Therefore, in this invention, the opening angle of the lid is restricted so that the container will not lose its balance and fall due to the weight of the lid even when there are few things stored in the container body. The challenge is to provide. [Structure] One side of a lid 2 is rotatably attached to a container body 1 to form a vertically split structure, and a rear portion of a middle plate 3 is attached to a support rod 2b extending from the inside of the lid 2. An open / close container with a middle plate, which is rotatably locked, and in which the middle plate 3 is moved back and forth according to the opening / closing movement of the lid body 2, provided with an engagement protrusion 3b on the lower surface of the middle plate 3, When the lid 2 is opened to a predetermined angle,
The engaging projections 3b hit the upper edge 1a of the peripheral wall of the container body 1 to limit the opening angle of the lid 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an open / close container with a middle plate used for storing fishing tackle, sewing tools, household medicine, tools and the like.

[0002]

[Prior art]

 Conventionally, the open / close container with the inner plate has a structure in which one side of the lid is pivotally attached to the container body so that the upper and lower parts are split and the inner plate moves back and forth according to the opening / closing movement of the lid. It was from The middle plate of this container had a rear portion rotatably connected to a support rod extending from the inside of the lid. Then, when the lid was opened, the rear part of the inner plate was pulled by the lid and moved backward.

However, this conventional container has a problem in that if the container body is small and the lid is opened, the container loses its balance due to the weight of the lid and tends to fall.

[0004]

[Problems to be solved by the device]

 Therefore, this invention was made in order to solve the above-mentioned conventional problems.By limiting the opening angle of the lid, even if there are few things stored in the container body, the container is balanced by the weight of the lid. The task is to provide an open / close container with a middle plate that does not lose and fall.

[0005]

[Means for Solving the Problems]

 Therefore, in this invention, one side of the lid body 2 is rotatably attached to the container body 1 so as to have an upper and lower split structure, and a supporting rod 2b extending from the inside of the lid body 2 has an inner plate. An opening / closing container with a middle plate, in which the rear part of the third plate 3 is rotatably locked so that the middle plate 3 can move back and forth according to the opening / closing movement of the lid body 2. 3b is provided, and when the lid 2 is opened to a predetermined angle, the engaging projection 3b hits the upper edge 1a of the peripheral wall of the container body 1 to limit the opening angle of the lid 2.

[0006]

[Action]

 In the open / close container with the inner plate having the above structure, when the lid 2 is opened, the rear portion of the inner plate 3 is pulled by the support rod 2b, so that the inner plate 3 moves rearward. When the lid 2 is opened to a predetermined angle, the engaging protrusion 3b provided on the lower surface of the inner plate 3 comes into contact with the upper edge 1a of the peripheral wall of the container body 1. Therefore, the lid body 2 cannot be opened any more, and the amount of movement of the center of gravity of the lid body 2 to the rear is reduced, so that the container can be kept in a stable state.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state in which the lid of the open / close container with a medium tray of the present invention is opened.

Reference numeral 1 denotes a plastic container body, the upper part of which is open, and the front, rear, left and right sides are surrounded by peripheral walls.

Reference numeral 2 denotes a plastic lid body, the lower part of which is open and the front, rear, left and right sides are surrounded by peripheral walls. Further, a frame body 2a is formed inside the lid body 2, and the upper end 3a of the inner tray 3 is just inside the frame body 2a when the lid body 2 is closed. Further, on the right and left sides of the frame body 2a, support rods 2b for rotatably locking the rear portion of the inner plate 3 are formed.

The inner plate 3 is a plastic plate having a partition, and an engaging protrusion 3b is provided on the lower surface thereof. Further, one end of each of the left and right front portions of the inner tray 3 is connected by a link rod 4 rotatably attached to the container body 1.

An L-shaped engaging protrusion 4 a having a tip extending inside the container body 1 is provided at substantially the center of the link rod 4. The L-shaped engagement projection 4a abuts the lower surface of the inner tray 3 when the lid 2 is closed, and plays a role of supporting the inner tray 3.

Reference numeral 5 is a buckle that locks the lid 2 so that the lid 2 does not open when the lid 2 is closed. (See FIG. 2) The above is a description of each component, and next, the state when the lid 2 of the container of the present invention is opened and when it is closed will be described.

FIG. 3 is a cross-sectional view showing a state in which the lid body 2 is closed. As shown, the front portion of the inner plate 3 is supported by the link rods 4, and the rear portion of the inner plate 3 is the lid member 2. It is in a state of being suspended by the support rod 2b of.

When the lid 2 is rotated so as to be opened, the rear portion of the inner plate 3 is pulled backward by the support rod 2b of the lid 2. At this time, since the front portion is locked to the link rod 4, the inner tray 3 moves rearward in parallel.

When the lid body 2 is opened to a predetermined angle, the engagement protrusion 3b provided on the lower surface of the inner plate 3 comes into contact with the upper edge 1a of the peripheral wall of the container body 1. Then, since the inner plate 3 cannot move further backward, the vertical lid 2 cannot be opened any more. (See FIG. 4) The above is the embodiment, and the position at which the engagement protrusion 3b is provided may be arbitrarily set according to the opening angle set by the lid 2.

[0017]

[Effect of device]

 The open / close container with the inner plate of the present invention is configured as described above, and when the lid 2 is opened to a predetermined angle, the engaging protrusion 3b provided on the lower surface of the inner plate 3 causes the upper edge of the peripheral wall of the container main body 1 to move. Since it hits 1a, the opening angle of the lid body 2 is limited and it cannot be opened any more. Therefore, even when the lid body 2 is opened, the amount of movement of the center of gravity of the lid body 2 to the rear is small, and the container maintains a stable state in which the weight of the lid body 2 does not cause the balance to fall and fall. It becomes a convenient container.
