Description

  The present invention provides a container main body including a container main body including a container capable of storing contents, and a container including a cap that is attached to the container main body and seals an opening of the container main body. The present invention relates to a packaging film that is tightly attached to a cap and packaged.

2. Description of the Related Art Conventionally, a drug container that stores a liquid such as an infusion drug such as an infusion is sealed with a lid member (rubber plug or the like) made of rubber or the like, and the opening and lid member of the container are made of resin. Covered with a cap made of metal or metal.
When using the medicine container, a part of the cap is broken or separated to expose a part of the sealing lid member. Then, without opening the rubber stopper, the injection needle is pierced into the sealed lid member at the exposed portion and used for infusion.

A plurality of (for example, two types) drugs may be stored in the drug container, and two types of drugs are stored in separate storage units before use, and the two types of drugs are stored during use. There is known a configuration in which the contained portions are aseptically communicated to mix these drugs and used for infusion.
As such a medicine container, there exists a thing which cancels the sealing state of the communicating part which connects each accommodating part by rotation operation (for example, patent documents 1). That is, in use, since the communicating portion is opened by rotating the protruding piece that seals the communicating portion by rotating the cap member, a plurality of medicines can be mixed by a simple operation.

Moreover, in such a medicine container, etc., in order to prevent the container from being soiled at the distribution stage and the opening of the lid due to an error, the container is generally packaged with a packaging film such as a shrink film ( For example, Patent Document 2).
Patent Document 2 describes a two-component mixing container packaged with a shrink film. In this container, a first container body containing a first agent and a second container body containing a second agent are connected via a breakable bottom wall. Then, after cutting and removing the shrink film, when the cap of the container is screwed down to break the bottom wall, the upper second agent falls into the first agent and the two agents can be mixed.
In this document, it is desirable to coat and wrap the entire container with a shrink film because there is a risk that the bottom wall may be broken by screwing down the cap by mistake.

Japanese Patent No. 3281388 (refer to pages 12 to 13 and FIG. 31) Japanese Patent No. 3298747 (see paragraphs 0008, 0017, FIG. 1, etc.)

  In the medicine container disclosed in Patent Document 1, infusion is used by inserting an injection needle into the sealing lid member before opening the communicating portion by rotating the cap member, that is, before mixing a plurality of medicines. There is a risk of serving. In this case, if the container contains two unmixed drugs in isolation, only one drug is administered to the patient, and the drug is administered to the patient in a state where the desired mixed drug cannot be obtained. It will be.

  Moreover, in the two-component mixing container packaged with the packaging film described in Patent Document 2, after the shrink film is cut and removed, the cap of the container is screwed down to mix the two agents. However, in this case as well, there is a possibility that the drug is administered to the patient without performing the mixing operation of the drug after the shrink film is removed.

  Therefore, it is desirable to provide a patient with a desired mixed medicine after reliably performing an operation of mixing a plurality of medicines when opening the container. That is, it is desired that the medicine cannot be provided in a state where the operation of mixing a plurality of medicines is not performed.

  Moreover, in the shrink film which packages a storage container, there exists a possibility that the said film may be fractured | ruptured from the location other than the part which is planning a fracture | rupture, and the said film may be removed from a storage container. And when the said film cannot be fracture | ruptured favorably, the problem of taking time to remove the said film from a storage container arises.

  Accordingly, an object of the present invention is to provide a packaging film that can be removed after the cap is rotated when the container is opened.

  In order to achieve the above object, the first characteristic configuration of the packaging film according to the present invention includes a container main body provided with a container capable of accommodating contents, and an opening of the container main body attached to the container main body. A packaging film that is tightly packed with the container body and the cap of the storage container having a cap to be stopped, and when formed into a cylindrical shape, promotes the first break along the outer circumferential direction of the cylindrical film A portion of the first breakage accelerating portion is displaced in the direction of the container body along the cylindrical axis to form a second rupture accelerating portion, and the first rupture accelerating portion and the second From the periphery of the boundary position with the breakage promoting portion, a cutout promoting portion is provided in the direction of the cap along the cylindrical axis.

