Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling-type stick-shaped cosmetic container for filling and containing a stick-shaped cosmetic such as lipstick in a molten state, and in particular, a straight tube having a relatively small diameter is used for the main body. It is related to the airtight mechanism.

[0002]

2. Description of the Related Art A conventional filling-type stick-shaped cosmetic material container has a structure as shown in FIG. That is, a so-called step drawing tube in which a flat plate is drawn into a cylindrical body has a drawback that the number of steps is large. For this reason, in order to reduce the number of steps, improve the dimensional accuracy, improve the dimensional stability, and improve the feeling of feeding and feeding, it is conceivable to use a straight tube that has been subjected to a drawing process for the main body 101.

That is, in a conventional container, there is first a hakama cylinder 100, and a main body 101 is coaxially arranged on the inner peripheral side of the hakama cylinder 100 with a gap. A filling 103 was attached between the central portion of the main body 101 and the hakama cylinder 100. An outer cylinder 10 having a spiral groove 107 spirally provided on the inner peripheral surface between the hakama cylinder 100 and the main body 101.
5 was placed. The inner plate body 1 is provided on the inner peripheral side of the main body 101.
09 was arranged. The inner plate body 109 is configured such that the projections 111, 111 provided on the lower end portion are screwed into the spiral groove 107 through the sliding holes 113, 113 provided on the lower portion of the main body 101. The stick-shaped cosmetic material is stored and held in the inner plate body 109, and the hakama barrel body 100 is rotated so as to be drawn out and put in. in this case,
The outer cylindrical body 105 was fitted to the main body 101, and the inner tool 103 was fitted to the outer cylindrical body 105 and the main body 101, respectively. Therefore, there are the following drawbacks.

[0004]

That is, when the diameter of the filling 103 is reduced to increase the airtightness of the container, the filling 103 is reduced.
The resistances between the main body 101 and the outer cylinder body 105 are too large. For this reason, there is a drawback that feeding and feeding becomes heavy.

If the diameter of the filling 103 is too large,
The resistances between the filling 103 and the main body 101 and the outer cylindrical body 105 are too small, respectively. For this reason, there is a disadvantage that feeding and feeding becomes light.

[0006] As described above, it is often difficult to achieve both airtightness and feeding / feeding in. Therefore, conventionally, it has been generally considered that airtightness in a straight tube is difficult. In particular, a small-diameter straight tube was even more difficult to fill with cosmetics.

Further, the conventional container has a drawback in that the accuracy of the diameter of each cylindrical body must be made accurate, and it has not been possible to effectively deal with variations in product accuracy.

By the way, recently, for example, stick-shaped cosmetics such as lipsticks that are hard to remove or moist are popular. However, in terms of ingredients, such cosmetics are
It is characterized by relatively large amounts of volatile substances. For this reason, unless the airtightness of the container is improved, the usability of the cosmetic may be deteriorated due to aging. If the container does not have good airtightness, the cosmetic material contracts after filling, resulting in "detachment", (a phenomenon in which the sticky material comes out of the inner dish as a result of contraction), and "gets up" (the sticky material There were many occurrences such as "a phenomenon that cannot effectively cope with feeding and feeding") and "folding" (a phenomenon in which the stick-shaped cosmetic material is easily broken or broken as a result of contraction).

The present invention has been made in view of such a background. That is, an object of the present invention is to improve the airtightness of a filling type rod-shaped cosmetic container using a straight tube as a main body, and to improve the feeding and feeding of the cosmetic container and to improve the stability. As a result, even in the case of cosmetics containing a large amount of volatile components, good usability is maintained for a relatively long period of time, and the occurrence of "drop", "left behind", and "break" is prevented.

Another object of the present invention is to effectively deal with variations in the product accuracy of the main body, the outer cylinder, the inner body, and the like.

The upper part of the filling is pressed against the inner peripheral surface of the inner cap. As a result, the airtightness of the entire container becomes great.

On the other hand, when the container is fed out and fed in, the external pressure acts in the opposite direction with the rib as the fulcrum, so that there is no change in the frictional resistance between the filling and the main body and the outer cylinder. Therefore, it is possible to perform feeding and feeding according to the set optimum resistance.

The above-mentioned fitting relationship is not affected even if the accuracy of the diameter of each cylinder such as the outer cylinder, the inner component, and the main body varies to some extent.

