A mold for forming the vial and cap and for seating the cap on the vial prior to ejecting the vial from the mold is provided and includes a frame for the mold, a first mold half arranged on the frame, and a second mold half movable arranged relative to the first mold half so as to form a mold cavity

A mold for forming the vial and cap and for seating the cap on the vial prior to ejecting the vial from the mold is provided and includes a frame for the mold, a first mold half arranged on the frame, and a second mold half movable arranged relative to the first mold half so as to form a mold cavity therebetween. The mold produces a vial and cap including smooth radii provided at several locations to facilitate the seating of the cap on the vial.

A process for forming an aseptic vial with a cap, comprising the steps of: injecting a molten material into a mold cavity defined on one side by an end mold part and an interior mold part and on the other side by a second mold part wherein said interior mold part is in contact with said second mold

A process for forming an aseptic vial with a cap, comprising the steps of: injecting a molten material into a mold cavity defined on one side by an end mold part and an interior mold part and on the other side by a second mold part wherein said interior mold part is in contact with said second mold part; forming from the molten material a vial and cap with annular regions for interlocking with one another, said regions including rounded transition surfaces for accommodating each other, wherein portions of the vial and cap are formed between the interior mold part and the second mold part and between the end mold part and the interior and second mold parts; venting from the mold cavity gases that are released from the molten plastic during the injecting step; cooling the vial and cap to about 100°-120°F.; maintaining the interior of the vial in an aseptic condition within the mold; retracting the end mold part from the interior mold part to separate the end mold part from the vial and cap; pressing the interior mold part directly against the second mold part while retracting the end mold part from the interior mold part and the vial and cap to retain the vial and cap within the second mold part by holding said portions of the vial and cap between the second mold part and the interior mold part while the second mold part is in direct contact with the interior mold part; retracting the interior mold part from the second mold part and the vial and cap; sealing the cap on the vial by pivoting a pivotable mold part from an original position to a sealing position and back to the original position, so as to guide, by means of the rounded transition surfaces, the annular regions of the vial and cap for interlocking with one another; sensing when the pivotable mold part is in an original position; ejecting the vial from the mold; and returning the end and interior mold parts to the second mold part when the pivotable mold part is in the original position.
