The inner side portion of the lower opening 31 of the buckle 3 is located in the constricted portion 112, and functions as a member that makes the locking state on the lower side of the buckle 3 stronger.

In the figure, the container body 1 is in the form of a horizontally long rectangular shape having four side surfaces, and the corner portions in plan view are rounded, and are shown as having the container projecting pieces 11 and 11 on the opposing short side surfaces. It is done.
In addition, it is good also as what provides the partition which divides the area | region which accommodates a rice, a side dish, etc. in the accommodating part of the container main body 1.

  Further, the container projecting piece 11 is not limited to the pair of opposing short side surfaces as in the present embodiment, but may be provided on each of the pair of opposing long side surfaces. Further, the container projecting piece 11 is not limited to one on each side as in the present embodiment, but may be plural.

The lid 2 is a fitting member that closes the opening of the container main body 1 so as to cover the entire surface, and includes a lid protrusion 21 that protrudes outward from the outer edge. The lid projecting pieces 21 are provided at corresponding outer edge positions to be disposed above the container projecting pieces 11 provided on the container body 1 when the lid 2 is fitted to the container body 1. By being inserted into the upper opening 32 of the buckle 3 to be described later, the cover 2 and the buckle 3 function as one that is maintained integrally.
In the figure, as in the case of the container main body 1, the lid 2 is shown as having rounded corner portions in plan view, and provided with lid protrusions 21 and 21 at a pair of opposing short side edge portions. .

  Further, as shown in FIG. 7, for example, the lid projection piece 21 can be provided with a concave portion 211 whose upper surface is thin. The recessed portion 211 has a thickened convex portion 321 provided on the upper surface of the upper opening 31 of the buckle 3 described later, and functions as locking the upper side of the buckle 3.

  Further, as shown in FIG. 8, for example, the lid projection piece 21 may be provided with necked portions 212 and 212 whose both side surfaces are thin. The inner side portion of the upper opening 32 of the buckle 3 is located in the constricted portion 212, and functions as a member that makes the locking state on the upper side of the buckle 3 stronger.

  The buckle 3 is a locking member that maintains the closed state of the lid 2 with respect to the container body 1 and has two openings at the upper and lower positions. The upper opening 32 is an upper opening 32 engageable with the lid projection 21, and the lower opening is a lower opening 31 engageable with the container projection 11. The buckle may be made of, for example, a flexible elastic member such as an elastomer, and specifically, it is desirable that the buckle be made of silicone resin. In addition, although mentioned just in advance, in this invention, the buckle which consists of hard members is not excluded.

Further, as shown in FIG. 9, for example, the buckle 3 is provided with a convex portion 311 which becomes thick in the lower part of the inner surface of the lower opening 31, and thick in the inner upper part and the inner surface side of the upper opening 32. The projection 321 can be provided.
The convex portion 311 of the buckle 3 is positioned in the concave portion 111 when the container projecting piece 11 of the container main body 1 is inserted into the lower opening 31 and functions as locking the lower side of the buckle 3 Become. On the other hand, when the lid projection 21 of the lid 2 is inserted into the upper opening 32, the convex portion 321 of the buckle 3 is positioned in the concave portion 211 and functions as locking the upper side of the buckle 3.

  Here, the relationship between the container projection 11 provided in the container main body 1 and the lower opening 31 provided in the buckle 3 and the lid projection 21 provided in the lid 2 and the upper opening 32 provided in the buckle 3 will be described respectively. explain. As shown in FIG. 10, the thickness d11 of the container projecting piece 11 is larger than the height t31 on the convex portion 311 (tip) provided at the lower part of the inner surface of the lower opening 31 (d11> t31). The lower opening 31 is locked. Further, the thickness d21 of the lid projection 21 is larger than the height t32 of the lower portion (tip) of the convex portion 321 provided on the inner surface upper portion of the upper opening 32 (d21> t32), and the lid projection 21 is locked in the upper opening 32 It has become a thing.

  As a result, the buckle 3 does not come off unobtrusively from the container projecting piece 11 and the buckle 3 does not come off unobtrusively from the lid 2, and the locked state of the buckle 3 with respect to the container projecting piece 11 and the lid 2 The locking state of the buckle 3 is more reliable. In addition, engagement of the buckle 3 with the container projecting piece 11 and the lid 2 can be achieved by providing the convex portion 311 in the lower portion of the inner surface of the lower opening 31 or providing the convex portion 321 in the inner upper portion and the inner surface side of the upper opening 32. The stop state can be made more reliable.

In FIG. 1 to FIG. 4, the buckles 3 are shown as being provided with the container projecting pieces 11, 11 and the lid projecting pieces 21, 21 so as to be engageable and disengageable respectively.
Therefore, in the lunch box 10 of the present invention, after the lid 2 is fitted to the opening of the container body 1, the lower openings 31 of the buckles 3 are respectively inserted into the container projecting pieces 11 and 11 of the container body 1, The upper openings 32 of the buckles 3 are inserted into the lid projections 21, 21 of the lid 2. Thereby, the closed state of the lid 2 with respect to the container main body 1 is maintained by the buckle 3.

