Abstract
Description
[Technical Field]
[0001] The present invention relates to a container with a lid. [Background technology]
[0002] Conventionally, there have been known lidded containers from which the contents can be removed by removing the attached lid, as shown in, for example, the following Patent Document 1. Patent Document 1 shows, as a lidded container, a wide-mouthed jar suitable for storing gel-like or cream-like contents. [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 this type of container with a lid, when the contents stored therein decrease, the user must insert a finger or a spatula deep into the container to remove the contents. In other words, this type of container with a lid is difficult to use in the latter half of use, and there is room for improvement.
[0005] An object of the present invention is to provide a container with a lid that allows easy removal of contents even when the contents are running low. [Means for solving the problem]
[0006] A lidded container according to one aspect of the present invention comprises a container body, a middle cylinder accommodated in the container body so as to be rotatable in a rotational direction around the container axis, a middle plate fitted to the inner surface of the middle cylinder so as to be slidable in the container axial direction, a lid body threaded onto the container body, and a lid having a middle stopper fitted to the inner surface of the upper end of the middle cylinder, wherein the outer peripheral surface of the middle plate has a non-circular shape in cross section, a portion of the inner surface of the middle cylinder along which the outer peripheral surface of the middle plate slides in the container axial direction has a non-circular shape in cross section, the outer peripheral surface of the middle plate abuts against the inner surface of the middle cylinder over the entire circumference, an upper end of the outer surface of the middle cylinder has a circular shape in cross section and is rotatably held within the upper end of the container body, and The inner tube rotates around the container axis together with the lid body due to frictional resistance between it and the inner stopper, and a lifting mechanism is provided between the container body and the inner plate which lifts the inner plate relative to the container body when the inner plate rotates in a first direction (tightening direction T1) of the rotation directions, and a ratchet portion is provided between the container body and the inner tube which causes the inner tube to spin freely relative to the container body when the inner tube rotates together with the inner plate in the first direction, and which regulates the relative rotation of the container body and the inner tube when the inner tube attempts to rotate together with the inner plate in a second direction (loosening direction T2) of the rotation directions which is opposite to the first direction.
[0007] When the lid is rotated in a second direction relative to the container body, rotation of the inner tube in the second direction is restricted. When the lid is rotated in a first direction, the inner stopper of the lid engages with the inner surface of the inner tube, causing the inner tube to rotate together with the inner stopper of the lid due to frictional resistance. Because the inner tube and inner plate, which are non-circular in cross section, are in contact with each other along their entire circumference, when the lid is rotated in the first direction, rotating the inner plate together with the inner tube, the inner plate rises relative to the container body. In other words, the contents contained in the storage space defined between the inner tube and inner plate rise each time the lid is attached to the container body, keeping the contents always above the container. This allows for easy removal of the contents even when they are low, improving usability.
[0008] When the inner cylinder rotates in the second direction relative to the container body, the ratchet portion restricts the rotation of the inner cylinder, and the inner plate does not rotate either, so the inner plate does not rise. On the other hand, when the inner cylinder rotates in the first direction relative to the container body, the ratchet portion causes the inner cylinder to spin freely, allowing the inner cylinder to rotate in the second direction. In this way, by providing the ratchet portion on the inner cylinder and inner plate, rotation in the second direction of the lid body can be easily restricted.
[0009] Furthermore, since rotation of the inner cylinder in the second direction is restricted, it is possible to prevent the inner plate from descending in the opposite direction so as to move away from the upper end of the container body. Furthermore, since the contents are held at the top of the container, the surface area of the contents that comes into contact with the outside air can be kept small, which prevents the contents from deteriorating due to the increased surface area that comes into contact with the outside air later in use.
[0010] The inside plug may be separate from the lid body, and the lid body and the inside plug may be formed from different materials.
[0011] By using only the inner plug from a different material from the lid body, for example, a material that can exert frictional resistance, the fit between the inner surface of the inner cylinder and the inner plug can be improved, and the inner cylinder can be rotated reliably along with the rotation of the lid body.
