A closure for a container neck having a crown, a reduced diameter portion, a downward facing shoulder, and an enlarged diameter portion. The crown defines an opening and an outwardly extending locking bead. The closure includes a cap, a skirt, a well, a frangible membrane, a pull ring, and a retainer. The skirt depends from the top and is adapted to fit around the crown and the enlarged diameter portion of the container neck. The well includes an upper side wall depending from the top, an inwardly directed shoulder located adjacent a bottom of the upper wall, and a lower side wall depending from the inwardly directed shoulder. The lower side wall has an interior surface and the lower side wall terminating at an open bottom. The frangible membrane in the well closes off the well and includes a line of weakness frangibly connecting the frangible membrane to the lower side wall adjacent the inwardly directed shoulder. The pull ring is attached to an upper surface of the frangible membrane.

A closure for a container having a foil or membrane sealed opening. The closure includes a cap, a spout and a stem. The stem includes a downwardly extending piercing structure adapted for piercing the foil or membrane of the container upon rotation of the spout relative to the cap. The cap includes a cap top, a cap skirt depending from the cap top, an open sleeve and a stem guide. The open sleeve has an inwardly extending thread adapted to detachably engage the container. The open sleeve extends upwardly from the cap top. The stem guide extends along an internal surface of the sleeve. The spout rotatably engages the sleeve and includes a spout top having a central aperture, an outer spout skirt and an inner skirt. The outer skirt depends from the spout top radially outward of the sleeve and rotatably engages the sleeve. The inner spout skirt depends from the spout top radially within the sleeve.

A container including a neck and an opening, in combination with a tamper-evidencing closure including a top, a depending annular skirt and a tamper-evidencing band frangibly connected to the annular skirt. The container includes a locking surface on the neck spaced from the opening. The tamper-evidencing band includes an inwardly turned retaining rim that extends at least partially upwardly. The retaining rim has a free edge for engagement with the locking surface as the closure is removed from the neck. The retaining rim includes a locking surface engaging structure, most preferably provided by a plurality of outwardly directed flutes spaced circumferentially thereon and a second securing structure located on the retaining rim between the flutes. Drain passageways are provided in the rim to enable draining and/or evaporation of trapped liquid.

A closure for sealing the opening of a container. The closure may include an angled plug. The container includes an external thread configuration and the closure includes an internal thread configuration which are adapted to pass over each other with one of the external and internal thread configurations having at least one thread lead and the other having at least twice as many thread leads. The closure includes an inwardly turned retaining rim extends at least partially upwardly. The retaining rim has an attachment boss and an upwardly extending line of weakness adjacent the attachment boss such that when the closure is removed from the container, the line of weakness tears allowing the tamper-evidencing band to remain with the closure upon removal from the container. The closure may include a top having a periphery, an annular skirt depending downwardly from the periphery and including a lower edge and a line of weakness extending upwardly from the lower edge, a tear tab extending downwardly from the skirt below the lower edge, and a tamper-evidencing locking member including an inwardly extending locking ring that extends radially inwardly from the skirt intermediate the top and the bottom edge, the retaining rim including a free edge that is adapted to engage the radially extending locking bead of the container when the closure is removed from the container neck. A method of molding a closure including a tamper-evidencing band is also disclosed.

A closure for a container having an opening includes a base cap and an overcap that form a sealed chamber adjacent the opening that is isolated from the contents of the container. The base cap includes an outer skirt having container-engaging structure, a cylindrical well, a frangible membrane connected to the well along an inclined line of weakness and by a hinge member. The hinge member includes a pocket extending downward adjacent lower and upper terminuses of the line of weakness. The overcap includes a body having gripping structure, an inner skirt received within and rotatably connected to the well, and a cutting member depending from a lower end of the inner skirt received within the pocket such that the cutting member extends below the upper terminus. The cutting member severs the line of weakness upon substantial rotation of the overcap with respect to the base cap. A method of using the closure is also disclosed.

A closure for a container having an opening includes a base cap and an overcap that form a chamber adjacent the opening which is sealed from the contents of the container by a frangible membrane having an inclined line of weakness and by a hinge member having a pocket extending downward adjacent lower and upper terminuses of the line of weakness. The overcap includes a cutting member received within the pocket that severs the line of weakness upon substantial rotation of the overcap with respect to the base cap. A pushing member may cooperate with a cam member to deflect open the membrane upon severance. The pocket may include a stop for the cutting member. The base cap may include a cylindrical structure having an upwardly inwardly projection member to form a seal with an thickened upper portion of the overcap skirt to protect against penetration into the chamber.
