Abstract: A single-use, snap-over cap for use primarily in healthcare settings in order to maintain the integrity of a medication solution. The cap has a tapered cylindrical skirt, a puncture resistant lid portion, and one or more latch tabs. When placed onto a flanged injection port such as is found on a conventional fluid container, the latch tabs engage and flex about the port flange. After the cap is placed, the latch tabs engage the port flange to prevent upward axial movement relative to the port, thereby preventing removal of the cap and thus deterring unwanted or erroneous drug administrations or withdrawals.

Abstract: A system includes a container including a sidewall and a closure plane attached to the side wall and including an opening, a neck region on the sidewall being adjacent to the closure plane. The system also includes a closure including a cap closure with a fitment adapted to fit in the opening, a circumferentially depending outer skirt adapted to secure the closure to the neck region of the container, and a hinge attached to the cap closure and the circumferentially depending outer skirt. A method for sealing a closure on a container includes pivoting the closure about a hinge towards a closure plane and engaging a fitment with an opening to provide a friction fit. A method for opening a container having a closure includes disengaging a fitment from an opening and pivoting the closure about a hinge away from a closure plane.

Abstract: A container for use with a closure is provided, and includes a receptacle, a neck extending therefrom, a closure-engaging thread segment arranged on the neck of the container to engage the closure thread segment arranged on the closure, and a plurality of spaced apart protrusions protruding radially toward the closure from the neck of the container, the plurality of spaced apart protrusions forming a protrusion pattern that has a composite orientation that is helically opposite that of the closure-engaging thread segment to engage and to separate the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck. With this structure, the closure and container system provides an improved anti-backoff, tamper evident closure and container system that reduces torque used to initially apply the closure to the container and improves reliably by reducing stress on the component parts, while desirably preventing backoff from occurring.

Abstract: There is described a neck structure in combination with a closure. The neck structure defines a neck opening with a cylindrical sealing surface surrounding the neck opening and an external neck surface. The closure comprises a cap formed of resilient material having a top and a downwardly extending skirt portion depending from the top. An annular plug depends from an underside of the top and one or more ribs are formed on an internal surface of the downwardly extending skirt portion. The annular plug and the one or more ribs are arranged concentrically and are dimensioned such that, upon application of the cap to the neck structure, the annular plug projects into the neck opening and engages the cylindrical sealing surface. At the same time the one or more ribs engage the external neck surface.

Abstract: A cap with a tamper-evident ring is designed to snap engage a container that is provided with an upper and lower bead. A ring of teeth provided along an inside skirt of the cap engage teeth located along an inside wall of the container. When the cap is snapped onto the container, both sets of teeth automatically engage and a plug seal provided on the cap engages the container upper bead. By turning the cap clockwise or counterclockwise, the side angles of the teeth force the cap to disengage upwards over the upper bead and unsnap from the container. When the closure is opened for the first time, the ring breaks away from the cap and slides down the container below the lower bead, which keeps the ring from coming off the container and provides evidence that the cap had been opened.

Abstract: There are various ways to latch a closure onto a container. It has been found that for blowmolded containers that the support flange for the bottle preform can later be used as a part of the latch mechanism to secure a closure onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mole, the preform is heated to about 85oC to about 200oC. During this time and in the mold, it will be supported by the support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure will have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Abstract: An improvement in a unit closure for a vial container, which helps ensure the smooth depression of the unit closure with a relatively small force from the air-expelling posture to the hermetically sealing posture and eliminate a fear of destroying the unit closure and container in depressing the protector whereby hermetic sealing and tamperproof are achieved. To this end, the locking means is of flexible locking tongues arranged such that they are inclined diametrally inwardly of the skirt and upwardly towards the ceiling of the protector, whereby, upon depressing the unit closure to its hermetically sealing posture, the locking tongues deflect radially outward of the skirt and, on completion of the depression of the unit closure, the locking tongues snap resiliently into place underneath a flange of the mouth of the container to hold firmly the unit closure in the hermetically sealing posture.

Abstract: A child-resistant adult-friendly prescription storage vial is presented with an over-cap which can only be removed from the vial by first orienting the cap at a particular point on the vial and then depressing a pair of push-tabs on the cap. When the cap is properly oriented the push-tabs mechanically operate a pair of locking tabs on the vial which hold the cap in place. The locking tabs are designed so that an extended lip on the tab interlocks with a slit on the cap and can only be removed from the slit when the push-tabs on the cap are manually operated.

Abstract: Disclosed is a closure for a container, such as a blow molded jug having a neck surrounding an opening therein, the closure having a first annular portion and a second annular portion. The first annular portion in the closure has a wiper seal and a lip seal. The second annular portion exerts an upward pressure on the lip seal which causes improved sealing and leak-tight properties during shipping, handling, etc. The upward pressure also enhances the effectiveness of the wiper seal. The second annular portion may include an annular tear skirt having a pull tab for the removal thereof to facilitate removal of the closure from the container. The closure may also include a plug seal, and a lower annular portion extending from the second annular portion.

Abstract: A new and improved end-cap for use with a fluid heater is disclosed.

A first side wall separates the first and the second grooves, and a second side wall separates the second and the third grooves. The first and the second side walls each are relatively thin which facilitates deformation in a radial direction in response to differential thermal expansion of the end cap in relation to the tubes. In addition, the side walls compress in a circumferential direction in response to differential thermal expansion of the end cap in relation to the tubes. An annular flange is positioned radially inward of the second side wall to facilitate centering the third tube in the third groove.
