Abstract: A container and closure assembly which is resistant to opening by a child, and which includes a container having a cylindrical neck portion having an annular safety ring key or key way therearound. A safety ring is rotatably mounted on the neck portion and is retained against axial movement thereon by the key or key way. The safety ring defines an access tab relief, and also an access tab safety recess adjacent the access tab relief. A closure cap which is dimensioned to fit over and close the opening at the upper end of the neck portion is hinged to the neck portion for pivotation between an open and closed position. The closure cap carries an access tab at a location spaced around the cap from the hinge by which the cap is connected to the neck portion.

Abstract: Cooperating top and bottom die assemblies for use in a press to fold the edges of a non-rigid workpiece. The top die comprises a horizontal support plate having a radiused folding plate affixed to its underside. A spring biased stripper in association with the support plate is shiftable vertically relative thereto between a retracted position and a normal extended position below the radiused folding plate. The top die assembly support plate has a plurality of upstanding support posts on its upper surface together with means to affix the top die assembly to the upper platen of the press with the free ends of the upstanding support posts in abutment thereagainst. The bottom die assembly comprises a horizontal base plate adapted to rest on the bottom platen of the press. The base plate has a first set of downwardly depending hollow posts mounted on its underside to either side of the press bottom platen.

Abstract: An apparatus for folding and sealing the edges of a non-rigid work piece and a method of performing folding and sealing operations therewith. The apparatus comprises a press with a main cylinder, at least one auxiliary cylinder and upper and lower die assemblies for the press. The upper die assembly comprises a folding cavity plate operatively connected to the main cylinder and having a folding cavity with an electrode surrounding a part at least of the cavity. A stripper in association with the upper die assembly is independently shiftable by the at least one auxiliary cylinder between a retracted position above the folding cavity and an extended position therebelow. The bottom die assembly comprises a plate having a female cavity therein of a size and shape equivalent to that of the folded work piece and a male plug receivable within the female cavity with close tolerance.
