Description

The present invention relates to a dispensing container capable of dispensing rod-shaped contents, and a cartridge for the dispensing container.

A dispensing container is known that is a container for holding rod-shaped contents such as lipstick, lip balm, or stick-type glue, and is cylindrical overall in shape and includes an operating part with a bottomed, tubular skirt member, a sleeve that protrudes from the operating part along the axis of the skirt member, and a holding member that holds the contents and is provided inside the sleeve, and when the operating part is rotated relative to the sleeve, the holding member advances and the contents are dispensed from the dispensing opening of the sleeve (see, for example, Patent Document 1).

In recent years, large dispensing containers that contain cosmetics and other products in the form of rod-shaped contents have also come into use (see, for example, Patent Document 2). The dispensing container in Patent Document 2 has a rotor attached to the base (case body), and when this rotor is rotated, the rod-shaped contents contained in the base can be dispensed from an opening in the base.

JP 2013-248076 A Design Registration No. 1568492

However, the dispensing container of Patent Document 2 is simply discarded after the stored rod-shaped contents are used up. For this reason, from the perspective of resource conservation and reducing the burden on the environment, there is a demand 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.

In view of these conventional problems, the present invention aims to provide a dispensing container that allows a used cartridge to be replaced with a new cartridge, and a cartridge for the dispensing container.

The present invention provides a dispensing container comprising a base having a rotating body, and a cartridge that is attached to the base and dispenses a rod-shaped content when the rotating body is rotated,
The base is
a shaft body that rotates together with the rotating body and is movable back and forth relative to the rotating body, the shaft body having a first engagement portion and a first screw portion;
a base body having an attachment opening centered on a central axis of the rotating body and a first locking portion protruding radially inward from the attachment opening, and rotatably supporting the rotating body;
The cartridge comprises:
A middle plate that holds the rod-shaped contents and has a second engagement portion;
a cartridge body having a second screw portion and a second lock portion that engages with the first lock portion when inserted into the mounting opening and rotated around the central axis, the cartridge body surrounding the rod-shaped content and the inner tray and being attached to the base body;
The first engagement portion and the second engagement portion are detachably engaged, and the first screw-type portion and the second screw-type portion are detachably screwed together, and when the rotating body is rotated, the inner plate moves back and forth together with the shaft body, forming a dispensing container.

It is preferable that either the base body or the cartridge body has an engaging protrusion, and the other of the base body and the cartridge body has an engaging recess that engages with the engaging protrusion when the first locking portion and the second locking portion are engaged.

It is preferable that the cartridge body has a rotation stopper that contacts the first locking portion to stop the rotation of the cartridge body relative to the base body when the second locking portion is inserted into the mounting opening and rotated around the central axis.

It is preferable that the shaft body has a retaining portion that prevents the shaft body from coming out of the rotor.

a center plate side engaging portion and a cartridge body side engaging portion which engage with each other when the center plate is retracted relative to the cartridge body,
It is preferable that the middle plate side engagement portion is configured to be connected to a weakened portion provided on the middle plate and to elastically deform when the weakened portion breaks, and/or the cartridge body side engagement portion is configured to be connected to a weakened portion provided on the cartridge body and to elastically deform when the weakened portion breaks.

the first engagement portion includes a cylindrical portion extending along a central axis of the rotor and a first protrusion protruding from an inner circumferential surface of the cylindrical portion,
the second engagement portion includes a shaft-like portion that extends along a central axis of the rotor and is inserted into the cylindrical portion, and a second protrusion portion that protrudes from an outer circumferential surface of the shaft-like portion and engages with the first protrusion portion,
Furthermore, it is preferable that the cylindrical portion is provided with a slit for elastically deforming the cylindrical portion, and/or that the shaft portion is provided with a slit for elastically deforming the shaft portion.

The present invention also provides a cartridge for a dispensing container, the cartridge being attached to a base having a rotating body, and dispensing a rod-shaped content when the rotating body is rotated, comprising:
The base is
a shaft body that rotates together with the rotating body and is movable back and forth relative to the rotating body, the shaft body having a first engagement portion and a first screw portion;
The base body has an attachment opening centered on the central axis of the rotating body and a first locking portion protruding radially inward from the attachment opening, and rotatably supports the rotating body,
A middle plate that holds the rod-shaped contents and has a second engagement portion;
a cartridge body having a second screw portion and a second lock portion that engages with the first lock portion when inserted into the mounting opening and rotated around the central axis, the cartridge body surrounding the rod-shaped content and the inner tray and being attached to the base body;
The first engagement portion and the second engagement portion are detachably engaged with each other, and the first screwing portion and the second screwing portion are detachably screwed together, and the cartridge is also for a dispensing container in which the inner plate moves back and forth together with the shaft body when the rotating body is rotated.

