The same spray Direction is also designed so that they deliver spray and thus targeted  can produce local cooling. This mode of action can also increase Serve cleaning purposes, for example by adding an adhesive substance special chewing gum, cooled or iced, so that the substance of egg an item, such as a clothing textile or a tep pich, to which it adheres, can be removed in a tough or icy condition.

The local cooling that can be achieved by the spray device according to the invention However, it can also be used, for example, to generate icing, in particular for medical purposes. The local cooling effect can also used to correct thermal errors, especially in electrical appliances Find. The spray device is suitable for all of the aforementioned applications their design according to the invention can be used equally. The Ver application of the spray device according to the invention is nowhere near limited to a single special application.

The spray device according to the invention is actuated by its outlet nozzle is moved in the direction of the container. To the sprayer to Zwec ke to use the drain cleaning, that of the outlet nozzle Cap attached to the opening of the drain, and the container of the spray before direction is operated in the direction of the cap or the drain. Because of the Pressure of the spraying agent flowing from the container into the drain contaminants and blockages in the drain are loosened. The usage for the purpose of local cooling is done by actuating the spray device while she is upside down. If namely after the outlet nozzle points below, the liquid part of the spray can escape from the container and evaporate.

If the cap and the gas mixture are such that the spray before direction can also be used for blow-out cleaning, this is the Spray device according to the invention in an advantageous manner for an even larger Number of different types of cleaning applicable. It makes it possible in this Additional case, electronic, electrical or mechanical devices, in particular  re office machines, keyboards, circuit boards and watch cases, from dirt or dust by blowing out with the gas mixture. The out kick nozzle of the spraying device must point upwards so that the lighter, gaseous part of the spray flows out of the container. The invent spray device according to the invention advantageously leaves none liquid, solid or film-like residues.

It is preferred if the cap of the spray device according to the invention is designed such that its side having the outflow opening on one Opening a drain is attachable, so that the escape from the out flow opening spray in other directions than that of the drain is disabled. This can cause contact between the cap and the drain take place along an annular surface which is the outflow opening or the opening of the drain surrounds. This will inadvertently escape the Spray from the spray device on the side of the opening of the drain prevented by.

The drain may be a sink or is a flushing water drain from a urinal or flushing toilet. In the latter case, it is advantageous to use the cap as a triangular cap or as Round cap form so that the opening of the drain along a three corner-shaped or an essentially round ring surface opposite to the side Flowing past the spray is sealed and the spray in the we flows in the direction of the drain.

The cap can be made as a molded part. Furthermore, it can be used as a hollow cylinder be formed, the one end facing the container of the Hollow cylinder is open so that the cap partially surrounds the container. The other end face can be convexly curved outwards and towards the center of the container. The outflow opening of the cap is located in this case, in the middle of the recessed area, and from this  protrudes in the direction of the container a pipe neck, which is the outlet nozzle of the container or engages with the outlet nozzle.

The outflow of the spray medium from the container of the spray device can be actuated in the direction of the container by actuating the outlet nozzle or the cap nisses be caused. If the cap is attached to a drain opening, the spray device can be actuated in that the container in Direction of the cap attached to the drain opening is moved.

The cap can ver with the container or the outlet nozzle of the container be clickable, and it can be removable. It is preferred if the Spray device with the cap removed in the area of the outlet nozzle can be provided with a spray head. This spray head has an off through the outlet nozzle of the container into the spray Spray flowing through the head can escape. It is also preferred if the spray head causes a deflection of the spray.

This spray head can be used for the targeted delivery of the spray agent during production local cooling or blow-out cleaning. To this Purpose, it can be particularly advantageous if an elongated, hollow cylindrical Tube attachment can be plugged onto the outlet opening of the spray head. It is preferred if the cap has a snap holder in which the Tube attachment of the spray head and / or the spray head itself can be attached.

The spray head is preferably with the container or the outlet nozzle of the loading ratio lockable. The outflow of spray from the container through the outlet nozzle and the spray head by pressing the spray head in the direction of the container, especially with a finger will.

Alternatively to attaching a spray head to the container of the spray Direction can also be the outflow opening of the cap tubular or tubular  be shaped or with a spray hose or a hollow cylinder be sprayed. This configuration can also targeted delivery of the gaseous or liquid spray is made possible, especially when using the spray device for local cooling or for blow-out cleaning. In this case, it is not necessary Cap removable from the container and a spray head or egg to attach a spray head with a tube attachment to the container.

The spray or spray attached directly to the outflow opening of the cap hose or spray tube can in particular deflect the spray cause. The spray hose or the spray tube can also in the Snap holder of the cap can be attached.

