Description

Active agent glove and tool for its production

The invention relates to a drug glove according to the preamble of claim 1 and a tool for its production.

Such a glove is described in DE 196 32 312 Al. Other gloves that can be used to apply active ingredients to skin areas are commercially available rubber gloves.

Such gloves are often less attractive because slip between the material of the glove and the skin of the user is possible only under friction. On the gloves, which are often made of thin material, it is often not possible to apply the tensile forces required for tightening without the risk of the material tearing.

However, a simple and safe donning is particularly desirable in the case of active agent gloves, since the outside of the glove is coated with the active ingredient at least in a partial area and it is undesirable for this active ingredient to unintentionally come into contact with skin areas, in particular skin areas of the hand.

The present invention is therefore an agent gloves are created that can be put on easier.

This object is achieved by an active ingredient glove with the specified in claim 1 Characteristics.

In the active agent glove according to the invention only a part of the glove, which typically includes the finger area, must be tightened while the rest of the tightening can be done by moving the remaining portion of the glove from the already tightened part of the glove onto the glove Palm and the area surrounding the carpal area of the hand and if necessary of the forearm unrolls. In this part of the tightening no slip is necessary in the glove according to the invention.

The inventive design of the active ingredient glove also has the advantage that the active ingredient is enclosed between two layers of the inverted glove base. The material of the glove base is made of a material which blocks the active ingredient in order to protect the user's hand from the active ingredient. The active ingredient is therefore well held together between two superposed layers of the base even during storage.

The superimposed two layers of the base also reinforce the everted glove, so that you can safely exert greater forces at the open end of the inverted glove.

Advantageous developments of the invention are specified in the dependent claims.

With the development of the invention according to claim 2 ensures that the drug-coated parts of the glove are completely enclosed between superimposed layers of the base. According to claim 3, the glove itself can be its own packaging. Since the material of the base part is usually made of the active substance blocking material, an outer shell which has this blocking effect can be dispensed with. Where for special reasons anyway an outer shell is used, the security against unwanted escape of the active ingredient is improved

The development of the invention according to claim 4 is advantageous in terms of inexpensive and rapid production of the fluid-tight connection.

The development of the invention according to claim 5 makes it possible to attach a larger amount of active ingredient captive on the outer surface of the glove.

In this case, the development according to claim 6 with regard to advantageous to support a light and uniform distribution of the active ingredient on the skin.

The development of the invention according to claim 7 makes it possible to staple the fibers of the fabric locally under heat.

Also, you can specify in the specified in claim 7 training the textile layer, the textile layer also according to claim 8 simply by the action of heat on the base.

The development of the invention according to claim 9 is in view of good long-term stability of the active ingredient glove and in view of a uniform and slow release of the active ingredient of advantage.

In an active agent glove according to claim 10 that portion where the glove must be grasped to unroll the root portion over the palm of the hand and the carpus of a user's hand is free of active ingredients. Thus, when rolling the root section no special care needs to be taken to prevent contamination of the attractive hand with active ingredient.

A drug glove according to claim 11 and 12 can be set in a very simple manner after putting on the skin of the user. Thus, the glove does not unintentionally move down from the user's hand again when the active ingredient is rubbed on the skin.

The same advantage is achieved with the developments of the invention according to claims 13 and 14.

In an active agent glove, as indicated in claim 15, the root section can be particularly easy to put over the finger portion.

In the case of an active agent glove according to claim 16, it is also possible to manage with only slight or vanishing inclinations in the finger section and root section.

A tool, as indicated in claim 17, is particularly well suited for quickly and easily everting the root portion over the finger portion.

When using a tool according to claim 18, a slipped glove can be obtained with a particularly small thickness, which is advantageous in terms of storage and shipping. In this case, the development of the invention according to claim 19 in terms of keeping small frictional forces of advantage.

The development of the tool according to claim 20 is in terms of simple and safe removal of the invaginated active ingredient glove from the Stülp tool advantage.

The invention will be explained in more detail by means of exemplary embodiments with reference to the drawing. In this show:

Figure 1 is a plan view of an active agent glove, shown in solid lines in a staggered delivery configuration of the finger portion and root portion, and shown in phantom in an application configuration, with a portion in the delivery configuration the root section is broken away;

Figure 2 is a view similar to Figure 1 but showing a finger-agent glove;

FIG. 3: a longitudinal mid-section through the active substance

Glove according to Figure 2, in which the dimensions are shown exaggerated perpendicular to the glove plane; and

Figure 4: a schematic representation of a tool which is used to evert the root portion over the finger portion. FIG. 1 shows an active agent glove comprising a base part 10. The latter has essentially the shape of a rectangle with slightly oblique longitudinal edges. The base 10 consists of two film layers welded together on three sides (upper edge, side edges) while the last side (bottom of Figure 1) remains open.

The glove is drawn for clarity's sake as if the material of the base 10 were opaque. This also applies to the other figures.

The base 10, in the configuration shown in solid lines in Figure 1, in which it is delivered to a consumer, has an internal part which later substantially receives the fingers of a user's hand and is referred to hereafter as the finger portion 10A. Over the finger portion 10A, a part of the base 10 receiving under the conditions of use of the palm and the carpus is slipped, which will be referred to below as the root portion 10B.

As can be seen from FIG. 1, in the delivery configuration shown by the solid line, the free edge R of the root portion 1OB has been extended beyond the upper edge E of the finger portion 10A by a distance d.

