Abstract
Abstract A mixing container structure is disclosed for use in shipping two materials such as two fluids so that these two materials are separated from one another. This structure includes an outer container for one of these materials and an inner container for the other of these materials located within the outer container. The top of the inner container fits closely within so as to form a seal with the interior of the neck of the outer container. A closure member is located on the outer container so that the skirt on this closure member fits closely within and forms a seal against the interior of the neck on the outer container. The closure member is capable of being moved so that this skirt forces the inner container into the interior of the outer container so that the materials within these containers can mix.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A mixing container structure which includes: an outer container having an internally tubular neck; an inner container having an externally tubular top; said inner container fitting within said outer container and said top fitting within said neck so that a seal is formed between said top and said neck; a closure member having a dependent tubular skirt; said closure member being located on said outer container with said skirt fitting within said tubular neck so as to form a seal therewith; said closure member being capable of being moved without being disassembled from said outer container so that said skirt abuts against said top of said inner container so as to force said top out of engagement with said neck of said outer container so as to release said inner container from said outer container within the interior of said outer container.
Claim 2
Dependent Claim
142 words
A mixing container structure which includes: an outer container having an internally tubular neck; an inner container having an externally tubular top; said inner container fitting within said outer container and said top fitting within said neck so that a seal is formed between said top and said neck; a closure member having a dependent tubular skirt; said closure member being located on said outer container with said skirt fitting within said tubular neck so as to form a seal therewith; said closure member being capable of being moved without being disassembled from said outer container so that said skirt abuts against said top of said inner container so as to force said top out of engagement with said neck of said outer container so as to release said inner container from said outer container within the interior of said outer container.
Claim 3
Dependent Claim
33 words
A mixing container structure as claimed in claim 1 including: a dispensing closure having a spout capable of being rotated between open and closed positions, said closure being located on said closure member.
Claim 4
Dependent Claim
33 words
A mixing container structure as claimed in claim 1 including: cooperating sealing means and positioning means located on the exteriors of said top and said skirt and on the interior of said neck.
Claim 5
Dependent Claim
92 words
A mixing container structure as claimed in claim 3 wherein: said cooperating sealing means comprise external annular projections located on the exterior of said top and the exterior of said neck and annular grooves located on the interior of said neck, said projections normally fitting within said groove, said projection on said skirt capable of fitting within the groove normally occupied by said projection on said top when said closure member has been moved so as to force said inner container top out of engagement with said neck and said outer container.
Claim 6
Dependent Claim
26 words
A mixing container structure as claimed in claim 1 including means on said closure member for limiting movement of said closure member towards said outer container.
Claim 7
Dependent Claim
21 words
A mixing container structure as claimed in claim 5 wherein: said means is an annular flange located on said closure member.
Claim 8
Dependent Claim
36 words
A mixing container structure as claimed in claim 1 including: spacer means located between said neck of said outer container and said closure member for preventing accidental movement of said closure member towards said outer container.
Claim 9
Dependent Claim
27 words
A mixing container structure as claimed in claim 7 wherein: said spacer means is a spacer member and is capable of being removed from said container structure.
Claim 10
Dependent Claim
86 words
A mixing container structure as claimed in claim 8 wherein: said spacer member is a band formed integrally with said closure member; said band including a tab projecting from said closure member and being attached to said closure member by an annular web of material which is sufficiently thin so as to be capable of being easily broken; said closure member also including a strip of reduced cross section which is sufficiently thin to be broken extending completely across said closure member adjacent to said tab.
Claim 11
Dependent Claim
267 words
A mixing container structure as claimed in claim 1 including: a dispensing closure having a spout capable of being rotated between open and closed positions, said closure being located on said closure member; cooperating sealing means and positioning means located on the exteriors of said top and said skirt and on the interior of said neck; said cooperating sealing means comprise external annular projections located on the exterior of said top and the exterior of said neck and annular grooves located on the interior of said neck, said projections normally fitting within said groove, said projection on said skirt capable of fitting within the groove normally occupied by said projection on said top when said closure member has been moved so as to force said inner container top out of engagement with said neck and said outer container; means on said closure member for limiting movement of said closure member towards said outer container; said means is an annular flange located on said closure member; spacer means located between said neck of said outer container and said closure member for preventing accidental movement of said closure member towards said outer container; said spacer member is a band formed integrally with said closure member; said band including a tab projecting from said closure member and being attached to said closure member by an annular web of material which is sufficiently thin so as to be capable of being easily broken; said closure member also including a strip of reduced cross section which is sufficiently thin to be broken extending completely across said closure member adjacent to said tab.
