Retractable and flexible plastic container for liquids

Abstract

This invention relates to the structure of a corrugated tube which can be compressed and extended but also it can adapt to all the inclinations required by the user, being really retractable and flexible. This fact can be adopted for the production of a special urinal but also of a retractable bottle.

1 - A retractable and flexible plastic container for liquids with a neck portion for the insertion of a conveyer or a screwing cap, said container being a corrugated tube formed by a plurality of convolutions, which allow the retractility and the flexibility of the same tube, characterized in that the upper ring of every convolution is bigger than the lower one and the curvatures of the external point of the convolutions, point of greatest extension, have an external bulge which in the lower point of connection of the two rings forms a hinge, the curvatures of the internal point, point of settlement, are sharp like an engraving. 
   
   
       2 - A retractable and flexible plastic container for liquids where, with reference to  claim 1 -, the corrugated tube is produced with the process of blowing. 
   
   
       3 - A retractable and flexible plastic container for liquids where, with reference to  claim 1 -, the corrugated tube is produced with the process of injection-blowing. 
   
   
       4 - A retractable and flexible plastic container for liquids where, with reference to  claim 1 -, a conveyer for the male-female urinating organ is inserted from its neck, this conveyer has a structure joined through a hinge to the closing cap, its closing is tight because the edge of the cap enters the edge of the structure hermetically, the cap has a protuberance in its centre, the cap has a grip on the opposite side of the hinge. 
   
   
       5 - A retractable and flexible plastic container for liquids where, with reference to  claim 4 -, a quantity of an absorber polymer is put inside a semispherical or cylindrical small cap which, once filled of this compound, is inserted into the interior of the protuberance of the cap of the conveyer. 
   
   
       6 - A retractable and flexible plastic container for liquids which, with reference to  claim 1 -, has the neck and the bottom as a normal bottle which can be compressed or extended, due to its retractility, to improve its storage, to improve the preservation of the contained liquid, and can be flexed, due to its flexibility, to improve its use. 
   
   
       7 - A retractable and flexible plastic container for liquids where, with reference to  claim 6 -, a screwing cap is inserted from its neck, this cap is the same normally used for the closing of plastic bottles, having this neck the same threads of a normal plastic bottle. 
   
   
       8 - A retractable and flexible plastic container for liquids where, with reference to  claim 7 -, a conveyer is screwed to the bottle's neck because the bottom of the same conveyer has the same diameter and the same threads of the original cap of the bottle.
