本発明は熱可塑性合成樹脂から成形された円筒
容器の表面に所望の模様を絵付けする方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for painting a desired pattern on the surface of a cylindrical container molded from a thermoplastic synthetic resin.

透明模様を浮出させている。 Conventionally, transparent patterns have been painted on the surface of synthetic resin cylindrical containers with a matte finish that looks like frosted glass. A so-called masking cover cut out in a predetermined pattern is adhered to the surface of a transparent synthetic resin container, then this container is sandblasted to give it a satin finish except for the areas covered with the masking cover, and finally the masking cover is removed. The transparent pattern stands out.

ものであつた。 However, in the above painting method, a masking cover is applied to the surface of the container, so if the painting pattern is not a continuous pattern, it is difficult and troublesome to apply the masking cover accurately at the predetermined position. The work was inefficient and unsuitable for automation.

ある。 The present invention was made in view of the above-mentioned deficiencies in the conventional painting method, and its purpose is to eliminate the need for a masking cover and to paint a part of the surface of a cylindrical container made of thermoplastic synthetic resin with a satin finish. To provide a novel painting method which can extremely easily reveal a transparent pattern, has excellent workability, and is suitable for automation.

ことにより透明化してなるのである。 That is, in the painting method of the present invention, a predetermined pattern is embossed on the circumferential surface, and the surface of the embossed pattern is smoothed between the heating roller and the holding roller. A cylindrical container made of a thermoplastic synthetic resin is held and rotated, and the embossed pattern portion of the heating roller is heated by a heating element disposed close to the circumferential surface of the heating roller. The surface of the container is made transparent by melting a portion of the surface of the container corresponding to the embossed pattern of the heating roller.

容器５に圧接されるように調整されている。 The device used to carry out the method of the invention consists of a silicone roller 1 , a heating element 2 and a holding roller 3 . The silicon roller 1 has an embossed pattern portion 4 formed on its circumferential surface corresponding to the painted pattern, and the surface of the embossed pattern portion 4 is formed as a smooth surface. heating element 2
is for heating the embossed pattern portion 4, and is provided on a portion of the circumferential surface of the silicon roller 1. The holding roller 3 is for rotating the cylindrical container 5 made of thermoplastic synthetic resin while holding it between the holding roller 3 and the silicone roller 1. Preferably, a heat-resistant smooth film 6, such as a polyethylene terephthalate film, is interposed between the silicone roller 1 and the cylindrical container 5 to be painted, and is fed out as the film rotates. Also,
The interval between the silicone roller 1 and the holding roller 3 is such that when the cylindrical container 5 is sandwiched between them and rotated, only the embossed pattern portion 4 of the silicone roller 1 is held in the cylinder via the film 6. It is adjusted so that it is pressed into contact with the container 5.

でなく金属製ローラーも利用できる。 The entire outer circumferential surface of the cylindrical container 5 used in the present invention is finely roughened with a satin finish, and the cylindrical container 5 with the satin finish is placed between the holding roller 3 and the silicone roller 1. When the heat-resistant film 6 is interposed between the cylindrical container 5 and the silicone roller 1 and these rollers 1 and 3 are rotated, only the embossed pattern portion 4 of the silicone roller 1 comes into contact with the cylindrical container 5 through the film 6. contact, thereby melting the part 7 of the cylindrical container 5 to the relief pattern 4. At this time, since the heat-resistant film 6 is interposed, the surface of the melted part of the cylindrical container 5 becomes smooth and transparent, so that the transparent pattern 7 stands out on the cylindrical container 5, which has a satin finish. It is painted. In addition, since the surface of the embossed pattern portion 4 on the silicon roller 1 is formed as a smooth surface,
In the present invention, it is possible to obtain a transparent melted pattern 7 on the cylindrical container 5 without using the heat-resistant film 6, but preferably by using this film 6, an even more beautiful transparent part can be obtained. It is. Although a silicon roller was used as the heating roller in the above embodiment, the heating roller is not limited thereto, and a metal roller may also be used.

能率が優れ自動化に適した方法である。 As is clear from the above description, the painting method of the present invention eliminates the conventional troublesome work of attaching a masking cover before sandblasting and removing it afterwards, and also enables the painting of a predetermined pattern. A cylindrical container 5 made of a thermoplastic synthetic resin is sandwiched between a heating roller 1 and a holding roller 3, which are formed in relief on the circumferential surface, and rotated in a single step, whereby the surface is very easily made into a pear-like texture. Since a transparent pattern 7 corresponding to the embossed pattern 4 of the heating roller can be obtained on the surface of the cylindrical container, this method has excellent work efficiency and is suitable for automation.