It is advantageous if the cap or the triangular cap or the round cap so flexible in the area of the end face which has the outflow opening is that the shape of this end face when attached to an opening of a Drain adapts to the shape of this opening. Thus the escape of Spray that flows out of the outflow opening of the cap, through the side Gap between cap and side edge of the drain additionally obstructed and the pressure with which cleaning is carried out increases.

Further preferred embodiments of the invention are in the subclaims Chen described.

The invention is described below using exemplary embodiments under Be described with reference to the drawings; in these show:

Fig. 1 is an enlarged side view of a container according to a spraying device Invention,

Fig. 2A and 2B, a broken-half side view and a plan view of a cap of a spray device according to the invention, and

FIGS. 3A and 3B is an enlarged, partially broken away side view and broken in half plan view of a spray head with attached stecktem tube attachment.

Fig. 1 shows an enlarged side view of a container 1 of a spraying device according to the invention. The container 1 is designed as a cylindrical metal can. The container 1 tapers towards the upper end face, and there it is provided with a metal cover 2 which has an outer round brim encompassing the container 1 and an inner round brim encompassing a central opening. Between the two brims, the metal cover 2 has an annular recess 3, not shown in FIG. 1, which is offset in the direction of the container 1 .

Within the central opening of the metal lid 2 is a hollow cylindrical outlet nozzle 4 , which partially protrudes into the container 1 and partially protrudes from it. The outlet nozzle 4 , the metal lid 2 and the container 1 are arranged on a common longitudinal axis.

The upper end of the wall protruding from the container 1 of the outlet nozzle 4 is gradually enlarged radially outward to an annular flange 4 a, which tapers conically to the upper opening of the outlet nozzle.

Inside the container 1 there is a partially liquefied gas mixture as a spray at a pressure of about 8 bar. By actuating the outlet nozzle 4 in the direction of the container 1 , spray means flows from the container 1 through the outlet nozzle 4 due to a known valve mechanism (not shown in FIG. 1 ) . If the outlet nozzle 4 , as shown in FIG. 1, points upward, lighter, gaseous spraying agent flows out of the container 1 . If, on the other hand, the outlet nozzle 4 points downwards, heavier liquid spray can flow out of the container 1 and evaporate.

FIG. 2A shows a side view of a cap 5 of a spray device according to the invention, which has been broken open in half. The hatched parts have a zen around the longitudinal axis of the cap 5 rotationally symmetrical on construction. In Fig. 2B, the cap is shown in plan view. 5

The cap 5 has a hollow cylindrical base body 6 . The hollow cylinder 6 is open on its lower end face, and on the upper end face 7 it is curved in a convex manner in the direction of the longitudinal axis of the cap 5 . In a central region 8 , which occupies approximately one third of the diameter of the hollow cylinder 6 , the upper end face 7 is set back in the direction of the lower end face. The set-back area 8 also has a structure which is rotationally symmetrical about the longitudinal axis of the cap 5 . In the middle, the area 8 to be set back has an outflow opening 9 , the diameter of which corresponds to the inside diameter of the hollow cylindrical outlet nozzle 4 of the container 1 shown in FIG. 1.

Furthermore, a hollow cylindrical tube extension 10 projects a short distance from the recessed area 8 in the direction of the lower end face of the cap 5 . The outer diameter of the tube extension 10 is approximately half the diameter of the recessed area 8 , and its inner diameter corresponds essentially to the outer diameter of the wall of the outlet nozzle 4th Thus, the outflow opening 9 forms an inwardly directed annular shoulder 9 a with respect to the tubular extension 10 .

On the lower, open end face of the tube extension 10 , the wall thereof is flattened inclined upwards toward the inside. Between the outflow opening 9 and the lower end face, the tube extension 10 has on its inside a perpendicular to the longitudinal axis of the cap 5 , annular pre jump 10 a for engaging the ring flange 4 a of the outlet nozzle 4 .

In addition, a tubular sealing cylinder 11 is formed on the recessed area 8 , the diameter of which corresponds to that of the recessed area 8 . The sealing cylinder 11 protrudes in the direction of the lower end face beyond the tube extension 10 and is open at the bottom.

The cap 5 also has six evenly spaced, radially directed in the direction of the longitudinal axis of the cap 5 longitudinal ribs 12 in its interior. The longitudinal ribs 12 extend from the beginning of the recessed area 8 on the upper end face 7 along the hollow cylinder 6 on the inside thereof to the lower end face of the cap 5 .

Finally, the cap 5 has a snap holder 13 arranged on the outside of the hollow cylinder 6 , in height and parallel to the lower end face of the cap 5 . This consists of two tongues which are arranged side by side in such a way that the space essentially forms a round opening.

