Abstract

A tamper evident bag has front and rear panels connected together along opposite first and second side edge margins and a bottom edge margins that define a bag interior and a first bag opening therebetween. The front and rear panels each have a tear line with a first end and a second end, the first and second ends being located at the first side edge margin. The first and second ends of each tear line being spaced part. The tear lines extend over the front and rear panels but remain spaced from the second side edge margin. Each tear line defines a respective tear out section on the front and rear panels. The tear out sections are joined along the first side edge margin and are configured to be removed to create a second bag opening.

First claim

What is claimed is:

1. A tamper evident bag comprising:
a front panel and a rear panel having front and rear surfaces and top, bottom, and opposite first and second side edge margins, the front and rear panels being connected together along the first and second side edge margins and the bottom edge margin to define a bag interior between the front surface of the rear panel and the back surface of the front panel, the front surface of the rear panel and the top edge margin of the front panel defining a first bag opening therebetween sized and shaped for inserting one or more items into the bag interior;
a closure panel configured to close the first bag opening, the closure panel mounted on the rear panel, closure panel including a flap portion and a handle mount portion; and
a handle connected to the bag, the handle and first bag opening both disposed adjacent to the top edge margins of the front and rear panels, the handle including a first handle member joined to the rear panel and a second handle member joined to the handle mount portion of the closure panel;
the front and rear panels each having a tear line with a first end and a second end, the first and second ends being located at the first side edge margin, the first and second ends being spaced from the top and bottom edge margins and from each other, each tear line extending over the front and rear panels defining a respective tear out section therein, the tear lines being everywhere spaced from the second side edge margin, the tear out sections being joined along the first side edge margin and configured to be removed to create a second bag opening in the front and rear panels.

2. The tamper evident bag of claim 1 wherein the bag has a height and a midpoint along the height of the bag is located on the tear out sections.

3. The tamper evident bag of claim 1 wherein the tear lines on the front and rear panels are aligned with each other.

4. The tamper evident bag of claim 1 wherein the tear lines are formed of perforations.

5. The tamper evident bag of claim 1 further comprising an adhesive member on the front panel positioned to adhere the closure panel to the front panel so as to close the first bag opening.

6. The tamper evident bag of claim 1 wherein the closure panel is joined to a front surface of the rear panel between the top edge margin of the rear panel and the top edge margin of the front panel.

7. The tamper evident bag of claim 1 further including at least one vent hole.

8. The tamper evident bag of claim 1 wherein the tear lines have a first segment extending from the first side edge margin toward the second side edge margin, a second segment positioned between the first segment and the bottom edge margin and extending from the first side edge margin toward the second side edge margin, and a third segment interconnecting the first and second segments.

9. The tamper evident bag of claim 1 further comprising a bottom panel connecting the bottom edge margin of the front panel to the bottom edge margin of the rear panel, and configured to define a surface on which an item in the bag may rest when the bag is carried by the handle.

10. The tamper evident bag of claim 1 wherein at least one of the tear out sections includes a finger section defined at least in part by a finger tear line, the finger section sized and shaped to be engaged by a finger to facilitate removal of the tear out sections.

11. The tamper evident bag of claim 10 wherein said at least one tear out section has a height, the finger section having a height that is less than the height of the tear out section, and wherein the finger section is configured to be separated from the tear out section along at least a portion of the finger tear line when the finger section is engaged by the finger to create a finger opening sized and shaped to receive the finger.

12. A tamper evident bag comprising:
a front panel and a rear panel having front and rear surfaces and top, bottom, and opposite first and second side edge margins, the front and rear panels being connected together along the first and second side edge margins and the bottom margins to define a bag interior between the front surface of the rear panel and the back surface of the front panel, the top edge margin of the front panel extending across the front surface of the rear panel at a location spaced from the top edge margin of the rear panel toward the bottom edge margin of the rear panel, the front surface of the rear panel and the top edge margin of the front panel define a first bag opening therebetween; and
a closure panel having top and bottom edge margins, the closure panel being secured to the rear panel and configured to close the first bag opening, the closure panel including a flap portion and a handle mount portion;
a first handle member joined to the rear; and
a second handle member joined to the handle mount portion of the closure panel,
wherein the front and rear panels further include tear out sections positioned along the first side edge margin and spaced from the top and bottom edge margins and second side edge margins of the front and rear panels, the tear out sections extending toward the second side edge margin along the front and rear panels, the tear out sections being configured to be removed to create a second bag opening.

13. The tamper evident bag of claim 12 wherein the top edge margins of the closure panel and the rear panel are co-extensive.

14. The tamper evident bag of claim 12 wherein the tear out sections are defined by perforations in the front and rear panels.

15. The tamper evident bag of claim 12 wherein at least one of the tear out sections includes a finger section defined at least in part by a finger tear line, the finger section sized and shaped to be engaged by a finger to facilitate removal of the tear out sections.