  According to said 1st characteristic structure, the 1st fracture | rupture acceleration | stimulation part broken by the rotation operation of the cap with which the container main body was mounted | worn by screwing etc. can be provided so that the outer peripheral direction of a container main body may be covered. . And a packaging film is isolate | separated into a cap side member and an accommodating part side member, when a 1st fracture | rupture promotion part is fractured | ruptured by rotation operation of a cap. At this time, the second breakage accelerating part is formed in a state in which a part of the first breakage accelerating part is displaced in the direction of the container body along the cylindrical axis, so that a portion protruding from the cap side member is formed. Is done. This protruding part can be used as a knob piece when the packaging film is removed from the container.

  Furthermore, since the cutout promoting portion is formed in the direction of the cap along the cylindrical axis from the boundary position between the first breakage promoting portion and the second breakage promoting portion or its periphery, the protruding portion (knob piece) ) Is pulled to break this cut-off promoting portion, a part of the packaging film (cap side member) can be easily removed from the storage container.

Therefore, in the case of the packaging film described in the first characteristic configuration of the present invention, the projecting portion (knob piece) that becomes a trigger for removing the packaging film is not formed before the rotation operation of the cap. In order to remove the film, the consciousness that the cap needs to be rotated first works. And the protrusion part (knob piece) is formed by rotation operation of this cap. Then, the user is aware that it is necessary to pull the protruding portion. Then, by pulling the protruding portion, a series of operations of breaking the cut promoting portion and peeling off the cap-side member that is a part of the packaging film can be reliably performed.
That is, since the protruding portion (knob piece) that appears by rotating the cap guides the operation procedure for peeling the packaging film, the reliability of the series of opening operations described above when opening the container is improved.

  In order to achieve the above object, the second characteristic configuration of the packaging film according to the present invention includes: a container main body provided with an accommodating portion capable of individually accommodating a plurality of medicines; and the container main body that can be attached to the container main body A cap that can be covered on the outside of the sealing lid member that seals the opening of the cap, and a plurality of drugs can be mixed by rotating the cap relative to the container main body. A packaging film that is packaged in close contact with the container body and the cap. When the packaging film is formed in a cylindrical shape, a first breakage promoting portion is provided along the outer peripheral direction of the tubular film, and the first breakage promoting portion is provided. A part of is displaced in the direction of the container body along the cylindrical axis to form a second breakage promoting portion, and further, from the periphery of the boundary position between the first breakage promoting portion and the second breakage promoting portion, Along the cylinder axis In the direction of cap to a point having a cut promoting portion.

  According to said 2nd characteristic structure, the 1st fracture | rupture promotion part fractured | ruptured by the rotation operation of a cap can be provided so that the outer peripheral direction of a container main body may be covered. And a packaging film is isolate | separated into a cap side member and an accommodating part side member, when a 1st fracture | rupture promotion part is fractured | ruptured by rotation operation of a cap. At this time, the second breakage accelerating part is formed in a state in which a part of the first breakage accelerating part is displaced in the direction of the container body along the cylindrical axis, so that a portion protruding from the cap side member is formed. Is done. This protruding part can be used as a knob piece when the packaging film is removed from the container.

Furthermore, since the cutout promoting portion is formed in the direction of the cap along the cylindrical axis from the boundary position between the first breakage promoting portion and the second breakage promoting portion or its periphery, the protruding portion (knob piece) ) Is broken to break this cut-off promoting portion, a part of the packaging film (cap side member) can be easily removed from the medicine container.
Then, by pulling the protruding portion, the cut promoting portion is broken and the cap side member that is a part of the packaging film is peeled off, thereby removing the cap or the cap side member and removing the sealing lid member. Exposure is possible.

  And, since the liquid transfer means such as an injection needle can penetrate only after the sealing lid member is exposed, the mixed medicine obtained by the relative rotation of the cap with respect to the container body can be administered to the patient.

  Therefore, if it is a packaging film as described in the 2nd characteristic structure of this invention, the protrusion part (knob piece) for guide | inducing the operation procedure which peels a packaging film simultaneously with mixing several chemical | medical agents by operation which rotates a cap Appears and the packaging film can be easily removed from the medicine container. Then, when the packaging film is completely peeled off, the mixing of the medicine is surely finished, and the desired mixed medicine can be administered to the patient. Thereby, since it can prevent effectively administering a medicine to a patient in an unmixed state, the safety at the time of use of a medicine storage container improves more.

