Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, the dispensing container described in Patent Document 2 is discarded after the contained rod-shaped contents have been used up. Therefore, from the viewpoint of resource conservation and reduction of environmental burden, there is a need for a dispensing container in which some components such as the base can be reused, and in which a used cartridge containing the used rod-shaped contents can be replaced with a new cartridge.

[0006] In view of these conventional problems, the present invention aims to provide a dispensing container that allows used cartridges to be replaced with new cartridges, and a cartridge for the dispensing container. [Means for solving the problem]

[0007] The present invention relates to a dispensing container comprising a base having a rotating body and a cartridge mounted on the base from which a rod-shaped contents are dispensed when the rotating body is rotated, The aforementioned base is A shaft body that rotates together with the rotating body and is movable forward and backward relative to the rotating body, having a first engaging portion and a first screwed portion, The base body comprises a base-side outer peripheral wall into which the cartridge is inserted, and a first locking portion, and rotatably supports the rotating body. The aforementioned cartridge is A middle tray that holds the rod-shaped contents and has a second engaging portion, The cartridge body is configured to surround the rod-shaped contents and the inner tray and to be inserted into the outer peripheral wall of the base side, and comprises a second screw portion and a second locking portion that engages with the first locking portion when inserted into the outer peripheral wall of the base side, The first engaging portion and the second engaging portion are detachably engaged, and the first threaded portion and the second threaded portion are detachably screwed together. 、 The cartridge body is held in place on the base body by the engagement of the first locking portion and the second locking portion, and the first engaging portion and the second engaging portion are configured to be disengaged and the first threaded portion and the second threaded portion are threaded together. As the rotating body rotates, the shaft advances relative to the rotating body, causing the first engaging portion and the second engaging portion to engage. This is a dispensing container in which the inner tray moves back and forth together with the shaft.

[0008] Preferably, the cartridge body has a cartridge-side outer wall that surrounds the rod-shaped contents and the inner tray and is inserted into the base-side outer wall, and a flange that protrudes outward from the outer surface of the cartridge-side outer wall above the base-side outer wall.

[0009] Preferably, the base body has a notch in which the outer peripheral wall on the base side is cut out from above to expose the outer peripheral wall on the cartridge side.

[0010] Preferably, the shaft has a retaining portion that prevents the shaft from coming out of the rotating body.

[0011] The first engaging portion comprises a cylindrical portion extending along the central axis of the rotating body and a first projection protruding from the inner circumferential surface of the cylindrical portion. The second engaging portion comprises a shaft-shaped portion that extends along the central axis of the rotating body and is inserted into the cylindrical portion, and a second projection that protrudes from the outer circumferential surface of the shaft-shaped portion and engages with the first projection. Furthermore, it is preferable to provide a slit that cuts out the cylindrical portion to cause elastic deformation of the cylindrical portion, and / or a slit that cuts out the shaft portion to cause elastic deformation of the shaft portion.

[0012] Furthermore, the present invention relates to a cartridge for a dispensing container, which is mounted on a base equipped with a rotating body, and when the rotating body is rotated, a rod-shaped contents are dispensed. The aforementioned base is A shaft body that rotates together with the rotating body and is movable forward and backward relative to the rotating body, having a first engaging portion and a first screwed portion, The device is configured to include a base body that rotatably supports the rotating body, having a base-side outer peripheral wall into which the cartridge for the dispensing container is inserted, and a first locking portion, A middle tray that holds the rod-shaped contents and has a second engaging portion, The cartridge body is configured to surround the rod-shaped contents and the inner tray and to be inserted into the outer peripheral wall of the base side, and comprises a second screw portion and a second locking portion that engages with the first locking portion when inserted into the outer peripheral wall of the base side, The first engaging portion and the second engaging portion are detachably engaged, and the first screwing portion and the second screwing portion are detachably screwed, and 、 The cartridge body is held in place on the base body by the engagement of the first locking portion and the second locking portion, and the first engaging portion and the second engaging portion are configured to be disengaged and the first threaded portion and the second threaded portion are threaded together. As the rotating body rotates, the shaft advances relative to the rotating body, causing the first engaging portion and the second engaging portion to engage. It is also a cartridge for a feeding container in which the middle plate moves forward and backward together with the shaft body.

