DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a thermal insulated bottle, particularly adapted for sports and leisure, as well as for home and professional activities. More particularly, the thermal insulated bottle according to the invention is of the type comprising an inner container enclosed within an outer housing and coupled thereto by sealing connecting means to define therebetween a substantially airtight hollow space, ornamental and/or indicating elements associated with the bottle and visible from the outside.
BACKGROUND ART
Thermal insulated bottles are known which have the inner container and the outer housing generally made of the same basic material such as for example aluminium or plastics and are not optically transparent so as to reduce heat transmission induced by the light. The ornamental and/or indicating elements normally consist of labels which are either attached to the outer surface of the housing or directly printed on this latter.
A drawback of the known aluminium bottles resides in that they are subject to permanent deformation and to scratches caused by impacts. Moreover, also the ornamental and indicating elements may suffer damages consequent to abrasions and hits thereby detracting the overall appearance and attractiveness of the bottle.
A drawback of the known plastics bottles reside in that the paints used for the ornamental elements, the inscriptions and the decorations may release smells at relatively high temperature. In addition, even though the sidewalls of the housing have an impact resistance higher than that of the aluminium bottles, in this case the decorating and the indicating elements can be easily removed from hits or abrasions and can be damaged by atmospheric agents. A problem of the known thermal insulated bottles is that in several cases it may be helpful or necessary to know the temperature of the liquid contained in the bottle, in order to avoid burning when drinking too hot liquids or to avoid dispensing of liquids too cool for several uses.
A simple method for measuring the temperature of the liquid would be that of introducing a thermometer into the inner container or attaching it to a closure of the bottle, however this would render the bottle rather cumbersome, expensive and breakable.
DISCLOSURE OF THE INVENTION
A primary object of the present invention is to obviate the above mentioned drawbacks by providing a thermal insulated bottle having ornamental and indication elements with high resistance to impacts, abrasions and atmospheric agents and which is capable to furnish to the outside information on the liquid contained in the bottle without opening it.
Another object is to provide a thermal insulated bottle which allows to know with a relatively high precision the temperature of the liquid contained in the bottle within a limited range of temperature.
These and other objects which will be clearly apparent hereinafter are accomplished by a thermal insulated bottle which comprises an inner container for receiving a liquid, a housing arranged outwardly of the container and coupled thereto by sealing connecting means to define therebetween a substantially airtight hollow space, ornamental and/or indicating elements associated with the bottle and visible from the outside, characterised in that said ornamental and/or indicating elements are located within said hollow space, said outer housing having at least a part optically transparent through which the ornamental and/or indicating elements are visible from the outside while being protected from atmospheric agents, impacts and/or abrasions. Advantageously, the outer housing can be made by a substantially uniform, clean and optically transparent material chosen among thermoplastics materials including polyethylene, polypropylene, PVC and polycarbonate or glass.
Preferably, the inner container is made of a material having a relatively high thermal conductivity chosen among aluminium, steel, glass, carbon and other natural or synthetic materials.
The ornamental elements may be constituted by a
