Description of the Related Art Trays made of heat-resistant plastic are widely used for business purposes in hospitals, restaurants, etc., and are repeatedly washed or disinfected at high temperatures each time they are used. In addition, when used for business purposes, a large number of trays are used at one time, and each time they are transported and washed. Further, since a large number of trays are stacked and used in terms of workability, transportability, and storability, square trays are often used. As shown in FIGS. 6 to 8, such a conventional tray is formed by injection molding a synthetic resin such as a heat-resistant plastic. As shown in FIGS. 6 and 7, the tray 2 includes a substantially square mounting portion 4 having a corner 3 formed in an arc shape, and a rising portion 5 which rises up from the outer periphery of the mounting portion 4 in a direction outward. And The mounting section 4 has a double-sided 4A,
4B is formed flat. The space between the mounting portion 4 and the rising portion 5 is curved as shown in FIG. The rising portion 5 has a curved corner portion 6 which rises from the arc-shaped corner portion 3 of the mounting portion 4 and has a flange portion 7 (see FIG. 8) protruding outward on the outer periphery of the upper surface 5A. Is done. Reference numeral 8 denotes a seat formed on the lower surface 4B of the mounting portion 4. As shown in FIG. 8, a large number of such trays 2 are stacked during transportation or storage.

いう問題があった。The conventional tray according to the above configuration is required to have strength enough to withstand repeated use, but is required to be light in weight from the viewpoint of workability. However, the conventional tray 2 according to the above configuration, because it is molded by injection molding, for example, in the case overall shape is square, the resin portion far from the arc portion centered on the center O 1 (mounting portion Since the resin finally flows into the peripheral portion 4C of the corner portion 4 and the corner portion 6) of the rising portion 5, a plurality of flows of the resin are joined to the peripheral portion 4C or the corner portion 6 with a delay during molding. A weld mark (weld line) L (see broken lines in FIGS. 6 and 7) may occur, resulting in a decrease in strength. Further, if the peripheral portion 4C of the corner portion 3 of the mounting portion 4 collides with an object during use, breakage is likely to occur. For this reason, if the mounting portion 4 or the rising portion 5 is made thicker to improve the strength, there is a problem that the weight of the entire tray increases and the workability deteriorates. Also,
When used in hospitals and the like, there is a problem that the weight of the tray makes it difficult for patients to handle. Furthermore, in the above-mentioned conventional trays 2, when stacked, as shown in FIG. 8, there is no gap between the upper and lower trays 2 which fits into each other and communicates with the outside. However, there was a problem that workability was poor.

The strength of the corner portion 16 of the mounting portion 14 located below the bulging portion 20 and the strength of the corner portion 16 of the mounting portion 14 are also strengthened. The bulging portion 20 is located at the corner 1
6 further extends left and right by a predetermined length to prevent lateral displacement when the trays 12 are stacked. In addition, the lower surface 21 of the bulging portion 20 is formed flat. Lower surface 2
1 is placed on the upper surface 15A of another lower tray when the trays 12 are stacked. The height H is determined in advance so as to form a gap S communicating with the outside between the other trays 12 below when the trays 12 are stacked.
In other words, by forming the gap S, it is possible to wash and disinfect by pouring hot water from the outside and dry it by blowing hot air in a state where many trays 12 are stacked.

The tray 12 includes a resin tray 12 having a flat non-circular mounting portion 14 and a rising portion 15 that rises up from the outer periphery of the mounting portion 14 inclining outward.
By forming the bulging portion 20 having a predetermined thickness W and a height H along the upper end 15A at the corner 16 of the outer periphery of the rising portion 15, the corner peripheral portion 14C of the mounting portion 14 and the rising portion 15 are formed.
Since the strength of the corners 16 can be improved, the entire tray 12 can be made thinner and lighter. In addition, at the time of stacking, since the stacking is performed via the bulging portion 20, a gap S communicating with the outside can be formed between the upper and lower trays 12, 12, and operations such as washing and drying can be performed in the stacked state. It can be carried out. Further, the bulging portion 20
Are further extended right and left from the corner portion 16 by a predetermined length, so that when they are stacked, they can be smoothly stacked without laterally shifting front and rear and left and right.

言うまでもない。FIG. 5 shows a modification of the tray 12. FIGS. 5 (A) to 5 (C) show the trays having an elliptical shape, a semicircular shape and a rectangular shape, respectively. As shown in the figure, a bulging portion is formed at a portion indicated by a broken line. In the above-described embodiment, the tray in which the corner of the mounting portion is formed in an arc shape and the corner of the rising portion is formed in a curved surface is described, but the present invention is not limited to this, and the corner or the corner is formed in a straight line. For example, they may be formed so as to intersect at a right angle in cross section. Although the flange 17 is provided on the outer periphery of the upper surface 15A of the rising portion, the same effect as in the above embodiment can be obtained without providing the flange 17. In addition, the height H of the bulging portion 20 need not be larger than the gap S required for washing and drying, and it is needless to say that the height H is determined in consideration of the storability.

る。As described above, according to the present invention, there is provided a resin tray having a flat non-circular mounting portion and a rising portion which rises from the outer periphery of the mounting portion so as to incline outward. By forming a bulging portion having a predetermined thickness and a predetermined height along the upper end at the corner of the outer periphery of the rising portion, it is possible to reduce the weight, and to reduce the weight of the mounting portion around the corner and the rising portion. This has the effect of improving the strength of the corners of the part and extending the life of the tray. Further, even when the trays are stacked, a work space for washing, drying, etc. is secured in each tray, so that there is an effect that the working efficiency is improved.
