Description

Description: TECHNICAL FIELD A dosing aid for an article (hereinafter referred to as “article”) adhered to a support or coating layer extending in a sheet shape in a mechanically removable manner.

The present invention provides a particularly flexible support that extends adhesively in the form of cuts or predetermined cut lines formed in the support or cover layer but extends in a plane in a mechanically removable manner. It relates to a dosing aid for one or more articles such as medical systems, plasters, labels, etc. located on a cover layer.

<Prior Art> Various methods are known in which an article is adhesively placed on a substrate material and, if necessary, is removed. This is, for example,
It may have the purpose of keeping the article valid in a manner that is easily accessible. However, if the particular surface of the article has to be protected from being affected until it is used, this method is particularly utilized. For example, it is known to coat and protect plaster and other articles with pressure-sensitive adhesive layers as well as labels with protective films that are removable until use or administration.

Separating the article from the support layer to expose the protected area, i.e. separating the covering layer, is particularly difficult when considering the adhesive composite between the two materials. This keeps the adhesiveness of the adhesive layer, for example, after and after the surface of the article to be protected has been exposed by removing the support or coating layer, so that the surface of the surface which is sensitive to mechanical influences is preserved. When it is necessary to prevent damage and / or contamination for maintenance, for example, for sealing the surface to prevent escape of volatile components applied to the surface, etc. This is especially true.

In particular, when attempting to separate the two with nails, knives or other devices, undesired contact or even damage to the surface to be protected occurs. Furthermore, a complete separation of the two does not occur, i.e. a part of the support or of the coating layer remains tacky on the surface to be protected, but it is very difficult to remove it further from the surface without damaging it. Difficult to do.

Such a process is particularly suitable when the protected area is a sterile surface of a bandage, the skin contact layer of a medical plaster, or when the surface contains an active substance such as a medicinal substance. Not particularly applicable. Such substances are topically administered and contacted only on the skin at the site of administration, which is for example employed in the plaster system in West Germany for the treatment of actinic keratosis. It is proposed in Patent Application No. P3901551.3.

In order to solve the above-mentioned problems, a linear cut or a predetermined cut is provided so that it can be removed from the article that is adhesively bonded to the layer by bending and / or pulling apart a part of the support or the covering layer. It has been proposed to provide the cutting line of (1) in the support or the coating layer. However, the impeccable, complete, easy exposure or corresponding removal of the surface of the article is especially relevant for sensitive articles such as medical plasters, plastic moldings, very flexible thin aluminum foils, It is not guaranteed to think of aluminum laminates, polymer foils, etc. Especially for small articles having a small surface to be protected, it is difficult to expose it completely. However, the selective separation of the individual parts of the article from the support or coating layer has not yet been completely resolved.

U.S. Pat.No. 3,230,649 describes the use of curved cuts or predetermined cut lines in the support film,
This is done by bending the article to create a gripping margin for the support material so that it can be peeled off. This solution, however, originally has generally required that the remaining part of the support layer be permanently removed by nails or aids, so that a complete, break-free separation of both parts connected to each other is required. It does not provide a satisfying way to do it.

When using some kinds of articles or some number of connected articles, these are used as release tapes.
It is also known to connect by means of tapes) such that the protruding parts of the tape can be removed from the support layer in one operating step by pulling on the protruding parts of the tape. However, they must be released from the tear-off tape before the use or application of the individual parts.

In addition to being a relatively expensive product, this known structure is limited to the simultaneous removal of a small number of articles or parts of articles and the simultaneous removal of relatively small articles or parts thereof. There is.

A strip or thread of a suitable material, for example plastic, fiber or metal, is provided between the support layer and the article lying above it, with these strips or threads protruding from one end of the article or part thereof. It is also known to allow separation. However, this structure and its formation are not very costly and not universally applicable.

European Patent Application No. 0284963 proposes a separating aid as shown in FIG. This separation aid is
It is intended for a mechanically removable substrate (1.2) adhered to a planar flexible support material (1.1). This is for each substrate (1.
2) has a non-linear cut or predetermined cut line (1.4) in the support material. By applying a force to the support material in a direction perpendicular to the substrate contact surface, it is possible to bend a portion of the substrate defined by a given cutting line or cut in the direction of the substrate. by this,
At least part of the substrate (1.2) is released from the support material in the end region adjacent to the cutting line or the cut (1.4), thereby completely separating the substrate (1.2) from the support material (1.1). Provide a grabbing allowance (1.2).

This proposed problem solution facilitates the separation of adhesive substrates of this kind, but requires contact with the adhesive substrate by the finger, so that the finger of the active substance in the substrate may Contamination becomes possible.

DISCLOSURE OF THE INVENTION It avoids the above-mentioned disadvantages of the known solutions and adheres to a simple or reliable support or coating layer, but mechanically, without the risk or need for contamination of the contact or protected areas. It is an object of the present invention to provide a dosing aid that allows the removal of articles in a removable manner.

