Description

in DK 171093 B1

BACKGROUND OF THE INVENTION The present invention relates to a one-size panty comprising a waistband for enclosing a user which is knit at an edge area of the panty bottom to form a crotch area separating two non-attached portions of the panty-piece strings at the bottom of the panty for forming leg openings, which panty is made of a basic fabric of elastic threads distributed over the height of the body part, which generally extends in the circumferential direction of the body part to provide an elastic contraction in the circumference direction of the body part. The invention further relates to the use of the one-size panty as a diaper brief.

It is known to make panties by knitting with different designs to obtain the best possible fit without the need for post-fabrication of the panties. To achieve a fit and elastic contraction, it is possible to use different mesh types, firmer knitting and the like instead of knitting the elastic threads. The present invention relates to the panties which use elastic threads and to a lesser extent the mesh type to form the fit.

Although several solutions have been proposed to achieve a fit that makes the briefs as widely applicable as possible, so-called one-size briefs, the known briefs are associated with certain disadvantages.

20

In order to obtain a panty that is stuck on a relatively small user, a large number of elastic threads are required in the circumferential direction. However, such a panty gives a very large pressure effect on a relatively large user. If the panty is to fit the large user, it will be too loose for a relatively small user. Especially in diaper briefs this is a problem. In such panties a relatively strong elasticity is required to achieve a satisfactory diaper fixation. Therefore, for the larger user there will be a very high risk of strong local pressure effects on the elastic threads. This causes nuisance and can also impede free blood circulation.

30 Solutions for forming one-size panties have been proposed in which, at various distances over the height of the body part and at the side seams of the panties, a seam is formed which extends partially into the panty itself. This stitching of the body part at certain points with distance above the height of the body part can be broken. By breaking a larger or smaller part of the sewing it becomes possible to produce a panty suitable for a larger or smaller user. However, the panty will comprise a relatively large amount of material concentrated at the side seams. This will naturally give smaller users a discomfort due to the elastic forces in the circumferential direction which will push this folded amount of material against the user with a large local pressure effect.

DK 171093 B1 2

Furthermore, there will be a risk that a user will break a large part of the sewing. In this way, the panty will be unsuitable for use by a relatively small user, as there is too little elasticity in the circumference direction of the finished panty. This will especially cause problems 5 in diaper briefs.

A panty according to the present invention can be considered a further development of a flat knit panty described in U.S. Patent No. 3,656,324. Thus, materials, knitting types, mesh size, embodiments, etc., which are explained in U.S. Patent No. 10, may also be used in connection with the manufacture of the panty of the present invention. Alternatively, the panty according to the invention may also be made by knitting.

It is the object of the present invention to alleviate the disadvantages of the known briefs, in particular the prior art one-size briefs, and especially briefs for diaper fixing, by providing a brief of the type mentioned initially which can be manufactured with an elasticity which allows that it is used by relatively small and relatively large users without giving local pressure and without being too loose.

This is achieved in accordance with the present invention with a panty which is characterized in that at least a portion of the elastic threads only form meshes over a portion of these threads in the circumferential direction of the panty to form intermediate areas where the ground tissue is pressed outward to form a waveform. 1 2 3 4 5 6 7 8 9 10 11

A finished panty, in which a portion of the elastic threads are masked only by a portion of their circumference 2 in the circumferential direction, with the other meshes in the base tissue of the body of the panty, 3 will appear in a waveform. The elastic strands distributed over the height of the body part 4 will contract the areas oriented in the direction of the body part, which are knit 5 together. In this way, the intermediate areas not connected to the 6 elastic threads will be pressed outwards, so that the panty appears with the wave-shaped 7 body part, the waves being oriented with their lumbar orientation in the height direction of the panty. In the direction 8 perpendicular thereto, that is in the circumferential direction, the waves at the location of the 9 panty on a small user will provide the necessary elasticity to secure the panty securely. If the panty is used by a larger user, the waves will be popularly smoothed out 11. This will result in greater circumferential elasticity. However, there will be only a relatively small change in the elastic force effect.

