Abstract: A container system and method for indicating the proper orientation of the closure of a container. The system comprises a container and rotatable closure, and a label applied in an overlapping relation to the closure and container. The label has an area which can be separated, and alignment indicators on the two segments of the label which are unaligned. In use, after the label has been applied, the closure is removed by unscrewing, breaking the label. Thereafter, when the closure is reapplied, the closure is overtightened to align the previously unaligned alignment indicators of the label to insure a leak-free containeer system after the closure has been reapplied.

Abstract: This relates to a mechanically actuated closure cap which is provided with a tamper indicating feature. The closure cap includes an end panel having a centrally located button that is normally in a button down position, but when the closure cap is applied to a container, it is mechanically actuated to a button up position. A translucent panel is fixedly applied to the closure cap in overlying relation to the end panel and there is positioned between the button and the translucent panel several possibilities of devices for indicating that the closure cap has been applied to a container and either is in its original position relative to the container or has been removed therefrom.

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.

Abstract: This relates to a tamper indicating closure which includes a closure cap having a button which is movable between an elevated position and a downwardly recessed position in accordance with the state of closure of an associated container. In particular, the button is provided with a tamper indicating arrangement which will include a first layer directly attached to the button and an overlying second layer which is connected to the button generally at the periphery thereof. The first layer is in the form of a photoactive layer and the second layer is in the form of a friable filter material. Normally the second layer protects the first layer, but when the button changes its shape, the friable filter layer will crack and expose the underlying photoactive layer to cause a change in the photoactive layer. This change could be in the form of the disappearance of a message, including a UPC code or the developing of a previously formed message on the photoactive layer so as to make that message appear.

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.

Abstract: An originality guarantee for closures of containers, particularly bottles. It has a label (12) which, after it has been removed or damaged, indicates that the closure has been opened. The closure portions (4,6) which are to be moved apart when it is opened are provided with flat recesses for receiving the label (12). The recesses merge from one closure portion into the other or others and together have the external shape and size of the label. Such a label indicates that the closure has been opened when it is torn or cut through. The invention also prevents the possibility of the label being removed and glued on again. This purpose can be served by the said recess which makes it impossible for a user to engage beneath the label with a finger nail or a tool and to lift it away. Instead of a recess a horseshoe-shaped wall (22) can be provided which surrounds at least a portion of the label. It may be broken away so that the user has access to the label.

Abstract: An improved tamper indicating seal is disclosed, characterized by the generation of a unique signature pattern which, if altered, is indicative of tampering. The seal includes a layer of transparent material which is applied to at least a portion of a secure object or container. A plurality of particles of refective material are randomly arranged within the layer in a unique orientation. When the seal is exposed to light, the particles reflect a portion of the light to produce a unique reflective pattern which corresponds with the orientation of the particles. Alteration of the particle orientation as a result of tampering alters the reflective pattern. Thus when the reflected pattern of a seal does not correspond with its original signature pattern, tampering is indicated.

Abstract: A seal for container locks and the like comprises two units (1,2,3;8,14,15) which are snapped into each other. The snap action is carried out by means of a plug (14) forming part of one of the units (8,14,15) and which normally closes a cavity (13) containing an indicating means (21). When the parts are separated the plug is drawn out from this position and allows the indicating means to leave said cavity. In one embodiment the plug (14) is hollow and is closed by means of a steel pin (15) which when inserted has put the indicating means under pressure and the plug has blocking vanes (18). In another embodiment the plug is not hollow but has a weak lower portion and supports a resilient blocking ring. A steel pin floats in the cavity and can break the weak wall when an attempt to brake the seal is made.
