Single use paper diaper .

The present invention relates to paper diapers for single use, which are then thrown away «

There are currently “two types of τοη diapers for the one-time Use, namely rectangular or cut to body shape diapers. The rectangular diaper offers certain advantages, since it can be manufactured in an economical manner as well as being a product that has a considerable amount of money Abaorptiven area in the file of the diaper that is unbuckled. However, the amount of material in the folded part makes swaddling the child with a rectangular diaper difficult and quite inconvenient and cumbersome to use. Sa the diaper is only put on briefly in most cases, the absorbent material in the insole is also sold not used in the best possible way. Also enables her Spread your legs, slide the diaper down so that

90S607 / Ö204

it can hang down from the trunk of the body. Hence the effek tive absorption capacity is much lower than one because of the Amount of absorbent material used in the diaper.

The type of single-use diaper tailored to the body shape is in the shape of an hourglass, making it easy to put on and practical to use. This shape sets the possibility of legs, the diaper from Pushing away torso to a minimum «On the other hand, the manufacture of this type of diaper is normal because of waste and others problems encountered in the manufacture of an object with irregular lines Furthermore, since part of the absorbent material in the

Training of the body shape adapted envelope part cut away is, both the absorptive area and the absorption capacity of the diaper are significantly reduced.

Both of the currently used types of diapers described above have other disadvantages in common. For example lead such diapers when they are put on a child without the protection of waterproof pants surrounding them to a high degree of leakage, seepage and / or penetration of the excretions into the child's clothing, thereby reducing the clothing becomes soiled, unpleasant odors occur, the items of clothing become uncomfortable to wear and they are washed have to. This is the case even though some of these diapers are provided with a waterproof outer skin in order to to protect the clothing against such soiling.

Another common disadvantage of the diapers described above is that the absorptive material tend to stick together. This is undesirable for two reasons (1) It significantly degrades absorbency compared to its initial capacity, and (2) decreases the surface area that is available for the absorption of the liquid, so that the rate at which the absorption can take place, is limited, creating another

909807/0204

Leakage is favored during the extended period of time required for the liquid to be absorbed.

Another disadvantage of these products is that they often stick to the skin after removing the diaper paper particles adhering to the child can be found. This is very inconvenient for those who change the diaper, since the particles τοη must be wiped off or wiped off the child, and the fact that the diaper is so SerrLleben gives the impression that it is unsuitable to fulfill the function su because of which it was bought became.

The subject of the present invention is a diaper for single use with sufficient absorption, which can easily be put on a child, has an appealing appearance, when used «is wake up, the clothing against soiling through leakage, Leakage and penetration pours, produced in an economical way «earth and its absorbent part in a toilet can be washed away.

Such a diaper according to the invention for the one-time Use consists of a thin flexible back made of waterproof material which is attached to a liner made of absorbent material, the back and the liner, which are connected to one another, in a number of Longitudinal folds are folded in such a way that the opposite -den tapes come flat, against each other su and where the Bückaelte has opposing rare tabs that overlap the larger upper areas of the fold.

Zn Pi £. 1 there is shown an embodiment of a diaper having an absorbent rectangular pad 21 which is arranged substantially in the middle of a flexible back made of waterproof material, such as polyethylene, which is longer and wider than the corresponding dimensions of the liner 21 insert 21 and the rear side are connected to each other, for example by gluing the calibration contacting surfaces along the regions 23 and 24 located in the IAHE of extending in iÄngerichtung Sander the input Λ 21, au prevent accidental would read and the location of the two parts to each other.

In the preferred embodiment shown in FIG. 2, the insert 21 consists of a plurality of layers of folded, creped cellulose wadding, which are surrounded on one side and on all four bands by an upper or inner loop made of porous, hydrophobic, non-woven material is. The top 26 is preferably glued to the underside of the layers of cellulose wadding 25 and to their overlapping parts along the longitudinal areas 27 and 28 and the laterally extending areas 27 * and 28 * of the ends and sides 29 of the top layer 26 λ , which lead under the wadding 25 and limit the bottom. The adhesive applied to the areas 27 »27 * , 28 and 28 * is, if at all, preferably only slowly soluble in water, so that the risk of the top layer 26 becoming detached from the absorbent wadding 25 during use is eliminated. One adhesive that has been found useful is a latex whitened polyethylene adhesive sold, for example, by United Shoe Machinery Corporation and designated Therraogrip # 307. The areas 27 and 28 are continuously connected to the curved side edges of the top layer 26, so that they the adjacent areas of the top layer 26 and the

909807 / 020A

Cellulose wadding 25 from the side edge of the unit consisting of the connected parts inwards for one separate from each other as described below.

