Definitions

• the invention relates to a device of the type mentioned in the preamble of claim 1 and its use.
• the production and use of flat pressure-sensitive adhesive substrate sections is known. After they have been produced, there is a need to protect the substrate sections from the loss of active ingredient, for example as a result of evaporation, for the period of their storage until use.
• the active substance-containing, self-adhesive substrate sections are sealed after a protective covering of their pressure-sensitive adhesive surface by a removable carrier or protective layer in a pouch enclosing them on all sides from a material impermeable to the vapor phase.
• the backing layer preferably projects above the pressure-sensitive adhesive surface, which makes it easier to pull off the backing or protective layer.
• EP 0 405 393 describes a device for increasing the storage stability of flat substrate sections which are packed in pouches and are provided with a pressure-sensitive adhesive, the pressure-sensitive adhesive surface of which is protected by a carrier layer which at least partially projects beyond it. Spacer elevations are arranged in this, on the carrier layer, as a spacer between the carrier layer and the bag.
• a rapid wound dressing which consists of a carrier strip provided with a pressure-sensitive adhesive layer, a wound dressing thereon for immediate covering of the wound in the form of a pillow-shaped structure made of gauze, cellulose, non-woven fabric or similar material, and one there is arranged protective layer.
• This is designed as a flat piece that can be divided along a predetermined line. This division line is formed by weakening the material, such as perforation or incisions.
• the invention is based on the object of specifying a device for increasing the storage stability of substrate sections packed in bags, provided with a pressure-sensitive adhesive layer, of the type mentioned in the preamble of claim 1, which can also be used for comparatively long storage despite the cold flow of the pressure-sensitive adhesive harmful bonding of the sub- avoids strats with packaging surfaces of the bag and enables unhindered, problem-free removal of the substrate from the package, which is only open on one side, for use.
• elevations designed as spacers are arranged on the opposite side thereof.
• the spacers arranged on both sides of the carrier layer according to the invention give the advantage, on the one hand, of a very uncomplicated type of packaging, and, on the other hand, reliably prevent sticking between the substrate and the packaging, even when sandwich-like laminates are stored for a relatively long time with an amorphous, cold-flow adhesive layer between two solid layers.
• a detachment aid in the form of an incision or perforation in the carrier layer is present as a weakening line
• the present invention eliminates the acute risk of gluing between the packaging material and the adjacent packaging material easily and with simple means if, according to the invention, there are spaced elevations along the cutting or weakening line are.
• FIGURE 1 a perspective view of a laminate comprising a substrate with a pressure sensitive adhesive coating Layering and carrier layer arranged thereon, but without packaging;
• FIGURE 2 in longitudinal section along a plane AA perpendicular to the surface of the substrate, a laminate with substrate including adhesive layer and carrier layer laminated thereon, but with packaging.
• the device shown in FIGS. 1 and 2 for increasing the storage stability of substrate sections (4) packaged in bags (3) according to FIG. 2 and provided with a pressure-sensitive adhesive layer (5) is provided with a carrier layer (6) that at least partially overhangs the pressure-sensitive adhesive layer (5) ) protected from gluing with the packing material in that in the protruding area on the side assigned to the substrate section (4) elevations (1) fixed on or formed from it are arranged as spacers with respect to the bag (3).
• the carrier layer (6) has a line of weakness (7), for example in the form of an incision or perforation, as a release aid to facilitate the carrier layer (6) to be detached from the pressure-sensitive adhesive layer (5), the risk of the carrier layer (6) sticking together must be avoided
• Material of the packaging bag (3) can be countered by pressure-sensitive adhesive emerging in a cold flow with a device design suitable for this purpose. According to the invention, this is achieved in that, in addition to the elevations (1) on the side of the carrier layer (6) assigned to the substrate section (4), elevations (2) designed as spacers are arranged on the opposite side.
• the carrier layer (6) has at least two partial areas (6 ') or (6 ") forming a common cutting or weakening line (7) between them, and that in addition to the cutting or weakening line (7) spacing surveys (2) are available.
• the exemplary configurations shown in FIGS. 1 and 2 provide a laminate comprising a substrate section (4) with a pressure-sensitive adhesive coating (5) which is covered with a carrier layer (6). At the areas protruding from the substrate (4), edge-shaped elevations (1) are formed, which in height (H) project beyond the substrate section (4).
• the carrier layer (6) has a line of weakness or detachment aid in the form of a cut or perforation (7) through which pressure-sensitive adhesive material escapes in a cold flow during long-term storage and thereby an adhesive bond between the carrier material or its underside with the material of the packing bag (3 ) could cause.
• a line of weakness or detachment aid in the form of a cut or perforation (7) through which pressure-sensitive adhesive material escapes in a cold flow during long-term storage and thereby an adhesive bond between the carrier material or its underside with the material of the packing bag (3 ) could cause.
• the most endangered surface areas (6 ') or (6 ") of the carrier layer (6) on the underside thereof are protected from sticking by elevations (2) along the weakening line (7) by elevations (2) arranged next to and offset from one another .
• FIGS. 1 and 2 provide that the elevations (1, 2) preferably consist of hot-melt polymers which can advantageously be easily deformed and have no stickiness at room temperatures of up to approximately 50 ° C.
• the use of the device according to the invention is particularly advantageously suitable for packaging plasters, therapeutic systems and other substrates which have a coating with pressure-sensitive adhesive, in particular planar substrates.
• the invention is extremely expedient and optimally achieves the object stated at the outset.
