Description

[Detailed Description of the Invention] The present invention relates to a lunch box mainly made of aluminum.

Generally, this type of bento box consists of a body and a lid, and is not airtight because the structure is such that the lid is simply placed over the body of the box.

Therefore, side dishes containing a lot of water, such as broth, are usually placed in a special lidded food box, sealed, and stored in a part of the bento box.

Therefore, when eating a meal, after removing the lid of the bento box, it is necessary to remove the lid of the vegetable box, and since the vegetable box is stored inside the body, it is difficult to remove the lid.

Also, when the box is empty, the food box moves inside the bento box, and the noise caused by this movement is a concern.

Furthermore, since there is no latching relationship between the meat and the lid, there are inconveniences such as rattling if the meat is not wrapped in wrapping paper or a packaging bag.

The present invention has been proposed in view of the above points, and the body, the lid, and the vegetable box, which itself has no lid, are integrally fixed with a single hanging structure, and at least the vegetable box is fixed in one body. The purpose is to be able to seal it.

To explain the drawing below, it consists of a rectangular aluminum body 1, a lid 2, and a vegetable box 3 which itself has no lid. An elastic gasket 4 made of silicone rubber or other synthetic rubber is interposed between the opposite back side of the lid 2, and a metal steel wire is folded into a substantially groove shape on the three opposite sides of the lid 2, spanning the bottom surface of the body 1. A pair of bent latches 5, 5 are rotatably coupled together, a recessed step 6, 6 is formed at the bottom of the body 1 for hooking the latches, and the lid 2 is closed. is hung on the concave steps 6, 6 of the meat 1 to fix the meat 1, the lid 2, and the vegetable box 3, and at least the opening surface of the vegetable box 3 is sealed.

In FIG. 1, the opening surface periphery 31 of the vegetable box 3 placed and stored on the bottom of the meat 1 and the peripheral edge 11 of the meat 1 are set at approximately the same height.

Then, an inner lid 7 made of synthetic resin is removably fitted inside the lid 2, and grooves 8, 8□ are formed in the inner lid 7 at positions facing the periphery 31, 11 of the vegetable box 3 and the meat 1. After molding, silicone rubber elastic packing 4, 4 is placed in the concave groove.
I am wearing ゜.

In the figure, reference numerals 9, 9 are bulges formed on the inner bottom of the meat 1, and the remaining one side of the vegetable box 3, which has three sides in contact with the inner wall surface of the meat, is brought into contact with it to prevent the vegetable box 3 from moving. position.

Note that the vegetable box 3 has a body 1 in FIG.
It can be stored and positioned on the left side as well as the right side.

Reference numeral 10 indicates a gap formed between the lid plate 71 of the inner lid 7 and the back surface of the lid 2.

7, 8 and 9 show that the opening periphery 31 of the shallow-bottom vegetable box 3 is placed on the opening periphery 11 of the deep-bottom body 1, and a concave groove 82 is formed on the periphery 31. It has a structure in which an elastic gasket 4 made of silicone rubber is attached to the lid 2 so that it directly adheres to the back surface of the lid 2.

The latch 5 is formed by bending a metal steel wire with a diameter of about 3 mm into a groove shape (U), flattening both ends thereof, opening a shaft (L51), and attaching a shaft 12 to two opposite sides of the lid 2 so as to be freely rotatable. Join.

Reference numeral 13 indicates a bearing member of the latch 5, reference numeral 14 indicates a bearing reinforcing plate located in the recess 15 of the bearing portion, and reference numeral 16 indicates a set screw for fixing the bearing member 13 to the side surface of the lid.

The recessed steps 6, 6 formed at the bottom of the body 1 are such that when the lid 2 is closed and the latches 5, 5 are rotated in the direction of arrow a in FIG. The latch is hung perpendicularly to the shaft against the elastic pressure of the gasket 4, and the horizontal side 51 of the latch is stepped to the extent that it does not protrude from the bottom of the body 1.

Since the present invention has the above-mentioned configuration, the body 1 that stores the vegetable box 3
By closing the lid 2 and hooking the latches 5, 5 to the recessed part 6.6 of the body, the body 1, the lid 2, and the dish box 3 are fixed together with a single latching structure and operation. Moreover, at least the vegetable box 3 is sealed via the packing 4.

Therefore, even if side dishes containing water such as broth are placed in the vegetable box 3 which itself has no lid, it is safe because the juice of the side dishes will not enter the rice or leak outside.

In addition, since the latches 5, 5 are formed by bending metal steel wire into a groove shape and straddle the bottom surface of the meat 1, the latches 5, 5 are pressed evenly against the opening surface periphery 11.31 of the meat 1 and the vegetable box 3. , body 1, lid 2,
There is no bias in the fixing force of the three parts of the vegetable box 3, and rattling is prevented.

Moreover, the sealing effect of the opening surface of the food box 3 is also reliable.

By setting the opening surface periphery 11 of the body 1 at the same height as the opening surface periphery 31 of the vegetable box 3 as shown in FIGS. 1 to 3,
The rice meat 1 can also be sealed via the elastic gasket 4, which is convenient as it can prevent moisture from leaking out.

Further, in FIGS. 1 to 3, chopsticks C, a fork, etc. can be accommodated in the gap 10 formed between the back surface of the lid 2 and the inner lid 7 without being exposed to the outside.

In addition, the outer bottom of the bulges 9, 9 for positioning the vegetable box 3 so that it does not move is recessed by the amount that is raised on the inner bottom of the body 1, and this is exactly the side of the latches 5, 5. The finger rest of 51 is recessed and feels good.
