Peel-peel-push childproof packaging structure

A multilayer covering for a container that has a surface surrounding an opening, comprising:

• a first film containing a plurality of perforations in a first pattern;
• a first adhesive layer, applied to a first surface of the first film;
• a second film containing a plurality of perforations in a second pattern and having a first surface adhered to the first adhesive layer;
• a second adhesive layer, applied to a second surface of the second film;
• an imperforate third film, having a first surface adhered to the second adhesive layer;
• and
• a third adhesive layer, applied to a second surface of the third film and having an exposed surface for adhering thereat to the surface surrounding the opening to cover the opening.

A method of retaining an item in a container in a childproof manner, comprising the steps of:

• providing a container having a flange portion surrounding a recess for containing an item of medication;
• heat sealing to the flange portion a frangible metal foil;
• peelably adhering to the metal foil a first childproof film of plastic material provided with a plurality of perforations in a first pattern;
• and
• peelably adhering to the first childproof film a second childproof film of plastic material provided with a plurality of apertures in a second pattern,
• whereby a young child attempting to bite into the multilayer covering will be frustrated by its physical resistance to biting, whereas older children and adults are enabled to remove the childproof films sequentially at physical weaknesses generated by the perforations and apertures.
