Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Gateway Plastics Acquisition On September 20, 2021, we acquired Gateway Plastics LLC, or Silgan Specialty Packaging, a manufacturer and seller of dispensing closures and integrated dispensing packaging solutions, such as a combined container and closure or 100% recyclable dispensing beverage pods, to consumer goods product companies primarily for the food and beverage markets. The purchase price for this acquisition of $483.8 million, net of cash acquired, was funded with revolving loan borrowings under our amended and restated senior secured credit facility, as amended, or the Credit Agreement. The purchase price is subject to adjustments for working capital, net indebtedness and seller's transaction expenses. The initial purchase price has been allocated to assets acquired and liabilities assumed based on estimated fair values at the date of acquisition using valuation techniques including the income, cost and market approaches, primarily using Level 3 inputs (as defined in Note 9). For this acquisition, we applied the acquisition method of accounting and recognized assets acquired and liabilities assumed at fair value as of the acquisition date, and we recognized goodwill of $200.7 million which is expected to be deductible for income tax purposes, a customer relationship intangible asset of $166.0 million with an estimated remaining life of 22 years and technology know-how of $3.4 million with an estimated remaining life of 5 years. The purchase price allocation is preliminary and subject to change pending a final valuation of the assets and liabilities, including property, plant and equipment and intangible assets.
