FIELD: packing means, particularly boxes provided with lids or having no lids and adapted for food packing, transportation and storage. ^ SUBSTANCE: a box is produced of flat sheet blank having central rectangular zone, foldable side walls and foldable end walls connected to central rectangular zone through scored fold lines formed in inner side thereof. Corner areas between adjacent walls include foldable tabs divided in pairs by diagonal scored fold lines extending outwards and adapted to fold the tables so that tabs abuts adjacent wall and are connected to them. Pair of folded tabs may be folded against outer surface of adjacent end wall. Handles may be folded around end wall and act as a lever to press two adjacent walls one to another. In that case pair of foldable tabs are activated and handle is used to connect above pair of tabs to outer side. Common thickness thereof, elasticity and distances between tabs are used to provide increased gripping depth, where additional gripper cooperates with handle. Lid has flat main zone and adjacent border members. To create one or several reclosable packing means border members and main zone in one area have through cuts defining hinged score in-between. Hinged score connects ends of above cuts in main area through groove, perforation or similar members. Before hinge function performing through cuts are held along with adjacent lid part by protective band, which may be peeled away or repeatedly connected, or with the use of similar means and/or band comprises several transversal through draining orifices arranged in lower corner area of end walls and used as drainage orifices for molten ice in the case of box usage for packing fish with ice, wherein the box is adapted to transport fish by trackless or marine transport. Box production method is also disclosed. The box may be formed of disposable material. ^ EFFECT: increased stability and sanitary characteristics, possibility of heat insulation, simplified production, reduced manufacturing costs, possibility to obtain ready-to-use blanks, and to form optimally functioning lid if necessary. ^ 17 cl, 26 dwg |
