Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A package for the separate storage and mixing of different materials, said package comprising at least two independently formed compartments, each compartment receiving one of said materials therein and being separately sealed by a cap independently of the remaining compartments for an individual handling and processing of each compartment, said package further comprising an assembly of said compartments with the caps thereof in closely spaced direct alignment with each other, separate means both sealing said compartments to each other between the aligned caps and sealing the space between the aligned caps, and pusher means completely received and sealed within at least one compartment, said pusher means having a piercing end thereon for selective projection through the closely spaced aligned caps for a severing of said caps and a communication of the interiors of the compartments through the sealed space between the caps without affecting the means sealing said compartments to each other and without exposure of the pusher means outside of a sealed environment.
Claim 2
Dependent Claim
164 words
A package for the separate storage and mixing of different materials, said package comprising at least two independently formed compartments, each compartment receiving one of said materials therein and being separately sealed by a cap independently of the remaining compartments for an individual handling and processing of each compartment, said package further comprising an assembly of said compartments with the caps thereof in closely spaced direct alignment with each other, separate means both sealing said compartments to each other between the aligned caps and sealing the space between the aligned caps, and pusher means completely received and sealed within at least one compartment, said pusher means having a piercing end thereon for selective projection through the closely spaced aligned caps for a severing of said caps and a communication of the interiors of the compartments through the sealed space between the caps without affecting the means sealing said compartments to each other and without exposure of the pusher means outside of a sealed environment.
Claim 3
Dependent Claim
45 words
A package as defined in claim 1, wherein the compartment containing the pusher means is formed of a flexible material enabling an external manipulation of the pusher means, without access to the interior of this compartment, by a flexing of the material of the compartment.
Claim 4
Dependent Claim
40 words
A package as defined in claim 2, wherein the separate means sealing said compartments to each other comprises seals positioned between the compartments and about the aligned caps, and a crimping ring encircling the seals and engaged with the compartments.
Claim 5
Dependent Claim
25 words
A package as defined in claim 2, wherein the interiors of said compartments and the portion of the package between the aligned caps are sterile.
Claim 6
Dependent Claim
79 words
A package as defined in claim 2, wherein the flexible material compartment is cylindrical inwardly of the associated cap, said pusher means comprising a rigid hollow tubular member aligned within the cylindrical compartment and having perforating means on one end thereof directed toward the aligned caps, said pusher means further including a cylindrical skirt fixed to the tubular member in outwardly spaced surrounding relation thereto, said skirt being of a diameter slightly less than that of the cylindrical compartment.
Claim 7
Dependent Claim
42 words
A package as defined in claim 5, including a tab engaged with said pusher means for a selective immobilization thereof, said tab flexing upon the application of pressure to said pusher means so as to allow for movement of the pusher means.
Claim 8
Dependent Claim
83 words
A package as defined in claim 1, wherein three compartments are provided, the assembly of compartments comprising a central compartment having opposed ends, each sealed by a cap independently of the remaining compartments, the remaining two compartments having the caps thereof respectively in closely spaced alignemnt with the two caps of the central compartment to provide two sets of aligned caps, said pusher means being sealed within the central compartment and having opposed piercing ends thereon selectively projectible through both sets of caps.
Claim 9
Dependent Claim
31 words
A package as defined in claim 7 wherein said central compartment is of a flexible material enabling an external manipulation of the pusher means without requiring entry into the central compartment.
