Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises two containers stacked one on top of the other and a lid placed over the stacked containers, and the upper container is made of plastic. And a two-stage lunch box with a stainless steel lower container and lid,
The upper container, which is mainly used as a side dish, is covered with a sealed lid so that it can be stored in a slightly deeper lid when eating. Further, the present invention is characterized in that the above three members can be compactly stacked and stored after use. 2. Description of the Related Art Japanese Patent Application Laid-Open No. 9-154617 discloses a conventional two-stage lunch box in which upper and lower containers and a lid are made of aluminum. [0003] The above-mentioned aluminum lunch box of the prior application consists of three members, the upper and lower containers of a hermetically sealed two-stage lunch box, and the lid, which are mainly made of plastic. Therefore, the processing of each aluminum member is complicated, the cost is high, and the cleaning after use is difficult to achieve. In view of the above, the problem to be solved by the present invention is to provide a two-stage lunch box with upper and lower containers and a lid, by making the lower container and the lid stainless steel, thereby making this type of lunch box possible. The object is to make it more robust and durable, to make it easy to wash after use, to be convenient to use, and to be able to be stored compactly after use. [0004] In order to solve the above-mentioned problems, the present invention comprises two containers which are superimposed one on top of the other, and a lid which is covered on the superposed containers. A two-stage lunch box in which the upper container is made of plastic and the lower container and the lid are made of stainless steel, and the upper container is in a two-stage use condition on the outer periphery at an appropriate height away from the bottom. In addition to projecting a flange portion to be hooked on the upper edge of the lower container, a plastic sealing lid fitted to the upper edge of the container is provided separately from the lid, and the stainless steel lid is used. It has a depth to fit the upper part of the lower container stacked in two stages from the outer periphery, and after using the lunch box, the lower container emptied from above the upper container covered with the sealing lid. Put it upside down and turn the upper and lower containers The present invention provides a two-stage stainless steel lunch box, which is configured to be accommodated in the above-mentioned lid. In the lunch box of the present invention constructed as described above, the structures of the upper container made of plastic, the lower container made of stainless steel, and the lid are simplified, and the inner and outer peripheral surfaces can be formed to be smooth. In addition, durability is increased by making the lower container and the lid made of stainless steel. In addition, cleaning becomes easier than the conventional products. As shown in FIGS. 2 (a) and 2 (b), the lunch box of the present invention accommodates an upper container mainly used for serving a side dish in a lid which is opened and turned upright. By opening the sealed lid, the area for placing the lunch box on the table can be minimized, and the water droplets attached to the back of the sealed lid and the water droplets attached to the back of the bottom of the container are removed. It can be used conveniently without dripping. Further, after the use of the lunch box, as shown in FIG. 1 (b), the empty lower container is placed upside down from the upper container on which the sealing lid is fitted, and the lid is placed on its back. The two-stage lunch box can be stored compactly by storing it inside, which is extremely convenient for use. Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a lower container having a substantially rectangular overall shape, and 2 denotes a roughly rectangular shape.
A flange 3 is projected from an outer peripheral surface at an appropriate height away from the bottom, and the flange 3 is hung on the upper edge 4 of the lower container 1 to be superimposed and stacked. The sealing lid 6, which is fitted to and hermetically sealed by 2, is a lid formed slightly deeper so as to be covered from above the containers 1 and 2 stacked in two stages, as shown in FIG. . The lower container 1 and the lid 6 are both made of stainless steel, the upper container 2 is made of plastic, and the sealing lid 5 is made of plastic having flexibility. As shown in FIG. 1, the depth of the lid 6 is such that the outer periphery of the flange portion 3 and the outer periphery of the lower container 1 are fitted to the appropriate depth from the top of the containers 1 and 2 stacked in two stages in use. Having a depth to Further, the lower container 1 has a size in which the sealing lid 5 covering the upper container 2 is fitted from the outside, and is hooked on the flange portion 3. When the lunch box is constructed as described above, when the lunch box is used, as shown in FIGS. 2 (a) and 2 (b), the open lid 6 is placed on the back and placed beside the lower container 1, If the container 2 in the upper stage is used to be opened after the container 2 is inserted with the sealing lid 5 kept in it, a lunch box which does not take up much space can be used. In addition, it is possible to prevent drips generated from the upper container 2 mainly used as a side dish container and attached to the back surface of the sealing lid 5 from dropping out of the container. At the same time, it is possible to use such that water droplets mainly generated from the lower container 1 for storing rice and adhering to the bottom rear surface of the upper container 2 are not dropped outside. After using the lunch box as described above, FIG.
(B), when the upper container 2 in which the sealing lid 5 is fitted and the lower container 1 which is placed upside down on the upper container 2 are accommodated in the lid 6 turned up, Compact storage is possible. In use, the lunch box of the present invention is used in such a manner that it is carried around with a belt (not shown) tightened from outside. Further, in carrying out the present invention, the size and depth of the two containers 1 and 2, the formation position of the flange portion 3, the depth of the lid 6, and the like can be appropriately changed according to the gist of the present invention. Nor. The two-stage lunch box according to the present invention constructed as described above and used as described above is composed of two members 1 made of stainless steel together with a plastic upper container 2. 6, especially the shape of the lid 6 can be formed extremely simply, so that the cost can be reduced, and the cleaning after use is easy, and the hygienic management is easy. It can be stored compactly when not in use. When using a lunch box, it can save space and prevent water drops from falling around. In addition, it is extremely useful because it has high durability against shocks and high corrosion resistance.
