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 on the cap body again and returning it to the store as it was 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 part of a cap body opened by a pull ring via a hinge so as to be openable and closable. A plurality of tamper-evident band members that form a protruding portion for providing a wearing convex portion in the center, and are arranged at substantially equal intervals in the circumferential direction, with the protruding portion facing the hinge side of the cap body. Are connected by a brittle small bridge, and a left and right outer peripheral upper end edge is provided with a knob portion on the left side of the upper portion in the rear circumferential direction, and a separation cutting band having a notch line on the left side of the lower portion, A vertical thin line is formed that reaches the lower end of the peripheral wall of the cap body from the left end of the lower end side of the separation cutting band, and is inclined forward from the right end of the lower end side of the separation cutting band to the peripheral wall of the cap body Oblique thin reaching the bottom of Forming a line of weakness, forming a thin thin line of weakness along the upper edge of the peripheral wall of the cap body from the upper edge of the right side of the separation cutting strip to a predetermined position on the front side in the circumferential direction. An opening / closing collar that can be accommodated inside the protruding portion of the unauthorized tamper-preventing band is projected from the front portion on the opposite side of the hinge. A fitting recess for fitting with the fitting projection of the band is provided, and the separation cutting band is accommodated at the corresponding position of the separation cutting band of the cap body at the left rear outer periphery lower edge of the peripheral wall of the lid It is a cap with a tamper-evident prevention and separation collection function characterized by protruding the cover part to back in the peripheral direction.
