Claim 1

Independent Claim 121 words

A collapsible container for fluids having an interior space defined by a pair of major surfaces capable of lying flatly upon one another at least one of said pair of major surfaces being provided 55 by a flexible sheet member, said interior space being divided into compartments by a pinching action between opposed first and second members, one of which may provide one of said pair of major surfaces, said first member providing 60 a plurality of ridges arranged to define boundaries of the said compartments, said second member providing a planar surface or surfaces against which the said ridges sealingly compress said flexible sheet member or members, some or all of said ridges having gaps therein defining passageways between compartments.

Claim 2

Dependent Claim 121 words

A collapsible container for fluids having an interior space defined by a pair of major surfaces capable of lying flatly upon one another at least one of said pair of major surfaces being provided 55 by a flexible sheet member, said interior space being divided into compartments by a pinching action between opposed first and second members, one of which may provide one of said pair of major surfaces, said first member providing 60 a plurality of ridges arranged to define boundaries of the said compartments, said second member providing a planar surface or surfaces against which the said ridges sealingly compress said flexible sheet member or members, some or all of said ridges having gaps therein defining passageways between compartments.

Claim 3

Dependent Claim 33 words

A container as claimed in Claim 1 wherein some or all of the said gaps in the said ridges are provided with valves for selectively opening and closing the respective passageways between compartments.

Claim 4

Dependent Claim 36 words

Claim 5

Dependent Claim 24 words

A container as claimed in Claim 1 or Claim 2 wherein the said interior space is defined by a pair of flexible sheet members.

Claim 6

Dependent Claim 32 words

A container as claimed in Claim 4 wherein the said second member is a plate member providing a continuous flat surface at least as large as the said pair of major surfaces.

Claim 7

Dependent Claim 25 words

A container as claimed in Claim 4 or Claim 5 wherein the ridges of the first member define all the walls of the said compartments.

Claim 8

Dependent Claim 29 words

A container as claimed in any one of Claims 4 to 6 wherein the said pair of flexible sheet members are sealed to one another to form a bag.

Claim 9

Dependent Claim 13 words

A container as claimed in Claim 7 wherein said sealing is by welding.

Claim 10

Dependent Claim 49 words

A container as claimed in Claim 8 wherein some of the walls of the said compartments are defined by the welds between the flexible sheet members and some by the said ridges and wherein where a ridge and a weld coincide, the weld is beadless proximate to the ridge.

Claim 11

Dependent Claim 25 words

A container as claimed in any preceding claim wherein the said first member is q. plate having said ridges depending from a major surface thereof.

Claim 12

Dependent Claim 55 words

A container as claimed in any preceding claim wherein the width of the tips of the said ridges is about two thirds the thickness of the flexible sheet member contacted by the ridge and wherein the ridges have substantially that width for a depth about one half of the thickness of the said sheet member.

Claim 13

Dependent Claim 25 words

A container as claimed in any one of the preceding claims wherein the or each of the said flexible sheet members is of plastics material.

Claim 14

Dependent Claim 16 words

A container as claimed in Claim 12 wherein the or a flexible sheet member is transparent.

Claim 15

Dependent Claim 16 words

A container as claimed in any preceding claim having an inlet opening and an exit opening.

Dependent Claim 22 words

A collapsible container substantially as hereinbefore described with reference to and as illustrated in Figures 5 to 13 of the accompanying drawings.

Claim 17

Dependent Claim 22 words

A collapsible container substantially as hereinbefore described with reference to and as illustrated in Figures 5 to 13 of the accompanying drawings.

Claim 18

Independent Claim 123 words

A method for forming a compartmented collapsible container which method comprises, pinching at least one flexible sheet member between opposed first and second members, said flexible sheet member and one of said opposed members, or a pair of said flexible sheet members, defining together the interior space of the container, said first member providing a plurality of ridges arranged to define boundaries of the desired compartments and said second member 65 70 75 80 85 90 95 100 105 110 115 120 125 6 GB 2 093 800 A 6 providing a planar surface or surfaces against which the said ridges sealingly compress said flexible sheet member or members, some or all of said ridges having gaps therein defining 5 passageways between compartments.

Claim 19

Independent Claim 123 words

A method for forming a compartmented collapsible container which method comprises, pinching at least one flexible sheet member between opposed first and second members, said flexible sheet member and one of said opposed members, or a pair of said flexible sheet members, defining together the interior space of the container, said first member providing a plurality of ridges arranged to define boundaries of the desired compartments and said second member 65 70 75 80 85 90 95 100 105 110 115 120 125 6 GB 2 093 800 A 6 providing a planar surface or surfaces against which the said ridges sealingly compress said flexible sheet member or members, some or all of said ridges having gaps therein defining 5 passageways between compartments.

Claim 20

Dependent Claim 22 words

A method as claimed in Claim 16 wherein the container formed is as claimed in any one of Claims 1 to 15.
