Definitions

  • the present invention relates to a dispensing system for wet wipes comprising a container and a stack of wet wipes therein which deliver an improved pop-up dispensing of an individual wipe from the wet wipe stack.
  • Wet wipes are typically premoistened, disposable towelettes which may be utilised in a variety of applications both domestic and industrial and perform a variety of functions.
  • Wet wipes are typically used to wipe surfaces both animate and inanimate, and may provide numerous benefits such as cleaning, cleansing, disinfecting, and skin care benefits.
  • Wipes are also commonly used for human cleansing and wiping in general such as anal, perineal and genital cleansing and face and hand cleansing for example as intimate hygiene wipes such as feminine wet wipes.
  • Wet wipes may also be used for application of substances to the body including removing and applying of make-up, skin conditioners and medications.
  • Another application of wipes is during diaper changes and also for the treatment of adult and baby dermatitis partly caused by the use of diapers and incontinence devices.
  • wet wipes are also applicable for wiping and or cleaning other surfaces or for the application of compositions to surfaces, for example kitchen and bathroom surfaces, eyeglasses, shoes and surfaces which require cleaning in industry for example surfaces of machinery or automobiles.
  • Wet wipes also include articles used for the cleaning or grooming of pets.
  • wet wipes are commonly provided as a structure of a combination of synthetic and natural fibres, such as polyolefin fibres, viscose fibres and cotton fibres, which are generally moistened with an aqueous composition which contains amongst others surfactants, preservatives, oils and scents.
  • the wipes are then typically packaged in a container in order to facilitate easy transport and storage.
  • multi wipe containers There are two basic types of containers for such wet wipes namely, multi wipe containers and single wipe packages.
  • a flexible or rigid moisture impervious container is utilised, the wipes being folded and stacked in such an arrangement therein, so that a single wipe is exposed to and removed by a consumer at one time.
  • These containers have a tub like configuration or a flexible rectangular package, both of which are typically resealable after opening.
  • a problem with the current wet wipes products is the lack of easy, single wipe dispensation from the wet wipe stack and or the container. This problem is particularly acute in circumstances of use such as when a consumer is holding a baby during a diaper change. Under such conditions the consumer readily needs to be able to pick up and separate one wipe from the container and the stack which is unfolded, using only one hand and without the wipe container being raised from the surface on which it is placed during the removal action. This however is not achieved satisfactorily with current products.
  • wet wipes are typically folded and either placed one on top of the other or interleaved with an adjacent wipe and placed one on top of another to form a stack.
  • the exact location of the leading edge of the upper most wipe of current stacks is however not easily identifiable, either visually or tacitly. This is because the substrate material of the wipe is typically homogeneous and thus the leading edge of the wipe, particularly when folded, cannot be distinguished from the wipe substrate material on which it rests.
  • the leading edge portion of the wipe also has a tendency to adhere to the underlying wipe substrate material on which it rests. Hence even tactile identification of the edge by running or dragging of the fingers across the wipe surface does not immediately result in the identification of the location of the edge.
  • leading edge Once the leading edge has been located, it is difficult for the consumer to grasp hold of sufficient substrate material and maintain grasp thereof, in order to separate a single wipe from the stack upon which it rests. The consumer often is only able to grasp a small portion of the leading edge such that a tight grip thereof is not established and hence the wipe easily slips from the fingers of the consumer.
  • the adjacent wipe is also at least partially separated from the stack.
  • the consumer is required not only to unfold the wipe before commencing with the desired application of the wipe but also, to separated it from the adjacent wipe in the stack and returned this wipe to the stack in the container. This is obviously particularly inconvenient to consumers utilising baby wipes during diaper changes.
  • EP 747 313 proposes a means to address this problem and discloses a multiple folded paper, such as wetted tissue paper, for continuous disposal through a container orifice. In this manner a maximum of a quarter of the length of the adjacent wipe is exposed through the dispensing orifice.
  • wetted tissue products cannot be utilised for all wet wipe applications, such as baby wipes, as the wetted tissue paper is not satisfactory in terms of softness or strength.
  • wetted tissues suffer from a tendency to tear during use and hence are not suitable for use as wet wipes.
  • pop-up dispensers to improve dispensing.
  • These dispensers are comprised of a container having an upper panel having an orifice.
  • the pop-up dispensers function on the principle of providing a dispensing orifice which is relatively small, and which is sized and configured so that in combination with a stack of wipes having a particular folding configuration so that the upper portion of the adjacent wipe is held within the dispensing.
  • These containers are thus designed such that during the removal action of the upper most wipe from the container through the aperture, the adjacent wipe is elevated from the stack such that it partially protrudes through the orifice once the upper most wipe has been removed. In this manner the uppermost wipe is positioned for easy grasp by the consumer.
  • These type of pop-up dispensers allow the wipes to be provided either on a continuous roll with perforations therein or as separately folded wipes as for example described in US 5,560,514.
  • dispensers with typically very small dispensing apertures is not considered desirable by the consumer.
  • small orifices prevent the consumer from being able to see and examine the inner contents of the container and estimate the number of wipes remaining therein.
  • pop up failure occurs and the wipe adjacent to the dispensed wipe is not elevated from the stack, due to the small dispensing orifice size the consumer is unable to easily feed the wipe through the dispensing orifice and is required to dismantle the dispenser itself
  • a similar problem is encountered if the consumer inadvertently removes too many wipes than required from the dispenser and attempts to push them back into the dispenser.
  • the present invention hence relates to a wet wipe for wiping parts of the human body such as baby wipes and other surfaces.
  • the present invention relates to a pop up wet wipe dispensing system so as to facilitate ease of dispensation and separation of a single wipe from the stack of wet wipes within a dispensing container throughout the diminishing height of the stack.

