Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a school lunch tray used mainly in hospitals and the like for carrying a plurality of tableware of different shapes.

(Prior art) In hospitals, etc., generally dishes are arranged on tableware in the kitchen, a staple food and a side dish are placed on a tray, and a large number of trays are arranged in a handcart and transported to each room, from where the tray is delivered to each person. The food is being served.

In hospitals, etc., trays are usually transported using handcarts, and many of them are served at the same time, so there is no room to transport the trays quietly. Because dishes tend to slip off the tray, the surface of the tray is generally formed with a plurality of engaging recesses for receiving the bottom of the dishes.

However, in conventional school lunch trays, the shapes of the engaging recesses are limited to several types, often three to four types, and the shapes of the tableware are also limited to three to four types. For this reason, it was extremely inconvenient because it was not possible to arbitrarily select tableware according to the dish.

Furthermore, although such trays are often covered with lids for purposes such as heat retention, even if this provides a heat retention effect, it has the disadvantage of heating cold dishes instead.

(Purpose of the invention) In view of the above problems, the purpose of the invention is to provide a school lunch tray that can accommodate tableware of various shapes and that can prevent heat transfer from one side of the dish to the other. be.

(Structure of the invention) The present invention has a multi-recessed part in which an engaging recess for receiving the bottom of tableware and an engaging recess for receiving the bottom of tableware of other shapes are formed at the same position on the surface of the tray body. Furthermore, a lid made of a heat insulating material that covers the surface of the tray body is removably attached to the tray body, and the lower surface of the lid has a recess at a location that fits the multiple recesses, and A partition wall is provided between the recesses and is in contact with the surface of the tray body, and the tray body can accept the bottoms of tableware of various shapes, so that tableware of a shape suitable for the daily menu can be selected. Furthermore, even if dishes containing dishes of different temperatures are placed on the same tray body, the transfer of heat from one to the other will be prevented by the lid.

(Embodiment) The present invention will be explained below with reference to the embodiment shown in the drawings. As shown in FIG. It is made up of body 2.

As shown in the figure, the surface of the tray body 1 has a plurality of multiple recesses 3, 4, 5,
6 is formed. The multiple recesses 3.4, 5, 6
are a plurality of engaging recesses 7, 8, whose cross-sectional shapes correspond to the depth of the container and have various shapes such as circular and rectangular shapes.
9, and the engaging recesses 7, 8, and 9 are shaped so that a protrusion protruding from the bottom of a tableware (not shown) can be engaged therewith.

To explain these engaging recesses 7, 8, and 9 in more detail, the multiple recesses 3, 4, 5, and 6 have the first engaging recess 7 with the largest cross-sectional area, and the other engaging recesses have the first engaging recess 7. 1 is provided on the bottom surface of the engaging recess 7.

For example, by recessing the bottom surface of the first engaging portion 7 to form the second engaging recess 8, and further recessing the bottom surface of the second engaging recess 8 to form the third engaging recess 9. , one multiple recess 3 may be formed, or a plurality of second engagement recesses 8 may be arranged in parallel by recessing a plurality of locations on the bottom surface of the first engagement recess 7, and each of the second engagement recesses 8 may be arranged in parallel. The bottom surface of the second engagement recess 8 is recessed to form a third
By forming the engagement recesses 9, one multiple recess 4 may be constructed. In any case, the cross-sectional shapes of the respective engaging recesses 7, 8, and 9 may be similar to each other, or may be different shapes.

In the above, the engagement recess is formed by recessing the surface of the tray body 1;
In this way, the protrusion 10 may be provided without being recessed, and the engagement recess may be defined by the protrusion 10.

Further, the multiple recesses may be formed of only one engagement recess as shown in 4 in the figure. In this case,
One tableware may be engaged with the engagement recess, or a plurality of tableware formed by dividing the tableware into a plurality of pieces may be engaged.

The lid body 2 that is placed over the tray body 1 having the above structure has a portion that fits the multiple recesses 3, 4, 5, and 6 on the side facing the multiple recesses 3, 4, 5, and 6, that is, the lower surface thereof when the lid body 2 is fitted onto the tray body 1. It has recesses 3a, 4a, 5a, and 6a, and the surface of a partition wall 11 that partitions the recesses 3a, 4a, 5a, and 6a is in contact with the surface of the tray body 1.

That is, when the tray body 1 is covered with the lid 2, the surface of the partition wall 11 of the lid 2 comes into contact with the surface of the tray body 1. However, if the partition walls 11 are simply brought into contact with each other in this way, the partition wall 11 will hit against tableware (not shown) during transportation, and when these school lunch trays are stacked and stored when not in use, the tray main body 1 and the lid body 2 will be separated. To prevent this, multiple recesses 3, 4, 5, 6 are provided.
It is preferable that a fitting part 12 is provided protrudingly around the periphery of the housing, and the recess is engaged with the fitting part.

Furthermore, as shown in FIG. 3, a heat insulating material 13 such as asbestos or plastic foam material is provided inside the partition wall 11 and bottom wall that define the recesses 3a, 4a, 5a, and 6a of the lid body 2. ing.

Furthermore, as shown in FIG. 4, on the top surface of the lid body 2,
A protrusion 14 is formed at a location that fits around the multiple recesses 3, 4, 5, and 6, and a groove 15 into which the protrusion 14 can be fitted is formed on the back surface of the tray body 1. These protrusions 14 and grooves 15 are used when the lid body 2 is used as a table stand.
4 and the groove 15, the tray body 1 placed on the lid body 2 is prevented from shifting.

Next, when using such a school lunch tray, select tableware with a shape suitable for the menu, select the engaging recesses that fit the bottom of the tableware, and then engage the tableware with the lid. 2
If you cover the trays so that they overlap, the tray body 1
The recessed portion of the lid body 2 is fitted into the fitting portion.

(Effect) The present invention, as explained above,
A plurality of engaging portions 7, 8, 9, and 10 are formed on the bottom walls of the recesses 3, 4, 5, and 6 of 0 in accordance with the sizes of the plurality of tableware that can be freely engaged with and stored in the bottom of the tableware. Since the bottom of a tableware of any size can be freely engaged with one recess, 3, 4, 5 or 6,
Therefore, tableware of any size can be stored in one recess.

Further, in the present invention, the recess 3 of the tray body 10,
The recesses 3a of the lid body 2,
4a, 5a, and 6a are formed with protrusions (engaging portions) 12 that can be freely engaged with each other, so that the lid body 2 is fixed to the tray body 10, so that even if the tray body 10 is tilted, Not only does the lid 2 not slip on the tray body 10, but the protrusions 12 are provided on the periphery of each of the recesses 3, 4, 5, and 6. Since the strip 12 engages with the inner surface of the recesses 3a, 4a, 5a, 6a of the lid body 2, the tableware storage formed by the recesses 3a, 4a, 5a, 6a and the recesses 3, 4, 5, 6 The airtightness of the space is further maintained.

Furthermore, even when hot and cold dishes are placed on the same tray body and the lid is placed on top, the partition wall that separates the recesses in the lid comes into contact with the surface of the tray body, so a pair of multiple recesses are formed. The recesses constitute a nearly airtight storage room, and the lid is made of a heat insulating material, so the transfer of heat from one side of the storage room made up of multiple recesses and recesses to the other is minimized. Therefore, hot dishes and cold dishes are not affected by temperature mutually.
