Disclosed herein are foilless caps. In an implementation, the foilless caps provide sealing of the container without the use of a foil and are environmentally friendly. In an implementation, the foilless caps include tamper evident mechanisms to provide evidence of prior or attempted use. In an implementation, the foilless caps further include tether mechanisms to prevent loss of the cap after opening. In an implementation, the foilless caps provide sealing and resealing of the container with enough closure to maintain freshness. In an implementation, the foilless caps provide a non-backoff feature which may include audible and tactile indications to the user that the container is closed. In an implementation, the foilless caps may provide mechanisms to hold an opened and tethered cap away from the container opening during use.

A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference.

A closure includes first and second closure portions. The first closure portion includes a top wall portion and an annular skirt portion that includes an internal thread formation. The second closure portion includes a tamper-evident band being at least partially detachably connected to the skirt portion by a frangible connection. The tamper-evident band includes first and second portions connected via a bending area. The second portion extends generally upwardly from the bending area towards the top portion and is located inwardly from the first portion of the band. The second portion of the band includes a tab portion and an extension portion. The extension portion is located further from the bending area than the tab portion. The average thickness of the tab portion is greater than the average thickness of the extension portion. The extension portion extends continuously around an entire inner circumference of the closure.

A closure for a container includes a closure shell having a first interior surface, a tamper evident band having a second interior surface, and a flexible hinge. The flexible hinge includes a first end, a second end, and a gathered portion located between the first and second ends. The first end is coupled to the closure shell and the second end is coupled to the tamper evident band. At least a portion of the gathered portion extends radially inward with respect to the interior surface of the closure shell. The flexible hinge permits the closure shell to be opened and remain tethered to the tamper evident band. The closure may further include a retaining bead or ratchets to keep the tamper evident band attached to the container.

A cap (1) for a container comprises: a body (2), configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring (3) is joined to the cap body (2), the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).

A plastic cap is able to be applied to a container having a screw formed with a vent. The plastic cap has an outer ring for sealing at least the outer surface of the mouth of the container, and an inner ring for sealing the inner surface of the container mouth. In a closed state, sealability is maintained by a seal point on the inner surface of the outer ring. In an unsealing step, a seal point on the outer surface of the inner ring is shifted into a pressure-contacted state on the inner surface of the container mouth, where there is no risk of sink marks caused by molding strain, before a seal by the outer ring is released. Thus, reliable sealability can be exhibited even when the cap is applied to a container having inferior dimensional accuracy.

The present invention relates in particular to a closure (3) for the fluid-tight closing of a vessel (2) filled with a substance (5), wherein the closure (3) is provided with a fluid-tight pressure-transmission element (9) and wherein the closure (3) is provided with a base body (8) to which the pressure-transmission element (9) can be attached in a fluid-tight manner, wherein the pressure-transmission element (9) is deflectable by pressurisation without incurring damage, for biological inactivation of microorganisms present in the substance (5), wherein the closure is configured in such a way that the pressure-transmission element (9), when the vessel (2) is closed with the closure (3), is held (clamped between the vessel (2) and the base body). The invention also relates to a corresponding container (1) and a corresponding method.

A cap for a container is made of a material at least part of which is derived from natural fibres. The cap comprises a cup-shaped body having a skirt which extends around an axis and a transversal wall arranged transversally to the axis. A cavity is defined inside the cup-shaped body. The cup-shaped body is delimited by an inner surface facing the cavity and by an outer surface facing the opposite way to the cavity. At least one projecting element projects from a surface of the cup-shaped body selected from either the inner surface or the outer surface. At least one recess is provided at the projecting element on another surface of the cup-shaped body selected from either the outer surface or the inner surface.

This invention is an improved stopper for a bottle with a tethered plastic stopper where its closure shell remains attached to its tamper band after bottle opening. The tethered plastic stopper includes a closure shell that remains attached to its tamper band after the bottle is opened through a linking feature. The invention also includes a method for making a stopper.

A fluid container closure system includes a fluid outlet, a neck finish adjacent to the fluid outlet, wherein the neck finish includes a retaining rim, protruding in a radial outward direction and encircling the neck finish. A screw cap includes a base with a top deck and a skirt and a tamper evident band with a base having a lateral inner surface. The screw cap includes a predetermined breaking structure along which the skirt and the tamper evident band are interconnected. The tamper evident band includes a lip extending along the inner lateral surface of the tamper evident band base and inwardly therefrom, wherein the lip includes a hinge section and a retaining surface configured so when the screw cap is initially applied to the fluid container, the lip is folded upward about the hinge section such that the retaining surface in an applied position of the screw cap is positioned underneath the retaining rim.