  • the wipes have an average separation force between two wipes as defined by the test method herein of from 75 g/cm 2 to 250g/cm 2 .
  • the wet wipe comprises a substrate which is coated or impregnated with a liquid composition.
  • the substrate may be woven or nonwoven, foam, sponge, battings, balls, puffs or films, most preferably a nonwoven and may be composed or natural or synthetic fibres or mixtures thereof.
  • the fibre compositions are a mixed of hydrophilic fibre material such as viscose, cotton, or flax and a hydrophobic fibre material such as polyethylene tetraphthalate (PET) or polypropylene (PP) in a ratio of 20%-80% hydrophilic and 80%-20% hydrophobic material by weight.
  • PET polyethylene tetraphthalate
  • PP polypropylene
  • Two particularly preferred compositions are 50% viscose / 50%PP and 50% viscose / 50 % PET.

  • the substrate calliper is measured according to standard EDANA non woven industry methodology, reference method # 30.4-89.
  • the bulk density of the substrate is preferably not more than 1.0 g/cm 3 , preferably not more than 0.9 g/cm 3 , most preferably not more than 0.7 g/cm 3 .
  • the substrate can have other components or materials added thereto as known in the art.
  • the types of additives desirable will be dependent upon the particular end use of the substrate contemplated.
  • wet wipe products such as moist toilet paper, paper towels, facial tissues, baby wipes and other similar air laid products
  • wet strength resins it is often desirable particularly for cellulose based substrates to add chemical substances known in the art as wet strength resins.
  • the substrate may also comprise agents to improve the optical characteristics of the substrate material such as opacifying agents, for example titanium dioxide.
  • the substrate may be produced by any methods known in the art.
  • nonwoven substrates can be formed by dry forming techniques such as air-laying or wet laying such as on a paper making machine.
  • Other nonwoven manufacturing techniques such as melt blown, spun bonded, needle punched and spun laced methods may also be used.
  • a preferred method is hydroentangling.
  • the substrate may be comprised of one or a multiplicity of layer, preferably two or three layers of material. These layers may be identical in terms of composition and or manufacturing techniques or a combination of any of the materials described herein above. Preferably one of the layers may be a scrim reinforcing layer, as described for example in US Patent Application serial number 09/133294.
  • the substrate of the wet wipe has a central panel and two opposing end edge panels, a leading edge panel and a trailing edge panel.
