Abstract
The present invention relates to containers and methods suitable for uses such as liquid hot-fill processes. More specifically the invention relates a containers having gas permeable vents with an integral sealing means that is externally activatable by non-mechanical means to effect hermetic sealing of the containers after filling.
Claims23
A method for hot-filling and sealing a container comprising the steps of:
- i. providing a container comprising:
- a container body formed by a container wall defining an interior space and an exterior environment;
- wherein the container body comprises a closable opening, a container closure mated to the closable opening and a gas permeable vent component, comprising a porous material providing gaseous communication between the interior space of the container body and the exterior environment, wherein the vent component further comprises a vent component sealing composition and an energy absorbing layer that is externally activatable by an electromagnetic induction source to effect hermetic sealing;
- ii. filling the container with hot liquid;
- iii. allowing the hot liquid to cool;
- and
- iv. externally activating the energy absorbing layer with the electromagnetic induction source to effect hermetic sealing.
A method for hot-filling and sealing a container comprising the steps of:
- i. providing a container comprising:
- a container body formed by a container wall defining an interior space and an exterior environment;
- wherein the container body comprises a threaded closable opening, a threaded container cap having interior top surface and interior annular surface wherein the threaded container cap is mated to the closable opening;
- and a gas permeable vent in the form of a ring sized and positioned within the threaded container cap such that it is in contact with the interior top surface and interior annular surface of the container cap, wherein the gas permeable vent comprises a porous material and a vent sealing composition and an energy absorbing layer that is externally activatable by an electromagnetic induction source to effect hermetic sealing;
- ii. filling the container with hot liquid;
- iii. allowing the hot liquid to cool;
- and
- iv. externally activating the energy absorbing layer with the electromagnetic induction source to effect hermetic sealing.

- wherein the vent component further comprises a vent component sealing composition and an energy absorbing material in the form of particles dispersed throughout the sealing composition, such that the sealing composition is externally activatable by an electromagnetic induction source to effect hermetic sealing.
- ii. filling the container with hot liquid;
- iii. allowing the hot liquid to cool;
- and
- iv. externally activating the energy absorbing material with the electromagnetic induction source to effect hermetic sealing.
