Definitions

  • the present invention relates to a supportive device which can be used time after time to support on its inner surface a disposable absorbent pad intended for one-time-use only, such that the supportive device and the absorbent pad together form an absorbent article, such as a diaper or an incontinence guard.
  • all-in-one diapers which are used once and then dis ⁇ carded. Such diapers are easy to use, fit snugly around the wearer, function well and are comfortable to wear.
  • An all-in-one diaper is less suitable from the aspect of waste-handling procedures, since the plastic pad supportive device and the absorbent pad form an integral unit which can only be divided up into its separate components with difficulty, for instance in a recovery system which is constructed for such separa- tion.
  • the object of the present invention is to provide a supportive device on which an absorbent pad, or absor ⁇ bent body, is supported so as together with said device form an absorbent article, such as a diaper, which from the aspect of use is equally as beneficial as an all-in- one diaper.
  • a supportive device of the kind defined in the introduction which, in accordance with the invention, is characterized in that elastic elements are provided on the inner surface of the sup ⁇ portive device, and in that said elastic elements extend over parts of an absorbent pad coacting with the sup- portive device in a manner to hold the pad firmly on said device. This will ensure that the absorbent pad is held correctly positioned on the supportive device and will also enable the absorbent pad to be placed in position on the device more easily.
  • the side edges of the inner surface of the supportive device are provided with leg elastication in the form of elastic bands which are extended to reach the front edge of the device so that in their extended state the elastic bands will also stretch over part of the absorbent pad.
  • the elastic bands also include transverse parts which extend over parts of the absor ⁇ bent pad in a manner to hold the pad firmly to the supportive device.
  • Figure 1 is a top view of an absorbent article which includes an inventive supportive device, that side of the device which lies nearest the wearer's skin in use facing towards the viewer;
  • Figure 2 is a cross-sectional view of part of the crotch region of the article shown in Figure 1, when the arti ⁇ cle is worn;
  • Figure 3 is a perspective view of an absorbent article which includes a supportive device constructed in accor- dance with another embodiment of the invention
  • Figures 4 and 5 are views similar to the view of Figure 1 and illustrate variants of the inventive supportive device in coaction with a T-shaped absorbent pad;
  • Figures 6 and 7 are views similar to the view of Figure 1 and show variants of inventive supportive devices in coaction with rectangular absorbent pads.
  • the absorbent article illustrated in the drawings is comprised of a T-shaped supportive device 1 in which there is inserted an absorbent pad 2, which is also T- shaped.
  • the device 1 can be used several times, whereas the pad 2 is intended for one-time-use only.
  • the device 1 is preferably made essentially of skin-friendly, liquid-impermeable but air-permeable material and the absorbent pad is preferably comprised of an absorbent core 3 embraced by an insulating layer 4 of good liquid- permeability.
  • This combination of supportive device material and absorbent pad material is suitable when the absorbent pad is homogenous from a structural aspect, or has a symmetrical structure in relation to a central transverse plane, such as to render unimportant how the absorbent pad is turned when inserting the same into the supportive device.
  • the insulating layer or sheet 4 of the absorbent pad will then extend solely on the upper side of the pad and the configuration of said layer will differ markedly from the configuration of the layer or sheet embracing the undersurface of the absorbent pad.
  • the choice of material from which the supportive device 1 is made depends to some extent on the construction of the absor ⁇ bent pad 2. For instance, it is not necessary for the supportive device material to be impervious to liquid when the layer or sheet which embraces the underside of the absorbent pad is impervious to liquid and extends beyond the edges of the absorbent core. It will there ⁇ fore be obvious that the invention is not restricted to the aforesaid choice of supportive device material, and that any appropriate supportive device material can be used.
  • the front part 5 of the supportive device 1 also in ⁇ cludes parts 6, 7 which are preferably, but not neces ⁇ sarily made of liquid-permeable material.
  • these parts 6, 7 are arranged on top of the T-shaped layer from which the supportive device 1 is essentially constructed, in the side components of the T, and are secured along the outer edges of said components or parts, on the inside of the supportive device, i.e. on the side facing towards the viewer.
  • the parts 6, 7 form together with said side parts of the T- shaped supportive device pockets which function to securely hold in position the T-shaped part of an absor ⁇ bent pad 2 inserted into the supportive device.
  • Elastic threads or bands 8, 9 are provided along the edges of the pocket openings.
  • Waist elastication 11 is provided along the edge of the rear supportive device part 10 in the form of an elastic band which extends beyond the side edges of the support- ive device 1, so as to form elastic attachment tabs 12, 13 which are intended to be secured to the outer side of the front part of the device, so as to give the absor ⁇ bent article a pants-like configuration when worn.
  • the fastener tabs 12, 13 include conventional fastener means which enable the tabs to be released from and refastened onto the outer surface of the front part of the device. Examples of appropriate fastener means include burr-type fasteners (Velcro tape), press-studs and adhesive devic ⁇ es.
  • Broad elastic bands 14, 15 extend along the side edges of the supportive device 1, from the back part of the device, over the crotch part 22 and slightly in on the front part 5 thereof.
  • the elastic bands 14, 15 are attached to respective side edges in a stretched state by means of respective narrow, longitudinally-extending joins 16 and 17, said joins being welded seams or glue joins, for instance.
  • the elastic bands 14, 15 may also be sewn to the supportive device 1.
