Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention raises and lowers a core chuck by relatively rotating a shaft cylinder which is screwed with a core chuck for holding a rod-shaped cosmetic such as an eyeliner, eyebrow, lip liner, and eye shadow. The present invention relates to a dispensing container, and more particularly, to a dispensing container with buffer means that does not transmit an impact from the outside of the container to the core chuck and the stick-shaped cosmetic.

[0002]

2. Description of the Related Art Conventionally, an eyeliner, an eyebrow,
Attach stick-shaped cosmetics such as lip liner and eyeshadow to the core chuck, and form the inner shape of the front cylinder into a non-circular shape.
There is a cosmetic dispensing container in which a core chuck is slidably inserted into the front cylinder and a shaft cylinder (a feeding mechanism) which is screwed with the core chuck is relatively rotated to raise and lower the core chuck. Since this cosmetic dispensing container can shorten the length of the cosmetic dispensing container, there is an advantage that the container can be miniaturized,
For this reason, there have conventionally been many types of cosmetic dispensing containers of this type.

However, in the conventional cosmetic dispensing container, since the core chuck and the dispensing mechanism for dispensing the core are directly engaged with each other, when a shocking external force is applied to the outside of the container by dropping the container or the like. However, there is a fear that the impact of the container is transmitted to the core chuck via the feeding mechanism, and the rod-shaped cosmetic is damaged.

Therefore, a technique has been devised for buffering an impact when an impact external force is applied to the container. For example, Japanese Unexamined Utility Model Publication No. Hei. It is a structure of absorbing. 7-016711
A spring or rubber is used for the buffer member of the publication.

[0005]

[Problems to be Solved by the Invention]
In the case where a spring or a rubber material is used as the buffer means as disclosed in Japanese Patent No. 6711, it is a separate component. Therefore, an engaging portion is provided on both the core chuck and the feeding mechanism, and a spring or a rubber material is attached to the engaging portion. This has led to an increase in cost due to the cost of parts and assembling time.

Further, although the components constituting the feeding container are almost made of synthetic resin, if only the buffer means is made of a different material, the components cannot be integrally formed, which is an obstacle in reducing the number of components. .

In view of the above, the present invention has been made in view of the above-mentioned problems.
It is a technical object of the present invention to provide a dispensing container with a buffering means that can be integrally molded with other components to reduce the number of components and reduce assembly costs.

[0008]

The present invention adopts the following means in order to solve the above-mentioned problems. That is, the dispensing container with buffer means of the present invention comprises a core chuck having a rod-shaped cosmetic material attached thereto, a front cylinder in which the core chuck is non-rotatably and axially slidably inserted into the interior of the cylinder, and rotatably mounted on the front cylinder. A shaft cylinder to be engaged, a feeding mechanism provided in the shaft cylinder and screwed with the core chuck, and a container cover portion for housing the core chuck, the front cylinder, the shaft cylinder, and the feeding mechanism. In the feeding container for raising and lowering the core chuck in the front cylinder through the feeding mechanism by the relative rotation of the front cylinder and the shaft cylinder, molded into a cylindrical shape with synthetic resin,
Having an engaging portion that engages with the container cover portion, having a notch hole cut out in a shape combining a plurality of circumferential slits on the outer periphery, a middle tool stored in the container cover portion. The impact applied to the container cover portion is buffered by the notch hole of the inner member and is not transmitted to the core chuck and the stick-shaped cosmetic.

According to this configuration, even if an impact applied to the container cover is transmitted to the inside of the container via the engaging portion, the impact is added to the flexibility of the synthetic resin inner tool itself. It is buffered by the notch hole provided in the tool and is not transmitted to the core chuck and the bar-shaped cosmetic. As a result, the buffering means can be integrally formed with other synthetic resin parts such as a jig, and it is not necessary to use separate materials and parts as in the related art.

[0010] The dispensing container with shock absorbing means of the present invention may further comprise a notch hole formed by extending a tip of the barrel to the barrel, and combining a plurality of circumferential slits on the extended outer periphery. A configuration in which the notch hole is not provided on the inner side can also be exemplified, and the buffer means can be integrally formed with the shaft cylinder, and the number of parts can be reduced.

