Description

The present invention relates to a cartridge for a dispensing container, an operating body, and a dispensing container.

BACKGROUND ART Dispensing containers are known as containers for storing stick-shaped contents such as lipstick, lip balm, or stick-type glue, and the contents can be dispensed from an upper opening by rotating a lower operating body.

In many such dispensing containers, the part that holds the contents and the operating body are inseparably connected, and after the contents are used up, they are simply discarded. However, from the viewpoint of saving resources and reducing the burden on the environment, a cartridge-type dispensing container in which the part holding the contents can be separated from the operating body has also been proposed (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 2002-34651

By the way, the cartridge of Patent Document 1 is equipped with a mechanism for feeding out the contents, and even if it is not attached to an operating body, this mechanism is activated when the lower end of the cartridge is rotated. For this reason, for example, if an external force acts on the lower end of the cartridge during transportation and causes it to rotate inadvertently, the contents may be unexpectedly drawn out.

The present invention has been made in view of these points, and an object of the present invention is to provide a cartridge for a dispensing container that can prevent the contents from being unintentionally dispensed. We also propose an operating body suitable for use with this cartridge, and a dispensing container composed of this cartridge and the operating body.

The present invention is a cartridge for a dispensing container, which is provided with a rod-shaped content and is used by being attached to an operating body of the dispensing container,
an inner plate that holds the rod-shaped content and has a protrusion on its outer peripheral surface;
an inner cylindrical body surrounding the inner plate and having a vertical groove that extends in the vertical direction and allows the protrusion to pass therethrough;
a guide cylinder that has a spiral groove that extends in a spiral shape and is engaged with the protrusion, surrounds the inner cylinder and enables rotation of the inner cylinder around an axis;
The inner cylindrical body has a protrusion that the protrusion overcomes when the inner cylindrical body is rotated in a direction in which the inner plate moves downward;
The guide cylinder has a lock groove into which the protrusion escapes from the spiral groove and enters when the inner cylinder is rotated in a direction in which the inner plate moves upward with the protrusion over the protrusion. This is a cartridge for a discharge container.

It is preferable that at least one of the protrusion and the guide cylinder has a first inclined part that is inclined in a direction around the axis and guides movement of the protrusion from the spiral groove to the lock groove.

It is preferable that at least one of the protrusion and the guide cylinder has a second inclined part that is inclined along the axis and guides movement of the protrusion from the lock groove to the spiral groove.

an outer cylindrical body that covers the outer circumferential surface of the inner cylindrical body;
It is preferable that the inner circumferential surface of the inner cylindrical body has an engaging portion that engages when the inner cylindrical body is rotated.

The present invention also provides an operating body to which the above-described cartridge for a dispensing container can be attached,
The operating body also has a push-up portion that is inserted into the inner cylindrical body during installation to push up the inner plate and move the protrusion from the lock groove to the spiral groove.

The present invention also provides a dispensing container that includes the above-described dispensing container cartridge and an operating body.

The cartridge for a dispensing container (hereinafter referred to as "cartridge") of the present invention has a protrusion on the inner cylinder and a lock groove on the guide cylinder as described above, so that the inner tray can move downward. When the inner cylinder is rotated in the opposite direction so that the protrusion on the inner plate passes over the protrusion, and the inner cylinder is further rotated in the opposite direction, the protrusion escapes from the helical groove of the guide cylinder and enters the lock groove. become. This prevents the inner tray from moving up and down even if a force to rotate the inner cylinder body is inadvertently applied, thereby preventing the contents held in the inner tray from being unintentionally drawn out.

Moreover, the inner cylinder wall 5f is provided with a vertical groove 5h that passes through the inner cylinder wall 5f. As shown in FIG. 3(b), the vertical groove 5h of this embodiment mostly extends in the vertical direction (direction along the axis O), while the upper end portion is on the left side when viewed from the outside in the radial direction toward the inside. The lower end portion extends toward the right side and then extends downward. When the inner plate 4 is attached to the inner side of the inner cylinder wall 5f, the projection 4c passes through the vertical groove 5h and projects to the outside in the radial direction of the inner cylinder wall 5f. The vertical groove 5h is formed with a width slightly larger than that of the protrusion 4c, but at its lower end there is a protrusion that narrows the width of the vertical groove 5h, as shown in the partially enlarged view of FIG. 4(b). Two protrusions 5j are provided, and the gap between the opposing protrusions 5j is narrower than that of the protrusion 4c.

