• Fig. 3 a rear view of the nasal douche behind Fig. 1 and 2 shows; and
• Fig. 4 a perspective view of the nasal douche Fig. 1 to 3 from the side behind shows.

To explain a first exemplary embodiment is below Fig. 1 to 4 Referenced.

In the example shown, the nasal douche designated as a whole by 1 consists of only two components, namely a container 2 and a cover 4 screwed onto it and screwed onto it.

The container is made of an elastic material with high restoring force such as polyethylene, polypropylene or similar. made and may be transparent, transparent or opaque inked, especially multicolored to highlight individual games, with a multicolored training, especially when used as a child's shower. The elasticity of the container body is sufficient for it to be compressed for the purpose of dispensing a liquid received therein. Mold and material should allow for automatic recovery from the compressed state.

The container 2 is designed for the purpose of receiving rinsing liquid (for example water with dissolved active ingredients such as salts or the like) and compact for practical handling, for example in (flattened) spherical, ellipsoidal, cylindrical, cubic or conical shape, or is composed of several such simple basic geometric shapes. Gripping aids or grip depressions may be formed on the container body 2, such as offset edges 10, which may also serve for the optical design of the container body, as in the example shown, which is reminiscent of an elephant in a simplified, child-like form.

The container 2 has according to its outer shape and its wall thickness on an internal volume or receiving volume, which is flattened spherical in this example and has a center of gravity 6. In other words, when the container is completely filled with a homogeneous liquid, the liquid body contained therein has the center of gravity 6.

The container 2 has on its underside a flattened standing area 12, which defines a standing plane 14. Instead of such a flattening of the container forming basic shape could alternatively feet or similar approaches may be provided with which a shutdown of the nasal douche on a flat surface is possible. As a further alternative, an interpretation of the nasal douche into consideration, in which the center of gravity in the empty and / or in the filled state is arranged so that the nasal shower stops alone due to the center of gravity in the desired position, ie approximately in the Fig. 1 shown position in which the level plane 14 corresponds to the horizontal. Finally, a holder could be provided for the container 2, which could then be formed without any support stands.

The container 2 has in an upper, the stand area 12 opposite region on a cylindrical projection 13 which forms a filling opening 16, wherein the approach is externally threaded, so that the lid 4 can be screwed. The lid 4 is provided with a ventilation opening 18.

An outlet pipe or outlet channel 8 starts from a floor area 20 adjacent to the floor area 12 and is directed with its longitudinal axis 8a at an angle β of approximately 45 ° upwards to the floor level 14.

The outlet channel 8 has, in its part adjacent to the base region 20, a relatively large cross-section which steadily decreases in the direction of a free end 22 of the outlet channel 8. This shape is used in the illustrated example essentially design purposes. Alternatively, the outlet channel 8 could have a constant or otherwise variable over its length cross-section.

At the free end 22 of the outlet channel 8, a thickened end portion 24 is arranged, in this example in the form of a ball, in which a scavenging port 26 is formed, which communicates with the outlet channel 8 and the interior of the container 2. The flushing opening 26 is higher than the filling opening 6, based on the standing plane 14 as a horizontal.

The flushing opening 26 is directed in an outlet direction 28 which is determined by the local longitudinal direction of the outlet channel at the location of the flushing opening or in that a liquid jet emerging under pressure from the flushing opening 26 moves (initially) along the outlet direction 28.

The exit direction 28 is arranged in this example with respect to the container 2 so that it with an (imaginary) direction line 30, starting from the scavenging port 26 and directed to the center of gravity 6 of the container 2, an angle α of not more than 120 ° includes. At the in Fig. 1 illustrated embodiment, the angle α is about 55 °.