  The 3rd characteristic structure of the packaging film which concerns on this invention exists in the point which said 2nd fracture | rupture promotion part has a side part in alignment with a cylinder axial center direction from the said boundary position periphery.

The side portion along the cylinder axis direction is a side substantially perpendicular to the rotation direction of the cap. And the 2nd breakage promotion part other than the said side part can be comprised so that it may become substantially parallel to the 1st breakage promotion part.
Therefore, according to the third characteristic configuration, the protruding portion (knob piece) formed by the breakage of the breakage promoting portion by the rotation operation of the cap can be configured to have a protruding rectangular shape, for example.
The rectangular part (knob piece) formed in this way is formed by breaking the side part substantially perpendicular to the breakage promoting part and the second breakage promoting part substantially parallel to the breakage promoting part. Therefore, as a result of the side portion being able to smoothly break in the same direction as the rotation of the cap by the pulling force accompanying the rotation of the cap, the protruding portion (knob piece) can be rationally formed. it can.

  The 4th characteristic structure of the packaging film which concerns on this invention exists in the point which formed the notch over the full length previously in the said side part.

  According to the fourth feature configuration, since it is not necessary to break the side portion when the cap rotates, the protruding portion (knob piece) can be formed more rationally.

  The 5th characteristic structure of the packaging film which concerns on this invention exists in the point which made the film | membrane edge part area | region in the expansion | extension direction of the said cutting promotion part the area | region in which the said cutting promotion part is not formed.

If the cut promoting part is formed up to the film end, the user may accidentally break the cut promoting part from the film end side before removing the cap and remove the packaging film from the container. In this case, it may be provided to the patient in a state where the mixed medicine cannot be obtained.
For this reason, as in the fifth characteristic configuration, by removing the cut promoting portion from the film end region, it is possible to effectively prevent the packaging film from being removed from the container before the cap is rotated.

  The 6th characteristic structure of the packaging film which concerns on this invention exists in the point which provided the adhesion part in the both sides of the said 1st fracture | rupture promotion part inside the said cylindrical film.

According to the sixth characteristic configuration, the cap-side member and the accommodating portion-side member formed by breaking the packaging film can be provided with an adhesive portion that is fixed to the accommodating container on the surface on the accommodating container side.
Then, by providing the adhesive portion on both the cap side member and the accommodating portion side member, when the container body and the cap are relatively rotated, the cap and the cap side member cooperate with each other, and the container body The accommodating part side member can be made to cooperate. Therefore, when the cap and the container main body are rotated relative to each other, the cap side member and the accommodating portion side member are reliably moved relative to each other, so that the breakage promoting portion can be reliably broken.

Embodiments of the present invention will be described below with reference to the drawings.
The packaging film Y of this invention is shown in FIG. 1, and the schematic at the time of applying this packaging film Y to the chemical | medical agent storage container X is shown in FIGS.
The medicine container X is mainly used for medical purposes. For example, the medicine container X is a container for supplying medicine such as medical infusion to a patient as a liquid. The medicine container X in this embodiment accommodates a plurality of medicines in separate storage members when not in use, and aseptically communicates a container containing a plurality of medicines when used to mix these medicines However, it is configured to be capable of being used for infusion. The plurality of drugs may be all liquid drugs, or a combination of liquid and solid drugs (including powders).

In addition, the container applicable to the packaging film Y of the present invention is not limited to a medical drug container, and for example, the first agent and the second agent are mixed immediately before use. Any container that contains a plurality of medicines / solids that react with each other over time to reduce the efficacy is applicable. Specifically, a container or the like that stores a preparation-type medicine at the time of use can be applied.
Furthermore, although not illustrated, the packaging film Y of the present invention can be applied not only to a container in which two agents are mixed as described above, but also to a container that stores food and beverages as contents. At this time, the opening of the storage container is sealed with a cap attached to the storage container by screwing or the like.

