Description

The invention relates to a disposable container having a receiving space for receiving a liquid or pasty medium, which disposable container has a jacket, a support with a collecting area for the medium and a shaft extending from the collecting area to a provided in the shell passage opening, wherein the duct and the passage opening is passed through a conduit which connects the collecting area with a discharge opening for the medium, and wherein the conduit comprises a hose and a shut-off device. Furthermore, the invention relates to a device for dispensing a liquid or pasty medium, with such a disposable container and with a pump having a suction port and an outlet port for the medium, wherein the suction port is arranged on a suction pipe.

Such a disposable container for receiving pasty media, such as emulsion paints, spray plaster spatula, synthetic resin products or silicone resin plasters is made DE 20 2004 010 486 U1 known. The jacket and the support of this disposable container are made of cardboard and are coated on their side facing the medium with an inliner. The support is disposed within the shell sloping down to a collection area. Set below the collection area of the liner is designed tubular and leads through a provided in the disposable container shaft to a jacket passing through the connection flange. The connection flange has a discharge opening, closed with an aluminum foil, for the passage of the medium. In addition, an external thread is arranged on the connecting flange, onto which a matching internal thread of a cock can be screwed. The aluminum foil is displaced from the tap in such a way that it tears. On the outside of the cock, a lever is pivotally mounted, which is connected to a valve located in the interior of the cock, in an open and a closed position pivotable. At its end remote from the internal thread, the cock has an outlet opening for the medium, to which a suction tube of a pump for sucking off the medium located in the disposable container can be connected. However, the tap has proven to be susceptible to interference when used on construction sites. It is also unfavorable that air can be contained in the hose-shaped section of the inliner connecting the receiving space to the discharge opening after the disposable container has been filled with the medium. After the pump has been connected to the discharge port, this air enters the pump, which can interrupt the pumping process. The pump must then be vented, which requires a considerable amount of work and has delays in the work progress on site.

It is therefore the object to provide a disposable container and a device of the type mentioned, which allow easy us reliable handling.

This object is achieved with respect to the disposable container, characterized in that the shut-off device is designed as a hose clamp, which is arranged for disconnecting the hose at a remote from the collecting region free end portion of the hose at a distance from the discharge opening, that the hose with its free end portion on a suction pipe a pump can be pushed or pulled, and that the dimensions of the passage opening and the shaft are adapted to the dimensions of the hose and the hose clamp, that the free end portion of the hose together with the hose clamp through the passage opening into the shaft introduced and pulled out of this is.

In a device of the type mentioned above, the above-mentioned object is achieved in that the outer cross-sectional dimensions of the suction tube are adapted to the inner cross-sectional dimensions of the free end portion of the tube, and that the intake port having the suction pipe through the discharge opening into the free end of the Hose can be introduced and pulled out of this.

Advantageously, the shut-off device can thus be designed to be very simple and robust, so that it allows trouble-free operation of the disposable container, in particular on construction sites over the entire life of the disposable container. During transport of the disposable container, for example, to the construction site of the hose and the hose clamp may be arranged in the shaft, so that they do not protrude outwardly beyond the outer surface of the shell. As a result, the disposable container can be accommodated in the smallest possible space and the hose and the hose clamp are protected against damage during transport in the shaft or the space bounded by the jacket. Once the disposable container is placed at the point of use, the free end of the hose and the hose clamp arranged thereon can be pulled out of the jacket through the passage opening of the jacket in order to connect the hose, for example, to a suction pipe of a pump.

In a preferred embodiment of the invention, the free end region of the hose is connected to the collecting region via a hose section connected, wherein the hose portion is designed such that it has a greater dimensional stability than the free end portion of the hose. The hose clamp can then be operated with little effort at the free end portion of the hose and yet the hose is largely dimensionally stable in its connected to the collection area hose section. As a result, the liquid or pasty medium can be conveyed from the receiving space to the discharge opening with little loss. When the hose clamp is closed, tight sealing of the hose is made possible due to the compliance of the free end region, preferably made of an elastomer material such as rubber.

