Definitions
- the invention is directed to a device which is capable of reducing the moisture content or to ensure a defined moisture content of a closed gas space surrounding the device, to a method for producing such a device and to the use of this device
- drying devices are known in the prior art. These can be desiccant-filled containers which are used, for example, for the dry storage of moisture-sensitive products
- a desiccant bag is known, which is commercially available from Multiform Dessicant Ine, (Buffalo, New York) under the name Desimax TM.
- This type of desiccant bag consists of two bag walls that enclose an interior by means of weld seams on the edge of the bag walls. This interior contains a certain amount of
- Desiccant namely 4 A molecular sieve
- the bag walls themselves are at least partially permeable to water vapor
- the disadvantage of such a system is that the certain, limited amount of the desiccant inside the bag corresponds only to a certain, limited moisture absorption capacity. If the amount of the desiccant is exhausted due to reaching the maximum absorption capacity for moisture (i.e. essentially water), the remains Desiccant bag ineffective Further moisture or water absorption is impossible and the guarantee of a constant, in particular reduced humidity in one Enclosed gas space surrounding the desiccant bag is not possible.
- the desiccant bags are also not very versatile in terms of their usability with regard to different drying needs, because the amount of desiccant per bag (and thus the maximum moisture or water absorption capacity) is limited by the interior volume.
- These packaging containing desiccants are multi-layer laminates.
- a layer containing desiccant can be attached to the composite of the other layers of the laminate using an adhesive layer.
- this packaging is subject to the rapid exhaustion of the moisture or water absorption capacity in the event of prolonged contact with normal ambient air. Normal ambient air means air that does not have a reduced relative humidity, but at least 40% relative humidity.
- Normal ambient air means air that does not have a reduced relative humidity, but at least 40% relative humidity.
- the processing of these packaging laminates therefore also requires process steps in a room that is sealed off from the environment and / or work in a room with reduced air humidity.
- the object of the invention is therefore to provide a device for reducing the moisture content of a closed gas space surrounding the device or for setting a defined relative air humidity, which avoids these disadvantages of the drying devices known in the prior art.
- the need for processing or prior storage in a closed gas space surrounding the device with reduced moisture content or processing under extremely time-limited conditions should be avoided.
- the object is achieved by a drying device which contains a matrix with a desiccant contained therein and can be activated under technically sensible conditions. If necessary, the
- Drying device contain a layer permeable to water vapor. With this layer the matrix can, if necessary, directly be covered.
- the desiccant is a regenerable desiccant.
- the drying device according to the invention and in particular the desiccant-containing matrix are preferably sheet-like.
- the drying agent-containing matrix of the drying device has or is a pressure-sensitive adhesive layer.
- Matrix in the sense of the invention means a carrier for the desiccant.
- inorganic and organic materials, in particular polymeric materials are suitable as materials for this matrix.
- the matrix materials must have the ability to allow water molecules to penetrate and migrate within the material. On the other hand, this entering water must not lead to a complete dissolution of the polymeric material.
- Materials such as: polymeric substances such as acrylates, silicones, polyisobutylenes, SIS rubber, SBS rubber, SEBS rubber, polyvinylpyrrolidone, polyurethane, polyester, polyethylene, polyvinyl alcohol, polyamides, ethyl vinyl acetate, polyacrylic acid, collidon (copolymers of vinyl acetate and Vinyl pyrrolidone) and cellulose derivatives.
- polymeric substances such as acrylates, silicones, polyisobutylenes, SIS rubber, SBS rubber, SEBS rubber, polyvinylpyrrolidone, polyurethane, polyester, polyethylene, polyvinyl alcohol, polyamides, ethyl vinyl acetate, polyacrylic acid, collidon (copolymers of vinyl acetate and Vinyl pyrrolidone) and cellulose derivatives.
- All film-forming materials can be used. Mixtures of the organic polymer materials mentioned can of course also be used.
- the matrix is free of active pharmaceutical ingredients.
- the matrix is preferably sheet-like. This means that the spatial configuration of this matrix in the three dimensions (height,
- the height of the sheet-like matrix has a minimum value of approximately 50 ⁇ m and a maximum value of approximately 3 mm; the height of the sheet-like matrix is preferably between 200 and 500 ⁇ m.
- the width or length of the sheet-like matrix are not critical parameters, but can meet the respective needs of practice be adjusted.
- the minimum value of the width for a practical handling of the sheet-like matrix can be seen as approximately 2 mm.
- the width of the sheet-like matrix is preferably between approximately 1 and approximately 50 cm, particularly preferably between approximately 2 and approximately 10 cm.
