Description

[Detailed Description of the Invention] The present invention relates to a lipstick container, and more specifically, with a cap for lipstick molding mold fitted into the container body, molten lipstick ingredients are poured between the container body and the lower part of the cap. The present invention relates to a lipstick container which is filled with lipstick ingredients and is separated from the cap when the lipstick is lowered by rotating the container body after the lipstick ingredients have solidified.

Conventionally, there are some well-known lipstick containers of this kind, but all of these have a structure in which the cap for the lipstick molding mold is fixed and the lipstick is lowered after molding, so the surface layer of the lipstick is removed while the lipstick is being lowered. There was a problem in that the surface layer was rubbed by the inner surface of the cap and the surface layer was peeled off or damaged.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to push down the lipstick molding cap by rotating the container body, thereby allowing the molded lipstick to be molded into the cap. To provide a lipstick container which can be lowered without peeling off the surface layer or being damaged.

Hereinafter, a lipstick container according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in the exploded view of FIG. 1, the lipstick container of the present invention is composed of a rotating body 1, an outer cylinder 2, an inner plate 3, and a lipstick mold cap 4.

The rotating body 1 consists of a lower operation cylinder part 5 and an upper operation cylinder part 6 with a step so as to have a smaller diameter than the lower operation cylinder part 5. A vertical slit 7 extending in the vertical direction, and horizontal slits 8a and 8b extending in opposite directions along the circumferential direction at the upper and lower ends of the vertical slit 7 are formed. Further, an annular collar 9 is provided protruding from the outer circumferential edge of the upper end of the actuating cylinder portion 6, and a first wavy ring 10 which is wavy in the vertical direction is formed at the inner circumferential edge of the upper end.

The outer cylinder 2 is a cylindrical body that fits into the operating cylinder part 6 of the rotary main body 1, and has a spiral groove 11 formed on its inner surface, and a large number of small longitudinal grooves 12 arranged in parallel on the outer peripheral surface of its upper end.

The inner plate 3 is for holding the base of a lipstick, which will be described later, and has a protrusion 13 formed on its central outer surface.
In addition, an annular rib 14 is protruded from the center of the inner surface to ensure firm engagement with the molded lipstick, and the outer peripheral edge of the upper end is a small-diameter ring portion 1 with a step.
5.

The lipstick mold cap 4 is formed as an annular frame 16 with a large diameter at the lower end, and the inner circumferential surface of the annular frame 16 engages with the small vertical groove 12 formed on the outer circumferential surface of the upper end of the outer tube 2. A large number of small vertical protrusions 17 that can be combined are arranged in parallel. A second wavy ring 18 that is vertically wavy is integrally formed on the inner side of the annular frame 16, and the wavy pitch and shape of the second wavy ring 18 are the same as those of the first wavy ring 16. It is the same as that of Further, a stepped annular groove 19 is formed in the inner peripheral portion of the annular frame 16.

Next, the assembly of the above-mentioned members will be explained. First, the inner plate 3 is inserted from the upper opening of the rotary main body 1 by aligning the protrusion 13 of the inner plate 3 with the vertical slit 7. Next, the outer cylinder 2 is attached to the rotary main body 1 from above, and while the outer cylinder 2 is rotated, the spiral groove 11 is engaged with the end of the protrusion 13 protruding outward from the vertical slit 7 of the inner plate 3. match. As a result, the mechanism for raising and lowering the inner tray 3 has been assembled. Here, the operating cylinder part 5 of the rotating body 1 is rotated relative to the outer cylinder 2, the inner plate 3 is raised to the highest position, and then the protrusion 13 of the inner plate 3 is moved to the side of the horizontal slit 8a above the operating cylinder part 5. Position it at the end. In this state, as shown in FIG. At the same time as engaging the small groove 12, the cap 1
The convex portion of the second corrugated ring 18 formed at 4 is engaged with the recessed portion of the first corrugated ring 10 formed at the upper end of the rotating body 1. At this time, the upper end ring part 1 of the middle plate 3
5 comes to engage with an annular groove 19 at the lower inner end of the cap 4.

