Description

  The present invention relates to a container for storing and transporting vegetables, fruits and the like, and marine and marine products such as seafood. More specifically, the present invention relates to a container suitable for drainage when draining ice melt water or washing water in a container of contained items.

  Vegetables such as broccoli, fruit and other agricultural products, fish, shellfish, and other marine products that are required to maintain freshness may need to be stored and transported while being cooled with ice. In this case, in the middle of storage and transportation, operations such as removing ice defrost from the container and adding ice as necessary may be performed while the pallet is still stacked. Containers for storing and transporting fish, shellfish, and other fishery products such as turban shells, cold yellowtails, etc. are stored in the container, then poured for water washing to remove dirt and foreign matter, and then the lower or lower part of the container. There are many applications where good drainage and subsequent efficient closure are required, such as draining from the opening and closing the opening (drainage port) before shipping.

  For the purpose of draining melted ice water when transporting broccoli, etc., the bottom of the side wall of the foamed synthetic resin container is provided with a drain hole that expands slightly toward the outside and expands into the hole. A container provided with a resin stopper has been proposed (see Patent Document 1).

In addition, as in Patent Document 1, a water drain hole is provided in the lower portion of the side wall of the foamed synthetic resin container, and the water stop is integrally formed on the inner bottom surface of the container in a severable manner to prevent loss of the foamed synthetic resin stopper. An invention for a plug body has also been proposed (see Patent Document 2).

  However, in the container described above, the drainage and sealing plugs must have a structure that protrudes to the outside of the container. There is always the possibility of unnecessary plug opening due to vibration or other causes, or loss of the plug every time it is opened and closed. Furthermore, if different materials are used for the plugs or the like in order to solve these problems, it is troublesome that they must be separated at the time of recycling. In the industry, these issues have been pointed out for some time, and a solution has been demanded.

The present invention is to solve the above problems and has the following configuration.
That is, 1) providing an opening that extends over the lower portion of the side wall of the container body and the bottom plate, forming an opening / closing lid portion that follows the shape of the opening portion, and opening and closing the opening / closing lid portion; The present invention relates to a cold storage container that enables drainage.
2) The cold storage container according to 1), wherein the shape of the opening is such that a hanging portion is provided on the inner peripheral side of the lower end portion of the side wall, and a protruding portion is provided at a substantially intermediate portion of the thickness of the end portion of the bottom plate. .
3) The cold storage container according to 2), wherein the shape of the opening is such that a hanging portion is provided on the inner peripheral side of the lower end of the side wall.
4) The cold storage container according to 2) or 3), wherein a concave drainage groove is provided from the vicinity of the base end portion of the upper surface of the protruding portion toward the protruding direction.
5) The shape of the opening / closing lid is a shape following the shape of the opening, and can be closed and opened by a fitting structure between the opening and the opening / closing lid, 1) to 4) It relates to a cold storage container.

  Even when the present invention is stacked in the upper and lower stages, or when not stacked, the drainage and the subsequent operation can be performed by simply sliding the open / close lid part left and right without moving the position of the container body. It is possible to provide a container that can be easily closed. Furthermore, since the opening / closing lid part is a part of the container, it can be closed in a watertight or airtight state in a state of being completely fitted in the opening except during drainage, so it is exactly the same as a normal container. Since it does not protrude outward from the main body, there is no possibility of the opening / closing lid part dropping off or losing, since there is no friction between the containers or vibration, contact with the operator, and other concerns. Further, if the container body and the opening / closing lid are formed of the same material, recycling is easy and there is no problem at all.

  The container body of the present invention is preferably formed of a foamed synthetic resin. As the foamed synthetic resin, foamed polystyrene, foamed polyethylene, foamed polypropylene, hard foamed urethane resin, and the like can be used. Among them, foamed polystyrene is preferable.

  The opening of the present invention may be provided on any of the four side walls of the container body, and one or more openings may be provided. When a container main body is a rectangle, it is preferable to provide in a short side wall among four side walls. This is because when arranging a plurality of containers in contact with each other, the long side walls of the container main body are often arranged in contact with each other, so that the short side walls are not in contact with other containers. Therefore, when the opening is provided in the short side wall, it is possible to prevent the other container brought into contact with the water from being disturbed when draining. And it is the most preferable aspect to provide one on each of the two opposing short side walls. This is because the other opening can be used even in a case where one opening is obstructed by another container. In the case where one opening is provided on each of the two opposing short-side side walls, it is preferable to provide the openings diagonally so as to maintain the strength balance of the entire container. Although more than two openings may be provided, the strength of the container tends to decrease.

  Furthermore, since the opening / closing lid portion fits closely to the opening portion of the container body and seals the opening portion, the container can be closed in a watertight manner when the opening / closing lid portion is closed. When closed with a lid, it can be closed airtight like a normal container. With regard to the opening and the opening / closing lid, as a structure that enables good drainage when the closed state of both is released, various devices are required as in the embodiments described later. However, the engaging portion of the both is only required to be able to maintain the watertight or airtight state by some structure, and therefore the structure is not particularly limited. For example, a fitting structure having a general uneven structure may be used.

  Embodiments of the cold container according to the present invention will be described with reference to the accompanying drawings.