Effects of the Invention

[0013] In the feeding container of the present invention having the above-described configuration, when the rotating body is rotated, the middle plate moves forward and backward together with the shaft body, so that the rod-shaped contents held on the middle plate can be fed out or fed into the cartridge body. When the cartridge body is inserted into the outer peripheral wall on the base side, the first locking portion and the second locking portion are configured to engage with each other. Further, the first engaging portion and the second engaging portion are detachably engaged, and the first screwing portion and the second screwing portion are detachably screwed. Therefore, after the rod-shaped contents are used up, the cartridge body is removed from the outer peripheral wall on the base side, and the first engaging portion and the second engaging portion, and the first screwing portion and the second screwing portion are operated to disengage, so that the cartridge mounted on the base can be removed. Also, a new cartridge can be mounted on the original base in the reverse procedure. Furthermore, the cartridge can be composed of a middle plate and a cartridge body, and the number of members to be discarded after the rod-shaped contents are used up can be reduced, so that it is excellent in resource saving and reduction of environmental load.

[Figure 7] This is a half-cross-sectional view showing a modified example of the dispensing container shown in Figure 1. [Modes for carrying out the invention]

[0015] Hereinafter, an embodiment of the dispensing container and the cartridge for the dispensing container (sometimes simply referred to as the cartridge in this specification) according to the present invention will be described with reference to the drawings. In the following description, the vertical direction refers to the direction along the central axis O shown in the drawings (the central axis of the rotating body 5 described below). The radial direction refers to the direction perpendicular to the central axis O in a plane perpendicular to the central axis O, and the circumferential direction refers to the direction of rotation around the central axis O in this plane.

[0016] First, let's explain the configuration of the illustrated dispensing container 1. As shown in Figures 1 and 2, the dispensing container 1 of this embodiment consists of a base 2, a cartridge 7, and a cap 10. The base 2 consists of a base body 3, a bottom cover 4, a rotating body 5, and a shaft 6, and the cartridge 7 consists of a cartridge body 8 and an inner tray 9. All of these components are shaped around a central axis O, and in this embodiment, all are made of synthetic resin.

[0017] The base body 3 is equipped with a cylindrical lower outer peripheral wall 3a. The lower outer peripheral wall 3a has a flattened shape (track shape in this embodiment) in plan view. A fitting wall 3b, which is thinner than the lower outer peripheral wall 3a, is provided at the lower end of the lower outer peripheral wall 3a. In the middle of the lower outer peripheral wall 3a in the vertical direction, in a plan view, there is an opening 3c that penetrates the lower outer peripheral wall 3a radially, as shown in Figure 2.

[0018] The base body 3 also has a cylindrical base-side outer wall 3d that is smaller in diameter than the lower outer wall 3a and extends upward from the upper end of the lower outer wall 3a. In a plan view, the upper end of the base-side outer wall 3d, located in the longitudinal direction, is provided with a notch 3e that cuts out the base-side outer wall 3d in a semicircular shape from top to bottom (see Figure 5). The inner surface of the lower outer wall 3a is provided with an upper wall 3f that extends radially inward, and the central part of the upper wall 3f is provided with an opening 3g that penetrates the upper wall 3f and an annular wall 3h that surrounds the opening 3g and extends downward.

[0019] Furthermore, the base body 3 is provided with a through hole 3j located in the longitudinal direction in a plan view, which penetrates the upper wall 3f. The through hole 3j corresponds to the "first locking part" in this specification, etc.

[0020] The bottom cover 4, like the lower outer peripheral wall 3a, is shaped like a track in plan view. The outer edge of the bottom cover 4 is provided with a fitting recess 4a that fits into the fitting wall 3b. The central part of the bottom cover 4 is provided with an inner annular wall 4b that forms an annular shape.

