Pocket vial packaging and dispensing device

Abstract

A pocket vial device for packaging and dispensing fluid products has a flexible pouch placed in a rigid vial ( 9 ) and associated with a pump or a valve for expelling the product contained in the pouch, the pouch including a cylindrical wall made of at least one sheet ( 1 ) wound into a cylinder having one of its side edges tightly attached to a solid flange ( 8 ) defining the bottom of the flange, while the other is tightly attached to an annular flange ( 7 ) defining a fixation ring to the vial. The two longitudinal edges ( 3, 5 ) of the sheet ( 1 ) are tightly attached to each other and the end of the inner edge being masked by a flexible cover strip ( 6 ). The pocket vial device can be used for reducing the risk of contamination of the product contained in the pouch.

1 . A device for packaging and dispensing fluid product of the pocket-vial type comprising:
 a flexible pocket placed in a rigid vial, associated with a pump or a valve for expelling the product contained in the pocket, the pocket having a cylindrical wall with at least one sheet wound in a cylinder of which one of the lateral sides is attached in a sealed manner to a solid end-piece forming the bottom of the pocket, and the other is attached in a sealed manner to an annular end-piece forming a ring for attachment to the vial, wherein the two longitudinal sides of the sheet are attached to one another in a sealed manner and the edge of the inner side is masked by a flexible covering strip.   
     
     
         2 . The device as claimed in  claim 1 , wherein the covering strip is attached to each of the two longitudinal sides of the sheet, on either side of their junction on the inner wall. 
     
     
         3 . The device as claimed in  claim 1 , wherein the covering strip envelops the edge of the inner side of the sheet and is folded between the two sides. 
     
     
         4 . The device as claimed in  claim 1 , wherein the sheet forming the wall is single-layer or multi-layer. 
     
     
         5 . The device for packaging and dispensing fluid product as claimed in  claim 4 , wherein the multi-layer sheet comprises an aluminum sheet inserted between at least two plastic films chosen from a polyethylene, a polypropylene or a polymide. 
     
     
         6 . The device for packaging and dispensing fluid product as claimed in  claim 4 , wherein the multi-layer sheet is a polyethylene/paper/polyethylene complex. 
     
     
         7 . The device for packaging and dispensing fluid product as claimed in  claim 1 , wherein the covering strip is made of a material identical to the inner layer of the sheet. 
     
     
         8 . The device for packaging and dispensing fluid product as claimed in  claim 7 , wherein the sheet comprises at least one layer of polyethylene as an inner layer and the covering strip is made of the same polyethylene.
