A blank for forming a tamper evident container includes a plurality of panels connected together at fold lines configured for extending at least partially around an interior space, including a first side panel, a top panel, a second side panel and a bottom panel. A bottom flap is foldably connected to an edge of the bottom panel on the first end of the blank. A top flap is foldably connected to an edge of the top panel on the first end of the blank. The bottom flap includes a major flap and a minor flap, the major flap connecting between the bottom panel and the minor flap. The top flap includes a catch point feature and wherein the minor flap includes a trap aperture configured to catch the catch point feature of the top flap when opening a container constructed from the blank to provide a tamper evident access feature.

A stopper for a container with a lid with a peripheral wall engaging around the neck of the container and with an olive seal provided with an outer, peripheral annular bead for jamming engagement in the container opening includes an inner surface of the olive seal having a ribbed wall surface, which is defined by a plurality of grooves and webs extending in the longitudinal direction on the wall of the olive seal.

A tamper-evident carton and method of using same. The tamper evident carton may include a floor panel; side panels extending about a periphery of the floor panel; corner gussets extending between adjacent side panels, wherein the floor panel, side panels, and corner gussets may be configurable to form a compartment region; a lid flap extending from an uppermost edge of one of the side panels forming a moveable hinge joint therebetween, the lid flap may include a front edge flap extending from a front edge of the lid flap opposite that of the moveable hinge joint; and a tear strip disposed in the front edge flap.

A locking top for blocking a stopper in the neck of a vessel comprises an outer body and a cage that is configured to fit into and lock axially in the outer body. The cage comprises an upper ring, a plurality n of branches connected to the upper ring, n/2 median bridges and n/2 lower bridges arranged in alternation on the periphery of the cage, each connecting together two adjacent branches. When the top is in an intermediate holding position in which the stopper is partially pushed into the neck, the lower bridges surround, at least in part, a collar of the neck; the median bridges located, in an axial direction, between the upper ring and the lower bridges are designed to form an open space between them and the collar.

A PET container cap, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, is proposed. The cap includes a cap body which is provided on and coupled to the injection part so as to provide tight blocking for preservation of contents; and an end ring which is integrally formed at the lower side of the cap body, is restricted by an annular protrusion formed at the lower side of the outer circumference of the injection part, exhibits a sealing function enabling grasping of openness of the cap body, and causes transformation in a separation process of the cap body by a user, so that the end ring is simultaneously separated together with the cap body from the injection part.

A tamper evident carton. The tamper evident carton may include a floor panel; side panels extending about a periphery of the floor panel; corner gussets extending between adjacent side panels, wherein the bottom panel, side panels, and corner gussets may be configurable to form a compartment region; first and second lid flaps extending from an uppermost edge of their respective side panels forming first and second moveable joints, respectively, therebetween, and the first and second lid flaps may each include an interlocking feature, such that the first and second lid flaps may interlock with one another when in a folded closed configuration; third and fourth lid flaps extending from an uppermost edge of their respective side panels forming third and fourth moveable joints, respectively, therebetween, and the third and fourth lid flaps may each include an interlocking feature, such that the third and fourth lid flaps may interlock with one another when in a folded closed configuration.

A container closure for closing the pour opening-(33) of a container, has a screw cap with a free edge, ­a security ring connected by a break-off web to the free edge and has-engagement means, ­a first holding strip with first and second ends, the first end (39) is fixedly connected to the free edge and the second end fixedly connected to the security ring, and ­a second holding strip with third and fourth arm ends, wherein the third end is fixedly connected to the free edge (25) and the fourth end is fixedly connected to the security ring. The first, second, third, and fourth ends are arranged one after the other in the circumferential direction on the free edge and on the security ring. The length of the first and second holding strips are between 27% and 32% of the outer diameter of the screw cap.

A tamper-evident bag seal including tabs for separating flaps of the seal along a perforation is provided. The tamper-evident bag seal may be a paper or paperboard panel that folds over the handles of an existing bag and is secured to the sides of the bag. The tamper-evident bag seal includes a fold having perforated sections adjacent centrally located tabs. By pulling the tabs in opposite directions, the perforated sections are compromised, permitting access to bag contents and evidencing tampering of the bag seal.

Disclosed is a disposable lunch box, which includes an upper cover and a bottom box, the upper cover includes a cover body and a first clamping part connected with the cover body, the bottom box includes a box body and a second clamping part connected with the box body, the first clamping part and the second clamping part are configured for assembling the upper cover and the bottom box together. An easily broken rib is arranged between the cover body and the first clamping part, and an easily broken edge is arranged between the box body and the second clamping part, or the easily broken edge is arranged between the cover body and the first clamping part, and the easily broken rib is arranged between the box body and the second clamping part.

A method comprising obtaining a box comprising a box top defining a locking tab separable from the box top and comprising first, second, and third tab subpanels; the locking tab and the first tab subpanel thereof extending from at least one of a first main panel and a first end panel of the box, the second tab subpanel extending from and joined to the first tab subpanel, and the third tab subpanel extending from and joined to the second tab subpanel; and a box bottom comprising a second main panel; a second end panel joined thereto; and a tab connected to the second main panel and defining a locking opening; bending the third tab subpanel with respect to the second tab subpanel; inserting the locking tab into a gap defined at least in part by the second end panel; and engaging the locking tab with the locking opening.
