     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to a paperboard container for shipping, storing and handling a plurality of items such as, for example, paper products. More particularly, the invention relates to a shipping and storage carton for cut sheets of paper, wherein the carton has a size and weight to promote easy handling and storage and has a tear-strip to facilitate access to the paper. The carton may be reclosed after opening to keep unused paper fresh and neatly stacked, and has a built-in handle for ease and convenience in carrying the carton. 
       BACKGROUND OF THE INVENTION 
       [0003]    Cut-sized paper, such as conventional photocopy paper, typically is wrapped in reams each containing, for example, 500 sheets. It is common for a plurality of reams to be bundled together and packaged in a corrugated container for shipping, storage and handling. For example, it is common to package from five to ten reams of paper in a single container, with a lid secured over the container to keep the reams from falling out of the container during shipping and handling. Since a single ream of paper weighs about five pounds, packages containing from five to ten reams of paper are heavy and difficult to handle. Moreover, they are relatively large and require substantial storage space. Further, the reams of paper are closely surrounded by the container walls, and the lack of space between the reams of paper and the container walls makes it difficult to remove the reams of paper for use. Additionally, each ream must be individually opened to gain access to the paper, and the ream wrap disposed of. 
         [0004]    Single wrapped reams of paper also are commonly sold, and although these packages are easy to handle and store, they do not protect the paper from physical damage. Further, most equipment used in the home or in small offices does not hold a full ream of paper. Consequently, after a ream is opened and the desired amount of paper removed, the remaining unused paper is unprotected. 
         [0005]    Many home and small office users prefer to purchase several reams of paper at once, rather than to buy single reams more frequently, but prefer not to buy as many as ten reams at once. Packages have been developed that hold five reams of paper, but even these packages are heavy, and, as such, are more suitable for industrial and commercial purchasers, which typically will have material handling equipment such as power lifts and hand carts to handle such heavy items. Average home users who wish to purchase several reams of paper at once typically do not have access to such material handling equipment. 
         [0006]    Unwrapped cut sheets of paper are sometimes packaged loose in cartons designed to closely fit the paper and protect it from damage. Unwrapped cut sheets of paper do not require removal and discarding of ream wrap, but conventional cartons of this type generally are also sized to hold from five to ten reams of paper and thus are relatively difficult to handle and store. Moreover, these cartons generally have either a removable lid or foldable flaps to close the top of the carton, and the lid is removed or the flaps opened to form an open top through which product is removed from the carton. With such packaging it is difficult to remove the contents without damaging the carton or inverting it to pour the contents out because of the lack of space to insert the hands of the user between the side walls of the carton and the paper stored therein. 
         [0007]    It is common practice to provide a tear strip in the corrugated container described hereinabove. In use, the tear-strip is gripped at one end thereof and pulled to tear it from a panel of a corrugated container. In many cases, removal of the tear-strip permits the corrugated container to hinge open. In others, more than one tear-strip may be used to provide for removal of a portion of a container. See U.S. Pat. Nos. 6,422,454; 3,863,834; 7,140,493; 5,487,506; 3,831,834; 3,712,531 &amp; U.S. Pub. No. 2005/0051573; 2004/0232039, 2003/0234284, 2003/0116613, 2002/0166889. In general, the tear-strip comprises a pair of perforation lines running lengthwise or across a panel. The tear-strip has a tab at one end which is gripped by a user and pulled in an upward and forward direction to remove the tear-strip from the panel. Generally, when a user opens a container or carton or box having a tear-strip, occasionally, the tear-strip breaks and results an unattractive carton which is a problem if the end user intends on re-using the carton or keeping it around. Often a tear starts on the outer layer of the paperboard, and will tear at an angle all the way across the container or carton. 
         [0008]    Therefore, it is desirable to provide a container or carton having a tear strip that overcome the aforementioned problem described hereinabove and to provide an aesthetically pleasing container or carton that removal of the tear-strip permits the corrugated container to hinge open. 
         [0009]    It is also desirable to provide a carton for shipping and storing sheets of paper, such as photocopy paper or the like, which not only is smaller and lighter in weight than conventional multi-ream containers and accordingly is easier to handle and store, but which also protects the paper against physical damage from the environment. 
         [0010]    It is also desirable to provide a carton that enables the sheets of paper to be easily and quickly unloaded from the carton, wherein the carton is adapted to remain sealed during shipping, handling and storing operations without the need to utilize ancillary securing devices such as straps and the like, and wherein the carton may be reclosed after opening. 
         [0011]    In addition, it is desirable to provide an apparatus, such as a carry handle or the like, associated with the carton to facilitate handling thereof. A combination of a smaller multi-ream container together with a carry handle, for example, is ideally suited for retail sales to home users. 
