One of the worst things to open are those bottles that hand soap come in. Y0u know, Palmolive do them. Carex if probably the brand leader. They seem to have replaced what I'd call 'traditional' cake soap. In Sainsbury's at least they have a wide selection of brands, including their own.They are locked to prevent them accidentally selling their contents when in transit. I presume. It can't be for any other reason. You have to turn the spouty sort of pouring tap-arrangement and this is supposed to open the bottle. But it never seems to work. Well, at least, not for me. Then, once it works, you just press downwards on this tap thing and the liquid soap inside the bottle is squeezed out onto your hand. Then, biggest niggle of all, towards the end of the life of the product, you get a little bit at the bottom of the bottle which you can never get out. It seems such a waste.Why can't the manufacturer make the clear tube within the bottle just that bit longer so it sucks up the little bit at the bottom of the bottle? It almost refuses to be removed when you squeeze down on the pump-thing.
Shower gel bottles can also be difficult to open. There you are, standing stark naked under the shower. It's taken you a while to set the temperature (yet another niggle this. I could write a few pages on this on it's own.) You decide to use the new bottle of shower gel. You reach for it, trying not to scald yourself in the process, or, if the temperature isn't right, freeze yourself in the cold water. They put a neat little hook on one end of the bottle, which is there so you can hang the bottle over a tap or other fitting on your shower. The other end is where the opening is, and it's so arranged that you have to get a bit of plastic to pull up with your finger or thumb. It's made to be so tight, so the liquid within the bottle doesn't leak out, but it's so difficult you just can't get it to open. Then, when you manage to get it open, you squeeze the contained fluid onto your sponge or flannel, and too much comes out and when you lather the gel over your body, you get left with so much foam it looks like a scene from one of those 1950's science fiction movies such as 'Quatermass.'
Biscuit packets are another bugbear. ('A cause of obsessive fear, anxiety or irritation.') Or niggle. They come in a packet with another innovation, which is supposed to make it easier to open said packet. A little tab which you pull and tears open the paper with a strip of material like string or plastic. Great if it works, but 99 out of 100 attempts and it fails miserably. Why not just go back to the old fashioned method of opening the packet? Then there's the innovation that has been bought in on such packets as for rice and other cooking ingredients. You open the packet and then there's a sticky sort of label which you use to reseal the packet. But it doesn't always stick to the surface of the packet once you've opened the packet. So, like the biscuit packet, somewhat redundant. And attempting to peel the sticky label off the packet in the first place is also very difficult because (as with Sellotape when you can't find the end.) it's next to impossible to find the edge to peel.
Going back to the subject of cellophane as I mentioned earlier on, how about such things as DVDs and CDs which come, fresh from the factory, but covered in cellophane and then you have the ordeal of opening the thing, finding the corner to get your finger nail under to start the peeling process or even finding the little tab that is meant to make the process easier.
