DESCRIPTION:
BRIEF SUMMARY
This patent application concerns a cup for hot or cold drinks, made of an edible twice-baked pastry.
The article manufactured according to the invention represents a revolutionary innovation in the serving of drinks in the public catering sector.
As is well known, coffee and other hot drinks--such as tea, chocolate and the likes--are currently served to the public in ceramic cups.
Yet the use of such crockery is inevitably associated with various inconveniences of no small consequence.
In this respect, and above all, the expenses shouldered by the owner of a concern in order to acquire a sufficient number of such ceramic cups should be taken into account.
Secondly, it is important to consider the necessity to wash each cup immediately after use, such operation requiring considerable time and effort on the part of personnel, not to mention the cost inherent to the purchase and operation of a dishwasher, a now common and widespread appliance.
It must furthermore be noted that the cups used in public catering are increasingly suspected of being vehicles for the oral transmission of infectious diseases; it must be said that tests actually show that most viruses responsible for serious, and sometimes mortal, diseases are resistant even to the temperatures such cups are subjected to in normal washing cycles inside a common dishwasher.
To be honest, most of the above problems may be considered as being solved by the use of common disposable paper cups; yet the use of the latter type of containers is undoubtedly offset by the fact that it results in an enormous output of solid waste, which is moreover highly polluting as the paper used for such cups is plasticised.
The article manufactured according to the invention was conceived in consideration of the above mentioned problems.
It consists of a disposable container for hot drinks made of a pastry which is twice baked and--as such--bears the unique and innovative feature of being edible once the liquid contained in it has been drunk.
Such container may be shaped as a cup with its relative handle, but there is no reason why it may not be manufactured without a handle, as a simple beaker.
Vessels made with edible pastry are in fact already known.
Patent DE-A-4218392 describes a procedure for realising a cup for eating and drinking, which once used, can be eaten.
This patent clearly states that in order to make the edible pastry stable and impermeable, a certain quantity of macrcmolecular former such as xantorrea, is added which makes the pastry impermeable even to hot drinks.
In this procedure, the pastry to which a macromolecular former has been added, is pressed in the mould and baked at the same time.
U.S. Pat. No. 4,927,655 describes a procedure for moulding an edible vessel made of a pastry used in ice cream wafers, according to which the pastry is made by mixing sugar with wheat flour and adding oil, fat, eggs and water.
The pastry made in this way is placed and baked in a special mould in order to obtain an edible vessel of the shape and dimensions required.
This patent provides no teaching as to how to make the edible vessel impermeable and capable of keeping its shape and compactness when in contact with hot liquid such as coffee or tea, for a certain length of time.
Patent FR-A-2437996 describes an edible vessel for packaging which consists substantially of a vessel shaped biscuit made of a common edible pastry to which special substances are added to ensure a long shelf life.
This biscuit s coated with a chocolate and sugar icing layer which stops the biscuit from absorbing cold and moisture.
Therefore this coating does not make the biscuit impermeable, on the other hand it is clearly stated in this patent that said vessel shaped biscuit must not be used to hold drinks but only for making cakes, ice cream cakes etc.
The purpose of this invention is to realise a mono-use edible vessel which can hold hot drinks, even for a considerable length of time, without loosing its stability.
The vessel in question is made of a pastry like that used for making ice cre
