A bottle includes a finish defining a bottle opening, a bell carrying the finish, a base, a central axis extending from the finish to the base, a sidewall extending between the bell and the base, and at least two grooves that circumferentially extend around the sidewall and spaced apart relative to the central axis, the grooves being circumferentially offset from one another.

A bottle may have varying depth ribs to achieve a balance of strength and rigidity while maintaining hoop strength. The varying depth ribs may smoothly transition around the circumference of the bottle from a flattened and/or shallow depth rib portion to a deep rib portion. A collection of flattened and/or shallow depth ribs act as recessed columns in the body of the bottle to resist bending, leaning, crumbling, and/or stretching. The deep rib portions provide hoop strength and make the bottle body more rigid and/or stiffer when gripped by a user. A balance may be achieved between of flattened and/or shallow depth ribs and deep ribs to attain a desired resistance to bending, leaning, and/or stretching while maintaining stiffness in a lightweight bottle.

A container including a thermoformed tub made of a plastics material and including at least one dosing unit located in the tub interior, which dosing unit includes at least one active ingredient and a water-soluble casing for the active ingredient, the tub having a base and a tub wall that extends from the base. The tub wall has a plurality of projections that are oriented from a datum plane of the tub wall towards the tub interior, a distance between adjacent projections being less than a length and less than a width of the dosing unit. Preferably, the projections have a plurality of parallel ridges.

Preferably, the projections have a plurality of parallel ridges.

The container is used for receiving liquids and is formed substantially from a thermoplastic material. A container wall is provided at least in certain regions with a rib-like structure. The container wall has an oval profile in a horizontal cross-sectional area. The container is provided with two mutually opposite curved longitudinal sides and two mutually opposite curved transverse sides. In the region of at least one of the longitudinal sides, the rib-like structure is configured in such a way that it has, at least in certain regions, a reinforcing rib of closed encircling shape.

A container may comprise a tubular body having a rounded sidewall extending between a closed end defining a base portion and an opposite open end surrounded by a rim portion, and one or more sets of grooves defined within the vertical portion of the rounded sidewall. The base portion is configured to support the container in an upright orientation relative to a support surface and wherein the base portion defines a support ring having an at least substantially rounded perimeter. The rounded sidewall comprises a curved base transition region and a vertical portion extending between the perimeter of the base portion and the rim portion along a central axis. Each of the grooves comprises a length and a width, wherein the length is longer than the width. The grooves extend between the base portion and the rim portion along the length.

A container having enhanced wall integrity and a rotational element is provided that includes a sidewall having polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the interior valleys of the second container in order to orient the containers as they are stacked.
