Abstract
An apparatus for closing and sealing filled containers with a lid includes instrumentalities for positioning an individual lid beneath a sealing die which has an underside. The lid is temporarily held and finally joined to a container under the influence of heat and pressure. Suction is used to hold the lid against the underside of the die while it is being joined to the container. A plurality of protuberances are disposed at the underside of the sealing die. Each of the protuberances has an oblique surface. Each oblique surface has a point lying nearest a sealing surface defining an area of the underside, the area thus defined being substantially equal to that of the lid. Each lid can be consequently positioned correctly on a container and becomes fused therewith.
