Abstract: The invention concerns an original-seal closure means made of plastic and for threaded mouths at containers, in particular bottles. The closure means includes a screw cap to which a hood is fastened with axial play. Studs are present at both the hood and the screw cap, which can be engaged and disengaged within the said axial play and which act as drive means. To secure the original seal, the screw cap is provided with tear-off elements which engage by means of claws underneath the retainer lip. When the mouth is sealed, the claws are held in this position by the hood. When the closure is opened the first time, the tear-off elements are perforce torn off. In additional child-proof design, a set of studs is designed in such a manner that they shall always act as drive means during the screwing shut process while they shall act thusly during unscrewing only if in addition to the torque an axial force is exerted toward the mouth.

The drive system comprises a friction wheel and a friction track provided between the slide and the stationary slide guide.

Abstract: Deformity, displacement and expulsion of the ocular tissues during eye surgery of the type in which there is a cut through the ocular wall, is opposed by the method and apparatus of this invention. According to the invention, the external surface of the eye is divided into two areas by defining a line on the external eye wall that forms a closed loop surrounding the sites where incisions through the eye wall are to be made or where cuts through the eye wall have already been made by traumatic injury. Then, according to the invention, air pressure higher than atmospheric is generated, when needed, in a work space outside the eye adjacent to that part of the external eye wall that lies within the closed loop, without compressing the external surfaces of the eye that lie outside the closed loop. The eye is concurrently stabilized against the applied pressure by attachment to a fixation device, usually at points along the line between the pressurized and non-pressurized zones of the external eye wall.
