58−18735号に示された構造のものがその意味で
は優れているといえる。(Problems to be solved with the invention) Depending on the purpose of the container, it may be functionally advantageous to have an inner plate.
It can be said that the structure shown in No. 58-18735 is superior in that sense.

ところが、上記の容器においては上蓋を開被し
た際、これに関連して中皿が上昇するものの、そ
の上昇の程度は比較的小さいところから中皿と下

であるという難点があつた。 However, in the above container, when the top lid is opened, the middle plate rises, but the degree of rise is relatively small, and the distance between the middle plate and the bottom plate is small, and the contents are There was a drawback that it was inconvenient to take out.

そのために本考案者らは最近第５図に示した構
造の容器を開発するに至つた。 For this reason, the inventors of the present invention have recently developed a container having the structure shown in FIG.

沿つて移動自在に嵌装して構成したものである。 The container shown in FIG. 5 has a lower plate 1 and an upper lid 2 that can be opened and closed on one side by a hinge mechanism, and an inner plate 3 that can be moved in and out of the lower plate 1 as the upper lid 2 is opened and closed. , between the middle plate 3 and the lower plate 1 that go in and out of the lower plate 1, the left and right outer end surfaces of the middle plate 3 and the left and right inner end surfaces of the lower plate 1 are parallel to each other with a constant distance between them. A pair of supporting bars 4a and 4b are rotatably fixed to the middle plate 3 and the lower plate 1 at both ends thereof in the longitudinal direction through fixing shafts 5, 5 and 6, 6, and The back end of the left and right end surfaces of the tray has a connecting projection 7 that projects in the longitudinal direction of the inner plate, and the connecting projection 7 is provided in the left and right end surfaces of the upper lid 2 in the longitudinal direction. It is configured to be fitted into the groove 2a so as to be movable along the groove.

欠陥品として排斥されて製品歩留り率を低下させ
る原因となつた。 However, in the case of such a structure, firstly, when the upper lid 2 is closed and the inner tray 3 is inserted into the lower tray 1, one of the support bars 4b interferes with the other support bar 4a, and especially the support bar 4b The fixing shaft 5 of the support bar 4a often comes into contact with the approximate middle part of the other support bar 4a and prevents the inner plate from completely entering the lower plate 1, resulting in the product being rejected as a defective product and reducing the product yield rate. This was the cause of the decline.

ことを特徴とするものである。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention particularly improves the ability to store the inner tray in the lower tray, improves the product yield rate, and improves the connection of the inner tray to the upper lid. It is designed to prevent damage to the protruding parts and improve durability. Specifically, it has a lower plate and an upper lid that can be opened and closed on one side using a hinge mechanism, and a lower plate that is inserted into the lower plate via a link mechanism. In a container having an inner plate that is placed in the container and floats up from the lower plate when the upper lid is opened, the link mechanism is configured to maintain a constant distance between the left and right outer end surfaces of the inner plate and the left and right inner end surfaces of the lower plate. It consists of a pair of support bars whose both ends are rotatably fixed through the support bars, and each of the pair of support bars is characterized in that substantially middle portions of the support bars are bent in a direction in which they are separated from each other. be.

る。 The lower plate 11 and the upper lid are configured so that they can be opened and closed on one side by a hinge mechanism, and the lower plate 11
A locking portion 19 protruding outward is formed at a position closer to the center opening on the front side of the top lid 12, and a locking portion 19 protruding inwardly is formed at a position closer to the center opening on the front side of the top lid 12 in correspondence with the locking portion 19. A recessed locking portion 18 is formed in the upper lid 12, and grooves 12a are formed on both left and right sides of the upper lid 12.
is formed to protrude outward by embossing.

3 and the left and right inner end surfaces of the lower plate 11, a pair of screws are rotatably fixed at both ends by fixing shafts 15, 15 and 16, 16, respectively, with a fixed interval between them. It consists of support bars 14a and 14b, and the pair of support bars 14
Both a and 14b are formed by bending their substantially intermediate portions in a substantially dogleg shape in the direction of separating them from each other, with their recessed surfaces facing each other.

せて取りつけられている。 Furthermore, the inner plate 13 has a connecting protrusion 17 that projects in the longitudinal direction on the left and right end surfaces of the inner plate 13 at the end closer to the dorsal side, and this can be slid freely into the above-mentioned groove 12a of the upper lid 12. This allows the inner plate 13 to move in and out of the lower plate 11 as the upper cover 12 is opened and closed, and also connects the bottom of the center part of the inner plate 13 near the front and the back end flange of the lower plate 11. A contraction coil spring 20 is attached between the two and always biased in the contraction direction.

る。(Function) In the configuration of the embodiment described above, when the upper lid 12 is opened, the inner tray 13 rises from the opening of the lower tray 11, opening the lower tray 11 wide (see FIGS. 1 and 2). (see figure), as well as the upper lid 12.
As the inner tray 13 is closed, the inner tray 13 enters and is stored in the lower tray 11 (see FIGS. 3 and 4), and the locking parts 18 and 19 engage with each other to close the lid. .

As a result, the interlocking protrusion does not come off in a relatively short period of time, and as a result, durability can be significantly improved. Further, by interposing a spring between the inner tray and the lower tray, the upper lid can be opened and closed more easily, and the operability can be further improved.
