[0002]

2. Description of the Related Art A conventional stick-shaped cosmetic container is shown in FIG.
The structure is as shown in FIG. That is, first, the hakama barrel 10
0, and the main body 101 was coaxially arranged on the inner peripheral side of the hakama cylinder 100 with a gap. The body 10
A filling 103 was attached between the central portion of 1 and the hakama cylinder 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 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 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.
Therefore, there are the following drawbacks.

That is, if the number of parts is large as described above, it takes time to assemble and the cost is increased. Therefore, it becomes necessary to reduce the number of parts.

In order to reduce the number of parts, it is considered that the hakama barrel 100 and the inner tool 103 are integrated. However, in the conventional container, the hakama cylinder 100 and the outer cylinder 105 are separate bodies, and the wall thickness of the cylinder is thin, so that the welding area is small and it is difficult to weld. For this reason, even if the hakama 100 and the filling 103 are welded, the welding becomes imbalanced and the strength is not stable. If the filling 103 is not stable in strength, the main body 101 cannot be firmly held, and the main body 101 may eventually come out of the container.

For the above reasons, the stick-shaped cosmetic container for preventing the main body from coming off by reducing the number of cylinders as parts has not been successful.

The present invention has been made in view of such a background, and while reducing the number of cylinders as parts,
The purpose is to prevent the main body from coming off the container.

The operation and effect will be described based on the above configuration.

First, the outer cylinder 1 and the inner tool 7 are obtained by welding the lower end of the inner tool 7 to the upper end of the outer cylinder 1 having a thick peripheral wall. Therefore, since the welding area is large, the welding is easy and the connection between the outer cylinder 1 and the filling 7 is very strong. Since the fitting portion 5 of the main body 3 is sandwiched by the sandwiching portion 21 that is stable in strength, the strength with respect to the disengagement of the main body 3 is improved. As a result, the body 3 from the container
Is prevented from coming off.

Further, since the cylindrical body as a part is reduced, it can be easily assembled.

Further, the outer cylinder 1 and the filling 7 are integrally formed, and are slidably contacted to the main body 3 via ribs 9 projecting from the inner peripheral surface of the filling 7. That is, the outer cylinder body 1 and the inner tool 7
Is not fitted to the main body 3 by a solid body, so even if there is some variation in the diameter of the outer tubular body 1, the filling 7 or the tubular body of the main body 3, it is absorbed by the gap G existing between the two, and The frictional resistance of does not increase. Moreover, the rib 9 only contacts the inner peripheral surface of the main body 3 in a dot - like or endless manner. Therefore, the resistance between the outer cylinder body 1 and the inner tool 7 and the main body 3 is small and appropriate, so that the feeding and feeding is good.

The stick-shaped cosmetic container according to the present invention is not limited to the above embodiment. For example, the fitting structure between the inner tool 7 and the cap 23 is arbitrary. The cases shown in FIGS. 4 to 8 can be considered.

In FIG. 4, an annular protrusion 33 is provided on the outer peripheral surface of the upper part of the inner part 7 below the rib 9, while on the inner peripheral surface of the cap 23, the protrusion 33 is formed. This is a case where another protrusion 35 is provided adjacent to, and the protrusion 33 and the protrusion 35 are engaged with each other.

In FIG. 5, a groove 37 is provided along the longitudinal direction on the peripheral wall of the filling 7, and the peripheral wall of the filling 7 is made like a spring.
This is a case where the filling 7 is elastically contacted with the cap 23 when the cap 23 is fitted.

In FIG. 6, the inner cap 39 is mounted in the cap 23. In such a case, the projection 43 provided on the outer peripheral surface of the filling 7 is fitted into the concave portion 41 provided on the inner peripheral surface of the inner cap 39. To meet. The lower end portion 45 of the inner cap 39 is expanded to facilitate the attachment / detachment of the inner component 7. In this case, it is desirable that the recess 41 and the protrusion 43 be provided above the rib 9.

FIG. 7 shows the case of an airtight container which does not use an inner cap. In this case, an annular protrusion 47 is provided on the inner peripheral surface of the upper portion of the cap 23 and is brought into contact with the outer peripheral surface of the main body 3. In order to contribute to the airtightness, the filling 7 has a structure as shown in FIG.

FIG. 8 shows a case in which the inner cap 39 attached to the cap 23 is made airtight by abutting the upper end portion 49 of the main body 3, and the present invention can be applied to such a container.

In the case of FIG. 4, an airtight container can be formed depending on the size and material of the cap 23 and the filling 7.

As described above, the present invention can be applied to both airtight containers and non-airtight containers.

Further, as shown in FIG. 9, the inner component and the outer cylinder 1
It is also possible to integrally form and. Reference numeral 7a indicates a portion corresponding to a filling.

Further, the present invention can be applied to a container using an outer cylinder having no hole 2 on the bottom surface. Therefore,
INDUSTRIAL APPLICABILITY The present invention can be applied not only to a filling type container, but also to a type of container in which a cosmetic material is inserted into an inner dish to be stored and held.

Appropriate materials can be used for the material of each part. For example, for the outer cylinder 1, the inner component 7, and the cap 23, acrylonitrile-styrene resin (A
S) and polypropylene for the inner plate 13 (PP)
Can be used.

Next, the main body 3 may use a so-called step throttle tube which is a conventional type and is formed by narrowing a flat plate into a cylindrical body. 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 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 transfer is further improved. Therefore, the effect of the present invention is remarkably exhibited particularly when a straight tube is used for the main body 3.

The method of welding the holding portion 21 is arbitrary.

The shape and form of the inner plate body are arbitrary. For example, the outer shape is elliptical in cross section (FIG. 10), and ribs 13a, 13 are provided at symmetrical positions on the outer circumferential surface in the longitudinal direction from the upper end to the lower end.
