Abstract

A tamper evident bag includes a top panel and a bottom panel connected together to define a bag interior between the top and bottom panels. The top panel defines a receiving opening sized and shaped for inserting one or more items into the bag interior. The top and bottom 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 apart. The tear lines extend over the top and bottom panels and define respective tear out sections of the top and bottom panels. The tear out sections are joined along the first side edge margin and are configured to be removed to create an exit opening.

First claim

What is claimed is:

1. A tamper evident bag comprising:
a top panel and a bottom panel having top and bottom surfaces and front, rear, and opposite first and second side edge margins, the top and bottom panels being connected together along the front, rear and first and second side edge margins to define a bag interior between the top surface of the bottom panel and the bottom surface of the top panel, the top panel defining a receiving opening sized and shaped for inserting one or more items into the bag interior; and
a handle connected to the top panel;
the top and bottom 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 of the tear line being spaced from the front and rear edge margins and from each other, each tear line extending over the top and bottom panels defining a respective tear out section therein, the tear out sections being joined along the first side edge margins and configured to be removed to create an exit opening in the top and bottom panels;
wherein the tear lines are everywhere spaced from the front, rear and second side edge margins.

2. The tamper evident bag of claim 1 wherein the bag has a width extending between the front and rear edge margins and a midpoint along the width of the bag, the midpoint being located on the tear out sections.

3. The tamper evident bag of claim 1 wherein the tear lines on the top and bottom 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 wherein the top and bottom panels are connected together along the first side edge margin with a first gusset and second side edge margin with a second gusset.

6. The tamper evident bag of claim 1 wherein the top and bottom panels each further include a second tear line with a first end and a second end, the first end of the second tear line being located at the first side edge margin and the second end of the second tear line being located at the second side edge margin, each second tear line being adjacent to and generally parallel with the front edge margin, the second tear lines extending over the top and bottom panels defining a respective second tear out section therein, the second tear out sections being joined along the front edge margin and configured to be removed to create a front margin exit opening between the top and bottom panels.

7. The tamper evident bag of claim 6 wherein the top and bottom panels each further include a third tear line with a first end and a second end, the first end of the third tear line being located at the first side edge margin and the second end of the third tear line being located at the second side edge margin, each third tear line being adjacent to and generally parallel with the rear edge margin, the third tear lines extending over the top and bottom panels defining a respective third tear out section therein, the third tear out sections being joined along the rear edge margin and configured to be removed to create a rear margin exit opening between the top and bottom panels.

8. The tamper evident bag of claim 1 wherein the handle is configured to close the receiving opening.

9. The tamper evident bag of claim 8 wherein the top panel comprises a first top panel member and a second top panel member, the first top panel member having front, rear, and opposite first and second side edge margins, the second top panel member having front, rear, and opposite first and second side edge margins, each of the front, rear, and first side edge margins of the first top panel member being connected to at least a portion of the front, rear, and first side edge margins of the bottom panel, respectively, and each of the front, rear, and second side edge margins of the second top panel member being connected to at least a portion of the front, rear, and second side edge margins of the bottom panel, respectively.

10. The tamper evident bag of claim 9 wherein the receiving opening is defined between the second side edge margin of the first top panel member and the first side edge margin of the second top panel member.

11. The tamper evident bag of claim 10 wherein the handle comprises a first handle panel connected to the first top panel member and a second handle panel connected to the second top panel member.

12. The tamper evident bag of claim 11 wherein the first handle panel is connected to the second side edge margin of the first top panel member and the second handle panel is connected to the first side edge margin of the second top panel member.

13. The tamper evident bag of claim 11 further comprising an adhesive member on the second handle panel positioned to adhere to the first handle panel so as to close the receiving opening.

14. The tamper evident bag of claim 13 wherein the first handle panel defines a first aperture and the second handle panel defines a second aperture, the first and second apertures being configured to receive a hand of a user so the user can grasp the bag.

15. The tamper evident bag of claim 11 further including at least one section extending from the first handle panel around the bag to the second handle panel that does not cross any line of weakness formed into the bag whereby a weight carried by the bag can be supported from the first and second handle panels without passing through any line of weakness.

16. A tamper evident bag comprising:
a top panel and a bottom panel having top and bottom surfaces and front, rear, and opposite first and second side edge margins, the top and bottom panels being connected together along the front, rear and first and second side edge margins to define a bag interior between the top surface of the bottom panel and the bottom surface of the top panel, the top panel defining a receiving opening sized and shaped for inserting one or more items into the bag interior, the top and bottom panels having a bag width extending between the front and rear edge margins; and
a handle connected to the top panel;
the top and bottom panels each having a tear line with a first end and a second end, the first end being located at the first side edge margin and the second end being located at the second side edge margin, each tear line being adjacent to and generally parallel with the front edge margin, the tear lines extending over the top and bottom panels defining a respective tear out section therein, each tear out section extending from the tear line to the front edge margin of the respective top and bottom panels, each tear out section having a tear out section width extending between the tear line and the front edge margin, the tear out section width being greater than zero and equal to or less than a quarter of the bag width, the tear out sections being joined along the front edge margins of the top and bottom panels, the tear out sections being configured to be removed from the top and bottom panels to create a front margin exit opening between the top and bottom panels, the tear out sections removing the connected front edge margins of the top and bottom panels from the top and bottom panels when the tear out sections are removed from the top and bottom panels to create the front margin exit opening.

17. The tamper evident bag of claim 16 wherein the top and bottom panels each further include a second tear line with a first end and a second end, the first end of the second tear line being located at the first side edge margin and the second end of the second tear line being located
