Abstract
The embodiments of the present disclosure provide a stopper comprising a plug and a pierceable membrane, the plug including a cavity between a pierceable membrane and a lower opening. The pierceable membrane and the cavity can form a tortuous path that reduces interactions between the contents of the container and the ambient environment. The cavity can be bounded by a plastic insert disposed within the plug. The plastic insert can include insert walls, the lower opening, and an insert flange. The pierceable membrane can be bonded to an upper surface of the insert flange.
Claims18
A sealing system for a container, comprising:
- a plug configured to conform to an inner wall of a neck of the container, a first cavity extending through the plug, the first cavity being coaxial with the plug;
- an insert disposed within the first cavity;
- and
- a membrane over the insert, the membrane sealing a top opening of a second cavity formed within the first cavity between the insert and the membrane;
- wherein a top surface of the plug comprises a recessed shelf abutting a top opening of the first cavity;
- and
- wherein the insert comprises an insert flange, a bottom surface of the insert flange contacting a top surface of the recessed shelf, and a top surface of the insert flange is bonded to the membrane.
A stopper comprising:
- a plug configured to conform to an inner wall of a neck of a container, the plug comprising (i) one or more walls forming a cavity having an upper opening and a lower opening and (ii) a recessed shelf abutting the upper opening, where the upper opening is larger than the lower opening,
- a pierceable membrane covering the upper opening of the cavity, where the pierceable membrane comprises a material that is different from one or more materials of the plug;
- and
- a plastic insert within the cavity, the plastic insert comprising an insert flange;
- wherein a bottom surface of the insert flange contacts a top surface of the recessed shelf.