[0012] The inner plug may be provided with a separate friction resistance member between it and the middle cylinder.
[0013] Since a separate friction resistance member capable of exerting friction resistance is interposed between the inner plug and the inner cylinder, the inner plug can be fitted well with the inner surface of the inner cylinder, and the inner cylinder can be rotated reliably along with the rotation of the lid body.
[0014] A window may be provided on a side surface of the container body, and the center cylinder may be made of a light-transmitting material.
[0015] The position of the inner tray and the remaining amount of contents can be visually confirmed through the transparent inner cylinder through the window in the container body. [Effects of the Invention]
[0016] According to the above aspect of the present invention, even if the stored contents decrease, they can be easily removed. [Brief explanation of the drawings]

[Figure 6] FIG. 2 is a half side view of the container with lid showing the window portion of the container body. DETAILED DESCRIPTION OF THE INVENTION
[0018] Hereinafter, a container with a lid according to one embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 to 5, the lidded container 1 of this embodiment comprises a container body 2, a middle tube 3 that is rotatably accommodated in the container body 2 in a rotational direction around the container axis O, a middle plate 4 that is fitted onto the inner surface of the middle tube 3 so as to be slidable in the direction of the container axis O, and a lid body 5 that has a lid body main body 51 that is screwed onto the container body 2 and a middle stopper 52 that fits onto the inner surface of the upper end 3a of the middle tube 3.
[0019] The container body 2, center cylinder 3, center tray 4, and lid 5 are arranged with their respective central axes positioned on a common axis. Hereinafter, this common axis will be referred to as the container axis O, with the side of the lid 5 along the container axis O being referred to as the upper side and the opposite side being referred to as the lower side. Furthermore, in a plan view from the direction of the container axis O, the direction perpendicular to the container axis O will be referred to as the radial direction, and the direction going around the container axis O will be referred to as the circumferential direction. Furthermore, as shown in FIG. 2, among the circumferential directions, the clockwise direction when viewed from above is referred to as the tightening direction T1 (first direction), and the opposite direction, that is, the counterclockwise direction, is referred to as the loosening direction T2 (second direction) for opening the lid body 5.
[0020] 1 and 3 show a state in which the inner tray 4 is positioned downward, and FIG. 5 shows a state in which the inner tray 4 is positioned upward.
[0021] 1 and 3, the container body 2 includes a mouth 20, an inner peripheral wall 21 extending downward from the mouth 20, a disk-shaped bottom wall 22 connected to the lower end of the inner peripheral wall 21 and extending horizontally, and a cylindrical outer peripheral wall 23 opening downward from the mouth 20 via a shoulder 24. The inner shape of the inner peripheral wall 21 is circular in cross section, with the inner diameter slightly reduced at the lower end. The mouth 20 is formed to protrude upward from the radially inner end of the shoulder 24.
[0022] A male thread portion 20a is provided on the upper part of the mouth portion 20. The male thread portion 20a is threadedly engaged with a female thread portion 5a (described later) provided on the lid body 5. The male thread portion 20a and the female thread portion 5a are right-handed threads, and when the lid body 5 is rotated clockwise (tightening direction T1) in a plan view as shown in FIG. 2 relative to the container body 2, the female thread portion 5a is tightened relative to the male thread portion 20a, and when the lid body 5 is rotated counterclockwise (loosening direction T2), the female thread portion 5a is loosened relative to the male thread portion 20a.
[0023] 1, a claw-shaped locking portion 20b that protrudes radially inward is formed at the lower end of the mouth portion 20. The locking portion 20b restricts vertical movement relative to the middle cylinder 3 and also locks it so that it can rotate.
