Description

  The present invention relates to a hinge cap attached to the mouth of a container, and more particularly to a hinge cap that can be opened without using a pull ring.

  Conventionally, food containers that contain liquids such as dressings and seasonings are weakened on the inner periphery of the cap's dispensing tube that is attached to the container mouth to keep the container sealed until it is opened. There is a plug cap that opens the spout by opening the spout by pulling up the pull wall provided on the removal wall portion by tearing off the removal wall portion by providing a partition wall that defines the removal wall portion defined by the portion.

However, pulling up the pull ring and breaking the weakened part of the bulkhead requires a relatively large force (high, about 70N), and it is difficult for children and the elderly with weak fingertips to open the plug. There was something wrong.
Also, depending on how the pull ring is pulled up, the pull ring may be broken in the middle, which may be stressful for the user.
For this reason, a cap that can be opened not by a pull ring but by a rotation operation of a screwing portion of an overcap is known as a prior art (see, for example, Patent Document 1).
