DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic container in which a straight tube is used as a main body for accommodating a cosmetic, and more particularly to improving the feeding and feeding of the container.

[0002]

2. Description of the Related Art There is a drawback that a so-called throttle tube which is formed by narrowing a flat plate into a cylinder has a large number of steps. If the number of steps is large, it is very difficult to make the cylinder a perfect circle. For this reason, in order to reduce the number of processes, thereby improving dimensional accuracy, dimensional stability, and feeding and feeding performance, the main body 101 is used.
It is conceivable to use a drawn straight pipe. Conventional cosmetic container using a straight tube to the body, has been a structure as shown in FIG. 22 for example.

[0003] That is, first, there is a hakama cylindrical body 100, and a main body 101 is coaxially arranged on the inner peripheral side of the hakama cylindrical body 100 with a space therebetween. An intermediate piece 103 was attached between the center of the main body 101 and the skirt body 100.
An outer cylinder 105 having a spiral groove 107 spirally formed on the inner peripheral surface is arranged between the hakama cylinder 100 and the main body 101. An inner plate body 109 was disposed on the inner peripheral side of the main body 101. The inner plate body 109 is provided with a projection 11 provided at a lower end portion.
1 and 111 are sliding holes 11 provided in the lower part of the main body 101.
3, 113, and screwed into the spiral groove 107. 115 is a sliding part. Such an inner plate body 109
The cosmetic material is stored and held in the container, and the hammer cylinder body 100 is rotated to be fed and fed. In this case, the outer cylinder 105 was fitted to the main body 101, and the middle tool 103 was fitted to the outer cylinder 105 and the main body 101, respectively. For this reason, when the dimensions of the cylinder diameter of the main body, the outer cylindrical body, and the jig vary (these variations occur frequently), there are the following defects.

[0004]

That is, if the diameter of the middle member 103 is smaller than an appropriate size, the sliding resistance between the main body 101 and the outer cylinder 105 in the sliding portion 115 becomes too large. For this reason, there was a drawback that the feeding and the feeding became heavy and could not be carried out smoothly.

If the diameter of the inner member 103 is larger than an appropriate size, the main body 101 and the outer cylinder
5 are too small. For this reason,
There were drawbacks such as rattling during feeding and feeding, and too little feeding and feeding, resulting in a poor feeding feeling.

In the case where the straight pipe is used for the main body as described above, if the dimensional accuracy of the main body, the outer cylindrical body, the middle member and the like is not made accurate, it is possible to obtain a smooth feeding and feeding and a good feeling of feeding. There was a disadvantage that it could not be done. Therefore, when a straight pipe is used for the conventional body, some backlash is inevitable, and it is generally considered that it is generally difficult to maintain airtightness in a container using the body made of a straight pipe. Was. By the way, conventionally, by injecting silicone oil or the like, it was attempted to prevent rattling and to improve feeding and feeding. But,
Silicone oil and the ingredients of cosmetics are chemically incompatible, and the use of silicone oil has not been desirable.

[0007] For example, cosmetics such as lipstick, which are difficult to remove and those which have moisture, have recently become popular. However, such cosmetics are characterized by relatively large amounts of volatile substances when viewed in terms of components. For this reason,
If the airtightness of the container is not improved, there is a possibility that the usability of the cosmetic may be deteriorated due to a change over time. If the container is not airtight, the cosmetic will shrink after storage,
(Phenomenon that the cosmetic comes out of the inner plate as a result of shrinkage),
There were many occurrences of "getting up and down" (a phenomenon in which the cosmetics could not effectively cope with feeding and unloading) and "breaking" (a phenomenon in which the cosmetics were easily broken or broken as a result of shrinkage).

[0008] The present invention has been made in view of such a background. That is, an object of the present invention is to achieve good feeding and feeding. Another object of the present invention is to improve the airtightness of a cosmetic container using a straight tube as a main body. As a result, even when used as a cosmetic container having a large amount of volatile components, the good usability is maintained for a relatively long period of time, and the occurrence of “falling out”, “leaving away” and “breaking” is prevented. is there.

[0009]