The course of the machine-pressed folds of the creped cellulose wadding is preferably aligned so that the machine direction of the folds is transverse to the length of the diaper. The arrangement is at a diaper according to the type of the present invention increases the effective capacity compared to inserts in which the machine direction of the folds in the longitudinal direction to the wadding 25 extending substantially in the longitudinal direction of the diaper. This fact is described in more detail below.

Although the amount of wadding to be used in a diaper of this type can be varied depending on the desired performance and cost issues, it has been found advantageous to use wadding that consists of ten layers and a base weight (air dry) 210 his prior to creping 245 g / nt ² has. In order to fully utilize the advantages of the course of the sewing direction of the crepe folds transversely to the length of the diaper, the folds of the wadding 25 should have a crepe of 60 ° C. or very, the percentage crepe being equal to 100 times the quotient of the reduction in length caused by creping a layer of cotton wool divided by the length of the uncreped cotton swab. The wadding 25 is the regulating factor in determining the thickness of the inserts 21 because the inserts 21 are essentially the same in terms of their dimensions. A cotton swab 25 »which can easily be flushed away in a toilet and which has sufficient capacity for diaper purposes, preferably has a weight of about 25 g and is about 31 * 75 cm wide and 40.64 cm long.

The topsheet 26 can be any useful soft, porous, hydrophobic paper or nonwoven material. An example of the layer made of non-woven material that is used in the

diapers according to the invention, consists of a rayon with 1.5 to 3 denier and contains about 20 to 35 1 thentoplaetic binding material (for example the copolymers of an ester of acrylic acid, which is available, for example, from Rohm * Haas Co. under the Designation B-15 is sold) and has a weight of about 17.9 to 22.7 g / m To achieve optimal results, surface-active agents should only be drawn in minimal quantities in the binding material emulsion in the production of such a material and completely avoided in the final bath. If the watt · 25 has the above dimensions (31 »75 whether wide, 40.64 cm long), an · economical · and easily passande upper class can be 36.83 om wide and 45» 72 cm long _ •• in. *

The flexible, waterproof back 22 is preferably made of an opaque polyethylene with a thickness of 0.254 mm low density, preferably by about 2.54 to 7.62 cm longer and about 5.08 to about IU, 16 cm wider than dl corresponding dimensions of the insert 21. With such a dimension, files of the rear side 22 extend over dl · perimetric limit of the insert 21 and run in opposite end strelfen 30 and side strips or Tabs 31. Oute results were obtained with Endstrelfen 30 achieved, which are about 2.54 cm wide and with side flaps 31, which are preferably each about 3 * 31 to 4.45 em wide. With these dimensions, when using | neither slip out of their actual position nor they reach so far in that they adversely affect the function of the diaper as a whole. The purpose and function of the end strips 30 and rare tabs 31 go beyond the explanation following the description of the diaper of the present invention.

As has already been indicated, the insert 21 and the rear side 22 are against one another along the regions 25 and 24 glued. However, it is not desirable to wash away the waterproof back 22 together with the insert 21 in a C. Saher should be the bond between the insert 21 and the back 22 is very tear-resistant, but it is made in this way

be »that the interlining insert and back side easily separated by peeling off one τοη the other can be. Is the glue that was used and as an example when gluing the insert 21 and the back side 22 is a plasticizer-containing polyethylene adhesive such as the sold by National Starch and Chemical Corporation and designated National Starch Resyn No, 34-3 · ΟΟΟ Adhesive. This adhesive is applied to the insert as a 3 mm wide strip at about 121 ° and quickly cooled to a temperature of about 38 to 60 ° »« and what Time presses the insert and the back side together will. After bonding, the adhesive solidifies in less than 2 seconds.

