Fluids container
The present invention provides a method for treating a surface of a layered polymeric structure. The method includes the steps of: (1) providing a film having a layered structure formed by adhering first and second non-molten polymeric sheets in an overlap and texturing a surface of the first or second non-molten sheets with a chill roll to form fluid pathways on a surface of the film; (2) attaching an access member to the film; and (3) forming the film into a container having a peripheral seal defining a chamber, and having the fluid pathways facing the chamber and having the fitment providing access to the chamber.
1 . A method for forming a container comprising:
providing a film having a layered structure formed by adhering first and second non-molten polymeric sheets in an overlap and texturing a surface of the first or second non-molten sheets with a chill roll to form fluid pathways on a surface of the film;
attaching an access member to the film; and
forming the film into a container having a peripheral seal defining a chamber, and having the fluid pathways facing the chamber and having the fitment providing access to the chamber.
2 . The method of claim 1 wherein the first and second non-molten sheets are joined together by directing a molten polymeric material into the overlap.
3 . The method of claim 1 wherein the container has opposed sidewalls each sidewall having fluid pathways facing the chamber.
4 . A fluid container comprising:
a wall defining a chamber, the wall having a layered structure formed by adhering first and second non-molten polymeric sheets in an overlap and texturing a portion of the surface of the first or second non-molten sheets with a chill roll to form fluid pathways on a portion of the surface of the film facing the chamber; and
an access member fixedly attached to the wall for providing access to the chamber.
5 . The container of claim 4 wherein the wall has opposed portions defining opposed sidewalls, each sidewall having an inner surface facing the chamber and at least a portion of one of the opposed sidewalls having the fluid pathways.
6 . The container of claim 5 wherein portions of each opposing sidewall inner surfaces having fluid pathways.
7 . The container of claim 4 wherein the fluid pathways define a waffle pattern.
8 . The container of claim 4 wherein the fluid pathways define a brick-wall pattern.
9 . The container of claim 4 wherein the fluid pathways are defined by a plurality of spaced objects.
10 . The container of claim 9 wherein the objects have a generally circular shape.
11 . The container of claim 9 wherein the objects have a polygonal shape.
12 . The container of claim 9 wherein the objects have an irregular shape.
13 . The container of claim 9 wherein the objects have a generally teardrop shape.
14 . The container of claim 9 wherein the objects have a first set of objects with a first shape and a second set of objects with a second shape different from the first shape.
15 . The container of claim 9 wherein the objects are dimension to fit within gaps separating the objects to define a self-interlocking pattern.
16 . The container of claim 4 wherein the first non-molten sheet is a monolayer structure or a multiple layered structure.
17 . The container of claim 4 wherein the first non-molten sheet is a monolayer structure.
18 . The container of claim 4 wherein the first non-molten sheet is a multiple layered structure.
19 . The container of claim 18 wherein the multiple layered structure has a first layer and a second layer.
20 . The container of claim 19 wherein the first layer is a polyolefin.
21 . The container of claim 20 wherein the second layer is a barrier material.
22 . The container of claim 4 wherein the second non-molten sheet contains a layer of a polyamide or a layer of a polyester.
23 . A fluid container comprising:
a wall defining a fluid tight chamber and having an inner surface facing the chamber;
an access member attached to the wall and providing fluid access to the chamber;
a pattern on the inner surface defining a fluid pathway to the access member, the pattern having an object spaced from a gap and the object being dimensioned to fit into the gap to interlock the object and the gap.
