Abstract
A container can feature one or more venting regions that can be sealed when the container is in a first operational state and that can provide fluid communication between an interior volume of the container and an environment external to the container when the container is in a second operational state.
Claims25
A container comprising:
- a base defining a first portion and a second portion;
- a lid defining a first portion and a second portion, the lid configured to be coupled with the base in removable engagement so as to cooperate with the base to define an interior volume of the container,
- wherein the first portion of the lid and the first portion of the base are configured to interact to form a substantially liquid-tight seal when a difference in pressure between the interior volume of the container and an environment outside of the container is at or below a threshold value,
- wherein the lid is configured to move away from the base and thereby open a vent for channeling gas from the interior volume of the container to an environment outside of the container when pressure generated within the interior volume of the container is such that a difference in pressure between the interior volume of the container and an environment outside of the container is above the threshold value, and
- wherein the second portion of the lid is configured to interact with the second portion of the base to prevent additional movement of the lid away from the base and thereby maintain the lid and the base in a coupled configuration as additional pressure is generated within the container.
2 more elements
A container comprising:
- a base defining a first surface and a second surface;
- a lid configured to couple with the base and to cooperate therewith to define an interior volume of the container, the lid defining a first surface configured to cooperate with the first surface of the base to form a seal, the lid further defining a second surface configured to cooperate with the second surface of the base to prevent the lid from separating from the base due to pressure generation from within the container;
- and
- one or more vent regions interrupting one or more of the second surface of the base and the second surface of the lid so as to provide a flow channel, wherein the flow channel is configured to provide fluid communication between the interior volume of the container and an exterior of the container when the second surface of the lid cooperates with the second surface of the base to prevent the lid from separating from the base.
1 more element
A container comprising:
- a base including a bottom surface and a sidewall extending from the bottom surface, wherein the sidewall includes a connection region spaced from the bottom surface;
- a removable lid configured to engage the connection region of the base in either a first engagement configuration or a second engagement configuration, wherein the lid is configured to remain coupled with the base in each of the first and second engagement configurations;
- and
- a vent structure configured to define an open space between the lid and the connection region of the base in each of the first and second engagement configurations,
- wherein the lid and the base cooperate to define an interior volume of the container, wherein the lid is configured to transition from the first engagement configuration to the second engagement configuration due to an increase in pressure generated from within the container, and wherein fluid communication between the interior volume of the container and an environment surrounding the container via the vent structure is substantially prevented in the first engagement configuration and is permitted in the second engagement configuration.
