said device is arranged to direct said valve chamber to refill a corresponding amount of said product from said inlet portion of said passageway, and said device to connect said inlet conduit of said device to an interior of said container. It has a connecting piece attached to one part of the container glue.

BACKGROUND OF THE INVENTION Several different dispensing devices of the aforementioned type have been known for some time. Without exception, these known devices
Used individually for dispensing liquid or pasty products from a placed container. The generally cylindrical channel in the valve housing is always formed as a through passage, and the connecting piece is always placed in alignment with the passage at the artificial end of the passage by means of a connecting piece in which the device is attached to the head of the container. In practice, when using these published devices, it may be necessary to have a special support device after the valve housing to absorb the relatively high forces exerted on the valve housing in connection with the operation of the pressure device. I can't come.

-1 Problems to be Solved by the Invention The present invention provides for that purpose a new and improved device of the type originally detailed which eliminates the requirement for a separate support device for the valve housing. Must be. To this end, according to the invention, said connecting piece is attached to a second external circumferential part of the valve housing, which is arranged diametrically opposite the first-mentioned external circumferential part of the valve housing, and said connecting piece is attached to said inlet. a circumferential wall of said inlet portion, wherein a conduit extends through said second external circumferential portion in a direction substantially transverse to the pre-Me communication passageway and is closed by an end wall of the valve housing at an end of the outlet portion remote from the valve chamber; There is provided a dispensing device of the above type characterized in the first place in that it terminates in an inlet opening.

28 Means for Solving the Problems The present invention provides that when a device is mounted on the head of a container, the valve housing is electrically distributed across the head relative to said head, and the pressure device is connected to the opposite side of the housing. , will be positioned in alignment with the head portion. Thereby, the forces exerted on the valve housing in connection with actuation of the pressure device are completely absorbed by the container. Therefore, any separate support device will no longer be required. having a head portion at the upper end of which a dispensing device is mounted in order to make it possible to also use a dispensing device for dispensing a liquid or paste-like product from an upright container, the external part of the artificial conduit being in said container; It is formed by a tube piece projecting outwardly from said second external circumferential portion of the valve housing to form a connection for an inserted hose.

In order to enable the dispensing of the liquid or pasty product in a convenient direction, the outlet conduit is formed by an elongated outlet tube, regardless of whether the device is installed in the upper or lower head part of the container, and the said passageway an inner end portion rotatably mounted within the valve housing at an end of the housing disposed proximate an outlet portion of the valve housing, and an outer end portion with an outlet conduit terminating in a radial discharge opening.

The invention will now be described in more detail, with reference to one of the accompanying drawings as an example.

The housing 11 is manufactured as an integral part by injection molding from a hard deranutic material such as seripropylene.
It has a main body that forms a. Said valve housing 11 has a main body with a generally horizontal hollow cylindrical shape having an open end portion 13 closed at one end thereof by an integral end wall 12, while at the other end an elongated outlet tube 14 is attached by a cylindrical end portion 15. have a part. - On its upper side, the valve housing 11 has an external circumferential part with an approximately circular plate 16 with two annular flanges 1γ and 18 projecting from the outside of the circular plate. Board 16
generally acts on the support of the compression pressure device formed by the hemispherical pressure method 19. For example, the pressure method 19 made of ethylene ginyl acetate may be used at the flange 17.
It has an annular, leg flange 20 held in tight seal contact with plate 16Vc by a retaining ring 21 cooperating with plate 16Vc.

Opposite the plate 16 on its lower side, the valve housing 11 has a second external circumference 22 of approximately cylindrical shape. This second external circumferential portion 22 has a neck portion 24 which is threaded onto the exterior of the container 25 in which the device 10 contains a liquid or pasty product.
It serves to support the threaded cup-shaped connecting portion 23 attached to the Vc.

Connecting portion 23 is freely rotatably mounted on portion 22 by an internal annular edge portion 261c received in an annular external groove 27 within portion 22.

Within the cylindrical main part of the valve-housing 11 a generally cylindrical passage 28 is formed through which the liquid or paste-like product contained in the container 25 is fed to the outlet pipe 14. Two valve arrangements mounted at separate and spaced locations within the passageway 28 allow the passageway to be connected to the artificial section 28a1 and the exit section 28b.
and an intermediate valve chamber 28C.

The valve device has a 30th disc-shaped Jf portion having a swing portion 31 which is mounted in an axially fixed position in the passageway 28 on a support pin 32 arranged centrally in the passageway. It is formed by a circumferentially elastically flexible, generally funnel-shaped flange 29. The support bottle 32 is integrally formed with a valve nose protruding from the port wall 12. Support) Kun 32
projects with its free end into a hole 33 in the ll1M section 15 of the outlet tube 14.

Reference number 34 is the population opening 35 of the circumference of the population portion 28a.
The inlet conduit is shown terminating within the outer cylindrical portion 22' and extending through the outer cylindrical portion 22' in a direction generally perpendicular to the longitudinal direction of the passageway 28. The external part of the artificial conduit 34 is formed by a tube piece 36 which projects from the section 22 to serve as a fitting for a hose 37 which is inserted into the tie container 25 upon mounting the device 10 onto the container.

Reference numeral 38 designates an opening in plate 16 which serves to communicate between valve chamber 28c and the interior of pressure chamber 19. The outlet portion 28b of the passageway 28 communicates with an elongate outlet conduit 39 formed in the tube 14 and terminates in a downwardly directed discharge opening 40 at the outer end of said tube Ω.

The method of operation of the above dispensing device will be explained below.

The valve device formed by the elastically flexible funnel-shaped flange 29 acts as a one-way cell. Said valve device operates in a suitable manner so that the two lower annular projections 41 each one in the passage 28
One valve device is provided after each of the valve devices. When the pressure method 19- is compressed, a temporary overpressure will occur in the valve chamber 2Bc. This overpressure will cause one of the two valve devices located proximate the inlet portion 28a to form a hermetic seal against the cooperating projection 41 and the adjacent circumferential wall portion of the valve chamber 28C. At the same time, the other valve arrangement 29 located close to the outlet section 28bK will be biased elastically to the right in FIG. This allows the latter valve device and passage 2

When the pressure method 19 is then released: the valve chamber 28 is brought back into sealing contact with the projection 41 cooperating with the valve device 29 located close to the outlet portion 28b, such that a temporary vacuum
The valve device established in c, while located close to the inlet portion 28a, instead of biasing elastically toward the right in FIG. Artificial part 28 with an amount of liquid or pasty product to
a to refill the outlet section 28b. The inlet portion 28a is continuously connected to the interior of the container 25 through an outlet conduit 34 and a hose 37 which preferably extends to the bottom of the container 25.

If the dispensing device is instead attached to the shaft section at the lower end of the container, the discharge tube 14 is rotated 180 degrees to bring the discharge opening 40 on the same side as the pressure tube 19. In order to allow the discharge tube 14 to rotate in the manner described above while remaining substantially safely within the valve housing, the end portion 15 of said tube has an annular lower protrusion which engages within an internal groove 43 within the valve housing 11. It has 42.

The invention is not limited to the embodiments described above and shown in the drawings. Alternatively, many modifications may be made within the scope of the invention. For example, the discharge tube need not have a radial discharge opening. Alternatively, the discharge opening has an end face of the tube. In this case, the discharge pipe does not need to be rotatably attached to the valve housing.
