Accounting Policies [Abstract]
Basis of Presentation	The consolidated financial statements include the accounts of Crown Holdings, Inc. and its consolidated subsidiaries (the “Company”). The accompanying unaudited interim consolidated financial statements have been prepared in accordance with Form 10-Q instructions. In the opinion of management, these consolidated financial statements contain all adjustments of a normal and recurring nature necessary for a fair statement of the financial position of the Company as of September 30, 2024 and the results of its operations for the three and nine months ended September 30, 2024 and 2023 and of its cash flows for the nine months ended September 30, 2024 and 2023. The results reported in these consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. These results have been determined on the basis of accounting principles generally accepted in the United States of America (“GAAP”), the application of which requires management’s utilization of estimates, and actual results may differ materially from the estimates utilized. Certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP have been condensed or omitted. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. During the fourth quarter of 2023, the Company recast its segment reporting to reclassify European corporate costs that were previously included in Corporate and other unallocated items in the European Beverage segment. Prior periods have been recast to conform to the new presentation.
Recent Accounting and Reporting Pronouncements	Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board issued new guidance that requires incremental disclosures related to reportable segments. That standard requires disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of profit or loss. The title and position of the CODM and how the reported measure of segment profit or loss is used by the CODM to assess segment performance and allocate resources is also required to be disclosed. The standard also permits disclosure of additional measures of segment profit. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. As the guidance impacts disclosure only, it will not have an impact on the Company's financial results. These changes in disclosure will initially be reflected in the annual financial statement footnotes for the year ended December 31, 2024. In December 2023, the Financial Accounting Standards Board issued a final standard on improvements to income tax disclosures. The standard requires disclosure of specific categories within the effective tax rate reconciliation and details about significant reconciling items, subject to a quantitative threshold. The standard also requires information on income taxes paid disaggregated by federal, state and foreign based on a quantitative threshold. The standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The standard is applied prospectively with an option for retrospective adoption. The Company is currently evaluating the impact of adopting this standard on its disclosures.
