Flexible bag containing unit dose articles

Abstract

A flexible sealed bag containing a plurality of at least partially water soluble unit dose articles comprises a front panel, a back panel and a bottom panel. The front panel and the back panel may be marginally joined together along at least two opposed edges to be in a confronting relationship to form the closed bag. The front and back panels are joined at the top of the bag by a frangible seal. The bottom panel is intermediate to the front panel and back panel, and is joined to each of them.

What is claimed is: 
     
         1 . A flexible sealed bag containing at least one at least partially water soluble unit dose article having a major dimension, said bag comprising:
 a front panel and a back panel marginally joined thereto along at least two opposed edges to be in a confronting relationship to form a closed bag, said front panel and said back panel being joined at the top by a frangible seal;   a bottom panel intermediate to said front panel and said back panel, and joined to each of said front panel and back panel;   wherein said bag has a depth that is at least about two times that of the major dimension of said at least one unit dose article.   
     
     
         2 . The flexible sealed bag according to  claim 2 , wherein said bag has a depth of at least about 100 mm. 
     
     
         3 . The flexible sealed bag according to  claim 3 , wherein said at least one unit dose article has a major dimension of no greater than about 50 mm. 
     
     
         4 . The flexible sealed bag according to  claim 3 , wherein said unit dose article has a pincushion shape. 
     
     
         5 . The flexible sealed bag according to  claim 1 , wherein said bag has a height of less than about 300 mm. 
     
     
         6 . The flexible sealed bag according to  claim 1 , wherein said bag has an aspect ratio of from about 1:1 to about 1.3:1. 
     
     
         7 . The flexible sealed bag according to  claim 6 , wherein said bag has a tip angle of at least about 20°. 
     
     
         8 . The flexible sealed bag according to  claim 1 , wherein said articles comprise unit doses of a liquid laundry composition. 
     
     
         9 . The flexible sealed bag according to  claim 1 , wherein said bag comprises a polymeric film throughout, and said front panel of said bag is generally rectangularly shaped and comprises spaced apart side edges defining a width there between, said side edges of said front panel being heat sealed to corresponding side edges of said back panel. 
     
     
         10 . The flexible sealed bag according to  claim 1 , further comprising at least one window. 
     
     
         11 . The flexible sealed bag according to  claim 1 , comprising a bottom seal selected from the group of: parabolic seal, delta seal or square seal. 
     
     
         12 . The flexible sealed bag according to  claim 11 , comprising a square seal. 
     
     
         13 . The flexible sealed bag according to  claim 12 , said bag having a depth of about 100 mm. 
     
     
         14 . A series of flexible sealed bags according to  claim 1 , wherein each of said bags has a height less than about 300 mm and each of said bags differs in height by about 20 to about 30 mm. 
     
     
         15 . The series of flexible sealed bags according to  claim 13 , wherein each of said bags contains a different quantity of unit dose articles. 
     
     
         16 . A flexible sealed bag containing a plurality of at least partially water soluble unit dose articles containing liquid laundry composition and having the same major dimension, said bag comprising:
 a front panel and a back panel marginally joined thereto along at least two opposed edges to be in a confronting relationship to form a closed bag, said front panel and said back panel being joined at the top by a frangible seal;   a bottom panel intermediate to said front panel and said back panel, and joined to each of said front panel and back panel;   wherein:   said bag has a depth of about 100 mm;   said major dimension is about 50 mm; and   said bag has an aspect ratio of about 1:1.3.