       SUMMARY OF THE INVENTION 
       [0012]    The present invention is directed to improve the tear-strip of a corrugated container when a user tears a corrugated container open using conventional tear-tape. Using a series of strategically placed cut lines along the tear-tape path, the user can effectively control the direction that the tearing travels, and therefore, prevent the breaks of the tear-strip. 
         [0013]    The main advantage of the inclined cut lines is to improve the visual characteristics of the container/carton/box after it is opened using a tear-tape or a tear-strip. The inclined cut lines feature control the direction of the stress tear, keeping it back towards the tear-strip instead of across the carton surface. The inclined cut lines feature allows the tear to proceed in a very predictable manner to give an attractive edge and not compromise the structural integrity of the container/carton/box. 
         [0014]    The present invention provides a container having a box-shaped main body portion and a lid that is sized and configured to fit over an open upper end of the main body. Sidewalls of the lid telescope over mating sidewalls of the main body and are adhered thereto, such as by adhesive or tape. One sidewall of the lid includes a tear-strip defined by two parallel inclined cut lines running along the length of the middle of the sidewall panel. One end of the tear-strip includes a tab for gripping by a user. Alternatively, a tear strip might be provided in additional sidewalls of the lid. 
         [0015]    The present invention is directed to a paperboard container comprises a plurality of the panels folded with one another. The container comprises at least one panel comprising a tear-strip which comprises a pulling tab at one end. The tear-strip comprises at least two substantially parallel rows of a plurality of inclined cut lines extending along the least one panel. Each of the inclined cut lines comprises an initial end and a terminal end. The terminal end of the cut line is in spatial relation with the initial end of the adjacent cut line whereby a tear initiated at the terminal end of the cut line terminates at the initial end of the adjacent cut line in the direction of tear. 
         [0016]    One aspect of the present invention is to provide a lidded container for shipping, storing and handling a plurality of items, such as, for example, prepackaged reams of paper and the like. 
         [0017]    Another aspect of the present invention is to provide a lidded container wherein the lid is secured to the open upper end of the container main body without the use of straps, films or the like. 
         [0018]    The present invention comprises a carton for shipping and storing cut sheets of paper, wherein the carton holds fewer sheets of paper than conventional containers for this purpose, and is therefore lightweight and easy to handle and store. The carton is constructed for easy access to the paper for unloading it from the carton, and is particularly adapted to ship and store unwrapped sheets of paper, although it may be adapted for shipping and storing individually wrapped reams of paper. 
         [0019]    The carton includes a base portion having at least one side wall that may be pivoted downwardly to open the carton and expose the contents for easy removal, and a lid portion engaged over the base portion to close the top of the carton and normally hold the pivoted side wall in closed position. When the lid is opened, that side wall may be pivoted downwardly to expose the paper at the top and one side to facilitate access to it. 
         [0020]    The openable side wall enables the user to easily and quickly grasp and unload the paper stored in the carton, without the necessity of forcing the hands or fingers between the carton side walls and the contents, or turning the carton over and dumping out the contents. Moreover, the lid and openable side wall may be reclosed to protect the paper remaining in the carton. 
         [0021]    In a preferred embodiment the carton of the invention has a built-in carry handle and is adapted to hold more than one ream of paper, but less than the five or ten reams normally placed in a conventional package. For example, the carton of the invention is adapted to hold approximately three reams of paper, resulting in a lightweight package that is easy to handle. It is not intended, however, to limit the invention to a carton for holding three reams of paper. The carton can be adapted for any quantity of paper, but is generally limited to an amount that is easy to handle and store and that the built-in carry handle can reliably support, which generally does not substantially exceed three reams. After the carton is opened, the user may simply grasp and unload as many sheets as desired, without the need to open individual reams, and the carton may be reclosed to protect the unused sheets. 
         [0022]    In a preferred construction, the base portion comprises a bottom wall, opposite end walls, and front and back walls folded from a single unitary blank of corrugated paperboard. End flaps on the back wall are folded inwardly and secured to the end walls by adhesive or other suitable fastening means so that the back wall and end walls remain in an upright position. End flaps or tuck-in flaps on the front wall are folded inwardly but are not attached to the end walls. Instead, they tuck in between the end walls and paper held in the carton, whereby the front wall can be pivoted downwardly to open the front of the carton. After the desired quantity of paper is removed from the carton, the front wall can be pivoted back up to an upright position, with the tuck-in flaps tucked between the end walls and paper to re-close the carton. 
