Description

introduction

The invention relates to the field of extraction devices. In particular, the invention relates to a withdrawal device for liquid media with an exchangeable reservoir.

State of the art and disadvantages

Dispensing devices for liquid media serve to dispense liquids in portions, such as those for cleaning surfaces or the body. Dispensers of various shapes and sizes are known for this purpose. For portioning, mechanical pressure is applied to a dispenser head with one hand. A certain amount of liquid then flows out of the dispenser head, which is either caught by hand or a cleaning cloth, or applied directly to the surface to be cleaned.

It is often problematic that the entire removal device is displaced when the dispenser head is actuated. In particular, on surfaces that are tiled or made of ceramic (bathroom, kitchen), it is likely that the removal device will slip or even fall down.

Object of the invention and solution

The invention is therefore based on the object of providing a device which avoids the disadvantages of the prior art. Accordingly, the removal device should remain at a predetermined location even in the case of mechanical actuation by means of compressive force.

The object is solved by a device according to claim 1. Advantageous embodiments can be found in the dependent subclaims, the following description and the figures.

description

The removal device is used for portioned removal of a cleaning liquid from a reservoir. The portions are typically in the milliliter range; the cleaning liquid can have a dynamic viscosity from water to honey (approx. 1 to 10,000 mPa·s).

The reservoir is designed as a bottle-like container and has, in particular, a cylindrical shape, or it has a rectangular basic shape. The content of the container is preferably 50 to 2000 ml, preferably 100 to 1000 ml, and particularly preferably about 200 to 500 ml.

The removal device further comprises a dispenser head, which can be connected to an end of the reservoir on the dispenser head side. In other words, the dispensing head and reservoir can be attached to each other. When mechanical pressure is applied, the dispenser head serves to dispense the cleaning liquid in portions. The pressure is typically provided by a user's hand or arm and is typically 0.1 to 10 N, preferably 0.2 to 5 N, and most preferably about 1 to 2 N.

The cleaning liquid can be sucked in by means of a suction tube that protrudes into the reservoir. The length of the suction tube is such that it reaches the bottom of the reservoir when the dispensing head and reservoir are connected.

The extraction device is characterized in that it comprises an angled holder. The angle is preferably 90° and can also be adjustable in order to adapt the extraction device to different installation positions. It is desirable that the orientation of the vertical axis of the removal device runs approximately vertically.

The holder has a first leg with a bore through which at least the suction tube can be passed. The diameter of the hole is, for example, 15 to 30 mm; but of course depends on the diameter of the section of the dispenser head to be guided through the bore.

The holder also has a second leg which is intended for attachment to a support surface such as a wall or mirror. It is clear that the distance between the center point of the bore and the second leg must be large enough that neither the reservoir nor the dispenser head should protrude beyond the outside of the second leg in an assembly position.

According to the invention, the first leg can be clamped between the dispenser head and the reservoir, so that the removal device can be fastened to an essentially vertical holding surface, for example, and can be actuated with one hand without the risk of slipping. The clamping is done with a force that is in any case so high that the connection is maintained when the dispenser head is actuated or the reservoir is hit from the side.

The invention thus avoids the disadvantages known from the prior art.

Due to the holder, the removal device according to the invention remains at a predetermined location even when it is mechanically actuated by means of a compressive force. A slipping or falling over of the removal device is thus easily avoidable; In addition, one-handed operation is ensured since the removal device no longer has to be held with the other hand. In addition, it can be attached to a wall, for example, to save space, which takes into account the often limited storage space in bathrooms.

Various embodiments of the invention are described in more detail below.

According to one embodiment, the surfaces of the dispenser head and reservoir that face each other are designed magnetically, so that a magnetic clamping force can be provided. To do this, the two surfaces can attract each other so that the leg in between is pinched, or the leg is magnetic so that it attracts the two components. A combination of both variants is also possible.

The advantage of this embodiment is that the two surfaces, which point in the direction of the leg, can be configured very simply and essentially flat.

According to another embodiment, the surfaces or areas of the dispenser head and reservoir designed to interact with one another are designed as a bayonet lock, so that a mechanical clamping force can be provided. Such an attachment is known from the prior art to be reliable and easy to attach and detach.

According to a further embodiment, the surfaces or areas of the dispenser head and reservoir designed for interaction are designed with threads, so that a mechanical clamping force can be provided. Threads are also a robust and easy-to-implement means of creating a mechanically reliable, detachable connection between two components.

