NOZZLE EQUIPPED VALVE OUTLET FOB. CONTAINERS John Coyle and William F. Punte, Baltimore, Ma, assignors to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application March 20, 1946, Serial N0. 655,864
2 Claims.
Our invention of which the following is a detailed specification relates to nozzle equipped valve outlets for containers suitable for the packaging, transport and dispensing of fluids under superatmospheric pressure. Such devices find wide application in the packaging of fluid food stufis, beverges, condiments, dressings and the like. They are also of distinct advantage in,
the convenient handling of vaporizable fluids such as perfumes, deodorants, insecticides, aerosols and Similar fluids.
In the packaging of such materials, it is most desirable to use sheet metal containers such as cans with suitable adaptation for dispensin the contents. It is, however, necessary to simplify the construction and economize the manufacture of the devices.
An object of our invention is to provide a convenient and economical valve outlet for containers of fluids under pressure. In providing such a device it is, of course, essential that the outlet be capable of receiving a cap which will protect the outlet and prevent escape of the contents during shipping and storage in stacks.
One object of our invention is to provide such an outlet within the overall dimensions of the container for better security against damageand convenience in economical packing.
A further object of our invention is to provide a readily attachable nozzle which will replace the storage cap.
A further object of the invention is to provide means in the nozzle to direct the discharge of the contents as a. spra or the like over the beaded rim of the container.
A still further object of our invention is to provide novel means by which the nozzle is sealed against leakage during discharge through the outlet and for confining the discharge through the nozzle alone.
For the purpose of example we have illustrated the preferred form of our invention in the accompanying drawings in which:
Figure l is a vertical cross section of the combined valved outlet and detachable spraying nozzle;
Figure 2 is a top plan view of the valve shell itself;
Figure 3 is a top plan view of the spray nozzle, and,
Figure 4 is a. top plan view of the valve showing the notches and prongs by means of which the gasket is secured to the valve plate.
In the drawings, the sheet metal container or can has been illustrated fragmentally at 6 by the I cylindrical and relatively showing of part of the concave pressure head by which the container is adapted to hold fluids under superatmospheric pressure.
Centrally of the head 6 there is a depressed ofi-set circular flange 1 within which the outlet fixture is attached and hermetically sealed by solder bonding, welding or other suitable means to effect a. pressure-proof seal between the flange land the rib 9 of the shell 8. This outlet fixture comprises a shell 8 which is generally low.
The base of the shell 8 is formed with an outwardly projecting rib 9 terminatin in an inwardly directed flange I0. This forms a cir cular groove in which there is permanently held a disc II which seals oif the contents of the container except for discharge through eduction or draft tube l2. The tube I2 is permanently attached centrally of the disc I! and extends to the opposite or bottom end of the can in such manner as to evacuate all of theflud contents of the container.
On opposite sides of the shell 8, the latter is expanded to provide a pair of nibs l3. These nibs are adapted to receive a sealing cap not illustrated but of conventional form having a bayonet fastening engaging the nibs and wholly below the cans rim. In this way the shell 8 may .be suitably and conveniently sealed and protected after being sealed to prevent lOss of the can contents during storage and shipping.
.The top of the shell :8 is depressed to form a flat valve seat ll with an the shell.
The valve plate I5 is mounted for vertical sliding movement within the shell 8. The plate has a plurality of upturned prongs l6 which extend upwardly through notches in a flat valve gasket or facing l1 and are bent back on to the upper face of said gasket for firmly securing the same to the valve plate l5. -This gasket or facing l1 forms with the valve seat H a gas-tight and liquid-tight seal. The valve is held against the seat by means of a coil spring l8 under compression between the valve plate 15 and the disc II. Clearance is provided between the inner wall of the shell 8 and the perimeter of the valve gasket ll. These slots in the valve gasket and the clearance mentioned provide a passage through which the liquid contents of the can will pass when the valve is unseated.
A dispensing head I! is provided having a depending skirt 20 which engages over and is removably attached to the outlet shell 8. Bayonet slots 2| of which the horizontal portions axial opening through- 3 only are shown in Fig. 1 permit the skirt 20 to be slipped down over the shell 8 and by partial rotation securely attached to the latter by means of the locking nibs l3. A ring gasket 22 fitted within the spray cap at the top of the depending skirt 20 forms a seal between the latter and the top of the outlet shell 8.
A spray nozzle 23 projects obliquely from the body of the dispensing head l9 and a discharge passageway 24 extends through the nozzle from the central portion of the depending skirt 20, the inner end of this discharge passage 24 overlying the central opening in the ring gasket 22.
A valve operatingplunger 25 is slidably mounted in a bore disposed centrally of the dispensing head ISr'The outer end of the plunger is reduced and riveted to a spreading head 26 adapted to be depressed by finger pressure. A compressible resilient collar 21 fits tightly around the plunger 25 and occupies the space between the head 26 and the body of the dispensing head [9. It seals the bore in the spray cap and eliminates need for special packing and the like. This collar is dimensioned so as to hold the lower end 28 of the plunger 25 spaced a slight distance from the valve facinggasket I! when the valve is in non-operating position.
In order to prevent removal or loss of the plunger 25, the lower end 28 is upset or spread to form a limit stop in the manner indicated in Figure 1.
The use of the outlet and the dispensing head will be clearly apparent from the above description. In packaging, storage and shipping the outlet forms a part of the metal can. It is adapted to be capped in any suitable manner for example, by means of a bayonet cap as described.
It will be understood that the capped outlet is proof against accidental leakage and is contained within the limits of the plane of the rim of the container.
At the point of use, the outlet is uncapped and I the dispensing head attached to the shell 8. This does not disturb the seal providing the plunger head is held against inward movement.
However, by the removal of any such holding means as the clip above described, the plunger may then be depressed against the compression of the collar 21. The lower end of the plunger 28 engages the valve facing l1, unseats the valve and permits the discharge of the fluid under pressure through the spray nozzle 23. In this operation, leakage around the dispensing head is prevented by the gasket 22. At the same time compression of the resilient collar 21 serves as an efficient gas tight packing for the plunger 25.
The discharge from the nozzle 23 ,may be in the form of liquid or vapor. In either case the discharge will .be directed to a point over and beyond the rim of the head 6 and may be directed in the desired manner.
On release of pressure on the plunger head 28, the resilient collar withdraws the lower end 28 and permits the coil spring I8 to bring the valve facing ll into sealing contact with the valve seat I 4.
While the preferred embodiment has been described above, it will, of course, be understood that the invention may be embodied in diverse structures of differing proportion, structural details and materials without departing from the 4' I scope of the invention as set out in the following claims:
We claim:
1.
