  However, in the conventional connector, the tip inserted into the container has a shape in which the tip of the cylindrical portion is inclined, and pressing the tip in the axial direction pierces the film that seals the port. It was configured as.

  Because the film for sealing the port portion has a structure in which a resin layer, an aluminum layer, and the like are laminated, the film may be stretched without being broken at the end of such a connector when pressed in the axial direction. As a result, the connector can not penetrate the film, or the connector may be penetrated incompletely to increase the flow resistance.

In particular, in the case where a low flowable container such as a semi-solidified nutrient contained in a flexible container is collected and used in a syringe, the portion having low flowability is discharged like a catheter tip syringe. The one with a thick side tip is used. In that case, since the connector having a large diameter is used according to the diameter of the syringe, even if the tip is pressed in the axial direction, a phenomenon in which the film is stretched without being broken easily occurs.
Therefore, it is necessary to take out the contents in the flexible container once to another container and suck it into a syringe before using it, which causes problems of hygiene such as contamination of foreign matter, and problems in work efficiency. There was also a risk that

  In the present invention, in order to solve such problems, the film can be easily and reliably pierced regardless of the thickness of the connection which pierces the film for sealing the port, and the film can be reliably inserted into the container It is an object of the present invention to provide a connector capable of communicating with an instrument of

As a result, the first connection portion 31 is semi-solidified The semi-solidified nutrient can be aspirated directly from the container 10 to the catheter tip syringe 20 by inserting the second connection 32 into the catheter tip syringe 20 while inserting the container 10 containing the agent. Therefore, the semi-solidified nutrient can be used by being directly stored in the catheter tip syringe without being transferred to another container, and the container 10 can be used for storing the semi-solidified nutrient in the catheter tip syringe 20. In this case, it is possible to reliably prevent foreign matter from being mixed in, and it is possible to carry out the storing operation hygienically. In addition, the work efficiency of the storage work can be improved.

  In the connector 30 of this embodiment, the amount of rotation of the connector 10 with respect to the port portion 12 of the container 10 is restricted to a range not exceeding 360 degrees, so the film 16 is cut by rotating the piercing portion 36 However, there is no fear that the produced cutting piece 16a may be detached, and the cutting piece 16a can be used safely.

The above embodiment can be appropriately modified within the scope of the present invention.
For example, in the above embodiment, the flexible container 10 is described as the container 10 into which the first connection portion 31 is inserted, but the present invention is applicable to other containers such as a hard container, for example, and a port portion There is no limitation as long as 12 is a container sealed by the film 16.
Moreover, although the said embodiment demonstrated the example which accommodates a highly viscous contained thing like a semi-solidified nutrient as a contained thing of the container 10, if it is a contained thing which has fluidity, it will not be specifically limited. The invention is equally applicable, for example, to low viscosity liquids.
Furthermore, in the above embodiment, a syringe has been described as the device connected to the second connection portion 32. However, for example, a device such as a tube, a discharge port, or a valve may be used. Not limited to the fitting, various connection methods such as screwing can be adopted.
In the above description, the female screw 33a is provided on the base 33 and screwed to the male screw 14a of the port 12 of the container 10. However, the method of mounting the base 33 and the port 12 of the container 10 is as follows. If it can mount | wear by rotating the base 33, it will not be limited in particular.
