Description
- - 1 - 2(~25138 DESCRIPTION
Application aid for articles adhering in a mechanically removable manner to a carrier or covering layer of sheet-like form.
The present invention relates to an application aid for one Gr mGre articles, such as therapeutic systems, plasters, labels, or the like, positioned on a planiform extending, particularly flexible carrier or covering layer in an adhesive but mechanically releasable manner, in the form of cuts or predetermined breaking lines formed in the carrier or cGver layer.
Many ways of arranging articles adhesively on a base material, and for removing them if required are known. This, for example, can have the purpose of keeping the articles available in an easily accessible way. However, this is particularly useful, if specially prepared surfaces of articles are to be protected against any influence until they are applied.
For example, it is known to cover and protect the pressure-sensitive adhesive layer of labels, as well as plasters and other articles, by means of a removable protective foil until they are applied or used.
Removing the articles from a carrier layer or pulling-off the cover layer, to expose the area to be protected is particularly difficult if an adhesive composite between two materials is concerned. This particularly applies to those cases where the article surface to be protected is to be protected from damage and/or contamination bGth during and after exposure - 2U25 13&
by removing the carrier or cover layer, e.g., in order to maintain the adhesiveness of an adheslve layer, the intactness of sensltive surfaces agalnst mechanlcal lnfluences, a seal of the surface, e.g., against escape of volatile components applied to the surface, and so on.
Particularly if one tries to separate the partners by means of the fingernails, a knife, or any other lnstrument, undesired contact or even damage of the surface to be protected may occur. In additlon, it may happen that there ls no complete separatlon of the partners, i.e., portlons of the carrier or cover layer remain stuck to the surfaces to be protected, which then are very dlfflcult to remove from the surface wlthout damaglng it.
Such a procedure cannot be applied particularly lf the area to be protected is a sterile surface of a bandage, the skln contact layer of a therapeutlc plaster, or lf reactive materials, such as pharmaceutlc substances, are incorporated into the surface. These substances are applied topically and may contact the skin only at the site of application, for example, active substances for the treatment of actinic keratosis which are incorporated into a plaster system.
In order to solve the above-mentioned problems, it has been proposed to provide straight cuts or predetermined breaking lines in the carrier or covering layer, so that by flexing and/or pulling-off the carrler or cover layer, portlons of it can be removed from the article which is adhesively connected ~.~
_ 3 _ 2U2 5 t 38 -to said layer. However, perfect, complete and simple exposure of the surface of the article or a corresponding removal thereof, respectively, is not guaranteed, particularly if a sensitive article is concerned, such as, for example, a therapeutic plaster, a plastic moulding, a very flexible carrier or cover layer of a thin aluminum foil, an aluminum laminate, a polymer foil, or the like. Particularly in case of small articles having a small surface to be protected, it is difficult to expose it completely. But even the selective separation of individual sections of the article and carrier or cover layer has not been solved satisfactorily.
In U. S. Patent No. 3,230,649 the provision cf arcuate cuts or predetermined breaking lines in the carrier foil is described, which, on flexing the material, lead to a gripping tab of the carrier material so that this section can be peeled off. However, this solution does not provide a satisfactory process for co~,plete and undamaged separation of the partners connected with each other, since, in general, a remaining portion of the carrier layer must be laboriously removed from the article by means of the fingernails or an auxiliary tool.
It is also known, in the use of several articles or several connected parts cf an article, to ccnnect them by means of a kind of releasing tape so that, on pulling a projecting portion of the tape, the parts connected by this tape can be removed from the carrier layer in one operational step.
However, prior to use or application of the individual porticns they have to be released from the releasing tape. In addition 2U2513~
to the relatlvely expensive productlon, this known arrangement ls llmlted to the slmultaneous removal of several artlcles or several parts of an artlcle, and to relatlvely small artlcles or parts thereof. It is also known to provide strips or threads of suitable material, such as plastic, textiles, or metal, between a carrier layer and the articles posltioned thereon, whereby these strips or threads pro~ect at least at one end from the articles or parts thereof so that separation will be possible. However, this arrangement and the formation thereof involves considerable expense, not to mention the fact that it cannot be applied ln all cases.
A pulllng-off ald ls known, whlch ls intended for mechanically removable substrates (1.2) adhering to a planiform, flexible carrier material (l.1). It consists of non-linear cuts or predetermlned breaking lines (1.4) in the carrier material (1.1) for each indlvldual substrate (1.2).