- the length of the sheet-like matrix can also be theoretically infinite. However, preferred lengths are also between about 1 and about 50 cm, particularly preferably between about 2 and about 10 cm, because of the easier handling.
- the desiccant-containing matrix is elastic, which means the ability that the matrix can show a reversible change in shape. This improves certain properties of the matrix, such as softness, flexibility, flexibility and workability. It is necessary to add substances to the matrix that can influence this property.
- substances include plasticizers (elasticizers, plasticizers) for the respective matrix materials.
- plasticizers are, for example, polyethylene glycol, polypropylene glycol, glycerol, miglyol, propanediol, triglycide, esters such as diethyl phthalate, tributyl citrate, etc., which are optionally added to the matrix in such amounts until the desired elasticity is achieved.
- the desiccant-containing matrix can be pressure-sensitive, which means the ability that the matrix is permanently connected to a surface with a certain pressure by pressing it once. For this it may be necessary to add substances to the matrix that influence this property.
- substances include tackifiers (tackifiers, adhesive resins). Suitable tackifiers are known to the person skilled in the art, for example:
- Rosin esters and hydrogenated esters of rosin, hydrocarbon resins, etc. which are optionally added to the matrix in such amounts until the desired pressure-sensitive adhesive property is achieved.
- the special matrix materials must be taken into account when choosing the amount of tackifier. The others can do this too
- Components of the matrix containing the desiccant have an influence on the adhesive properties, so that no exact limits for the quantitative proportions can be specified.
- the amount ranges are therefore generally between about 5 and 70% tackifier in the matrix.
- Quantities of about 10 to 30% tackifier are preferably contained in the matrix (based on the total weight of the matrix).
- the drying device in the embodiment in which the drying device contains a pressure-sensitive adhesive layer or even the desiccant-containing matrix itself is pressure-sensitive, expediently contains a release liner with an adhesive finish, which covers this pressure-sensitive adhesive layer and from which the drying device is removed before use.
- the materials for such carrier layers are known to the person skilled in the art, for example they can be foils containing substances such as polyethylene terephthalate, polyethylene, polypropylene, paper and their modifications.
- the drying device can additionally contain a layer which is permeable to water vapor.
- the matrix can optionally be covered with this layer.
- Layer can be on one side or on both sides of the sheet-like matrix.
- suitable materials for such water vapor permeable protective layer come z.
- the drying device can also contain a support layer. It has the purpose of giving the drying device a higher dimensional stability. This can be the case, for example, when the matrix containing the desiccant is itself too flexible for practical handling, for example due to its very small thickness or relatively high elasticity.
- the support layer can optionally cover the matrix or even be identical to the layer permeable to water vapor.
- the support layer can be located on one side or on both sides of the sheet-like matrix. Suitable materials for such a support layer are materials known to the person skilled in the art, for example PET film, polyethylene, polypropylene, paper, nonwovens, etc.
- the drying device can also contain a protective layer which protects the desiccant matrix against mechanical stress from the outside, e.g. B. to protect abrasion or against leakage of desiccant. If necessary, this layer can be identical to the layer permeable to water vapor and / or the support layer. Suitable materials for the protective layer are materials known to the person skilled in the art, for example plastics such as polyethylene, polypropylene, paper, nonwovens, etc.
- the drying device prefferably contains a layer which fulfills at least two of the technical functions of a water vapor permeable layer, support layer and protective layer.
- the desiccant-containing matrix can also be a
- Moisture indicator included the color of which depends on the water content and which thus indicates whether it is contained in the matrix Desiccant is still capable of further absorption of water.
- moisture indicators include, for example, copper (II) or cobalt (II) salts such as. B. CuSO or CoCI 2 in question.
- Desiccant in the sense of the invention means a substance that can absorb moisture, but especially water.
- the ability of these substances to absorb moisture can be based on a chemical or physical effect.
- regenerable substances are suitable for the invention, that is to say substances which are capable of releasing absorbed moisture (for example water) under certain conditions and thereby changing into a state which enables the substance to absorb moisture again.
- Suitable regenerable drying agents are CaSO (calcium sulfate, anhydrous gypsum, anhydrite), CaSO 4 • 1/2 H 2 O (hemihydrate), CaCl 2 , Al 2 O 3 , CaO, Na 2 SO 4 , K 2 C0 3 , CuSO 4 , Mg (CIO 4 ) 2 , MgSO 4 , silica gel (blue gel,
- Silica gel silica gel
- PVP polyvinyl pyrrolidone
- these substances are used as solids or as a solution.
- the physical form does not play a special role, crystals, powders, amorphous solids, granules, rubbings, etc. come into question.
