7 Claims. (Cl. 22283) This invention relates to a dispensing device, and especially to adispensing devicefor receptacles which have to be hermetically closed during storing.

For storing volatile fluid or gaseous mediums such as poisonous liquids or gases, i. e. condensedgases, medical goods, inflammable substances, cooling agents and fire extinguishing means in such a manner that any loss through leakage or any contact with the atmosphere or other substances can be avoided, it .is known to use hermetically closed receptacles or containers Which instead of having an ordinary .cock vor valve which maybecome more .or less leaky, is provided with .an outlet which is blocked by a tight preferably metallic blocking wall welded or soldered to the outlet, and .whichcontainers are further provided with elements which can be operated from the outside of the receptacle or container to cut or punch through the blocking wall when the receptacle or container isto be emptied.

:Further, it is known to usehermeticallyclosedreceptacles or containers provided interiorly thereof with an opening member which by a deformation of one of the end bottoms of the container displaces the said member against the second end bottom so that the member in the last mentioned end bottom makes a hole through which the contents of the container may then be emptied. Such containers are, however, only suitablefor use once and are generally thrown away after having been emptied. Further it is difficult to provide a hermetically closed connection between a such receptacle and a receiver for its contents.

An object of the present invention is to provide a comparatively easily exchangeabledispensing device, particularly for use in connection with hermetically closed receptacles or containers as mentioned above; the dispensing device serves to close the receptacle or container during storing and to one emptying thereof; the dispensing device may be mounted on the receptacle or container before or after its filling with the medium to be stored.

Another object of the presentinvention is to provide a dispensing device which assures a hermetical closing of a receptacle during storing but nevertheless facilitates access to the contents thereof and emptying of the-receptacle without the receptacle being disturbed.

A further object of the present invention is toprovide a dispensing device which assures a hermetical closing of a receptacle during storing but-nevertheless makesit possible in a simple manner to produce a hermetically closed connection between the receptacle and a receiver for the contents thereof, which connection can be rendered effective after its establishment.

Still another object of the present invention isto provide a dispensing device with self-contained opening means which can be rendered effective through medium of pressure applied on said outletclosure from the exterior thereof.

A still further object of the present invention is to provide a dispensing device which in a tightfitting manner States Patent can be connected not alone to a receptacle but simultaneously to a receiver for the contents of the receptacle and which has self-contained means for producing connection between the receptacle and the receiver only by application ofpressure on the outlet closure.

Another object of the present invention is to provide a dispensing device which assures hermetical closing of a receptacle but nevertheless a simple opening thereof when its contents has to be used, and which may be manufactured independently of the receptacle for which it is intended.

Still another object of the invention is to provide a dispensing device for hermetically closed receptacles, which closure is simple to open, comparatively cheap to produce and easily can be arranged on and anew removed from the receptacle, so that after use it may be thrown away.

With this and other objects in view the invention relates to a dispensing device in which a housing, the walls of which are entirely or partly made from a comparatively easily deformable material, is in similarity with a valve housing provided with inlet and outlet openings of which at least one opening is closed or blocked by means of a pierceable blocking wall, and in which the housing interiorly is provided with an opening member having a cutting edge facing the blocking wall and being arranged with its cutting edge to punch or cut through the blocking wall when the housing is compressed.

The invention will now be described more in detail with reference to the accompanying drawings illustrating by ways of examples embodiments of the invention.

In the drawings:

Fig. 1 is a longitudinal sectional view of an embodiment of the dispensing device with a straight passage, in closed position,

Fig. 2 is a corresponding longitudinal view of an only slightly amended embodiment of the invention in open position,

Fig. 3 is a section taken on line 33 in Fig. 1, and

Figs. 4 and 5 are longitudinal sectional views corresponding to Figs. 1 and 2 of another embodiment of the present invention having an angular passage.

