An improved opener for a packaging container arranged to form an opening in one wall to remove the contents includes a tear-open portion surrounded by a weakening line and a pull tab connected to the tear-open portion. To enable use of the pull tab as a reclosure element, it has a stopper-like lower extension which has a complemental outline to that of the tear-open portion and on which a shear edge is disposed. The pull tab is firmly connected to the tear-open portion with a narrow strip of a fusing glue.

Opener for a packaging container

A lid for a packaging container which include a tear-open part which is surrounded by a weakened line. The lid is molded of a composite material, which has an outer carrier layer of plastic, a middle barrier layer of metal foil and an inner heat-sealing layer of a thermoplastic synthetic material. The weakened line is produced as an indentation in the outer carrier layer by being heat-impressed using a heated tool.

Container lid having an opening device

A method and an apparatus are proposed for sterilizing containers before they are filled, with which it is possible to subject heat-sensitive containers to sterilization by a heating medium. While the interior of the containers is subjected to heated vapor, the exterior of the containers is cooled, so that in the wall of the containers the overall temperature of the wall is kept so low that deformation is avoided. To provide such cooling, either a cooling element complemental in shape to the outer contour of the containers, or a coolant-spray device, may be used.

Method for sterilizing containers

A light weight packaging container, similar to a capsule and made by deep-drawing and/or stretching of a multi-layer foil composite, is composed of synthetic material and aluminum. An aluminum layer or foil having a thickness within the range of from one grain to a few grains is provided. At least one layer of synthetic material is fixed to the aluminum layer or foil. The total thickness of the synthetic layer or layers is substantially greater than that of the aluminum layer or foil. In one embodiment, only one layer of synthetic material is provided. In another embodiment, two layers of synthetic material are provided, one being fixed to one major surface of the aluminum layer or foil and the other being fixed to the other major surface of the aluminum layer or foil.

Light weight package container made from multi-layer material

A childproof design for packages for tablets, pills and the like includes a conventional base foil provided with indentations or cups to receive the tablets. A cover foil is provided, as a seal, over the base foil. The package is rendered tamperproof by the inclusion of cavities in the base foil within which the cover foil can be grasped and peeled off but which are concealed and inaccessible until an individual tablet package is severed from the whole pack.