In the dispensing container of the present invention having the above-mentioned configuration, when the rotor is rotated, the inner plate moves forward and backward together with the shaft body, so that the rod-shaped contents held in the inner plate can be dispensed and inserted from the cartridge body. The second locking part is configured to engage with the first locking part when inserted into the mounting opening and rotated around the central axis, and the first and second engagement parts are configured to detachably engage with each other, and the first and second screwing parts are configured to detachably screw with each other. Therefore, after the rod-shaped contents are used up, the cartridge attached to the base can be removed by operating the second locking part to rotate in the opposite direction to when engaged, and by operating the first and second engagement parts, and the first and second screwing parts to detach from each other. A new cartridge can also be attached to the original base in the reverse order. Furthermore, the cartridge can be composed of the inner plate and the cartridge body, and the number of parts to be discarded after the rod-shaped contents are used up can be reduced, which is excellent in terms of resource saving and reducing the burden on the environment.

Below, an embodiment of a dispensing container and a cartridge for a dispensing container (sometimes simply referred to as a cartridge in this specification) according to the present invention will be described with reference to the drawings. In the following description, the up-down direction refers to the direction along the central axis O shown in the drawings (the central axis of the rotor 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 rotating around the central axis O in this plane.

First, the structure of the dispensing container 1 shown in the figure will be described. As shown in Figures 1 and 2, the dispensing container 1 of this embodiment is composed of a base 2, a cartridge 7, and a cap 10. The base 2 is composed of a base body 3, a bottom cover 4, a rotor 5, and a shaft 6, and the cartridge 7 is composed of a cartridge body 8 and an inner plate 9. All of these components are shaped around a central axis O, and in this embodiment, all are made of synthetic resin.

The base body 3 is generally cylindrical and includes a lower outer peripheral wall 3a whose upper portion is positioned radially inward relative to the lower portion. The lower outer peripheral wall 3a has a flat shape (a track shape in this embodiment) in plan view as shown in FIG. 4. A fitting wall 3b that is thinner than the lower outer peripheral wall 3a is provided at the lower end of the lower outer peripheral wall 3a. An opening 3c that penetrates the lower outer peripheral wall 3a in the radial direction is provided at a portion located in the short direction in plan view at the vertical middle portion of the lower outer peripheral wall 3a as shown in FIG. 2.

The upper end of the lower outer peripheral wall 3a is provided with an upper wall 3d extending in the horizontal direction. The upper wall 3d is provided with a circular through hole (mounting opening 3e) centered on the central axis O as shown in FIG. 4. As shown in FIG. 1, the inner edge of the mounting opening 3e protrudes downward. As shown in FIG. 4, a pair of arc-shaped protrusions 3f, which protrude radially outward and have an arc shape in a plan view, are provided on the inner surface of the mounting opening 3e so as to face each other across the central axis O. The arc-shaped protrusions 3f correspond to the "first locking portion" in this specification. An engagement recess 3g is provided in the upper wall 3d at a portion located in the longitudinal direction in a plan view, where the upper wall 3d is recessed downward into a hemispherical shape.

The bottom cover 4 is formed in a track shape in plan view, similar to the lower outer peripheral wall 3a. The outer edge of the bottom cover 4 is provided with a fitting recess 4a that fits into the fitting wall 3b. The center of the bottom cover 4 is provided with an inner annular wall 4b that is annular.

The rotor 5 has a cylindrical wall 5a extending along the central axis O. The cylindrical wall 5a has a circular outer peripheral surface and a polygonal (e.g., regular hexagonal) inner peripheral 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 supported radially by the inner annular wall 4b. In other words, the rotor 5 is supported rotatably relative to the bottom cover 4 by the cylindrical wall 5a and the inner annular wall 4b. A stopper 5b protruding radially inward is provided above the cylindrical wall 5a.

The rotor 5 also includes an operating wall 5d that extends radially outward from the cylindrical wall 5a and then downward. The operating wall 5d is located where the opening 3c is provided, as shown in FIG. 2, and the outer circumferential surface of the operating wall 5d is exposed to the outside from the opening 3c.

