Abstract
Abstract A multi-dose container for radio-isotopes comprises a body having a cover. The cover contains a slidable portion which opens to reveal a small opening for withdrawing the contents of the container. The slidable portion is spring loaded and locks in the open position by engaging holding means formed on the cover. The cover contains a release bar which, when pressed, removes the holding means from engagement with the slidable portion and allows the spring to return the slidable portion to a closed position. The operation can easily be performed with one hand.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A multi-dose container for radio isotopes, said container comprising a first hollow body formed of a material substantially impervious to radiation and having a first cover sealed thereto, said first cover being substantially impervious to radiation and having a formed depression in the upper surface thereof, said depression containing a first aperture communicating with the interior of said first body; a second body having a hollow cavity formed to receive said first body; a second cover for closing said second body; a dependent boss formed on the interior surface of said second cover, said boss having a configuration formed to match the formed depression in said first cover; a second aperture in said boss in alignment with said first aperture; a slidable portion formed to engage an opening in the upper surface of said second cover; and slidable portion holding and releasing means on said second cover.
Claim 2
Dependent Claim
147 words
A multi-dose container for radio isotopes, said container comprising a first hollow body formed of a material substantially impervious to radiation and having a first cover sealed thereto, said first cover being substantially impervious to radiation and having a formed depression in the upper surface thereof, said depression containing a first aperture communicating with the interior of said first body; a second body having a hollow cavity formed to receive said first body; a second cover for closing said second body; a dependent boss formed on the interior surface of said second cover, said boss having a configuration formed to match the formed depression in said first cover; a second aperture in said boss in alignment with said first aperture; a slidable portion formed to engage an opening in the upper surface of said second cover; and slidable portion holding and releasing means on said second cover.
Claim 3
Dependent Claim
42 words
The container of claim 1 wherein said slidable portion holding and releasing means comprises a pair of spaced projections extending from said second cover, said projections having a raised section on a surface thereof and a release bar connected between said projections.
Claim 4
Dependent Claim
39 words
The container of claim 2 wherein said slidable portion has ramped indentations formed on an underside thereof for cooperating with said raised sections to maintain said slidable portion in an open position whereby access to said apertures is available.
Claim 5
Dependent Claim
12 words
The container of claim 3 wherein said slidable portion is spring loaded.
Claim 6
Dependent Claim
19 words
The container of claim 4 wherein said slidable portion has a spring retaining stud formed on the underside thereof.
Claim 7
Dependent Claim
38 words
The container of claim 5 wherein said spring loading is accomplished by a linear wire spring having a coiled center section which engages said stud and oppositely extending arms which engage an interior wall of said second cover.
Claim 8
Dependent Claim
33 words
The container of claim 6 wherein said slidable portion is formed with a keyway and opposite walls of said opening in the upper surface of said second cover form keys for cooperation therewith.
Claim 9
Dependent Claim
29 words
The container of claim 7 wherein said slidable portion has a bottom surface which closes said aperture in said boss when said slidable protion is in the closed position.
Claim 10
Dependent Claim
60 words
The container of claim 8 wherein said movement of said slidable portion from a closed position to an open position increases tension in said spring and movement of said release bar in a direction away from said slidable portion disengages said raised sections from said ramped indentations and allows said spring to return said slidable portion to said closed position.
