Plastic container with strapped base
A container may have a base, a sidewall connected to the base, a bell connected to the sidewall, and a finish connected to the bell. The base may have strap ribs to resist deformation of the base. The sidewall may have recessed columns to resist bending, leaning, crumbling, and/or stretching. The strap ribs and recessed columns may vertically line up along a central axis of the container to communicate forces on the container vertically along the container to continuously resist deformation in the base and the sidewall.
1 . A plastic container configured to hold a liquid and resist deformation, the container comprising:
a base including a hemispherical configuration and a plurality of strap ribs extending from a central portion of the base to a circular perimeter, a plurality of load ribs disposed between adjacent strap ribs, and a plurality of feet formed between the strap ribs and the load ribs, the plurality of feet comprising a resting surface of the plastic container;
a sidewall comprising a grip portion extending from the base in a longitudinal direction to a label panel which extends to a shoulder, the grip portion comprising circumferentially positioned grip portion ribs, wherein each grip portion rib includes a deep portion that transitions in the circumferential direction to a shallow portion, and wherein the shallow portions are aligned in the longitudinal direction;
a bell comprising a diameter which decreases as the bell extends from the shoulder to a neck; and
a finish connected to the neck and configured to receive a closure, the neck and finish defining an opening to an interior of the container,
wherein no intervening rib exists between each strap rib of the plurality of strap ribs and the circumferentially positioned grip portion ribs, and
wherein each strap rib of the plurality of strap ribs extends to one of the circumferentially positioned grip portion ribs.
2 . The plastic container of claim 1 , wherein the circumferentially positioned grip portion ribs are angulating ribs.
3 . A plastic container configured to hold a liquid and resist deformation, the container comprising:
a base including a hemispherical configuration and a plurality of strap ribs extending from a central portion of the base to a circular perimeter, a plurality of load ribs disposed between adjacent strap ribs, and a plurality of feet formed between the strap ribs and the load ribs, the plurality of feet comprising a resting surface of the plastic container; and
a sidewall comprising a grip portion extending from the base in a longitudinal direction to a label panel which extends to a shoulder, the grip portion comprising circumferentially positioned angulating grip portion ribs, wherein each grip portion rib includes a deep portion that transitions in the circumferential direction to a shallow portion, and wherein the shallow portions are aligned in the longitudinal direction,
wherein no intervening rib exists between each strap rib of the plurality of strap ribs and the circumferentially positioned grip portion ribs, and
wherein each strap rib of the plurality of strap ribs extends to one of the circumferentially positioned grip portion ribs.
4 . The plastic container of claim 1 , wherein the plurality of strap ribs extends to a height along the base which is greater than a height of the plurality of load ribs.
5 . The plastic container of claim 3 , wherein the plurality of strap ribs extends to a height along the base which is greater than a height of the plurality of load ribs.
6 . The plastic container of claim 1 , wherein each strap rib of the plurality of strap ribs has a depth into the base which is greater than a depth of the plurality of load ribs.
7 . The plastic container of claim 3 , wherein each strap rib of the plurality of strap ribs has a depth into the base which is greater than a depth of the plurality of load ribs.
8 . The plastic container of claim 1 , wherein each strap rib of the plurality of strap ribs is substantially parallel to the resting surface and extends along an upward curved path toward the sidewall of the container, wherein the upward curved path comprises at least a first curve and a second curve, both of the first and second curves having an increasingly positive slope.
9 . The plastic container of claim 3 , wherein each strap rib of the plurality of strap ribs is substantially parallel to the resting surface and extends along an upward curved path toward the sidewall of the container, wherein the upward curved path comprises at least a first curve and a second curve, both of the first and second curves having an increasingly positive slope.
10 . The plastic container of claim 1 , wherein each deep portion has a depth relative to the sidewall of at least 1.5 mm.
11 . The plastic container of claim 1 , wherein each deep portion has a depth relative to the sidewall of at least 1.7 mm.
12 . The plastic container of claim 1 , wherein each deep portion has a depth relative to the sidewall of at least 2.0 mm.
13 . The plastic container of claim 12 , wherein each second depth portion has a depth relative to the sidewall of at least 1.3 mm.
14 . The plastic container of claim 12 , wherein each second depth portion has a depth relative to the sidewall of at least 1.7 mm.
15 . The plastic container of claim 1 , wherein a ratio of the depths of the deep portion to the shallow portion for each rib of the plurality of circumferentially positioned ribs is at least 2:1.
16 . The plastic container of claim 1 , wherein a ratio of the depths of the deep portion to the shallow portion for each rib of the plurality of circumferentially positioned ribs is at least 4:1.
