A pantograph (or “pan“) is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead catenary wire.
- Slider on the lid to prevent spillage
- Insulated material to keep the coffee warm
- Tiny air hole on the lid to help the coffee flow better
- Lip on the lid to making drinking drip-free
- Plastic insulation avoids the nasty metallic taste of metal lining
- The mug HAS to remain vertical – on its side, coffee leaks out the air hole and slots in the lid slider. On a train or tube journey, it’s almost inevitable that a mug in your bag, on your lap, or in the drink holder of your rucksack is going to go horizontal at some point. It could be on a busy train trying to balance the things in your possession or when you get to the office and put your bag down or arrive home and place it on the floor or counter. There are a lot of scenarios. My point is, coffee drips in your bag or on your clothes are annoying!
- Cleaning – the lid is difficult to clean and requires scrubbing around the slider part of the lid where coffee congregates and hardens.
- Incentivise – bigger discounts (most already have small) and advertise mug reuse more
- Make people aware of the damage
- Make them dead easy to clean – nobody likes a stinky coffee mug
- Reminders – people forget to bring their mug into the shop
I was buying a few things from a Sainsburys local at lunch time. I used the self service checkout stand and scanned my items in. I then “used the touch screen to complete my purchase” as the voice said out loud to me. I inserted my card but didn’t press the “debit/credit card” button. I got an error: “please press the card button”. Clearly the machine is aware that I’ve inserted my card because it’s giving me an error message. The question is, what does it need to give me an error? When it detects that I’ve inserted my card, it should jump to the card payment option automatically and allow me to enter my PIN. There are unneeded steps in this process.
