Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-24 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kreinbrink (US2021/0179323). 1. A polyester resin closure (Fig. 4) that mounts onto a finish of a container, the polyester resin closure comprising: an outer layer (in the below annotated Fig. 4) that comprises: an outer layer annular wall (in the below annotated Fig. 4); and an outer layer outer cylindrical wall (120) that extends downwardly from the outer layer annular wall, wherein the outer layer outer cylindrical wall comprises a plurality of knurls (121); an inner layer (220 and 210) that comprises: an inner layer annular wall (210); and an inner layer outer cylindrical wall (220) that extends downwardly from the inner layer annular wall, wherein an inner surface of the inner layer outer cylindrical wall comprises internal threads (221) configured to engage with the finish; a tamper evidence feature (230 and 232) that engages with a tamper evidence ledge (15) of the finish. 2. The polyester resin closure of claim 1, wherein the tamper evidence feature comprises an outer layer folded band disposed radially outward along a bottom circumference of the outer layer outer cylindrical wall (Figs. 1-8). 3. The polyester resin closure of claim 2, wherein the tamper evidence feature further comprises an inner layer folded band that is configured to form a groove in which the outer layer folded band confronts and locks within (Figs. 1-8). 4. The polyester resin closure of claim 1, wherein the polyester resin comprises polyethylene terephthalate, polyethylene furandicarboxylate, or a copolymer of polyethylene terephthalate and polyethylene furandicarboxylate (Figs. 1-8). 5. The polyester resin closure of claim 1, wherein the outer layer comprises a different polyester resin than the inner layer (paragraph 0033). 6. The polyester resin closure of claim 1, wherein the plurality of knurls is distributed circumferentially about an outer surface of the outer layer outer cylindrical wall (Figs. 1-8). 7. The polyester resin closure of claim 1, wherein the outer layer further comprises: (i) an outer layer inner depression wall that extends downwardly from the outer layer annular wall; and (ii) an outer layer lower wall that extends across a bottom of the outer layer inner depression wall (Figs. 1-8). 8. The polyester resin closure of claim 7, wherein the inner layer further comprises: an inner layer inner depression wall that extends downwardly from the inner layer annular wall; and an inner layer lower wall that extends across a bottom of the inner layer inner depression wall (Figs. 1-8). 9. The polyester resin closure of claim 8, wherein the outer layer lower wall includes a first shaped downward depression, and wherein the inner layer lower wall includes a second shaped downward depression (Figs. 1-8). 10. The polyester resin closure of claim 9, wherein the first shaped downward depression is configured to engage with and lock axially against the second shaped downward depression (Figs. 1-8). 11. The polyester resin closure of claim 7, wherein the inner layer inner depression wall is configured such that an outwardly facing surface of the inner layer inner depression wall has an interference fit with an outwardly facing surface of the finish for sealing against the outwardly facing surface of the finish (Figs. 1-8). 12. The polyester resin closure of claim 11, wherein the amount of interference in the interference fit is from 0.02 mm to 0.2 mm (Figs. 1-8). 13. The polyester resin closure of claim 11, wherein the amount of interference in the interference fit is about 0.05 mm (Figs. 1-8). 14. The polyester resin closure of claim 8, wherein the inner layer lower wall is configured to change shape in response to pressurized contents within the interior of the container (Figs. 1-8). 15. The polyester resin closure of claim 14, wherein the inner layer lower wall has a concave upward shape that becomes a concave downward shape when pressure is applied by pressurized contents within the interior of the container (Figs. 1-8). 16. The polyester resin closure of claim 14, wherein the lower wall is configured to increase pressure on a sealing interface between the inner layer inner cylindrical wall and the finish (Figs. 1-8). 17. The polyester resin closure of claim 1, wherein the tamper evidence feature comprises a pull tab that is configured such that the pull tab must be at least partially removed before the closure can be disengaged from the finish (Figs. 1-8). 18. The polyester resin closure of claim 1, wherein a plurality of internal knurls is disposed about the circumference of an inner surface of the tamper evidence feature (Figs. 1-8). 19. The polyester resin closure of claim 18, wherein the plurality of internal knurls is distributed evenly about the circumference of the inner surface of the tamper evidence feature (Figs. 1-8). 20. The polyester resin closure of claim 18, wherein the plurality of internal knurls is distributed unevenly about the circumference of the inner surface of the tamper evidence feature (Figs. 1-8). 21. The polyester resin closure of claim 1, wherein the tamper evidence feature comprises a lower wall and a folded band configured to fold behind the lower wall and under the tamper evidence ledge of the finish (Figs. 1-8). 22. The polyester resin closure of claim 21, wherein the lower wall is connected to a bottom of the outer cylindrical wall by way of a plurality of space-apart bridges (Figs. 1-8). 23. The polyester resin closure of claim 22, wherein the spaced-apart bridges are configured to break when the closure is unthreaded from the finish such that the folded band is retained in position by the tamper evidence ledge (Figs. 1-8). 24. The polyester resin closure of claim 22, wherein one or more of the bridges are configured to withstand a greater breaking stress than the breaking stress of remaining bridges such that the one or more bridges remain intact to provide a tether to keep the closure attached to the finish (Figs. 1-8).