[0021] The rotating body 5 is provided with a cylindrical wall 5a that extends along the central axis O. The cylindrical wall 5a has a circular outer surface and a polygonal (e.g., regular hexagonal) inner surface. The outer diameter of the cylindrical wall 5a is slightly smaller than the inner diameter of the inner annular wall 4b, and the cylindrical wall 5a is radially supported by the inner annular wall 4b. That is, the rotating body 5 is rotatably supported relative to the bottom cover 4 by the cylindrical wall 5a and the inner annular wall 4b. Above the cylindrical wall 5a, there is a stopper 5b that protrudes radially inward. Above the stopper 5b, there is an annular regulating wall 5c.

[0022] The rotating body 5 also includes an operating wall 5d that extends radially outward from the cylindrical wall 5a and then downward. As shown in Figure 2, the operating wall 5d is located where the opening 3c is provided, and the outer surface of the operating wall 5d is exposed to the outside through the opening 3c.

[0023] The shaft body 6 has a cylindrical tubular portion 6a that extends along the central axis O. A spirally extending male thread portion 6b is provided on the outer circumferential surface of the tubular portion 6a. A first projection 6c is provided at the upper part of the tubular portion 6a that protrudes radially inward from the inner circumferential surface of the tubular portion 6a. A pair of slits 6d are provided at the upper part of the tubular portion 6a that cut out the tubular portion 6a from top to bottom, and the portion sandwiched between the pair of slits 6d can be elastically deformed radially outward. In this embodiment, a pair of such elastically deformable portions by slits 6d are provided at the upper part of the tubular portion 6a so as to face each other across the central axis O.

[0024] The shaft 6 also has a plate-shaped retaining portion 6e that extends radially outward from the lower end of the cylindrical portion 6a. In this embodiment, the retaining portion 6e also has the function of preventing rotation relative to the inner circumferential surface of the cylindrical wall 5a. In order to provide the rotation prevention function, the retaining portion 6e in this embodiment is shaped like a polygon (a regular hexagon in this embodiment) corresponding to the shape of the inner circumferential surface of the cylindrical wall 5a. Note that the shape of the inner circumferential surface of the cylindrical wall 5a and the shape of the retaining portion 6e are not limited to a regular hexagon, but may be triangular or quadrilateral. The retaining portion 6e is also shaped to be inserted inside the cylindrical wall 5a. That is, when the rotating body 5 is rotated with the retaining portion 6e inserted inside the cylindrical wall 5a, the shaft 6 rotates together with the rotating body 5. In this state, the shaft 6 can move relative to the rotating body 5 in a direction along the central axis O, but since the retaining portion 6e is larger than the stopper 5b, the shaft 6 will not come out upward relative to the rotating body 5.

[0025] The cylindrical portion 6a, the first projection 6c, and the slit 6d on the shaft 6 correspond to the "first engaging portion" as defined in this specification. The cylindrical portion 6a and the male threaded portion 6b on the shaft 6 correspond to the "first screwing portion" as defined in this specification.

[0026] The cartridge body 8 is provided with a cylindrical cartridge-side outer wall 8a that, in plan view, is a track shape slightly smaller than the base-side outer wall 3d. A plate-shaped wall 8b extending horizontally is provided at the lower end of the cartridge-side outer wall 8a. A circular through hole 8c centered on the central axis O is provided in the center of the plate-shaped wall 8b. The plate-shaped wall 8b is also provided with a pair of elastic pieces 8d extending longitudinally outward from the circular through hole 8c in plan view. In this embodiment, one end of the elastic piece 8d is connected to the plate-shaped wall 8b and is shaped to extend downward from there. The elastic piece 8d is also elastically deformable so that the portion extending downward bends radially outward. Furthermore, a spirally extending female screw portion 8e is provided on the inner circumferential surface of this downward-extending portion. The portion of the cartridge body 8 where the elastic piece 8d and the female screw portion 8e are provided corresponds to the "second screw portion" in this specification.

