The container with a lid attached to a threaded closure mechanism includes a receptacle having a mouth surrounded by a thread, a lid, a sealing ring and a closure mechanism formed by a disc with a hollow interior and a perimetral tubular skirt provided with an engagement configuration complementary to the thread of the receptacle. The closure mechanism surrounds the lid and holds it against the mouth of the receptacle by means of a threaded attachment between the engagement configuration of the closure mechanism and the thread of the receptacle, assuring proper hermetic closure of the lid with the receptacle in cooperation with the sealing ring and a retainer element connected to the closure mechanism to constrict an insertion passage thereof thereby retaining the lid into the closure mechanism.

The container with a lid and threaded closure mechanism includes a receptacle having a mouth surrounded by a thread, a lid, a sealing ring and a closure mechanism formed by a disc with a hollow interior and a perimetral tubular skirt provided with an engagement configuration complementary to the thread of the receptacle. The closure mechanism surrounds the lid and holds it against the mouth of the receptacle by means of a threaded attachment between the engagement configuration of the closure mechanism and the thread of the receptacle, assuring proper hermetic closure of the lid with the receptacle in cooperation with the sealing ring. The lid and the closure mechanism have mutually engaging elements with a complementary non-circular geometry and size, with both elements being tightly fitted preventing relative rotation of the closure mechanism with respect to the lid.

A manway cover assembly can be used to control access to the interior of a railroad tank car or other type of tank or structure. The manway cover assembly can have a tightening system, such as a screw tightening system and an attachment system. The attachment system can have a ledge configured to engage a flange that surrounds an opening. A cover can control access to the opening. The tightening system can secure the ledge to the flange and lock the cover over the opening. A manway cover assembly can also be used for selectively sealing an access passageway of a tank. The manway cover assembly can have an internal seal that remains sealed independent of movement between the cover and the opening within a set range of movement.

The container with a hermetic closure has a receptacle having a receptacle opening surrounded by an annular mouth surface, a lid having a front side and a back side intended for being oriented towards the outside and the inside of the receptacle, respectively, a sealing ring arranged between the annular mouth surface of the receptacle and an annular perimetral flange of the lid, and a closure mechanism formed by a shaped metal wire defining a first region coupleable to the lid, a second region being under elastic stress in a closed position and a third region coupleable to the receptacle. The front side of the lid has at least two opposite supporting points in an area coinciding with or adjacent to the annular flange, and the first region of the closure mechanism is configured for being supported, in a closed position, on said at least two opposite supporting points.

A container and method include a bowl having an interior for storing a substance, an openable lower lid for accessing the substance when the lower lid is in an open configuration, and an upper lid for retaining the substance within the interior of the bowl and the lower lid. The lower lid in the open configuration is replaceable and resealable using an adhesive to be in a closed configuration, with the substance sealed within the bowl. The bowl, the lower lid, and the upper lid are composed of a biodegradable or recyclable material. A ring is disposed under a lip of the bowl and engageable with the upper lid for establishing a child-resistant engagement between the upper lid and the bowl. An intermediate lid pushes against an engagement surface of the bowl for locking the upper lid

The present invention is directed to a child resistant double seam container lid including an adapter ring for securely affixing to the double seam top rim of conventional double seamed containers that will be difficult for children to open, yet readily openable by adults. More particularly, a one-piece, two-piece, and three-piece child resistant double seam affixable container lid is provided having a first piece lid portion first, a second piece adapter ring locking member second piece and optionally a third piece securing unit piece, with rotational alignment indicators, and optional additional integral features such as a liquid measuring cup feature, a liquid tight lid feature, a threaded lid portion, a replaceable double seam container lid portion and a double seam container lid locking member adapter ring securely affixable to the double seam container.
