Description

  The present invention relates to a syringe container and a blister package that houses a so-called prefilled syringe that is pre-filled with a chemical solution.

  A so-called prefilled syringe that is pre-filled with a chemical solution is known. This prefilled syringe includes a barrel (injection cylinder), a gasket to be inserted into the barrel, and a plunger (presser) connected to the gasket, and a cap is attached to a mounting nozzle such as an injection needle at the tip of the barrel. It is a syringe that is attached and contains a chemical solution or the like in a space surrounded by a barrel and a gasket, and has been widely used in recent years because it eliminates the work of sucking the chemical solution and does not mix up the drug.

  This prefilled syringe is generally assembled by filling a barrel with a chemical solution, then plugging a gasket, and then assembling a plunger rod into the plugged gasket by screw fitting. Each of the syringes is tray-packed (blister-packed) and distributed for the purpose of alleviating the impact from dropping or the impact from collision with adjacent syringes.

Such blister packs (blister packs) are used for the purpose of preventing the syringe from loosening due to vibration during transportation, coming off of the plunger rod, and damage from impact. Generally, prefilled syringes are fitted in the full length direction. A throttle-shaped storage container that is worn and held is used (for example, Patent Document 1 or Patent Document 2).
Therefore, as the storage container, the opening of the container containing the prefilled syringe is configured as a throttle shape using a plastic sheet or film having a hardness that does not allow the shape to collapse in order to fit and hold the prefilled syringe. The part is sealed with a lid material that is a peelable sealing member, for example, a sealing film.

However, even in this blister package, it cannot be said that it is perfect for a drop impact, and in particular, care is not taken for a drop impact received from the lid surface side. For this reason, when falling from the lid side to the floor surface, the prefilled syringe comes off from the throttle-shaped storage container that is fitted and held, collides with the floor surface, and the syringe cracks or the syringe breaks. There is a possibility.
Furthermore, when the capacity of the syringe increases, the weight of the prefilled syringe itself increases, and even if there is a drop from the bottom side of the blister package (opposite side of the lid material) to the floor surface, cracks due to drop impacts will occur. Occurrence or damage may occur.

  The occurrence of cracks and breakage due to dropping or the like is caused by inflexible materials such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, poly- (4-methylpentene-1), polycarbonate, and cyclic polyolefin. Resin, acrylic resin, acrylonitrile-butadiene-styrene copolymer, polyester such as polyethylene terephthalate, hard resin material such as butadiene-styrene copolymer, polyamide resin, or glass etc. is there.

By the way, in this case, the portion that is likely to be damaged by the impact due to the contact with the floor surface due to the fall of the prefilled syringe packaged in the blister is the tip portion of the syringe body (body portion: barrel), that is, the shoulder portion. The occurrence of cracks and breakage in the shoulder was remarkable.
Therefore, in blister packaging, if a means for protecting the syringe shoulder is provided, the prefilled syringe can be protected from a drop impact, but no active protection means has been taken so far.
JP 2001-104475 A Japanese Patent Laid-Open No. 11-155948

  In view of the above-described situation, the present invention is a blister package for a syringe, particularly a blister package for a prefilled syringe. It is an object to provide a blister package.

  The inventor dropped the prefilled syringe in a non-wrapping state and examined in detail the part that was damaged by the contact impact with the floor surface. That is, it confirmed that it was a shoulder part. Therefore, when the prefilled syringe is blister packed, the portion to be protected from the occurrence of breakage such as cracks is the shoulder portion of the syringe.

  In addition, as a result of various examinations regarding the protection of the shoulder portion of the prefilled syringe, in the storage portion of the blister package that stores the prefilled syringe, the syringe holding protrusion having a flat protrusion surface that can contact the syringe body on the bottom surface If the syringe is provided and held in contact with the syringe, attention is paid to the fact that the projecting portion absorbs the impact as a shock absorber against a drop impact from the fixed bottom portion, and can protect against the occurrence of breakage such as a crack.

In addition, the cause of breakage, cracks, etc. in the syringe shoulder due to the drop impact from the lid surface is due to the fact that the blister-packed syringe comes off the throttle-shaped storage container and the syringe shoulder collides with the floor surface. Therefore, as a protection, the tip of the syringe is fixed to the projecting portion to be held in contact with a fixing agent (adhesive, etc.) to protect the syringe from being removed from the throttle-shaped storage container. We focused on adopting a structure.
As a result, it was confirmed that the syringe could be prevented from being damaged no matter which direction the blister pack dropped on the floor surface, and the present invention was completed.

  Thus, the invention according to claim 1, which is a basic aspect of the present invention, is a blister package in which a lid is sealed on a container body provided with a storage portion formed in a drawn shape so that a syringe is stored. A syringe blister package characterized in that a syringe holding projection having a flat projecting surface capable of contacting the syringe body is provided on the bottom of the container body, and the projection and the syringe are fixed with an adhesive. is there.

  Further, the invention according to claim 2 is the invention according to claim 1, wherein the syringe holding protrusion provided on the bottom surface in the container body is provided in the vicinity of the tip shoulder portion of the syringe. It is a blister package of a syringe.

  Still further, the invention described in claim 3 is the invention described in claims 1 and 2, wherein the syringe holding protrusion provided on the bottom surface in the container body is fitted to the tip shoulder of the syringe. It is a blister package of a syringe which is configured as a throttle shape to be accommodated.

