A method of applying a label to a container which includes an intermediate portion of the sidewall thereof which has an annular curved surface wherein the vertical height of the portion having a curved surface is a minor portion of the entire height of the container. A narrow rectangular label of shrinkable material is first provided with one or more longitudinally extending strips of adhesive extending intermediate the longitudinal edges of the label at the area of the label which is to contact the portion of greatest diameter on the curved portion of the container. The strip of adhesive material is shorter than the length of the label so that the adhesive material does not contact the overlapping edges of the label. An adhesive is applied to the trailing edge of the label only and the label is wrapped about the compound curved portion with the adhesive strip engaging the curved portion of the container at the area of greatest diameter. The edges of the label are overlapped and bonded and the overlapped label is then shrunk into position by moving the container and label through an oven. The curved portion of the container may have a compound curvature.

1. A package that comprises: a container that includes a sidewall, an intermediate portion of the sidewall having a continuous curvature in an axial direction wherein the axial height of the curved portion is a portion of the entire height of the sidewall of the container, said curved portion having an upper end and a lower end, said curved portion having a portion of greatest diameter transverse to the axial height of the curved portion of said container, said portion of greatest diameter being spaced from the upper end and the lower end of said curved portion, said curved portion of said container having a compound continuous curvature comprising portions having differing radii such that the curved portion of the container has a greatest diameter spaced from a transverse centerline of the curved portion,a rectangular label of shrinkable material having a leading edge, a trailing edge and spaced upper and lower longitudinal edges, said rectangular label having a width between said longitudinal edges, a strip of bonding material extending longitudinally of said strip along a line intermediate the upper and lower longitudinal edges of said label spaced from a longitudinal centerline of the label substantially the same distance as the portion of greatest diameter of the container is spaced from the centerline of the curved portion of the container at the area of the label which is to contact the portion of greatest diameter on the curved portion of the container, and such that said strip of bonding material is spaced from the leading and trailing edges of the label such that it does not contact the leading and trailing edges of the labels, the label being wrapped about the curved portion of the container with the bonding material engaging the container at the portion of greatest diameter of the curved portion, the leading and trailing edges of the label being overlapped and bonded to each other, the overlapped label being heat-shrunk into position on the curved portion of the container.