The shaft body 6 has a cylindrical tubular portion 6a extending along the central axis O. The outer peripheral surface of the tubular portion 6a is provided with a male thread portion 6b extending in a spiral shape. The upper portion of the tubular portion 6a is provided with a first protrusion portion 6c protruding radially inward from the inner peripheral surface of the tubular portion 6a. The upper portion of the tubular portion 6a is provided with a pair of slits 6d that cut the tubular portion 6a from top to bottom, and the portion sandwiched between the pair of slits 6d can elastically deform radially outward. In this embodiment, the upper portion of the tubular portion 6a is provided with a pair of portions that can be elastically deformed by such slits 6d, facing each other across the central axis O.

The shaft 6 also has a plate-shaped retaining portion 6e extending radially outward from the lower end of the cylindrical portion 6a. In this embodiment, the retaining portion 6e also has a function of preventing rotation against 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 formed in a polygonal shape (a regular hexagon in this embodiment) corresponding to the shape of the inner circumferential surface of the cylindrical wall 5a. 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 hexagonal shape, and may be a triangular shape or a rectangular shape. The retaining portion 6e is also formed to a size that can be inserted inside the cylindrical wall 5a. In other words, 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 rotor 5 in the direction along the central axis O, but because the retaining portion 6e is larger than the stopper 5b, the shaft 6 will not slip out upward relative to the rotor 5.

The portion of the shaft body 6 where the cylindrical portion 6a, the first protrusion 6c, and the slit 6d are provided corresponds to the "first engagement portion" in this specification. The portion of the shaft body 6 where the cylindrical portion 6a and the male thread portion 6b are provided corresponds to the "first screw portion" in this specification.

The cartridge body 8 has a cylindrical upper outer peripheral wall 8a that has a track shape in a plan view, similar to the lower outer peripheral wall 3a shown in FIG. 4. A plate-shaped wall 8b extending horizontally is provided at the lower end of the upper outer peripheral wall 8a. A circular through hole 8c is provided in the center of the plate-shaped wall 8b, centered on the central axis O. The plate-shaped wall 8b also has a pair of elastic pieces 8d on the outer side in the longitudinal direction in a plan view from the circular through hole 8c. In this embodiment, the elastic pieces 8d are connected to the plate-shaped wall 8b at one end and are formed in a shape that extends downward from there. The elastic pieces 8d can be elastically deformed so that the portion extending downward bends radially outward. The inner surface of the portion extending downward is provided with a female screw portion 8e that extends in a spiral shape. The portion of the cartridge body 8 where the elastic pieces 8d and the female screw portion 8e are provided corresponds to the "second screw portion" in this specification.

The plate-shaped wall 8b is provided with a cylindrical peripheral wall 8f on the radially outer side of the elastic piece 8d. As shown in Figs. 5 and 7, the peripheral wall 8f is shaped to have an outer diameter slightly smaller than the inner peripheral surface of the arc-shaped protrusion 3f. As shown in Fig. 2, the lower end of the peripheral wall 8f is provided with an extension wall 8g that extends downward and has an outer diameter larger than that of the peripheral wall 8f. As shown in the figure, a concave portion 8h that opens radially outward is provided at the portion where the plate-shaped wall 8b, the peripheral wall 8f, and the extension wall 8g are connected, and the concave portion 8h engages with the arc-shaped protrusion 3f. As shown in Fig. 3, a pair of extension walls 8g are provided to face each other across the central axis O, and a pair of concave portions 8h are also provided to face each other across the central axis O. The concave portion 8h corresponds to the "second lock portion" in this specification.

The concave portion 8h is provided with a vertical rib-shaped rotation stopper 8j as shown in Figures 8, 5, and 7. The rotation stopper 8j is provided at one circumferential end of the extension wall 8g, and as described below, when the cartridge 7 is attached to the base 2 and the cartridge 7 is rotated relative to the base 2, the rotation stopper 8j comes into contact with the arc-shaped protrusion 3f to stop the rotation.

As shown in Figs. 1 and 3, the plate-shaped wall 8b has a rectangular through hole 8k that is rectangular in plan view, on the outer side of the peripheral wall 8f in the longitudinal direction in plan view. Inside the rectangular through hole 8k, a cartridge body side engaging portion 8m is provided. In this embodiment, the cartridge body side engaging portion 8m is shaped like a claw. The cartridge body side engaging portion 8m is connected to the plate-shaped wall 8b on the outer side of the longitudinal direction of the plate-shaped wall 8b, and can be elastically deformed toward the outer side in the radial direction. As shown in Fig. 3, inside the rectangular through hole 8k, a thin, narrow-width weakened portion 8n is provided, which is located in the short direction of the plate-shaped wall 8b and connects the cartridge body side engaging portion 8m and the plate-shaped wall 8b. The weakened portion 8n is breakable, and when it is broken, the cartridge body side engaging portion 8m is elastically deformable, but when the weakened portion 8n is connected to the cartridge body side engaging portion 8m and the plate-shaped wall 8b, the elastic deformation of the cartridge body side engaging portion 8m is suppressed.

