Abstract: A container used for containing powders such as a washing powder and the like has bottom stopper means for fixedly supporting another container when another container is inserted into the container. When a lot of containers are stored before containing contents therein, many can be stacked on top of one another. With these containers, the space needed for storing can be reduced.

Abstract: A container used for selling powders such as a washing powder and the like comprises a main body for filling the powders therein and a lid member for covering an upper opening of the main body. A band member is disposed through a score at a peripheral edge of the lid member except at a part of the peripheral edge thereof and has a peeling-off projection formed at its end. A picking-up projection is disposed at a wall of the lid member just above a space where no band member is defined. Each of these projections has a rectangular shape and has opposite surfaces. The surfaces of the peeling-off and picking-up projection are at approximately right angles to each other. These projections serve to protect one another from impacts or shocks exerted on one another. As the result, these projections are prevented them from deformation. Therefore, the container gives confidence that it can be opened by the impacts or the shocks exerted thereon at ease.

Abstract: A divisible package box comprising a main sheet and a partition body, the main sheet including a bottom, two side and two cover sections, flaps and a cutting line such as a cutting tape or a perforated line across the bottom section and the bottom flaps, the partition body consisting of two partition members in back to back contact with each other, each partition member including a partition section and two end sections at its ends, the sections and the flaps being defined by score lines for folding therearound. The end sections and the side flaps constitute end faces of an assembled package box so that the inner surfaces of all faces thereof may be completely flat. The assembled package box may be divided into two small boxes along the cutting line and the partition sections which constitute each end face of the divided two small boxes.

Abstract: A clamp lift truck for lifting a rectangular hexahedral stack of boxes incorporating a vertically movable four-side clamp lift employing a plurality of uniformly dimensioned generally flat clamp plates having widths substantially covering the surroundings of the rectangular hexahedral stack of boxes. The flat clamp plates are supported to be adapted for closely abutting against two pairs of opposing sides of the stack of boxes so as to clamp the stack with entirely uniform clamping force. A drive mechanism is utilized for driving the clamp lift into an open position for receiving the stack therebetween and a closed clmap position for simultaneously clamping two pairs of sides of the stack.

Abstract: A process for making collective packing unit boxes, comprising the steps of feeding a plurality of unit boxes by a first conveyor, thrusting the unit boxes one by one from the first conveyor to a second conveyor perpendicular thereto, thereby to cause the front side of each unit box to contact with the backside of the immediately preceding unit box, respectively, collecting a predetermined number of unit boxes together when the unit boxes are thrust from the first conveyor to the second conveyor, bringing down two flaps extending from the opposite edges of the collected unit boxes inwards, daubing an adhesive on the top flaps of the unit boxes, daubing an adhesive on the upper portions of the two sides of each unit box perpendicular to the contacting sides thereof, pressing a common lid onto the top of the collected predetermined number of unit boxes so that the lid may be adhered on the top flaps of the collected unit boxes, and folding the two opposite side edges of the lid so that the side edges are adhere

Abstract: An apparatus for measuring a restoring force necessary for raising folded portions of a hard paper box is disclosed. The apparatus comprises a base plate to which is attracted one folded portion of the hard paper box by means of vacuum, a hollow rotary wing to which is attracted another folded portion of the hard paper box by means of vacuum, means for rotating the hollow rotary wing together with said another folded portion around a ruled folded line edge formed between said one folded portion and said another folded portion, said one folded portion attracted to said base plate being kept stationary, and means for measuring difference between a force necessary for rotating said hollow rotary wing under no load condition and a force necessary for rotating said hollow rotary wing under a load condition.
