CLAIM OF PRIORITY 
     The present application claims priority to U.S. Provisional Application No. 62/488,023 filed on Apr. 20, 2017, the content of which is hereby incorporated by reference into this application. 
    
    
     BACKGROUND 
     Field of the Disclosed Subject Matter 
     The disclosed subject matter relates to a container for storing and dispensing a film or sheet material packaged on a roll, such as plastic film wrap or other such products. 
     DESCRIPTION OF RELATED ART 
     Various film or sheet type products are available in roll form, such as products used to cover or wrap items. For example, plastic film wrap is often used to adhere to and cover a perishable item, or to the sides of an open container containing the perishable item. The properties of the plastic film wrap can be provided with performance properties, such as elasticity and adhesion characteristics, to provide an air tight seal about the perishable item or opening of the container. 
     A variety of dispensing containers are known to hold rolls of film or sheet material, such as plastic film wrap, wax paper, parchment paper, aluminum foil, and the like. Such dispensing containers can be provided with a sharp and/or serrated edge to allow a user to cut the material with the edge. However, conventional dispensing containers generally are not configured to secure a film roll therein. Furthermore, properties of certain films, such as plastic wrap, can cause undesirable effects, such as stretching or clumping of the plastic wrap before used for its intended purpose. 
     It is therefore desirable to provide a dispensing container for a roll of film or sheet material that securely contains the roll therein and allows for easy dispensing and cutting of the film or sheet material. 
     Additionally, it is desirable to provide a single folded blank for forming such a dispensing container, which can reduce manufacturing complexity, as well as the number of components and costs associated with manufacture of the dispensing container.

The slider  111  can be configured to slide along the length of the track  109 . 
     A variety of cutter assemblies are known and can be used with the dispensing container of the disclosed subject matter. For the purpose of description and not limitation, suitable cutter assemblies are described in U.S. Pat. Nos. 7,918,151 and 7,921,756, each of which is incorporated by reference herein in its entirety. Additionally or alternatively, as shown in exemplary  FIGS. 11-16 , for purpose of illustration and not limitation, the cutter  107  can include a channel-shaped track  109  with a slider  111  disposed slidingly thereon. The slider  111  can have an upper slider portion  142 , a lower slider portion  146 , and an intermediate slider portion  144 , disposed between the lower slider portion  146  and the upper slider portion  142 . 
     A blade  140  can be disposed proximate the intermediate slider portion between the upper slider portion  142  and the lower slider portion  146 . The blade  140  can be disposed on one or both opposing sides of the intermediate slider portion  144 . The blade  140  can extend from the intermediate slider portion  144  outwardly towards a blade edge. The blade edge can define an angle θ 3  within a range of 10° to 90°, and as embodied herein can be about 45°, relative to the lower slider portion. 
     The upper slider portion  142  can include a top surface contoured to provide a finger engaging surface, such as a concave recess in the body of the upper slide portion  142 , which can provide a user with an improved grip to engage the slider. The upper slider portion  142  can include a textured or ridged surface to further improve the grip. The lower slider portion generally includes a body portion or flange dimensioned to fit within the track as further described below. 
     The track  109  can include bottom, opposing sidewalls extending upwardly from the bottom, and opposing track flanges  154  directed inwardly from the top portion of the opposing sidewalls to define the channel-shaped track. The track flanges  154  each extend from the opposing sidewalls to an inward free end. The track flanges  154  thus form a track gap  152  between the opposing inward free ends. The track flanges  154 , opposing sidewalls, and bottom can form a track cavity  158  therein. The intermediate slider portion  144  and blade portion  140  can extend from within the track cavity  158  through the track gap  152  to the upper slider portion  142  disposed above the track. 
     The lower slider portion  146  is sized to be disposed within the track cavity  158 , and to be configured to slide along the inner surfaces of the track bottom, opposing sidewalls, and opposing track flanges  154 . As embodied herein, the lower slider portion  146  can form the shape of a rectangular box, having a length dimension along the length of the track, and the width dimension across the track. The length dimension can be greater than the width dimension, thereby improving stability of tortious forces on the slider. For purpose of illustration and not limitation, a lubricious coating can be provided on the lower slider portion and/or inner surface of the track to enhance sliding movement. 
