Sanitary napkin with liquid-impermeable side wings or comparable

The present invention relates to a sanitary napkin or the like forming a sanitary napkin or the like, provided with liquid-impermeable side wings of sufficient size so that they can be turned around the undergarment worn by a person, these side wings being advantageously used after the ter-10 , for forming the disposable bag by folding, these side wings preferably forming a part substantially forming part of the protective bag.

EP 0 134 086 already discloses a sanitary napkin or the like, in particular for feminine hygiene, comprising a liquid-absorbent bandage element 216 placed completely inside a cover 214-230-234, of which at least the liquid-receiving part is liquid-permeable. . The side wings 224, 224 'are intended to improve tightness in the lateral direction 20 due to the fact that these side wings are placed inside the undergarment and their extremities are folded against the inner edge 246 or 246' of this undergarment.

It has been found that these side wings are insufficient in size to provide good protection for the entire undercarriage. These side wings may also comprise removable fastening members, such as stickers, to ensure removable attachment to the undergarment, as can be clearly seen (Figures 2, 4 and 7).

EP 0 130 848 discloses a solution of the same type, according to which, in addition, the side wings can also contain a liquid-absorbing bonding element on the inside.

The side wings are also described in FR 2,445,885. Another similar solution is disclosed in U.S. Pat. No. 4,285,343, with the side wings 2,800,22 turned outside the undergarment, completely covering it by overlapping (Fig. 2 or 5) or side by side (Fig. 7) and inside yet absorbent material.

U.S. Patent No. 4,608,047 further describes a sanitary napkin comprising side wings of sufficient size to pivot from the outside around a undergarment worn by a person, such as panties, at least one of these side wings comprising detachable wing attachments 34 on top of said undergarment 10, thereby providing complete protection of that underwear.

In addition, FR-A-2 494 226 discloses a structure for the individual packaging of hygiene products, such as sanitary napkins, before use, as well as a packaging method by means of this structure.

In addition, used sanitary napkins are generally thrown away in a disposable bag that is shipped separately with the bandages.

This creates ease of use and increases the cost of the finished-20.

It is therefore an object of the present invention to solve a technical problem by providing a solution which avoids the use of a separate cover for discarding the sanitary napkin after use.

It is a further object of the present invention to solve a technical problem by providing a solution for a sanitary napkin or comparable forming device which avoids the use of a single, separate, loose package.

These technical problems are preferably solved at the same time for the first time by the present invention, a particularly simple, inexpensive material which can be used on a factory scale.

Thus, the present invention relates in particular to a sanitary napkin or l; 3,8002, comprising a liquid-absorbent bandage element placed completely inside the cover, at least the liquid-receiving part of the cover being liquid-permeable, the side wings being designed to improve lateral tightness, said side wings being of sufficient size to be turned outside of a person's undergarment, such as panties, around these side wings comprising at least one member which allows said si-10 wings to be releasably attached to the undergarment, thus providing complete protection of said undergarment, said side wings being designed to form, after use of the sanitary napkin, by folding around the sanitary napkin itself. folded, a disposable package or bag characterized by a sanitary napkin that the side wings are formed to be liquid permeable a strip of non-woven material arranged on the sanitary napkin and the side wings being arranged so as to form an integral part of the protective bag in which the sanitary napkin is packed before use, the protective bag being provided on the other hand by sealing the side wings to the center of the strip edges perpendicular to the selvedges, on the other hand by grounding the side wings one on top of the other, parallel to said axis, and wherein the protective bag comprises means, in particular pre-cutting members, which allow the side wings to be released when the protective bag is opened.

The solution provided by the invention thus also makes it possible to obtain a tight bonding cover which ensures that the bonding element is protected against the ingress of dust and dirt before use. In addition, this cover is particularly economical, as it forms part of the bandage.

The above-mentioned cover, in which the liquid-absorbent banding element is placed, thus comprises on the outside at the front 4 and at the rear ends means for temporary connection with the underwear, the members of which are also intended to hold the sanitary napkin in an assembled position. The fastening members 5 of the wings are most preferably placed towards their outer edges, thus obtaining a cross-arrangement of the assembly of fastening and connecting members.

According to a particular embodiment, the attachment members of the side wings are placed on only one of the two si-wings of the wing, on the outer surface of the wing towards its free end, allowing to be fixed by superimposing the ends of the wings.

According to another particular embodiment, the wing attachment members are designed at the level of each end of the side wings 15 on the visible outer surface of the wings, protected from premature damage by detachable protection members which allow the protective bag to be formed either by stacking or side by side.

Removable guards against premature damage can form a silicone tape, as is well known.

