11 . A container system as set forth in claim 1 , wherein the lid is configured to form a seal with the mouth.

12 . A container system as set forth in claim 1 , wherein the lid includes a collar configured to be received over the mouth when the lid is screwed onto the mouth.

13 . A container system as set forth in claim 1 , further comprising a plurality of retainers circumferentially arranged on one of the mouth or the lid, the retainers circumferentially spaced apart to define a plurality of gaps, each gap disposed between adjacent retainers, and further comprising a plurality of catches circumferentially arranged on the other one of the mouth or the lid, each catch arranged to pass through one of the gaps to screw the lid on the mouth and arranged to engage one of the retainers when the lid is rotated relative to the mouth to screw the lid on the mouth.

14 . A container system as set forth in claim 1 , wherein the lid comprises a cover and a circumferential wall extending from the cover, the wall having an inner surface, the lid further comprising a plurality of catches extending radially inward from the inner surface of the wall, the catches being circumferentially spaced apart on the wall, and the lid comprising a locker to inhibit the lid from rotating relative to the container, the locker being moveable between an unlocked position and a locked position.

15 . A container system as set forth in claim 1 , wherein the mouth comprises a base and a circumferential wall extending from the base, the wall having an outer surface and an inner surface, the inner surface defining a mouth opening, and the mouth comprising a plurality of retainers circumferentially arranged on the outer surface of the wall, the retainers circumferentially spaced apart to define gaps between adjacent retainers, the retainers and gaps having an asymmetrical circumferential arrangement on the wall.

16 . A lid for a phosphorous pentasulfide container, the lid comprising:

a cover including a body, a circumferential wall extending from the body and having an inner surface and an opposing outer surface, a plurality of catches extending radially inward from the inner surface of the circumferential wall, the plurality of catches being circumferentially spaced apart on the circumferential wall, and a plurality of projections extending radially away from the outer surface of the circumferential wall, the body, the circumferential wall, the plurality of catches, and the plurality of projections of the cover integrally formed of the same piece of material, and at least one projection of the plurality of projections having a surface defining a channel; and

a locker configured to inhibit the lid from rotating relative to the container, the locker including a first pin being moveable between an unlocked position and a locked position and a second pin extending traverse to the first pin, the second pin movable to align with the channel of the projection to permit the first pin to move to the locked position and to misalign with the channel of the projection to inhibit the first pin to move to the locked position, wherein in the unlocked position the first pin is positioned to be disengaged from the container when the cover is on the container, and wherein in the locked position the first pin is positioned to engage the container when the cover is on the container.

17 . A lid as set forth in claim 16 , wherein the plurality of catches have an asymmetrical circumferential spacing arrangement on the wall to limit connection between the lid and the container to one orientation.

18 . A container system for holding a material, the container system comprising:

a container having an interior sized and shaped to hold the material, the container having a mouth defining a generally circular opening for communication with the interior;

a lid sized and shaped to block the opening; and

a closure configured to releasably connect the lid and the mouth, the closure including a plurality of elongated retainers circumferentially arranged on one of the mouth or the lid, the elongated retainers circumferentially spaced apart to define a plurality of gaps, each elongated retainer having a first end, a second end opposing the first end, and a ramp surface extending between the first end and the second end, the first end and the second end of each elongated retainer extending different distances from the mouth or the lid, each gap disposed between the first end and the second end of adjacent elongated retainers, the closure including a plurality of catches circumferentially arranged on the other one of the mouth or the lid, each catch arranged to pass through one of the gaps to mount the lid on the mouth and arranged to engage one of the elongated retainers when the lid is rotated relative to the mouth to secure the lid to the mouth, the catches and gaps each having an asymmetrical circumferential arrangement to limit connection between the lid on the mouth to one orientation.