In order to achieve the above-mentioned object, the present invention provides a main body comprising a vertically open straight cylindrical body having a sliding hole formed in a lower part along a longitudinal direction, and a vertically open cylindrical body. A rotatable outer cylinder body having the inside slidingly fitted with the main body and having a spiral groove on the inner peripheral surface; and a cylindrical body formed at the lower end through the sliding hole so as to be slidable in the spiral groove. In a cosmetic container comprising: an inner plate body having projections to be engaged and accommodating / holding the cosmetic; and an inner tool attached to the outside of the main body, an action portion is provided on an upper portion of the outer cylindrical body. A gap is formed between the tool in which the action portion is disposed and the main body, and a rib is provided on the inner peripheral surface of the action portion along the circumferential direction. Characterized in that both ends of the action portion are elastically contacted with the middle member with the rib being interposed therebetween. Subjected to. At this time, it is conceivable that the working portion is formed to have a large inner diameter and a small outer diameter.
Further, it is conceivable to provide a protrusion on the inner peripheral surface of the middle tool located above the rib. In addition, it is conceivable that the upper end of the action section is expanded toward the jig. In addition, it is conceivable to project a projection along the circumferential direction on the outer peripheral surface of the upper end of the action portion. Further, it is conceivable to provide the ribs in a dot shape. It is also conceivable to provide the ribs endlessly. Further, it is conceivable to provide the protrusions in a point-like manner.
In addition, it is conceivable to provide the above-mentioned protrusions endlessly. Also, the above-mentioned action portion is a portion where the outer cylinder body is slidably fitted to the main body.
It is conceivable that it is formed with a portion from just above the minute to the upper end . In this case, it is conceivable that the middle part located at the lower end of the action part is straight. In this case, it is conceivable that the middle part located at the lower end of the action part is bent toward the outer cylinder. In addition, the above-mentioned action portion is an outer cylindrical body
Can be considered to be formed with a portion from immediately below to a top end of a portion that is slidably fitted to the main body . in this case,
It is conceivable that the middle part located at the lower end of the action part is straight. In this case, it is conceivable that the middle part located at the lower end of the action part is bent toward the outer cylinder . Further, a combination of all or some of these is also conceivable.

[0010]

[Action] An outer cylinder when external pressure is applied, that is, when the forcible fitting between the hakama cylinder and the middle tool is strengthened, and the tightening between the middle tool, the main body, and the outer cylinder is strengthened. The fitting relation between the middle tool and the main body is as follows.

That is, with the rib as a fulcrum, the projecting portion of the middle tool acts as a point of force and presses one end of the action portion formed on the upper portion of the outer cylinder, while the other end of the action portion moves in the opposite direction to the pressing. It becomes an action point and presses the inner peripheral surface of the jig. As a result, the airtightness between the inner member, the main body, and the outer cylinder is increased.

On the other hand, when the container is extended and retracted, the external pressure acts in opposite directions with the rib as a fulcrum, so that the force for tightly fitting the components of the container is completed at the action portion. Therefore, there is no change in the frictional resistance between the main body and the outer cylinder in the sliding portion. Therefore, according to the set optimal resistance, that is, an appropriate weight (frictional force)
Can be carried out and taken in with.

Further, even if the accuracy of the diameters of the respective cylindrical bodies such as the outer cylindrical body, the inner tool and the main body slightly varies, they are absorbed by the gap formed at the action portion, so that the extending / removing and airtightness can be improved. Has no effect.

Between the central portion of the main body 3 and the skirt cylinder 1, a middle member 7 composed of a vertically open cylinder is attached. An outer cylinder 9 composed of a vertically open cylinder is disposed between the hakama cylinder 1 and the main body 3. The outer cylinder 9 is fitted to the hakama cylinder 1 via the middle member 7 by forced fitting. A spiral groove 11 is spirally formed on the inner peripheral surface of the outer cylinder 9. An annular groove 5b is provided on the inner peripheral surface of the outer cylindrical body 9 above the spiral groove 11 and corresponding to the arc-shaped curved portion 5a, and forms the sliding portion 5 with the main body 3. doing.

An inner plate 13 is disposed on the inner peripheral side of the main body 3. The upper portion of the middle plate 13 is a plate portion 14, and the lower end is provided with a pair of protrusions 15 at a symmetrical position. And screwed into the spiral groove 11. The cosmetic 37 is accommodated and held in the dish portion 14 of the intermediate dish 13. 14a is a ridge provided on the plate portion 14 in the vertical direction, and 14b is a small hole provided on the bottom.

Referring to FIG. 2, the fitting relationship between the main body 3, the middle member 7, and the outer cylinder 9 will be described in more detail. The upper portion of the outer cylindrical body 9 is formed as an action portion 17 with a portion from the upper end to just above the sliding portion 5. The action portion 17 has an inner diameter a
Is larger than the inner diameter c of the outer cylinder 9 and the outer diameter b is
Is formed smaller than the outer diameter d. Such action part 17
, A gap G is formed between the main body 3 and the middle tool 7. A point-like rib 19 is provided on the inner peripheral surface of the action portion 17 along the circumferential direction, and the rib 19 comes into sliding contact with the outer peripheral surface of the main body 3. A projecting portion 21 is provided on the inner peripheral surface of the jig 7 located above the rib 19, and the projecting portion 21 is
Abuts the outer peripheral surface of. On the other hand, the lower end portion 23 of the action portion 17 located below the rib 19 abuts on the inner peripheral surface of the middle member 7 whose lower portion 25 is extended straight. In addition, as shown in FIG. 1A, a slit 24 is appropriately provided on the upper portion of the outer cylinder 9 for assembling and fitting with the main body 3.

The upper part of the middle tool 7 is detachably fitted between the inner cap 29 fixed to the cap 27 and the main body 3 so as to be airtight. That is, a protrusion 31 which is bent in an annular shape is provided on the upper outer peripheral surface of the middle tool 7, and is fitted to the corresponding concave portion 33 of the inner cap 29 to form a fitting portion 35. Inner cap 29
The lower end portion 30 is expanded so that the attachment 7 can be easily attached and detached.