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

The use of the dosing aid according to the invention makes it possible, in each case, to have two characterized parts of the support material or coating layer with the article adhered to the support material or coating layer, i.e. only one article. Not only in some cases but also in the case where a plurality of articles are in a bonded state but are mechanically detachably connected to the support material or the coating layer, they are easily and reliably separated from the support material or the coating layer, This at the same time exposes certain parts of the protective surface of the article, without the need for or risk of manual contact, and with a part of the support or covering layer grasped by the hand of the article for its intended purpose. It enables easy and easy movement.

<Embodiment> Since the present invention is illustrated as an embodiment in the drawings, description will be added with reference to the drawings.

According to FIGS. 1 and 2, the article 2 shown in a circular cross-section is located on a rectangular support or covering layer 1, but the support or covering layer 1 and labels, plasters, medical systems, etc. The article 2 is in contact with each other or is opposed to each other in a mechanically detachable manner and is connected to each other at its contact surface.

Starting from the right end, the support or covering layer 1 is provided symmetrically with respect to an imaginary horizontal center line--a substantially triangular cut or a predetermined cut line 3. This cut or cut line 3 may be, for example, a notch or a perforation and extends over a portion of the thickness of the support or covering layer, this perforation being a slightly larger cross section with a number of perforations arranged a little closer together. Have. However, this cut or predetermined cut line is a slightly larger number of slightly longer indentations connected to each other by the web.
It may be in the form of. As a practical matter, it should be noted in this connection the fact that undesired premature cutting of the support or covering layer, for example during packaging, is sufficiently prevented.

Depending on the sensitivity of the contact surface of the article 2 to be protected, the cut or the predetermined cutting line 3 also penetrates completely in the thickness direction of the support material or covering layer 1 in the part extending below the article 2. It should be perforated or indented so that the web lies between them, as it does not, and in the regions extending out of the article 2. In any case, its formation should be chosen such that reliable protection of the surface to be protected of the article 2 is possible, but is determined by the cuts in the support or cover layer or the predetermined cut lines 3. The part 4 can be easily and completely separated from the support or cover layer 1 in a defined manner. As a practical matter in this regard, the area where the part 4 and the article 2 are interconnected is such that the article 2 has a support or coating when said part is separated from the rest of the support or coating. It must be ensured, respectively, that there is a complete separation between them and also a reliable adhesion to the part 4 of the article 2.

As is more apparent from FIG. 2, the hatched area 4a of the member 4 is large enough to provide a complete grip margin for separation of the support or covering layer 1 from the rest.

As a matter of fact, instead of the rectangle shown, any desired shape of support or covering layer can be implemented, and the same applies for the article 2, for example instead of circular articles in each case. Other arbitrary shapes can be selected according to Similarly, the shape of the member 4 may be appropriate and may be completely different from that shown in the drawings if necessary. Finally, the central position arrangement of the articles 2 on the support or cover layer 1 is also meant to be an example only, and the eccentric or asymmetrical arrangement of the articles 2 and the arrangement shape of the members 4 can be selected. .

Such an asymmetrical arrangement of the members 4 with respect to the support or cover layer 1 and in particular with respect to the article 2 is shown in FIG. 3, where the cut or the predetermined cut line is in the region where the member 4 is asymmetrically shaped. It moves upward at the right end so as to contact the article 2.

Depending on the environment, this asymmetrical arrangement and shape is transferred to the place where the article 2 is to be dispensed without contacting the contact surface of the article by the separating area which covers part of the article 2 and which projects from the article by the portion 4a. When administered to
It may be suitable to facilitate the use or administration of the article 2. For this purpose, the exposed surface of the article is first fixed at the dosing site, then the separating part 4 of the support or covering layer 1 is separated and finally the article is brought into full contact with the dosing site. In this case, the active substance-containing part or the surface of the article prepared for any other purpose must not be touched by a finger or any other device such as tweezers.

In order to facilitate the separating or separating operation, the gripping area 4a of the member 4 is provided with a projection or knob 5 which ensures a perfect grip in particular. Certainly, instead of the knob, a groove or other kind of depression may be provided.

FIG. 5 shows an example in which a considerable number of articles 2 or a part thereof are arranged or applied on a common support material or coating layer. As a matter of fact, here again the support material or covering layer 1 and the symmetrical shape of the arrangement and shape of the article 2 and that of the cut or predetermined cut line 3 and the tear portion 4 formed by the cut or predetermined cut line. And the contact portion 4a is not limited,
In addition, any suitable or desired shape may be put into practical use as long as there are no defects.

It goes without saying that the description and the examples given in the specification are for the purpose of illustration only and are not intended to limit the invention, and that other embodiments are implied by a person skilled in the art within the spirit and scope of the invention. is there.
