Summary of the Invention
Problems to be Solved by the Invention
[0004] When a new cartridge is installed in the operating section, and the cap and operating section are gripped to detach the cap from the sleeve, the clamping force of the cap against the outer surface of the sleeve increases by the amount of gripping, restricting the relative rotation of the cap and sleeve in the circumferential direction. As a result, the cap may rotate circumferentially with the sleeve relative to the operating section, potentially causing the rod-shaped contents to rise and strike the top wall of the cap. Furthermore, by leaving the cap attached to the sleeve while installing a new cartridge into the control unit, it is possible to prevent the mistake of installing the new cartridge upside down into the control unit.
[0005] The present invention provides a cartridge for a dispensing container that prevents relative rotation of the sleeve and the operating part in the circumferential direction, even when the cartridge cap and the operating part are gripped in order to detach the cartridge cap from the sleeve while a new cartridge is attached to the operating part. [Means for solving the problem]
[0006] A cartridge for a dispensing container according to one aspect of the present invention comprises a transmission shaft extending vertically along the axial direction of the container, a sleeve arranged to surround the outside of the transmission shaft and rotatable circumferentially with respect to the transmission shaft, a tray inserted inside the sleeve and movable vertically with respect to the sleeve while its rotation in the circumferential direction is restricted, and which holds a rod-shaped contents, and a cartridge cap detachably attached to the sleeve, wherein as the sleeve rotates with respect to the transmission shaft, the tray rotates together with the sleeve and moves up and down with respect to the sleeve, and the cartridge for a dispensing container is attached to and detached from the operating part through the upper end opening of a bottomed cylindrical operating part, wherein the upper part of the cartridge cap is detachably fitted into the upper part, and the lower inner circumferential surface is radially separated outward from the outer circumferential surface of the sleeve.
[0007] In the cartridge cap (hereinafter referred to as "cap"), the sleeve is detachably fitted inside the upper part, and the inner circumferential surface of the lower part is radially separated from the outer circumferential surface of the sleeve. Therefore, when removing the cap from the sleeve with a new cartridge installed in the operating part, gripping the lower part of the cap prevents an increase in the tightening force of the cap against the outer circumferential surface of the sleeve, keeping the cap and sleeve in a state where they can rotate relative to each other in the circumferential direction, thereby suppressing relative rotation of the sleeve and the operating part in the circumferential direction.
[0008] When attached to the operating unit, the lower end of the cartridge cap surrounds the outside of the upper end of the operating unit, and the inner circumferential surface of the lower end of the cartridge cap and the outer circumferential surface of the upper end of the operating unit may each be non-circular when viewed from above and below, and may be formed to be able to engage with each other in the circumferential direction.
[0009] With the cartridge mounted on the operating section, the lower end of the cap surrounds the outside of the upper end of the operating section. The inner circumferential surface of the lower end of the cap and the outer circumferential surface of the upper end of the operating section are both non-circular when viewed from above and below, and are formed to engage with each other in the circumferential direction. This restricts the relative rotation of the cap and the operating section in the circumferential direction. As a result, even when gripping the cap and the operating section to remove the cap from the sleeve with a new cartridge mounted on the operating section, the sleeve and the operating section are prevented from rotating relative to each other in the circumferential direction. [Effects of the Invention]
[0010] According to the present invention, even when a new cartridge is attached to the operating section, and the cartridge cap and the operating section are grasped in order to detach the cartridge cap from the sleeve, it is possible to suppress relative rotation of the sleeve and the operating section in the circumferential direction. [Brief explanation of the drawing]
[0011] [Figure 1] This is a cross-sectional view of a dispensing container according to one embodiment. [Figure 2] Figure 1 is an explanatory diagram of the operation of the dispensing container when in use. [Figure 3] This is a cross-sectional view of the cartridge according to the first embodiment. [Figure 4] This is a cross-sectional view of the cartridge according to the second embodiment. [Figure 5] Figure 4 is a bottom view of the cartridge cap. [Modes for carrying out the invention]
[0012] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The dispensing container 1 shown in Figures 1 and 2 is used by dispensing a rod-shaped contents (not shown). Examples of rod-shaped contents include cosmetics (lipstick, lip balm, stick eyeshadow, etc.), pharmaceuticals, and adhesives. Unless otherwise specified, each component of the dispensing container 1 is an injection-molded product made of resin material such as olefin resin.
