【考案の詳細な説明】
本考案は携帯用スポンジに係り、更に詳細には
水性化粧品の塗布、化粧落し、或るいは洗顔用等
に好適なポリビニルアセタール（以下PVAtと略
記する）系スポンジに関する。[Detailed Description of the Invention] The present invention relates to a portable sponge, and more particularly to a polyvinyl acetal (hereinafter abbreviated as PVAt) sponge suitable for applying water-based cosmetics, removing makeup, or washing the face.
PVAt系スポンジは親水性にすぐれ適度の弾性
と柔軟性を有し、肌とのなじみ、フイツト性が極
めて良好なため、水性化粧品塗布用のパフ、化粧
落し用素材、洗顔用素材等として従来から様々な
形態で商品化され利用度も高いものである。 PVAt-based sponges have excellent hydrophilicity, moderate elasticity and flexibility, and have extremely good compatibility with the skin and fit, so they have traditionally been used as puffs for applying water-based cosmetics, makeup removers, facial cleansing materials, etc. It has been commercialized in various forms and is highly used.
しかし、その反面PVAt系スポンジは乾燥状態

の異なるものになる性質があり、使用に際しては
水に浸漬し、柔軟な状態にもどす必要がある。即
ちPVAt系スポンジは、水と接触するとその気孔
構造が毛細管現象をおこし、水を強制的に吸上げ
る。従つてその吸水速度は相当速いものである
が、素材の水分含有量が50％以下、即ち半乾燥あ

め素材を湿潤状態にしておく必要があつた。また
素材の体積に相当する程度の多量の水分を急速に
吸収させるためには手あるいは適当な器材で湿潤
状態の素材を圧縮し、吸収する水中で復元させて
強制的に水分を吸収させると云うように使用に手
間を要していた。 However, on the other hand, when PVAt sponges become dry, they harden and lose their elasticity and flexibility, resulting in completely different physical properties. Before use, they must be immersed in water to return to a flexible state. In other words, when a PVAt sponge comes into contact with water, its pore structure causes a capillary phenomenon, forcibly absorbing water. Therefore, its water absorption rate is quite fast, but when the moisture content of the material is less than 50%, that is, in a semi-dry or dry state, its water absorption rate becomes extremely slow. Therefore, in order to use it for water absorption purposes, it was necessary to keep the material in a wet state beforehand. In addition, in order to rapidly absorb a large amount of water equivalent to the volume of the material, the wet material is compressed by hand or with a suitable device, and then restored in the absorbing water to force the material to absorb the water. It took a lot of effort to use.
本考案の目的は、水あるいは水を主成分とする
液体、エマルジヨン、分散液中に浸漬することに
より瞬時に膨張拡大して柔軟且つ弾性的性質を発
現するPVAt系スポンジを提供するにある。 An object of the present invention is to provide a PVAt sponge that instantly expands and expands when immersed in water or a water-based liquid, emulsion, or dispersion to exhibit soft and elastic properties.
上述の目的は乾燥硬化状態のポリビニルアセタ

ピースから構成され、前記スポンジピースは微少
連結部分を残して切込線が入り、微少部分を介し

てなる携帯用スポンジにより達成される。 The above-mentioned object is a compression-molded body of a polyvinyl acetal porous material in a dry and hardened state, and the compression-molded body is composed of sponge pieces having at least one edge forming an acute angle, and the sponge pieces have minute connecting portions. This is achieved by a portable sponge that is integrally formed by making a cut line and connecting the sponge pieces through a small portion.
本考案者らはPVAt系多孔質体を水分の含有率
50％以下すなわち実質的には乾燥硬化の状態下で
外部加熱することなく略室温下で圧縮すると極め
て密な組成の圧縮成形体が得られ、かゝる成形体
は極めて迅速に水分を吸収し柔軟且つ弾性に富ん
だものになるとの知見を得た。ここで云う圧縮率
とは次式により表わされるものである。 The present inventors determined the moisture content of the PVAt-based porous material.
When compressed at approximately room temperature without external heating under conditions of 50% or less, that is, in a substantially dry-cured state, a compression molded body with an extremely dense composition is obtained, and such a molded body absorbs moisture extremely quickly. It was found that the material is flexible and highly elastic. The compression ratio referred to here is expressed by the following equation.
圧縮率（％）＝Ａ−Ｂ／Ａ×100
Ａ：圧縮体の体積 Ｂ：圧縮後の体積
圧縮は型等に素材を収容し、プレス等により押
圧することにより容易に実施される。 Compression rate (%) = AB/A x 100 A: Volume of compressed body B: Volume after compression Compression is easily carried out by housing the material in a mold or the like and pressing it with a press or the like.
事実上記圧縮成形体を水中に投入すると急速に
膨張拡大し、同時に圧縮成形体の体積に対し200
ないし2500％の水分を吸収した。これに要する時
間はいずれの場合も90秒以内であつた。 In fact, when the above compression molded product is put into water, it rapidly expands and expands, and at the same time, the volume of the compression molded product is 200%
Absorbed up to 2500% of water. The time required for this was within 90 seconds in all cases.

水、膨張の効果が著るしく阻害され、本考案の目
的は達成されない。 The PVAt-based porous material applied to this invention is compressed in a substantially dry and hardened state, but if it has a high moisture content, that is, if it is compressed in a wet and softened state, it will recover as soon as the pressure is released. death,
A compression molded product cannot be obtained. In addition, if heat is applied during compression, a compression molded product can be obtained, but the deformation remains as a permanent strain, and even if it is placed in water, the water absorption and expansion effects are significantly inhibited, which is the purpose of this invention. is not achieved.
圧縮率と復元に要する時間はほゞ対応するが、
本考案に係るスポンジは小型である為、復元時間
は相対的に短くなり、圧縮率は30％以上であれば
十分である。 The compression rate and the time required for restoration are roughly related, but
Since the sponge according to the present invention is small, the restoration time is relatively short, and a compression ratio of 30% or more is sufficient.

It can be easily obtained by adding a pore-forming agent such as starch to this and reacting it with an aldehyde in the presence of a catalyst such as a mineral acid. Furthermore, if necessary, it is also possible to add colorants, fiber powder, fillers, etc., or to reinforce with fabrics, etc.
