Description

  The present invention relates to a medical container with RFID in which an RFID is provided in a medical container such as an ampoule.

Due to remarkable progress in IT technology in recent years, RFID (Radio Frequency Identification) equipped with ultra-small IC chips has come to be used for management of product manufacturing, quality, distribution, etc. instead of barcodes. . By appropriately recording product information (product name, lot number, production date, quality retention period, etc.) and receipt / shipment information (shipping date, receipt date, etc.) etc. on this RFID, the product manufacturer passes the distributor to the consumer. Merchandise management including distribution history up to each can be performed for each product.
If such a RFID is provided in a medical container, pharmaceutical management can be performed accurately and easily. For example, at each distribution base from the manufacturer through distributors to consumers (medical workers, patients, etc.), desired information such as receipt / shipment information (shipping date, warehousing date, etc.) and inspection information is stored in RFID. By adding or updating records, it is possible to keep a very accurate distribution history of the medicine.

  As a means for providing RFID, for example, in Patent Document 1, an antenna pattern made of conductive ink is printed on a cylindrical label substrate surface, and an IC tag is pasted so as to be electrically connected to the antenna pattern. It is disclosed that a bottle label with an IC tag attached is attached to a container body.

However, when an RFID is attached to the container body, the RFID is bent and deformed along the shape of the container body. When the RFID is deformed in this way, communication with a wireless communication device such as a reader device is deteriorated, and the reading sensitivity of information on the RFID is lowered.
In addition, there is a risk that the RFID may be damaged by rubbing or colliding with each other on the production line or during storage and transportation.

  Therefore, the present inventors studied to apply an adhesive to the RFID to form a tack label and affix it to the bottom surface of the medical container. However, many medical containers such as ampoules have a relatively small bottom surface, and the bottom surface is not flat but recessed, so that RFID may drop from the bottom surface during distribution storage. .

In view of the above points, a heat-shrinkable tubular film obtained by forming a heat-shrinkable film into a cylindrical shape was also examined, and RFID was held by the film.
Specifically, after attaching an RFID in the form of a tack label to the bottom surface of a medical container, heat shrinkage is applied to the container body while aligning so that the upper end portion of the heat-shrinkable tubular film protrudes from the bottom surface of the container. An external tubular film is externally fitted and thermally contracted. In the obtained medical container with RFID, the lower end portion of the tubular film is in close contact with the body portion of the container, and the upper end portion of the tubular film is bent toward the bottom side of the container and covers the peripheral portion of the RFID. Hold. Such a medical container with RFID can prevent the RFID from falling off by holding a cylindrical film.

However, when a heat-shrinkable tubular film formed in a cylindrical shape is used as the RFID holding means, a mounting device (shrink device) having a positioning mechanism is used when the tubular film is externally fitted to a container. There must be.
Specifically, the tubular film is formed to have a larger diameter than the body portion of the container in order to be externally fitted to the body portion of the container. Therefore, it is necessary to stop the externally fitted tubular film at a predetermined position of the container until the tubular film is heated. For this reason, when mounting | wearing a heat-shrinkable cylindrical film, you have to use the mounting apparatus which has a positioning mechanism holding the external fitting position of a cylindrical film.
Generally, a mounting apparatus having this positioning mechanism is complicated and large in size. For this reason, there is a problem in that the production cost increases in the mechanical manufacture of the medical container with RFID. In particular, when RFID medical containers are produced in a small lot and in a wide variety, the positioning mechanism must be adjusted or changed in accordance with the type and shape of the container, which further increases the cost.

Japanese Patent Laid-Open No. 2004-20771

  Therefore, the present invention provides a medical container with an RFID that can be held so that the RFID does not fall off and can be manufactured at a relatively low cost.

In order to solve the above problems, the present invention includes a medical container having an RFID attached to an end surface thereof and a heat-shrinkable film having an adhesive on the back surface, and the heat-shrinkable film is wound around the medical container. An RFID-equipped medical container in which an end portion of the heat-shrinkable film is bent toward the end face side of the medical container by heat shrinkage and covers at least a peripheral portion of the RFID is provided.
Examples of the medical container include ampules, vials, and prefilled syringes.

