Barrier two part pairing and dispensing cartridge

Claim 2

A dual compartment container for separately storing two materials, subsequently mixing them, and later dispensing the mixture comprising: a cylindrical body having a sealable orifice at each end thereof; a barrier assembly disposed within the cylindrical body between the two ends for creating two separated compartments in the cylindrical body and capable of separating two materials, said barrier assembly having a sealing member having slidable, sealing contact with the inner wall of the cylindrical body and a dasher movable axially back and forth toward each of the ends to mix the material to be contained in the cylindrical body, the sealing member and the dasher being normally adjacent each other during the separate storing of the materials and during dispensing of the mixture; and wherein the improvement comprises: said sealing member having means for releasably engaging and disengaging the dasher, said means comprising a central sleeve orifice and a circumferential locking shoulder; said dasher having a means for releasably engaging and disengaging the sealing member, said means comprising a central core adapted for axial sliding engagement with the central sleeve orifice, and resilient locking members adapted to releasably engage the circumferential locking shoulder; and a means for moving the dasher comprising a rod attached to the dasher, said attachment allowing the rod to be positioned relative to the dasher in a first position which lockingly engages the dasher to the sealing member and in a second position which permits the dasher to be disengaged from the sealing member.

Claim 3

The container defined in claim 1 wherein said resilient locking members are circumferentially spaced about the leading end of the dasher's central core.

Claim 4

A dual compartment container for separately storing two materials, subsequently mixing them, and later dispensing the mixture comprising: a cylindrical body having a sealable orifice at each end thereof; a barrier assembly disposed within the cylindrical body between the two ends for creating two separated compartments in the cylindrical body and capable of separating two materials, said barrier assembly having a sealing member having slidable, sealing contact with the inner wall of the cylindrical body and a dasher movable axially back and forth toward each of the ends to mix the material to be contained in the cylindrical body, the sealing member and the dasher being normally adjacent each other during the separate storing of the materials and during dispensing of the mixture; means for axially moving said barrier assembly from one end of the cylindrical body to the other, and wherein the improvement comprises: said sealing member having means for releasably engaging and disengaging the dasher, said means comprising a central sleeve orifice and a circumferential locking shoulder; said dasher having a means for releasably engaging and disengaging the sealing member, said means comprising a central core adapted for axial sliding engagement with the central sleeve orifice, and resilient locking members adapted to releasably engage the circumferential locking shoulder, wherein said resilient locking members are circumferentially spaced about the leading end of the dasher's central core; and said moving means having a rod extending partially into the cylindrical body having one end terminating externally of the cylindrical body and attaching means on the end of the rod in the cylindrical body for attaching the internal end of the rod to the dasher, said attachment allowing the rod to be axially movable relative to the dasher between a first position and a second position, and the rod further comprises surface means integral with the rod for abutting the dasher's resilient locking members and for urging the locking members into locking engagement with the sealing member's circumferential locking shoulder when the rod is in the first position and for not abutting said resilient locking members when the rod is in the second position for permitting the resilient locking members to disengage the locking shoulder of the sealing means.

Claim 5

A dual compartment container for separately storing two materials, subsequently mixing them, and later dispensing the mixture comprising: a cylindrical body having a sealable orifice at each end thereof; a barrier assembly disposed within the cylindrical body between the two ends for creating two separated compartments in the cylindrical body and capable of separating two materials, said barrier assembly having a sealing member having slidable, sealing contact with the inner wall of the cylindrical body and a dasher movable axially back and forth toward each of the ends to mix the material to be contained in the cylindrical body, the sealing member and the dasher being normally adjacent each other during the separate storing of the materials and during dispensing of the mixture; means for axially moving said barrier assembly from one end of the cylindrical body to the other, and wherein the improvement comprises: said sealing member having means for releasably engaging and disengaging the dasher, said means comprising a central sleeve orifice and a circumferential locking shoulder; said dasher having a means for releasably engaging and disengaging the sealing member, said means comprising a central core adapted for axial sliding engagement with the central sleeve orifice, and resilient locking members adapted to releasably engage the circumferential locking shoulder, wherein said resilient locking members are circumferentially spaced about the leading end of the dasher's central core; and said moving means having a rod extending partially into the cylindrical body having one end terminating externally of the cylindrical body and attaching means on the end of the rod in the cylindrical body for attaching the internal end of the rod to the dasher, said attachment allowing the rod to be axially movable relative to the dasher between a first position and a second position, and the rod further comprises surface means integral with the rod for abutting the dasher's resilient locking members and for urging the locking members into locking engagement with the sealing member's circumferential locking shoulder when the rod is in the first position and for not abutting said resilient locking members when the rod is in the second position for permitting the resilient locking members to disengage the locking shoulder of the sealing means.

Claim 6

The container defined in claim 3 wherein: said container has only one sealable orifice at one end thereof; said rod passing through said one sealable orifice in a sliding and sealing relationship, the internal end of the rod being externally threaded.

Claim 7

The container defined in claim 3 wherein the attaching means on the internal end of the rod comprising an externally threaded end extending from the surface means, the dasher having an internally threaded opening in its central core extending inward from the resilient locking shoulder whereby the surface means of the rod abuts the resilient locking tabs when the external thread of the rod substantially fully engages the internally threaded opening of the central core.

Claim 10

The method defined in claim 6 further including: prior to positioning the dasher and the sealing member at the rear of the container, threading the rod into the dasher a sufficient amount to lock the dasher into its disengaged position; and prior to axially re-engaging the dasher with the sealing member, unthreading the rod out of the dasher a sufficient amount to unlock the dasher from its disengaged position.