In an advantageous embodiment of the invention, the hose has a hose jacket made of an elastomeric material which extends integrally over the hose portion and the free end portion of the hose, wherein the hose at least one, embedded in the elastomeric material or otherwise connected to this Inner cavity bounded by the elastomer material has wholly or partially circumferential reinforcement which extends only in the hose section, but not in the free end region of the hose. In this case, the reinforcement is preferably designed linear, wire or fibrous with a plurality of turns offset from each other in the axial direction of the tube. The reinforcement can in particular ring-shaped, helical and / or spiral around the inner cavity.

In an expedient embodiment of the invention, the hose clamp on each other and movable away from each other on jaws, between which the hose is arranged. It is even possible that the hose clamp is designed as a spring clip, wherein the jaws are integrally connected.

In another advantageous embodiment of the invention, the hose clamp on a sling or a band, which or which is guided around the hose and positioned against the outer wall of the hose or positionable. The loop can be designed as a cable tie.

It is advantageous if the disposable container below the support has a bottom structure having a plurality of hollow chambers arranged side by side in a horizontal plane, between which side walls are provided, which are interconnected by a bottom plate, and if the shaft is formed between the side walls. This results in a mechanically stable soil structure, over which the support is supported on the ground and in which the hose is protected in the shaft from mechanical damage.

Conveniently, the tube portion adjacent the collecting area has a curvature point with a change in direction of preferably about 90 °, wherein the point of curvature is connected via a straight hose portion with the free end portion of the tube. At the point of curvature, the flow of the medium conveyed through the hose can be deflected with little loss in the lateral direction and then conveyed on a straight path to the discharge opening. The hose is preferably designed as a corrugated tube. This allows easy installation of the hose.

Preferably, a threaded ring is arranged at the end of the hose facing the collecting area, which can be screwed to a mating mating thread of a connecting piece arranged on the collecting area. The disposable container thus allows easy and quick installation.

In an advantageous embodiment of the invention, the receiving space is bounded by an inliner, which is tightly connected to the connecting piece, in particular welded or potted. As a result, a disposable container constructed cost-effectively, in which the jacket, the support and / or the floor structure can be made of cardboard, is made possible.

The disposable container described above may be part of a device for dispensing a liquid or pasty medium, which in addition to the disposable container comprises a pump having a suction port and an outlet port for the medium, wherein the suction port is disposed on a suction pipe and wherein the outer cross-sectional dimensions of Suction tube are adapted to the inner cross-sectional dimensions of the free end portion of the hose, that the suction port having the end of the suction pipe through the outlet opening into the free end region of the hose can be introduced and pulled out of this. In an advantageous manner, the suction pipe can then be inserted into the hose at the beginning of the pumping process with the suction opening, so that medium can be sucked in closely adjacent or even directly below the collecting area. As a result, the pump can still reliably convey the medium even if air should be trapped in the tube. This eliminates a cumbersome bleeding the pump and / or the hose.

If necessary, the hose can have slightly smaller internal cross-sectional dimensions than the corresponding outer cross-sectional dimensions of the suction pipe, so that the elastomer material of the hose must be slightly widened when mounting on the suction pipe. In the assembly position, the hose is then pressed by the restoring force of its elastomeric material to the outer circumferential surface of the suction pipe, which allows a good seal of the hose to the intake manifold. If required, the first tube section can also be pressed against the suction tube by means of a hose clamp, a cable tie or similar tensioning means,
In an advantageous embodiment of the invention, the length of the suction pipe is greater than the length of the free end region of the hose, so that the suction pipe can be inserted through the end region of the hose into its hose section. As a result, when pumping the medium, disturbances of the pumping process due to air pockets in the hose can be suppressed even more reliably.

It should also be mentioned that the support within the shell can be arranged sloping towards the collecting area in such a way that the disposable container can be completely emptied.

Hereinafter, an embodiment of the invention is explained in detail with reference to the drawing. It shows:
