Description

The present invention relates to a molded container obtained by molding a synthetic resin sheet, and mainly relates to a tray container having a structure in which the food material itself can be displayed without being soaked in food oil or juice exuded from the placed cooking food material. be.

Traditionally, tray containers made of synthetic resin sheets have been widely used when displaying and selling processed foods such as tempura and fried foods at supermarkets. And these containers are generally shielded by a similarly molded lid on the tray container for hygiene. Of course, a form in which the opening of the tray container is covered with a resin film or the like may be adopted without adopting a lid.

By the way, the simplest structure of the bottom surface of the tray container is a bottom having a flat surface, but in order to secure the overall strength, ribs are first adopted on the bottom surface and the wall surface. Subsequently, in recent years, with the diversification of this type of tray container, a tray container having a bottom structure according to the characteristics of the contents to be stored inside has been developed. The direction of such development is the same for the tray container using the non-foamable resin sheet and the tray container using the foamable resin sheet.

Further, various configurations have been developed in which liquids such as oil exuded from the food material and water adhering to the surface of the food material do not stay in the food material. In the invention shown in Patent Document 1, a plurality of ridges in which water discharged from fresh food is alternately arranged and a plurality of pits provided in the concave groove are used to collect the water in the tray. In the invention shown in Patent Document 2, a bulging portion is formed on the bottom surface of the tray, and when the fresh food is placed on the bulging portion, the fresh food exudes into the water collecting groove existing between the bulging portions. I'm trying to collect water. Further, in the invention shown in Patent Document 3, inclined grooves and ribs are alternately formed on the bottom wall of the container, and the inclined grooves are intended to effectively prevent contact between the food material supported by the ribs and water droplets or oil. ..

Of the above-mentioned patent documents, Patent Document 1 is designed to capture water in a small concave jar provided in the concave groove, but water has flowed out from the fresh food product in excess of the amount of water that can be captured by the concave jar. No consideration is given to how to deal with the case. Further, the water collecting groove of Patent Document 2 substantially refers to the bottom surface of the tray, and it is described that the first and second water collecting grooves exist, but the water collecting grooves are substantially the same plane. The bottom of the eggplant. Therefore, there is a problem that the collected water can move freely in the catchment ditch and cannot be captured in a stable state. Further, in Patent Document 3, water droplets and oil are separated from food by an inclined groove and collected in a certain place. The inclined groove starts from the same height as the rib or the same plane as the rib. Then, if the object to be separated from the food is highly viscous oil or sauce, the viscosity is high near the start point of the inclined groove, so that it stays and cannot be recovered as expected. is doing.

The present invention solves the problems of the above-mentioned conventional techniques at once, and effectively separates the liquid exuded from the inside, the excess oil adhering to the surface, the highly viscous sauce, etc., especially in the case of cooking foods. However, the purpose is to provide a tray container having a structure in which the recovered liquid or oil does not reattach to the foodstuff.

The present invention has improved the structure of the bottom of the tray container in order to achieve the above-mentioned object. Specifically, it is a tray container having walls on four circumferences, and the portion of the bottom surface of the tray container excluding the four circumferences is a raised portion, and a plurality of parallel ribs rise from the raised portion, and between these ribs. Has grooves having a depth corresponding to the surface of the raised portion, and has inclined grooves on both sides of these grooves , and the lowest portion of the inclined groove is at least one of the four circumferences of the bottom surface. It communicates with an oil pool provided in the portion, and this oil pool has a depth reaching the bottom surface from the lowest portion of the inclined groove , is orthogonal to the oil pool in the length direction, and is not different from the rib. The means of further providing another continuous rib was used. In this configuration, the rib functions as a place for displaying foodstuffs, and the inclined groove has a function of capturing oil and the like from the foodstuff and guiding the oil content to the oil pool along the gradient.

Since the above means is adopted in the present invention, for example, even when displaying tempura or fried foods rich in oil, if the food is placed on the ribs, the oil is captured in the inclined groove. Since the oil is guided to the oil pool according to the gradient, it has become possible to maintain the optimum state until the purchaser of the food is served for 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 the tray container of the present invention. The tray container is basically composed of a bottom surface 1 and a wall portion 2 rising from the periphery of the bottom surface, but the configuration of the wall portion 2 is not particularly limited, and it is necessary to stand up from the bottom surface 1. For example, a known lid can be used in combination with a lid (not shown) or to the extent sufficient to shield the opening with a resin film.