[0027] Furthermore, the plate-like wall 8b is provided with a rectangular through-hole 8f, which is rectangular in shape in a plan view, located longitudinally outward in a plan view relative to the elastic piece 8d. Inside the rectangular through-hole 8f, a cartridge body-side engaging portion 8g is provided. In this embodiment, the cartridge body-side engaging portion 8g is shaped like a claw, as shown in the figure. The cartridge body-side engaging portion 8g is connected to the plate-like wall 8b on its longitudinally outward side and is elastically deformable radially outward. Although not shown in the figure, a thin, narrow, weakened portion is provided inside the rectangular through-hole 8f, located in the short direction of the plate-like wall 8b, connecting the cartridge body-side engaging portion 8g and the plate-like wall 8b. The weakened portion is breakable, and in the broken state, the cartridge body-side engaging portion 8g is elastically deformable; however, when the weakened portion is connected to the cartridge body-side engaging portion 8g and the plate-like wall 8b, the elastic deformation of the cartridge body-side engaging portion 8g is suppressed.

[0028] Furthermore, the plate-like wall 8b has a claw-shaped portion 8h on its lower surface located above the through hole 3j, which protrudes downward and whose inner circumferential surface protrudes radially inward. As shown in the figure, the claw-shaped portion 8h engages with the through hole 3j.

[0029] Furthermore, the upper end of the outer peripheral wall 8a on the cartridge side is provided with a flange 8k that extends radially outward. In this embodiment, the flange 8k is provided over the entire circumferential area of ​​the outer peripheral wall 8a on the cartridge side.

[0030] The portion of the cartridge body 8 where the elastic piece 8d and the female thread portion 8e are provided corresponds to the "second threaded portion" in this specification, etc. The claw-shaped portion 8h corresponds to the "second locking portion" in this specification, etc.

[0031] The inner tray 9 is located radially inward of the cartridge-side outer peripheral wall 8a and has a plate-shaped lower inner tray wall 9a that is slightly smaller than the cartridge-side outer peripheral wall 8a in plan view. The outer edge of the lower inner tray wall 9a is provided with an outer peripheral tray wall 9b that extends upward along the inner peripheral surface of the cartridge-side outer peripheral wall 8a. Radially inward of the outer peripheral tray wall 9b is provided with an inner inner tray wall 9c that extends upward. Although not shown in the figures, the inner tray 9 holds a rod-shaped contents. In this embodiment, the shape of the rod-shaped contents before use, as shown in Figure 1, when the inner tray 9 is moved downward, is such that its height is about the same as or lower than the upper end of the cartridge-side outer peripheral wall 8a, and its shape in plan view is a track shape similar to the lower inner tray wall 9a.

[0032] As shown in the enlarged section of Figure 1, the lower wall 9a of the inner tray has an axial portion 9d that extends downward along the central axis O and has a circular outer shape. As shown in Figure 1, the outer diameter of the axial portion 9d is smaller than the inner diameter of the cylindrical portion 6a of the shaft body 6. A second projection 9e is provided on the outer circumferential surface of the axial portion 9d, projecting radially outward.

[0033] Furthermore, the portion of the inner plate 9 where the axial portion 9d and the second projection 9e are provided corresponds to the "second engagement portion" in this specification, etc.

[0034] Furthermore, the lower wall 9a of the inner tray is provided with an inner tray-side engaging portion 9f on the longitudinally outward side in a plan view relative to the axial portion 9d. As shown in Figure 1, the inner tray-side engaging portion 9f of this embodiment is shaped like a claw and can be engaged with the cartridge body-side engaging portion 8g.

[0035] The cap 10 comprises a plate-shaped top wall 10a located above the cartridge body 8, and a cap outer peripheral wall 10b extending downward from the outer edge of the top wall 10a and surrounding the cartridge-side outer peripheral wall 8a, etc. The cap outer peripheral wall 10b is configured to be detachably fitted onto the lower outer peripheral wall 3a, and the cap 10 is held by the base body 3.