According to a preferred embodiment, the reservoir has an end diameter at the end on the dispenser head side which is smaller than the diameter of the bore of the holder, so that this end can be passed through the bore.

In addition, on the side of the dispenser head, the reservoir has a shoulder which is spaced apart from this end and has a shoulder diameter which is larger than the diameter of the bore. Thus, only the end on the dispenser head side lying beyond the shoulder can be passed through the bore. The shoulder rests against the side of the second leg facing the reservoir.

The end of the reservoir on the dispenser head side has a bayonet catch or a thread.

Furthermore, the dispenser head also has a stop on the reservoir side, up to which the dispenser head can be guided through the bore hole from the side of the second leg opposite the reservoir. The suction tube has a smaller diameter so that it always fits through the hole and protrudes into the reservoir.

The dispensing head is adapted to cooperate with the dispensing head end of the reservoir while providing a clamping force. When the dispenser head and reservoir are screwed together, they both approach each other. In particular, the shoulder and the heel are approaching each other. Between these, the second leg of the holder is arranged, which is finally firmly clamped by the screwing forces.

The difference between the diameter of the bore of the second leg and the final diameter of the reservoir is preferably between 0.2 and 2.0 mm, so that the reservoir is centered in the bore. The difference can also be significantly larger if it is further ensured that the shoulder of the reservoir is at least partially in contact with the second leg; it is also possible that the hole is square or rectangular; however, a round bore is preferred.

According to one embodiment, the holder is made of stainless steel. It can be made from sheet metal, in which the hole is cut, drilled or punched, and which is then bent.

It can also be made of a suitable plastic or of wood or glass.

According to a further embodiment, the second leg has an adhesive layer on its side intended for attachment to a holding surface. This layer of adhesive is preferably covered by a film until the extraction device is to be fixed at the place of use. The adhesive layer can be in the form of double-sided adhesive tape or liquid adhesive.

According to another embodiment, the holder has one or more fastening holes on its side intended for attachment to a holding surface. The holder can then be connected to the holding surface permanently, but detachably if necessary, by means of appropriate screws.

According to a further embodiment, the second leg has one or more suction cups on its side intended for attachment to a holding surface. Using the suction cups, it can be attached to smooth surfaces in particular, as are often found in bathrooms and kitchens. The advantage of this embodiment lies in the particularly simple and residue-free type of attachment.

It is also conceivable that the reservoir has a suction cup on its side facing away from the holder, so that the removal device can be easily attached to a tiled ledge, which is adjoined by a tiled wall.

The cleaning liquid is preferably used for body care, ie it is intended for use in the bathroom or in the kitchen.

The reservoir can also preferably be changed without tools, for example due to the types of attachment to the dispenser head described above.

Finally, it is preferred that the dispenser head is used to generate foam from the cleaning liquid. For this purpose, the dispenser head has corresponding nozzles, which mix the outflowing cleaning liquid with air, so that a foam is produced during dispensing, which can be used, for example, to moisten wet wipes or hygiene tissues.

The advantage of dispensing foam on towels is that the liquid is distributed better and penetrates the mostly very absorbent towels less quickly, which would otherwise lead to them quickly softening.

The invention also relates to a holder of the type described above, adapted to cooperate with a reservoir and a dispensing head as described above.

character description

The invention is explained below by way of example using a figure.

In the only 1 is an exploded view of an embodiment of the extraction device according to the invention. This comprises a reservoir 10 designed as a bottle-like container, a dispenser head 20 with a suction tube 21, and a holder 30 that can be clamped between these two. The holder 30 has a bore 33 for this purpose. The reservoir 10 can be passed through this with its end 11 on the dispenser head side, with a shoulder 13 being present which prevents it from being passed through any further. The shoulder 12 has a shoulder diameter which is larger than the diameter of the bore 33 .

The end 11 of the reservoir 10 on the dispenser head side has a thread (not shown) on its surface 12 designed to interact with the dispenser head 20 .

The dispensing head 20 in turn has a surface 22 adapted to cooperate with the reservoir 10, here covered by the outside of the corresponding part of the pump housing. This also carries a thread (not shown). By screwing these two surfaces 12, 22, the reservoir 10 and the dispenser head 20 move towards one another until the shoulder 13 of the reservoir 10 and a stop 23 of the dispenser head 20 rest on the first leg 31 of the holder 30 on both sides, so that a mechanical clamping force is provided. which holds the holder 30 firmly in position.

The holder 30 can now be attached to a holding surface (not shown) with the outside of the second leg 32 by having fastening means (not shown) such as screws, adhesive or suction cups.
