Multi-chamber tube package

Abstract

A multi-chamber tube package which comprises a first tube chamber having a tube nozzle channel extending from a tube shoulder and terminating in an outlet, and a second tube chamber having a tube nozzle channel terminating in an outlet adjoining the first outlet. The tube nozzle channels enable the dispensing of the multiple preparations from the chambers. The nozzle channels lead to an outlet where the first preparation and the second preparation meet and coalesce to form a common strand. The two channels and the chambers associated with them have a defined ratio to each other. One nozzle channel may be subdivided into one or more parallel branches and/or the nozzle channels may have orifice rims or edges which lie on different planes.

1 . A multi-chamber tube package having a tube neck with an outlet and at least two chambers, comprising 
 exterior tubing with a tube shoulder and a nozzle channel terminating in an orifice in said outlet, said exterior tubing providing a first of said at least two chambers adapted to be charged with a first preparation, and    interior tubing with a tube shoulder and a nozzle channel terminating in an orifice in said outlet, and providing a second of said at least two chambers adapted to be charged with a second preparation,    said orifices being adapted to dispense said first and second preparations from said outlet so as to coalesce and from a common strand,    said two chambers having different volumes which are in a certain ratio to one another, and said nozzle channels having cross sectional areas which are substantially in the same certain ratio.    
   
   
       2 . A multi-chamber tube package according to  claim 1  wherein at least one of said nozzle channels is divided into at least two parallel branch channels.  
   
   
       3 . A multi-chamber tube package according to  claim 1  wherein one of said first and second chambers is filled with a preparation selected from the group of a precursor of a direct dye and nature-analogous dye, and the other chamber is filled with a preparation comprising at least one conditioning substance.  
   
   
       4 . A multi-chamber tube package according to  claim 1 , wherein said certain ratio is in the range from (greater than 1):1 to 5:1.  
   
   
       5 . A multi-chamber tube package according to  claim 1 , wherein one of said chambers is filled with a preparation comprising at least one oxidation dye precursor, and the second chamber is filled a preparation comprising at least one oxidant.  
   
   
       6 . A multi-chamber tube package according to  claim 1 , wherein one of said chambers is filled with a preparation comprising at least one oxidation dye precursor, and the second chamber is filled a preparation comprising at least one conditioning substance.  
   
   
       7 . A multi-chamber tube package according to  claim 1 , wherein said orifices in said outlet have edges which are at different levels in said outlet.  
   
   
       8 . A multi-chamber tube package according to  claim 7 , wherein the levels of said orifices are different by at least 0.3 millimeter.  
   
   
       9 . A multi-chamber tube package according to  claim 8 , wherein said level difference is more than 1.0 millimeter.  
   
   
       10 . A multi-chamber tube package according to  claim 7 , wherein the orifice of said interior tubing is at a level higher than the level of the orifice of the exterior tubing.  
   
   
       11 . A multi-chamber tube package according to  claim 10 , including a closure for said outlet adapted to be placed over said outlet, said closure including side walls adapted to encircle the outlet and an internal lining adapted to seal the orifices, said lining comprising a resilient compressible material having a part, upon displacement of said closure, adapted to be penetrated by the orifice at a higher level to seal said higher orifice, the remaining part being adapted to seal the other of said orifices.  
   
   
       12 . A multi-chamber tube package according to  claim 11 , wherein said closure is a screw-on cap adapted to be telescopically engaged with the outlet.  
   
   
       13 . A multi-chamber tube package according to  claim 11 , wherein said outlet has an abutment, and said closure has a stop adapted to engage said abutment and limit further displacement of said closure after said remaining part has sealed said other orifice.  
   
   
       14 . A multi-chamber tube package according to  claim 1 , wherein said the exterior tubing coaxially surrounds said inner nozzle channel, said inner nozzle channel being pipe-like with an outer wall of said inner nozzle channel separating the two nozzle channels.  
   
   
       15 . A multi-chamber tube package according to  claim 1 , wherein said inner nozzle channel has lobes in the shape of a star, where the cross-sectional area of the star defines the substream for the preparation located in the chamber associated with said nozzle channel, inner tube, and lobes of the star engage the inner wall of the outer channel to produce interstitial spaces between the outer wall of the inner nozzle channel and the inner wall of the outer nozzle channel to define parallel branch channels for the preparation to be dispensed through the outer nozzle channel.  
   
   
       16 . A multi-chamber tube package according to  claim 1 , wherein the chambers associated with the outer and inner nozzle channels comprise flexible outer and inner tubes which have been sealed at the rear end by means of a shared folded joint.  
   
   
       17 . A multi-chamber tube package according to  claim 16  wherein at least one of said outer and inner tubes comprises a material selected from the group consisting of a plastics-coated aluminum foil, an aluminum laminate, and a plastics laminate.  
   
   
       18 . A multi-chamber tube package according to  claim 16 , wherein at least one of said outer and inner tubes comprises transparent plastic.  
   
   
       19 . A multi-chamber tube package having a tube neck with an outlet and at least two chambers, comprising 
 exterior tubing with a tube shoulder and a nozzle channel terminating in an orifice in said outlet, said exterior tubing providing a first of said at least two chambers adapted to be charged with a first preparation, and    interior tubing with a tube shoulder and a nozzle channel terminating in an orifice in said outlet, said providing a second of said at least two chambers adapted to be charged with a second preparation,    wherein said orifices in said outlet have edges which are at different levels in said outlet,    said orifices being adapted to dispense said first and second preparations from said outlet so as to coalesce and from a common strand,    
   
   
       20 . A multi-chamber tube package according to  claim 19 , wherein said the exterior tubing coaxially surrounds said inner nozzle channel, said inner nozzle channel being pipe-like with an outer wall of said inner nozzle channel separating the two nozzle channels.
