Abstract: A tamper-proof plastic vial is rendered tamper-proof during transport to and from a specimen-receiving site. The vial comprises a container and cap molded together in one piece. The cap is inserted onto the container during the manufacturing phase and is secured thereto by a first destructible connector in the form of an arrow-like projection so that the integrity of the container is ensured until a specimen is received. Thereafter, a second destructible member in the form of a flexible one-way strip is attached to form a second destructible connection. The container carries an outer channel which receives a peripheral edge of the cap to establish a tortuous bacterial path and to resist accidental opening of the cap. The first destructible connection is created in response to a controlled shrinkage of the assembly during the cooling phase of manufacturing.

Abstract: A reclosable attachment for containers for permitting the contents of the container to be discharged from the container includes a flange member, a cylindrical extension that extends from one side of the flange member, and a cylindrical stem that extends from the opposite side of the flange member. A cap is connected to the flange member and is adapted to be engaged and disengaged with the cylindrical extension in order to permit or prevent the discharge of the contents from the container. A feature is also provided on the reclosable attachment for preventing someone from unknowingly tampering with the container and for preventing the cap from being accidentally opened. Several spaced apart ledges which extend radially outwardly from the outer peripheral surface of the stem can also be provided for maintaining the position of the attachment relative to the container.

Abstract: A tamper-proof container and cap assembly includes apertured flanges disposed on the container and cap, the apertures of which become substantially aligned when the cap is inserted onto the container. Integrally molded with one of the flanges is a locking strip designed for one-way passage through the aligned holes, whereby removal of the strip is possible only by permanent destruction thereof. Structure may be provided for preventing relative lateral movement between the flanges.
