Abstract: A method and apparatus for formation of a preformed bonded pull tab over a reseal liner is disclosed. The pull tab seal layer of material is bonded together with a reseal liner layer of material for insertion into a closure. The pull tab on the pull tab liner seal is formed prior to combination of the two layers and is folded backwards between the two layers of material. Thus, after combining the two layers, punching out the closure liner and insertion into the closure, the reseal liner is separated from the pull tab seal and the pull tab seal is adhered to the rim of the container. Only one punch press step is required for forming the closure and container seals and insertion of the members into the closure. By forming the pull tab prior to combining the two layers, an assembly of the pull tab and reseal liner is made more efficient and less time consuming.

Abstract: A container closure has a generally planar base (2) with an aperture (5) therein which is adapted to be mounted on a wall of a container to surround an aperture therein with the two apertures in register. A flap (3) is connected to the base for movement between a closed position in which the flap overlies the base and an open position in which the base is exposed. A plug (7) formed on the flap enters into and closes the base aperture when the flap is in the closed position and a removable film strip (4) is detachably mounted on the outer surface of the base to cover and close the base aperture. The film is so constructed that it can extend around the plug when the plug is located in the base aperture.

Abstract: A child resistant cap including relatively thin threads which, when the cap is in a relaxed condition, are spaced from the bottle neck, said spacing permitting the cap to be squeezed inward at points on opposite sides of the cap so that the cap responds to the squeezing by expanding outward at points ninety degrees from the squeezing points so that stops on the cap at the cap expanding location will miss the stops normally engaged when in a relaxed condition, thereby permitting the cap to be removed from the bottle. The cap may also include a guide ring in the cap interior to guide the cap over the bottle neck to help ensure that the cap is centered on the bottle opening. The cap may include pressure pads on the cap skirt outside near the cap bottom showing the user where to press and stiffening the portion of the cap where pressure is to be applied. And, the cap may include a tamper indicating ring which will separate from the cap the first time the cap is removed from the bottle.

Abstract: A safety closure providing a top wall, an annular outer wall depending downwardly from an outer periphery of the top wall, an annular inner wall depending downwardly from an underside surface of the top wall, and, at least one locking lug integrally molded with the outer wall, whereby downward displacement of the top wall causes outward displacement of the at least one locking lug.

Abstract: A tamper indicating bridged fitment is provided having an annular flange and an upwardly extending cylindrical side wall. Said fitment has a tamper indicating feature which is comprised of a bridge connected to the top edge of said upwardly extending cylindrical side wall by frangible webs. The tamper indicating bridge additionally has a slot formed longitudinally therethrough, said slot receiving a tab extending upward from a plug. The plug is a separate element which is comprised of a tab and a top wall and additionally has a downwardly extending cylindrical seal wall which acts to seal the fitment. Once the tab is inserted through the slot in the tamper indicating bridge, the fitment may only be opened by breaking the frangible tamper indicating webs connecting the bridge to the fitment side wall. Once the webs are broken, the plug may be removed by the tab and the bridge is thereby disconnected from the fitment.
