  By the way, the simplest structure of the bottom surface of the tray container is a bottom having a flat surface. First, ribs are employed on the bottom surface and the wall surface in order to ensure the overall strength. Subsequently, in recent years, with the diversification of this type of tray container, a tray container having a bottom structure corresponding to the characteristics of the objects to be accommodated therein has been developed. Such a development direction is the same for a tray container using a non-foamable resin sheet and a tray container using a foamable resin sheet.

  Various configurations have also been developed in which liquid such as oil that has exuded from the food material and moisture that adheres to the surface of the food material do not stay in the food material. In the invention disclosed in Patent Document 1, water that has flowed out from fresh food is stored in the tray by a plurality of ridges alternately arranged in parallel and a plurality of ridges provided in the groove. In the invention disclosed in Patent Document 2, a bulging portion is formed on the bottom surface of the tray, and when fresh food is placed on the bulging portion, the fresh water oozes out into the water collecting groove existing between the bulging portions. I'm trying to collect water. Further, in the invention disclosed in Patent Document 3, inclined grooves and ribs are alternately formed on the bottom wall of the container, and it is intended to effectively prevent contact between the food material supported by the ribs and water droplets or oil by the inclined grooves. .

  Among each of the above patent documents, Patent Document 1 is designed to capture water in a small pit provided in the groove, but water flows out of the fresh food product exceeding the amount of water that the dent can capture. No consideration is given to how to deal with the case. In addition, the water collecting groove in Patent Document 2 substantially refers to the bottom surface of the tray, and is described so that the first and second water collecting grooves exist. This is the bottom. Therefore, there is a problem that the collected water can freely move in the water collecting groove and cannot be captured in a stable state. Moreover, in patent document 3, although a water droplet and an oil component are isolate | separated from a foodstuff with an inclination groove | channel, and it collect | recovers in a fixed place, the inclination groove | channel starts from the same height as a rib, or the same plane as a rib. As a result, if the target to be separated from the food is high-viscosity oil or sauces, it will stay in the vicinity of the starting point of the inclined groove and will remain so that it cannot be recovered as expected. is doing.

  The present invention solves the above-mentioned problems of the prior art at a stretch, and effectively separates liquid that has exuded from the inside, especially excess oil adhering to the surface or highly viscous sauce, especially in the case of cooking ingredients. It is an object of the present invention to provide a tray container having a structure in which the recovered liquid or oil is not reattached to the food.

  The present invention has improved the structure of the bottom of the tray container in order to achieve the above-described object. Specifically, a tray container having wall portions on four sides, a portion excluding the four rounds on the bottom surface of the tray container is defined as a raised portion, and a plurality of rising ribs parallel to the raised portion, and these ribs Each has a groove between them, and at least both sides of these grooves are inclined grooves with a gradient, and the lowest part of the inclined grooves is communicated with an oil sump provided in a part of the four circumferences of the bottom surface. Means were used. In this configuration, the rib functions as a place where the food is displayed, and the inclined groove has a function of capturing oil from the food and guiding the oil to the oil pool along the gradient.

  Since the present invention adopts the above means, for example, even when displaying tempura or fried foods rich in oil, if the food is placed on the rib, the oil is captured in the inclined groove, According to the gradient, the oil is led to the oil pool, so that the optimum state can be maintained until the food purchaser provides the meal.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of a tray container of the present invention. The tray container basically includes a bottom surface 1 and a wall portion 2 rising from the periphery of the bottom surface. However, the configuration of the wall portion 2 is not particularly limited, and the tray container is required to rise from the bottom surface 1. For example, a lid (not shown) may be combined, or a known lid may be employed within a range sufficient to shield the opening with a resin film.