Since the RFID-equipped medical container is attached to the end face of the medical container, the end of the heat-shrinkable film is bent to the end face side of the medical container by heat shrinkage and covers at least the peripheral part of the RFID. RFID is held by the heat-shrinkable film. Therefore, it is possible to provide a medical container with an RFID, in which the RFID does not easily drop from the container end surface.
In addition, since the edge of the heat-shrinkable film covers the peripheral edge of the RFID, when the medical container is faced with the end face down, the surface of the RFID is directly on the loading surface such as a conveyor. It becomes difficult to touch. Therefore, the RFID can be prevented from being damaged during distribution storage.
Furthermore, since the heat-shrinkable film has an adhesive on the back surface, when the heat-shrinkable film is wound around the medical container, the heat-shrinkable film is maintained in a wound state via the adhesive. Therefore, even if the mounting apparatus does not have a positioning mechanism, the heat-shrinkable film can be heat-shrink mounted at a predetermined position.

  In a preferred aspect of the present invention, the medical container has a cylindrical body part for storing a medicine and a bottom surface continuing to the body part, the RFID is attached to the bottom surface of the medical container, and the heat shrinkability Provided is the medical container with RFID, in which a heat-shrinkable film is wound around the trunk of the medical container so that the main stretching direction of the film is the circumferential direction of the medical container.

In the medical container with RFID, the heat-shrinkable film is wound around the body of the medical container via an adhesive, and the end of the heat-shrinkable film is bent to the bottom surface side of the medical container by heat shrinkage. It covers at least the peripheral edge of the RFID.
When the end of the heat-shrinkable film is heat-shrinked and bent, the entire heat-shrinkable film may be heated. However, since the whole heating may cause heat to be applied to the medicine in the container, mainly only the end. Is preferably heated locally.
That is, in the present invention, since the heat-shrinkable film provided with the adhesive is wrapped around the body of the medical container, it is not always necessary to heat the entire film, and only the end is locally heated to attach the RFID. A medical container can be obtained. Since the RFID-equipped medical container has RFID attached to the bottom surface of the container, when the end portion is locally heated to thermally contract the end portion of the heat-shrinkable film, the heat is applied to the bottom surface of the container. Only a little added. For this reason, the medical container with RFID can be manufactured without causing deterioration of the quality of the stored medicine.

In a preferred embodiment of the present invention, there is provided the medical container with RFID, wherein at least one of a printed layer or a top coat layer made of ultraviolet curable ink is applied to the surface side of the heat shrinkable film.
Such a heat-shrinkable film can be improved in adhesiveness between the heat-shrinkable film and the container because the end of the heat-shrinkable film is easily bent toward the container when the end is bent by heat-shrinking.

  The medical container with RFID is used for distribution as it is or in a state of being wrapped by a packaging material such as an assembly box. When packaging with a packaging material, one or more medical containers with RFID can be packaged together. When packaging a plurality of medical containers with RFID, the medical containers with RFID are preferably packaged with a packaging material with the RFID provided in each container facing one side.

The medical container with RFID of the present invention can prevent the RFID attached to the end face from dropping off. In addition, since the medical container with RFID of the present invention can be manufactured by a mounting device that does not have a positioning mechanism, it can be manufactured at a relatively low cost and can cope with small-lot production.
Furthermore, the medical container with RFID according to the present invention can be manufactured without deteriorating the quality of the stored medicine according to its preferred mode.

Hereinafter, the present invention will be specifically described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a medical container 2, an RFID 3 attached to the end face of the medical container 2, and a heat shrink with an adhesive attached to the medical container 2 to hold the RFID 3. The medical container with RFID which has the adhesive film 5 is shown.
In the medical container 1 with RFID, the end portion 5a of the heat-shrinkable film 5 wound around the medical container 2 in a cylindrical shape is bent to the end surface side of the medical container 2 by heat shrinkage, and at least the periphery of the RFID 3 This is covered with the portion 3a.

