ABSTRACT:
A tamper-resistant closure for containers such as bottles of varying sizes for various products wherein the closure has a continuous thread pattern engageable on a matching continuous thread pattern on the container or alternately a snap-on fastening configuration, provides a depending tab having a frangible area transversally thereof formed integrally with the closure and extending alongside a portion of the container. An area of the depending tab is secured to the container by fusing or melting the materials so as to bond the same together preferably by the action of a laser using the natural oscillations of atoms or molecules between energy levels for generating coherent electromagnetic radiation in the ultraviolet, visible or infrared regions of the spectrum of sufficient intensity and duration to achieve the desired bonding of the closure and the container when the same are formed of molded thermoplastic material.
