Plastic bag with imperforated tear area
A plastic specimen bag ( 10 ) includes a front wall ( 20 ) and a rear wall ( 22 ) that are joined together to define a containment portion ( 32 ) having a bottom ( 24 ), side edges ( 26, 28 ), and a top opening ( 30 ). The plastic specimen bag ( 10 ) further includes a first closure (C 1 ) located between the bottom ( 24 ) and the top opening ( 30 ) for selectively closing the containment portion ( 32 ). To facilitate opening the specimen bag ( 10 ), the specimen bag ( 10 ) includes a first grip enhancing profile ( 50 ) and a second grip enhancing profile ( 52 ) that are formed in the front wall ( 20 ) and spaced apart from one another to define a tear area ( 54 ) therebetween. The tear area ( 54 ) is located between the closure (C 1 ) and the bottom ( 24 ).
1. A plastic specimen bag, comprising:

a first grip enhancing profile and a second grip enhancing profile formed in said front wall and spaced apart from one another to define therebetween a tear area for opening said containment portion, said tear area being located between said closure and said bottom;
wherein each of said first grip enhancing profile and said second grip enhancing profile comprises a series of raised ribs;
wherein the raised ribs in each said series of raised ribs are increasingly spaced apart as each said series approaches said tear area.
2. The specimen bag of claim 1 , said tear area not having a thickness that is substantially less than the thickness of the remainder of said front wall.
3. The specimen bag of claim 1 , wherein said first grip enhancing profile and said second grip enhancing profile define a front wall tear area; and
wherein said specimen bag further comprises a third grip enhancing profile and a fourth grip enhancing profile formed in said rear wall and spaced apart from one another to define therebetween a rear wall tear area, said rear wall tear area being located between said closure and said bottom; and
wherein said front wall tear area is substantially aligned with said rear wall tear area.
4. The specimen bag of claim 3 , wherein said third grip enhancing profile is substantially aligned with said first grip enhancing profile and said fourth grip enhancing profile is substantially aligned with said second grip enhancing profile.
5. The specimen bag of claim 1 , further comprising a flap joined to said rear wall to form a pouch, wherein said flap includes a severance line aligned with said tear area.
6. The specimen bag of claim 1 , wherein said first closure comprises a male profile on one of said front wall and sear rear wall and a female profile on the other of said front wall and said rear wall, wherein said male profile and said female profile are capable of engaging one another to form a seal.
7. The specimen bag of claim 1 , further comprising a second closure located between said first closure and said top opening.
8. The specimen bag of claim 7 , wherein each of said first and second closures comprises a male profile on one of said front wall and said rear wall and a female profile on the other of said front wall and said rear wall, wherein said male profile and said female profile are capable of engaging one another to form a seal.
9. The specimen bag of claim 7 , wherein at least one of said first closure and said second closure is a non-releasable closure.
10. The specimen bag of claim 1 , further comprising means for initiating a tear in said tear zone.
11. The specimen bag of claim 10 , wherein said tear initiation means comprises a notch in at least one of said side edges in said tear area.
12. The specimen bag of claim 1 , wherein said first grip enhancing profile and said second grip enhancing profile extend substantially perpendicular to said side edges.
13. The specimen bag of claim 1 , wherein said first grip enhancing profile and said second grip enhancing profile extend at an angle with respect to said side edges.
14. The specimen bag of claim 1 , wherein said first grip enhancing profile and said second grip enhancing profile extend between said side edges.
15. A plastic specimen bag, comprising:
a front wall and a rear wall joined together to define a containment portion having a bottom, side edges, and a top opening; and
a first closure located between said bottom and said top opening for selectively closing said containment portion; and
a first grip enhancing profile and a second grip enhancing profile formed in said front wall and spaced apart from one another to define therebetween a tear area for opening said containment portion, said tear area being located between said closure and said bottom;
wherein each of said first grip enhancing profile and said second grip enhancing profile comprises a series of raised ribs;
wherein the raised ribs in each said series of raised ribs are decreasingly raised as each said series approaches said tear area.
16. A plastic specimen bag, comprising:
a front wall and a rear wall joined together to define a containment portion having a bottom, side edges, and a top opening; and
a first closure located between said bottom and said top opening for selectively closing said containment portion; and
a first grip enhancing profile and a second grip enhancing profile formed in said front wall and spaced apart from one another to define therebetween a tear area for opening said containment portion, said tear area being located between said closure and said bottom;
wherein each of said first grip enhancing profile and said second grip enhancing profile comprises a series of raised ribs;
wherein the raised ribs in each said series of raised ribs decrease in width as each said series approaches said tear area.
17. A plastic specimen bag, comprising:
a front wall and a rear wall joined together to define a containment portion having a bottom, side edges, and a top opening; and
a first closure located between said bottom and said top opening for selectively closing said containment portion; and
a first grip enhancing profile and a second grip enhancing profile formed in said front wall and spaced apart from one another to define therebetween a tear area for opening said containment portion, said tear area being located between said closure and said bottom;
further comprising a flap joined to said rear wall to form a pouch, wherein said flap includes a severance line aligned with said tear area;
wherein said first grip enhancing profile and said second grip enhancing profile define a front wall tear area; and
wherein said specimen bag further comprises a third grip enhancing profile and a fourth grip enhancing profile formed in said flap and spaced apart from one another to define therebetween a flap tear area, said flap tear area being substantially aligned with said front wall tear area.
