Abstract

The pump has an one-way valve (4) opened by low pressure developed in a bottle (11), so that air flows through an air inlet (2), a vent pipe (9) and a pipe (1) in the bottle. The air inlet is provided in direct proximity of an outlet opening (10) in an ideal manner, so that the sucked air is disinfected by an output medium i.e. disinfectant, before inflow of the air into the bottle. The air inlet lies indirectly besides sealing edges (3) between an upper pump body with an inlet valve (5) and a bellows pump (6). The pump is used for evacuated bottles and for ventilated bottles.

Description

Die Erfindung betrifft eine Pumpe für flüssige, pastöse oder aufschäumbare Hautreinigungs- und Pflegepräparate, z. B. für Desinfektionsmittel zur Aufnahme durch eine Spendereinrichtung.The invention relates to a pump for liquid, pasty or foamable skin cleansing and care preparations, for. B. for disinfectant for inclusion by a dispenser.

Die nachfolgend beschriebene Wegwerfpumpe besitzt die Möglichkeit, die in der Spendervorrichtung eingesetzte Flasche mit dem Präparat entweder zu belüften, was bei nicht kollabierbaren Flaschen erforderlich ist, oder zu evakuieren, was bei kollabierbaren Flaschen erforderlich ist.The disposable pump described below has the ability to either aerate the bottle used in the dispenser device with the preparation, which is required for non-collapsible bottles, or to evacuate what is required for collapsible bottles.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine Wegwerfpumpe bereitzustellen, die sowohl für kollabierbare als auch für nicht kollabierbare Flaschen eingesetzt werden kann, so dass die Spendereinrichtung unabhängig von dem durch den Hersteller vorgegebenen Flaschentyp verwendet werden kann.The object underlying the invention is to provide a disposable pump that can be used for both collapsible and non-collapsible bottles, so that the dispensing device can be used regardless of the bottle type specified by the manufacturer.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass nachfolgend dargestellte Pumpe sowohl evakuierend als auch belüftend pumpt. Die Pumpe besitzt ein Entlüftungsstutzen, an dessen freiem Ende entweder ein Ventil zur Entlüftung angebracht ist oder ein dichter Stopfen für die evakuierenden Flaschen. Das Ventil der belüftenden Pumpe ist als Einwegeventil ausgelegt, so dass nur Luft in die Flasche strömen kann, aber kein Präparat durch das Steigrohr nach außen gelangt. Zwischen Entlüftungsstutzen und Ventil kann bei Bedarf ein Rohr angebracht werden, das verhindert, dass bei Desinfektionsmitteln die angesaugte Luft durch das in der Flasche befindliche Medium strömt. Hierdurch wird die Gefahr der Verkeimung des Mediums verringert.The object is achieved in that pump below pumping both evacuating and ventilating. The pump has a bleed port with either a vent valve attached to its free end or a sealed stopper for the evacuated bottles. The valve of the ventilating pump is designed as a one-way valve, so that only air can flow into the bottle, but no preparation passes through the riser to the outside. If necessary, a pipe can be installed between the vent pipe and the valve to prevent the intake of air in the case of disinfectants from flowing through the medium in the bottle. As a result, the risk of microbial contamination of the medium is reduced.

Ein weiterer Vorteil der beschriebenen Erfindung ist bei der Verwendung mit Desinfektionsmitteln, dass sich der Lufteinlass des Steigrohrs direkt neben der Auslassöffnung befindet, wodurch bei der belüftenden Variante die angesaugte Luft durch die Desinfektionsmitteldämpfe desinfiziert wird. Dadurch verringert sich die Gefahr einer Verkeimung des Flascheninhalts.A further advantage of the described invention, when used with disinfectants, is that the air inlet of the riser pipe is located directly next to the outlet opening, whereby in the ventilating variant the sucked-in air is disinfected by the disinfectant vapors. This reduces the risk of bacterial contamination of the bottle contents.

Anhand der Zeichnungen wird die Erfindung nachstehend beispielhaft näher erläutert.With reference to the drawings, the invention will be explained in more detail below by way of example.

1 zeigt in der Schnittdarstellung die Wegwerfpumpe. 1 shows in the sectional view of the disposable pump.

Durch die Betätigung der Faltenbalgpumpe (6) wird das in der Flasche (11) befindliche Medium durch den unteren Pumpenkörper mit Auslassventil (7) ausgegeben.By actuating the bellows pump ( 6 ) in the bottle ( 11 ) located medium through the lower pump body with exhaust valve ( 7 ).

Durch den dann in der Flasche (11) entstehende Unterdruck öffnet sich das Einwegeventil (4) und Luft kann durch den Lufteinlass (2), den Entlüftungsstutzen (9) und das optional vorhandene Rohr (1) in die Flasche (11) strömen. Die Luft strömt so lange nach, bis der Unterdruck in der Flasche (11) soweit ausgeglichen ist, dass sich das Einwegeventil (4) wieder schließt.By then in the bottle ( 11 ) resulting negative pressure opens the one-way valve ( 4 ) and air can pass through the air inlet ( 2 ), the vent pipe ( 9 ) and the optional pipe ( 1 ) in the bottle ( 11 ) stream. The air continues to flow until the vacuum in the bottle ( 11 ) is balanced so far that the one-way valve ( 4 ) closes again.

Der Lufteinlass (2) befindet sich idealerweise in unmittelbarer Nähe der Auslassöffnung (10). Dadurch wird die angesaugte Luft durch das ausgegebene Medium, insbesondere wenn es sich hierbei um ein Desinfektionsmittel handelt, vor dem Einströmen in die Flasche (11) desinfiziert. Der Lufteinlass (2) liegt daher unmittelbar neben den Dichtkanten (3) zwischen dem oberen Pumpenkörper mit Einlassventil (5) und der Faltenbalgpumpe (6).The air intake ( 2 ) is ideally located in the immediate vicinity of the outlet ( 10 ). As a result, the sucked in air by the dispensed medium, especially if it is a disinfectant, before flowing into the bottle ( 11 ) disinfected. The air intake ( 2 ) lies directly next to the sealing edges ( 3 ) between the upper pump body with inlet valve ( 5 ) and the bellows pump ( 6 ).

Die Wegwerfpumpe kann ebenso mit einer Flasche (11) eingesetzt werden, die evakuierend ausgeführt ist. In diesem Fall wird der beim Ausgeben des Mediums entstehende Unterdruck durch ein Zusammenfalten der Flasche kompensiert. Zur Verwendung der Wegwerfpumpe mit einer evakuierenden Flasche wird das optionale Rohr (9) und das Einwegeventil (4) durch einen Stopfen ersetzt, der auf den Entlüftungsstutzen (9) aufgesetzt wird und diesen luftdicht verschließt.The disposable pump can also be used with a bottle ( 11 ) are used, which is carried out evacuating. In this case, the negative pressure created when dispensing the medium is compensated by folding the bottle. To use the disposable pump with an evacuating bottle, the optional tube ( 9 ) and the one-way valve ( 4 ) replaced by a stopper on the vent ( 9 ) is placed and this hermetically sealed.
