Abstract
Abstract The container closure system comprises a plug with an O-ring for cooperation with a frustoconical opening of the container; the plug is pivotally mounted on an axis at right angle to that of the opening on the body and a locking member is pivotally mounted on the plug about an axis located along a diameter of the plug. The locking member is adapted to engage a resilient bracket carried by the container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A container with a leaktight closure, comprising a body, a cylindrical chamber in said body having an opening coaxial with said chamber and bounded by a bearing surface, a sealing plug for application against said bearing surface, a hinge pin carried by said body and supporting said plug for pivotal movement about an axis at right angle to that of said chamber between a closed position and a position in which it completely clears said opening, a locking member rotatably mounted on the plug about an axis parallel to that of the hinge pin and substantially along a diameter of said plug, and a resilient bracket having a free end secured to the body against rotation relative thereto, at a location diametrically opposite to the hinge pin, sAid locking member having means cooperating with said bracket to exert on the locking member a force transverse to said axis of said chamber which forces the plug into said closed position when said plug is located in or near said position.
Claim 2
Dependent Claim
169 words
A container with a leaktight closure, comprising a body, a cylindrical chamber in said body having an opening coaxial with said chamber and bounded by a bearing surface, a sealing plug for application against said bearing surface, a hinge pin carried by said body and supporting said plug for pivotal movement about an axis at right angle to that of said chamber between a closed position and a position in which it completely clears said opening, a locking member rotatably mounted on the plug about an axis parallel to that of the hinge pin and substantially along a diameter of said plug, and a resilient bracket having a free end secured to the body against rotation relative thereto, at a location diametrically opposite to the hinge pin, sAid locking member having means cooperating with said bracket to exert on the locking member a force transverse to said axis of said chamber which forces the plug into said closed position when said plug is located in or near said position.
Claim 3
Dependent Claim
13 words
A container in accordance with claim 1, wherein said bearing surface is frustoconical.
Claim 4
Dependent Claim
102 words
The container of claim 1, for storage and shipping of radioactive samples in combination with a gamma shielding flask formed with a well of a diameter receiving said container, a holding plate secured to said plug in a position such that it is transverse to the axis of said chamber when said plug is in its closed position, said flask having a closure member for closing said well, said closure member being in close proximity to said holding plate when said flask is closed to constitute means preventing undesirable opening of said plug as long as said container is in said flask.
Claim 5
Dependent Claim
36 words
A container in accordance with claim 1, having an extension rod secured to the locking member in an orientation such that it is placed substantially along the axis of the body when the plug is closed.
Claim 6
Dependent Claim
24 words
A container in accordance with claim 4, characterized in that the extension rod is provided with a holding plate at the top end thereof.
Claim 7
Dependent Claim
70 words
A container in accordance with claim 5, characterized in that said holding plate has an overall width transversely to the axis of the same order as the overall width of the body in order to prevent any movement of rotation of the rod and opening of the container when said container is placed within a well which has a slightly larger diameter than the overall radial dimensions of the body.
Claim 8
Dependent Claim
141 words
A container, comprising: a body forming a chamber having an opening; a plug pivotally mounted on said body for rotation about a first axis between a closed position and an open position; a locking member pivotally mounted to said plug about a second axis parallel to and spaced from said first axis; a resilient link having a free end secured at said body against rotation relative thereto, said free end being secured at a location on the opposite side of the opening from said first axis; said locking member releasably pivotally engaging said link about a third axis parallel to and spaced from said first and second axes; said link, member and plug forming a toggle means moved over center during closing to position said second axis on the body side of a plane passing through said first and third axes.
Claim 9
Dependent Claim
141 words
A container, comprising: a body forming a chamber having an opening; a plug pivotally mounted on said body for rotation about a first axis between a closed position and an open position; a locking member pivotally mounted to said plug about a second axis parallel to and spaced from said first axis; a resilient link having a free end secured at said body against rotation relative thereto, said free end being secured at a location on the opposite side of the opening from said first axis; said locking member releasably pivotally engaging said link about a third axis parallel to and spaced from said first and second axes; said link, member and plug forming a toggle means moved over center during closing to position said second axis on the body side of a plane passing through said first and third axes.
