CLEMENT HACK CO,, 601 St. Kilda Road, Melbourne, Victoria 3004, Australia, Actual Inventor: Address for Service: Complete Specification for the invention entitled: PROCESS FOR PRODUCING COSMETIC CARDS PACKED WITH POWDERY SOLID COSMETICS The following statement is a full description of this invention including the best method of performing it known to me:if V i LOGD SUDLjC bou e F" D S Background of the Invention: Field of the Invention: The present invention relates to a process for producing very thin cosmetic cards, without any pressing operation, on which powdery solid cosmetics are placed in prearranged cavities.

Description of the Related Art: So far, cosmetics as merchandise have mostly been offered in a solid form which is packingly placed in the inside of a hollow vessel.

S( The packing of cosmetics in said vessels has commonly been performed by mixing and agitating the cosmetics with a binder and by compactly packing the 4: Smixture into the vessel, followed by applying pressure 1t °o onto the mixture.

S1,So far known vessels for packing with cosmetics a o a have been prepared to contain the cosmetics usually to a thickness of 3 to 5 mm or more. A thinner container 0 0 S0 9 carrying a thinner layer of cosmetics in their cavities 00000o (designated hereinafter as cosmetic card) did not appear excluding in exceptional cases.

Thus, a cosmetic card as commercial article in which a cosmetic is placed in a very shallow cavity did not appear previously. The reason is that that kind of articles were demanded scarcely but more basically the previous pressing operation was not sufficiently useful to p roduce said product so as to afford at least necessary, 2 Osamu Kawamura, President This form may be completed and fled after the filing of a patent application but the form must no jbe signed until after it has been completely filled in as indicatec by the marginal notes.

a~ qualities to the cosmetic.

Mocr particularly, when the cosmetic card which is packed with solid cosmetic is prepared by the conventional pressing process, strength of the solid is decreased with the decrease of thickness of the solid layer. The pressing treatment does not suffice to give an appropriate strength to the solid. Further, the pressing is also difficult to apply if the thin and broad layer of the cosmetic is sufficiently levelled before the pressing. For illustration, if a certain cosmetic placed in a cavity on a cosmetic card is so pressed as to produce such a degree of hardness (or rather softness) that allows ordinary application of a puff, a cosmetic tip or a brush, the layer of the cosmetic material Cnight be readily broken while being used or carried. On the contrary, if the cosmetic material is pressed to such a hardness as not to be broken while being carried, the resulting cosmetic layer will be too hard to apply a pu

C

tip and brush. In either case, the cosmetic is prepared unappropriately to the practical use. The amount solve of the binder may be increased to dissolve the problem of peeling and breakage of the cosmetic material from the vessel. But, on the other hand, an increased amount of binder will result in increased hardness, which in turn causes difficulty in treating the cosmetic with a puff and also in applying it to facial skin.

ii 3 of a card-like container is not for the practical use except for some exceptional cases.

Make-up cosmetics composed of eye-shadow, cheek rouge, foundation and others in a sing)e case are nowadays available in variety. These materials assume almost to 30 times of repeated uses for each color. They are prepared by the pressing process, but there has occurred no particular problem because of their relatively long and abundant application.

000000 o f However, recent trend of demanders is of a 0 manifold character and requires rather frequent changes.

0 0 0 o o S2oo Most customers desire to hold a variety of such cosmetics, o o sometimes wish to purchase small quantities of the 0 0 cosmetics of so-called adventurous colors which are only 00o unusually used. These demands of users cannot be met 0 0 0 by the previous cosmetic prepared by the conventional 0 0 pressing process in which each cosmetic article is 0 0 0 0 0 0 supposed to be used 20 to 30 times. More probably, customers may be discouraged from buying such cosmetics S00o on account of their prices or the articles purchased 0 0o 100 00 0 a may be abandoned after a few repeated uses.

Summary of the Invention:

I

The present invention has been made from the scope mentioned above. It aims at substantially providing a card-shaped container of cosmetics which holds a relatively small amount of the cosmetic and permits the cosmetics to be carried for use.

Further object of the present invention is to provide a process for producing cosmetic cards which are ,;uitable for color samples of cosmetics. Formerly, color samples of cosmetics were prepared either by printing on paper to show the tone of color or from commercial products themselves, and consumers were requested to respond with respect to their color. These preparations of color samples required a high cost in the former and evoked psychological hesitation in the latter with which a plurality of people used a single and same sample. In this connection, however, the mentioned cosmetic cards provided by the present invention which can be consumed in a few uses will completely solve the above-mentioned problem. The cosmetic samples which the present invention can produce as of a small quantity and of a light weight in the form of a card permit themselves to be delivered and distributed rather freely, for instance in the form of a direct mail.

