Mouthpiece for a hose or the like.

Mouthpieces are attached to hoses, lines and the like used to splash, spray or just let liquids run out. Often you want to go through that If the liquid is dispensed from the mouthpiece, add another liquid, e.g. a detergent and / or preservative when cleaning, for example, automobiles, windows or the like. The same problem occurs also when watering plants with a hose, for example when using insecticides or fertilizers wants to mix in liquid form in certain plants.

Up to now the procedure has been such that the additional liquid substance is more or less separated into one Operation has been added or this substance has been added beforehand with the first FLüasigkeit, so for example Water mixed and then sprayed or splashed.

The invention has set itself the goal of a mouthpiece for spraying, atomizing or leaking liquids to create, with the help of which you can add another liquid to the dispensed liquid if necessary can. In particular, this mouthpiece should be economical to manufacture and easy to operate in use.

The invention thus relates to a mouthpiece for spraying, spraying or flowing liquids and is characterized by an attached or attachable container, which consists at least partially of flexible and not substantially expandable material, for receiving a second liquid to be added to the liquid, e.g. water, e.g. ₀ detergent, which is connected to the interior of the mouthpiece through a check valve.

For example, if you have the mouthpiece of a garden hose according to the invention with a soapy solution Container connects, then all that is needed is a pressure on the partially flexible wall part of the container, and the detergent is applied introduced into the water flowing through the mouthpiece and thus discharged with it.

In an expedient embodiment it is provided that the Container has a fill opening that can be closed by means of a stopper. Appropriately you can see on the mouthpiece a screw thread or the like, with which it can be attached to a hose. The check valve is expedient in one in the interior of the mouthpiece pointing protuberance is arranged on the side facing the outlet, spray or spray opening.

In a particularly awkward embodiment of the invention mouthpiece or container are formed in one piece with a common wall and the check valve is in this common wall arranged. It can be provided that the tubular mouthpiece with connection to a hose, a lateral flange is formed on which a hood made of deformable material for image xing of the container

Liquid, for example water, is to be entered. This fabric can, for example, be used for washing and preservation of surfaces of all kinds, e.g. windows, Walls, buildings, automobiles and the like, or it can also be a paint that is applied to the surface target. The mouthpiece that can be connected to a water hose or the like is a relatively rigid component and has a shaped like a deformable hood on container, which is located on the top of the mouthpiece and solid connected to her. Between the interior of the container and the interior of the mouthpiece is a passage or Opening with a self-closing valve through which material from the container is introduced into the water flow can by simply exerting such a strong pressure on the container made of resilient material that part of its contents is pushed through the valve. The outlet opening or nozzle of the mouthpiece has a slightly reduced size Cross-section so that the water escaping from the mouthpiece does not splash too much when it hits the wash Surface meets.

The mouthpiece 1o shown in Figures 1-4 has a Internal thread 1.1 for connection to a water hose 12. The middle part 13 of the mouthpiece connects the hose connection with the nozzle 14. The bore inside the mouthpiece is uniform with the exception of one protruding inward Protuberance 15> in which an opening 16 is provided, in turn for connection to a cavity Valve 18 is arranged with a self-closing slot 19.

The mouthpiece itself can be made of an inexpensive material, e.g. plastic, impregnated or coated

provided paper mache, rubber, fiberglass or the like. The mouthpiece has a saddle-like flange 2o with a flat surface 21, over which in a known manner, e.g. by welding or by means of adhesive 22, a container 23 made of such a material is attached which is light can be compressed or deformed without stretching, so that by pressing on the container fluid is pushed through the valve slot 19. To do this, for example, you can press the container with your thumb 24 and the fingers 25 can rest on the lower side of the mouthpiece opposite the thumb. This is how you press a part of the contents of the container into a water flow 26, which is represented by the arrows 27. If necessary, can a roughened or knurled section 28 on the mouthpiece to facilitate the grip, especially during the connection of the hose 12 may be provided.

The embodiment shown in Figures 5 and 6 is similar to that just described and also has an opening 29 in the container 23 with a reinforcing collar 3o around the opening. The opening can be a plug 31 record, which by means of a tape or strip 32 is attached to the container 23. The end of the stopper protruding into the container is relatively thin, soft and concave, so that it is enlarged when pressure is applied. «Because of the shape of the head of the stopper, the stopper seals when pressing with the thumb on the container from the opening 29 and it is through the check valve 18 and the Opening 16 injected liquid from the container into the mouthpiece. With the stopper or locking piece removed the container can be refilled and then used again.
