Abstract

A sealing cover includes an upper cover member which is impervious to bacteria and moisture, and is attached to an annular ring member, also impervious to bacteria and moisture. The upper cover member and annular ring member are attached to each other by means of an adhesive which, when the upper cover member is detached from the annular ring member, leaves substantially no visible indication of adhesive residue on the annular ring member, while losing its adhering properties. Another layer of adhesive is provided on the bottom of the annular ring for attaching the sealing cover to the rim of the opening of a container such as an I.V. container, in a non-removable manner such that the upper cover member can be removed without removing the annular ring member from the rim of the container to which it is attached.

Claims5

Dependent claims

A sealing cover strip for covering of a membrane of a container in a sterile manner and as a visual indication of removal of the cover strip from the membrane and loss of sterility thereof, with said container having an opening with a rim, and wherein said membrane is positioned within said opening to close said opening, with said cover strip comprising:

an upper strip member which is substantially impermeable to moisture and bacteria;
a first adhesive layer, in a ring shape, on the bottom of said strip member, for adhering said strip member to an annular ring member strip made of a material substantially impervious to moisture and bacteria;
a second adhesive layer on the bottom of said annular ring member strip for adhering said annular ring member strip to the rim of said container for sealingly covering the membrane of the container in a sterile manner;
and
said first adhesive layer being adapted wherein upon separation of said upper cover member from said annular ring member, the first adhesive layer loses substantially all adhesive properties on said annular ring member, and wherein said second adhesive is adapted such that when said upper cover member is removed, said annular ring member is held securely on the rim of any container to which said annular ring member has been attached, to thereby provide visual indication of removal of the cover strip from the membrane and loss of sterility thereof, wherein said first adhesive layer is UV cured varnish and said second adhesive layer is pressure sensitive adhesive.

A sterile sealed container comprising an opening with a rim, a membrane positioned within said opening to effect a closing of the container with a sterile seal, and a protective sealing cover strip for covering the membrane of the container in a sterile manner, with said cover strip comprising visual indicating means of removal of the cover strip from the membrane and loss of sterility thereof, with said cover strip comprising:

an upper strip member which is substantially impermeable to moisture and bacteria;
a first adhesive layer, in a ring shape, on the bottom of said upper strip member, for adhering said upper strip member to an annular ring member strip comprised of a material substantially impervious to moisture and bacteria:
a second adhesive layer on the bottom of said annular ring member strip for adhering said annular ring member strip to the rim of said container for sealingly covering the membrane of the container in a sterile manner;
wherein said first adhesive layer is adapted such that upon separation of said upper strip member from said annular ring member strip, the first adhesive layer loses substantially all adhesive properties on said annular ring member strip, and wherein said second adhesive layer is adapted such that when said upper strip member is removed, said annular ring member strip is held securely on the rim of the container to which said annular ring member has been attached, to thereby provide visual indication of removal of the cover strip from the membrane and loss of sterility thereof.
