Description

  The present invention relates to a blister packaging sheet for packaging tablets (hereinafter referred to as “PTP sheet”) and a manufacturing apparatus thereof.

  The PTP sheet is composed of a packaging film in which a pocket portion for accommodating a tablet is formed and a cover film attached to the packaging film so as to seal the opening side of the pocket portion. In general, the packaging film is formed of a transparent resin or the like, and the cover film is formed of an opaque material such as aluminum. Furthermore, in recent years, a technique for forming a packaging film with an opaque material such as aluminum has been proposed from the viewpoint of improving light shielding properties and moisture proof properties (see, for example, Patent Document 1).

  By the way, in the PTP sheet in which both the packaging film and the cover film are formed of an opaque material as described above, the tablets contained therein cannot be visually recognized. Therefore, after taking out each tablet from a plurality of PTP sheets, there is a possibility that it cannot be confirmed from which PTP sheet a certain tablet is taken out.

  For example, when two types of tablets a and b are taken in different numbers (for example, 1 for a and 2 for b), PTP sheet A in which tablet a is contained and the inside cannot be seen, and tablet b Is taken from the PTP sheet B in which the inside of the PTP sheet B is not visible, and those who take tablets take out the required number of tablets (for example, one from one PTP sheet and two from the other PTP sheet). Here, if the tablet in the PTP sheet is visible by forming the packaging film with a transparent material or the like, which PTP sheet the extracted tablet is extracted from, that is, It can be confirmed whether the tablet is a or b. However, in the PTP sheet in which the tablet cannot be visually confirmed, it cannot be confirmed from which PTP sheet the extracted tablet is extracted. That is, it cannot be confirmed that the two extracted tablets are tablets a, and it cannot be confirmed that the one extracted tablet is tablets b. Therefore, there is a possibility that a situation such as accidentally taking a tablet different from the tablet to be originally taken may occur.

  Therefore, it is conceivable that it is possible to confirm whether or not the taken-out tablet and the tablet accommodated in the PTP sheet coincide with each other by providing a character display indicating the type of the tablet on the PTP sheet. (For example, see Patent Document 2).

JP 2007-118978 A JP 2007-223625 A

  However, the character display shown on the PTP sheet is the name of the tablet, etc., and if the person has little knowledge about the tablet, etc., whether the taken-out tablet and the tablet contained in the PTP sheet match. It is difficult to confirm.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to take out a tablet even if the packaging film and the cover film are each formed of an opaque material and the contained tablet is invisible. It is in providing the PTP sheet which can confirm easily whether the tablet accommodated and it accommodates, and its manufacturing method.

  According to the means 1, both the packaging film and the cover film are formed of an opaque material. Therefore, while it is possible to improve the light-shielding property and moisture-proof property, it is difficult to confirm whether or not the taken-out tablet and the tablet accommodated in the PTP sheet match.

  In this regard, according to the means 1, the tablet display portion having a photograph or a picture showing the appearance of the tablet is printed on the PTP sheet. Therefore, even a person who lacks knowledge about tablets can easily confirm whether the taken-out tablets and the tablets stored in the PTP sheet match based on the tablet display unit. it can. As a result, it is possible to more reliably prevent a situation such as accidentally taking a tablet different from the tablet to be originally taken.

  In addition, when a tablet different from the tablet that should be originally stored is erroneously stored in the PTP sheet, it may be recognized based on the tablet display section that the incorrect tablet is stored. it can. As a result, the wrong tablet can be more reliably prevented.

  The “tablet display unit” does not necessarily indicate the shape and color of the tablet, but may indicate only the shape of the tablet.
