Description

  The present invention is a hinge cap in which a lid is connected to the rear portion of the cap body through a hinge so that the cap can be opened and closed. The present invention relates to a cap with an unauthorized opening prevention function that can be found.

  Conventionally, a tamper-resistant opening of a product at a store in the market, for example, a mouth cap of a PET bottle (a bottle obtained by biaxial stretching blow molding of polyethylene terephthalate) has been screwed with a hinge cap connected to the cap body via a hinge. The cap lid is deliberately opened and pulled on the pull ring accommodated in the extraction cylinder of the cap body, and is provided on the sealing plate below the inside of the extraction cylinder. There were many mischiefs of breaking the annular thin line of weakness and opening the cap body, then closing the lid on the cap body again and returning it to the store as it was.

  However, since the above-mentioned conventional cap with a lid is the one in which the container is opened only after the sealing plate that seals the dispensing cylinder is opened by the pull ring, It was not taken. Caps with a function to prevent unauthorized opening are being developed, but even if they were opened illegally, it was difficult to understand from the appearance that they were opened illegally.

  The present invention solves the problems of the above-mentioned conventional cap, and when the lid is tampered with in the distribution process or at the storefront, the tampered evidence remains, and it is clear from the appearance that the tamper has been tampered with. The present invention provides a cap with an unauthorized opening prevention function that can be confirmed.

  That is, the present invention is a hinge cap in which a lid is openably and closably connected via a hinge to the upper rear end of the peripheral wall of the cap body that is opened by a pull ring, and an opening / closing knob is provided at the lower end of the peripheral wall of the lid opposite to the hinge. Protruding and connecting one tip of the tamper-evident connection band to the center tip position in the left-right direction of the opening / closing knob via a thin fragile wire, Connect the upper end of the outer periphery of the retaining ring with the retaining ring to the inner peripheral surface of the lower end of the peripheral wall via the thin fragile wire, close the lid to the cap body, and hook the retaining ring to the lower end of the peripheral wall of the cap body. It is a cap with a tamper-evident prevention function characterized by being sealed.
