[Prior art]
Conventionally, when opening a bottle-type container or a screw-type lid at the mouth of a plastic bottle or bag-type container, it becomes very difficult to open depending on the tightening condition. It has become. Of these, a flat sheet is used as an opening aid by a simple operation, a cut is made in the center part of the rubber sheet, and the container cap part is pushed open by sticking to the cut and adhered to the side of the container cap. The container cap portion is twisted and opened using a rubber sheet portion (see, for example, Patent Document 1). In the case of a large-diameter cap such as a jam bottle, since the cut portion that is pushed open and closely contacts the side of the cap is large, the force applied to the opening can be transmitted to the cap sufficiently, but a small-diameter cap such as a gable roof liquid paper container with a spout In the case of the cap, there is a drawback that not only the cut portion to be adhered becomes small and the effect is small, but also the surrounding margin prevents the opening operation. In addition, it has a single function that only assists the turning operation for opening the cap. From the characteristics of the material of the rubber sheet, the pull ring of the unsealing part that is integrally provided inside the spout It did not have any opening assisting means by towing.