As is explained in FIGS. 1, 2, 4 and 5, a fastener, such as an adhesive strip 32, can be provided on the side of the rear side 22 in addition to the strips connected to the insert. The fasteners 32 each consist of an adhesive strip which is divided into two areas 32a and 32b, each of which extends the full length of the strip. Area 32b has a pull tab 32c which overlies and is held by the adhesive film on that area, the tab having an easily grippable free end which extends outward and is formed by pulling tab 32c down upon itself their longitudinal axis is repulsed. The fasteners 32 are located on the underside of the back 22, one at a time, on a side flap 31 near an upper corner of the insert 21 (as shown in FIG. 1) and are adhered to area 32a of each fastener by the adhesive.

The diaper shown in Fig. 1, assembled from the individual components, is longitudinally along fold lines 33, 34, 35 and 36, and thereby the insert 21 and the underlying parts of the rear side 22 are divided into five areas A, B, C, D and E.

mm Q _

Area C is in the cement and makes up about one third of the width of insert 21, while areas A, B, B and JS are about the same and each have a width of about one sixth of the transverse dimension of insert 21. Areas A and B are adjacent to one another and are connected to one edge of area C, and areas D and £ are equally adjacent to one another and are connected to the other edge of area C. The two outer areas Jl and S of the five fields each extend into one of the lateral edge strips or tabs 31.

Immediately before splitting along lines 33 to 36 will put a blob 37 of glue on the side axis of the Areas B and D applied in places that preferably «wipe about one tenth and about 5/8 of the width of the Areas away from the fold lines 33 and 37, respectively. Such a glue blob could also be in the area C at places are applied, which are arranged at a distance from each other that they xu sticking together with the areas B and guide D at the locations described above when the diaper is folded. The primary function of the blobs is to keep the turned-up diaper area in its folded position at least until the Child the diaper was put on. After that, the effect is useful, but not essential for maintaining the structure. Other means (e.g. staples, seams, etc.) could be used in performing this function, the blobs 37 being preferred. One adhesive that is suitable for this purpose is an old polyethylene adhesive of a plasticizer, as already mentioned with regard to sticking together the insert 21 with the back 22 was described.

The diaper is initially, as in Flg. 3 shown molded the fold areas B and D extending inwardly along fold lines 34 and 35 respectively so that the portions of the top surface 26 of these areas coaaen in contact with area C, and the blob of adhesive 37, the parts of the upper side 26 »which are immediately below and above each blob

folds lie and the fold areas A and E glue together outwardly along lines 33 and 36, respectively, whereby the areas A and B with the stoop to each other and are arranged side by side so that they are in the same way how the areas D and E lie. After such splitting, the various areas are of this embodiment the diaper folded flat, the diaper through the blobs of adhesive 37 is held in place. The folds lying since lines 33 and 36 run in the substantially parallel to and adjacent to the longitudinal axis of the diaper and preferably at a distance of about 3 be arranged up to about 12 mm.

Each of the side flaps 31 is folded inwardly over the portion of the top layer 26 on area A or E, from which it as shown in Fig. 4 protrudes. The diaper can now be packaged and put on the market will. The folded structure allows convenient packaging as a compact unit, with the V / indel only is folded sideways along the middle of the diaper, whereas the diapers available so far are packed unfolded became.

In their use, the diaper is placed on the surface on which the baby is to be placed and one end is pulled apart. The ends of the outer regions A and E (which extend along the edge of the diaper and which have fastenings 32) which come to lie under the hip are gripped and in opposite directions Pulled sideways outward direction so that the diaper is pulled apart at the edge, with the ones on it Side flaps 31 maintain their position as shown in FIG. 5 with respect to areas A and E. The child is then placed on the part of the diaper that will lie under the hips, with the thighs tucked sideways into the Center and at a slight distance from the longitudinal one Center line should be placed in the direction of the curved end. In this position, the other end of the The diaper goes down and lies behind the baby's legs.

909807 / 020A

Then the lower end of the diaper is brought into a position to blend up the child's legs which it came to lie close to the torso of the child, and this end is then spread out in the same way as it is for sale with the one below the hip was made. The last steps will make the The central area of the diaper is slightly bent, with the adhesive blobs 37 forming the folded structure in this area maintained. The diaper is then attached to the child in that the corners of the waist part, which is the stomach covered as far around the child's waist as possible and the corners of the part underneath with the above-mentioned seken into an overlapping position, ^ so that the diaper softly surrounds the child's hips. The overlapping corners are secured in this position by safety pins or by means of the adhesive tape fastener 32 held. In the latter case, the corners are manually in the Held position and the Abiehlaschen 32b touched and removed from their connection with tape 32a and the tape 32a is equilaterally associated with the corners below, and swar in exactly the same way, how duct tape is put over a wound. Sowing the diaper was put on the child, it takes on the sloping shape in ELg.6.

