	FILED PURSUANT TO RULE 13d-1(b) or 13d-2(b)



	Pursuant to the instructions in Item 7 of Schedule 13G,
Fidelity Management & Research Company ("Fidelity"), 82
Devonshire Street, Boston, Massachusetts 02109, a wholly-
owned subsidiary of FMR Corp. and an investment adviser
registered under Section 203 of the Investment Advisers Act
of 1940, is the beneficial owner of 21,770,284 shares or
14.167% of the Common Stock outstanding of Owens Illinois
Incorporated  ("the Company") as a result of acting as
investment adviser to various investment companies registered
under Section 8 of the Investment Company Act of 1940. The
number of shares of Common Stock of Owens Illinois
Incorporated owned by the investment companies at
December 31, 2005 included 815,637 shares of Common
Stock resulting from the assumed conversion of 859,380
shares of OWENS ILLINOIS $2.375 CV PFD (0.9491 shares
of Common Stock for each share of Convertible Preferred
Stock).

	Edward C. Johnson 3d and FMR Corp., through its
control of Fidelity, and the funds each has sole power to
dispose of the 21,770,284 shares owned by the Funds.

	Members of the family of Edward C. Johnson 3d,
Chairman of FMR Corp., are the predominant owners, directly
or through trusts, of Series B shares of common stock of FMR
Corp., representing 49% of the voting power of FMR Corp.
The Johnson family group and all other Series B shareholders
have entered into a shareholders' voting agreement under
which all Series B shares will be voted in accordance with the
majority vote of Series B shares.  Accordingly, through their
ownership of voting common stock and the execution of the
shareholders' voting agreement, members of the Johnson
family may be deemed, under the Investment Company Act of
1940, to form a controlling group with respect to FMR Corp.

	Neither FMR Corp. nor Edward C. Johnson 3d,
Chairman of FMR Corp., has the sole power to vote or direct
the voting of the shares owned directly by the Fidelity Funds,
which power resides with the Funds' Boards of Trustees.
Fidelity carries out the voting of the shares under written
guidelines established by the Funds' Boards of Trustees.

	Fidelity Management Trust Company, 82 Devonshire
Street, Boston, Massachusetts 02109, a wholly-owned
subsidiary of FMR Corp. and a bank as defined in Section
3(a)(6) of the Securities Exchange Act of 1934, is the
beneficial owner of  950,326 shares or 0.618% of the
Common Stock outstanding of the Company as a result of its
serving as investment manager of the institutional account(s).
The number of shares of Common Stock of Owens Illinois
Incorporated owned by the institutional account(s) at
December 31, 2005 included 58,180 shares of Common Stock
resulting from the assumed conversion of 61,300 shares of
OWENS ILLINOIS $2.375 CV PFD (0.9491 shares of
Common Stock for each share of Convertible Preferred
Stock).

	Edward C. Johnson 3d and FMR Corp., through its
control of Fidelity Management Trust Company, each has sole
dispositive power over 950,326 shares and sole power to vote
or to direct the voting of 950,326 shares of Common Stock
owned by the institutional account(s) as reported above.

	Fidelity International Limited ("FIL"), Pembroke Hall,
42 Crow Lane, Hamilton, Bermuda, and various foreign-based
subsidiaries provide investment advisory and management
services to a number of non-U.S. investment companies and
certain institutional investors.  FIL, which is a qualified
institution under section 240.13d-1(b)(1) pursuant to an SEC
No-Action letter dated October 5, 2000, is the beneficial
owner of 329,469 shares or 0.214% of the Common Stock
outstanding of the Company. The number of shares of
Common Stock of Owens Illinois Incorporated owned by the
institutional account(s) at December 31, 2005 included 58,180
shares of Common Stock resulting from the assumed
conversion of 61,300 shares of OWENS ILLINOIS $2.375
CV PFD (0.9491 shares of Common Stock for each share of
Convertible Preferred Stock).

	A partnership controlled predominantly by members of
the family of Edward C. Johnson 3d, Chairman of FMR Corp.
and FIL, or trusts for their benefit, owns shares of FIL voting
stock with the right to cast approximately 38% of the total
votes which may be cast by all holders of FIL voting stock.
FMR Corp. and FIL are separate and independent corporate
entities, and their Boards of Directors are generally composed
of different individuals.

	FMR Corp. and FIL are of the view that they are not
acting as a "group" for purposes of Section 13(d) under the
Securities Exchange Act of 1934 (the "1934" Act) and that
they are not otherwise required to attribute to each other the
"beneficial ownership" of securities "beneficially owned" by
the other corporation within the meaning of Rule 13d-3
promulgated under the 1934 Act.  Therefore, they are of the
view that the shares held by the other corporation need not be
aggregated for purposes of Section 13(d). However, FMR
Corp. is making this filing on a voluntary basis as if all of the
shares are beneficially owned by FMR Corp. and FIL on a
joint basis.
