, 101359 Operating aid for a mechanically detachable object

The invention relates to the use of one or more objects which are fixed in a planarly extending, particularly flexible support or cover layer but which are mechanically releasably placed, such as in the form of therapeutic systems, patches, labels or the like, in the support or cover layer, or in tears. .

Several methods are known for permanently arranging objects on their base and removing them if necessary. This may be intended, for example, for easy access. This possibility can be used in particular when it is desired to protect the specially treated upper surface of an object from all influences. Thus, for example, contact adhesive layers for labels, but also for patches and other objects, which are covered and protected with a removable protective foil until the time of use 20, are known.

Removing objects from the support layers or cover; ·. removing the layer to release the surfaces to be protected becomes problematic, especially when it is possible to! a bond between the two materials.

25 This applies to a considerable extent when the protective surface of the article must be protected from damage and / or contamination, for example by the adhesive layer of the adhesive layer. · To the detriment of the mechanical effects of sensitive upper surfaces to maintain integrity and to seal the surface, for example to prevent evaporation of volatile components on the surface, etc.

**. · ‘Especially when trying to separate parts | with a nail, knife or other means *: ··· 35 unexpectedly touches or even damages the surface to be protected and may cause the parts not to be completely detached from each other but to leave parts of the support or cover layer in the protected area. surface and can only be removed with ease and without damaging the surface to be protected.

5 Such a procedure should be refused in particular where the surface to be protected is a sterile dressing surface, a skin contact layer of a therapeutic patch, or a reactive material on the surface, such as in pharmaceutical tissues which may come into contact with the skin when administered topically, e.g. according to patent application P 39 01 551.3 it is proposed to be treated with an actinic cornea in a patch system.

To achieve this object, it has already been proposed 15 that the support or cover layer have straight cuts or tear lines, so that by bending and / or pulling the support or cover layer, their parts can be removed from the object adhered to them. But the perfect complete and simple release and detachment of the upper surface of the object from it is not so certain,. especially in the case of a delicate object such as a therapeutic one; patch or plastic product or very flexible. a support or cover layer, which may be a thin aluminum foil, an aluminum laminate, a polymer foil or the like. Especially for small objects with a small • ♦ * ♦♦ · * protected surface, it is difficult to release it completely. Also, the selective removal of individual components from the article and the support or cover layer has not been satisfactorily resolved.

: * · *: 30 U.S. Patent No. 3,230,649 discloses making curved cuts or tear lines in a support foil, such that when the material is bent, the adhesive material forms an adhesive portion and is retractable. However, this solution does not provide a satisfactory method for the complete and undamaged separation of the interconnected parts, since usually the remainder of the support layer must be removed from the object with difficulty with a fingernail or an auxiliary tool.

It is also known that when several objects or objects belonging to an object are used, they are connected to each other by some kind of release tape, and by pulling from the overhanging part of the tape the parts joined together can be pulled out of the support layer in one step. However, the individual parts must be removed from the release tape before use.

Despite the relatively expensive manufacture, this known arrangement only allows several objects or parts of objects to be removed at the same time, and this method is therefore only suitable for relatively small objects. It is known that there are strips or strips of suitable material, such as plastic, textile or metal, between the support layer and the objects placed on it, so that they reach at least at one end over the object or part, whereby separation is possible. However, this system and structure is san-gen expensive and despite the fact that it is not always: ·. useful.

«I« '... EP 0 284 963 proposes the use of Figure 1; lane removal assistance. The detachment aid is intended for a mechanically detachable component 1.2 with a planar 25 flexible support material 1.1 and consists of a curved section of each component 1.2 in the support material 1.1 and a tear line 1.4. By pressing the support material 1.1 with a force component perpendicular to the contact surface of the component 30, the part in the tear line of the component or in the shear line bends in the direction of the component or components.

• · · • · In this case, at least a part of the component 1.2 detaches from the cutting or: tear line 1.4 in the support material 1.1 adjacent to its edge region 1.1 and thus provides the adhesive part 1.3 in the component 1.2) in order to: component 1.2 is completely released from the support material 1.1.

Although the proposed solution offers trouble-free removal of such adhesive components, the adhesive surface of the component must be adhered to with the fingers, thus creating the possibility of a finger contaminating effect with the reactive material of the component.

The object of the invention is to provide an operating aid which avoids the above-mentioned disadvantages of the known solutions and which allows easy and in the above-mentioned safe removal of objects attached to the support or cover layer but mechanically removable from the support or cover layer without the need for contamination of the contact or protective surface. or danger.

This object is achieved according to the invention by the operating aid according to claim 1. Other suitable embodiments of the invention are described in the other claims.

