本発明は弁当、折り箱等に使用される中仕切を
有する食品用容器の製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of manufacturing a food container having a partition for use in lunch boxes, folding boxes, and the like.
（従来の技術及び発明が解決しようとする問題

れている。(Prior Art and Problems to be Solved by the Invention) A typical conventional means of forming a food container with a partition using a foamed resin sheet is molding, as shown in FIGS. 4 to 6. There are some known types: those with a partition plate, and those with a separate inner container.
型成形によるものは、第４図に示すように発泡

り箱、弁当箱等としては使用できない。 As shown in Fig. 4, molding is performed by heating and softening the foamed resin sheet A, and vacuum-adsorbing the foamed resin sheet A into a mold, or pressing the sheet with a mold, so that the sheet A is divided into partitions corresponding to the mold. The container B is formed by forming the container into a container shape having an outer plate a and an outer plate b, and cutting off the remaining portion c of the outer periphery of the rear container edge. However, this container cannot be used as a folding box, lunch box, etc. because the outer plate b is necessarily inclined as it is necessary to remove the sheet from the mold.

を別製しなければならない不便がある。 Next, the one with the partition plate shown in Figure 5 is
The foamed resin sheet A was cut into a spread plate A' having an outer plate b' continuous to the four circumferences of the bottom plate, and the outer plate b' was bent and the adjacent ends were heat welded to form a container B'. rear,
A partition plate C is separately formed and placed inside the container B'. However, this container only has partitions, and if you put soup in one partition, it will flow to the other partition, so it is not suitable as a partition container for folding boxes or lunch boxes, and there is also a partition inside. There is the inconvenience of having to manufacture it separately.

が、外側板部分と中容器を別々に形成しなければ
ならない煩雑さ及び更に両者を組み合わせなけれ
ばならない煩雑さがある。 In addition, in the case of the inner container shown in Fig. 6, the framework D of the outer plate is formed from a foamed resin sheet, the container E with partitions is formed separately from a thin resin plate, and the two containers are combined. Container B" with an inner partition is formed (see Utility Model Application Publication No. 58-70371). This container is ideal for lunch boxes, folding boxes, etc., but the outer plate part and the inner container are formed separately. There is the complexity of having to do both, and the complexity of having to combine both.

ある。(Means for Solving the Problems) In view of the above-mentioned problems, the present invention proposes a method for easily forming a food container having a partition. That is, the method for producing a container according to the present invention involves forming partition ridges on a foamed resin sheet or other thermoplastic resin sheet by molding, and then cutting the sheet into a spread plate having a container outer plate disposed on the outer periphery. , the container is formed by bending the outer plate and heat welding adjacent parts of the outer plate to each other.
従つて外見は従来の展開板によるものと同様に

連続状態となるものである。 To explain the first embodiment shown in FIG.
The foamed resin sheet 1 is formed by molding to form the partition protrusions 2 on the corresponding part of the bottom plate of the container to be formed, and then cutting and forming the expansion plate 1a on which the corresponding part of the outer plate 3 around the bottom plate is arranged. do. The container 5 is formed by raising the rear outer plate 3 and heat-welding the edges 4 of the outer plate 3 to each other. If the notch 6 is made in the middle partition protrusion 2, after the outer plate 3 is raised up, the protrusion part on the outer plate side will be pushed into the other protrusion part, and the side plate and the inner partition will be continuous. It is a state.

である。 Next, in a second embodiment shown in FIG. 2, a container part 7 is formed on a foamed resin sheet 1 along with a partition ridge 2' by molding in the same manner as in conventional molded containers, and the container part 7 is formed on the foamed resin sheet 1 by molding. When the peripheral portion of the container portion 7 is cut so that the outer plate portion 8 remains on the outer periphery of the edge, the attached plate portion 8 is bent, and the edges of the plate portion 8 are heat welded.
A container 5' is formed in which the plate portion 8 serves as an outer plate.

Furthermore, a non-foamed resin sheet may be used instead of the foamed resin sheet.