         [0023]    The lid portion comprises a lid folded from a single unitary blank, with an insert sheet and carry handle assembled to it. The lid has a top wall, depending end flanges, and depending front and back flanges. The depending front flange comprising a tear strip being defined by two parallel successive rows of inclined cut lines. Each of the inclined cut lines having a length (K) and further being spaced apart by a distance (D). The ratio of D/K is from 1:2 to 4:1. The back flange has end flaps on its opposite ends, turned inwardly to lie inside and parallel to the end flanges but unattached to the end flanges. In the assembled carton, the lid back flange and associated end flaps are secured by adhesive or other suitable fastening means to the back wall and end walls, respectively, of the base portion. The lid front flange has a width to extend downwardly over an upper edge portion of the base portion front wall, to hold the front wall in its upright closed position when the lid is in its operative closed position. End flaps on opposite ends of the front flange are turned inwardly to lay inside and parallel to the end flanges and are attached to the end flanges by adhesive or other suitable fastening means. A glue strip on the bottom edge of the lid front flange is secured by adhesive or other suitable fastening means to the base portion front wall, and a tear strip extends along the bottom edge of the front flange between the front flange and the glue strip. With this construction, when the tear strip is removed the lid may be pivoted upwardly to expose the paper held in the carton and uncover the front wall so that it may be pivoted downwardly to facilitate access to the paper. 
         [0024]    A carry handle is attached to the lid to facilitate carrying the carton, and comprises a flexible strap attached to a base plate that is secured beneath an insert panel placed in the lid between the lid top wall and the top sheets of paper. The flexible strap extends through aligned openings in the insert panel and lid top wall. The insert panel may comprise corrugated cardboard, or chipboard, or other suitable material. 
         [0025]    The carton of the invention may be opened to gain access to the paper stacked inside, and reclosed to protect the remaining paper. It does not require substantial adhesive attachment between the lid and the base, or separate securing means such as straps to keep the lid assembled to the base. Further, the carton preferably holds more than one ream of paper, preferably about three reams, and because of its reduced size and weight, and the provision of a carry handle, the carton is easy to carry and store.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0039]    A preferred carton in accordance with the invention is indicated generally at  10  in the drawings. The carton comprises a rectangularly shaped base portion  11 , a lid portion  12 , and a carry handle  13 . The base portion has a bottom wall  14 , opposite end walls  15  and  16 , a back wall  17 , a movable front wall  18 , and an open top  19 . The lid  12  is telescopically received over the open top and has a top wall  20 , depending end flanges  21  and  22 , a depending back flange  23 , and a depending front flange  24 . A glue strip  25  is joined to the bottom edge of the front flange to secure the front of the lid to the base portion front wall. A tear strip  26  extends between the front flange and glue strip to separate the front flange from the glue strip and enable the lid to be pivoted upwardly. The construction and usage of the tear strip  26  will be described in greater detail hereinafter. 
         [0040]    Details of construction of the base portion  11  can be seen best with reference to  FIGS. 1 and 6 . A blank B 1  for making the base portion  11  is illustrated in  FIG. 1 , and comprises bottom wall panel  14 , opposite end wall panels  15  and  16  foldably joined to opposite ends of the bottom wall panel, back wall panel  17  foldably joined to a back edge of the bottom wall panel, and movable front wall panel  18  foldably joined to a front edge of the bottom wall panel. Glue flaps  27  and  28  are foldably joined to opposite ends of the back wall panel, and tuck-in flaps  29  and  30  are foldably joined to opposite ends of the front wall panel. 
         [0041]    Assembly of the base portion  11  is seen best in  FIG. 6 . The glue flaps  27  and  28  on opposite ends of the back wall  17  are folded inwardly and glued or otherwise suitably fastened to the inner surface of the respective end walls  15  and  16 , but the tuck-in flaps  29  and  30  on opposite ends of the front wall  18  are merely folded inwardly to lie against the inner surface of the end walls. The tuck-in flaps slide along the end walls, between the end walls and paper held in the carton, when the front wall  18  is moved between its upright and lowered pivoted positions. The tuck-in flaps may be suitably shaped, e.g., with a curvilinear free end edge  31  as shown, to facilitate entry of them into the space between the end walls and paper as the front wall is moved to its upright closed position. A finger access cut-out  32  may be provided in the upper edge of the front wall  18  to facilitate moving it downwardly, if desired. 
