Definitions

  • the present invention relates to sheets of material preferably wet wipes which are provided with an improved perforation configuration, which is easily visible to the consumer and which allows the wet wipes to be easily separated from oneanother whilst not compromising on strength.
  • 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 commonly used for human cleansing and wiping such as face and hand cleansing and anal, perineal and genital 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 constructed from combinations 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 wet wipes are then typically provided in a folded stacked configuration within a covered container such as a tub-like container having a lid.
  • the wipes may be provided in tub containers having a dispensing aperture. In both cases this allows easy transportation and storage of the wipes.
  • the wipes are packaged in a plastic foil in order to protect the wet wipes prior to use.
  • DE 27 06 234 discloses the use of perforated lines of variegated holes formed in a paper sheet, the diameter of which increases towards the edge of the paper so as to facilitate tearing of the paper by one hand.
  • perforations for wet wipes is particularly advantageous not only in terms of dispensing, but also in allowing the consumer to select the length or amount of wet wipe material required to carry out a particular clearing activity.
  • wet wipe stacking configuration which is suitable for multiple applications such as baby wipes and hard surface cleaning wipes which are strong, soft, absorbent and provide improved cleaning. It is further desirable to provide wet wipes whereby the wipe substrate is provide with perforated tear lines that are readily visible so that the consumer can select the desired length of wipe required and easily separate the wipes from oneanother, whilst providing sufficient strength so that the perforation within the wipe does not tear or break during use.
  • the present invention hence relates to a sheet of material, preferably a wet wipe for wiping parts of the human body such as baby wipes and other inanimate surfaces.