The medical container 2 is not specifically limited, A well-known thing can be used. The medical container 2 illustrated in FIG. 1 is an ampoule in which a medicine is enclosed. An ampule is a medical container that can be partially broken to take out a pharmaceutical product.
The ampoule 2 includes, for example, a substantially circular bottom 21 in plan view, a cylindrical body 22 following the bottom 21, a small-diameter sealing part 23 following the body 22, a body 22 and a sealing part 23. It is the container which has the bend part 24 formed between these. The bottom surface 21 of the ampoule 2 is a surface portion that is substantially orthogonal to the axial length direction of the body portion 22, and the ampoule 2 can be made independent with the bottom surface 21 facing down.
In addition, the ampule 2 can use a well-known thing, The thing made from glass, a synthetic resin etc. can be used for the material, for example.

  An RFID 3 is attached to the bottom surface 21 (end surface) of the medical container 2 (ampoule). For example, the RFID 3 is provided with a pressure-sensitive adhesive (or adhesive) on one surface of the support base (the surface on which the module unit is not provided), and is attached to the medical container 2 through the pressure-sensitive adhesive. Attached to the bottom surface 21. However, since the RFID 3 is held by the heat-shrinkable film 5, it may be simply attached to the bottom surface 21 of the medical container 2 in a non-adhered state without interposing an adhesive or the like.

The RFID 3 has at least a module unit including an IC chip and an antenna unit, and is electrically connected to the IC chip in a non-contact manner by a wireless communication device (which may be a read type, a write type, or a read / write type as will be described later). A wireless electronic component that can read information and / or write information to an IC chip, and known devices can be used in the present invention.
Note that the RFID 3 generally includes those expressed as an RFID tag, an RFID inlet, an IC tag, a wireless IC tag, a non-contact IC, a non-contact data carrier, and the like.
In general, the RFID 3 is put to practical use in which the module unit is provided on the support base material 33. Specifically, for example, as shown in FIG. 2, the RFID 3 has a module part composed of an IC chip 31 and an antenna part 32 formed on the surface of a support base 33, and a protective layer 34 is laminated thereon. Can be illustrated. However, the RFID 3 without the protective layer 4 can also be used.
As the support base material 33 and the protective layer 34, a known synthetic resin sheet, resin injection molded product, or the like can be used.

The planar shape (the shape including the support base material 33) of the RFID 3 is not particularly limited, but a shape that fits in the bottom surface 21 is preferable so that it does not protrude outward from the bottom surface 21 of the medical container 2. This is because if the size is larger than the bottom surface 21, when the heat-shrinkable film 5 is attached, a part of the RFID 3 is bent toward the container body 22, and in some cases, the function of the RFID 3 may be impaired. Specifically, as the shape of the RFID 3, for example, it is preferable to use one having substantially the same shape and size as the bottom surface 21 of the medical container 2 or having a smaller area than the bottom surface 21. 2 having the same shape and size as the bottom surface 21 is preferable. This is because, when the end portion 5a of the heat-shrinkable film 5 is bent, the end portion 5a reliably covers the peripheral portion 3a of the RFID 3 within a sufficient range.
Although the thickness of RFID3 is not specifically limited, Usually, the thing of about 100 micrometers-2 mm is used.

