Description
132~3~2 The invention relates to a primary pack of surface-stabilized bandaging materials, which has a carrier layer and a skin-side contact surface having contact adhesive areas. The contact surface is protected prior to use of the bandaging material by a removable covering layer. An at least one-layer supporting or backing ~ilm is detachably applied to the carrier layer surface remote from the skin and is removable from the applied bandaging material after fulfilling its function lG of surface stabilizing the carrier layer.
Bandaging materials can be subdivided into two major groups. The first group consists of those whiGh are fixed at the point of their application by additional devices or measures, while the other group involves fixing by contaot adhesive areas of the actual bandaging material. In the case of the latter group, the requirement for thin and flexible carrier layers ensuring a usa~le moisture resistance and good close adaptability to the contours of the application point have led in the ~0 past to difficulties during application. Thus, after removing the covering layer, there can occur, for example, rolling in of the marginal regions, stic~ing together of Gontact adhesive areas and creasing, which makes the bandaging material unusable.
As described in West German OLS 1935916, an improvement i8 attainable by the use of a so-called supporting or backing film for surface stabilization purposes, a more rigid layer than the carrier layer being so connected thereto that it can be detached following application. This principle has proved satisfactory in practice (cf. West German Patent No . 33 44 334 ) .
However, it must be regarded as disadvantageous that the supporting film is discarded after removal from the applied bandaging material and consequently its function is limited ts surface stabilization. The expenditure involved in providing the material and the manufacturing measures for this additional element of such bandaging materials is not inconsiderable.
.; ~
~2~3~2 An objeGt of the present invention is therefore to permit çxtension the function of the supporting film so that the cost/use ratio becomes more favorable.
Accordingly, the invention provides a primary pack for surface-stabilized banda~ing material, which comprises a carrier layer, a skin-side contaGt surface with contao~ adhesive areas, the sontact surface being protected by a removable covering layer prior to use of the bandaging material, and an at least one-layer supporting film detachably applied to the skin-remote carrier layer surface and whiGh i5 removable from the applied bandaging material, the supporting film being part of the pack protecting the bandaging material.
Thus, the problem is solved by a primary pack of the aforementioned type in which the supporting film is part of the pack protecting the bandaging material. In the sense of the invention, the term "primary pack" is intended to mean a protective layer directly enveloping the bandaging material. The thus packed individual pieces can be combined into larger units by secondary and tertiary packs. The actual protection of the substrate is mainly ensured by the primary pack.
The invention is usable in all bandaging materials ffurface-stabilized by supporting films. These bandaging materials are known and are used, for example, as wound bandages, f~xing bandages, active substance-delivering plaster and incision film~ or foils. The carrier layer of the bandaging material can, for example, be a textile material, a polymer material or a metal-containing layer. The supporting film is constituted by an at least one-layer flat structure of materials containing polymers, paper or metal. Its surface has at least the same extension as the carrier layer, but accordiny to a preferred embodiment of the invention can pro~ect on one or more sides over the carrier layer edge.
The detachable Gonnection between the supporting film and the carrier layer can be produced by known methods, such as producing the carrier layer directly on the supporting 3 ~32~
film, heat sealing, welding, bonding, embossing or forming electrostatic attraction forces.
The materials for producing the contact adhesive areas ensuring ~ontact with the skin may be cho~en from the vast number of possibilities satisfying the standpoint of phy~iologiGal non-objectionability. A removable covering layer protects the skin contact surfaGe of the bandaging material prior to use.
The purpose of a primary pack for such a bandaging material are known to those skilled in the art.
The hitherto known solution of introducing the bandaging material as a whole into an envelope surrounding same on all side~, followed by bonding, sealing, welding or embo~sing of all the edges has not proven ~ati~factory due to the type of material which had to be used.
According to the invention, one surface of the primary pac~ is formed by the supporting film to the top or bottom surface of which is fixed in the marginal area the surface structure forming the remainder of the pack.
Fixing can take place, for example, by heat sealing, welding, embossing or bond~ng. If the supporting film has the ~ame surface area as the carrier layer, the remaining pack components are fixed to the top surface of the ~upporting film. If the supporting film pro~ects over the carrier layer, it may be preferable to provide the fixing to the bottom of the pro~ecting parts of the supporting film.
After tearing open the bag-like primary pack, the supporting film remains on the back of the carrier layer, which ensures the desired stabilization of the bandaging ~aterial during application.
The fixing of the remaining flat packing material to the supporting film and the production of the detachable connection between the s~pporting film and carrier layer Gan take place in one step according to the invention.
The choice of the remaining flat packing mater1al is determined by the partlcular requirements of ,~
. .
~2~2 the band~ging material to be packed. Generally, apart from materials containing impermeable paper, polymers or metals, consideration can by given, for example, to those materials which, on the basis of their structure, can be S looked upon as textile fabrics. The material choice for . the supporting film and the remaining pack need not be the same, but ~ust be matched to the particular re~uirements.
In conventional manner, the pack can be provided with a tear-open aid, such as tearing threads, desired breaking lines or the like.
In a particularly preferred embodiment of the invention, the bandaging material contains at least one ; aGtive substance. It can be a transdermal therapeutic system, in which an individual pack is unavoidable.
~mbodiments of the invention will now be described in greater detail and by way of example with reference to the accompanying drawings, in which:
Figure 1 is a diagrammatic cross-section through an embodiment of a packed bandaging material; and Figure 2 is a diagrammatic cross-section through another embodiment of packed bandaging material.
As shown in Figure 1, a carrier layer 4 formed from textile material is coated with a contact adhesive layer 5, which can contain a pharmacologically active substance. On the skin-facing side a covering layer 6, is provided which is here made from paper adhesively finished by siliconization. A supporting film 7 cover~
and projects from the carrier layer 4 on all sides and is made from a multilayer film material more rigid than the carrier layer. It is connected to the carrier layer 4 by heat sealing at points 8 distributed in accordance with a predetermined pattern. During heat sealing, a sealing edge 11 is formed with a packing film 10 located below it.
Figure 2 shows another preferred embodiment of the invention in which the supporting film 7 is of the same size as the carrier layer. The packing film 10 surrounds the bandaging material and is bonded at the edges to ~he top of the supporting film 7. In this case ~32~352 the contact adhesive layer 5 has no separate covering layer and instead the packing film 10 assumes the function o. protective layer. The bandaging material can be applied directly after opening the pack.
A preferred embodiment of the inventive ~! bandaging material is described hereinafter relative to an example.
Ex~m~le Production of a packed bandaging material was - 10 effected, in which part of the pack functions as a supporting film.
A 15 x 20 cm2 bandaging material consisting of a textile carrier layer and an active substance-containing contact adhesive layer applied thereto was placed ,, 15 centrally between two heat sealable packing material portions projecting by approximately 1.5 cm on each side.
The packing material was chosen in such a way that the portion coming into contact with the carrier layer could ; assume the function of the supporting film. Edge sealing and the detachable connection of the supporting film to the carrier layer was performed in one or two successive stages. The finished sealing edge bag was then assembled - in the usual way.