         [0042]    Details of construction of the lid portion  12  can be seen best with reference to  FIGS. 2-5 . A blank B 2  for making the lid  12  is illustrated in  FIG. 2 , and comprises top wall panel  20 , end flange panels  21  and  22  foldably joined to opposite ends of the top wall panel, back flange panel  23  foldably joined along fold line L to a back edge of the top wall panel, and front flange panel  24  foldably joined along a front edge of the top wall panel. Glue strip panel  25  is joined to the free edge of the front flange panel by tear strip  26  extending between the front flange and glue strip to enable separation of the front flange from the glue strip. First glue flaps  33  and  34  are foldably joined to opposite ends of the front flange panel  24 , and second glue flaps  35  and  36  are foldably joined to opposite ends of the back flange panel  23 . A shaped opening  37  is formed generally through the center of the top wall panel to receive the carry handle  13  as described below. 
         [0043]    As seen best in  FIG. 4 , the first glue flaps  33  and  34  on opposite ends of the front flange panel  24  are secured by adhesive or other suitable fastening means against the inner surface of the respective end flanges  21  and  22 , but the second glue flaps  35  and  36  are merely folded inwardly parallel to the end flanges and are not attached thereto. A band of adhesive  38  is applied along a bottom edge of the back flange panel  23  and a bottom edge of the second glue flaps  35  and  36  to attach these parts to the back wall and end walls, respectively, of the base portion when the lid is assembled to the base. The glue strip  25  also is adhesively attached to the base front wall, and with the band of adhesive  38  comprises the only adhesive attachment of the lid to the base portion. This permits the lid to be pivoted upwardly about the fold line L when the tear strip is removed to separate the front flange of the lid from the glue strip (see  FIG. 8 ). That is, the end flanges  21  and  22 , being free of attachment to the second glue flaps  35  and  36 , are permitted to slide along the glue flaps and not resist upward movement of the lid as it is raised to its upward pivoted position. 
         [0044]    Referring to  FIGS. 7A &amp; 7B  and  11 , the front flange panel  24  includes two successive rows of inclined cut lines  56  running lengthwise generally parallel to fold line L. The two successive rows of inclined cut lines  56  are parallel to one another and are spaced apart by a distance (C) as depicted in  FIG. 11 . The distance (C) can be varied from 0.25″ to 1.5″ depending on the configuration of the inclined cut lines  56 , but in the preferred embodiment of the present invention, the distance (C) is 0.75″. The inclined cut lines  24  are spaced from one another at a distance (D). Each of the inclined cut lines  56  includes a length (K) that is position at a perforation angle (α) with respect to the centerline  64 . Depending on the length (K) and the distance (D), the angle (α) varies accordingly. The angle (α) may be 30 0 , 35 0 , 40 0 , and 50 0  degrees, but in the preferred embodiment of the present invention, the angle (α) is 45 0  degrees as will be described hereinafter in greater detail. In the present invention, it was discovered by the inventor that for optimum tear, the length (K) should be twice longer than the distance (D) (i.e., D  2 K) so that the tear strip  26  is separated from the container  10  without molesting the front flange panel  24 . In other words, the preferred D/K ratio is 2:1. However, the D/K ratio may vary with the angle (α) and ranges from 1:2 to 4:1. The D/K ratio may vary with the angle (α) and ranges from 1:1 to 3:1. The D/K ratio may vary with the angle (α) and ranges from 2:1 to 3:1. The D/K ratio may vary with the angle (α) and ranges from 1:1 to 2:1. Referring specifically to  FIG. 11 , it should be noted that if perforation angle (α) is positive, then the tear direction should be from left to right. Conversely, if the perforation angle (α) is negative, then the tear direction should be from right to left. Inclined cut lines  56  are of any conventional form and preferably cut through the front flange panel  24  completely, although one or more of the inclined cut lines  56  may not extend through the entire thickness of the front flange panel  24 , but may instead only cut partially therethrough. Although not shown, the inclined cut lines  56  can be extended to encircle the container  10  to permit complete removal of the severed portion of the container  10 , if desired. The inclined cut lines  56  cooperate with one another to define the tear strip  26  where one end of the tear-strip  26  includes a pull-tab  58  for the purpose of gripping, as will be described in greater detail below. The tear-strip  26  is positioned near a centerline of the front flange panel  24 . 
         [0045]    Particularly referring to  FIG. 7B  in which illustrates the tear-strip  26  in accordance to a preferred embodiment of the present invention. The tear-strip  26  is defined at each of its side edges  58  by the plurality of inclined cut lines  56 . The direction of tear is indicated by an arrow. The tear-strip  26  has a tab  22  at one end which is gripped by a user and pulled in an upward and forward direction, as indicated by an arrow, to remove the tear-strip  26  from the front flange panel  24 . The tear strip  26  comprises at least two substantially parallel rows of inclined cut lines  56  extending along the front flange panel  24 . Each of the inclined cut lines  56  comprises an initial end  60  and a terminal end  62  in which the terminal end  62  of a cut line  56  is in spatial relation with the initial end  60  of the adjacent cut line  56  whereby a tear initiated at the terminal end  62  of the cut line  56  terminates at the initial end  60  of the adjacent cut line  56  in the direction of tear as shown by the arrow. 
