A container including a base having a first flange extending from a side of the base; a lid having a second flange extending from a side of the lid, wherein the first flange and second flange are coupled together at a living hinge, a first perforation cut positioned on the first flange or the second flange, a plurality of bubbles or raised portions positioned on the flange which does not have the first perforation cut, wherein the bubbles or raised portions are positioned over the first perforation cut when the lid is closed on the base, wherein when the bubbles or raised portions are pressed down onto the first perforation cut, the first perforation cut is broken to separate the lid from the base, and wherein the bubbles or raised portions are deformed when they are depressed to provide a visual indication that the container has been opened.

A tamper evident container includes a cover with a first interlocking flange with a first tab for opening the container and a first extension joined to the first tab along a first frangible score line, a base with a second interlocking flange with a second tab for opening the container and a second extension joined to the second tab along a second frangible score line, a rim extending around a perimeter of the base, the rim having a flat portion connected to an outer wall, and a flange portion extending from the outer wall portion, wherein a position of the flat portion and the flange portion correspond to a sheet line, and wherein the first and second interlocking flanges, when securely fastened together, prevent access to the first and second tabs, and require more force to separate than to sever the first and second extensions along the frangible score lines.

A cap for accommodating a compound includes a body with an opening. The opening penetrates from an upper to a lower end portion of the body by a first length. A membrane seals a lower end portion of the opening. A lid is removably coupled and moveable relative to the body. The lid includes a protrusion extending downwardly from an interior surface of the lid by a second length greater than the first length. The opening accommodates a lower end portion of the protrusion. A spacer removably couples with the lid and interposes between the lid and the body. The spacer configurable between a first state in which the spacer is engaged with the lid, which prevents the protrusion from penetrating the membrane, and a second state in which the spacer is disengaged with the lid, which allows the protrusion of the lid to penetrate the membrane of the body.

A tamper-evident closure comprising a cap and a retaining ring, the retaining ring is connected to the sidewall by a plurality of bridges, at least one of the bridges is frangible and at least one of the bridges is non-frangible whereby to form a link between the ring and the sidewall.

A flip top cap for containers providing evidence of first opening includes a cover part and a pourer part coupled by a hinge arrangement and produced as a single piece. The cover part is rotatable around the hinge arrangement to be brought from a closed position engaging the pourer part to an open and separate position with respect to the pourer part, an engagement system engaging the cover part after rotation into a closed position on the pourer part. The engagement system is breakable and is arranged partly on the cover part and partly on the pourer part, and remains integral with at least one of the cover or pourer parts when they are broken at the first opening.

An apparatus and a method are provided for a container cap comprising a plurality of tamper evidence bridges configured to provide evidence that the container cap has been removed from a container by other than a manufacturer of the container. The tamper evidence bridges comprise a small tab of material that extends from a bottom-most edge of the container cap to a neck ring of the container. The tamper evidence bridges are configured to break, or snap, when the container cap is rotated relative to the neck ring. Broken tamper evidence bridges provide readily visible evidence to an end-user of the container that the container cap has been removed by other than the manufacturer of the container. The high visibility of the tamper evidence bridges serves to discourage vendors from attempting to refill and resale of the used containers.

A closure includes first and second closure portions. The first closure portion includes a polymeric top wall portion and an annular skirt portion. The skirt portion includes exterior and interior surfaces. The interior surface includes an internal thread formation for mating engagement with an external thread formation of a container and at least one rotation-inhibiting projection. The rotation-inhibiting projection is located to contact the external thread formation. The rotation-inhibiting projection is in the general shape of the letter “C” prior to engagement with the external thread formation of the container. The second closure portion includes a polymeric tamper-evident band.

A tamper evident device, comprising: a container; a valve; and a cap; wherein both the valve and the cap may each have a tamper evident device. The cap and the valve are configured to matingly engage in a closed and open position, such that any excess liquid is recaptured and directed back into the container. The tamper evident devices may be rings and frangible bridges that snap or break when the device is tampered with or opened.

Closure assembly comprising a spout (1) and a cap (2) including a tamper-evident ring (3). The spout (1) has a neck (14) around a product passage (15) and a wall (10). The wall is spaced from the neck (14) to form an inner space (11) which is open from above to receive the tamper-evident ring (3). The tamper-evident ring (3) is integrally moulded via breakable bridges (34) to the cap and comprises a base portion (32) with at least one snap portion (33) at abase portion outer face (32a). The wall (10) of the spout (1) comprises at least one window (16), wherein the at least one snap portion (33) fits inside the window (16) to snap the tamper-evident ring (3) to the spout (1) when the tamper-evident ring (3) is inserted in the inner space (11).

A tamper-evident closure (10) for a container mouth, comprising a cap and a retaining ring arranged under the cap for retaining the closure on the container, the cap is separable from the ring, the cap and ring are joined by a pair of arms (37, 39), the arms are non-frangibly connected to a common root (40) at one end, the other end (36) one of the arms is non-frangibly connected at a circumferentially clockwise location from the root and the other end (38) of the other arm is non-frangibly connected to a circumferentially anticlockwise location from the root, whereby the arms permit axial separation of the cap from the ring and assume a generally V-form configuration when doing so and whereby the cap remains tethered to the ring.
