As shown in FIG. 2, the tray 1 on which the cooked food is provided is disc-shaped, and four legs 2 are installed. A hemispherical cover 3 is arranged to cover the top of the tray 1. A handle 3a is provided on the front of the cover 3.

A pedestal 4 extends from each leg 2 and is connected to the other leg 2 which is disposed opposite. Accordingly, the pedestal 4 has a cross shape, and the air path 5 is provided at the intersection point.

Here, in the present invention, the rotation angle of the cover 3 is adjustable in two stages 110 ° and 160 °, an adjustment device for this is provided at the hinge point of the cover (3). The configuration of the adjusting device is shown in detail in exploded perspective view in FIG. 3.

As shown, the disc 11 is provided on the inner end of the hinge shaft 10 for rotatably supporting the cover, and the square 12 is integrally formed on the other end.

The hinge cylinder 20 is rotatably fitted to the hinge shaft 10. Therefore, a hinge hole 23 into which the hinge shaft 10 is rotatably fitted is formed in the center of the hinge cylinder 20. The boss 22 forming the hinge hole 23 protrudes by a predetermined length on the outer surface of the hinge cylinder 20. In addition, the rim 21 forming the outer circumferential surface of the hinge cylinder 20 also extends along the protruding direction of the boss 22, and protrudes more than the boss 22. Thus, a space portion is formed between the rim 21 and the boss 22.

A locking groove 24 is formed toward a center from a portion of the outer circumferential surface of the hinge cylinder 20. The locking groove 24 is formed in a shape that also exposes the outer circumferential surface of the protruding boss 22. In addition, the locking groove 24 is also formed in the protruding rim 21, the protruding rim 21 has a ring-shaped structure is a part cut.

On the other hand, as shown in Figure 4, the inner side of the hinge cylinder 20, a circular recess 25 is formed in the center. The groove part 26 is formed in any part which comprises the outer peripheral surface of the recessed part 25. The disc 11 and the hinge cylinder 20 are not directly abutted, but as shown in FIG. 3, a connecting cylinder 30 is interposed therebetween. A hinge hole 33 into which the hinge shaft 10 is fitted is formed at the center of the connecting cylinder 30. A circular protrusion 31 is formed on the outer surface of the connecting cylinder 30, and a protrusion 32 is formed on the protrusion 31 in the radial direction. The projection part 32 is inserted into the groove part 26 of the hinge cylinder 20, and serves to rotate the connection cylinder 30 together with the hinge cylinder 20.

Again, referring to Figure 3, the hinge bracket 60 fixed to the cover and rotated together is fitted into the locking groove 24 of the hinge cylinder 20, thereby transmitting the rotational force of the cover to the hinge cylinder 20. . The outer circumferential surface of the hinge bracket 60 has the same shape as the curvature of the hinge cylinder 20, and its arc length is slightly longer than the arc length of the locking groove 24 formed on the outer circumferential surface of the hinge cylinder 20. In particular, both sides of the hinge bracket 60 is in contact with both side walls of the locking groove (24). In addition, at the upper end of the outer side of the hinge bracket 60, an angle limiting groove cover portion 63 fixed to the cover in the direction of the cutout of the rim 21 is integrally formed. The angle limiting groove cover portion 63 also has the same shape as the curvature of the hinge cylinder 20. A pair of latches 61 are formed at both lower ends of the hinge bracket 60 to enter the locking grooves 24 formed at both sides of the boss 22. Since the portion of the inner wall of the latch 61 is in close contact with the boss 24 to smoothly rotate the hinge cylinder 20 together with the cover, the inner wall of the latch 61 has the same curvature as the curvature of the boss 24. Have A locking jaw 62 protrudes and is formed in the center of the outer side of the hinge bracket 60. This locking step 62 is limited to the rotation angle of the cover 110 °.

