The skirt and the plug comprise sealing ribs (21, 22, 26, 27) that engage the lip of the container The ribs are located at substantially equal longitudinal distances from the base (3) of the closure.

Abstract: A container neck and closure assembly, wherein the container neck (10) comprises a first screw thread (14) on an internal surface thereof and the closure (12) comprises a cylindrical plug (32) for insertion into the container neck, said plug having a second screw thread (36, 37) on an outer surface thereof for engagement with the first screw thread to secure and resecure the closure on the neck.

Abstract: The invention provides a threaded container closure assembly includes: a container neck having an opening; a closure for said neck, the closure having a base portion and a skirt portion; a first screw thread on the neck, said first screw thread comprising one or more first thread segments; a second screw thread on an inner surface of the skirt of the closure, said second screw thread comprising one or more second screw thread segments; said first and second screw threads being configured to enable a user to secure, remove and resecure the closure into a sealing position on the neck by rotation of the closure on the neck; and wherein said first thread segments are shorter than said second thread segments; and wherein the second thread segments are each made up of one or more radially spaced projecting portions, each said portion extending radially no more than about 60° around the closure skirt.

Abstract: A closure assembly includes: a vessel opening; a closure for said opening, the closure having a base portion and a skirt portion; a first screw thread on the opening, said first screw thread having one or more first thread segments; a second screw thread on an inner surface of the skirt of the closure, said second screw thread having one or more second thread segments; said first and second screw threads being configured to enable a user to secure, remove and resecure the closure into a sealing position on the opening by rotation of the closure on the opening; wherein the first thread segments are shorter than said second thread segments; and wherein the second thread segments are each made up of one or more radially spaced projecting portions, each said portion extending radially no more than about 60° around the closure skirt.

Abstract: The invention provides a container closure assembly comprising: a container neck having side walls defining an opening at one end thereof and a lip extending around the opening, wherein an inner surface of the side walls proximate to said lip is inwardly tapered; a closure for said neck, the closure having a base portion and a skirt portion; a first screw thread on the neck; a second screw thread on an inner surface of the skirt of the closure; said first and second screw threads being configured to enable a user to secure, remove and resecure the closure into a sealing position on the neck by rotation of the cap on the neck; a sealing plug extending from said base portion of the closure inside and substantially concentric with said skirt portion of the closure, wherein the sealing plug comprises a plurality of circumferential sealing ribs on an outer surface of said sealing plug for engagement with said inner surface of the container neck when the closure is secured on the container neck; at least one flexib

Abstract: A closure assembly includes: a vessel opening; a closure for said opening, the closure having a base portion and a skirt portion; a first screw thread on the opening, said first screw thread having one or more first thread segments; a second screw thread on an inner surface of the skirt of the closure, said second screw thread having one or more second thread segments; said first and second screw threads being configured to enable a user to secure, remove and resecure the closure into a sealing position on the opening by rotation of the closure on the opening; wherein the first thread segments are shorter than said second thread segments; and wherein the second thread segments are each made up of one or more radially spaced projecting portions, each said portion extending radially no more than about 60° around the closure skirt.

Abstract: A container closure assembly that includes a container neck having an opening and a closure for the container neck, wherein the closure has a base portion and a skirt portion. A first screw thread on one of the container neck and the closure, the first screw thread comprising one or more first thread segments and a second screw thread on the other of the container neck and the closure, the second screw thread having a plurality of second thread segments, each of the second thread segment including upper and lower thread surfaces. A seal that forms a seal between the container neck and closure when the closure is screwed down on the container neck. Mutually engageable elements on the container neck and closure to block or restrict rotation of the closure in an unscrewing direction beyond an intermediate position when the closure is under an axial pressure in a direction emerging from the container neck.