The present invention has been developed to realize the above-mentioned aims, and succeeded in producing very thin cosmetic cards packed with powdery solid cosmetics.

Accordingly the present invention provides a process for producing cosmetic sheets packed with solid cosmetics, comprising providing a sheet of card-like

The card-like vessel above which provides 0 a .0;a cavities for accommodating the cosmetic material, as 0 01 s. suggested from its usage, should be formed preferably in 0 0 Sthe form of as thin and flat plate as possible. In

I

addition, since the cavities are supposed to accommodate cosmetics containing volatile solvents, materials such as .0 d 1 paper, cloths and unwoven tissues are not suitable to form co 0S the cards. Suitable materials from which the cards are 0o 00 made generally include synthetic high polymers such as 20 polyethylene, vinyl chloride, polystyrene, polypropylene, 0 oo.oo ABS, acryl and polyamide, polyethyleneterephthalate4 polyacetal, polycarbonate, melamine, fluorine, urea and epoxy resins; or metals such as aluminum, copper, iron, stainless steel and brass, and composite materials thereof.

plated with aluminum by the adhesion by vacuum evaporation to produce a resinous mirror and is cut to form cavities to fill osmetics.

According to the process of the preset invention, the cosmetic in a cavity shrinks on drying to a half of the original depth. This defect is improved as follows. A synthetic resinous frame with an opening fitted to the cavity is placed on a card with the opening opposite to the cavity, and an appropriate amount of 000000oooo 0 0 0 o cosmetic is placed. This is thoroughly dried. The frame 0 0 000 0 o oo is removed to obtain a levelled surface. This method 0 0o 0 0 o 000 of applying cosmetics permits the cosmetic cards to be 0090 o00.00 made further thinner, if a certain amount of cosmetic 0 0 is to be contained in the cavity.

0 00 °000 The cosmetics to which the present invention oo 0 o is applied may be 'ry cosmetic so long as it is of a o o usually employed powdery solid. It may be one for Q 0O 0 eye-shadow, cheek rouge, or foundation, and not restricted by its use. The cosmetic itself may be composed fromi 00 0 00 powders of common usage in the field of cosmetic industry, 06oo00 0 rrespective of hydrophilic or water repellent. The materials include, for example, fillers such as talc, kaolin, mica and sericite; white pigments such as titanium oxide; iron oxide of red, yellow and black colors, ultramarine, prussian blue, chromic pigments; organic pigments (such as D C Red No. 30, Phthalocyanine Blue, Ext D C Yellow No. 5 and others); pearl pigments such as titanium-mica pearl, titanium-mica-organic pigment 7

The binders to be mixed to the cosmetics of this invention may be anyone which is usually employed in the field of cosmetic industry. They include hydrocarbons such as liquid paraffin, squalane, vaseline, microcrystal wax and ceresine; higher fatty acids such as stearic, oleic, palmitic and myristic acids; higher alcohols such as cetyli, oleyl and stearyl alcohols; asters such as isopropylpalmitate, isopropylmyristate, 2-octyldodecylmyTistate; glycerides such as monostearic, 2-ethyihexanetriglyceride and coconut oil aliphatic, acid txiglyceride; silicone oils such as dimethyl polysiloaxane and phenyl-methyl polysiloxane; surfactants such as sorbitan sesquioleate, polyoxyethylene cetylether, polyoxyethylene oleylether phosphoric avid and diglycerol

'I

monolaurate; and natural oils and fats such as lanolin, lecithin, bees wax and batyl alcohol.

These binders are added in an amount of 3 to preferably 10 to 30%, by weight of cosmetics. When the binder is added in an amount less than 3% by weight, the mixture is more apt to be peeled from the vessel and 8 *1 broken and, on the other hand, when it is 'used in an amount more than 50% by weight, it becomes diflicult to take the cosmetic out of the card using puffs tips and brushes.

The volatile kolvents to be used in the present invention for the purpose of achieving better packing of the cosmetics into the cavities on the card-like vessel may be any of ordinary volatile solvents. Particularly preferred among them are ethyl alcohol, isopropyl alcohol, O0 0000 0 0 0 0 000 hydrocarbons having a boiling point between 100 and 200 0

000 0 OoQO approximately, silicone oils of boiling points between 100 0 0o °a and 200 0 C approximately, cyclic silicones and water, but 0000 oooooo hydrocarbons of the boiling points between 150 to 200 0

0 0 approximately and tetramers of cyclic silicone are more 0 o0 preferred because of their speed of evaporation, 0 00 0 0 inflammability, viscosity, dissolution capability and 0 o0 their odor.

