Abstract
The present invention relates to a lid structure (200) for a container (100), the lid structure comprising: a first lid member (210), and a second lid member (220), the first lid member connected to the second lid member to form a gas tight cavity (230) between the first lid member and the second lid member, the gas tight cavity substantially filled with an inert atmosphere: wherein the first lid member comprises at least one piercing structure (240) configured to be operable by the user to pierce the second lid member and release the inert atmosphere from the gas tight cavity. The present invention further relates to a kit of parts comprising a lid structure and a container and a method (600) of producing a lid structure.
Claims22
A lid structure for a container, said lid structure comprising:
- a first lid member, and
- a second lid member,
- said first lid member connected to said second lid member to form a gas tight cavity between said first lid member and said second lid member,
- said gas tight cavity substantially filled with an inert atmosphere;
- wherein said first lid member comprises at least one piercing structure configured to be operable by the user to pierce said second lid member and release said inert atmosphere from said gas tight cavity.
A kit of parts, said kit of parts comprising:
- a lid structure comprising:
- a first lid member;
- and
- a second lid member;
- said first lid member connected to said second lid member to form a gas tight cavity between said first lid member and said second lid member,
- said gas tight cavity substantially filled with an inert atmosphere,
- wherein said first lid member comprises at least one piercing structure configured to be operable by the user to pierce said second lid member and release said inert atmosphere from said gas tight cavity;
- and
- a container, wherein said lid structure is sized to form a substantially gas tight fit with said container.
A method of producing a lid structure having a first lid member, and a second lid member, said first lid member connected to said second lid member to form a gas tight cavity between said first lid member and said second lid member, said gas tight cavity substantially filled with an inert atmosphere, wherein said first lid member comprises at least one piercing structure configured to be operable by the user to pierce said second lid member and release said inert atmosphere from said gas tight cavity, said method comprising:
- providing said first lid member,
- providing said second lid member, and
- connecting said first lid member to said second lid member to form a gas tight cavity whilst encapsulating an inert atmosphere within said gas tight cavity.