The heat-shrinkable film 5 has a rectangular heat-shrinkable base 51 and an adhesive 52 provided on the back surface of the base 51, and if necessary, design printing (not shown). Or metal vapor deposition may be applied to the substrate 51.
The printing layer is preferably applied to the surface side of the substrate 51, and it is preferable to use an ultraviolet curable ink as the printing ink. Note that an ultraviolet curable top coat layer (clear varnish) may be applied to the outermost surface of the substrate 51.
As described above, by providing a printing layer and / or a topcoat layer on the surface side of the substrate 51, the tip of the heat-shrinkable film 5 is curved toward the container side, and the film 5 and the container 2 at the tip. Adhesion can be improved.
The heat-shrinkable substrate 51 is not particularly limited, and examples thereof include styrene resins such as polystyrene, polyester resins such as polyethylene terephthalate, olefin resins such as polypropylene and cyclic olefin, polycarbonate, and vinyl chloride resins. A film containing one kind selected from these thermoplastic resins or a mixture of two or more kinds can be used. The substrate 51 may be a laminated film in which two or more kinds of films having heat shrinkability are laminated. The film can be provided with heat shrinkability by forming and stretching the film by a known production method. The stretching treatment is usually performed by stretching at a temperature of about 70 to 110 ° C. in the longitudinal direction (MD direction) by 2.0 to 8.0 times, preferably about 3.0 to 7.0 times. Furthermore, you may perform a extending | stretching process by the low magnification of 1.5 times or less also in the width direction (TD direction), for example. The obtained film becomes a uniaxially stretched film or a biaxially stretched film slightly stretched in a direction orthogonal to the main stretch direction. The thickness of the film is preferably about 20 to 60 μm.
The heat-shrinkable film 5 is wound around the medical container 2 such that the main stretching direction (MD direction) of the base material 51 is the circumferential direction of the medical container 2.

The heat shrinkage rate of the base material 51 is not particularly limited as long as it can be heat-shrinkable to the extent that it can be closely attached to the RFID 3, but usually the heat shrinkage rate in the longitudinal direction (MD direction) (90 ° C. warm water). For 10 seconds) is about 30% or more, preferably about 40% or more. Moreover, the thermal contraction rate (immersion for 10 seconds in 90 degreeC warm water) in the width direction of the base material 51 is about about -3 to 15%.
However, heat shrinkage rate (%) = [{(original length in the longitudinal direction (or width direction)) − (length after immersion in the longitudinal direction (or width direction))} / (longitudinal direction (or width direction) ) Original length)] × 100.

The adhesive 52 is not particularly limited as long as it has an adhesive force that can adhere the heat-shrinkable film 5 to the medical container 2. The adhesive 52 is meant to include what is generally called a pressure-sensitive adhesive (a material that can be peeled off by hand or a material that has a pressure-sensitive adhesive force that can be reapplied after peeling). As the adhesive, for example, a heat-sensitive adhesive, a pressure-sensitive adhesive, or the like can be used.
The adhesive 52 is laminated on the back surface of the heat-shrinkable base material 51 and temporarily attached on the release paper. The obtained heat-shrinkable film 5 with adhesive is loaded on, for example, a tack labeler, and is wound around the container body 22 while peeling the release paper.
When a heat-sensitive adhesive is used, a release paper is not necessary, and therefore it is preferable to use a heat-sensitive adhesive as the adhesive 52. The heat-sensitive adhesive is an adhesive that does not exhibit adhesiveness at room temperature and can exhibit adhesiveness when heated. As such a heat-sensitive adhesive, for example, a hot-melt adhesive, a part coat heat-sensitive adhesive, a delayed tack heat-sensitive adhesive, or the like can be appropriately used.

The hot-melt adhesive does not exhibit adhesiveness at room temperature, and can be bonded by heating, and is an adhesive that can be applied by heating and melting.
The part coat type heat-sensitive adhesive does not show adhesiveness at room temperature but shows adhesiveness by heating, and is a hot melt adhesive applied in a solution state. Part-coat type heat-sensitive adhesive can be applied by printing such as gravure coating with a solution in which a heat-adhesive resin such as ethylene-vinyl acetate copolymer and a tackifier are dissolved or dispersed in an organic solvent. It is used after drying after coating.
A delayed tack-type heat-sensitive adhesive does not exhibit adhesiveness at room temperature, is activated by heating to exhibit adhesiveness, and persists for a long time after cooling, and is applied by printing such as gravure coating. It is a workable adhesive.

