JP 2009-155275 A

  However, in the method for producing an oily solid cosmetic product described in Patent Document 1, since only the irregularities of the stamp surface are transferred to the surface of the oily solid cosmetic, a mechanical pattern lacking warmth is obtained. Problem.

  An object of the present invention is to provide an oil-based solid cosmetic having a warm pattern formed so as to protrude from the surface, and a method for producing the same.

  The oily solid cosmetic of the present invention is an oily solid cosmetic containing an oily component, and has a pattern formed to protrude from the surface, and the pattern has bubbles inside a three-dimensional shape, It is characterized by being formed into a foam.

  According to such a configuration, since the pattern has bubbles inside the three-dimensional shape and is formed in a foam shape, a rounded soft impression can be given to the user. Therefore, the oily solid cosmetic can have a warm pattern formed to protrude from the surface.

  The method for producing an oily solid cosmetic of the present invention is a method for producing an oily solid cosmetic containing an oily component, and after filling a cosmetic containing an oily component into a container, a filling step of solidifying the cosmetic. A pattern forming step of forming a foamy pattern so as to protrude from the surface of the cosmetic by bringing the tip of the shaft-shaped body vibrating at the frequency of the ultrasonic range close to the surface of the cosmetic, In the pattern forming step, by moving the shaft following the surface of the cosmetic while maintaining the relative position between the surface of the cosmetic and the tip of the shaft, the pattern is formed inside the three-dimensional shape of the pattern. It is characterized in that a pattern is formed by foaming a cosmetic so as to have bubbles.

  According to such a configuration, the pattern forming step forms the pattern by foaming the cosmetic so as to have bubbles inside the three-dimensional shape of the pattern, so that the pattern has a rounded soft impression. Can be given to the user. Therefore, the oily solid cosmetic can have a warm pattern formed to protrude from the surface.

Here, by vibrating at a frequency in the ultrasonic range, the shaft-like body slightly melts the cosmetic, and foams up to protrude from the surface of the cosmetic to form a pattern. it can. At this time, if the relative position between the surface of the cosmetic and the tip of the shaft is too shallow, the contact area between the cosmetic and the shaft is reduced, so that the cosmetic can be sufficiently foamed. On the other hand, if it is too deep, the contact area between the cosmetic and the shaft-like body will be too large, which will eventually result in resistance to foaming of the cosmetic.
According to the present invention, the pattern forming step comprises: moving the shaft following the surface of the cosmetic while maintaining the relative position between the surface of the cosmetic and the tip of the shaft, thereby forming a three-dimensional pattern of the pattern. Since the pattern is formed by bubbling the cosmetic so as to have air bubbles inside the typical shape, the contact area between the cosmetic and the shaft can be appropriately maintained, and the cosmetic can be sufficiently foamed.

In the present embodiment, the pattern 3 expresses the letters “LOVE” of the alphabet from the left side of the paper to the right side of the paper, but any shape of the pattern may be used as long as it is formed to protrude from the surface. It may be.

  Here, the oily solid cosmetic 1 is a cosmetic containing an oily component. Specifically, the oil-based solid cosmetic 1 is obtained by blending a pigment or the like with a solid fat such as candelilla wax or a liquid oil such as a hydrocarbon as necessary. The oily solid cosmetic 1 has a good affinity for the skin, and is used for makeup cosmetics such as gloss, lipstick, eyeshadow, eyeliner, and oily foundation. In addition, there are various dosage forms such as solid, liquid, paste, and emulsion. In the present embodiment, the oily solid cosmetic 1 maintains solidity at a normal temperature so as to be able to maintain its shape, but melts by heating to 70 degrees or more (more preferably 75 degrees or more) to improve fluidity. What happens is adopted.

  Hereinafter, a method for producing the oily solid cosmetic 1 will be described. In addition, in the manufacturing method of the oily solid cosmetic 1, all the steps may be performed by a manufacturing apparatus, or each step may be performed by a manual operation of an operator.

FIG. 2 is a view showing a state in which a cosmetic dish containing an oil component is filled in a makeup dish.
In order to produce the oily solid cosmetic 1, the cosmetic C containing the oily component is first melted by heating to make it flowable, and as shown in FIG. Fill the makeup dish 2. Thereafter, the cosmetic C filled in the decorative dish 2 is solidified by cooling to maintain a solid state (filling step).

FIG. 3 is a view showing a state in which a foamy pattern is being formed on the surface of the cosmetic.
Next, by bringing the tip of the shaft-shaped body S vibrating at a frequency in the ultrasonic range close to the surface of the cosmetic C filled in the cosmetic dish 2, as shown in FIG. The foamy pattern 3 is formed so as to protrude from the surface (pattern forming step).
In the present embodiment, the shaft body S has a conical tip portion that becomes thinner toward the tip side (see FIG. 4), and is attached to the vibration generator VM. The vibration generator VM vibrates the shaft body S at a frequency in the ultrasonic range. Here, the ultrasonic range refers to a frequency range of 15 kHz or more.

  Here, the shaft-shaped body S vibrates at a frequency in the ultrasonic range, thereby slightly melting the cosmetic C, and raising the pattern 3 by foaming to protrude from the surface of the cosmetic C. Can be formed. At this time, if the relative position between the surface of the cosmetic C and the tip of the shaft S is too shallow, the contact area between the cosmetic C and the shaft S becomes small, so that the cosmetic C is If the cosmetic C is too deep, the contact area between the cosmetic C and the shaft body S will be too large, and the resistance to foam the cosmetic C will be too large. Cannot be lathered enough.