(Drug container)
The medicine container X has a container body 1 and a cap 40 (see FIGS. 2 to 4).
The container main body 1 can separately store a plurality of (for example, two types) liquid medicines, and is configured so that these liquid medicines can be mixed aseptically during use.
For example, there is a form in which two types of liquid medicine can be mixed by a rotating operation. As a mixing mechanism for mixing medicines, a known method for communicating two chambers may be used.
Specifically, the form in which the sealing member of the communication path is opened and moved relative to the communication hole by the rotation operation, the form in which the sealing member of the communication path is separated by the rotation operation and the two chambers communicate with each other, There are forms that change from a closed state to a connected state.
In the present embodiment, a mixing mechanism in which the sealing member of the communication passage is opened and moved with respect to the communication hole by a rotation operation is illustrated.

That is, the storage container main body 1 includes the first storage member 10 that stores the first drug and the second storage member 20 that stores the second drug and communicates with the first storage member 10 via the communication path 60. It is provided. As the medicine storage portion, the first storage member 10 forms a medicine storage space 13 for storing the first medicine, and the second storage member 20 forms a medicine storage space 21 for storing the second medicine, respectively. It is possible to form in the capacity | capacitance according to the quantity of the chemical | medical agent to do. For example, the medicine storage space 13 is configured to have a capacity of 20 mL, and the medicine storage space 21 is configured to have a capacity of 480 mL.
Although the 1st accommodating member 10 and the 2nd accommodating member 20 can be shape | molded in arbitrary shapes, since the 1st accommodating member 10 needs to rotate the sealing lid member 30 and the cap 40, it is cylindrical. It is preferable to form the film.
A mounting engagement portion 11 to which the cap 40 can be engaged and mounted is provided on the outer surface of the first housing member 10. And the cap main body engaging part 43 and the mounting | wearing engaging part 11 of the cap 40 engage, and the cap 40 and the container main body 1 can be rotated relatively.

The communication path 60 can be sealed or opened by the sealing member 50. That is, the sealing member 50 has a sealing posture in which the communication passage 60 is sealed (see FIG. 5A) and an opening posture in a state in which the sealing of the communication passage 60 is released (see FIG. 5B). ) Can be switched freely. The sealing member 50 is engaged and fixed to the sealing lid member 30.
When the sealing member 50 is in the sealing posture, the two kinds of medicines can be stored in separate storage spaces (the medicine storage space 13 and the medicine storage space 21), and the sealing member 50 is in the opening posture. In some cases, it is possible to mix two kinds of medicines by aseptically communicating a storage space containing two kinds of medicines.

  The opening 12 provided in the first housing member 10 is hermetically sealed by a sealing lid member 30 made of an elastic material such as a rubber material, and the sealing lid member 30 can be rotated around an axis. The cap 40 is engaged with and attached to the first housing member 10 (the housing body 1).

  The cap 40 is attachable to the container main body 1 and is formed so as to be covered outside the sealing lid member 30 that seals the opening 12 of the container main body 1. “Coverable” means that the sealing lid member 30 is provided. At this time, the cap 40 preferably covers the sealing lid member 30 aseptically.

  When using the medicine container X, the cap 40 is rotated relative to the container body 1. At this time, the sealing lid member 30 and the sealing member 50 are rotated in conjunction with the cap 40, the sealing member 50 is in the opening posture, and two kinds of drugs can be mixed aseptically. After the medicine is mixed in this way, an injection needle (liquid transfer means) is inserted into the sealing lid member 30 so as to be used for infusion without opening the sealing lid member 30.

  Thus, it is important that the liquid transfer means is inserted only after the cap 40 is opened and removed. That is, the cap 40 is configured such that it can be removed after aseptic mixing of a plurality of drugs. If the cap 40 can be removed before the mixing, it is inconvenient because the liquid transfer means can penetrate the sealing lid member 30 before mixing the medicine and can be used for infusion.

  In this embodiment, the cap 40 is configured to have a cap body 41 and a detaching member 42, and after removing the cap side member Y 1 of the packaging film Y, only the detaching member 42 that is a part of the cap 40 is removed. In this case, all or part of the surface of the sealing lid member 30 is exposed.

