Description

[Technical field]

[0001] The present invention relates to a dispensing container. [Background technology]

[0002] A known dispensing container has a sleeve and an inner plate provided inside the sleeve for holding a rod-shaped content, and the inner plate is slid vertically relative to the sleeve to move the rod-shaped content up and down (see, for example, Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 61-174520 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the lower end of the rod-shaped content, which is surrounded from the radially outer side by the sleeve or inner plate, cannot be applied to the application area, and there was room for improvement in reducing the remaining amount of rod-shaped content.

[0005] The present invention provides a dispensing container that can reduce the amount of remaining rod-shaped content. [Means for solving the problem]

[0006] A dispensing container according to one aspect of the present invention comprises a cylindrical operating part with a bottom, a transmission shaft having a spiral groove extending around a container axis and extending upward from a bottom wall of the operating part, a sleeve inserted between an inner circumferential surface of the operating part and an outer circumferential surface of the transmission shaft and rotatable in a circumferential direction around the container axis relative to the operating part and the transmission shaft, and an inner plate provided inside the sleeve for holding a rod-shaped content, wherein the sleeve is provided with an engagement protrusion that engages with the spiral groove, and when the sleeve is rotated in the dispensing direction relative to the transmission shaft, the engagement protrusion spirals within the spiral groove. When the sleeve moves toward the operating unit, the transmission shaft and the middle plate, the sleeve moves downward relative to the operating unit, the transmission shaft and the middle plate, and the sleeve and the middle plate are each provided with a first engagement portion and a second engagement portion which engage with each other when the sleeve is lowered to regulate the relative circumferential movement of the sleeve and the middle plate, and the middle plate and the transmission shaft are each provided with a third engagement portion and a fourth engagement portion which engage with each other when the lowered sleeve is rotated together with the middle plate in the circumferential direction relative to the transmission shaft to raise the middle plate relative to the transmission shaft.

[0007] When the sleeve is rotated circumferentially toward the payout side relative to the operating part and the transmission shaft, the engagement protrusion of the sleeve moves spirally within the spiral groove of the transmission shaft, causing the sleeve to move downward relative to the operating part, the transmission shaft and the center plate, and causing the rod-shaped content to protrude from the upper end opening of the sleeve. The sleeve and the middle plate are each provided with a first engaging portion and a second engaging portion that engage with each other when the sleeve is lowered to restrict the relative movement of the sleeve and the middle plate in the circumferential direction, and the middle plate and the transmission shaft are each provided with a third engaging portion and a fourth engaging portion that engage with each other when the lowered sleeve is rotated together with the middle plate in the circumferential direction relative to the transmission shaft to the payout side. Therefore, it becomes possible to use the rod-shaped contents by exposing the lower end portion upward from the upper end opening of the sleeve, and the remaining amount of the rod-shaped contents can be reduced.

[0008] The middle plate is arranged on the upper end surface of the transmission shaft, the outer peripheral edge portion of the middle plate extends radially outward from the upper end surface of the transmission shaft, and the upper end surface of the transmission shaft may be provided with a piercing protrusion that penetrates the middle plate in the vertical direction and pierces the rod-shaped content.

[0009] A piercing projection is provided on the upper end surface of the transmission shaft, which penetrates the inner plate in the vertical direction and pierces the rod-shaped contents, making it difficult for the rod-shaped contents to break. When the lowered sleeve is rotated in the payout direction along the circumferential direction relative to the transmission shaft, the inner plate rises relative to the sleeve, making it easier to remove the piercing protrusion from the rod-shaped contents and reliably reducing the remaining amount of rod-shaped contents.

[0010] When the third engagement portion and the fourth engagement portion engage with each other, when the middle plate rises relative to the transmission shaft, the upper edge of the piercing protrusion may be positioned at the same vertical position or below the upper surface of the middle plate.

