Abstract
An apparatus and a process for forming a protective barrier seal along a “ring of concern” of a transfer container used with double door systems is provided. A protective substrate is supplied between a “ring of concern” and a safety cover in which an adhesive layer of the substrate engages the “ring of concern”. A compressive foam strip along an opposite side of the substrate engages a safety cover such that a compressive force is maintained between the “ring of concern” and the adhesive layer of the substrate.
Claims6
A process of preventing the spread of contamination from a transfer container used with a double door system comprising:
- removing a container from a double door apparatus;
- applying to an upper surface of the container a substrate, an adhesive applied to a first surface of said substrate and a foam strip applied to a second surface of said substrate, said foam strip conforming generally to the size and shape of a gasket carried by the container;
- applying said substrate to the upper container surface thereby positioning an adhesive side of said substrate to said gasket and said container lid of the container;
- and,
- engaging said container lid with a safety cover, said safety cover compressing said foam strip thereby maintaining a pressure engagement of said paper substrate and said adhesive layer against the gasket and the portion of said container surrounding said gasket.
A sealed double door transfer container comprising:
- a lid, a bottom, and a sidewall defining a volume therein;
- a gasket, positioned within a groove associated with an opening to said container;
- a container lid positioned on top of said container and engaging at least a portion of said gasket;
- a substrate applied to said opening of said container, said substrate having an adhesive layer engaging the container lid and the gasket, said substrate further defining a foam strip on an upper surface of said substrate, said foam strip conforming generally to the shape and dimensions of said gasket;
- and,
- a safety cover applied over said opening of said container, said safety cover compressing said foam strip in a region opposite said gasket, thereby providing a compressive force to said adhesive substrate in proximity to said gasket.
A containment seal for a transfer container used with a double door transfer apparatus comprising:
- a substantially flat substrate layer having dimensions adapted for a lid of a transfer container;
- an adhesive layer applied to at least a portion of a lower surface of said substrate;
- and,
- a compressible foam layer applied to an upper surface of said substrate, said foam layer corresponding to the shape and dimensions of a gasket carried by an upper surface of a transfer container, said compressible foam layer further adapted for engaging an inner surface of a safety cover such that when said safety cover is applied to said transfer container, said compressible foam layer is compressed, thereby maintaining pressure between said adhesive layer and a gasket carried on a transfer container lid.