[0013] The dispensing container 1 comprises a bottomed cylindrical operating section 10, a transmission shaft 23, a sleeve 11, and a middle tray 12. The operating section 10, transmission shaft 23, sleeve 11, and middle tray 12 are arranged such that their respective central axes lie on a common axis.
[0014] Hereinafter, the common axis will be referred to as the container axis O, and the direction along the container axis O will be referred to as the vertical direction. In a plan view from the vertical direction, the direction intersecting the container axis O will be referred to as the radial direction, and the direction revolving around the container axis O will be referred to as the circumferential direction. In the dispensing container 1, the side of the operating section 10 along the vertical direction that is on the bottom wall (bottom wall 21a of the outer cylinder 21) will be referred to as the downward direction, and the opposite side will be referred to as the upward direction. Of the circumferential directions, the direction that raises the inner tray 12 will be referred to as the dispensing direction, and the direction that lowers the inner tray 12 will be referred to as the storage direction.
[0015] The operating section 10 is formed in a bottomed cylindrical shape and constitutes the lower outer casing of the dispensing container 1. The operating section 10 comprises an outer casing 21 and an inner component 22.
[0016] The outer cylinder 21 is formed in a bottomed cylindrical shape. A fitting portion 21b extending upward is formed on the bottom wall 21a (the bottom wall of the operation portion) of the outer cylinder 21. The fitting portion 21b is formed in a cylindrical shape and is disposed coaxially with the container axis O. The inner member 22 is formed in a cylindrical shape and is fitted inside the outer cylinder 21. The inner member 22 is provided so as not to be rotatable in the circumferential direction with respect to the outer cylinder 21 in a state where the upper portion protrudes upward from the outer cylinder 21. The inner member 22 may be integrally formed with the outer cylinder 21. If the shape of the inner circumferential surface of the inner member 22 is circular in plan view, the shape of the outer circumferential surface of the inner member 22 may be a shape other than circular in plan view.
[0017] The transmission shaft 23 is provided inside the outer cylinder 21 and supports the middle plate 12 so as to be movable up and down. The lower end portion of the transmission shaft 23 is detachably fixed to the bottom wall 21a of the outer cylinder 21. The transmission shaft 23 includes a fixed shaft member 23a and an outer transmission shaft 23b.
[0018] The fixed shaft member 23a is provided so as not to be rotatable in the circumferential direction with respect to the outer cylinder 21. The fixed shaft member 23a is formed in a cylindrical shape and is disposed coaxially with the container axis O. An inner spiral groove 26a is formed on the outer circumferential surface of the fixed shaft member 23a. The inner spiral groove 26a extends spirally upward as it goes in the pay-out direction. The inner spiral groove 26a is formed in two. However, the inner spiral groove 26a may be one or three or more.
[0019] A flange-shaped pedestal portion 25 that protrudes radially outward and extends continuously over the entire circumference is formed at the lower end portion of the fixed shaft member 23a. The pedestal portion 25 is disposed coaxially with the container axis O. On the lower surface of the pedestal portion 25, a lower cylindrical portion 27 extending downward is formed. The lower cylindrical portion 27 is arranged coaxially with the container axis O. The lower cylindrical portion 27 is inserted into the fitting portion 21b of the operation portion 10. On the outer peripheral surface of the lower cylindrical portion 27 and the inner peripheral surface of the fitting portion 21b, concavo-convex portions engaging with each other in the circumferential direction are provided along the circumferential direction. By the concavo-convex portions of the lower cylindrical portion 27 and the fitting portion 21b engaging with each other in the circumferential direction, the relative rotation of the fixed shaft member 23a with respect to the operation portion 10 is restricted. On the outer peripheral edge portion of the pedestal portion 25, a fitting portion 24 extending downward is formed. The fitting portion 24 is arranged coaxially with the container axis O. Inside the fitting portion 24, the fitting portion 21b is detachably undercut-fitted. Thereby, the vertical movement of the fixed shaft member 23a with respect to the operation portion 10 is restricted. At the lower end portion of the fitting portion 24, an overhanging portion 24a protruding outward in the radial direction is formed. On the outer peripheral surface of the upper portion of the fitting portion 24, a circumferential groove 24b continuously extending over the entire circumference is formed.
