Shipping bag for containers of potentially biohazardous liquids

Claim 2

A shipping bag for containers of potentially biohazardous liquids characterized by the ability to absorb such liquid upon rupture of the container and to protect persons handling the bag from contact with such liquid, said bag comprising: (a) first and second outer panels formed of liquid impervious material connected along opposed side edges and one end to define an open top liquid impervious body portion; (b) liquid absorbing means confined within said body portion and comprising a pair of absorbent pads arranged adjacent each of said first and second outer panels; (c) first and second inner panels formed of liquid permeable sheet material made of hydrophobic filaments, wherein said inner panels are confined within said body portion and disposed parallel to said first and second outer panels and respectively connected therewith along said opposed side edges and opposite ends to define an open inner space in communication with said open top and separating said liquid absorbing means from said inner space; and (d) closure means at said open top to sealingly close said inner space and retain any liquids within said body portion to protect persons handling the shipping bag from contact with potentially biohazardous liquid.

Claim 3

The shipping bag according to claim 1 wherein said first and second outer panels are comprised of a polyolefin film.

Claim 4

The shipping bag according to claim 2 wherein said polyolefin film is a polyethylene film.

Claim 5

The shipping bag according to claim 1, wherein said first and second inner panels are comprised of a nonwoven fluid permeable sheet of polypropylene filaments characterized by the ability to wick liquids through the sheet without absorbing any fluid.

Claim 6

The shipping bag according to claim 1 wherein said absorbent pads are comprised of a plurality of layers of absorbent material.

Claim 7

The shipping bag according to claim 5 wherein said absorbent pads are comprised of a layer of paper wadding and a layer of defiberized wood pulp.

Claim 8

The shipping bag according to claim 1 wherein said absorbent pad is impregnated with a bacteriastatic agent.

Claim 9

The shipping bag according to claim 1 wherein said bacteriastatic agent comprises chlorine bleach.

Claim 10

A shipping bag for containers of potentially biohazardous liquids characterized by the ability to absorb such liquid upon rupture of the containers and to protect persons handling the bag from contact with such liquid, said bag comprising: (a) first and second outer panels formed of liquid impervious polyethylene film connected along opposed side edges and one end to define an open top liquid impervious body portion; (b) liquid absorbing means confined within said body portion and comprising a pair of absorbent pads arranged adjacent each of said first and second outer panels, each pad being comprised of a layer of paper wadding and a layer of defiberized wood pulp; (c) first and second inner panels formed of liquid permeable hydrophobic sheet material made of nonwoven polypropylene filaments, wherein said inner panels are confined within said body portion and disposed parallel to said first and second outer panels and respectively connected therewith along said opposed side edges and opposite ends to define an open inner space in communication with said open top and separating said liquid absorbing means from said inner space, and wherein the nonwoven material is characterized by the ability to wick liquids therethrough without absorbing any fluid; and (d) closure means at said open top to sealingly close said inner space and retain any liquids within said body portion to protect persons handling the shipping bag from contact with potentially biohazardous liquid.

Claim 11

A shipping bag for containers of potentially biohazardous liquids characterized by the ability to absorb such liquid upon rupture of the containers and to protect persons handling the bag from contact with such liquid, said bag comprising: (a) first and second outer panels formed of liquid impervious polyethylene film connected along opposed side edges and one end to define an open top liquid impervious body portion; (b) liquid absorbing means confined within said body portion and comprising a pair of absorbent pads arranged adjacent each of said first and second outer panels, each pad being comprised of a layer of paper wadding and a layer of defiberized wood pulp; (c) first and second inner panels formed of liquid permeable hydrophobic sheet material made of nonwoven polypropylene filaments, wherein said inner panels are confined within said body portion and disposed parallel to said first and second outer panels and respectively connected therewith along said opposed side edges and opposite ends to define an open inner space in communication with said open top and separating said liquid absorbing means from said inner space, and wherein the nonwoven material is characterized by the ability to wick liquids therethrough without absorbing any fluid; and (d) closure means at said open top to sealingly close said inner space and retain any liquids within said body portion to protect persons handling the shipping bag from contact with potentially biohazardous liquid.

Claim 12

The shipping bag according to claim 9 wherein said panels are connected together by heat sealing.

Claim 13

The shipping bag according to claim 9 wherein said absorbent pad is impregnated with a bacteriastatic agent.
