Twin chamber humidifying tube

The present application claims priority to Spanish Application No. P200703151 filed Nov. 27, 2007, which is incorporated herein in its entirety by reference.

1. Field of the Invention

The invention applies to the manufacturing of various articles and accessories in the Tobacco Industry and Smokers alike. Particularly, the present invention relates to a twin-chamber humidifying tube, permitting an even spread of moisture on each side of the cigar up to six months without drying out, thanks to the twin chamber system in the tube. The present invention also allows the recovery of dried cigars. Apart from the humidifying role of the art, the invention provides an advertising opportunity since cigars stored in it can be viewed from the outside.

2. Description of the Prior Art

Cigars also known as “puros” or by its place of origin “habanos” are cigars made from rolled tobacco leaves without the use of wrapping paper.

The main place of origin of cigars is Cuba, a country in which apart from its lands, special weather conditions such as temperature and humidity take place.

Cigar Smoking requires certain tobacco conditions to be able to sense its organic features specially the aroma as well as to be able to consume it trouble free and effortless.

However exporting and consuming cigars in different parts of the world other that the place of origin where environmental conditions such as temperature and humidity differ from the latter, requires appropriate protection during the process of transport and storage at the tobacconists prior to be purchased by the final consumer as well as the consumer itself.

Tobacco Shops would normally be fitted with big humidors (whether a room or furniture) providing special conditions of temperature and humidity.

On the consumer side the industrial approach of building a room or buying furniture to keep Cigars becomes unsuitable, therefore preserving Cigars would require the use of smaller humidors such as a wooden box type furniture with a humidifying system, consisting of a wet sponge that would keep suitable conditions of Cigars prior to consumption. This system requires periodical water replacement and for that the system includes a hygrometer indicating the humidity level inside.

Additionally, certain types of portable humidors are in use by consumers when carrying Cigars from their homes to a different place of consumption. These small sized leather cases, generally allowing 1 to 3 cigars, do not contain a humidifying system as such, although a few improvements has been done the matter. The effectiveness of these portable items lie on the leather isolation preventing or delaying the cigar to get dry therefore these shall not be considered as humidors as such. Examples of these improved items can be found in U.S. Pat. No. 6,112,889 or Utility Model 1 042 493[U 9900653](ES).

Another example of items preserving cigars is the aluminium cigar tubes or cigar carriers mostly for individual use and containing on one of the ends a wet sponge acting as the humidifying system moisturizing the tube inside. Although certain level of humidity is obtained, this item does not provide optimal conditions of cigar preservation. The tube can be found in U.S. Pat. No. 5,957,277 or Utility Model 1 000 746[U 8601104](ES).

The existence of the wet sponge on one of the ends inside the tube as source of humidity causes the destruction of the cigar due to an uneven moisturizing process, pushing water vapour directly and concentrated on one end of the cigar, the excess of humidity on the affected zone will lead to the swelling of it and the irreversible destruction plus a humidity defect on the rest of the cigar.

The optimum conditions for Cigar preservation are temperatures between 18-22 degrees Celsius in a 65-75% humidity level environment, with an even and gentle yet slow moisturizing process all around the cigar to avoid destruction due to excess of humidity.

So to avoid further problems with the humidification process in such aluminium portable tubes known till now, the present invention related to a twin-chamber humidifying tube which features an uniform and slow moisturizing event with the cigar thanks to the twin chamber system, that also permits the revival of dried cigars. To keep an appropriate level of humidity it is only required to gradually replace water prior to the provided sponge dries out completely.

Additionally a transparent section of the tube permits an external view of the cigar, the ring and cigar brand, representing in overall a new development unknown till today and providing many advantages on its marketing and advertising functions.

The present invention seeks to provide a twin chamber humidifying tube for maintaining adequate humidity in cigars comprising: (a) an outer cylindrical section including an air tight container outer tube divided in a first sub-section and a second sub-section; (b) a humidifying system, adjacent to a lower edge of the second sub-section; (c) a cap-type cigar punch, adjacent to an upper edge of the first sub-section; (d) an inner cylindrical section including an inner tube coaxially placed inside the second sub-section and of a diameter slightly smaller than the diameter of the outer tube and of a length a half of the length of the outer tube, constructed and arranged to define an inner chamber to contain a cigar, and (e) an outer chamber defined between the outer tube and the inner tube, constructed and arranged to enable a flow of humidity penetrate the inner chamber.
