AUSTRALIA
Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant: CARTER HOLT HARVEY TISSUE AUSTRALIA PTY LIMITED Invention Title: MOIST TOILET WIPE The following statement is a full description of this invention, including the best method of performing it known to me/us: 2 MOIST TOILET WIPE This invention relates to moist toilet wipes and includes means for dispensing wipes of this kind.
Moist toilet wipes are a known product. There have been a number of past attempts to introduce wipes of this kind into the United States and European markets.
These products have received a lukewarm response from customers due to a number of factors that include ease of disposal, aesthetic appeal of dispensing devices and the wipes imparting excessive wetness, comfort, usability of the product, and the product not being environmentally friendly.
It is the past failures of this product and research into the factors that contributed to these failures that have brought about the present invention.
According to an aspect of the present invention there is provided a moist toilet wipe comprising a substrate of natural and synthetic fibres that is biodegradable and sewage dispersible, the substrate being impregnated with a liquor containing, emollient, and cleaning agent. The liquor may also contain a fragrance.
By sewage dispersible is meant that the wipe is flushable and can pass through the pipework associated with sewage disposal and passes through the initial screening process that removes solids from sewage waste.
The substrate is preferably a nonwoven fabric made primarily from cellulose. The substrate may include a small amount of synthetic fiber to increase its tensile strength.
In a preferred embodiment, the substrate basis H \ARymer\Keep\Speci\AJFW\moiet toilet wipe.doc 10/02/04 3 weight is approximately 55g/m 2 The toilet wipe is preferably rectangular measuring approximately 200mm by 150mm.
The liquor preferably includes approximately of active constituents that include emollient, cleansing agents, fragrance and preservative.
The purpose of the wet wipe liquor is to provide a moist cleaning and conditioning lotion and provide emollients to impart a smooth velvet-like feel without excessive wetness. Preferably the substrate is impregnated with liquor at an application rate of 180% of the substrate basis weight, that is at approximately 100g/m 2 The liquor preferably includes a preservative to prevent biological growth that would otherwise occur in the moist environment.
Preferably, the wipes are folded and located interleaved in a pack. Advantageously, a free edge of the top wipe is located through a specifically designed aperture in the pack whereby as the wipe is pulled clear of the pack by the free edge, the edge of the adjacent wipe is pulled through the aperture to pop up for subsequent removal.
In a preferred embodiment, the pack is designed to fit into a free standing or wall mounted dispenser.
Preferably, the dispenser defines a two part compartment in which a package of wipes is located, the upper part of the compartment having an aperture through which the pop up portion of the wipe projects, the compartment also including a lid that pivots down over the aperture when the dispenser is not in use.
Preferably, the dispenser is manufactured in H \ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 4 plastics and designed in a manner that it defines an aesthetically pleasing unit that is either free standing or can be mounted to a wall or related surface.
Embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings in which: Figures 1 and 2 show two folding patterns for packing moist wipes, Figure 3 is a perspective view of a moist toilet tissue dispenser showing a lid in an open position, Figure 4 is a perspective view of the dispenser with the lid closed, Figure 5 is a perspective view of the dispenser upside down with an upper part of the dispenser pivoted open, Figure 6 is a perspective view of the dispenser in the configuration of Figure 5 from above, and Figure 7 is a plan view of a blank from which a package for wipes can be folded.
The moist toilet wipe described hereunder has been specifically designed for personal use. The design of the product, its performance, dispensing and disposal are all important considerations in the design of the product. The product is intended as a supplement to dry toilet tissue and is designed with the following performance objectives: gives the consumer a cleaner feeling after use than dry toilet paper, fresher yet dry feeling after use than conventional moist wipes, is convenient and easy to use, is dispensed in a manner that enables the next wipe to be used while protecting unused wipes from drying out, 0 fits with the d~cor of most bathrooms, H \ARymer\Keep\Speci\AJFW\moiat toilet wipe.doc 10/02/04 5 is flushable and fully dispersible in municipal sewage systems, is suitable for use in septic systems, is biodegradable breaks down in normal sewage treatment processes).
THE WIPE In essence, the product comprises a substrate impregnated with liquor. The purpose of the substrate is to carry the wipe liquor whilst providing functional aspects: bulk, strength, and softness.