Further, there can be exemplified a component having a shape in which an outer peripheral end having a cutout hole of the center member and a tip of the shaft tube are joined together, and the center member and the shaft tube are integrally formed. The score can be further reduced.

With the above configuration, the number of parts is reduced, so that the assembly cost can be reduced. In addition, examples of the rod-shaped cosmetic to be attached to the core chuck include an eyeliner, an eyebrow, a lip liner, and an eye shadow. Also,
The feeding mechanism which is screwed with the core chuck and the shaft cylinder may be of a single structure or a double structure.

[Procedure for Assembling the Feeding Mechanism] Next, the procedure for installing the feeding mechanism including the shaft 9, the intermediate barrel 6, and the barrel 4 will be described.

In order to incorporate the lead chuck 2 into the intermediate barrel 6, the shaft 9 of the lead chuck 2 is inserted through the intermediate barrel 6, as shown in FIGS. That is, the shaft portion 9 is moved closer to the intermediate barrel 6 (see FIG. 13). Then the second protrusion 1
0 from the open end 8a of the second spiral groove 8, and the shaft 9
The screw fitting is performed while relatively rotating the and the intermediate barrel 6 (see FIG. 14). When the relative rotation between the shaft portion 9 and the intermediate shaft cylinder 6 is continued, the thread protrusion 24 abuts on the slope 35 of the protrusion 27. From this state, when the screw fitting by the relative rotation is further measured, the protrusion 27 climbs over the thread protrusion 24 from the slope 35, and as shown in FIG. 15, the protrusion 27 becomes the crest 23 of the second spiral groove 8. It is built in a state almost in contact with

Next, the first projection 7 of the intermediate barrel 6 is connected to the barrel 4

Is relatively rotated in the direction in which is stored, the second spiral groove 8 also rotates. The second protrusion 10 is provided in the second spiral groove 8 of the intermediate barrel 6.
, By rotation of the second spiral groove 8,
The core chuck 2 moves to the right, and the shaft portion 9 of the core chuck 2 is accommodated in the intermediate barrel 6. Further, if the relative rotation is continued, the rotation of the intermediate barrel 6 stops, and the first projection 7 provided on the outer peripheral surface of the intermediate barrel 6 is engaged with the first spiral groove 5. The intermediate barrel 6 moves inside the barrel 4 together with the core chuck 2.

Further, in order to extend the core chuck 2, the cap 32 is removed, and then the shaft cylinder 4 is rotated.
Spiral groove 5 rotates. Since the intermediate shaft cylinder 6 is engaged with the first spiral groove 5, the intermediate shaft cylinder 6 is guided by the polygonal elongated hole 11 of the front cylinder 1 together with the shaft portion 9 of the core chuck 2, and does not come off the elongated hole 11. It rises in a sliding state in the longitudinal direction. Large diameter part 25
Comes into contact with the lower end surface 28 of the front cylinder 1, the lifting of the intermediate barrel 6 stops. Then, the intermediate shaft cylinder 6 starts rotating, and the lead chuck 2 is raised in the polygonal long hole 11 of the front cylinder 1. Then, when the maximum feeding state is reached, the lifting of the core chuck 2 stops.

Further, the protrusion 27 has an engaging side surface 29 facing the cosmetic holding portion 14 formed along a surface orthogonal to the axis of the shaft portion 9 of the core chuck 2. When the inner side surface 30 of the thread projection 24 is formed along a plane perpendicular to the axis of the intermediate barrel 6, the engagement side surface 29 and the inner side surface 30 are in close contact with each other when the core chuck 2 is fully extended. , And the core chuck 2 is stably held without rattling. Then, the core chuck 2 is securely prevented from falling off.

Since the outer diameter Ds of the projection 27 is larger than the inner diameter Da of the small-diameter thread projection 24 at the open end 8a of the intermediate barrel 6, the projection of the core chuck 2 at the maximum feeding of the core chuck 2 is performed. Since the engaging side surface 29 of the portion 27 abuts on the inner side surface 30 of the small-diameter thread projection and stops, there is no possibility that the core chuck 2 will fall off.

