Description
BACKGROUND OF THE INVENTION

This invention relates generally to monitoring a shelf life of a product and, more particularly, to a container configured to monitor the remaining shelf life of a product stored within the container.

The food industry is a large and diverse industry that provides food products to consumers throughout the world. Food safety is an important issue to the food industry. The shelf life of food is a critical factor impacting food safety, consumer acceptability of food and the economics of the food industry. Accordingly, the ability to monitor the shelf life of a food product is critical to the food industry.

The shelf life of food is generally defined as the period of time a food vendor can properly store a food product before selling the food product to the public for consumption. Different types of food may have different shelf lifes. For example, fresh meat may have a shelf life of 30 days when properly stored within a refrigerated area, while fresh fish may have a shelf life of 10 days. In other words, the shelf life of food is a unit of measure that indicates the period of time that the vendor (i.e., a butcher/grocer) can properly store the product before selling it to the public. Because the shelf life of food directly impacts food safety and the economics of the food industry, it is important for a food vendor to be able to monitor the shelf life of food products such that the food products are timely sold. By monitoring the shelf life of its food products, a food vendor is better able to control food safety and reduce food waste.

The food industry, however, lacks a device for easily identifying whether a food product is being sold within its shelf life. For example, at least one known process currently employed in the meat industry for monitoring the age of food includes placing labels on the boxes used for shipping the meat to the vendor wherein the labels include an expiration date printed thereon. However, the labels currently used are not easy to read from a distance and do not show how many days are remaining on the shelf life of a product, but rather only show the date by which the product is to be sold. Accordingly, when using this type of labeling system, a user must be close enough to read the box label and must calculate the remaining life from the date printed on the case. The current labeling system results in loss of worker time and increased food waste.

There are at least some patents that describe processes and/or devices for tracking the age of food. For example, U.S. Pat.

DETAILED DESCRIPTION OF THE INVENTION

Exemplary embodiments of the methods and systems that facilitate monitoring a remaining shelf life of a product stored within a container are described below in detail. Specifically, the exemplary embodiments below describe a device sometimes referred to as the “Electronic Date Coder.” The methods and systems include providing a container having a bottom and at least one side extending from the bottom, providing a timer device that includes an integrated circuit programmed as a timer and an output device electrically coupled to the integrated circuit, attaching the timer device to the container, and coupling a display to the timer device in communication with the output device for displaying the remaining shelf life of the product stored within the container. Typically, the Electronic Date Coder device may be used for monitoring the shelf life of food products, but it can also be used for any product that may have a shelf life or any other critical period of time associated therewith that may require monitoring.

More specifically, in the example embodiment, the Electronic Date Coder device will automatically determine the remaining shelf life of a product stored within a container, and will visually signal vendors within a distribution chain of the remaining shelf life of the products stored within the container. Vendors may include any person or party involved in the production, packaging, distribution, or sale of a product. In the example embodiment, the Electronic Date Coder device can signal vendors at distances of up to fifty feet. The Electronic Date Coder device therefore enables users to more efficiently handle products in a distribution chain, for example food products, while also reducing labor costs. Furthermore, the present invention may also reduce product spoilage through more accurate and timely distribution of perishable products.

In the example embodiment, the Electronic Date Coder monitors the remaining shelf life of a product stored within a container. The Electronic Date Coder includes a display substrate which can be adhered to the side of a paperboard, corrugated paper, or plastic container in which a product that is being monitored is stored. The Electronic Date Coder further includes a timer device having an integrated circuit programmed as a timer and an output device coupled to the circuit. The output device may include a plurality of light emitting diodes. In one embodiment, the timer device is positioned within a depressed section of the display substrate. In another embodiment, the display substrate does not include a depressed section but rather is flexible such that the display substrate encases the timer device when the display substrate is adhered to the container.