[0011] By engaging the third engagement portion and the fourth engagement portion with each other, when the inner plate is raised relative to the transmission shaft, the upper edge of the piercing protrusion is positioned at the same vertical position or below the upper surface of the inner plate, so that the piercing protrusion can be reliably removed from the rod-shaped contents when the inner plate is raised relative to the transmission shaft.

[0012] The sleeve may be provided with a sliding protrusion that is elastically displaceable in a radial direction and that abuts against an inner circumferential surface of the operating portion.

[0013] The sleeve is provided with a sliding protrusion that is elastically displaceable in the radial direction and abuts against the inner surface of the operating part.When the sleeve is rotated circumferentially toward the payout side relative to the transmission shaft, the sliding protrusion slides against the inner surface of the operating part, generating a frictional force. This makes it possible to prevent the sleeve from rotating unintentionally too much relative to the transmission shaft, and the amount of rod-shaped content paid out can be easily adjusted.

[0014] The sleeve may be provided with a cantilevered elastic plate having a rear end on the payout side along the circumferential direction that is a fixed end connected to the sleeve and a front end on the payout side along the circumferential direction that is a free end, and the sliding protrusion may be formed on the elastic plate.

[0015] Since the sliding protrusion is formed on a cantilevered elastic plate, when the sleeve is rotated in the payout direction along the circumferential direction relative to the transmission shaft, a circumferential compressive force is applied to the elastic plate, making it easier to flex and deform the elastic plate in the radial direction. Therefore, when a force is applied to rotate the sleeve in the payout direction along the circumferential direction relative to the transmission shaft, it is possible to reliably prevent the sleeve from rotating unintentionally by a large amount relative to the transmission shaft. Effect of the Invention

[0016] According to the present invention, the amount of remaining rod-shaped contents can be reduced. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is used by dispensing a stick-shaped content (not shown). Examples of the stick-shaped content include cosmetics (lipstick, lip balm, stick eye shadow, etc.), medicines, glue, etc.

[0019] Dispensing container 1 comprises a cylindrical operating unit 10 with a bottom, a transmission shaft 14, a sleeve 11, an inner plate 12, and a lid 13. Operating unit 10, transmission shaft 14, sleeve 11, and inner plate 12 are arranged with their respective central axes positioned on a common axis. Hereinafter, the common axis will be referred to as container axis O, and the direction along container axis O will be referred to as the vertical direction. A direction intersecting container axis O when viewed from the vertical direction will be referred to as the radial direction, and a direction going around container axis O when viewed from the vertical direction will be referred to as the circumferential direction. In dispensing container 1, the side of lid body 13 along the vertical direction will be referred to as the upper side, and the side of bottom wall 10a of operating unit 10 along the vertical direction will be referred to as the lower side.

[0020] The transmission shaft 14 has a spiral groove 14a extending in the circumferential direction and extends upward from the bottom wall 10a of the operating unit 10. The transmission shaft 14 is formed in a cylindrical shape extending in the vertical direction. The lower end of the transmission shaft 14 forms a base portion 14b that protrudes radially outward. The base portion 14b is fixed to the bottom wall 10a of the operating unit 10, and the relative movement of the transmission shaft 14 and the operating unit 10 is restricted. The outer peripheral surface of the portion of the transmission shaft 14 located above the base portion 14b is spaced radially inward from the inner peripheral surface of the operating unit 10. The upper portion of the transmission shaft 14 protrudes upward from the upper end opening of the operating unit 10.

[0021] The sleeve 11 is inserted between the inner peripheral surface of the operating unit 10 and the outer peripheral surface of the transmission shaft 14, and is provided so as to be rotatable in the circumferential direction relative to the operating unit 10 and the transmission shaft 14. The lower end of the sleeve 11 is inserted into the upper end of the operating unit 10. The sleeve 11 is provided with an engagement protrusion 11a that engages with the spiral groove 14a of the transmission shaft 14. The engagement protrusion 11a is formed on the inner peripheral surface of the lower end of the sleeve 11. When the sleeve 11 is rotated toward the payout side X along the circumferential direction relative to the transmission shaft 14, the engagement protrusion 11a moves spirally within the spiral groove 14a, and the sleeve 11 moves downward relative to the operation unit 10, the transmission shaft 14, and the inner plate 12.

