DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS.

The mounting plate 1 is made of a plastic having flexibility and elasticity. As shown in FIGS. 1 and 3, side plates 11 are vertically provided at both ends in the width direction of the upper plate 10, respectively. 11 are provided at the lower end of the mutually facing surfaces.
Are formed in the horizontal direction, and the tips of the ridges 12 are rounded and chamfered. Further, the mounting plate 1 has a plurality of inverted truncated cones 13 erected along the center line between the side plates 11 on the lower surface of the upper plate 10, and the distance between the centers of the inverted truncated cones 13 is also used as a container. The diameter of the finger flange 20 of the syringe barrel 3 is set to be slightly longer than that of the finger flange 20, and the taper of the inverted truncated cone 13 is the same as the taper of the tapered hole 23 of the upper enlarged diameter formed at the center of the finger flange 20; Inverted truncated cone 13
A through hole 16 extends from the truncated surface 15 to the upper surface of the upper plate 10. A ring-shaped protrusion 17 is provided upright around the through hole 16 on the upper surface of the upper plate 10, and a rectangular frame-shaped protrusion 18 is provided upright on the periphery of the upper surface of the upper plate 10. Of the frame-shaped projections 18 are set to be the same. However, the shape, material, and the like of the mounting plate 1 are not limited to the above-described embodiment.

An example of the container / syringe 3 is shown in FIG. 4 and has the same structure as that described with reference to FIG. 4 in the section of the prior art.

As shown in FIGS. 1 and 3, the container / injection syringe 3 has a finger hanging flange 20 disposed between the two side plates 11 of the mounting plate 1, and the outer peripheral edges of the lower surface of the finger hanging flange 20 are on both sides. The inner edge of each ridge 12 of the plate 11 is elastically contacted, the tapered hole 23 of the finger flange 20 is elastically contacted with the tapered surface of the outer peripheral surface 14 of the inverted truncated cone 13, and the finger flange 20 is attached to each of the side plates 11. Of the projection 12 and the outer peripheral surface 14 of the inverted truncated cone 13. Therefore, in the container / injection cylinder 3, the elasticity of the mounting plate 1 causes the tapered hole 23 of the finger hanging flange 20 to be attached to the mounting plate 1.
Is pressed against the outer peripheral surface 14 of the inverted truncated cone 13 and hermetically sealed.

By the way, in the embodiment, the finger hanging flange 20 is used.
And the taper of the tapered hole 23 of the upper diameter having a central portion,
Since the taper of the inverted truncated cone 1 is the same, the sealing of the tapered hole 23 is performed on the entire tapered surface, and the tapered hole 2 is sealed.
The sealing of 3 is ensured.

In the embodiment, since the outer peripheral surface 14 of the inverted truncated cone 13 has a taper, the insertion of the inverted truncated cone 13 into the tapered hole 23 of the finger hanging flange 20 is facilitated. Even if a manufacturing error occurs in the diameter of the tapered hole 23 sealed by the outer peripheral surface 14 of the truncated cone 13, the tapered hole 23 is reliably sealed.

When the outer peripheral surface 14 of the inverted truncated cone 13 and / or the inner peripheral surface of the tapered hole 23 of the flange 20 are coated with an elastic material such as rubber, The sealing of the tapered hole 23 is performed more reliably.

The opening 22 formed in the center of the finger-holding flange 20 of the container / injection cylinder 3 is formed as a tapered hole 23 in the embodiment.
However, the shape is not limited to this, and may be a straight round hole or the like.

The shape of the finger-holding flange 20 of the container / injection barrel 3 is circular in the embodiment, but is not limited to a circle, and has a width substantially equal to the diameter of the sleeve 21 and a four-sided shape. A substantially rectangular shape or the like, each of which is an outwardly projecting arc, may be used.

In the case where the shape of the finger hanging flange 20 is substantially rectangular, the longitudinal direction of the finger hanging flange 20 is disposed between the two side plates 11 of the mounting plate 1 so that
The container / injection cylinder 3 is attached to the attachment plate 1. However, when the shape of the finger hanging flange 20 is the above-described substantially rectangular shape, when the container / injection etc. 3 is rotated about the center line of the inverted truncated cone 13, the finger hanging flange 2 is eventually formed.
The lower surface of both ends in the longitudinal direction of 0 is disengaged from the inner edge of the ridge 12 of the side plate 11, and the container / injection 3 is detached from the mounting plate 1. Accordingly, in order to prevent the container / injection barrel 3 from coming off the mounting plate 1 by hindering the rotation of the container / injection barrel 3, a position along the longitudinal center line of the mounting plate 1 on the lower surface of the mounting plate 1. And inverted truncated cone 13
A baffle plate is placed in a position parallel to the short side of the mounting plate 1 on both sides or one side of the flap, and the distance from the center of the inverted truncated cone 13 to the baffle plate is less than half the length of the longest width of the finger hanging flange 20. It is necessary to take measures such as setting a long length and hanging a baffle plate.

The filter 2 arranged on the upper surface of the ring-shaped projection 17 of the mounting plate 1 allows a sterilizing gas such as ethylene oxide gas or steam to pass therethrough to remove bacteria, dust and the like. Has the characteristics
The through hole 16 is made of synthetic paper or non-woven fabric made of a dust-free material, and is surrounded by a ring-shaped projection 17.
As shown in FIG. 2, portions A over the entire circumference of the upper surface of all the ring-shaped projections 17 erected on the mounting plate 1 are individually heat-sealed to reliably seal It is attached to the attachment plate 1 by a seal.

