Abstract
This piercing device for lids constituted of a supple and tearable material includes a substantially plane rigid tab on which a pivoting axis is provided, which axis divides the tab into a piercing arm and a handling arm and is fixed on the lid. In order to produce this axis, there is provided a supple tab having about the same extension as the rigid tab, the supple tab being secured by one face to the rigid tab and by the other face to the lid, at least on the side of the handling arm of the rigid tab. This device is particularly designed to be produced in association with an installation for thermo-shaping, filling and sealing thermoplastic containers.
