         [0122]    It is not intended the invention be limited to the specific embodiments shown and described. 
         [0123]      FIGS. 1 and 1   a  illustrate a prehung door and frame assembly  30  with two corner protector containers  10  positioned in the tipper right and left corners of the prehung door assembly  30  and container embodiment  100  positioned on the lower right ( FIG. 1 ) side i.e. the hinge jamb  32 . FIG.  1  shows the cavity side  39  and  FIG. 1 a    the door side of the prehung door and frame assembly  30 . In a prehung door assembly the door  34  is usually hung from the hinge jamb  32  with hinges  36  so the door  34  is flush to the edges of head jamb  31 , hinge jamb  32  and striker jamb  33  on one side of the assembly ( FIG. 1 a   ). Because of the width of the jambs a cavity  39  is formed on the other side of the assembly. The door  34  usually has predrilled holes  35  for mounting lock and handle. The three jambs have a stop  37  running parallel to their edges on the cavity side  39  to prevent the door from moving through the frame formed by the jambs when closed. Two of the corner protector containers  10  are shown mounted in the cavity  39 , one in the right upper corner and one in the left upper corner. Container embodiment  100  is shown mounted in the cavity  39  on the hinge jamb  32 . The corner protector container  10  is held in place when the corner protector container  10  is assembled over the jambs. It can be further secured with a shipping band  38 . In this embodiment the corner protector container  10  is rectangular, it could also be square. The length and width of the corner proctor container can range from about a few inches to about ninety percent of the length and width of the cavity  39 , The width of side walls  12  and  14  (W 1  and W 3 ) i.e. depth, is preferably no greater than the depth of the cavity  39  or the stops  37  whichever is less so the container front wall  15  is flush with the top edges of the jambs or the front wall is below the level of the edges of the jambs. The corner protector container  10  slips over the head jamb by inserting it into the jamb channel  23  and either the hinge jamb  32  or the striker jamb  33  by inserting it into the second jamb channel  24  and the container  22  sits inside the cavity  39  and the container front wall  15  is shown flush with the edges of the jambs. The open end formed by the top edges of  12 ,  13  and  14  end of the container portion  22  abuts against inside of the jamb to hold articles put into the container  22  for shipment with the prehung door and frame assembly  30 . The jamb panel  17  of the corner protector container  10  fits over either the head jamb  31  or the hinge jamb  32  and the second jamb panel  18  fits over the other jamb. The door side panel  20  folds down over and fits flash with the door  34  and ties into the jamb panel  17  and locks the corner protector  10  onto the prehung door and frame assembly (see  FIG. 1 a   ). 
         [0124]    Referring to  FIGS. 2, 8 and 13 , the corner protector container  10  can be formed from a unitary, planar, generally rectangular paperboard blank  11  and the container embodiment  100  from, blank  110  or  210 . in the FIGS. a dashed—line indicates fold lines and an x-x-x line represents a cut line (i.e. the paper board is cut along this line to permit folding of that portion of the blank  11 ). Fold lines are preferably scored such as by press scoring to reduce the paper stiffness along the fold line enabling an accurate fold of the paper board alone the designated fold lines. 
         [0125]    Referring to  FIG. 2 , blank  11  includes a container first side wall  12  connected by a fold line  12   a  to container back wall  13  which will face toward the door  34  when folded and placed. The container back wall  13  has locking key  13   a  extending from near the center of its lower edge along fold line  13   b.  The container back wall  13  is connected by a fold line  14   a  to container second side wall  14 . The container second side wall  14  is connected by a fold line  15   b  to a container front wall  15  which faces toward the outside of the cavity. Extending from the top of the container front wall  15  and connected by a fold line  15   c  is a tie  15   a  which has a cut line  15   d  running from, the top to the fold line  15   c.  The tie  15   a  preferably has a tapering or rounded top edge to facilitate ease in folding the blank into the corner protector container  10 . In the embodiment in  FIG. 2  extending from the bottom edge of the container front wall  15  and connected thereto by fold line  16   b  is a container bottom  16  which functions to close the bottom of the container  22 . Extending from the bottom edge of the container bottom  16  through fold line  16   c  is a bottom flap  21 . A key slot  16   a  is centrally formed along the fold line  16   c  for receiving the locking key  13   a  when forming the corner protector container  10 . The container bottom  16  has a width W 4  starting at fold line  15   b  no greater than the width W 2  of the container back wall  13  and less than the width W 5  of the container front wall  15 . The difference between W 2  and W 5  