Description

  The present invention relates to a packaging container made of foamed resin suitable mainly for storage and shipping of shellfish such as salmon and other seafood.

  Foamed resin containers are lightweight and have excellent heat insulation and buffering properties, so they are widely used for the storage and shipping of various seafood, such as packaging for shipping salmon. .

  For example, when boiled and cooled salmon or frozen salmon is stored and shipped in a packaging container, the snow crab male, which is a high-quality food, has a relatively large torso portion including the shell and has a large overhanging foot. One container or several cups of potatoes are stored in one container, but the female moth, commonly called Sekogani, is considerably smaller (about 1/2) than the male shark, so in one packaging container, For example, 5 to 15 cups of candy are stored and shipped, and are often displayed while being stored in the container at a retail store or the like.

  In this case, the bag of the packaging object is stored side by side in the container in the front, rear, left, and right directions, but is only placed on the flat bottom in the container, and is stored by vibration during transportation. The bag is easy to move and the storage state is easily disturbed. In addition, when it is displayed in a store or the like while being stored in a container, it is difficult to see from the upper front, and the appearance is not good.

  Conventionally, as a container for storing a large bag, a container made of foamed resin has been proposed as disclosed in Patent Document 1 so that long legs do not jump out, but long legs protrude outside the container to the last. It is intended to prevent movement, and does not restrict movement due to vibrations or the like during transportation. In particular, there is no consideration for movement restriction when a plurality of baskets are stored side by side.

  In addition, as a container for the bag, in order to restrict the movement of the bag due to vibration during transportation, a container that presses the body part of the bag from above has also been proposed (Patent Document 2). When storing a relatively large bag, the movement is restricted by sandwiching the body part from above and below. There is no description about holding.
