Abstract

A device for filling a container of the disposable type with a gas which includes a frame, a vertically movable container support attached to the frame and rotatable about a central axis, a bell attached to the frame and rotatable about the central axis, and a stationary center portion sealingly directed relative to the bell. The bell has a circular sealing portion on the lower extremity thereof eccentrically mounted with respect to the central axis which is connectable to the filling opening of a container. The stationary center portion is comprised of a sealing means and a filling pipe. The filling pipe is vertically movable and alignable with the circular sealing portion of the bell. The sealing means also is vertically movable and alignable with the circular sealing portion of the bell for capping the container after it has been filled.

Patented Oct. 23, 1973 6 SheetsSheet 5 The present invention relates to a device for filling a container of the disposal type with a gas, such as liquid gas, said device being provided with a bell which may be positioned in a sealing manner on the upper side of a container, said upper side being provided with an opening, said bell being provided with means for supplying the gas as well as with a vertically movable sealing device with which a sealing may be placed and locked in the opening of the container after the filling operation. A device of this kind is known from e.g. German Pat application No. 1.163.869, laid open to public inspection, which refers in particular to the loading of an expelling gas with a so-called aerosol container, filled with a different medium to be delivered. The loading of the expelling gas merely requires an efficient sealing of the bellover thetop of the container. to be filled and sealing under pressure. Aerosol containers of this kind usually have a small volume and the expelling of air before the loading of the generally inert gas is no problem. However, should this be the case, e.g. when a container has to be filled with liquid gas, the known device is less suited for the object in mind.

It is knownfrom French Pat. No. 1.527.201 to fill a container of that kind also under-a bell with a liquid gas, because the container has been provided beforehand with a tap which is opened primarily to evacuate the container and subsequently for the supply of the liquid gas. As this will mean that the filling has to take place through the tinyorifice of the tap, said filling operation will take considerable time.

The object of the invention is to provide a device with which the filling of containers with gas, in particular the filling with liquid gas, can take place fast while expelling with certainty the air being present in the container.

In accordance with the invention, said object is achieved in that the bell is rotatable about a central axis of the device relative to the filling and sealing means, said filling means consisting of a vertically movable filling pipe, the central axis of which being at the same rafilling pipe said pipe is lowered close to the bottom of v the container, as a resultof which the filling may take place from below and the inflowing gas will expel the air, if any, that may be present. The filling pipe is then lifted again and the bell with the container can be rotated to such an extent that the sealing means may be put into operation to place a seal in the filling opening.

vThe invention will now be described more in detail with reference to the accompanying drawings, which illustrate by way of example one embodiment of the invention, wherein FIG. 1 up to 6 inclusive show the device according to the invention in various positions.

Said device consists of a frame l-with a table 2 with up and down, movement along the bars 1, said table may be operated by means of the cylinder 3. The table 2 has a table 5 being rotatable about the central axis 4,

on which table a container 6 is placed which has to be filled. A bell 7 is located in the top of the frame 1, said bell being rotatable about the central axis 8 which corresponds with the central axis 4. The bell has a circular sealing portion 9 which may connect to the upper side of the container concentrically relative to the opening 10. The bell is rotatable relative to a stationary portion 16 which also is sealingly directed relative thereto. Stationary centre portion 16 comprises the sealing means 11 and the filling pipe 12. Said sealing means may be operated in a known manner by means of

cylinders

13 and 14 and the filling pipe may be moved up and down by means of cylinder 15. I

In the starting position illustrated in FIG. 1 the table 2 is moved upward until the sealing portion 9 will press tightly on the upper side of the container 6. The bell and the rotary table are then rotated until the position is reached as shown in FIG. 2, in which'the fillinghole 10 is positioned under the filling pipe l2.-Said filling pipe will then be moved down, as shown in FIG. 3,

close to the bottom of the container to be filled. When the filling operation has taken place, the filling pipe will return again to its starting position, as shown in FIG. 4, whereupon the rotary table and the bell, as shown in FIG. 5, will return to the position in which the filling hole is located under the sealing means.

FIG. 6 illustrates the insertion of a cap which may then be secured in the opening, e.g. by expansion in a v manner known as such. It is, thus, possible to fill containers of a large volume within a very short period of time.

What is claimed is:

1. A device for filling a container of the disposable type with a gas comprising a frame, a vertically movable container support attached to said frame and rotatable about a central axis, a bell attached to said frame and rotatable about said central axis, said bell having a circular sealing portion on the lower extremity thereof eccentricallymounted with respect to the central axis which is connectable to the filling opening of a container and being sealingly directed relative to a .stationary center portion comprising a sealing means and a filling pipe, said filling pipe being vertically movable and alignable with the circular sealing portion of the belland said sealing meansbeing vertically mov-
