Definitions

  • the present invention relates to a disposable diaper having a soft, fluid absorbing body or pad to be placed between the baby's legs.
  • the diaper is mainly characterized in that one of the ends of the absorbing body has a cross portion widening said end and intended to be placed on the front of the baby above the legs and being stable in form when either wet or dry.
  • the diaper has a greater absorption capacity in the critical front part, thus avoiding leakage.
  • a liquid impervious layer possibly lined with e.g., a non-woven textile, so that the wet surface area of the diaper in contact with the babys skin will be decreased.
  • DISPOSABLE DIAPER Many different types of disposable diapers are known. Some consist of an extended, lmost square absorption body with recessed edges for the childs legs and with about 30 to 45 cm long sides. They are designed to be held in place around the lower part of the childs trunk by safety pins, tape or other fastening means, without the help of a diaper cover or other such aids since the outside of their absorption bodies can be provided with a fluid impervious layer. With the use of such diapers, a large portion of the childs body will be wrapped up in soaked material. This is obviously disadvantageous since the fluid is mainly the urine excreted by the child.
  • This embodiment consists, in principle, of a soft, rectangular concentrated wet body 30 to 40 cm long and to 13 cm wide and having an even thickness of one or a couple of cm.
  • This design is intended to be used together with a diaper cover in the form of a pant, triangular diaper-holder or the like, whereby the cover is secured around the pertinent part of the childs body and holds the diaper in place.
  • this type of diaper is securely united with the diaper cover which, however, is always considerably larger than the daiper itself.
  • the object-of the prevent invention is to remove the above noted drawbacks and provide a disposable diaper having a soft, fluid absorbing body or pad, designed to be placed between the legs of the baby. Besides minimizing the area of contact with the skin of the child and being capable of providing, under all conditions, absorption where it rests against the front of the babys body thereby avoiding leakage from the front, the new diaper is also capable of remaining in the proper position on the baby after it has been put
  • a diaper according to the invention and providing the advantages set out above is chiefly characterized in that the fluid absorbing body or pad in the area of one of its ends has a cross portion widening said end and intended to be placed on the front of the baby above the childs legs and which is stable in form when either wet or dry.
  • this portion can be made thicker than the other parts of the body or pad. It is also particularly advantageous from the stability point of view to have an elastic insert in the absorption material within the corss portion of the body, e.g., in the form of a foam plastic filler.
  • the absorption material can be fixed, at least in the cross portion, by a binder, e.g., acryl.
  • a strengthening insert in the body, at least in this transition area.
  • the diaper can be made to conform nicely to the childs body if the strengthening insert is resilient and consists of e.g., a plastic mesh.
  • a diaper made according to the invention consists of a fluid absorbing body in form of a T.
  • This diaper is designed to be used together with a diaper cover such as a pant, a diaper holder or the like.
  • the fluid absorbing body or pad is soft and includes a conventional absorption material l, e.g., defibred cellulose enclosed in a similarly conventional wrapping 2 of e.g., water transmitting, non-woven fibrous material.
  • the wider part 3 of the diaper i.e., that part which forms the crown in the T-shape
  • the narrower part 4 i.e., that part which forms the stem in the T-shape
  • the diaper will effectively counteract said sliding or displacement due to its geometric shape and its form stability. The diaper will instead retain its correct position against the babys body when in use.
  • the wider part of the diaper is put on the frontof the baby above the legs, a greater part of the absorption material will be advantageously situated relatve to the child's urethra. Moreover, this advantage can be utilized to an even greater degree by making the wider diaper part 3 thicker than the narrow part 4 between the babys legs.
  • the form stability of the diaper is especially good, partly because the absorption material in the wider part 3 is secured by a binder, e.g, acryl, and partly because an elastic insert in the form of a plastic mesh 5 is placed inside said absorption material 1 within said wider part 3.
  • this insert can consist of e.g., foam plastic or another elastic material.
  • the plastic mesh Sis so shaped that it extends into the absorption material of the narrower diaper part with a terminating portion 6 originating from its main part in the diaper part 3.
  • This portion 6 also serves as a type of reinforcement for said transition area.
  • a liquid impervious layer of e.g., plastic, possibly lined with a non-woven textile or the like for lessening the area of the plastic surface next to the skin can be arranged to partially cover this portion of the diaper, at least on that side of the diaper which is intended to be in contact with the babys skin.
  • a disposable diaper having a soft fluid-absorbing body or pad to be placed between the childs legs, characterized in that the area at one end of said body or pad has a cross portion widening said end and intended to be placed on the front of the child above the legs, means to stabilize said cross portion in form in both a wet and a dry state, said stabilizing means being disposd internally of said diaper and extending both in said cross portion and in the portion to be placed between the childs legs, and a cover encasing said body or pad, said cover being liquid-pervious over at least a portion of the side of the diaper that is against the child.
  • a diaper according to claim 1 characterized in that the cross portion of the absorbing body is thicker than its other portions.
  • a diaper according to claim 1 characterized in that said means comprises an elastic insert in the absorption material, e.g., in the form of a foam plastic tiller.
  • a diaper according to claim 1 characterized in that the absorbing body compriss a strengthening insert, at least within the transition portion between the cross portion and the narrower parts.
  • a diaper according to claim 1 characterized in that the side of the cross portion of the absorbing body in contact with the childs skin when used is partially covered by a liquid impervious layer of e.g., plastic,
