Recyclable container closure having informational and/or anti-counterfeiting capabilities
View Patent ↗A “smart” closure system, apparatus, and method are described. The closure includes mechanical solution, used in conjunction with wireless technologies and/or web-based or remote authentication, verification, and serialization via a mobile computing device, to provide information about the closure and the contents concealed within that closure. Further, the construction of the closure allows for any and all non-recyclable components of the wireless technologies to be removed so as to enable the closure to be recycled and/or converted to post consumer resin.
1. A smart closure, rotatably attachable to a container, comprising:
a cap, the cap having a panel, a peripheral skirt extending axially away from a bottom facing of the panel and a sealing flange, plate engagement features, and a plurality of tag engagement posts all positioned on the bottom facing, said sealing flange being arranged coaxially within the skirt and said plate engagement features and plurality of tag engagement posts being arranged within an area defined by the sealing flange;
a sealing plate having at least one peripheral stopper to engage a corresponding stopper formed on a container, and cap engagement features provided on a top facing, said sealing plate being sized to be received within the skirt of the cap;
a wireless tag having at least one frangible appendage, said wireless tag being positioned between the cap and the plate so that the tag is carried on the engagement posts;
wherein the cap and sealing plate are coupled together via the cap and plate engagement features to form a closure with the wireless tag held between the cap and the sealing plate; and
wherein, after the closure has been tightened onto a container, the frangible appendage ruptures when the closure is thereafter loosened by rotation relative to the container.
2. The smart closure of claim 1 wherein the plate engagement features of the cap include one or more axially extending ribs or projections, said axially extending ribs or projections received within a corresponding arcuate gap or slot formed on the top facing of the sealing plate and wherein said corresponding arcuate gap or slot allows the sealing plate to rotate freely in comparison to the cap for a limited range of motion.
3. The smart closure of claim 1 wherein the plate engagement features include one or more beads, grooves, or snap fittings formed on a radial facing of the cap which are received in a cooperating formations, provided as cap engagement features, on a radial facing of the sealing plate.
4. The smart closure of claim 3 wherein at least two separate and axially spaced apart beads, grooves, or snap fittings are included as plate engagement features and at least two separate and axially spaced apart cooperating formations are included as cap engagement features so that a first set of plate and cap engagement features are coupled when the cap is initially attached to the plate and a second set of plate and cap engagement features are subsequently coupled after the closure is tightened onto a container.
5. The smart closure of claim 3 wherein the radial facing of the cap is positioned on the sealing flange.
6. The smart closure of claim 3 wherein the radial facing of the sealing plate is positioned on a peripheral groove on the top facing.
7. The smart closure of claim 3 wherein the cap includes a central engagement cylinder on the bottom facing, said central engagement cylinder cooperating with a corresponding engagement cylinder formed on the top facing of the sealing plate.
8. The smart closure of claim 3 wherein the cap includes at least one axial wall extending from the bottom facing to form a plug seal with a container neck edge.
9. The smart closure of claim 1 wherein the cap includes a central engagement cylinder on the bottom facing, said central engagement cylinder cooperating with a corresponding engagement cylinder formed on the top facing of the sealing plate.
10. The smart closure of claim 9 wherein the radial facing of the cap is positioned on the central engagement cylinder.
11. The smart closure of claim 9 wherein the radial facing of the sealing plate is positioned on the corresponding engagement cylinder.
12. The smart closure claim 1 wherein the cap includes at least one axial wall extending from the bottom facing to form a plug seal with a container neck edge.
13. The smart closure of claim 1 wherein the wireless tag includes apertures proximate to the frangible appendage.
14. The smart closure of claim 1 wherein the wireless tag includes peripheral apertures spaced apart and sized to receive the engagement posts of the cap.