(Wrapping film)
The packaging film Y of the present invention is a film that is in close contact with the container body 1 and the cap 40 of the medicine container X described above for packaging. For example, the packaging film Y can be packaged in close contact with the boundary between at least a part of the container main body 1 and the cap 40 of the drug container X, but is in close contact with the entire drug container X. It may be packaged.
As shown in FIGS. 1 to 3, when the film Y to be packaged is formed in a cylindrical shape, the first breakage promoting portion 100 is provided along the outer peripheral direction of the tubular film Y, and the first breakage promoting portion 100 is provided. Is displaced in the direction of the container main body 1 along the cylinder axis Z to form the second breakage accelerating portion 101, and the boundary position 103 between the first rupture accelerating portion 100 and the second rupture accelerating portion 101. From the periphery, a cut-out promoting portion 110 is provided in the direction of the cap 40 along the cylinder axis Z.
The film Y to be packaged is formed in a cylindrical shape, but may have a cylindrical shape with a crease. In other words, it may be substantially cylindrical.

With the configuration of the packaging film Y, the first breakage promoting portion 100 that is broken by the rotation operation of the cap 40 can be provided so as to extend in the outer peripheral direction of the container main body 1. The first breakage accelerating portion 100 can be provided on substantially the entire outer periphery, or on a part of the outer periphery. In this embodiment, the case where it provides over the perimeter of an outer periphery is illustrated.
The packaging film Y is separated into the cap side member Y1 and the medicine container side member Y2 when the first breakage promoting portion 100 is broken by the rotation operation of the cap 40. At this time, the second breakage accelerating portion 101 is formed in a state in which a part of the first breakage accelerating portion 100 is displaced in the direction of the container main body 1 along the cylinder axis Z, so that the cap side member Y1 It is possible to configure so that the knob piece 120 can be formed (see FIG. 6).

  Furthermore, since the cut promoting part 110 is formed in the direction of the cap 40 along the cylindrical axis Z from the periphery of the boundary position 103 between the first fracture promoting part 100 and the second fracture promoting part 101, the knob piece 120. It can form as a site | part broken by pulling operation. Then, the cut promoting part 110 can be broken so that the cap side member Y1 can be removed from the medicine container X.

  The packaging film Y is preferably exemplified by a shrink film that is a heat-shrinkable film. Hereinafter, the case where the shrink film is applied to the packaging film of the present invention will be described in detail.

Shrink film As the shrink film Y, a transparent or translucent film is preferably exemplified in order to improve the visibility of the container. As the material, for example, uniaxially or biaxially stretched polyvinyl chloride, polyethylene terephthalate (PET), polystyrene, polypropylene, or the like can be used.
PET is most preferably used because there are few harmful substances generated when the shrink film Y is removed from the container and disposed after being discarded.

In addition, when the shrink film Y has, for example, a cylindrical form having an overlapped portion in which both end portions of one sheet-like shrink film are overlapped and joined, the shrink film Y is thermally contracted in the circumferential direction of the shrink film Y, Those that adhere closely to the surface can be applied.
Thermal shrinkage refers to shrinking the shrink film Y by, for example, treatment with hot air, immersion in hot water, steam spraying, or the like.
That is, the shrink film Y made into a cylindrical shape is attached to the outer peripheral surface of a medicine container X such as a glass bottle or a plastic bottle, and is used by being thermally contracted and closely attached to the container. At this time, the entire container may be packaged, or may be packaged so as to cover only the vicinity of the boundary between part of the container main body 1 and the cap 40. When packaging the whole container, shrink film Y is made into a bottomed form, and it is attached to the outer peripheral surface of the container and thermally contracted.

  The shrink film Y can wrap the container in a single layer or multiple layers. Furthermore, the shrink film Y can be set in various dimensions depending on the size of the container to be packaged. For example, in the case of a container for supplying a medicine such as a medical infusion to a patient or the like, it is about 65 mm wide and about 150 mm long in the state of a sheet-like film. At this time, the thickness is usually about 40 to 60 μm. Those are preferably used.

  On the shrink film Y, necessary characters and designs can be printed in advance. Although the printing location is not limited, for example, the printing area 150 can be provided. The printing area 150 can be provided with a base processing for making it easier to print characters / designs. Further, it is possible to apply an overcoat varnish or the like for preventing scratches on the upper surface of printed characters / designs.

  The shrink film Y is configured such that it can be easily separated from the container so that the contents can be provided quickly in use. As a method of satisfying this requirement, generally, a perforation process and a thin-wall process are performed on a planned fracture site.

