Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food packaging container used for containing foods, particularly salads and cut fruits.

[0002]

2. Description of the Related Art Salads, cut fruits, etc., which are packaged in plastic containers, are displayed on shelves for sale at the food counters of supermarkets and convenience stores. These salads and cut fruits are often placed in transparent containers so that the customer can judge the contents.

[0003]

[Problems to be Solved by the Invention] Salads and cut fruits contain a large amount of water, and when they are displayed for several hours, water flows out and collects at the bottom of the container. There was a problem in that the water accumulated at the bottom of the container was visible from the outside and was not good in appearance.

In view of the above problems, the present invention is to provide a food packaging container that does not affect the appearance even if water such as salad or cut fruits accumulates at the bottom of the container.

[0005]

In order to solve the above problems, the present invention provides a plastic food packaging container with continuous opaque or translucent printing on the bottom surface of the container body and the lower portion of the surrounding peripheral wall surface. The processed food packaging container was used. The opaque or semi-transparent print is preferably colored in the same color system as the color of water emitted from the stored food. By doing this, opaque or semi-transparent printing is applied even if water such as salad or cut fruit in the container starts to flow out and accumulates at the bottom of the container, so hide the water accumulated at the bottom from the outside. To be able to
Further, since the upper part of the peripheral wall and the lid are left transparent, the contents can be confirmed from the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a side view of the container body of FIG. 1, and FIG.
2 shows a cross-sectional view of the container body of FIG.

Although the food packaging container 1 is not limited to the structure shown in the embodiment, it is provided with a container body 2 and a lid 3 in FIGS. 1 to 3. Both bodies can be molded by a thermoforming method such as compressed air or vacuum molding using an appropriate plastic such as stretched polyester, polypropylene, polyethylene terephthalate, and amorphous polyethylene terephthalate.

The container main body 2 has a peripheral wall 5 which rises upward at an appropriate height around a bottom surface 4 having a substantially circular shape in plan view to form an internal storage portion 6. The upper portion of the peripheral wall 5 is folded back outward, and the peripheral edge thereof is folded back downward to form an engaging portion 7 which can be engaged with the lid 3. Further, a main body opening piece 8 for extending the container main body 2 and the lid body 3 is provided on a part of the outer periphery of the engaging portion 7 so as to extend outward.

A substantially central portion of the bottom surface 4 is a mounting portion 9 which is bulged upward in a substantially octagonal shape, and the periphery thereof is formed as a water receiving portion 10. The inner surface 10a and the outer surface 1 of the water receiving portion 10 are formed.
0b has a shape in which a plurality of convex ridges and concave grooves are alternately formed radially outward. The bottom surface 4 is printed in white, and the bottom surface 4 of the peripheral wall 5 is also printed in white at an appropriate height so that it is difficult to see the inside from the outside. On the inner surface 5a and the outer surface 5b of the peripheral wall 5 which have been printed to an appropriate height, a plurality of convex ridges and concave grooves which are raised or depressed in the circumferential direction are alternately formed.

The lid 3 has a substantially circular shape in a plan view, a substantially central portion of which is a flat surface, and an outer edge of the lid 3 is engaged with an engaging portion 7 of the container body 2 having a substantially U-shaped cross section. A stop 11 is provided. Further, a lid opening piece 12 is provided on a part of the outer circumference of the locking portion 11 so as to make it easy to open the lid 3.

The food packaging container 1 thus formed is
When displayed in the store, the storage portion 6 of the container body 2 is packed with salad or cut fruit, and the engagement portion 7 of the container body 2 and the locking portion 11 of the lid body 3 are engaged and covered. It is displayed on shelves. In addition, when the food packaging container 1 is displayed for several hours, water such as salad and cut fruits flows out and starts to accumulate on the bottom surface 4. Conventionally, since a transparent container is often used as the container body 2,
The water that had begun to accumulate on the bottom surface 4 was visible from the outside, which did not look good and gave the customer discomfort.

However, in the present invention, white printing is performed from the bottom surface 4 and the bottom surface 4 of the peripheral wall 5 up to an appropriate height to make it opaque, and even if water collects on the bottom surface 4, it is difficult to see from the outside. Even if the water is displayed on the bottom surface 4 for a long time and the water starts to collect on the bottom surface 4, it is not possible for the customer or the like to directly see the water, so that it is possible to prevent discomfort and improve the appearance. At this time,
The height of the printing applied to the peripheral wall 5 is not particularly limited, but it is changed depending on the contents put in the food packaging container 1, and if the contents have a lot of water such as cut fruits, set it high, and the water content such as salad may be too high. It is preferable to set low values for those that do not exist. In addition, although the printing is performed in white in the above embodiment, the printing is not limited to this color, and may be colored semitransparently instead of opaque. Further, the water flowing out from the salad or the cut fruit put in the storage section 6 may be used. You can make it even more attractive by matching it with the color of.

A loading section 9 is provided on the bottom surface 4, and when the storage section 6 is filled with salad or cut fruits, the contents such as salad and cut fruits are loaded on the loading section 9, and the salad and cut fruits are loaded. Since the water flowing out from the pool will be collected in the water receiving part 10 provided around it, it is less likely that the water flowing out will come into direct contact with the contents such as salad and cut fruits, and the salad and cut fruits themselves will collect. It can be prevented from being damaged by moisture. The upper surface of the mounting portion 9 is transparent, and the outer surface 1 of the water receiving portion 10 is
It is also possible to make only 0b and the peripheral wall 5 opaque or semi-transparent, so that the contents can be seen through from the bottom direction. The above-mentioned placing portion 9 and the water receiving portion 10 do not necessarily have to be provided, but it is preferable to provide because of the above effects, and the shape when provided is not limited to that shown in the drawing. Instead, the mounting portion 9 may be circular or square.

On the inner surface 10a of the water receiving portion 10 and on the lower side of the inner surface 5a of the peripheral wall 5, raised or depressed convex ridges and concave grooves are alternately formed, so that the water accumulated in the water receiving portion 10 is concave. It will accumulate in the groove. This prevents water from flowing even if the food packaging container 1 is slightly tilted. Therefore, even if the customer picks up the food packaging container 1 and tilts it slightly, the water does not flow. Moisture in is less visible.

The outer surface 10b of the water receiving portion 10 is also provided with a plurality of convex ridges and concave grooves so as to reinforce and also serve as an anti-slip when displayed on a shelf or the like at the time of sale. Even if it shakes, it is difficult to remove. Further, a plurality of convex ridges and concave grooves are provided on the outer surface 5b of the peripheral wall 5 near the lower side, so that when the food packaging container 1 is picked up, it serves as a slip stopper and is easy to hold. The inner surface 10a and the outer surface 10b of the water receiving portion 10 and the inner surface 5 of the peripheral wall 5
It is preferable that the convex peaks and concave grooves formed on a and the outer surface 5b are provided as necessary.
