SPECIFICATION A dispenser for sheet material

5 This invention relates to dispensers for sheet material, and in particular dispensers for facial tissues.

Cartons of the kind for dispensing sheet material which is folded on itself into an inverted U-shaped stack are known. The advantages of this kind of 10 carton compared to those which store the sheet material flat, is that they are more compact and require less packaging material and storage space. However, a drawback with cartons of this kind is that the stack of sheet material tends to shift during 15 transportation and use such that the sheets are not properly orientated with dispensing aperture, giving a potential dispensing problem. British Patent No. 1,186,787 shows a carton in which the stack of tissues is folded on itself. In this arrangement, the 20 end edges of the tissues are flared outwardly so that the bear against the side walls of the carton so as to support the stack and prevent it from shifting.

To help overcome the problem of shifting, it has been proposed to provide an insert within the carton 25 which supports the tissues. However, it is still possible for the insert itself to shift or for the sheets to become displaced from their correct position over the insert. British Patent No. 1,443,111 shows a carton having an inverted Y-shaped insert over 30 which the stack of sheets is folded. The insert causes the sheets to flare out so that the edges of the tissues bear against the side walls of the carton.

An object of the present invention is to provide a carton having an insert which improves the dispens-35 ing properties of the carton and which substantially reduces the shifting of the tissues in the carton during handling and transportation and which is itself prevented from being displaced.

According to the present invention there is pro-40 vided a dispenser for sheet material comprising a stack of sheet material, a carton having a base wall, side walls and a top wall, an aperture in the top wall through which the sheet material is dispensed, and support means within the carton for the stack of 45 sheet material, said support means comprising: a central member projecting substantially vertically upwardly from the base wall, over which the stack of sheet material is folded in the form of a symmetrical inverted U such that the top sheet of the stack is 50 presented to the aperture in the carton; means for supporting the end edges of the folded sheet material; and locating means locating the support means in position in the carton.

In this way the sheet material is supported in 55 position over the central member which is itself prevented from any substantial shifting within the carton, so that the sheet material is always presented to the aperture for extraction.

Preferably the means for supporting the end edges 60 of the folded sheet material comprises two wall members which project outwardly and upwardly from either side of the central member, at an angle to the central member, to opposite side walls of the carton, the said angle being advantageously depen-65 dent upon the bulk of the sheet material, the number of sheets, the number of plies in each sheet, and the folding configuration. Suitably these wall members extend upwardly from the base wall.

The whole end edge of each end of the stack is supported in this way since the angle of the two wall members can be varied to match the angle of the end edge of the stack according to the bulk of the sheet material used.

Preferably the said locating means comprises two members which project substantially horizontally from either side of the central member, along the base wall, to one of the said opposite side walls respectively.

In this way the central member and the two members for supporting the end edges of the stack are kept in position within the carton without the necessity for additional fixing. Other locating means may be provided, for example the wall members may be provided with tabs which are glued inside the carton.

Advantageously a plastic film member may be provided, extending across the aperture in the top wall, the said membrane having either an elongate overlapping opening or a slit depending on the nature of the substrate or the fold configuration used to permit extraction of the sheet material from the carton.

The plastic membrane helps to prevent the sheet material becoming soiled and may also assist in the dispensing action.

Advantageously the support means is a removable insert which is formed integrally from a cardboard blank.

The insert used can thereby be changed according to the bulk and length of the sheet material used and the dimensions of the carton.

Suitably the sheet material may be either interleaved, tab-tied or longitudinally folded.

The invention will now be described by way of example and with reference to the accompanying drawings in which:

Figure 1 is a perspective view of the dispenser according to the present invention,

Figure 2 is a cross-sectional side view of the dispenser along the line ll-ll of Figure 1,

Figure 3 is a view of the dispenser from above showing the plastic film membrane.

Figure4shows the blankforthe cardboard insert.

As shown in Figures 1 and 2, a dispenser for tissues 10 comprises a carton 20 having a base wall 25, side walls 30,31,32,33, a top wall 35 and a cardboard insert 40.

The top wall 35 is provided with an aperture 45 through which the tissues 10 can be extracted. A plastic film membrane 47 extends across the aperture 45 as shown in Figures 1,2 and 3. This membrane 47 has an elongate opening 50 which is originally sealed for example by perforations so that it can be opened by a user by tearing.

As will be described with reference to Figure 4, the insert 40 is cut and folded from a single piece of cardboard, and comprises a folded spine forming a central member 55 projecting vertically upwards centrally from the base wall 25, and two support members 60a, 606 projecting upwards from the

central member 55 at an angle A thereto. The upper edges of the support members 60a, 606 rest against the side walls 30 and 32 of the carton, and the insert also includes base members 65a, 656 extending 5 from the central member 55 horizontally along the base wall 25 respectively to the side walls 30 and 32. The configuration of the insert, with the outer edges of base members 65a, 656 and support members 60a, 606 engaging the side walls of the carton, 10 ensures a relatively rigid assembly which does not require the presence of tissues for support and which will not collapse during transitor use.

Although the spine 55 is shown as being vertical, it may be substantially vertical and comprise an 15 inverted V-shape, the central member 55 and the support members 60a and 606 thus combining to form an inverted W-configuration.

The tissues 10 are folded over the central member 55 in the form of a symmertrical inverted U, so that 20 the uppermost tissue 70 is presented to the aperture 45. The end edges 75 of the tissues 10 are supported by the support members 60a, 606. The height of the central member 55 should be not more than half the length of tissues 10, and preferably be slightly less 25 than half the length of the tissues 10. The angle A is dependent on the bulk of the tissue 10 used, the sheet count, the ply makeup and the fold configuration. A suitable angle would lie between 45° and 65°.

The tissues 10 of the stack are either interleaved, 30 tab-tied or longitudinally folded as is in itself known. In this way as the top tissue 70 is extracted the next tissue is pulled partially through the aperture 45 so that it can be grasped by a subsequent user.

In order that the first tissue of a new box can be 35 easily g rasped, the top sheet of a com plete stack is preferably folded over.

Figure 4 shows the blank 80 of the cardboard insert 40 before it is assembled.

To assemble the insert 40, the blank 80 is cut along 40 lines A', A", B', B" and C', C". It is then folded along line D and, in the opposite direction, along lines E between X'-Y' and X"-Y", and to a lesser extent along lines E between Y'-Y' and Y"-Y".

The length of the cuts A', C', A" and C" are half the 45 width of walls 31 or 33, although this may vary to take into account the board thickness and the clearance required during assembly.

The stack of tissues 10 can then be folded over the central member 55 and the assembly placed inside 50 the carton 20, where it is retained in position by abutment between edges B', B" of panels 65a, 656 and side walls 30,32.
