Abstract: The method applies to a receptacle-closing carousel that includes a rotary platform fitted with receptacle holding members and associated with a receptacle insertion member and with a receptacle extraction member. The method consists in cantilevering out a length of heat-sealable strip in the receptacle insertion direction over a sector of the platform that extends between the receptacle extraction member and the receptacle insertion member, relative to the direction of rotation of the platform.
Abstract: The closure device includes a roll of heat-fusible strip material, an end-of-strip support member, a receptacle placing member for placing successive receptacles at a receptacle closure location facing the end-of-strip support member, a weld head disposed above a placed receptacle, a grasping member disposed facing the end-of-strip support member, and a drive member disposed relative to the receptacle closure location on a side opposite to the end-of-strip support member.
Abstract: The pump comprises a cylinder delimiting a pumping chamber in which a piston is mounted to slide between an admission orifice and a delivery orifice, the piston including a pumping orifice which is associated with a closure member mounted to pivot about an axis adjacent to the pumping orifice and including a closure face that is substantially plane and that faces the piston.
