The outer peripheral edge of the lid 2 is one size wider than the outer peripheral edge of the main body 3, and is aligned with the outer peripheral edge of the flange portion 12 protruding outward from the main body 3. The vicinity of the outer periphery of the lid 2 is curved so that the thick surface 28 of the edge portion thereof faces downward, and the thick surface 28 of the outer peripheral edge abuts on the collar portion 12 to form the lid 2. The main body 3 is closed.

The thickness surface 28 of the outer peripheral edge of the lid 2 has a packing groove formed over the entire circumference and recessed upward, and a packing fitted in the groove, so that the inside of the container can be sealed. .. The packing is, for example, a loop-shaped tube made of rubber or silicon.

As shown in FIG. 6, on the front side and the rear side of the surface of the lid body 2, the portions of the gripping opening / closing bodies 4 and 4 to be attached in the locked state, which will be described later, are surrounded by a substantially U-shape. The raised portions 21, 21 are formed. The surface of the lid 2 has an outer portion in the front-rear direction surrounded by the raised portions 21 and 21 (a portion on which the gripping opening / closing bodies 4 and 4 are arranged and a portion surrounded by the raised portions 21 and 21) more than the other portions. Recesses 27, 27 that are one step lower are formed. A plurality of convex portions 25, 25 that partially protrude from both sides of the concave portions 27, 27 are formed and come into contact with the gripping opening / closing bodies 4, 4 in a closed state as described later.

In the central portion of the raised portions 21 and 21 in the longitudinal direction, there are non-raised portions 26 and 26 that are not partially raised. By forming the non-raised portions 26, 26, it is easy for the user to insert a finger under the gripping opening / closing bodies 4, 4 in the closed state, and the gripping opening / closing bodies 4, 4 are gripped and opened. It can be rotated so as to be in a lid state.

As shown in FIG. 3, both side ends of the raised portions 21, 21 project outward from the lid 2 and hang downward in order to rotatably support the gripping opening / closing bodies 4, 4. 21a is formed. Round holes aligned coaxially with the hinge shafts 14a and 14a are formed in the mounting portions 21a and 21a.

Next, the gripping opening / closing bodies 4 and 4 will be described. In the present description, the shape of one (front) gripping opening / closing body 4 and the hinge shafts 14a and 14a is the same as the shape of the other (rear) gripping opening / closing body 4 and the hinge shafts 14b and 14b. The description of the grip opening / closing body 4 will be omitted. As shown in FIGS. 1, 2 and 7, the gripping opening / closing bodies 4 and 4 according to the present embodiment mainly include hooks 32 and 32 that engage with the four hinge shafts 14a and 14a, and hooks 32 and 32. Four rising portions 33, 33 that continuously rise from the upper ends and one grip portion 34 that continuously rises from the upper ends of the four rising portions 33, 33 are formed.

As shown in FIG. 3, the gripping opening / closing bodies 4 and 4 have protrusion shafts 31a and 31a protruding in the left-right direction from the engaging portions 31 and 31 hanging from both sides (left and right sides) in the longitudinal direction from the grip portion 34. It is rotatably arranged by rotatably engaging with the round holes formed in the mounting portions 21a and 21a of the lid body 2. Since the protrusion shafts 31a formed on the engaging portions 31 and 31 are formed so as to be aligned coaxially with the hinge shafts 14a and 14a and the support shafts 15a and 15a, when the grip opening / closing bodies 4 and 4 are rotated. , The hooks 32, 32 can have a hinge structure that rotates around the hinge shafts 14a, 14a.

Further, an auxiliary engaging portion 36 that rotatably engages with the left-right end portion of the locked portion 24, which will be described later, is formed at the center of the gripping opening / closing bodies 4 and 4 in the left-right direction. The 36 also has a protruding shaft having the same diameter arranged in the same coaxial direction as the protruding shaft 31a of the engaging portion 31, and fits into a round hole formed at the left-right end of the locked portion 24. As a result, the rotation of the grip opening / closing body 4 and the separation of the lid body 2 are assisted / reinforced.