[0020] The outer transmission shaft 23b is formed in a cylindrical shape and is arranged coaxially with the container axis O. Inside the outer transmission shaft 23b, a portion of the fixed shaft member 23a that is located above the pedestal portion 25 and provided with an inner spiral groove 26a is inserted. At the lower end portion of the outer transmission shaft 23b, a first engaging protrusion 31 protruding inward in the radial direction is formed. The first engaging protrusion 31 is accommodated in the inner spiral groove 26a of the fixed shaft member 23a. As the outer transmission shaft 23b rotates circumferentially with respect to the fixed shaft member 23a, the first engaging protrusion 31 moves spirally in the inner spiral groove 26a, and thereby the outer transmission shaft 23b moves up and down with respect to the fixed shaft member 23a. Two first engaging protrusions 31 are provided at intervals in the circumferential direction according to the number of the inner spiral grooves 26a. Each first engaging protrusion 31 extends along the inner spiral groove 26a. On the outer peripheral surface of the outer transmission shaft 23b, an outer spiral groove 32 is formed. The outer spiral groove 32 extends upward as it goes in the feeding direction. Two outer spiral grooves 32 are formed. However, the outer spiral groove 32 may be one or three or more.
[0021] The sleeve 11 is positioned to surround the outside of the transmission shaft 23 and is rotatably mounted circumferentially with respect to the transmission shaft 23 and the operating part 10. The lower part of the sleeve 11 is inserted into the inside of the operating part 10. The upper part of the sleeve 11 protrudes upward from the operating part 10. The lower end of the sleeve 11 is inserted into the radial gap between the inner circumferential surface of the operating part 10 and the outer circumferential edge of the base part 25. The lower end opening edge of the sleeve 11 is supported by the upper surface of the overhang 24a. The upper end opening surface of the sleeve 11 is inclined with respect to a horizontal plane perpendicular to the vertical direction. A downward projection 42 is formed at the lower end of the sleeve 11, projecting radially inward. The downward projection 42 engages with the upper and lower edges of the circumferential groove 24b of the transmission shaft 23 while being housed within the groove 24b. As a result, the sleeve 11 is supported on the transmission shaft 23 so as to be rotatable in the circumferential direction, while its vertical movement relative to the operating part 10 is restricted. Multiple downward projections 42 are formed at intervals in the circumferential direction (for example, four). Alternatively, the downward projections 42 may be formed continuously around the entire circumference of the sleeve 11. An upper projection 43 is formed on the lower part of the sleeve 11, projecting radially inward. The upper projection 43 is located above the lower projection 42. Multiple upper projections 43 are formed at intervals in the circumferential direction (for example, two).
[0022] The inner tray 12 is inserted inside the sleeve 11 and is provided to be movable in the vertical direction while its rotation in the circumferential direction is restricted relative to the sleeve 11, and it holds the rod-shaped contents. The inner tray 12 comprises an outer movable cylinder 51 and an inner tray body 52.
[0023] The inner tray body 52 comprises a contents holding section 55 and an inner movable cylinder 56. The contents holding section 55 and the inner movable cylinder 56 are integrally formed.
[0024] The contents holding section 55 is formed in a bottomed cylindrical shape and is arranged coaxially with the container axis O. The contents holding section 55 is housed inside the sleeve 11 in a portion located above the transmission axis 23. A rod-shaped contents are held inside the contents holding section 55. The rod-shaped contents are held in a state where they protrude upward from the contents holding section 55.
[0025] The inner movable cylinder 56 extends downward from the bottom wall of the contents holding section 55 and is arranged coaxially with the container axis O. The inner movable cylinder 56 surrounds the outside of the outer transmission shaft 23b. The inner movable cylinder 56 has a projection 56a that protrudes radially outward and extends vertically. The lower end of the inner movable cylinder 56 has an inner stopper projection 56b that protrudes radially outward. The circumferential positions of the inner stopper projection 56b and the projection 56a are different from each other. A second engaging projection 56c is formed at the lower end of the inner movable cylinder 56, projecting radially inward. The second engaging projection 56c is housed within the outer helical groove 32. As the inner movable cylinder 56 rotates circumferentially with respect to the outer transmission shaft 23b, the second engaging projection 56c moves spirally within the outer helical groove 32, causing it to move up and down relative to the outer transmission shaft 23b. Two second engaging projections 56c are provided, spaced apart circumferentially to match the number of grooves in the outer helical groove 32. Each second engaging projection 56c extends along the outer helical groove 32.
