【０００８】
【発明の実施の形態】
以下図面について説明すると、１は、インサート成形により付設された模様２を頂板３の内面に有する透明の合成樹脂製蓋体で、頂板３外周から周壁を垂下し、かつ該周壁一部としての頂板左右両側壁4aの後部からは、下方に軸受孔５，５を有する軸受板６，６を垂下させている。
【０００９】
該蓋体は、図１から図３が示すように頂板３後面の左右方向中間下部ないし周壁一部としての後壁4bの上部にゲート跡７を有し、又その頂板は上面をフラットに、かつ内面は前後両部が低く、かつ中間部が高い弯曲面に形成している。又図３が示すように頂板３内面外周の隅部からは、下面開口の浅溝８を起立している。９は、頂板３下面へインサート成形により付設した模様２付きフィルムで、該フィルムの外周面が上記浅溝の内壁を形成している。該フィルムは転写フィルムでもよい。
【００１０】
上記蓋体１の形成は、図５が示すようにして形成する。
【００１１】
図５において11は固定形金型、12は可動型金型で、13は可動金型一部としてのコア金型である。固定金型11と可動金型12との分離面14において、固定金型側には蓋体の頂板形成用のキャビティ15が穿設してあり、又可動金型12側には、上記頂板外周から垂下させる周壁および軸受板６形成用の空所16が穿設されている。コア金型13上面外周へ開口させて、コア金型の下面および側面に沿ってバキューム通路17が穿設させてあり、コア金型13の上面と、上記周壁等形成用空所16内縁との間の可動金型部分上面が成形品の内壁形成面18をなし、該内壁形成面18外周からは、突条19を筒状に起立させ、該突条が囲む、上記内壁形成面18上へ、インサート成形用の模様付きフィルム９を載置させて、上記バキューム通路17によりそのフィルム９を吸着させているが蓋体頂板内面へ転写された後、シートだけを剥離するようにしてもよい。
【００１２】
19はゲートで、既述蓋体形成用キャビティ15後部の左右方向中間の可動金型分離面14に穿設させている。
【００１３】
図５が示す型締め状態において、上記キャビティ15および空所16内へ透明ないし半透明の溶融樹脂材料を射出することで、既述した、頂板内面に模様２を有する透明ないし半透明の蓋体１が形成されるから、金型を開いて成形品を取出せばよい。
【００１４】
上記溶融材料射出時において、内壁形成面18外周から筒状に起立する突条19は、該筒状の突条内へ嵌合された模様付きフィルム９が、ゲート20から射出された溶融樹脂材料によって位置ずれしたり、又ゲート側端部がめくれたりすることを防止し、頂板３内面へのインサート成形を確実にする。
【００１５】
尚図示例にあっては、上記筒状突条19を内壁形成面18の全周から起立させたが、ゲート20と対向する側、つまり図示例では内壁形成面18の右端にだけ設けてもよく、又ゲート側の内壁形成面側と対向する側の、内壁形成面外縁部分、つまり図示例では内壁形成面18の左端縁だけから起立させてもよい。前者の場合は上記フィルムのゲート側端面に対して、溶融樹脂材料が直接に射出されることでのフィルムの位置ずれ、又めくれを防止し、又後者の場合は溶融材料流れの下流側において、フィルムの端面を支持してその位置ずれを防ぐこととなる。又ゲート20を蓋体１の後面側に設けたが、側面ないし前面へ設けることも可能である。
【００１６】
上記実施形態では蓋体について説明したが、頂板外周から周壁等を垂下する台であっても同様に形成することが出来る。この場合は軸受孔５付きの軸受板６は省略することとなる。
【００１７】
【発明の効果】
本発明は、既述構成とするもので、各請求項記載の構成とすることで、透明ないし半透明の頂板３の内面に模様を有する蓋状体とすることが出来、その模様は頂板を透して見ることとなるため深みのある模様として見えることとなり、その装飾性を高めることが出来る。又その模様は頂板の内面に付設されているから、他物に直接触れることが少なく、そのため摩擦によりその模様が薄れたり、又剥離することがない。又浅溝８を設けたから、頂板３内面への模様付きフィルム９のインサート成形が容易となる。

[0008]
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, reference numeral 1 denotes a transparent synthetic resin lid body having a pattern 2 provided by insert molding on the inner surface of a top plate 3. The top plate hangs from the outer periphery of the top plate 3 and is part of the peripheral wall. Bearing plates 6 and 6 having bearing holes 5 and 5 below are suspended from the rear portions of the left and right side walls 4a.
