Abstract
The invention provides an apparatus for sealing containers which comprises a sealing head 16 for sealing a peripheral edge portion of a lid L to the inner surface of a downwardly tapered body wall B of the container C. The sealing head 16 is provided with a seal holding face 72 fittable to the inner surface of the container body wall B. The seal holding face 72 has an upper region 91 and a lower region 92. Recesses 93 are formed respectively in a plurality of portions of the lower region 92 along the circumference thereof for absorbing the slack produced in the peripheral edge portion of the lid L at the time of sealing. The apparatus obviates faulty seals in containers and gives an improved aesthetic appearance to the sealed portion.