The base 10 thus forms a 4-ply structure in the area in which the finger portion 10A and the root portion 10B overlap, in the upper area only a 2-ply structure. As shown in Figure 1 in an enlarged detail, the material of the base 10 comprises a film 12, on which a textile layer 14 is mounted, which in turn carries an active substance layer 16.

The textile layer 14 may be made of a woven or non-woven fabric comprising a proportion of weldable fibers. The film 12 is also made of weldable material, and the textile layer 14 is connected by spot or surface welding to the film 12.

The drug layer 16 may be a cream layer, a liquid absorbed by the textile layer 14, or a layer of microencapsulated drug.

The inverted active ingredient glove is sealed in a dashed lines indicated outer shell 18, the material also does not pass the drug.

It can be seen that in the delivery configuration of base 10 shown in solid lines in Figure 1, the active agent layer is completely between the first and second layers of the 4-layer structure counted from above and that all outwardly facing surfaces of the glove are drug-free. Also, the pocket formed by the finger portion 10A is drug-free on the inside.

A working configuration of the active agent glove is indicated by dash-dotted lines in FIG.

In the case of active ingredients in which an unwanted contact with the skin of the user is to be avoided, the film 12 is a material which has a blocking effect for having the active ingredient. Such agents which are not intended to be inadvertently in contact with the skin of the user include tanning agents, but also agents for promoting blood circulation to the skin, such as those used to treat lumbago, sprains, etc.

In order to be able to determine the glove after putting it on the skin of the user, an uppermost layer, which represents the rear outer surface of the glove after unrolling the root section 1OB, is provided on the bottom side of FIG. This comprises a film piece 24 which carries a continuous adhesive layer 26. A portion of the adhesive layer 26 is protected by a cover sheet 28, the remainder of the adhesive layer 26 serves to attach the fixing tab 22 to the root portion 10B.

As can be seen from Figure 1, an end portion of the root portion 1OB, which is slightly larger than the upper edge of the fixing tab 22, free of drug. In this area, the root portion 1OB can be grasped and moved without danger of contact with the active substance.

The slipped-in active ingredient glove described above is welded into the outer shell 18 in the factory, which prevents the escape of active ingredient even during long storage. This outer shell 18 is cut open to then supply the active agent glove to its destination.

The exemplary embodiment according to FIG. 2 is largely similar to that according to FIG. 1. Functionally corresponding com- Components of the glove are again provided with the same reference numerals and will not be described again in detail below.

The finger portion 10A is now formed with individual fingers, so as to obtain a total of a finger glove.

The root portion 1OB is sealed by a weld 34 in the area beyond the finger portion 10A. Since the material of the base 10 blocks the active ingredient, so obtained by the glove itself at the same time a dense packaging for the drug. An outer packaging can thus be omitted. Where such is provided anyway, gives a double good barrier effect for the drug.

Instead of an adhesive flap according to FIG. 1, which is used to gather the glove in the region of the wrist and to fix it in the gathered geometry, an adhesive layer 36 is provided on the side of the root section initially located on the outside in FIG skin-friendly adhesive material applied as it is used for plasters. The adhesive layer 36 is protected by a cover layer 38 until use.

As can be seen from FIG. 2, the side edges in the area of the joint line between the finger portion 10A and the root portion 10B have a downwardly diverging edge portion 42. It is thus achieved that the longitudinal edges of the root portion 10B are spaced from the longitudinal edges of the finger portion 10A transversely spaced, which is a simple inversion of the root portion 1OB in the production and a simple rolling of the root Section 1OB favors when putting on the glove.

The glove described above can be produced as follows:

From two superimposed films, the base 10 is produced by welding. On the base 10, the textile layer 14 is applied in the desired area, e.g. by area or area welding. Then, the textile layer 14 is provided with the active agent 16, e.g. by screen printing or another stencil method.

Then the glove is placed between two frame parts 44, 46 whose edge contour corresponds well to the edge contour of the finger portion 10A in the region of the longitudinal edges. Preferably, the frame parts 44, 46 are provided with a recess in areas corresponding to active substance-coated areas of the finger portion 10A.

The finger portion 10A is now clamped between the frame members 44, 46 by exerting a force directed perpendicularly to the plane of the drawing of Figure 3, and the root portion 10B is slipped over the small thickness frame members 44, 46.

The frame members 44, 46 are preferably made of a low friction plastic material for the base material. They may also have a corresponding surface coating (e.g., PTFE).

The frame parts 44, 46 have in the region of the joint between the finger portion 10A and root portion 1OB at least one recess 50, at which then the can take four layers of the everted glove, or are interrupted there to pull down the everted glove easily from the frame parts 44, 46 comprehensive Umstülp tool.

It is understood that one can perform the Umstülp process described above as a manual operation with appropriately trained machines.

To apply the active ingredient glove, an existing outer casing is first cut open on one side (example according to FIG. 1), or the glove is opened by cutting just below the welded seam 38 (example according to FIG. 2). Then the fingers of the user's hand are placed in the inverted glove, whereby one can vigorously tackle the open four-layer and drug-free end of the inverted glove. Then, the root portion 10B of the glove was rolled from the finger portion 10A over the palm and up to or over the carpal.

By peeling off the cover films, the adhesive layer 26 or 36 is then exposed. And by shirring the wall material in the area of the wrist and fixing the shirred material with the Fixierlasche 22 or by pressing the adhesive layer 36 to the skin of the glove is fixed in the hand of the user, so that the glove is not inadvertent even when distributing and rubbing the drug is stripped off.
