ITEM 1.  SECURITY AND ISSUER

         This Statement on Schedule 13D (this "Statement") relates to the Common
Stock, $0.01 par value (the "Common Stock"), of U.S. Can Corporation ("U.S. Can"
or the "Company"), a Delaware corporation and the associated preferred share
purchase rights of the Company. The address of U.S. Can's principal executive
offices is:

                              U.S. Can Corporation
                               900 Commerce Drive
                            Oak Brook, Illinois 60523


ITEM 2.  IDENTITY AND BACKGROUND

         Schedule A hereto and incorporated by reference herein lists each of
the persons filing this Statement (each a "Reporting Person"), and his, her or
its business address, principal occupation or business, and citizenship or state
of organization. Schedule B hereto and incorporated by reference herein lists
each of the persons enumerated in Instruction C of Schedule 13D, and his, her or
its business address, principal occupation or business, and citizenship or state
of organization.

         During the last five years, no Reporting Person or person listed on
Schedule B hereto has been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors) or was a party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of
such proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

         This Statement is being filed because there may be deemed to have been
the formation of a "group" (as contemplated by Rule 13d-5(b) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) consisting of
the Reporting Persons. Each of the Reporting Persons expressly declares that
this Statement shall not be construed as an admission that any such "group" has
been formed or that any such Reporting Person is, for purposes of Section 13(d)
or 13(g) of the Exchange Act, the beneficial owner of any shares of Common Stock
owned by any other Reporting Person. Each Reporting Person has provided its own
information and disclaims responsibility for information provided by any other
Reporting Person.


ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         This Statement does not report the acquisition of any additional shares
of Common Stock by any of the Reporting Persons except insofar as any of the
Reporting Persons may be deemed for purposes of Section 13(d) or 13(g) of the
Exchange Act to have acquired beneficial ownership of the shares of Common Stock
held by any other Reporting Person because there may be deemed to have been the
formation of a "group" (as contemplated by Rule 13d-5(b)). As such, there is no
use of funds or other consideration to report. Each of the Reporting Persons
expressly declares that this Statement shall not be construed as an admission
that any such "group" has been formed or that any such Reporting Person is, for
purposes of Section 13(d) or 13(g) of the Exchange Act, the beneficial owner of
shares of Common Stock owned by any other Reporting Person.


ITEM 4.  PURPOSE OF TRANSACTION

         On June 1, 2000, Pac Packaging Acquisition Corporation, a Delaware
corporation ("Pac"), and the Company entered into an Agreement and Plan of
Merger (as amended on June 28, 2000, the "Merger Agreement") to effect a
recapitalization of the Company. Pac is a newly formed corporation organized by
Paul W. Jones, Chairman and Chief Executive Officer of the Company, John L.
Workman, Chief Financial Officer of the Company and Berkshire Partners LLC, a
private equity firm ("Berkshire
<PAGE>   27



Partners"). Pursuant to the terms and subject to the conditions of the Merger
Agreement, Pac will be merged with and into the Company (the "Merger") and each
share of Common Stock outstanding at the effective time of the Merger will be
converted into the right to receive $20.00 per share in cash, except for certain
shares of Common Stock held by the Reporting Persons and for shares of Common
Stock held by stockholders who perfect their appraisal rights under Delaware
law. The shares of Common Stock held by the Reporting Persons and the shares of
common stock of Pac will be converted into capital stock of the surviving
corporation as described in the Merger Agreement. The consummation of the Merger
is subject to a number of conditions, including approval of the Merger by the
Company's stockholders and the receipt of financing and governmental approvals.

         If the Merger is consummated, it is expected that the Company will
cease to be a public company and that the Common Stock will cease to be traded
on the New York Stock Exchange and the only remaining stockholders of the
Company immediately after such consummation would be the Reporting Persons. It
is also anticipated that the Common Stock would become eligible for termination
of registration under the Exchange Act upon consummation of the Merger.

         Upon consummation of the Merger, it is expected that the board of
directors of the Company will be made up solely of directors designated by the
Reporting Persons. It is also anticipated that the current management of the
Company will continue to be the management of the Company after consummation of
the Merger.

         In connection with the Merger, it is anticipated that certain
affiliates of Berkshire Partners will acquire a controlling equity interest in
the Company (approximately 77%) in exchange for an investment of up to $170
million. On June 20, 2000, each of the Reporting Persons who currently holds
shares of Common Stock in the Company agreed to participate in the Merger by
retaining at least a portion of their present equity interest in the Company
after consummation of the Merger. In connection with the Merger, the following
Reporting Persons will be selling the enumerated portion of their shares of
Common Stock on the same terms available to the other stockholders of the
Company.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER


         For a description of the Merger Agreement, see below and Item 4 of this
         Statement.

