Normal scarves are also known. It is about knitted or woven textiles that are in the cold season or as fashion accessories Find use. Sometimes scarves are also considered top Layer of medical wrap used in the neck area. The inner layers of such wraps, the z. B. with hot or soaked in cold water are made of cotton pieces of tissue and should each after a few uses getting washed. These well-known house wraps are strong and are therefore only used at home.

For many applications, it would be beneficial to have a scarf to have a medical effect on the one hand, on the other hand has an attractive appearance and a Is disposable.

To this end, the invention creates a scarf according to claim 1.  

The scarf according to the invention can be stored for a long time until it is used because the drug is in the microcapsules is reliably withheld and only under influence of body heat and / or sweat and / or pressure or Friction is released. Pulp-based nonwovens and possibly plastic admixture are considered inexpensive Bulk goods available on the market and can also be relatively easy with microencapsulated drugs "to fill". After consumption of the drug, the whole Scarf just to be thrown away. In addition, the Scarf also good swallowing ability for sweat.

The invention also gives a scarf, at which one specifically targets the volatile drug in the Scarf areas that are responsible for mechanical destruction of the microcapsules is particularly easy for the user are accessible and from which ascending medication vapors reach the respiratory tract particularly well. One can so z. B. a scarf with an antidote to hay fever fen realize the release of the drug by the user quickly and easily at the time can take place, to which he goes into a meadow area emotional.

Advantageous developments of the invention are in Unter claims specified.

The development of the invention according to claim 2 enables it appeals to you externally at low overall costs to have a scarf that looks like an ordinary decorative one Scarf has longer end sections, which from the neck of the Hang down and tied or folded can be.

The development of the invention according to claim 3 is in  With a view to absorbing sweat well when dry keeping the skin of the user beneficial.

With the development of the invention according to claim 4 ensures that moisture and heat are inside the Scarves jam, which is a particularly effective release of the microencapsulated drug guaranteed.

The training according to claim 5 is both in With regard to a particularly effective retention of the Warmth as well as with an appealing appearance the scarf is an advantage.

The further development of the invention according to claim 6 serves to give the scarf an attractive appearance, so that this is not a medical device for the purpose but is also perceived as jewelry.

The invention based on an embodiment example with reference to the drawing, in more detail tert. In this show:

Fig. 1: A top view of a scarf impregnated with a medicament and on a section of an endless web from which the scarf is made;

FIG. 2: A vertical section through a section of the shell shown in FIG. 1 on an enlarged scale; and

Fig. 3: A similar view to Fig. 1, in which a converted scarf is shown.

A scarf, designated overall by 10 in the drawing, has a core layer 12 made of nonwoven fabric. The nonwoven in turn consists of cellulose fibers 14 , to which smaller proportions of plastic fibers are mixed. Such nonwovens are known per se.

In the loose core layer 12 14 microcapsules 16 are arranged between and on the individual fibers, z. B. attached using a water-soluble binder. This installation can be done by spraying an appropriate emulsion, by immersion or by dusting the microcapsule.

The microcapsules 16 each have a wall material which can be decomposed by body heat and / or the action of sweat. Inside the microcapsules there is a medicament, e.g. B. an evaporable by body heat essential oil such as peppermint oil, optionally enriched with volatile synthetic agents against cold diseases.

The medication impregnation, which is obtained by the microcapsules 16 contained in the core layer 12 , extends only over a central region B of the shell 10 , the length of which is approximately 10-20 cm longer than the central circumference of a neck, so that the medication impregnation also without the exact positioning of the shell 10 certainly enough around the neck of the user. Typically, the impregnated central region B can therefore have a length of 60 cm.

A barrier layer 18 covers the impregnated area B on the outside of the scarf. The barrier layer 18 can typically be formed by a transparent thin plastic film which is metallized on one side, e.g. B. is steamed. If desired, the barrier layer 18 can also extend over the entire length of the shell for aesthetic reasons. Conversely, the barrier layer 18 can also be a transparent plastic layer, and the outside of the core layer 12 can be decorated by printing, in particular in the area of the two scarf end sections E, which adjoin the impregnated central area B on both sides and typically have a length of 40 -80 cm. Other types of decoration of the end sections E may consist of mechanical deformations, e.g. B. curls, ripples, punched openings or fringes, as indicated at 20 .

You get a total of a scarf 10 with an appealing outside.

On the body side, at least the impregnated area B of the core layer 12 is provided with a cover layer 22 , which is permeable to moisture, but does not itself store moisture. In this way, the skin of the user is kept dry, even if the fibers 14 of the core layer 12 have soaked up moisture after the shell 10 has been worn for a long time.

The scarf 10 described above is cut from an endless material 24 , which is indicated by dashed lines in FIG. 1. This continuous composite material can be easily manufactured in a continuous process from inexpensive parts.

From the above description of the scarf 10 it is also clear that it only needs to have a small thickness and can therefore be worn instead of a normal scarf. After use, the scarf 10 is thrown away; if desired, it can also be worn as a pure jewelry scarf after the impregnation of the medication has been exhausted.

In the exemplary embodiment according to FIG. 3, parts of the scarf which have already been explained above with reference to FIGS. 1 and 2 in a functionally equivalent form are again provided with the same reference symbols. The following differences exist:

The micro-capsules 16 containing a volatile hay fever agent are provided in the end regions E of the scarf 10 and have a wall material which can be destroyed mechanically by pressure or rubbing. The area B lying around the neck is free of medication microcapsules 16 for reasons of economy, since the latter can only be destroyed there with greater difficulty and with less effectiveness by the user.

Furthermore, the barrier layer 18 is omitted.

It goes without saying that the exemplary embodiments according to FIGS. 1 and 3 can also be combined and the medication impregnation on the body side and on the outside of the scarf can also be provided over the entire longitudinal extent if there are no cost reasons against this.

Also, one can according to the embodiment FIG. 3 instead of the medicament-containing microcapsules, a fragrance containing microcapsules use.

It is common to all of the exemplary embodiments that the nized scarf in its dimensions, especially its Thick a normal cotton, silk or wool scarf is similar, as loose nonwovens made of absorbent fibers are available, even with a small thickness sufficient absorption capacity for microcapsules and one have sufficient absorbency for sweat.

The scarf can also be used because of its small thickness fold the table wrinkle-free so that there is good surface contact between the body side of the scarf and one featured there guaranteed drug impregnation and skin is.