Therefore, in the pattern forming step, while maintaining the relative position between the surface of the cosmetic C and the tip of the shaft S, the shaft S is moved according to the planar surface of the cosmetic C ( The pattern 3 is formed by bubbling the cosmetic C so as to have bubbles inside the three-dimensional shape of the pattern 3 (see the arrow in FIG. 3).
In the present embodiment, the shaft body S is moved from the left side of the drawing to the right side of the drawing so as to draw the letter “LOVE” of the alphabet.

FIG. 4 is a diagram showing a procedure for forming a foamy pattern on the surface of the cosmetic. Specifically, FIG. 4 is a diagram showing an end surface of a BB cross section of FIG.
In the pattern forming step, first, as shown in FIG. 4 (A), the tip of the shaft-shaped body S vibrating at a frequency in the ultrasonic range was brought close to the surface of the cosmetic C filled in the decorative dish 2. State.
Then, the shaft-shaped body S vibrates at a frequency in the ultrasonic range, thereby slightly melting the cosmetic C as shown in FIG. Raise as you do.

Then, while maintaining the relative position between the surface of the cosmetic C and the tip of the shaft S, the shaft S is moved along the surface of the cosmetic C, as shown in FIG. In addition, the pattern 3 can be formed at the position where the shaft S passes.
In the present embodiment, the pattern forming step is performed so that the tip of the shaft S is not immersed in the cosmetic C and the surface of the shaft C is directly contacted with the surface of the cosmetic C. The shaft body S is moved following the surface of the cosmetic C while maintaining the relative position with respect to the tip of S.

  Thus, the oily solid cosmetic 1 can be manufactured by performing each of the steps of the filling step and the pattern forming step.

According to the present embodiment, the following operations and effects can be obtained.
(1) Since the pattern 3 has bubbles inside the three-dimensional shape and is formed in a foam shape, a rounded soft impression can be given to the user. Accordingly, the oily solid cosmetic 1 can have a warm pattern 3 formed so as to protrude from the surface.
(2) In the pattern forming step, the cosmetic C is foamed so as to have bubbles inside the three-dimensional shape of the pattern 3 to form the pattern, so that the pattern 3 gives the user a soft, rounded impression. Can be given to.

(3) In the pattern forming step, the shaft 3 is moved along the surface of the cosmetic C while maintaining the relative position between the surface of the cosmetic C and the tip of the shaft S, thereby forming the pattern 3. Since the cosmetic 3 is foamed so as to have air bubbles inside the three-dimensional shape of the pattern 3 to form the pattern 3, the contact area between the cosmetic C and the shaft body S can be appropriately maintained, and the cosmetic C can be used. Can be lathered well.

It should be noted that the present invention is not limited to the above-described embodiment, and includes modifications and improvements as long as the object of the present invention can be achieved.
For example, in the embodiment, the oily solid cosmetic 1 forms the pattern 3 in the single-color cosmetic C, but the pattern may be formed in a multicolor cosmetic. In this case, the pattern may be formed so as to straddle the boundary of the multicolor cosmetic, or may be formed along the boundary. In short, the pattern only needs to be formed so as to protrude from the surface of the cosmetic.

  Moreover, in the said embodiment, the oil-based solid cosmetic 1 was provided with the pattern 3 formed so that it might protrude from a planar surface. On the other hand, the surface of the oily solid cosmetic may have another shape such as a curved surface, and may have a pattern formed so as to protrude from the surface.

FIG. 5 is a front view and a rear view showing an oil-based solid cosmetic according to a modification of the present invention. Specifically, FIG. 5 (A) is a front view showing the oily solid cosmetic 1A, and FIG. 5 (B) is a rear view showing the oily solid cosmetic 1A.
As shown in FIG. 5, the oil-based solid cosmetic 1A is a substantially columnar lipstick housed in a cylindrical case 2A.

The oily solid cosmetic 1A has a pattern 3A formed so as to protrude from the curved surface. The pattern 3A has bubbles inside a three-dimensional shape, and is formed in a foam shape.
In this modification, the pattern 3A represents the letter "Love" of the alphabet from the front side (see FIG. 5A) to the back side (see FIG. 5B) of the oil-based solid cosmetic 1A. However, the pattern may have any shape as long as it is formed to protrude from the surface.

  In order to manufacture such an oil-based solid cosmetic 1A, the pattern forming step follows the curved surface of the cosmetic while maintaining the relative position between the surface of the cosmetic C and the tip of the shaft S. The pattern 3A may be formed by moving the axial body to foam the cosmetic so as to have bubbles inside the three-dimensional shape of the pattern 3A.

Further, in the above-described embodiment, the shaft-shaped body S has a conical tip that becomes thinner toward the tip, but other shapes such as a column-shaped tip and a plate-shaped tip are used. May be provided.
Further, in the above embodiment, the pattern forming step is performed so that the tip of the shaft S is not immersed in the cosmetic C, and the surface of the shaft C is directly contacted with the surface of the cosmetic C. While maintaining the relative position with respect to the tip of S, the shaft-shaped body S was moved following the surface of the cosmetic C. On the other hand, in the pattern forming step, if the foamy pattern 3 can be formed so as to protrude from the surface of the cosmetic C, the tip of the shaft body S may be slightly immersed in the cosmetic C. Alternatively, the tip of the shaft S may be slightly separated from the surface of the cosmetic C.