  The adhesive 52 is provided in a solid form on the entire back surface of the heat-shrinkable substrate 51. However, the adhesive 52 may be provided at least on both side edges 5b and 5c of the base material 51 (the adhesion start side edge and the adhesion completion side edge when wound around the container 2). As a means for making it possible to bond at both side ends 5b, 5c of the heat-shrinkable film 5, (A) the adhesive 52 is applied to the side edges 5b, 5c of the base material 51 in the form of upper and lower bands. (B) An adhesive 52 is provided on the entire back surface of the base material 51, and a masking process (for example, an ultraviolet curable type) is performed on a central region of the exposed surface of the adhesive 52 excluding both end portions 5b and 5c of the base material 51. For example, a method of applying a masking agent such as ink) is exemplified.

  The heat-shrinkable film 5 has its end portion 5a protruding outward from the bottom surface 21 of the medical container 2 and is wound around the trunk portion. The protruding end portion 5a is heat-shrinked and the surface peripheral edge portion 3a of the RFID 3 is wound. Is in close contact. Therefore, the edge portion 5a of the heat-shrinkable film 5 that is bent covers the surface peripheral edge portion 3a of the RFID 3.

The RFID-equipped medical container 1 can be manufactured, for example, by the following procedure.
The RFID 3 is attached to the bottom surface 21 of the medical container 2. At this time, an adhesive (or adhesive) is provided on one surface of the RFID 3 (for example, the surface side where the module portion of the support base material 33 is not provided), and the RFID 3 is medically treated through the adhesive (or adhesive). It is preferable to stick to the bottom surface 21 of the container 2 for use.
Next, as shown in FIG. 3A, the end portion 5a of the heat-shrinkable film 5 is positioned so as to protrude outward from the bottom surface 21 of the container 2, and one end portion 5b of the heat-shrinkable film 5 is placed. Is attached along the axial length direction of the body portion 22 of the medical container 2.
When the heat-shrinkable film 5 having the heat-sensitive adhesive coated on the back surface is used as the adhesive 52, the heat-sensitive adhesive is heated to be in a state where it can be bonded immediately before winding. It is also possible to use a heat-shrinkable film on which the adhesive 52 has not been applied in advance. In this case, the adhesive 52 is applied to the entire back surface (or a predetermined position) of the heat-shrinkable film 5 just before winding. What is necessary is just to apply.

  And after winding this heat-shrinkable film 5 around the trunk | drum 22 of the medical container 2, as shown in FIG.3 (b), the back surface of the other side edge part 5c of the heat-shrinkable film 5 is made into one side end. Adhere to the surface of the part 5b. As described above, the heat-shrinkable film 5 is wound around the container body portion 22 in a cylindrical shape, and the cylindrical end portion 5 a protrudes outward from the bottom surface 21 of the medical container 2.

Then, by heating the end portion 5a of the heat-shrinkable film 5 projecting outward, the end portion 5a is thermally contracted and bent inward, and is in close contact with the peripheral portion 3a of the RFID 3 attached to the container bottom surface 21. To do.
In heating, it is preferable to locally heat only the end 5a so that heat is mainly applied to the protruding end 5a of the heat-shrinkable film 5. This is because, when the container 2 is heated as a whole, the medicine in the container 2 may be heated, but depending on the kind of the medicine, the quality may be deteriorated by the heat. In the present invention, since the heat-shrinkable film 5 provided with the adhesive 52 is wound around the body portion 22 of the medical container 2, the region corresponding to the container body portion of the heat-shrinkable film 5 does not heat-shrink. The local heating can be performed without hindering the mounting. Therefore, the RFID 3 holding structure by the heat-shrinkable film 5 of the present invention is particularly suitable for the medical container 2.
The heating method can be performed by a known method such as hot air at 100 to 250 ° C. or steam, but it is preferable to use hot air because it can be heated locally.
Moreover, when the heat-shrinkable film 5 in which the printing layer and / or topcoat layer are given to the surface side of the base material 51 is used, when the end portion 5a is heated, the end portion 5a becomes the container bottom surface 21. While bending to the side, the tip of the end portion 5a is bent to the container bottom surface 21 side. Accordingly, since the tip of the heat-shrinkable film 5 is in close contact with the container bottom surface 21, foreign matter is caught between the tip of the heat-shrinkable film 5 and the container bottom surface 21, or the tip of the heat-shrinkable film 5 is caught. Can be prevented.