The fixing cylinder 40 is fixed to the hinge shaft 10 portion, that is, the square portion 12, extending from the hinge hole 23 of the hinge cylinder 20. Fixing cylinder 40 is fixed to the tray, the square hole 41 is formed so that the square portion 12 is fitted in the center thereof. The square hole 41 is formed in the fixed cylinder 40, and the reason for forming the square portion 12 on the hinge shaft 10, which is inserted into the square hole 41 and cannot be rotated, together with the hinge cylinder 20 This is to prevent the hinge shaft 10 from ever rotating.

As shown in FIG. 5, the angle adjusting groove 42 including the square hole 41 is formed on the inner surface of the fixing cylinder 40. The angle adjusting groove 42 is formed from an outer circumferential portion of the fixing cylinder 40 and is formed to a size enough to include a square hole 41, thereby limiting the rotation angle of the hinge bracket 60 to 180 °. do. That is, since the locking jaw 62 of the hinge bracket 60 is in contact with both side walls of the angle adjustment groove 42, the rotation angle of the hinge bracket 60 is limited to 160 degrees.

In addition, the fixing cylinder 40 is formed with an adjustment hole 43 penetrating the inner and outer side surfaces. The adjusting hole 43 is located in the angle adjusting groove 42, and is formed at a position where the locking angle of the locking jaw 62 is 90 °. Bushing 80 is fitted into the adjustment hole 43, a portion of the bushing 80 protrudes outward from the adjustment hole (43). In particular, the portion of the bushing 80 protruding outward is longer in diameter than the portion located in the adjusting hole 43.

The adjustment knob 50 is movably fitted to the bushing 80. The adjustment knob 50 is comprised of the handle 51 which is not fitted to the bushing 80, and the adjustment shaft 51 which is movably fitted to the bushing 80. As shown in FIG. On the other hand, the return spring 70 is disposed in the portion of the bushing 80 protruding outward, so that the return spring 70 elastically supports the adjustment shaft 51 in the inward direction. Therefore, when the external force is not applied to the adjustment knob 50, the adjustment shaft 52 is always in a state protruding from the adjustment hole 43, thereby preventing the locking jaw 62 of the hinge bracket 60 rotation.

Hereinafter, the operation of adjusting the cover opening angle according to the present embodiment configured as described above will be described in detail with reference to FIGS.

First, FIG. 6A illustrates the positions of the hinge bracket 60 and the hinge barrel 20 in a state where the cover is closed, and a portion indicated by a circle is a position where the adjustment shaft 52 of the adjustment knob is disposed. As shown, the hinge bracket 60 is directed to the right, so the hinge cylinder 20 also has an upper portion of the locking groove 24 toward the right.

In this state, when the cover is rotated counterclockwise, the hinge bracket 60 and the hinge barrel 20 rotate together, and as shown in FIG. 6B, the locking jaw 62 of the hinge bracket 60 is adjusted. It is caught by the adjusting shaft 52 protruding from 43, so that it can no longer be rotated. Therefore, the rotation angle of the cover 3 is limited to 110 degrees.

To fully open the tray 1 by rotating the cover 3 to 160 °, grasp the handle 51 of the adjustment knob 50 and pull it back. Then, the adjustment shaft 52 retreats together while compressing the return spring 70, so that the adjustment shaft 52 is accommodated in the adjustment hole 43. Therefore, since the locking step 62 is not caught by the adjustment shaft 52, the cover 3 can be fully flipped to 160 degrees as shown in FIG. 6C.

On the other hand, if the force pulling the adjustment knob 50 is removed, the adjustment shaft 52 will return to the original position by the return spring 70, and will be in the state exposed by the adjustment hole 43. FIG. Therefore, to close the cover 3, the adjustment knob 50 must be pulled back as in the above-described operation.

As described above, according to the present invention, the opening angles of the cover can be adjusted to 110 ° and 160 ° in two stages, so that the cover can be kept open only 110 ° while the food container is in use. Therefore, the extent to which heat is released from the food provided in the tray can be suppressed, and the food is not easily cooled, and thus the taste of the food can be maintained for a long time.

In addition, while the food storage container is in use, the cover is rotated only 110 ° so that the air path is not blocked. Therefore, a sufficient amount of air can be supplied to the air path, thereby preventing the air path from being weakened or even turned off.