The in Figs. 2A and 2B as shown cap 5 is attached to the ge in Fig. 1 showed container 1 mounted. For this purpose, the lower, open end face of the cap 5 is placed on the upper end of the container 1 until the tubular extension 10 engages around the outlet nozzle 4 and the outlet nozzle 4 abuts the annular shoulder 9 a formed by the flow opening 9 of the recessed area 8 .

The insertion of the outlet nozzle 4 into the pipe socket 10 is facilitated by the inclined configuration of the wall of the pipe socket 10 . In addition, the longitudinal ribs 12 of the cap 5 lie essentially against the outer surface of the container 1 , and thus center the cap 5 with the tubular extension 10 and the sealing cylinder 11 and the container 1 on a common longitudinal axis.

Due to the upper end of the outlet nozzle 4 formed Ringflan ULTRASONIC 4 a and corresponding to the inside of the tubular extension 10 of the ring formed projection 10 a patch on the container 1 cap 5 can latch detachably with the container. 1

The convex curvature of the upper end face 7 of the cap 5 enables the use of the illustrated spray device according to the invention for drainage. For this purpose, the spray device is turned upside down, and the end face 7 is placed centrally at a round drain opening. If the loading ratio 1 is now moved in the direction of the discharge opening, this corresponds to an actuation of the outlet nozzle 4 seated on the ring shoulder 9 a of the discharge opening 9 relative to the container 1 . As a result, spray flows straight from the container 1 through the outlet nozzle 4 of the container 1 and the Ausströmöff opening 9 of the cap 5 in the opening of the drain. The spraying agent thus flowing in the direction of or along the outflow is able to detach and carry away impurities in the flow, so that the outflow is cleaned due to the pressure effect of the spraying agent.

To carry out such a drain cleaning, it makes sense to fill the area above the drain opening with water to a height of approximately 5 cm, so that the annular gap between the drain and the end face 7 of the cap 5 surrounds the water along the circumference of the cap 5 is. As a result, when the spray device attached to the drain opening is actuated, an undesired lateral flow of the spray medium through the annular gap is impeded.

The area 8 set back within the end face 7 increases the possible cross-section of the flow of the spray medium from the outlet nozzle 4 into the drain. If the opening of the drain is partially covered, for example, by a protective grille, in particular in the central region of the opening, a straight-line flow of the spray medium from the cap 5 into the drain can be impeded due to this covering. In this case, however, the spray medium can also flow laterally past the cover into the drain due to the increased flow clearance in the recessed area 8 .

The end face 7 is convexly curved around the set-back area 8 in such a way that it can seal drains of different diameters to which it is attached: The lateral flow of spray medium through a gap between the end face 7 and the opening of a drain is essentially essential prevented.

The sealing cylinder 11 arranged on the recessed area 8 of the cap 5 prevents spray medium from flowing out of the outlet nozzle 4 through the pipe extension 10 and the open end face of the cap 5 facing the container 1 . For this purpose, the sealing cylinder 11 engages in the recess 3 between the inner and the outer brim of the metal cover 2 of the container 1 .

The actuation of the spray device attached to a drain opening is stabilized in the longitudinal direction in that the longitudinal ribs 12 of the cap 5 bear laterally on the lateral surface of the container 1 and the cap 5 lead in the longitudinal direction.

Fig. 3A shows an enlarged, partially broken away side view of a spray head 14 of a spray device according to the invention. FIG. 3B shows the same spray head 14 in a plan view, which is broken up in half parallel to its plane, namely at the level of the line SS drawn in FIG. 3A.

The spray head 14 has a hollow cylindrical base body 15 . The lower end face of this hollow cylinder 15 is open and provided with a brim 16 which is offset to the outside and is open at the bottom. The hollow cylinder 15 is closed on its upper end face and there has an actuating trough 15 a.

From the upper end of the hollow cylinder 15 protrudes in the direction of the center of the spray head 14, a substantially hollow cylindrical tube extension 17 , the diameter of which is approximately half the diameter of the hollow cylinder 15th The tube extension 17 and the hollow cylinder 15 lie on a common longitudinal axis.

The lower end face of the tube extension 17 is open, and its wall is flattened there inclined upwards towards the center. The tube extension 17 has on its inner surface, approximately halfway up, an annular projection 17 a running perpendicular to its longitudinal axis, into which the annular flange 4 a of the outlet nozzle 4 can snap.

The upper end face of the tubular extension 17 essentially joins the upper end face of the hollow cylinder 15 . Near the latter end, the tube extension 17 opens in the direction of the axis SS to an outlet tube 18 . The longitudinal axis SS of the outlet pipe 18 is perpendicular to the longitudinal axis of the pipe extension 17 . The outlet pipe 18 essentially has a hollow cylindrical structure. It crosses the wall of the hollow cylinder 15 and protrudes away from the spray head 14 . The face of the spray head 14 facing away from the outlet tube 18 is designed as an outlet opening 19 .

