Description

[0001]
[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening aid used when opening a container when drinking or extracting granular contents filled in a cup-shaped container.
[0002]
[Prior art]
2. Description of the Related Art It is well known that a stretchable straw used for sucking a beverage content is placed in a heat-shrinkable bag and attached to the side of a cup-shaped container together with the bag.
[0003]
This is because the tip of the straw has an acute angle, so the sharp tip penetrates a part of the lid when used, and is used as it is as a drinking spout (suction port). It has excellent functions such as a simple mounting function on the side of the cup.
[0004]
However, the above-described conventional cup-type container with a straw is mainly used as a container for storing a cold beverage or the like, and using this as a container for storing a hot beverage such as hot coffee, for example, requires a hot beverage. In some cases, there is no habit of drinking with a straw, and the cup type container with a straw is not suitable for hot beverages due to consideration of the heat resistance of the straw itself.
[0005]
On the other hand, in a general type of hot beverage-filled cup type container other than the above-mentioned cup type container with a straw, a part of the lid is peeled off from the flange on the upper surface of the cup, opened in a U shape, and used as a drinking spout.
[0006]
However, the operation of peeling off the lid adhered to the flange is not always easy, and an accident may occur in which the contents overflow due to camera shake at the time of peeling. In addition, the surface of the flange at the mark where the lid is peeled off is rough, and the rough feel when the lips touch is not good. In addition, the contents tend to adhere to the rough surface and remain, resulting in poor hygiene. Furthermore, in this case, as the lid is peeled off, the opening increases in a synergistic manner as the lid is peeled off, so that the area of the opening serving as a drinking mouth is not constant. In the case of such a spout, when trying to drink the content liquid by tilting the cup, there is a possibility that a larger amount than the expected amount may flow out of the opening, and there is a possibility that it will spill or overflow. is there.
[0007]
Even when the content of the container is a granular material, it is desirable that the shape and size of the opening be constant in order to keep the amount of ejection constant.
[0008]
The applicant of the present invention has previously proposed that the film-shaped lid is torn and opened by the opening aid attached to the cup-shaped container. The proposed opening aid facilitates opening of the cup-shaped container (see Japanese Patent Application No. 2002-135662). However, the opening can be performed more easily and the lid can be stably opened. Improvement of assistive devices is desired.
[0009]
