[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container.

[0002]

2. Description of the Related Art Conventionally, there are various types of packaging containers using a synthetic resin foam board as a peripheral frame, but the peripheral frame has a rectangular shape for convenience in manufacturing. There are also many that the peripheral frame is formed in a tapered shape, but the bottom plate is solidly attached below the peripheral frame, or the bottom plate is fitted in the groove of the peripheral frame and floated inward. Was something.

[0003] However, the bottom plate of the solid-attached structure must be combined with a non-foamed resin sheet which is easily heat-fused so as to sufficiently withstand the weight of the content. In this case, it is necessary to form a deep groove so that the bottom plate does not come off from the groove of the peripheral frame and increase the fitting length with the bottom plate. Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a packaging container in which the bottom plate is hard to be detached even if the weight of the contents is applied to the bottom plate.

[0004]

A packaging container according to the present invention, which can achieve the above object, is made of a synthetic resin foam board, and is formed by forming a peripheral side frame with a side material which gradually expands in a tapered shape. Attach the bottom plate made of a non-foamed or foamed sheet with leg plates folded at the position of the peripheral part wider than the lowermost part of the side frame along the tapered lower part of the peripheral frame, and part of the leg plate below the peripheral frame. It is characterized by being protruded in the form of a leg.

[0005]

According to the present invention, the peripheral frame is formed of a tapered side member which gradually expands upward because the peripheral frame is formed as described above, so that the peripheral frame is wider than the lowermost portion of the peripheral frame. The bottom plate with the leg plate with the peripheral part folded is stopped at the lower position of the tapered side material only by dropping from above, it is adhered at that position, and a part of the leg plate is projected from the lower part of the peripheral frame into a leg shape. The bottom plate is wider than the bottom of the peripheral frame even if the weight of the contents is applied to the bottom plate. The content can be supported without any.

[0006] In addition, with a unique structure in which a part of the leg plate is exposed from below the peripheral frame, the peripheral frame does not come into contact with the mounting surface, and the display format is improved.

[0007]

Next, an embodiment of the present invention will be described below with reference to the drawings. 1 is made of a synthetic resin foam board such as expanded polystyrene (including a sheet-like slightly thin case),
A peripheral side frame 1 formed by four side members 10 gradually expanding upward in a tapered shape is shown. Reference numeral 2 denotes a bottom plate having a peripheral portion 20 wider than the lowermost portion of the peripheral side frame 1, and the bottom plate 2 integrally has a leg plate 21 bent at the position of the peripheral portion 20. The bottom plate 2 is adhered along the tapered lower portion of the peripheral frame 1 and a part 22 of the leg plate 21 is provided in a leg-like manner.

The side member 10 constituting the peripheral side frame 1 has a wood-grained pattern formed by a laminated film or the like laminated on the surface.
Both sheets are formed in the same direction. Further, four leg plates 21 of the bottom plate 2 are cut off at corners.

[0009]

[Effect of the Invention] The packaging container according to the present invention as described above has a peripheral portion 20 of the bottom plate 2 even if the weight of the contents is applied to the bottom plate 2.
Is wider than the lowermost end of the peripheral frame 1, so that it is securely stopped using the taper without fear of falling below it.
The bottom plate 2 can be used without fear of detachment.

Further, a part 22 of the leg plate 21 has a leg-attached structure exposed from below the peripheral frame 1, so that the peripheral frame 1 does not come into contact with the mounting surface, and the display appearance is also improved. Further, since the bottom plate can be fixed simply by dropping and attaching the bottom plate with the upper leg plate to the peripheral frame until it stops, there is a great advantage that it can be easily manufactured.
