Definitions

  • the invention relates to a closable container for Dispensing viscous substances, such as creams, according to the generic term of claim 1.
  • a container of this type is known from DE 39 28 524 A1.
  • This container is coaxially movable with two Hollow piston provided, one of which on the Pump base and the other on one that runs out to a mouthpiece Actuation button sits.
  • the container equipped with a bellows through which the actuation button is axially resettable and that of a pump device up to the upper area of the first-mentioned hollow piston extends.
  • the bellows is provided with a piston ring that bears against the inside of the first-mentioned upper hollow piston.
  • the container is therefore unsuitable for dispensing substances to the highest requirements to the quality consistency, e.g. B. sterility, be put.
  • the German utility model 90 05 014.2 describes one Cream dispenser that is airtight only through a lid is closable because an inner lid has a dispensing opening has only through the lid separated from the container is lockable.
  • a secure closure Opening in the inner lid through the on the container attachable lid not guaranteed because of the Spilled opening on the top of the inner cover Cream in the between the cap and the Inner cover remaining space due to the contained therein Air experiences a quality impairment that does not meets all requirements for the quality of a cream and leads to loss of usable cream.
  • the delivery opening is blocked possible by curing the cream.
  • the invention has for its object a container of the aforementioned type, which, despite frequent removal of the preservatives contained therein free fabrics, the durability of these fabrics over a satisfactory maintained for a long period and by the at the same time a simple, dosed removal of the substance contained in the container is ensured.
  • the container according to the invention has an inner lid, which hermetically seals an upper opening of the container and by an operating device integrated in the inner cover and a co-operating, self-closing Check valve a removal of one in the container contained substance allowed without opening the container must become. This is achieved by means of overpressure of the pneumatically acting actuating device is generated in the container to open the self-closing Check valve leads and at the same time for an escape of the substance contained in the container the valve opening ensures. An air intake into the container is avoided. Thus, germs or bacteria, for example do not enter the container from the surroundings and the durability of the fabric it contains is not influence negatively.
  • By coupling pneumatic Actuator and self-closing check valve can dispense the contents of the container by pressing a finger be opened without the container and its Content must be damaged by air access.
  • the pneumatic actuation device from an outwardly convex or dome-like, form-elastic elevation of the inner cover with one opposite a lid base of the inner lid reduced wall thickness.
  • the pneumatic actuator enables them one-piece design with the inner cover.