1) 0 0 00 0 Suitable viscosity of solvent is about 0.5 to 10 cs to give an adequate fluidity to the cosmetics.

00 0 0 0 000 A viscosity higher than 10 makes it difficult to pack a 0060000 0 0 cavity with the cosmetic and to obtain a levelled iurface.

On the other hand, when the viscosity is lowered by adding more solvent, it takes more time before being dried, results in a worse wor!..Ing condition and a less net amount of the dried cosmetic, though the packing and levelling become easier. Considering these effects, a viscosity less than 200 cs and use of a solvent in a 0.5 to 3 times as much amount as cosmetic are mostly recommended.

-9e cc Cc c c 0 *0Q4 D 0 .In -this invention the depth of cavities which are packed with cosmetics are made to about 0.1 -to 3 mmt, because a thickness of dried solid cosmritin-s of approximately 0.01 to 1.5 mm is desired. If 'the -thickness exceeds 1.5 mm, the solid cosmetics are more fragile against breaking force, while t thickness less than 0.01 mm does not contain a necessary minimum amount of the cosmetic material. On the other hand, if the opening area of cavities is too large, the solid cosmetic may be less resistive against breakage. Thus, an area less than 50, preferably 30, cm 2.s recommended.

The solid cosmetics prepared by the process of this invention, as they are in cavities, exhibit suitable resistance against breakage and excellent properties as cosmetic, as is experimentally shown in Ex.,=ples to be described later. The reason is that the soli~d cosmetics packing the cavities hold more empty spaces, hence small er density, than those prepared by the pressing process. There-fore, they are better transferred to puffs and brushes and spread better over skins uniformly. The fluidized cosmetic flows, well into small cavities, and is believed to result in getting wet mutually with the inside wall of the cavities, increasing the adhesion force. Accord~ing to the present invention again, a thicker layer of a cosmetic material has an inclination to reduce the resistance against breaking force, and,~ this is presumably due to the weaker adhesive capability of the cosmetic particles to each other, owing I

A-J

to the low density (usually 1 0.7 to Also from this point, the above-described depth is approved of the cavities on the cosmetic cards which are produced by the process of the present invention.

In the present invention, the drying operation which is carried out after cavities on card-like vessel are packed with the fluidized cosmetics may be performed in accordance with commonly employed drying operations.

However, use of a far infrared ceramic heater is particularly preferable in the effectiveness and S anti-explosive nature.

Detailed Description of the Preferred Embodiments: In the following, the present invention will be described on the basis of the embodiments thereof with reference to the accompanying drawings.

I A Fig. 1 is a flow sheet of operations according to which this invention is executed. Actually in this invention, first predetermined cos are prepared.

Raw material powders and a binder are mixed and agitated, transferred to a crashing machine such as hammer mill, to get homogenized. A volatile solvent in an amount necessary and sufficient for fluidization is added and mixed. The mixture is then poured into cavity 2 on the card-like vessel I in Fig. 2, until it fills up the cavity, and dried by removing the solvent either at room temperature or by heating, to obtain products of the cosmetic cards.

Concerning the above statement, the amounts of cosmetics per a single application are usually 5 to mg of eye-shadow, 10 to 25 mg of check rouge and 150 0 to 300 mg of foundation. In this example, amounts of 0 00 cosmetics appropriate to 2 or 3 times of application 000 0 Q were supposed, and vessels for cosmetics shown in Fig. 2 wore prepared of aluminum and plastics. In Fig. 2, the 00 0 card-like vessel I has a thickness of 1 mm, dept' of 0 th cavities is 0.7 mm, and the areas of the cavitLeo for foundation 2, cheek rouge 3 and eye-shadow 4 are about 30, 2 and 1.5 cm 2 respectively.

Embodiment I The cosmetic for foundation of the composition described below in an amount of 100 parts by weight was mixed with 200 parts by weight of a volatile solvent 1.

<4 (cyclic silicone, a tetramer). Cavity 2 on a card-like vessel 1 of aluminum was packed with the above mixture which was then dried with a far infrared ceramic heater for 15 min. at L.e ambient temperature The depth or thickness of the cosmetic for foundation in the cavity 2 was varied as described in Table 1, and the dropping test was conducted for each sampla. Results are also included in Table 1. Criterion for the dropping test is usually 5 or so. In the present tests, those samples having a less than 1.5 mm thickness met the crit rion (see Table When the area of cavity was reduced to 1.5 cm the same tests for the drop resistance proved better results (see Table The test for resistance against breakage was conducted by dro' 4n tne card-like vessel repeatedly from a height of 5t' cm onto a glass plate and the number of repetitions at 'hich the sample cosmetic was broken was noted.
