Abstract
Abstract A package in which two materials maintained in separated relation can be mixed and dispensed in which a liquid is preloaded in one member and a material to be taken up in the liquid in another member and the two members are joined to form a package in which the materials are maintained in their separated relation but in which the liquid can be transferred from the one member to the other without member separation for taking up the other material in solution or suspension.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
309 words
A package of measured amounts of two materials, at least one of which is a liquid, in which the materials are maintained in a separated relation in the package until substantially immediately prior to use and are admixed while still in the package from which the mixture of materials can be poured comprising a vial in the form of a test tube having an opening only at the top containing a measured amount of a material to be mixed with the liquid, a tubular member having a neck portion at the forward end with a passage extending continuously therethrough from the open rearward end to the open forward end, said tubular member being dimensioned to have a forward wall to wall dimension which is less than the wall to wall dimension of the vial, a sealing member on the neck portion of the tubular member dimensioned to engage the walls of the vial in sealing engagement when the tubular member is inserted in the open end portion of the vial as a stopper, sealing means closing the passage through the tubular member at the forward end portion to separate the passage of the tubular member from the material in the vial in normal position and to provide an open passage communicating the interior of the vial with the passage upon actuation to operative position in response to pressure from the liquid in the tubular member, a piston ring dimensioned slidably to be received in the passage of the tubular member, and means for actuating the piston ring from normal position in the rearward end of the passage to operated position in the forward end portion of the passage to force the liquid from the tubular member, the liquid in the tubular member being maintained in sealing relation within the tubular member between the sealing means and the piston ring.
Claim 2
Dependent Claim
309 words
A package of measured amounts of two materials, at least one of which is a liquid, in which the materials are maintained in a separated relation in the package until substantially immediately prior to use and are admixed while still in the package from which the mixture of materials can be poured comprising a vial in the form of a test tube having an opening only at the top containing a measured amount of a material to be mixed with the liquid, a tubular member having a neck portion at the forward end with a passage extending continuously therethrough from the open rearward end to the open forward end, said tubular member being dimensioned to have a forward wall to wall dimension which is less than the wall to wall dimension of the vial, a sealing member on the neck portion of the tubular member dimensioned to engage the walls of the vial in sealing engagement when the tubular member is inserted in the open end portion of the vial as a stopper, sealing means closing the passage through the tubular member at the forward end portion to separate the passage of the tubular member from the material in the vial in normal position and to provide an open passage communicating the interior of the vial with the passage upon actuation to operative position in response to pressure from the liquid in the tubular member, a piston ring dimensioned slidably to be received in the passage of the tubular member, and means for actuating the piston ring from normal position in the rearward end of the passage to operated position in the forward end portion of the passage to force the liquid from the tubular member, the liquid in the tubular member being maintained in sealing relation within the tubular member between the sealing means and the piston ring.
Claim 3
Dependent Claim
72 words
A package as claimed in claim 1 in which the sealing means on the neck end portion of the tubular member comprises a diaphragm spanning the open end of the passage at the forward end of the tubular member and having a passage which remains closed while the diaphragm is in normal position and which opens responsive to flexure of the diaphragm in response to liquid pressure from within the tubular member.
Claim 4
Dependent Claim
58 words
A package as claimed in claim 1 in which the sealing means comprises a sealing ring of flexible material within the forward end portion of the passage through the tubular member but rearward of the neck portion, and means for opening a passage through the sealing ring responsive to internal pressure from the liquid in the tubular member.
Claim 5
Dependent Claim
44 words
A package as claimed in claim 3 in which the sealing ring is formed with a slit through the central portion thereof which remains closed when in normal position and which opens in response to flexure of the ring in response to fluid pressure.
Claim 6
Dependent Claim
43 words
A package as claimed in claim 2 in which the passage in the diaphragm is in endwise alignment with the end portions of the tubular member for abutment with the neck flange to effect a sealing relation therewith when in normal seated position.
Claim 7
Dependent Claim
106 words
A package as claImed in claim 1 in which the sealing means comprises a sealing ring of flexible material within the forward end portion of the passage through the tubular member but rearward of the neck portion, a diaphragm extending crosswise of the sealing ring to seal off the passage, a support extending crosswise within the passage between the diaphragm and the shoulder formed by the neck portion of the tubular member and which engages the shoulder as a stop, a bayonet fixed to the support with the pointed end extending in the direction of the diaphragm for piercing the diaphragm responsive to internal fluid pressure.
Claim 8
Dependent Claim
23 words
A package as claimed in claim 2 in which the sealing member and diaphragm are of unitary construction of a flexible sealing material.
Claim 9
Dependent Claim
35 words
A package as claimed in claim 3 in which the sealing ring is formed of an elastomeric material having circular ribs dimensioned to extend into sealing engagement with the inner wall of the tubular member.
Claim 10
Dependent Claim
44 words
A package as claimed in claim 1 which includes means on the rearward end of the piston ring for attachment of an actuator and which includes an elongate actuator dimensioned to exceed the length of travel of the piston ring through the tubular member.
Claim 11
Dependent Claim
38 words
A package as claimed in claim 9 in which the actuator comprises an elongate rod dimensioned to be received in telescoping relation within the tubular member and with means for attachment of the actuator to the piston ring.
Claim 12
Dependent Claim
29 words
A package as claimed in claim 1 which includes flange members extending radially outwardly from the rearward end portion of the tubular member for use as a finger grip.
Claim 13
Dependent Claim
33 words
A package as claimed in claim 3 in which the sealing ring comprises a unitary disc member having a central body portion and rim portions of greater thickness than the central body portion.
Claim 14
Dependent Claim
43 words
A package as claimed in claim 3 in which the sealing ring comprises a pair of axially spaced rim portions, a tubular portion joining the inner areas of said rim portions and a disc portion spanning the tubular portion with a slit therethrough.