DK 171093 B1 3

Furthermore, the force effect will not be localized in some points. Instead, there will be an even distribution of the elastic force effect against the wearer over the entire circumferential direction of the panty. The panty can thus be used by a small user, where the waves themselves give rise to the necessary elasticity, and by a larger user where 5 elasticity occurs due to the stretching of the elastic threads in the smoothing of the waves. The panty is easy to use as it does not require any prior preparation. Furthermore, the panty will always be suitable for use by a large or small user, regardless of whether it has been pre-stretched to a maximum extent.

The panty according to the invention will not cause a large amount of material in certain areas, for example at the side seams, which can give rise to bothersome pressure effects on the user and which will also make the panty aesthetically unattractive due to the bulges that occur. by these large quantities of material.

Since the panty in any application will provide a substantially uniform elastic tension which can be predetermined depending on the number of elastic threads, the panty will be particularly suitable as a diaper fixing panty. It will be possible to make the panty by flat knitting on traditional double-skinned Raschel machines or by knitting on traditional circular knitting machines.

By the body part of the panty in this application is meant the parts which are intended to enclose the user and which extend all the way down to the crotch area between the two leg openings. Thus, the elastic threads may be located over the entire height of the panty including areas for a waistband to enclose the wearer's life and an elastic edge area adjacent to the leg openings. Thus, the waistband and leg cuffs will also appear with the waveform and be able to accommodate users of different sizes. In order to obtain a suitable elasticity, it has been found advantageous in the adult panty to use between 10 and 20 elastic strands, preferably between 14 and 18 elastic strands.

The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 shows an embodiment of a panty according to the invention; FIG. 2 shows a partial knitting diagram of the one shown in FIG. 1, and FIG. 3-5 show a partial view illustrating the waveform of a panty of the present invention.

Fig. 1 shows a largely rectangular head 1 for a panty according to the invention made by flat knitting. The rectangular head 1 is positioned superimposed on a substantially similar back piece 2, which is visible only at leg openings 3, which are located on each side of a knit crotch region 4 at the bottom of the panty. The panty 1 om-5 includes a body part 5 intended to enclose the user. The front piece 1 and the back piece 2 are knit along side edge areas 6 to form side seam 7. The knit in the edge areas 6 corresponds to the knit made in the step area 4.

The front piece 1 and the back piece 2 are made in endless webs on a conventional knitting machine, for example a Raschel knitting machine where one of the needle rails is used to make the front piece 1 and another needle rail is used to make the back piece 2. The endless webs are cut transversely for forming separate panties. This cut takes place in mesh-fixed cut strips (not shown) at each side edge.

15

At the top of the body part 5 a waistband 8 is formed which encloses a waist opening 9. The waistband 8 is obtained in a manner well known in the art by a large number of elastic threads 10.

The panty is made with a number of elastic threads 11 which generally extend in the circumferential direction of the body part. In the illustrated embodiment, this means that the elastic threads 11 extend between the edge areas 6 of the front piece 1 and the back piece 2 respectively. The elastic threads can provide an elastic contraction in the circumferential direction of the panty in a well known manner. This ensures that the panty is attached to the user.

25

Elastic threads will generally form, in whole or in part, a portion of the ground tissue in the front piece 1 and the back piece 2 formed with a mesh-like open mesh structure. This mesh structure is well known to one of ordinary skill in the art and will therefore not be described in detail. It is also well known to use elastic threads which are knit 30 with the ground tissue over the entire circumferential direction of the body. These known elastic threads are indicated by 1Γ.

According to the present invention, a portion of elastic threads 11 is only partially knitted with the ground fabric over the extension of the thread in the circumferential direction of the body member. In the illustrated embodiment, the yarns 11 are formed of yarns in the form of highly elastic elastane which is knit together with the ground tissue to alternately form four stitches and extend freely over the next four stitches formed in the ground fabric.