     Further in accordance with the disclosed subject matter, the track can include detents  113  or the like on opposing ends of the track  109 . The detents  113  resist or inhibit movement of the slider  111  along the track  109 . As illustrated by way of example, and not limitation, in  FIG. 16  the detents  113  can include small protrusions located on the bottom of the track. The protrusions can be sized to resist movement of the slider  111  along the track  109  through effective frictional retention of the slider  111 , while still allowing the slider to move over the detents  113  with the application of additional force. As shown in  FIG. 6 , the detents can be located at opposing ends of the track at a distance L track  apart. The distance between the detents L track  can be greater than the width of the product on the roll W roll  to ensure the slider is out of the way for a new cut. The detents  113  can be configured as spherically-shaped bumps protruding from the bottom of the track  111 . Additionally, or alternatively, the detents  113  can be configured having any suitable shapes, including but not limited to squares, rectangles, or triangles. Additionally, or alternatively, the track  109  can include pairs of detents spaced to engage opposing sides of the slider disposed thereon. 
     The track  111  can further include end stops  148  at opposing track ends  150 . The end stops  148  can be disposed on the bottom of the track and can be configured having any suitable shape, for example and as embodied herein, a wedge shape having a flat end facing the inward direction of the track and protruding from the track bottom. The flat end can extend from the bottom of the track to a height h of about one third, or more, toward the opposing top track flanges  154 . The flat end thus can be configured to inhibit or prevent the lower slider portion  146  from extending beyond the end stop  148 . The end stop  148  can be configured to allow the lower slider portion  146  to move beyond the sloped end of the wedge shape, for example during assembly of the cutter  107 . The end stop  148  can be disposed proximate the track ends  150 , with the detents  113  spaced a distance from the end stops  148  to accommodate the length of the lower slider portion  146  therebetween. The slider can be disposed between the detents  113  and the end stops  148 , for example to secure the slider when not in use. 
     The track flange  154  can include a flange coating  156  applied to its upper surface. The flange coating can include a material with soft and flexible properties to releasably adhere to a product being cut thereon to inhibit or prevent movement of the product during cutting. 
     The cutter  107  disclosed herein thus allows for cutting of the roll into sheets with improved accuracy and less effort. In this manner, for purpose of illustration and not limitation, an elastic product, such as plastic film wrap, can be cut without stretching or clumping the product. 
     As shown in exemplary  FIGS. 1-8 , for the purpose of illustration and not limitation, the roll  115  of material can be a roll of any suitable film or sheet material, including but not limited to paper, aluminum, tape, plastic, and fabric. The container  100  disclosed herein is particularly suitable and beneficial for use with a film or sheet material to be dispensed into thin sheets, such as plastic film wrap, wax paper, parchment paper, aluminum foil, and the like. As shown in  FIG. 6 , the roll can include inner roll  162  for holding the film or sheet material of the roll. The inner roll  162  can extend to and mate with the opposing sides of the container to increase stability of the roll during dispensing, and to ensure a maximum amount of the end lock  160  protrudes into the inner roll. The outer roll  164  can include the film or sheet material therein and can have a width W roll , as shown in  FIG. 6 . The front angle panel  106  can further include an adhesive strip  105  disposed thereon to secure the free end of the rolled material while operating the cutter and between uses. 
     When opening and closing the container  100 , for purpose of illustration and not limitation, the lid portion  104  can be hindgedly moveable relative to the base portion  102  between an open position and a closed position about the back panel upper edge  154 . When the container  100  is in the closed position, the lid portion can be disposed over the compartment  103  of the base portion. In the closed position, the lid portion  104  protects the roll  115  and the cutter  107  allowing for safe transportation and storage of the container  100 . The location of the cutter  107  on the front angle panel  106  makes use of the space within the container compartment between the rounded roll and the rectangular container. As such, the cutter  107  can be fully assembled on the front angle panel  106  in an end useable form, while fully protected by the lid. This allows for delivery of the container  100  to a user fully assembled, thus avoiding the need for any self-assembly. Further, the lid portion  104  allows for efficient stacking of the container  103  for easy storage and/or display on a retail shelf. The lid portion  104  can be secured in the closed position, such as by a frangible sticker  119 , as described in additional detail below. 
     To move the lid portion  104  from the closed position to the open position, a user can engage and rotate the lid portion  104  about the back panel upper edge  154 . The lid portion  104  can rotate 270° about the back panel upper edge  154 , with exemplary use between 90° and 180° from the closed position, to allow for full access to the roll  115  and cutter  107 , and easy operation of the container  100 . After use, to move the lid portion  104  from the open position to the closed portion, a user can engage and rotate the lid portion  104  about the back panel upper edge  154  over the base portion compartment  103 , and back into the closed position. 