Breaking promotion part The 1st breaking promotion part 100 and the 2nd breaking promotion part 101 are the planned fracture parts fractured by rotation operation of cap 40, and are provided along the perimeter direction of storage container main part 1 (Drawing 1-Drawing 1). 3). The breakage promoting portion 100 is configured by forming a perforation line, a thin-walled portion, or the like at a planned breakage portion of the shrink film Y. The perforation line means a line in which a plurality of cut lines are arranged intermittently. In this embodiment, the breakage promoting portion 100 is formed from one open end side to the other open end side of the sheet-like shrink film (FIG. 1A). Thus, when the shrink film is brought into close contact with the container in a tubular form (FIG. 1C), the first breakage promoting portion 100 and the second breakage promoting portion 101 are configured to make one round in the circumferential direction.

  At this time, it is desirable that the first breakage promoting portion 100 is configured not to be disposed at the same position as the lower end portion of the cap 40 (see FIG. 3). For example, if it arrange | positions so that it may be located under the lower end part (for example, 5-15 mm) of the cap 40, it can prevent that the fracture | rupture acceleration | stimulation part 100 is fractured | ruptured accidentally by the contact of the edge part of the cap 40 and another thing.

  The perforation line or the like, which is the fracture promoting portion, can be formed in a straight line shape or a curved line shape, and is appropriately selected depending on the application.

  When the first breakage promoting portion 100 and the second breakage promoting portion 101 are thus provided, the shrink film Y that is in close contact with the container along the perforation line can be easily torn. In the present invention, when the container main body 1 and the cap 40 are rotated relative to each other by the rotation of the cap 40, the first breakage promoting portion 100 and the second breakage promoting portion 101 are broken. At this time, the shrink film Y is separated into the cap side member Y1 and the medicine container side member Y2. And since the 2nd fracture | rupture promotion part 101 is formed so that a part of 1st fracture | rupture promotion part 100 may be displaced in the direction of the container main body 1 along the cylinder axial center Z, it is in cap side member Y1. The knob piece 120 can be formed. The knob piece 120 will be described below.

The knob piece 120 serves as a trigger for removing the shrink film Y from the container, but the knob piece 120 of the present invention is not formed from the beginning. That is, the knob piece 120 is formed for the first time by the rotation of the cap 40. Therefore, unless the cap 40 is rotated, the shrink film Y is difficult to remove from the container.

  As described above, when the second breakage promoting portion 101 is formed in a straight line shape, the knob piece 120 can be formed in a rectangular shape, a triangular shape, or the like. Moreover, when the said fracture | rupture promotion part 101 is formed in curve shape, the knob piece 120 can be made into semicircle shape etc. Therefore, in consideration of the size and shape of the medicine container X, various shapes suitable for the user to grip the knob piece 120 can be applied.

The second breakage accelerating portion 101 can be configured to have a side portion 104 along the cylindrical axis Z direction from the periphery of the boundary position 103. The side portion 104 along the cylinder axis direction is a side substantially perpendicular to the rotation direction of the cap 40. The second breakage promoting portion 101 (breaking portion 101a) other than the side portion 104 can be configured to be substantially parallel to the first breakage promoting portion 100.
Thereby, the knob piece 120 can be configured to have a protruding rectangular shape when the first breakage promoting portion 100 and the second breakage promoting portion 101 are broken by the rotation operation of the cap 40 (FIG. 1). (See FIG. 6).
At this time, the knob piece 120 is formed by breaking a side portion 104 substantially perpendicular to the breakage promoting portion 100 and a breakage portion 101a (part of the second breakage promoting portion 101) substantially parallel to the breakage promoting portion 100. The Therefore, the side portion 104 can be smoothly broken in substantially the same direction as the rotation of the cap 40 by the pulling force accompanying the rotation of the cap 40. As a result, the knob piece 120 can be reasonably formed.

  Moreover, the side part 104 can be comprised so that a notch may be previously formed over the full length (refer FIG.1 (b)). If comprised in this way, it is not necessary to fracture | rupture the side part 104 at the time of rotation of the cap 40, Only the fracture | rupture part 101a substantially parallel to the fracture | rupture promotion part 100 can be fractured | ruptured, and the knob piece 120 can be formed more rationally. it can.

