を得る構成を特徴とするものである。For this purpose, the present invention has a downwardly directed edge on the outside of the rising peripheral edge of the inner cylindrical plate, and has an L-shaped portion on the inner peripheral side of the lower end of this edge, and also has an L-shaped portion on the inner peripheral side of the lower end of this edge. In between, an inner casing with a lip and an outer casing with a downwardly diagonal protrusion on the outside of the rising edge of the outer cylindrical plate are molded separately from synthetic resin, and then the inner casing is molded. With the edge forming part and the upper edge of the outer casing engaged, this retaining part is integrally heat-sealed to form a double hollow cylinder structure of the inner and outer casings, and then, A bento container is obtained by integrally molding a band of synthetic resin material from the lower edge of the inner casing to the entire outer periphery of the outer casing by fusion with the diagonal protrusions. It is.
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.

発明方法は、先ず好ましくはＡ、Ｂ、Ｓ樹脂等の合成樹
脂材をもって内側筐体１と外側筺体１ｏをそれぞれ別体
に成形する。Fig. 1 is a plan view of an example of a bento container obtained by the present invention, Fig. 2 is a sectional view taken along the line ■-■, and Figs. 3 to 6 are partially omitted to show the manufacturing process. In the method of the present invention, first, the inner casing 1 and the outer casing 1o are separately molded using synthetic resin materials such as A, B, and S resins.
内側筐体１は第３図に示すように、内側筒板２の立ち上
がり周縁［３の外側に下向き縁部４を有すると共に、こ
の縁部４の内側にはＬ形設部５を有し、また周縁部３と
縁部４との間には適宜の間隔で、下端外側に縁部４の段
部５と連らなるＬ形設部７を設けたリプ６を有する。As shown in FIG. 3, the inner housing 1 has a downwardly directed edge 4 on the outside of the rising edge [3] of the inner cylindrical plate 2, and has an L-shaped portion 5 on the inside of this edge 4. Further, between the peripheral portion 3 and the edge portion 4, there is provided a lip 6 having an L-shaped portion 7 connected to the stepped portion 5 of the edge portion 4 on the outer side of the lower end at an appropriate interval.
このリプ６は後述する外側筐体１ｏおよび帯状部の成形
時に内側筺体１の立ち上がり周縁部３と下向き縁部４と
の間隔を一定に保持し、また外側筐体１０との間隔を一
定に保持すべく機能するものである。This lip 6 maintains a constant distance between the rising peripheral edge 3 and the downward edge 4 of the inner casing 1 during molding of the outer casing 1o and the band-shaped portion described later, and also maintains the distance between the outer casing 10 and the outer casing 10. It functions as it should.
外側筺体１０は第４図に示すように、外側筒板１１の立
ち上がり周縁部１２の外側圧下向き斜向状突起１３を有

までの外周部１４は円弧の段差状を呈し、さらに外側筺
板平担部との境にはＬ形設部１５を有する。As shown in FIG. 4, the outer casing 10 has an oblique protrusion 13 facing outward downward on the rising peripheral edge 12 of the outer cylindrical plate 11, and from the lower end of this protrusion 13 to the flat part of the outer electric plate 11. The outer peripheral portion 14 has an arcuate stepped shape, and further has an L-shaped portion 15 at the border with the flat portion of the outer housing plate.
なお、内側筒１＋１は第１図および第２図に示すいくつ
もの副食筒部８を有する形状に限定されないことは勿論
であり、内側筒板２の立ち上がり周縁部３の外側に下向
き縁部４を有し、この縁部４の内側にはＬ形設部５を有
し、さらに周縁部３と縁部４との間にリプ６をそれぞれ
一部に有する構成であれば、内側筒板２の形状は任意で
ある。It should be noted that the inner cylinder 1+1 is of course not limited to the shape having a number of auxiliary cylinder parts 8 as shown in FIGS. 1 and 2. If the inner cylindrical plate 2 has an L-shaped portion 5 on the inside of the edge 4, and a lip 6 is partially provided between the peripheral edge 3 and the edge 4, The shape is arbitrary.
側筺捧１の縁部り形設部５とリプ６のＬ形設部７に外側
筐体１０の立ち上がり周縁部１２の上端を係合せしめた
状態において両者の保合都を、型を締め加熱して一不的
に熱融着する。With the upper end of the rising peripheral edge 12 of the outer casing 10 engaged with the edge forming part 5 of the side casing 1 and the L forming part 7 of the lip 6, the mold is tightened to hold the two together. Heat to permanently fuse.
この場合において、内側筒ｉ＋１の立ち上がり周縁３と
縁部４の間隔はリプ６によって保持されているため、成
形時に周線３と縁部４との間が圧潰されるということは
ない。In this case, since the distance between the rising peripheral edge 3 and the edge 4 of the inner cylinder i+1 is maintained by the lip 6, the space between the peripheral line 3 and the edge 4 will not be crushed during molding.
このようにして、内外筺体１．１０を成形し、二重中空
筒構成となし、次いで、第６図に示すように、内側筺体

第２図に例示する弁当容器を得る。In this way, the inner and outer casings 1.10 are formed into a double hollow tube configuration, and then, as shown in FIG. Installation part 1
A band 2° of synthetic resin material is integrally molded over the outer peripheral edge metal bar of up to 5 rising edges to obtain the lunch container illustrated in FIGS. 1 and 2.
この場合において、内外側筐ｆ＋１．１０はその接合部

される。In this case, the inner and outer casings f+1.10 are partially heat-sealed at their joints, and lips 6 are provided at appropriate intervals.
Since the distance between the inner and outer antistatic 11+1.100 is maintained by
Moreover, due to the synergistic effect of the bath melting of the diagonal protrusion 13 portion of the outer casing 10 and the arcuate stepped portion of the outer peripheral portion 140, the inner and outer casings 1.10 and the strip portion 20 are The material is extremely strong and partially glued.
なお、蓋体については公知の成形手段にして、かつ公知
いずれの構造のものでもよいため、図示および説明は省
略する。Note that the lid may be formed using any known molding means and may have any known structure, so illustrations and descriptions thereof will be omitted.
しかして、本発明によれば、成形時において内外側筐体
