A bottle for storing and dispensing contents comprises at least one grip portion for improving a user's grip on the bottle. The grip portion is situated on the side of the bottle and extends at least partially along the height of the bottle and comprises a recessed grip panel formed in the side of the bottle adapted to receive the user's fingers and the grip panel is tapered at an angle with respect to the vertical direction. Preferably, the back of the bottle is thinner than the front so that a user can grip the bottle from the back. Preferably, there are a plurality of ribs inclined at a first angle with respect to the horizontal direction and a plurality of cross-hatch ribs inclined at a second angle, the second angle differing from the first at approximately ninety degrees and the ribs forming a lattice arrangement. Preferably, the bottle further comprises a plurality of ridges, situated on the side wall of the bottle for providing strength and rigidity to the bottle. The ridge is a depression across a part of the height of the bottle, has an underside, and extends at least partially along the side wall and comprises a lower portion that extends from the side wall toward the center axis of the bottle so that the contents beneath or on the underside of the ridge can be reached with a utensil.

Bottle with integrated grip portion

Container

A mold assembly for making a polymeric container that is shaped to exhibit superior characteristics of light weighting, stability against toppling and resistance to stress cracking includes a conventional cylindrical body portion having a longitudinal axis and a circumferential sidewall and a novel bottom portion. The bottom portion includes a central pushup area of uniformity that is substantially uniform within a spatial rotation about the longitudinal axis. The area of uniformity has a radius R,. The bottom also includes a plurality of support feet that surround and protrude downwardly from the pushup area. Each of the support feet have a bottom support surface with an inner point of contact and an outer point of contact. The outer points of contact together define an outer contact radius R,. The bottom portion as a whole has a radius of maximum width R,. A plurality of ribs are positioned in valleys between the support feet. Each of these ribs is positioned between and helps define two of the support feet. At least one of the ribs has a localized radius of curvature R,that intersects an arc connecting inner points of contact of two adjacent support feet. Advantageously, the radius of uniformity is within the range of about 16% to about 26% of R,; and R,is within the range of about 70% to about 10% of R,.

Footed container and base therefor

A bottle for storing and dispensing contents comprises a grip portion for improving a user's grip on the bottle. The grip portion is situated on a side of the bottle and extends at least partially along the height of the bottle. The grip portion comprises a recessed panel having a concave shape, formed in the first side of the bottle and adapted to receive the user's fingers. In addition, the grip portion further comprises a grip panel situated on the recessed panel and comprising a plurality of ribs projecting radially outward from the recessed panel. The ribs are oriented substantially vertically to improve the vertical strength of the bottle in the area of the grip portion and spaced-apart so as to form depressions therebetween to receive the user's fingers.
