Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for storing foodstuffs and the like and displaying them on a mounting base such as a table or a display shelf.

At retail stores such as convenience stores and supermarkets, packed lunches, side dishes, and the like are sold in resin containers. Such containers are often made from a transparent resin sheet so that the contents can be checked. Since the opening of the container body is generally formed in a horizontal plane, it is necessary to look into the container from above in order to check the contents. Therefore, if consumers do not have the desire to purchase, the product will not be noticed and the product will lack appeal.

Therefore, for example, in the following Patent Document 1, an opening for storing food inside, a fitted portion erected on the periphery of the opening, and an upper end of the fitted portion extending to the outer peripheral side and a transparent lid that covers the opening of the container body, and with the lid attached to the container body, a part of the bottom of the container body and the flange of the container body A food container whose center of gravity is positioned between the vertical direction of a part of the bottom and the vertical direction of a part of the flange when placed on a horizontal surface so that the two parts are in contact with each other. is being developed. This container can be placed vertically to show the contents.

Further, in Patent Document 2 below, a flange portion is provided toward the outside of the rim of the container body, and a side wall that also serves as a bottom surface having corner wall surfaces at both ends and a bottom surface having a convex portion that protrudes inward of the container body. When the side wall that also serves as the bottom surface is used as the bottom surface, the center of gravity of the container body is located on the opening side of the container body with respect to the normal line from the point of contact between the ground surface and the side wall that also serves as the bottom surface. A container for microwave cooking has been developed, characterized by: This container can be displayed upright so that the contents can be seen, and the product can be appealed to consumers.

As described above, conventional containers are placed vertically and the lid is positioned on the front side to make it easier to visually recognize the contents, thereby appealing to consumers and encouraging them to buy.
However, when foodstuffs and the like are stored and placed vertically, the fitting portion between the lid body and the container body faces the bottom side, so there is a risk of leakage of juice or the like from the foodstuffs. In addition, since there is a risk that the lid may be opened, sellers are reluctant to display the products in a vertical position.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a packaging container that can appeal to consumers the contents even when placed with the bottom portion of the container body as the bottom as usual. Moreover, the packaging container can be placed vertically or otherwise.

A packaging container according to one embodiment of the present invention has a rectangular opening in a container body, a trapezoidal bottom portion with a bottom side facing the front side of the container, and a It is characterized in that it is inclined upward from the front side toward the back side.

By making the opening part inclined in this way, the opening part faces obliquely to the front side, so that when the product is displayed in a retail store, consumers can check the contents without looking in from above. This makes it easier for the stored items to catch the eye. In addition, the opening is rectangular and the bottom is trapezoidal, giving the impression of depth when looking into the container through the opening. can promote

In the packaging container of the above configuration, the front side wall surface of the container body inclines outward from the lower edge toward the upper edge, and the rear side wall surface of the container body inclines inward from the lower edge toward the upper edge. It is tilted so that the upper edge of the rear side wall surface portion is located inside the container with respect to the rear side edge portion of the bottom surface portion. By doing so, the container body is slanted and faces the front side, so that the whole inside of the body can be seen from the opening, and the whole contents can be easily seen, and the desire to buy can be stimulated.

In the packaging container having the above configuration, the rear side wall surface portion of the container body can be formed in a curved shape that protrudes outward from the container. By doing so, it is possible to make the container body appear to expand toward the back side, and to make the container feel as if it has more volume than its actual capacity.

The packaging container of the above configuration can be provided with a lid that can be fitted into the opening of the container body. can be configured to have As a result, even when the lid is closed, the inside of the main body can be easily seen from the top surface, and the contents can be noticed by consumers, thereby making it possible to appeal the product.

The packaging container of the above configuration can be placed vertically with any side wall surface of the container body as the bottom side. In this case, it is preferable to provide at least a rib portion that protrudes outward from the container and is in contact with the mounting table, on the side wall surface portion that becomes the bottom side when the container is placed vertically on the mounting table. In this way, even when the container is placed vertically, the opening can be directed obliquely upward, making it easier for consumers to see the contents. At this time, if a rib portion is provided on the side wall portion on the bottom side so as to be in contact with the mounting table, the rib portion supports the container, so that the container can be placed vertically stably.

