Attachment of an RFID tag to a container

Abstract

A container includes a container body having a sidewall and an end wall extending across the sidewall and closing an end of the container body. A retainer is received on the container body with a central portion of the retainer adjacent to the end wall of the container body and a flexible edge portion of the retainer engaging the sidewall of the container body at an angle to resist removal of the retainer away from the end wall. An RFID tag is disposed between the central portion of the retainer and the end wall of the container body. The retainer and the RFID tag may be disposed outside of the container body interior, but more preferably are disposed within the container body interior. The retainer preferably is imperforate, and the edge portion of the retainer preferably is in continuous peripheral contact with the container sidewall to seal the RFID tag from the container interior. In a preferred implementation, the container body is a molded plastic prescription vial having an annular sidewall, and the retainer is in continuous annular contact with the interior surface of the container sidewall to seal the RFID tag from the container interior.

Description

The present disclosure relates to a container, particularly a prescription vial, with an RFID tag attached to the container after fabrication of the container.

BACKGROUND AND SUMMARY OF THE DISCLOSURE

It has been proposed to place a radio frequency identification (RFID) tag on or in a wall of a container to confirm the genuineness of the package that includes the container and/or to provide other information concerning the package or a product within the package. A general object of the present disclosure is to provide a mechanism for attaching an RFID tag to a container, particularly a prescription vial, after fabrication of the container.

The present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.

A container in accordance with one aspect of the present disclosure includes a container body having a sidewall and an end wall extending across the sidewall and closing an end of the container body. A retainer is received on the container body with a central portion of the retainer adjacent to the end wall of the container body and a flexible edge portion of the retainer engaging the sidewall of the container body at an angle to resist removal of the retainer away from the end wall. An RFID tag is disposed between the central portion of the retainer and the end wall of the container body. The retainer and the RFID tag may be disposed outside of the container body interior, but more preferably are disposed within the container body interior. The retainer preferably is imperforate, and the edge portion of the retainer preferably is in continuous peripheral contact with the container sidewall to seal the RFID tag from the container interior. In a preferred implementation, the container body is a molded plastic prescription vial having an annular sidewall, and the retainer is in continuous annular contact with the interior surface of the container sidewall to seal the RFID tag from the container interior.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 illustrates a package 10 in accordance with an exemplary embodiment of the present disclosure as including a closure 12 applied to the neck finish of a container 14. Container 14 includes a container body 16 that preferably is a prescription vial of molded plastic construction such as polypropylene. Container body 16 has an annular sidewall 18 that preferably is cylindrical or slightly conical, and an end wall 20 extending across sidewall 18 and closing one end of container body 16.

A retainer 22 is disposed within container body 16 in the embodiment of FIGS. 1-2. Retainer 22 preferably is of one-piece molded plastic construction such as polyethylene. Retainer 22 preferably has a domed central portion 24, and a flexible peripheral edge portion 26 integral with and at an angle to central portion 24. In the preferred implementation in combination with annular container bodies 16, central retainer portion 24 is circular and flexible peripheral edge portion 26 is annular. Retainer 22 is inserted into container body 16 such that retainer edge portion 26 is in annular contact with the inside surface of container sidewall 18 and central portion 24 is adjacent to container body end wall 20.

An RFID inlay 28 is disposed between retainer 22 and container end wall 20. Inlay 28 preferably includes an RFID tag 30 electrically connected to an antenna 32, with both being disposed on a substrate 34. An annular wall 36 on retainer 22 engages container end wall 20 and captures inlay 28 between retainer 22 and end wall 20. Friction fit between retainer edge portion 26 and the opposing inside surface of container sidewall 18 holds retainer 22 and RFID inlay 28 in position within container body 16. Retainer 22 preferably is imperforate so that RFID inlay 28 is sealed from the interior of container body 16. A particular advantage of the present disclosure is that retainer 22 and inlay 28 can be employed in conjunction with existing designs of container body 16 without any modification to the existing container body. However, a segmented or continuous internal bead 38 can be provided on container body sidewall 18 at a position spaced from end wall 20 for engagement by retainer edge portion 26 to enhance capture of retainer 22 and inlay 28 within the container body.

RFID tag 30 and inlay 28 can be loosely captured between retainer 22 and container end wall 20. Inlay 28 and RFID tag 30 could be adhered to the concave interior of retainer central portion 24 or molded into retainer central portion 24 as illustrated in FIG. 3.

FIG. 6 illustrates a container 40 in accordance with a second exemplary embodiment of the present disclosure as including a container body 16 in which the sidewall 18 extends beyond end wall 20 to form a cavity 42 beneath end wall 20. Retainer 22 and inlay 28 can be disposed within cavity 42, with container edge portion 26 in angled frictional contact with the inside surface of the container sidewall extension. The embodiment of FIG. 6 has the advantage that the retainer and the RFID tag (and inlay) are disposed outside of the container interior so that no issues are presented relative to the materials of the retainer and the inlay in contact with the product within the container.

There thus has been disclosed a container with attached RFID tag that fully satisfies all of the objects and aims previously set forth. The disclosure has been presented in conjunction with exemplary embodiments, and additional modifications and variations have been discussed. Other modifications and variations readily will suggest themselves to persons of ordinary skill in the art in view of the foregoing description. The disclosure is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