[0022] The sleeve 11 is provided with a sliding protrusion 11b and an elastic plate piece 11c. As shown in Fig. 4, the elastic plate piece 11c is a cantilevered plate spring in which the rear end of the payout side X along the circumferential direction is a fixed end connected to the sleeve 11, and the front end of the payout side X along the circumferential direction is a free end. The elastic plate piece 11c is disposed inside a through hole formed in a portion of the lower end of the sleeve 11 located above the engagement protrusion 11a. The front and back surfaces of the elastic plate piece 11c face in the radial direction. A plurality of elastic plate pieces 11c (two in the illustrated example) are provided at equal intervals in the circumferential direction. The sliding protrusion 11b is formed on the elastic plate piece 11c, and is elastically displaced in the radial direction as the elastic plate piece 11c elastically deforms in the radial direction. The sliding protrusion 11b is formed at the front end of the elastic plate piece 11c on the payout side X along the circumferential direction. The sliding protrusion 11b abuts against the inner peripheral surface of the operating part 10.

[0023] The sleeve 11 is configured by connecting an upper end tubular portion 11d and a main body tubular portion 11e in the up-down direction. The upper end tubular portion 11d constitutes the upper end of the sleeve 11, and the main body tubular portion 11e constitutes a portion of the sleeve 11 located below the upper end. The upper end tubular portion 11d and the main body tubular portion 11e may be formed integrally. The lower end opening edge of the upper end tubular portion 11d protrudes radially outward from the outer circumferential surface of the main body tubular portion 11e and faces the upper end opening edge of the operating portion 10 in the up-down direction.

[0024] The lid body 13 opens and closes the upper end opening of the sleeve 11. The lid body 13 is detachably fitted to the upper end tubular portion 11d of the sleeve 11. As a result, when the sleeve 11 is lowered from the upper end position before opening due to the shortening and shrinking of the rod-shaped contents, the upper end opening of the sleeve 11 can be closed with the lid body 13 without returning the sleeve 11 to its original upper end position. The cover 13 is connected to the upper end tubular portion 11d of the sleeve 11 via a hinge portion 13b. The cover 13, the upper end tubular portion 11d of the sleeve 11, and the hinge portion 13b form a hinge cap. Note that the hinge portion 13b does not necessarily have to be provided.

[0025] The inner plate 12 is provided inside the sleeve 11 and holds a rod-shaped content. The inner plate 12 is disposed on the upper end surface of the transmission shaft 14. The outer peripheral edge of the inner plate 12 protrudes radially outward from the upper end surface of the transmission shaft 14. The inner plate 12 is formed in an annular shape and disposed coaxially with the container axis O. The inner plate 12 is formed with an insertion shaft 12a that protrudes downward and is inserted into the upper end of the transmission shaft 14. The insertion shaft 12a is formed in a cylindrical shape with a bottom. The insertion shaft 12a extends downward from the opening peripheral edge on the lower surface of the inner plate 12.

[0026] The upper end surface of the transmission shaft 14 is provided with a piercing projection 14c that penetrates the middle plate 12 in the vertical direction and pierces the rod-shaped contents. The piercing projection 14c is inserted into a long hole 12b formed in the middle plate 12. As shown in FIG. 2, the long hole 12b extends in the circumferential direction, and the piercing projection 14c is inserted into the front end of the long hole 12b on the payout side X along the circumferential direction. A plurality of piercing projections 14c are provided at intervals in the circumferential direction. As shown in FIG. 3, the upper end surface of the transmission shaft 14 is provided with a rib 14d connected to the surface of the piercing projection 14c facing the rear side of the payout side X along the circumferential direction. The vertical size of the rib 14d decreases as it moves away from the piercing projection 14c in the circumferential direction. The upper end edge of the rib 14d at the connection portion with the piercing projection 14c is located at the same vertical position or below the upper surface of the middle plate 12.