The cosmetic 37 is accommodated in the cosmetic container having the above structure by inserting the solidified bar-shaped cosmetic 37 from above.

In the figure, reference numeral 39 denotes an outer projection provided at the center of the jig 7.

In the case of the above embodiment, each of the constituent members is made of a metal body such as aluminum, and the inner shell 7 is made of a metal such as brass. Have been. The outer cylinder 9 is made of, for example, polyacetal (POM), the inner plate 13 is made of, for example, polypropylene (PP), and the inner cap 29 is made of, for example, a thermoplastic resin such as linear low-density polyethylene.

The operation and effect based on the above configuration will be described with reference to FIG. First, the jig 7, the main body 3, and the outer cylinder 9
7A to B in FIG. 7 when external pressure is applied. That is, when the hammer cylinder 1 is forcibly fitted to the middle tool 7 and the tightening of the middle tool 7 is increased, the projection 21 of the middle tool 7 becomes a point of force with the rib 19 as a fulcrum, and the action portion 1 of the outer cylinder 9
7 is pressed. On the other hand, in the direction opposite to the pressing, the lower end 23 of the action portion becomes the action point,
The point 26a on the inner peripheral surface of No. 6 is pressed. Thus, the action portion 17 of the outer cylinder 9 made of resin acts like a spring with the rib 19 as a fulcrum. For this reason, the airtightness between the main body 3, the middle tool 7, and the outer cylindrical body 9 is large.

However, since the force for tightly fitting the components of the container acts in the opposite directions with the rib 19 as a fulcrum and is completed at the action portion, the main body 3 and the outer cylinder in the sliding portion 5 are completed. The sliding resistance force with the body 9 does not increase. Therefore, the feeding and unloading of the container can be performed under the set optimum conditions.

Further, an inner cap 29 is provided in the cap 27, and since the protrusion 31 is pressed toward the recess 33 of the inner cap 29 at the upper portion of the middle tool 7, the degree of adhesion of the fitting portion 35 is further strengthened. Is done. As a result, the airtightness of the entire container is further enhanced.

As described above, according to this embodiment, the feeding and
Good transfer can be achieved. In addition, since the airtightness can be improved, even when used as a cosmetic container having a large amount of volatile components, a good usability state is maintained for a relatively long time, and "extraction" and "leave" , "Break" can be prevented.

In addition, even if the accuracy of the diameter of each cylindrical body such as the outer cylindrical body, the inner tool, and the main body varies to some extent, it is absorbed by the gap formed at the action portion, so that it can be fed out / retracted and airtight. Does not affect

The cosmetic container according to the present invention is not limited to the embodiment described above. For example, the ribs 19 may be provided endlessly or may be provided dotwise.

As shown in FIG. 3, in the fitting relationship between the main body 3, the middle member 7, and the outer cylindrical body 9, the action portion 18 of the outer cylindrical body 9 is located directly below the sliding portion 5 with the main body 3 from the upper end as shown in FIG. It may be formed with parts up to.

The lower part 26 of the middle tool 7 located at the lower end of the action part 17 may be formed by bending as shown in FIG.

In fitting the inner member 7 and the outer cylindrical body 9, the upper end 1 of the working portion 17 is replaced with the protrusion 21 of the inner member 7.
Even if the “0” is expanded toward the inner tool 7 and abuts against the inner peripheral surface of the inner tool 7 (FIG. 5), the same operation and effect as in the first embodiment are obtained as shown in FIG.

Similarly, instead of the protrusion 21 of the middle tool 7, a protrusion 22 is provided along the circumferential direction on the outer circumferential surface of the upper end portion of the working portion 17, and is brought into contact with the inner circumferential surface of the middle tool 7. (Fig. 6),
As shown in FIG. B, the same operations and effects as in the first embodiment are obtained. The protrusion 22 may be provided in a dot shape or in an endless shape.

As shown in FIGS. 3 to 7 described above, when the lower portion 26 of the middle member 7 located at the lower end of the action portion 17 is bent and fitted to the outer peripheral surface of the outer cylinder 9, Tool 7
Further, since the fitting relationship with the outer cylinder 9 is further strengthened, the strength of the main body 3 coming out of the container is further improved.

As shown in FIG. 7, it is desirable to form the ribs 19 in an arc shape because the spring effect is further improved.

The shape and form of the outer shape of the inner plate 13 are arbitrary. For example, when the outer shape is an elliptical cross section (FIG. 8), the ridge 13 extends from the upper end to the lower end at symmetrical positions on the outer peripheral surface in the longitudinal direction.

Next, the curved structure 5a of the sliding portion may be formed in the main body 3 by a so-called drawing process of drawing a flat plate into a cylindrical body as in the conventional type. However, it is desirable that the main body 3 be formed from a straight pipe that has been drawn as shown in the illustrated example. This is because there is no need to perform drawing, so the stability of processing is large, and when inserting the middle plate into the main body, there is no risk of catching the projection of the middle plate and damaging it at the drawn portion. It is because it is difficult to run, and the feeding and feeding are further improved. Therefore,
The effect of the present invention is remarkably exhibited especially when a straight tube is used for the main body 3.
