A molded plastic container, such as a five gallon pail, that includes a lid and main body that are selectively attachable to each other without a resilient gasket. The main body of the plastic container includes a flexible sealing finger formed along the top rim of the main body. The flexible sealing finger is received within a sealing chamber formed as part of the rim. The sealing chamber is defined by a gland seal such that when the lid is attached to the main body, both the flexible finger and the gland seal can deflect to create multiple sealing points between the flexible sealing finger and the sealing chamber. A latch ring is formed on the outer surface of the main body and engages a locking tab formed on the lid to hold the flexible finger in the sealing chamber.

Contenant en plastique moulé, par exemple un seau de cinq gallons, qui comprend un couvercle et un corps principal pouvant être fixés l'un à l'autre sans joint élastique. Le corps principal du contenant de plastique comprend une bande d'étanchéité souple formée par le bord supérieur du corps principal. La bande d'étanchéité souple s'insère dans une chambre d'étanchéité s'intégrant au rebord. Un joint d'étanchéité définit la chambre d'étanchéité, de manière à ce que la bande flexible et le joint d'étanchéité puissent dévier et créer plusieurs points d'étanchéité entre la bande d'étanchéité souple et la chambre d'étanchéité, lorsque le couvercle est fixé au corps principal. Un anneau de maintien se trouvant sur la surface externe du corps principal retient une languette de verrouillage formée sur le couvercle afin de maintenir la bande flexible dans la chambre d'étanchéité.