As a result of the in the middle part of the diaper at the *

Use retained fold to fit the entire folded part (including the side edges of the diaper) closer to the child's torso than would be possible if the diaper were to be put on in a straight rectangular shape. This tightness is extremely important as it not only improves the appearance but also the effectiveness of the product is favorably influenced. It is true that inwardly curved, waterproof strips, such as s.B. the flaps 31 are also suitable in connection with many other diaper shapes, preventing dripping and seeping through directly from the insert; the functions of the invention Laschen, however, has been substantially expanded by the fact that one (susätslich see the preceding Sohuts against drops and leakage) a protection against passing

After the diaper has been put on the child, cause the folded construction of the diaper and the natural movements of the child that the folded area the diaper in the middle part, like in Pig. 6 shown is bent. In this state, the margins of the Fold in the folded area bent slightly downwards,. so that the corresponding side flaps 31 in this Assume a position in which they are close to the inner, rear and front area of the thighs aa Put on the child's torso. In this position, the tabs are effective against soaking through the diaper or set this down to a minimum and give the absorbent material within the diaper sufficient time, the liquid To absorb excretions and thus the ability to absorb to use the diaper as much as possible and at the same time prevent the clothing from being used, dl comes into contact with the baby. Since the diaper fora is originally rectangular, the absorption area becomes a maximum and the absorbent material is most economically maintained in the turned-up area, as is the case with diapers Desirable for single use is important when the diaper is provided with an effective containment material the liquids that the diaper is supposed to absorb * is provided.

As described above, when the diaper is bent in the turned-up part, the folds become along lines 33 and 36 in and from the folded area the area C below and form, as in Flg. 11, an open channel 40 is shown between the Parts B, C and D in the folded area and further the open pockets 41 and 42 in the transverse regions of the diaper between the folded area and the completely unfolded area extending from the folded portion at each end the diaper extends.

Baader of the diaper also lead and serve mle receiving containers and prevent the undesired spreading τοη solid waste in other areas of the diaper. This is mainly due to the structure and customization of the Diaper in the curved area and the improved absorbency of the combination consisting of folds and flaps.

As already mentioned above, it is τοη decided part of the gate, the layers of cellulose wadding 25 so au orient »that the MaBOhinenriohtung the crepe wrinkles runs across the length of the diaper. In this position, the grooves of the crepe la are essentially parallel the length of the diaper. It is a fact that moisture absorbed by a sheet of uncreped paper becomes "old in all directions on the leaf is absorbed at essentially the same speed" * .B. an applied drop of water wets a substantial amount of water circular area of the paper. However, a droplet of water falls onto the surface of a creped paper was applied, not su a moist area old essentially circular shape in plan view, but au a wetted area which is essentially in the shape of an ellipse. Me main axis of the ellipse is parallel see the grooves of the crepe or, in other words, perpendicular to the machine reddening of the sheet. If the creped paper When stretched to an uncreped condition, it will of course be found that the moist area of this creped sheet is also substantially circular.

From this it can be seen that if there is any advantage from the run of the deposit, the crepe lines are generally affected will be obtained, this will be at most insignificant appears. Keeping all other factors equal, in a given cellulose wadding area in an absorbent diaper it is generally of no consequence in which Machine alignment calibrates the wadding because the suction capacity remains the same. So it seems • Be a controversial question about whether the area turned over

909807/0204 ^BAD ORIGINAL

the diaper has the grooves of the crepe in the longitudinal or transverse direction su the diaper according to the invention, since the absorption capacity is approximately the same in both cases.

It is clear that the rapidity with which the child sheds the excretions when urinating is a factor the only advantage resulting from the sighting of the insert in the prevention of lateral seepage has an inflow. This is particularly true in the case of a conventional diaper, in which only waterproof side flaps are used to prevent dripping or leakage at the side edges of the diaper and »regardless of the direction of the creping, promote a longitudinal flow of the unsaturated parts of the diaper.

