〔産業上の利用分野〕
本発明は、合成樹脂製成形品の表面に独特の模様を有す
る合成樹脂製中空成形品の製法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a synthetic resin hollow molded article having a unique pattern on the surface thereof.
（従来の技術）
合成樹脂製の中空成形によってつくられる化粧品の容器
、楽器ケース、或いは自動車のアームレストやグローボ
ックスの蓋等は、外観を美しくする必要がある。そのた
め、従来金型にシボ加工を施し、中空成形する際に、上
記シボを製品に転写するなどの方法が行なわれている。(Prior Art) Cosmetic containers, musical instrument cases, automobile armrests, glow box lids, and the like, which are made by hollow molding of synthetic resin, need to have a beautiful appearance. Therefore, a conventional method has been used in which a mold is textured and the texture is transferred to the product during blow molding.
しかし、中空成形の場合、低圧な空気によって金型内面
に溶融したりパリソンを押付けるので、製品の肉厚の差
、ブローの差、または金型内面のエアー抜きの状態など
により、シボ形状が明瞭に現われる部分と現われない部
とがあり、シボ状態にむらを生ずる欠点があった。However, in the case of blow molding, low-pressure air melts or presses the parison against the inner surface of the mold, so the grain shape may vary due to differences in product wall thickness, blowing, or air release conditions on the inside of the mold. There are parts where the grain appears clearly and parts where it does not appear, resulting in an uneven texture.
本発明は上記の事情に鑑み、合成樹脂製中空成形品の表
面にむらのない独特の模様を形成し外観の優れた中空成
形品の製法を提供することを目的とする。In view of the above circumstances, an object of the present invention is to provide a method for producing a synthetic resin hollow molded product with an excellent appearance by forming a uniform and unique pattern on its surface.
本発明は、上記の目的を達成するためになされたもので
、その要旨は、ダイスから溶融押出した合成樹脂製パリ
ソンと、型開きした金型との間の少なくとも一方に解繊
ウェブを配置し、型締を行なう過程、或いはエアーブロ
ーしてパリソンを膨張させる過程において、該パリソン
の表面に上記解繊ウェブの模様を付与する模様付合成樹
脂製中空成形品の製法にある。The present invention has been made to achieve the above object, and its gist is that a defibrated web is placed between at least one of a synthetic resin parison melt-extruded from a die and an opened mold. , a method for producing a patterned synthetic resin hollow molded article, in which the pattern of the defibrated web is imparted to the surface of the parison during the mold clamping process or the process of expanding the parison by air blowing.
以下、本発明を図面を参照して説明する。 Hereinafter, the present invention will be explained with reference to the drawings.
第１図ないし第３図は、本発明の方法を実施する装置の
一例を示すもので、第１図は装置の縦断面図である。1 to 3 show an example of an apparatus for carrying out the method of the present invention, and FIG. 1 is a longitudinal sectional view of the apparatus.
図中符＠１はダイスである。ダイス１からは、溶融した
円筒状のパリソン２が型間さした金型３゜３の間に押出
される。また、上記金型３，３とパリソン２との間には
、ロール４・・・によって送られた＠ｊｕウェブ５がそ
れぞれ配置されている。The mark @1 in the figure is a die. From the die 1, a molten cylindrical parison 2 is extruded between two molds 3.3. Moreover, between the molds 3, 3 and the parison 2, @ju webs 5 sent by rolls 4, . . . are arranged, respectively.
次いで上記金型３．３を型締すると第２図に示すように
、パリソン２および解繊ウェブ５は金型３．３に挾持さ
れる。この際、金型４，４の解繊ウェブ５は、全面的に
パリソン２に接し、その保有する熱市によって昇渇し流
動状態となる。しかし、一部接触しない部分があっても
ノズル６よりエアーブｎ −−ｄることによりパリソン
３は膨張し、その過程において解繊ウェブ全体がパリソ
ン３に接し流動性となる。さらに、エアーブローを行な
うと、第３図に示すようにパリソン３はキャビティーぽ
いに広がり、上記流動性の解繊ウェブ５は、金型内面に
押圧され、パリソン外面に一体に畜骨する。これを冷却
、固化して金型３，３を聞けば、表面に解繊ウェブによ
る独特の模様がつけられた中空成形品が１ｑられる。Then, when the mold 3.3 is clamped, the parison 2 and the defibrated web 5 are clamped in the mold 3.3, as shown in FIG. At this time, the defibrated webs 5 of the molds 4, 4 are entirely in contact with the parison 2, and are elevated and depleted by the heat market held by the parison 2, and become fluid. However, even if some portions do not come into contact with each other, the parison 3 is expanded by air blowing from the nozzle 6, and in this process, the entire defibrated web comes into contact with the parison 3 and becomes fluid. Further, when air blowing is carried out, the parison 3 expands to form a cavity as shown in FIG. 3, and the fluid defibrated web 5 is pressed against the inner surface of the mold and is integrally attached to the outer surface of the parison. When this is cooled and solidified and molded into molds 3 and 3, 1q of hollow molded products with a unique pattern created by the defibrated web on the surface are obtained.
上記の説明のようにｌｉｔウェブ５は、パリソンの保有
する熱によって昇温され流動化するので、解繊ウェブ５
の材質としては、流動化温度がパリソンと同等、或いは
これより低いことが必要である。特に中空成形品の肉厚
が薄いものを要求される場合には、パリソンの肉厚も薄
いものが用いられ、その保有する熱１も少ないため、パ
リソンの材質に比して相当低い流動化温度の解繊・クエ
ブを使用しなければならない。As explained above, the lit web 5 is heated and fluidized by the heat held by the parison, so the fibrillated web 5
The material must have a fluidization temperature equal to or lower than that of the parison. In particular, when a thin-walled blow molded product is required, a thin parison is used, and because it retains less heat, the fluidization temperature is considerably lower than the material of the parison. Defibration/queve must be used.
また、解ｆｕウェブの配置をパリソンと金型との一方の
間のみとすることにより、片面のみに模様を付与するこ
とも出来る。Furthermore, by arranging the fu-fu web only between one side of the parison and the mold, it is possible to impart a pattern to only one side.
（実施例）
次に種々な材料のパリソン用樹脂および解繊ウェブを組

ト状のものを用いた。(Example) Next, parison resins made of various materials and defibrated webs were combined, and a 120 x 200 x 2
A hollow molded product with a pattern on the surface was made as a prototype with a thickness of 5 tta, an average wall thickness of 2.0 m, and a weight of 120 g. The defibrated web is
A sheet-like single fiber having a denier of 10 to 1 oOo and 300/Td was used.
各材料の組合わせを第１表に示す。Table 1 shows the combination of each material.

ぼむらが生ぜず、金型に対するしぼ加工が不要となるの
で金型コストが安くなる。Table 1 As a result, in each case, a hollow molded product with a uniform and beautiful pattern was produced. A pattern can be imparted to the entire surface, uneven wrinkles do not occur due to molding conditions, and there is no need for graining on the mold, resulting in lower mold costs.
さらに、使用する解繊ウェブの目の荒さ、或いは単繊維

の長所を有し、今後各方面に広い需要が期待される。Furthermore, the pattern can be changed by appropriately selecting the coarseness of the fibrillated web used or the thickness of the single fibers.
In addition, by changing the colors of the parison and JMr. Quaeb, the contrast between them becomes clearer, the pattern becomes clearer, and products with different visual sensations can be obtained. There is expected.