THE SUBSTRATE The substrate design ensures that it is: an appropriate size for the intended use, soft and silky to the touch, of sufficient strength to perform as required, absorbent, flushable gets around the S-bend), dispersible breaks up in sewage systems to prevent blockages in sewers and is not screened and therefore disposed to landfill), biodegradable.
The key characteristics of the substrate are that it is a nonwoven fabric made primarily from natural fibers. This ensures dispensability and absorbency. The substrate also contains a small amount of synthetic fiber to provide the desired tensile strength. The substrate is primarily cellulose that provides the biodegradability.
The substrate basis weight is preferably 55g/m 2 which defines the bulk, softness and absorbency. Finally, the H.\ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 6 substrate is produced as a rectangular sheet measuring approximately 200mm by 150mm thus providing enough cross sectional area for the intended use yet providing ready flushability.
As a result of extensive research it was decided to use as a substrate a product sold under the trade mark
HYDRASPUN
TM made by Ahlstrom. The product HYDRASPUN T M 8553 was selected with the following physical characteristics: Basis weight 55g/m 2 Thickness dry 570 microns Thickness wet 480 microns Dry tensile strength MD 570 N/m Dry tensile strength CD 270 N/m Wet tensile strength MD 160 N/m Wet tensile strength CD 100 N/m Flush index, tube test-first break 7 turns Flush index, tube test-many pieces 15 turns Absorption capacity 750% ISO brightness MD Machine Direction, CD Cross Direction WIPE LIQUOR The substrate described above was selected because it has superior liquor distribution and uniform retention of liquor thus offering a consistent liquid delivery per wipe.
In selecting the wipe liquor consideration was given to providing a moist cleaning and conditioning lotion whilst providing an emollient to impart smooth and velvet like feel without excessive wetness. At the same time the wipe had to provide superior performance compared with a dry toilet tissue. Due to the high celluloid content in the substrate and the presence of water in the HI\ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 7 wipe liquor further additives were required to preserve the wipes against biological degradation.
It was decided to provide a wipe liquor that had approximately 10% active constituents, the remainder being water. This higher than usual percentage of active constituents provided improved cleansing, emollient and moisture characteristics.
The selected formulation of listed hereunder: the wipe liquor is CHEMICAL TRADE NAME W/W PROPERTIES

It was decided to impregnate the substrate with liquor at an application rate of 180% of the substrate basis weight. This liquor application rate provided the appropriate level of wetness.
The preservative was added to avoid the growth of micro organisms such as molds, fungi, yeasts and bacteria.
Although the preferred embodiment includes fragrance it is understood that a non-fragrant wipe is also envisaged.
PACKAGING, DELIVERY AND DISPENSING Having selected the substrate and liquor formulation consideration was given to the packaging and dispensing of the moist wipes.
It was decided to package the moist wipes so that they could be dispensed using a pop up delivery system. The packaging protects the wipes from damage and biological attack and seals in the moisture. The packaging was designed to function both as a refill for a bathroom dispenser and as a travel pack for away from home use. The packaging was designed so that it could dispense wipes from both an upright and side on orientation.
It was thus decided to design packaging in the form of a pack formed from a soft plastic film 60 as shown in Figure 7 with a resealable dispensing aperture 61 enabling the wipes to retain their moisture when used in a travel pack application. Dispensing of the wipes was by a pop up delivery system whereby the wipe being dispensed Ht\ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 9 pulls part of the next wipe from the pack, providing a start tab for the next use. This dispensing technique was achieved by employing an appropriate folding method that partially interleaves the wipes. Two such folding patterns are illustrated in Figures 1 and 2. In Figure 1 each wipe 1 has an elongate straight portion 2 with a zigzag fold 3 at one end. As shown in Figure i, the wipes are then interleaved with the zig-zag portions 3 engaging the free end 4 of the straight portion.
In the alternative folding pattern shown in Figure 2, the wipes 5 are folded in a zig-zag configuration uniformally along their length with the overlapping ends 6 7 interlocked. Clearly, the two folding patterns define difference package sizes but both have the effect of allowing a pop up delivery system whereby as a first wipe is pulled through an aperture in the package, the pop up tab of the adjacent wipe projects through the aperture enabling the subsequent wipes to be removed. Preferably a 40 sheet pack is provided with the dispenser with a 50 sheet pack being provided as a refill.