The plate-shaped wall 8b has an engagement protrusion 8p that protrudes downward in a hemispherical shape at a position located in the longitudinal direction in a plan view as shown in Figures 1 and 3.

The middle plate 9 is located radially inside the upper outer peripheral wall 8a and has a plate-shaped middle plate lower wall 9a that is one size smaller than the upper outer peripheral wall 8a in a plan view. The outer edge of the middle plate lower wall 9a is provided with a middle plate outer peripheral wall 9b that extends upward along the inner peripheral surface of the upper outer peripheral wall 8a. The middle plate outer peripheral wall 9b is provided radially inside the middle plate outer peripheral wall 9b with a middle plate protruding wall 9c that extends upward. Although not shown, the middle plate 9 holds a rod-shaped content. In this embodiment, the shape of the rod-shaped content before use is such that, when the middle plate 9 is moving downward as shown in FIG. 1, the height is about the same as or lower than the upper end of the upper outer peripheral wall 8a, and the shape in a plan view is a track shape about the same as the middle plate lower wall 9a.

As shown in the partially enlarged view of FIG. 1, the lower wall 9a of the inner tray has a shaft-shaped portion 9d that extends downward along the central axis O and has a circular outer shape. The outer diameter of the shaft-shaped portion 9d is smaller than the inner diameter of the cylindrical portion 6a of the shaft body 6, as shown in FIG. 1. A second protrusion 9e that protrudes radially outward is provided on the outer peripheral surface of the shaft-shaped portion 9d.

The portion of the inner plate 9 where the shaft portion 9d and the second protrusion portion 9e are provided corresponds to the "second engagement portion" in this specification.

Furthermore, the lower wall 9a of the middle tray is provided with a middle tray side engaging portion 9f on the longitudinal outer side in a plan view with respect to the shaft-shaped portion 9d. In this embodiment, the middle tray side engaging portion 9f is shaped like a claw as shown in FIG. 1, and can be engaged with the cartridge body side engaging portion 8m.

The cap 10 has a plate-shaped top wall 10a located above the cartridge body 8, and a cap outer wall 10b that extends downward from the outer edge of the top wall 10a and surrounds the upper outer wall 8a and the upper part of the lower outer wall 3a. The cap outer wall 10b is configured to be removably fitted to the lower outer wall 3a, and the cap 10 is held by the base body 3.

Next, a method of using the dispensing container 1 will be described. Figures 1 and 2 are diagrams showing the state immediately after the cartridge 7 is attached to the base 2. When the cartridge 7 is attached to the base 2, as shown in Figures 2 and 5, the concave portion 8h engages with the arc-shaped protrusion 3f, so that the cartridge 7 does not slip out from the base 2. In this state, the engaging protrusion 8p engages with the engaging recess 3g, so that the cartridge 7 does not rotate inadvertently with respect to the base 2, and the engagement between the concave portion 8h and the arc-shaped protrusion 3f is not unintentionally released. In addition, when the cartridge 7 is attached to the base 2, the second protrusion 9e is located above the first protrusion 6c, so that the two are in a non-engaged state, while the inner plate side engaging portion 9f engages with the cartridge body side engaging portion 8m, so that the inner plate 9 does not slip out from the cartridge body 8. Furthermore, in this state, the weakened portion 8n shown in Figure 3 is connected to the cartridge body side engaging portion 8m. In other words, the elastic deformation of the cartridge body side engaging portion 8m is suppressed, and the middle plate side engaging portion 9f and the cartridge body side engaging portion 8m are more firmly engaged, so that it is possible to more reliably prevent the middle plate 9 from coming off the cartridge body 8. Also, in this state, the male thread portion 6b and the female thread portion 8e are screwed together.

Then, the rotor 5 is rotated in a direction in which the male threaded portion 6b rises relative to the female threaded portion 8e. As described above, when the rotor 5 is rotated, the shaft body 6 also rotates, and the shaft body 6 rises relative to the cartridge body 8 due to the male threaded portion 6b and the female threaded portion 8e that are screwed together. As described above, the portion sandwiched between the pair of slits 6d at the upper part of the cylindrical portion 6a can be elastically deformed radially outward. Therefore, when the shaft body 6 rises, the first protrusion 6c overcomes the second protrusion 9e and engages with it. This allows the inner plate 9 to move up and down together with the shaft body 6 in response to the rotation of the rotor 5, so that the rod-shaped contents (not shown) held in the inner plate 9 can be dispensed from the cartridge body 8 and applied to the application destination, and after application, the rod-shaped contents can be dispensed and stored inside the cartridge body 8.

