DESCRIZIONE DESCRIPTION
a corredo di una Domanda di Brevetto per Invenzione Industriale in support of a Patent Application for Industrial Invention
avente per titolo: having the title:
?POSATE MONOUSO COMPOSTABILI RESISTENTI ALLE SOLLECITAZIONI? ?SINGLE USE COMPOSTABLE CUTLERY RESISTANT TO STRESS?
La presente invenzione si riferisce ad una posata da tavola monouso compostabile, idonea per consumare cibi solidi o liquidi senza contatto diretto delle mani del consumatore con essi, comprendente un elemento in pezzo unico in polpa di cellulosa avente un unico bordo continuo, comprendente una porzione allungata di impugnatura ed una porzione utile idonea a sporzionare e/o raccogliere cibi e/o liquidi. The present invention relates to compostable disposable table cutlery, suitable for consuming solid or liquid foods without direct contact of the consumer's hands with them, comprising a single-piece cellulose pulp element having a single continuous edge, comprising an elongated portion handle and a useful portion suitable for dividing and/or collecting food and/or liquids.
Le posate compostabili in polpa di cellulosa dello stato della tecnica sono affette dall?inconveniente di avere una scarsa resistenza alle sollecitazioni esterne di compressione, flessione e torsione incontrate nel normale uso, ci? che rende le stesse frequentemente soggette a piegamento o rottura. State-of-the-art compostable cellulose pulp cutlery suffers from the drawback of having poor resistance to external compression, bending and torsion stresses encountered in normal use. which makes them frequently subject to bending or breaking.
Pertanto, ? scopo della presente invenzione fornire una posata monouso compostabile in polpa di cellulosa avente resistenza meccanica sostanzialmente maggiore rispetto a quelle dello stato della tecnica, tale che non sia soggetta a rompersi o piegarsi nell?uso normale. Therefore, ? The object of the present invention is to provide disposable compostable cutlery made of cellulose pulp having substantially greater mechanical strength than those of the state of the art, such that it is not subject to breaking or bending in normal use.
Tale scopo ? raggiunto dalla presente invenzione con una posata da tavola monouso compostabile interessata da costole di rinforzo lungo il bordo e/o nella porzione di impugnatura di essa, fino a sporgere nella porzione utile, come per esempio forchetta, coltello o cucchiaio, di essa. That purpose? achieved by the present invention with a disposable compostable table cutlery affected by reinforcing ribs along the edge and/or in the handle portion thereof, up to protruding into the useful portion, such as for example fork, knife or spoon, thereof.
Inoltre, le posate compostabili in polpa di cellulosa dello stato della tecnica sono realizzati con cellulosa pura estratta per esempio da conifere come per esempio pino, abete, larice, o da latifoglie come per esempio pioppo, faggio, betulla, eucalipto. Questo tipo di materia prima, nonostante riduca l?impatto ambientale in termini di riduzione di rifiuti plastici, presenta l?inconveniente di utilizzare come materie prima la cellulosa estratta dagli alberi, favorendo il disboscamento e provocando un impatto ambientale negativo. Furthermore, state-of-the-art compostable cellulose pulp cutlery is made with pure cellulose extracted for example from conifers such as pine, fir, larch, or broad-leaved trees such as poplar, beech, birch, eucalyptus. This type of raw material, despite reducing the environmental impact in terms of reducing plastic waste, has the drawback of using cellulose extracted from trees as raw material, favoring deforestation and causing a negative environmental impact.
Pertanto, secondo una forma di realizzazione detta polpa di cellulosa ? polpa di cellulosa di recupero. Therefore, according to one embodiment said cellulose pulp ? recycled cellulose pulp.
Pertanto, costituisce oggetto della presente invenzione una posata da tavola monouso compostabile secondo l?allegata Rivendicazione 1. Therefore, the subject of the present invention is a compostable disposable table cutlery according to the attached Claim 1.