With the aid according to the invention, it is achieved that, in the case of only one object or also several objects, when they are held by the support or cover layer, but mechanically detachable, always easily and securely; a predetermined part of the support or cover layer comes off; · · _ with the object attached to it, the support or cover layer! at the same time releasing a predetermined part of the surface of the object to be protected, without the need or danger of hand contact, and allowing the object to be easily and comfortably removed from the handpiece. to its next destination.

· / · / · The invention is illustrated in the drawing by way of example::: 3 0 and will be explained below with reference to it, ·· *. where: • · · -1 • · Figure 1 shows a square support or cover layer with a rounded | Fig. 2 shows a part of the support or cover layer detached from the support or cover layer of Fig. 1 together with the article, Fig. 3 shows a modification of Fig. 1, Fig. 4 shows a second modification of Fig. 1 and Figure 5 shows an embodiment of placing several objects on the same support or cover layer.

According to Figures 1 and 2, an object 2 is shown centrally in a circular cross-section on a square-made support or cover layer 1. wherein the support or cover layer 1 and the object 2, which may be a label, a patch or a therapeutic product or the like, must be attached to the contacting or opposing contact surfaces 15 but mechanically detachable.

With respect to the intended horizontal centerline, the support or cover layer 1 has at its right side a substantially triangular cut or tear loop-20 and 3. This cut or tear line 3 may have, for example, a groove extending to a portion of the thickness of the support or cover layer; also perforation, which may have more! . more or less closely spaced perforations with more or less 25 holes. These cuts or tear lines are made so that more or less long cuts are more or less between a large number of heels. In this case, it must of course be taken into account that the mechanical stability of the support or cover layer is sufficiently high to avoid premature and careless separation, e.g. at the packaging stage.

• · · • · * .. * Depending on the sensitivity of the object 2 to be protected, the structure may also be as follows: the cuts or tear lines under the object 2 are not grooved exactly to the support ·; ··· 3 5 or the thickness of the cover layer through, while the areas outside the object 2 6 101359 may have perforations or cuts with the bases between them. In any case, the structure must be such that the surface of the article 2 is securely protected and that the part 4 of the support or cover layer 1 defined by the cuts or tear lines 3 can be reliably and easily separated from the rest of the support or cover layer in a predetermined shape and manner. that the surface to which the part 4 and the object 2 are attached is illuminated in such a way that the proper removal of the object 2 from the support or cover layer is ensured, as is the secure retention of the object 2 in the part 4 when it is removed from the rest of the support or cover layer.

As can be seen in particular from Figure 2, the lined area 4a of the part 4 is large enough to provide a secure grip for detachment from the rest of the support or cover layer 1.

Instead of a square shape, the support or cover layer 1 can also be of any desired shape, just as the object 2 does not have to be not only round but of any imaginary shape, depending on the particular case. application. Equally, part 4 can be formulated in a completely different way, according to need and purpose. Finally, it is stated that the placement of the part 2 in the middle of the support or cover layer 25 1 is only an example, since the object 2 can be placed at the desired location, asymmetrically, just like it • · · V; is possible with the placement and design of part 4.

Such a possibility of asymmetrical arrangement of the part 4 of the support or cover layer 1 and in particular of the object • ·; 1j1. 30 2 is shown in Fig. 3, in which the section or tear line 3 is arranged on the right edge, displaced upwards, so that the part 4 is fixed to the object 2 in an asymmetrical region.

This asymmetrical arrangement may, in case 35, facilitate the applicability and usability of the articles 2 when the article 2 is moved into use by a detached portion 4 covering a portion of the article 2 and extending into a portion 4a beyond the article 2 and placed in contact with the article without contacting the article. 5 drops. In this case, the object is first attached from its free part to the application, then the detached part 4 of the support or cover layer 1 is removed and finally the object is pressed in contact with the application over its entire surface. In this case, at no point may a finger or other auxiliary device, such as tweezers, touch the surface of the object pre-treated with the active substances.

In order to facilitate separation or detachment, according to Fig. 4, there are small protrusions in a certain area 4a of the part 4 for gripping the fingers, whereby the holding 15 is ensured. Instead of bumps, of course, there could be a groove or the like.

An example of the placement of several objects 2 or also parts of an object on a common support or cover layer 1 is shown in Fig. 5, in which case the structure of the support and cover layer 1, as well as the placement and structure of the objects 2 and the cutting or tear lines 3 or the tear members 4 or gripping members 4a formed by them do not have to be symmetrical, but rather some other suitable and desired structure can be realized without side effects.
