Description

Description: TECHNICAL FIELD The present invention relates to a paper stick-shaped cosmetic in which a stick-shaped cosmetic such as lipstick, foundation, eye shadow, etc. is removably wound on its outer peripheral surface with paper.

(Prior Art) Various cosmetics having a structure in which an outer peripheral portion of a stick-shaped cosmetic is covered with a shaft are known. Such a cosmetic generally has a problem that the liquid component contained in the internal cosmetic permeates into the shaft to deteriorate the quality of the cosmetic.

Conventionally, in order to solve this problem, for example, JP-A-58-
As disclosed in Japanese Patent No. 188811, cosmetics having a structure in which an aluminum vapor deposition film or the like is sandwiched between a shaft and an inner core material have been devised.

However, in the case where the shaft is made of wood as in this known example, when exposing the internal cosmetics, the shaft had to be shaved first, and then the aluminum vapor deposition film or the like had to be peeled off, which was extremely troublesome. . Also, in the case of manufacturing, the length of the semicircular groove provided symmetrically in the axial direction of the inner flat surface of the pair of half-divided wooden shafts, and the length of the end facing the semicircular groove of the flat surface to the aluminum It requires a process of adhering a vapor-deposited film or the like, sandwiching the kneaded core material constituting the cosmetic material with the wooden shaft, and performing pressure bonding, which is extremely troublesome. Further, if the wooden shafts are not joined securely, the joining of the aluminum vapor deposition film or the like will be incomplete, and the liquid component of the cosmetic will easily exude from there.

(Problems to be Solved by the Invention) The present invention has a means for preventing a liquid component of an internal cosmetic from penetrating into an outer shaft, and can prevent deterioration of the cosmetic, and prevent the deterioration thereof. When the means exposes the cosmetics, the cosmetics can be exposed smoothly without disturbing, and the production is simple, and moreover, the seams where the liquid component of the internal cosmetics exudes can be eliminated. The purpose of the present invention is to provide a simple paper stick cosmetic.

(Means for Solving the Problems) In order to achieve the above object, the paper rod-shaped cosmetic of the present invention is a paper having a thin film layer of aluminum formed at one end, and a portion having the thin aluminum film layer is an inner peripheral surface. The outer shaft is formed by winding it in a tubular shape, and a stick-shaped cosmetic material whose outer peripheral portion is wrapped by the outer shaft to bring the outer peripheral surface into contact with the aluminum thin film layer of the outer shaft.

Here, as a means for forming a thin film layer of aluminum on the inner peripheral surface of the jacket shaft, there are methods such as transfer such as hot stamping, vapor deposition, and lamination of a laminate of aluminum or an aluminum film and a film of another material. Can be adopted. When actually forming a thin film layer of aluminum, it is easier to perform it in a flat state before the paper on the outer shaft is wound. A layer such as a thin film or a film made of a resin or another material may be provided on the surface of the aluminum thin film layer, between the aluminum thin film layer and the paper of the jacket shaft, or both. Further, in order to prevent pinholes in the aluminum thin film, the aluminum thin film layers may be provided in double, triple or more layers. The thickness of the aluminum thin film layer is in the range of 0.003 to 30 μm.

The method of providing the stick-shaped cosmetic material inside the outer shaft is a method of winding paper on the outer peripheral surface of the stick-shaped cosmetic material, or a method of forming a hollow cylindrical outer shaft in advance and inserting the stick-shaped cosmetic material into the inside. It is possible to adopt a method in which a hollow cylindrical outer shaft is formed in advance, and a cosmetic material is heated in a molten state to be injected and filled therein, and then the cosmetic material is cooled and solidified into a rod shape. is there.