[0026] The outer movable cylinder 51 is provided so as to be able to move up and down relative to the sleeve 11, with its rotation in the circumferential direction restricted. The outer movable cylinder 51 is arranged coaxially with the container axis O. The outer movable cylinder 51 is inserted between the outer circumferential surface of the inner movable cylinder 56 and the inner circumferential surface of the sleeve 11. The lower end opening edge of the outer movable cylinder 51 is in contact with or close to the upper surface of the base portion 25. A first restricting groove 51a extending in the vertical direction is formed on the outer circumferential surface of the outer movable cylinder 51. The upper projection 43 of the sleeve 11 is housed in the first restricting groove 51a so as to be movable in the vertical direction, while its movement in the circumferential direction is restricted. The upper end of the first restricting groove 51a is open upward, and the lower end of the first restricting groove 51a is closed. The upward movement of the outer movable cylinder 51 relative to the sleeve 11 is restricted by the upper projection 43 contacting the lower end surface of the first restricting groove 51a. An outer stopper projection 51b is formed at the upper end of the outer movable cylinder 51, projecting radially inward. The outer stopper projection 51b faces the inner stopper projection 56b of the inner movable cylinder 56 in the vertical direction. The inner stopper projection 56b contacts the lower end surface of the outer stopper projection 51b, thereby restricting the upward movement of the inner tray body 52 relative to the outer movable cylinder 51. A second restricting groove 51c extending in the vertical direction is formed on the inner circumferential surface of the outer movable cylinder 51. The circumferential positions of the outer stopper projection 51b and the second restricting groove 51c are different from each other. Both ends of the second restricting groove 51c in the vertical direction are open in the vertical direction. The projection 56a of the inner movable cylinder 56 is housed within the second restricting groove 51c so as to be movable in the vertical direction while its circumferential movement is restricted. As a result, the inner tray body 52 is provided so as to be movable in the vertical direction relative to the outer movable cylinder 51 while its circumferential movement is restricted.
[0027] Next, the operation of the dispensing container 1 described above will be explained. When using the dispensing container 1, first grasp the sleeve 11 and the operating part 10, respectively, and rotate the sleeve 11 and the operating part 10 relative to each other in the dispensing direction. At this time, since the inner part 22 and the fixed shaft member 23a are attached to the outer cylinder 21 so as not to rotate relative to each other, the outer cylinder 21, the inner part 22, and the fixed shaft member 23a rotate together as a single unit. On the other hand, since the sleeve 11 and the outer movable cylinder 51, and the outer movable cylinder 51 and the inner tray body 52 are each provided so as not to rotate relative to each other, the sleeve 11 and the inner tray 12 rotate together as a single unit.
[0028] When the operating section 10 and the sleeve 11 are rotated relative to each other, at least one of the following occurs: the fixed shaft member 23a and the outer transmission shaft 23b rotate together with respect to the inner movable cylinder 56, or the fixed shaft member 23a rotates with respect to the outer transmission shaft 23b.
[0029] When the fixed shaft member 23a and the outer transmission shaft 23b rotate together relative to the inner movable cylinder 56, the second engaging projection 56c moves spirally within the outer helical groove 32, causing the inner movable cylinder 56 (middle pan body 52) to rise relative to the transmission shaft 23. This operation, in which the middle pan body 52 rises due to the relative rotation of the transmission shaft 23 and the inner movable cylinder 56 in the payout direction, is referred to as the "first operation" in this specification.
[0030] When the fixed shaft member 23a rotates relative to the outer transmission shaft 23b, the first engaging projection 31 moves spirally within the inner helical groove 26a, causing the outer transmission shaft 23b to rise relative to the fixed shaft member 23a. At this time, the second engaging projection 56c is pushed up via the inner surface of the outer helical groove 32, causing the inner pan body 52 to rise together with the outer transmission shaft 23b. In this specification, the operation in which the inner pan body 52 rises together with the outer transmission shaft 23b due to the relative rotation of the fixed shaft member 23a and the outer transmission shaft 23b in the payout direction is referred to as the "second operation".
