A twist open/twist close edge seal closure is described wherein the closure has a sealing disc supported on the interior portion thereof which vertically rises and lowers depending on the rotation of the closure. The sealing disc has a folding finger which compresses against the sealing rib of the container to provide an adequate seal thereof and allows dispensing of the container contents around the exterior portion of the sealing disc upward through a dispensing channel and through the dispensing spout of the edge seal closure. The closure further comprises an anti-crush rib for seating on a container top wall and preventing crushing of the container neck. The container neck preferably includes a quad-lead thread having a pitch wherein a quarter rotation of the closure will open the container and allowing dispensing of the contents therein.

Edge seal closure

A bottle having a modified neck and intended for use with a child-resistant closure which allows the user to open the bottle without removing the closure completely from the bottle is described. The neck includes at least one locking lug and at least one anti-removal ring. The anti-removal ring is positioned between the lug and the open end of the neck. The neck may further include at least one deformation recess, with the deformation recess being adjacent to and radially offset from the locking lug. The ring and recess are intended to deter the user from bypassing the child-resistant safety features of the bottle and removing the closure completely from the bottle.

Modified bottle neck for use with child resistant caps

A safety closure including a top wall, a side wall depending from the top wall, and a locking tab projecting outwardly from the side wall, the locking tab having a reinforced end integrally connected to the side wall and a free end connected to the side wall by a biasing strap, wherein the reinforced end of the locking tab inhibits movement of the free end of the locking tab in at least an upward direction.