     In operation of dispensing film or sheet material from the container  100 , as shown in exemplary  FIGS. 9 and 10 , when the container  100  is in the open position, a user can engage the film or sheet material, such as plastic film wrap, contained on the roll  115 , and dispense a desired amount up and over the front angle free end  146  and cutter  107 . During dispensing of product from the roll  115 , the front angle panel  106  can keep the roll  115  secured within the container  100 . The dispensing of the roll  115  creates a substantially upward and angled force of the roll  115  that is counteracted by the front angle panel  106  located substantially above the roll  115 , which can engage the roll during dispensing and retain the roll with the compartment. The front angle panel can include an intermediate portion that is joined at either end to the opposing sides of the base portion, thus enhancing the structural strength of the front angle panel  106 . The intermediate portion can be between the cutter  107  and the free end  158 . The angle and position of the front angle panel  106  allows a user to access the roll  115  and engage a free end of the wrap to initiate the dispensing process. The cut outs  117  further increase the accessibility of the roll, for example, in between cuts. Additionally, the angle, position, and flexibility of the front angle panel  106  allows the entire roll  115  to be completely removed or inserted from the container  103  by a user, if so desired. Additionally, the end locks  160  can also counteract the substantially upward and angled force of the roll  115  by engaging the inside surface of the inner roll  162 . Alternatively, the front angle panel can be shortened, such as to the cut outs  117  as shown in  FIG. 1  to an alternative front angle edge  188 , to allow increased access to the roll. With a shortened front angle panel  106 , the end locks  160  can counteract the substantially angled and upward force of the roll  115 . 
     As shown in exemplary  FIG. 10 , to remove the desired amount of product, the user can lay the product along the front angle panel  106  and cutter track  109  and slide the slider piece  111  along the length of the track  109  to engage and cut through the product. Once a desired product sheet is removed from the roll  115 , the sheet can be used for any desired purpose, such as covering an item. As the product sheet is being cut, the user can slide the slider  111  past the detents  113  to secure the slider  111  on the side of the track  109  for a future use (as further explained below). Optionally, the user can secure the remaining product between the cutter  107  and the roll  115  onto the adhesive strip  105  for a future use. The adhesive strip  105  can be configured retain the product within compartment  103  during storage and transportation of the container  100 . Additionally or alternatively, adhesive can be disposed directly onto the slider track and can be similarly configured to retain the product within compartment  103 . The use of the adhesive, whether disposed on a panel or on the track, allows the user to remove the end of the product without needing to re-engage the roll  115 . 
     As shown in exemplary  FIG. 17  for illustration and not for the purpose of limitation, the cut outs  117  on the front angle panel can facilitate easy access to the roll, such as access to the end of the roll  115  of product as embodied herein. The cut outs  117  can be located on either or both ends of the front angle panel  106 . Alternatively, there can be a single cut out located along the length of the front angle panel  106 . As shown in exemplary  FIGS. 1 and 17 , the cut outs  117  can be substantially rectangular in shape. Alternatively, the cut outs can have a rounded shape, square shape, or any other shape. The inner corner of the cut outs  117  can be rounded, as shown in  FIG. 17 , or can include a sharp angle. The outer corner of the cut out can be a sharp angle, as shown in  FIG. 17 , or can include a rounded edge. 
     As shown in exemplary  FIG. 18 , the container can additionally include a frangible sticker  119  disposed between the front lid panel  116  and front base panel  108 . The frangible sticker  119  can be configured to keep the container  100  secure in the closed position by operatively connecting the front base panel  108  to the front lid panel  116 . The frangible sticker can be formed integrally with and as part of the lid portion, or as a separate piece as embodied herein for illustration and not for limitation. That is, the frangible sticker  119  can include an upper panel  123 , a strip panel  125 , and a lower panel  127 . For purposes of illustration and not limitation, the frangible sticker  119  can include two rows of perforated strips along its length and a tab with an arrow located thereon. Additionally or alternatively, the frangible sticker  119  can include two tabs, one located on each end of the frangible sticker. The perforated strips can be configured to separate the strip panel  125  from the upper panel  123  and lower panel  127 . The upper panel  123  can be secured to the front lid panel with adhesive, or any other securing means. Similarly, the bottom panel  127  can be secured to the front base panel  108  with adhesive, or any other securing means. In operation, a user can engage the arrowed tab and pull the strip portion away from the upper portion and lower portion at the perforated strips. Once the strip is removed, the frangible sticker no longer operatively connects the front angle panel to the front lid panel and the lid portion is free to move to the open position. Additionally or alternatively, the strip panel  125  can include a reinforcing material. For example, the reinforcing material can substantially cover the area of the strip panel  125 . The reinforcing material can include a sturdier material than the frangible sticker such that the reinforcing material ensures the strip panel  125  remains intact during operation. For purpose of illustration and not limitation, the frangible sticker can be manufactured from a thin sheet of polyethylene terephthalate and the reinforcing material can be manufactured from paper with a weight of at least around 105 grams per square inch. 
