Description

In order to increase the reading distance of the data of the PTP sheet packaged with multiple tablets of 920 MHz RFID in the UHF band that can be made invisible for counterfeit prevention and product management of PTP (press through pack) of pharmaceuticals, The present invention relates to a PTP with RFID, characterized in that a part thereof is punched out or a sheet material is molded and an RFID is attached.

Counterfeit medicines are on the market, and taking them incorrectly can harm your health. Various techniques are used for anti-counterfeiting. RFID UHF and NFC are also being used, and are also used in the pharmaceutical and medical fields. Although some cases of using RFID for PTP have been proposed, the spread is still low. For popularization, there is a demand for a method that is less expensive and easier to manufacture.

There is a desire for a PTP with RFID that is easier to manufacture, has a longer reading distance, and is easier to handle. PTP is a very rational packaging form and suitable for compact packaging of pharmaceuticals. As a result of intensive research and development of RFID-equipped PTP, which is anti-counterfeiting and easy to handle when dispensing, the present invention has been achieved.

Japanese Patent Application Laid-Open No. 2007-60407 WO2015/020042A1

Fiscal 2004 patent application technology trend survey report IC tag

In the technology disclosed in Japanese Patent Application Laid-Open No. 2007-60407, it is assumed that the wireless IC tag uses microwaves in the 2.45 GHz band. The length of the slot of the wireless IC tag is about 50 mm or about 25 mm. Therefore, the size of the impedance-matched inlet and space patterns can be relatively small. The use of aluminum foil as an antenna is widely known. In the prior patent WO2015/020042A1, the metal foil on the PTP sheet for packaging tablets, etc. is partially processed and used as an antenna for a wireless IC tag. It is an object of the present invention to provide a package with a wireless IC tag that can stably secure a sufficient communication distance even when the package is placed in a package containing a plurality of PTP sheets. It is stated that the object is to provide a package with a wireless IC tag that can communicate even when the wireless IC tag is attached.

In the patent document WO2015/020042A1, according to one embodiment, a metal sheet having a predetermined slot pattern formed thereon and a packaging part having a resin sheet, an IC chip, and power supply to the IC chip are described. an IC chip portion having an electrode member, and an end portion of the slot pattern is disposed in one corner region of the packaging portion. body is provided.

The present invention is a PTP having a structure in which a part of the aluminum foil of the UHF band RFID and a part of the antenna of the RFID are overlapped to increase the area of the antenna and extend the reading distance of the RFID, and a manufacturing method. .

The present invention utilizes a PTP aluminum foil as an RFID antenna. A 17 μm or 20 μm aluminum foil is used, and its composition is overcoat varnish (OP)/printing/aluminum foil/printing/heat sealing agent.

A sheet of PTP 1 in FIG. 1 contains a plurality of pharmaceutical tablets packaged as shown in FIG. 1 2 . The size of the PTP sheet varies depending on the size of tablets and the number of tablets per sheet. PTP sheets are used in consideration of the water vapor permeability required by PVC or PP (polypropylene), PVC/aclar film, and PVC/PVDC coatings of around 250 μm.

RFID can use 920 MHz in the UHF band, and an IC chip and an antenna are formed on a PET film with a thickness of about 50 μm. Aluminum foil is used for the antenna in terms of price.
The structure of RFID is a structure of PET film/antenna+IC chip/PET film/adhesive (adhesive).

A part of the RFID antenna and the aluminum foil of the PTP are overlapped and adhered via an adhesive agent, so that they are punched out as shown in 3 in FIG. A part of the RFID antenna in FIG. 3 is superimposed on that part. It becomes like 7 in FIG.

Instead of punching out the PTP sheet, the overlapped portion may not be punched out, but this portion may be molded to partially overlap the RFID antenna and the aluminum foil as shown in the cross section of the PTP shown in FIG.

At the time of PTP production, as shown in FIG. 6, molding, tablet filling, and aluminum foil sealing are performed side by side in two rows, and, for example, 10 tablets are punched into one sheet. At this time, the portion to which the RFID is attached is punched out at the same time, and the RFID is attached in-line or on a separate line according to the present invention.

As a result of the present invention, the RFID-equipped PTP can manage the product sheet by sheet, and the product name, manufacturing date, lot number, and expiration date can be confirmed by the RFID reader.

By linking product inventory management with RFID, it can also be used as a countermeasure against counterfeit medicines, preventing health hazards to patients.

By reading the RFID, it is possible to know where the drug was sold or to access public information on the drug by a doctor or caregiver using a reader, which is also useful for drug administration management.

CKD's FBP-300E PTP molding and filling machine uses PVC 250 μm as a molding sheet and aluminum foil 20 μm as an aluminum foil cover material with a predetermined printing and HS agent coating, and the tablets are packed at a punched sheet rate of 250 shots/minute. rice field. At this time, on both sides of the PVC sheet, as shown in FIG. 6, a portion for setting an RFID was cut out at the same time as one PTP sheet was cut out. After that, the RFID was set in the PTP on another line to manufacture the PTP with the RFID. At this time, the product name, manufacturing date, and manufacturing number were entered into the RFID. The input data was read on the same line to confirm that it was entered correctly.

Using CKD's PTP molding and filling machine, FBP-300E, as a molding sheet, double-sided aluminum type is used, filling and packaging is performed in the same way as [0019], RFID is set in PTP on the removed part on a separate line, and RFID is attached. of PTP was manufactured. At this time, the product name, manufacturing date, and manufacturing number were entered into the RFID. The input data was read on the same line to confirm that it was entered correctly.

The PTP sheet was manufactured by saving aluminum foil so that the aluminum foil lidding material of the PTP was not heat-sealed to a portion of the formed sheet. In this case, part of the antenna of the RFID tag was attached so as to overlap with the end face of the aluminum foil. A plan view is shown in FIG.

Paper or plastic film may be used as the cover material of PTP. Assuming this case, an aluminum foil of 15 μm was placed on a portion near the end surface of the paper or plastic film via an adhesive, and the RFID tag was attached thereon. The aluminum foil does not stick to 15 μm. Available thicknesses of 7-20 μm or even more are acceptable. As the adhesive, a strong tack adhesive used for packaging materials, or a dry lamination adhesive may be spot-applied for lamination. A labeler may be used to attach an aluminum foil laminate label to a predetermined position. A plan view is shown in FIG.

Paper or plastic film may be used as the cover material of PTP. Assuming this case, conductive ink containing silver was printed on paper or plastic film in an arbitrary width of 3 mm. The RFID tag was attached so that this part overlapped with a part of the antenna of the RFID tag. The ink used was Toyo Ink's RA FS FD 076, a UV curing ink with a low volumetric efficiency of 4×10 ⁻⁵ Ω·cm, but there are many similar inks that may be used. A plan view is shown in FIG.

Used PTP is collected in the hospital, or if the patient puts it in a predetermined collection box such as a pharmacy, PVC, aluminum foil, and RFID can be peeled off and sorted. RFIDs are difficult to disassemble and are incinerated to prevent malfunction during reuse, but PVC and aluminum foil can be recycled separately and reused. Separation of PVC and aluminum foil in PTP is in fact currently being done.

PTP with RFID has been proposed by each company in its own form. All of them can prevent forgery, confirm manufacture, and rewrite data. At the pharmacy, the data of the PTP sheets, for example, 5 sheets, and the UID ((Unique Item identification)) in the box can be read with a reader while the box is still in the box to confirm that the item is not missing or counterfeit.