As described above, the embodiment uses the mounting plate 1
The tapered holes 23 of the finger hanging flanges 20 of all the container / injection cylinders 3 attached to the mounting plate 1 are individually pressed against the outer peripheral surface 14 of the inverted truncated cone 13 of the mounting plate 1 by the elasticity of the mounting plate 1 and hermetically sealed. , Inverted truncated cone 1
All the through holes 16 penetrating from the truncated surface 15 of FIG. 3 to the upper surface of the upper plate 10 of the mounting plate 1 are individually sealed by the filter 2. For this reason, in this embodiment, sterilization is performed with a sterilizing gas such as ethylene oxide gas or steam after packaging, but foreign substances such as bacteria, dead bacteria, and dust adhering to the packaging material are decompressed and heated. The foreign matter does not enter the outer cylinder 26 of the container / injection cylinder 3 even when the packaging material is peeled off from the packaging material by a sterilization operation that repeats pressure or a handling operation of the package. Therefore, in the embodiment, the inside of the outer cylinder 26 of the container / injection cylinder 3 filled with the injection solution is kept in a sterile and dust-free state from the time when the container / injection cylinder 3 is packed to the time when the container / injection cylinder 3 is taken out of the package.

The location of the mounting plate 1 to which the filter 2 is heat-sealed is not limited to the upper surface of the ring-shaped projection 17, but may be the upper surface of a rectangular frame-shaped projection 18 on the upper surface of the upper plate 10. However, when the filter 2 is heat-sealed on the upper surface of the frame-shaped projection 18 or the like, the upper surface of the ring-shaped projection 17 is also heated to surely prevent the foreign matter from entering the outer cylinder of the container / syringe. Desirably it is sealed.

The method for attaching the filter 2 to the attachment plate 1 is not limited to the method using heat sealing. A frame having a space having a width and length slightly longer than the width and length of the mounting plate 1 may be created, and the filter 2 may be interposed between the frame and the mounting plate 1 for mounting.

The mounting plate 1 is provided with a push-up force or a push-down force acting on the container / injection cylinder 3 until each of the ridges 12 of the two side plates 11 is detached from the finger hook flange 20 in order to attach / detach the container / injection cylinder 3. The elasticity is selected as a numerical value that allows the ridges 12 of the both side plates 11 to be expanded, and the tips of the ridges 12 are rounded and chamfered. Therefore, the container / syringe 3 can be easily attached to and detached from the mounting plate 1.

By the way, a slit extending from the lower end of the side plate 11 to the lower surface of the upper plate 10 is provided on both side plates 11, and the slit is formed between the finger hook flange 20 of the container / injection barrel 3 and the side plate 11
When the contact point with the ridge 12 is arranged between the slits, the elasticity of the side plate 11 is constant even when the mounting position of the container / injection cylinder 3 is at the end or the center of the side plate 11. Therefore, attachment / detachment of the container / injection cylinder 3 to / from the mounting plate 1 is facilitated. However, the shorter the distance between the slits, the lower the elasticity of the side plate 11 sandwiched by the slits,
Since the sealing by the elastic contact between the tapered surface of the tapered hole 23 of the finger hanging flange 20 and the outer peripheral surface 14 of the inverted truncated cone 13 becomes insufficient, it is necessary to appropriately select the elasticity of the side plate 11 depending on the distance between the slits. is there.

The above-described embodiment is composed of three components, namely, the mounting plate 1, the filter 2, and the container / injection barrel 3. The filter 2 is mounted on the upper portion of the mounting plate 1, and the container / injection barrel 3 is attached. Inner edge of each ridge 12 of both side plates 11 of mounting plate 1 and inverted truncated cone 13
, And is compact because the above-mentioned three components are assembled so as not to produce a useless space.

Further, since the filter 2 is attached to the upper part of the attachment plate 1 in a sheet form without being made into a bag form, the work of attaching the filter 2 becomes easy, and the single container / injection cylinder 3 is used. The surface area of the filter 2 required for packaging is reduced, and the syringe 2 is also used as a container for foreign substances such as bacteria and dust brought into the package by the filter 2.
The relative number for one is reduced.

[0049]

(A) Even if foreign substances such as bacteria, dead bodies of bacteria, dust and the like adhering to the packaging material are peeled off from the packaging material by a sterilization operation in which decompression and pressurization are repeated or handling of the package, etc., the container is also used as a container. The foreign matter does not enter the inside of the outer cylinder 26 of the injection cylinder 3. Therefore, the inside of the outer tube 26 of the container / injection cylinder 3 filled with the injection liquid is kept in a sterile and dust-free state from the time when the container / injection cylinder 3 is packaged to the time when the container / injection cylinder 3 is taken out of the package.

(B) Since the outer peripheral surface 14 of the inverted truncated conical body 13 has a taper, even if a manufacturing error occurs in the inner diameter of the opening 22 of the container / injection cylinder 3 sealed by the outer peripheral surface 14, The opening 22 is securely sealed, and the insertion of the inverted truncated cone 13 into the opening 22 is facilitated.
