Description

  The present invention belongs to a technical field related to a packaging structure of, for example, a medical device (such as a syringe) suitable for sterilization treatment and maintenance of sterilization.

Conventionally, as this type of packaging structure, techniques described in the following documents are known.
Japanese Patent No. 3376542

  As shown in FIG. 4, the technique disclosed in the patent document shows the entire inner surface of a cup-shaped enveloping body 2 made of a transparent synthetic resin film in which a flange 1 is extended outwardly on the periphery of an opening and a flange connected to the inner surface. A transparent adhesive layer 3 that exhibits adhesiveness by heating is provided over the entire surface, and is stretched and closed by an opaque sterilization treatment sheet 4 whose periphery is heat sealed to the flange 1 at the opening of the cup-shaped envelope 2. The container A in the cup-shaped enclosure 2 is hermetically held, and with this structure, the cleanliness (sterilization property) of the container A is strictly maintained, and the cup made of a transparent film The type of the contents A can be seen through from the outside through the shaped envelope.

  The adhesive layer 3 may be provided only on the flange 1. However, the adhesive layer 3 is formed on the entire surface of the developed resin film using a printing technique. It is easy, and therefore it is necessarily exposed to the portion of the adhesive layer 3 that is not heated and melted (heat-sealed), that is, the inner surface of the cup-shaped envelope 2. Since it does not exhibit the properties, it is a functionally meaningless exposure that does not give any problem to the contained object.

  Therefore, the present invention pays attention to the inner surface adhesive layer of the cup-shaped envelope 2 exposed insignificantly, and at first glance, the kind of the object that has not been proposed conventionally by using this adhesive layer. It is an object of the present invention to provide a packaging structure provided with an identification portion that can be clearly identified.

  In order to solve the above problems, the packaging structure according to the present invention employs the following means.

  That is, according to the first aspect of the present invention, the transparent surface that exhibits adhesiveness by heating is applied to the entire inner surface of the cup-shaped covering body made of a transparent synthetic resin film with the flange extending outwardly at the periphery of the opening and the entire surface of the flange that communicates with the inner surface The adhesive layer was provided, and the opening of the cup-shaped enclosure was stretched and closed with an opaque sheet whose periphery was heat-sealed to a flange, so that the contents contained in the cup-shaped enclosure were sealed and held. In the packaging structure, the container accommodated in the cup-shaped envelope is identified between the transparent synthetic resin film surface constituting the cup-shaped envelope and the transparent adhesive layer layered on the film surface. An identification unit is provided.

  With this means, since the identification part can be seen through the cup-shaped enclosure, the type of the contents in the cup-shaped enclosure can be confirmed at a glance, and an unexpected accident due to the misidentification of the contents can be avoided. Moreover, since the identification part is on the back side of the adhesive layer exposed in the cup-shaped envelope, the adhesive layer protects the identification part and can prevent the identification part from being damaged due to the sliding contact of the contents.

  According to a second aspect of the present invention, in the packaging structure of the first aspect, the identification part is formed by printing on a transparent synthetic resin film surface constituting the cup-shaped covering.

  With this means, the identification part can be printed simultaneously in the printing process when the adhesive layer is provided on the transparent synthetic resin sheet.

  According to a third aspect of the present invention, in the packaging structure of the first aspect, the transparent identification portion is a transparent colored printed layer.

  In this means, the transparent and transparent colored printed layers of the cup-shaped covering body overlap each other.

  According to a fourth aspect of the present invention, in the packaging structure of the third aspect, the transparent colored printed layer is formed on the entire surface of the transparent synthetic resin film constituting the cup-shaped envelope.

  In this means, the cup-shaped envelope including the flange and the whole perform the identification function.

According to the packaging structure according to the present invention, when the object contained in the transparent cup-shaped enclosure is viewed through the enclosure, the type of the object is reliably identified at a glance by the identification unit. In particular, when used for packaging medical devices, it can greatly help to avoid accidents.
In addition, since the transparent identification portion is on the back side of the adhesive layer exposed in the cup-shaped envelope and is protected by the adhesive layer, it is possible to prevent abrasion due to sliding contact with the object to be contained.

  According to the second aspect of the present invention, since the transparent identification portion can be formed simultaneously in the printing process when the adhesive layer is provided, there is an effect that the identification portion can be formed with good workability.

  Further, as described in claim 3, the objects to be accommodated can be reliably identified without hindering the existence of the objects to be accommodated by the overlapping of the transparent parts of the identification unit.

  According to the fourth aspect of the present invention, the entire cup-shaped covering including the flange can function as a colored transparent identification portion, and the entire coloration does not cause visual confusion.

  Hereinafter, the Example of the packaging structure of this invention is described based on FIGS.

  A transparent adhesive layer 3 that exhibits adhesiveness by heating over the entire inner surface of the cup-shaped envelope 2 made of a transparent synthetic resin film with the flange 1 projecting outwardly at the periphery of the opening and the entire surface of the flange 1 connected to the inner surface. The object A in the cup-shaped enclosure 2 is closed and stretched by an opaque (white) sterilization sheet 5 whose periphery is heat sealed to the flange 1 at the opening of the cup-shaped enclosure 2. Keep sealed. The above configuration is the same as the conventional example.

  Therefore, the gist of the present invention is that an identification portion 4 is provided between the transparent synthetic resin film surface constituting the cup-shaped package 2 and the transparent adhesive layer 3 layered on the film surface as shown in FIG.

  The identification unit 4 can perform a series of processes in the process of depositing the adhesive layer 3 on the transparent synthetic resin film surface by a printing technique. That is, as shown in FIG. 3, the identification portion 4 is first formed on one side of the transparent synthetic resin film F running in the unfolded state by the identification layer printer 10, and the adhesive layer printer 11 forms the adhesive layer thereon. 3 is formed so that an identification portion 4 is formed between the adhesive layer 3 shown in FIG. 2 and the film surface constituting the cup-shaped package 2.

  As described above, since the identification unit 4 is formed by a printing press, the identification unit 4 is applied to the entire surface of the cup-shaped covering body 2, partially applied, or transparently colored characters or figures. It is possible to selectively form an identification portion having an arbitrary shape.

  When applied to the entire surface, a transparent colored film is formed. In the case of partial application, an opaque film may be used. In the case of characters and figures, an opaque film is desirable.

  In addition, as for the transparent synthetic resin film which comprises the said cup-shaped enclosure 2, polypropylene (PP), polyethylene (PE), polyester (PET), nylon (NY), polystyrene (PS) etc. are mentioned. The sheet 5 is made of a material having good sterilization properties.

It is a vertical front view of the present invention. It is an enlarged vertical front view of the principal part of FIG. It is explanatory drawing which forms an identification part and an adhesive layer. It is a partial enlarged vertical front view of a conventional product.
