The Improved Salad Dressing Preparation and Storage Container is a food preparation device that allows for conveniently measuring, mixing, and dispensing of homemade vinaigrette salad dressing. The device uses two adjacent, adjoined compartments that are volumetrically proportioned to allow for the recommended ratio of oil and vinegar (acid) to be consistently achieved by filling them with oil and vinegar to the same apparent level. The Improved Salad Dressing Preparation and Storage Container may also be configured for commercial sale pre-filled with the oil and vinegar contents, those kept separated by sealing the adjoined compartments using an adapted seal. The pre-filled container may be designed and marketed for secondary use by consumers for use in making their own vinaigrette salad dressing recipes.

In some embodiments, apparatuses and methods provided herein are useful for dispensing a fluid, such as a thixotropic fluid. In some embodiments, a bottle having a closure cap includes a flip top, a base, and a disk, where the base and disk define a mixing chamber configured to facilitate mixing of any serum or liquid separated from the fluid back therein. In some configurations, the base has a central opening through which the fluid exits and an internal shaft with a non-planar end surface opposite the central opening. In some configurations, the non-planar end surface and the disk define channels between the mixing chamber and the internal shaft. In some embodiments, the disk includes a central opening, a plurality of partial annular openings through a planar surface of the disk, and projections extending into the mixing chamber.

A container lid includes a container top, a lid opening, a closure, a push button, and a lock. The container top may be sized and configured to be attached to a container body. The lid opening may be formed in the container top. The closure may be movably coupled to the container top and may be movable between first and second positions in which the lid opening is, respectively, covered or uncovered. The push button may be configured to selectively retain the closure in the first position, and may be movable between latched and unlatched positions. The lock may be movable between locked and unlocked positions and in the locked position may be configured to inhibit movement of the push button from the latched to the unlatched position.

Disclosed herein is a cap configured to interact with a neck. In some embodiments, the cap comprises an inner wall portion and at least one cutting element projecting radially inwards from the inner wall portion. In some embodiments, the cutting element has a hinge portion connected to the inner wall portion, and a cutting portion extending radially inwards from the hinge portion, wherein a first axial thickness of the hinge portion is between 35 and 80% of a second axial thickness of the cutting portion. Also disclosed herein is an assembly comprising the cap and a spout having a membrane closing a tubular member of the spout.

A cap and neck assembly for closing an upper end of a package (10) is provided. The neck (20) is formed by a tubular member (110) being provided with external threads (22), and an upper tubular portion (120) extending from the tubular member (110) and being releasably attached to a membrane (150) closing an upper end of said upper portion (120). The cap has a lower portion the threads (22) of the neck (20), and an upper portion (33) being provided with at least one cutting element (50) configured to separate the membrane (150) from the neck (20). When the cap (30) is threaded onto the neck (20) to its axial end position for the first time prior to separating the membrane (150) from the neck (20), the axial distance between a cutting edge (54) of the cutting element (50) and the membrane flange (170) is less than 1 mm.
