Application February 6, 1934, Serial No. 710,005
This invention apertains to new and useful improvements in paste tubes of the collapsible tube type.
The principal object of the present invention is to provide a paste tube having a closure wherein the closure will automatically open when the tube is compressed so as to emit a ribbon of paste.
Another important object of the present invention is to provide a paste tube of the collapsible type wherein the closure will automatically open when the tube is compressed and automatically close when the tube is released.
These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.
} In the drawings:-
Figure 1 represents a side elevational view of the tube closure in closed position.
Figure 2 represents a front elevational view the tubeand closure.
Figure 3 represents a side elevational view showing the closure in open position.
Figure 4 represents a front elevational view showing the closurein open position.
Figure 5 represents a vertical sectional view taken substantially on line 5-5 of Figure 2, showing the closure proper in elevation- Figure 6 represents a rear elevational view of the tube and closure.
Figure '7 represents a sectional view taken substantially on line 7--'7 of Figure 4.
Figure 8 represents a sectional view taken substantially on line 8- -8 of Figure 1.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the collapsible tube having the neck portion 6. As is clearly shown in Figure 3, this neck portion is cut off obliquely, as at 7, and has an upwardly converging flange portion 8. The innermost portion of the outer end of the neck 6 is provided with a groove 9 in which engages the boss 10 of the closure 11 and a pin 12 goes through this boss and pivotally connects the closure 11 to the neck 6.
The closure 11 has a stopper portion 13 which is engageable into the neck, thg upper portion of which is on an arc 14 of a circle having its axis at the rod or pin 12.
The stopper portion 13 has a groove 15 therein gradually deepening toward the upper portion of the closure, so that when the closure 11 is forced upwardly by the pressure of the tube contents when the tube is compressed, a ribbon 16 of. paste will emanate from the neck 6.
The outer ends of the rod 12 have a spring member 1'7 coiled around the same, as at 18, the portion 19 of this spring being disposed over the top of the closure 11, while the ends of this spring are brought together at the back of the 75 neck 6 and twisted to connect, as at 20.
While the foregoing specification 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 is:
. A collapsible tube having a neck portion, a swingably mounted closure on the neck movable to an open position by the compression of the tube, a spring mounted on said neck and closure normally urging the closure to closed position, said closure being provided with a stopper-like prominence and a grooveway in the said prominence through which paste can be forced by internal compression of the tube to form a ribbon of the discharging material.
