Abstract
A dispenser system for a pumpable dispensed product, in particular a cosmetic fluid dispensed product such as a washing lotion, a cream lotion, a perfume liquid or similar includes a rigid or pliable product container and a dispensing device with a pump apparatus. The pump apparatus includes at least one first valve group for conveying the dispensed product out of the product container. The pump apparatus includes a second valve group for feeding air into the product container, wherein the second valve group defines a feed duct in which at least one filter unit for filtering sterile air is arranged. In subsidiary aspect, a filter unit for the dispenser system as well as a manufacturing facility and a manufacturing method for the manufacture of the dispenser system are provided.

Dispenser system for a pumpable product, comprising a rigid or pliable product container and a dispensing device with a pump apparatus, wherein the pump apparatus comprises at least one first valve group for conveying the product out of the product container, as well as a second valve group for feeding air into the product container, wherein the second valve group defines a feed duct in which at least one filter unit for filtering sterile air is arranged and wherein the pump apparatus is arranged to introduce a volumetric quantity of sterile air into the product container that is greater than the volumetric quantity of the product to be supplied, so that a positive pressure of sterile air is settable in the product container by sterile air, wherein the pump apparatus is designed as a manually operable double-pump apparatus and comprises a double-piston system for simultaneous conveying of the product out of the product container via negative pressure and introduction of the sterile air into the product container via positive pressure, so that sterile air and product are conveyed simultaneously into and out of the product container by a single piston actuator.
Dispenser system for a pumpable product, comprising a rigid or pliable product container and a dispensing device with a pump apparatus, wherein the pump apparatus comprises at least one first valve group for conveying the product out of the product container, as well as a second valve group for feeding air into the product container, wherein the second valve group defines a feed duct in which at least one filter unit for filtering sterile air is arranged, so that a positive pressure of sterile air is settable in the product container, wherein the pump apparatus is designed as a manually operable double-pump apparatus and comprises a double-piston system for simultaneous conveying of the product and introduction of the sterile air, wherein the second valve group comprises at least two non-return valve units connected one after another in the feed duct, wherein the filter unit or a second filter unit is arranged between a first non-return valve unit and a second non-return valve unit or between the second non-return valve unit and a third non-return valve unit.
Manufacturing facility for the manufacture and filling of a dispenser system for a pumpable product, the dispenser system comprising a rigid or pliable product container and a dispensing device with a pump apparatus, wherein the pump apparatus comprises at least one first valve group for conveying the product out of the product container, as well as a second valve group for feeding air into the product container, wherein the second valve group defines a feed duct in which at least one filter unit for filtering sterile air is arranged, so that a positive pressure of sterile air is settable in the product container, wherein the pump apparatus is designed as a manually operable double-pump apparatus and comprises a double-piston system for simultaneous conveying of the product and introduction of the sterile air, the manufacturing facility comprising at least a raw material tank, a processing tank and a storage tank for manufacture of the product, as well as a filling station for filling the product into the product container and for connecting the product container to the pump apparatus in an airtight manner, wherein a supply of external air takes place through at least one sterile air pressure line to which at least one sterile air filtering apparatus is connected.
Method for the manufacture of a dispenser system for a pumpable product, the dispenser system comprising a rigid or pliable product container and a dispensing device with a pump apparatus, wherein the pump apparatus comprises at least one first valve group for conveying the product out of the product container, as well as a second valve group for feeding air into the product container, wherein the second valve group defines a feed duct in which at least one filter unit for filtering sterile air is arranged, so that a positive pressure of sterile air is settable in the product container, wherein the pump apparatus is designed as a manually operable double-pump apparatus and comprises a double-piston system for simultaneous conveying of the product and introduction of the sterile air, comprising:
- S1:
- providing raw material under cover of sterile air;
- S2:
- processing the raw material to create product under the cover of sterile air;
- S3:
- storing the product under the cover of sterile air;
- S4:
- filling the product into the dispenser system under the cover of sterile air.
