Title
(EN) VACUUM ACTUATED MECHANICAL LATCH
(FR) PENE MECANIQUE ACTIONNE PAR LE VIDE
Abstract
(EN)
A vacuum actuated mechanical latch (34) which is attachable to a hermetically sealable container (10) is described. The latch (34) is attached, formed, or otherwise integral with the door (12) of the container (10). The latch (34) is easily engaged and disengaged by processing equipment (14). Also, the latch (34) is designed to minimize the amount of abraded particulate and further isolates any particulate generated. Further, when the door (12) is latched to the container (10), the latch (34) is not easily overcome by jarring or bumping. The lead-in surface (88) of the latch (34) is angled to minimize friction when the latch (34) is forced into a first locking position.
(FR)
Pêne mécanique (34) actionné par le vide pouvant se fixer à un réceptacle (10) se fermant hermétiquement. Le pêne (34) est fixé, formé ou intégré dans la porte (12) du réceptacle. Le pêne s'engage et se désengage facilement par un outillage de fabrication (14). Il (34) est également conçu pour réduire la quantité de matières particulaires abrasives et assure en outre l'isolation de n'importe quelle matière particulaire générée. De plus, lorsque la porte (12) est enclenchée sur le réceptacle (10), le pêne (34) résiste aux secousses ou aux coups. La surface d'attaque (88) du pêne (34) est à l'oblique de façon à réduire la friction lorsque celui-ci (34) est poussé dans une première position de verrouillage.
