Long Bottle Necks
Long necked bottles are ideal for adult beverages because the bottle’s shape helps prevent discomfort when holding a beer for a longer period of time. Aside from that, the shape makes pouring the drink into a mug or glass easier. Unfiltered beers mostly come in bottles that have a more bulbous neck so sediments are captured. Long necks distribute heat all over the bottle as well.
Can Tabs
You might have wondered why tabs on soda cans have been designed in a way that they could easily get detached and fall inside the can. Actually, the tabs are intended to hold a straw. However, as you may already know, people these days usually just drink directly from a can. This is why some manufacturers have widened the mouths of cans to make this easier.
