HUT72150A - Absorbing article of the diaper or insert type - Google Patents

Description

The present invention relates to absorbent products of the diaper or lining type.

Previously, such articles (clothing) were generally made from simple pieces of cotton fabric, which were often washed and reused after each wash. However, the cotton cloth pieces had to be applied in several layers to provide the desired absorbent capacity (absorption capacity), so that the manufactured products were heavy and bulky and costly to wash. It is well known that development has led to the proliferation of disposable products that have high absorbency but are not bulky. Such products have been made possible by so-called superabsorbent fillers.

Currently, the use of the subject products requires that the absorbent material be insulated both externally and internally. Exterior to prevent the diaper or liner from leaking into the environment, and inward to prevent the wearer's skin from coming into contact with wet material. Such insulation can be achieved by encapsulating the wicking material with an impermeable film layer on the outside and a liquid-impermeable covering on the skin-facing surface, which always produces a dry feeling.

The use of diapers and sanitary napkins generates a great deal of waste, which is difficult to handle. These products are too large to be flushed in the toilet and do not fit very well with ordinary garbage bags, such as those used for the storage and disposal of household waste. If solid corpse

- Being transported with 5 dacians, the capacity of the waste disposal plants used is tied up with bulk materials that can be handled in a simpler way: waste from pure organic materials can also be composted.

U.S. Pat. No. 2,826,199 discloses a diaper having an outer layer of a liquid impermeable material and an inner layer of a terry cloth of flannel fabric having small holes in the center. Starting from the front edge of the diaper, there is a pocket opening between the two layers. The pocket contains a foam pad that can be reused after drying. Of course, this solution is inadequate.

A 5,070 O95. s. U.S. Pat. No. 5,123,011 discloses a multilayer material which can be used to make suitable absorbent articles or such products. The skin-contact layer of this multilayer material is a thin, loose and soft liquid-absorbent cellulosic material coated on at least one side with a moisture impermeable material, the application of which does not preclude removal of the product from the toilet shells after use. . The inner sides of the product are impregnated with highly absorbent material which is also degradable. These products are very unsuitable for this purpose because, in order to be rinsed with water, they can only have very low strength when wet, so they are more or less disintegrated during use. However, if these products are made to be of practicable quality, especially if they are of a larger size, they cannot be flushed with water in the toilet,

Because there is no appropriate recommended method to ensure flushing.

Following such precedents, the present invention is directed to the manufacture of products of a design which, when used, provide the ability to readily separate the wicking material from the surrounding casing. Thus, the casing material can be treated as a relatively small amount of solid waste, while the bulk biodegradable absorbent material, which is a large portion of the product volume, is simply disposed of by dropping it into the toilet bowl and rinsing with water. For example, they may be constructed of inserts which are composed of two or more parts, or which may be easily separated into two or more smaller parts and disposed of as waste.

In the case of sanitary napkins, the invention may be implemented by providing the cover material surrounding the cover material with a Velcro closure which allows the cover to be ruptured and the cushion or individual cushion parts contained therein to be easily separated. so the user can easily separate the trash that can be disposed of with household garbage from one or, preferably, several smaller liners that can be removed immediately in the toilet ·

For diapers, the situation is a bit different, since the diaper is not a pillow or a pad. Diapers are complete clothing items that, in addition to the absorbent pad, also have a garment that can be attached to the baby's body. The disposable (disposable) diapers in question are characterized in that the garment is made of absorbent material.

- It is made with an attachment attached to the foil surrounding the 5 l cushion. A particular advantage of the present invention is that the cushion and the cover are separable so that the materials of these two parts can be handled optimally.

It is particularly advantageous, particularly in the case of diapers, to design the cover or garment in accordance with the present invention, in accordance with the foregoing and in accordance with the present invention, using washable fabrics. It is very advantageous to make the cover and the garment out of cotton or properly washable, skin-friendly material. Thus, diapers consisting of a reusable cover or garment and a disposable (disposable) absorbent pad or pad are placed on the market.

A significant advantage in waste management is that most of the weight of a diaper - that is, the cover or garment - becomes waste only after repeated use. Given that the pillow absorption is provided by the pads, said fabrics do not need to be sized as if they were also absorbent, i.e. they were not designed to be bulky. Thus, these fabrics can be easily washed in household washing machines, even with other garments, without the heavy load of the machines. Thus, without a noticeable increase in treatment costs, the actual amount of waste is minimized, while the situation of disposable diapers is much more convenient.

