Abstract
Abstract A compartmented package including an outer container having a side wall portion joining an outer closed end and an outer sealed fill end, the outer container defining a first chamber portion adjacent to the outer closed end and a second chamber portion adjacent to the outer fill end, the first and second chamber portions being spaced apart in a direction extending between the outer closed and fill ends and the outer container further defining a stop surface; a first fluid substance retained in the first chamber portion of said outer container; an inner container retained in the second chamber portion of the outer container and having an inner closed end and an inner sealed fill end, the inner container defining an abutment surface engaging the stop surface so as to prevent movement of the inner container into the first chamber portion of the outer container; and a second fluid substance retained in the inner container and sealed from the first fluid substance.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
190 words
A compartmented package comprising: an outer container having a side wall portion joining an outer closed end and an outer fill end with sealed together outer wall portions forming a fluid tight outer seal, said outer container defining a first chamber portion adjacent to said outer closed end and a second chamber portion adjacent to said outer fill end, said first and second chamber portions being spaced apart in a direction extending between said outer closed and fill ends, and said outer container further defining a stop surface; a first fluid substance retained in said first chamber portion of said outer container; an inner container retained in said second chamber portion of said outer container and having an inner closed end and an inner fill end with inner wall portions commonly sealed with said outer wall portions to form a fluid tight inner seal, said inner container defining an abutment surface engaging said stop surface so as to prevent movement of said inner container into said first chamber portion of said outer container; and a second fluid substance retained in said inner container and sealed from said first fluid substance.
Claim 2
Dependent Claim
190 words
A compartmented package comprising: an outer container having a side wall portion joining an outer closed end and an outer fill end with sealed together outer wall portions forming a fluid tight outer seal, said outer container defining a first chamber portion adjacent to said outer closed end and a second chamber portion adjacent to said outer fill end, said first and second chamber portions being spaced apart in a direction extending between said outer closed and fill ends, and said outer container further defining a stop surface; a first fluid substance retained in said first chamber portion of said outer container; an inner container retained in said second chamber portion of said outer container and having an inner closed end and an inner fill end with inner wall portions commonly sealed with said outer wall portions to form a fluid tight inner seal, said inner container defining an abutment surface engaging said stop surface so as to prevent movement of said inner container into said first chamber portion of said outer container; and a second fluid substance retained in said inner container and sealed from said first fluid substance.
Claim 3
Dependent Claim
17 words
A compartmented package according to claim 1 wherein said inner and outer sealed ends are heat sealed.
Claim 4
Dependent Claim
33 words
A compartmented package according to claim 1 wherein said inner and outer containers are formed from incompatible sealable materials and said inner sealed end is only partially encompassed by said outer sealed end.
Claim 5
Dependent Claim
17 words
A compartmented package according to claim 3 wherein said inner and outer sealed ends are heat sealed.
Claim 6
Dependent Claim
17 words
A compartmented package according to claim 1 wherein said inner and outer containers are flexible walled tubes.
Claim 7
Dependent Claim
39 words
A compartmented package according to claim 1 wherein said stop surface comprises a reduced inner dimensional section of said side wall portion of said outer container, and said abutment surface comprises an outer peripheral portion of said inner container.
Claim 8
Dependent Claim
37 words
A compartmented package according to claim 6 wherein said inner and outer containers are flexible walled tubes and said inner dimensions of said second chamber portion are substantially equal to the outer dimensions of said inner container.
Claim 9
Dependent Claim
26 words
A compartmented package according to claim 7 wherein said stop surfaces comprise an annular shoulder formed by a reduced diameter portion of said side wall portion.
Claim 10
Dependent Claim
43 words
A compartmented package according to claim 1 wherein said stop surface comprises said closed end of said outer container, and said abutment surface comprises a projection portion of said inner container extending from said closed end thereof and through said first chamber portion.
Claim 11
Dependent Claim
17 words
A compartmented package according to claim 9 wherein said inner and outer containers are flexible walled tubes.
Claim 12
Independent Claim
173 words
A method for producing a compartmented package comprising the steps of: forming an outer container having an outer closed end, an outer open end, a side wall portion joining said outer open and closed ends, and a stop surface; said outer container defining a first chamber portion adjacent to said outer closed end and a second chamber portion adjacent to said outer open end; forming an inner container having an inner closed end, an inner open end, and an abutment surface; filling said first chamber portion of said outer container with a first fluid substance; inserting said inner container into said second chamber portion of said outer container so as to produce engagement between said stop surface and said abutment surface; filling said inner container with a second fluid substance; and commonly sealing together inner wall portions and outer wall portions of, respectively, said inner and outer open ends to secure said inner container within said outer container and to seal said first and second substances, respectively, within said outer and inner containers.
Claim 13
Independent Claim
173 words
A method for producing a compartmented package comprising the steps of: forming an outer container having an outer closed end, an outer open end, a side wall portion joining said outer open and closed ends, and a stop surface; said outer container defining a first chamber portion adjacent to said outer closed end and a second chamber portion adjacent to said outer open end; forming an inner container having an inner closed end, an inner open end, and an abutment surface; filling said first chamber portion of said outer container with a first fluid substance; inserting said inner container into said second chamber portion of said outer container so as to produce engagement between said stop surface and said abutment surface; filling said inner container with a second fluid substance; and commonly sealing together inner wall portions and outer wall portions of, respectively, said inner and outer open ends to secure said inner container within said outer container and to seal said first and second substances, respectively, within said outer and inner containers.
Claim 14
Dependent Claim
45 words
