Abstract: A plastic tamper-indicating closure (1) possesses a closure cap (2) on which, by means of weakened web portions (5), a tamper-indicating band (6) is fixed. The tamper-indicating band (6) is provided with a number of blocking elements (8). The blocking elements (8) are connected with the tamper-indicating band via integral hinges (7). During screwing onto the container neck, the blocking elements (8) can be pivoted upwards and radially outwards into a first closed position (I). As opposed to this, during opening of the tamper-indicating closure the blocking elements are pivoted downwards and radially inwards into a second opening position (II). With that, the effective internal diameter will be reduced, by which means the blocking element will be held in engagement with the corresponding locking surface on a container neck.

The base and cover are permanently secured to one another in a second position such that the base and cover may be pivoted with respect to one another. The respective movements of the base and cover in the first and second position enables the case to be displayed in a fully open condition allowing the consumer to view the product within the case.

Abstract: A vent filter assembly may be disposed in a wall of a sealed waste container containing radioactive waste or the like and utilized for venting gases. The vent filter includes a housing coupled to the container. The housing includes a first opening communicating with an interior of the container and a second opening communicating with an exterior of the container. The housing defines a gas flow path between the first and second openings. A filter is coupled to the housing and disposed across the gas flow path such that gas flowing between the openings flows through the filter. The filter includes a porous metal hydrophobic filter medium. The components of the assembly may be fabricated from materials that are durable and resistant to deterioration due to elements stored within the container, as well as environmental elements. Further, the components may be fabricated from the same or similar materials or materials which are compatible with one another.

Abstract: A device for covering the opening formed in a container after the original sealing pull-tab is removed by a user. The device comprises a wire member having a ring like portion fixedly positioned below the top rim of the container. A second portion of the wire member extends horizontally and then angularly downwardly toward the center area of the container top surface. A hinge, formed on the rear portion of a cover member having a surface contact area sufficiently large to cover the opening, is positioned at the rear of the second portion of the wire member. The front portion of the cover member has a channel portion which is adapted to engage the rim thus securing the cover member in position over the opening.

Abstract: A device for sealing the rim space between a floating cover, movably disposed within a storage tank, and the inner wall of the storage tank. The device includes a peripheral sealing ring formed of a plurality of overlapped shoe segments, each segment having a first and second opposed edge to overlap with adjacent segments. Countersunk apertures are provided in each shoe segment, one aperture near the first edge. A fastener extends through each aperture so that a head of the fastener will reside within a recess formed by the countersunk aperture. At least one movable rod extends past the first edge. A clip for each fastener has a space for slidably receiving the rod, each second side free to slidably overlap the first side and the fastener.

Abstract: A generally cylindrical relative rotatable lock structure comprises three relatively rotatable coaxial members. The first and second members have generally opposed surfaces carrying connecting means which interengage to prevent relative axial movement between those members except in predetermined relatively rotatable positions. The third member is supported by one of the first or second members to prevent axial movement relative to the supporting member, but to permit rotatable movement. Friction between the third and non-supporting member causes the third member to rotate with the non-supporting member. The third member has connecting means cooperable with the connecting means on the member which does not support the third member to prevent relative axial movement between the third and non-supporting members except in predetermined relative position.

Abstract: A fitment to be attached to an apertured wall of a container or the like is initially formed (as by plastic molding) with a thin cylindrical plastic molding) with a thin cylindrical wall dimensioned to fit inside the aperture in the container. A flange is formed on the exterior of the cylindrical wall to fit against the exterior of the container wall, surrounding the aperture therein. Preferably the flange slants downward-outward. A curling tool is forced against the end of cylindrical wall, curling it outward-upward to fit tightly against the interior of the container wall opposite the flange, thereby crimping the fitment to the container. Curling of the cylindrical wall may be performed either before or after the fitment is installed on the carton. The fitment is formed to be closed by a cap and preferably to engage the cap in a tamper-evident manner. In a preferred form of the invention the cap and fitment are initially molded as a unitary member.

Abstract: A tamper-evident thermoplastic fitment having a spout and a closure for said spout are welded to a polymer-coated paperboard container or to a flexible plastic container. The fitment and closure are initially molded simultaneously but with a substantial space between the two parts interconnected by an elongated runner which conducts molten plastic from the closure to the fitment. Upon retraction of the core of the mold, the closure is pulled into the spout until shoulders on the parts engage, whereupon the closure is stripped from the mold core. The runner comprises a tear tab which slides through an apertured space on the closure. When the parts engage tangs on the tear tab engage the space, making the assembly tamper-evident. The fitment has a flange which may be welded or otherwise secured to the container. The tab may be pulled by the consumer to open the container. The closure may be unscrewed from the spout or otherwise disengaged.

Abstract: A fitment for a container, such as a carton, has an attachment flange adapted to be sealed to the carton around a pour hole therein. The fitment has a cylindrical spout formed with vertically spaced seal bead and locking bead. The closure has a top disk with a depending skirt dimensioned to slidably fit within the spout. The exterior of the skirt has an external locking bead at its lower end positioned to lock under the fitment locking bead to hold the closure in place and a seal surface to be engaged by the fitment seal bead. Initially the fitment and spout are molded as a unit, the locking bead of the closure and the top edge of the fitment spout being joined by a circular frangible link. The combination is tamper-evident since access to the interior of the carton cannot be obtained without breaking the link. As an alternative, the cap may be separated from the spout and slid inside the spout. Separate cooperable means on the cap disk and fitment flange make this alternative tamper-evident.

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 lid (2) for a closed container incorporates an opening which can be closed by a door (5) provided with side walls (18) so that even when the door is open, the only access to the interior of the container is through a slot (8) in a wall (7) of the door unit. Needles or other sharps may be introduced through the opening (8) into the container for safe storage. When the door (5) is pushed down to close the opening, a two-part live hinge formed by grooves (14) acts to bias the door into the closed position. Re-opening is achieved by pressing on the flange (6) incorporating the grooves (14). A flap (21) provides a secondary closure device.

Abstract: The present invention provides a child resistant container suitable for packaging of medicines and the like wherein a bottom portion designed to hold the product and a cover member have first and second cooperative locking devices with the first locking device permitting a certain limited movement while maintaining a locked position such that when the second locking device is moved to an unlocked position, the first locking device remains locked until a second step or operation is performed thereon. Operation of the second locking device to unlock it tends to reinforce the locking action to the first locking device to prevent simultaneous unlocking of both locking devices.

Abstract: A sealing device for sealing the surface of contents of a container comprises a disc-like member having a central portion and a flexible perimeter and having a centrally located upstanding hollow handle having a purge valve at the upper end thereof. The purge valve has a closed position for preventing egress of air upwardly through said hollow handle and an open position to permit free passage of air therethrough. The disc-like member is contoured to correspond with the shape of the interior plan of the container.
