Hi Rebekh ,
I am recreating your packages for the desired output.
CREATE OR REPLACE PACKAGE pack_str
AS
     TYPE type_refcur IS REF CURSOR;
     PROCEDURE str(char_in VARCHAR2,ans OUT type_refcur);
END pack_str;
CREATE OR REPLACE PACKAGE BODY pack_str
AS
     PROCEDURE str(char_in VARCHAR2,ans OUT type_refcur)
     IS
          lv_t varchar2(200);
     BEGIN
          lv_t := REPLACE(char_in,',',''',''');
          lv_t := 'select id,name from col_tab where dept_name in (''' || lv_t || ''')' ;
          OPEN ans FOR lv_t;
     END str;
END pack_str;
Note:-
Input Parameter char_in is a comma seperated value for dept_name