The RFID-equipped medical container 1 has the RFID 3 attached to the bottom surface 21 of the medical container 2, the end portion 5a of the heat-shrinkable film 5 bends toward the bottom surface 21 of the medical container 2 due to heat shrinkage, and at least the surface of the RFID 3 Since the peripheral edge portion 3a is held, the RFID 3 can be prevented from falling off from the container bottom surface 21.
Moreover, since the edge part 5a of the heat-shrinkable film 5 has covered the surface peripheral part 3a of RFID3, this edge part 5a also has a function as a protection part of RFID3. That is, when the medical container 1 with RFID is self-supported with the bottom surface 21 facing down, the end portion 5a of the heat-shrinkable film 5 that covers the RFID 3 is in contact with the mounting surface, so that the surface of the RFID 3 is mounted. It becomes difficult to touch the surface directly. Therefore, it is possible to prevent the RFID 3 from being damaged during distribution storage.
Further, since the heat-shrinkable film 5 has the adhesive 52 on the back surface, when the heat-shrinkable film 5 is wound around the medical container 2, the heat-shrinkable film 5 is wound through the adhesive 52. State is maintained. Therefore, even if the mounting apparatus does not have a positioning mechanism, the heat-shrinkable film 5 can be heat-shrink mounted at a predetermined position.

The above-mentioned medical container 1 with RFID can be provided on the market by individually packaging it in a packaging material such as an assembly box, but is usually provided in the form of a package in which a plurality of the medical containers 1 are packaged with the packaging material. The
FIG. 4 shows an example of the package 10.
The package 10 includes a packaging material 11 and a plurality of RFID-equipped medical containers 1 housed inside the packaging material 11, and each RFID-equipped medical container 1 has an end surface to which the RFID 3 is attached ( Are arranged in a state where the bottom surface is directed to one surface side of the packaging material 11.
The packaging material 11 is not particularly limited, and for example, an assembly box in which relatively hard sheets such as cardboard, cardboard, and hard plastic sheet are assembled can be used. The packaging material 11 may be either non-transparent or transparent.
The number of RFID-equipped medical containers 1 packaged by the packaging material 11 is not particularly limited as long as it is plural (two or more). Further, the arrangement of the medical containers 1 with RFIDs is not particularly limited as long as the RFIDs 3 are directed to one surface side of the packaging material 11. For example, the medical containers 1 with RFIDs can be arranged in a multi-tiered manner.
Reference numeral 12 denotes a corrugated cushioning sheet (rondration) provided in the packaging material 11 (not shown in FIG. 4A).

Next, the manufacturing method of the said package 10 and the RFID communication method of the package 10 are demonstrated.
The medicine 3 is filled with the medicine, and the RFID 3 in which the information related to the medicine (desired information such as the product name, the individual identification number of the medicine, the manufacturing date, the manufacturing place, the quality retention time) is prepared. The RFID-equipped medical container 1 is manufactured using the RFID 3 according to the above procedure. Furthermore, a plurality of the RFID-equipped medical containers 1 are packed in the packaging material 11 to obtain the package 10.
It should be noted that recording of pharmaceutical information on the RFID 3 may be performed collectively or individually on each RFID 3 after the packaging body 10 is manufactured without being attached to the container 2.

The package 10 is transported by a transport line or the like, stored in a warehouse, or shipped from a manufacturer and used for distribution. Then, communication with the RFID 3 of each medical container 1 is performed in the state of the package 10 using a writable or readable / writable wireless communication device capable of writing information at a predetermined location such as a transport line. Is called.
For example, in the middle of this conveyance, a wireless communication device is disposed between the conveyors, and the wireless communication device is operated from one side of the package 10 conveyed by the conveyor, whereby the information recorded in the RFID 3 is respectively Information can be read and / or written to the RFID 3, respectively.
In addition, the wireless communication device is not limited to the mode in which the wireless communication device is arranged in the middle of transporting the package 10 and communicates with the RFID 3, and can communicate with the RFID 3 at a desired place.