Contaminants, especially those in diapers, may contain not only liquids but also faeces. These materials are first and foremost the cheapest waste management salary • · ·

it is advisable to dispose of it in waste water, ie flush it with water into the waste water stream. There is no difficulty in separating the pollutant into smaller units in order to be rinsed with water. To this end, the excrement may be applied directly to the exterior surfaces of the absorbent pad portions provided that they are previously suitable for rinsing with water.

However, it should be noted that one of the advantages of the present invention is that the wrapper or garment is provided with an inwardly pocket or flap (hanging fabric) made of a fluid-permeable and non-absorbent fabric that permanently keeps the skin and skin dry. proper separation between the absorber. Without this flap, the outside of the pad or cushion would have to be covered with such an outer fabric coating. Thus, the present invention enables the production of cheaper pad pads, since there is no need to provide the pad pads themselves with such textile borite. The feces is deposited directly on said flap, from where the user can easily fold or shake the toilet after unfolding the diaper and dispose of the pad or pads in the same manner.

The cushion portion can be preformed so that it looks like a piece of the right size, but in fact it is made up of several interrelated pieces that can easily be separated: they are already separated by the action of the rinse water. thus, the user can treat the pad portion as a continuous, relatively large piece when inserting it into the garment cover and later removing

- 7 from the fact that the pillow automatically separates into smaller pieces that do not cause any difficulty when passing through the sewage system ·

Said flap can optionally be made so that one end is sewn onto the piece of fabric and the other end is provided with a Velcro strap.

Current diaper inserts as small pieces can be manufactured relatively inexpensively, so they are not difficult to manufacture or store, even if they are made to different designs. Depending on the size of the pads, the size of the pads, their absorbency, and whether they are made for girls or boys. In this regard, it is important to note that pads with different absorption capacities may be used according to the daily rhythm of the children, since some diaper changing pads have a lower absorbency capacity compared to the high absorbent pads commonly used at night. It should be noted that any unused capacity, such as during the daytime hours, would burden the total waste used in the treatment of the waste, but it was also necessary to produce an amount of wood pulp corresponding to this waste mass. Of course, in the practice of the present invention, diaper covers of the same size can be used for pads of different absorption capacities.

According to a preferred embodiment of the invention, said flap is made to oversize so that it can be packaged in a realistic manner, which, when properly stabilized, can be made of low-coherent material to ensure rinsing with water. The juice

- 8 suction pads can be a completely loose, non-binder fiber bundle or paper coated package.

The invention will now be described in more detail with reference to the drawings, of which:

Figures 7 and 8 are sectional views of the cushion pad for the diaper of Figure 5; and

Fig. 9 and Fig. 10 show, respectively, the insert according to the invention in perspective and from the end.

The diaper shown in Figure 1 includes an outer wrapper or garment part 2 made of cotton or some other suitable textile material. This cloth itself is not an absorbent part of the diaper, so that the wrapper 2 can be made of a very lightweight material, preferably two textile layers 4. and an intermediate layer 6 made of a liquid impermeable material therebetween. The intermediate layer 6 does not fully reach the edge of the casing. Instead of pure cotton, the cover - for easy washing and drying - can be made up to 60% pa, for example

- a blend of 9 prints and 40% polyester; thus, the product also has a longer service life. In fact, the diaper content can be even greater, since this part of the diaper does not need to be absorbent at all and modern synthetic materials can be made in a quality that is very soft and comfortable. The figure does not show that the cover can be provided with special closures, such as Velcro fasteners, or it can be made in other ways when manufacturing high-quality products, such as with integrated rubber bands at the edges and at the side snaps. It is acceptable that if the product of the invention is much more expensive than a disposable diaper because it is hundreds of times usable and even more comfortable ·

In the tight-fitting portions around the legs and waist, the cover must be provided with a comfortable breathable textile contact layer, since the layer 6 does not reach the edge of the cover, although otherwise this layer prevents the fluid from contacting the skin layer. In this regard, it should be noted that it is not even necessary to maintain some distance between the layer 6 and the edge of the cover, since the skin will otherwise be in contact with the breathable textile layer. In fact, it is possible to prevent the skin from touching the outer edges of the layer 6 by performing a seam welding on the outwardly folded edge fold of the workpiece.

At the inner side of the cover 2, the textile valve 10 is sewn-fastened in place 8 and is made of a liquid-permeable, non-absorbent material, for example one of the materials commonly used on the inside of disposable diapers,

if any, of even better quality - made. This flap covers the entire critical surface and is designed to cover the 12 diaper pads beneath it. The free end of the flap can optionally be adapted to be releasably attached to the cover 2, for example by means of a velcro fastener.

As mentioned above, diaper pads can be manufactured in a variety of designs that differ in size according to their absorbency or are intended for girls or boys. Pillows or pads can be made of fibrous materials without any wrapping, if necessary, by simply increasing the concentration of the binding fibers on the flat sides and adjusting the amount of superabsorbent, i.e., material with a high absorbency capacity.

The cushions at the edges can be closed by welding or by any other means. In addition to the pillows, there may be some glue sticks that hold the pads in position after they are attached.

It is possible to use cushions that fit into the waste treatment or decommissioning equipment into which the used cushions are, for example, incinerated, directly composted or indirectly composted from the sewage system after the toilet has been removed. Larger cushions generally cannot be rinsed directly with water, but the cushions of the present invention may consist of two or more pieces that are easily separated after removal of the cover, for example because the contact between the contact surfaces in the wet environment is

weakened before exception. Rinsing with water is a convenient solution, and since users are generally aware that the entire pillow can clog the drain, they are interested in taking the little effort they need to separate them if they have properly made pillows. These pillows may also consist of separate pieces that are held together only by the adhesive tape so that the whole pillow is released together. In this case, the user only has to tear off this piece of adhesive tape to separate the individual parts of the cushion. The diaper cushion shown in Figure 2 shows the line 14 along which the pieces of the cushion separate.

The sanitary pad shown in Figure 5 has a suitable absorbent pad 12 surrounded by a casing consisting of a fluid impermeable outer layer and a non-absorbent fluid permeable inner layer. According to the invention, this cover is provided with a velcro closure 16 which allows the user to drop the used pillow into the toilet by simply opening the cover and treating the cover as solid waste. Alternatively, one side is made up of two pieces and these pieces are held together by a removable adhesive tape.

It is also possible to make ordinary disposable diapers as described above with a water-removable pad. In this case, only the remainder of the diaper usually reproduces household trash.

Fig. 4 shows a diaper cloth or cover according to Fig. 1, in which only the flap 10 is sewn or otherwise fastened to the diaper main body, namely three pieces. This results in an elongated pocket that can be reached from the back of the diaper so that it can be manually inserted and removed from the diaper 12 so that the cushion is completely protected inside the pocket, thus reducing its strength. demand. After all, a loose blend of cellulosic fibers and some highly absorbent material would be suitable, but it is advisable to use prefabricated fiber packages that are only wrapped in toilet-like paper so that they can be easily rinsed in the toilet after use. after we pulled them out or somehow pulled them out of the elongated pocket. Feces, if any, can be disposed of in the same way.

In the absence of stringent pillow strength requirements, these pillows are extremely easy to manufacture and can be easily rinsed with water into the sewage system. The pillows do not need to be wrapped in any strong material and, if appropriate, can be coated with a suitable binder to partially decompose while remaining in the diaper pocket as soon as they have become wet during use.

After use, the pillow can easily be squeezed out or cast from the diaper and easily beaten with a strong rinse jet. If desired, the pillow can also be treated as fully compostable solid waste, known as "green waste".

The length of the pillows is preferably less than half the length of the pocket. So the pillow is exactly the right «· ·

- It can be put in 13 places, whether girl or boy wears the diaper. It is also possible to put two overlapping pillows in your pocket during extremely productive periods, such as at night. Thus, the desirable use for different needs can be achieved using inexpensive standard ingredients. It is also possible for the pillows to have an even smaller surface area and thickness, to meet even more diverse needs.

In addition to the latch 10 of Fig. 1 and the pocket of Fig. 4, it is conceivable to form a plurality of latches or half-pockets of fluid-permeable material: for example, the latch of Fig. 4 is fastened with one of its long sides and fastened to the other long side and the front short side. This makes it easier to remove the cushion or pads you have inserted, even though they remain permanently in place during use. Even conventional disposable diapers are advantageously manufactured in one or the other embodiment, since in this case the dirt can be separated from the diaper cover.