When the middle plate 9 is first raised, the cartridge body side engaging portion 8m that engages with the middle plate side engaging portion 9f is also raised, so the weakened portion 8n shown in FIG. 3 breaks and the cartridge body side engaging portion 8m becomes elastically deformable. In other words, even if the middle plate 9 is lowered after the weakened portion 8n is broken and the middle plate side engaging portion 9f approaches the cartridge body side engaging portion 8m, the cartridge body side engaging portion 8m elastically deforms and becomes disengaged from the middle plate side engaging portion 9f, so the cartridge body side engaging portion 8m does not hinder the rise of the middle plate 9.

As shown in FIG. 6, after the middle plate 9 is advanced to the top end of the cartridge body 8 and the rod-shaped contents are used up, the used cartridge 7 can be replaced with a new cartridge 7. To replace the cartridge 7, the cartridge 7 is rotated relative to the base 2 as shown in FIG. 6. As a result, the recessed portion 8h that was engaged with the arc-shaped protrusion 3f as shown in FIG. 2 and FIG. 5 rotates relative to the arc-shaped protrusion 3f as shown in FIG. 7, and the engagement between the recessed portion 8h and the arc-shaped protrusion 3f is released, so that the cartridge 7 can be lifted up relative to the base 2 as shown in FIG. 8. Note that since the first protrusion 6c is engaged with the second protrusion 9e, when the cartridge 7 is lifted up, the shaft body 6 is also lifted up together with the middle plate 9. However, when the shaft body 6 is lifted up, the retaining portion 6e engages with the stopper 5b, so the shaft body 6 does not come out upward relative to the rotor 5.

As described above, the elastic piece 8d is elastically deformable so as to bend radially outward, and the portion sandwiched between the pair of slits 6d at the top of the cylindrical portion 6a is also elastically deformable radially outward. Therefore, when the cartridge 7 is pulled up relative to the base 2, the female threaded portion 8e and the male threaded portion 6b on the elastic piece 8d are disengaged from each other, and the first protrusion 6c and the second protrusion 9e on the top of the cylindrical portion 6a are also disengaged from each other, so that the inner plate 9 can be separated from the shaft 6. That is, 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 plate 9.

Figure 9 shows the state where a new cartridge 7 is attached to the base 2. The new cartridge 7 has a sheet material (not shown) attached to the upper end of the upper outer wall 8a to keep the rod-shaped contents sealed. The sheet material may be, for example, an aluminum sheet or a synthetic resin sheet. Then, with the sheet material still attached (it may be removed first), the extension wall 8g of the new cartridge 7 is inserted into the mounting opening 3e of the original base 2. Then, when the cartridge 7 is rotated relative to the base 2 as shown in Figure 10, the concave portion 8h engages with the arc-shaped protrusion 3f as shown in Figure 5, so that the cartridge 7 can be attached to the base 2. The concave portion 8h is provided with a rotation stopper 8j, and when the cartridge 7 is rotated, the rotation stopper 8j comes into contact with the arc-shaped protrusion 3f, so that the orientation of the base 2 and the cartridge 7 when mounted can be easily aligned.

Then, by peeling off the attached sheet material, it can be used as a dispensing container 1. In this way, according to the dispensing container 1 of this embodiment, the base 2 and cap 10 can be reused after the rod-shaped contents have been used, and therefore it is superior in terms of resource conservation and reduced environmental impact compared to conventional dispensing containers such as those in Patent Document 2.

Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the spirit of the present invention described in the claims unless otherwise specifically limited in the above description. For example, the configuration of the above-mentioned embodiment can be added or deleted as appropriate, and the configuration of one embodiment can be applied to other embodiments. Furthermore, the effects of the above-mentioned embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-mentioned effects.

For example, in the above-mentioned embodiment, the weakened portion 8n provided on the cartridge body 8 is connected to the cartridge body side engaging portion 8m, but a weakened portion may be provided on the inner plate 9 and this weakened portion may be connected to the inner plate side engaging portion 9f. Also, in the above-mentioned embodiment, when engaging the first protrusion 6c and the second protrusion 9e, a slit 6d is provided on the cylindrical portion 6a to elastically deform the cylindrical portion 6a, but a slit may be provided on the shaft portion 9d to elastically deform the shaft portion 9d. Also, the engaging recess 3g provided on the base body 3 may be provided on the cartridge body 8, and the engaging protrusion 8p provided on the cartridge body 8 may be provided on the base body 3.
