Dosing device for/to a

Bottles containing cleaning fluid

The invention relates to a dispenser for bottles containing a cleaning liquid, which is made of one piece from plastic and can be screwed onto the bottle neck, with a dosing and pouring head in which there is a central, closed-end dosing tube with at least one spray hole, into which a riser tube is inserted which is immersed in the cleaning liquid and conveys the cleaning liquid into the dosing tube and the dosing and pouring pot when pressure is applied to the bottle, and with a closure lid which is hinged to the dosing and pouring head and which reaches over the dosing tube with a nozzle and closes the spray hole.

In a dispenser of this type, which has become known in practice, the spray hole(s) in the dosing tube are arranged in an unfavorable manner, since when pressure is applied to the bottle, the liquid sprays out of the dosing tube across, hits the pot casing and sprays upwards out of the open dosing and pouring pot.

If the bottle is handled improperly, i.e. if too much pressure is applied to the bottle, this spraying effect

increased, so that a portion of fluid is constantly lost.

The object of the invention is to improve a dispenser constructed according to the type mentioned at the beginning in a simple manner so that the liquid to be dosed is collected perfectly in the dosing and pouring pot and cannot splash out of the pot.

This object is achieved according to the invention by the characterizing features of claim 1.

The subsequent subclaims contain design features which represent advantageous and beneficial further developments in the solution of the task.

The dispenser according to the invention is equipped with spray holes in its dosing tube that are arranged diagonally downwards and outwards, through which the liquid to be dosed is collected in the pot in a perfect manner, since it is sprayed diagonally downwards towards the bottom of the pot and thus cannot spray upwards out of the open pot.

Even if you press harder and suddenly on the bottle and the liquid pressure increases, the liquid will always spray downwards into the pot and thus there will be no loss of escaping liquid.

The spray holes are designed to spray downwards as steeply as possible, depending on the tool-specific possibilities.

The drawing shows an embodiment of the invention, which is explained in more detail below. It shows:

Fig. 1 a longitudinal section through a cleaning agent bottle with dispenser,

Fig. 2 shows a longitudinal section through the dosing device in an enlarged view.

The dispenser for a cleaning liquid (2), such as detergent, glass and floor cleaner, toilet cleaner or similar containing bottles (1) made of dimensionally stable and deformable plastic is made in one piece from at least translucent, preferably transparent plastic.

The dispenser has a dosing and pouring pot (4) with a screw sleeve (5) molded onto the bottom, with which the dispenser can be removably attached to the bottle neck (3) by screwing it on.

The dosing and pouring pot (4) is extended at its pot base (6) to form a pot part (7) that projects into the bottle neck (3) so that the screw sleeve (5) extends around it.

In the dosing and pouring pot (4) there is a central dosing tube (8), which is molded onto the pot part (7) at its lower end and has a closed front end (9).

A riser pipe (10) is inserted into this dosing pipe (8), which is immersed in the cleaning liquid and reaches almost to the bottom of the bottle.

In the dosing tube (8), a spray hole (11) is provided in the tube wall at a distance from the closed front end (9), which is arranged in such a way that it results in a spray angle (α) directed in the direction of the pot base (6) and pot shell (12) for the liquid emerging from the dosing tube (8).

Preferably, at a distance from the closed front end (9) in the metering tube (8) on this circumference, two or more spray holes (11) are cut out, which are directed obliquely downwards and outwards and are at an acute angle (α) to the longitudinal axis of the metering tube (8).

A closure lid (13) is hinged to the dosing and pouring pot (4) by means of a material hinge (14), which closes the open side of the pot and, with a molded-on nozzle (15), reaches over the dosing tube (8) and also closes its spray holes (11) (Fig. 1).

To remove the cleaning liquid (2) in measured amounts, the closure cap (13) is opened as shown in Fig. 2, then pressure is exerted on the bottle (1) by hand and a certain amount of bottle deformation is carried out, whereby the liquid (2) rises up in the riser pipe (10) and sprays out of the spray hole(s) (11) of the dosing pipe (8) and due to the slanted (steeply downward-pointing) spray holes (11) the liquid (2) sprays downward and cannot spray out of the open pot (4) at the top.

The liquid (2) collects in the dosing and pouring pot (4) and the desired amount of liquid can then be read from markings (16) on the pot casing (12). The dosed amount of liquid is then poured out of the pot (4) and the dosing device is closed with the cover (13).

In Fig. 2, the closed front end (9) of the metering tube (8) is shown as a point pointing obliquely upwards (oblique front end). Preferably, however, this front end (9) is designed as a central point with rounding in the manner of a bullet tip, as shown in Fig. 2 in dash-dotted line, whereby a simplified tube closure is achieved by means of the closure cover nozzle (15).

Claims (3)

Protection claims 1. Dispenser for bottles containing cleaning liquid, which is made in one piece from plastic and can be screwed onto the bottle neck, with a dosing and pouring head in which there is a central, closed-end dosing tube with at least one spray hole, into which a riser tube is inserted which is immersed in the cleaning liquid and conveys the cleaning liquid into the dosing tube and the dosing and pouring pot when pressure is applied to the bottle, and with a closure lid hinged to the dosing and pouring head, which reaches over the dosing tube with a nozzle and closes the spray hole, characterized in that the spray hole (11) is arranged in the dosing tube wall in such a way that it results in a spray angle (α) directed towards the pot base (6) and pot jacket (12) for the liquid (2) emerging from the dosing tube (8). 2. Dosing device according to claim 1, characterized in that at a distance from the closed front end (9) in the dosing tube (8) on the circumference of which two or more spray holes (11) are cut out, directed obliquely downwards and outwards. 3. Dosing device according to claim 1 or 2, characterized in that the spray holes (11) are aligned with the longitudinal axis of the dosing tube (8) are at an acute angle (α).