[0031] In other words, when the operating unit 10 and the sleeve 11 are rotated relative to each other in the dispensing direction, the inner tray body 52 rises due to at least one of the first and second actions. This causes the rod-shaped contents to be dispensed upward from the sleeve 11. Which of the first and second actions occurs is determined by the frictional resistance between each component, etc. Note that both the first and second actions may occur simultaneously.
[0032] In the initial stage when the inner tray body 52 rises due to the first or second operation, the inner tray body 52 rises relative to the outer movable cylinder 51 (first rising process). In the first upward movement, the projection 56a of the inner movable cylinder 56 is guided by the second restricting groove 51c of the outer movable cylinder 51, thereby restricting the relative rotation of the outer movable cylinder 51 and the inner tray body 52. The inner stopper projection 56b then contacts the lower end surface of the outer stopper projection 51b as the inner tray body 52 rises relative to the outer movable cylinder 51.
[0033] After the first upward movement, if the inner tray body 52 attempts to rise further due to the first or second movement, the outer movable cylinder 51 is pushed upward via the inner stopper projection 56b and the outer stopper projection 51b. As a result, the inner tray body 52 rises relative to the sleeve 11 together with the outer movable cylinder 51 (second upward movement). During the second upward movement, the upper projection 43 of the sleeve 11 is housed within the first regulating groove 51a, so the relative rotation of the sleeve 11 and the outer movable cylinder 51 is restricted. The outer movable cylinder 51 rises relative to the sleeve 11 until the lower end surface of the first regulating groove 51a contacts the upper projection 43. In this embodiment, a configuration in which the second rising process occurs after the first rising process has been described, but the first rising process may occur after the second rising process, or the first and second rising processes may occur simultaneously.
[0034] When lowering the inner tray 12, the operating section 10 and the sleeve 11 are rotated relative to each other in the housing direction. As a result, the inner tray body 52 descends relative to the sleeve 11, either by the fixed shaft member 23a and the outer transmission shaft 23b rotating together relative to the inner movable cylinder 56, or by the fixed shaft member 23a rotating relative to the outer transmission shaft 23b. As the inner tray body 52 descends, the outer movable cylinder 51 descends together with the inner tray body 52 due to its own weight, etc. Then, the lower end opening edge of the outer movable cylinder 51 comes into contact with the upper surface of the base portion 25, restricting the descent of the outer movable cylinder 51 relative to the sleeve 11. Subsequently, as the inner tray body 52 descends further, the inner tray body 52 descends relative to the sleeve 11 and the outer movable cylinder 51.
[0035] In the dispensing container 1 described above, as shown in Figure 3, a cartridge 101 for the dispensing container, which is composed of a sleeve 11, a tray 12, and a transmission shaft 23, is detachably attached to the operating section 10, which is composed of an outer cylinder 21 and an inner component 22. To assemble the cartridge 101 to the operating unit 10, the cartridge 101 is inserted into the operating unit 10 through the upper end opening of the central part 22 of the operating unit 10, and the fitting part 21b is fitted into the fitting part 24 by undercutting, thereby mounting the cartridge 101 to the operating unit 10. When the rod-shaped contents have been used up, etc., to remove the cartridge 101 from the operating unit 10, pulling the cartridge 101 up relative to the operating unit 10 releases the engagement between the fitting portion 24 and the fitting portion 21b, and the cartridge 101 is removed from inside the operating unit 10 through the upper end opening of the internal fitting 22 of the operating unit 10.
[0036] In this embodiment, the cartridge 101 further includes a cartridge cap 44 (hereinafter referred to as cap 44) that is detachably attached to the sleeve 11. The cap 44 is formed in a top-cylindrical shape. The lower surface of the top wall of the cap 44 is located above the rod-shaped contents. The sleeve 11 is detachably fitted into the upper part of the cap 44, and the inner circumferential surface of the lower part is radially separated from the outer circumferential surface of the sleeve 11. The inner circumferential surface of the upper part of the cap 44 is in relative rotational contact with the outer circumferential surface of the sleeve 11 around its entire circumference. The diameter of the upper part of the cap 44 is smaller than the diameter of the lower part of the cap 44. The connection portion between the upper and lower parts of the cap 44 is a stepped portion with the front and back surfaces facing in the vertical direction. The vertical size of the lower part of the cap 44 is larger than the vertical size of the upper part of the cap 44. The cap 44 is located above the operating section 10 when the cartridge 101 is mounted on the operating section 10.
