Abstract: A cap adapted to cooperate with a container to seal and unseal the container. The cap comprises a circle-shaped knife carried by an inner surface of the cap and a lid adhesively secured to a portion of the inner surface of the cap. The container is sealed by positioning the cap over an opening of the container, which opening is defined by a container edge, and then securing the lid of the cap to the container edge by induction or conduction. The container is unsealed by exerting pressure on the cap whereby the knife cuts through the lid thereby cutting a circular portion out of the lid and unsealing the container. The circular portion cut out the lid remains adhesively secured to the cap.

Abstract: A threaded safety dispensing closure and container package in which the initial threading on of the closure to the product filled container affixes the closure to the container so that it cannot be removed, requiring dispensing through the dispensing orifice in the closure top and inhibiting refilling of the container. The container neck terminates in an annular end wall having a plurality of circumferentially spaced ratchet teeth which coact with the top of the closure cap allowing threading on but locking the cap to the container against unthreading removal. Tamper indication can be provided by an integrally molded insert across the dispensing orifice which is removed by a pull tab.

Abstract: A means of packaging drugs and the like is described comprising a container, having two compartments, one of which is to leave evidence that the container has been previously opened by attaching a plunger to link up with the lower compartment by way of a tip being inserted into the lower compartment and when the cap is removed, said tip will be separated for the plunger releasing a dye along with the tip to remain in said lower compartment, making it necessary to destroy the lower compartment to remove said tip or dye that said drugs and the like can be stored in the upper compartment, making a sure and visible way for packaging, making it known to the consumer should the container have been previously opened.

Abstract: A threaded thermoplastic closure suitable for fitment to a threaded container neck is disclosed. The closure is provided with one or more vent grooves cut through the primary threads in the inner wall of the closure skirt. The ends of each thread segment are rounded and a smaller reinforcing secondary thread within the groove extends across the groove connecting the thread segments. The lower edge portion of the secondary thread is aligned with the lower edge portion of the adjacent segments of the primary thread to maximize the venting space over the secondary thread.

Abstract: A tamper detector cap which is characterized by an internally-threaded inner cap adapted to thread on the neck of a bottle, jar or other container and provided with a flexible diaphragm and spaced wall grooves located in the outer circumference thereof. An outer cap fitted with a transport window and internal, spaced retainer thread segments for threadibly engaging the wall grooves in the inner cap, is also provided. When the inner cap is threadibly attached to the neck of the container and a vacuum is created in the container, the diaphragm is depressed inwardly and the outer cap is threadibly secured to the inner cap by means of the retainer thread segments and cooperating wall grooves, such that the outer cap is sealed on the inner cap. Application of a counterclockwise torque to the outer cap first loosens the outer cap on the inner cap and then loosens the inner cap and breaks the seal between the inner cap and the threaded neck of the container, causing the diaphragm to assume a neutral position.
