A bottle cap includes a body and a security ring. The body has multiple breakable bridge portions located along the periphery of the body and connected to the security ring. Two non-breakable plates are connected between the body and the security ring. Each of the non-breakable plates includes multiple turning positions and multiple angles. When the multiple breakable bridge portions are broken, the non-breakable plates are still connected to the security ring. The non-breakable plates are extendable so that the body can be pulled away from the security ring for a distance.

A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

A container preform for forming a plastic container includes a neck with a finish portion including an opening and one or more threads disposed on the finish portion for rotatably engaging with a closure to seal contents within an interior of a container formed from the preform. At least one of the one or more threads includes a main thread body, and a thread start configured to guide a thread of the closure into engagement with the main thread body. The thread start being biased towards the opening.

A closing cap for closing a container comprises a cylindrical threaded part having an open edge and an internal screw thread, which can interact with an external screw thread of the container neck. A tamper-proof strip is configured to be retained on an annular protrusion formed on the container neck. A retaining strip has a first and a second end and a first and a second edge. The first end is fixedly connected to the open edge of the threaded part, and the second end is fixedly connected to the tamper-proof strip. The first edge is detachably connected to the open edge of the threaded part by a predetermined breaking element, and the second edge is detachably connected to the tamper-proof strip by a second predetermined breaking element. The first predetermined breaking element and the second predetermined breaking element have different tensile strengths or tear strengths.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

A closure can close an outlet of a vessel. The vessel outlet can comprise a tubular cavity with an interior surface. The closure can comprise a male portion comprising a distal undersized portion, a proximal oversized portion, and a taper between the undersized and oversized portion. The male portion can be inserted in the vessel outlet, undersized portion first. Interference between the inner diameter of the vessel outlet and the outer diameter of male portion can occur when the male portion is sufficiently inserted. The interference can cause the undersized portion to flare out and engage the interior surface of the tubular cavity, thereby providing a seal.

A closure for a container includes a top panel, a skirt depending from the top panel and extending circumferentially about a central axis, a tamper-evident band attached to the skirt, and at least one thread extending from an interior surface of the skirt. The skirt extends from a first end attached to the top panel to a second end opposite the first end. The skirt is tapered radially outward from the first end to the second end such that a diameter of the skirt at the second end is greater than the diameter of the skirt at the first end.

A closing element (28) for restricting communication of a substance through an access passage (34) of a body (24) includes a first portion (68) for being removably affixed to the body (24), the first portion (68) having an inner wall (80), an outer wall (96) surrounding the inner wall (80), and at least one bridge (100) connecting the outer wall (96) with the inner wall (80). The closing element (28) has a second portion (72) for being non-removably affixed to the body (24) and a movable connecting element (76) extending between the first portion (68) and the second portion (72). The closing element (28) has an unactuated configuration wherein a major portion (78) of the length of the connecting element (76) is located laterally between the inner wall (80) and the outer wall (96) to shield the major portion (78) of the length of the connecting element (76).

A closure for a container includes a top panel, a skirt depending from the top panel and extending circumferentially about a central axis, a tamper-evident band attached to the skirt, and at least one thread extending from an interior surface of the skirt. The skirt extends from a first end attached to the top panel to a second end opposite the first end. The skirt is tapered radially outward from the first end to the second end such that a diameter of the skirt at the second end is greater than the diameter of the skirt at the first end.