DK 171093 B1 5

A total of sixteen elastic threads 11 are used above the height of the body. The threads 11 are shown only on the front piece 1, but corresponding threads will be placed on the back piece 2. The threads 11 will give the panty a waveform, which will be explained later with reference to FIG.

3-5. The waveform will allow the panty to be used with a pleasing elasticity on a small user and a large user.

It is by the insertion of the elastic threads 11 in the body part 5 that the panty according to the present invention differs from the known panties. The actual stitching of the elastic threads is shown in the knitting diagram of Figure 2. It is noted that the knitting diagram of Figure 2 is only partial and that it is possible to vary the extent of the individual areas. Thus, the waistband 10 may be larger or smaller, and the edge area 12 located in the immediate vicinity of the leg openings 3 may also have different extents.

15 The knitting diagram shows that the elastic threads 11 in the region 13 extending in the height direction 14 of the panty 1 form meshes 15 with the other basic tissue 16, then follows an area 17 which is also oriented in the height direction of the panty 14, where the threads 11 not knitted with the ground fabric 16. The ground fabric is formed with a mesh-like knit of textured yarns, for example made of nylon or polyester or 20 elastangams.

In the waistband area 10, elastic threads 18 are used in a large number to form a very elastic waistband in a manner well known in itself.

It is noted that the regions 13 and 17 extend over the entire height of the body part 1, that is, also in the region of the waistband 10. After the knitting, the panty will appear with a waveform shown by an exaggeration in FIG. Third

In FIG. 3-5 are schematically shown how the yarns 11 and the ground tissue 16 appear in different application situations. In FIG. 3, there is shown a situation where the panty is finished knitting and has undergone a well-known fixing process. The panty is ready for use in this situation. In FIG. 4 illustrates a situation in which the panty is partially stretched, i.e. a situation where the panty is placed on a small user. In FIG. 5, there is shown a situation where the panty is heavily stretched, that is, a situation where the panty is placed on a large user.

In FIG. 3, it is seen how a waveform 19 is formed in the base tissue of the panty 16. The waveform has wave peaks 20 in the regions 13 where the elastic threads 11 are knit together with the ground tissue 16. There are wave valves 21 in the regions 17 where the elastic threads 11 The elastic strands 11 are high elastic strands, it is possible to impart a very strong extension to them without the elastic force exerted increasing greatly.

5 In the situation shown in FIG. 4, the elastic threads 11 are elongated and wavy ground tissue 16 is partially smoothed. Thus, the elasticity of the basic tissue does not make a particularly large contribution to the elastic force when the panty is applied to a smaller user. This elastic force is primarily provided by pulling the elastic threads 11.

10 In FIG. 5, a situation is shown in which the ground tissue 16 is extended and extends substantially parallel to the elastic threads 11.1 this situation a stretch occurs in both the elastic threads 11 and in the ground tissue 16. As the ground tissue 16 is formed with an open netlike structure, this will ground tissue 16 have some elastic force. However, it is well known to one of ordinary skill in the art that the elasticity that occurs in the ground tissue can be very easily controlled using various mesh types.

It will be possible to vary the panty according to the invention. Thus, it will be possible to position the elastic threads 11 so that they extend obliquely from the crotch region upwards and 20 outwards in a mean-like pattern. This allows the elastic threads to have a position similar to the side edges of a diaper. This will make the panty particularly useful as a diaper fixation panty. Not only does a printing effect be obtained along the side edges of a diaper, but also an elasticity in the circumferential direction of the diaper so that it is fixed around the wearer's life. However, the panty will also be useful as a diaper panty with 25 elastic threads 11 extending circumferentially in the manner illustrated in Figure 1.

It will also be possible to make the panty by circular knitting. In this embodiment, no side seams will appear. The most important feature, namely the partial meshing by the elastic threads 11, will also be found in such an embodiment.
