A tamper-evident container closure (10) is provided and comprises a base (15) and a lid (20). The base and lid are connected together by a hinge (25) so that the lid can be moved between a closed position and an open position. The base is attachable to a container neck. Generally opposite the hinge the lid includes a retention member (35), the retention member includes or defines a window (39) and includes a retention portion for engagement with a cooperating portion on the closure and/or on a container neck for holding the lid in a closed position. The closure includes a tamper-evident member (40) at least part of which moves into or out of view with respect to the window to indicate opening of the closure.

A plastic container includes a lid adapted for leak-proof sealing state with a base. Mating surfaces of the lid and base rims form one or more proximal seal zones when the lid rim and base rim are in an initially sealed state. Hinge-forming structure extends from a first hinge-joining section of the lid rim to a second hinge-joining section on the base rim. In the initially sealed state the first hinge-joining section superposes over all or part of the second hinge-joining section, the area at which the first hinge-joining-section superposes the second hinge-joining section defines an overlapping portion of the first and second hinge-joining sections. One or more vent channels are formed in either of the lid rim or base rim and located within the radially overlapping portion. The one or more channels form a complete discontinuity in the one or more proximal seal zones. Because the channels are within the overlapping portion, they are protected from tampering access.

A package that includes a container and a container closure having a vacuum-indicating pull tab. The container includes a longitudinal axis extending therethrough, a mouth, and a sealing surface. The container closure includes a seal membrane sealingly and removably coupled to the container sealing surface to seal the container, and a pull tab configured to extend from the seal membrane. Manipulation of the pull tab provides an indication of the presence or absence of a vacuum in the package.

A system and method for storing, shipping, and displaying produce in a box which has a tamper-evident closure. The box may be formed of folded cardboard and a transparent plastic lid which engages top edges of the box. The lid has a plurality of tabs around its periphery that may be bent and inserted into slots or notches formed in the box edges, and then expand to a larger relaxed size. The slots or notches have perforated lines enabling the lid to be ripped upward to open the box, thus indicating that the container has been tampered with.

A tamper evident container includes a cover having a first interlocking flange with a first tab for opening and closing the container and a first extension joined to the first tab along a frangible score line, a base having a second interlocking flange with a second tab for opening and closing the container and a second extension joined to the second tab along a frangible score line, the first extension including one or more first interlocking elements and the second extension including one or more second interlocking elements, where the first and second interlocking elements, 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 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 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.

The present invention relates generally to the field of closure devices for consumer products, including both liquid and dry products. More specifically, the present invention relates to a lid or closure for consumer goods packaging that provides a secure locking engagement to prevent spilling, leakage, and/or tampering of the contents of the packaging. The unique closure device utilizes a combination of a release tab and locking elements, which cooperate with one another in order to seal or unseal at least a portion of the lid or closure to allow for dispensing of the contents of the container.