The inner regions of the outlet pipe 18 and the pipe extension 17 are thus connected by a cylindrical channel which has a 90 ° change in direction in a 20 Umlenkungsbe. The inner diameters of both the tube extension 17 and the outlet tube 18 taper at a step-shaped ring shoulder 20 a or 20 b near the deflection region 20 . These two ring shoulders 20 a, 20 b thus delimit the inner region of the tube extension 17 or the outlet opening 19 of the outlet tube 18 from the deflection region 20 .

Within the outlet opening 19 of the outlet tube 18 is a längli cher, hollow cylindrical tube attachment 21 , which projects to a large extent from the outlet tube 18 . The outer diameter of the tube cap 21 is dimensioned such that the tube cap 21 can be inserted into the outlet opening 19 with a close tolerance so that it abuts the ring shoulder 20 b of the steering region 20 . The inside diameter of the tubular attachment 21 corresponds essentially to the diameter of the cylinder duct of the deflection region 20 facing the outlet pipe 18 . Both end faces of the tube attachment 21 are open.

It is possible to attach the tube attachment 21 together with the attached spray head 14 for storage in the snap holder 13 of the cap 5 shown in FIGS . 2A and 2B.

The spray head 14 shown in FIGS . 3A and 3B can be plugged onto the outlet nozzle 4 of the container 1 shown in FIG. 1. From the exit nozzle 4 is inserted into the pipe socket 17 until the upper end of the outlet nozzle 4 sits on the ring shoulder 20 a, which separates the pipe socket 17 from the deflection region 20 of the spray head 14 . The ring flange 4 a of the outlet nozzle 4 crosses the annular projection 17 a within the tube extension 17 and locked with this. The insertion of the outlet nozzle 4 into the pipe socket 17 is facilitated by the inclined flattening of the ring flange 4 a of the outlet nozzle 4 or the wall of the pipe socket 17 .

If the container 1 is provided with the spray head 14 , the spray device according to the invention can be actuated by moving the spray head 14 in the direction of the container 1 . In this case, the outlet nozzle 4 , which is seated on the ring shoulder 20 a, is actuated in the direction of the container 1 . Through this actuation of the outlet nozzle 4 , spray medium flows from the container 1 through the outlet nozzle 4 into the deflection area 20 of the spray head 14 , is deflected in the deflection area 20 in the direction of the outlet pipe 18 , and flows out of the outlet opening 19 of the spray head 14 or from the tube top 21 . The movement of the spray head 14 in the direction of the container 1 is facilitated by the operating recess 15 a. Through this, if the container 1 is gripped with one hand, the spray head 14 can be easily operated with a single finger.

When the spray head 14 is actuated in the direction of the container 1 , the brim 16 formed on the lower end face of the hollow cylinder 15 engages in the ring-shaped recess 3 in the metal cover 2 of the container 1 . As a result, the outflow of spray medium flowing out of the outlet nozzle 4 through the tube extension 17 and the hollow cylinder 15 back in the direction of the container ses 1 is hindered.

If the spray device is to be used for the purpose of blow-out cleaning, it is useful if the tube attachment 21 is inserted into the outlet opening 19 . If, when the container 1 is in the upright position, the spray head 14 is actuated in the direction of the container 1 , gaseous spray medium flows from the container 1 through the outlet nozzle 4 , the deflection region 20 of the spray head 14 and the tube attachment 21 . Can be particularly given well targeted during the spray using the tube seating 21, the Ausblasreinigen is also using the spray head 14 without plugged tubes 21 tower possible.

If, on the other hand, the spray device according to the invention is to be used for the purpose of cooling or icing, the container 1 must be turned upside down so that the liquefied part of the gas mixture contained can escape. If the spray head 14 is actuated in this position in the direction of the container 1 , liquefied spraying agent flows through the outlet nozzle 4 , the deflection region 20 and the outlet pipe 18 from the outlet opening 19 of the spray head 14 . The spray evaporates and is thus in a cooled, gaseous state. This mode of operation of the spraying device according to the invention can be exploited, for example, to freeze substances adhering to clothing or mobile textiles, such as chewing gum, in order to be able to remove them easily in the iced-up state. In this type of use of the spray device according to the invention, the tube attachment 21 can be plugged into the spray head 14 ; however, it is preferred if the spray head 14 is actuated without the tube attachment 21 attached.

Thus, the spray device according to the invention shown in FIGS . 1, 2A, 2B, 3A and 3B is to be used at least for three different cleaning purposes, namely for drain cleaning, blow-out cleaning and for removing adhesive substances. For this purpose, the cap 5 may only have to be interchanged with the spray head 14 . The tube attachment 21 can be used in the use for blow-out cleaning or for the local generation of cold, the more targeted delivery of the spray.
