A receptacle for minimizing evaporation of a fluid includes a single-piece body, a fluid-tight seal, a penetrable septum, and a lid coupled to the body. The body includes a first chamber having a first opening. The fluid-tight seal is affixed to a surface of the body that defines the first opening. The fluid-tight seal covers the first opening and is frangible. The septum covers the first opening and the fluid-tight seal. The lid has an opening axially aligned with the first opening. The septum comprises slits forming flaps The first chamber can be the only chamber containing a fluid, or the single-piece body may also include another chamber containing the fluid. The other chamber can be in fluid communication with the first chamber via a conduit. The fluid-tight seal can also cover the opening of the second chamber.

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 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.

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 closure device includes a first part forming a fastening base for fastening to a container neck and second part forming a lid. The second part includes a fastening ring and a hinge connecting the fastening ring to the lid and permitting the lid to pivot relative to the fastening ring between closed and open positions. The fastening ring snaps into a fastening groove in the first part. The second part has a first-opening indicator and a frangible connection between the first-opening indicator and a peripheral rim flange of the lid. A free space between the fastening ring and the first-opening indicator exists when the lid is in the closed position prior to the first opening. Two lock zones on the first part engage the first-opening indicator such that the first-opening indicator separates from the lid and drops into the free space upon the first opening.

A plastic container is provided that includes a lower supporting base portion; a sidewall portion extending upwardly from the base portion; a neck portion extending upwardly from the sidewall portion; and a closure. The neck portion includes a support flange having an upper and lower surface, threads, a tamper-evident formation, and a dispensing opening at the top of the neck portion. In an embodiment, the weight of the neck portion is 3.0 grams or less; and 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 0.580 inches or less. A preform and method for making a container are also disclosed.
