Some of the products we use every day have various purposes and some parts that are unique and unusual as well. Many people are baffled by these parts’ purpose – for example, do you know what the small pockets on female underwear are for? Here are 6 products we use every day and the purpose of their specific parts:
- The pockets on your panties
The pockets on female underwear are added for better comfort. This layer is made of soft cotton and it’s not sewn down in order to make you more comfortable.
- The diamond-shaped holes on backpacks
These holes were used as a camping equipment for hiking and allow easier tying of the backpack.
- Bobbles on hats
This part on hats first appeared in the 19th century among French sailors. At that time, the cabins in the ships had a low roof, and the bubbles were added as a safety measure. Later, the bubbles were added on knitted hats as a unique detail. Nowadays, the bubbles are used solely as an aesthetic feature.
- Lines on trousers
Lines on the trousers first appeared in the later 19th century in Europe. After making a pair, the trousers were folded and sent on a long road to countries around the world. Even though they spent miles on the road, the trousers always had the lines. After a while, people accepted them and they’re now a part of every pair of trousers.
- Lines on toothpaste
Many people believe that the lines on the toothpaste represent the quality of the product, but they are actually bar codes. According to manufacturers, the bar codes are used by the machines that produce the packaging and cut the tubes.
- The hole on lollipop stick
The holes on lollipop sticks are there to make the candy fix to it easier. During manufacture, the hole is made in the stick and the lollipop is fixed on it afterward.