Thus, it is found that all of the critical technical advantages described above are achieved, namely a unique sanitary napkin comprising side wings designed to form a package that is disposable after use, these side wings being further designed to form a bag that initially protects the sanitary napkin. Finally, these side wings also act as an additional attachment to the sanitary-30 bandage on the undergarment, fully protecting it during use.

Other objects, features and advantages of the invention will become more apparent from the following description, taken in conjunction with the accompanying drawings, which show various salts of a sanitary napkin according to the invention. 5 89002 ritual variants, which representation is given by way of illustration only and thus does not in any way limit the scope of the invention. In the drawing:

Fig. 8 shows a drawing similar to Fig. 7 of an embodiment; and Fig. 9 shows another drawing in a section similar to Figs. 7 and 8 of other embodiments.

Referring to Figure 1, there is shown a sanitary napkin or the like, particularly for feminine hygiene, with side wings.

This dressing is indicated by the continuous reference numeral 1 and comprises the actual dressing element by the reference numeral 2, which absorbs liquids, placed completely inside the cover 4, at least the liquid-receiving part 35 of the cover (opposite the part shown in Fig. 1) being liquid-permeable. Usually, the part opposite the liquid-receiving part of the cover, i.e. the part which attaches to the undergarment and which is the part shown in Figure 1, is either made of a liquid-impermeable material or is a liquid-permeable material, but in this case one liquid-impermeable layer (not shown here for simplicity). ) is placed between the tie element 2 and the part 4 of the cover which comes into contact with the undergarment.

The side element 2 may be pre-shaped, for example a general double-concave shape, as shown in Figure 1, which is well known in the field of sanitary napkins. Alternatively, the tie element may be pre-shaped to be clearly rectangular and terminate at the rear with a narrower portion 15, which is also generally known.

This means further comprises side wings 6, 8 extending transversely from the center of the tie element 2 and its cover 4. These side wings 6, 8 are of sufficient size so that they can be turned outwards around the undergarment worn by the person. They may also comprise detachable fastening means, referred to as 10, 12, respectively, which allow the side wings to be fastened to the outside of the undergarment, thus allowing complete protection of the undergarment.

These side wings 6, 8 are formed so as to form a disposable package 20, Figure 3 or bag, after the sanitary napkin has been used, by folding the side wings 6, 8 onto the sanitary napkin 2,4, which dressing 30 is also folded over itself.

This is further facilitated by the fact that in the example shown, the part of the cover 4 intended to come into contact with the undergarment, which part is the surface shown in Figure 1, comprises at its extremities 4a at the ends 4a and 35b at the rear for protection with the undergarment. for example, self-adhesive pieces 14, 16, respectively, by means of which the fastening members 10, 12 of the side wings 6, 8 are cross-arranged from the assembly of the fastening members 10, 12 and the connecting members 14, 16. In this cross arrangement, it is absolutely advantageous that it makes it possible to fold the sanitary napkin, i.e. the bandage element part 2 inside its cover 4, which covers it around, secures the bandage element 2 in the folded position thanks to the connecting members 10 14, 16 arranged at the front and rear ends. 4a, 4b, respectively. The side wings 6, 8 can then be easily folded over the tie element thus folded, so that a disposable package or bag 20 is obtained in the shape shown in Fig. 3. 15 Thus, with such a device, a separate package is no longer required for the proper disposal of a used sanitary napkin.

The members 10, 12 can be placed, as shown in Figures 1, 2, on the same side as the pieces 14, 16 for attaching the wings directly onto the undergarment after assembly. But they can be placed differently. For example, one of the two members may be on the opposite side to 12. The fastening is thus achieved by placing the wings on top of each other. 25 It is possible that only one body 10 or 12 will be designed.

Referring to Figure 4, an embodiment of a bandage in combination with a package is shown, which embodiment is in accordance with the invention and therefore uses the same reference numeral 30 as in Figure 1, but with the addition of one hundred elements performing the same function. According to the invention, the side wings 106, 108 are an integral part of the protective bag 100 in which the sanitary napkin 102 is packaged prior to use.

The protective bag 100 preferably comprises pre-cutting members 122, 124, 126, such as pre-cutting lines, which allow the side wings 106, 108 to be released when the protective bag 100 is opened, as will be appreciated, allowing the sanitary napkin to be opened and unfolded, as shown. 5 is shown. The detachable fastening members 110, 112 of the wings 106, 5 108 are located in Fig. 1, as are the connecting ends 114, 116 of the ends 104a and the rear 104b of the cover 104 in which the absorbent bonding element 102 is located. 10 of the assembly members 110, 112 and the connecting members 114, 116 in a transverse shape.

