Definitions
- the invention relates to a container closure with a filled with a hygroscopic desiccant Desiccant chamber in the inside of the container facing area has an opening, which by a enclosing the desiccant in the desiccant chamber Cover plate is closed.
- Such dry matter closures are always used for closing of containers used if that's in the container Good to be filled due to changes in air humidity can experience the undesirable or inadmissible are.
- plug closures mainly made of plastic today with drying chamber, developed at which the desiccant contained in the desiccant chamber by one, today usually made of cardboard or cardboard existing cover plate against leakage into the container is maintained, being used by the porosity of the Cardboard material ensures that the contained in the container Air due to the hygroscopic nature of the Dry substance is kept largely dry.
- the size the desiccant chamber and the amount of desiccant used is chosen so that the drying effect during the normal period of taking the product until preserved under normal conditions remains.
- cover plates used from cardboard material Another disadvantageous aspect of the cover plates used from cardboard material is that plastic materials recycled today if possible should be, what also for plastic closures applies. For reusing plastic closures But with a dry matter chamber, it's not just a matter of distance of the dry matter, which is caused by crushing the closures and screening out the dry matter relatively easily is possible, but also the cardboard discs or sorted out the parts of the shredded cardboard disks will.
- the invention is based on the object, container closures to train with desiccant chambers so that the drying effect of the trapped in the drying chamber Desiccant even under unfavorable circumstances is guaranteed, used plastic closures can be easily reused should be. In addition, the risk of involvement microbiological impurities in the container non-sterile cover plates can be largely reduced.
- the cover plate made of a plastic sintered material is made.
- particles become in one sintering temperature mostly near the melting point, partly under additional pressure to generate of workpieces or semi-finished products, for example Band material, connected.
- Such sintered materials have a porosity, the pore size by appropriate Management of temperature and / or pressure To a certain extent adjustable during the sintering process is.
- the use of plastic sintered material facilitates the reuse of the material from used ones Closures, since cardboard remains do not accumulate.
- cover plates made of cardboard material the thermal flanging of the edge of the Mouth of the drying agent chamber around the edge of the cover plate by means of a heated die, alternatively - continue to be used. Also regarding cover plates are available for sterile manufacture and processing advantages of plastic sintered material, so that they are also preferable from a hygienic point of view.
- the cover disks are expediently made of sintered plastic strip material punched out.
- the plastic tape material can then be cut to the appropriate width Rolls in the desiccant filling machines used today used to date with roles Cardboard material work from which the cardboard discs are punched out will.
- the material of the cover plates by appropriate guidance during the sintering process acting temperatures and / or - if appropriate -
- the pressing or rolling forces is set so that between the sintered plastic particles remaining pores prevent the passage of water vapor or gas permitting the passage of water or one other liquid, however, prevents cross-sectional size to have. Then the penetration and wetting of the cover plates excluded with water even if the closure overall in a water or liquid filled Container falls. After simply wiping the the liquid droplet still adhering is the closure then continue without affecting its drying capacity usable.
- a production of the cover disks has proven to be particularly advantageous made out of a plastic band material, which is made of an ultra high molecular weight polyethylene is produced in the band sintering process.
- the cover disks preferably have a thickness (Thickness) in the range between 0.7 and 1.0 mm.
- the invention is connected in the following description explained in more detail with the drawing, which is a plastic sealing plug with a drying chamber in the so-called Half section shows that for the closure of the Inclusion of pharmaceutical preparations in certain containers is provided.
- the one shown in the drawing figure, designated 10 Container closure is a plastic plug closure, the one for closing tablet tubes or vials may be provided whose contents - at least during the Storage in the container - the influence of humidity must be withdrawn.
- the plastic plug 10 has a base made of plastic, which consists of a closed end or handle plate 12 with a integrally molded hollow pin 14, the end of the handle plate 12 opposite openly opens.
- the actual, in the mouth of the Tablet tube or vial insertable stopper part forming high pin 14 is in the case shown so-called "sealing olive” formed, i.e. has one in cross section radially convex domed shape, the maximum outer diameter slightly larger than the inside diameter Inner diameter of the mouth of the container to be closed is measured.
- a substantially cylindrical annular wall Diameter 16 Within the hollow pin part 14 comes from the handle plate 12 a substantially cylindrical annular wall Diameter 16 before that still from the bottom of the Protrudes.
- This ring wall 16 encloses a drying agent chamber 18 with a granular or granular Dry substance 20 (e.g. silica gel or molecular sieve) is filled.
- a drying agent chamber 18 with a granular or granular Dry substance 20 (e.g. silica gel or molecular sieve) is filled.
- the lower open facing away from the grip plate The end of the ring wall 16 is closed by a cover disk 22, which in the illustrated embodiment in known manner by thermal flanging the lower Edge of the annular wall 16 is held and so the exit of the Prevents drying agent 20.
- the cover 22 is here - different from those previously porous washers used in dry-type closures made of cardboard - from a matching disc made of plastic sintered material educated. This cover is by punching out sintered plastic band material produced.
- Cover panes have been proven to be made using the band sintering process are punched out of ultra high molecular weight polyethylene, whereby the tape material by appropriate guidance of the parameters acting during the sintering process, i.e. the temperature and / or the press or if applicable Rolling forces as well as the size of the raw material used plastic granules or powder set so is that between the sintered plastic particles remaining pores a sufficient permeability for the passage of gaseous substances or Have water vapor.
- the pore size can also be set so that the passage of water or other liquids is prevented.
- the plastic raw material used inherently has hydrophobic properties, i.e. liquids not let it flow away and soak it up, but roll off leaves.
