Definitions

• the present invention relates to a packaging, in particular blister packaging, with at least one cavity for receiving a liquid according to the preamble of claim 1.
• the present invention relates to the inclusion of a liquid in a package, in particular in a blister pack.
• the liquid is taken up in a cavity of the package.
• the following description is therefore directed in particular to a blister pack or to a blister for receiving a liquid, even if the present invention is not limited thereto, but preferably also in other liquid packaging can be used.
• a typical blister pack usually has two foils, which in turn may be constructed of several layers of different or the same materials.
• the films are usually made of plastic and / or metal, e.g. Aluminum, wherein other materials, such as paper or the like, in principle or additionally can be used.
• the two films are, in particular, a bottom layer or base film (carrier) and a cover layer or cover film (cover).
• one or more troughs or depressions for receiving the liquid may be formed, in which the liquid, in particular a pharmaceutical formulation, is filled.
• CONFIRMATION COPY Cover film or the cover is then placed on the bottom film or the carrier and fixed thereto or connected thereto, for example, at the edge locations or in a connection region, in particular flat surface areas, preferably by gluing, heat sealing, welding or the like he follows.
• DE 103 43 668 AI discloses a particularly dense blister packaging for pharmaceuticals, wherein the filling of the blister pack is not discussed in more detail.
• the present invention is particularly concerned with a complete filling of a cavity of a package, in particular blister pack, with a liquid.
• a gas or air bubble-free filling allows or facilitated.
• Such a complete filling is necessary, for example, when a blister pack is applied to a medical cartridge or assembly (for example, a so-called biosensor) and the liquid filled into the cavity of the blister pack, in particular with one or more reagents, has a certain detection reaction in the cartridge trigger or enable.
• the cartridge will then usually have a microfluidic system. So that a detection reaction aimed at by the liquid is not falsified or influenced, it may also be necessary for the liquid to be transferred to the cartridge without gas or air bubbles after opening the cavity.
• the present invention has for its object to provide a package, in particular a blister pack, with a cavity for receiving a liquid, wherein a complete filling of the cavity, in particular a B listers, with the liquid and / or a dense closing of the cavity facilitates or allows will or will be.
• the packaging has a capillary stop for the liquid.
• the capillary stop is arranged between the cavity and a connection region or in the connection region in which the bottom film or the support on the one hand and the cover film or the cover on the other hand are connected or connectable to one another.
• the purpose of the capillary stop is to prevent or at least limit or reduce flow or diffusion of the liquid from the cavity between the carrier and the lid or the formation of a liquid film, in particular in flat surface areas of the carrier and the lid.
• the recess is normally first covered by the lid or the cover sheet (loose) and then there is a connection of the lid to the carrier, in particular in the flat alsratilie - ing surface areas or in the connection area. It was possible to deduce from experiments that the liquid can flow or diffuse into the gap between cover and carrier in the surface areas lying on one another, in particular by capillary forces, namely into the imaginary connection region or beyond. This can lead to no (sufficiently) good or a non-full-surface connection of lid and carrier in the connection area in conventional packaging is achieved. The capillary stop now ensures that the liquid is prevented from flowing into the connection area.
• the proposed solution or the capillary stop assists a secure or tight connection of the cover and the carrier in the connection region or in which it adjoins the capillary stop outside. connecting area. Consequently, the proposed solution or the capillary stop supports a complete filling of the package or the cavity with liquid. Namely, the capillary stop also prevents liquid from undesirably flowing out of the cavity in an undesired manner from the cavity after filling, in particular by the capillary action of the superimposed surface areas of the lid and carrier, before a final closing of the packaging or the cavity or of the blister takes place ,
• capillary stop is to be understood in the present invention, in particular in general terms a means that prevents further flow of the liquid by capillary forces.
• the capillary stop is formed by a particular abrupt increase in the cross-section to be flowed through by the liquid.
• the capillary stop is particularly preferably formed by a depression in the carrier and / or in the lid.
