A synthetic resin container, the container including: a parting line; and a plurality of reduced pressure absorbing panels each formed as a groove extending in the vertical direction while twisting in the circumferential direction, the reduced pressure absorbing panels being disposed in the trunk, in which: when the parting line passes through an upper part of a first reduced pressure absorbing panel and through a lower part of a second reduced pressure absorbing panel, the first reduced pressure absorbing panel is shallower in depth at the upper part thereof than at a central part thereof in the vertical direction, and the second reduced pressure absorbing panel is shallower in depth at the lower part thereof than at a central part thereof in the vertical direction.

The invention relates to a plastic recipient comprising a panel with at least one radius of curvature greater than 100 mm, where the panel has reinforcing means. The reinforcing means includes a peripheral slot defining a reinforcing contour and a plurality of inner slots arranged inside the reinforcing contour. Each inner slot has two ends, where each end opens out into the peripheral slot, or at least one end opens out into another inner slot.

A polymeric container including a finish defining an opening. A base is configured to support the container upright. A grip area is between the opening and the base. A plurality of grip panels are at the grip area. Each one of the grip panels has a depth, a height, and a width. The depth is at least 17% of the height, and the depth is at least 10% of the width.

A plastic container has a base portion adapted for vacuum absorption, the container including a base and a body extending up from the base along a central axis to a finish portion defining a mouth. The base includes an outside wall, a chime connecting the outside wall to an annular contact ring, an inside wall extending upward from the contact ring to a hinge, and a diaphragm connected to the hinge. The diaphragm can move between first and second positions in response to pressure change within the container. The diaphragm includes a central region and a flexible wall having a curved profile in cross section. The flexible wall curves downward from the hinge to the central region. In some embodiments, the flexible wall is asymmetric and includes a first portion having a curved profile and a second portion having a linear profile. A container wall structure is also disclosed.

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 (100) includes a body (110) having an upper end (104) and a lower end (106). The upper end has an opening formed therethrough. The body defines a plurality of ribs (110) between the upper end and the lower end that are configured to actuate between an expanded state and a compressed state to vary a volume inside the body. A sleeve (500) is positioned at least partially around the body. The sleeve inhibits one or more of the plurality of ribs that are in the compressed state from actuating into the expanded state.

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.

The side wall, extending below a shoulder of the thermoplastic bottle, has a gripping portion formed substantially in the middle of the bottle body and includes a first line and a second line each defined in a vertical symmetry plane. The second line has a second point at minimal distance ds2 between the side wall and the central axis, while the first line has a first point at minimal distance dsl between the first line and the central axis. For these particular points in the gripping portion: .Math.ds2<ds1.Math.hs1<hs2 A thick portion is provided at and above the second point.

The present invention relates to a bottle having a cylindrical shape with a bottom and formed of a synthetic resin material. In the bottle, a bottom portion includes a bottom wall portion, and a cylindrical heel portion. A plurality of recessed portions are provided in the bottom portion at equal intervals in a circumferential direction. A bottom surface of each of the plurality of recessed portions has a rectangular shape extending in the radial direction when viewed from below. When an interval in the circumferential direction between upper end portions located at the heel portion, among bottom surfaces of recessed portions adjacent to each other in the circumferential direction of the plurality of recessed potions, is defined as A, and a size in the circumferential direction of the upper end portions of the bottom surfaces of the recessed portions is defined as B, 1.0<A/B<3.2 is satisfied.
