Description

[Detailed description of the invention] [Industrial application field] This invention is for filling makeup cosmetics such as lipstick, lip balm, solid white powder, eye shadow, etc. in a heated molten state from a storage tank to a molding means. Regarding nozzles.

[Prior art]

FIG. 3 shows a lipstick cosmetic filling device according to the prior art.

In the figure, 1 is a fixed storage tank, 2 is a lipstick cosmetic as a make-up cosmetic stored in the tank 1 in a heated and molten state, and the cosmetic 2 consists of an oily base material, a coloring agent, etc. It contains a lipstick ingredient and a pearlescent agent. Reference numeral 3 denotes a stirrer attached to the tank 1, and the stirrer 3 stirs and mixes each component of the lipstick cosmetic 2 while flowing the cosmetic 2 into a flow rate adjustment section 4 provided at the bottom of the tank 1. I'm letting you do it. Reference numeral 5 denotes an inverted conical float mounted to move up and down within the flow rate adjustment section 4. By moving up and down in the direction of the arrow, the float 5 adjusts the flow rate of the cosmetic 2 flowing down into the flow rate adjustment section 4. I'm going.

A filling nozzle 6 is attached to the lower end of the flow rate adjustment section 4 and is used to fill a mold 8, which will be described later, with the cosmetic material 2 flowing down through the flow rate adjustment section 4. A channel 6A having a circumferential diameter of about 7 mm and a length of about 50 mm is defined, and a filling hole 7 is provided at the lower end of the channel 6A.

Further, reference numeral 8 denotes a mold in which a plurality of lipstick molding mold parts 8A, 8A, . During this movement, each mold part
Cosmetic material 2 is filled into 8A through the filling hole 7 of the filling nozzle 6.

In the lipstick cosmetic filling device configured as described above, the cosmetic 2 housed in the storage tank 1 is delivered to each mold part 8 of the mold 8 through the filling hole 7 of the filling nozzle 6.
The lipstick is filled into A and cooled in the mold 8 to be molded into a stick-shaped lipstick.

By the way, the pearlescent agent in the lipstick cosmetic 2 is made by coating mica or the like with titanium oxide, and the oil base material, coloring agent, etc. that make up the lipstick component in the cosmetic 2 are particles of 10 μm or less. In contrast, the particles of pearlescent agents are about 40 to 50 microns. Therefore, the pearlescent agent has a property of settling faster than the lipstick component in the molten cosmetic 2 and easily separating from the lipstick component.

On the other hand, this molten cosmetic 2 tends to be in a laminar flow state while flowing down into the flow path 6A of the filling nozzle 6 through the flow rate adjustment section 4, It has a velocity distribution such that the velocity is maximum at the center of the flow path 6A and the velocity is minimum at the periphery of the flow path 6A.

Therefore, when the cosmetic 2 flows in a laminar flow state in the filling nozzle 6, the pearlescent agent with a high sedimentation speed is concentrated in the center of the flow path 6A, and the lipstick component flows into the flow path. 6A, the pearlescent agent and lipstick component are filled into each mold part 8A of the mold 8 from the filling hole 7 while being unevenly separated.

As a result, in the conventional technology, in a lipstick product molded with the mold 8A, the pearlescent agent and the lipstick component are unevenly separated and solidified in a nonuniformly mixed state, and the pearlescent agent and lipstick component are solidified in a nonuniformly mixed state. This has the disadvantage of causing uneven pearl-like luster and lowering the commercial value.

On the other hand, in order to reverse the unevenness of the pearl-like luster caused by the conventional technology, the inventor stored the lipstick component and the component with a high content of pearlescent agent in separate storage tanks. An attempt was made to simultaneously fill the lipstick component and the pearlescent agent-rich component into each mold part of the mold while keeping them separated through the attached filling nozzles.

When the lipstick component and the pearlescent agent are actively separated and filled into each mold section at the same time, a relatively clear striped pattern is formed with the lipstick component and the pearlescent agent separated. It was discovered that a high value-added lipstick product with a marble-like pattern can be obtained.

However, in order to store the lipstick component and the pearlescent agent-rich component in separate storage tanks in this way, it is necessary to prepare two storage tanks, and it is also necessary to control the temperature of each tank. occurs,
There is a problem that the entire device becomes larger and the manufacturing cost increases significantly.

[Problem that the invention attempts to solve]

The present invention was developed in view of the above-mentioned drawbacks of the prior art, and the problems to be solved by the present invention are as follows:
When filling a make-up cosmetic consisting of a cosmetic component and a pearlescent agent housed in a single storage tank into a molding means, the cosmetic component and the pearlescent agent can be filled while being actively separated. To provide a filling nozzle for make-up cosmetics capable of obtaining high value-added make-up cosmetics having a marble-like pattern.

[Means for solving problems]

The feature of the means adopted by the present invention to solve the above-mentioned problems is that the flow of the make-up cosmetic consisting of cosmetic ingredients and a pearlescent agent is made into a laminar flow state, so that the center part becomes a pearlescent agent,
A flow path means for generating a laminar flow that separates the peripheral portion as a cosmetic component, and a filling nozzle installed at the center of the lower end of the flow path means for flowing out the pearlescent agent separated by the flow path means. and another filling nozzle attached around the lower end of the flow path means for flowing out the cosmetic ingredients separated by the flow path means.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. In the embodiment, the same components as those of the prior art shown in FIG.

