripheral surface of the peripheral wall 13b of the center cylinder 13, the center cylinder 13 also tries to rotate together with the lid body 12 about the container axis O relative to the container body 11. However, the end face of the other circumferential side T2 of the ratchet pawl portion 23 of the center cylinder 13 abuts against the surface of the tooth portion of the ratchet gear 19 facing the one circumferential side T1, thereby restricting the relative rotation of the center cylinder 13 and the container body 11. As a result, only the lid body 12 rotates toward the other circumferential side T2 relative to the container body 11 and detaches from the container body 11, opening the inside of the center cylinder 13 and allowing the contents on the center plate 14 to be removed with fingers, a spatula, or the like.

[0034] Subsequently, in the process of rotating the lid 12 toward one circumferential side T1 relative to the container body 11 to attach the lid 12 to the upper end of the peripheral wall 11b of the container body 11, the outer peripheral surface of the inner plug 16 of the lid 12 abuts against the inner peripheral surface of the peripheral wall 13b of the inner cylinder 13, causing the inner cylinder 13 to rotate together with the lid 12 around the container axis O relative to the container body 11. At this time, the ratchet pawl 23 of the inner cylinder 13 bends and deforms radially and moves toward one circumferential side T1 while sliding against the teeth of the ratchet gear 19, causing the inner cylinder 13 to rotate freely relative to the container body 11. As a result, the inner plate 14, which is fitted inside the inner cylinder 13 with its circumferential rotation restricted, also rotates toward one circumferential side T1 relative to the container body 11. As a result, the inner plate screw tube 24 rotates toward one circumferential side T1 relative to the container screw tube 17, causing the contents on the inner plate 14 to rise.

[0035] Here, if you want to remove additional contents after removing the lid body 12 from the container body 11 and removing the contents, you can leave the lid body 12 removed from the container body 11 and rotate the operating flange portion 21 to one circumferential side T1 relative to the container body 11, thereby raising the contents on the inner plate 14 and bringing them closer to the upper end opening of the inner tube 13.

[0036] After the contents contained in the inner tube 13 have been used up, the inner tube 13 is lifted up relative to the container body 11 by pinching the operating flange portion 21, and then a new refill container 10 filled with the contents is placed inside the container body 11. At this time, the refill container 10 is pushed into the container body 11 in the direction of the container axis O, the inner countersunk screw tube 24 is fitted onto the container screw tube 17, and the release protrusion 18 of the container body 11 is inserted into the through hole 22a in the bottom wall 13a of the inner tube 13. During this process, until the center cylinder locking wall 22 abuts against the release projection 18, the locking projection of the center plate locking wall 25 is undercut-fitted with the locking projection of the center cylinder locking wall 22, restricting the upward movement of the center plate 14 relative to the center cylinder 13. When the center cylinder locking wall 22 abuts against the release projection 18, the center cylinder locking wall 22 is pressed by the release projection 18 in a direction radially away from the center plate locking wall 25, causing it to bend and deform, thereby releasing the lock of the center plate locking wall 25 by the center cylinder locking wall 22. This allows the center plate 14 to move upward relative to the center cylinder 13.

[0037] As described above, the refill container 10 according to this embodiment comprises a middle tube 13 that is accommodated inside the container body 11 so as to be freely rotatable in the circumferential direction, and a middle plate 14 that is fitted inside the middle tube 13 so as to be freely slidable in the direction of the container axis O while its circumferential rotational movement is restricted. The middle plate 14 has a middle countersunk screw tube 24 that extends downward, and the middle countersunk screw tube 24 is screwed into a container screw tube 17 that extends upward from the bottom wall 11a of the container body 11. Therefore, when the inner cylinder 13 is rotated circumferentially relative to the container body 11 together with the inner plate 14, the inner plate screw tube 24 rotates circumferentially relative to the container screw tube 17, causing the inner plate 14 to rise relative to the inner cylinder 13 and the container body 11. This makes it possible to position the contents on the inner plate 14 near the upper end openings of the inner cylinder 13 and the container body 11 regardless of the remaining amount, making it easy to remove the contents even when the remaining amount is low, and also reducing the contact area of ​​the contents in the inner cylinder 13 with the air.

[0038] After the contents have been used up, in the process of accommodating a new refill container 10 into the container body 11, when the container screw tube 17 is fitted with the countersunk screw tube 24, an upward thrust is applied to the inner plate 14 from the container screw tube 17 via the countersunk screw tube 24. However, since the inner plate locking wall 25 is locked to the middle tube locking wall 22, it is possible to prevent the inner plate 14 from rising unintentionally relative to the middle tube 13 when accommodating a new refill container 10 into the container body 11, which can prevent the contents from spilling out of the middle tube 13, for example.

