Closure with lid and removable membrane

Abstract

A closure (GA,GB) is provided for a system with an opening. The closure (A,B) has a body (A,B) with an outer end (B) and a through passage (GB) for communicating with the system opening. The body (A,B) has a membrane (B) mitially occluding the through passage (B). The closure (A,B) has a lid (A.B) to accommodate movement relative to the body (A,B) between a closed position restricting access to the through passage (B) and an open position permitting greater access to the through passage (B). The body (A,B) thither has a separation member (GB) that can be engaged by a user to separate at least a part of the membrane (B) from the body (A.B). The separation member (B) extends away from the membrane (B) and has a deployed configuration wherein the separation member (B) projects outwardly beyond the body outer end (B) when the lid (A,B) is in the open position. The separation member (B) further has the capability for assuming a stored configuration with the separation member (B) engaged by the lid (A,B) with the lid (A,B) in the closed position. Resiliency of the separation member (B) urges the separation member (B) {acute over (ι)}{umlaut over (ι)}oιη the stored configuration to the deployed configuration when the lid (A,B) is moved from the closed position to the open position.
