Claims

[Scope of claim for utility model registration] A male thread provided on the outer peripheral surface of the mouth and neck portion 4 of the container 5,
In a tightening locking device for a cap 22 that screws together a female thread provided on the inner peripheral surface of the cap 22, the male thread is formed as a male tapered thread 12 whose width gradually increases with a tapered surface 11 on the lower side. At the same time, the female thread portion is connected to the tapered surface 31.
The locking protrusions 13 and 32 are formed as a female tapered threaded portion 21 whose width gradually increases as the cap 22 is tightened, and locking protrusions 13 and 32 are provided on both tapered surfaces 11 and 31 of the male tapered threaded portion 12 and the tapered threaded portion 21 to overcome each other when the cap 22 is tightened. The height of each locking protrusion 13, 32 is set to protrude along the axial direction of the neck portion 4 of the container 5.
Tapered surfaces 11, 3 on both sides of locking protrusions 13, 32
1. A tightening and locking device for a container cap, characterized in that a recess 14 is formed in the container cap so that the locking protrusions 13 and 32 have a height such that a clipping sound is produced when the locking protrusions 13 and 32 ride over each other.