(Example) Example 1 As shown in FIG. 1, a large number of cut lines 1 such as perforations having a rectangular shape and slightly inclined with respect to its long side are provided in parallel at a constant interval, and along one short side. Hole 2 between each tear line 1
And a separating thread 3 is attached to the inside of the hole 2 in parallel with the short side, and a paper 4 is prepared by laminating an aluminum film having a thickness of 7 μm on the entire inner surface. Wrap the 10 mm plastic rod around the short side opposite to the short side on which the hole 2 is provided, with the short side on the center side, and finally on the short side on which the outermost hole 2 in the radial direction is provided. The end edges are adhered to form a scroll, and then the outer peripheral surface thereof is decorated by printing or the like, and then the plastic rod is pulled out to form a hollow cylindrical jacket shaft 5. One end of the jacket shaft 5 was sealed by fitting a plug into the opening and then sealing the lipstick consisting of the composition shown in Table 1 below, which became solid at room temperature, to 80 ° C. By injecting from the opening on the side not plugged inside and filling it, it is cooled and solidified to form a rod As shown in FIGS. 2 and 3,
Paper wrapped stick lipstick 8 comprising an outer shaft 5 wound with paper 4 and a rod-shaped lipstick 6 inside thereof, and an aluminum thin film layer 7 formed on the inner peripheral surface of the outer shaft 5 in contact with the outer peripheral surface of the rod-shaped lipstick 6. Was completed.

Example 2 An aluminum film was not entirely laminated on the inner surface, but instead, a side end portion over a distance of 40 mm from the short side opposite to the side provided with the holes 2 to the inside, that is, a in FIG. 1 was used. The outer shaft 5 is formed in the same manner as in Example 1 by using the same paper 4 as that used in Example 1 above, except that an aluminum film having a thickness of 10 μm is transferred to the inner surface of the range indicated by At the same time, a stick-shaped lipstick 6 was formed therein to complete a paper stick-shaped lipstick 8.

Next, except that the inner surface was left as the base material, the same paper used in the above-mentioned embodiment was used to form the same jacket shaft as that in the above-mentioned embodiment, and the same outer shaft as that in the above-mentioned embodiment was formed therein. A bar-shaped lipstick of Comparative Example was produced by forming a bar-shaped lipstick, and the paper-bar-shaped lipstick of each of Comparative Example and Example 1 and Example 2 was left in a constant temperature bath at 40 ° C. for 1 week. It was examined whether the liquid component exuded on the paper of the outer shaft and whether the property of the stick-shaped lipstick changed. as a result,
In the paper-rolled stick-shaped lipsticks of Examples 1 and 2, no bleeding of the liquid component of the lipstick on the paper on the outer shaft was found, and no change was observed in the stick-shaped lipstick properties. On the other hand, in the paper-rolled stick lipstick of the comparative example, the liquid component of the lipstick bleeds to the outermost wound portion of the outer shaft and the paper is discolored, and the stick-shaped lipstick changes in diameter. Was there.

Table 1 Lipstick formulations Castor oil 44.8 (wt%) Lanolin fatty acid isopropyl 7.0 Beeswax beeswax 7.5 Ozokerite 3.0 Candelilla 7.5 Red 26 No. 3.2 Red 230 (1) Aluminum lake 0.3 Mica titanium 6.5 dl-α-tocopherol acetate 0.2 Diisostearyl malate 10.0 Isopropyl palmitate 10.0 (Advantageous effects) The present invention is as described above, and since the aluminum thin film tank is formed on the inner peripheral surface of the outer shaft of the paper which is in contact with the outer peripheral surface of the stick cosmetic, It is possible to prevent the contained liquid component from being absorbed by the paper of the outer shaft and prevent the change in the properties of the stick-shaped cosmetic material. In other words, various stick-shaped cosmetics containing a sufficient amount of a liquid component, soft and easy to spread, and excellent in feeling of use can be manufactured into a paper roll.

Also, when the paper of the outer shaft is peeled off, the aluminum thin film layer is also removed together, so there is no trouble of peeling the aluminum thin film layer separately from the outer coat layer, and it is easy to expose the stick-shaped cosmetic inside, and the aluminum thin film The layers don't get in the way.

Further, since the aluminum thin film layer can be formed on the inner peripheral surface of the paper by simply winding the paper in a tubular shape, the stick-shaped cosmetic material and the paper of the outer shaft can be separated from each other.

Further, since the aluminum thin film layer on the inner peripheral surface cannot be joined by wrapping the paper, there is no space for the liquid component of the stick-shaped cosmetic material to seep out, and the above-mentioned effect of preventing penetration into the envelope shaft is remarkable.