[0036] Next, the method of using the dispensing container 1 will be explained. Figures 1 and 2 show the state immediately after the cartridge 7 is mounted on the base 2. When the cartridge 7 is mounted on the base 2, as shown in Figure 1, the claw-shaped portion 8h is engaged with the through hole 3j, so the base 2 can hold the cartridge 7. Also, when the cartridge 7 is mounted on the base 2, the second projection 9e is located above the first projection 6c and the two are not engaged, while the inner tray side engaging portion 9f is engaged with the cartridge body side engaging portion 8g, so the inner tray 9 will not come out of the cartridge body 8. Furthermore, in this state, the cartridge body side engaging portion 8g is connected to the plate-shaped wall 8b via the weakened portion described above. That is, the elastic deformation of the cartridge body side engaging portion 8g is suppressed, and the inner tray side engaging portion 9f and the cartridge body side engaging portion 8g are more firmly engaged, so the inner tray 9 can be more reliably prevented from coming out of the cartridge body 8. In this state, the male thread portion 6b and the female thread portion 8e are screwed together. Furthermore, the lower end of the elastic piece 8d is located radially inward of the restricting wall 5c, and the radially outward elastic deformation of the elastic piece 8d is restricted by the restricting wall 5c.

[0037] Next, the rotating body 5 is rotated in a direction such that the male threaded portion 6b rises relative to the female threaded portion 8e. As described above, when the rotating body 5 is rotated, the shaft body 6 also rotates, so the shaft body 6 rises relative to the cartridge body 8 due to the screwing male threaded portion 6b and female threaded portion 8e. As described above, the portion sandwiched between the pair of slits 6d at the top of the cylindrical portion 6a is elastically deformable radially outward. Therefore, as the shaft body 6 rises, the first projection 6c overcomes the second projection 9e and engages with it. As a result, the inner tray 9 can be moved up and down together with the shaft body 6 in accordance with the rotation of the rotating body 5, so that the rod-shaped contents (not shown) held in the inner tray 9 can be fed out from the cartridge body 8 and applied to the application surface, and after application, the rod-shaped contents can be fed back and housed inside the cartridge body 8.

[0038] Furthermore, when the inner tray 9 first rises, the cartridge body side engaging portion 8g, which engages with the inner tray side engaging portion 9f, is also pulled up. As a result, the weakened portion connecting the cartridge body side engaging portion 8g and the plate-like wall 8b breaks, and the cartridge body side engaging portion 8g becomes elastically deformable. In other words, even after the weakened portion breaks, when the inner tray 9 is lowered and the inner tray side engaging portion 9f approaches the cartridge body side engaging portion 8g, the cartridge body side engaging portion 8g elastically deforms and becomes disengaged from the inner tray side engaging portion 9f. Therefore, the cartridge body side engaging portion 8g does not hinder the rise of the inner tray 9.

[0039] As shown in Figure 3, after extending the inner tray 9 to the upper end of the cartridge body 8 and using up the rod-shaped contents, the used cartridge 7 can be replaced with a new cartridge 7. To replace it, place your fingers on the cartridge 7 and apply upward force. This releases the engagement between the claw-shaped portion 8h and the through hole 3j, allowing the cartridge 7 to be pulled up relative to the base 2. The cartridge 7 in this embodiment is equipped with a flange 8k that extends radially outward, and when pulling up the cartridge 7, you can place your fingers on this flange 8k. Furthermore, as shown in Figure 5, the base 2 in this embodiment is equipped with a notch 3e at the upper end of the base-side outer peripheral wall 3d located in the longitudinal direction in a plan view, and since the cartridge-side outer peripheral wall 8a is exposed from this notch 3e, you can place your fingers on the flange 8k while holding down the exposed cartridge-side outer peripheral wall 8a with your fingers. Therefore, the cartridge 7 can be securely held with your fingers, making it easier to pull up the cartridge 7. Furthermore, when the cartridge 7 is started to be pulled up, the lower end of the elastic piece 8d rises above the regulating wall 5c, so the elastic piece 8d becomes capable of elastically deforming radially outward. Also, as described above, the first projection 6c is engaged with the second projection 9e, so when the cartridge 7 is pulled up, the shaft 6 is also pulled up along with the inner tray 9. However, when the shaft 6 is pulled up, the retaining part 6e engages with the stopper 5b, so the shaft 6 does not come out upward relative to the rotating body 5.

