Description

  TECHNICAL FIELD The present invention relates to a cap with a tamper-evident prevention and separation / recovery function, in which a lid is opened and closed via a hinge on a cap body to be opened by a pull ring, and it is difficult to tamper with tampering in a distribution process, and is easily separated and collected from a container body after use It is.

  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: 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 invention of the present invention is a cap in which a lid is connected to a rear portion of a cap body opened by a pull ring via a hinge so as to be openable and closable. A tamper-evident band for forming a protruding portion provided in the center of the tamper-resistant band, and a plurality of pieces arranged in a circumferential direction at substantially equal intervals, with the protruding portion facing the hinge side of the cap body. Connected by a fragile small bridge, and among these fragile small bridges, one fragile small bridge provided at the rear portion of the left peripheral wall of the cap body has a triangular apex angle at the tip and a horizontal cross-sectional shape. In this case, the separation cutting knob is inclined rearward and has a notch line on the left side and protrudes from the peripheral wall, and the vertical thin wall weakness reaches the lower end of the peripheral wall of the cap body from the left side of the lower end side of the separation cutting knob. Forming a slender thin line of weakness that slopes forward from the right end of the lower end side of the sorting cutting knob and reaches the lower end of the peripheral wall of the cap body, and from the upper edge of the right side of the sorting cutting knob A thin thin line of weakness is formed along the upper end of the peripheral wall of the cap body to the front side in the circumferential direction to a predetermined position, and the protruding portion of the band for preventing unauthorized opening is formed in the front portion of the lid on the opposite side of the hinge An opening / closing collar that can be accommodated on the inside of the opening / closing collar protrudes, and a fitting recess is provided on the outer periphery of the upper surface of the opening / closing collar to fit the fitting protrusion of the tamper-evident band. It is a cap with an unauthorized opening prevention and a separate collection function.