Initial Stockholders Agreement

         In connection with the Company's initial public offering of Common
Stock in March 1993 (the "IPO"), the Company entered into an agreement (the
"Initial Stockholders Agreement") with its stockholders immediately prior to the
IPO pursuant to which each of Salomon Smith Barney Inc. (successor-in-interest
to Salomon Brothers Inc.) and Messrs. Poma and Soler, for so long as each of
them owns beneficially at least 175,000 shares of Common Stock, has the right to
submit a name to the board of directors of the Company to be included in the
slate of nominees for election to the board of directors. The Initial
Stockholders Agreement provides that, if a designee ceases to serve for any
reason, the party who submitted the name of such designee has the right to name
a successor for approval by the board of directors to fill the vacancy so
created, and any director so chosen shall hold office for a term expiring at the
Company's annual meeting at which the term of office of the class to which such
director has been added expires, or until such director's successor has been
duly elected and qualified. The Initial Stockholders Agreement also provides for
certain registration rights.
<PAGE>   32



Proposed New Stockholders Arrangements

         All of the shares of U.S. Can common stock and U.S. Can preferred stock
outstanding immediately after the recapitalization will be subject to the terms
of several new stockholders agreements to be entered into by all of the common
and preferred shareholders of the Company (the "New Stockholders Agreements").
Pursuant to the terms of the New Stockholders Agreements, sixty percent of the
common stock of U.S. Can that will be held by Mr. Jones, Mr. Workman, Mr. Ford,
Mr. Farley, Mr. Scrimo, Ms. Derbyshire and Mr. Kirk immediately after the Merger
will be subject to a two-year vesting period. The remaining forty percent of the
common stock of U.S. Can that will be held by such management stockholders will
be subject to both a five-year vesting period and a requirement that the
affiliates of Berkshire Partners who are shareholders shall have achieved at
least a 25% annualized internal rate of return on their equity investment in
U.S. Can as determined at the time such shareholders sell their equity
investment in U.S. Can. The shares of common stock of U.S. Can held by
management after the Merger will be subject to certain repurchase rights and
obligations.

         U.S. Can will establish an incentive stock option plan providing for
the grant of time and performance vesting options to U.S. Can employees
exercisable, in the aggregate, for up to 5.75% of the common stock of U.S. Can
on a fully diluted basis. Of these, 4.35% will be subject to 5-year time-based
vesting only and 1.40% will be subject to 5-year time-based vesting and a
requirement that the affiliates of Berkshire Partners who are shareholders shall
have achieved at least a 25% annualized internal rate of return on their equity
investment in U.S. Can as determined at the time such shareholders sell their
equity interest in U.S. Can. Mr. Jones, Mr. Workman, Mr. Scrimo, Ms. Derbyshire
and Mr. Kirk will receive options exercisable for 0.50%, 0.75%, 0.60%, 0.375%
and 0.375% of the outstanding common shares of U.S. Can, respectively. The
remaining options will be issuable to other employees of U.S. Can. The options
to purchase shares of common stock of U.S. Can held by management after the
Merger, and the shares issued upon their exercise, will be subject to certain
payment and repurchase rights and obligations.

         The preferred stock to be issued by the Company will have an initial
aggregate principal amount of up to $113,333,333 and will be non-voting and
non-convertible and will have cumulative cash dividends of 10% per year, payable
only as, if and when declared by the board of directors.

         So long as U.S. Can is not paying default interest under any of its
financing arrangements, a supermajority vote of the common stockholders will be
required to approve and adopt mergers, acquisitions, charter or bylaw
amendments, extraordinary capital expenditures, extraordinary borrowings,
dividends, stock issuances and certain other matters. A supermajority vote will
be required at all times for a financial restructuring that treats the
management stockholders differently and adversely from the rest of the common
stockholders.

         No stockholder will be permitted to transfer any shares within three
years of the reorganization except for certain permitted transfers. After such
three-year period, shares may be transferred only pursuant to a right of first
refusal in favor of U.S. Can and, if U.S. Can declines its right, the other
stockholders on a pro rata basis. If the right of first refusal is not
exercised, then all other investors will be given the option to sell their
shares on a pro rata basis on the same terms and conditions to the same buyer
except that stockholders owning four percent or less of the outstanding shares
may transfer such shares without giving other holders the right to sell on the
same terms and conditions as long as they have complied with the right of first
refusal.

         If any of the stockholders, individually or collectively, determine to
sell a significant portion of the then issued and outstanding shares of U.S.
Can, then at the election of such stockholders, each of the other stockholders
will be required to sell the same proportion of their stock as the initiating
stockholders
<PAGE>   33
on the same terms and conditions. Stockholders will have pre-emptive rights to
subscribe for newly issued shares on a pro rata basis, subject to certain
exclusions. Stockholders will have registration rights with respect to their
shares. Most of the restrictions contained in the stockholders agreement will
terminate upon consummation of a qualified initial public offering of common
stock by U.S. Can or a change in control of U.S. Can.

