1. A stopper for a container, comprising:
- a hollow shell forming an outer layer of the stopper and comprising a solid polymer;
an inner layer disposed within the hollow shell, wherein the inner layer is formed from a cold-flowable polymer, the cold-flowable polymer being deformable when an object is inserted therein and sealable when the object is removed; and
a casing having a peripheral wall and a hollow interior, wherein the peripheral wall at least partially encases the inner layer and the outer layer is positioned over at least an exterior surface of the casing.

Abstract
A stopper is generally provided in which a hollow shell includes at least one outer layer and an inner layer positioned within the outer layer. The outer layer is formed from a substantially solid polymer while the inner layer is formed from a cold-flowable polymer. The cold-flowable polymer is deformable when an object is inserted therein and is scalable when the object is removed.
