A container lid and lock ring combination includes a lid for a container and a lock ring configured to extend loosely around the lid. The lock ring is configured to be tightened for securing the lid to a container. A joint connects the lid and the lock ring to one another.

A closure is provided for a pressure vessel or pipelines that can provide quick and easy access to the interior of a pressure vessel or pipeline and means for a pressure tight seal between the hub and door. The closure can incorporate means for mechanically fastening the door to the hub using an external split clamp ring actuated by a toggle mechanism. A locking mechanism can be provided to safeguard against unintended closure actuation and provides a layer of redundancy to the holding characteristics of the toggle mechanism. The locking mechanism can be interlocked to a pressure alert system to ensure any differential pressure condition contained within the closure is detected prior to disengaging the locking mechanism and actuating the toggle mechanism.

A claim ring for a lid, components thereof, and associated methods. The clamp ring is configured to maintain a lid on a mouth of a container to form a seal therebetween. The clamp ring includes a clamping mechanism including a wheel and a pull. The wheel is turnable to pull the pull to draw end portions of the clamping ring toward each other. A tool receiver can be engaged by a tool and turned by the tool to turn the wheel with the mechanical advantage of the tool.

Disclosed is a lid (10) for closing a receptacle (20), the lid comprising: a static portion (18) arranged to substantially match an opening of the receptacle to be closed; a plurality of pivoting arms (11) coupled to the static portion; means (12) for moving the plurality of pivoting arms between a first position wherein the plurality of pivoting arms lie within a perimeter of the static portion and a second position wherein the plurality of pivoting arms lie outside a perimeter of the static portion and engage with a complementary feature of the receptacle.

An apparatus for a sterile transfer of a material incudes a second safety device which locks an actuation mechanism in a closed position and unlocks the actuation mechanism when a container flange is correctly connected to a port flange, a third safety device which locks the container flange connected to the port flange when the actuation mechanism leaves the closed position, and a fourth safety device which blocks a return of the actuation mechanism from the open position to the closed position when the port door is open. The second, third and/or fourth safety device comprises two magnetic elements with at least one closed wall being arranged between the two magnetic elements. The two magnetic elements are configured to mutually attract or to mutually repel through the at least one closed wall either in a lock position or in an unlock position of the second, third and/or fourth safety device.

A bottle stopper contains: a first connection part, a second connection part, an actuation member, an operation unit, a fitting sleeve, and a base. The first connection part includes two opposite cutouts. The second connection part includes an aperture. The actuation member includes an extension sheet, a post, and a threaded portion. The operation unit includes two projections and a drive element, wherein each of the two projections is a cuboid, and two distal ends of the drive element are connected with two eccentric positions of two outer surfaces of the two projections respectively. The fitting sleeve is hollow and is fitted on the post below a bottom of the second connection part. The base includes a screwing orifice for screwing with the threaded portion of the actuation member, and the fitting sleeve is fitted on the base.

The present invention relates to a closing ring closure device (10) fora closing ring (12) with a closing lever (14) and a one-piece or two-piece traction bracket (16), each of which are pivotably mounted by means of pivot bearings (18, 20) on a pivot bearing base (22, 24) on the closing ring side, wherein the traction bracket (16) and the closing lever (14) are pivotably connected to one another by means of a further pivot bearing (26). For automation in production technology and for the use of mechanical closing ring closure devices, e.g. on automatic filling lines, it is very advantageous if the two components closing lever (14) and traction bracket (16) are provided with special constructive means which are designed in a mutually coordinated functional mode between the two components as a snap-fit device for fixing the closing ring closure device (10) in wide-open closing lever position.
