Description

TECHNICAL FIELD

The presently disclosed subject matter relates generally to secure containers and more particularly to a tamper-evident bag seal and tamper-evident bags and methods.

BACKGROUND

Disposable containers for packaging, distributing, displaying or otherwise housing consumer items, such as food containers, are becoming increasingly important. For example, bags, such as paper bags, are used for distributing and/or carrying food items, such as take out or to-go food containers. Sometimes it is desirable that an item or items, such as food containers, be placed in, for example, a bag for ease of transport.

Unfortunately, it is a frequent occurrence that the containers may be tampered with by persons who wish to access the item or items in the containers. In taking steps to avoid this invasion of the container, many approaches in the nature of security and/or safety have been utilized. However, some of these security attempts have been easily circumvented and others have been very expensive.

One of the desirable features of security packaging is the characteristic that any tampering with the package produces a “tamper-evident” condition. With a “tamper-evident” condition, a consumer can visually detect that the container has been tampered. Unfortunately, many security attempts have been unsuccessful in that it is not fully evident that the security of the container has been breached. Consequently, new approaches are needed for incorporating tamper-evident features into containers.

DETAILED DESCRIPTION

The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying Drawings, in which some, but not all embodiments of the presently disclosed subject matter are shown. Like numbers refer to like elements throughout. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the presently disclosed subject matter set forth herein will come to mind to one skilled in the art to which the presently disclosed subject matter pertains having the benefit of the teachings presented in the foregoing descriptions and the associated Drawings. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.

In some embodiments, the presently disclosed subject matter provides a tamper-evident bag seal and/or tamper-evident bags and methods.

In some embodiments, the presently disclosed tamper-evident bag seal is provided as an addon device to an existing bag. Once installed on the bag, the presently disclosed tamper-evident bag seal provides a tamper evident sign or indicator that shows that the bag has been opened and potentially that the contents of the bag have been tampered with. The tamper-evident bag seal may be, for example, a paper or paperboard panel (or any other suitable material) that folds over the handles of an existing bag and is secured to the sides of the bag. The tamper-evident bag seal may be provided in different sizes (e.g., small, medium and large) that correlate to different size bags and/or bag handle sizes. The tamper-evident bag seal may be used with bags having several different handle configurations, such as, but not limited to, plastic, plastic rope, plastic ribbon, injection molded plastic, paper, and rope handles.

The presently disclosed tamper-evident bag seal may include, for example, a fold-over panel or card that has double sided tape on each side of the fold-over card. Further, the fold of the fold-over card may be perforated to provide a tear line. The fold-over card may also include an opening for fitting over the handles of the bag. After the contents are placed into the bag, the fold-over card that fits the bag (e.g., small, medium and large) fits over the handles, the adhesive liner may then be removed from each side of the card, and then the sides of fold-over card may be folded over and secured to the sides of the bag. Accordingly, the tamper-evident bag seal is used to seal the bag until the handles are pulled in opposite directions tearing the card at the perforation and allowing access to the contents.

In some embodiments, the presently disclosed subject matter provides tamper-evident bags and methods. In some embodiments, the presently disclosed tamper-evident bags can be a food carry out/to-go bag, carry bag, hand bag, shopping bag, or gift bag formed, for example, of paper, plastic, and/or cardboard.

In one embodiment of the presently disclosed tamper-evident bags, the tamper-evident bag includes a sealable flap for securing the bag in the closed state. Further, the tamper-evident bag includes a perforated fold, seam, or line along the sealable flap that is the mechanism for opening the bag. Namely, to open the sealed flap and thereby open the bag, a user must tear across the perforated fold, seam, or line. The compromised perforated fold, seam, or line provides easy visual evidence that the bag has been opened or tampered with. Accordingly, in this embodiment, the perforated fold, seam, or line is the tamper-evident feature of the tamper-evident bag.

In another embodiment of the presently disclosed tamper-evident bags, the tamper-evident bag includes a sealable flap for securing the bag in the closed state. Further, the tamper-evident bag includes a tear-away strip along the sealable flap that is the mechanism for opening the bag. Namely, to open the sealed flap and thereby open the bag, a user must tear away the tear-away strip. The compromised tear-away strip provides easy visual evidence that the bag has been opened or tampered with.

Accordingly, in this embodiment, the tear-away strip is the tamper-evident feature of the tamper-evident bag.

Referring now to FIG. 1 is a perspective view of an example of the presently disclosed tamper-evident bag seal 100 that is partially installed on a bag 150.
