What is the marble design purpose of "Pinball Soda"?
1872, Hiram Codd, an Englishman, invented a Codd bottle filled by machine and sealed with glass beads. In the operation of this design, the flavoring agent is first injected into the bottle, and then the bottle mouth is upward and injected into the carbonated water in one breath.
When the liquid is full, turn the bottle upside down, so that the glass beads will fall to the mouth of the bottle, because the pressure in the bottle is relatively high, and the glass beads can seal the mouth of the bottle under the action of gas pressure.

The design of Cod bottle also brings many problems. If you shake the bottle before opening it, it will have champagne effect. Recycled glass bottles will be difficult to clean because of marbles; When manufacturers recycle bottles, marbles are often taken away.
Children like to take glass balls out of bobo soda to play with. Glass marbles are a common collection among children, but bobo soda without marbles will make the shopkeeper very troublesome. Marbles with a diameter of only about 1.5 cm may also be eaten by young children.
Shops selling soda usually have a special bottle opener to press glass beads into the bottle. In the past, bottle openers were mostly made of iron, and they were hung at the door of the store with ropes for immediate purchase and drinking. Most empty bottles are left in the store for recycling.
Later, a plastic bottle opener was attached to each bottle, and the bottle mouth was wrapped with shrink film, which on the one hand prevented the marbles from being polluted, and on the other hand allowed customers to take them home.