         [0046]    While we do not wish to be bound by any theory, it is believed that the angle of the inclined cut line  56  with respect of the center line  64  has an effect on the extend to which a tear initiated at the terminal end  62  of the cut line  56  terminates at the initial end  60  of the adjacent cut line  56  in the direction of tear and thus the extend to which front flange panel  24  is torn or damaged. Therefore, the angle of the inclined cut line  56  with respect to the center line can vary widely provided the desired results are produced. In the preferred embodiment of the present invention, the angle of the inclined cut lines is 45 0  degrees with respect to the center line  64 . The inclined cut line having an angle 45 0  degrees results in tear-strip moving in the direction of the tear without tearing or damaging the front flange panel  24  as compared to embodiments in which the inclined cut lines  56  angle is greater than or less than 45 0  degrees. However, depending on the design of the tear-strip, other angles such as 25 0 , 30 0 , 35 0 , 40 0 , and 50 0  degrees are also within the scope of the present invention. In general, it will be appreciated that the practice of this invention is not limited to 45 0  degree angle, and, depending on the needs of a user, the inclined cut lines  56  can be any number of degrees as the design of the tear strip  26  permits. 
         [0047]    In use, as the tear-strip  26  is pulled from the front flange panel  24 , the cut portions readily separate. When the tear-strip  26  is pulled, pulling force is applied to the portion of the front flange panel  24  beyond the respective initial and terminal ends  60 ,  62  of each cut line  56 , and the tear-strip  26  is detached. In this connection, the terminal end portion of each cut line  56  slopes towards the next following cut line  56  so that tear is initiated in a direction towards the next following cut line  56 . At the same time, it will be noted that the initial end  60  of the next following cut line to the one where tear is being initiated has been reached by the tear-strip  26  in the direction of tear so that no tear force is required at the next following cut line  56  as the tear-strip  26  is pulled and substantially all the force of the pull is applied to the tear initiation at the terminal end  62  of the cut line. The tear proceeds and is completed along an edge substantially like the edge  58  under normal conditions of tearing as the paperboard shears from back to front and the tear-strip  26 . 
         [0048]    After the tear strip  26  had been removed from the front flange panel  24 , lid  12  may be pivoted about opposing sidewall panel  22  of the container  10 , thereby exposing the open upper end of the main body portion  14  so that items may be removed therefrom. Lid  12  may be positioned back over the open upper end of the main body portion  11 , thereby reclosing the container  10  for safekeeping of unused items as depicted in  FIG. 10 . Optionally, if a tear strip has been provided in both sidewall panels of the container  10 , the lid  12  may be removed entirely from the main body portion  11 , as will be obvious to those of ordinary skill in the art, upon reading the within disclosure. 
         [0049]    As seen best in  FIG. 5 , the carry handle  13  includes a flexible strap  40  attached to a rectangular base plate  41  that is adhesively attached to the bottom of an insert sheet  42  sized to fit in the lid beneath the top wall, with the strap projecting through a shaped opening  43  in the sheet  42  and through the shaped opening  37  in the lid top wall. The sheet  42  may be adhesively attached to the underside of the lid top wall, or merely fit into the lid between the top wall and the paper sheets without being attached to the top wall. Either way, this construction results in a very strong carry handle. 
         [0050]    As seen in  FIGS. 7-10 , the package is compact, enabling it to be easily stored under a desk or on a shelf. Opening of the package is easily accomplished simply by removing the tear strip and pivoting the lid upwardly, after which the front wall can be pivoted downwardly to gain access to the paper held in the carton. After the desired amount of paper has been removed, the front wall can be returned to its upright position, with the tuck-in flaps inserted between the base end walls and the paper held in the carton, and the lid returned to its lowered position to close the package and hold the front wall in its closed position. 
         [0051]    While the invention has been shown for holding unwrapped sheets of paper, it should be understood that it could be used for holding wrapped reams of paper, and although the preferred embodiment is designed for holding about three reams of paper, the carton could be sized for holding other quantities of paper so long as the size and weight do not exceed amounts (for example, about 20 pounds) that provide ease of handling and carrying by the carry handle. 
         [0052]    While particular embodiments of the invention have been illustrated and described in detail herein, it should be understood that various changes and modifications may be made to the invention without departing from the spirit and intent of the invention as defined by the scope of the appended claims.