A special embodiment of the diaper cover is shown in Figure 5. The fabric diaper of FIG. 1 is in this case completed with a sewn-on textile strip 20 which, in a known manner, raises a barrier from the middle production zone to the product which is intended to protrude laterally and rearward. This rain may be made of the same fluid-tight yet breathable material as the intermediate layer 6 of the casing. Attached to one side of this bar is a laterally extending flap portion 22 made of the same fluid-permeable and non-absorbent material as the

The valve 10 of FIG. As can be seen, the side edges 24 of the flap portion may be folded. The suction cups 12 may be inserted between the folds at the outer end of the flapper section and then inserted into the receiving duct with some folding of the flapper section, which, as shown in FIG. forms.

so the 12 pads are easy to install '. First of all, however, it should be noted that the cushion portion 22 effectively surrounds the cushion, which is easy to fold out of this position: the cover is simply tilted to the side, thereby unrolling the cushion from its fixed position. Preferably, it is transferred to the toilet, where it is removed by flushing.

Given that the cushion 12 in this case is particularly well protected in the folded flap portion 22 held inside the pocket 20, a correspondingly weakened cushion can be manufactured to be extremely disassembled when poured into the toilet.

The pads 12 shown in Figure 7 are made in the form of a fibrous sheet of absorbent material, which is wrapped in low-moisture paper, i.e. paper similar to toilet paper. The package 28 may be single or multiple around the fiber plate 26. The paper shown in Figure 7 is wrapped around the pillow one and a half times, so that there is a double layer of paper on one side of the pillow and only one layer on the sides. When the fluid uptake expands the fibrous sheet 26, the sheet becomes thicker at these lateral edges due to the thickening of the sheet and tears to such an extent that it no longer

- 15 • ·· capable of holding together a package of 26 fiber boards. The padding can thus be cast in a partially disassembled condition, and the remaining parts will simply disintegrate during rinsing with water.

As mentioned above with reference to Figure 5, the cushion may be provided with a Velcro fastener 16. This Velcro closure in this case allows the paper wrapping around the package of fiberboard 26 to be torn away, thereby ensuring that the entire pad 12 is easily rinsed. In this regard, it should be noted that feces, if any, can be introduced into the toilet before the treatment of the pillow case becomes timely, so that a simple lifting of the pillow will allow safe rinsing with water under clean conditions.

It is also possible to establish an operative connection between the cushion and the diaper or the flap 22 when attaching the cushion, for example by applying an adhesive zone. thus, the pillow will fall off as a result of heavy pouring, without any special treatment.

Figure 8 shows that two separate JO sheets or pads can be used instead of a fiber board 26. In principle, such a division can be accomplished both longitudinally and in the direction of the scissors, thereby ensuring from the outset that the cushions fall into relatively small pieces so that they can be rinsed with water without difficulty. This solution can make the manufacture more complicated, but even if the fiberboard is simply divided into two parts, either longitudinally or sawn, it will achieve good results.

Figure 9 shows that the pad 12 may also appear in the form of a properly sealed package in a wrapping paper 28 having a · ··

- 16 ends are sealed with J2 stamping. Therefore, this pillow can be completely rinsed with water in the toilet after use, in a more or less disassembled state.

In the context of the present invention, it has been discovered that when using simple 26 or JO fiber packages in which the material distribution, including its highly absorbent material, is uniform, it is advantageous to design the package in such a way that patchy fluid loads are easily distributed throughout the pad and the absorption capacity of the pillow can be fully utilized. Therefore, as shown in Figures 9 and 10, the cushion 12 may be formed with grooves J4 pressed on its surface, along which the liquid may be distributed over the entire surface of the cushion.

In this regard, it should be noted that further optimization with respect to the preceding paragraph is possible if a wrapping paper is used in which the orientation of the fibers facilitates the distribution of the liquid mainly in the longitudinal direction of the pad. In addition, it is also possible to select the fabric of the flap 22 as having a good fluid delivery capacity.

Even if the pillow is removed when not fully used, at least some of its surface is soaked that its paper wrap is weak enough to easily crack. Most users automatically make sure that a used pillow is at least partially cracked before being put in the toilet. Given that the fabric of the flap 22 is generally a deformable knit material, the user can easily tear the pillow by the external handling of the wrapping 22 or the entire associated portion of the diaper without the need for any special device.
