Abstract
The wipes 1 are formed from a continuous length of material 2 with parallel side edges 2A,2B having a leading end 3A and a trailing end 3B. Ruputurable lines 4 are spaced along the length of material separating each wipe 1. The tear lines 4 extend from a point 5A on one first side edge 2A to a point 5B on the other second side edge 2B. Preferably, the perforated lines 4 are angled relative to the sides 2A 2B or curved. Each tear line 4 preferably comprises a series of slots 6A-6F which get progressively shorter or less frequent. Therefore, each rupturable line 4 is more easily ruptured adjacent the second side edge 2B than the first side edge 2A. Preferably the dry-wipes or wet-wipes comprise optionally impregnated, non-woven fabrics.
Description
Title: Wipes The present invention relates to wipes.
Wipes are usually formed from a continuous length of impregnated non-woven fabric with parallel side edges, and lines of rupturable perforations equally spaced along the length of the fabric with each line normal to and spanning the width of fabric between the side edges. Each wipe is thus formed between lines of perforations.
Such wipes are often packaged in a tub and dispensed through a tub aperture. As a wipe is drawn through the aperture the perforations rupture so separating an individual wipe from the rest of the length of wipes, and the leading edge of the next wipe is left projecting through the aperture to be pulled out of the tub when the next wipe is to be used.
A problem with such wipes is that the perforations between wipes can rupture before the leading edge of the next wipe is left projecting through the aperture, so a user cannot withdraw another wipe without opening the tub and feeding the next wipe through the aperture. Alternatively the perforations rupture just as the leading edge of the next wipe projects through the aperture, but there is insufficient length of the leading edge to be grasped to withdraw the next wipe.
An example of an improved method for ensuring that a tail or presentment' is made available for the next user is described in US 20020074375A 1. The wipes feature a perforated region along its length with cut' regions on one or both sides of the perforated region. The perforations in the perforated region are uniform along their length and require the same strength to rupture them at any point along their length. As the wipe is drawn to the opening of the container, these cuts cause areas of the wipe to bend backwards and catch with the opening. These distorted areas necessarily become catch flaps. This causes enough tension in the perforated region which is now outside the opening of the container to break the dispensed individual sheet free. The wipes emerge from a slit-like dispensing opening, the mechanism for separating the wipes being the action of catch flaps engaging with the slit like opening. This method applies to a pop-up wipe dispensing system with wipes being dispensed from the outside of the roll of wipes contained within the dispenser.
In the case of a tub of wipes, the continuous length of material emerges from the centre of the web in a generally twisted, tube-like format which will not of necessity allow for catch flaps to be formed from cut sections because the cut sections which formed the catch flaps as detailed in US 20020074375A1, become part of the twisted tube-like arrangement. A different mechanism is therefore required to encourage wipes dispensed from a tub to separate into individual sheets.
US2002 155246 shows wipes with perforations perpendicular to the wipe side edges, but the perforations are as easy on one side edge to rupture as on another, although a given line of perforations may have a variable degree of rupturability across its length. Also it does not show a rupturable line which is progressively more difficult to rupture along its length from one second side edge to another side edge.
The invention seeks to provide a solution to this problem.
According to the present invention there is provided wipes formed from a continuous length of material with parallel side edges having a leading end and a trailing end, and ruputurable lines spaced along the length of material separating each wipe, said rupturable lines extending from a point on one first side edge to a point on the other second side edge, and each rupturable line being more easily ruptured adjacent the second side edge than the first side edge.
In one embodiment the point on the other second side edge is further towards the trailing end.
In another embodiment the rupurable lines are perpendicular to the side edges.
Preferably in use, when a rupture is initiated at the second side edge, the rupturable line continues to rupture towards the first side edge.
Preferably each rupturable line is progressively more difficult to rupture along its length from the second side edge to the first side edge.
Preferably the material is a non-woven fabric. The material may be impregnated. The wipes may be wet or dry.
Preferably the rupturable lines are formed from apertures or slots in the material. In one embodiment slots are provided and the slots are longer adjacent the second side edge. In another embodiment apertures are provided and the apertures are greater in frequency adjacent the second side edge.
Preferably the rupturable lines are straight lines. Alternatively they may be curved, wavy or any other non straight orientation.
