A flip-top closure includes first and second polymeric closure portions. The first closure portion includes a top wall portion, a sealing mechanism and an annular skirt portion. The second closure portion includes a tamper-evident band. The closure portions are attached by a line of weakness. The closure portions are further attached via a hinge. The hinge includes a locking tab, a flexible tab and linking segments. The locking tab extends further outwardly from a center of the closure in a closed position than the flexible tab and the linking segments. During the opening of the flip-top closure, the locking tab moves and passes the flexible tab such that the flip-top closure locks in a fully open position.

A method of manufacturing a tamper-evident closure, comprising the steps of: forming a body having a base and a lid; and inserting a dispensing member and a tamper-evident member into the body.

A method of manufacturing a tamper-evident closure, comprising the steps of: forming a body having a base and a lid; and inserting a dispensing member and a tamper-evident member into the body.

The present invention relates to a dispensing closure comprising a base element, which can be attached to a neck of a container, a flip-top lid, being attached to said base element by a hinge and being movable between a closed and an opened position, and a tamper-evident element extending in a circumferential direction around at least part of the circumference of said dispensing closure, wherein the tamper-evident element has at least one weakening region extending at least over part of the height of the tamper-evident element and/or wherein a shoulder region of the base element, to which frangible elements of the tamper-evident element are attached, is inclined such that it declines in an outward direction of the base element.

A tamper-evident closure for containers includes a closure shell having a top surface and a depending skirt. The top surface defines a first aperture therethrough and a frangible portion. The skirt defines an open lower end for engaging a container. A tamper-evident tearable member overlies the top surface of the closure shell and defines a second aperture overlying the first aperture. A removable closure cap overlies the top surface of the closure shell and the tearable member. The closure cap has an annular ring projecting downwardly from an underside of the closure cap and extending through the first and second apertures. The annular ring attaches to an underside of the frangible portion. At least partial removal of the closure cap from the top surface of the closure shell peels the frangible portion away from the top surface of the closure shell along the scoring, and tears the tamper-evident member.

A combination of a closing element (28) and a receiving structure (24) is provided wherein the closing element (28) and receiving structure (24) are in an initially assembled orientation which prevents, but which can be subsequently operated to permit, communication through the receiving structure (24). The receiving structure (24) includes at least one laterally projecting shear member (40) and a spout (30) defining (A) an access passage (32). The closing element (28) has an aperture (78) for receiving a shear member (40) of the receiving structure (24). At least one frangible bridge (78) extends across a portion of the aperture (74) for being severed by the shear member (40) during relative rotation between the closing element (28) and the receiving structure (24).

A container includes a base and a lid. A peripheral wall of the base terminates in a sealing flange extending outward from the peripheral wall of the base. The sealing flange includes a rail and a rim defining a groove therebetween. An upper surface of the lid terminates in a downwardly extending peripheral shoulder and an outwardly extending peripheral flange positioned outward from the downwardly extending peripheral shoulder. The outwardly extending peripheral flange of the lid abuts the rim when the container is closed. The rim extends beyond an outer edge of the outwardly extending peripheral flange of the lid substantially around the perimeter of the container. At least one surface of the downwardly extending peripheral shoulder engages at least one surface of the groove at a seal interface. The rail impedes the downwardly extending peripheral shoulder from moving in a direction away from the seal interface.

Closure device comprising a base (100) and a lid (200) articulated by a hinge (205) comprising at least one opening indicator (207) allowing the user to know that a container has been opened at least once. Prior to the first opening, the opening indicator (207) is attached to the lid (200) by at least one separable connector (208), said separable connector (208) being broken on the opening of the container. The base (100) further comprises at least one housing (111) that receives the opening indicator (207) after its separation and shows it to the user through at least one window (112).

Tamper evident clamshell containers include a first half hingedly coupled to a second half. The first half has a first closure edge with a tamper evident closure frangibly coupled thereto and the second half has a second closure edge with an engagement feature. The tamper evident closure can be coupled to the engagement feature to close the container. A force necessary to decouple the tamper evident closure and the engagement feature is greater than a force necessary to frangibly decouple the tamper evident closure from the first closure edge of the first half of the container.

A flip-top dispensing closure (10) is provided. The closure comprises: a base (12) connectable to a container neck (1); a lid (14) hingedly connected to the base so as to be movable between a closed position and an open position; and a dispensing member (20). The closure further comprises a tamper-indicating member (5). The tamper-indicating member (5) activates either: upon first opening of the lid (14); or if the base (12) is removed from the neck (1).