The outer cylinder body 9 is fitted into the hakama cylinder body 1 by force fitting. A spiral groove 11 is spirally formed on the inner peripheral surface of the outer tubular body 9. An annular groove 5b is provided above the spiral groove 11 and on the inner peripheral surface of the outer cylindrical body 9 corresponding to the projecting arcuate curved portion 5a, and the fitting portion 5 is formed between the annular groove 5b and the main body 3. doing.

On the inner peripheral side of the main body 3, there is disposed an inner plate body 13 which is a cylindrical body which is open vertically. A pair of protrusions 15 and 15 are provided at symmetrical positions at the lower end of the inner plate body 13, and the pair of protrusions 15 and 15 form the sliding hole 4 described above.
It is adapted to be threadedly engaged with the spiral groove 11 through. The stick-shaped cosmetic material 37 is accommodated and held in the inner plate body 13.

The fitting relationship between the main body 3, the inner member 7 and the outer cylindrical body 9 will be described in more detail with reference to FIG. The upper portion 17 of the outer tubular body 9 is formed from the upper end to just above the fitting portion 5, the inner diameter a is larger than the inner diameter c of the tubular body, and the outer diameter b is smaller than the outer diameter d of the tubular body. Has been formed. Such an upper part 17
A gap G is formed between the main body 3 and the filling 7. A linear rib 19 is provided on the inner peripheral surface of the upper portion 17 along the circumferential direction, and the rib 19 is in sliding contact with the outer peripheral surface of the main body 3.
A projecting portion 21 is projectingly provided on the inner peripheral surface of the filling 7 positioned above the rib 19 and slidably contacts the outer peripheral surface of the outer cylindrical body 9. On the other hand, the lower end 23 of the upper portion 17 located below the rib 19 is in sliding contact with the inner peripheral surface of the filling 7 whose lower end portion 25 extends straight.

The upper portion of the inner component 7 is detachably fitted between the inner cap 29 fixed to the cap 27 and the main body 3 so as to be detachable. That is, the protrusion 31 that is curved in an annular shape is provided on the outer peripheral surface of the upper portion of the inner component 7, and the protrusion 31 is fitted into the corresponding recess 33 of the inner cap 29 to form the fitting portion 35. Inner cap 29
The lower end portion 30 of the is expanded so that the filling 7 can be easily attached and detached.

In order to fill the cosmetic material 37 into the filling type stick-shaped cosmetic material container having the above-mentioned structure, the molding tool (not shown) is capped on the upper end of the main body 3 with the cap 27 removed, and melted from the hole 2. Fill the state of cosmetics. After filling, a seal is attached to the hole 2 on the bottom surface of the hakama cylinder 1. After the cosmetic is solidified, the molding die is removed and the cap 27 is fitted.

The hakama cylinder 1, the main body 3 and the cap 27
Is preferably made of a metal such as aluminum, and the filling 7 is preferably made of a metal such as brass.
The outer cylinder 9 is preferably made of polyacetal, the inner plate 13 is preferably made of polybutylene phthalate, and the inner cap 29 is preferably made of a thermoplastic resin such as ultra-low density polyethylene.

Reference numeral 39 in the figure denotes an outer protrusion provided at the center of the inner tool 7.

The operation and effect of the above structure will be described with reference to FIG. First, the inner tool 7, the main body 3, and the outer cylindrical body 9
When the external pressure is applied, the fitting relationship between and becomes as shown in A to B of FIG. That is, when the hakama cylinder 1 is strongly fitted to the inner tool 7 and the tightening of the inner tool 7 is strengthened, the protrusion 21 of the inner tool 7 presses the outer peripheral surface of the upper portion 17 of the outer tube 9 with the rib 19 as a fulcrum. To do. On the other hand, in the direction opposite to this pressing, the upper lower end 23 of the outer tubular body 9 presses the inner peripheral surface of the lower end portion 26 of the filling 7.
In this way, the upper portion 17 of the outer cylindrical body 9 made of resin is provided with the rib 19
Acts like a spring with the fulcrum as the fulcrum. Further, since the protrusion 31 provided on the upper portion of the inner component 7 is pressed against the recess 33 side of the inner cap 29, the close contact of the fitting portion 35 is further enhanced. As a result, the airtightness of the entire container is further increased.

As described above, since the force of the external pressure acts in the opposite directions with the rib 19 as a fulcrum, the resistance force between the inner tool 7 and the main body 3 and the outer cylindrical body 9 does not increase. Therefore, the feeding and feeding of the container can be performed under the optimum set conditions.

