[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container in which the contents of various stick-shaped cosmetic containers can be replaced.

[0002]

2. Description of the Related Art In a conventional cosmetic container, when the contents are set in the container, about 20% of defective products are generated due to damage to the contents or the like. Since it was not possible to replace the contents, all the damaged contents were discarded, which was a great waste of resources.

[0003]

In order to solve these problems, a replaceable container is used as a replaceable container.
No. 1-194425 has been proposed, but since the present invention is a screw type, it takes time to release and the operability is poor,
It was often returned when removing it, and the contents were damaged. Further, Japanese Patent Application Laid-Open No. 2001-327330 proposes "a middle dish of a stick-shaped cosmetic material feeding container". However, in order to remove the inner dish, this invention requires that a separate jig is provided. However, the operability was poor. Therefore, a container in which the inner plate can be released by extending the normal feeding operation has been desired.

[0004]

In order to solve the above-mentioned problems, the replaceable rod-shaped delivery container of the present invention is a rod-shaped delivery container having a structure in which a drive means is used to take contents in and out from a casing. A tubular member having an extending groove, a middle plate that holds the contents set inside the tubular member so as to be movable along the groove, and a main member releasably attached to the middle plate, and the tubular member The rotating member has a large-diameter spiral groove formed on the inner circumference and is rotatable relative to the tubular member, and the main member has a locking means and a middle member that engage with the axially extending groove. There is a releasing means for releasing the assembling with the dish, the inner tray and the main member move together upward from the beginning of use, and the releasing means provided on the main member and the locking provided on the tubular member. The point where the means is engaged is the maximum feeding position. By further rotation, the releasing means is released, and summarized in that the inner plate detached from the driven member.

Further, the gist of the present invention is that the locking means is constituted by a rotation projection and lateral grooves provided at the upper and lower ends of the groove extending in the axial direction.

Further, the releasing means is composed of a releasing projection and lateral grooves provided at the upper and lower ends of the groove extending in the axial direction, and the length of the lateral groove for the locking means for restricting the rotating operation is set. The gist is that it is made longer than the length of the lateral groove for the releasing means.

Another feature of the replaceable rod-shaped delivery container of the present invention is that two types of grooves extending in the axial direction are provided to restrict the release protrusion and the rotation protrusion.

[0008] Finally, in the method of replacing the contents of a rod-shaped feeding container according to the present invention, a tubular member having a groove extending in the axial direction, and contents set inside the tubular member so as to be movable along the groove. An inner plate for holding an object, a main member releasably attached to the inner plate, and a rotating member having a diameter larger than that of the tubular member and having a spiral groove formed on the inner periphery thereof so as to be rotatable relative to the tubular member. And a structure in which the drive member has a driving means having a locking means for engaging with the groove extending in the axial direction and a releasing means for releasing the assembly with the inner plate. The method of replacing the contents in the rod-shaped delivery container according to claim 1, wherein the releasing means provided on the inner plate for both of the main member that moves together with the inner plate maximizes the contents up to the point where the locking means of the tubular member regulates the releasing means. Unrolling, then further rotation Releasing the assembly of a main member inner tray further, by leaving from the main member of the contents, and summarized in that the contents removed from the inner tray per container.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention makes it possible to easily replace the contents with a small number of parts regardless of the method for filling the contents in the cosmetic container. That is, when the content is, for example, a lipstick, there are various types of delivery lipstick containers such as a thin type, a thick type, an insertion method, a filling method (top filling method, bottom filling method). It can also be applied to the type of lipstick. A cosmetic container comprising a middle plate for holding contents, a main member assembled to the bottom part of the middle plate, a cylindrical member provided outside thereof, a spiral rotor having a spiral groove formed inside, and a case. The feeding and releasing mechanism of the present invention is performed by providing a groove in the axial direction in the tubular member, and providing locking means and releasing means capable of locking in the groove. The locking means is generally composed of protrusions and grooves, but is not limited to this. The releasing means and the assembling means may be various ones such as engagement by a claw, engagement between projections, engagement between a projection and a groove, and pressing of a projection, but the assembly is released by extension of the rotation operation. Any method may be used as long as the axial groove of the tubular member is not necessarily used. When the protrusion is used as the releasing means, the force required for releasing and the time required for the releasing operation can be adjusted by devising the type and shape of the protrusion. FIG. 8 exemplifies the kinds of protrusions by the cross-sectional view taken along the line BB of FIG. The protrusion of (a) is provided with a large rising angle of the protrusion portion, and a relatively strong force is required, and the protrusion of (b) can be released with a weaker force than the protrusion of (a). Further, in the case of the protrusion as shown in (c), since the rising surface of the protrusion forms a gentle inclined surface, the releasing operation will be performed gently and the releasing may be performed in the middle of the inclined surface. , There will be little resistance to the release operation. In the case of using the groove, first, one groove is provided, and a lateral groove that restricts the rotation projection that meshes with the spiral of the rotating member and a lateral groove that restricts the release projection of the assembly portion of the main member are provided at the upper and lower ends thereof. It is conceivable to provide two grooves symmetrically. Next, two kinds of grooves are provided, and the upper and lower ends of the groove and the release protrusion of the assembly portion of the main member are regulated. It is also possible to provide a lateral groove. Furthermore, it is also possible to provide two grooves of these two types symmetrically. When two symmetrically arranged pieces are provided in this manner, the feeding and rotating operation of the contents can be stably performed. However, when the number of grooves is large, the strength of the tubular member is weakened. It is preferable to provide one groove or two kinds of grooves. Further, a method of regulating two kinds of protrusions with one groove without providing symmetrical grooves is also simple.

