CLOSURE FOR COLLAPSIBLE TUBES Filed Aug. l5, 1951 INVENTOR. WWA/QD /T MURPHY @www ATTV.'
CLOS FOR COLLAPSHBLE TUBES Edward F. Murphy, Chicago, lll.
Application August 3, 1951, Serial No. 240,176
1 Claim. (Cl. 222-509)1 The present invention relates to improvements for closures such as may be used for collapsible tubes, such tubes being normally used for tooth paste, shaving cream, art paint, etc.
The principal object of the present invention is to provide a valved closure for collapsible tubes, to the end, that the closure or cap need not be removed, after it is once applied, thus precluding the likelihood of misplacing said cap as frequently occurs now when using collapsible tubes containing tooth paste, shaving cream, art paints, etc.
Another object of the invention is to provide a valved cap for collapsible tubes wherein the valve means can be readily operated to permit the discharge of the contents of the tube.
Still another object of the invention is to provide a valved cap for collapsible tubes, wherein the valve is so constructed as to preclude the likelihood of the valve sticking or otherwise becoming defective by reason of its contact with the contents of the tube.
These and various other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawing:
Figure 1 is a vertical sectional view through the cap and neck portion of a collapsible tube.
Figure 2 is an end elevational view of the cap.
Figure 3 is an end elevational view looking at the opposite end from that shown in Figure 2.
Figure 4 is a fragmentary vertical sectional view showing the valve in opened position.
Figure 5 is a fragmentary vertical sectional view through the cap with the mechanical parts removed.
Figure 6 is a side elevational view of the valve and operating means.
Referring to the drawing wherein like numerals designate like parts, it can be seen that reference character A denotes a conventional collapsible tube, such as is used for containing tooth paste, shaving cream, art paint, etc. and this tube has an externally threaded neck B, which is conventional.
The present invention is generally referred to by numeral 5 and consists of a cylindrical cap 6 having a thickened lower apron portion 7, internally threaded to engage the threads of the neck B.
The cap 6 has a thickened top portion 8, certain side portions of the cap 6 sloping upwardly to this thickened portion 8 as shown in Figure 3.
The thickened portion 8 has a cylindrical bore 9 in which a plunger 10 is slidable and this plunger 10 has a A(le reduced nipple 11 capable of fitting within a small orifice 12 at one end of the thickened portion 8 and the lower portion of the thickened portion 8 adjacent the orifice 12 has a port 13 through which the contents of the tube A can pass to reach the orifice 12 when the plunger 10 is retracted.
The plunger 10 has a rigid rod 14 projecting from its inner end and extending through the bearing 15 to normally extend outwardly into a pocket 16 at the opposite end of the thickened portion 8 and at this point, the rod 14 pivotally connects to a hand lever 17, which is rockably connected to an ear 18 on the back wall of the pocket 16.
A coiled compression spring 19 is disposed around the rod 14 and interposed between the inner end of the plunger 10 and the bearing 15, as is shown in Figure 1 and also in Figure 6.
It can now be seen, that by pressing inwardly on the lower portion of the lever 17, the rod 14 will be pulled outwardly removing the nipple 11 from the orifice 12 and when pressure is exerted on the tube A, the contents of the tube will pass through the port 13 and orifice 12.
When the lever 17 is released, the spring 19 will force the plunger 10 to left in Figure 1, resulting in the nipple 11 entering the orifice 12 and securely closing off the outlet of material and leaving a clean exterior of the cap 6. Very little wiping off, if any, will be necessary from time to time to remove any particles that might excrete through the orifice 12 as the plunger 10 moves to closed position.
While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention what is claimed as new 1s:
A device of the character described comprising a cap having an internally threaded skirt for mounting upon a paint tube, and a relatively thick upper portion having a transverse cylindrical bore through one side to a point adjacent the other side thereof, said other side of said thick portion having an orifice therein and said thick portion having a port communicating with the interior of sad cap adjacent said orifice, a cylindrical plunger slidably mounted in said bore, a nipple atiixed to one end of said plunger and receivable in said orifice, a bearing mounted in said bore at that end thereof remote from said orifice, a rod atiixed to said plunger and extending through said bearing, a lever mounted upon the outer side of said cap and pivotally connected to said rod, and a spring surrounding said rod and bearing at one end against said bearing and at its other end against said plunger.