The timer device is programmed with the shelf life of the product stored within the container, and is programmed with predetermined time intervals that comprise the product's shelf life. Each time interval is associated with one of the light emitting diodes of the output device. A display unit on the front side of the display substrate is divided into sections, each having indicia to indicate the time intervals. Each section further includes an aperture through which one of the light emitting diodes of the output device are received.

In operation, the timer is configured to be activated such that the timer records a start time of when a product is stored within a container. The timer is further programmed to record the time the product is stored within the container from the start time through the shelf life of the product. In other words, the timer device is programmed as a countdown timer, counting down from the time of activation through the shelf life of the associated product. The time the product is stored within the container is divided into time intervals. Each time interval is indicated on the display unit and is associated with one of the light emitting diodes such that during the first time interval (e.g. 30-23 days remaining), the corresponding light emitting diode is illuminated by the timer device. When each subsequent time interval is reached by the timer device, the previously activated light emitting diode is no longer illuminated and the next corresponding light emitting diode is activated to indicate the next time interval on the display unit. This process is repeated until the shelf life expires.

For example, a product may have a shelf life of 30 days. Accordingly, the Electronic Date Coder would be programmed for a shelf life of 30 days, and may have five time intervals that total the 30 day shelf life of the product. Likewise, the display unit would have indicia indicating the five time intervals. Each indicia on the display unit is further associated with a light emitting diode that is positioned within an aperture. The light emitting diodes may be covered by colored lamps to further signal the different time intervals of the product shelf life. The colored lamps may include blue, green, orange, yellow, and red. The five time intervals are each associated with a different color. For example, 30 to 23 days remaining in the shelf life may be associated with blue, 22 to 15 days remaining may be associated with green, 14 to 6 days remaining may be associated with orange, 5 to 1 days remaining may be associated with yellow, and 0 days remaining may be associated with red.

When the product is first stored in a container the timer is started and the first diode indicating 30 to 23 days, having a blue lamp, is activated. When the next time interval is recorded by the timer, the diode having a blue lamp is deactivated and the next diode indicating 22 to 15 days, having a green lamp, subsequently becomes activated. As such, when each following time interval is reached, the currently activated diode is no longer illuminated and the next subsequent diode becomes activated until the shelf life expires and the diode indicating 0 days, having a red lamp, is activated. The light emitting diodes are visible for up to fifty feet and allow an operator within a distribution chain to quickly determine the remaining shelf life of a product without having to be close enough to read a box label. In one embodiment, the timer switch can be reset and the timer reused to indicate the shelf life of another product. In an alternative embodiment, the switch cannot be reset because it is tamper proof. In this particular embodiment, the tamper proof switch prevents the timer from being reset so as to prevent the sale a product after its expiration date.

As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural said elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present invention are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

The methods and systems are not limited to the specific embodiments described herein. In addition, the components of each apparatus and each method can be practiced independent and separate from the other components and methods described herein.

Integrated circuit 16 is further programmed with a shelf life of a product, and with predetermined time intervals that total the overall shelf life. Integrated circuit 16 communicates a signal indicative of a particular time interval to the output circuitry 18. The signal received from integrated circuit 16 illuminates one of the light emitting diodes 12. By observing the light emitting diodes 12 on the front of display substrate 11, an operator can determine the remaining shelf life of a product.

FIG. 2 is a top view of an alternative embodiment of an Electronic Date Coder 100. Components in Electronic Date Coder 100, identical to components of Electronic Date Coder 10 (shown in FIG. 1), are identified in FIG. 2 using the same reference numerals as used in FIG. 1. Electronic Date Coder 100 of FIG. 2 further includes a display substrate 110 having a depressed section 120 and attachment surfaces 122. Specifically, display substrate 110 includes depressed section 120 and attachment surfaces 122 located on a rear side of display substrate 110. Depressed section 120 has a width that is less than a width of the display substrate 11, but of sufficient width such that battery 14, integrated circuit 16, and output circuitry 18 can be retained therein. Depressed section 120 further includes a depth such that battery 14, integrated circuit 16, and output circuitry 18 can be positioned at least partially within depressed section 120.