As described above, since the protrusion shafts 31a and 31a and the hinge shafts 14a and 14a are formed in the coaxial direction of the gripping opening / closing bodies 4 and 4, the rotation can be made smooth. Further, if the protrusion shafts 31a and 31a are formed above the hinge shafts 14a and 14a, the hooks 32 and 32 will rotate more toward the main body 3, and a compact configuration cannot be obtained.

In addition, two gripping opening / closing bodies 4 and 4 are arranged on the front side and the rear side, and each can be opened and closed independently. When the hooks 32 and 32 of one gripping opening / closing body 4 are released, the other gripping opening / closing body As a hinge structure in which the hooks 32, 32 of 4 rotate around the hinge shafts 14a, 14a, the lid body 2 is opened. Further, when the hooks 32 and 32 of both the gripping opening / closing bodies 4 and 4 are released, the lid body 2 can be completely removed.

Next, the engagement between the grip opening / closing bodies 4 and 4 and the hinge shafts 14a and 14a of the main body 3 and the hooks 32 and 32 will be described. As shown in FIG. 1, the grip portion 34 has a shape extending diagonally upward and extending rearward (toward the center of the main body), and its lateral dimension is formed longer than the front-rear dimension. As shown in FIGS. 1 and 6, as described above, the grip portion 34 abuts on the convex portions 25 and 25 in the closed lid state and covers the concave portions 27 and 27 of the lid body 2 surrounded by the raised portions 21. Is placed in. As shown in FIG. 7A, in the closed state, the upper surface of the grip portion 34 has a shape in which the upper surface thereof is gently curved from the upper surface of the raised portion 21.

A plurality of hooks 32, 32 continuous from the lower end of the grip portion 34 are formed in a hook shape, and the hinge shafts 14a, 14a abut and engage with the inside of the hook. In the closed state, the hook mouth of the hook 32 faces outward, and the engaged state of the hooks 32, 32 and the hinge shafts 14a, 14a is maintained. This is because the hinge shafts 14a and 14a engaged with the hooks 32 and 32 are in the vertical direction on the drawing and the hooks are in the horizontal direction on the drawing. The hooks 32 and 32 shield the shaft pull-out direction.

On the other hand, the gripping opening / closing body 4 can rotate from the closed state shown in FIG. 7 (a) to the opened state shown in FIG. 7 (b) with the protrusion axis described above as an axis. This rotation is opened by rotating outward by about 90 degrees to a position stopped by the stopper 37 described later. This rotation angle is 90 degrees in the present embodiment, but is set to about 90 degrees within a range that allows an error.

In this open state, the hook mouth of the hook 32 faces downward in the drawing, and the engagement state between the hooks 32 and 32 and the hinge shafts 14a and 14a can be released. This is because the hinge shafts 14a and 14a engaged with the hooks 32 and 32 are in the vertical direction on the drawing and the hook mouth is in the vertical direction on the drawing. The direction of the shaft pulling out and the direction of the hook are the same. Then, when the grip portion 34 of the grip opening / closing body 4 is picked up and the lid body 2 is pushed upward, the hinge shaft 14a is disengaged from the hook opening of the hook 32 as shown in FIG. It becomes possible to perform a lid opening operation for opening the lid body 2.

The grip portion 34 is formed with rising portions 33, 33 in the vertical direction from the upper ends of the hooks 32, 32, is curved from the upper ends of the rising portions 33, 33, and the vicinity of the tip is in the horizontal direction. In the present embodiment, the grip portion 34 is curved, but it may be bent from the rising portion in the vertical direction so as to be in the horizontal direction. Since the grip portion 34 is bent and curved, the tip of the grip portion 34 faces upward in a state where the grip opening / closing body 4 is rotated. Further, a recess 27 is formed in the lid 2 arranged in the closed state of the grip opening / closing body 4, and a curved portion in which the grip portion 34 is curved is formed. A predetermined gap S is formed between the two. The user can insert a finger into the gap S to facilitate the gripping opening / closing body 4.

That is, the user raises the grip portion 34 with a finger to rotate the grip opening / closing body 4, and pulls the grip portion 34 upward while grasping the grip portion 34 with a finger, so that the lid body 2 can be opened with one touch without changing hands. Can be done. By forming this gap S, the user can easily pick and open the grip portion 34 even in a small storage box.
