Direct drinking has become quite commonplace since the spread of PET bottled beverages, but when you give it to the public or small children, you hesitate a little. Even when drinking carbonated drinks or powdered medicine, it is easier to drink by transferring to a cup.
I found a "PET bottle cup" at the 100-yen shop "Can Do" that solves such problems.
This product is a cup that you can carry around by putting it on the mouth of a PET bottle. By attaching attachment parts to the cap part, the cup can be firmly fixed and will not come off even if the bottle is turned upside down.
When drinking, remove only the cup and pour. If you put your mouth on the bottle, it is difficult to store it hygienically, but if you do this, you can store the drink in the refrigerator. Thankfully, there are many bottles of water and tea these days, and it's hard to drink, which is helpful.
It can be used with PET bottles of various sizes, but the one closer to a cylinder is more stable. As a caveat, if the cup remains wet, it will drip, so after drinking it, wash it and dry it well, or wipe it with a wet tissue before returning it.
When used in combination with a PET bottle cover, it looks like a water bottle. From now on, it seems to be useful in outing scenes such as cherry blossom viewing and picnics!
