Definitions

  • the invention relates to a container closure with a drying agent chamber filled with a hygroscopic drying agent, which has an opening in its area facing the inside of the container, which opening is closed by a cover plate enclosing the drying agent in the drying agent chamber.
  • stopper closures with a desiccant chamber have been developed predominantly made of plastic, in which the desiccant contained in the desiccant chamber is prevented from escaping by a cover disk, which is usually made of cardboard or cardboard is held in the container, being used by the porosity Cardboard material ensures that the air contained in the container is kept largely dry due to the hygroscopic property of the drying agent.
  • the size of the drying agent chamber and the amount of the drying agent used are chosen so that the drying effect is maintained during normal use of the preparation until it is completely used up under normal conditions.
  • Such plastic sealing plugs with a drying agent chamber eg DE-PS 36 22 773 have been proven for a long time.
  • the invention is based on the object of designing container closures with drying agent chambers in such a way that the drying effect of the drying agent enclosed in the drying chamber is ensured even under unfavorable circumstances, whereby used plastic closures should be reusable as easily as possible.
  • the risk of introducing microbiological contaminants into the container through non-sterile cover disks is to be largely reduced.
  • the cover plate is made of a plastic sintered material.
  • a plastic sintered material During sintering, particles are bonded at a sintering temperature that is usually close to the melting point, sometimes with additional pressure to produce workpieces or semi-finished products, such as strip material.
  • Such sintered materials have a porosity, the pore size being adjustable to a certain extent by appropriate control of the temperature and / or the action of pressure during the sintering process.
  • the use of plastic sintered material makes it easier to reuse the material from used closures, since there is no cardboard residue.
  • cover plate can, if desired, also be connected to the open mouth of the drying agent chamber of the container closure by means of a welding method suitable for connecting plastics, such as ultrasound or friction welding, which significantly improves the appearance of the connecting seam between the cover plate and the mouth of the drying agent chamber.
  • a welding method suitable for connecting plastics such as ultrasound or friction welding
  • cover plates made of cardboard material the thermal transfer of the edge of the Mouth of the drying agent chamber around the edge of the cover plate by means of a heated die can - alternatively - continue to be used.
  • Cover plates made of plastic sintered material also offer advantages with regard to sterile manufacture and processing, so that they are also preferable from a hygienic point of view.
  • the cover plates are expediently punched out of sintered plastic band material.
  • the plastic tape material can then be used in the form of rolls cut to the appropriate width in the desiccant filling machines used today, which previously worked with rolls of cardboard material from which the cardboard disks are punched out.
  • the material of the cover disks is set by appropriate guidance of the temperatures acting during the sintering process and / or - if appropriate - the pressing or rolling forces such that the pores remaining between the sintered plastic particles prevent water vapor from passing through or gas-permitting cross-sectional size, but preventing the passage of water or other liquid. Then the penetration and wetting of the cover disks with water is also ruled out if the closure as a whole falls into a water- or liquid-filled container. After simply wiping off any liquid droplets still adhering, the closure can then continue to be used without impairing its drying capacity.
  • cover disks from a plastic strip material which is produced from an ultra-high-molecular polyethylene using the strip sintering process.
  • the cover disks preferably have a thickness in the range between 0.7 and 1.0 mm.
  • the shown in the drawing figure, designated 10 container closure is a stopper closure made of plastic, which may be provided for closing tablet tubes or vials, the contents of which - at least during storage in the container - must be removed from the influence of atmospheric moisture.
  • the plastic sealing plug 10 has a base body made of plastic, which is composed of a closed end or handle plate 12 with an integrally molded hollow pin 14 which opens openly at its end opposite the handle plate 12.
  • the actual part of the stopper that can be inserted into the mouth of the tablet tube or vial forming high pin 14 is formed in the case shown as a so-called "sealing olive", ie has a spherical shape with a radially outward curvature in cross section, the maximum outside diameter being slightly larger than the inside diameter of the mouth of the container to be closed.
  • the hollow pin 14 When the hollow pin 14 is pressed into the mouth of the container to be closed, the hollow pin is thus compressed elastically and therefore lies tightly against the associated inner wall of the mouth of the container, so that the penetration of moist outside air into the closed container is definitely excluded .
  • an essentially cylindrical annular wall of smaller diameter 16 emerges from the grip plate 12, which still protrudes from the underside of the pin.
  • This ring wall 16 encloses a drying agent chamber 18 which is filled with a granular or granular drying agent 20 (e.g. silica gel or molecular sieve).
  • a drying agent 20 e.g. silica gel or molecular sieve.
  • the lower open end of the ring wall 16 facing away from the grip plate is closed by a cover disk 22 which, in the exemplary embodiment shown, is held in a known manner by thermal flanging of the lower edge of the ring wall 16 and thus prevents the drying agent 20 from escaping.
  • the cover plate 22 is formed here - in contrast to the porous plates made of cardboard material previously used for dry substance closures - by a suitable plate made of plastic sintered material. This cover plate is made by punching out sintered plastic band material.
  • cover disks which are punched out of ultra-high molecular weight polyethylene using the tape sintering process
  • the tape material being guided by appropriate guiding of the parameters acting during the sintering process, that is to say the temperature and / or the pressing or rolling forces possibly acting as well as the size of the plastic granules or powder used as the starting raw material, are set such that the pores remaining between the sintered plastic particles have sufficient permeability for the passage of gaseous gases Have substances or water vapor.
  • the pore size can also be set so that the passage of water or other liquids is prevented.
  • the plastic starting material used has hydrophobic properties inherently, ie does not allow liquids to flow away and soak up, but rather lets them drip off.
  • the hygroscopic properties of the desiccant in the desiccant chamber 18 are effective with respect to the water vapor contained in the container to be closed, i.e. dry the air trapped in the container and thus protect the container contents against the effects of water vapor, but that on the other hand there is an exhaustion of the hygroscopic properties to a much lesser extent than in the known closures with cardboard cover plates.
  • cover disks made of plastic sintered material is not limited to stopper closures, but can also be used for closures for flat packs in which the drying agent chamber has a shape that deviates from the cylindrical shape.
  • the cover disk is then only to be adapted in its limitation to the shape of the open side of the drying agent chamber.
