The outer cup includes an upper lip with a threaded surface configured to engage with a mating threaded surface of a lid. The inner cup includes an engaging lip configured to engage with a lower inner lip and configured to form a seal between the inner cup and the lid, as well as a flange located below the engaging lip that extends outward from a periphery of the inner cup. The lid includes an outer wall with a lower outer lip comprising the mating threaded surface, the mating threaded surface is configured to engage with a threaded surface. The cap includes a mating engagement feature configured to engage with an inner wall engagement feature.

A method for the storage and delivery of a stable form of lactase to an infant as a dietary supplement. The lactase is stored first as a dry powder contained in a push cap. The push cap is then fixed to a bottle containing a plurality of anhydrous neutral oils. Once the push cap is fixed on the bottle, the push cap is pressed, releasing the lactase powder into the neutral oil. The bottle is then agitated to produce a mixture of lactase in the neutral oils. Finally, a dropper is used to deliver the stable lactase-oil mixture to the infant in need thereof.

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 vessel closure (1, 21, 41, 61) includes a sealing element (3, 23, 43, 63). The sealing element (3, 23, 43, 63) includes a polymer composition. The polymer composition includes a polyalphaolefin with kinematic viscosity, determined according to ASTM D445 / ISO 3104, of at least 4 cSt, at a temperature of 100° C., and/or a dropping point, determined according to ASTM 5950, of at most -10° C., and up to 95% by weight of a second polyolefin.

What is proposed is a closure unit consisting of a glass container (50) with external, circumferentially offset threaded elements (54, 55) on a container neck (52) of the glass container, and a closure cover made of sheet metal, wherein the closure cover (1, 2) has an encircling plastics layer (30; 30h, 30v) on the inside of the cover. The closure cover is pressed onto the container neck (52) and can be opened with a rotational movement via the threaded elements (54, 55) and a vertical section (30v) of the plastics layer. The container neck (52) has a horizontal end surface (52a) on which a horizontal section (30h) of the plastics layer rests under pressure in a sealing manner. A central region (11) of the closure cover passes with an adjoining, circumferentially oriented transition zone (11a, 11b, 11c) into an axially downwardly projecting skirt section (12) which ends in a roll-up region (21a, 21; 22). The plastics layer (30; 30h, 30v) is arranged on the inside of the cover in a manner adhering to the transition zone (11a, 11b, 11c) and the skirt section (12). An axial extent (h.sub.0) of the skirt section (12) and a radial dimension (b52) of the horizontally oriented end surface (52a) of the container neck (52) form a first ratio (v.sub.1) which is smaller than three.

A closure for a beverage container has a body having an attachment interface to engage to a top of a beverage container, a sealed, elongated enclosure attached to an underside of the body, and a single access element adapted to selectively open and close either a first opening passing through the body into the sealed, elongated enclosure or a second opening passing through the body directly to an inner volume of the beverage container.

An apparatus includes an exterior portion, an interior portion, a first top, and a second top. The exterior portion includes an exterior wall, an exterior top end coupled to the exterior wall, and an exterior bottom closed end coupled to the exterior wall. The interior portion nests within the exterior portion and includes an interior wall having a geometry smaller than the exterior portion, an interior bottom closed end coupled to the interior wall, and an interior top end coupled to the interior wall opposite the interior bottom closed end. The first top closes the interior top end to form an interior space within the interior portion. The first top includes a first opening. The second top includes a second opening. The second top engages with the exterior bottom end in a stored position and engages with the exterior top end in a containing position.

A container for storing perishable contents comprising an inner storage chamber defining top and bottom ends and comprising a floor at the bottom end thereof and an inner wall extending from the floor towards an opening at the top end thereof. The floor and the inner wall defining a storage cavity therebetween. An outer wall covers the inner wall and downwardly extends from a junction therewith at or near the top end of the storage chamber towards a bottom edge thereof at or near the bottom end of the storage chamber. The outer wall and the inner wall are spaced apart to define an air channel therebetween for receiving air. The bottom edge of the outer wall and the floor of the storage chamber define an opening therebetween leading to the air channel. The air channel provides for allowing a layer of air between the outer wall and inner wall to act as insulation for the perishable contents.
