Self-sealing specimen pouch assembly

Claim 2

A specimen pouch assembly, comprising: first, second, and third plies of material, said plies being juxtaposed and at least partially coextensive, said first and second plies being joined to each other at confronting peripheral portions thereof to define a specimen-receiving enclosure therebetween, said second ply defining an access opening communicating with said enclosure for placing an associated specimen therein, said third ply being joined to said second ply to define an identification-receiving pocket therebetween, said third ply having a length less than said second ply so that a free edge of said third ply defines, with said second ply, an opening into said pocket, said access opening defined by said second ply being positioned between said pocket opening and an associated end of said pouch assembly, and self-sealing means for closing said access opening by folding and sealing an end portion of said pouch assembly to close said access opening, said folded end portion extending to overlap said free edge of said third ply and partially overlie said third ply and thereby close said opening into said pocket to retain associated identification means therein.

Claim 3

A specimen pouch assembly in accordance with claim 1, wherein said first and second plies of material are joined to each other substantially throughout the length of the confronting peripheral portions thereof, said access opening being provided by an access slit in said second ply spaced from the associated end of said pouch assembly.

Claim 4

A specimen pouch assembly in accordance with claim 1, wherein said self-sealing means comprises pressure-sensitive adhesive disposed on respective opposite sides of said access opening.

Claim 5

A specimen pouch assembly in accordance with claim 3, wherein said self-sealing means comprises pressure-sensitive adhesive substantially surrounding said access opening to provide a tamper-evident seal upon closing of said opening.

Claim 6

A specimen pouch assembly in accordance with claim 3, including release strip means removably secured to said pressure-sensitive adhesive to maintain said adhesive in a fresh condition prior to use, said release strip means defining a slit substantially coextensive with said access opening to facilitate insertion of a specimen into said pouch assembly prior to removal of said release strip means.

Claim 7

A specimen pouch assembly, comprising: first, second, and third rectangular plies of material, said plies being juxtaposed and at least partially coextensive, said first and second plies being coextensive with each other and joined to each other substantially throughout the length of confronting peripheral portions thereof to define a specimen-receiving enclosure therebetween, said second ply defining a transversely extending access opening spaced from an associated end of said pouch assembly and communicating with said enclosure for placing an associated specimen therein, said third ply being joined to said second ply to define an identification-receiving pocket therebetween, said third ply having a length less than said second ply so that a free edge of said third ply defines, with said second ply, an opening into said pocket, said access opening defined by said second ply being positioned between said pocket opening and an associated end of said pouch assembly, and self-sealing means for closing said access opening by folding and sealing an end portion of said pouch assembly to close said access opening, said self-sealing means comprising pressure-sensitive adhesive disposed on said second ply on respective opposite sides of said access opening to form a tamper-evident seal, said folded end portion extending to overlap said free edge of said third ply and partially overlie said third ply and thereby close said opening into said pocket to retain associated identification means therein.

Claim 8

A specimen pouch assembly, comprising: first, second, and third rectangular plies of material, said plies being juxtaposed and at least partially coextensive, said first and second plies being coextensive with each other and joined to each other substantially throughout the length of confronting peripheral portions thereof to define a specimen-receiving enclosure therebetween, said second ply defining a transversely extending access opening spaced from an associated end of said pouch assembly and communicating with said enclosure for placing an associated specimen therein, said third ply being joined to said second ply to define an identification-receiving pocket therebetween, said third ply having a length less than said second ply so that a free edge of said third ply defines, with said second ply, an opening into said pocket, said access opening defined by said second ply being positioned between said pocket opening and an associated end of said pouch assembly, and self-sealing means for closing said access opening by folding and sealing an end portion of said pouch assembly to close said access opening, said self-sealing means comprising pressure-sensitive adhesive disposed on said second ply on respective opposite sides of said access opening to form a tamper-evident seal, said folded end portion extending to overlap said free edge of said third ply and partially overlie said third ply and thereby close said opening into said pocket to retain associated identification means therein.

Claim 9

A specimen pouch assembly in accordance with claim 6, wherein said self-sealing means comprises pressure-sensitive adhesive on said second ply substantially surrounding said access opening so that said end portion can be folded generally along the extent of said transverse access opening to form a tamper-evidence seal.

Claim 10

A specimen pouch assembly in accordance with claim 6, including release strip means removably secured to said pressure-sensitive adhesive to maintain said adhesive in a fresh condition prior to use, said release strip means defining a slit substantially coextensive with said access opening to facilitate insertion of a specimen into said pouch assembly prior to removal of said release strip means.

Claim 11

A specimen pouch assembly in accordance with claim 6, wherein said first, second, and third plies comprise transparent plastic film material.

Claim 12

A specimen pouch assembly in accordance with claim 6, including means for opening said pouch assembly comprising at least one opening slit formed at the confronting peripheral portions of said first and second plies between said pressure sensitive adhesive and said free edge of said third ply.
