Definitions

  • This invention relates to packaging, and especially to a package for 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 an easy-opening feature including a fold-down side 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.
  • Cut-sized paper such as conventional photocopy paper
  • Cut-sized 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.
  • 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.
  • 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.
  • ancillary securing devices such as straps and the like, rather than or in addition to adhesive, to hold such container lids onto their respective bases.
  • ancillary securing devices such as straps and the like, rather than or in addition to adhesive, to hold such container lids onto their respective bases.
  • such devices do not always prevent the lids from becoming disassociated from the bases.
  • the straps are loosened and are free to slip either partially or entirely off of the container, allowing the lids to become disassociated from the bases, resulting in product spillage and/or damage.
  • the free straps may likewise become entangled in the material handling equipment, resulting in machine shut downs and shipping inefficiencies. Operator safety is also reduced, as the free straps and free lids clutter the workspace.
  • 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. It is also desirable to provide a carton that the lid is directly attached the carton bases but yet strong enough to withstand the shear strain resulting from movement of the lid relative to the carton's base.
  • a combination of a smaller multi-ream container together with a carry handle, for example, is ideally suited for retail sales to home users.
  • 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.
  • 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.
  • 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.
  • the carton of the invention has a built-in carry handle and is adapted to hold more than one ream of paper, but may contain less than the five or ten reams normally placed in a conventional package.
  • one embodiment of 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. 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.
  • the base portion comprises a bottom wall, opposite end walls, and front and back walls folded from a single unitary blank of corrugated paper.
  • 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.
  • the lid portion comprises a lid folded from a single unitary blank.
  • the lid has a top wall, depending end flanges, and depending front and back flanges.
  • the back flange has glue flaps on its opposite ends, turned inwardly to lie inside and parallel to the end walls.
  • the lid back flange and associated first glue flaps are secured by adhesive or other suitable fastening means to the back 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.
  • Second glue 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.
  • the bottom edge of the lid front flange is secured to the base portion front wall by a spot of glue, adhesive or other suitable fastening means.
  • a tear strip may be used to securely hold the lid to the base portion.
  • a carry handle is attached to the base portion to facilitate carrying the carton, and comprises a flexible strap attached to a base plate that is secured to the inner surface of the front wall of the base portion.
  • the flexible strap extends through aligned openings in the base portion and the lid top wall.
  • inset plate to augment and reinforces the attachment of the carry handle to the carton.
  • the carry handle is directly attached to the front wall of the base portion without using an intermediate insert plate.
  • insert plates are described in U.S. application Serial No. 1 1/580515 filed on October 13, 2006 which is herein in its entirety incorporated by reference.
  • 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.
