Definitions
- Disposable absorbent items are items that absorb and contain body exudates and are discarded after use, including disposable diapers and panties for babies and adults, female towels, protective panty, etc. Articles have become an indispensable part in the daily life of any family, therefore, an infinite number of technical proposals have been developed to improve them.
- a disposable absorbent article such as a diaper or a disposable brief, is basically formed by a liquid permeable inner layer, a liquid impervious outer layer and an absorbent matrix placed between both inner and outer layers; the elastic threads or leg bands are placed between the inner and outer layers, such that, during use, only the permeable inner layer is placed between the elastic threads or bands and the user's leg.
- the inner layer of such an article is generally a non-woven fabric of low base weight, so it is not a suitable insulator for that the elastic band or threads do not hurt the user's skin.
- the waterproof outer layer has a fabric appearance, for this reason a laminate of two layers joined together, a layer of a hydrophobic plastic film on the inner part is generally used as the outer layer of the laminate, and a layer of non-woven fabric on the outside, to achieve the appearance of fabric.
- the elastic band or threads that form the adjustment zone in the crotch of the article be placed between the two layers that form the laminate of the outer layer, thus between the elastic band or threads and the skin is a double layer of material that helps soften this area and isolate this elastic band or threads protecting the user's skin.
- the placement of the elastic band or threads between the layers of the laminate of the outer layer gives the possibility of extending the width of the elastic area of the waist of the article, since with the traditional placement, between the inner layers and external, it is necessary to create a channel without adhesive through the front and back of the article, which extends up and down to the transverse edges, from the elastic crotch area on each side of the absorbent die, in such a way that the elastic waist area is limited to the distance between these channels.
- the objective of the present invention is to achieve a suitable adjustment of a disposable absorbent article to the user's skin in the elastic crotch area, forming an efficient seal that does not harm the user's skin
- Another objective of the invention is that this solution is feasible, easy to apply and does not increase the cost of the product.
- a further objective of the invention is that it is possible to extend the width of the elastic waist area, either by the front and / or the back of the article.
- FIG. 1 A diaper of the prior art is shown in Figure 1
- Figure 2 illustrates the diaper of the invention
- FIG. 3 is a section along the line AA 'of Figure 2. Detailed description of the invention
- a disposable absorbent article is an article that absorbs and contains body exudates and is discarded after use. This description will be based on a disposable diaper for babies, it being understood that it can also be applied to other types of disposable absorbent articles, such as disposable diapers and protectors for incontinent adults, training briefs, female sanitary napkins and incontinence towels.
- Figures 1 and 2 show a disposable diaper formed by an inner layer (40) permeable to liquids, an outer layer (42) impervious to liquids, an absorbent matrix (44) placed between both inner (40) and outer layers ( 42), a fastening system formed by a pair of tape tabs (48) and a front band or tape (50);
- the diaper also has two elastic zones, one at the waist (64) and the other, on both longitudinal sides, at the crotch of the article, that is to say an elastic crotch zone (66).
- the inner (40) and outer (42) layers are cotermines and extend beyond the margins of the absorbent matrix (44), forming the diaper contour (46).
- Absorbent items such as diapers disposable, they have a front zone (58), a rear zone (60) and a crotch zone (62); the front area (58) is the one that will be placed by the front waist and hip part of the user during use, the rear area (60) will be placed by the rear waist and hip parts thereof, while the crotch area (62) is the one that will be placed between the legs and wrapping the user's thighs during use.
- a non-woven fabric of low base weight between 6 and 20 g / m 2 , is generally used; it can be hydrophilic or it can have a hydrophilic zone in the central part and two hydrophobic zones on each side of it.
- the non-woven fabric used as an inner layer (40) can have any composition (polyethylene, polypropylene, polyester, cotton, cellulose, rayon, polylactic acid, etc.) and can be formed by single component fibers, bi components, tri components or mixtures of this.
- the fibers that form the fabric can be joined using any known process in the medium, such as pressure and heat bonding through a calender, resin bonding, hot air bonding, etc. and can be composed of one or several layers joined together.
- the inner cover (54) of the laminate is hydrophobic and the outer one (56) can be hydrophilic or hydrophobic.
- a low density polyethylene is used as internal cover (54); a hydrophobic nonwoven fabric can also be used.
- an outer cover (56) a non-woven fabric is used.
- the inner cover (54) of the laminate will be placed inside the article and prevent the passage of body fluids.