[0037] As described above, with the cartridge 101 according to this embodiment, the sleeve 11 is detachably fitted into the upper part of the cap 44, and the lower inner circumferential surface is radially separated from the outer circumferential surface of the sleeve 11. Therefore, when removing the cap 44 from the sleeve 11 with a new cartridge 101 attached to the operating unit 10, gripping the lower part of the cap 44 prevents an increase in the tightening force of the cap 44 against the outer circumferential surface of the sleeve 11, making it possible to maintain the cap 44 and sleeve 11 in a state where they can rotate relative to each other in the circumferential direction, thereby suppressing the relative rotation of the sleeve 11 and the operating unit 10 in the circumferential direction.
[0038] Next, a cartridge 102 according to a second embodiment of the present invention will be described with reference to Figures 4 and 5. In this second embodiment, the same reference numerals are used for parts that are the same as those in the first embodiment, and their descriptions are omitted. Only the differences will be described.
[0039] In the cartridge 102 of this embodiment, when attached to the operating section 20, the lower end of the cap 45 surrounds the outside of the upper end of the operating section 20, and the inner circumferential surface of the lower end of the cap 45 and the outer circumferential surface of the upper end of the operating section 20 are each non-circular when viewed from above and below, and are formed to be able to engage with each other in the circumferential direction. The upper part of the cap 45 is formed in a cylindrical shape, and the lower part is formed in a square tube shape. Of the internal component 46 of the operating section 20, the upper part that protrudes upward from the outer cylinder 21 is formed in a rectangular tubular shape and is inserted into the lower end of the cap 45. The outer circumferential surface of the upper part of the internal component 46 and the inner circumferential surface of the lower end of the cap 45 extend parallel to each other when viewed from the vertical direction.
[0040] As described above, with the cartridge 102 according to this embodiment, when the cartridge 102 is mounted on the operating unit 20, the lower end of the cap 45 surrounds the outer surface of the upper part of the inner component 46, and the inner circumferential surface of the lower end of the cap 45 and the outer circumferential surface of the upper part of the inner component 46 are each non-circular when viewed from above and below, and are formed to be able to engage with each other in the circumferential direction, so that the relative rotation of the cap 45 and the operating unit 20 in the circumferential direction is restricted. As a result, even when gripping the cap 45 and the operating unit 20 in order to remove the cap 45 from the sleeve 11 with a new cartridge 102 mounted on the operating unit 20, the relative rotation of the sleeve 11 and the operating unit 20 in the circumferential direction can be restricted.
[0041] While preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications are possible without departing from the spirit of the invention. The present invention is not limited by the above description, but only by the appended claims.
[0042] In the embodiments described above, a configuration was described in which the transmission shaft 23 comprises a fixed shaft member 23a and an outer transmission shaft 23b, but the configuration is not limited to this. The transmission shaft 23 only needs to have at least a fixed shaft member 23a. In the embodiments described above, the operating sections 10 and 20 were configured to include an outer cylinder 21 and an inner component 22, but the configuration is not limited to this. The operating sections 10 and 20 may consist only of the outer cylinder 21. In the embodiments described above, the inner tray body 52 was described as being formed in a bottomed cylindrical shape, but the inner tray body 52 may also be configured without a bottom wall as long as it is capable of accommodating the lower end of the rod-shaped contents. In the second embodiment described above, the lower part of the cap 45 and the upper part of the inner component 46 were each formed in a square cylindrical shape. However, the lower part of the cap 45 and the upper part of the inner component 46 may also be formed in a triangular cylindrical shape or a polygonal cylindrical shape with five or more sides. Furthermore, the inner circumferential surface of the lower part of the cap 45 and the outer circumferential surface of the upper part of the inner component 46 may each have protrusions and recesses that engage with each other in the circumferential direction.
[0043] Furthermore, without departing from the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and modifications may be combined as appropriate. [Explanation of Symbols]
