Mold for bottom of plastic material bottle, has space formed between two embedding parts, where space between embedding parts is greater than strategic place to allow flow of preserved residual air
Mold for bottom of plastic material bottle, has space formed between two embedding parts, where space between embedding parts is greater than strategic place to allow flow of preserved residual air
The mold has two vents or air exhaust ducts (5) that are arranged at a lower edge of one of embedding parts (1, 2). The ducts are arranged to reproduce residual air at a strategic place. A space is formed between the embedding parts, where the space between the embedding parts is greater than the strategic place to allow flow of preserved residual air. An independent claim is also included for a method for manufacturing a mold for bottom of a bottle.