forms a jamb channel  23  when the corner protector container  50  is folded into shape. The container bottom  16  can be less than the width of the back wall  16  but should be wide enough to retain the articles placed in the container for shipment. The container bottom  16  has a length L 3  equal to the width W 1  of the container first side wall  12  which preferably has the same width or can. be less than W 3  as the container second side wall  14 . The bottom flap  21  has the same width W 4  as the container bottom  16  and a length no longer than the length of the container bottom  16 . Alternatively the container bottom  16  can be formed by extending the container bottom  16  from the first side  12  wall as shown in  FIG. 13  with the locking key being formed at the bottom of the second side wall. The reverse can also be employed i.e. extending the bottom  16  from the bottom of the second side wall  14  with the locking key being formed at the bottom of the first side wall  12 . Connected to container front wall  15  by fold line  17   b  is a jamb panel  17 . Defining the top edge of jamb panel  17  is fold line  17   c.  Formed along the lower edge of the fold line  17   c  is a centrally located key slot  17   a  for receiving key  19   a.  Connected to the upper part of jamb panel  17  through fold line  17   c  is a second jamb panel  18 . The width W 6  of the jamb panels  17  and  18  is about the same as width of the jambs making up the frame of the prehung door and frame assembly  30  to which the corner protector container  10  is attached. The fold lines  15   c,    17   c  and  20   c  lie in a straight line. The length L 2  of the jamb panel  17  and door side panel  20  and the fold line  17   b  is the same as the longest length of the container front wall  15 . The length L 2  is longer than the length L 1  by an amount at least as great as the thickness of the jambs of the frame of the prehung door and frame assembly  30 . When folded the additional length L 2  forms a second jamb channel  24  in the corner protector container  10  between the top of the first side wall  12 , back wall  13  and second side wall  14  when the container is folded into shape. In  FIG. 2  the bottom edges of  12 ,  13 ,  14 , fold line  16   b,    17 , and  20  are aligned in a straight line, however the bottom edges of  17  and  20  can be above or below the bottom edges of edges of  12 ,  13 ,  14  and fold line  16   b,  Connected to the top edge of the second jamb panel  18  is fold under flap  19  that has a width W 8  slightly narrower than the width W 6  of the second jamb panel  18 . The fold under flap  19  is connected to the second jamb panel  18  through two parallel fold lines  18   a  and  19   b.  Defined in the top edge of the fold under flap  19  is key  19   a  that mates with key slot  17   a  when the corner protector container  10  is folded into shape. The length L 4  of the jamb panel  18  can vary. The length L 5  of the fold under flap  19  is about the same as the length L 4  of the jamb panel  18 . In this embodiment the width W 8  of the fold down under flap  19  is slightly less than the width of the jamb panel  18 . This facilitates the insertion of the tie  15   a  and door side tie  20   a  into the envelope  25  formed when the fold under flap is folded into place under the jamb panel  18 . Connected to jamb panel  17  through fold line  20   b  is door side panel  20 . The width W 7  of the door side panel  20  can vary. Along the top edge of the door side pane  120  is fold line  20   c  that has connected to it door side tie  20   a.  Door side tie  20   a  has cut line  20   d  that permits the tie  20   a  to be folded down away from the door side panel  20  so that when folded perpendicular to jamb panel  17  the door side tie  20   a,  as is tie  15   a,  can be inserted into an envelope  25  formed when fold under flap  19  is folded under onto second jamb panel  18  and key  19   a  is inserted-into key slot  17   a.  This locks the door side panel into second jamb panel  18 . Friction between the parts secures the corner protector container  10  on to the corner of where the head jamb  31  connects to either the hinge jamb  32  or the strike jamb  33  of the frame of the prehung door and frame  30 . All parts  12 ,  13 ,  14 ,  15 ,  16 ,  17 ,  18 ,  19  and  20  are rectangular having square comers as defined by their edges and fold lines. Ties  15   a  and  2   a  axe preferably rectangular with tapered or rounded upper edges to facilitate insertion into the envelope  25  formed when fold under flap  19  is folded under second jamb panel  18 . The length of the outside edge of container first side wall  12 , fold line  12   a,    13 , fold line  14   a  and fold line  15   b  are all about the same L 1 . Fold line  17   b,    20   b  and the outside edge of door side panel  20  all have the same length L 2 , said L 2  is longer than L 1  so that when the container corner protector  10  is folded a jamb channel  23  is formed along the top edges of wall  13 ,  14  and fold line  15   c.  The embodiment in  FIG. 2  shows key slots and keys to secure the bottom and fold under flap. Other means of securing such as tape, adhesives, staples and the like can be used. 
