Description

The present invention relates to a cap holder that is widely used as a container for drinking water, juice, and the like and that can hold a cap temporarily after removing a lid (cap).

In the case of a cap that has already been published, a rotation mechanism that can rotate the cap body is not provided, and the cap body is coupled directly to the ring that supports the bottle on the bottle side. Even the ring that supports the cap will rotate. In addition, since the cap body is lifted when opening, the connecting band needs to be the minimum length, but if the elasticity of the connecting band is weak, the connecting band entangles the side of the cap when opening and closing the cap. Thus, it is difficult to open and close because the rotation is transmitted to the ring with a delay, and the cap hits the mouth or cheek when drinking. On the contrary, when the elasticity of the connecting band is strong, the cap does not leave the spout even if the cap is opened. In this case, the tie band is sandwiched between fingers to drink. (See Patent Document 1)

Further, in the case of a beverage container with a cap holder, the beauty of the side surface of the bottle body is lost because a part of the side surface of the bottle body and the shape are changed to provide the cap holder on the bottle body. (See Patent Document 2)

Since the cap holder and the bottle body are manufactured separately, and the cap holder is attached so as to be sandwiched between the labels, the manufacturing process becomes complicated. (See Patent Document 3)

Since the cap holder and the bottle body are manufactured separately and carried separately, the holder may be lost. (See Patent Document 4)
