The invention herein provides a bottle for carrying a fluid or a semifluid, the bottle including: a mouth, a top section, a body, a bottom section, and a base each located sequentially on a y-axis; the body of the bottle comprising a plurality of planar walls, each wall having the same height and width and located perpendicular to the plane of the base on an x-axis, and a cross section of the body being a polygon selected from: triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon, and dodecagon; and a closure having a cross section of a circle or a polygon, and the closure reversibly attachable to the mouth to close the bottle and removable from the mouth to open the bottle. Further, the invention describes methods to obtain purified water using a filtration and purification device.

A container is provided and includes a top wall, a bottom wall, and a plurality of sidewalls defining a plurality of side corners. Each of the side corners includes a top corner. At least one of the top corners has a plurality of spherical polygons including at least a first spherical polygon having a first radius of curvature contiguous with a second spherical polygon having a second radius of curvature.

A bottle split into two parts internally, is disclosed. Each side of the bottle has a different viscous fluid. Turning a rotatable switch on the exterior turns a corkscrew within the bottle, causing a plunger to move transverse to the direction of rotation due to its threaded engagement with the corkscrew. This, in turn, causes the two viscous fluids to exit out of an exit portal side by side simultaneously.

A multiple-chamber container that is extrusion blow molded with a single neck finish and a method to trim the single neck finish is provided. The physical appearance of the multiple-chamber container before the trimming process differs from the multiple-chamber container after the trimming process. The multiple-chamber container includes multiple openings that are configured to engage with a single cap after the trimming process to create a seal. The multiple-chamber container may contain different materials, such as liquids, gel-like substances, granular materials, food, etc. that are not permitted to flow from one chamber to the other chamber when the cap is engaged with the chamber openings.

A stackable liquid vessel may be able to receive, store, and dispense various liquids or fluids, such as beverages, cooking oil or vinegar, motor oil, and/or other appropriate materials or substances. Each stackable liquid vessel may be able to at least partially couple to at least one other stackable liquid vessel. An arrangement of stackable liquid vessels may utilize perforated slipsheets to reduce material usage when packing, shipping, storing, and/or displaying multiple stackable liquid vessels (e.g., a pallet of stackable vessels).

A volume expansion feature for a fluid reservoir is provided, the volume expansion feature comprising a central recess, a plurality of channels extending from the central recess, where the central recess and the channels are positioned at least in part in a recessed surface profile. The recessed surface profile is reversibly moveable from a first inwardly directed configuration, to a second outwardly directed configuration. The central recess and the channels are configured to impart an inward bias to maintain the recessed surface profile in the first inwardly directed configuration under standard loading of the fluid reservoir. Upon increased pressure within the fluid reservoir, the recessed surface profile extends to the second outwardly directed configuration, thereby increasing the volume of the fluid reservoir.

A multiple-chamber container that is extrusion blow molded with a single neck finish and a method to trim the single neck finish is provided. The physical appearance of the multiple-chamber container before the trimming process differs from the multiple-chamber container after the trimming process. The multiple-chamber container includes multiple openings that are configured to engage with a single cap after the trimming process to create a seal. The multiple-chamber container may contain different materials, such as liquids, gel-like substances, granular materials, food, etc. that are not permitted to flow from one chamber to the other chamber when the cap is engaged with the chamber openings.

A bottle for dispensing fuel additives into a capless filler system, the bottle configured with an elongated smooth neck designed for insertion into a capless filler opening to actuate and displace one or more flapper seals when emptying the fuel additives into the capless filler. The bottle is sealed with a cap with a first set of screw threads that engages the neck at a top portion with a second set of screw threads on an interior surface of the top portion of the neck. The length of the smooth elongated neck is at least half the length of a wider storage portion of the bottle. The cap can be a child proof cap. The bottle can be made of plastic that is clear or opaque.

In a container formed of resin in which a concave portion is provided adjacent a vertical center portion of a body portion, the concave portion includes a bottom face, an upper inclined face continuous from an upper side of the bottom face and a lower inclined face continuous from a lower side of the bottom face, and the upper inclined face and the lower inclined face are inclined such that these upper and lower inclined faces are located closer to each other toward the bottom face side, inclination of the lower inclined face is set smaller than inclination of the upper inclined face, and there is provided a vertical groove extending from the bottom face to the lower inclined face.

The present invention relates to systems, methods, and apparatuses for the management, distribution, dispensing, and administration of consumer products, including over-the-counter and prescription medications through use of a product container labeling system and an optional integrated computer-based or online management system. In certain aspects, the invention relates to a product container comprising a hollow body, a child-resistant cap, and a specialized information label affixed to the hollow body.
