Abstract

This invention relates to a liquid containing pouch sealed in a carton with the pouch having a spout connected thereto. The spout projects through a hole in the carton and is secured to the carton. The pouch is sealed at the spout and is opened by means of a piercing device incorporated within the spout which is moved axially in the spout for opening the pouch. The piercing device is mechanically actuated through movement of a tubular portion of the spout telescopically fitted therein and carrying the piercing element. Further axial movement of the piercing device is obtained through rotatable movement between the spout and the tubular portion to fold flap portions of the pouch, pierced by the piercing element, such as to enable complete dispensing of liquids therefrom. The spout includes a valve which seals the pouch after opening by the piercing element such that liquid may be extracted from the pouch as the pouch is collapsed within the carton. The valve forms an airlock to restrict passage of air into the pouch during and after dispersing of liquids therefrom.

Dependent claims

A container for dispensing fluids comprising:

a carton having sides defining a generally rectangular cross section with a sealed bottom and top end;
said carton being made of paper material and having an aperture through the sealed top end, a flexible pouch of plastic material positioned in said carton, said pouch being formed with seamed edges defining sides and a top;
a spout sealed to the top of the pouch, said spout having a flange surface projecting therefrom;
a sleeve member positioned telescopically over the spout;
said sleeve member having a flange surface which cooperates with the flange surface of the spout when the spout is positioned through the aperture in the carton to combine and bear against the inside and outside surfaces of the carton;
a piercing element telescopically fitted within the spout to open the pouch, means movably mounting the piercing element within said spout to permit movement of the piercing member relative to the spout to open the pouch said means movably mounting said piercing element including a tubular member slidably positioned within said spout, means included in the mounting of the tubular member in the spout to advance the tubular member and the piercing element relative to the spout to pierce the pouch, and means included in said mounting of the piercing element for advancing the piercing element further into the pouch upon relative rotative motion between the tubular member and the piercing element.