  Further, in the present invention, for example, as shown in FIG. 9, the buckle 3 may further include a convex portion 322 having a large thickness at the lower part of the inner surface of the upper opening 32. Under the present circumstances, as shown in FIG. 7, the cover protrusion 21 shall be provided with the recessed part 213 which becomes thin in the lower surface side so that the latching state with the upper opening 32 of the buckle 3 may become favorable. it can. That is, the concave portion 213 is formed on the lower (rear) surface side of the lid protrusion 21. A convex portion 322 having a thickness provided on the inner lower portion of the upper opening 32 of the buckle 3 is located in the concave portion 213, and together with the concave portion 211 and the constriction portion 212 provided on the lid projection 21, the upper side of the buckle 3 Function as a means to make the locking state of

  Further, in the present invention, as shown in FIG. 12, for example, the buckle 3 may have a structure in which the inner surface of the lower opening 31 or the inner surface of the upper opening 32 is not provided with a thick projection. At this time, the container projecting piece 11 and the lid projecting piece 21 can have, for example, the following structure so that the locking state with the lower opening 31 and the upper opening 32 becomes good.

  First, for example, as shown in FIG. 13, the container projecting piece 11 can be provided with the thick portion 121 at the lower end of the tip. That is, the thick portion 121 is formed on the back (rear) surface side of the container projecting piece 11. The thick portion 121 is positioned over the lower opening 31 of the buckle 3 and functions as a hook for locking the lower side of the buckle 3.

  Further, as shown in FIG. 14, for example, the container projecting piece 11 may be provided with the wide portions 122 and 122 at both end portions of the tip. The wide portion 122 is also located over the lower opening 31 of the buckle 3 and functions as a member that makes the locking state on the lower side of the buckle 3 stronger.

  On the other hand, for example, as shown in FIG. 15, the lid projection piece 21 can be provided with a thick portion 221 at the upper end of the tip. The thick portion 221 is located over the upper opening 31 of the buckle 3 and functions as a member that locks the upper side of the buckle 3.

  Further, as shown in FIG. 16, for example, the lid projection 21 may be provided with the wide portions 222 at both end portions. The wide portion 222 also lies over the upper opening 31 of the buckle 3 and functions as locking the upper side of the buckle 3.

  Therefore, also by combining the container projecting piece 11 having the thick portion 121 and the wide portion 122 with the lid projecting piece 21 having the thick portion 221 and the wide portion 222, the lid 3 is closed to the container body 1 by the buckle 3. The lid can be maintained.

  Furthermore, in the present invention, in the buckle 3, the pressure contact force of the upper opening 32 to the lid protrusion 21 is larger than the pressure contact force of the lower opening 31 to the container protrusion 11, in other words, the pressure contact of the lower opening 31 to the container protrusion 11 The force may be smaller than the pressing force of the upper opening 32 against the lid projection 21.

Such a buckle 3 can be achieved by mutually adjusting the height t31 of the lower opening 31 with respect to the thickness d11 of the container projecting piece 11 and the height t32 of the upper opening 32 with respect to the thickness d21 of the lid projection 21.
In addition, such pressure contact force is determined by the size of the convex portion 311 of the lower opening 31 with respect to the depth of the concave portion 111 of the container projecting piece 11 and the size of the convex portion 321 of the upper opening 32 with respect to the depth of the concave portion 211 of the lid projection 21. It can also be achieved by adjusting the dimensions of one another.

At this time, assuming that the lower end portion (the end portion on the lower opening 31 side) 3L is bent outward as shown in FIG. 9B, the buckle 3 is in contact with the pressure in the lid opening operation of the lunch box. Is desirable because the lower end 3L of the buckle 3 located on the smaller side is easier to pick.
Therefore, if the lower end 3L of the buckle 3 is picked and pulled outward, the locked state of the lower opening 31 with respect to the container projecting piece 11 is released before the locked state of the upper opening 32 with respect to the lid projecting piece 21 is released. As a result, the opening operation of the lunch box becomes easy. Moreover, since the buckle 3 is integrated without being detached from the lid 2 at this time, the risk of losing can be eliminated.

  Further, in the present invention, the buckle 3 has a pressure contact force of the lower opening 31 with respect to the container projecting piece 11 larger than a pressure contacting force of the upper opening 32 with respect to the lid projecting piece 21; in other words, pressure contact of the upper opening 32 with respect to the lid projecting piece 21 The force may be smaller than the pressing force of the lower opening 31 against the container projecting piece 11.

Such a buckle 3 can also be achieved by mutually adjusting the height t31 of the lower opening 31 with respect to the thickness d11 of the container projecting piece 11 and the height t32 of the upper opening 32 with respect to the thickness d21 of the lid projection 21. .
In addition, such pressure contact force is determined by the size of the convex portion 311 of the lower opening 31 with respect to the depth of the concave portion 111 of the container projecting piece 11 and the size of the convex portion 321 of the upper opening 32 with respect to the depth of the concave portion 211 of the lid projection 21. It can also be achieved by adjusting the dimensions of one another.

At this time, assuming that the upper end portion (the end portion on the upper opening 32 side) 3U is bent outward as shown in FIG. 17, the buckle 3 has a small contact pressure in the opening operation of the lunch box. It is desirable because the upper end 3U of the buckle 3 located in the above becomes easy to pick.
Therefore, if the upper end portion 3U of the buckle 3 is picked and pulled outward, the locked state of the upper opening 32 with respect to the lid protruding piece 21 is released before the locked state of the lower opening 31 with respect to the container protruding piece 11 is released. As a result, the opening operation of the lunch box becomes easy. Moreover, since the buckle 3 is integrated without being detached from the container body 1 at this time, the risk of losing can be eliminated.

Further, in the present invention, as shown in FIG. 18, the lunch box 20 further includes a second container 4 placed on the upper edge of the container body 1 and located between the lid 2 and the container 2. It can also be done.
In the lunch box 20, for example, only the rice can be stored in the container body 1, and the food etc. can be stored in the second container 4. In the present embodiment, the provision of the partition in the housing portion of the container body 1 is not denied.
