A process for continuously manufacturing transdermal therapeutic patches having a backing layer, a pressure-sensitive adhesive drug reservoir layer, and a removable protective layer, whereby loss of active substances during fabrication of the patches is minimized, said process being characterized in that, in a tape-like laminate having a pressure-sensitive adhesive backing layer (,) and a removable protective layer (,), single quadrangular pressure-sensitive adhesive drug reservoir sections (,) are inserted one after the other in the longitudinal direction between the layers (,); the clearance between said drug reservoir sections remains constant in the longitudinal direction; their width is calculated such that the backing layer (,) and the removable protective layer (,) project beyond both sides of said sections; the pressure-sensitive adhesive backing layer (,) is first cut by punching in such a way that the punching line (,) surrounds the individual drug reservoir sections (,) at an evident distance from their outer dimensions; the the resulting lattice-type refuse of the drug-free pressure-sensitive adhesive backing layer (,) is removed; and subsequently the protective layer (,) is cut in the resultant spaces between the drug reservoir sections (,).

Process for producing a flat active substance administration form

The present invention relates to a process for the production of collagen foams in the form of continuous tapes, characterized in that a) solved or dispersed collagen is cast into disk molds, b) the collagen solution or dispersion is frozen in the disk mold and subsequently is freeze-dried c) continuous tapes are produced from the freeze-dried disks by mechanical processes. Furthermore, the present invention relates to the use of said tapes so obtained in medicine, cosmetic and hygiene.

Process for the production of collagen foams in the form of continuous

The invention relates to a process for producing an administration and/or dosage form for medicament active substances using a printing process, in which the printing process used is a pad printing process.

Process for producing and administration and/or dosage form for

In combination, a bag, at least one active mass, and a support, the active mass being carried on the support within the bag and having an exposed pressure-sensitive adherent surface, the support carrying integral spacers which are laterally spaced from the active mass and project above the surface of the support a distance greater than the height of said active mass, thereby to space the mass from the bag.

The invention relates to a removal aid for mechanically detachable substrates adhering to a sheet-like, flexible carrier material and in the form of cuts or predetermined breaking lines in said carrier material. At least in the contact surface of the carrier material is provided for each substrate a separate, non-linear cutting or predetermined breaking line, so that when pressure is exerted on the carrier material with a force component in a direction at right angles to the substrate contact surface a carrier material portion with the substrate portion adhering thereto and bounded by the cutting or predetermined breaking line can be bent in the direction of the substrate or substrates, so that at least part of the substrate in the border area thereof adjacent to the cutting or predetermined breaking line is detached from the carrier material and consequently a gripping portion is formed on the substrate for the complete removal of the latter.

Removal aid and use thereof

The invention relates to plasters, particularly epicutaneous test plasters with at least one active substance absorbing or receiving device (14) arranged on a carrier film (32). The carrier film (12) is made from a highly elastic polymer material, which is impermeable for liquid water, but permeable for water vapour. On the surface remote from the skin, it is detachably connected in whole-area or partial area manner with a support film (11) at least covering the surface of the carrier film. The invention also relates to processes for the production thereof and the use thereof.

The invention is related to a foil- or film-like bandage consisting of a transparent continuous bandage foil which on the one side is covered with a transparent supporting foil and on the other side is provided with an adhesive layer and a removable cover layer thereupon, the supporting foil extending over said transparent continuous bandage foil at opposite edges and the cover layer having the same size as the adhesive layer, said cover layer having particularly formed preset cuts or preset breaking lines between two points at different edges, preferably opposite edges such that the cover layer is partitioned into two parts and, upon bending of the foil- or film-like bandage, there is produced an auxiliary pull-off means in the cover layer for the same.

Foil- or film-like bandage and process for using the same

The present invention is related to a flat laminate part consisting of a substrate layer and a cover layer having an auxiliary pull-off means to so pull-off said cover layer or parts of said cover layer said auxiliary pull-off means comprising a preset cut or cuts or a preset breaking line or lines in said cover layer, said auxiliary pull-off means being improved by having a stiffened area in the surrounding of the preset cuts or preset breaking lines in order to facilitate the producing of the grasp parts for pulling off said cover layer or parts of said cover layer.

Flat laminate part consisting of a substrate layer, a cover layer and an

The present invention is related to a flat laminate part consisting of a substrate layer and a cover layer the adhesive compounding between said substrate layer and said cover layer being such that both layers are securely held together, but a pull-off of said cover layer from said substrate layer is readily possible by hand or mechanically, said flat laminate part having additionally an auxiliary pull-off means to so pull-off said cover layer or parts of said cover layer by hand or mechanically along preset cuts or, respectively, preset breaking lines in said cover layer, wherein said preset cuts or preset breaking lines in said cover layer are positioned and formed such that there is at least one part of the cover layer which can be grasped per each part of said cover layer to be pulled off, said grasp part is, getting exposed by bending the flat laminate part getting exposed by bending the flat laminate part to form a concave curvature of the surface of said cover layer opposite to the surface of said cover layer adhearing to said substrate layer and that the two points of attack of the force producing such bending of the flat laiminate part are distributed over the surface of the flat laminate part such that the hand produced or mechanical pull-off forces acting substantially vertically to the laminate result in a peeling off of said grasp part of said cover layer.