[0009]
As shown in FIG. 1 to FIG. 3, the lid body has a gate mark 7 on the rear wall 4b as an intermediate lower part in the left-right direction or a part of the peripheral wall of the rear surface of the top plate 3, and the top plate has a flat upper surface. In addition, the inner surface is formed as a curved surface with both the front and rear portions being low and the middle portion being high. Further, as shown in FIG. 3, a shallow groove 8 with a lower surface opening is erected from the corner of the inner periphery of the top plate 3. 9 is a film with a pattern 2 attached to the lower surface of the top plate 3 by insert molding, and the outer peripheral surface of the film forms the inner wall of the shallow groove. The film may be a transfer film.
[0010]
The lid 1 is formed as shown in FIG.
[0011]
In FIG. 5, 11 is a fixed mold, 12 is a movable mold, and 13 is a core mold as a part of the movable mold. In the separation surface 14 between the fixed mold 11 and the movable mold 12, a cavity 15 for forming the top plate of the lid is formed on the fixed mold side, and the outer periphery of the top plate is formed on the movable mold 12 side. A peripheral wall to be suspended from and a space 16 for forming the bearing plate 6 are formed. The core mold 13 is opened to the outer periphery of the upper surface, and a vacuum passage 17 is formed along the lower surface and side surface of the core mold, and the upper surface of the core mold 13 and the inner edge of the space 16 for forming the peripheral wall, etc. The upper surface of the movable mold part in between forms the inner wall forming surface 18 of the molded product, and from the outer periphery of the inner wall forming surface 18, the ridges 19 are raised up in a cylindrical shape, and the ridges surround the inner wall forming surface 18 The film 9 with a pattern for insert molding is placed and the film 9 is adsorbed by the vacuum passage 17, but after being transferred to the inner surface of the lid top plate, only the sheet may be peeled off.
[0012]
Reference numeral 19 denotes a gate which is formed in the movable mold separating surface 14 in the middle in the left-right direction of the rear portion of the lid forming cavity 15 described above.
[0013]
In the mold clamping state shown in FIG. 5, the transparent or translucent lid having the pattern 2 on the inner surface of the top plate as described above is obtained by injecting a transparent or translucent molten resin material into the cavity 15 and the cavity 16. Since 1 is formed, the mold may be opened and the molded product taken out.
[0014]
At the time of the injection of the molten material, the protrusion 19 standing in a cylindrical shape from the outer periphery of the inner wall forming surface 18 is a molten resin material in which the patterned film 9 fitted into the cylindrical protrusion is injected from the gate 20 Prevents misalignment and turning of the gate side end, thereby ensuring insert molding on the inner surface of the top plate 3.
[0015]
In the illustrated example, the cylindrical ridge 19 is erected from the entire circumference of the inner wall forming surface 18, but may be provided only on the side facing the gate 20, that is, only the right end of the inner wall forming surface 18 in the illustrated example. Alternatively, it may be erected only from the outer edge portion of the inner wall forming surface on the side facing the inner wall forming surface side on the gate side, that is, the left edge of the inner wall forming surface 18 in the illustrated example. In the former case, the position of the film is prevented by direct injection of the molten resin material with respect to the gate side end surface of the film, and in the latter case, on the downstream side of the molten material flow, The end face of the film is supported to prevent the displacement. Further, although the gate 20 is provided on the rear surface side of the lid 1, it can be provided on the side surface or the front surface.
[0016]
Although the lid body has been described in the above embodiment, even a base that hangs a peripheral wall or the like from the outer periphery of the top plate can be similarly formed. In this case, the bearing plate 6 with the bearing hole 5 is omitted.
[0017]
【The invention's effect】
The present invention is configured as described above, and by configuring as described in each claim, a lid-like body having a pattern on the inner surface of the transparent or translucent top plate 3 can be formed. Since it will be seen through, it will appear as a deep pattern, and its decoration can be enhanced. Also, since the pattern is attached to the inner surface of the top plate, there is little direct contact with other objects, so that the pattern does not fade or peel off due to friction. Moreover, since the shallow groove 8 is provided, the insert molding of the patterned film 9 on the inner surface of the top plate 3 becomes easy.
