Abstract: A container safety cap having an internal structure and an external structure for sealing an end of a container, vessel or conduit, for example. A safety seal is placed across a surface formed from the internal and external structures. Movement of either structure will cause the seal to break and indicate a violation of the integrity of the seal. The external structure will, in a closed position, force hooks of the internal structure into a groove of the container being sealed. Movement of the external structure into an open position will allow removal of the internal structure, together with the external structure, from the container being sealed. The container can be resealed by having the internal structure of the cap fitted onto the container, followed by displacement of the external structure to lock the hooks of the internal structure in place.

The teeth inside the cap each have a trailing face extending radially at an upper end thereof and lying in a plane sloping toward the thread loosening direction of the cap at an angle greater than or equal to 1.degree. relative to the central axis of the cap for creating a camming action between the closure teeth and the neck finish teeth tending to cam the closure down on the container in response to closure rotation in the loosening direction.

Abstract: A composite closure for a container has an outer ring with a half-toroidal lip which overhangs a bead around the periphery of an insert cover disk. As the closure is tightened on the container the lip bears downwardly on the bead of the disk and urges the disk against the container rim. Reaction force uncoils the lip like a watch spring, and a visible gap develops between the inner edge of the lip and the disk. This gap provides a visible on-line indicator that the lip is exerting sealing force on the disk. In a second aspect of the invention, a tamper-evidencing band on the closure has ratchets which engage angularly spaced groups of ratchets on the container. Unequal torque thereby acts on bridges which connect the tamper evidencing band to the closure, causing the bridges to break sequentially rather than simultaneously. As a result the bridges can be made stronger and premature breaking is reduced.

Abstract: A vacuum-sealed shipping/storage system based on rigid cylinders of plastic or metal, of various diameters, permanently sealed at one end, with the opposite end having removable, double-sealed vacuum lids. In the case of three inch PVC pipe, the first, or primary lid is a common wide-mouth mason jar lid. Larger cylinders use a similar device. Over each primary lid, a single cap of molded or machined plastic or metal is threaded to a permanently affixed threaded collar, such threaded collar being fastened to the outer surface of the cylinder. Between this secondary cap and collar is found an O-ring, of common design, for the purpose of maintaining a secondary vacuum seal should the primary seal become loosened by shifting contents. Removal of both primary lid and secondary cap exposes the entire inner diameter of the cylinder for insertion or removal of materials. For storage-only applications, where little or no movement of the cylinder is anticipated, the primary lid alone will maintain course vacuum.

The closure cap involved is of a small diameter and is specifically intended for use in conjunction with neck finishes having diameters ranging from 27 mm to 43 mm. The end panel of the closure cap is of a specific configuration so that a small diameter central portion in the form of a button will evert under the existing vacuum conditions so as to present a substantially plain end panel when the vacuum condition exists within the container and which will show a popped up button when the vacuum has been relieved. The button will be indicative of product condition or possible tampering.

Abstract: The screwcap comprises an inner cap and an outer cap. The outer cap is threaded on a container neck. The screwing action presses the inner cap and its sealing layer in an axial direction against the opening edge. An outer edge portion of the inner cap projects radially over the neck and is at a first distance over a projection on the inside of the outer cap collar. The projection only contacts the outer edge portion of the inner cap when the outer cap is unthreaded. Continued unthreading movement initially only raises the inner cap from the opening edge at a locally defined peripheral point through engagement of the projection on the lower edge of the inner cap outer edge portion, prior to complete raising of the inner cap, to eliminate a vacuum in the container. This reduces the force necessary for opening the screwcap.