As shown in Figure 7 the pack is folded from a plastics blank 60 that has specific fold liens 62, 63, 64, 65. A central aperture 61 of oval shape is covered by a peal off strip 66.
A critical factor associated with the pop up feature is the size and shape of the aperture 61 through which the wipe is delivered. The aperture is sized to facilitate pop up of subsequent wipes whilst enabling the initial wipe to be pulled free from the pack. The zig-zag end portions of the wipe are also designed to minimise the amount of wipe that is projecting out of the package thus reducing the likelihood of loss of moisture.
In a travel pack application, the package is H \ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 10 used on its own with, as mentioned above, a removable soft plastic film 66 that can be resealed across the aperture 61 to ensure that the wipes retain their moisture.
The package is also designed to fit within a dispenser, details of which are illustrated in Figures 3 to 6.
The dispenser 10 comprises a base portion 11, top portion 12, lid 13, and mounting bracket 14. The dispenser 10 is generally of rectangular configuration but with the outer surface of the top portion 12 being convexly curved to improve the aesthetic qualities of the dispenser. The lid 13 which is pivotally secured to the top portion 12 conforms to the overall shape of the top portion 12 when closed as shown in Figure 4.
As shown in Figures 5 and 6, the base portion 11 defines a base 15 with a front and rear wall 16 and 17 bordered by side walls 18 and 19. The walls define a rectangular enclosure which is adapted to accommodate a package of wipes (not shown). The top portion 12 has a rear face 21, front face 22, and sides 23 and 24. The rear face 21 is hinged to the rear 17 of the base portion 11 via flanges that are formed on the edge surfaces of the respective portions. The hinged association of the two components allows them to be maneuvered into a release position (not shown). When hinged together the dispenser can be opened, as shown in Figures 5 and 6, allowing easy access to the interior for removal or insertion of a pack of wipes.
The upper surface of the top portion 12 is provided with an oval recess 30 that in turn defines a shamrock shaped aperture 31 defining three lobes 32, 33, and 34. The aperture 31 is surrounded by a peripheral upstanding wall H \ARymer\Keep\Speci\AJFW\moist toilet wipe.doc 10/02/04 11 A cutout 36 is provided across an arcuate portion of the forward wall of the recess 30 that has the effect of allowing the lid 13 to spring against the forward projection of the wall, thus providing a simple and effective latching mechanism. The lid 13 is hinged to a rear portion of the upper surface of the top 12 and has a pair of parallel downwardly extending skirt portions the first 40 of which is a close fit within the wall of the recess 30 and the second of which engages the upstanding peripheral wall 35 that surrounds the aperture 31. In this manner when the lid 13 is closed, as shown in Figure 4, the abutting contact of the skirt portions with the walls ensure a substantially air tight seal.
As shown in Figure 4, the front 42 of the recess in the top portion 12 is scalloped to provide a ready access to the lid allowing the lid to be pivoted open as shown in Figure 3. The forward wall of the top portion 12 is also provided with a downwardly extending tab 43 that extends over the front wall 16 of the base portion 11 to allow simple access to prize the two portions 11 12 apart.
The underside of the base 15 of the base portion 11 has a rectangular mounting bracket 14 which has lateral flanges 51, 52 that are arranged to locate within grooves formed in the underside of the base 15. If the mounting bracket 14 is secured to a wall using the screws 53 illustrated in Figure 5, the base portion 11 of the dispenser 10 could then be slid onto the flanges 51, 52 to thereby hold the dispenser 10 in parallel abutting contact against a wall surface. The flat base of the dispenser also allows it to assume a free standing role and spaced legs (not shown) facilitate support of the base. It is understood that double sided tape could also be used for wall mounting of the mounting bracket.
H \ARymer\Keep\Speci\AJW\moiat toilet wipe.doc 10/02/04 12 The shamrock shaped aperture 31 in the top portion 12 of the dispenser 10 aligns with the aperture in the top of the package and is designed so that the start tab of the top wipe can be pushed through the aperture so that a wipe can be removed from the dispenser 10 by a pull on the start tab which in turn pulls the wipe from the package that is contained in the dispenser.
The moulds used to manufacture the dispenser are treated with an anti-static material that has the effect of inhibiting the attraction of dust to the surfaces of the dispenser, thus further enhancing its aesthetic qualities.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