By assembling each member as described above,
Preparations for filling the cap 4 with molten lipstick ingredients are now complete.

In order to fill the lipstick component, as shown in FIG. It is located at the upper open end in FIG. From this state, the molten lipstick ingredients are filled into the inner tray 3 and the cap 4, and then the nozzle 20
Pull it out. After the lipstick components are cooled and solidified, the rotating body 1 is rotated relative to the outer cylinder 2. In this direction of rotation, the protrusion 13 of the inner plate 3 is aligned with the horizontal slit 8 of the rotating body 1.
This is the direction of arrow A in FIG. 1, which moves from the side end of a to the vertical slit 7 side. At this time, since the outer cylinder 2 and the cap 4 are non-rotatably engaged with each other, the first corrugated ring 10 of the rotating body 1 slides against the second corrugated ring 18 of the cap 4. , the cap 4 is forcibly pressed from the engaged state shown in FIG. 4a to the state shown in FIG. 4b. This cap 4 and outer cylinder 2 have a small vertical protrusion 17.
Since the second corrugated ring 18 is pressed by the first corrugated ring 10, the cap 4 is separated from the outer cylinder 2. Will have to move. Due to this movement, an annular groove 1 is formed at the inner lower end of the cap 4.
9 is separated from the ring part 15 at the upper end of the inner tray 3, and a gap is formed between the two, so that outside air flows through the gap between the inner surface of the cap 4 and the molded lipstick 21. The lipstick 21 flows between the cap 4 and the lipstick 21 to facilitate lowering the lipstick 21 relative to the cap 4.

Preferably, when rotating the rotary body 1 to separate the cap 4 from the outer cylinder 2 as described above, the molded lipstick 21 is rubbed on the inner surface of the cap by rotating within the cap 4. In order to prevent this, the length l of the horizontal slit 8a of the rotating body 1 is adjusted as shown in FIGS. 4 and 5.
is equal to or longer than the pitch P between the concavities and convexities of each corrugated ring 10, 18.

In addition, in order to automatically separate the cap 4 from the outer cylinder 2 by rotating the rotary body 1 with the cap 4 facing downward, the small vertical protrusion 17 of the cap 4 should be The amount of engagement with the small groove 12, ie, the depth of engagement d, is made smaller than the height h between the concave and convex portions of each of the corrugated rings 10 and 18. In this way, as shown in FIG. 6, while the rotary body 1 is rotated and the molded lipstick 21 is stored in the rotary body 1, the cap 4 is automatically separated from the outer cylinder 2 and falls. It turns out.

On the other hand, if a method is adopted in which the rotary body 1 is rotated with the cap 4 facing upward to separate the cap 4 from the outer tube 2, the cap is removed while the rotary body is rotated and the lipstick is lowered. 4 and the outer cylinder 2 is released, there is a risk that the cap will tilt and damage the lipstick that is being lowered. It is better to make it bigger than.

As described above, in the lipstick container of the present invention, the cap 4 for the lipstick molding mold is non-rotatably engaged with the outer cylinder 2, and the first corrugated ring 10 formed on the rotating body 1 is formed on the cap 4. Second waveform ring 1
8, the inner tray 3 and cap 4 are filled with molten lipstick ingredients and solidified, and then the rotary body 1 is rotated relative to the outer cylinder 2, thereby transferring the cap 4 to the outer cylinder 2. and move it in the direction of separating it from the inner tray 3, allowing outside air to flow between the cap 4 and the lipstick 21, and by the subsequent operation of the rotary main body 1, the lipstick 2
This eliminates the conventional defect that lipstick sticks closely to the inner surface of the cap 4 and the surface layer is peeled off and damaged when the number 1 is lowered.

Also, the pitch p and height h between the uneven portions of each corrugated ring 10, 18 are the length l in the circumferential direction of the horizontal slit 8a,
By determining the engagement depth d between the cap and the outer tube 2, it is possible to prevent the lipstick 21 from rotating within the cap when the cap 4 is separated from the outer tube 2, and to prevent the lipstick 21 from being retracted. This allows the cap 4 to separate and fall automatically.