Therefore, in the filling-type stick-shaped cosmetic container using a straight tube having a relatively small diameter in the main body, the airtightness can be improved, and the feeding and feeding can be improved and the stability can be improved. Both are compatible. As a result, even in the case of cosmetics containing a large amount of volatile components, the degree of change over time is small, so that the state of good usability lasts for a relatively long period of time, and there are no "drops", "leaves", and "breaks". It is possible to prevent the occurrence.

Further, the above-mentioned fitting relations are as follows:
Even if the accuracy of the diameter of each cylinder such as the main body varies, it is not affected.

The filling type rod-shaped cosmetic material container according to the present invention is not limited to the above-mentioned embodiments. For example, rib 1
9 may be provided in a line shape or may be provided in a dot shape.

As shown in FIG. 3, the upper portion 18 of the outer tubular body 9 in the fitting relationship between the main body 3, the inner component 7 and the outer tubular body 9 is as follows.
It may be formed from the upper end to just below the fitting portion 5 with the main body 3.

Further, the lower end portion 26 of the filling 7 located at the lower end of the upper portion 17 may be bent and formed as shown in FIG.

Further, when fitting the inner tool 7 and the outer tube body 9, instead of the projection 21 of the inner tool 7, the upper end 10 of the outer tube body 9 is opened to the inner tool 7 side, and the inner tool 7 is opened. Even if it makes sliding contact with the inner peripheral surface (FIG. 5), it has the same operation and effect as in the first embodiment as shown in FIG.

Similarly, in place of the protrusion 21 of the filling 7, a protrusion 22 is provided along the circumferential direction on the outer peripheral surface of the upper end portion of the outer tubular body 9 and slidably contacts the inner peripheral surface of the filling 7. (Fig. 6),
As shown in FIG. 9B, there are the same actions and effects as those of the first embodiment. The protrusion 22 may be provided in a dot shape or a linear shape.

As shown in FIGS. 3 to 7 described above, when the lower end portion 26 of the inner tool 7 located at the lower end of the upper portion 17 is bent and slidably fitted on the outer peripheral surface of the outer cylinder body 9, Ingredient 7
Since the fitting relationship with the outer cylindrical body 9 is further strengthened, the strength with which the main body 3 is pulled out from the container is further improved.

When fitting the inner tool 7 and the inner cap 29, a projection may be provided on the inner peripheral surface side of the inner cap 29, and a corresponding concave section may be provided on the upper outer peripheral surface of the inner tool 7. However, the fitting example of the inner tool 7 and the inner cap 29 is better in the illustrated example of FIG.

Furthermore, the various modifications described above can be combined as appropriate.

Further, as the metal or the resin which constitutes each member, appropriate ones other than those described in the above embodiments can be used.

The shape and form of the inner plate body are arbitrary. For example, the outer shape is elliptical in cross section (FIG. 8), and ribs 13a, 13a are provided at symmetrical positions on the outer circumferential surface in the longitudinal direction from the upper end to the lower end.
May be provided (FIG. 9), or ribs 13b, 13b may be provided so as to project from the vicinity of the protrusion 15 to the lower end at symmetrical positions on the outer circumferential surface in the longitudinal direction (FIG. 10). 9 and 10, A is a partially cutaway vertical sectional view, and B is a lateral sectional view.

Next, as the main body 3, a so-called step-type throttle tube, which is a conventional type and is formed by narrowing a flat plate, may be used. However, it is desirable to construct the main body 3 from a straight tube that has been drawn as in the illustrated example. This is because the whole container can be made slender, the processing stability is great because there is no need for cutting work, and the protrusion of the inner plate body is pulled to the part where the middle plate body is narrowed when inserting it into the main body. There is no danger of being damaged by hanging, and because overrun torque is large, it is difficult to overrun, etc.
This is because the feeding is further improved. Therefore, the effect of the present invention is remarkably exhibited especially when the straight tube is used for the main body 3.

[0039]

As described above, according to the filling type stick-shaped cosmetic container according to the present invention, it is possible to improve the airtightness, to improve the feeding and feeding, and to stabilize the both. There is an effect. As a result, even in the case of cosmetics containing a large amount of volatile components, a good usability state can be maintained for a relatively long period of time, and it is possible to prevent the occurrence of "drop", "left behind", and "fold". . Further, the above-mentioned fitting relationship has an effect that it is not affected even if the diameter accuracy of each tubular body such as the outer tubular body, the inner tool, and the main body varies to some extent.
