Definitions
- the invention relates to a gravity feed cup for a paint spray gun according to the preamble of claim 1.
- the flow cups of this type known from the prior art have a mechanical ventilation device with which the flow cup can be ventilated during the paint spraying process. Ventilation of the flow cup is necessary so that the spray medium emerging from the paint cup due to the force of gravity and the negative pressure created at the nozzle set can flow unhindered out of the paint cup so that it can flow into this joint without creating a vacuum in the paint cup.
- the volume of the liquid that has already been sprayed must be replaced by air flowing into the flow cup via the ventilation device. It is known for this purpose to make ventilation openings in the gravity-feed cup, which are preferably closable via a valve.
- Such a gravity feed cup is known, for example, from WO98 / 32539-A.
- This gravity-feed cup is intended for single use and comprises a plastic container and a lid that can be placed thereon to close the container. Connection means are provided on the cover for placing and securing the flow cup on a paint spray gun or an adapter attached to it.
- the gravity-feed cup is placed "upside-down" on the paint spray gun, with the top of the lid facing down.
- the liquid in the gravity cup, in particular paint then flows downwards into the paint inlet channel of the paint spray gun due to negative pressure and gravity.
- a ventilation opening is made in the container base, which enables pressure equalization between the interior of the flow cup and the environment.
- the ventilation opening can be closed by means of an adhesive strip or a manually operated valve.
- the mechanical ventilation devices known from the prior art have the disadvantage that, through the ventilation opening in the gravity feed, not only air flows into the gravity feed can flow in, but in certain situations during the paint spraying process, for example when painting overhead or with rapid pivoting movements of the paint spray gun, liquid can escape from the ventilation opening. This is uncomfortable for the painter and can lead to contamination. If paint inadvertently splashes through the ventilation opening onto the surface to be painted, this may require renewed surface treatment.
- the invention has the object to provide a gravity cup for a paint spray gun, in which a sufficient, z. B. automatic, pressure equalization between the inside of the gravity flow cup and the environment is guaranteed and at the same time the leakage of liquid during the paint spraying process and during storage can be avoided.

- Ventilation opening with a membrane made up of several segments is a membrane made up of several segments.
- the first embodiment of a flow cup according to the invention shown in FIG. 1 comprises a cup-shaped container 1 and a cover 2 that can be screwed onto it via a thread.
- the cover 2 has an outlet connection with an outlet opening on its underside (as shown in the top view in FIG. 1).
- a connection part 3 is formed on the outside of the outlet nozzle and is used to place and fasten the gravity cup on a paint spray gun or on an adapter arranged between the paint spray gun and the flow cup.
- the connection part 3 comprises a thread and a wedge-shaped groove which interact with corresponding connection elements on the paint spray gun or an adapter, namely a corresponding internal thread and a pin for engaging the groove.
- Both the container 1 and the lid 2 are expediently manufactured from plastic by injection molding.
- the container 1 has walls, namely a bottom la and a frustoconical side wall lb.
- On the bottom la is a (in the upper representation of FIG. 1) protruding upwards over the bottom la and encircling the outer circumference of the container 1 educated.
- the cover 2 is first removed and the container 1 is placed with the bottom la down on a base and finally filled with a liquid, in particular paint. After filling, the cover 2 is put back on.
- the flow cup is turned over and the connection part 3 is placed and fastened to the corresponding connection part of the paint spray gun or an adapter which may be arranged thereon.
- the gravity flow cup is on the top of the paint spray gun and the liquid in the container runs into the paint inlet channel of the paint spray gun due to gravity and the suction effect of the nozzle.
- a ventilation device is provided on the gravity flow cup.
- This ventilation device is of a z. B. circular ventilation opening 6 formed in the bottom la, in which an air-permeable and at the same time liquid-tight membrane 4 is inserted. The membrane 4 thus closes the ventilation opening 6 in a liquid-tight manner, but because of its air permeability it ensures adequate ventilation of the flow cup during the painting process.
- the air-permeable and liquid-tight membrane 4 is a porous membrane.
- porous materials allow gaseous substances, in particular air, to pass through the material (e.g. diffuse and / or by "normal" flow of a gas through the pores of the membrane), but are also suitable for liquids, in particular for paints , impermeable.
- these materials are not wetted even by liquids with very low surface tension and remain “breathable”, so they still allow air to pass through (e.g. diffuse or flow through) when they come into contact with liquid .
- the membrane 4 is in a support and / or a protective structure in the form of a frame 5.
- the frame 5 is formed by a circular disc 5a which is connected to an inner cross 5b arranged centrally to the circular disc.

- the frame 5 is positively inserted in the bottom la in the ventilation opening 6.
- the frame 5 is preferably fastened in a clamping manner in the ventilation opening by means of a clamping connection. This ensures that the frame 5, which holds the membrane 4 attached thereto, can be exchanged for changing the membrane 4. It may be necessary to change the membrane 4 after a long period of use or if dried paint has closed the pores of the membrane 4.
- FIG. 2 The embodiment of a flow cup for a paint spray gun shown in the drawing in FIG. 2 is a flow cup with container 1 and a cover 2 that can be removed via a threaded connection, the connection part 3 for placing and fastening the flow cup on the paint spray gun not as in the case of The embodiment shown in FIG. 1 is arranged on the cover 2 but here on the underside of the container 1.

- the ventilation opening 6 and the membrane 4 which closes it air-permeable and liquid-tight are arranged in the cover 2.
- the membrane 4 can be clamped in a frame 5 which is inserted into the ventilation opening in a form-fitting manner and in particular in a clamping manner.
- the membrane 4 can be poured into the cover 2 directly during the manufacture of the cover 2 in the injection molding process so that it covers the ventilation opening 6, as can be seen from the upper illustration of FIG. 2 in the area shown in the elevation.
- the membrane 4 is inserted into the injection mold during the injection molding process and the edge 7 (FIG. 2, top) is encapsulated by the plastic during the injection molding process.
- the membrane 4 then covers the opening 6 in the cover 2 and thereby ensures that the cover 2 is on the one hand permeable to air in order to ensure the necessary pressure equalization during the application process, but on the other hand prevents that liquid can splash out of the flow cup through the ventilation opening 6.
- FIGS. 3 to 8 show further exemplary embodiments of a ventilation opening 6 with one or more membranes 4.

- the membrane 4 is embedded in the surrounding material la of the flow cup.
- a firm anchoring of the membrane 4 is ensured by the fact that the membrane 4 has a thinner anchoring ring 9 around its outer circumference, which is formed during the primary molding (e.g. during injection molding) of the cup base (or cup lid etc.) or at least the part of the cup base surrounding the membrane 4 is poured or embedded in the material.
- the membrane 4 of the embodiment shown in Figure 3 is shown in a plan view.
- the anchoring ring 9, which is reduced in height, can be formed by pressing, compressing, welding, removing, etc.
- the membrane 4 can also be produced with the thinner anchoring ring 9.
- the anchoring ring 9 is preferably made of the same material as the rest of the membrane 4. Alternatively, it can also be made of a different material and, with the rest of the membrane 4, material and / or be positively connected (glued, welded, clamped, etc.).