[0024] As shown in Figure 6, the inner peripheral wall 21 (side surface) and the outer peripheral wall 23 (side surface) of the container body 2 are provided with windows 28 that communicate with each other. In Figure 6, the right side of the container axis O shows the state before the inner tray 4 is raised (a state corresponding to Figure 1), and the left side shows the state after the inner tray 4 has been raised (a state corresponding to Figure 5). In the illustrated example, the windows 28 are formed vertically elongated across the inner peripheral wall 21 (side surface) and the outer peripheral wall 23 in the up-down direction. Note that the shape and number of the windows 28 are not limited to this, and multiple windows may be formed at intervals in the circumferential direction, for example.
[0025] 1 and 3, a cylindrical male screw shaft 25 (elevating mechanism) that rises upward is provided on the top surface at the center of the bottom wall portion 22. A male screw shaft 25 for elevation is provided on the upper end of the outer circumferential surface of the male screw shaft 25. The male screw shaft 25 for elevation has a male screw portion 25a formed thereon. The male screw portion 25a for elevation is threadedly engaged with a female screw portion 42a for elevation, which will be described later, that is provided on the inner tray 4. The male screw portion 25a for elevation and the female screw portion 42a for elevation are left-handed screws, and by rotating the lid body 5 together with the inner tube 3 clockwise in a plan view (tightening direction T1) as shown in FIG. 2 relative to the container body 2, the female screw portion 42a for elevation rotates relative to the male screw portion 25a for elevation, and the inner tray 4 moves upward. Furthermore, when the lid body 5 is rotated counterclockwise (loosening direction T2) in a planar view relative to the container body 2, as will be described in detail later, the rotation of the middle tube 3 in the loosening direction T2 is restricted, so the ascending female screw portion 42a does not rotate relative to the ascending male screw portion 25a, and the movement of the middle plate 4 in the vertical direction is restricted.
[0026] Additionally, a cylindrical outer cylindrical wall 26 is provided on the upper surface of the bottom wall portion 22, radially outward of the male screw shaft 25, and extends upward. The outer cylindrical wall 26 is lower than the male screw shaft 25. A plurality of claw-shaped anti-rotation protrusions 27 (ratchet portions) are formed on the outer peripheral surface of the outer cylindrical wall 26 at intervals along the circumferential direction, protruding radially outward in the vertical direction. As shown in FIGS. 2 and 3 , these anti-rotation protrusions 27 are formed so as to protrude radially outward as they extend in the fastening direction T1, and have locking surfaces 27a facing the fastening direction T1. These anti-rotation protrusions 27 are circumferentially engaged with engaging portions 33a of multiple elastic beams 33 of the inner cylinder 3, which will be described later. This restricts rotation of the inner cylinder 3 around the container axis O.
[0027] As shown in Figures 1, 3, and 5, the upper end 3a of the inner cylinder 3 is in contact between the container body 2 and the lid body 5 when the lid body 5 is closed. The outer upper end 3a of the inner cylinder 3 has a circular shape in cross section, and is rotatably held within the upper end of the container body 2. The inner cylinder 3 rotates together with the lid body 5 around the container axis O due to frictional resistance between the inner cylinder 3 and the inner stopper 52. The inner cylinder 3 is made of a light-transmitting material.
[0028] The inner surface of the center cylinder 3, excluding the upper end 3a, where the outer peripheral surface of the center plate 4 slides in the direction of the container axis O, has a non-circular shape (here, an ellipse) in cross section. The center cylinder 3 has a cylindrical peripheral wall 30, a protruding edge 31 that protrudes radially outward from the upper end 3a of the peripheral wall 30 so as to cover the upper end of the mouth 20 from above, and a center cylinder bottom 32 that extends radially inward from the lower end of the peripheral wall 30. The center cylinder bottom 32 is located above a portion of the bottom wall 22 of the container body 2 that is radially outward from the outer cylindrical wall 26. The inner edge of the center cylinder bottom 32 faces a rotation prevention protrusion on the outer cylindrical wall 26 of the bottom wall 22.
