線押し等を経て組立られている。 Conventionally, this type of plastic case with a window was made by embossed drawing on one side of a plastic sheet, then die-cutting this into a case blank and simultaneously punching out a window, and then using a separately prepared transparent plastic for the window. It is pasted onto the window portion from the embossed diaphragm side using an ultrasonic seal or the like, and then assembled by stamping the lines or the like.
しかし、この従来の窓付きプラスチツクケース
においては、窓用透明プラスチツクの貼着周縁の
段部によりカセツトの挿脱が妨げられ、又、カセ
ツトに損傷を与えるなどの問題がある。 However, in this conventional plastic case with a window, there are problems such as a stepped portion on the periphery of the transparent plastic window that prevents insertion and removal of the cassette, and also causes damage to the cassette.
その他、窓部と梨地部をブロー成形により同時

スチツクが損傷を受け透明度が低下し易いなどの
問題があつた。 In addition, a plastic case with a window has been proposed in which the window and the matte part are formed at the same time by blow molding, but in this case, since the window part and the matte part are formed on the same plane, it is difficult to insert and remove the cassette. There were problems such as the relatively low hardness of the plastic forming the window being damaged by repeated use, resulting in a decrease in transparency.
この考案は上記事情に鑑みてなされたものであ
つて、カセツトのケースへの挿脱の繰り返しによ
つても窓部の透明性が損われるおそれのない窓付

である。 That is, this invention provides a plastic case with a window that is assembled from a single blank sheet with a transparent window formed in the plastic case body and a matte finish formed on the inner surface of the case body excluding the window.
The above window is 20 to 50 μm from the top of the uneven surface of the pear surface.
A plastic case with a window, characterized in that it is formed by forming a smooth recess having a depth of m and a depth greater than the distance from the top to the bottom of the uneven surface of the pear-skinned surface. It provides:
以下、この考案を図示の実施例を参照して説明

つて、上記熱可塑性シートの成形と同時にエンボ
スロール等によりシートの片面全体に形成させ
る。 In the figure, reference numeral 1 indicates a blank for a video cassette case, which is made of a transparent thermoplastic sheet having a thickness of 0.7 to 1.0 mm, such as transparent polypropylene. As shown in FIG. 2, a satin finish (tibbed pattern) 2 is formed on one side of the blank 1. As shown in FIG. This satin finish is necessary to improve feeder suitability during screen printing on blanks, or to improve slipperiness when inserting and removing cassettes after assembly into a case. At the same time as forming, it is formed on the entire one side of the sheet using an embossing roll or the like.
このように梨地２を形成したのち、裁断機を用

却を促進するようにしてもよい。 After forming the matte texture 2 in this manner, it is punched into a desired shape using a cutting machine to obtain a blank 1 as shown in FIG. Next, heat pressing is applied to the window-forming portion of the blank 1 on the side of the satin finish 2 with the abutting surface as a mirror surface, and the satin finish 2 in that portion is melted and solidified to be dissolved, thereby forming the mirror finish portion 3. As a result, the mirror surface portion 3 reproduces the original transparency of the transparent thermoplastic plank sheet, and a window 4 having a stepped portion depth of preferably 20 to 50 μm is formed. The hot press for forming this mirror surface part 3 may be one in which the abutting surface (or bottom) of the press mold is mirror finished, or a separate member 5 having a mirror surface is pasted on the bottom as shown in FIG. You may make it use the hot press 6 which attached. Further, in addition to the hot press 6, a cooling press (not shown) may be used in combination to accelerate cooling of the mirror surface portion 3.

窓付きケースが形成される。 Next, the portion of the blank 1 to be bent is subjected to a creasing process to form a bending line 7, and a blank 1 for automatic box making is obtained. Finally, this blank 1 is bent using an automatic box-forming device or the like so that the surface with the satin finish 2 becomes the inside of the case, and is mounted to form a case with a window.
なお、この窓付きケースへの印刷は上記いずれ

性が優れている。 According to this invention, as shown in FIG. 3, when a video cassette 9 is inserted into or removed from the assembled plastic case 8 with a window, the inner surface of the window 4 is formed below the bottom of the satin material 2 (as viewed from the inner surface of the window 4). This prevents the video cassette 9 from coming into contact with the inner surface of the window 4. Therefore, there is no risk that the window 4 will be damaged due to repeated insertion and removal of the video cassette 9, and the transparency of the window 4 will not be lost. It has good sliding properties and excellent feeder suitability.
なお、段部１０の角部は曲率半径２mm以上の曲