The packaging container of the above configuration can be turned upside down on the mounting table with the lid on the bottom side. In this way, the container can be used even when turned upside down, and can be visually recognized from the bottom side.
As described above, the packaging container having the above-described configuration can be used regardless of the configuration of the display shelf, since a plurality of display variations can be selected. Since it is not necessary to prepare a container that matches the shape of each display shelf, it is advantageous in terms of cost and environment.

The skirt portion 34 is provided at an appropriate position with a locking portion 35 projecting inwardly of the container by a predetermined length. The body 3 is adapted to fit over the container body 2 .

The packaging container 1 contains foodstuffs inside a container body 2, is fitted with a lid 3, and is placed on a flat mounting table 4 such as a product shelf or a table as shown in FIG. can be displayed.
When the packaging container 1 is placed on the mounting table 4 and displayed, the lid 3 (opening 26) faces obliquely to the front side, and the contents can be confirmed without the consumer looking in from above. Therefore, the stored items are easy to catch the eye, and the desire to buy can be stimulated.
Since the opening 26 has a substantially rectangular shape and the bottom surface 21 has a trapezoidal shape, when looking into the inside of the container body 2 from the side of the opening 26, an optical illusion gives an illusion of depth, which is larger than the actual capacity. It is recognized as having a sense of volume. Therefore, purchase intention can be promoted. In particular, it is preferable that the lower bottom side of the trapezoidal shape of the bottom surface portion 21 is the front side of the container.
By forming the rear side wall surface portion 23 in a curved shape that bulges outward from the container, the container body 2 appears to expand toward the rear side, thereby making the container feel more voluminous.

By tilting the front side wall surface portion 22 and the rear side wall surface portion 23 toward the front side of the container, the packaging container 1 has the entire container main body 2 facing the front side, and when the inside of the main body 2 is viewed from the opening 26 side, the inside of the main body 2 can be seen from above. You can check the contents at a glance without looking into it. Therefore, the contents can be appealed to consumers.
Further, even if the lid 3 is provided, if the inclination angles of the top surface portion 31 of the lid 3 and the opening portion 26 are set parallel to each other, the contents can be easily recognized visually.

As shown in FIG. 5, the packaging container 1 can also be vertically placed on the mounting table 4 with the rear side wall surface portion 23 on the bottom side. At this time, the container 1 can be stabilized by bringing the rib portion 29 into contact with the mounting table 4 . In FIG. 5, the rear side wall portion 23 is the bottom side, but any of the other side wall portions 22, 24 and 25 can be the bottom side. By placing the container 1 vertically, the lid 3 (opening 26) faces obliquely to the front side, making it easier to visually recognize the contained items and stimulating the consumer's willingness to buy.
Further, if the rear side wall surface portion 23 is formed in a curved shape that bulges outward, even if foodstuffs or the like are accommodated and placed vertically with the rear side wall surface portion 23 on the bottom side, the juices exuded from the foodstuffs will not be absorbed by the rear side wall. It accumulates in the surface part 23 and becomes difficult to leak out.

FIG. 6 shows a modified packaging container 1a, and the lid 3a has a top surface 31a that is flush with the opening 26 of the container body 2 or recessed one step toward the inside of the container from the opening 26. It is as a thing.
By using such a lid 3a, as shown in FIG. 7, the lid 3 can be placed on the mounting table 4 with the lid 3 on the bottom side, and the packaging container 1a can be turned upside down and displayed.

When the packaging container 1a is placed upside down, the bottom part 21 faces obliquely to the front side, so that the contained items can be easily visually recognized in the same manner as described above, and the consumer's willingness to buy can be stimulated.
In this way, the packaging containers 1 and 1a can be used regardless of the form of the mounting table 4 such as a display shelf, with a plurality of display variations available. Since it is not necessary to prepare a container suitable for each mounting table 4, the cost can be reduced, and only one container is required.

The configuration aspects of the above-described embodiments are not intended to limit the present invention, and modifications are possible as long as the technical purpose is shared, and the present invention includes such modifications.
