<p>A device for opening, or re-closing, and holding lids of containers, each provided with an oblong spout, comprises a removal head of the pneumatic type which has a through housing channel which develops along an axis and in which the spout is at least partly housed, and a holding member, associated to the removal head, to cooperate with the spout. The holding member is actuated pneumatically to define at least a reversible condition of holding the spout inside the housing channel and comprises elastically deformable means which laterally delimit the housing channel. The elastically deformable means are configured to be deformed elastically by means of a fluid under pressure, so as to selectively define a reduction in section of the housing channel suitable to hold the spout.</p> |
