In plsql how can a function use an object declared in a package - oracle

Question

i have a package(that is in beta, just want to make it work):
CREATE OR REPLACE PACKAGE pkg1 AS
type pipeDefinition is record
(
str VARCHAR2(4000),
num NUMBER,
);
type pipeContainer is table of pipeDefinition;
FUNCTION f1(x NUMBER) RETURN
pipeContainer pipelined;
END pkg1;
and the package body
CREATE PACKAGE BODY pkg1 AS
FUNCTION f1(x NUMBER) RETURN
pipeContainer pipelined
IS
BEGIN
FOR i IN 1..x LOOP
PIPE ROW(pipeDefinition('i',i));
END LOOP;
RETURN;
END f1;
END pkg1;
my problems:
1if i try to run the above i get
"error at line:
PIPE ROW(pipeDefinition('i',i));
function pipeDefinition can not be found" (not exactly exactly what it said, but close)
2if i try to use pkg1.pipeDefinition instead i get the same error
"error at line:
PIPE ROW(pipeDefinition('i',i));
function pipeDefinition can not be found"
3if i try to add
type pipeDefinition is record
(
str VARCHAR2(4000),
num NUMBER,
);
type pipeContainer is table of pipeDefinition;
in the package body, it sais
"can not declare more than 1 pipeContainer
and more than 1 pipeDefinition"
4if i try to add
type pipeDefinition2 is record
(
str VARCHAR2(4000),
num NUMBER,
);
type pipeContainer2 is table of pipeDefinition2;
in the package body(and alter the pipeRow line with pipeDefinition2), it sais
"the object referenced is of a diferent kind as to the one the function is suposed to output"
5if i try to add 4 and make the function return pipeContainer2 pipelined it sais
"function mismatch package and body"
6if i try to add 6 and make function return pipeContainer2 pipelined in the package also i get
"pipeContainer2 not defined before using it " in the package creator
can anyone give me some hints?

Klas Lindbäck, you are my hero!
Solution:
CREATE OR REPLACE PACKAGE pkg1 AS
type pipeDefinition is record
(
str VARCHAR2(4000),
num NUMBER,
);
type pipeContainer is table of pipeDefinition;
FUNCTION f1(x NUMBER) RETURN
pipeContainer pipelined;
END pkg1;
and the package body
CREATE PACKAGE BODY pkg1 AS
FUNCTION f1(x NUMBER) RETURN
outrec1 pipeDefinition;
--removed: pipeContainer pipelined
IS
BEGIN
FOR i IN 1..x LOOP
--removed: PIPE ROW(pipeDefinition('i',i));
--newLines:
outrec1.str := 'a';
outrec1.num := i;
PIPE ROW(outrec1);
--endNewLines.
END LOOP;
RETURN;
END f1;
END pkg1;
and my new pointer function is finally complete! :"D
SELECT * FROM TABLE(pkg1.f1(5));
|str | num|
a | 1
a | 2
a | 3
a | 4
a | 5

Create or replace package pk2 as
type c1 is ref cursor return employees%rowtype;
type outrec is record (
var_num number,
var1 varchar2(50),
var2 varchar2(50));
type outrecset is table of outrec;
function f_trans (c2 c1) return outrecset pipelined;
end pk2;
create or replace package body pk2 as
function f_trans(c2 c1) return outrecset pipelined is
outrec1 outrec;
outrec2 c2%rowtype;
begin
loop
fetch c2 into outrec2;
exit when c2%notfound;
outrec1.var_num := outrec2.employee_id;
outrec1.var1 := outrec2.first_name;
outrec1.var2 := outrec2.last_name;
PIPE ROW(outrec1);
outrec1.var1 := outrec2.email;
outrec1.var2 := outrec2.phone_number;
PIPE ROW(outrec1);
END LOOP;
RETURN;
END f_trans;
END pk2;
please take hint from this code
data type for the record is not declared