The guide cylinder 6 has a generally cylindrical shape and is shaped so as to surround the inner cylinder wall 5f. When the guide cylinder 6 is attached to the inner cylinder 5, it surrounds the inner cylinder wall 5f and is held in place between the main body 5a and the claw portion 5g. On the inner circumferential surface of the guide cylinder 6, there is a guide tube extending spirally around the axis O (in this embodiment, as shown in FIG. A spiral groove 6a (which becomes a spiral) is provided. The spiral groove 6a extends in a spiral shape with a width that accommodates the protrusion 4c. Further, as shown in FIGS. 4 and 9, the guide cylinder 6 is provided on the inner circumferential surface at its lower end, adjacent to the lower end of the spiral groove 6a (in this embodiment, from the outside in the radial direction to the inside). A lock groove 6b is provided on the right side of the lower end of the spiral groove 6a when viewed from the viewpoint. As shown in FIG. 9, the side edge 6c of the lock groove 6b extends linearly along the axis O. Further, as shown in FIG. 9, between the lower end of the spiral groove 6a and the lock groove 6b, there is a guide cylinder inclined portion 6d that tilts toward the inside in the radial direction when rotating clockwise from the bottom to the top. is provided. Note that the guide cylinder inclined portion 6d is a portion referred to as a “first inclined portion” in this specification and the like.

The outer cylindrical body 7 is formed into a generally cylindrical shape, and is shaped so as to surround the guide cylinder 6 as shown in FIG. 2 . Although a detailed explanation will be omitted, the outer cylinder 7 is held in a state where it is prevented from rotating relative to the guide cylinder 6 and is prevented from coming off. An outlet 7a is provided at the upper part of the outer cylindrical body 7, through which the contents N are dispensed when the inner tray 4 is raised. Further, the lower end of the outer cylinder 7 extends to approximately the same position as the lower end of the inner cylinder 5, and covers the outer peripheral surface of the inner cylinder 5.

The ring member 8 is generally formed in a ring shape. As shown in the partially enlarged view of FIG. 1, the inner peripheral surface of the ring member 8 is provided with second ribs 8a provided at intervals in the circumferential direction. A second engagement protrusion 8b is provided that protrudes inward. Furthermore, an elastic piece 8c shaped like a claw is provided on the upper part of the ring member 8.

As shown in FIG. 2, the cartridge 102, which is composed of the inner plate 4, the inner cylinder 5, the guide cylinder 6, the outer cylinder 7, and the ring member 8, has an inner side on the radially outer side of the inner plate 4. It is assembled so that the cylinder 5, the guide cylinder 6, and the outer cylinder 7 are positioned, and the ring member 8 is positioned between the lower end of the inner cylinder 5 and the lower end of the outer cylinder 7. When the cartridge 102 is assembled, the protrusion 4c of the inner plate 4 passes through the vertical groove 5h and fits into the spiral groove 6a. Further, as shown in the partially enlarged view of FIG. 1, the second rib 8a and the second engagement protrusion 8b of the ring member 8 engage with the first rib 5d and the first engagement protrusion 5e of the inner cylinder 5, respectively. Therefore, the ring member 8 is held against the inner cylindrical body 5 so as to be non-rotatable and non-slip. Furthermore, as described above, the outer cylinder 7 is held in a state where it is prevented from rotating relative to the guide cylinder 6 and is prevented from coming off. Furthermore, the elastic piece 8c contacts the inner circumferential surface of the outer cylinder 7 with elastic force. As a result, the outer cylinder 7 and the guide cylinder 6 which is prevented from rotating by the outer cylinder 7 rotate smoothly without rattling with respect to the inner cylinder 5 and the ring member 8 which is prevented from rotating by the inner cylinder 5. be able to.

Moreover, when providing the content N in the assembled cartridge 102, the inner tray 4 is moved upward. In this case, it is preferable to use a jig J as shown in FIG. A cylindrical insertion part J1 that can be inserted into the lower end of the inner cylinder 5 is provided on the upper part of the jig J, and a jig that engages with the cartridge side rib 5b is provided on the outer peripheral surface of the insertion part J1. A rib J2 is provided. Then, the insertion part J1 is inserted into the lower end of the inner cylinder 5, and the jig J is rotated with respect to the outer cylinder 7 (in this embodiment, the jig J is rotated in a direction from below to upward with respect to the outer cylinder 7). By rotating the inner plate 4 clockwise), the inner plate 4 can be moved upward as shown in FIG. 3(a). Thereafter, the jig J is temporarily removed, and the material serving as the content is filled through the hole 4b and solidified in a predetermined shape, thereby making it possible to hold the rod-shaped content N, such as lipstick, in the inner tray 4. In this state, since the protrusion 4c is located at the upper end of the vertical groove 5h extending in the horizontal direction as shown in FIG. do not have.

After the contents N are placed in the inner tray 4, the jig J is again attached to the inner cylinder 5 as shown in FIG. 4(a). When the jig J is rotated in the direction of the arrow with respect to the outer cylinder 7 (counterclockwise in a direction from below to above with respect to the outer cylinder 7), the inner plate 4 moves downward. When the jig J is rotated to the end, the protrusion 4c moving in the vertical groove 5h climbs over the protrusion 5j and moves below the protrusion 5j, as shown in FIG. 4(b).

