Abstract

A reclosable plastic bag includes two panels sealed to form a container having a bottom and an openable top. The plastic bag further includes lips that are adjacent to the openable top and which are initially joined to one another by a removable element. The removable element when attached indicates that the bag has not yet been used. When the removable element is no longer attached this indicates that the bag may have been used (contaminated). The reclosable plastic bag also includes a closure element for sealing and unsealing the openable top of the bag.

Claims (18)

1. A reclosable plastic bag, comprising:

A. a first panel attached to a second panel to form a container having a bottom and a sealed top edge;

B. a primary closure located between the bottom and the sealed top edge, comprising:

i. a primary female profile on the first panel of the container,

ii. a primary male profile on the second panel of the container that is configured to engage selectively with the primary female profile;

C. a removable element of the container extending from the sealed top edge to a separation line located between the sealed top edge and the primary closure and that when still attached to the container indicates that the container has not yet been opened;

D. a first lip portion of the first panel extending from the primary closure to the separation line and including a first right edge and a first left edge; and

E. a second lip portion of the second panel extending from the primary closure to the separation line and including a second right edge and a second left edge; in which:

i. the first right edge is attached to the second right edge from the primary closure to a right cutout portion of the first and second lip portions in which the first right edge is not attached to the second right edge and

ii. the first left edge is attached to the second left edge from the primary closure to a left cutout portion of the first and second lip portions in which the first left edge is not attached to the second left edge.

2. The reclosable plastic bag of claim 1 further comprising a secondary closure located between the bottom and the primary closure, comprising:

A. a secondary female profile on the first panel of the container,

B. a secondary male profile on the second panel of the container that is configured to engage selectively with the secondary female profile.

3. The reclosable plastic bag of claim 1 in which the primary male profile further comprises an asymmetrical barb oriented in a direction to facilitate disengaging the primary male from the primary female profile by pulling the first lip portion away from the second lip portion.

4. The reclosable plastic bag of claim 3 further comprising a secondary closure located between the bottom and the primary closure, comprising:

A. a secondary female profile on the first panel of the container,

B. a secondary male profile on the second panel of the container that is configured to engage selectively with the secondary female profile.

5. The reclosable plastic bag of claim 1 in which the first lip portion and the second lip portion are scored, perforated, or otherwise pre-formed along the separation line to facilitate removing the removable element.