[0040] As described above, the elastic piece 8d is elastically deformable so as to bend radially outward, and the portion of the cylindrical part 6a sandwiched between the pair of slits 6d at the top is also elastically deformable radially outward. Therefore, by pulling the cartridge 7 up relative to the base 2, the engagement between the female threaded portion 8e and the male threaded portion 6b on the elastic piece 8d is released, and the engagement between the first projection 6c and the second projection 9e on the top of the cylindrical part 6a is also released, so that the inner tray 9 can be separated from the shaft 6 as shown in Figures 4 and 5. In other words, in the dispensing container 1 of this embodiment, the only components that can be removed from the base 2 as the cartridge 7 are the cartridge body 8 and the inner tray 9.

[0041] Figure 6 shows the state in which a new cartridge 7 is attached to the base 2. The new cartridge 7 has a sheet material S attached to the upper end of the outer peripheral wall 8a of the cartridge side in order to keep the rod-shaped contents sealed. The sheet material S may be made of aluminum or synthetic resin, for example. Then, with the sheet material S attached (or it may be removed first), the new cartridge 7 is inserted into the original base body 3. As the cartridge 7 is moved downward relative to the base body 3, the claw-shaped part 8h engages with the through hole 3j, so that the cartridge 7 can be attached to the base 2.

[0042] Afterward, the dispenser can be used as a dispensing container 1 by peeling off the attached sheet material S. Thus, with the dispensing container 1 of this embodiment, the base 2 and cap 10 can be reused after the rod-shaped contents have been used, making it superior to conventional dispensing containers such as those described in Patent Document 2 in terms of resource conservation and reduction of environmental burden.

[0043] Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiments, and unless otherwise specifically limited in the above description, various modifications and changes are possible within the scope of the spirit of the present invention as described in the claims. For example, the configurations of the embodiments described above can be added or deleted as appropriate, and the configuration of one embodiment can be provided in other embodiments. Furthermore, the effects in the embodiments described above are merely illustrative of the effects that may arise from the present invention, and do not mean that the effects of the present invention are limited to the effects described above.

[0044] For example, in the embodiment described above, the notch 3e is provided at the upper end of the base-side outer peripheral wall 3d, located in the longitudinal direction in a plan view, as shown in Figure 5. However, the position can be changed as appropriate, and it may also be provided at the upper end of the base-side outer peripheral wall 3d, located in the short direction in a plan view, as shown in Figure 7. Furthermore, the shape of the notch 3e is not limited to a semicircular shape, but may be a rectangular shape or other shape.

[0045] Furthermore, in the above-described embodiment, the weakening portion provided on the cartridge body 8 was connected to the cartridge body side engaging portion 8g, but the weakening portion may be provided on the inner tray 9 and this weakening portion may be connected to the inner tray side engaging portion 9f. Also, in the above-described embodiment, when engaging the first projection 6c and the second projection 9e, a slit 6d was provided in the cylindrical portion 6a to cause elastic deformation of the cylindrical portion 6a, but the slit may be provided in the shaft portion 9d to cause elastic deformation of the shaft portion 9d. Also, in the above-described embodiment, a through hole 3j was used as the first locking portion and a claw-shaped portion 8h was used as the second locking portion, but the claw-shaped portion 8h may be used as the first locking portion and the through hole 3j may be used as the second locking portion.