By applylng pressure on the carrler material (1.1) in a vertical direction to the substrate contact surface, a portion of the substrate predetermined by the lines of the predetermined breaking lines or cuts is bendable in the direction of the substrate or substrates. In this way, at least a portion of the substrate (1.2) in its edge region ad~acent to the cut line or predetermined breaking line (1.4) is released from the carrier material (1.1) and thus provides a gripping section (1.3) at the substrate (1.2) in order to completely remove the substrate (1.2) from the carrier material (1.1).
The proposed solutlon of the problem permlts easy removal of such adheslve substrates, however, it also requlres contactlng the adheslve substrate area wlth the flngers so that contamlnation of the flngers with reactlve materlals ln the substrate becomes posslble.
It ls the ob~ect of the present lnventlon to provlde an appllcatlon aid avolding the above-mentioned dlsadvantages of the known solutlons and permlttlng removal of artlcles connected in an adheslve but mechanlcally releasable manner to a carrler or cover layer ln an easy and rellable way wlthout the necesslty or danger of contaminatlon of the contact or protectlve area.
Thls ob~ect ls achleved accordlng to the present lnventlon, whlch, broadly, resldes ln the comblnatlon of at least one artlcle selected from the group conslstlng of a therapeutlc system and therapeutlc device, and a removable carrier or covering layer, said article belng posltloned on and adherlng to sald carrler or coverlng layer, sald carrler or coverlng layer being substantlally flat and flexlble and ZO having integral therewith an application aid for said article, sald appllcatlon ald definlng a portlon of sald carrler or coverlng layer and being detachable therefrom by severlng guldes, sald artlcle belng so posltloned upon the carrler or covering layer such that a portlon of the artlcle ls posltloned over a part of the appllcatlon ald and the severing guldes.

Sultable further embodiments of the present lnvention are descrlbed hereln and ln the accompanying claims.
The use of the application aid according to the present lnventlon permlts a predetermined portlon of the carrler or cover layer wlth an artlcle adherlng thereto to be easlly and rellably separated from the carrler or cover layer where only one article, but also where a plurallty of artlcles, is connected to the carrler or cover layer ln an adheslve but mechanlcally removable manner. Thls ls accomplished wlthout the necesslty nor the danger of manual contact wlth the exposed surface of the artlcle to be protected, and thus permlts easy and comfortable transfer of the artlcle to lts lntended purpose by means of the portion of the carrier or coverlng layer grlpped by the hand.
The invention is illustrated ln the drawlng as embodlment examples, and will be further explalned wlth reference to the drawlngs, wherein Flgure 1 ls a plan vlew of a square carrler or coverlng layer wlth a clrcular article positioned thereon, Figure 2 ls a plan vlew of a sectlon of the carrler or cover layer whlch, together wlth the artlcle, has been separated from the carrier or cover layer according to Flgure 1, Figure 3 is a plan view of a modification of the carrler <,~ 28483-16 . ~
_ 7 _ 202~138 or cover layer of Figure 1, Figure 4 is a plan view of another modification of the carrier or cover layer of Figure 1, Figure 5 is a plan view of an embodiment comprising an arrangement of a multiplicity of articles on a common carrier or cover layer, respectively.
According to Figures 1 and 2 the article 2 illustrated with circular cross-section is centrally positioned on the square carrier or cover layer 1, whereby the carrier or covering layer 1 and the article 2, which may be a label, a plaster, a therapeutic system, or the like, are connected with each other at their contact surfaces either contacting or Gpposing each other in an adhesive but mechanically releasable way.
The carrier or cover layer 1, starting from its right-hand edge, is provided - relative to an imaginary horizontal center line, symmetrically - with the substantially triangular cut or predetermined breaking line 3. This cut or predetermined breaking line 3 may, for example, be a notch or perforation extending over a portion of the thickness of the carrier or covering layer, whereby the perforation may exhibit a more or less large number of more or less closely arranged perforation holes having a more or less large cross-section. However, this cut or predetermined breaking line could also have the form of a more or less large number of more or less long indentations connected with one another by webs. As a matter of fact, in this connection, it is ensured that the mechanical stability of the carrier or covering layer 1 is adequate to reliably prevent - 8 - 20~5138 unintentional and too early separation - for example during packaging.
