Abstract

A radio frequency identification (RFID)-enabled article includes a body formed of a plastic or other polymeric first material having at least one wall, the wall having a length, a width, and a thickness, and wherein the thickness dimension is smaller than the length and the width and is defined between a first surface and a second surface; and an RFID transponder embedded 5-95% into the thickness dimension of the wall. The first and second surfaces of the wall are free from witness marks.

First claim

1 . A method of making an article having an embedded identifier, the method comprising the steps of:
forming a body of a plastic or other polymeric first material having at least one wall, the wall having a preassembly thickness in a thickness dimension defined between a first surface and a second surface; placing an identifier on the second surface of the wall; and encapsulating the identifier by overmolding a plastic or other polymeric second material which may be the same as or different from the first material onto the second surface and the identifier, forming a monolithic wall having a new thickness dimension defined between the first surface and a new second surface, the new thickness being thicker than the preassembly thickness.

2 . The method of claim 1 , wherein the embedded identifier is a radio frequency identification (RFID) transponder.

3 . The method of claim 1 , wherein forming the body step includes injection molding the plastic or other polymeric first material.

4 . The method of claim 1 , wherein forming the body step includes decreasing an initial thickness to the preassembly thickness by machining the second surface of the wall.

5 . The method of claim 1 , wherein the forming the body step includes injection molding the plastic or other polymeric first material into a first cavity having a cavity geometry, and wherein the encapsulating step includes injection molding the plastic or other polymeric second material into the first cavity or a second cavity having the same cavity geometry as the first cavity.

6 . The method of claim 1 , further comprising expanding the body by heating before the encapsulating step.

7 . The method of claim 1 , wherein the new second surface comprises an exterior surface of the article.

8 . The method of claim 1 , wherein the forming the body step includes injection molding the plastic or other polymeric first material into a first cavity having a cavity geometry, and wherein the encapsulating step includes injection molding the plastic or other polymeric second material into a second cavity having a cavity geometry larger than the cavity geometry of the first cavity.

9 . The method of claim 1 , wherein the step of encapsulating the identifier by overmolding includes encapsulating the identifier by dip coating the body.

10 . An article formed by the method of claim 1 .

11 . A method of making an article with an embedded identifier, the method comprising the steps of:
closing a mold having a first cavity with a first geometry and a second cavity with a second geometry, the first cavity closing around a first mold core; injecting into the first cavity a plastic or other polymeric first material to form a first body having at least one wall; opening the mold to expose the first body; placing an identifier on a surface of the wall; repositioning the first body and first core with respect to the mold; closing the mold with the first cavity around a second core and the second cavity around the first core; and simultaneously injecting into the first cavity a plastic or other polymeric second material, which may be the same as or different from the first material, to form a second body having at least one wall, and injecting into the second cavity a plastic or other polymeric third material, which may be the same as or different from the first and/or second material, to encapsulate the identifier by overmolding the third material onto the second surface and the identifier, wherein the second geometry is larger than the first geometry.

12 . The method of claim 11 , wherein the embedded identifier is a radio frequency identification (RFID) transponder.

13 . An article formed by the method of claim 11 .

14 . A radio frequency identification (RFID)-enabled article, the article comprising:
a body formed of a plastic or other polymeric first material having at least one wall, the wall having a length, a width, and a thickness, and wherein the thickness dimension is smaller than the length and the width and is defined between a first surface and a second surface; and an RFID transponder embedded 5-95% into the thickness dimension of the wall, wherein the first and second surfaces of the wall are substantially free from witness marks.

15 . The article of claim 11 , wherein the first and second surfaces or the wall are free from witness marks.

16 . The article of claim 11 , wherein the RFID transponder is disposed in the wall and has a length, a width, and a thickness, and wherein the thickness of the RFID transponder is smaller than the length and width of the RFID transponder, and therein the RFID transponder is disposed such that the thickness of the RFID transponder is parallel to the thickness dimension of the wall.

17 . The article of claim 11 , wherein the RFID transponder is covered by a layer formed of a plastic or other polymeric second material which may the same as or different from the first material.

18 . The article of claim 11 , wherein the first surface comprises an exterior surface of the article, and the second surface comprises an interior surface of the article.

19 . (canceled)

20 . The article of claim 11 , wherein the wall is a side wall surrounding an inner cavity of the article.

21 . (canceled)

22 . The article of claim 11 , wherein the article is a cryogenic vial.

23 . (canceled)

24 . (canceled)
