The invention relates to a packaging, preferably for foodstuffs, said packaging comprising a container and a lid, both of which is made of a material which is suitable for injection moulding, said lid being sealable relative to the container; and wherein the lid comprises an elevated portion for abutment on the internal, upper edge of the container, wherein at least a portion of the lid () is made with a sealing zone () for joining with the container (), said sealing zone () being added with an active material which, by influence during joining, changes the material in the sealing zone () to the effect that the sealing becomes weaker than the surrounding material, whereby the scaling is, upon opening, broken in the joint and not in the surrounding material. The invention also relates to a method of sealing the above packaging, wherein a material is added which, during the sealing procedure, changes the material in the joint to the effect that the seal becomes weaker than the surrounding material, whereby, when opened, the seal is broken in the joint and not in the surrounding material.

Packaging with lid sealable to container and a method of sealing the packaging

A lid that can be sealed to a container to provide packaging includes an edge with a pull tab which facilitates removal of the lid from the container. The lid and pull tab are injection molded integrally, and the pull tab has the form of a flexible grid-like flap that is bendable to a substantially upright position. The pull tab is formed by a number of spaced, parallel and interconnected bars that extend in a direction substantially at right angles to the direction of pulling of the pull tab.
