Title
(EN) CHILD-RESISTANT CLOSURE AND CONTAINER APPARATUS
(FR) ENSEMBLE RECIPIENT ET FERMETURE DE PROTECTION A L'EPREUVE DES ENFANTS
Abstract
(EN) A child resistant closure apparatus that is easily opened by the aged and infirm has a container (200) having a push-tab locking device (300) that locks into place in a series of sawtooth projections (150) on an inner surface of a closure (100). The closure (100) is rotatably screwed onto the container (200) whereby the push-tab locking device (300) locks into one sawtooth projection (150). Screwing torque in the direction which would disengage the closure (100) from the container (200) is not permitted unless the push-tab locking device (300) is manipulated so that an end of a flexible arm (310) is removed from the sawtooth projection (150).
(FR) Ce système de fermeture de protection à l'épreuve des enfants pouvant, toutefois, être ouvert par une personne âgée ou infirme, consiste en un récipient (200) pourvu d'un système de verrouillage à patte-poussoir immobilisant une série de saillants en dents de scie (150) sur la face interne d'un couvercle (100). Ce couvercle (100) se visse sur le récipient (200), ce qui amène le dispositif de verrouillage à patte-poussoir (300) à entrer en prise avec l'un des saillants en dent de scie (150). Il est impossible d'exercer un couple de vissage dans un sens susceptible de dégager le couvercle (100) du récipient (220) tant que le dispositif de verrouillage (300) n'a pas été manipulé de manière à désolidariser un bras souple (310) du saillant en dent de scie (150).