FIG. 5 is a cross-sectional view with a case showing a middle plate replacement position and a side view of a tubular member. In the container of the present invention, a main member (2) having an inner plate (1) shown in FIG. 2 (a) and an assembling portion (3) to be combined with an assembling claw (5) provided on the inner wall below the inner plate is a tubular member. (4)
The vertical movement and the inner plate releasing operation are performed by being regulated by the groove. The release protrusion (11) of the main member is the rotation protrusion (10).
It is set shorter. The cylindrical member (4) has a vertical groove (4
Two a) are provided at symmetrical positions, and one of them is a groove (4b) having an open upper part. This is because it is necessary to insert the leading member having the protrusion into the tubular member (from above). Further, lateral grooves (6) (8) with which the release projections (11) engage and lateral grooves (7) (9) with which the projections (10) engage are provided at the upper and lower ends of the groove. The lateral groove (9) is set to be longer than the lateral groove (8) in the upper lateral direction. Due to the difference in the length of the groove, the inner plate can be removed. It should be noted that the rotation projection projects more outward than the release projection of the main member, and the release for removing the contents of the present invention is caused by the difference in the projection degree and the length of the lateral groove with which they engage. Forming the mechanism.

The actual operation is as follows. First, as shown in FIG. 2 (a), an assembling claw (5) is provided inside the lower part of the inner plate (1) holding the lipstick (19), and the lower tip has an obliquely cut shape. It is adapted to be assembled with the assembling reverse claw (5a) on the lead member side. The leading member (2) is open at the top and has a hollow upper half structure. As shown in FIG. 2 (f), the hollow upper half portion is bent toward the hollow side (inside). Is the assembly part (3). At the center of the assembly portion (3), there is provided a releasing projection (11) used to release the assembly claw by causing a bending, and in the assembled state, the projection upper part ( 11a) also holds the lowermost portion (1a) of the middle plate. As shown in FIG. 2A, the protrusion degree of the protrusion is set so as to slightly protrude from the outer wall surface of the inner plate (1) to the outside in the assembled state. Further, the rotation protrusion is set to have a longer protrusion than the release protrusion,
As shown in FIG. 2 (d), the length is set so that it can be engaged with the spiral groove (13) of the spiral rotating body (12). Now, the rotation projection (10) engages with the vertical groove (4a) and the horizontal grooves (7) (9) of the tubular member (4), and further engages with those grooves to allow the spiral rotor (12) to rotate. Engage in the spiral groove (13).
On the other hand, the release projection (11) engages with the vertical groove (4a) and the horizontal grooves (6) (8) of the tubular member (4). Since the release projection has a short projection length, it is similar to the rotation projection in that the spiral rotor (1
It does not engage the spiral groove (13) of 2). The state in which the lipstick has rolled down most is shown in FIGS. 3 (a) and 3 (b). At this time, the release projection (11) is located at the lower lateral groove (6) and the rotation projection is located at the lower lateral groove (7). Next, when the lipstick is fed, the rotation protrusion is pulled up by the spiral groove and moves upward together with the inner plate holding the lipstick. The release projection / rotation projection passes through the vertical groove (4a) of the tubular member (4) and rises upward, and further rotation causes the upper lateral groove (8).
Engage with (9). At this time, since the lateral groove (8) for the release projection is shorter than the lateral groove (9) for the rotation projection,
When the maximum feeding position (Fig. 4) is exceeded, as shown in Fig. 5 (a), the releasing projection (11) is pushed over the releasing lateral groove (8) and pushed by the inner wall of the tubular member to inward. The assembling part (3) bends, and the engagement between the assembling claw (5) and the assembling reverse claw (5a) on the main member side is released. In addition, when assembling the inner plate, the inner plate is pressed against the main member at the maximum feeding position while checking for a clicking sound. Alternatively, it is possible to confirm the assembly by pulling in the content by trying the operation of assembling and retracting the content at the release position. When such a container is used, the contents can be easily taken out, so that even if a defective product occurs in the manufacturing process, the contents can be replaced, which is useful for effective use of resources. It is also possible to replace a new product with the contents that have been used up.

