What is DENESTING? (DE-NESTING)

Quite simply, DENESTING is the term used for the separation of items or products which are nested together. In order that items or products are able to be nested together, they must conform to a certain shape, of which a typical example would be a disposable paper or plastic cup. The cup has a thin wall and is tapered in form. The diameter of the top of the cup is suitably larger than the diameter of the base of the cup. This allows identical cups to fit partially inside each other. In the example of the cup, the benefits are that cups may be stored more efficiently before use and multiple cups can be transported easily in one hand (without drinks in, of course). Additionally, used cups may be disposed of more efficiently if they are re-stacked.

Further examples of common items which are able to be NESTED together are:

Well, you get the idea. Ok, more about DE-NESTING.

Common problems associated with Denesting

Design of containers or items which nest together can be complex, and is relative to how the containers/items are commonly handled. For example, plastic buckets commonly fit tightly inside each other, which enable them to be pressed together and held by friction. This ‘holding together’ is generally ok for plastic buckets sold in a local hardware store, because separation of the buckets can be done without too much trouble and may only take 3 to 5 seconds, which is unlikely to cause a problem to any potential user. The benefit of this frictional location of the buckets is that they are able to be kept neatly together for simple transportation and storage.

In general, the principle of items that may be NESTED together is a very common one, and in fact, examples of this can be found throughout every-day life. The ability for commercial products to use these design features is a very valuable one, as for most products which exploit these features are of very low monetary value and would not be financially viable, did they not have the ability to stack together. Design of commercial products such as disposable food trays can be critical. Although the products have a very low individual value, the ease at how the product may be handled often far exceeds this individual value.

Disposable food trays used in a food factory production line must have the ability to be stored away neatly, taking up minimum amount of factory floor space, but also must be ‘freely DE-NESTABLE’. The ability for the tray to be DENESTED quickly and freely on to factory conveying equipment, repeatedly and without error is a very important factor in the cost effective and efficient running of any factory.

To further improve the day to day task of DENESTING, it can be automated by the use of special DENESTING machinery. These easily installed, stand alone machines, combined with an efficient tray/product design, can handle extremely high volumes of product, far in excess of that which may be handled by human operators. In addition to increased potential throughput, DENESTERS can be installed in situations where it may be deemed as a dangerous environment for human operators to be working. Cases where operators are likely to suffer RSI (repetitive strain injury) will also be reduced by installation of DENESTING machinery.
