Abstract

A container opening device, container lid, or can top with a decorated feature, or in the case of an opening device, a symbolically shaped pull tab for attachment to a container to perform the dual functions of opening the container and decorating the container for equity, identification or promotional purposes. The pull tab may open the container by acting as a lever which presses against a tear strip in the container top defined by a tear line to separate the tear strip from the container top and open the container. The pull tab may perform a decorative and promotional function by having a decoration or a symbolic shape that is to be recognized as a picture, trademark, icon, character, or other symbolic item or logo. The decoration can be made by applying color, printing, embossing, laser removal of a coating and labels to the pull tab, lid or container. The pull tab or decoration can take the shape and design of corporate logos, trademarks, icons, etc. In an alternative embodiment, the pull tab may have a weakened portion so that a piece of the pull tab may be removable from the container as a token or memento.

Claims

1. A container opening device comprising:

a pull tab exhibiting a substantially planar member having an attachment point for attachment to a container with a closed grab portion oriented to one side of said attachment point and a nose portion oriented on an opposite side of said attachment point;

said pull tab actuatable to open the container;

an epoxy coating layer disposed on said pull tab; and

a laser etched image defined on said pull tab;

wherein said image is created by a localized laser removal of said coating layer to expose an uncoated surface of the pull tab.

2. A container opening device according to claim 1, wherein said pull tab is made of a composite material.

3. A container opening device according to claim 1, wherein said pull tab is made of a natural material.

4. A container opening device according to claim 1, wherein said pull tab is made of a synthetic material.

5. A container opening device comprising:

a pull tab-exhibiting a substantially planar member having an attachment point for attachment to a container with a closed portion oriented to one side of said attachment point and a nose portion oriented on an opposite side of said attachment point,

said pull tab actuable to open the container;

an epoxy coating layer disposed on said pull tab;

a laser etched image defined on said pull tab;

wherein said image is created by a localized laser removal of said coating layer to expose an uncoated surface of the pull tap, and

wherein said pull tab is made of metal.

6. A container opening device according to claim 5, wherein said metal is aluminum.

7. A container opening device according to claim 6, wherein said aluminum is an alloy.
