Description

"Dispenser Carton"

This invention relates to a packaging arrangement for sheet paper, which provides a combination of storage- transport carton and a dispenser for use by an end user.

For many uses, such as photocopiers and laser printers, paper is supplied in a convenient sheet size, typically DIN A4, to end users who require relatively small quantities of paper. Conventionally, the paper is wrapped in reams of 500 sheets and packed five reams to a carton. It is also conventional to hold the carton shut with plastic strapping.

This arrangement has a number of disadvantages. The weight of a full carton is rather more than is recommended by health and safety authorities for carrying in one hand. However, users do typically carry a carton in one hand by means of the plastic strapping, which is not intended for this purpose and may injure the hand. Also, for many office machines only a relatively few sheets of paper are required at a time. Once a ream has been removed from the carton and its wrapping opened, it is virtually impossible to reclose the wrapping and reinsert the ream in the carton. Opened reams are therefore left lying about and are likely to suffer from accidental damage. This is particularly acute where a selection of weights and colours of paper is required, as in desktop publishing.

An object of the present invention is to provide an improved arrangement for handling and storing sheet paper.

Accordingly, the present invention provides a packaging arrangement for sheet paper, comprising a carton holding at least one stack of sheet paper, the carton being openable in such a manner that selected numbers of sheets can be removed from and replaced in the stack.

In a particularly preferred form of the invention, the carton contains a plurality of trays each holding a stack of sheet paper, the trays being removably housed in the carton, and in which the trays on removal from the carton are useable without further manipulation as dispensers of paper sheets.

Preferably, the carton is provided with a carrying handle. In a preferred form of the invention, the carton contains a plurality of trays, one above the other, and the carrying handle is on the top of the carton.

Preferably, the carton is provided with a tear strip or other means allowing a portion of the carton to be removed leaving at least one tray exposed for removal from the carton. The tear strip may be operable to remove a top portion, leaving the upper tray exposed for removal by lifting upwardly. Alternatively, the tear strip may be operable to remove a front portion, leaving the trays exposed for removal by sliding forwardly.

The carton is preferably formed by folding and gluing a one-piece blank of a material which includes a moisture barrier, such as a polythene laminate.

Preferably also, each tray is an open-topped tray defined by a base, side walls, a rear wall, and a front wall, the front wall being cut away to form paper- retaining edge portions. One of the edge portions may suitably be marked with a scale or other indicia for measuring quantities of sheets within the tray.

It is particularly preferred that the carton contains, in the case of paper of 80-100g/m² substance, about 2,000 sheets split equally between two trays.

Embodiments of the present invention will now be described, by way of example only, with reference to the drawings, in which:

Fig. 1 is a perspective view of a dispenser carton forming one embodiment of the invention; Fig. 2 is a perspective view of the dispenser carton of Fig. 1 after opening; Fig. 3 is a perspective view of a dispenser tray removed from the carton; Fig. 4 illustrates a blank suitable for forming the carton of Fig. 1; Fig. 5 is a perspective view showing the underside of the carton; Fig. 6 illustrates a blank suitable for forming the tray of Fig. 3; Fig. 7 is a perspective view of a partially erected carton used in a second embodiment of the invention; Fig. 8 shows the carton of Fig. 7 erected and filled; Fig. 9 shows the carton opened for use; and Fig. 10 shows the same carton, but with different contents, opened for use.

Referring to Fig. 1, a carton 10 is formed of any suitable material such as conventional carton board having twin walls spaced apart by a corrugated inner member. The carton 10 is formed by folding up and gluing a one-piece blank as is well known per se. Preferably, the carton board is laminated with a polythene film or the like (not shown) and is glued up with continuous glue seams, whereby the contents are substantially protected against picking up moisture. The carton 10 is provided with a top carrying handle 12 which is suitably a moulded plastics strip having enlarged ends seating behind slots 14 in the top of the carton 10. Such handles are known in the packaging art in cartons for other uses.

The carton 10 is also provided with a tear strip which can be operated by ends defined by slits 16 in one side of the carton to separate and remove the top of the carton, to achieve the condition shown in Fig. 2.

The carton 10 as supplied to the end user contains approximately 2,000 sheets of A4 paper contained in two removable trays 18. Each of the trays 18 is formed by folding up a blank of board, conveniently of the same material as the carton 10. The trays 18 may be removed and the carton 10 disposed of, the trays then being used as dispensers.

As seen in Fig. 3, each tray 18 has a base 20, side walls 22 and 24, a rear wall 26 and a front wall 28, the top being open. The front wall 28 is cut away as indicated at 30 to provide ready access for removing a selected number of sheets while providing paper- retaining edge portions 32 to maintain the paper in an orderly state. One of the edge portions 32 is marked with a scale 34 which allows the user to judge an approximate number of sheets for removal.

Fig. 4 shows a suitable form of blank 40 for forming the carton 10. This example erects to provide an overlapping glued top 42 (Fig. 1) and a bottom 44 (Fig. 6) of interlocking tab formation. However, other forms of erection and closure well known in the carton art may equally be used.

Fig. 6 shows an example of blank 60 suitable for forming the trays 18. In this example, the tray is erected by folding and locked by location of tabs 62 in slots 64. The blank shown erects to a form in which both end walls are cut away but, as shown in Fig. 3, a form in which only one end wall is cut away is equally useful.

Referring now to Figs. 7 to 10, in a second embodiment a carton 100 is formed of any suitable material such as conventional carton board. The carton 100 is glued up from a one-piece blank to provide side walls 102a, b, c, d and a bottom 104 which may suitably be formed by interlocking flaps. The top of the carton 100 is formed by an inner side flap 106 which is pre-slit at 108, end flaps 110 and 112, and an outer side flap 114. The end flap 110 is of a length to extend to the slit 108, and has a plastic carrying handle 116 of known type secured to its inner face and passing through slots 118. The handle 116, in use, extends through a cut-out 120 in the outer side flap 114.

The carton is provided with tear strip tapes 122, 124 of fibrous material glued to its inner surface and operable by punched flaps 126, 128, the tear tapes 122, 124 being aligned at a forward edge of the slit 108. The tapes 122, 124 may suitably be "Clear Cut" tape by David S Smith.

In use, the carton is erected as seen in Fig. 7 and paper in trays is loaded into it from above. Typically, the carton will contain about 2,000 sheets of paper held in two, three or six open-topped trays. The flaps 106-112 are then glued and closed, to form the package seen in Fig. 8 which can be readily carried by the exposed portion of the handle 116.

When it is wished to use the paper, the tear tapes 122, 124 are operated to detach and remove a front portion of the carton 100, exposing the paper trays and allowing them to be removed from and replaced in the carton by lateral sliding movement, as seen in Figs. 9 and 10.

Fig. 9 shows a package using three trays 130, which are similar to the trays 18 of Figs. 1-6, and have a cut- away 132 in the leading edge. Fig. 10 shows a package using six trays 134. Since these are relatively shallow, no cut-away is used.

Different numbers and dispositions of trays could be used, for example three high or two side-by-side. The invention could also be implemented without the use of separate trays. For example, a single stack of sheets could be contained within a carton provided with a tear strip operable to remove the top and to form a cut-away portion in an end wall.
