  • the DE 197 42 890 A1 describes a dispenser for receiving and dispensing products of all kinds without the use of propellants.
  • the dispenser consists essentially of a bellows container for receiving the contents, one or more spring packs, a lock in the lower area and a cover in the upper area.
  • the US 2004/0182867 A1 relates to a pressure compensating device for a double container, which consists of a diffusion-tight outer container and a collapsible inner container.
  • the inner container contains a liquid.
  • WO 2009/109370 A1 a metering device for metered dispensing of liquid preparations, in particular for metering of medical, pharmaceutical and cosmetic liquid preparations, wherein the use of preservatives can be dispensed with.
  • a reservoir for liquids or for viscous or sprayable products is provided, which is connectable to a metering device, wherein the reservoir is cylindrical and has a bottom with a pressure compensation device and an opposite open side, wherein the open side comprises a connection region, wherein a Pump head is attached to the reservoir via the connection area.
  • a collapsible by suction inner bag is arranged in the reservoir.
  • the inner bag is formed by a foldable bellows in the axial direction, at least one fold of the bellows, a contact device, which is in contact with the inner wall of the reservoir, arranged.
  • the contact device is formed integrally with the at least one fold or as a separate component and connected to the at least one fold.
  • the collapsible inner bag ensures that the liquid or the viscous or sprayable products can be completely removed from the reservoir. Furthermore, this inner bag is another barrier, since this inner bag is located in the cylinder-shaped reservoir and thus a double hedge contained in the inner bag Liquid is guaranteed. Such a reservoir thus has a higher density than the known from the prior art reservoir.
  • the inner bag is formed by a foldable in the axial direction bellows.
  • a bellows is characterized in that the inner bag has at least one circumferential fold, which represents a predetermined point at which the fold bag collapses during the emptying process.
  • the foldable bellows in the axial direction has at least one fold on a contact device which is in contact with the inner wall of the reservoir.
  • the contact device may be formed as an integral part of the bellows or as an additional separate component.
  • the contact device then consists of the same material as the bellows and can also be used in the manufacture of the bellows be formed.
  • a contact device is present as a separate component, and this separate component is then connected to the top of the fold.
  • the tip preferably has a corresponding device (eg groove) which receives the ring.
  • the device is designed so that only the ring touches the container inner surface. In the simplest case, this can be realized for example by an elastic rubber ring.

Likewise, the possibility is included in that the contact device is arranged on the bellows bottom and on one or more or all folds. From the material side, basically all materials for the formation of the contact device can be used, as they are also used for the production of a bellows. The materials of the bellows are described in more detail below.
  • a further embodiment of the present invention proposes that a spring is arranged to additionally support the movement of the bellows, this spring being arranged either in the intermediate space between the inner wall of the reservoir and the outside of the bellows and / or on the other hand that the spring inside the bag, between the connection area and the bottom of the bellows is provided.

This construction allows complete removal of the liquid. By allowing the bellows to be made very thin in terms of material thickness (e.g., 0.1 to 0.25 mm material thickness), material is saved.
  • the material of the inner bag is preferably selected from the group consisting of thermoplastic, elastomer, silicone, thermoplastic elastomer and mixtures thereof, for example low-density polyethylene as thermoplastic.
