Benefits of technology

"The patent describes a dispenser for media, such as skincare products, that can be used with a one-piece receiving container. The receiving container has a dispensing chamber and a storage chamber that can be exchanged. The container is made of elastic material and has a dosing member that acts upon the dispensing chamber to dispense the media. The receiving container can be a bag made of plastic material, which can be welded together. The dispenser does not require a separate valve or pump member, reducing costs and the risk of clogging. A self-closing outlet member is also provided. A retaining member prevents the medium from being urged back into the storage chamber, ensuring a predefined amount of medium is dispensed. The retaining member can be mechanically coupled with the dosing member. A conveying member is provided for conveying the medium from the storage chamber into the dispensing chamber, ensuring an adequate amount of medium is available."

Problems solved by technology

However, this has the drawback that the receiving container must be cleaned at regular intervals for preventing germ formation.
This type of dispenser is also disadvantageous in that germ formation may occur in the pump region.
Further, both types of dispenser have the drawback that clumped-together dry media may clog up the pump.
This is a laborious procedure.
Further, an exchange of the pump or a pump valve is cost-intensive since this component is comparably expensive.
In particular, pasty media additionally containing cleansing particles may lead to frequent clogging of the pump or a pump valve.
Although provision of a vent reduces the generation of a negative pressure after a dosing process and improves the medium flow, this is however an inadequate measure when pasty media in particular with a viscosity of more than 80,000 mPa are involved.
Further, the dispenser described in DE 690 01 302 T2 has the drawback that in particular media containing particles, such as abrasive particles, tend to clog up the valve region.
Consequently, the valve region must frequently be cleaned or exchanged, wherein in this case an exchange involves considerable costs due to the complexly configured valve bottom comprising an additional air inlet.

Embodiment Construction

[0028]The dispenser arranged in a housing not shown comprises an elastic receiving container 10, in particular configured as a plastic bag, which is adapted to be suspended or fixed in the housing preferably via holding fixtures. The receiving container comprises a storage chamber 12 filled with media. Further, the receiving container 10 comprises a dispensing chamber 14 connected with the storage chamber 12. At an end of the dispensing chamber 14, which is the lower end in FIG. 2, an outlet 16 is provided through which the medium can be urged out. In the region of the outlet 16 an outlet member 18, serving as a valve, for example, may be arranged, said outlet member being made of the same material as the receiving container 10.

[0029]For defining the dispensing chamber 14, the corners of the receiving container 10, which are the lower corners is FIG. 1, are respectively separated by a weld 15 shown in dashed lines such that the volume of the dispensing chamber 14 is reduced. Further...

Abstract

A dispenser, which is in particular suitable for pasty media, comprises an elastic receiving container for receiving the medium. The receiving container comprises a dispensing chamber and a storage chamber. Further, a dosing member is provided which acts upon the dispensing chamber. In particular with a view to cost reduction, the receiving container is of one-piece configuration and comprises both the dispensing chamber and the storage chamber.

Description

BACKGROUND[0001]1. Field of the Disclosure[0002]The disclosure relates to a dispenser for media, in particular skin cleansers, skin protection products and skin care products. In particular, the dispenser is suitable for pasty media, wherein the media may preferably comprise cleansing particles.[0003]2. Discussion of the Background Art[0004]Known dispensers for media and the like comprise a manually operable pump for conveying media out of a receiving container. The receiving container is refillable, for example. However, this has the drawback that the receiving container must be cleaned at regular intervals for preventing germ formation. Further, it is known to provide an exchangeable receiving container which is connected with the pump of a dispenser. This type of dispenser is also disadvantageous in that germ formation may occur in the pump region. Further, both types of dispenser have the drawback that clumped-together dry media may clog up the pump. It is thus necessary to clea...