Here, the wireless communication device is a device that can access the RFID 3 wirelessly (contactlessly), and is a read type that reads information from the RFID 3, a write type that records information in the RFID 3 wirelessly, or both the reading and writing. Any type of read / write type can be used.
In addition, the wireless communication device may be one that accesses each RFID 3 packaged in the package 10 or may be one that accesses a plurality of devices collectively.
Since the packaging body 10 has the RFIDs 3 of the plurality of medical containers with RFIDs 1 arranged on the one surface side of the packaging material 11, for example, one wireless communication device can communicate with the RFID 3.

  Next, the modification of this invention is shown. However, configurations and functions and effects different from those of the above embodiments will be mainly described, and descriptions of configurations and functions and effects similar to those of the above embodiments may be omitted, and terms and figure numbers may be used.

  In the said embodiment, although the heat shrinkable film 5 is wound so that the one side edge part 5b may overlap with the other side edge part 5c, as shown in FIG. You may wind so that 5b and the other side edge part 5c may not overlap. However, in this case, if the distance between the one side end portion 5b and the other side end portion 5c is too wide, the end portion 5a of the heat-shrinkable film 5 correspondingly corresponds to the peripheral portion 3a of the RFID 3. Since the covering length in the circumferential direction is shortened, it is preferable that the heat-shrinkable film 5 is wound to a degree exceeding half of the circumference of the body portion of the medical container 2.

Next, the medical container 1 with RFID according to the modification shown in FIG. 6 is provided with a cutting line 6 in the heat-shrinkable film 5 so that a part of the heat-shrinkable film 5 can be cut off and removed. Is. The cutting line 6 is formed in a range excluding the end 5a of the heat-shrinkable film 5 (the end bent to the peripheral edge 3a of the RFID 3) in the other end 5c of the heat-shrinkable film 5.
Examples of the cutting line 6 include perforations and half-cut lines. Moreover, as the adhesive 52 provided on the back surface of the heat-shrinkable film 5, it is preferable to use a pressure-sensitive adhesive that can be peeled off and attached again.
In the partitioned area 7 partitioned by the cutting line 6, for example, human-readable display in which drug information (for example, drug name, manufacturing lot, etc.) is represented as character information and / or the drug information is encoded. Printed mechanical readings (for example, one-dimensional codes such as barcodes and RSS (Reduced Space Symbology) codes, two-dimensional codes such as QR codes and data matrices, composite codes combining one-dimensional or two-dimensional codes, etc.) (Neither of these displays is shown). Reference numeral 7a denotes a knob extending from the edge of the partition region 7.
The medical container 1 with RFID according to the present modification can cut the partition region 7 by using the cutting line 6 and stick it to a desired part such as a syringe or a medical chart when using pharmaceuticals. Thus, since the division area 7 on which the drug information is displayed can be attached to a syringe or the like, it is possible to save the trouble of transcription and prevent a transcription mistake.

  Further, in the medical container 1 with RFID shown in FIG. 6, the other side end portion 5c is overlapped and wound around the surface of the one side end portion 5b of the heat shrinkable film 5. The same display as the display printed on the partition area 7 may be printed on the surface of the part 5 b and on the surface of the one side end 5 b corresponding to the partition area 7. Similarly to the above, the medical container 1 with RFID according to this modification can cut the partition area 7 using the cutting line 6 and paste it on a syringe or the like. Since the same display is printed thereunder, the display can be left on the RFID-equipped medical container 1 after cutting.

  An RFID-equipped medical container 1 according to the modification shown in FIG. 7 has a window 8 opened in a part of a heat-shrinkable film 5. By forming the window portion 8, the state of the medicine in the container 2 can be visually recognized from the outside. This modification is effective when the heat shrinkable film 5 is wound so that both end portions 5b and 5c overlap and the heat shrinkable film 5 is non-transparent (design printing is applied in a solid shape). Things).

