A recently filed patent (Publication Number: US20230265949A1) describes an assembly that includes a coupling member, a blanking cap, a seal, and a clamp. The coupling member has a first annular connection flange, while the blanking cap has a second annular connection flange. These connection flanges overlap and have opposing sealing faces, with the seal placed between them. The clamp is used to secure the connection flanges, seal, and blanking cap together. The blanking cap also features a pair of safety lugs that limit axial movement of the blanking cap away from the coupling member.

The first connection flange of the coupling member has two radial faces, with one of them serving as a sealing face. The safety lugs on the blanking cap are designed to engage with the second radial face of the first connection flange. When the connection flanges and seal are clamped together, the abutments of the safety lugs are spaced from the first connection flange, forming a seal. However, if the clamp is removed or released, the blanking cap can move axially away from the coupling member, breaking the seal.

The safety lugs on the blanking cap are equipped with stop members that define the abutments. These stop members can be elongate members that extend tangentially or curve about the central axis of the assembly. Additionally, the blanking cap can be attached to the coupling member or another fixed anchor point using a tether.

The assembly described in the patent can be used in various applications, including containers that hold powder and pressurized gas. The coupling member can be a tri-clamp ferrule, and the clamp can be a tri-clamp as well.

Overall, this patent describes an assembly with a coupling member, blanking cap, seal, and clamp, along with safety lugs that limit axial movement and ensure a secure seal. The design allows for easy removal and reattachment of the blanking cap while maintaining a reliable seal.