The present invention configured as described above is to protect the tip of the syringe from a drop impact caused by a drop accident of a blister package for packaging the syringe. A package that does not cause breakage is provided. Therefore, the productivity of the syringe is improved, and the syringe that has been cracked is not used at the medical site, so that the occurrence of a medical error or the like can be prevented.
Moreover, since it is possible to avoid breakage and cracking of the syringe by using the blister package provided by the present invention, the selection range of the syringe material is expanded, and the syringe wall thickness can be set to an appropriate range. There is an advantage that a syringe having a simple shape can be produced.

Details of the present invention will be described below with reference to the drawings.
In the following description, a prefilled syringe is described as an example of a syringe, but the same applies to a syringe not filled with a chemical solution.

  FIG. 1 is a schematic plan view showing a state in which a sealing film as a lid material is peeled off from a blister package containing a prefilled syringe according to an embodiment of the present invention.

  That is, the blister package 1 containing the prefilled syringe provided by the present invention is a lid material on the container main body 21 provided with the storage portion 10 formed in a drawn shape so that the prefilled syringe 3 is stored, for example, sealing A film (not shown) is sealed, and the syringe housing portion 10 of the blister package 1 has a flat projecting surface that comes into contact with and holds the distal end portion 31 of the prefilled syringe and can contact the syringe body. The protrusion 11 provided is formed, and the syringe tip 31 is held in contact with the protrusion 11. In addition, 22 is a seal | sticker part which seals the sealing film 101 (not shown) which is a cover material with respect to a blister package.

In the present embodiment, the syringe housing 10 is formed with a throttle-shaped protrusion 12 on which the main body barrel 32 of the prefilled syringe 3 is not fitted and held. The part 32 is fitted and stored. Therefore, in the present embodiment, the prefilled syringe is fitted and housed by the one narrowed protrusion 12 provided in the housing 10.
The position where the throttle-shaped protrusion 12 is provided may be an arbitrary portion of the syringe body, and the number is not necessarily one.

  The prefilled syringe 3 includes a barrel (injection cylinder) 4, a gasket (not shown) inserted into the barrel, and a plunger (presser) 5 connected to the gasket, and an injection needle at the tip of the barrel. A cap 7 is attached to the mounting nozzle 6 such as, and a chemical solution 100 (not shown) or the like is filled in the barrel.

  The portion of the syringe 3 where the blister pack 1 containing the prefilled syringe is impacted by contact with the floor surface due to dropping or the like and the syringe is damaged or cracked is the shoulder portion 33 of the syringe 3. Therefore, in the blister package 1 of the present invention, in the storage unit 10 for storing the syringe, a flat protruding surface that can contact the syringe body is provided on the bottom surface of the storage unit 10 in order to protect the shoulder portion 33 from the impact of a drop accident. A syringe holding projection 11 is provided, and the projection 11 is used as a cushioning material to protect against impact from the bottom of the package.

  That is, for example, even if the blister package 1 is dropped due to the contact and holding of the syringe tip 31 to the protrusion 11, the syringe tip 11 is directly placed on the floor surface by the convex portion of the throttle-shaped protrusion 11. As a result, the syringe shoulder 33, which is prone to cracking and breakage, is protected.

In addition, in the blister package 1 based on this embodiment of the present invention, the syringe tip 31 is fixed by the adhesive 81 in the protruding portion 11.
The state is shown in FIG. 2, and an enlarged cross-sectional view taken along line BB in FIG. 1 is shown.

For example, a sealing film (not shown) is sealed, and the syringe holding protrusion includes a flat protrusion on the bottom surface of the syringe housing 10 of the blister package 1 that can contact the syringe body. However, the protruding portion is formed as a throttle-shaped protruding portion 11 for fitting and storing the tip portion 31 of the prefilled syringe, and the syringe tip portion 31 is fitted and stored in the throttle-shaped protruding portion 11. In addition, 22 is a seal | sticker part which seals the sealing film 101 (not shown) which is a cover material with respect to a blister package.

  Further, in the present embodiment, the syringe storage portion 10 is formed with a throttle-shaped protrusion 12 on which the proximal end body portion 32 of the prefilled syringe 3 is not fitted and stored, and the syringe-shaped protrusion 12 is provided with a syringe. The base end barrel portion 32 is fitted and stored. Therefore, in this embodiment, the prefilled syringe is fitted and housed by the two drawing-shaped protrusions 11 and 12 provided in the housing part 10.

  In this case, a portion where the blister package 1 containing the prefilled syringe is impacted by contact with the floor surface due to dropping or the like, and the syringe is damaged or cracked is the shoulder portion 33 of the syringe 3. Therefore, in the blister package 1 of the present embodiment, the distal end portion 31 of the syringe is fitted in the throttle shape of the accommodating portion 10 in order to protect the shoulder portion 33 from the impact of a drop accident in the accommodating portion 10 that accommodates the syringe. It is desirable to form the throttle-shaped protrusion 11 to be received and stored, and to fit and store the syringe tip 31 into the throttle-shaped protrusion 11.

  For example, even if the blister package 1 is dropped due to the fitting and storing of the syringe tip 31 in the throttle-shaped protrusion 11, the syringe tip 11 is directly placed on the floor by the convex portion of the throttle-shaped protrusion 11. Contact with the surface is avoided, and as a result, the syringe shoulder 33, which is prone to cracking and breakage, is protected.

In addition, in the blister package 1 according to the present embodiment of the present invention, the syringe tip 31 is fixed by the adhesive 81 in the drawing-shaped protrusion 11.