[0029] A recessed groove 30b that engages with the locking portion 20b of the container body 2 is formed on the outer peripheral surface of the peripheral wall portion 30. The recessed groove 30b extends around the entire circumferential direction. The locking portion 20b engages with the recessed groove 30b, so that the middle cylinder 3 is rotatably held relative to the container body 2.
[0030] 2 and 4, the rotation of the inner cylinder 3 in the loosening direction T2 of the lid 5 (see FIG. 1) is restricted. A ratchet portion (anti-rotation protrusion 27 and an elastic beam 33, described later) is provided between the container body 2 and the inner cylinder 3. The ratchet portion causes the inner cylinder 3 to rotate freely relative to the container body 2 when the inner cylinder 3 rotates together with the inner plate 4 in the tightening direction T1, and restricts the relative rotation of the container body 2 and the inner cylinder 3 when the inner cylinder 3 attempts to rotate together with the inner plate 4 in the loosening direction T2.
[0031] A recess 32a is provided on the inner edge of the middle tube bottom 32. The recess 32a is rectangular in plan view, and multiple recesses 32a (two in this embodiment) are provided at intervals in the circumferential direction. On the inner edge of the middle tube bottom 32, an elastic beam 33 (ratchet portion) is provided, one end (base end 33b) of which is connected to the outer edge of the recess 32a and the other end is a free end, and which is elastically deformable in the radial direction with the base end 33b as a fulcrum. The elastic beam 33 is formed in the shape of an elastically deformable band that is wide in the vertical direction.
[0032] The other end of the elastic beam 33 forms an engagement portion 33a that protrudes radially inward. Two elastic beams 33 are provided, spaced apart circumferentially. The elastic beams 33 have a curved surface that curves radially inward from the base end 33b toward the fastening direction T1. The pair of elastic beams 33 are arranged facing each other radially across the container axis O. When the inner tube 3 rotates in the loosening direction T2 relative to the container body 2, the engagement portion 33a of the elastic beam 33 engages with the anti-rotation protrusion 27. When the inner tube 3 rotates in the fastening direction T1 relative to the container body 2, the engagement portion 33a elastically deforms radially outward when it approaches the anti-rotation protrusion 27, overcomes the anti-rotation protrusion 27, and rotates freely relative to the anti-rotation protrusion 27, allowing the inner tube 3 to rotate in the fastening direction T1. This allows the inner tube 3 to rotate in the fastening direction T1. This allows the ratchet mechanism to function as described above.
[0033] 1, 3, and 5, the inner plate 4 is held in an anti-rotation manner relative to the inner cylinder 3. The outer peripheral surface of the inner plate 4 has a non-circular shape (here, an elliptical shape) in cross section, the same shape as the inner surface of the peripheral wall portion 30 of the inner cylinder 3, and abuts against the inner surface of the inner cylinder 3 over the entire circumference, thereby fitting to the inner cylinder 3 in an anti-rotation manner. The inner plate 4 is provided so as to be movable in the direction of the container axis O relative to the inner surface of the inner cylinder 3. The inner plate 4 is threadedly attached to the male screw shaft 25 in a state where it is slidably fitted into the inner cylinder 3 provided in the container body 2, and is movable up and down within the inner cylinder 3 as the male screw shaft 25 rotates. In this case, the inner plate 4 is threadedly attached to the male screw shaft 25 so that it moves upward when the male screw shaft 25 rotates in the fastening direction T1. In other words, an elevation mechanism is provided between the container body 2 and the inner plate 4, which elevates the inner plate 4 relative to the container body 2 when the inner plate 4 rotates in the fastening direction T1.
[0034] The inner tray 4 is located above the bottom wall portion 22. The inner tray 4 extends horizontally radially outward from the container axis O, and then extends downward in an arc. That is, the inner tray 4 includes a partition plate 40, a sliding cylindrical portion 41, and a threaded cylindrical portion 42 (elevating mechanism). The partition plate 40 connects the sliding cylindrical portion 41 and the threaded cylindrical portion 42 around the entire circumference, and confines the contents above the inner tray 4 within the container body 2.