In the embodiment of my invention shown in Figs. 1 and 2 10 indicates a ball-shaped or lens-shaped housing of a deformable material such as brass, copper, soft sheetmetal, plastic or the like materials. This housing it comprises two diametrally disposed pipe-shaped branches l2 and 14, of which the branch 12 is closed in a tight-fitting manner by means of a thin blocking wall 16 preferably made from the same material as the housing 10. This blocking wall 16 may, when desired, without diificulty be punched or cut through by means of an opening member or piercing tool 18 consisting of a pipe section 20 one end 22 of which extending into the branch 12 has been obliquely cut off thus forming a cutting or piercing edge 24, facing the blocking Wall 16. The other end 26 of the piercing member 18 is secured to or loosely disposed disposed in the branch 14. The branch 12 extends in the embodiment shown into and is for example by means of a packing 28 or by soldering in a tight-fitting manner connected to an outlet pipe 30. The branch 14 receives and has secured to it in a tight'fitting manner for example by means of a packing 32 or by soldering the free end of an outlet pipe or neck 34 of a receptacle 36 for storing of a medium which is later to be emptied through the dispensing device. The neck 34 extends up to and abuts against the end 26 of the opening member 18, which as will be especially seen in Fig. 3 is provided With a lengthwise slot 38 at its top.

In Fig. 1 the dispensing device is illustrated in its normal blocking position in which the cutting edge 24 of the member 18 is positioned in immediate vicinity of the blocking wall 16 in the end of the branch 12. The dispensing device is opened by compression, namely by means of a pair of tongs or another simple tool, which moves member 18 from the position shown in Fig. 1 to the position shown in Fig. 2, whereby the opening member 18 abutting against the neck 34 is axially displaced, whereby the cutting edge 24 pierces the wall 16 by cutting out a disc 4-9 from the wall, said disc having a diameter corresponding to the outer diameter of the member 18.

The disc 40 is released from the wall along its entire circumference save the portion disposed opposite the slot 38 in the opening member 18 by means of which portion the disc 40 remains connected to the wall 16 although bent upwards as indicated in Fig. 2. Thus, there is provided a free passage for the medium in the receptacle 36, which medium flows into and through the opening member 18 and continues through the hole provided in the blocking wall 16 and the discharge pipe 30 which is supposed to be axially displaceable together with the branch 12 of the housing 10.

The above described dispensing device can also be arranged in such a manner that the branch 12 of the housing 1 is connected to the receptacle 36 and the branch 14 to a discharge pipe.

As to all essential the embodiment shown in Fig. 2 corresponds to the embodiment shown in Fig. 1, but it differs slightly from the latter thereby that between the neck 34 of the receptacle 36 and the end 26 of the opening member 13 an abutment ring 4-2 is inserted in and connected to the branch 14. This abutment ring assures the displacement of the opening member 13 during the compression of housing 10 independent of the placement of the neck 34 in the branch 42. Since this abutment ring 42 prevents a backward displacement of the opening member 18, it is not necessary that the neck 34 is inserted in the branch 14 as shown, but the branch 14 may be inserted in the neck 34 in a pluglike manner.

The outlet closure shown in Figs. 4 and 5 comprises a housing of ordinary, not compressible material, such as casting. The housing is open at the top where it is covered in a tight-fitting manner by a domed, for instance a semiglobular cover or cap 44 of a deformable material. One end of the tubular opening member abuts against or is secured to the inner side of the said cover or cap, whereas the other end of member 18, which end is provided with the cutting edge 24, extends down into and is guided in the tubular branch 12 projecting from the bottom of the housing 19, and which is slightly closed by the blocking wall 16 immediately in front of the cutting edge 24. The branch 12 extends down into and is tightly connected to a sleeve 46 on an outlet pipe 48. The housing 10 is on one side provided with a branch 14 which can be connected to a pipe or a tubular neck 34 or the like on the receptacle 36 for the medium.

in Fig. 4 the outlet is shown in blocking position and in Fig. 5 in open position, in which the opening member 18 has been axially displaced by a downwardly directed pressure on the cover or cap 44 and has pierced the blocking wall 16 in a manner corresponding to the one described in connection with the embodiments shown in Figs. 1 to 3. The medium will now flow from the container to the housing 10 and continue through the slot 38 into the tubular opening member 18 from where it leaves through the pipe 48. The emptying may also take place in the opposite direction if the branch 12 is connected to the receptacle instead of the branch 14.

With regard to the nature and the quantity of the medium to be transferred from a container to a receiver for the medium within the scope of the appended claims the dispensing device according to the present invention may be shaped in many other ways than described above.
