ABSTRACT OF THE DISCLOSURE: In an apparatus for expanding a sheet carrier and fitting it onto containers which comprises a funnel member possessing a radially contractable leading end, a sleeve member for accommodating the aforementioned funnel member, a radially contracting member interposed between the afore- mentioned funnel member and sleeve member and an axial member disposed within the funnel member and possessing a expanded leading portion, the open end of the funnel member is radially contracted by the forward movement of the contracting member and admitted, in conjunction with the expanded portion of the axial member, into the opening of the sheet carrier and, thereafter, the open end of the funnel member is allowed to resume its original shape. Then, by fitting the peripheral edge of a container into the open end of the funnel member and moving the funnel member backwardly relative to the sleeve member, the opening of the carrier fitted round the outer surface of the funnel member is pushed up the outer surface of the funnel member by the open end of the sleeve member and, as a result, radially expanded in proportion as the outside diameter of the funnel member is increased. Eventually, the opening is caused to ride over the open end of the funnel member and wrap itself round the outer surface below the peripheral edge of the container.