[0035] The partition plate 40 has a radially inner end connected to the upper end of the threaded cylindrical portion 42 over its entire circumference, and a radially outer end connected to the upper part of the sliding cylindrical portion 41 over its entire circumference. When the inner plate 4 reaches its uppermost position, the partition plate 40 is positioned in sliding contact with the elliptical portion of the peripheral wall portion 30 of the inner cylinder 3.
[0036] The sliding cylindrical portion 41 is provided on the outer edge of the center plate 4 and extends upward and downward. The sliding cylindrical portion 41 is flexible and deformable radially inward, and is in sliding contact with the inner circumferential surface 30a of the peripheral wall portion 30 of the center cylinder 3. The sliding cylindrical portion 41 is in sliding contact over the entire circumference with the inner circumferential surface 30a of the peripheral wall portion 30 of the center cylinder 3, which has a non-circular cross-sectional shape such as an ellipse. As a result, the sliding cylindrical portion 41 is prevented from rotating by the inner circumferential surface 30a of the center cylinder 3, and is movable up and down by rotation of the threaded cylindrical portion 42 while being guided by the inner circumferential surface 30a of the center cylinder 3. The outer peripheral surface of the sliding contact cylindrical portion 41 is slightly recessed radially inward at the vertical middle portion, and the upper and lower ends are in sliding contact with the inner peripheral surface 30 a of the peripheral wall portion 30 .
[0037] Here, the storage space S surrounded by the inner tray 4, the sliding contact cylindrical portion 41 and the peripheral wall portion 30 stores contents such as gel or cream.
[0038] The threaded tube portion 42 is provided on the underside of the center of the inner plate 4 and has a cylindrical shape extending downward. The inner peripheral surface of the threaded tube portion 42 is provided with an ascending female thread portion 42a that screws into the ascending male thread portion 25a. The ascending female thread portion 42a is a left-handed thread. By rotating the lid body 5 together with the inner plate 3 clockwise in plan view (tightening direction T1) as shown in FIG. 2 relative to the container body 2, the ascending female thread portion 42a rotates relative to the ascending male thread portion 25a, and the inner plate 4 moves upward. Note that when the lid body 5 is rotated counterclockwise in plan view (loosening direction T2) relative to the container body 2, as will be described in detail later, the rotation of the inner plate 4 in the loosening direction T2 is restricted, so the ascending female thread portion 42a does not rotate relative to the ascending male thread portion 25a, and the vertical movement of the inner plate 4 is restricted.
[0039] The lid 5 is cylindrical with a top and includes a lid body 51 and a separate inner plug 52. The lid body 51 and the inner plug 52 are formed from different materials. For example, the lid 5 can be made of polypropylene (PP), and the inner plug 52 can be made of low-density polyethylene (LDPE). The lid body 5 is not limited to the lid body main body 51 and the inside plug 52 being separate parts, but may be integrally molded (one part).
[0040] The lid body 51 includes a disk-shaped top wall 51a extending horizontally, and an outer peripheral wall 51b extending downward from the outer edge of the top wall 51a, surrounding the mouth 20 of the container body 2. An internal thread 5a is provided on the inner peripheral surface of the outer peripheral wall 51b, which is threadedly engaged with the external thread 20a of the mouth 20. The internal thread 5a is a right-handed thread. By rotating the lid body 5 relative to the container body 2 in the loosening direction T2 as shown in FIG. 2, the internal thread 5a rotates relative to the external thread 20a in the loosening direction T2, and the lid body 5 is removed. Furthermore, by rotating the lid body 5 relative to the container body 2 in the tightening direction T1, the container body 2 is closed by the lid body 5.
[0041] The inner plug 52 has a cylindrical shape and protrudes downward from the underside of the top wall 51a. When the lid 5 is closed, the outer peripheral surface 52a of the inner plug 52 is in liquid-tight contact with the upper end of the inner peripheral surface 30a of the inner cylinder 3 via a packing 53 (described later). In other words, the inner plug 52 holds the upper end of the inner cylinder 3 between itself and the opening 20, generating frictional resistance against the inner cylinder 3.