[0027] 5, the sleeve 11 and the inner plate 12 are each provided with a first engagement portion 21 and a second engagement portion 22 that engage with each other when the sleeve 11 descends to restrict the relative movement of the sleeve 11 and the inner plate 12 in the circumferential direction. In the illustrated example, the first engagement portion 21 and the second engagement portion 22 engage with each other when the sleeve 11 is located at the lowering end position. Note that the first engagement portion 21 and the second engagement portion 22 may also engage with each other before the sleeve 11 reaches the lowering end position during the process of descending. The first engagement portion 21 is an uneven portion provided over the entire circumference on the inner peripheral surface of the upper end cylindrical portion 11d of the sleeve 11. The second engagement portion 22 is an uneven portion provided over the entire circumference on the outer peripheral surface of the center plate 12, which is located radially outward from the upper end surface of the transmission shaft 14. The first engagement portion 21 and the second engagement portion 22 mesh with each other in the circumferential direction over the entire circumference when the sleeve 11 is lowered.

[0028] The middle plate 12 and the transmission shaft 14 are each provided with a third engagement portion 23 and a fourth engagement portion 24 that engage with each other when the lowered sleeve 11 is rotated together with the middle plate 12 toward the payout side X along the circumferential direction relative to the transmission shaft 14, thereby lifting the middle plate 12 relative to the transmission shaft 14. In the illustrated example, when the sleeve 11 located at the lowered end position is rotated together with the middle plate 12 toward the payout side X along the circumferential direction relative to the transmission shaft 14, the third engagement portion 23 and the fourth engagement portion 24 engage with each other. As a result of the third engagement portion 23 and the fourth engagement portion 24 engaging with each other, when the middle plate 12 rises relative to the transmission shaft 14, the upper edge of the piercing protrusion 14c of the transmission shaft 14 is positioned at the same position in the vertical direction as or below the upper surface of the outer peripheral edge portion of the middle plate 12, as shown in Figure 6.

[0029] The third engagement portion 23 is formed in a stripe shape protruding radially outward from the outer circumferential surface of the insertion shaft 12a of the inner tray 12. The third engagement portion 23 extends upward as it approaches the payout side X along the circumferential direction. The fourth engagement portion 24 is formed in a stripe shape protruding radially inward from the inner circumferential surface of the transmission shaft 14. The fourth engagement portion 24 is located above the spiral groove 14a. The inclination angle (lead angle) of the third engagement portion 23 and the fourth engagement portion 24 with respect to the horizontal direction is larger than the inclination angle of the spiral groove 14a with respect to the horizontal direction.

[0030] Next, the function of dispensing container 1 will be described.

[0031] First, the lid 13 is rotated upward around the hinge portion 13b to open the upper end opening of the sleeve 11. Then, the sleeve 11 and the lid 13 are rotated toward the payout side X along the circumferential direction relative to the operating portion 10 and the transmission shaft 14, and the engagement protrusion 11a of the sleeve 11 is moved spirally within the spiral groove 14a of the transmission shaft 14, thereby moving the sleeve 11 downward relative to the operating portion 10, the transmission shaft 14, and the inner plate 12, and causing the rod-shaped content to protrude from the upper end opening of the sleeve 11. Here, when the sleeve 11 is rotated toward the payout side X along the circumferential direction relative to the transmission shaft 14, the sliding protrusion 11b slides on the inner surface of the operating part 10, generating a frictional force, which applies a circumferential compressive force to the elastic plate piece 11c, causing the elastic plate piece 11c to bend and deform in the radial direction.

