  Conventionally, unauthorized opening of merchandise at stores in the market, for example, the mouth and neck of a PET bottle (polyethylene terephthalate biaxially stretched blow-molded) is fitted with a cap connected to the cap body via a hinge. However, the cap lid is deliberately opened, and the pulling ring accommodated in the dispensing cylinder of the cap body is pulled to break the thin thin line of weakness provided on the sealing plate inside the dispensing cylinder. After opening the cap body, many mischiefs such as closing the lid to the cap body again and returning it to the store were often seen. Also, recently, due to environmental conservation problems, when disposing of used bottles, there has been an increasing momentum for collecting and collecting parts of different materials for each material. For this reason, many inventions and devices have been made so far with regard to caps having a function of preventing unauthorized opening of caps and caps that can be easily separated and collected from bottles during disposal.

  However, a cap that is attached to the mouth and neck of a bottle and has a function of preventing unauthorized opening during the distribution process and a separate collection function during disposal has not been developed yet.

  The present invention solves the above-mentioned problems during the distribution and disposal of the conventional cap, and has two functions of an unauthorized opening prevention function during the distribution process and a separate collection function during the disposal process. The present invention provides a cap with a tamper-evident prevention and separation / collection function.

That is, the first invention of the present invention is a cap in which a lid is connected to a rear part of a cap body opened by a pull ring via a hinge so that the lid can be opened and closed. The cap main body is provided with a flange for opening and closing, and a rectangular U-shaped tamper-resistant band body with an inner surface extending along the outer periphery of the peripheral wall on the outer side of the lower end of the peripheral wall on the left and right sides via a fragile small bridge. An engagement protrusion is provided at a corresponding position of the lid for tampering prevention of the lid on the upper end of the peripheral wall on the left and right side surfaces of the cap body, and the lid is covered with a tampering prevention band for the lid on the side wall of the cap body. An L-shaped notch is provided at a position so as to form a cutting knob part whose rear side reaches the upper end of the peripheral wall and whose front side reaches an intermediate position, and extends from the rear upper end of the cutting knob part to the upper end of the peripheral wall. To the predetermined position in the circumferential direction on the front side Thin line of weakness is formed, the cutting knob tamper evidence and separate collection function with cap from the front side upper end, characterized in that the formation of the vertical thin lines of weakness extending into the side of the thin line of weakness upward of It is.