Regardless of what has been said about other diaper shapes, the creped cellulose wadding is the Diaper according to the invention, i.e. a diaper which has the fold described above, in which the direction of the crepe folds is essentially transverse to the Length of the diaper runs, found that a substantial improvement in actual absorbency when compared SU diapers occurs with the same fold where the machine direction of the batting extends lengthways The actual absorbency of a diaper can be viewed in terms of the ability of the diaper put on a child the absorption of liquid without detrimental wetting of clothing, the bed, the bed covers of the child, etc. To be defined.

Although the reasons for the improvement in the actual absorbency are not fully explained It is believed that the main factor is the stresses in use placed on the creped folds of the Diaper are exercised and which are larger in the transverse direction sur the diaper length than in the longitudinal direction of the diaper. By the fact that the meander direction of the folds on the

909807/0204 ^BAD

erecting greater tensions, the greater strength of the folds in the machine direction plus that goes through the creping obtained yielding the insert 21 more tear-resistant and therefore leads to fewer cracks. Thus, by preventing the insert 21 from tearing, the actual absorbency can surprisingly be improved. The improvement appears to be in the reduction of the agglomeration the cotton wool, an effect produced by the tearing or tearing of the crepe folds. Prepare as above was carried out, the agglomeration of the cellulose wadding significantly reduces the absorbency of the diaper and reduces the surface area of the batting, thereby significantly limiting the rate at which further absorption can take place. As a result, the ™ new diaper arrangement their absorbency and the absorption speed of the cellulose wadding more effectively than other diaper arrangements (using liners that are arranged differently).

The arrangement of the insert 21 in a catfish, at The machine direction of the folds 25 of the batting being transverse to the length also provides a means of reducing the peeling of the folds 25 which, in conventional diapers, tend to adhere to the child's skin. Such disintegration occurs particularly wherever the sides of the insert 21 not by parts of an overlying area pushed underneath, as in the case of f above described invention, surrounded and

E * was found that the Seitenetreifen are particularly desirable in the present invention diapers as diapers old a relatively high actual absorption capacity saturate another area of the diaper so that the leakage of the wound around the ^one waist portions of the diaper to clothing, the Touching the diaper in this area is more possible. In the case of side tires of the preferred width of about 2.5 ei, simple protection is provided in an economical manner against this form of sagging, without the expediency or the appearance being impaired.

After detaching, the insert becomes Submerged several times in the water of the toilet bowl, until a larger part of the crepe of the creped cellulose wadding dissolved 1st and floating loosely in the water. Then the toilet is flushed through (while using the remaining part of the insert still holds) until most of the dissolved material has been washed away. Then the remaining part can be thrown into the water for the same purpose.

It is therefore advantageous if the back side 22 can be pulled off the insert 21, if the glue pits 27 and 28 outside the glue pits 23 and 24 would lie, the folded side edges of the upper layer 26, which essentially "

nit the Ausführungsfora of Figures 1-6 described parts are identical, denoted by corresponding reference numerals and not explained further. As shown, »has this embodiment in the pitter part across the insert 21 an absorbent intermediate layer 38 made of creped cellulose wadding. The intermediate layer 38 can be inserted between the layers of the wadding 15 and the Mschinenriehtung its creping - Runs across the length of the diaper. The purpose of the intermediate sheet is to provide additional absorbent material Material in the most critical zone, namely the folded area of the diaper, so that further protection is given if the diaper is to be used for a longer period of time or if the child's urine output is abnormal is great. The additional material consisting of the intermediate layer 38 increases the absorbency of the diaper, however the area for receiving the liquid remains essentially same and the above-mentioned advantage of increasing the suction capacity through the folds and side flaps and the pleat and liner orientation of the present invention is made even more complete with the spacer 38 exploited

The modification of Figures 7-10 also sees the attachment of the sides of the inwardly folded edges of the side flaps 31 in a position above the surface of the insert 21. This is achieved by the blobs 39 of glue which are provided at each end of the outermost regions A and E at positions that are penetrated by the tabs 31 to be covered. It is important that the flaps 31 are fastened in the folded area so that they fulfill their actual function as described above can. The adhesive blobs 39 can be of the same type as those in the areas 23 and 24 for fastening the insert 21 and the back 22 used; however, it has been found to be entirely satisfactory is such a product from the company ölyco Chemicals, a »branch of Piram Charles L.