Attachment surfaces 122 of the display substrate 110 are located on the rear side of display substrate 110. Attachment surfaces 122 are configured to receive glue, adhesive or other means of attachment for adhering to a container (not shown). The configuration of display substrate 110 enables Electronic Date Coder 100 to be attached substantially flush to a container (not shown) such that the electronic components are housed within depressed section 120 and between the container and display substrate 110. Battery 14, integrated circuit 16, output circuitry 18, and light emitting diodes 12 operate in the same fashion as described in FIG. 1.

FIG. 3 is a rear view of Electronic Date Coder device 10 (shown in FIG. 1). Electronic Date Coder 10 includes display substrate 11, battery 14, integrated circuit 16, and output circuitry 18. Display substrate 11 includes a rear side 150. Battery 14, integrated circuit 16, and output circuitry 18 are all coupled to rear side 150 of display substrate 11.

In the example embodiment, rear side 150 also includes an attachment surface 152. Attachment surface 152 is configured to receive glue, adhesive or other means of attachment for adhering display substrate 11 to a container (not shown). In addition, display substrate 11 is flexible such that display substrate 11 encases battery 14, integrated circuit 16, and output circuitry 18 when display substrate 11 is adhered to the container.

FIG. 4 is a front view of Electronic Date Coder 10 attached to a corrugated container 300. Electronic Date Coder device 10 includes display substrate 11. Display substrate 11 includes a front side 302. In the example embodiment, front side 302 includes indicia 304, a shelf life indicator 306, and light emitting diodes 308. Indicia 304 further includes time intervals 310, and a plurality of multi-color sections 312. Display substrate 11 also includes a plurality of apertures 314, wherein each aperture 314 is configured to receive one of the light emitting diodes 308.

In the example embodiment, time intervals 310 include five time intervals each having a separate color associated therewith. Each time interval 310 includes indicia 304 indicating the number of days remaining in the shelf life programmed for the specific Electronic Date Coder 10.

For example, Electronic Date Coder 10 is programmed for a 30 day shelf life. The first time interval 310 includes indicia 304 showing 30 to 23 days remaining in the shelf life and is associated with the color blue. The next time interval 310 includes indicia 304 showing 22 to 15 days remaining and is associated with the color green. The next time interval 310 includes indicia 304 showing 14 to 6 days remaining and is associated with the color orange. The next time interval 310 includes indicia 304 showing 5 to 1 days remaining and is associated with the color yellow. The final time interval 310 includes indicia 304 showing 0 days remaining and is associated with the color red.

In operation, a product having a shelf life of 30 days is stored in container 300. Electronic Date Coder 10 is then started and the first diode indicating 30 to 23 days, having a blue lamp, is activated. When the next time interval is recorded by Electronic Date Coder 10, the diode having a blue lamp is deactivated and the next diode indicating 22 to 15 days, having a green lamp, subsequently becomes activated. As such, when each of the following time intervals is reached, the currently activated diode is no longer illuminated and the next subsequent diode becomes activated until the shelf life expires and the diode indicating 0 days, having a red lamp, is activated. The light emitting diodes are visible for up to fifty feet and allow an operator within a distribution chain to quickly determine the remaining shelf life of a product without having to be close enough to read a box label. After use, the Electronic Date Coder can be reset and used to indicate the shelf life of another product.

Integrated circuit 408 includes eight inputs 416 and eight outputs 418. When in operation, battery 402 provides power to integrated circuit 408. Integrated circuit 408 is programmed as a timer. Integrated circuit 408 is further programmed with a shelf life of a product, and with predetermined time intervals that total the overall shelf life. Integrated circuit 408 communicates a signal indicative of a particular time interval to the output circuitry 410. The signal received from integrated circuit 408 illuminates one of the light emitting diodes 412. By observing the light emitting diodes 412 on the front of the display substrate, an operator can easily see the remaining shelf life of a product.
