[0001]
[Industrial application fields]
The present invention relates to an opening aid used for opening a container when drinking a beverage content filled in a cup-shaped container or taking out a granular content.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, it is well known that a stretchable straw used for sucking beverage contents is placed in a heat-shrinkable bag and attached to the side of a cup-type container together with the bag.
[0003]
Since the tip of the straw has an acute angle, the sharp tip penetrates part of the lid when in use, and it is used as it is as a drinking mouth. It has excellent functions such as a simple mounting function on the side of the cup.
[0004]
However, the cup-type container with a straw of the above-mentioned conventional example 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 is a hot beverage. There are cases where there is no habit of drinking with a straw, and the cup-type container with a straw is not suitable for hot beverages because of the heat resistance of the straw itself.
[0005]
On the other hand, in a general type hot beverage filling cup type container that is not the cup type container with a straw described above, a part of the lid is peeled off from the flange on the upper surface of the cup and opened in a U shape, which is used as a drinking mouth.
[0006]
However, the operation of peeling off the lid bonded to the flange is not always easy, and an accident may occur in which the contents overflow due to hand shaking during peeling. Further, the surface of the flange that has been peeled off from the lid is rough, and the rough feel when touched by the lips is not good. In addition, the contents easily adhere to the rough surface and remain unsanitary. Furthermore, in this case, the more the cover is peeled, the larger the opening becomes synergistically, so the area of the opening serving as a drinking mouth does not become constant. In the case of such a drinking mouth, if you try to drink the liquid contents while tilting the cup, a larger amount than the expected amount may flow out of the opening, and it may spill or overflow is there.
[0007]
Even when the contents of the container are granular, it is desirable that the shape and size of the opening be constant in order to make the amount of swing out constant.
[0008]
The applicant of the present invention has previously proposed that the film-shaped lid is cut and opened by an opening aid attached to the cup-shaped container. Although the cup-shaped container can be easily opened by the proposed opening aid (see Japanese Patent Application No. 2002-135662), the opening can be further facilitated and the lid can be opened stably. Improvement of assistive devices is desired.
[0009]
