Multi-compartment containers including multi-compartment cans, canisters, boxes and bags and methods for using the same are disclosed. Multi-compartment containers that provide access to one portion of the contents until depleted while maintaining a seal and thus protecting the freshness or potency, of the contents on another portion allows products to be packaged and sold in a way that maintains freshness and potency longer. Each compartment of the multi-compartment containers can be configured to have either a single-use or re-sealable seal.

A hair treatment apparatus includes a base and a sidewall in direct contact with and extending from the base. The base and sidewall define a cavity configured for receiving a liquid. The hair treatment apparatus further includes a lid coupled to the sidewall opposite to the base, the lid defining an adjustable aperture configured for receiving a portion of hair for treatment in the liquid. The lid includes a first ring, a plurality of plates, and a second ring. The first ring is configured to releasably engage the sidewall and define a central axis. The plurality of plates extend from the first ring toward an aperture, each of the plurality of plates includes a pin. The second ring defines a plurality of slots to receive the pins. Rotation of the second ring causes the plurality of plates to extend toward the longitudinal axis to reduce the diameter of the aperture.

A can lid is provided for excellence in an explosion-proof function and a suitability for a hammering inspection. A buckling-inducing section that is easily deformed angularly is formed on a plurality of sites in a circumferential portion of a panel section. A score line intersects with a virtual line passing through a center of the panel section and a center of the buckling-inducing section. End portions of the score line are situated closer to the center of the panel section than a virtual boundary line extending perpendicular to the virtual line. A circular depression is formed at the center of the panel section. A slant wall section is formed between the buckling-inducing section and an inner side wall, and the slant wall section is joined to the inner side wall through a curved portion.

A safety lid for bottles, comprising a pouring element that can be attached to the neck of a bottle, a closure cap attached to the pouring element through a rear hinge, a flexible protrusion, located in its part closest to the pouring element, which contacts the pouring element in the open position, and two lateral flanges. The lid comprises a first opening indicator element located in the space delimited between both flanges, consisting of a flange comprising a first sector attached to the pouring element, a second sector attached to the closure cap, and a breakable central sector that allows a break and separation of the flange when a first opening of the lid occurs and a subsequent torsion deformation of the first sector and the second sector of that flange.