In FIG. 1, 3a and 3b are ribs provided horizontally at the same height in the rising direction, and 4a and 4b are inclined grooves having a gradient in the arrow direction, respectively. In FIG. 1, the center of the tray container in the longitudinal direction. A gradient in the opposite direction is given with the part as the 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 surface shape of FIG. The configuration shown in FIG. 2 is mainly for easily grasping that the ribs 3 and the inclined grooves 4 appear alternately in a waveform, and should be understood for that purpose. From FIG. 2, it is shown that the bottom surface 1 of the tray container has the entire portion excluding the four circumferences as a raised portion, and the ribs 3a and 3b and the inclined grooves 4a and 4b are provided in the raised portion. .. Reference numeral 5 is an oil pool that is continuous with the lowest portion 6 of the inclined grooves 4a and 4b, respectively, and for capturing the oil content that has flowed down along the gradient of the inclined grooves 4a and 4b and the exudate of the food material. 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. 1, but FIGS. 3 and 4 show. As in the case of FIG. 2, some details are omitted in both cases. As shown in the figure, fine ribs 7 are formed in the oil sump 5 at right angles to the length direction, which prevents the captured oil and the like from easily moving inside the oil sump 5 and the bottom surface. 1 This is to ensure the overall strength, but it may be omitted. It is preferable that the heights of the ribs 3a and 3b match all the heights from the viewpoint of ensuring strength and aesthetics, but the unevenness that repeatedly appears due to the ribs 3 and the inclined groove 4 of the tray container. It is not necessary to completely match the heights of the ribs 3 as long as the depth of the bottom surface 1 can be emphasized and the volume of the foods displayed on the surface of the ribs 3 can be produced. This is a matter that can be appropriately selected, but 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 unevenness can be visually recognized. There is no particular question.

In the present embodiment, the oil pools 5 are L-shaped with the diagonal of the bottom surface 1 of the rectangle sandwiched between them, but they are not necessarily extended to the short side portion 5a. In short, if the oil that exudes from the food can be sufficiently captured by the oil sump 5, it is possible to configure only the linear portion.

In FIG. 1, reference numeral 8 denotes a flat portion provided on the highest portion side of the inclined grooves 4a and 4b, respectively, and an arch-shaped bulging pillow portion 9 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 moves, so that the food material does not come into contact with the pouch and become oily. And if necessary, the sauce and juice enclosed in the pouch are placed in this part so that it will not get dirty with exudated oil. Each of the 10 is provided on the outer peripheral side of the flat portion 8, is a partition portion having a height substantially equal to the height of the flat portion 8, and functions as a place for placing a pouch such as a source in cooperation with the flat portion 8. It also has a function of partitioning both ends of the oil pool 5 by the partition portion 10. The partition portion 10 may also be provided with the rib 11 as needed, similar to the rib 7 provided in the oil sump 5.

The tray container of the above-described embodiment mainly displays foods containing oil such as fried foods and fried foods, and soaked vegetables in which the liquid inside is inevitably exuded with the passage of time. Then, if necessary, the pouch of the sauce is placed on the flat portion 8 and the partition portion 10, and the end portion and the mouth portion of the pouch are positioned on the pillow portion 9. In this way, the oil and the like exuded from the food material flows into the inclined grooves 4a and 4b without being absorbed again by the food material itself, and flows into the oil sump 5 along the inclination. Further, in the present embodiment, the oil pool 5 and the flat portion 8 and the partition portion 10 where the pouch is placed are clearly separated, and even if the container shakes during transportation, the captured oil stains the pouch. Can be avoided. In this way, the ingredients are maintained in proper condition until before meals. In the present embodiment, the inclined directions of the inclined grooves 4a and 4b are reversed in the left-right half of the tray container, and the installation locations of the oil pool 5, the flat portion 8, the partition portion 10, etc. are made symmetrical correspondingly. There is. By doing so, even if there is a large amount of oil exuding from the food material, it will not be unevenly accumulated in a part of the food, and unnecessary overflow of oil can be avoided.

In the embodiment shown in FIG. 1, the tray container is described as a horizontally long rectangle, but the relationship between the rib 3 and the inclined groove 4 does not have to be rectangular, and the bottom surface may be square, circular, or elliptical. Needless to say, it can be widely applied regardless of its shape.

FIG. 5 shows an embodiment different from the inclined grooves 4a and 4b shown in FIGS. 3 and 4, in which the central portion of the drawing is set to the highest position and the gradient is symmetrical in the left-right direction on the drawing. It is a gable-shaped structure provided with inclined grooves 4c and 4d having. The shape of the inclined groove may be an arch shape or an elliptical arc shape in which the central portion is the highest instead of the gable shape. With this configuration, the oil flows down in both directions. In particular, in the case of a gable shape, the angle of the gradient becomes larger than the gradient of the inclined groove shown in FIGS. However, it can be effectively captured in the oil pool without remaining in the inclined groove.

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