Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food packaging container used to contain food, particularly salads, cut fruits and the like.
[0002]
[Prior art]
Salads and cut fruits packed in plastic containers are displayed on shelves at supermarkets and convenience stores. These salads and cut fruits are often placed in transparent containers so that customers can judge their 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, the water flows out and collects at the bottom of the container. When placed in a transparent container, the water collected at the bottom of the container is outside. There was a problem that it was visible and was not good looking.
[0004]
In view of the above problems, the present invention is to provide a food packaging container that does not affect the appearance even if moisture such as salad or cut fruit accumulates at the bottom of the container.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a plastic food packaging container, wherein the container body has a substantially circular shape in plan view, and a mounting portion having a substantially central raised portion on the bottom surface, and a water receiver around it. A plurality of ridges and grooves are alternately formed radially on the inner surface of the water receiving portion, and a plurality of ridges and grooves are alternately formed in the circumferential direction on the inner surface of the lower peripheral wall surface. The food packaging container was formed and continuously opaque or translucent printed on the bottom surface and the lower peripheral wall surface. The opaque or translucent printing is preferably colored in the same color system as the color of moisture from the stored food.
By doing so, even if moisture such as salad or cut fruit in the container flows out and begins to accumulate at the bottom of the container, opaque or translucent printing is applied, so that moisture accumulated at the bottom is hidden from the outside In addition, the upper part of the peripheral wall and the lid are kept transparent so that the contents can be confirmed from the outside.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
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. 3 is a cross-sectional view of the container body of FIG.
[0007]
Although the food packaging container 1 is not limited to the structure shown in embodiment, in FIG. 1 thru | or FIG. 3, the container main body 2 and the cover body 3 are provided. Both bodies can be formed by a thermoforming method such as compressed air or vacuum forming using an appropriate plastic such as stretched polyester, polypropylene, polyethylene terephthalate, and amorphous polyethylene terephthalate.
[0008]
The container body 2 has an inner storage portion 6 formed by raising a peripheral wall 5 at an appropriate height upward around a bottom surface 4 having a substantially circular shape in plan view. The upper portion of the peripheral wall 5 is folded outward, and the peripheral edge thereof is folded downward to form an engaging portion 7 that can be engaged with the lid 3. Further, a main body opening piece 8 for facilitating opening of the container main body 2 and the lid 3 is extended outward from a part of the outer periphery of the engaging portion 7.
[0009]
A substantially central portion of the bottom surface 4 is formed with a mounting portion 9 raised upward in a substantially regular octagonal shape, and its periphery is formed as a water receiving portion 10. The inner surface 10 a and the outer surface 10 b of the water receiving portion 10 are formed in the outer direction. A plurality of convex ridges and concave grooves are alternately formed radially. The bottom surface 4 is printed in white, and is also printed in white even at an appropriate height from the bottom surface 4 of the peripheral wall 5, making it difficult to see the inside from the outside. On the inner surface 5a and the outer surface 5b up to an appropriate height on which the peripheral wall 5 has been printed, a plurality of convex ridges and concave grooves raised or depressed in the circumferential direction are alternately formed.
[0010]
The lid body 3 has a substantially circular shape in plan view, has a substantially central plane, and an engaging portion 11 that engages with an engaging portion 7 of the container body 2 having a substantially U-shaped cross section that opens downward at the outer edge. Is provided. Further, a lid opening piece 12 for facilitating opening of the lid 3 is extended outwardly at a part of the outer periphery of the locking portion 11.
[0011]
When the food packaging container 1 formed in this way is displayed at the storefront, the storage unit 6 of the container body 2 is filled with salad, cut fruit or the like, and the engagement portion 7 of the container body 2 and the lid 3 are engaged. The stopper 11 is engaged and covered and displayed on a shelf or the like.
When the food packaging container 1 is displayed for several hours, moisture such as salad or cut fruit 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 moisture that has started to accumulate on the bottom surface 4 is visible from the outside, which does not look good and gives the customer an unpleasant feeling.
[0012]
However, in the present invention, white printing is performed from the bottom surface 4 and the bottom surface 4 of the peripheral wall 5 to an appropriate height to make it opaque, and even if moisture accumulates on the bottom surface 4, it is difficult to see from the outside. Even if the display starts and moisture begins to accumulate on the bottom surface 4, since moisture cannot be seen directly by the customer or the like, discomfort can be eliminated and the appearance can be improved.
At this time, the height of printing applied to the peripheral wall 5 is not particularly limited, but it is changed depending on the contents to be put in the food packaging container 1 and is set to be high for the contents that have a lot of moisture such as cut fruits, salads, etc. It is preferable to set a low moisture content.
In the above embodiment, printing is performed in white. However, the printing is not limited to this color, and may be colored translucently instead of being opaque. Further, the moisture flowing out from the salad or cut fruit put in the storage unit 6 If it is matched with the color, it can be further improved in appearance.
[0013]
The bottom 4 is provided with a placement portion 9, and when filling the storage portion 6 with salad or cut fruit, the contents such as salad or cut fruit are placed on the placement portion 9 and flow out of the salad or cut fruit. Since the collected water will be collected in the water receiving section 10 provided around it, it will be less likely to come into direct contact with the flowed-out water and the contents such as salad and cut fruit, and the salad and cut fruit itself will be damaged by the accumulated water. Can be prevented.
In addition, the upper surface of the mounting portion 9 can be transparent, and only the outer surface 10b of the water receiving portion 10 and the peripheral wall 5 can be opaque or translucent, so that the contents can be seen through from the bottom.
The placement portion 9 and the water receiving portion 10 are not necessarily provided, but are preferably provided because of the above effects, and the shape when provided is not limited to that shown in the figure. Alternatively, a circular or quadrangular mounting portion 9 may be used.
[0014]
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 ridges and depressions and concave grooves are alternately formed, and the water accumulated in the water receiving portion 10 is accumulated in the concave grooves. It will be. This prevents moisture from flowing even if the food packaging container 1 is tilted slightly. For this reason, even if the customer picks up the food packaging container 1 and tilts it slightly, the moisture does not flow. Moisture in water is less visible.
[0015]
The outer surface 10b of the water receiving portion 10 is also provided with a plurality of ridges and grooves, and when it is sold, it plays a role of anti-slip when displayed on a shelf, even if the shelf is shaken by vibration etc. It is hard to fall off.
Further, the outer surface 5b closer to the lower side of the peripheral wall 5 is provided with a plurality of ridges and grooves, so that when the food packaging container 1 is picked up, it plays a role of preventing slipping.
It is preferable to provide the protrusions and grooves formed on the inner surface 10a and outer surface 10b of the water receiving portion 10 and the inner surface 5a and outer surface 5b of the peripheral wall 5 as necessary.
[0016]
【The invention's effect】
The present invention provides a food packaging container by applying opaque or translucent printing continuously to the bottom and lower part of the peripheral wall surface of a plastic food packaging container, and further coloring the same color as the color of moisture from the stored food. Even if the water flowing out from the salad or cut fruit collected inside accumulates at the bottom, it becomes difficult to see from the outside, so when selling it should be good looking even if it is displayed on a shelf for several hours it can.