         [0126]    The container  22  is formed by folding container first side wall  12  along fold line  12   a  perpendicular to container back wall  13 . Container back wall  13  is folded along fold line  14   a  perpendicular to container second side wall  14  so the front edge of container first side wall  12  touches the inside of the container front wall  15 . When so folded the face of first side wall  12  faces the inside wall of jamb panel  17  forming a second jamb channel  24 . Width W 1  and W 3  are preferably no greater than the depth of the cavity  39  (edge of jambs to the face of the door  34  or stops  37  whichever is less). 
         [0127]    To assemble the corner protector container  10  and attach it to the cavity  39  side of the prehung door and frame assembly  30  frame the fold under flap  19  is folded 180 degrees along  19   b  and  18   a,  onto second jamb panel  18  and secured by key  19   a  sliding into key slot  17   a.  This fold forms an envelope  25  into which ties  15   a  and  20   a  are later inserted to lock the corner protector container  10  onto the head jamb  31  and either the hinge jamb  32  or the striker jamb  33  of the prehung door and frame assembly  30 . 
         [0128]    The formed second jamb  18  &amp;  19  is then folded along fold line  17   c  until perpendicular to jamb panel  17 . Door side tie  20   a  is then folded along fold line  20   c  and tie  15   a  is folded along fold line  15   c  until perpendicular to jamb panel  17 . 
         [0129]    Door side panel  20  is then folded along fold line  20   b  until perpendicular to jamb panel  17 . Door side tie  20   a  is slid into the newly formed envelope  25  formed between second jamb panel  18  and fold under flap  19 . 
         [0130]    Container  22  is formed by folding container bottom  16  along fold line  16   b  until perpendicular to container front wall  15 . Bottom flap  21  is folded along fold line  16   c  until perpendicular to contain bottom  16  and container first side wall  12  is folded along fold line  12   a  until perpendicular to container back wall  13 . 
         [0131]    Locking key  13   a  is then folded perpendicular to container back wall  13 . Next the container back wall  13  is folded along fold line  14   a  until perpendicular to container second side wall  14  and container second side wall  14  is folded along fold line  15   b  until perpendicular to container front wall  15 . Locking key  13   a  is then inserted into key slot  16   a.  There is formed container  22  having an opening at the top of folded  12 ,  13  and  14 . The opening is where hardware or the like can be placed into the container  22 . The opening abuts against the inside of the jamb when the corner protector container  10  is secured at the corner of the frame. 
         [0132]    The final assembly is formed by placing desired contents into newly formed container  22  and then placing corner protector container  10  over the corner formed by the jambs of the prehung door and frame assembly  30  using the channels  23  and  24  formed by the folding process. The container front wall  15  is then folded along fold line  17   b  until perpendicular to jamb panel  17 , sliding tie  15   a  into the envelope  25  formed by  18  and  19  which locks the corner protector container  10  around the corner formed by the jambs of the prehung door and frame assembly  30 . 
         [0133]      FIG. 7  illustrates an intermediate stage of folding of corner protector container  10 . 
         [0134]    Referring to  FIGS. 8-13 , the container embodiment  100  is formed from a unitary, planar rectangular paperboard blank  110 , ( FIG. 8 ) or another embodiment of a blank  210  shown in  FIG. 13 . 