The central portion 128 of the sanitary napkin forming means 101 is devoid of attachment or joining members, such as pieces of adhesive-like product, which provides great flexibility 15 to this central zone.

In addition, it is found that in this embodiment, the removable fastening members 110, 112, which are temporarily protected from premature damage by the protective members 130, 132, form, for example, silicone strips.

Once the protective bag 100 has been opened by the pre-cuts 122, 124, 126 and opened from the folds as shown in Figure 5, it is only necessary to remove the protective members 130, 132 to allow the wings 106, 108 to be attached to the undergarment 140, possibly by superimposing the wings 106, 108. Figure 6 illustrates. The detachable fasteners 112 of the wing 108, which are placed on the inside, for example, are placed against the undergarment 140, while the detachable fasteners 110 of the wing 106, which are also placed on the outside by superimposing on the wing 108, are attached to the wing 108 itself. In one embodiment, the members 112 may be removed.

35 I: 9 89002

As shown in Figures 4-6, the wings 106, 108 are most preferably formed by a single strip 142, which is well visible in Figures 5 and 6, made of a liquid impermeable material, for example a polyethylene-5 film. Of course, any other suitable material can be used. This tape is connected by any means to the cover 104 containing the bonding element 102. It can be easily performed by gluing, for example by placing one or more glue lines 144, 10 which are clearly visible in Fig. 7.

The manufacture of the protective bag 100 with said strip 142 is carried out according to the generally known method of manufacturing individual packages for folded ties.

This method involves the wrapping of pre-folded ties in two or three parts at the end of the manufacture into a polyethylene or other film.

Wrapping is performed by placing the bandage approximately in the center of the film. The edges of the latter are then folded over 20 ties, one on top of the other. These twists are seamed in the middle of the film, along the edges perpendicular to the fold axis of the twists. Finally, the turns are seamed to each other along this axis.

The procedure is similar if it is desired to apply one or more adhesive strips 144 to either the film 142 intended to form the protective bag 100 or the cover 104 containing the sanitary napkin-forming bonding element 102 to ensure the joining of the two parts.

In addition, pre-cuts 122, 124, 126 are designed along the seamed edges of the protective bag 100 to ensure a proper cut to implement the side wings 106, 108. Instead of pre-cut lines, a seam which is not final can be designed along lines 35 124, 126. This method can be easily modified to implement the detachable fasteners 110, 112 of the plugs 106, 108, for example by placing adhesive pieces which are preferably protected from any premature damage by suitable means. protective members 5 130, 132, such as silicone tapes on at least one side.

Several embodiments of this protective bag are possible, shown in cross-section in Figures 7-9 at the same line VII-10 VII of Figure 4. In the embodiment of Figures 4, 5 and 7, the protective bag 100 is implemented at this level of the seam, between the fastening members 110, 112.

In the embodiment of Figure 8, the wings 106, 108 are joined together by an overlapping arrangement, for example by thermal soldering, in the freedom that the side wings 106, 108 are made of a polyethylene film which is specifically heat sealable, the seam line reference number being 152.

A simplified variant can still be devised, shown in Fig. 9, according to which only one of the side wings 106, 108, for example the wing 106, is provided with a detachable fastening member 110 which acts as a closure of the protective bag 100 by superimposing the wing 108 on the wing 106. The opening of the bag 100 then takes place by a simple movement of the wing 108 to separate it from the wing 106. The inner surface of the wing 108 opposite the member 110 can be treated in a suitable manner generally known, for example by cessation, to allow it to be detached from the wing 106. 110 without deletion.

The wings 106, 108 can then be fastened between them from outside the undergarment 140 by a new superimposition of the wings 106, 108 in the same type.

35 I 89002

Of course, the invention encompasses all devices that are technical equivalents of the disclosed members as well as various combinations thereof. For example, instead of using pieces of a label-like product, Velcro-type fasteners can be used to make the removable fasteners 110, 112, the connecting members 114, 116.

In addition, the side wings can be formed in any way. However, it is preferred that these side wings 106, 108 be placed on top of the assembly formed by the cover 104 and the tie element 102. These side wings 106, 108 can be made from a single strip 142 of impermeable material to reliably protect the undergarment from any risk of staining.

The impermeable material used to make the side wings can be coated with an absorbent material to prevent liquid droplets on the wings from staining the undergarment. A preferred solution involves the use of a polyethylene film complex or other nonwoven plastic material for the side wings.

Most preferably, the nonwoven material is comprised of heat-meltable, bleeding fibers that feel soft.

The nonwoven material is bonded to the film by any suitable means, such as: hotmelt gluing, extrusion of the polyethylene film onto the nonwoven material, or thermal bonding by hot calendering.