[0032] 5, when the sleeve 11 is located at the lower end position, the first engagement portion 21 of the sleeve 11 and the second engagement portion 22 of the inner plate 12 engage with each other, restricting the relative movement in the circumferential direction between the sleeve 11 and the inner plate 12. At this time, the lower end opening edge of the upper end tubular portion 11d of the sleeve 11 abuts against the upper end opening edge of the operating part 10. When the sleeve 11, which is positioned at the lower end position, is rotated together with the middle plate 12 toward the payout side X along the circumferential direction relative to the transmission shaft 14, the third engagement portion 23 of the middle plate 12 and the fourth engagement portion 24 of the transmission shaft 14 engage with each other, causing the middle plate 12 to rise relative to the transmission shaft 14 and the sleeve 11, as shown in Figure 6. At this time, as shown by the dotted line in Figure 3, the piercing protrusion 14c of the transmission shaft 14 moves relatively within the long hole 12b of the middle plate 12 toward the opposite side of the payout side X along the circumferential direction, while the middle plate 12 pushes up the rod-shaped content, extracting the piercing protrusion 14c from the rod-shaped content.

[0033] As described above, according to the dispensing container 1 of this embodiment, when the lowered sleeve 11 is rotated together with the inner plate 12 toward the dispensing side X along the circumferential direction relative to the transmission shaft 14, the inner plate 12 rises relative to the transmission shaft 14. Therefore, it becomes possible to use the rod-shaped contents by exposing the lower end portion thereof upward from the upper end opening of the sleeve 11, and the remaining amount of the rod-shaped contents can be reduced.

[0034] A piercing projection 14c is provided on the upper end surface of the transmission shaft 14, which penetrates the inner plate 12 in the vertical direction and pierces the rod-shaped contents, making it difficult for the rod-shaped contents to break. When the lowered sleeve 11 is rotated toward the payout side X along the circumferential direction relative to the transmission shaft 14, the inner plate 12 rises relative to the sleeve 11, making it easier to remove the piercing protrusions 14c from the rod-shaped contents, thereby reliably reducing the remaining amount of rod-shaped contents.

[0035] By the third engagement portion 23 and the fourth engagement portion 24 engaging with each other, when the middle plate 12 rises relative to the transmission shaft 14, the upper edge of the piercing protrusion 14c is positioned at the same position in the vertical direction relative to the upper surface of the middle plate 12 or below it, so that when the middle plate 12 rises relative to the transmission shaft 14, the piercing protrusion 14c can be reliably removed from the rod-shaped contents.

[0036] The sleeve 11 is provided with a sliding protrusion 11b that is elastically displaceable in the radial direction and abuts against the inner surface of the operating part 10. When the sleeve 11 is rotated toward the payout side X along the circumferential direction relative to the transmission shaft 14, the sliding protrusion 11b slides against the inner surface of the operating part 10, generating a frictional force. This makes it possible to prevent the sleeve 11 from unintentionally rotating too much relative to the transmission shaft 14, and makes it easy to adjust the amount of rod-shaped content paid out.

[0037] Since the sliding protrusion 11b is formed on the cantilevered elastic plate piece 11c, when the sleeve 11 is rotated toward the payout side X along the circumferential direction relative to the transmission shaft 14, a circumferential compressive force is applied to the elastic plate piece 11c, making it easier to flex and deform the elastic plate piece 11c in the radial direction. Therefore, when a force is applied to the sleeve 11 to rotate toward the payout side X along the circumferential direction relative to the transmission shaft 14, it is possible to reliably prevent the sleeve 11 from unintentionally rotating significantly relative to the transmission shaft 14.

[0038] 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.

[0039] For example, the upper end surface of the transmission shaft 14 does not need to be provided with the piercing projection 14c. When the third engagement portion 23 and the fourth engagement portion 24 are engaged with each other, the upper edge of the piercing protrusion 14c may be positioned above the upper surface of the inner plate 12 when the inner plate 12 is raised relative to the transmission shaft 14. The sleeve 11 does not need to be provided with the sliding projection 11b and the elastic plate piece 11c.

[0040] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