Second Embodiment A second embodiment of the present invention will be described with reference to FIGS. 6A is a perspective view of the main member of the present embodiment, FIG. 6B is a plan view, and FIG. 6C is A- of FIG. 6A.
FIG. (D) is a partially cutaway sectional view of a filling medium tray. FIG. 7 is a front view of the tubular member in this embodiment. In the figure, the rotation projection (20) and the release projection (21) are provided slightly displaced, and the restriction grooves corresponding to them are (24a) and (25) in FIG.

The actual operation of the container having such a structure is as follows. First, as shown in FIG. 6 (d), an assembling claw (15) is provided on the inner side of the lower portion of the middle plate (1 ') holding the contents, and the lower tip has an obliquely cut shape. Reverse claw for assembly on the main member side (25
It is designed to be assembled with a). The leading member (22) is open at the top and has a hollow upper half structure, and the hollow upper half portion bends toward the hollow side (inside), and this portion is used as an assembly portion (23). At the center of the assembly portion (23), a releasing projection (21) used to release the assembly claw by causing bending.
Are provided toward the outside. As in the case of the first embodiment, the protrusion degree of the protrusion is set to slightly protrude from the outer wall surface of the inner plate (1 ′) in the assembled state. Further, the protrusion for rotation is set to have a longer degree of protrusion than the release protrusion, and the spiral groove (not shown) of the spiral rotor is provided.
Is set so that it can be engaged with. Now, the rotation protrusion (20) is provided with the vertical groove (24a) and the horizontal groove (27) of the tubular member.
While engaging with (29) and further engaging with those grooves,
Engages in the spiral groove of the spiral rotor. On the other hand, the release protrusion (21)
Engages the longitudinal grooves (25) and the lateral grooves (26) (28) of the tubular member. Since the releasing projection has a short projecting length, it does not engage with the spiral groove of the spiral rotating body unlike the rotating projection. In the state in which the lipstick has been most lowered, the releasing protrusion (21) is in the lower lateral groove (26) and the rotating protrusion is in the lower horizontal groove (27). Next, when the lipstick is fed, the rotation protrusion is pulled up by the spiral groove and moves upward together with the inner plate holding the lipstick. The release projection and the rotation projection are respectively the vertical grooves (25) (24) of the tubular member.
Ascending upwards through a) and engaging the upper transverse grooves (28) (29) with further rotation. At this time, since the release projection lateral groove (28) is shorter than the rotation projection lateral groove (29), the releasing projection (21) exceeds the releasing lateral groove (28) when the maximum feeding position is exceeded. Is pushed by the inner wall of the tubular member, the assembly portion (23) bends inward, and the engagement between the assembly claw (15) and the assembly reverse claw (25a) on the main member side is released. When such a container is used, the contents can be easily taken out, so that even if a defective product occurs in the manufacturing process, the contents can be replaced, which is useful for effective use of resources. In addition, it is convenient because it is possible to replace a new product with the contents that have been used up.

Third Embodiment A third embodiment of the present invention will be described. In this embodiment, the vertical grooves (4a) of the first embodiment are not provided at symmetrical positions,
The number of release projections and the number of rotation projections are each one in correspondence with this. Further, as shown in FIG. 8 (b), the releasing projection has a gentle protrusion so that it can be released with a weak force. With such a configuration, the sense of stability in the rotating operation is slightly reduced, but the contents can be delivered or replaced without any problem. With such a simple structure, the strength of the tubular member is firmly maintained,
It is possible to provide a simple replaceable container that does not easily break down.

As described above, according to the replaceable rod-shaped delivery container of the present invention, defective products generated during manufacturing can be replaced by extending a series of delivery operations. Therefore, replacement of defective products is possible. It has become possible to efficiently produce and use the contents and containers. Further, since the feeding and taking out of the contents are regulated by the method of the groove of the cylindrical member, the mechanism is simple and the number of parts is reduced.
Manufacturing costs can also be reduced. In addition, the contents can be replaced after use or during use, the container is no longer disposable, saving resources, and using the container you like to replace the contents. It will be possible.
