Abstract
Abstract Pallet consisting of several base members, which can have recesses for forks of a fork lift. The base members have holes perpendicular to the length of the members distributed along and closely adjacent the upper surfaces of the base members. Tubes inserted through the holes unite the base members to form the pallet. The base members consisting of three pressed carton pieces folded to a rectangular U-section, the length of each piece corresponding to the length of the base member. The first and the second pieces have a height substantially the height of the pallet. The third piece has an inner height dimension which is approximately the diameter of the tubes. The first carton piece in a base member has the U-section upright with the back of the U downwards, the second carton piece has the U-section as an inverted U-form disposed in the first carton piece. The third carton piece is located with its U-section upright and within and uppermost in the second carton piece. The distances between the vertical walls of the carton piece U-sections are dimensioned to fit closely to and in contact with each other, being tightly fixed by gluing. The holes for the tubes are located so the tubes lead through the space enclosed by the third carton piece uppermost in the base member. The said second carton piece can alternatively be the outer-most piece relative to the first and the third carton pieces.
