    Abstract: A sealing cap and container combination primarily intended for use in medical applications. The sealing cap of the preferred embodiment includes a central dome-shaped portion, annular portion, and sealing portion. In use, these portions are initially received in the mouth of the container and assume an initial concave shape with the sealing portion of the cap abutting and sealing against the inner surface of the container mouth. Thereafter, as the pressure within the container increases, the concave dome first moves toward a flattened shape and then inverts to a convex shape. As the pressure further increases, the annular portion of the cap then moves to a flattened position substantially perpendicular to the axis of the cap. During all this controlled movement, the sealing force of the cap progressively increases from an initial force to a maximum sealing force.

  • Patent number: 5240131
    Abstract: A tamper evident closure for a container has a seal member which is in a concave or convex condition to show closure integrity. The seal is visible through an opening in the cover of the container. Filling the container under pressure which is higher or lower than atmospheric produces the distention or contraction of the seal member that evidences that no tampering or leakage has occurred.

  • Patent number: 5119962
    Abstract: This relates to a closure cap having an end panel which is equipped with a central button or panel area so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area has been found and such additional stored energy is obtained by utilizing faceted areas or portions.

  • Patent number: 5033633
    Abstract: This relates to the formation of a vacuum indicating button in a molded plastic closure. The button is formed by cold working which results in the flow of plastic material from a central portion of the end panel towards the center of the central portion and the automatic formation of an upwardly projecting generally curved button. In all forms the button is formed by cold working of the plastic. The button may be formed by coining between two opposed tools, or the button may be formed by cold working only the top side of the central portion of the end panel by such methods as including spinning, mechanical peening and shot peening. In the case of coining, the button may be formed either by a single annular ring of cold worked, oriented, reduced thickness material or by a plurality of such rings.

  • Patent number: 5016769
    Abstract: This relates to a conventional type of closure having a central button which is normally provided with an "up" convex state and which is movable by a vacuum within an associated container to a "down" concave state. The button, as formed, has a zero or tensile stress state with the stress state changing to a compressive stress state when the button is drawn downwardly by a vacuum within the associated container. In accordance with this invention, the button has been reformed so that it is slightly flattened and this reforming has changed the zero or tensile stress state to a compressive stress state thereby providing the button with more stored energy when it is drawn downwardly by a vacuum within an associated container. This additional stored energy provides for a greater flipping action of the button which can be utilized to operate an irreversible tamper indicating system which may be applied to the button.

  • Patent number: 4887730
    Abstract: A closure or cap for containers, bottles and jars having a circumferential groove formed by opposed conical surfaces of substantially equal size in the relaxed condition and upon compression of the closure forming a substantially toroidal circumferential groove. On a container sealed with the closure compressed, expansion of the circumferential groove to the relaxed condition indicates failure of the seal or generation of gases within the container. In an alternate embodiment the circumferential conical surfaces form a V-shaped circumferential protrusion in the relaxed condition and a toroidal protrusion in the compressed condition. In another embodiment the circumferential juncture between the conical surfaces and the closure sidewall is modified to reduce the flexure between the compressed and expanded conditions thereby permitting a wider variety of materials to be used for the closures.

  • Patent number: 4852753
    Abstract: A closure cap is disclosed for sealing containers and particularly for sealing thin-walled vacuum formed containers with threaded rims. The closure cap is a composite closure having a molded plastic ring for engaging the container and for mounting a disc-like metal cover. The metal cover includes a vacuum indicating disc particularly adapted for providing a positive indication for relatively low vacuums and the closure cap is adapted for being sealed onto the container with a combination of press-on and screwing action to provide for high speed vacuum sealing. The vacuum indicating action of the vacuum button is improved by providing a channel in the plastic ring at the edge of the metal cover for stablizing the button operation at the desired low vacuum levels.
