It's hard for ladies without a strong man's hand. A beloved man is unlikely to be around the clock. Therefore, the fairer sex has to face problems that seem ridiculous to any man. In particular, it is often very difficult for a woman, especially an elderly woman, to open an ordinary plastic bottle of water.
DDDDdesign took care of the older generation, developing a number of models to make life easier for ladies. The first of them is "Gemeinsam sind wir stark", which translates as "Together we are strong." Each cap of such a bottle has a recess on its top and a suitable projection on the side. Insert the protrusion of one bottle into the recess of the second and get a lever. Those who have taught physics know that this way it is much easier to unscrew the naughty cap. Resembles a wrench.
"I can" (I can! It can be used as a glass, and in addition, it helps to open a bottle - after all, it is much easier to unscrew such a large "cork" than the usual small one. It has a ribbed surface, so that the hand will not slip.
PlusMinus (Plus or Minus) is based on, so to speak, folk recipes. Owners of weak fingers know this very well: when it is impossible to open a bottle or a can of canned food, you need to pry it underneath with something, so that air can penetrate inside. After that, the disobedient vessel will open much easier.
In addition, several special bags were made for older ladies to carry bottled drinks. Carry On (Carry On; a stable expression, but carry means "to carry") is a convenient carrying for four bottles, and in addition, the handle in this item is removable: if it is turned forty-five degrees, it comes unfastened, and it can also be used to open the bottle as lever. The fact that only 4 bottles fit into the bag is also important. Ladies are not allowed to carry weights.
Finally, Take it easy (again a play on words, a persistent expression meaning "calm down, slow down," and literally can be translated as "take it easy"). This is a simple handle for three bottles. She will not help to open these bottles in any way. But they are easy and convenient to carry, and then the carrying can be folded into one even thin layer of plastic, which can easily fit in a kitchen cabinet.