- the size of these solids in the desiccant is limited by the requirements for the thickness of the sheet-like matrix.
- An upper limit for the size of the solid particles is therefore approximately 200 ⁇ m, but particles with a grain size below 50 ⁇ m are preferably used.
- the minimum grain size of these particles is 1 ⁇ m.
- the content of the desiccant in the matrix depends primarily on the desired moisture or water absorption capacity of the respective drying device and on the moisture or
- Water absorption capacity of the special desiccant used For example, if only a low water absorption capacity is required, the use of a desiccant with a low water absorption capacity in a low content in the desiccant matrix may be sufficient.
- a low desiccant content (in active form) in the matrix for example, could represent about 0.5 to 5% of the total weight of the desiccant matrix.
- the thickness and the area of the desiccant-containing matrix can then possibly even be at the respective lower limits.
- a desiccant-containing matrix with a relatively high desiccant content must be used, whereby the desiccant should also have a high water absorption capacity.
- Such a high desiccant content in active form) can make up, for example, about 50 to 70% of the total weight of the desiccant matrix.
- the drying device as such can be activated.
- the object as a whole, but in particular, of course, the desiccant matrix is stable to the conditions under which the desiccant contained in the matrix is regenerated.
- the actual activation of the drying device or the desiccant-containing matrix can take place in various ways.
- the simplest type of activation is to store the desiccant-containing matrix under elevated temperature (for example 105, 110, 120, 140 or 170 ° C) for a certain period of time.
- elevated temperature for example 105, 110, 120, 140 or 170 ° C
- the required one Storage duration the shorter the higher the selected temperature.
- Other options for activation can be the use of infrared radiation or microwave radiation.
- Example: 0.2 atm and / or an artificially generated circulating air facilitate the selected activation conditions (for example: temperature, duration, radiation intensity).
- the use of these additional measures can also result in the fact that, in the case of activation at elevated temperature, this does not have to be above 100 ° C., the boiling point of the water under normal conditions, but may already be around 60 to 80 ° C.
- the regenerable desiccant When activated, the regenerable desiccant changes into its active form, in which it has the ability to absorb moisture or water.
- the activation method which can also consist of a combination of different activation methods and additional measures, on the materials present in the drying device or in the matrix containing the drying agent and their properties (sensitivity to infrared or microwave radiation or increased Temperatures) must be taken into account. Otherwise, the materials of the desiccant matrix or the drying device may have to be adapted to the required activation conditions. The economy of the activation method and the material costs of the drying device may also need to be coordinated.
- a desiccant-containing matrix are flat-shaped systems, which include, for example, labels, films, tapes, rolls, stickers or discs.
- the advantages of the drying device according to the invention are, inter alia, that the desired moisture or water absorption capacity of the drying device by simply calculating its area and, if appropriate, its thickness and
- Concentration of the desiccant in the matrix can be adapted to the particular need. This is due to the fact that the water absorption capacity of the drying device, with constant thickness and constant concentration of the drying agent in the matrix, is generally linearly related to its area. If the water absorption capacity of a drying device used is exhausted, further drying requirements could be supplemented by simply adding a further, easy-to-calculate area of the drying device according to the invention.
- the drying device according to the invention is used to reduce the moisture content of a closed gas space surrounding the device or to maintain a defined, preferably reduced moisture content in a closed gas space surrounding the device. It can therefore be used in a method for reducing the moisture content of a closed gas space surrounding the device or for maintaining a defined, preferably reduced, moisture content in a closed gas space surrounding the device.
- This gas space must be sealed gas-tight, so that there can be no exchange with air and the ambient air humidity contained therein.
- closed gas spaces can be, for example, airtight packaging of products.
- the possibilities for using the drying device according to the invention can therefore be found in the field of packaging moisture-sensitive objects, such as, for example, food, pharmaceuticals, diagnostics, medicines, moisture-sensitive chemicals, and biologically activatable material. It is preferred to use drying devices according to the invention within packaging for tablets, transdermal therapeutic systems and sheet-like pharmaceutical dosage forms for oral use.
- drying agent contained in the matrix has the ability to molecules other than water (such as organic solvents such as ethanol, methanol, etc., odorants such as acetaldehyde, acetic acid etc., gaseous substances such as CS 2 , NH 3 , H 2 S, etc. .) to bind, one use may be to reduce the content of such molecules in the gas space surrounding the drying device, or to keep this gas space largely free of such molecules.
- molecules other than water such as organic solvents such as ethanol, methanol, etc., odorants such as acetaldehyde, acetic acid etc., gaseous substances such as CS 2 , NH 3 , H 2 S, etc. .
