Flexible Container with Fitment

Abstract

The present disclosure provides a flexible container. In an embodiment, the flexible container includes (A) four panels, each panel comprising a flexible multilayer film. The flexible multilayer film includes a polymeric material composed of a polymeric material. The four panels form (i) a body, and (ii) a neck. The flexible container includes (B) a fitment having a top portion and a base. The fitment is composed of a polymeric material. The base is sealed in the neck. The base has (C) a cross-sectional shape with a diameter (d), and the base has a wall thickness (WT). The base has a d/WT ratio wherein the d/WT ratio (in mm) is from 35 to 800.

1 . A flexible container comprising:
 (A) four panels, each panel comprising a flexible multilayer film comprising a polymeric material, the four panels forming
 (i) a body, and 
 (ii) a neck; 
 (B) a fitment comprising a top portion and a base, the fitment composed of a polymeric material, the base sealed in the neck; and 
 (C) the base has a cross-sectional shape with a uniform diameter (d), the base has a wall thickness (WT), wherein the d/WT ratio (in mm) is from 35 to 800. 
   
     
     
         2 . The flexible container of  claim 1  wherein the cross-sectional shape of the base is selected from the group consisting of circle and regular polygon. 
     
     
         3 . The flexible container of  claim 1  wherein the cross-sectional shape of the base is a circle. 
     
     
         4 . The flexible container of  claim 1  wherein the cross-sectional shape of the base is a square. 
     
     
         5 . The flexible container of  claim 1  wherein the diameter of the base is greater than the diameter of the top portion. 
     
     
         6 . The flexible container of  claim 1  wherein the diameter (d) is from 10 mm to 120 mm. 
     
     
         7 . The flexible container of  claim 1  wherein the wall thickness (WT) is from 0.15 mm to 0.75 mm. 
     
     
         8 .
