That the inventors are in first line to improve the life of all of us, this is well-known and it is showed, if ever there is need, by this innovative and present patent with the wicked present title. It is in fact one of the innumerable attempts published on this site in order to seek to give again a little bit of serenity and safety to all the world population, literally terrorised from the last dramatic events that unfortunately overwhelm the news on TV and the journalistic heads of all of the planet! The found in matter propose to itself in fact to conquer if not definitively at least in wide part, the serious problem of the envelopes with the anthrax that are delivered to Post Offices of part of the world, creating apprehension and dismay between the people. The working of this special patent is very simple and clever, using in fact some acetate paper or simply plastic for their packing, we obtain packages and envelopes absolutely transparent to test the eventual introductions of the notorious anthrax powder! From now on, if to commit this very hateful crime, will be used these special envelopes, the result will be that to make most of the fatal content visible outside and therefore easy to neutralise! Also in case that the quantity of the dangerous powder is smaller, there will be always a partial dimming of the special envelope, making so vain any criminal resolution. Another force point of the patent is the special closing system different from the normal envelopes at present in traffic, that in practice seals hermetically any content, not allowing the exit of any potential additional material, also in case of fine powder! The special envelope, maintains its perfect sealing efficiency even if the border is not correctly stuck, in virtue of the special patented building system. It will suffice at this point to pack all the envelopes and even the packages, adopting this sophisticated procedure and the relevant mentioned material, to put in serious difficulty eventual ill-intentioned, compelling them at least to review the actual criminal plans! Such solution will not have any repercussion on the technical plan, and the prices of the shipping will not undergo substantial variations, allowing ourselves so to look at final to the future with greater calm.
