A tamperproof bag includes a base, a pair of opposing end walls, and a pair of opposing sidewalls extending upwardly from the base to form an open upper end, defining an interior volume. Each end wall includes a height greater than a height of each sidewall, allowing for easier handling. An adhesive strip is disposed on an interior-facing surface of at least one end wall. The adhesive strip is configured to secure the end walls together to form a sealed closure and prevent access to the interior volume. Separation of the pair of end walls once adhered forms a tear in the bag, which may identify that an unauthorized access attempt to the bag has been made and prevents reclosure of the bag. A tab connected to a perforated strip that aligns with the adhesive strip provides a mechanism for accessing the interior of the bag.

The present invention regards a container comprising a support having a base, a lateral wall and an abutment flap emerging from the lateral wall. The container comprises a closure system movable between a closed condition and open condition, a first coupling portion carried by the closure system and a second coupling portion defined on the abutment flap. The first coupling portion is movable between a first operating position in which it is disengaged from the second coupling portion and a second operating position in which it is engaged with said second coupling portion. The first coupling portion comprises a central body from which a tab emerges that is engageable with the second coupling portion; the first coupling portion defines a removable portion configured for being separated from the closure system following a first opening of the container following an engagement between said first and second coupling portions.

An easy-tear-open and tamper-evident container including: a container body having a first convex loop on a periphery of an opening thereof; a lid having a second convex loop for engaging with the first convex loop, where a loop of tear line is provided on a topmost surface of the second convex loop, and the loop of tear line is divided into a section of breakable line and a section of broken line; and a spacer part being disposed below a local area of the topmost surface of the second convex loop that bears the section of broken line to make the local area bent up to form an force application part.

A tamper evident container includes a base with a base rim adjoining a base hinge panel and a lid with a lid rim adjoining a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.

A tamper-evident coupling system includes a first base portion, a second base portion, a first coupling portion supported by and extending from the first base portion, and a second coupling portion supported by the second base portion and configured for cooperating with the first coupling portion. The first and the second coupling portions are configured for defining an arming condition in which the first and second coupling portions are stably engaged with each other. At least one of the first and the second coupling portions includes a removable portion that is separable from the tamper-evident coupling system upon a first disengagement of the first and second coupling portions following the arming condition to prevent a subsequent coupling between the first and second coupling portions and to show a tampering with the tamper-evident coupling system.

A container includes a base defining a perimeter opening and a top surface within the perimeter opening. The top surface includes a plurality of discrete openings defining respective compartments extending downwardly from the top surface of the base. A first recloseable lid covers the perimeter opening when the container is closed to resist transfer of solid matter between the compartments of the base. An additional recloseable lid encloses one of the compartments to resist liquid from exiting the compartment when the compartment is closed.

A container may include a base having a bottom and a plurality of side walls extending upward from the bottom to define an interior therebetween, and a lid configured to engage with the base in a closed configuration to enclose the interior. The container may also include a connecting portion by which the base and the lid may be connected in an initial state. The base may have an extension portion extending laterally outward from a lateral side of the base and connected to the connecting portion via a folding line about which the connecting portion and the lid may be rotatable with respect to the base between the closed configuration and an open configuration. The lid may also have an extension portion extending laterally outward from a lateral side of the lid and connected to the connecting portion via a tear line. The tear line may be weakened such that the lid may be separable from the connecting portion and the base at the tear line while the connecting portion may remain intact with the base.

A transparent, plastic, one-piece, tamper-resistant/evident container includes a cover portion including an outwardly extending peripheral flange and a base portion having an upper peripheral rim. A tamper-evident hinge joins the cover portion with the base portion. The hinge includes a frangible section. When the container is closed, the outwardly extending peripheral flange of the cover portion abuts the upper peripheral rim of the base portion and the upper peripheral rim of the base portion extends beyond an outer edge of the outwardly extending peripheral flange of the cover portion and deters opening the container.