In the figure, reference numeral 11 is attached to the lower end of the flow rate adjustment section 4, and is used to fill each mold section 8A of the mold 8 with the lipstick cosmetic 2 flowing down from the storage tank 1 via the flow rate adjustment section 4. The filling cylinder 11 has a diameter of about 7 mm and a length of about 80 mm on the inner periphery.
A flow path 11A of approximately 100 mm is formed, and the flow path 11
A constitutes a channel means for generating laminar flow. Also,
An inclined portion 11B inclined at a predetermined angle is formed at the lower end of the filling cylinder 11. Here, while the lipstick cosmetic 2 flows down in the channel 11A, the flow of the cosmetic 2 is substantially laminar, and the sedimentation rate in the cosmetic 2 is high. It is formed relatively long so that the pearlescent agent is concentrated in the central part of the flow, the lipstick component is concentrated in the peripheral part of the flow, and the pearlescent agent and the lipstick component can be actively separated.

Next, reference numeral 12 designates an elongated filling nozzle located at the center of the lower end of the cylinder 11 and attached to the inclined part 11B, and the upper end of the filling nozzle 12 passes through the channel through the inclined part 11B. It protrudes into the inside of the lipstick cosmetic 2 and is enlarged in diameter into a funnel shape as a pearl luster guide part 12A in the lipstick cosmetic 2. Thus, the filling nozzle 12 concentrates the pearlescent agent separated from the lipstick components in the central portion of the flow path 11A and transfers it to the guiding section 1.
It is designed to flow down into each mold part 8A of the mold 8 from the lower end part 12B while being introduced into the interior through the mold part 2A.

Furthermore, 13 is another elongated filling nozzle located around the lower end of the cylinder 11 and attached to the inclined part 11B, and the upper end of the filling nozzle 13 is arranged at the lowest part of the inclined part 11B. The channel 1 is provided as a lipstick component guiding section 13A in the lipstick cosmetic 2.
Connected to 1A. Thus, the filling nozzle 1
3 introduces the lipstick component concentrated in the peripheral portion of the flow path 11 and separated from the pearl luster into the mold 8 from the lower end 13B through the guide portion 13A.
It is designed to flow down into each mold section 8A.
Here, lipstick cosmetic filling nozzle 1 of this embodiment
4 is a filling cylinder 11, filling nozzles 12 and 13
Consists of etc.

Next, the operation of the lipstick cosmetic filling nozzle 14 configured as described above will be described.

The flow of the lipstick cosmetic 2 flowing down into the cylindrical body 11 via the flow rate adjustment part 4 is made into a substantially laminar flow state while passing through the flow path 11A, and the pearls in the cosmetic 2 are The brightener is concentrated in the central part of the flow,
The lipstick component becomes concentrated in the peripheral portion of the flow, and as a result, the pearlescent agent and the lipstick component reach the lower end of the flow path 11A in a desired separated state. The pearlescent agent concentrated in the central part is introduced into one filling nozzle 12 via the guide part 12A, while the lipstick component concentrated in the peripheral part flows along the slope part 11B and is introduced into the first filling nozzle 12 via the guide part 13A. and is introduced into another filling nozzle 13. The pearlescent agent and lipstick component thus introduced separately into one filling nozzle 12 and the other filling nozzle 13 are separated from each other at the lower ends 12 of the filling nozzles 12 and 13.
Flowing down almost simultaneously from A and 13A, mold 8
is filled into each mold part 8A.

As a result, in almost the same way as when the lipstick component and the pearlescent agent-rich component are stored in separate storage tanks and are separated as desired and simultaneously filled into each mold section, the lipstick component and the pearlescent agent-rich component are stored in separate storage tanks. A high value-added lipstick product with a marble-like pattern in which the ingredients and the pearlescent agent form a striped pattern is obtained.

In addition, in the above embodiment, one filling nozzle 1
2 and the other filling nozzle 13 depending on the contents of the lipstick component and the pearlescent agent in the lipstick cosmetic 2, the lipstick component and the pearlescent agent can be further separated. The marble-like pattern in lipstick products can be made more vivid. In this case, since the content of the pearlescent agent in the lipstick cosmetic 2 is usually 5 to 20%, the aperture ratio of one filling nozzle 12 and the other filling nozzle 13 should be set according to the above content. Bye.

Further, in the above embodiment, only one other filling nozzle 13 is attached to the inclined plate portion 11B, but instead of this, a plurality of filling nozzles 13 may be arranged around the lower end of the flow path 11A. In this case, the inclined portion 11B is not necessarily required, and a member for closing the lower end of the flow path 11A and supporting each filling nozzle 12, 13 may be provided.

Further, in the above embodiment, the lipstick cosmetic 2 was explained as an example, but the present invention is not limited thereto, but can also be applied to make-up cosmetics such as lip cream, solid white powder, and eye shadow. On the other hand, although the mold 8 is used as an example of the molding means, other molding means such as an automatic molding machine may be used.

[Effect of idea]

As detailed above, according to the present invention, the flow path means for generating a laminar flow makes the flow of makeup cosmetics into a laminar flow state, so that the center part becomes a pearl brightening agent and the peripheral part is separated as a cosmetic component. a filling nozzle installed at the center of the lower end of the channel means for flowing out the pearlescent agent separated by the channel means; Since another filling nozzle is installed around the lower end of the flow path means, the pearl luster and cosmetic ingredients can be actively separated and filled into the molding means, resulting in a marble-like pattern. A make-up cosmetic product with high added value can be obtained.