         Except as described in this Item 6 or in Item 4 or Item 5 of this
Statement, none of the Reporting Persons and, to the knowledge of the Reporting
Persons, none of the persons listed on Schedule B hereto, has any contracts,
arrangements, or understandings (legal or otherwise) between or among themselves
or with the Company or any other person with respect to any securities of the
Company.

Financing

         Pac has received a commitment letter from Berkshire Partners to
purchase on the closing date of the Merger equity securities of Pac representing
100% of Pac's common stock for an aggregate amount of up to $170 million.
Berkshire Partners may allocate a portion of its investment to other investors
including the management team of U.S. Can and certain other investors of U.S.
Can. The commitment letter provides that Berkshire Partners expects to subscribe
for a minimum of $100 million of such equity. Berkshire's obligations under the
commitment letter are subject to certain conditions, including the execution of
the Merger Agreement, the satisfaction of all conditions precedent to Pac's
obligations under the Merger Agreement, the closing of the Merger, the funding
of the loans described below, and the execution and delivery of mutually
acceptable documentation. Berkshire Partner's commitment terminates if the
Merger is not completed on or before October 31, 2000.

         Pac and Berkshire Partners have received a commitment letter from Bank
of America, N.A., Banc of America Securities LLC, Citicorp North America, Inc.
and Salomon Smith Barney Inc. to provide up to $450 million in senior secured
financing to fund a portion of the Merger consideration and related expenses and
to provide for the ongoing working capital needs of United States Can Company,
the borrower and a wholly owned subsidiary of U.S. Can. It is expected that the
senior secured credit facility will be in the form of a $300 million term loan
facility and $150 million revolving facility. The term and revolving facilities
are expected to have terms ranging from six to eight years and bear interest at
floating rates.

         The senior secured credit facility will be secured by a first priority
lien on substantially all of the outstanding capital stock and assets of United
States Can Company and its domestic subsidiaries. Additionally, U.S. Can and all
of its domestic subsidiaries except for United States Can Company will guarantee
the loans under the senior secured credit facility. Moreover, certain designated
foreign subsidiaries of U.S. Can will also guarantee the loans extended to them.
The senior secured credit facility will contain customary financial and other
covenants, including restrictions on liens, mergers, consolidations and sales of
assets, the payment of dividends and the incurrence of other debt.

         U.S. Can expects that United States Can Company will also issue $150
million of senior subordinated notes. The interest rate and other terms of the
senior subordinated notes will depend upon interest rate and market conditions
at the time of their issuance. However, it is anticipated that the senior
subordinated notes will have the following features: a maturity of 10 years from
the issue date, be unsecured obligations and rank senior to all subordinated
indebtedness of United States Can Company, be subordinated to any senior
indebtedness of United States Can Company, including the senior secured credit
facility, and be guaranteed by U.S. Can and by all domestic and foreign
subsidiaries of United States Can Company and U.S. Can which guarantee the
senior secured credit facility. U.S. Can expects that the senior subordinated
notes will also contain covenants that are customary for this type of financing,
including restrictions on dividends, stock repurchases, liens, indebtedness,
affiliate transactions, assets sales and mergers. It is expected that the senior
subordinated debt securities will be issued in a private offering to be
consummated prior to or concurrently with the Merger.






<PAGE>   34
         If the $150 million senior subordinated debt offering is unable to be
completed due to then current market conditions, Pac and Berkshire Partners have
obtained a bridge loan commitment to provide this portion of the financing. Pac
and Berkshire Partners have received a commitment letter from Bank of America
Bridge LLC, Citicorp North America, Inc. and Salomon Smith Barney Inc. to
provide up to $150 million in interim financing in place of the senior
subordinated notes. United States Can Company would be the borrower under this
bridge loan facility. It is expected that the bridge loan facility will have the
following features: a one-year term, subject to certain extension rights, be
unsecured obligations and rank senior to all subordinated indebtedness of United
States Can Company and subordinated to any secured indebtedness of United States
Can Company, including the senior secured credit facility, pay interest at
floating rates, be guaranteed by the domestic and foreign subsidiaries of United
States Can Company and U.S. Can which guarantee the senior secured credit
facility, and contain customary financial and other covenants for this type of
financing, including restrictions on dividends, stock repurchases, liens,
indebtedness, assets and mergers.

         The commitments for the senior secured credit facility and the bridge
loan facility are subject to customary conditions, including the preparation and
execution of definitive loan agreements and related documents and the absence of
any material change in the business of Pac, U.S. Can and, for the senior secured
credit facility, United States Can Company. The commitments expire on October
31, 2000.

Note Repurchase and Consent

         Pursuant to the terms of the Merger Agreement, the Company and Pac have
agreed to take all necessary actions to repurchase some or all of the Company's
outstanding 10 1/8% senior unsubordinated notes and to obtain the consent of at
least a majority of the principal amount of such notes outstanding to permit the
Merger and related financings and other transactions to be effected without
constituting a breach or default under the original indenture.