  In FIG. 1, 3a and 3b are horizontal ribs provided in the rising direction at the same height, 4a and 4b are inclined grooves each having a gradient in the direction of the arrow, and in FIG. A gradient in the opposite direction is given with the part as a boundary. FIG. 2 is an end view showing the relationship between the rib 3 and the inclined groove 4, but does not exactly match the bottom shape of FIG. 1. The configuration shown in FIG. 2 is mainly based on the fact that the ribs 3 and the inclined grooves 4 can be easily grasped in the waveform, and should be understood for that purpose. FIG. 2 shows that the entire bottom surface 1 of the tray container except for the four rounds is a raised portion, and ribs 3a and 3b and inclined grooves 4a and 4b are provided on the raised portion. . Reference numeral 5 denotes an oil sump for capturing the oil and the exudate of the food material that have continued to the lowest portion 6 of each of the inclined grooves 4a and 4b and have flowed down along the gradient of the inclined grooves 4a and 4b. FIG. 3 shows the inclined groove 3a appearing in the right half of FIG. 1, and FIG. 4 shows the inclined groove 3b appearing in the left half of FIG. In both cases, the details are partially omitted as in the case of FIG. As shown in the figure, the oil reservoir 5 is formed with fine ribs 7 perpendicular to the length direction. This prevents the captured oil from moving easily inside the oil reservoir 5, and the bottom surface. Although it is for ensuring the intensity | strength of 1 whole, it may abbreviate | omit. The heights of the ribs 3a and 3b are preferably all the same from the standpoints of ensuring strength and aesthetics. However, the unevenness that repeatedly appears due to the ribs 3 and the inclined grooves 4 is uneven in the tray container. If the depth of the bottom surface 1 is emphasized and the volume feeling of the foodstuff displayed on the surface of the rib 3 can be produced, it is not necessary to make the height of each rib 3 completely correspond. About this, although it is a matter which can be selected suitably, what is necessary is that the inclined groove 4 partitioned by the rib 3 is deep enough to capture oil and the like, and the depth due to the unevenness is visible, There is no particular question.

  In the present embodiment, the oil sump 5 is L-shaped with the diagonal face of the rectangular bottom surface 1 being sandwiched therebetween, but does not necessarily extend to the short side portion 5a. In short, as long as the oil component and the like exuded from the food can be sufficiently captured by the oil sump 5, it can be constituted by only a straight portion.

  In FIG. 1, 8 is a flat part provided at the highest part side of each of the inclined grooves 4a and 4b, and a pillow part 9 bulging in an arch shape is provided. The pillow portion 9 is for placing a pouch such as a sauce, but also functions as a stopper when the food material is moved, so that the food material does not come into contact with the pouch and become oily. And if necessary, the sauce or juice enclosed in the pouch is placed in this part to prevent it from being soiled with exuded oil. Reference numerals 10 are provided on the outer peripheral side of the flat portion 8, and are partition portions having a height substantially equal to the height of the flat portion 8, and function as a place for placing a pouch such as a source in cooperation with the flat portion 8. The partition 10 also has a function of partitioning both ends of the oil sump 5. Similarly to the rib 7 provided in the oil sump 5, the partition part 10 may be provided with a rib 11 as necessary.

  In the tray container of the above-described embodiment, foods containing oil mainly such as fried foods and fried foods, and vegetable soaking in which the internal liquid is inevitably exuded as time passes are displayed. Then, if necessary, the pouch of the sauce is placed on the flat part 8 and the partition part 10, and the end part and the mouth part of the pouch are positioned on the pillow part 9. If it does in this way, the oil etc. which exuded from the foodstuff will flow into inclination groove 4a * 4b, without the foodstuff itself absorbing again, and will flow into oil sump 5 along the inclination. Moreover, in this embodiment, the oil sump 5 and the flat part 8 and the partition part 10 which are places where a pouch is placed are clearly separated, and even if the container is shaken during transportation, the captured oil content contaminates the pouch. Can be avoided. In this way, the food material remains in an appropriate state until before the meal. In the present embodiment, the inclined direction of the inclined grooves 4a and 4b is reversed in the left and right half of the tray container, and the installation locations of the oil sump 5, the flat portion 8, the partitioning portion 10 and the like are made symmetrical accordingly. Yes. By doing in this way, even if there is much oil exuded from a foodstuff, it does not accumulate in part, and it can avoid the overflow of an unnecessary oil.

  In the embodiment shown in FIG. 1, the tray container is described as a horizontally long rectangle. However, the relationship between the rib 3 and the inclined groove 4 is not necessarily rectangular, and the bottom surface may be square, circular, or elliptical. Needless to say, the present invention can be widely applied without being limited by its shape.

  FIG. 5 shows an embodiment different from the inclined grooves 4a and 4b shown in FIGS. 3 and 4, and the gradient is symmetrical in the left-right direction on the drawing with the center of the drawing being the highest. It is a gable shape provided with inclined grooves 4c and 4d. In addition, as a form of an inclined groove | channel, it may change to an arch shape or a elliptical arc shape where the center part becomes the highest instead of a gable shape. By comprising in this way, an oil component flows down in both directions. In particular, in the case of a gable, the angle of the gradient is larger than the gradient of the inclined groove shown in FIGS. 3 and 4, so that the oil that has flowed into the inclined groove can flow more easily, and the oil has a high viscosity. However, it can be effectively captured in the oil sump without remaining in the inclined groove.

  In the present embodiment, only the tray container main body has been described. However, as a container to which the present invention is applied, even if the tray main body is shielded by a separate lid, the tray container and the lid are connected by a hinge. Of course, it may be a food pack.