The outlet direction 28 forms with the central longitudinal direction 8a of the outlet channel 8 (or also with its local longitudinal direction at the location of the flushing opening) an angle δ of between 20 ° and 120 °, here about 65 °,

For use, the nasal douche 1 is completely or partially filled with a desired rinsing liquid, the lid 4 expediently unscrewed, filled the rinsing liquid and the lid 4 is screwed back, then the nasal douche 1 is grasped with one hand and, for example, with the index finger the vent opening 18th locked. Then the nasal douche 1 opposite to in Fig. 1 shown horizontal position about an axis perpendicular to the plane of representation axis rotated by an angle of, for example, almost 90 ° clockwise, so that the outlet direction 28 is substantially vertical. In this position, the thickened end portion 24 is brought into sealing engagement with a nostril so that the flushing orifice 26 faces inside a nostril. This is possible due to the inventive design of the nasal douche in an upright, relaxed head posture.

A flushing of the nose can take place in that the ventilation opening 18 is released and the rinsing fluid flows upright head keeping and closed soft palate one nasal passage high, the nasal septum flows around and flows down to the other side without the head must be tilted.

The container body 2 can be completely emptied without pressure. If desired, for example in the event of obstacles in the nose, it is alternatively possible, with the ventilation opening 18 closed, to compress the container body and to increase the pressure. Due to the individually adjustable pressure, the nasal cavity can also be rinsed in its upper areas, where otherwise no rinsing liquid would pass.

To explain a second embodiment is again on Fig. 1 to 4 Referenced.

The second embodiment is identical except for the differences explained below with the first embodiment, so that reference is made in this regard to the preceding description in this respect.

Fig. 1 shows a plane perpendicular to the plane of reference plane 34, which passes through both the filling opening 16 and the scavenging port 26, wherein the reference plane 34 extends in this example through a point or region of the filling opening 16, which is the level plane 14 initially, ie in the illustrated orientation the nose shower is the lowest. The reference plane may alternatively run through any area of the filling opening and the flushing opening, which may result in certain changes in position of the reference plane with respect to the position shown here.

Characteristic of the second embodiment is first that the filling opening 16 is arranged so that on one side, i. here on the underside of the reference plane 34 (the illustration shows an orientation in which the earth gravity direction 36 points vertically downwards), a filling proportion of almost 100% of the receiving volume of the container. Only a small part of the inner region of the cylindrical threaded projection on which the cover 4 is screwed, is located above the reference plane 34. With horizontal position of the reference plane (and corresponding position of the nasal douche), the container can thus be filled to nearly 100 °.

Another essential feature of the second embodiment is that the outlet direction 28 of the outlet channel, which has this in the flushing opening 26, with the reference plane 34, viewed in the direction of the filling opening 16, forms an exit angle φ of less than 150 °, in this example about 30 °. The range φ = 150 ° ... 0 ° is indicated by dashed lines.

According to the invention, the exit angle φ is less than 60 °.

The advantage of such an arrangement is first that the nasal douche in an orientation as in Fig. 1 is shown, or even in an orientation in which the reference plane 34 is arranged horizontally, can be completely or practically completely filled without liquid already exiting the flushing opening, and without a valve o.ä. is required.

After filling, the nasal douche without actuating a valve or similar. only by tilting at an angle of about 35 to 100 ° about an axis perpendicular to the plane of representation are used, since in such a position in which the reference plane 34 assumes an angle of, for example, 45 ° with the horizontal and the flushing opening a forms almost deepest point of the nasal douche, the flushing liquid contained in the container exits due to gravity from the flushing opening 26 in an upward direction. The outlet direction 28 may in this case be directed vertically upwards or is within a range of, for example, ± 30 ° or ± 60 ° (maximum ± 90 °) to the vertical direction.

The nasal douche according to the invention can thus also be described in such a way that when vertical alignment of the filling opening, or in an orientation in which it forms the uppermost point or area of the container, the container can be filled to at least 75% without rinsing liquid can escape from the flushing opening (flushing opening at the level of the filling opening), and that when the container is rotated about an axis perpendicular to the plane of representation by 35 ° to 100 ° clockwise, the flushing liquid flows through the flushing opening in an outlet direction, which is directed upward, ie within a range of ± 90 ° to the vertical direction upwards.

This orientation of the outlet direction has the advantage that the nasal douche can be used in upright, relaxed head posture.