The invention also extends to a container of wipes as defined above adapted to be dispensed through a container aperture. Preferably each rupturable line ruptures only when a point on the other second side edge emerges from the container aperture, whereby when one wipe is removed by rupturing the line between it and the next wipe, the leading edge of the next wipe extends out of the aperture.
The container of wipes may be of the type described in patent application nos GB 0710596.8 and GB0617067.4, the contents of which are hereby incorporated herein.
An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a plan view of a first embodiment of wipes, Figure 2 shows a wipe separating from the leading edge of a wipe emerging through a tub aperture, Figure 3 shows a plan view of a second embodiment of wipes, and Figure 4 shows a plan view of a third embodiment of wipes.
Referring to Figure 1 there are shown wipes 1 formed from a continuous length of material 2 with parallel first and second side edges 2A,2B having a leading end 3A and a trailing end 3B.
Ruputurable straight lines 4 in material 2 are spaced along the length of material separating each wipe I. Each rupturable line extends from a point 5A on first side 2A edge to a point SB on the other second side edge 2B further towards the trailing end.
As shown, each line 4 is formed from slots 6A,6B,6C,6D,6E,6F which progressively reduce in length so that slot 6A is the longest and slot 6F the shortest. Each line 4 is thus more easily ruptured adjacent the second side edge 2B than the first side edge 2A, and each line 4 is progressively more difficult to rupture along its length from the second side edge to the first side edge.
The wipes I may be formed of any suitable material, such as a non-woven fabric or paper, and may be impregnated as is well know in the art. The wipes may be wet or dry.
Referring now to Figure 2, there is shown a tub 10 housing and dispensing wipes 1 of the type shown in Figure 1 through a nozzle or aperture 11.
As the first wipe I is withdrawn from the nozzle, it pulls with it the next second wipe until the point 5B on second edge 2B emerges out of the nozzle. The friction of the nozzle is not great enough such that the rupturable line 4 starts to rupture adjacent point SA, but is great enough to cause the onset of ruptures at point 5B. Once started, the rupturable line continues to rupture back towards the first side edge. When the first wipe has separated from the next second wipe, the leading edge of the next wipe to be withdrawn extends fully out of the aperture so it can be gripped easily.
Referring to Figure 3 there are shown wipes 21 formed from a continuous length of material 22 with parallel first and second side edges 22A,22B having a leading end 23A and a trailing end 23B.
Ruputurable straight lines 24 in material 22 are spaced along the length of material separating each wipe 21. Each rupturable line extends from a point 25A on first side 22A edge to a point 25B on the other second side edge 2B, and each rupturable line is at right angles or perpendicular to the side edges.
As shown, each line 24 is formed from slots 26A,26B,26C,26D,26E,26F which progressively reduce in length so that slot 26A is the longest and slot 26F the shortest. Each line 24 is thus more easily ruptured adjacent the second side edge 22B than the first side edge 22A, and each line 24 is progressively more difficult to rupture along its length from the second side edge to the first side edge.
The wipes 21 may be formed of any suitable material, such as a non-woven fabric or paper, and may be impregnated as is well know in the art. The wipes may be wet or dry.
Referring to Figure 4 there are shown wipes 31 formed from a continuous length of material 32 with parallel first and second side edges 32A,32B having a leading end 33A and a trailing end 33B.
Ruputurable wavy lines 34 in material 32 are spaced along the length of material separating each wipe 31. Each rupturable line extends from a point 35A on first side 32A edge to a point 35B on the other second side edge 32B, and each wavy rupturable line is generally at right angles or perpendicular to the side edges.
As shown, each line 34 is formed from slots 36A,36B,36C,36D,36E,36F which progressively reduce in length so that slot 36A is the longest and slot 36F the shortest. Each line 34 is thus more easily ruptured adjacent the second side edge 32B than the first side edge 32A, and each line 34 is progressively more difficult to rupture along its length from the second side edge to the first side edge.
The wipes 31 may be formed of any suitable material, such as a non-woven fabric or paper, and may be impregnated as is well know in the art. The wipes may be wet or dry.
The invention may take a form different to that specifically described above. Instead of slots of varying length, uniform apertures could be provided which are greater in frequency adjacent the second side edge. Instead of the lines 4 being straight lines, they could be other shapes such as curved, wavy or any other non straight orientation.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
