Abstract:
A cap configured to close a container including a neck is disclosed herein. The cap includes at least one protruding element configured to cooperate with a slot situated on the neck such that the cap goes from a first position to a second position. The cap also includes at least one opening situated on an upper wall of the cap that is aligned with the at least one protruding element of the cap. The cap yet further includes a sealing element configured to impart sealing between the cap and the neck. The sealing element is radially offset relative to the protruding element.
Abstract:
A container and closure includes a closure secured to the container through projections comprising a series of horizontal, circumferentially spaced apart elements arranged so that the elements on the closure can pass though the spaces between the elements on the container and locate beneath them to secure the closure to the container. The elements of the projection on the container are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction and the elements of the projection on the closure are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction. The closure carries a sealing member for providing a seal with either an internal or external sealing surface of the container. The seal is driven down from a lead-in surface to engage the sealing surface as the closure is rotated.
Abstract:
A closure that includes a top panel and a skirt extending downwardly from a peripheral edge of the top panel is provided. The skirt terminates in a plurality of spaced thread engagement flanges for engaging the thread of the neck of a container. The closure includes a polymer-filled channel which connects the top panel to the skirt. When engaged with the threaded neck of a container, the neck is forced into the channel and engaged by the polymer so that the channel and polymer provide lateral rigidity to the neck. This rigidity prevents the neck from deflecting from the forces resulting between the threads and thread engagement lugs when the forces therebetween are increased to the level required to adequately seal the closure to the container.
Abstract:
A beverage container (1) comprises a container body (3) including an opening, a cap (5) to close the opening, and a collar (7), mountable on the container body (3). The cap (5) and the collar (7) include cooperating securement means (19, 21) by which the cap (5) may be secured to the collar (7), thereby securing the cap (5) to the container body (3) when the collar (7) is mounted on the container body (3). The cap (5), the collar (7) and the container body (3) are configured such that removal of the cap (5) from the container body (3) causes removal of the collar (7) from the container body (3).
Abstract:
A beverage container comprising a container body (3) including an opening and a plurality of recesses (80) in an exterior surface thereof, a cap (5) for closing the opening, and a collar (73) having a plurality of flaps (13) engagement with the recesses (80) to mount the collar (73) on the container body (3), the cap (5) and the collar (73) being connected to each other by a screw thread such that when secured together the collar (73) and hence the cap (5) is secured to the container body (3).
Abstract:
A container closure system including a container cap and a container closure may be frictionally mated such that projections in the container closure removably lock interior projections of an opening in the container cap in spaces defined in the container closure projections to hold the container cap on the container closure.
Abstract:
An apparatus for molding a cap (16) including a base portion (18) and peripheral skirt (20) extending axially from and about the base portion (18) includes an outer surface forming mold (44) for forming an outer surface of the base portion (18) and the peripheral skirt (20) and an inner surface forming mold (46) seatable within the outer surface forming mold (44) for forming an inner surface of the base portion (18) and the peripheral skirt (20). The outer surface forming mold (44) is retractable from seated engagement with inner surface forming mold (46) for exposing the moded cap (16) therebetween. The inner surface forming mold (46) includes a core portion (52) and lug forming mold portions (54) disposed radially peripherally thereabout, the lug forming mold portions (54) being able to project axially from and retract radially inwardly relative to the central core portions (52) for releasing and ejecting the molded cap (16)from the inner surface forming mold ( 46).
Abstract:
A child-resistant package includes a container having a neck finish with an open mouth, an angularly spaced array of external projections with notches on undersides of the projections, and a conical internal surface around the mouth. A closure has a base wall, a first annular wall with angularly spaced internal lugs received within the notches, and a second annular wall disposed radially inwardly from the first annular wall and in resilient sealing engagement with the internal surface on the container neck finish. The second annular wall has a substantially cylindrical portion adjacent to the base wall and a conical portion extending from the substantially cylindrical portion at an angle inwardly from the first annular wall and away from the base wall. The conical portion of the second annular wall has an edge remote from the base wall that is spaced from the internal surface of the container neck finish. This angulated free edge of the second annular wall helps prevent interference between the second annular wall and the container mouth during automated application of the closure to the container neck finish.
Abstract:
A cap and vial system which allows a common cap to be used to seal each of several sizes of pharmaceutical vials, thus precluding the need for pharmacists to maintain an inventory of a differently sized cap for each specific vial size. Each of the vials has a mouth opening of common diameter, with smaller vials being tapered down at a location beneath the mouth opening a greater amount than larger vials which are not tapered down as much. The cap may be reversible to engage with the differently sized vials in a child-resistant manner on one side of the cap, and in a non-child-resistant manner on the other side of the cap.
Abstract:
A safety cap and container is disclosed which is resistant to accidental opening. Such a cap and container include cooperating ratchet means on the cap and the container which normally hold the cap against undesired movement with respect to the container. A tapered internal surface is provided in the container and an internal resilient dependent member is provided on the cap so as to engage the tapered surface. Such engagement normally holds the ratchet means so that the cap cannot be moved with respect to the container. When, however, pressure is applied to the cap above the dependent member, this member is deflected by the tapered surface so as to allow movement of the cap so as to disengage the ratchet means, permitting the cap to be removed from the container.