- the non-woven fabric of the outer cover (56), will give the fabric-like appearance to the article; This non-woven fabric gives the view and appearance outside the article, it can be engraved or printed with various graphics to make the article attractive; Any type of non-woven fabric such as those described for the inner layer (40) can be used, provided it has the appropriate mechanical characteristics to be laminated with the hydrophobic layer, as well as the softness, flexibility and appearance required. It can be hydrophilic or hydrophobic.
- the absorbent matrix (44) of the article of the invention may consist of fibers of absorbent material, such as defibrated cellulose, as well as any other type of natural or synthetic absorbent fibers such as polyester, polypropylene, rayon, etc.
- the fibers of absorbent material may be mixed with superabsorbent, synthetic or natural material, such as polyacrylates, starches, alginates, chitosan, etc.
- Figure 1 shows an absorbent matrix (44) in the form of "I", however it can have other shapes, it can be rectangular, hourglass shaped, "T” shaped or any other shape that is consider appropriate.
- the article fastening system is formed by a pair of tape tabs (48) and a front band or tape (50).
- the tape tabs (48) generally are attached to the rear waist part of the article, or, as shown in Figure 2, to a pair of ears (52) that can be rigid or elastic and which, in turn, are attached to the rear area (60) of the article; the tape tabs (48) may have areas or be completely rigid or elastic, may be adhesive or mechanical; the front band or tape (50) is placed on the outer layer (42) by the front waist part of the article, and must be chosen from a suitable material, so that the tape tabs (48) can be detachable from it , such that they can be separated and rejoined as many Sometimes it is necessary to adjust the article when placed in the user and they can be detached without tearing or hurting the article when the article is removed from the user.
- the elastic crotch zones (66) are formed by the inclusion of elastic crotch threads or bands (68) in the crotch zone (62) of the diaper.
- these elastic threads or bands (68) are placed in tension between the inner (40) and outer (42) layers, as shown in Figure 1.
- the elastic band or threads (68) interposes only the non-woven fabric layer from which the inner layer (40) of the article is formed.
- this non-woven fabric be of low base weight, between 6 and 20 gr / m 2 .
- the elastic crotch threads or bands are placed between the layers forming the laminate of the outer layer (42) of the article, as shown in Figures 2 and 3 such that between the The user's skin and the elastic band or threads interpose the inner cover (54) of the laminate (42) and the non-woven fabric of the inner layer of the article (40), insulating the elastic band or threads (68) to protect the user's skin.
- the disposable absorbent articles are manufactured in continuous production lines that work at high speeds, to place the elastic crotch bands or threads, these are stretched to the desired tension, and are joined between the desired layers of the article, while it is advancing in The manufacturing line.
- an intermittent application of adhesive is generally made in the area where it is desired that the elastic band or threads remain active;
- the application of adhesive can be done on any of the layers between which the elastic threads or bands will be placed or on both; in this way, the elastic band or threads (68) are tensioned to the desired substrate in the crotch area (62).
- a channel without adhesive (72) is created in the areas above and below the active zone of the elastics (74), that is, From the area where the adhesive is applied, this non-adhesive channel extends to the front and rear transverse edges of the article.
- the elastic waist area (48) is seen limited to the width between these channels without adhesive (74), as can be seen in Figure 1 (prior art), since if the elastic threads or waistbands (46) are placed on these channels (74), it is necessary Apply adhesive in this area and elastic crotch threads or bands (68) will be fixed tensioned in the waist area deforming the diaper.
- the adhesive-free channel is formed between these layers and the area Elastic waist (64) can be extended to the total width of the rear waist part of the article, as shown in Figure 2, which shows the diaper of the invention, since the elastic waist area adhesive is placed between the permeable inner layer (40) and the inner part of the impermeable cover (54) of the laminate that forms the outer layer (42) of the article, and in this way the adhesive does not come into contact with the channel without adhesive (72) that in this case it is created between the inner (54) and outer (56) covers of the east laminate.
- the laminate used as the outer layer (42) can be purchased as such (already laminated) and enter the line of production of the disposable absorbent article as a single material or it can be formed as an additional process within the manufacturing line of the article.
- the production line has an additional module to form the laminate; the non-woven fabric (56) (external laminate cover) and the hydrophobic layer (54) (internal laminate cover), are fed to this module and joined as another step of the article manufacturing process, to this known as online laminate.
- the joint between the covers that form the laminate can be done by thermal, adhesive, ultrasonic or any other type of joint known in the middle.
- the laminate that forms the outer layer (42) must be formed in a line, such that it is possible to introduce the elastic threads or bands between the legs (68) between the layers that form the laminate.
