Description

  The present invention relates to a tamper-evident bottle for storing products for medical drugs that must be strictly used for specific use and products that are not intended to be accidentally swallowed by children, and more specifically, a special jig is provided. The present invention relates to an unauthorized opening prevention bottle that cannot open the bottle cap.

  As shown in FIGS. 9 and 10, the bottle main body (A) for storing contents such as a liquid has a neck (1), a shoulder (2) connected to the neck (1), and the shoulder. (2) Consists of a body part (3) connected to the body part (3) and a bottom part (4) connected to the body part (3). After filling the contents, the neck part (1) has a cap body (B). Is generally attached by screw fitting.

  Plastic bottles containing contents such as food and drinking water have been devised in various ways to prevent them from being opened illegally until they reach the consumer's hands.

  For example, a plastic bottle with a tamper-evident cap that guarantees that there has been no fraud such as taking out contents or mixing in foreign matter has become quite popular.

  That is, conventional tamper-evident bottles are generally given an emphasis on improving their plastic caps, and are generally provided with a tamper-evident prevention function that can be clearly recognized once opened. .

  In this way, the tamper-evident prevention bottle in which the structure of the plastic cap is mainly devised can be easily opened, and the purpose is to clarify whether or not the bottle has been opened once.

  For example, a plurality of breakable connecting pieces are projected from the lower end surface of the peripheral wall of the cap body, and a sealing portion composed of a cylindrical thick ring portion and a thin cylindrical portion is connected to the tip of the connecting piece, and the sealing portion There has been proposed a synthetic resin cap by a method in which the cap is heated and deformed and caulked to the neck of the bottle mouth (for example, see Patent Document 1).

  Next, a circular top surface and a cylindrical skirt hanging from the periphery of the top surface are provided, and a rupture line extending in the circumferential direction is formed on the skirt, and the skirt causes the skirt to It is divided into a main part above the break line and a pilaf proof skirt part below the break line.

  The rupture line is defined by a plurality of slits (grooves) extending in the circumferential direction and so-called bridging portions existing between the slits, and the pilfer proof skirt is mainly formed by the bridging portion between the slits. It is connected to the part.

  When such a cap is removed from the bottle mouth and opened, the breaking line is completely broken and the skirt is completely separated into the main part and the pilaf proof hem, and therefore after opening There has also been proposed a synthetic resin cap configured such that the pilaf proof skirt part remains in the bottle mouth part without leaving (see, for example, Patent Document 2).

The next is a bottle having a cap with a fragile portion as described above, and a synthetic resin having a structure that clearly shows that the fragile portion is crushed and the bottle is opened when trying to open the bottle. Produced caps have been proposed (see, for example, Patent Document 3).

  As described above, the ring that engages with the lower surface of the flange provided on the neck portion of the bottle body is connected to the peripheral side wall of the cap body via the easily breakable connecting piece. Mainly the proposal of the tamper-evident prevention bottle with a devised cap structure, such as the connecting piece being pulled and broken when removing the fitted cap body while rotating, and the once-breaking connecting piece cannot be rejoined is there.

Prior art documents are shown below.
