Tamperproof pouch label

Claim 2

A pouch for packaging viable perishable materials comprising, in combination, a. a section of tubular transparent plastic film flattened to define two substantially planar parallel side walls, b. a first linear seal extending transversely of the side walls and sealing them to each other interiorly of the pouch, c. a second linear seal extending substantially parallel to the first seal transversely of the side walls and sealing them to each other interiorly of the pouch at one end of the section to form a bottom closure and to define a sealed label compartment intermediate the bottom closure and the unclosed end of the section between said first linear seal and said second linear seal and an open ended fillable compartment contiguous to said sealed label compartment and d. a label disposed in the sealed label compartment, said label having a pressure sensitive surface to produce indicia discernible through the film contiguous thereto in response to marking pressures applied thereto through the film exteriorly of the pouch.

Claim 3

A pouch according to claim 1 having a third linear seal extending transversely across the side walls and sealing them to each other interiorly of the pouch at an end of the section to define a substantially closed fillable compartment between said first and said third linear seals and at least one selectably sealable aperture communicating from the exterior of said fillable compartment with the interior thereof.

Claim 4

A pouch according to claim 2 having a fourth linear seal extending transversely across the side walls and sealing them to each other interiorly of the pouch at an end of the section to define a pouch fillable compartment between said second and said fourth linear seals and at least one selectably sealable aperture communicating from the exterior of said fillable compartment with the interior thereof.

Claim 5

A pouch for packaging viable perishable materials comprising, in combination, a. a section of tubular transparent plastic film flattened to define two substantially planar parallel side walls, b. a first linear seal extending transversely across the side wall edges at one end of the section and sealing them to each other to define an end closure, c. a second linear seal extending substantially parallel to the first seal transversely across the side walls and sealing them to each other interiorly of the pouch to define a sealed label compartment between the first linear seal defining the end closure and the second linear seal and an open ended fillable compartment contiguous to said sealed label compartment and d. a label disposed in the sealed label compartment, said label having a pressure seNsitive surface to produce indicia discernible through the film contiguous thereto in response to marking pressures applied thereto through the film exteriorly of the pouch.

Claim 6

A pouch for packaging viable perishable materials comprising, in combination, a. a section of tubular transparent plastic film flattened to define two substantially planar parallel side walls, b. a first linear seal extending transversely across the side wall edges at one end of the section and sealing them to each other to define an end closure, c. a second linear seal extending substantially parallel to the first seal transversely across the side walls and sealing them to each other interiorly of the pouch to define a sealed label compartment between the first linear seal defining the end closure and the second linear seal and an open ended fillable compartment contiguous to said sealed label compartment and d. a label disposed in the sealed label compartment, said label having a pressure seNsitive surface to produce indicia discernible through the film contiguous thereto in response to marking pressures applied thereto through the film exteriorly of the pouch.

Claim 7

A pouch according to claim 4 having a third linear seal extending transversely across the side wall edges at the end of the section opposite the end closed by the first linear seal, sealing them to each other to define another end closure and at least one selectably sealable filling aperture communicating from the exterior of the pouch to the pouch interior compartment between the second and third linear seals.

Claim 8

A pouch according to claim 4 wherein the label pressure sensitive surface comprises surface encapsulated indelible fluid.

Claim 9

A pouch for packaging, freezing, storing, transporting and thawing viable perishable materials frozen and stored at cryogenic temperatures in the order of about that of liquid nitrogen comprising, in combination, a. a section of tubular transparent plastic film flattened to define two substantially planar parallel side walls, b. a first linear seal extending transversely across the side wall edges at one end of the section and sealing them to each other to define an end closure, c. a second linear seal extending substantially parallel to the first seal transversely across the side walls and sealing them to each other interiorly of the pouch to define a sealed label compartment between the end closure and the remainder of the pouch, d. a third linear seal extending substantially parallel to the second seal transversely across the side wall edges at the end of the section opposite the end sealed by the first linear seal to define a fillable compartment between the second seal and the third seal, e. at least one selectably sealable aperture communicating from the exterior of the pouch to the interior of said fillable compartment and f. a label disposed in the sealed label compartment, said label having a pressure sensitive surface to produce indicia discernible through the film contiguous thereto in response to marking pressures applied thereto through the film exteriorly of the pouch.

Claim 10

A pouch for packaging, freezing, storing, transporting and thawing viable perishable materials frozen and stored at cryogenic temperatures in the order of about that of liquid nitrogen comprising, in combination, a. a section of tubular transparent plastic film flattened to define two substantially planar parallel side walls, b. a first linear seal extending transversely across the side wall edges at one end of the section and sealing them to each other to define an end closure, c. a second linear seal extending substantially parallel to the first seal transversely across the side walls and sealing them to each other interiorly of the pouch to define a sealed label compartment between the end closure and the remainder of the pouch, d. a third linear seal extending substantially parallel to the second seal transversely across the side wall edges at the end of the section opposite the end sealed by the first linear seal to define a fillable compartment between the second seal and the third seal, e. at least one selectably sealable aperture communicating from the exterior of the pouch to the interior of said fillable compartment and f. a label disposed in the sealed label compartment, said label having a pressure sensitive surface to produce indicia discernible through the film contiguous thereto in response to marking pressures applied thereto through the film exteriorly of the pouch.