[0039] When a new refill container 10 is accommodated inside the container body 11, the release protrusion 18 of the container body 11 presses the center cylinder locking wall 22 in a direction away from the center plate locking wall 25 in the radial direction, causing it to deform, thereby releasing the lock of the center plate locking wall 25 by the center cylinder locking wall 22. Therefore, when a new refill container 10 is accommodated inside the container body 11, the center plate 14 can be raised relative to the center cylinder 13 and the container body 11 as the center countersunk screw tube 24 and the container screw tube 17 rotate relative to each other in the circumferential direction.

[0040] The outer surface of the middle plate 14 has a non-circular shape when viewed in cross section, and the portion of the inner surface of the middle tube 13 along which the outer surface of the middle plate 14 slides in the direction of the container axis O also has a non-circular shape when viewed in cross section, and the outer surface of the middle plate 14 abuts against the inner surface of the middle tube 13 over the entire circumference.This makes it possible to easily and reliably realize a configuration in which the middle plate 14 is fitted inside the middle tube 13 so that it can slide freely in the direction of the container axis O while its circumferential rotational movement is restricted.

[0041] The inner cylinder 13 rotates around the container axis O relative to the container body 11 together with the lid body 12 due to the frictional resistance between it and the inner stopper 16, so that when the lid body 12 is attached to or detached from the container body 11, the inner plate 14 can be raised relative to the inner cylinder 13. With the lid body 12 removed, the contents can always be positioned near the upper end opening of the inner cylinder 13, making it easy to remove the contents.

[0042] An operating flange 21 placed on the edge of the upper opening of the container body 11 is formed at the upper end of the middle cylinder 13, so that by rotating the middle cylinder 13 circumferentially relative to the container body 11, for example by pinching the operating flange 21, the middle countersunk screw cylinder 24 rotates circumferentially relative to the container screw cylinder 17, making it possible to adjust the position of the middle plate 14 in the direction of the container axis O. As a result, for example, when a large amount of content on the middle plate 14 is used with the lid 12 removed, the operating flange 21 can be operated with the lid 12 removed to raise the middle plate 14 and allow the content to reach the vicinity of the upper opening of the middle cylinder 13.

[0043] When the lid body 12 is rotated to one side T1 in the circumferential direction relative to the container body 11, the middle tube 13 rotates in this direction together with the middle plate 14, and at this time, the ratchet claw portion 23 and the ratchet gear 19 cause the middle tube 13 to spin freely relative to the container body 11, and the middle plate screw tube 24 rotates to one side T1 in the circumferential direction relative to the container screw tube 17, causing the middle plate 14 to rise relative to the middle tube 13. When the lid body 12 is rotated toward the other circumferential side T2 relative to the container body 11, the middle tube 13 rotates in this direction together with the middle plate 14, and at this time, the ratchet claw portion 23 and the ratchet gear 19 restrict the relative rotation of the container body 11 and the middle tube 13, and only the lid body 12 rotates toward the other circumferential side T2 relative to the container body 11. As a result, when the lid body 12 is attached to or detached from the container body 11, the inner plate 14 does not descend relative to the inner cylinder 13, and the inner plate 14 can be reliably raised relative to the inner cylinder 13. With the lid body 12 removed, the contents can always be reliably positioned near the upper opening of the inner cylinder 13.

[0044] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0045] For example, the lid 12 may come off from the container body 11 when rotated relative to the container body 11 to one side T1 in the circumferential direction. The lid body 15 and the inside plug 16 may be formed as separate bodies, or may be formed from different materials. The outer peripheral surface of the middle plate 14 and the inner peripheral surface of the middle tube 13 may each be formed to have a perfectly circular shape when viewed in cross section, and the outer peripheral surface of the middle plate 14 and the inner peripheral surface of the middle tube 13 may each be formed with uneven portions that engage with each other to regulate relative rotation in the circumferential direction. The operation flange portion 21 does not have to be formed at the upper end of the middle cylinder 13, and the operation flange portion 21 does not have to be formed with the outer fitting cylinder 21a. It is not necessary to provide a ratchet portion between the container body 11 and the inner cylinder 13. The configuration of the ratchet portion is not limited to the ratchet pawl portion 23 and the ratchet gear 19, and may be changed as appropriate.

[0046] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
