Containers and Lids and Methods of Forming Containers and Lids

摘要

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element.

1. An insulating device comprising:
a container comprising:
a first inner wall having a first end with a threaded sidewall and an opening extending into an internal reservoir for receiving liquid;a second outer wall forming an outer shell of the container, the second outer wall having a second end configured to support the container on a surface;a sealed vacuum cavity forming an insulated double wall structure between the first inner wall and the second outer wall; a closure adapted to seal the opening of the container, the closure comprising:
an upper portion having a frustoconical surface spaced between a circular top surface and a cylindrical surface, the upper portion further having a handle that is integrally-molded to the frustoconical surface at two diametrically-opposed points, the handle further comprising:
an outer surface, at least a portion of the outer surface having a circular curvature concentric with, and having a radius equal to the cylindrical surface;an inner surface having an overmolded grip;a lower portion comprising:
a sidewall having a threaded area adapted to be received into the threaded sidewall of the first inner wall of the container;a channel extending around a lower area of the sidewall, and configured to retain a gasket,wherein the gasket is configured to compress against a lip structure extending from the first inner wall of the container when the threaded area of the sidewall is received by the threaded sidewall of the first inner wall,wherein the gasket comprises a radially-extending vent structure, andwherein the upper portion and the lower portion form a sealed cavity therebetween.
