Claim 7

The device of claim 4 wherein the closing means comprises a closure member releasably attached to an outer end of the barrier member and closing the channel from the atmosphere.

Claim 8

The device of claim 4 wherein the engaging means comprises a resilient sealing member positioned intermediate the barrier member and container in the container opening.

Claim 9

The device of claim 4 wherein the engaging means comprises a resilient outer end portion of the barrier member.

Claim 10

The device of claim 4 wherein said wall means defines passageway means having an inner end communicating with an inner end of the channel spaced outwardly relative the opening means, and having an outer end communicating with an upper portion of the chamber when said barrier member is in said operative position.

Claim 11

The device of claim 4 wherein said wall means defines said opening means at the inner end of the barrier member, and in which said inner end of the barrier member is spaced from the container lower wall when said barrier member is in said operative position.

Claim 12

The device of claim 4 wherein said wall means has an inner cylindrical section.

Claim 13

The device of claim 4 wherein said barrier member has an outer end defining an enlarged portion of the channel.

Claim 14

An irrigation solution device, comprising: a syringe having a barrel and a tip; a container having sidewalls and a lower wall at least partially defining a solution receiving chamber, and an opening adjacent an upper portion of the container; an elongated barrier member having wall means defining a channel to receive the syringe barrel and at least partially defining opening means adjacent an inner end of the barrier member, said barrier member being insertable through the container opening into an operative position with the inner end of the barrier member located adjacent the container lower wall, said channel having a width slightly larger than the syringe barrel to closely receive the syringe barrel while permitting passage of air between the atmosphere and said opening means, and said barrier member having a sufficient length to substantially cover the syringe barrel when positioned in said channel; means for releasably closing an outer end portion of the barrier member; means for sealingly engaging the barrier member to the container in said container opening responsive to insertion of the barrier member into the container; and means for releasably sealing the syringe to an outer portion of the barrier member and closing an inner portion of the channel to the atmosphere, said sealing means comprising an annular enlargement on an outer portion of the syringe barrel and a ledge on an outer portion of the barrier member having aperture means communicating between opposed inner and outer portions of the channel relative said ledge, said syringe enlargement resting on said ledge when the syringe is located at a first position in the channel with air passing between the atmosphere through the aperture means to said opening means, and said syringe enlargement sealingly engaging against the barrier member inwardly of said ledge to close an inner portion of said channel from the atmosphere when said syringe is inserted to a second sealing position in the barrier member inwardly relative said first position.

Claim 15

An irrigation solution device, comprising: a syringe having a barrel and a tip; a container having sidewalls and a lower wall at least partially defining a solution receiving chamber, and an opening adjacent an upper portion of the container; an elongated barrier member having wall means defining a channel to receive the syringe barrel and at least partially defining opening means adjacent an inner end of the barrier member, said barrier member being insertable through the container opening into an operative position with the inner end of the barrier member located adjacent the container lower wall, said channel having a width slightly larger than the syringe barrel to closely receive the syringe barrel while permitting passage of air between the atmosphere and said opening means, and said barrier member having a sufficient length to substantially cover the syringe barrel when positioned in said channel; means for releasably closing an outer end portion of the barrier member; means for sealingly engaging the barrier member to the container in said container opening responsive to insertion of the barrier member into the container; and means for releasably sealing the syringe to an outer portion of the barrier member and closing an inner portion of the channel to the atmosphere, said sealing means comprising an annular enlargement on an outer portion of the syringe barrel and a ledge on an outer portion of the barrier member having aperture means communicating between opposed inner and outer portions of the channel relative said ledge, said syringe enlargement resting on said ledge when the syringe is located at a first position in the channel with air passing between the atmosphere through the aperture means to said opening means, and said syringe enlargement sealingly engaging against the barrier member inwardly of said ledge to close an inner portion of said channel from the atmosphere when said syringe is inserted to a second sealing position in the barrier member inwardly relative said first position.