[0042] A packing 53 (friction resistance member) is provided on the underside of the top wall 51a. The packing 53 is formed in a disk shape from an elastic material. When the lid 5 is rotated to the end in the fastening direction T1 relative to the mouth 20 of the container body 2, the packing 53 is sandwiched between the upper end surface of the peripheral wall 30 of the inner cylinder 3 and the underside of the top wall 51a, thereby closing the storage space S for the contents.
[0043] Next, how to use the container with lid 1 will be described.
[0044] To remove contents from the lidded container 1 configured as described above, as shown in FIGS. 1, 3, and 5, the lid 5 is rotated relative to the container body 2 in the loosening direction T2 shown in FIG. 2. That is, while holding the container body 2 with one hand and grasping the lid 5 with the other, the lid 5 is rotated in the loosening direction T2. When the lid 5 rotates in the loosening direction T2, the rotation of the inner tube 3 is restricted relative to the container body 2. That is, the anti-rotation protrusion 27 of the container body 2 engages with the engaging portion 33a of the elastic beam 33 of the inner tube 3, restricting the rotation of the inner tube 3. Therefore, the inner tube 3 does not rotate, and only the lid 5 rotates in the loosening direction T2. Then, when the male thread portion 20a of the opening 20 and the female thread portion 5a of the lid 5 are disengaged, the lid 5 can be removed from the container body 2, and the contents stored in the storage space S can be removed by hand, a spatula, or the like.
[0045] Here, when the lid 5 is fastened to the container body 2, the inner stopper 52 is fitted to the inner surface of the peripheral wall 30 of the center cylinder 3, and the packing 53 is sandwiched between the upper end surface of the peripheral wall 30 of the center cylinder 3 and the lower surface of the top wall 51a of the lid 5 in a state where frictional resistance is generated. Therefore, when the lid 5 is rotated in the fastening direction T1, a rotational force in the fastening direction T1 is transmitted from the inner stopper 52 and the packing 53 to the peripheral wall 30 of the center cylinder 3.
[0046] On the other hand, when the lid body 5 is rotated relative to the container body 2 in the tightening direction T1 shown in FIG. 2 , the center cylinder 3 is held in place by the frictional resistance between the center plug 52 and the packing 53, as described above, and the center cylinder 3 also rotates in the tightening direction T1 along with the lid body 5. The center cylinder 3 and the center plate 4 are fitted together in an elliptical shape when viewed in cross section. That is, the center plate 4, which is fitted to the center cylinder 3 in a non-rotational manner due to its shape, also rotates in the tightening direction T1. As described above, the ascending male thread portion 25a of the male screw shaft 25 and the ascending female thread portion 42a of the threaded cylindrical portion 42 are configured so that the threaded cylindrical portion 42 rises relative to the male screw shaft 25 when rotated in the tightening direction T1. Therefore, as the threaded cylindrical portion 42 rises, the center plate 4 slides upward relative to the center cylinder 3. The amount of rotation of the lid body 5 relative to the container body 2 and the amount of lift of the inner plate 4 relative to the inner cylinder 3 can be changed as appropriate, for example, by adjusting the pitch of the lifting male screw portion 25a and the lifting female screw portion 42a. Furthermore, by reversing the setting of the lifting mechanism and ratchet mechanism of the inner tray 4, for example from a left-handed screw to a right-handed screw, it is possible to configure the inner tray 4 to rise when the lid body 5 is loosened, and not to rise when the lid body 5 is tightened.
[0047] 5, when the lid body 5 is rotated in the fastening direction T1 relative to the container body 2 in this way, the inner plate 4 gradually rises relative to the inner cylinder 3. That is, the inner plate 4 rises every time the lid body 5 is attached to the container body 2 after the contents stored in the storage space S are removed, so even if the contents become low, there is no need to insert a finger or spatula deeply into the inner cylinder 3, and the contents can be easily removed.