  • the elastic bands 14, 15 include respective transverse parts 18, 20 and 19, 21 which extend transversely on both sides of re ⁇ spective joins or seams 16 and 17.
  • the elastic bands 14, 15 and the waste elastic are comprised of elastic foamed material enclosed in a supportive device that is made of skin- friendly, heat meltable non-woven fabric.
  • Figure 2 is a schematic illustration which shows part of the crotch region of the diaper illustrated in Figure 1, when the diaper is worn.
  • the contours of the thighs and crotch of the wearer are illustrated in broken lines.
  • the elastic band 15 lies tightly against the wearer's leg and adopts a generally vertical position. Because the elastic band 15 is relatively wide, the elasticity of the band may be chosen so that while the band tension around the leg is relatively slight, the proof of the article against leakage will not be jeopardized nevertheless .
  • the elastic bands are more rigid than the flexible support ⁇ ive device material, and consequently the upward move ⁇ ment (when the wearer stands up) or the upward and forward movement (when the wearer lies down) to which the article is subjected in the crotch region thereof when putting on the article will cause the elastic bands to pivot about the joins until the two transversely- extending parts 18, 20 and 19, 21 come into abutment with the inside of the wearer's legs. This ensures that the article is brought to its correct position.
  • This attachment of the elastic bands 14, 15 to the rear supportive device part is advantageous because the elastic bands 14, 15 at the rear supportive device part will hold the rear part of the absorbent pad 2 securely against the supportive device, since upward swinging of the transverse parts 20, 21 is thereby prevented in this part of the supportive device.
  • Figure 3 illustrates another embodiment of an inventive supportive device, here referenced 101, which differs from the supportive device shown in Figures 1 and 2 in that the elastic bands 114, 115 forming the leg elastic- ation solely extend in towards one another transversely in relation to the joins 116, 117, and thus only on one side of respective joins.
  • Those article components of the Figure 3 embodiment which correspond to similar article components of the Figure 1 embodiment have been identified with the same reference sign with the addi ⁇ tion of one-hundred.
  • the supportive device 101 of this embodiment is shown in coaction with an absorbent 102 inserted in said device.
  • the absorbent pad 102 of this embodiment has a length which makes it necessary to extend the elastic bands 114, 115, and therewith the supportive device 101, in order to enable the pad 2 to be inserted fully into the supportive device.
  • the elastic bands 114, 115 are allowed to contract, whereupon the composite article 101, 102 is deformed to the curved configuration shown schematically in Figure 3.
  • contraction of the elastic bands 114, 115 results in lifting of those parts of the sup ⁇ portive device which lie laterally outside the absorbent pad 102 in the crotch region of the article.
  • the elas- tic bands 114, 115 will also lift up and therewith form desirable liquid barriers.
  • the elastic bands of this embodiment will also lie directly against the wearer's thighs, thereby preventing the occurrence of the sup ⁇ portive device pleating or wrinkling between the wearer's legs and the leg elastication.
  • the elastic bands 114, 115 are also attached to the supportive device 101 at their respective front edges, more specif- ically to the pockets 106, 107.
  • Figure 4 and 5 illustrate further embodiments of an inventive supportive device, wherein those elements of these embodiments which correspond to similar elements in the Figure l embodiment have been identified with the same reference signs as those used in Figure 1, with the addition of a two-hundred prefix and a three-hundred prefix respectively.
  • the embodiments illustrated in Figures 4 and 5 differ from the embodiments illustrated in Figures 1-3 mainly in that the pockets 6, 7 and 106, 107 and their respective elastication 8, 9 and 108, 109 have been replaced with extended parts 208, 209 and 308, 309 of the leg elastication 214, 215 and 314, 315.
  • the longitudinally- extending joins 216, 217 and 316, 317 of respective leg elastications are terminated by outwardly-extending parts.
  • FIG. 6 Shown in Figure 6 is a supportive device 401 which supports a rectangular absorbent pad 402.
  • the front end of the pad 402 is inserted into a pocket 406 whose lateral extension is limited by joins 431, 432, such as weld seams or glue joins.
  • An elastic thread 408 extends along the edge of the opening of pocket 406.
  • Waist elastic 411 is used at the lower edge to hold the rear end of the absorbent 401. Accordingly, the waist elastic is fastened to the supportive device 401 by means of a transverse join 430, and the space beneath the elastic band 411 is limited transversely by joins 433, 434.
  • the rectangular absorbent pad 502 is held totally by the longitudinally- extending leg elastics 514, 515, which are extended to reach the front edge of the supportive device 501.
  • the pad By using elastic devices to hold an absorbent body firmly to the inventive supportive device, in the afore ⁇ said manner, the pad will be held securely in place in the supportive device when the diaper or the inconti ⁇ nence guard according to any one of the embodiments shown in Figures 1, 2-7 is placed on a wearer. Further ⁇ more, these elastic devices can be given a length which will enable them to be stretched from their relaxed state, or contracted state, to an extent such as to enable those parts of the absorbent pad which coact with the elastic devices to be readily inserted between said devices and the supportive device without jeopardizing secure attachment of the absorbent pad when placing the pad in the supportive device.
  • the manner in which elastic devices are used in accordance with the invention means that said devices need only extend over a small part of the absorbent pad in order to hold the pad securely. This fact permits the advantageous use of the transverse parts of the leg elastic to securely hold the absorbent pad.
