An apparatus includes a cap assembly and a container assembly. The cap assembly may be unscrewed from the container assembly by simultaneously pressing a predetermined combination of buttons available on the top of the cap assembly. If the predetermined combination of buttons is not precisely and exclusively selected, the cap assembly resists being unscrewed from the container assembly and a beverage inside remains inaccessible. A user of the apparatus who knows the correct combination of buttons will thereby be able to readily access the beverage in the container assembly, but one without that knowledge will not. Tampering is avoided.

A cover operates with a bistable snap-fit mechanism for positioning on a closable opening of a container or on another element to be closed by the cover. The cover and/or a container wall region has fitted thereon a tamper-evident sealing element to be removed when opening the container for the first time, which, prior to being removed, blocks deformation of the front wall necessary for changeover between the two bistable states and/or prevents an expansion portion necessary for the snap-fit mechanism, from bringing about alteration to the outer circumference of the cover necessary for deformation of the front wall of the cover between the two bistable states. As an alternative, or in addition, it is also possible for a handle member, necessary for pulling off the cover, to be configured such that it can only be used once the tamper-evident sealing has been successfully removed.

The present subject matter is directed towards a packaging container comprising at least one sheet of a packaging material defining a closed cross-section and open at an operative top end and an operative bottom end thereof. At least two flaps are provided at the operative top end and the operative bottom end of the at least one sheet, wherein the at least two flaps are sealable to each other to define an interior space for containing edible items therein. An auxiliary lid is provided on one of the operative top end and the operative bottom end, wherein the auxiliary lid is configured to snugly fit on one of the operative top end and the operative bottom end subsequent to the unsealing of the at least two flaps, thereby preventing ingress of air and other foreign matter into the interior space.

A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.

The invention is drawn to a container comprising a bottom wall and at least one sidewall extending upwardly from the bottom wall. The sidewall terminates in an edge and has an inner and an outer surface. The bottom wall and the at least one sidewall form a container interior. A flexible bag having an open end is disposed within the interior of the container and over the top edge of the container. A slide ring extends at least partially circumferentially about the outer surface of the sidewall and is affixed to the open end of the bag and frictionally engaged with the outer surface of the sidewall.

A package having a lid seated on a base where the edge of the seated lid is generally inaccessible, and where the edge is made accessible by a movement of a tamper-evident tab. The base and lid are configured so that opening of the tamper-evident tab locks the tab in the opened position. The inner edge of the tamper-evident tab is joined to the base by a hinge. The tamper-evident tab includes a protrusion that extends inwardly beyond the hinge. The lid includes a retention feature overlying the tamper-evident tab. The protrusion interacts with the retention feature to provide an audible indication when the tamper-evident tab is opened and to retain the tamper-evident tab in the opened position. The protrusion may be configured to lift the lid when the tamper-evident tab is in the opened position.

Disclosed is a box that includes a base and a lid connected by a hinge including at least one hinge portion connected to the lid by a frangible connection configured to break during the first opening of the lid. The box includes a tongue extending from the lid and beyond the articulation axis, such that when the box is closed, the tongue extends toward the outside of the box from the lid while protruding relative to the hinge beyond the articulation axis, pulling on the tongue making it possible to open the lid by breaking each frangible connection, a lid portion of each hinge part remaining secured to the base and separate from the lid, in the protruding state.

A plastic preform is provided that includes a hollow body portion including a closed bottom portion, a lower portion extending upwardly from the bottom portion, and a neck portion extending upwardly from the lower portion. The neck portion includes a support flange having an upper and lower surface, a tamper-evident formation, threads, and a dispensing opening positioned at a top of the neck portion. In an embodiment, the weight of the neck portion is 2.3 grams or less; and/or the vertical distance from the top of the dispensing opening to the lower surface of the support flange, including the threads and the tamper-evident formation, is 0.500 inches or less. Containers and methods for molding preforms and making containers are also disclosed.

A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.

A tamper-evident container includes a base and a lid. A base extension and a lid extension are connected to a hinge to join the base and the lid together in a closed, pre-use configuration. A tab extends from either the lid extension or the base extension in a direction away from the lid and the base such that the tab extends beyond the hinge. The tab is joined to one of the extensions via weakened regions that can be torn when the tab is pulled to indicate that the container has been tampered with or opened.