[0048] As described above, in the lidded container 1 according to this embodiment, when the lid 5 is rotated in the loosening direction T2 relative to the container body 2, rotation of the inner cylinder 3 in the loosening direction T2 is restricted. When the lid 5 is rotated in the tightening direction T1, the inner stopper 52 of the lid 5 engages with the inner surface of the inner cylinder 3, and the inner cylinder 3 rotates together with the inner stopper 52 of the lid 5 due to frictional resistance. Because the inner cylinder 3 and the inner plate 4, which are non-circular in cross section, are in contact with each other along their entire circumferences, when the lid 5 is rotated in the tightening direction T1 to rotate the inner plate 4 together with the inner cylinder 3, the inner plate 4 rises relative to the container body 2. That is, the contents stored in the storage space S defined between the inner cylinder 3 and the inner plate 4 rise each time the lid 5 is attached to the container body 2, and the contents are always held above the container. This allows the contents to be easily removed even when they are low, improving usability.
[0049] When the inner cylinder 3 rotates in the loosening direction T2 relative to the container body 2, the ratchet portion restricts the rotation of the inner cylinder 3, and the inner plate 4 does not rotate either, so the inner plate 4 does not rise. On the other hand, when the inner cylinder 3 rotates in the tightening direction T1 relative to the container body 2, the ratchet portion causes the inner cylinder 3 to spin freely, allowing the inner cylinder 3 to rotate in the loosening direction T2. In this way, by providing the ratchet portion to the inner cylinder 3 and inner plate 4, rotation in the loosening direction T2, which is one of the rotation directions of the lid body 5, can be easily restricted.
[0050] Furthermore, since rotation of the inner cylinder 3 in the loosening direction T2 is restricted, the inner plate 4 can be prevented from descending in the opposite direction so as to move away from the upper end of the container body 2. Furthermore, since the contents are held at the top of the container, the surface area of the contents that comes into contact with the outside air can be kept small, which prevents the contents from deteriorating due to the increased surface area that comes into contact with the outside air later in use.
[0051] The inner plug 52 is separate from the lid body 51 of the lid body 5, and the lid body 51 and the inner plug 52 are formed from different materials. By using only the inner plug 52 as a separate part from the lid body 51 and made of a material that can provide frictional resistance, for example, the fit between the inner plug 52 and the inner surface of the center cylinder 3 can be improved, and the center cylinder 3 can be reliably rotated together with the rotation of the lid body 5.
[0052] Separate packing 53 is provided between inner plug 52 and inner cylinder 3. Therefore, separate packing 53 that can generate frictional resistance is interposed between inner plug 52 and inner cylinder 3, so that inner plug 52 can be fitted well with the inner surface of inner cylinder 3, and inner cylinder 3 can be reliably rotated together with rotation of lid body 5.
[0053] A window 28 is provided on the side of the container body 2, and the inner tube 3 is made of a translucent material, so that the position of the inner tray 4, the remaining amount of contents, etc. can be visually confirmed through the window 28 through the transparent inner tube 3.
[0054] 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.
[0055] For example, the inner plug 52 is separate from the lid body 51 of the lid body 5 and is made of a different material, but the lid body 51 and the inner plug 52 may be configured to be integral with each other.
[0056] Furthermore, the position, shape, and other configurations of the ratchet portion (the anti-rotation protrusion 27 of the container body 2 and the elastic beam 33 of the inner cylinder 3) are not limited to this embodiment and can be changed as appropriate.
[0057] In addition, in this embodiment, the window 28 is provided on the side of the container body 2, and the inner cylinder 3 is made of a light-transmitting material, but the present invention is not limited to this configuration. For example, the window 28 may be omitted, and the shape, number, and other configurations of the window 28 may be set as appropriate.
[0058] 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.