Cut Promotion Part The cut promotion part 110 is a part to be fractured that is broken by pulling the knob piece 120. Therefore, the cut promoting part 110 is formed toward the film end part 140 of the cap side member Y1 in a state where the side part 104 extending along the cylinder axis direction of the knob piece 120 is extended (see FIG. 1 and the like). The cut promoting part 110 is configured by forming a perforation line, a thin part, and the like at a planned breaking part, similar to the first break promoting part 100 and the second break promoting part 101 described above.
And the cutting promotion part 110 can be fractured | ruptured and the cap side member Y1 can be reliably removed from the chemical | medical agent storage container X. FIG.

  Here, the cut promoting part 110 may not be formed up to the open end 140 of the cap side member Y1. That is, the film end region 141 in the extending direction of the cut promoting portion 110 can be a region where the cut promoting portion 110 is not formed (see FIG. 1).

If the cut promoting part 110 is formed up to the film end 140, the user may accidentally break the cut promoting part 110 from the film end 140 side before removing the cap 40 and remove the shrink film Y from the container. . In this case, it may be provided to the patient in a state where the mixed medicine cannot be obtained. Therefore, the cut promotion part 110 can prevent removing the shrink film Y from the container before the rotation of the cap 40 as a state where the film end region 141 is not formed.
When the cap-side member Y1 is removed from the medicine container X, the medicine container-side member Y2 that is another shrink film piece may remain in close contact with the container body 1.

Adhesive part It is possible to provide an adhesive part on both sides of the first fracture promoting part inside the tubular film. Thereby, the adhesion part 130 to which the shrink film Y adheres to the medicine container 1 can be provided on the surface on the medicine container 1 side in the cap side member Y1 and the medicine container side member Y2 (see FIG. 1). ).

An adhesive that adheres the shrink film Y and the outer periphery of the medicine container X is applied to the adhesive portion 130. The adhesive can be applied as long as it is a type of adhesive that exhibits adhesiveness by heat treatment, such as a heat-sensitive adhesive.
The adhesive part 130 is provided, for example, so as to face both the cap side member Y1 (130a-b) and the medicine container side member Y2 (130c-d) of the shrink film Y. By providing the bonding part 130 on both the cap side member Y1 and the medicine container side member Y2, the cap 40 and the cap side member Y1 cooperate when the container main body 1 and the cap 40 are relatively rotated. And the container main body 1 and the medicine container side member Y2 can be made to cooperate. Therefore, when the cap 40 and the container main body 1 are relatively rotated, the cap-side member Y1 and the medicine container-side member Y2 reliably move relative to each other, so that the breakage promoting portions 100 and 101 can be reliably broken. it can.
Assuming that the adhesive portion 130 is not provided on the cap-side member Y1, when the container main body 1 and the cap 40 are relatively rotated, the cap 40 and the cap-side member Y1 do not cooperate, and the breakage promoting portion. It becomes difficult to break 100. And since the knob piece 120 is not formed when the fracture | rupture promotion part 100 is not fractured, it becomes difficult to remove the shrink film Y.

  In the present embodiment, an example in which the four adhesion portions 130a to 130d are formed is illustrated, but the present invention is not limited to four locations. In addition, the area of each bonding portion can be set as appropriate, but the setting of the area is adjusted by the shape and material of the cap 40 and the container main body 1.

  As described above, in the shrink film Y of the present invention, the knob piece 120 for guiding the operation procedure for peeling the shrink film Y appears at the same time when a plurality of medicines are mixed by the operation of rotating the cap 40, and the shrink film 120 appears. The film Y can be easily removed from the medicine container X.

Since the medicine container X is packaged with the shrink film Y, the user can be made aware that it is necessary to perform an operation for peeling the shrink film Y in use.
Further, since the knob piece 120 that is a trigger for removing the shrink film Y is not formed before the rotation operation of the cap 40, in order to remove the shrink film Y, it is necessary to first rotate the cap. That consciousness works.
The operation of rotating the cap 40 to break the first breakage promoting portion 100 and the second breakage promoting portion 101 of the shrink film Y also serves as a mixing operation of the medicine. The knob piece 120 is formed by the rotation operation of the cap 40. Then, the user is aware that it is necessary to pull the knob piece.
Then, by pulling the knob piece 120, the cap 40 or the cap can be removed by reliably performing a series of operations of breaking the cut-off promoting portion 110 and peeling off the cap-side member Y1 that is a part of the shrink film Y. The sealing member 30 can be exposed by detaching the detaching member 42 that is a part of the sealing member 42.

