Definitions

  • the present invention relates to a cylindrical vial, with a bottom for a medicine, in which an opening is closed by a rubber closure (needle-penetrable rubber closure) which can be penetrated therethrough with a syringe needle.
  • a rubber closure needle-penetrable rubber closure
  • a vial for a medicine is in the form of a cylinder with a bottom.
  • the vial is provided at its one end with an opening which is closed by a rubber closure made of a rubber material, such as butyl rubber, after the vial is filled with a predetermined quantity of liquid medicament.
  • a syringe needle is penetrated into the rubber closure to aspirate the liquid medicament into the syringe.
  • the internal liquid medicament of the vial must be completely transferred into the syringe.
  • a dosage of liquid medicament is contained in the vial, and hence, if the entirety of the liquid medicament contained in the vial fails to be aspirated, there is a possibility that the expected effect of the dosage of liquid medicament is not achieved.
  • the inventors have conceived that if the needle which is penetrated into a vial through a needle-penetrable rubber closure is automatically brought to the deepest or innermost portion of the vial on the center axis thereof, it is possible to easily aspirate the whole quantity of liquid medicament in the vial into the syringe.
  • a cylindrical vial having a bottom for a medicine, in which an open end of the cylindrical vial is sealed by a needle-penetrable rubber closure through which a needle can be penetrated, the cylindrical vial including a conical bottom end provided opposite to the open end, wherein the apex of the conical bottom end is located on a central axis of the cylindrical vial at the bottommost point inside the cylindrical vial.
  • a conventional cylindrical vial having a bottom is made of a resin material by blow molding.
  • the cylindrical vial is formed using an injection molding die assembly including a core pin, the core pin being in the form of a rod having a uniform diameter and having a conical front end.
  • Dies other than the core pin are not limited to a specific shape or structure and can be of any structure.
  • the cylindrical vial is formed using an injection molding die assembly including a core pin, the core pin being in the form of a tapered rod having a conical front end and having an outer diameter gradually increasing from the conical front end toward the other end thereof.
  • Dies other than the core pin are not limited to a specific shape or structure and can be of any structure.
  • the conical bottom end of the cylindrical vial preferably defines an angle in the range of 30° through 70° between the generatrix of the conical bottom end and the central axis of the cylindrical vial. If the angle is less than 30°, it is necessary to increase the length of the cylindrical vial in order to provide the same capacity as that of a conventional cylindrical vial, and there is a possibility that the needle cannot reach the deepest or innermost portion of the cylindrical vial. Furthermore, since the mass of resin of which the bottom portion of the cylindrical vial is increased, the cylindrical vial becomes heavy. If the angle exceeds 70°, no effect expected from the conical shape can be obtained.
  • a cylindrical vial for a medicine including an axial hollow portion, an open end connected to the axial hollow portion and a closed end opposite to the open end.
  • the open end is sealed by a needle-penetrable rubber closure through which a needle can be penetrated into the cylindrical vial.
  • the closed end includes a conical bottom end, the apex of the conical bottom end being located on a central axis of the axial hollow portion at the bottommost point inside the axial hollow portion.
  • the axial hollow portion is formed using an injection molding die assembly including a core pin, the core pin being in the form of a rod having a uniform diameter and having a conical front end.
  • the axial hollow portion is formed using an injection molding die assembly including a core pin, the core pin being in the form of a tapered rod having a conical front end and having an outer diameter gradually increasing from the conical front end toward the other end thereof.
  • the conical bottom end of the cylindrical vial defines an angle in the range of 30° through 70° between the generatrix of the conical bottom end and the central axis of the axial hollow portion.
  • FIG. 1 is a longitudinal sectional view of an embodiment of a vial for a medicine in which an open end is sealed by a needle stickable rubber closure, according to the present invention
  • FIG. 2 is an enlarged view of a lower portion of FIG. 1;
  • FIG. 3 is a schematic sectional view of an injection molding die assembly for producing a vial for a medicine, according to the present invention.
  • FIG. 1 shows a bottomed cylindrical vial 10 which is filled with a liquid medicament, according to an embodiment of the present invention.
  • the cylindrical vial 10 is long and elongated and is provided with a closed end and an open end 11 which is closed by a rubber closure (needle-penetrable rubber closure) 20 .
  • the rubber closure 20 is provided on its center portion with a reduced thickness portion 21 through which a needle of a syringe can be penetrated.
  • the rubber closure 20 is secured, in a liquid-tight fashion, to the open end 11 by a retainer (rubber closure holding member) 22 .
  • the axial hollow portion 12 of the bottomed cylindrical vial 10 has a rotationally symmetrical shape with respect to the axis 10 X of the cylindrical vial 10 and has a uniform diameter over the overall length thereof from the open end 11 to a conical bottom 13 thereof.
  • the conical bottom 13 is deepest at the apex of the cone located on the axis 10 X and gradually decreases the depth toward the periphery thereof.
  • the angle ⁇ (FIG. 2) defined between the generatrix of the conical bottom 13 and the axis 10 X is preferably in the range of 30° to 70°, from the viewpoint of facilitation of use, and is more preferably in the range of 40° to 60°.
  • the bottomed cylindrical vial 10 is made of a resin material by injection molding.
  • FIG. 3 schematically shows an injection molding die assembly.
  • the injection molding die assembly 30 is provided with a core pin (rod-like central die) 32 in the form of a rod whose diameter corresponds to the inner diameter of the axial hollow portion 12 and which has a conical front end 31 corresponding to the conical bottom 13 , and a pair of right and left split dies 33 and 34 which define therebetween a molding cavity 10 M for the bottomed cylindrical vial 10 , together with the core pin 32 .
  • At least one of the split dies 33 and 34 is provided with a gate 35 through which a molding resin material is introduced into the molding cavity.
  • Various split structures of the split dies 30 to define the molding cavity 10 M can be used, provided that the axial hollow portion 12 is formed by the core pin 32 , and that the core pin 32 is provided on its front end with the conical portion 31 corresponding to the conical bottom 13 .
  • the bottomed cylindrical vial 10 for a medicine which is formed by the injection molding die assembly 30 , is washed and is subject to other necessary operations. Subsequently, a liquid medicament is filled in the axial hollow portion 12 of the cylindrical vial 10 . Thereafter, the needle-penetrable rubber closure 20 is attached to the open end 11 of the cylindrical vial 10 and is secured thereto by a retainer 22 to seal the open end.
  • a needle 40 attached to a syringe is penetrated into the cylindrical vial 10 through the thin portion 21 of the rubber closure 20 .
  • the retraction (inward movement) of a plunger in the syringe causes the liquid medicament in the cylindrical vial 10 to be aspirated into the syringe.
  • the needle 40 is inserted up to the innermost portion of the cylindrical vial 10 , the front end of the needle 40 naturally moves to the apex of the cone of the conical bottom 13 while being guided by the conical surface. Since the liquid medicament in the cylindrical vial 10 is collected in the conical bottom 13 , substantially all of the liquid medicament in the cylindrical vial 10 can be aspirated by the syringe without needing to incline the cylindrical vial 10 .
  • the core pin 32 of the molding die assembly 30 shown in FIG. 3 has a uniform diameter, it is possible to provide the core pin 32 with a tapered peripheral surface for easy release thereof.
  • the core pin 32 can be in the form of a slightly tapered rod whose outer diameter is gradually increased from the conical end 31 toward the other end. The taper angle should be as small as possible.