         [0135]    Blank  110  includes a container first side wall  111  connected by a fold line  111   a  to container back wall  112 . In the embodiment shown in FIG. S the container back wall  112  has first locking key  112   a  extending from near the center of its lower edge along fold line  112   c.  The container back wall  112  has a second locking key  112   b  extending from near the center of upper edge along fold line  112   d.  The container back wall  112  is connected by a fold line  113   a  to container second side wall  113 . The container second side wall  113  is connected by a fold line  114   a  to a container front wall  114 . Extending from the bottom of the container front wall  114  and connected by a fold line  114   c  is container bottom  115 . Extending from the bottom edge of container bottom  115  through fold line  115   b  is bottom flap  119 . A key slop  115   a  is centrally located along fold line  115   b  for receiving the locking key  12   a  when forming the container embodiment  100 . Extending from the top edge of the container front wall  114  and connected thereto by fold line  114   b  is a container top  116 . Extending from the top edge of the container top  116  through fold line  116   b  is a top flap  120 . A slot  116   a  is centrally formed along the fold line  116   b  for receiving the locking key  112   b  when forming the container embodiment  100 . The container bottom  115  has a width W 4  shown here as starting along fold line  114   a  about equal to the width W 2  of the container back wall  112  and less than the width W 5  of container front wall  114 . The container bottom  115  has a length L 3  and the container top  116  has a length L 4  equal to the width W 1  of the container first side wall  111  which has about the same width W 3  as the container second side wall  113 . The bottom flap  119  and the top flap  116  have about the same width W 4  as the container bottom  115  and the container top  116  (which is also about equal to W 4 ) and a length no longer than the length L 3  and L 4  of the container bottom  115  and container top  116 . Connected to container front wall  114  by fold line  117   a  is a jamb panel  117 . Connected to the jamb panel  117  through fold line  117   b  is door side panel  118 . The width W 6  of jamb panel  117  is about the same as width of the jambs making up the frame of the prehung door and frame assembly  30 . The length L 2  of the jamb panel  117  and door side panel  118  and the fold line  117   b  is preferably the same as, or as shown in  FIG. 8 , is greater than L 1 . The width W 5  is greater than width W 2 . When folded the additional length forms a jamb channel  123  between, the first side wall  111  and jamb panel  117  in the container embodiment  100 . The bottom edge of  111 ,  112 ,  113 , and fold lines  111   a,    113   a,    114   a,    114   b    114   c  and  117   a  are aligned in a straight line. The width W 7  of the door side panel  118  can vary. All parts  111 ,  112 ,  113 ,  114 ,  115 ,  116 ,  117 , and  118  are rectangular having square corners as defined by their edges and fold lines. Width W 7  of the door side panel  118  is preferably at least about the same as the thickness of the jamb members of the frame. The length of the outside edge of container first side wall  111 , fold line  111   a,  fold line  113   a,  fold line  114   a  and  117   a  are all the same, i.e. L 1 . Fold line  117   b  and the outside edge of door side panel  118  all about the same length L 2  and said L 2  is preferably longer than L 1 . Key locks  112   a  and  112   b  and key slots  115   a  and  116   a  are illustrated as the means for securing the container top  116  and container bottom, however, other means of securing can be employed such as for example, tape, adhesives, staples or the like. 
         [0136]    The container  121  is formed by folding container first side wall  111  along fold line  111   a  perpendicular to container back wall  112 . Container back wall  112  is folded along fold line  113   a  perpendicular to container second side wall  113  so the front edge of container first side wall  111  touches the inside of the container front wall  114 . When so folded the lace of first side wall  111  faces the inside wall of jamb panel  117  when folded along fold line  117   a  perpendicular to container front wall  114  forming a jamb channel  123 . Container bottom  115  is folded perpendicular to container front wall  114  along fold line  114   c  and bottom flab  119  is folded perpendicular to container bottom  115  along fold line  115   b  and key slot  115   a  is engaged with previously folded container back wall  112  and first locking key  112   a.  Container top  116  is folded perpendicular along fold line  114   b  to front wall  114  to face container bottom  115 . Top flap  120  is folded perpendicular to container top  116  and key slot  116   b  is engaged with second locking key  112   b.    
         [0137]    To assemble the container  121  and attach to the frame and into the cavity  39  side of the prehung door assembly  30  frame, the contents of the container are placed inside the container either before the container top  116  or the container bottom  115  are secured (or the container can be filled through the first side wall  111  before it is closed). The container is then placed into the cavity  39  with the container first wall  111  snug against the inside surface of one of the jambs. The jamb panel  117  is then folded perpendicular along fold line  117   a,  to form the jamb channel  123 , so that the inside surface of jamb panel fits flush with the outside surface of the frame jamb. Door side panel  118  is then folded along fold line  117   b  perpendicular to jamb panel  117  to fit flush with the door side edge of the jamb and secured in place with glue, staple, or banding. In one embodiment the container embodiment  100  is employed with a standard jamb corner protector  122  as shown in  FIGS. 11 and 12  such that the standard jamb corner protector holds the container embodiment  100  in place. 
         [0138]      FIGS. 9 and 10  illustrate the container embodiment  100  in various stages of folding before 
         [0139]    being attached to a jamb so the container  121  sits in the inside of cavity  39 . When attached the size of the container depth wise (W 1  and W 3 ) is preferably no greater than the depth of the cavity  39  so the container front wall  114  is essentially the same or less than the depth of the cavity. 
         [0140]      FIG. 13  illustrates another embodiment of a blank  210  for preparing a container  100 .
