Abstract
A plastic container is provided having a container body and a closed base. The base includes a base body and a plurality of deflection ribs configured to buckle as the base deforms in response to an increase in negative pressure internal to the container.
Claims20
A plastic container configured to absorb negative internal pressure, the plastic container comprising:
- a substantially cylindrical container body defining an upper portion that extends upwardly to a finish, and an opposing lower portion;
- an enclosed base connected to the lower portion of the substantially cylindrical container body, the base comprising:
- a standing member configured to rest on a support surface;
- a substantially centrally disposed hub disposed radially inward from the standing member;
- a base body extending between the standing member and the central hub, the base body including at least one deflection rib configured to buckle in response to a threshold level of negative internal pressure,
- wherein the base body can deform from an as-molded state to a deformed state in response to an increase in negative internal pressure, and further deformation of the base body in response to further increased negative internal pressure causes the rib to buckle, thereby allowing the base body to further deform from the deformed state to a deflected state.
A plastic container configured to deform from an as-molded state in response to negative internal pressure, the plastic container comprising:
- a substantially cylindrical container body;
- and
- a base connected to a bottom portion of the container body, the base including a standing member, a substantially central hub, and a base body extending between the standing member and the hub, wherein the base body includes a deflection rib projecting up from the base body, the rib configured to deflect when the base body deforms in response to an increase in negative internal pressure.
The plastic container configured to deform from an undeformed state to a deflected state, the plastic container comprising:
- a container body;
- and
- a base connected to the container body, the base comprising:
- a standing member;
- a base body extending in from the standing member, the base body including a rib that defines an enclosed perimeter, wherein the rib is configured to deflect in response to deformation of the base from the undeformed state to the deflected state.
