Nestable container
Nestable container , (Engl. Nested container ) also logistics boxes , distribution containers , containers with stacking brackets , conical returnable containers or letter boxes are transport or storage containers made of plastic. It is possible to plug the containers into one another (“nest”) when empty, in order to save volume when storing or returning the empty boxes.
description
Nestable containers are rigid containers; the upper edge is turned inside out and forms a circumferential grip strip. They cannot be folded or collapsed. However, they cannot be stacked without additional accessories. In order to be able to stack them on top of one another, they need a lid or special stacking brackets that are attached to the inner edge of the container. If the lid is opened or the stacking brackets are folded over, the containers can slide into one another due to their conical shape. The edge of the upper container comes to rest on the edge of the lower one. With this construction, the volume reduction only becomes effective from the second container onwards, so it is less than with comparable collapsible or collapsible containers .
The side walls of the nestable containers are mostly closed. In this way a very rigid construction is achieved, through which they achieve both high load-bearing capacity and load-bearing capacity in the stack. In addition, they are hardly susceptible to torsion . However, the disadvantage of this one-piece construction is that the boxes cannot be repaired. Individual parts are not interchangeable; if they break, the entire box cannot be used anymore. Because of the conical shape of their side walls, nestable containers have an interior volume that is approx. 20% smaller than containers of the same size with vertical walls.
Smaller nestable containers are manufactured using the injection molding process. To do this, plastic granulate is melted and pressed into metal molds under high pressure. Nestable containers are produced in various basic dimensions up to 800 mm × 600 mm as well as special dimensions.
Larger nestable containers with a Euro pallet size of 1200 mm × 800 mm can also be produced using the pressing process. Usually they then consist of fiber-reinforced thermosetting plastics such as SMC . Minor damage can be repaired on a thermoset.
use
Nestable containers are the oldest form of volume-reducible containers. They have been partially replaced by more modern systems such as collapsible or collapsible containers , but are still popular in some industries because of their robustness. Nestable containers can be used on automatic conveyor systems such as roller conveyors or conveyor belts. In some industries, they are particularly suitable for individual container labeling using barcodes or RFID chips.
