  • Patent number: 5654022
    Abstract: A capsule for placement over bottle tops, particularly tops of bottles of wine having a flanged bottle top which defines a pouring surface surrounding an opening of the bottle closed with a cork and an exterior undercut. The capsule is constructed of a heat shrinkable material, covers the pouring surface, engages the undercut, and includes a weakened break line positioned so that the break line overlies the periphery of the bottle top flange. The capsule is transparent and includes an opaque band at its free, lower end which is dimensioned and positioned to overlie and thereby hide from view a lower end of the cork and a fill line formed by the wine in the bottle. The base of the capsule includes a hole which is about the same size as or slightly larger than the bottle opening. An opaque, preferably metallic, disk is affixed e.g.

  • Patent number: 5647494
    Abstract: A tear-off safety closure is described in particular for ensuring authenticity and for additional sealing of a bottle-shaped container containing especially pharmaceuticals which is already closed by a disk-shaped or plug-shaped sealing element. The cap surface and the closed flange-shaped jacket of the closure enclose the sealing element and the rim of the container neck which has an outwardly projecting ridge. The closure has a tear-out part which can be detached to expose the surface of the sealing element, e.g., for piercing with a hypodermic needle. The jacket has retaining devices which are arranged on its inner surface at a distance from its lower edge and which engage under the lower edge of the ridge. The closure is produced from plastic in its entirety and so as to form one piece, in particular from thermoplastically deformable plastic such as polypropylene or polyamide.

  • Patent number: 5597016
    Abstract: An improved mechanical system selectively locks the tester valve of an annulus pressure responsive tester valve in position for an indeterminate number of well annulus pressure cycles. The tester valve also features a multi-range metering cartridge which is operable to meter fluid over a wide range of differential pressures. The metering cartridge provides an adjustable resistance flow path which permits fluid flow across the cartridge. The resistance of the flow path is adjustable by selectively diverting the fluid through a series of fluid flow resistors. Resistance may be increased either by adding a number of flow resistors serially or by adding a single flow resistor which itself provides a greater fluid flow resistance.

  • Patent number: 5509552
    Abstract: A capsule having a cap portion may be torn together with a pulling tab for tearing. The capsule comprises the cap portion and a skirt portion. Two weakening lines for tearing the cap portion are provided between the cap portion and the skirt portion. One of the weakening lines on the cap portion side is inclined to a top of the cap portion with a certain inclination as it approaches near the tear-terminating end. When pulling the pulling tab outwardly, the cap portion is torn along the weakening lines. Then, as it approaches near the tear-terminating end, the cap portion is torn upward toward the top, thereby opening the cap portion. Thus, the cap portion is removed from a cap of a bottle together with the pulling tab in one unit.

The container comprises: a bottle having a side wall portion and an open mouth portion; a cap connected to the bottle mouth portion; a frangible label connected to the bottle side wall portion; a wrapper having an upper portion that overlies the cap and a lower portion that overlies the bottle and at least a portion of the label so that the cap is sealably fixed to the bottle; and means for securing the wrapper lower portion with the frangible label. The wrapper upper portion is removable from the container and the cap so that the cap can be separated from the container. Removal of the wrapper lower portion ruptures the frangible label; the label rupture serves as a visible indicia of the removal of the wrapper bottom portion from the bottle, and thus alerts the consumer to possible tampering.

  • Patent number: 5065883
    Abstract: A tamper evident, unitary, plastic overcap adapted to be placed over a container neck flange, which neck flange has, adjacent its outboard end, a radially outwardly protruding annular ridge. The overcap comprises a relatively thin, flat, round, end wall having extending axially inboard therefrom an a cylindrical skirt with a plurality of circumferentally spaced, integral projections extending radially inward from an inboard portion of said skirt and adapted to underlie a container neck flange ridge, so that said overcap cannot be removed from a container neck flange without at least partial destruction of said overcap.

  • Patent number: 5054633
    Abstract: A tamper evident safety closure for containers composed of an assembly of an inner cap and an outer cap, the inner cap provided with threading for screwing onto the mouth of a container. The outer cap can be depressed over the inner cap against a resilient force and the caps can be unscrewed from a container only after depressing the outer cap. A central upstanding part on the inner cap cooperates with a bridging wall portion, bridging a central opening in the top wall of the outer cap and connected thereto by a rupturable connection. There is an asymmetry in these parts so that the bridging wall portion does not rupture instantaneously all around its periphery but either remains connected to the outer cap with showing plastic deformation or ruptures gradually around its periphery or both.

  • Patent number: 5048706
    Abstract: A cap is composed of a cylindrical skirt provided with a central opening, and ensures the locking of a plug in the opening of a neck of a container. A tear-off lid is sealed onto this cap and, by means of a projecting part on a gripping ring of the cap, is connected by a strip to a portion of the upper end of the skirt delimited circumferentially by tear-off lines parallel to the generatrices of the skirt, extending over the entire height of the latter and associated with partial cuts. The skirt tears off when the lid is torn off by means of the ring. The cap is particularly useful for sealing of containers for sterile non-injectable pharmaceutical products.

  • Patent number: 5005718
    Abstract: A tamper-evident child resistant closure device is provided. The tamper-evident child resistant closure device includes an inner cap having a first set of teeth, an outer cap which fits movably over the inner cap and has a second set of teeth adapted to operatively engage the first set of teeth to facilitate removal of the closure device and inactivatable engagement prevention means for preventing engagement of the first and second sets of teeth. The engagement prevention means functions independently of the configuration of a container on which the closure is used and prevents the removal of the closure device from the container. Once the engagement prevention means are inactivated, the first set of teeth on the inner cap can engage the second set of teeth on the outer cap when the outer cap is displaced axially downwardly with respect to the inner cap. The closure device can be taken off a botttle when the teeth are engaged.

    Abstract: A blow-molded container is provided with an insert occluding its top opening. A closure structure at least partially encapsulates the insert article and includes a frangible web formed against the insert article. The container can be blow-molded in main mold halves and the closure structure, including the frangible web, can be formed by additional mold halves while the insert article is held in the container opening by an arm that is subsequently retracted or while the insert article is supported on a parison portion that defines the container body. In the latter instance a complete overcap for the insert article can be provided.
