Claim 5

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluidtight end closure, a projection having cutting terminal surfaces and flap-restraining means extending from said end closure inwardly into said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the inner container, the walls of said outer container being longitudinally compressible whereby upon compression of said outer container said sharp projection is compelled toward and into said imperforate end closure and said restraining means holds open flaps cut in said end closure causing said flaps to project downwardly into the interior of said inner container, said flaps being cut by terminal surfaces of said projection to establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers.

Claim 6

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluidtight end closure, a projection having cutting terminal surfaces and flap-restraining means extending from said end closure inwardly into said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the inner container, the walls of said outer container being longitudinally compressible whereby upon compression of said outer container said sharp projection is compelled toward and into said imperforate end closure and said restraining means holds open flaps cut in said end closure causing said flaps to project downwardly into the interior of said inner container, said flaps being cut by terminal surfaces of said projection to establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers.

Claim 7

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluidtight end closure, a projection having cutting terminal surfaces and flap-restraining means extending from said end closure inwardly into sAid outer container, said end closure also being provided with an outwardly extending dispensing tip, threadably connected to said tip a removable cap which also forms a seal on said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the outer container, the walls of said outer container being longitudinally compressible whereby upon compression of said outer container said sharp projection is compelled toward and into said imperforate end closure and said restraining means holds open flaps cut in said end closure causing said flaps to project downwardly into the interior of said inner container, said flaps being cut by terminal surfaces of said projection to establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers.

Claim 8

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluidtight end closure, a projection having cutting terminal surfaces and flap-restraining means extending from said end closure inwardly into sAid outer container, said end closure also being provided with an outwardly extending dispensing tip, threadably connected to said tip a removable cap which also forms a seal on said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the outer container, the walls of said outer container being longitudinally compressible whereby upon compression of said outer container said sharp projection is compelled toward and into said imperforate end closure and said restraining means holds open flaps cut in said end closure causing said flaps to project downwardly into the interior of said inner container, said flaps being cut by terminal surfaces of said projection to establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers.

Claim 9

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluid tight end closure, a dispensing spout extending from said end closure, a cover encasing said spout and said end closure and joined to said spout by a threaded connection, a projection comprising blades having cutting terminal surfaces and retaining notches, and flap-restraining means, said projection extending from said end closure inwardly into said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the outer, the walls of said outer container having a series of flexible undulations in proximity to its closed end to provide longitudinal compressibility of said outer container, whereby upon compression of said outer container said sharp projection is compelled toward and said blades pierce said imperforate end closure, said restraining means holds open flaps cut in said end closure by said cutting terminal surfaces to cause said flaps to project downwardly into said inner container and establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers, and said retaining notches hold said projection in said end closure after release of compression.

Claim 10

A self-contained, two-compartment mixing device comprising an outer container adapted to contain fluid having a fluid tight end closure, a dispensing spout extending from said end closure, a cover encasing said spout and said end closure and joined to said spout by a threaded connection, a projection comprising blades having cutting terminal surfaces and retaining notches, and flap-restraining means, said projection extending from said end closure inwardly into said outer container, an inner container completely received in said outer container, said inner container having an imperforate end closure, said end closure of said inner container facing said end closure of said outer container to isolate the contents of the inner container from the contents of the outer, the walls of said outer container having a series of flexible undulations in proximity to its closed end to provide longitudinal compressibility of said outer container, whereby upon compression of said outer container said sharp projection is compelled toward and said blades pierce said imperforate end closure, said restraining means holds open flaps cut in said end closure by said cutting terminal surfaces to cause said flaps to project downwardly into said inner container and establish fluid communication between said inner and outer containers to provide mixing of the contents of said containers, and said retaining notches hold said projection in said end closure after release of compression.
