Release strip with partible break to facilitate removal of adhesive coated strip

FIELD OF THE INVENTION

The present invention relates to laminated structures comprising adhesive coated strips, on release strip are attached, and in particular such structures, the release strip exhibit by means which coated the removal of adhesive Strip easier.

BACKGROUND THE INVENTION

coated with adhesive strips, as labels, bandages, dermal patches and the like, are common. In front the application to a desired surface by a user, the adhesive coated strip generally with an adhesive coating, which against pollution or the inadvertent attachment to itself or to an undesirable Protects surface from a certain kind of treated release paper or plastic release film provided, the or below the detachment strip referred to as. Before use, the user separates the release strip of the adhesive coated strip, whereby the adhesive coating exposed. The strip is then for the intended application the adhesive strip provided. Separating the adhesive-coated Strip from the release strip but can be a frustrating process and can damage the lead coated with adhesive strip, particularly at the edges, where the user attempts to start the separation, typically by fingernail or a sharp instrument used. This is common in pressure-sensitive adhesive products of the case, such as labels and more recently, self-adhesive stamps. The type and Ease of detaching the strip from Abreißmaterial is often a function of the state of the user's fingernails.

In situations in which a given coated with adhesive strips stiffer than its adhesive release tab is the release strip may close bent sharply at the edge of the adhesive coated strip are, thereby causing the edge of the adhesive coated strip from the release strip separates. A user can then the exposed edge of the adhesive take the coated strip and its separation from the release strip continue.

However, it often happens that the detachment strip is stiffer than the adhesive coated strip. to this encounter problem, add the Manufacturers of some coated with adhesive strip means, the separation of the adhesive coated strip from the release strip to facilitate. Ordinary binding for household have two release strip from plastic or coated paper, both the adhesive portion as well as cover the Gazeabschnitt the napkin. Overlap the two release liner typically near the center of the napkin over the Gazeabschnitt where no is or much less adhesive available. The release strip can be further provided with tabs to detecting the ends of release tab to further facilitate the user's finger. The user is thus able to detect the inner end of the release strip and separate them from the binding to these z. B. at a wound site apply.

Another means used is to the removal of an adhesive coated strip by a release strip facilitate, is editing the release strip so that he break lines contains. This technique is common with pressure sensitive adhesive labels. Around remove the label from the provided with fracture lines release strip, folds a user from the laminate coated with adhesive Strips and peel strips to a specified rupture line, thereby causing the release strip along specified line breaks, whereby the edges of the release strip extending, the user then can take to the detachment strip further decrease of the pressure-sensitive adhesive label.

Other applications of adhesive coated strips wherein the adhesive coating comprises a relatively thick viscous and tacky gel have been introduced into common use. Such applications include, for. Example, skin patches, electrocardiogram electrodes and Teeth whitening strips. Such strips are for convenience preferably thin Movies so they adapt to the mounting surface. This provides a special challenge for the removal of such adhesive coated strips from their respective release strip represent.

Another issue is the question the disposal of the remaining release liner. In the case of agents that removing the adhesive coated strip from the release strip facilitate, often arise several pieces the release strip, some of which may be small be and easily overlooked can. It should be understood that in medical environments and with oral applications, the number of Parts and the physical size of the remaining release tab represent an important problem. It is preferable the number to reduce of such parts, and to avoid small pieces.

It is a simple, inexpensive Means needed the removal of the adhesive coated strip from the release strip relieved with the release strip is used to the adhesive coating prior to application of to protect the coated with adhesive strip, z. B. a bandage, a skin patch or a teeth whitening strips, the release strip after removal of the adhesive coated strip <?page 3?>one-piece remains. It is also necessary that the means for facilitating doffing an adhesive coated. Strip from its adhering release strip effective implementation processes relevant are.

It is therefore an object of the the present invention to provide an improved release strip at the removal of an adhesive coated strip is facilitated, said release strip after removal of the adhesive coated strip remains in one piece.

SUMMARY THE INVENTION
