A reclosable plastic bag (10) having two panels (15) of plastics sheet or film joined to, or integral with, each other, or a combination of both, to define a bag with an opening (13), with separable fastening means (14) of one or more interengagable elongate rib/groove configurations (14a, 14b) are provided to close the opening (13). A slider (100) is positioned in straddling relationship to the fastening means, and includes a support member (111) overlying the opening to the bag and straddling the fastening means, and also carrying a separating finger (112) to engage with and separate the fastening means when the slider is moved to a first end of the fastening means in a bag opened condition, and a pair of legs (113) extending from said support member to force the fastening means into interengaging relationship when the slider is moved to a second end of said fastening means in a bag closed condition. Flanges (119) on the legs extend beneath the fastening means to retain the slider on the bag. The edges (19) of the panels of the bag adjacent the second end of the fastening means are bonded together with a portion thereof between the bonding and said fastening means being crimped to define a torturous path (20a) between the panels into which path the separating finger (112) the slider is received to be gripped by the portions of the panels on either side of the torturous path to thereby retain the slider in the bag closed condition.
L'invention porte sur un sac (10) de plastique refermable comprenant: deux feuilles ou films (15) de plastique reliés ensemble ou formant un tout, ou combinées, de manière à former un sac présentant une ouverture (13) munie de moyens séparables de fixation (14) sous la forme d'un ou plusieurs ensembles nervure/rainure (14a, 14b) allongés interengageables permettant de fermer l'ouverture (13); et un curseur (100) placé à cheval sur les moyens de fixation (14) et comportant: un support (111) surplombant l'ouverture et à cheval sur les moyens de fixation, un doigt (112) s'engageant dans les moyens de fixation pour les séparer alors que le curseur se déplace vers une première extrémité pour ouvrir le sac, deux joues (113) partant du support et forçant les moyens de fixation à s'engager l'un dans l'autre lorsque le curseur se déplace vers la deuxième extrémité pour fermer le sac, et des rebords (119) prolongeant les joues et retenant le curseur sur le sac. Les bords (19) des feuilles formant le sac jouxtant la deuxième extrémité des moyens de fixation sont soudés ensemble et leur partie comprise entre la soudure et lesdits moyens de fixation est déformée de manière à créer entre les feuilles un passage tortueux (20a) dans lequel le doigt de séparation (112) s'engage, et où il est retenu par les parties des feuilles entourant ledit passage, ce qui immobilise le curseur lorsque le sac est en position de fermeture.
