Abstract
A disposable dispensing capsule for a plant injectable liquid composition includes a flexible cap hermetically sealed to a receptacle. The capsule is pressurized when the cap is forcibly flexed inwardly. In one embodiment flexure and thereby pressurization are maintained by an interference fit between a spindle in the receptacle and a socket depending downwardly from the cap central portion. In another embodiment flexure is maintained by engagement of hook-shaped posts in the receptacle with a lip in a collar depending downwardly from the cap central portion.
Claims16
A plant injection dispensing capsule comprising:
- a receptacle having a floor, and a circumferential wall generally orthogonal to the floor and terminating upwardly in a rim, the receptacle containing a preselected amount of a therapeutic liquid composition;
- a cap having a central portion, a flexible portion symmetric about the central portion, and a circumferential edge hermetically sealed to said rim;
- and
- means for maintaining inward flexure of the flexible portion, thereby keeping the capsule pressurized.
A plant injection dispensing capsule comprising:
- a receptacle having a generally planar floor, and a circumferential, generally cylindrical wall generally orthogonal to the floor and terminating upwardly in a circumferential, generally circular rim, the wall having an aperture proximate to the floor and sealed by a dislodgeable membrane, the floor having a channel proximate to the aperture, the receptacle containing a preselected amount of a therapeutic liquid composition;
- and
- a cap having a rigid central portion circumscribed by a plurality of concentric annuluses bridged consecutively pairwise by a plurality of stepped ridges, the ridges generally orthogonal to the annuluses so that the cap initially is convexly arcuate, the cap further having a circumferential, generally circular edge hermetically sealed to said rim, the cap flexing inwardly when a downward force is applied to the central portion, thereby pressurizing the capsule.
