Apparatus for injecting plants

Claim 2

A two component, telescopically compressible, hollow container for plant injectible fluid compositions, wherein a hermetic sealing means extends between the telescopic portions of said container to prevent leakage through capillary film formation.

Claim 3

The two component container of claim 1 wherein said hermetic sealing means are defined by at least one peri--metrical ridcre.

Claim 4

The two component container of claim 1 wherein said hermetic sealing means are defined by a plurality of perimetrical ridges.

Claim 5

The two component container of claim 3 wherein said perimetrical ridges have an outwardly projecting configura- tion of diminishing cross-section.

Claim 6

The two component container of claim 1 wherein said components are telescopically compressible from an outer position of an enlarged interior volume to an inner position of reduced interior volume and said hermetic sealing means are defined by a plurality of perimetrical ridges which project outwardly from a first of said container components into positj engagement with a second of said container components with said plurality of ridges including an uppermost perimetrical ridge that projects outwardly to a lesser extent than the other ridges in said plurality of ridges, and wherein said hermetic sealing means further includes a single perimetrical ridge thad projects outwardly from the second of said container component into positive engagement with the first of said container components at a locus proximate to said uppermost ridge when said container is disposed in the outer position.

Claim 7

A variable volume hollow container for plant injectible fluid compositions comprising: a pair of opposing cup-like body portions having interfitting and mutually slidable sidewalls, with said body portions cooperatively defining a single, undivided interior volume for releasable containment of a pressurized plant injectible fluid composition; stop means at outer and inner axially spaced positions on the mutually slidable sidewalls of said body portions, with said outer position defining an enlarged interior volume for said container and said inner position defining a reduced interior volume for said container, whereby relative movement of said body portions from said outer position to sa: inner position reduces the interior volume of said container effect pressurization of the fluid composition in said contai: discharge passage means, including penetrable diaphragm means, formed in one of said body portions to permit the discharge of pressurized fluid composition from the reduced interior volume of said container; and hermetic seal means extending between opposing faces of the mutually slidable sidewalls of said body portions to prevent leakage through capillary film formation.

Claim 8

A variable volume hollow container for plant injectible fluid compositions comprising: a pair of opposing cup-like body portions having interfitting and mutually slidable sidewalls, with said body portions cooperatively defining a single, undivided interior volume for releasable containment of a pressurized plant injectible fluid composition; stop means at outer and inner axially spaced positions on the mutually slidable sidewalls of said body portions, with said outer position defining an enlarged interior volume for said container and said inner position defining a reduced interior volume for said container, whereby relative movement of said body portions from said outer position to sa: inner position reduces the interior volume of said container effect pressurization of the fluid composition in said contai: discharge passage means, including penetrable diaphragm means, formed in one of said body portions to permit the discharge of pressurized fluid composition from the reduced interior volume of said container; and hermetic seal means extending between opposing faces of the mutually slidable sidewalls of said body portions to prevent leakage through capillary film formation.

Claim 9

The container of claim 6 wherein one of said body portions defines a closure having a substantially cylindrical sidewall and the other of said body portions defines a receptacle having inner and outer substantially cylindrical sidewalls in spaced relationship with said spaced relationship defining an annular space for slidably receiving the sidewall of said closure.

Claim 10

The container of claim 7 wherein said stop means are incorporated onto the outer surface of the closure sidewall and onto the inner surface of the receptacle outer sidewall..

Claim 11

The container of claim 8 wherein the hermetic sealing means extend between the inner surface of the closure sidewall and the outer surface of the receptacle inner sidewall.

Claim 12

The container of claim 9 wherein the hermetic . sealing means comprise at least one circumferential ridge.

Claim 13

The container of claim 10 wherein the hermetic sealing means comprise a plurality of circumferential ridges.

Claim 14

The container of claim 11 wherein said plurality of circumferential ridges extend from the outer surface of the receptacle inner sidewall to the inner surface of the closure sidewall.

Claim 15

The container of claim 12 wherein said plurality of circumferential ridges includes an uppermost ridge which is closest to the open end of said receptacle and projects from the outer surface of the receptacle sidewall to a lesser extent than the other ridges in said plurality of ridges; and wherein a single circumferential ridge projects from the inner surface cf the closure sidewall to the outer surface of the receptacle inner sidewall at a locus proximate to said uppermost circumferential ridge when said body portions are disposed in the outer position.