After that, as shown in FIG. 5(a), the jig J is rotated in the direction of the arrow with respect to the outer cylinder 7 (clockwise from below to above with respect to the outer cylinder 7). . As a result, the protrusion 4c located at the lower end of the helical groove 6a also moves in the same direction, so that the protrusion 4c escapes from the helical groove 6a and enters the lock groove 6b. FIG. 9 is a diagram schematically showing this state, where arrow A shows the state in which the projection 4c is located at the lower end of the spiral groove 6a, and arrow B shows the state in which the projection 4c moves to the lock groove 6b. This shows the state in which the As shown in the figure, the right side edge 4d that presses against the spiral groove 6a when the projection 4c leaves the spiral groove 6a is arcuate and not sharp, so when the projection 4c gets over the spiral groove 6a, the right edge 4d presses against the spiral groove 6a. can prevent damage to the Further, as shown in the figure, since a guide cylinder inclined portion 6d is provided between the lower end of the spiral groove 6a and the lock groove 6b, when the jig J is rotated, the protrusion 4c is It can be smoothly moved from the lower end to the lock groove 6b.

By the way, as shown in FIG. 9, the left side edge 4e of the projection 4c extends linearly along the axis O, and the side edge 6c of the lock groove 6b also extends linearly along the axis O. There is. Therefore, the protrusion 4c that has entered the lock groove 6b can be prevented from returning to the lower end of the spiral groove 6a.

After that, the jig J is removed from the inner cylindrical body 5. In this state, since the protrusion 4c has entered the lock groove 6b, the inner cylinder 5 does not rotate relative to the outer cylinder 7. That is, since the inner tray 4 does not move upward, it is possible to prevent the contents N from being unintentionally drawn out even when the cartridge 102 is distributed, for example. Further, in this embodiment, the outer peripheral surface of the inner cylinder 5 is covered with the outer cylinder 7, and the outer peripheral surface of the inner cylinder 5 cannot be pinched with fingers. There is no possibility that the inner cylindrical body 5 will be rotated.

To use the contents N of the cartridge 102, the cartridge 102 is attached to the operating body 101, as shown in FIG. When installed, the cylindrical wall 3b is inserted inside the inner cylinder 5, and the upper end of the cylindrical wall 3b presses against the lower surface of the inner plate main body 4a. Therefore, as shown in FIG. 7, when the cartridge 102 is pushed all the way into the operating body 101, the inner tray 4 is pushed upward by the cylindrical wall 3b. Therefore, as shown by arrow B in FIG. 9, the protrusion 4c that has entered the lock groove 6b can be moved to the spiral groove 6a as shown by arrow C. Furthermore, in this embodiment, as shown in FIG. 9, since the protrusion inclined portion 4f is provided at the upper part of the protrusion 4c, the protrusion 4c can be smoothly moved from the lock groove 6b to the spiral groove 6a.

When the cartridge 102 is attached to the operating body 101, the operating body-side engaging protrusion 3d and the cartridge-side engaging protrusion 5c engage with each other, as shown in the partially enlarged view of FIG. 1, so that the cartridge 102 is not operated during use. It will not come off accidentally from the body 101. Further, the operating body side rib 3c and the cartridge side rib 5b are engaged with each other, and the fastener 3 and the hakama member 1 are non-rotatably assembled. Therefore, when the hakama member 1 is rotated as shown in FIG. 8, the inner cylindrical body 5 is also rotated in the same direction, so that the inner tray 4 can be moved upward and the contents N can be dispensed from the outlet 7a.

After using the content N, the lifted content N is moved downward and the cover 9 is attached as shown in FIG. The cover 9 of this embodiment has a generally covered cylinder shape, and includes a disk-shaped top wall portion 9a and a cylindrical peripheral wall portion 9b that is integrally connected to the outer edge of the top wall portion 9a. It is equipped with When the cover 9 is attached, the upper end of the inner fitting 2 is lightly pressed against the inner circumferential surface of the peripheral wall part 9b, so that the cover 9 will not come off inadvertently when being carried. Furthermore, since the outlet 7a is covered by the cover 9, it is possible to prevent dust from adhering to the contents N through the outlet 7a.

Furthermore, the effects of the embodiments described above are merely illustrative of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above effects.

For example, in the present embodiment, the guide cylinder body slope part 6d is provided on the guide cylinder body 6 as the "first slope part", but the protrusion 4c may be provided with something corresponding to the guide cylinder body slope part 6d. Moreover, the protrusion inclined part 4f provided on the protrusion 4c as a "second inclined part" may be provided with a corresponding one on the guide cylinder body 6. Further, in this embodiment, the cartridge-side rib 5b is provided on the inner peripheral surface of the inner cylinder 5 as an "engaging portion", but the engaging portion is not limited to one that protrudes from the inner peripheral surface like a rib. It may also be a groove with a concave inner circumferential surface.
