Abstract
A pouch for containing wine or other oxygen-sensitive liquid is formed from superposed layers of plastic film having welds to define a rectangular pouch with a straight-sided or shallowly tapering passage communicating a main container portion of the pouch with the exterior of the pouch. When the pouch is full, this passage is sealed off by a further weld which is removed by the consumer to allow the consumer to insert a separate valve into the pouch for dispensing of the liquid.