  And since liquid transfer means, such as an injection needle, can penetrate only after the sealing lid member 30 is exposed, the mixed medicine obtained by relative rotation of the cap 40 with respect to the container main body 1 can be administered to the patient.

  In this way, by guiding the operation procedure for peeling the shrink film Y, the medicine is properly mixed. Therefore, when the shrink film Y has been peeled off, the mixing of the medicine is surely completed, and the desired mixed medicine is supplied to the patient. Can be administered. Thereby, since it can prevent effectively administering a medicine to a patient in an unmixed state, the safety at the time of use of medicine storage container X improves more.

  Preferably, after the first drug and the second drug are sufficiently mixed, the drug container X is turned over so that the first container 10 faces down with the injection needle inserted into the sealing lid member 30. Then, the mixed drug of the first drug and the second drug is supplied to the patient through the injection needle.

(Shrink film manufacturing process)
Below, the manufacturing process of the shrink film Y of this invention is demonstrated.
The shrink film Y of the present invention is applied to a container in the form of a sheet (FIG. 1 (a)) in a cylindrical shape (FIG. 1 (c)) as described below. After forming the perforation lines of the first breakage promoting portion 100, the second breakage promoting portion 101, and the cutout promoting portion 110, the tubular shape is formed. However, the present invention is not limited to this, and the perforated line may be formed after the sheet-like film is bent at the bending position L as shown below.

First, a method for producing a tubular shrink film Y will be described.
The tubular shrink film Y can be formed by, for example, heat-welding both ends in the width direction of the sheet-like film.
In the case of heat-welding, for example, both ends in the width direction of the sheet-like film are overlapped, and this polymerized portion is heated, so that the films in the polymerized portion are welded together.

Next, a process of forming a perforation line that is the first breakage promoting part 100, the second breakage promoting part 101, and the cut promoting part 110 will be described.
The sheet-like film is bent at the bending position L to be in a state where two sheets are stacked (FIG. 1B). At this time, the sheet-like film is bent at a position where the breakage promoting portion 100 and the cutout promoting portion 110 are symmetrical at the bending position L. In this state, the perforated line forming blade is pressed against the folded shrink film Y. Thereby, a perforation line is formed in the shrink film Y which became two sheets. In this way, the first breakage promoting part 100, the second breakage promoting part 101, and the cut promoting part 110 are formed.

  Various dimensions can be set as the dimension of the perforation line. For example, the length of the cut line is formed to about 0.5 to 1.2 mm, and the interval between these is formed to about 0.5 to 1.2 mm.

(Container packaging process)
Below, the process of closely packaging the medicine container X with the shrink film Y will be described.
The periphery of the packaged body such as the medicine container X is covered with the cylindrical shrink film Y obtained as described above. In this state, heat treatment is performed by hot air treatment, immersion in hot water, or steam spray treatment. Thereby, the shrink film Y is heat-shrinked and adheres to the periphery of the medicine container X. At this time, since the adhesive 130 is coated with a type of adhesive that exhibits adhesiveness by heat treatment, the shrink film Y and the outer periphery of the medicine container X can be fixed.
Further, in this embodiment, the upper open end side of the shrink film Y is bent on the upper surface side of the cap 40 and the medicine container X is packaged so as to adhere closely along the circumferential end of the cap 40. Not only the packaging form but also the entire medicine container X may be packaged.

  The packaging film of the present invention can be used for packaging a medicine container for medical use, that is, a medicine container configured so that a plurality of medicines can be mixed by relative rotation of the cap with respect to the container body. In addition, the container is not limited to a medical drug storage container, and the first agent and the second agent are mixed and used immediately before use. Any container that accommodates the drug / solid matter can be applied. Furthermore, the present invention can be applied not only to a container in a form in which two agents are mixed, but also to a storage container that stores food and beverages as contents.
