## Background
CROSS REFERENCE
The present application is a continuation of U.S. patent application Ser. No. 11/813,588, now U.S. Pat. No. 7,954,665, having a Sep. 20, 2007 date of completion of all 35 U.S.C. §371 requirements for a national phase of International Application No. PCT/GB2005/004972 filed Dec. 20, 2005.


BACKGROUND
This invention relates to wipes. The term “wipes” is used herein to refer to the kinds of disposable absorbent products known variously as tissues, cloths, paper towels, kitchen roll and the like, which may be made of paper, cloth or any other suitable material and which may be moist, wet or dry and which may be embossed, perforated, quilted or printed or have any other surface decoration or treatment.
Conventional products of this nature, and the dispensers in which they can be stored, are typically not very attractive to look at. Also it is often necessary to use two hands to extract the product from its dispenser. The present invention seeks to improve upon these existing products.
The invention provides a wipe comprising a generally flat piece of material in which said piece of material is formed into a non-planar form having a three-dimensional shape for storage in said shape.
The invention also provides a dispenser for storing a multiplicity of wipes, wherein the dispenser has a body which is adapted to suit the three-dimensional shape of the wipes.
The invention further provides a method of making wipes comprising the steps of producing a generally flat piece of material, forming the piece of material into a non-planar form having a three-dimensional shape and storing the piece of material in said shape.



DESCRIPTION OF THE DRAWINGS
By way of example, embodiments of the invention will now be described with reference to the accompanying drawings, in which:
FIGS. 1a, 1b and 1c show a wipe according to the invention in its various stages of formation, and
FIGS. 2, 3 and 4 show various forms of dispensers suitable for storing the wipes of FIG. 1c. 



DESCRIPTION OF THE PREFERRED EMBODIMENTS
The wipe shown in the drawings is formed initially as a flat round disc 10 of material (FIG. 1a). The wipe may comprise a single layer of material, or it may have two or more plies of the same or different materials. Here, the wipe has a laminated construction, with a lower layer 10a of absorbent material, such as paper or the like, and an upper layer 10b of impervious material, such as glacene paper. Each of the layers 10a, 10b may comprise one or more plies. The wipe may be impregnated, for example with a scent and/or possibly with an antibacteriological agent. The disc 10 may be formed by any suitable process, such as by being cut from a web of material produced in a continuous process on a machine.
As seen in FIGS. 1a, 1b and 1c, the wipe is transformed from the planar form of disc 10 seen in FIG. 1a into the three-dimensional form 11 seen in FIG. 1c by tucking in a pleat 13 formed by two radial fold lines 14, 15 in the disc 10. The pleat 13 enables the disc 10 to be partially wrapped over itself, as seen in FIG. 1b, which has the effect of drawing it into a conical configuration, as seen in FIG. 1c. 
By the nature of the material of which it is made, the wipe will tend to remain in its conical configuration once formed, and a number of wipes can thus be stacked one upon another in this configuration. There will be a tendency for the pleat 13 to protrude slightly from the wipe's conical profile, and this provides a useful provision by which a user can readily grasp a wipe from a stack. It will be noted that this can be done using only one hand. When a wipe is to be used to mop up a spillage of liquid on a kitchen top, for example, it can be lifted from a stack by its pleat 13, carried to the spill and simply dropped onto it. When dropped, the wipe will tend to unwrap and return to its original planar form. This transformation will be assisted as the lower layer 10a begins to absorb the liquid from the spill. When all the spilt liquid has been absorbed (or when the wipe has become saturated), the wipe can be lifted and disposed of. In this process, the upper layer 10b ensures that the user's hand does not become wet or soiled.
Various dispensers suitable for storing the wipes of FIG. 1c are seen in FIGS. 2, 3 and 4. The dispenser of FIG. 2 comprises an essentially round hollow cylindrical body 16 with an internal diameter roughly equal to the overall diameter of the wipes when in their conical form of FIG. 1c. A vertical slit 17 in the container body allows access to the pleat 13 of the uppermost wipe in the stack for grasping by a user.
The dispenser of FIG. 3 is in the nature of a free-standing support, with a base 18, a stem 19 and a head 20. The head 20 has a conical configuration to suit the conical configuration of the wipes, which sit upon it.
The dispenser of FIG. 4 is similar to that of FIG. 3 in that it has a conically-shaped head 20 on which the wipes are stacked. Here, however, the head 20 is attached by an elbow 21 to a bracket 22 which enables the dispenser to be mounted on a wall.
A stack of wipes stored and presented in the manner described above offers a more attractive solution for a kitchen than the more traditional forms of paper roller. The arrangement also facilitates use of the wipes, because they can be picked up with just one hand, unlike removing a tissue from a conventional roll of kitchen paper, which often requires two hands. Furthermore, the material and form of the wipe maximise its efficiency and ease of use.
It will be understood that the wipe may be formed initially in any suitable shape, not necessarily a geometric shape, and that it may also be formed into any suitable three-dimensional shape, again not necessarily a geometric one.

## Claims
