A plastic formed inflation mouth structure comprises a plastic formed body which is integrally formed with an inflation mouth by plastic injection molding. The inflation mouth includes an inflation apparatus passage and a restoration unit that are integrally formed. The inflation apparatus passage unit is formed with a notch for passage of an inflation apparatus to perform the inflation or deflation. The restoration unit applies an elastic restoration force onto the notch to make the notch assuredly enclose the inflation apparatus during the inflation and ensure a high airtightness when inflation is stopped. |