     Alternatively, the front lid panel  116  can be extended beyond the lid free end  158  to form the frangible sticker. The front lid panel  116  can extend to the front base panel  108 , when the container is in the closed position. The front lid panel can include a perforated strip along its length, and a tab on the strip. The front lid panel can be adhered to the front angle panel with adhesive to secure the container in the closed position. To open the container  100 , a user can engage the tab and disengage the strip portion at the perforations.

     Still referring to the blank  300  of  FIG. 29 , the blank  300  can additionally include slots  350 ,  351  located on each back side tab  330 ,  332 . Each slot can be a narrow, horizontal cut out rounded at each end. The slots can be sized to fit the end lock free end  316 ,  326  therein when the blank  300  is formed into the container  100 . 
     Referring again to  FIG. 29 , the front angle panel  306  can extend from the front angle base panel  308  to a front angle edge  346 . The front angle edge  346  can extend horizontally between opposing end lock tabs  310  and  320 . The front angle panel  306  can include no cut outs or can include substantially smaller cut outs as compared to the cut outs embodied in blank  200 . Thus, when formed into the container  100 , the front angle edge  346  can be secured on opposing ends of the container to allow for easy assembly of the end lock tabs  310  and  320 . Securing the front angle edge  364  in this manner can also enhance the structural strength of the front angle panel  306 , which keeps the panel at a consistent angle throughout repeated use. See for example, front angle edge  188 , as shown in  FIG. 1 . The length of the front angle panel, defined from the front base panel  308  to the front angle edge  346 , can be shorter than the corresponding length on the blank  200  of the front angle panel  206 . This decreased length can increase accessibility to the roll in the container formed from the blank. The length can be decreased because the container  100  formed from the blank  300  can secure the roll with the end lock tabs  310 ,  320 , as an alternative of, or in addition to, securing the roll with only the front angle panel  306 . 
     The blank  300  can be manufactured and erected in a similar manner as described above regarding the blank  200 . As shown in  FIG. 30 , for purpose of illustration and not limitation, once the container is erected using any method, such as the methods previously described herein, the sides of the container  100  can be formed from the blank  300  by folding the end lock top slip  314 ,  324  onto the end lock bottom slip  315 ,  325  about the end lock free end  316 ,  326 . The end lock free end  316 ,  326  can be inserted into the slot  351 ,  352  on the back side tabs  330 ,  332 . Finally, the bottom side panel  360 ,  362  can fold onto the end lock tabs  310 ,  320  to secure the end lock upper portion  314 ,  324  and end lock lower portion  312 ,  322  against the back side tab  330 ,  332  using adhesive, or any other securing means. The embodied manufacturing method thus reduces the need for adhesive. 
     The container  100  and blank  200 ,  300  disclosed herein are preferably disposable, but the containers can be recycled or reused as desired. Additionally, the materials from which the container is made need not be the same throughout. The container and blank described herein can be manufactured from any suitable material, including but not limited to cardstock, pulp board, paperboard, micro-flute corrugated material, expanded polystyrene foam, oriented polystyrene (OPS), polypropylene, mineral filled polypropylene, amorphous polyethylene terephthalate (APET), thermoplastics, paper, recycled board, virgin board, or any other suitable material. As embodied herein, the container and blank can be manufactured from cardstock with about 18 to 22 points thickness or cardstock with a weight of about 350-450 grams per square meter. The blank of the disclosed subject matter can be retained in the assembled configuration, for example and without limitation, by adhesive bonding. Additionally or alternatively, the blank can be retained in the assembled configuration by tucking projecting portions of blank into slits provided and configured to clasp or otherwise engage such projecting portions. Additionally or alternatively, the container can be formed without the use of a blank, such as with an injection molded container. Other suitable additional or alternative retention means are within the scope of the disclosed subject matter.
