Embodiment Construction

[0019] Although the present invention can be embodied in many different forms, a preferred embodiment of the present invention will be described in detail herein with reference to the accompanying drawings. The present disclosure is to be considered as exemplifying the principles of the invention and is not intended to limit the invention in its broader aspects to the embodiments shown and described.

[0020] figure 1 and figure 2 A flexible container device 10 is shown having a first side wall 12 and a second side wall 13 affixed to a perimeter 14 to form a fluid tight chamber 16 . A spout 18 is attached to the outer surface of the side wall 12 and provides access to the chamber 16 for liquid inflow. In one preferred form of the invention, the first side wall 12 and the second side wall 13 are a soft polymeric material having a modulus of elasticity of less than 50,000 psi. The sidewalls are preferably made of, for example, copolymers of homopolymers and polyolefins, poly...

Abstract

A flexible polymeric container for storing and dispensing liquids includes a first sidewall and a second sidewall connected together to define a fluid chamber therebetween. The first sidewall and the second sidewall each have an inner surface facing the fluid chamber and an opposed outer surface. A fitment is attached to an outer surface of one of the first sidewall or the second sidewall. The fitment has an opening therethrough which has an axis substantially perpendicular to the outer surface. A plurality of objects on the inner surface of one of the first sidewall or the second sidewall defines a plurality of pathways having at least a first pathway and a second pathway intersecting one another.

Description

[0001] This application is a continuation-in-part of U.S. Nonprovisional Patent Application Serial No. 10 / 037,295 filed December 21, 2001, which claims the benefits of Serial No. 60 / 332,463, both of which are hereby incorporated by reference and made a part of this document. technical field [0002] The present invention relates generally to a flexible plastic container, and more particularly to a flexible container that directs flowable material contained therein to an appendage of the container and dispenses the flowable material. Background technique [0003] Collapsible plastic bags are commonly used to store liquid products such as chemicals, soft drink syrups, juices and food condiments. Plastic bags are often contained in corrugated cardboard boxes to facilitate shipping, handling and distribution of the product. Such packaging systems are often referred to as "bag-in-box" packaging systems. [0004] Plastic bags typically have side walls sealed along peripheral se...
