<p>A self-piercing closure for a container includes a laminar closing member, a closure body, and a piercing member for piercing a closing member. After piercing of the closing member, a self-closing valve of the closure dispenses flowable media from the container. In some examples, the piercing member is formed separately from the closure body, and is attachable to the closure body. The closure body may include a deformable region, and deformation of the deformable region may allow the closure body to move from a first position to a second position. Movement of the closure body from the first position to the second position may activate the piercing means.</p> |
