Abstract: A method for printing the cylindrical side surfaces of synthetic resinous corks used for wine bottles which are normally not receptive to printing inks. The method includes the steps of gas flame heating of the corks to slightly soften the surface and deposit unburned carbon particles thereat. The application of a printed image using an offset roller, the drying of the ink in a heated conduit, and the subsequent application of a high viscosity lubricant in dot pattern using an offset printing roller. The application of the lubricant in a pattern covering less than the entire surface permits the cork to release sulphur dioxide gas for oxygen scavenging of any air passing into the bottle, as well as air disposed in the head space within the bottle.

Abstract: A childproof closure for containers is particularly suited for use by arthritic or manually handicapped adults which retains child resistant qualities. This is accomplished by a thumb-engageable projection extending from the upper surface of the end wall of the closure at that portion of the circumferential periphery adjacent the opening index mark.

Abstract: A wide mouth container or jar suitable for storage of viscous jells, such as hair dressings in which the closure includes provision for preventing unauthorized removal by children. To open the closure, it must be rotated to a predetermined location relative to the container to align a small radially extending tab opposite a corresponding gap in a radially extending flange on the outer surface of the container, following which the tab is pushed in a direction away from the flange to free to closure.

Abstract: A safety type cap for medicinal or similar containers capable of effecting a tight seal upon the container mouth by means of a sealing flange extending laterally from an inner surface of the cap rim which is deflected upon contact with a corresponding flange on an area surrounding the mouth of the container. The cap is held in sealed relation relative to the container by engagement of a pair of arcuate projections which engage a sufficient degree of the container periphery so as to resist dislodgement made possible by flexing of the container without alignment of the cap relative to the container for normal usual disengagement.
