Embodiment Construction

[0044] see figure 1 , a container 30 constructed in accordance with one embodiment may be cylindrical and extend axially along axis A-A. Container 30 may include a generally cylindrical body 34 including a groove 38 that provides a gripping surface configured to engage between a user's thumb and fingers, for example. The body 34 has an upper portion such as an upwardly extending dome 36 that may narrow along a neck 39 to a container finish 40 . The container finish 40 may have threads 42 configured to engage mating threads on a closure member, such as a conventional cap, that covers a pour opening 43 . The generally cylindrical body 34 may include a lower end defined and closed by the base 32 . Container 30 may be a hot-fill pressure reaction vessel or a cold-fill pressure reaction vessel, and may define an interior space 33 defining an interior volume configured to hold a liquid product (not shown).

[0045] It should be appreciated that the illustrated container 30 is pre...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application No. 61 / 040,067, filed March 27, 2008, the disclosure of which is hereby incorporated by reference in its entirety as set forth. technical field [0003] The present disclosure relates to containers, and more particularly to containers subjected to internal negative pressure after filling, sealing and capping. Background technique [0004] The goal of conventional container design is to create a container body that has a desired and predictable shape after filling and at the point of sale. For example, it is often desirable to manufacture containers that maintain a generally cylindrical body or circular cross-section. However, in some cases, the container is susceptible to internal negative pressure (relative to ambient pressure), which leads to deformation and loss of rigidity and stability of the container, and to an overall unaesthetic appearance. A varie...
