Abstract
A sealing element for sealing a container includes a cap having a top with an opening therein in combination with a septum. The septum includes an elastomer in direct physical contact with an interior surface of the cap. The septum occludes the opening in the top. There is no layer of adhesive or plastic material between the elastomer and the interior surface of the cap. The cap may be made of plastic or metal. Also provided is a method of directly bonding an elastomer, such as silicone rubber, to a plastic or metal.
Claims21
A sealing element comprising:
- a cap having a top with an opening therein;
- and
- a septum formed separately from said cap and comprising an elastomer, the elastomer having an ionized bonding surface directly bonded to an ionized interior surface of said cap thereby occluding the opening in said top and wherein there is no layer of adhesive or plastic material between said bonding surface and said interior surface.
A sealing element comprising:
- a cap having a top with an opening therein;
- and
- a septum formed separately from said cap and comprising an elastomer, the elastomer having an ionized bonding surface directly bonded to an interior surface of said cap, said interior surface having been wetted with a primer, thereby occluding the opening in said top and wherein there is no layer of adhesive or plastic material between said bonding surface and said interior surface.
A sealing element comprising:
- a cap having a top with an opening therein;
- and
- a septum formed separately from said cap and comprising an elastomer, the elastomer having an ionized bonding surface ionized in ambient atmosphere directly bonded to an interior surface of said cap thereby occluding the opening in said top and wherein there is no layer of adhesive or plastic material between said bonding surface and said interior surface.
A sealable container, comprising:
- a container,
- a cap for releasably attaching to said container wherein a liquid-tight seal is formed when the cap is attached to the container;
- said cap having a top with an opening therein;
- and
- a septum formed separately from said cap and comprising an elastomer, the elastomer having an ionized bonding surface ionized in ambient atmosphere directly bonded to an interior surface of said cap thereby occluding the opening in said top and wherein there is no layer of adhesive or plastic material between said bonding surface and said interior surface.