Further, the medical container 1 with RFID according to the modification shown in FIG. 8 is wound with the other end portion 5c superimposed on the surface of the one end portion 5b of the heat-shrinkable film 5. The cutting line 6 is formed in a part of the overlapping region 5c. The above-described human reading display and / or mechanical reading display is printed in the partition area 7 partitioned by the cutting line 6 (the display is not shown). Moreover, as an adhesive agent of the heat-shrinkable film 5, it is preferable to use the adhesive which can be peeled and attached again.
A window portion 8 is formed in one side end portion 5 a on which the other side end portion 5 c is overlapped and corresponding to the partition region 7 defined by the cutting line 6.
In the medical container 1 with RFID, after the partition region 7 is cut out, the state of the medicine in the container can be visually recognized from the outside through the window portion 8.

Next, an example in which the present invention is applied to a small pharmaceutical container other than an ampoule, such as a vial or a prefilled syringe, will be described.
FIG. 9 shows an example in which the small medical container 2 is applied to a vial 2 ′. The vial bottle 2 ′ is a medical container in which a medicine is enclosed. The vial bottle 2 ′ includes, for example, a bottom surface 21 ′ having a substantially circular shape in plan view, a cylindrical body portion 22 ′ following the bottom surface, a shoulder portion 23 ′ gradually narrowing from the body portion 22 ′, and the shoulder portion. This is a container having an opening 24 ′ opened at the upper end of the portion 23 ′ and a lid 25 ′ such as a rubber plug for sealing the opening 24 ′. The bottom surface 21 ′ of the vial 2 ′ is a surface portion that is substantially orthogonal to the axial direction of the body 22 ′, and the vial 2 ′ can be self-supported with the bottom surface 21 ′ facing down.
The RFID 3 is attached to the bottom surface 21 ′ of the vial 2 ′, and the RFID 3 is held by the end portion 5 a of the heat-shrinkable film 5 as in the above embodiment.
The planar shape of the RFID 3 is not particularly limited, but is preferably substantially the same shape and size as the bottom surface 21 'of the vial 2' or smaller than the bottom surface 21 'and larger than the recessed portion. This is because if the RFID 3 is larger than the bottom surface 21 ′, the RFID 3 is bent when the heat-shrinkable film 5 is attached. On the other hand, the bottom surface 21 ′ of the vial 2 ′ is usually generally recessed at the center, so if the RFID 3 is too small than the bottom surface 21 ′, the RFID 3 will be in the recessed portion of the container bottom 21 ′. This is because the end portion 5 a of the heat-shrinkable film 5 that is fitted and bent cannot hold the peripheral edge portion 3 a of the RFID 3. Therefore, as shown in the figure, the RFID 3 is preferably attached so as to be in contact with the flat portion of the bottom surface 21 ′.

  FIG. 10 shows an example in which the prefilled syringe 2 ″ is applied as a small medical container 2. The prefilled syringe 2 ″ is an injection container in which a medicine is sealed in advance. The syringe 2 ″ includes a syringe body 24 ″ having a cylindrical body portion 22 ″ having an injection needle mounting portion 23 ″ formed at an end thereof, a plug body 25 ″ attached to the injection needle mounting portion 23 ″, And a piston rod part 27 ″ having a disc-like pressing part 26 ″ provided at the outer end thereof and inserted into the rear opening of the syringe body 24 ″. The pressing part 26 ″ of the piston rod part 27 ″. The end surface 21 ″ is a surface portion that is substantially orthogonal to the axial direction of the barrel portion 22 ″ of the syringe body 24 ″. The RFID 3 is attached to the end face 21 ″ of the pressing portion 26 ″. Further, the heat-shrinkable film 5 is wound around the pressing portion 26 ″ that constitutes a part of the syringe 2 ″, and the end portion 5a of the heat-shrinkable film 5 is heat-shrinked and bent, whereby the peripheral edge of the surface of the RFID 3 The part 3a is held.

  Both the medical container 1 with RFID of the vial 2 ′ and the medical container 1 with RFID of the prefilled syringe 2 ″ are packaged by packaging them in the packaging material 11 with the RFID 3 facing one side of the packaging material 11. The body 10 can be configured.
