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. For a two-stage lunch box with a lower container and a lid made of aluminum, the upper container mainly used as a side dish is covered with a sealed lid, and stored in a slightly deeper lid for meals It can be so. Further, the present invention is characterized in that the three members are compactly overlapped after use. 2. Description of the Related Art A conventional two-stage lunch box having an aluminum container and a lid is disclosed in, for example, Japanese Patent Application Laid-Open No. 9-1.
No. 54617 is known. [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. Accordingly, the problem to be solved by the present invention is to simplify the structure of a two-stage lunch box having upper and lower containers and a lid, and the lower container and the lid made of aluminum so that they can be manufactured at low cost. Along with
An object of the present invention is to make it easy to wash after use, convenient to use, and compact 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. In a two-stage lunch box where the upper container is made of plastic and the lower container and the lid are made of aluminum, the upper container is placed on the outer periphery at an appropriate height from the bottom, and the lower container is A flange portion to be hooked on an upper edge of the container is protruded, and separately from the lid, a sealing lid fitted to the upper edge of the container is provided. With a depth to fit the upper part of the container from the outer circumference, after using the lunch box, cover the lower container emptied from above the upper container covered with the sealing lid upside down,
The present invention provides an aluminum two-stage bento box characterized in that the upper and lower containers are configured to be accommodated in the lid turned upside down. In the lunch box of the present invention constructed as described above, the structure of the plastic upper container and the structure of the aluminum lower container and lid are both simplified, and the inner and outer peripheral surfaces can be formed to be smooth surfaces. Therefore, the cost can be reduced and the cleaning becomes easy. Then, FIG.
As shown in (b), if the upper container mainly used for serving a side dish is accommodated in a lid which is opened and turned upside down, and the sealing lid previously covered on the container is opened, The area where the lunch box is placed on the table can be minimized, and the water drop on the back surface of the sealing lid and the water drop on the bottom back surface of the container can be conveniently used so as not to be dropped outside. 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 seals the container 2, is a lid which covers the containers 1 and 2 which are stacked in two stages, as shown in FIG. The lower container 1 and the lid 6 are both made of aluminum, 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 6 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 upper container 2 is inserted into the container 2 and then opened while the sealing lid 5 is kept therein, it is possible to use a lunch box which does not take up much space. 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 aluminum members 1 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 is very useful because it takes up little space and can prevent water drops from falling around.
