JP 2004-345709 A

  When the conventional container is used, the inner container holds the outer flange at the upper end sandwiched between the upper ends of the mouth of the outer container by the cap of the outer container, and holds the lower end of the trunk part through a plate-like spacer having no cushioning property. Since it supports on the bottom face of an outer container, there existed room for improvement in the buffer property of a perpendicular direction, and there existed a problem that the airtightness of a cap might be impaired.

  Therefore, in view of the problems of the prior art, the object of the present invention is to freely release the outer flange at the upper end of the inner container into the mouth of the outer container, and to form a bottom dome-shaped bottom portion through the cushioning protrusion. An object of the present invention is to provide a packaging container for tablets that supports the bottom surface of the outer container to improve the cushioning property in the vertical direction and does not cause the problem of airtightness of the cap.

  The configuration of the present invention for achieving the above object comprises a bottomed rectangular tube-shaped outer container having an upward-facing mouth portion, and a buffer inner container mounted in the outer container. A barrel having four sides corresponding to each side wall of the container, a downward dome-shaped bottom portion of the lower portion of the barrel, and a circular opening formed in the upper portion of the barrel; Each of them is in contact with the inner surface of each side wall of the outer container through a plurality of cushioning protrusions, the bottom is in contact with the bottom surface of the outer container through the cushioning protrusions, and the opening is connected to the upper outer flange. And forming a small gap between the inner periphery of the mouth portion. However, the small gap here refers to a gap having a small dimension that does not cause the tablet to be stored to enter or get caught.

  In addition, each surface of the trunk portion can be partitioned through a vertical groove.

  Further, the protrusion on each surface of the body part may be constituted by at least one of a conical protrusion and a protrusion having a cross-sectional angle, and the bottom protrusion may be constituted by a protrusion having a cross-sectional angle.

  Furthermore, a plurality of arc portions inscribed in the mouth portion and flat cutout portions can be alternately formed in the circumferential direction in the opening portion.

  According to the configuration of the invention, the inner container is freed by the outer flange of the upper end forming a small gap between the inner periphery of the mouth part in the mouth part of the outer container. There is no risk of damage. In addition, the inner container is supported by the bottom dome-shaped bottom part of the lower part of the body part through the cushioning protrusion, so that the inner container has a large vertical direction due to, for example, dropping the whole. Even when subjected to an impact, one or both of the dome-shaped bottom and cushioning protrusions are elastically deformed to effectively absorb the impact and protect the internal tablet, improving vertical cushioning Can be made. Even when the inner container is subjected to a horizontal impact, each surface of the trunk portion is in contact with the inner surface of each side wall of the outer container via a plurality of cushioning protrusions. Can be effectively protected.

  However, the outer container is a sealed container with a cap having sufficient rigidity. The inner container is made of a thin plastic that can be shrunk by applying a negative pressure. The inner container is shrunk smaller than the diameter of the outer container, inserted into the outer container, and inflated by blowing air into the outer container. To return to a predetermined shape. Such an inner container can be integrally formed by, for example, blow molding polyethylene resin into a thin wall.

  By separating each surface of the trunk portion through a concave groove in the vertical direction, the inside of the inner container can be smoothly contracted with a negative pressure inside. In addition, it is preferable to form each concave groove in the form which opens outside at an angle of about 90 ° in a V shape.

  As for the protrusions on each surface of the body part, it is preferable to properly use a conical protrusion and a protrusion with a cross-sectional angle in consideration of cushioning properties and convenience in molding. For example, conical protrusions can be provided on the parting line on two surfaces parallel to the separating direction of the split mold for molding, but in other places, a cross-sectional mountain shape extending in the separating direction of the split mold Shall be provided. Further, conical protrusions can be arranged at arbitrary positions on the two surfaces orthogonal to the split-type separation direction. The same applies to the bottom protrusion. However, in order to realize a sufficiently large cushioning property, it is preferable that the protrusions at the bottom are arranged with one or two or more ridges having a cross-sectional angle in the split mold separating direction.

  If a plurality of arc portions and flat cutout portions are alternately formed in the circumferential direction of the opening portion, the opening portion of the inner container can be stably positioned in the mouth portion of the outer container via the arc portion. When the inner container is inflated in the outer container, the air in the outer container can be vented through a gap formed between the portion and the inner periphery of the mouth.