Depending on the sensitivity of the contact surface to be protected of the article 2, one may also form the cut or predetermined breaking line 3 in the region where it extends below the article 2 as a notch not completely passing through the thickness of the carrier or cover layer 1, and in the regions extending outside of the article 2 as perforations or indents with webs lying in between. In any case, the formation is chosen in such a way that reliable protection of the surface to be protected of the article 2 is guaranteed, while that the portion 4 of the carrier or covering layer 1, which is determined by the cut or predetermined breaking line 3, can be separated easily and safely from the carrier or covering layer 1 in the defined way. In this connection it has to be ensured that the area, at which portion 4 and article 2 adhere to each other, is chGsen in such a way that both perfect removal of article 2 from the carrier or cover layer and the reliable adherence of article 2 to portion 4 is maintained when said portion is separated from the rest of the carrier or covering layer.
As is particularly obvious from Figure 2, the hatched region 4a of the member 4 is sufficiently large so as to permit safe gripping for separation from the remaining portion of the carrier or covering layer 1. Preferakly, the member 4 should overlap at least 10% of the area of the article 2.
As a matter of fact, any desired shape of the carrier or cover layer 1 can be realized instead of the square shape 9 2~25:13~9 shown. The same applies to the article 2, i.e., instead of the circular shape, any other possible shape may be chosen, depending on the article of the respective case. Similarly the shape of member 4 can be completely different from that as shown, just as is suitable or required. Finally, the central arrange-ment of the article 2 on the carrier or covering layer 1 is meant to be an example only; any other off-central or asymmetric arrangement of article 2 and arrangement and formation of member 4 could be chosen.
Such an asymmetrical arrangement of the part 4 in relation to the carrier or cover layer 1, and in particular to article 2, is shown in Figure 3 in which the cut or predetermined breaking line 3 is displaced upward at the right edge so that the member 4 contacts the article 2 on an asymmetrically shaped area.
According to the circumstances, this asymmetric arrangement and formation can be suitable to facilitate the use or application of the articles 2, if the article 2, by means of the separated member 4 covering Gne portion of the area of the article 2 and projecting the article 2 by part 4a, is transferred to the site of application and applied thereto without touching the contact surface of the article. For this purpose, the exposed surface of the article is at first anchGred to the site of application, then the separated part 4 of the carrier or cover layer 1 is removed, and finally the article is completely brought into contact with the site of application. In this connection the active-substance-containing or otherwise prepared 2t~2~
surface of the article never has to be touched with the fingers or any other auxiliary instrument, such as forceps or the like.
In order tc facilitate the separation or releasing process, respectively, the region 4a of the member 4 meant for gripping it with the hand, is provided with elevations or nobs 5, thus particularly ensuring safe gripping. Certainly, engravings or any other kind of elevations may also be provided for, instead of the nobs.
An example of arranging and applying several articles 2 or even parts of an article on a common carrier or covering layer is shown in Figure 5. As a matter of fact, in this case too, the symmetric shape of the carrier or cover layer 1, as well as the arrangement and form of the articles 2 and of the cut or predetermined breaking lines 3, and that of the tear-off portions 4 and gripping parts 4a formed by the cut or predetermined breaking lines are not compulsory. Any other suitable or desired form can be utilized without having to accept any disadvantages.
It is understood that the specification and examples are illustrative but not limitative of the present invention and that other embodiments within the spirit and scope of the invention will suggest themselves to those skilled in the art.

For this purpose, the exposed surface of the article is at first anchGred to the site of application, then the separated part 4 of the carrier or cover layer 1 is removed, and finally the article is completely brought into contact with the site of application. In this connection the active-substance-containing or otherwise prepared 2t~2~
surface of the article never has to be touched with the fingers or any other auxiliary instrument, such as forceps or the like.
In order tc facilitate the separation or releasing process, respectively, the region 4a of the member 4 meant for gripping it with the hand, is provided with elevations or nobs 5, thus particularly ensuring safe gripping. Certainly, engravings or any other kind of elevations may also be provided for, instead of the nobs.
An example of arranging and applying several articles 2 or even parts of an article on a common carrier or covering layer is shown in Figure 5. As a matter of fact, in this case too, the symmetric shape of the carrier or cover layer 1, as well as the arrangement and form of the articles 2 and of the cut or predetermined breaking lines 3, and that of the tear-off portions 4 and gripping parts 4a formed by the cut or predetermined breaking lines are not compulsory. Any other suitable or desired form can be utilized without having to accept any disadvantages.
It is understood that the specification and examples are illustrative but not limitative of the present invention and that other embodiments within the spirit and scope of the invention will suggest themselves to those skilled in the art.
