Abstract
An electronic price label (EPL) which uses a two-part overlay arrangement to avoid stacking of permanent adhesive overlays. The EPL includes a housing having a front surface containing an aperture exposing the electronic display. A first record member is substantially permanently attached to the front surface of the electronic display. The first record member contains information that is substantially permanent, and includes legends for the electronic display. A second record member is removably attached to the first record member. The second record member contains product information that is likely to change.
Claims23
An electronic price label (EPL) comprising:
- an electronic display for displaying price information;
- a housing having a front surface containing an aperture exposing the electronic display;
- a first record member substantially permanently attached to the front surface of the electronic display using a first attachment device for displaying first information;
- and
- a second record member which is removably attached to the first record member using a second attachment device different than the first attachment device for displaying second information simultaneously with but different than the first information;
- wherein the second record member leaves at least a portion of the first information of the first record member exposed when the second record member is attached to the first record member.
An overlay system for an electronic price label (EPL) comprising:
- a first record member substantially permanently attached to a front surface of the electronic display using a first attachment device for displaying first information;
- and
- a second record member which removably attaches to the first record member using a second attachment device different than the first attachment device for displaying second information simultaneously with but different than the first information;
- wherein the second record member leaves at least a portion of the first information of the first record member exposed when the second record member is attached to the first record member.
A method of changing information displayed by an electronic price label (EPL) comprising the steps of:
- attaching a substantially permanent first overlay on a front surface of the EPL using a first attachment device, wherein the first overlay contains substantially permanent information;
- attaching a removable second overlay containing product information to the first overlay using a second attachment device different than the first attachment device, including the substep of leaving at least a portion of the first information of the first record member exposed so that the second information is displayed simultaneously with the first information;
- removing the second overlay from the first overlay when the information on the second overlay becomes incorrect;
- and
- attaching a removable third overlay to the first overlay in place of the second overlay using a second attachment device similar to the second attachment device, including the substep of leaving at least a portion of the first information of the first record member exposed so that the third information is displayed simultaneously with the first information, wherein the third overlay contains correct information.