The engagement side surface 29 of the projection 27 and the thread projection 24
And the engagement side surface 29 of the projection 27 is in close contact with the inside side surface 30 of the thread projection 24 at the maximum extension of the core chuck 2.
The core chuck 2 does not fall off.

[Operation of the buffer means of the present invention] When the cosmetic dispensing container with the buffer means is dropped on a floor or the like, an impact external force is applied to the container cover portion B, and further the impact external force is applied to the container cover portion B.
Is transmitted to the middle tool 40 through the annular convex portion 41 engaging with the inner tool 40. However, the inner member 40 is not limited to the flexibility of the synthetic resin itself and the notch hole 44.
The shock-absorbing function is provided in the axial direction and the rotational direction by the resilience provided by the above, so that no shocking external force is transmitted to the container body A. That is, the shock-absorbing function of the inner member 40 does not transmit an impacting external force to the adjacent barrel 4 and does not transmit an impacting external force to the core chuck 2 connected to the barrel 4 via the feeding mechanism. There is no risk of damage.

Further, according to this embodiment, the material of the buffer means is made of the same synthetic resin as the other parts and can be integrally formed with the parts constituting the container, so that the number of parts can be reduced and the assembly cost can be reduced. Can be reduced.

[Another Embodiment] In the above-described embodiment (Embodiment 1), the notch 44 is provided on the side of the middle member 40 adjacent to the shaft cylinder 4 to provide the buffer means. As an embodiment (Embodiment 2), as shown in FIG. 16, a buffer means (a notch hole) may be provided on the shaft cylinder 4a side and no buffer means may be provided on the inner tool 40a side. That is, FIG.
As shown in FIG. 7, the distal end of the shaft cylinder 4a is extended in a tubular shape, and a cutout hole 44 combining a plurality of circumferential slits 44a, 44b is formed on the extended outer periphery. In the second embodiment, the feeding mechanism which is screwed with the core chuck 2a and the shaft cylinder 4a has a single structure. That is, the core chuck 2a is a combination of the core chuck 2 of the first embodiment and the intermediate shaft cylinder 6, and the projection 7a of the core chuck 2a is
Of the first spiral groove 5.

The difference between the first embodiment and the second embodiment is that the lead chuck is combined with the intermediate barrel to form a single-layer feeding mechanism, and that the shapes of the barrel and the inner member are changed. Only the differences are described, and the other components are the same as those in the first embodiment, so that the description thereof will be omitted.

According to the second embodiment, even if the impact external force due to the container falling is transmitted to the middle member 40a, the middle member 4
Since the notch 44 is provided at the tip of the barrel 4a adjacent to the cylinder 0a, the elasticity of the barrel serves as a buffering function in the axial and rotational directions. I don't get it.

In another embodiment (Embodiment 3), the inner member and the shaft cylinder may be integrally formed. That is, as shown in FIG. 18, the other end of the middle member 40 of the first embodiment and the distal end of the shaft cylinder 4 are integrally formed into a shape 4b. The difference between the first embodiment and the second embodiment is only the difference between whether the barrel and the inner member are separate parts or integral parts. Since the other parts are the same as those in the first embodiment, the description thereof will be omitted. Is omitted.

According to the third embodiment, even if an impact external force due to the falling of the container is transmitted to the inner tool 40 side, the elasticity of the notch holes 44 provided on the inner tool 40 side and the shaft cylinder 4 side causes the elasticity. Since the cushioning function is performed in the axial direction and the rotation direction, no shocking external force is transmitted to the barrel 4 even in the same part. According to the third embodiment, the number of parts can be further reduced, and the assembly cost can be further reduced.

[0045]

As described above, according to the present invention, even if an impact applied to the container cover is transmitted to the inside of the container via the engaging portion,
In addition to the flexibility of the synthetic resin inner tool itself, this impact is buffered by a notch provided in the inner tool, and is not transmitted to the core chuck and the rod-shaped cosmetic. As a result, the buffering means can be integrally formed with other synthetic resin parts such as the jigs, so that it is not necessary to use separate materials and parts as in the related art, and the number of parts can be reduced. Therefore, the present invention can also reduce the assembly cost.
