Abstract
Abstract A packing container for transport of products giving off moisture, e.g. fresh iced fish products and fresh meat products, comprising a box that opens upwards and is made from a liquid tight material with a lid and a bottom having drainage openings. The bottom is raised in relation to the lower edges of the side walls of the box for forming a chamber that is open downwards where a moisture absorbent is placed. The chamber may be closed with a lid being identical with said upper lid. The lids are provided with annular grooves on both side faces for engagement with projections on the upper and lower edges of the box side walls. Furthermore, the annular grooves in the lower lids are intended for engagement with packing containers that are open upwards when the packing containers are piled on top of each other to prevent lateral sliding. To achieve additional safeguarding against seepage of moisture the packing container is placed in an outside packing made from watertight carboard in the shape of a sleeve with leakage proof end closures.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
A packing assembly for storage and transport of fresh food products which give off moisture, such as fresh iced fish product and fresh meat products and the like comprising a box opening upwards and made from a liquid tight material with an upper lid, side and end walls, and a double bottom comprising an upper bottom member with drainage openings and a lower bottom member, and a moisture absorbent provided in a chamber between said bottom members where said absorbent is kept in place and is protected against mechanical strain, the upper bottom member of the box being raised in relation to lower edges of the side and end walls of the box to form said chamber having its opening facing fownward for insertion of a moisture absorbent, and the lower bottom member consisting of a chamber lid for closing said chamber with its content of absorbent, and said chamber lid being identically shaped with the upper lid for the box, and said side and end walls having lower and upper rims, and said lids being provided with an annular groove at one end face for engagement with the lower and upper rims of the box side and end walls.
